Description

Seam assembly and building structure

[ field of technology ]

The utility model relates to the technical field of assembled buildings, in particular to a joint assembly and a building structure.

[ background Art ]

At present, after the box body is hoisted, the box bodies of the concrete modularized integrated building are spliced. And concrete modularization is widely applied to the field of construction. If the building is subjected to rainy days or floor water leakage, water can infiltrate through the splicing seams.

In the traditional processing mode aiming at the joint, main joint filling and water prevention are usually carried out after a polyethylene foam rod and cement mortar are mixed, but as the polyethylene foam rod is used as a foam material and is provided with pores, the polyethylene foam rod is easy to absorb water in the cement mortar after a period of time, and the deformation and the adhesive force of the material are weakened after water absorption, so that the cement mortar leaks through the polyethylene foam rod; in addition, in the cement mortar pouring process, the polyethylene foam rod falls into the gap easily due to insufficient bearing, so that the gap appears, and the water seepage problem appears in the gap, so that the service life of the concrete module is greatly shortened. And the infiltration phenomenon appears when water enters into the gap inside and can make concrete block's life shorten by a wide margin, seriously influences resident's living safety.

7. The technical problem to be solved by the utility model is to provide a building structure which has the same beneficial effects as the earphone device and is not described in detail herein.

8. The opening of the utility model comprises an inner wall opening and an outer wall opening, the joint component can be arranged in the gap corresponding to the inner wall opening and/or the outer wall opening, and the sealing component is correspondingly arranged between the inner wall opening and/or the outer wall opening and the joint component. The seam structure can be arranged in a targeted manner to protect the outer wall or the inner wall.

9. The sealing assembly comprises a sealing layer and a slurry layer, wherein the sealing layer is arranged in a gap, one side of the sealing layer is connected with one end of a mounting piece close to an opening, and the other side of the sealing layer is connected with the slurry layer. The cement component in the slurry can react with the surface of the building unit in the gap to form a cementing interface with strong adhesive force, so that the adhesive force and durability of the slurry layer are improved.

10. The end of the sealing layer far away from the slurry layer and the receiving piece are provided with a containing space, so that the capacity of the waterproof cavity 24 is improved, and the waterproof performance of the building structure 100 is improved.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the utility model, but any modifications, equivalents, improvements, etc. within the principles of the present utility model should be included in the scope of the present utility model.
