Description

A building structure that prevents the thermal bridge effect on the wall surface and prevents moisture on the ground

technical field

The invention relates to a building structure for preventing thermal bridge effect on the wall surface and moisture-proofing the ground, and relates to the field of civil engineering.

Background technique

In northern my country, the indoor temperature is generally high and the outdoor temperature is low in winter, so some parts of the external enclosure structure of the house will form an area with relatively dense heat flow and low indoor surface temperature under the action of the outdoor and indoor temperature difference. These parts become bridges with more heat transfer, so they are called thermal bridges. Thermal bridges can cause condensation, mildew and even dripping water on the inner walls of the house, which in turn affects the aesthetics of the walls and the living environment.

The corners of buildings are areas where thermal bridges are prone to occur. At the same time, ground and underground moisture can easily enter the room. Therefore, under the joint action of thermal bridge effect and moisture, the wall at the bottom corner of the building is more prone to mildew. The traditional ground moisture-proof treatment mostly adopts the method of three asphalt and two felts, that is, the ground is damp-proofed by hot asphalt and felt. This approach is not only time-consuming, but also the moisture-proof effect is not very ideal.

Contents of the invention

Aiming at the deficiencies of the existing building structures, the utility model designs a building structure that prevents the thermal bridge effect on the wall surface and prevents moisture on the ground. Bridge effect and mildew on the wall caused by ground moisture.

In order to achieve the above object, the utility model adopts the following scheme:

The utility model prevents the thermal bridge effect of the wall surface and the building structure of the ground moisture-proof mainly including two parts, the first part is the building wall structure, and the second part is the ground moisture-proof layer structure.

Preferably, EPS interlayer T-blocks are selected as the building wall filling material. Among them, the masonry of T-shaped blocks can make the sides of the blocks interlock with each other, avoiding the transverse joints in the traditional masonry method. Therefore, the path of indoor heat transfer to the outside is well blocked, and the use of T-shaped blocks can reduce the lateral displacement between blocks and increase the stability of the wall.

Further, the middle of the T-shaped block contains T-shaped EPS foam, that is, polystyrene foam. Its thermal conductivity is very small, and at the same time, its exterior is wrapped with concrete blocks, and the air cannot form convection, thus reducing the possibility of indoor heat dissipation to the outside.

Furthermore, polyurethane external wall insulation boards are provided on the outside of the T-shaped block. The T-shaped block and the polyurethane exterior wall insulation board are bonded together by structural glue. In order to increase the connection strength, anchors are provided at the junction of the insulation board.

Furthermore, the outer side of the polyurethane external wall insulation board is coated with a waterproof mortar surface layer.

Furthermore, a layer of waterproof mortar leveling layer is laid under the bottom concrete structure layer.

Furthermore, two layers of EPS insulation boards are arranged under the waterproof mortar screed layer as a thermal insulation and moisture-proof structure. As a preference, a self-adhesive rubber asphalt waterproof membrane is arranged between the two layers of EPS insulation boards, and its construction process does not require hot melting, which can well protect the EPS insulation boards and waterproof and moisture-proof.

Furthermore, the lower layer of the bottom insulation board is provided with a waterproof mortar leveling layer and a fine stone concrete cushion.

The utility model adopts the above technology and has the following advantages: it can effectively prevent the wall corner mildew phenomenon caused by thermal bridge effect and ground moisture, and the construction process is convenient without hot melting, which saves time.
