Description

Building structure, sleeve structure and building method

The present disclosure relates to a building structure and a building method, and in particular to a building structure and a building method comprising a systematic metal formwork.

The process of building a reinforced concrete structure on a construction site involves multiple concrete pouring and curing processes. Before pouring concrete, it is necessary to set up formwork on the foundation or on the cured concrete base to provide and define the space for pouring concrete. For example, to shape a beam, column or wall, multiple formworks are first connected and fixed to each other to form the shape of the reinforced concrete structure to be shaped, and then concrete is poured between the formworks. After the concrete between the formworks is cured to form a structure, the formworks are removed from the structure.

The formwork can be metal formwork, wood formwork or plastic formwork. Metal formwork can be aluminum formwork. Aluminum formwork has the characteristics of light weight, high load-bearing capacity, simple installation, few joints, good stability, variable shape, smooth cast concrete, long service life, high recycling rate, etc. It can be reused about hundreds of times. In addition, the construction method of standardized formwork is simpler than that of wood formwork, and new apprentices can also get started quickly, which helps to inject new blood into the formwork industry and improve the shortage of formwork masters. It has three advantages: economic benefits, site safety and solving the manpower gap. Therefore, aluminum formwork is gradually widely used in the industry. In a small number of locations where aluminum formwork cannot be used alone due to special shapes, plastic formwork or wooden formwork can be used in combination with aluminum formwork to form a formwork system.

When the formwork is built to a certain height, a fence needs to be built to ensure that workers will not fall from a height during construction, which may cause public security concerns. The industry is looking forward to providing a fence facility that can be quickly and securely installed on the metal formwork (such as aluminum formwork) after it is positioned.

In order to solve the above technical problems, this application discloses a building structure and a building method, which can simply and conveniently set up a reliable safety guardrail on a structure built by metal formwork to improve the safety of construction workers.

The building structure disclosed in an embodiment of the present application includes: a plurality of first templates, each of which has a first side and a second side opposite to the first side, wherein the first templates are configured so that the first sides together define a first plane that is substantially perpendicular to a ground surface and is used to contact concrete, and the periphery of each of the first templates includes a plurality of connection holes therein; a plurality of sleeve structures, each of which has a long straight hollow body, the A hollow body has an opening at a first end and a bottom plate at a second end, wherein the sleeve structures are fixed to the first templates, and the sleeve structures are positioned so that the opening is farther from the ground than the bottom plate; and a guardrail structure having at least two first tubes passing through the openings of the sleeve structures and disposed in the hollow bodies of the sleeve structures, and at least one second tube spanning the first tubes and fixed to the first tubes.

The construction method disclosed in an embodiment of the present application includes: assembling a plurality of first templates so that a first side of the first templates jointly defines a first plane substantially perpendicular to a ground surface and used to contact concrete, the first template has a second side opposite to the first side, and the periphery of each of the first templates includes a plurality of connection holes therein; providing a plurality of sleeve structures, wherein each of the sleeve structures has a long straight hollow body, a first end of the hollow body has an opening and a second end has a bottom plate; fixing the plurality of sleeve structures to the uppermost periphery of the first templates or on the second side of the first templates so that the opening is farther from the ground than the bottom plate; at least two first tubes with a predetermined distance interval are respectively passed through the openings of the sleeve structures and arranged in the sleeve structures; a plurality of collars are provided, each of the plurality of collars includes a fixed end configured to be fixed to the first tubes, and a connecting end including a hole therein; the fixed ends of the plurality of collars are fixed to the at least two first tubes; and both ends of at least one second tube are respectively fixed to the first tubes by passing through the holes of the collars.

The above has been a fairly broad overview of the technical features of the present disclosure, so that the detailed description of the present disclosure below can be better understood. Other technical features that constitute the subject matter of the patent application scope of the present disclosure will be described below. Those with ordinary knowledge in the technical field to which the present disclosure belongs should understand that the concepts and specific embodiments disclosed below can be easily used as modifications or designs of other structures or methods to achieve the same purpose as the present disclosure.

