Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically to a prefabricated building. Background Technology
[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.
[0003] In the practical application of prefabricated building projects, considering the overall structural stability and reliability of the building, the prefabrication and assembly of building structural support columns and beams are rarely carried out. Most of them are still constructed by on-site casting, which is less efficient and affects the construction progress.

[0033] See Figure 1 As shown, a prefabricated building according to this embodiment includes:
[0034] The precast column component 100 includes a concrete column, connecting screws (101A, 101B) and connecting hole components 102. One end of the connecting screws (101A, 101B) is embedded in the first end of the concrete column, and the other end extends out of the concrete column from the first end. The connecting hole components 102 are embedded in the second end of the concrete column. The second end and the first end are the opposite ends of the concrete column.
[0035] The precast beam component 200 includes a concrete beam body, one end of which has a beam-column connection grouting hole (202, 203);
[0036] The connecting screws (101A, 101B) of the lower precast column component 100 pass sequentially through the beam-column connection grouting holes (202, 203) of the precast beam component 200 and the connecting hole component 102 of the upper precast column component 100. The connecting screws (101A, 101B) of the lower precast column component 100 are fixedly connected to the connecting hole component 102 of the upper precast column component 100 by tightening nuts.
[0037] This embodiment of a prefabricated building involves manufacturing prefabricated column components 100 and prefabricated beam components 200 in a factory, transporting the prefabricated components to the construction site, and then using hoisting for assembly and fixing. The connecting bolts (101A, 101B) of the lower prefabricated column component 100 pass sequentially through the beam-column connection grouting holes (202, 203) of the prefabricated beam component 200 and the connecting hole component 102 of the upper prefabricated column component 100, and are then tightened with fastening nuts. This achieves one-time installation of beam-column joints and column-column joints, making the installation process simple and convenient, greatly improving construction efficiency. After installation, the beam-column joints and column-column joints are stable and reliable, meeting the requirements for prefabricated building construction.
[0038] Furthermore, in this embodiment, one end of the concrete beam has a beam-column connection lug 201, and the beam-column connection lug 201 has a first beam-column connection grouting hole 202 that runs vertically through the beam.

[0039] The precast beam component in this embodiment has a beam-column connection lug 201, so that a beam-column node can realize the simultaneous fixed assembly of a precast column component and two or more precast beam components at one time, which greatly improves the assembly efficiency and ensures the stability and reliability of the main beam connection node.
[0040] Furthermore, in this embodiment, the concrete beam has a second beam-column connection grouting hole 203 that extends vertically through the beam. The connecting bolts include a second connecting bolt 101B and a third connecting bolt (not shown).

The other end of the mounting screw 1000 passes through the mounting plate connection channel 301 and the embedded steel plate 302 and is fixedly connected to the embedded steel plate 302 of the exterior wall panel 300 by a fastening nut 900.
[0043] Furthermore, steel washers 800 are respectively provided between the fastening nut 900 and the concrete beam of the precast beam component 200, and between the fastening nut 900 and the embedded steel plate 302 of the exterior wall panel 300.
[0044] See Figure 4 As shown, in this embodiment, a sealing strip 600 is provided in the gap between the exterior wall panel 300 and the precast column component 100 to achieve the sealing of the gap between the exterior wall panel 300 and the precast column component 100.
[0045] Specifically, the sealing strip 600 in this embodiment is an EPDM sealing strip.
[0046] Furthermore, in this embodiment, PE rods 400 are respectively installed on both sides of the sealing strip 600 in the gap between the exterior wall panel 300 and the precast column component 100. The gap on one side of the PE rod 400 is sealed with filling mortar 700, and the gap on the other side of the PE rod 400 is sealed with building weather-resistant structural adhesive 500. See Figure 6 As shown, in this embodiment, a sealing strip 600 is installed in the gap between the exterior wall panel 300 and the precast beam component 100 below, and the gap is sealed on both sides of the sealing strip 600 by filling mortar 700.
[0047] Specifically, the sealing strip 600 in this embodiment is an EPDM sealing strip.

It also realizes the installation of the exterior wall panel 300 and the sealed connection between the exterior wall panel 300 and the prefabricated column components 100 and prefabricated beam components 200. This provides a brand-new assembly method for the basic structural units of prefabricated buildings, resulting in better overall structural stability and reliability, and improved construction efficiency.
