Detailed Description
The technical scheme of the utility model is described in detail below with reference to the accompanying drawings and examples.
In this embodiment, the hollow pier is taken as an example to describe the technical scheme of the utility model, but it is understood that the utility model is also applicable to other concrete facilities with hollow structures.
Fig. 1 shows a schematic diagram of a cross section of a hollow pier forming system provided by an embodiment of the present utility model, referring to fig. 1, a plurality of outer formworks 10 are spliced with each other according to the outline of the outer boundary of the hollow pier to form a waist-shaped outer mold, a plurality of inner formworks 20 are spliced with each other according to the outline of the inner boundary of the hollow pier to form a waist-shaped inner mold, the inner mold is located at the inner side of the outer mold, a plurality of pull rods 30 extending in the inner and outer directions are arranged between the inner mold and the outer mold, a forming cavity is formed between the inner mold and the outer mold, and during casting, concrete is injected into the forming cavity to form the hollow pier after solidification. The outer shapes of the inner mold and the outer mold are not limited herein, and may be circle center, ellipse, polygon, etc. in addition to the oval shape in fig. 1.
After pouring is completed, the concrete will apply an external load to the inner and outer molds, which, for the outer mold, will force two outer mold plates 10 adjacent in the horizontal direction away from each other due to the outward direction, so that the outer mold will not be affected when the outer mold is removed; however, for the inner mold, the external load is directed inward, so that two inner forms 20 adjacent in the horizontal direction are forced to be pressed close, and thus it is difficult to remove the inner forms 20, and there is a high possibility that the structure of the inner forms 20 is damaged during the removal.
In order to solve the problems, the embodiment of the utility model provides a hollow pier inner template connecting device, so that the inner template can be conveniently removed after pouring is completed.
Fig. 2 shows a schematic view of a hollow pier inner form connecting device according to an embodiment of the present utility model, referring to fig. 2, at least two adjacent inner forms 20 are not in direct contact in the horizontal direction, for example, two adjacent inner forms 20 are respectively named as a first inner form 21 and a second inner form 22 in fig. 2, a spacing area 20a exists between the first inner form 21 and the second inner form 22 in the horizontal direction (left-right direction in fig. 2), specifically, the right side edge of the first inner form 21 is not in contact with the left side edge of the second inner form 22, so that a gap, that is, a spacing area 20a, is formed between the opposite two side edges. In the space region 20a, there is provided a connecting mechanism 40 for connecting the first inner die plate 21 and the second inner die plate 22 together, the outer side of the connecting mechanism 40 closing the outer end of the space region 20a so that the outer surface of the inner die is kept continuous in the circumferential direction, and outflow from the space region 20a is avoided when concrete is poured, and in addition, the connecting mechanism 40 is not in contact with the side edges of the first inner die plate 21 and the second inner die plate 22, so that when an external load from concrete is applied after pouring, the opposite edges of the first inner die plate 21 and the second inner die plate 22 can be displaced to the position where the space region 20a is located by a small amount, and thus can not be pressed against each other as in the prior art, and therefore, when the connecting mechanism 40 is removed, the first inner die plate 21 and the second inner die plate 22 can be removed relatively easily only by removing the connecting mechanism 40 first.
The connecting mechanism 40 has a locked state and an unlocked state, wherein the locked state is shown in fig. 2, and it can be found that the connecting mechanism 40 is provided in the spacing region 20a in a penetrating manner in the inner and outer direction (up and down direction in fig. 2, above outside, below inside), and is abutted inward from the outside against the outer surfaces of the first inner die plate 21 and the second inner die plate 22, and is abutted outward from the inside against the inner surfaces of the first inner die plate 21 and the second inner die plate 22, that is, the connecting mechanism 40 clamps the first inner die plate 21 and the second inner die plate 22 against each other in the inner and outer directions from the inner and outer opposite directions, preventing the first inner die plate 21 and the second inner die plate 22 from being displaced in the inner and outer directions. It will be appreciated that in the unlocked state, the outside and inside of the connection mechanism 40 are separated from the outer and inner surfaces of the first and second inner templates 21 and 22, respectively, so that the first and second inner templates 21 and 22 can be separated from the connection mechanism 40, i.e., unlocked.