The following disclosure provides a number of different embodiments or examples for implementing different features of the subject matter provided. Specific examples of components and configurations will be described below to simplify the disclosure. Of course, these are merely examples and are not intended to be limiting. For example, in the following description, "forming a first component over or on a second component" may include embodiments in which the first component and the second component are formed in direct contact, and may also include embodiments in which additional components may be formed between the first component and the second component so that the first component and the second component may not be in direct contact. In addition, the disclosure may repeat component symbols and/or letters in various examples. This repetition is intended for simplicity and clarity and does not in itself indicate a relationship between the various embodiments and/or configurations discussed.

In addition, for ease of description, spatially relative terms (such as "below", "beneath", "down", "above", "upper", "above" and the like) may be used herein to describe the relationship of one element or component to another element or components, as shown in the figures. In addition to the orientation depicted in the figures, spatially relative terms are also intended to cover different orientations of the device during use or operation. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein may also be interpreted accordingly.

As used herein, terms such as "first", "second", and "third" describe various elements, components, regions, layers, and/or sections, which should not be limited by these terms. These terms may only be used to distinguish elements, components, regions, layers, or sections from each other. Unless the context clearly indicates otherwise, terms such as "first", "second", and "third" used herein do not imply a sequence or order.

As used herein, the terms "substantially," "substantially," "essentially," and "about" are used to describe and explain small variations. When used in conjunction with an event or condition, the terms may relate to instances in which the event or condition occurred exactly as well as instances in which the event or condition occurred very approximately. For example, when used in conjunction with a numerical value, the terms may relate to a range of variation of less than or equal to ±10% of the numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, if the difference between two values is less than or equal to ±10% of a mean of the values (e.g., less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%), then the values may be considered "substantially" the same or equal. For example, "substantially" parallelism may involve an angular variation of less than or equal to ±10° relative to 0°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, "substantially" perpendicular may involve an angular variation of less than or equal to ±10° relative to 90°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

Unless otherwise specified, the horizontal or vertical mentioned in this article is usually relative to the ground of the building site. For example, "horizontal direction" refers to the direction roughly parallel to the ground; "vertical direction" refers to the direction roughly perpendicular to the ground; "horizontal height" refers to the distance from the ground.

The "inside" and "outside" mentioned in this article only express their relative relationship, not their absolute position or any direction. For example, "inside formwork group" and "outside formwork group" only express the relative relationship between the two formwork groups in structure, not specifically indicating that the inside and outside formwork groups are set at the formwork groups facing the inside or outside of the building base or any other specific position.

FIG. 1 shows a template 100 according to an embodiment of the present disclosure. The template 100 includes an upper plate 102, a lower plate 108, a left side plate 106, a right side plate 104, and a middle plate 110, wherein the periphery of the middle plate 110 is connected to one side of the upper plate 102, the lower plate 108, the left side plate 106, and the right side plate 104, respectively, and the length of the upper plate 102 and the lower plate 108 is greater than the length of the left side plate 106 and the right side plate 104, thus roughly presenting a long box shape with an opening. The upper plate 102, the lower plate 108, the left side plate 106, and the right side plate 104 each have a plurality of connection holes 112. In some embodiments of the present disclosure, the template 100 is a template made of metal, such as an aluminum mold.

FIG. 2 shows a building structure 1000 composed of a plurality of templates 100 according to an embodiment of the present disclosure. The plurality of templates 100 can use their respective left side plates 106 and right side plates 104 to abut against each other so that the plane defined by the first sides S1 of the templates 100 extends in the horizontal direction, or use the upper plates 102 and lower plates 108 of different templates 100 to stack each other so that the plane defined by the first sides S1 of the templates 100 extends in the vertical direction. The abutted or stacked templates 100 can be fixed together by passing through the corresponding connecting holes 112 of the templates 100 through appropriate fasteners 120, such as a bolt. In some embodiments of the present disclosure, the first side S1 of the template 100 is a plane for pouring concrete, and the second side S2 has a structure for fixing and supporting the template 100.

Building structures composed of metal formwork have various advantages. For example, compared with wooden formwork, the metal formwork is fixed on the opposite side of the concrete casting surface (i.e., the second side S2). When the building structure composed of metal formwork is used to cast a concrete ceiling, the construction workers perform the formwork fixing and supporting operations under the metal formwork plate, which has relatively high safety. In addition, on the side for concrete casting (i.e., the first side S1), the metal formwork can provide a flat and easy-to-clean surface.

