Description

Precast reinforced concrete beam-column structure

The present invention relates to a precast reinforced concrete beam-column structure, and in particular to a precast reinforced concrete beam-column structure used in a precast construction method.

Precast construction is a construction method that manufactures building elements in factories or manufacturing sites and then transports them to the site for assembly. This method has many advantages, including: the quality of precast building elements is easy to control, and the construction time is greatly shortened, saving the time and manpower required for on-site construction.

However, in the existing precast construction method, although building elements such as floors, walls, beams, or columns can be pre-fabricated in the factory, the combination of different building elements usually requires special joint components to be joined, or special methods are required. As a result, the assembly of precast building elements requires the use of expensive special joints and requires highly skilled manpower.

Due to the above reasons, the existing precast construction method still has room for improvement. Therefore, how to overcome the above defects through the improvement of structural design has become one of the important issues that the industry wants to solve.

In order to solve the above technical problems, the present invention also provides a manufacturing method for manufacturing the precast reinforced concrete beam-column structure.

One of the beneficial effects of the present invention is that the precast beam column structure provided by the present invention can pre-install the precast reinforced concrete beam column structure with the connection assembly that can be quickly fixed and installed, thereby simplifying the construction and installation procedures of the precast beam column and simplifying the structure of the connection assembly, thereby achieving the purpose of reducing costs.

[First embodiment]

Referring to Figures 1 to 5, the first embodiment of the present invention provides a "precast reinforced concrete beam column structure". In order to more conveniently introduce the technology of the present invention, the following will first introduce the precast reinforced concrete beam column structure 1, and then introduce the manufacturing method of the precast reinforced concrete beam column structure 1.

As shown in Figures 1 and 2, the precast reinforced concrete beam column structure 1 of the first embodiment of the present invention includes: a beam column skeleton 100, a concrete sheath 200, and at least one connection assembly 300.

For the sake of convenience, a longitudinal direction can be defined, and the beam frame 100 includes a plurality of steel bars 110 substantially parallel to the longitudinal direction, and stirrups 120 tied to the plurality of steel bars 110 substantially perpendicular to the longitudinal direction. The concrete sheath 200 is formed by a cement mortar mixture being coated on the outer sides of the plurality of steel bars 110 and stirrups 120 of the beam frame 100 by pouring molding. The beam frame 100 and the concrete sheath 200 are combined to form a columnar structure with good compressive strength, tensile strength, and shear strength, so that the precast reinforced concrete beam-column structure 1 of the present invention can be used to be set at the beam or column position of the building and serve as the load-bearing structure of the building.

The precast reinforced concrete beam column structure 1 has at least one connection assembly 300 disposed at one or both ends of the precast reinforced concrete beam column structure 1 in the longitudinal direction. Each connection assembly 300 includes: a first substrate 310, a second substrate 330, and a steel structure connection member 320 connected between the first substrate 310 and the second substrate 330.

In this embodiment, the first substrate 310 is a plate cut from a steel plate material. The first substrate 310 has a top surface and a side surface opposite to each other. One end of the plurality of steel bars 110 of the beam frame 100 facing the connection assembly 300 is connected to the top surface of the first substrate 310. The second substrate 330 is substantially parallel to the first substrate 310 and is spaced apart from the first substrate 310. The steel structure connector 320 is welded between the first substrate 310 and the second substrate 330, so that the first substrate 310 and the second substrate 330 are connected together with a spacing between each other.

In this embodiment, a plurality of steel bars 110 are connected to the top surface of the first substrate 310 by welding, and the concrete sheath 200 abuts against the top surface of the first substrate 310, thereby combining the connection assembly 300, the column frame 100 and the concrete sheath 200.

The steel connector 320 is connected between the first substrate 310 and the second substrate 330 by welding. The steel connector 320 is composed of a plurality of steel plates 321 substantially parallel to the longitudinal direction. The steel connector 320 has a uniform cross-sectional shape along the longitudinal direction, and at least two of the steel plates 321 are perpendicular to each other to improve the cross-sectional modulus of the steel connector 320. For example, in this embodiment, the steel connector 320 is composed of two mutually perpendicular steel plates 321 to form a cross-shaped cross-section structure, so that the steel connector 320 has good anti-bending ability.

It is worth noting that, in this embodiment, although the steel structure connector 320 is a structure with a cross-shaped cross section composed of two mutually perpendicular steel structure plates 321, the present invention is not limited thereto. For example, in embodiments not shown in other figures of the present invention, the steel structure connector 320 can also be a structure with other cross-sectional shapes, for example: the steel structure connector 320 can be a steel section with an H-shaped cross-sectional shape, or a steel structure with other cross-sectional shapes.

The second substrate 330 is connected to a side of the steel connecting member 320 opposite to the first substrate 310 . In this embodiment, the second substrate 330 is a plate body cut from a steel plate. The second substrate 330 can be attached to a predetermined installation position 400 of the precast reinforced concrete beam column structure 1 on one side relative to the beam frame 100, and a plurality of through holes 331 are provided on the second substrate 330. The positions and diameters of the plurality of through holes 331 match the plurality of bolts 410 provided on the installation position 400, so that the plurality of through holes 331 can be sleeved on the plurality of bolts 410 on the corresponding installation position 400, and the second substrate 330 is fixed to the installation position 400 through a plurality of nuts 420, so that one end of the precast reinforced concrete beam column structure 1 corresponding to the connecting assembly 300 can be fixedly connected to the installation position 400.

The precast reinforced concrete beam column structure 1 of the present invention can be used as a column of a building structure, and can also be used as a beam of a building. The second base plate 330 of the connection assembly 300 of the precast reinforced concrete beam column structure 1 is flat on one side of the installation position 400, so the installation position 400 only needs to provide a flat surface that matches the second base plate 330, and a plurality of bolts 410 are pre-set, so that the connection assembly 300 can be fixedly installed at the installation position 400, so that the precast reinforced concrete beam column structure 1 of the present invention can be quickly assembled, and does not need to set a complex shape of the connection joint, so as to simplify the assembly process of the precast beam column and reduce the cost.

In addition, both ends of the concrete casting mold 500 have notches capable of accommodating the connection assembly 300. Then, the connected beam frame 100 and the connection assembly 300 are placed in the concrete casting mold 500. The operator then pours cement mortar into the forming space 510 of the concrete casting mold 500 to cover the beam frame 100.
