Description

Fire-proof structure for joint connection joint of light partition hollow slab

Technical Field

The utility model relates to the field of buildings, in particular to a fire-proof structure for a joint connection node of a light partition hollow slab.

Background

The light partition board is a new energy-saving wall material, it is a wall material whose exterior is like hollow floor, but its two sides have male and female tenon grooves, and when it is mounted, it only needs to stand up the board, and after the male and female tenon are coated with a small quantity of caulking mortar, they can be assembled. The light partition board has the advantages of light weight, high strength, multiple environmental protection, heat preservation, heat insulation, sound insulation, breathing, humidity regulation, fire prevention, rapid construction, wall cost reduction and the like. The connection node of the light partition wall is one of weak links, and particularly, fireproof protection is often a security measure with little attention, and once problems occur, the deformation is serious, so that the subsequent repair cost is increased.

Disclosure of Invention

Aiming at the defects and shortcomings of the prior art, the utility model provides a fire-proof structure for the joint connection joint of the hollow slab of the light partition wall, which solves the problems that the connection joint of the light partition wall is one of weak links, particularly fire protection is often a safety measure with little attention, deformation is serious once the problem occurs, and the subsequent repair cost is increased.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a fire-proof structure for joint connection joints of light partition hollow plates comprises partition plates, purlines, side columns, heat-insulating layers and joint belts; the partition boards are of light wall plate structures, waterproof paint layers are paved on one surface of the partition boards facing outdoors, purlines are fixedly connected between the partition boards, and the partition boards on two sides of the wall are connected into a whole through the purlines; the middle part of the partition plate is provided with a seam, reinforced concrete column structures are built in the partition plate cavities at two sides of the seam to serve as side columns, and heat preservation layers are filled in the cavities outside the side columns between the partition plates; joint belts are paved outside the partition boards at two sides of the joint, the joint belts cover joints of the partition boards, and the joint belts are fixedly connected with pre-buried U-shaped steel in the side columns through steel nails; and a seam gap in the seam tape is filled with a rock wool filling layer.

Preferably, the joint belt extends to the partition boards at two sides of the joint by not less than 100mm, the width of the U-shaped steel connected and fixed with the joint belt is not less than 300mm, and the interval between the U-shaped steel is not more than 1000mm.

Preferably, the rock wool filling layer is filled with gypsum putty to one side in the joint, and a layer of putty is scraped between the outside of the rock wool filling layer and the waterproof coating layer.

The beneficial effects of the utility model are as follows: the structure forms good fireproof protection measures through the joint belts and the rock wool filling layers, simultaneously enhances the shearing resistance and the loading capacity of the connecting nodes, effectively enhances the structural strength of the light partition wall, and does not influence the heat preservation and water resistance.
