Abstract

The invention discloses an I-shaped hollow building block. A recess is respectively formed on both ends of a hollow building block for construction, thereby changing the building block into an I shape. In the masonry process of walls by using the I-shaped hollow building blocks, a closed cavity having the heat insulating function is enclosed by the recesses of two left-right adjacent building blocks and upper-lower adjacent building blocks, and therefore, cold/heat bridges at both ends of the building blocks are eliminated, the cold/heat transfer of the vertical mortar joint is cut off, and the energy-saving effect of the constructed outer wall is obviously improved.

Description

I-shaped hollow building block

Technical field

The application relates to constructional materials.

Background technology:

The heat-preserving wall that uses divides four big classes at present, be single heat-preserving wall, inside heat insulation wall body, external heat insulating wall and sandwich heat preserving wall body, wherein single heat-preserving wall construction is the simplest, do not exist insulation layer to come off and problem such as wall stability difference, the most reliable, cost is also minimum, and is well received, as hollow brick, building-block, porous brick and porous building-brick etc.But, hollow building blocks for outer wall or the porous building-brick that uses all is cuboid or square at present, though its heat insulating effect is much better than solid block or solid brick, there is serious cold and hot bridge effect in the building block two ends, make the energy-saving effect of body of wall have a greatly reduced quality.We should research and develop the building building-block that can eliminate or significantly reduce this cold and hot bridge effect energetically.

Summary of the invention

The present invention seeks to thoroughly to eliminate the cold and hot bridge at building building-block two ends, and manage significantly to reduce the cold and hot transmission of body of wall perpends, technical scheme is as follows:

(1) volume adequacy that will build building-block is done greatly, and makes I shape, and promptly end face and bottom surface all are I shapes, are named as I-shaped hollow building block, see Fig. 1;

When (2) building by laying bricks or stones with the skin I-shaped hollow building block, the groove of adjacent two building blocks surrounds the adiabatic cavity of a sealing with neighbouring building block, is named as building block termination cavity, sees Fig. 3.Building block termination cavity has been eliminated the cold and hot bridge at building block two ends, and has cut off the cold and hot transmission of perpends, and the energy-saving effect of external wall is significantly improved;

When (3) I-shaped hollow building block of different skins was built by laying bricks or stones, the adjacent two skin I-shaped hollow building blocks building block length that will stagger mutually half made perpends can not form vertical masonry joint, guaranteed wall stability, saw Fig. 4;

(4) I-shaped hollow building block can be a sintered hollow building block, also can be non-sintered hollow building block such as concrete hollow block etc.

The application's good effect is:

1) heat transfer at I-shaped hollow building block two ends is owing to be subjected to the obstruct of building block termination cavity, and the cold and hot bridge effect at building block two ends is thoroughly eliminated;

2) body of wall of building by laying bricks or stones with I-shaped hollow building block, perpends is cut off by building block termination cavity, and the cold and hot bridge effect of its body of wall perpends is thoroughly eliminated.

1---wide cavity; 2---narrow cavity; 3---groove; 4---building block termination cavity; 5---perpends; 6---I-shaped hollow building block; 7---auxiliary block of concrete; 8---horizontal mortar joint.

The specific embodiment

As Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, Fig. 5 is a kind of I-shaped hollow building block, and Fig. 6 is its auxiliary block of concrete, they all are to make with pea gravel concreten or cement mortar, dimensional units is mm among the figure, and it builds plan view by laying bricks or stones as shown in Figure 3, and it builds elevation by laying bricks or stones as shown in Figure 4.

When building a certain position of body of wall by laying bricks or stones,, then can build by laying bricks or stones with auxiliary block of concrete if can't use I-shaped hollow building block to build by laying bricks or stones.

For improving the heat insulating effect of outer body of wall integral body, can adopt the heat-insulating masonry mortar masonry panel.

Claims

1. I-shaped hollow building block is characterized in that:

(1) all there is a groove at the building block two ends, make block profile be I-shaped;

When (2) it is built by laying bricks or stones, the groove of adjacent two building blocks in the left and right sides surrounds an enclosed cavity that plays a role in insulation with neighbouring building block, thereby has eliminated the cold and hot bridge at building block two ends, and cut off the cold and hot transmission of perpends, the energy-saving effect of external wall is significantly improved.
