Description

Wall self-insulating blocks

technical field

The utility model relates to a wall thermal insulation block, in particular to a wall self-thermal insulation block, which belongs to the technical field of building thermal insulation.

Background technique

Wall reform and building energy conservation are a basic national policy of our country, and have developed rapidly in recent years. At present, building wall insulation technology mostly adopts the structural form of external wall insulation and internal insulation. Exterior wall insulation is the thermal insulation treatment on the outside of the building wall, such as pasting EPS boards, etc., which are prone to a series of problems such as cracking, falling off, water seepage, and fire during the application process, and are prone to occur at expansion joints and delamination joints. thermal bridge, reducing energy saving effect. The inner insulation of the external wall is to cover a layer of thermal insulation material on the inner side of the wall structure, fix it on the inner side of the wall structure with adhesive, and then make a protective layer and finish on the outer side of the thermal insulation material. Although this thermal insulation method avoids defects such as poor weather resistance, its thermal insulation effect on surrounding parts such as columns, floor slabs, and partition walls is not ideal, and thermal bridges are likely to occur, reducing energy-saving effects, and because the structural wall is outside, the heat capacity of the inner insulation layer is small. , The indoor thermal stability is poor, and secondly, the hanging and fixing objects on the inner wall are also easy to damage the inner insulation structure. Whether the building wall adopts external thermal insulation or internal thermal insulation technology, there is a big limitation, that is, the life of the heat insulation material used is short, and it cannot achieve the same life as the building, and there is intermediate maintenance and replacement costs at that time. advanced questions.

Therefore, the study of wall self-insulation is of great significance for building energy conservation.

Utility model content

Aiming at the above-mentioned many defects existing in the existing wall thermal insulation technology, the utility model provides a wall self-insulation block, and the building wall built with it has excellent thermal insulation performance, light weight, high strength, The problem of cold and heat bridges existing in the joints of the blocks is effectively solved, and the cost is low.

The utility model is realized through the following technical scheme: a wall self-insulation block, which is formed by combining two cuboid block bodies along the sides of the length direction, and the joint part combines the two block bodies into one , the two block bodies respectively have cavities passing through the upper and lower surfaces, and the cavities are respectively filled with lightweight heat insulating materials and/or foamed concrete.

The utility model increases the thermal resistance value of the block by filling the cavity of the block body with light heat insulating material and/or foamed concrete, prevents the transfer of heat, and thus achieves the effect of heat preservation and heat insulation. The block itself acts as a strength material. The foamed concrete filled in the cavity is connected by dense closed-cell air cells to form a block, and the closed air is used as a thermal resistance material, which has a good self-insulation effect. At the same time, the foamed concrete has a high compressive strength Strength, which can improve the overall strength of the block. In the utility model, the two cavities can be filled with lightweight heat insulating materials or foamed concrete at the same time, or one cavity can be filled with light heat insulating materials, and the other cavity can be filled with foamed concrete. In terms of thermal insulation effect and its strength and self-weight, the optimal solution is to fill the two cavities with lightweight thermal insulation material and foamed concrete respectively.

In order to improve the strength of the self-insulating block, the block body is a concrete slurry vibration extrusion molding structure.

As a structure of the present invention, the two end faces of the two block bodies located at one end along the length direction are located in the same plane, and the two end faces located at the other end are also located in the same plane. The thermal insulation blocks of this structural form are easy to assemble and simple to construct.

As another structure of the utility model, the two end faces of the two block bodies located at one end along the length direction are not in the same plane at least at one end.

A further solution is that one end face of one block body is indented relative to the other block body, and the other end face protrudes outward relative to the other block body.

Since the end surfaces of the two block bodies at the two ends of the thermal insulation block are not in the same plane at least at one end, when the thermal insulation block is used to build the wall, the joint between the two thermal insulation blocks is a zigzag joint. The seam changes the direction of heat transfer, and at the same time the heat transfer path becomes longer, which improves the thermal resistance and effectively solves the problem of cold and heat bridges in the seam. At the same time, this kind of joint construction can effectively prevent the generation of cracks in the wall.

The beneficial effects of the utility model are: its structure is simple, because the block body is hollow and the cavity of the block body is filled with light heat insulating material and/or foamed concrete, the overall weight of the heat preservation block is light, and its self-insulation insulation The thermal effect is good. Using the utility model to build the wall can effectively ensure the thermal insulation performance of the building, and can effectively reduce the self-weight of the building, reduce the labor intensity of the wall construction, and reduce the total cost of the building; The zigzag joints effectively solve the problem of hot and cold bridges at the joints and improve the thermal insulation performance of the wall; the utility model solves the integrity and weather resistance of the thermal insulation wall of the building because it can be built into a wall alone In addition, the thermal insulation block of the utility model is easy to produce, the cost is low, and its construction is simple and efficient, which is beneficial to reduce the construction cost.
