Problems solved by technology

However, there is usually a small gap between the upper prefabricated wall panels and the lower prefabricated wall panels, which is inconvenient to operate.
[0005] In addition, the gap between the upper and lower prefabricated wall panels forms a horizontal joint, which makes the integrity of the upper and lower prefabricated wall panels poor
Moreover, the gap between the upper and lower layers of prefabricated wall panels is treated with mortar, and the strength is lower than that of the concrete of the prefabricated wall panels, which forms a weak point of force and affects the overall earthquake resistance of the building.

Embodiment 1

[0102] Embodiment one: if figure 1 and figure 2 As shown, a prefabricated wallboard is poured according to the actual situation according to the size of the mold to form a wallboard module 1 . The upper and lower end faces of the wallboard module 1 are pre-embedded connecting steel bars 11, and the connecting steel bars 11 extend out of the end of the wallboard module 1 to fix the expanding head 110. Modules 1 are spliced ​​to form wall panels. The size of the expanding head 110 may be the diameter of the expanding head 110 .

[0103] The connecting steel bar 11 can be set through the wall panel module 1 through its entire length. The connecting steel bars 11 can be arranged in one or two layers in the thickness direction, and are regularly arranged in the wall panel module 1 .

[0104] Such as image 3 Shown, connecting reinforcing bar 11 also can not be set in full length, and the pre-embedded part in wall panel module 1 can be straight bar or bent bar, also can connec...

Embodiment 2

[0120] A connection structure of prefabricated wall panels is formed by splicing the prefabricated wall panels in the first embodiment. Such as Figure 18 As shown, the first layer of wall body 2 is built on the foundation in advance, the prefabricated wall panels 21 extend along the horizontal direction, and two adjacent prefabricated wall panels 21 are spliced ​​in a straight line. At the corner position, two adjacent prefabricated wall panels 21 are arranged vertically and spliced ​​in an L-shape to form a corner. When the wall body and the interior wall are spliced, two prefabricated wall panels 21 spliced ​​in a straight line and another prefabricated wall panel 21 are spliced ​​in a T-shaped manner. When dividing the indoor area, the four prefabricated wall panels 21 can be spliced ​​in a cross-shaped manner to divide the space into four parts.

[0121] Here, the connection method of two adjacent prefabricated wall panels 21 is taken as an example for illustration. Su...

Embodiment 3

[0128] A connection structure of prefabricated wall panels is formed by vertical splicing of the prefabricated wall panels 21 in the first embodiment. Such as Figure 27 As shown, the adjacent prefabricated wall panels 21 in the vertical direction are spliced ​​with each other, and the joints of the prefabricated wall panels 21 form a horizontal post-casting belt 24; Offer two mounting holes 31 matching the outer diameter of the connecting steel bar 11 on the 3.

[0129] Such as Figure 28 As shown, when the prefabricated wallboard 21 is provided with a vertical hollow hole 13, the concrete poured in the hollow hole 13 is connected with the horizontal post-casting belt 24 as a whole, thereby further strengthening the connection between the upper and lower layers of the prefabricated wallboard 21.

[0130] Further, as Figure 29 As shown, the vertical direction in the hollow hole 13 is provided with shear reinforcement 25, and one end of the shear reinforcement 25 extends in...

Abstract

The invention relates to a prefabricated wall panel and a connecting structure and a construction method thereof. The prefabricated wall panel comprises a wall panel die block, connecting steel bars are pre-embedded in the upper and lower end surfaces of the wall panel die block, expanded feet are fixed at the ends, extending out of the wall panel die block, of the connecting steel bars, and the sizes of the expanded feet are greater than the outer diameters of the connecting steel bars. The prefabricated wall panels, adjacent to each another in the horizontal direction, of the multiple prefabricated wall panels are spliced to form to be in the shape of a line, T, L or cross, and vertical post-pouring belts are formed at the joints of the prefabricated wall panels. The construction methodcomprises the steps that lower prefabricated wall panels are pre-installed, the lower precast wall panels are installed, supported and located, so that horizontal post-pouring belt space is reserved between the upper and lower prefabricated wall panels; the connecting steel bars of the upper and lower prefabricated wall panels are connected with sleeves; and horizontal post-pouring concrete is poured, so that cement slurry flows into the sleeves. The prefabricated wall panel obtained by the construction method has good connecting integrity and high seismic resistance.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a prefabricated wall panel and its connecting structure and construction method. Background technique [0002] At present, in order to improve the efficiency of building construction, a large number of prefabricated components are usually prepared in advance, and then the prefabricated components are assembled and built to form a prefabricated building. When building a prefabricated wall, the upper and lower end surfaces of the prefabricated prefabricated wall panels are respectively extended with connecting steel bars. After the upper layer of prefabricated wall panels and the lower layer of prefabricated wall panels are aligned, the opposite connecting steel bars are welded to form a prefabricated wall. body. [0003] The Chinese patent whose authorized notification number is CN205369690U discloses a prefabricated building wall panel. The upper end surface and the lower ...
