CN202466948U - Self-heat preserving building block with skin - Google Patents

Abstract

The utility model discloses a self-insulating block with a skin, which is composed of a load-bearing skeleton with a skin and a heat-preservation cavity. The frame consists of longitudinal ribs and skin. 4 longitudinal ribs are located at the four corners, 2 longitudinal ribs are located in the middle of the long side, skins are connected between the longitudinal ribs, and foam concrete or other thermal insulation materials are filled in the thermal insulation cavity. The block overcomes the disadvantages of large volume and easy cracking of ordinary concrete blocks, and also has the advantages of light weight, good thermal insulation performance, high bearing capacity, and strong processability. Therefore, the block is especially suitable for load-bearing walls with energy-saving requirements.

Description

A self-insulating block with skin

technical field

The application relates to an energy-saving building wall material, more precisely a self-insulating block with a skin. the

Background technique

Green energy saving has become the mainstream trend of building development. As the country puts forward the goal of building new housing with energy saving of more than 60%, various energy-saving blocks have sprung up like mushrooms. When considering light weight, bearing capacity and energy saving, it is often easy to lose sight of the other. The blocks currently used in the construction industry mainly have the following shortcomings: 

1. The crack resistance is poor. Some blocks with multiple rows of holes pursue energy saving, and the outer wall is too thin, which is easy to cause the block to crack when subjected to external force;

2. The bulk density is heavy, and the load-bearing wall accounts for a certain proportion of the overall mass of the building. The greater the mass, the greater the inertial force suffered during an earthquake, and the requirements for the bearing capacity of the block are also increased accordingly;

3. The bearing capacity is not enough, and some blocks are too light, which leads to the loss of the bearing capacity of the blocks to varying degrees;

4. The insulation performance is not ideal.

Contents of the invention

The patent of the present invention provides a skinned self-insulating block, which has the characteristics of simple shape, good crack resistance, light bulk density, high bearing capacity and good heat preservation performance. the

This application involves the skin effect, and its concept is elaborated as follows: the skin effect refers to the enhancement of the overall rigidity of the building by the use of its own stiffness and strength on the surface covering materials (roof panels and wall panels) of the building, and its concept In the construction industry, it is more common in light steel housing and portal frame systems. It is a ribbed thin shell structure formed by covering metal sheets on longitudinal and transverse ribs. The skin and ribs work together. The skin itself has great tensile, compressive and shear strength in its plane, and because of the ribbed As a result, the skin will not be unstable. The biggest advantage of the skin structure is that it has a large bearing capacity and rigidity, but its own weight is very light. the

The patent of the present invention is realized through the following technical solutions. ``

A skinned self-insulating block, including a skinned skeleton and an insulating cavity, characterized in that: the block has 6 longitudinal ribs, 4 of which are located at the four corners, 2 are located in the middle of the long side, and 4 are located at the four corners The thickness of the longitudinal ribs along the long side of the skeleton is the same and half of the thickness of the ribs in the middle of the long side. Furthermore, when the project actually requires the block to have a higher bearing capacity, 1 to 4 longitudinal ribs can be added at equal intervals in the direction of the two long sides of the block, and 1 to 3 ribs can be added at equal intervals in the direction of the two short sides of the block. For longitudinal ribs, 1 to 4 transverse ribs are added in the height direction, so that the number of longitudinal ribs along the length direction of the block is 2 to 7, and the number of ribs along the width direction of the block is 2 to 5. The number of transverse ribs along the block height direction is 1 to 4. the

The bottom of the skeleton is also made of concrete skin, and the back cover of the skin is very thin, with a thickness of 5mm to 10mm. The cross-section of the longitudinal and transverse ribs can be rectangular, semicircular or rhombus, and the material of the longitudinal and transverse ribs can be ceramsite concrete, fiber concrete or refractory concrete. The longitudinal ribs are connected by a concrete skin whose thickness is smaller than that of the longitudinal ribs, and the skin material is made of metal fiber concrete or organic fiber concrete or inorganic fiber concrete. The bottom of the frame is also a concrete skin, and the skin back cover is very thin, with a thickness of 5mm to 10mm. Its main function is to prevent leakage from the bottom when pouring thermal insulation materials. The thermal insulation materials are foamed concrete or styrene particles or foamed particles. the

For walls with high load-bearing requirements and relatively low thermal insulation requirements, transverse ribs can be set in the middle of the four-sided longitudinal ribs of the skeleton to connect adjacent longitudinal ribs, and the effective height of the longitudinal ribs can be reduced to further improve the bearing capacity of the blocks. The demoulding process requires that the blocks with transverse ribs have no skin back cover and are only used for load bearing and not for heat preservation. When transverse ribs are added, the dimensions of the longitudinal ribs can be exactly the same. the

Compared with the prior art, the patent of the present invention has the following characteristics:

1. Good crack resistance;

2. Small bulk density and high bearing capacity;

3. Ideal thermal insulation performance.
