Description

I-shaped pumice functional compound light aggregate thermal insulation block

technical field

The utility model relates to a light aggregate wall body block, in particular to an I-shaped pumice function composite light aggregate heat preservation block, which is used for building walls of various buildings.

Background technique

An existing light aggregate wall block needs to be used as an external wall to make an insulation layer on the outside of the wall. The construction is very troublesome and increases the cost; moreover, the insulation layer is easy to separate from the wall and may be affected by external forces. Impact and damage, lower service life.

Contents of the invention

The purpose of this utility model is to provide an I-shaped pumice functional compound light aggregate thermal insulation block to solve the problems of troublesome construction, high cost, easy detachment of the thermal insulation layer from the wall and low service life in the prior art.

The technical solution of the utility model is: comprising a main body made of light aggregate, characterized in that an I-shaped through hole communicating with the upper and lower end faces is provided in the middle of the main body, and Outer grooves corresponding to the left and right sides of the I-shaped through hole.

The upper and lower horizontal holes or/and vertical holes of the I-shaped through holes are filled with light heat insulating materials (any existing light heat insulating materials can be used), and the vertical holes can be vacant or partially vacant.

The lightweight heat insulating material can be polystyrene foamed board (EPS), and a polystyrene foamed board with matching sections is inserted into the upper and lower horizontal holes and/or vertical holes of the I-shaped through hole, Or insert two horizontal polystyrene foam boards in the vertical hole, between each of the horizontal polystyrene foam boards and between the polystyrene foam boards in the upper and lower horizontal holes There is an interval between them.

The lightweight thermal insulation material can also use vitrified microbeads compounded with polystyrene particle thermal insulation slurry.

The utility model has the advantages that the thermal bridge between the inner and outer layers of the wall is extended by using the cooperation of the I-shaped through hole and the outer grooves on both sides, and the heat insulation effect of the wall is greatly improved; Filling the groove with thermal insulation material can further improve the thermal insulation effect; especially when EPS foam board is used and some space is left in the vertical hole in the middle, the block has better thermal insulation properties.

Detailed ways

Referring to Fig. 1 and Fig. 2, the utility model comprises a main body 1 made of light aggregate, in the middle of the main body 1 is provided with an I-shaped through hole 2 communicating with its upper and lower end faces, on both sides of the main body 1 Outer grooves 3 corresponding to the left and right sides of the I-shaped through hole 2 are provided.

Referring to FIG. 3 and FIG. 4 , a polystyrene foam board 4 with matching sections is inserted into the upper and lower horizontal holes of the I-shaped through hole 2 . Two horizontal polystyrene foam boards 5 are inserted into the vertical hole in the middle, between each of the horizontal polystyrene foam boards 5 and between the polystyrene foam boards 4 in the upper and lower horizontal holes. There is space between them. It is also possible to insert a section matching polystyrene foam board (not shown) in the vertical hole in the middle or leave the vertical hole vacant. In addition to the EPS foam board, the lightweight thermal insulation material can also use vitrified microbead composite polystyrene particle thermal insulation slurry, or any existing lightweight thermal insulation material.

A typical external dimension of the utility model is 390mm * 240mm * 190mm (the left and right dimension in Fig. 1 * the up and down dimension * the left and right dimension of Fig. 2). The size of the blocks can also be determined according to the actual situation of the wall.

As shown in Figure 4, when the utility model is applied, the holes formed by the opposite outer grooves 3 between adjacent blocks can also be filled with heat-insulating materials, which can be filled, and polystyrene with a length shorter than the hole ends can also be inserted. The vinyl foam board 6 leaves spaces at both ends thereof.

After the inspection of the National Construction Engineering Quality Supervision and Inspection Center, the combination of blocks shown in Figure 4 above (the heat insulation material is polystyrene foam board) and the combination of blocks filled with vitrified microbeads and polystyrene particles for thermal insulation slurry Quality, in line with relevant national standards (the specific test data will not be repeated here, please refer to the number BETC-JN1-2007-237; BETC-JN1-2007-238; BETC-CL2-2008-9(A) and BETC-CL2 -2008-10(A) inspection report). In particular, the test results of the thermal resistance and heat transfer coefficient of the above two blocks are as follows:

Block shown in Figure 4: thermal resistance R = 1.54m ² .K/W,

Heat transfer coefficient K＝0.59W/(m ² .K)

Blocks filled with vitrified microbead composite polystyrene particle insulation slurry:

Thermal resistance R=1.1m ² .K/W,

Heat transfer coefficient K＝0.79W/(m ² .K)

It can be seen from the above test results that the structure of the block shown in Figure 4 (the heat insulation material is polystyrene foam board, and the vertical holes in the middle are spaced) has a better heat preservation effect.
