Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to an external wall structural column thermal insulation structure. Background Art

[0002] As people's environmental awareness increases, the demand for environmentally friendly materials in the construction industry continues to increase. Autoclaved aerated concrete blocks, as a lightweight, sound-insulating and thermally insulating building wall material, have gradually been widely used in construction projects. During the construction of autoclaved aerated concrete block walls, in order to enhance the stability and seismic performance of the wall, it is necessary to set structural columns at specified positions such as the corners and middle of the wall. The structural columns are usually connected to the ring beams of each floor of the building, thereby forming a space frame that can resist bending and shearing, which is an effective measure to prevent house collapse.

[0003] Existing structural columns are usually constructed by directly pouring concrete, which has a much higher thermal conductivity than autoclaved aerated concrete block wall materials. When the temperature difference between indoor and outdoor is large, the heat will be concentrated on the structural column with good thermal conductivity to form a "thermal bridge". This phenomenon will not only cause condensation and moisture on the wall surface, but may also cause problems such as wall peeling and mildew, affecting the service life of the building and the indoor environment. The existing technology usually pastes an insulation layer on the outside of the structural column, but this method is not only cumbersome and costly in construction, but also may be affected by various factors such as the natural environment and human factors during long-term use, resulting in damage, aging or peeling, and has poor durability. Summary of the invention

[0004] The utility model aims to provide an external wall structural column insulation structure to solve the problems of cracking, sinking and the like that are easy to occur around the existing well inspection.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An exterior wall structural column insulation structure includes structural column steel bars, multiple first aerated concrete block layers and multiple second aerated concrete block layers alternately built up and down, a tooth-jointed column-shaped cavity surrounded by the first aerated concrete block layer, the second aerated concrete block layer and the left and right walls, concrete poured in the cavity, and an insulation board arranged in the first aerated concrete block layer and the second aerated concrete block layer, the structural column steel bars are located in the cavity, the first aerated concrete block layer includes four L-shaped blocks spliced ​​to each other, and the second aerated concrete block layer includes two L-shaped blocks spliced ​​to each other.

[0007] Preferably, the four L-shaped blocks in the first aerated concrete block layer are spliced ​​together to form a hollow cubic structure, and the two L-shaped blocks in the second aerated concrete block layer are spliced ​​together to form a U-shaped structure.

[0008] Preferably, a transverse plate parallel to the long side is provided on the inner side of the short side of the L-shaped building block, an L-shaped side plate is provided at the end of the long side of the L-shaped building block, the short side of the L-shaped side plate is arranged opposite to the transverse plate, and the insulation board is clamped between the transverse plate and the L-shaped side plate.

[0009] Preferably, the height of the insulation board is the same as the height of the L-shaped building block, and the insulation board is a flexible insulation board.

[0010] Preferably, the first aerated concrete block layer is located at the bottom layer.

[0011] Preferably, the outer surface of the short side of the L-shaped building block is provided with a plurality of convex patterns.

[0012] Preferably, the short side of the L-shaped block is provided with a plurality of through holes.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] 1. The utility model forms a composite thermal insulation structure by arranging thermal insulation boards in the first aerated concrete block layer and the second aerated concrete block layer. The L-shaped aerated concrete blocks in the aerated concrete block layer slow down the transfer of heat flow due to their unique porous structure, providing a basic thermal insulation effect for the wall. The thermal insulation boards further reduce the transfer of heat energy, avoid the thermal bridge phenomenon, greatly improve the thermal insulation performance of the building, and improve the living comfort and durability of the building.

[0015] 2. The utility model forms a tooth-jointed cavity structure with the wall through the alternating upper and lower aerated concrete blocks, which not only ensures the close connection between the structural column and the wall, improves the stability and seismic performance of the overall structure, but also creates a continuous closed space for internal concrete pouring. The structural column construction can be completed without setting up and dismantling the formwork, which greatly saves material and labor costs, reduces construction difficulty, and improves construction efficiency.

[0016] 3. The utility model uses lightweight aerated concrete blocks as building blocks, combined with concrete cast structural columns, to achieve the complementary advantages of lightweight materials and heavy materials, which not only reduces the weight of the building, but also ensures the stability and safety of the structure;

[0017] 4. The utility model forms a stable clamping space through the L-shaped side plate and the cross plate, so that the heat insulation board can be firmly fixed inside the L-shaped block and is not easy to shift. The heat insulation board is consistent with the height of the L-shaped block, ensuring the integrity of the wall and avoiding the generation of thermal bridges. The heat insulation board made of flexible material enables the heat insulation board to better adapt to the space inside the block, ensuring the integrity and sealing of the heat insulation layer, thereby improving the thermal insulation effect of the structural column;

[0018] 5. The utility model can improve the adhesion between the block and the mortar by arranging convex patterns on the outer surface of the short side of the L-shaped block, thereby improving the firmness and durability of the entire wall structure. By arranging a plurality of through holes through the short side of the L-shaped block, the weight of the L-shaped block can be reduced, making it more convenient to carry and install, and allowing concrete to flow into the gap between the L-shaped block and the left and right walls, thereby forming an integral structure, reducing the occurrence of cracks, and greatly enhancing the strength and stability of the wall structure.

The structural column construction can be completed without setting up and dismantling the formwork, which greatly saves material and labor costs, reduces construction difficulty, and improves construction efficiency. Insulation boards 4 are arranged in the first aerated concrete block layer 1 and the second aerated concrete block layer 2 to form a composite insulation structure.
