Abstract

The utility model discloses a stepped concrete heat-insulating building block, which belongs to the field of building materials and is used for building a heat-preserving wall body. The stepped concrete heat-insulating building block is characterized in that: a slurry fixing surface is divided into a high plane and a low plane and is in the shape of a step; heat-insulating through holes are distributed in the slurry fixing surface; heat-insulating ditches are formed in the two ends of the building block respectively; and heat-preserving materials are inserted into the heat-insulating through holes and the heat-insulating ditches. The heat-preserving wall body formed by building the building blocks does not have a horizontal mortar joint cold bridge; the energy-saving effect of the wall body is obviously improved; and the seismic performance is obviously enhanced.

Description

The adiabatic building block of a kind of stairstepping concrete

Technical field

The application belongs to construction material.

Background technology

Compare with other wall thermal insulating form, use the self heat insulation wall of self-insulating concrete building block that the advantage of himself is arranged, as reduced heat bridge and heat transfer area, obviously improved the thermal and insulating performance of body of wall; When masonry panel, disposal molding, very convenient; Be easy to guarantee workmanship; And need not adopt other any special heat insulation measure, and solved the globality and the weatherability of building heat preservation heat insulation wall, make the application life of wall insulation system consistent with building; The adhesion strength of self heat insulation wall and cement is high, and its exterior wall finish construction is simple, firm, has solved problems such as the easy hollowing of other heat-preserving wall exterior wall finish comes off.Simultaneously, the self heat insulation wall cost is low, and is convenient to detect and the control quality, has reduced the construction cost of heat-insulation system.In a word, because above-mentioned plurality of advantages, self-insulating concrete building block and body of wall thereof will have broad application prospects, and develop and develop this technology, will advance China's building energy conservation work to develop in a healthy way, and have significant social and technology economy advantage.But present self heat insulation wall, its horizontal mortar joint all are planes, and heat insulation effect is poor, and the cold bridge problem is outstanding, makes that the self heat insulation wall energy-saving effect is not ideal enough.Moreover present self heat insulation wall only depends on the bonding connection of masonry mortar between each skin building block, and anti-seismic performance is relatively poor.These all are the difficult problems that current urgent need solves.

Summary of the invention

The objective of the invention is to eliminate the horizontal mortar joint cold bridge of body of wall, significantly improve the energy-saving effect of heat-preserving wall, significantly improve the body of wall anti-seismic performance simultaneously, its technical scheme is following:

1, process concrete hollow block with concreting, its slurry surface is divided into two planes of height, is step, be distributed with adiabatic through hole on the step slurry surface, and respectively there is an adiabatic groove at the building block two ends, and is as shown in Figure 1.This is semiproduct, is named as the stairstepping concrete hollow block.

2, within the adiabatic through hole and adiabatic groove of semiproduct stairstepping concrete hollow block, insert heat insulating material such as foam-plastic blocks etc., finished product, be named as the adiabatic building block of a kind of stairstepping concrete, see Fig. 3.Find out that as can beappreciated from fig. 3 because the heat insulating function of the adiabatic groove and the heat insulating material of filling out thereof, insulation blocks end cold bridge has been eliminated in the adiabatic building block of this species stage shape concrete, has obviously improved the heat-preserving wall energy-saving effect.

3, process the cuboid concrete hollow block with concreting, as shown in Figure 2, its slurry surface is a plane; Be distributed with adiabatic through hole on it; And respectively there is an adiabatic groove at the building block two ends, and this also is semiproduct, is named as the cuboid concrete hollow block.

4, within the adiabatic through hole and adiabatic groove of semiproduct cuboid concrete hollow block, insert heat insulating material such as foam-plastic blocks etc., finished product, be named as the adiabatic building block of cuboid concrete, see Fig. 4.It belongs to the auxiliary specification building block of the adiabatic building block of a kind of stairstepping concrete, and the adiabatic groove at its two ends and the heat insulating material of filling out thereof have been eliminated building block end cold bridge.

5, semiproduct illustrated in figures 1 and 2 also can be the vitrified bond goods.

6, the building method of the adiabatic building block of a kind of stairstepping concrete:

(1) it is as shown in Figure 5 to build top plan view by laying bricks or stones;

(2) body of wall plummet sectional drawing is as shown in Figure 6;

(3) the building wall stereogram is as shown in Figure 7.

Can find out that from Fig. 6 and Fig. 7 the heat-preserving wall horizontal mortar joint has become the step plane by a traditional horizontal plane, horizontal mortar joint heat transfer distance significant prolongation is so body of wall horizontal mortar joint cold bridge is eliminated.

As can beappreciated from fig. 6, the adjacent two skin building blocks of body of wall fasten each other, so the body of wall anti-seismic performance significantly improves.

The application's good effect is:

(1) eliminated insulation blocks end cold bridge and heat-preserving wall horizontal mortar joint cold bridge, the heat-preserving wall energy-saving effect significantly improves.

(2) improved the body of wall anti-seismic performance.