In order to improve the safety of construction of a building structure constructed by metal formwork (regardless of whether the construction is performed on the first side S1 or the second side S2), this application discloses a building structure comprising a safety railing and assembled by metal formwork.

FIG. 3 shows a sleeve structure 200 for receiving a safety railing according to an embodiment of the present disclosure. The sleeve structure 200 has a long straight hollow body 206, one end of the hollow body 206 has an opening 202, and the other end has a bottom plate 204.

FIG. 4 and FIG. 5 show a building structure 2000 of an embodiment of the present disclosure, which is used for casting four concrete walls surrounding a space 2000'. The building structure 2000 is composed of a plurality of templates 100. A plurality of sleeve structures 200 are arranged at the periphery P1 near the uppermost side of the building structure 2000. At least two of the sleeve structures 200 are fixed to the template 100 at a predetermined interval. According to an embodiment of the present disclosure, the sleeve structures 200 are fixed to the second side S2 of the template 100 by welding. When fixed on the template 100, the openings 202 of the sleeve structures 200 are farther from the ground than the bottom plate 204. According to the embodiment of the present disclosure, when fixed on the template 100, the hollow bodies of the sleeve structures 200 are arranged perpendicular to the ground, and the openings 202 face upwards away from the ground.

5, a plurality of guardrail structures 300 are disposed on the template 100 via the sleeve structures 200. The guardrail structure 300 has a tube 302 and a tube 304 disposed parallel to each other, the tube 302 and the tube 304 pass through the opening 202 of the sleeve structures 200 and are disposed in the hollow body 206 of the sleeve structures 200, and the tube 306 and the tube 308 span the tube 302 and the tube 304 and are fixed to the tube 302 and the tube 304 at both ends. Although the guardrail structure 300 shown in FIG. 5 is composed of four tubes, the guardrail structure 300 may further include an unlimited number of tubes arranged parallel to the tubes 302 and 304, which are arranged on the building structure 2000 through an additional sleeve structure 200; and the number of tubes spanning horizontally is also not limited, and there may be only one tube 306, or more than three tubes spanning the tubes 302 and 304 and fixed on the tubes 302 and 304. The guardrail structure 300 can provide reliable support for construction workers. For example, when the space 2000' is reserved as an elevator shaft, the depth of the space 2000' will cause safety concerns for construction workers. At this time, the guardrail structure 300 can effectively prevent construction workers from falling into the space 2000'.

FIG. 6 and FIG. 7 show a building structure 3000 of another embodiment of the present disclosure. Similar to the building structure 2000 of the previous embodiment, the building structure 3000 can be used to cast a structure in which four concrete walls surround a space 3000'. The difference between the building structure 3000 and the building structure 2000 is that the building structure 3000 has at least one sleeve structure 200 disposed at the corner where the templates 100 are assembled, for example, FIG. 6 shows four sleeve structures 200 disposed at the corners. The advantage of arranging the sleeve structure 200 at the corner is that pipes extending in different directions can be fixed on the pipes disposed through the opening 202 of the sleeve structure 200. Please refer to Figure 7. Pipe 306 and pipe 308 are fixed on pipe 302. Pipe 306 and pipe 308 cross pipe 302 and pipe 304 and are fixed on pipe 302 and pipe 304. In addition, pipe 316 and pipe 318 are fixed on pipe 302, which extend at approximately right angles to pipe 306 and pipe 308. Pipe 316 and pipe 318 cross pipe 302 and pipe 320 and are fixed on pipe 302 and pipe 320, wherein pipe 320 is parallel to pipe 302 and is spaced a predetermined distance from pipe 302. Similarly, pipe 304 also has pipe 314 and pipe 315 extending toward pipe 322. The sleeve structure 200 for supporting pipe 320 can be set at the corner where the templates 100 are assembled.

According to an embodiment of the present disclosure, the pipes of the guardrail structure 300 are fixed to each other by a ring 310. For example, the pipes 306, 308, 316, and 318 are all fixed to the pipe 302 by the ring 310. The ring 310 includes a fixed end and a connecting end. The fixed end is configured to be fixed to the pipe 302. The connecting end includes a hole therein. Both ends of the pipe 306, 308, 316, or 318 are fixed to the pipe 302 by passing through the hole of the ring 310. According to one embodiment of the present disclosure, the collar 310 is a U-shaped structure, the two ends of the U-shape pass through the tube 302, and the curved portion of the U-shape covers the tube 306, the tube 308, the tube 316 or the tube 318 to fix the tubes on the tube 302, the tube 304, the tube 320, and/or the tube 322.