In this embodiment, the connection mechanism 40 includes a first connection member 41, a second connection member 42, and a locking assembly 43.
The first connecting member 41 is at least partially located at the outer sides of the first and second inner templates 21 and 22, specifically, the left and right ends of the first connecting member 41 are at least located at the outer sides of the first and second inner templates 21 and 22, and the left and right ends overlap at least partially with the outer surfaces of the first and second inner templates 21 and 22, respectively, in the horizontal direction, so that the first connecting member 41 is abutted against the outer surfaces of the first and second inner templates 21 and 22 in the locked state. In the height direction, the first connector 41 needs to be flush with the height of the spacing region 20a to ensure that the first connector 41 can completely close the outside of the spacing region 20a, avoiding that concrete flows into the inside of the spacing region 20a when casting.
The second connecting member 42 is at least partially located inside the first and second inner templates 21 and 22 corresponding to the first connecting member 41, specifically, left and right ends of the second connecting member 42 are at least located outside the first and second inner templates 21 and 22, and left and right ends overlap at least partially with inner surfaces of the first and second inner templates 21 and 22, respectively, in a horizontal direction, so that the first connecting member 41 is abutted against the inner surfaces of the first and second inner templates 21 and 22 in a locked state.
A locking assembly 43 is disposed in the space region 20a between the first and second connection members 41 and 43, and the locking assembly 43 is used to adjust the inner and outer distances between the first and second connection members 41 and 42, thereby locking and unlocking the first and second inner templates 21 and 22.
The length and the area of the partial overlapping between the first connecting member 41 and the second connecting member 42 and the surface of the inner mold plate may be adjusted according to actual needs, and it is only necessary to ensure that the connecting mechanism 40 can lock the first inner mold plate 21 and the second inner mold plate 22 relatively. The number of the second connecting members 42 may be one as in the case of the first connecting members 41, or may be divided into a plurality of independent units. In addition, since the first and second inner templates 21 and 22 generally have a large height, in order to secure the stability of the connection of the first and second connection members 41 and 42 throughout in the height direction, the locking assembly 43 may be provided in plurality along the height direction.
In this embodiment, the outer end of the locking component 43 passes through the second connecting piece 42 to be clamped on the first connecting piece 41, the inner end of the locking component 43 is adjustably fixed with the second connecting piece 42, and the locking and unlocking of the first inner die plate 21 and the second inner die plate 22 are controlled by the inner end of the locking component 43. Wherein adjustable fixation means: the inner end of the locking assembly 43 may be fixed relative to the first connecting member 42 or movable relative to the first connecting member 42, and the first connecting member 41 and the second connecting member 42 lock the first inner die plate 21 and the second inner die plate 22 when the inner end of the locking assembly 43 is fixed relative to the second connecting member 42; when the inner end of the locking assembly 43 is moved relative to the second connector 42, the first and second connectors 41 and 42 unlock the first and second inner templates 21 and 22.
Specifically, as shown in fig. 3, in this embodiment, the locking assembly 43 includes a locking rod 431 and a locking sleeve 432, where an outer end of the locking rod 431 passes through the second connecting member 42 to be clamped with the first connecting member 41, an inner end of the locking rod 431 at least partially protrudes from an inner surface of the second connecting member 42, and the locking sleeve 432 is connected to an outer periphery of an inner end of the locking rod 431 by threads, so that only the locking sleeve 432 needs to be screwed to adjust an axial position of the locking sleeve 432 on the locking rod 431, and further, an inner-outer distance between the first inner template 21 and the second inner template 22 is controlled, that is, the first inner template 21 and the second inner template 22 are locked and unlocked. For example, only the locking sleeve 432 needs to be screwed outwards, the outer end of the locking sleeve 432 is abutted against the inner surface of the second connecting piece 42, so that the second connecting piece 42 is driven to move towards the first connecting piece 41, the distance between the first connecting piece 41 and the second connecting piece 42 is reduced, and locking between the first inner die plate 21 and the second inner die plate 22 is achieved; instead, only the locking sleeve 432 is screwed inward, the outer end of the locking sleeve 432 is spaced apart from the inner surfaces of the second connecting members 42, and thus the second connecting members 42 are separated from the inner surfaces of the first and second inner templates 21 and 22, i.e., the distance between the first and second connecting members 41 and 42 is increased, thereby unlocking the first and second inner templates 21 and 22.
