Description

Double-concave-convex fly ash aerated concrete block and its masonry method

technical field

This application relates to building blocks.

Background technique

The traditional fly ash aerated concrete building blocks, whether it is a wall block or a corner block, are all cuboid, and the seismic performance of the wall is poor. A cold bridge is formed, so the thermal insulation performance of the wall, that is, the energy saving performance is also poor. To improve the energy-saving and seismic performance of the wall, it is necessary to improve the shape of the block.

Contents of the invention

The purpose of the invention is to improve the anti-seismic performance and thermal insulation performance of the wall body.

Technical scheme of the present invention is as follows:

1. The wall blocks and corner blocks are made of fly ash aerated concrete.

2. The wall block is changed from the traditional cuboid shape: one top surface has a convex head, the other top surface has a groove, and other surfaces such as two strip surfaces and two large surfaces are still flat. see picture 1. Because the convex direction of the convex head of the wall body block and the concave direction of the groove are on the same straight line, it is named the inline fly ash aerated concrete concave-convex block.

3. The corner block is changed from the traditional cuboid shape: one top surface has a convex head, the other top surface is still flat, one strip surface is grooved, the other strip surface is still flat, and the two large surfaces are still flat. As a plane, see Figure 2. Because the convex direction of the convex head of the corner block and the concave direction of the groove form an angle of 90°, it is called a right-angle fly ash aerated concrete concave-convex block.

4. The T-shaped corner block is changed from the traditional rectangular shape to two shapes:

(1) Double-concave-convex fly ash aerated concrete block: one top surface of the block has a convex head, the other top surface has a groove, one strip surface has a low table-shaped groove, and the other The noodles and the two large sides are all planes, as shown in Figure 3.

(2) Double-convex-concave fly ash aerated concrete block: one top surface of the block has a convex head, the other top surface has a groove, one strip has a raised platform-shaped convex head, and the other strip has a convex head. The face and the two large faces are planes, as shown in Figure 4.

5. The wall masonry method is as follows:

(1) Wall masonry

The one-shaped fly ash aerated concrete concave-convex block is used as the wall block. When building the wall, the convex end of one wall block is inserted into the groove of the adjacent wall block (see Fig. 5 Figure 6 and Figure 7), the convex direction of the convex head (or the concave direction of the groove) of the two adjacent skin wall blocks is just opposite (see Figure 5, Figure 6 and Figure 7).

The first skin masonry of the wall body is shown in Figure 5, the second skin masonry of the wall body is shown in Figure 6, and the third skin masonry of the wall body is shown in Figure 7, and the cycle is repeated. The elevation of the wall masonry is shown in Figure 8, and the three-dimensional view of the wall masonry is shown in Figure 9.

(2) Corner masonry of the wall

Use right-angle fly ash aerated concrete concave-convex blocks as corner blocks. When building the corner of the wall, the convex head of the corner block must be inserted into the groove of the adjacent wall block, as shown in Figure 10. 11 and Figure 12; the groove of the corner block is to be inserted by the protrusion of the adjacent wall block, see Figure 10 Figure 11 and Figure 12. During masonry construction, any two adjacent corner blocks at the corner of the wall, the convex direction of the convex head (or the concave direction of the groove) is exactly at an angle of 90°, see Figure 10, Figure 11 and Figure 12. In this way, the vertical mortar joints of two adjacent skin blocks can be staggered (see Figure 13) to increase the stability of the wall.

The first skin masonry diagram of the wall corner is shown in Figure 10, the second skin masonry diagram of the wall corner is shown in Figure 11, and the third skin masonry diagram of the wall corner is shown in Figure 12. A skin masonry diagram is the same. The three-dimensional view of the masonry at the corner of the wall is shown in Figure 13.

(3) T-shaped corner masonry of the wall

First build the first skin with double concave-convex fly ash aerated concrete blocks (see Figure 14), and then build the second skin with double convex-concave fly ash aerated concrete blocks (see Figure 15) , and build the first skin with double-concave-convex fly ash aerated concrete blocks (see Figure 16), repeating the cycle, and see Figure 17 for the three-dimensional view of the T-shaped corner of the wall. That is to say, when building a T-shaped corner of the wall, the double-concave-convex fly ash aerated concrete block and the double-convex-concave fly ash aerated concrete block are used alternately. , and their protruding heads and high platform-shaped protruding heads are all inserted into the grooves of adjacent inline fly ash aerated concrete concave-convex blocks (wall blocks), and their grooves and low platform-shaped grooves are all The protruding head of the adjacent one-shaped fly ash aerated concrete concave-convex block (wall block) is inserted to increase the seismic performance of the wall. In this way, the convex direction (or the concave direction of the groove) of the two adjacent one-shaped fly ash aerated concrete concave-convex concrete blocks adjacent to the wall can be just opposite, so that the adjacent two skin blocks can The vertical mortar joints are staggered from each other (see Figure 17) to increase the stability of the wall.

When building the wall, the corner of the wall and the T-shaped corner of the wall, the adjacent blocks are interspersed with each other, which significantly increases the seismic performance of the wall, and because the interspersed between adjacent blocks, The vertical mortar joints of the wall are changed from traditional flat seams to folded seams, the heat transfer path of vertical mortar joints is significantly extended, the cold bridge of vertical mortar joints is eliminated, and the energy-saving performance of walls is significantly improved.

The positive effect of the application is to significantly improve the anti-seismic performance and energy-saving performance of the wall.