FIG8 shows another sleeve structure 400 of an embodiment of the present disclosure. The difference between the sleeve structure 400 and the sleeve structure 200 of the previous embodiment is that the bottom plate of the sleeve structure is an L-shaped bottom plate 404. The hollow body 406 of the sleeve structure 400 is a hollow rectangular parallelepiped. The L-shaped bottom plate 404 has a plate 408 and a plate 410 that are perpendicular to each other and connected. The plate 408 is fixed to one end of the sleeve structure 400 and closes the end. The plate 410 is fixed to one side of the hollow body 406 adjacent to the closed end. At one end relative to the closed end, the sleeve structure 400 has an opening 402 for receiving a pipe. The plate 408 extends horizontally beyond the area of the opening 402, that is, extends horizontally beyond the two parallel sides of the hollow body 406, and the plate 410 and the plate 408 have the same length in the longitudinal direction; the hollow body 406 can be vertically arranged at any position on the plate 408. At the extension of the two sides of the hollow body 406, the plate 408 and the plate 412 each have a plurality of through holes 412 and through holes 412', wherein the through holes 412 and through holes 412' have diameters that match the connecting holes 112 of the template 100.

FIG. 9 shows a building structure 4000 of an embodiment of the present disclosure. The building structure 4000 is composed of a plurality of templates 100, which form a substantially vertical plane for concrete pouring. The uppermost perimeter P1 of the building structure 4000 is substantially parallel to the ground of the construction base. Here, "uppermost" only means that there is no other template stacked on the perimeter P1, and does not represent an absolute position; in other words, in the same building structure or construction base, there may be other building structures formed by stacking a plurality of templates, the height of which is higher than the perimeter P1 from the ground of the construction base. According to an embodiment of the present disclosure, the positions of at least two of the through holes 412 of the plate 408 may correspond to the positions of the connecting holes 112 of the template 100, and the sleeve structure 400 may be fixed on the periphery P1 by passing through the corresponding connecting holes 112 and through holes 412 through a plurality of fasteners 120. According to an embodiment of the present disclosure, the sleeve structure 400 may be arranged across two templates 100. When the sleeve structure 400 is arranged on the periphery P1 through the plate 408, the hollow body 406 of the sleeve structure extends substantially perpendicular to the ground, and the height of the opening 402 is higher than the plate 408. By means of the sleeve structure 400, a pipe of a guardrail structure may be arranged on the building structure 4000.

FIG10 shows a building structure 5000 according to an embodiment of the present disclosure. The building structure 5000 includes a plane substantially perpendicular to the ground and composed of a plurality of templates 100 for concrete pouring, and a plurality of templates 100', each of which has a first side S1' and a second side S2' opposite to the first side S1', one end of the second side S2' of the templates 100' is disposed on the uppermost periphery P1 of the templates 100, and the templates 100' are perpendicular to the templates 100, so that the first sides S1' of the templates 100' jointly define a plane substantially parallel to the ground and for contacting with concrete, which can be used for pouring a concrete ceiling structure. Like the template 100, the template 100' has a plurality of connection holes 112' on each periphery. According to one embodiment of the present disclosure, the plate 410 of the sleeve structure 400 has a plurality of through holes 412 corresponding to at least two of the connection holes 112' of the templates 100', and the sleeve structure 400 is fixed to the outermost periphery P2 of the templates 100' by passing through the corresponding connection holes 112' and through holes 412'. Here, "outermost" only means that there is no other template against the periphery P2, and does not mean its absolute position. After the sleeve structure 400 is set on the periphery P2 through the plate 410, a pipe of a guardrail structure can be set on the building structure 5000.

By having an L-shaped bottom plate extending beyond the width of the sleeve structure 400, the sleeve structure 400 can be attached to the metal formwork by locking or other suitable means, so that the position of the sleeve structure 400 can be installed at any time as needed to a building structure composed of multiple formworks arranged horizontally or vertically, and can be easily removed from the building structure.
