Problems solved by technology

By filling the top member and compressible solids in the mid-span of the splicing joint between the top of the filling wall and the beam or slab, the sound insulation performance of the partition wall is improved, and the displacement and deformation of the filling wall are effectively restrained. It is more convenient for construction to squeeze and compact the slurry embedded in the splicing joint, so as to avoid the problem of cracking caused by the non-extruded and dense slurry of the splicing joint

Embodiment 1

[0028] see figure 1 A method for sealing the joint between the filled wall and the beam slab provided in this embodiment includes the following steps:

[0029] 1) In advance, drive the jacking fixture 4 into the seam 3 between the top of the infill wall 1 and the beam or slab (beam slab 2), and fix the position between the infill wall 1 and the beam or slab to constrain the filling Displacement of the wall; wherein, the top member 4 is a wedge-shaped stone, wood or brick, and one is set at every 100-300mm interval along the 3 joints.

[0030] 2) Insert filler 5 at the mid-span position of splicing seam 3, and reserve grooves 6 on both sides of splicing seam 3; wherein, said filler 5 is a compressible solid material, and said compressible The solid material is PU foam caulk.

[0031] 3) Fill the grooves 6 on both sides of the splicing joint 3 tightly with mortar 7; wherein, the mortar 7 is a building mortar that has water retention and does not need to be used for moisturizin...

Embodiment 2

[0034] see figure 2 , this embodiment is basically the same as Embodiment 1, the difference is that there is a vacancy 8 in the top middle of the filling wall 1, and the filler 5 can at least plug the vacancy 8.

Abstract

The invention discloses a method for fixedly sealing a seam between an infill wall and a beam or a board. The method is characterized by including the following steps that firstly, a jacking piece is inserted in the seam between the top of the infill wall and the beam or the board in advance, the position between the infill wall and the beam or the board is jacked and fixed, and the displacement of the infill wall is restrained; secondly, filler is inserted in the middle of the span of the seam and grooves are reserved in the two sides of the seam; thirdly, the grooves in the two sides of the seam are filled with mortar compactly. The invention further discloses a structure for fixedly sealing the seam between the infill wall and the beam or the board to implement the method. By the adoption of the method and structure, the middle portion of the span of the seam between the top of the infill wall and the beam or the board is filled with the jacking piece and compressible solid, namely the filler, the sound insulation performance of a partition is improved, displacement and deformation of the infill wall are effectively restrained, construction can be conducted so as to squeeze and compact mortar in the seam conveniently, and the problem that the mortar of the seam cracks due to the fact that the mortar is not squeezed compactly is solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method and structure for solidly sealing the joint between a filling wall and a beam slab. Background technique [0002] At present, there are often cracks in the splicing seams between the filling walls of houses and beams or slabs, especially for walls assembled from concrete wall panels. After investigation and research, it is found that there are many reasons for the cracks between the top of the building filling wall and the beam or slab, and the most common problem is that the cracks filled in the joint between the top of the filling wall and the beam or slab The shrinkage value of the slurry doubles and cracks. The reason for the doubling of the shrinkage value of the slurry is mainly related to the fact that the slurry stuffed into the splicing joint is not compacted. Because on the one hand, the seam between the infill wall and the beam slab is relative...
