DETAILED DESCRIPTION

[0049] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0050] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be understood as the usual meanings understood by the skilled in the art to which the present application belongs.

[0051] As Figure 1As shown, the embodiment of the present application provides a prefabricated building structure plate component 100, which comprises a structure plate main body 110 and a polygonal component 120 fixedly arranged at the side end of the structure plate main body 110. The polygonal component 120 is located at the side of the two plate surfaces of the structure plate main body 110 and the side away from the side end of the structure plate main body 110 to form a corner 121. The polygonal component 120 is located between the side end of the structure plate main body 110 and the corner 121 on the two plate surfaces, and between the corner 121 on the two plate surfaces and the corner 121 on the side away from the structure plate main body 110 to form a connecting edge 122. Each corner 121 is provided with a recessed part 123. When two structure plate components 100 are spliced, any corner 121 of the polygonal component 120 of one structure plate component 100 abuts against any corner 121 of the polygonal component 120 of another structure plate component 100, and the two sides of the two abutting corners 121 form a V-shaped included angle 200 for mounting a connecting piece. The recessed parts 123 between the two abutting corners 121 form a cavity for mounting a sealing strip 500.

[0052] The structure plate component 100 of the present application adopts the structure of arranging the polygonal component 120 at the side end of the structure plate main body 110, which can be prefabricated integrally in the factory. When assembled, the polygonal components 120 of the structure plate components 100 are connected by bolts 420 to form a building as a whole. The polygonal component 120 can directly serve as a beam column of the building. Therefore, it is not necessary to first assemble a prefabricated beam column to build a framework, which reduces the difficulty of assembly and improves the efficiency of assembly, and at the same time, meets the strength requirements of the building.

[0053] The structure plate components 100 are connected by the abutting mode of the corners 121 of the polygonal components 120. After connection, the two sides of the two abutting corners 121 can form a V-shaped included angle 200. When fixed, the connecting piece can be fixedly connected by obliquely punching the bolt 420 in the V-shaped included angle 200. The fastening construction angle is open and easy to use a general electric wrench to tighten, which is convenient to operate. After tightening, the bolt 420 does not protrude from the wall surface, and the appearance is beautiful.

[0054] The structure plate components 100 are connected by the abutting mode of the corners 121 of the polygonal components 120. At the same time, the recessed parts 123 are arranged at the corners 121 of the polygonal components 120 of the structure plate components 100. When two structure plate components 100 are spliced, the sealing strip 500 can be mounted between the recessed parts 123 of the two abutting corners 121. In this way, the sealing property of the splicing of the two structure plate components 100 can be improved, and the water stopping effect of assembly can be improved.

[0055] In some embodiments, the polygonal component 120 adopts a hollow tubular structure, which is filled with rubber, so as to strengthen the anti-seismic and energy absorption effect.

[0062] Optionally, the two side surfaces of the structural plate body 110 are substantially flush with the side angles 121 on the two sides of the polygonal component 120, so that there is no protruding part on the two sides of the two structural plate components 100 after assembly, and the two sides of the side end of the structural plate body 110 are provided with inclined surfaces to provide sufficient space for the installation of the V-shaped angle plate 410.

[0074] The connecting piece includes a V-shaped angle plate 410 and a three-edge connecting piece 430.

[0075] The two side plates of each V-shaped angle plate 410 are respectively fixed on the connecting edges 122 on both sides of the V-shaped clamping angle 200 by bolts 420.

[0076] The U-shaped clamping groove 300 is provided with a three-edge connecting piece 430, and the three-edge connecting piece 430 is respectively fixedly connected with the three structural plate members 100.

[0077] In the above manner, the four structural plate members 100 can be assembled into a cross-shaped structure.

[0079] In some embodiments, referring to Figures 13-15 , the three-edge connecting piece 430 includes a U-shaped connecting piece 433, and the three side plates of the U-shaped connecting piece 433 are respectively fixedly connected with the connecting edges 122 of the three structural plate members 100 around the U-shaped clamping groove 300 by bolts 420.

[0080] When the above three-edge connecting piece 430 is used to connect the adjacent three structural plate members 100, the U-shaped connecting piece 433 can be installed in the U-shaped clamping groove 300 formed by the three structural plate members 100, and then the bolts 420 are screwed into the corresponding three connecting edges 122 of the three structural plate members 100 from the three side plates of the U-shaped connecting piece 433, which has a relatively simple structure, but the connection strength is not very high, and the operation is relatively troublesome, especially when the bolts on both sides of the U-shaped connecting piece 433 are screwed in a narrow space.

[0081] In some embodiments, referring to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 and Figure 12 , the three-edge connecting piece 430 includes two clamping pieces 431 and a locking block 432.

[0082] The recess 123 of each corner 121 of the polygonal member 120 of the structural slab member 100 adopts a narrowed locking groove, two clamping plates 431 are arranged on both sides of the U-shaped clamping groove 300, one end of each clamping plate 431 is provided with a locking head 4311 clamped in a locking groove outside the U-shaped clamping groove 300, and the other end of the clamping plate 431 extends into the U-shaped clamping groove 300 and is provided with a trapezoidal clamping block 4312 with a wide inner end and a narrow outer end.

[0085] In summary, the structural slab member 100 with the polygonal member 120 arranged at the end of the structural slab body 110 in the embodiment is used to assemble the common straight line structure, L-shaped structure, T-shaped structure and cross-shaped structure of the fabricated building, the structural slab member 100 can be mass-produced in the factory, the beam and column are included in the structural slab member 100 out of the factory, and the equivalent strength is realized through combination and connection. Through integrated design, the precast beam and column do not need to be assembled to build the framework during assembly, which reduces the assembly difficulty and improves the assembly efficiency, and at the same time, the strength requirement of the building can be met.

[0086] The above-mentioned design is suitable for mass production and on-site installation, and can realize fast installation by screwing, which is easy to cooperate with workers to realize assembly, and realizes the transformation from traditional building workers to fabricated building workers.

[0087] In the assembling of the embodiment, the structure plate members 100 are abutted by the edges 121 of the polygonal members 120, and the edges 121 of the polygonal members 120 are provided with recesses 123, so that the sealing strips 500 can be installed between the recesses 123 of the abutted edges 121, thereby improving the sealing of the structure plate members 100 and the water stopping effect of the assembly.