As shown in fig. 3, in this embodiment, the locking assembly 43 further includes a gasket 433 sleeved on the outer periphery of the locking rod 431 and located inside the locking sleeve 432, and when locking, the gasket 433 abuts against the inner surface of the second connecting member 42 to increase the stress area, so as to prevent the screw thread from loosening.
In one embodiment, the locking assembly 43 may include only the locking lever 431 without the locking sleeve 432, in which case the outer end of the locking lever 431 still is engaged with the first connecting member 41, but the inner end of the locking lever 431 is directly screwed with the second connecting member 42, in which case, after the locking lever 431 is mounted between the first connecting member 41 and the second connecting member 42, only the second connecting member 42 needs to be continuously rotated on the locking lever 431, so that the second connecting member 42 moves toward the direction of the first connecting member 41, thereby reducing the distance between the second connecting member and the first connecting member 41, and locking between the first inner mold plate 21 and the second inner mold plate 22 is achieved. When unlocking is needed, the second connecting piece 42 can be moved inwards from the locking rod 431 only by reversely rotating the second connecting piece 42, and then the second connecting piece 42 is separated from the inner surface of the inner template, so that unlocking is realized.
In this embodiment, as shown in fig. 4 and 5, the first connecting member 41 includes a connecting hole 410, and a hook 4311 (see fig. 3) is disposed at an outer end of the locking lever 431, and the hook 4311 extends into the connecting hole 410 to implement the locking of the locking lever 431 with the first connecting member 41. Specifically, in the present embodiment, the first connector 41 includes an extending portion 411 extending inward, so that the first connector 41 is generally represented as "T" in fig. 2, the connecting hole is provided on the extending portion 411, and the hook portion 4311 protrudes into the connecting hole 410. Further, in the present embodiment, the connecting hole 410 is a through hole, that is, the connecting hole 410 penetrates through two opposite sides of the extension portion 411, and the hook portion 4311 extends from one side of the extension portion 411 to the other side, so as to improve the fastening stability and prevent the hook portion 4311 from being easily separated from the connecting hole. In addition, the bending angle of the hook 4311 can be reasonably arranged, so that the stability of the clamping connection is further improved.
It should be noted that, instead of the extension portion 411, the first connector 41 may be provided with a connection hole penetrating in the inner and outer directions, where the connection hole needs to have a dimension larger than the outer shape of the hook portion 4311 at least in one direction (for example, in the horizontal direction) to ensure that the hook portion 4311 can pass through the connection hole, and then the locking lever 431 is rotated in a certain direction (for example, above) so that the position of the hook portion 4311 rotates relative to the connection hole, and the hook portion 4311 abuts against the outer surface of the first connector 41, so that the locking between the locking lever 431 and the first connector 41 can be achieved.
As shown in fig. 6, the second connecting member 42 of this embodiment is a channel steel, and has a U-shaped cross section, and a through hole penetrating through the inner and outer surfaces is provided in the middle for the locking rod 431 to pass through.
As shown in fig. 2, a supporting body 50 is further provided in the interval region 20a, the left and right sides of the supporting body 50 are not in contact with the first and second inner templates 21 and 22, the connection mechanism 40 is penetrated in the supporting body 50 in the inner and outer directions, and the supporting body 50 supports the connection mechanism 40 so as to facilitate the installation of the connection mechanism 40. Specifically, the supporting body 50 may be square lumber which is often used in the construction field.
