A kind of installation method of vertical wall panel assembly structure of prefabricated building

Abstract

The installation method of the vertical wall panel assembly structure of the prefabricated building proposed by the present invention includes: S1, producing the upper wall panel and the lower wall panel; S2, after the upper wall panel is demoulded, opening the spiral stirrup from the bottom of the inner bellows Screw in until all the spiral stirrups enter the inner bellows; S3. Transport the upper wall panel and the lower wall panel to the installation site, first hoist the lower wall panel and erect the oblique support, then hoist the upper wall panel to the lower wall panel, The protruding steel bar is aligned with the opening of the inner bellows, and the position is placed so that the protruding steel bar is inserted into the inner bellows, and a diagonal support is erected; S4. Install a formwork around the gap between the upper wall panel and the lower wall panel, and then from the inner bellows Press the grouting material into the upper opening until the grouting material continuously flows out from the gap between the inner bellows and the outer bellows; S5. After the grouting material meets the strength requirements, remove the oblique support and formwork. The installation method of the vertical wall panel assembly structure makes the assembly operation simple, the grouting compactness is reliable, and the vertical connection of the wall panels is more reliable.

Description

technical field [0001] The invention relates to an assembly method of a prefabricated building, in particular to a method for installing a vertical wall panel assembly structure of a prefabricated building. Background technique [0002] In the prior art, the vertical splicing of prefabricated building wall panels is generally connected by grouting sleeves. The protruding steel bars of the lower wall panels are inserted into the pre-buried grouting sleeves in the upper wall panels, and then the connection is completed by grouting. However, during installation , each grouting sleeve in the upper wallboard needs to be aligned with the protruding steel bars above the lower wallboard, so that the upper wallboard can fall smoothly, the operation is quite difficult and the efficiency is low; in addition, the grouting density of the grouting sleeve is very low It is difficult to control and detect, which is also a current industry problem. There is also a vertical connection struct...

[0002] In the prior art, the vertical splicing of prefabricated building wall panels is generally connected by grouting sleeves. The protruding steel bars of the lower wall panels are inserted into the pre-buried grouting sleeves in the upper wall panels, and then the connection is completed by grouting. However, during installation , each grouting sleeve in the upper wallboard needs to be aligned with the protruding steel bars above the lower wallboard, so that the upper wallboard can fall smoothly, the operation is quite difficult and the efficiency is low; in addition, the grouting density of the grouting sleeve is very low Difficult to control and detect, which is also a current industry problem

There is also a vertical connection structure of wall panels, the bellows are pre-embedded at the lower end of the upper wall panel, the upper end of the lower wall panel protrudes from the steel bar, and the protruding steel bar of the lower wall panel is inserted into the bellows tube, and then the connection is completed by grouting. The installation of wall panels is easy, but the connection is unreliable, and it is difficult to find whether the gap between the upper and lower wall panels is filled or empty
