Description

Prefabricated anti-cracking frame vertical plate for slat inner partition wall hole structure

Technical Field

The utility model belongs to interior partition hole structure field especially relates to kind and is used for the prefabricated frame riser of preventing ftractureing of partition hole structure in the slat.

Background

When the inner partition wall batten is installed, holes are of important nodes, the head board of the existing inner partition wall batten is spliced at the inner corner position of holes in holes, and due to frequent opening and closing of , the transverse and vertical spliced joints of the inner corner at the upper part of holes are easy to crack, so that special construction treatment is needed when holes are installed and built, and according to market investigation, the problem that the holes crack is solved by the following scheme in the existing construction operation.

The scheme includes that rabbets are processed on existing light inner partition wall battens to form frame vertical plates, corresponding lengths are cut on the existing light inner partition wall battens to form head plates, two ends of 2 head plates are lapped on the rabbets of 4 frame vertical plates to form holes, the field-cut 6 head plates and frame vertical plates have larger geometric size deviation compared with a factory prefabricated product and are poor in mutual matching, and accordingly splicing gaps are uneven in size, splicing faces of frame vertical plates and head plates are bonded through joint mortar, due to the fact that the splicing gaps are uneven in size, the thickness of the joint mortar in the joints is not , bonding firmness of hole splicing positions cannot be guaranteed, after users use 633 of the built holes holes for the period, frequent opening and closing vibration of are found, a plurality of cracks occur at the splicing positions of inner corners of head plates, the joint positions of head plates are found, the joint faces of 686 are not prone to crack, the joint faces are required after splicing is finished, the joint of steps, the joint faces are subjected to be spliced, the joint faces are subjected to high in construction period, the joint construction period of the joint is increased, the joint of , the joint is increased, the joint face leveling mortar, the joint is increased, the joint of the joint, the joint is increased, the joint of the joint face construction cost of is increased, and the joint is increased.

The second scheme is that holes are cast in situ and holes are built in situ, and the cast-in-situ and the built in-situ belong to old wet-process operation, so that the construction waste is large, the cost is high, and the construction period is long.

Meanwhile, the operation modes of cutting, processing and building holes on site, pouring holes on site and building holes on site are large in dust and garbage pollution, and the assembly type green building guide is not met.

Therefore, the utility model provides kinds of problems that hole splicing part cracks because of frequent opening and closing vibration of the current hole structure are solved.
