Description

The angular self-insulation heat-insulating building block

Technical field

The application belongs to construction material.

Background technology

At present, compare with other wall thermal insulating form, use the self heat insulation wall of self heat-preserving 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 do not need to adopt other any special heat insulation measure, and solved 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 the 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 heat-preserving 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-saving Work to develop in a healthy way, and have significant society and technology economy advantage.Along with the continuous application of China's Self-insulating wall building block in Practical Project, also highlighted the problem of some existence:

(1) because horizontal mortar joint and the perpends place of heat insulation building block body of wall are easy to form cold bridge (heat bridge), greatly cut down the heat-insulating property of building block.Form easily the phenomenon of cold bridge (heat bridge) for the perpends place, someone has taked the polyphenyl plate of building block is carried out the method that secondary inserts, namely after every layer of concrete block masonry is complete, between adjacent block, level is inserted polyphenyl plate, this obviously relative increase difficulty of construction, and at building block horizontal mortar joint place between layers, how to take effective Insulation, also need further further investigation.

(2) compare with traditional cuboid heat insulation building block, the anti-seismic performance of some novel self-insulated building block obviously improves, mainly be mutually to collude cover or mutually interspersed with skin-deep adjacent building block, but adjacent two skin building blocks still only depend on masonry mortar bonding, the ability of body of wall opposing horizontal thrust is large not enough, and necessity of further further investigation is quite arranged.

Summary of the invention

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

1, make traditional cuboid (perhaps square) shape heat insulation building block into following shape:

(1) master ga(u)ge lattice building block cross section is rectangular in shape, the fluted and plush copper of difference on the end face of building block two ends, and its stereogram is as shown in Figure 1;

(2) auxiliary specification building block cross section is rectangular, and its stereogram as shown in Figure 2.

As can be seen from Figure 1, the slurry surface of the present application building block has become step by traditional planar shaped, and the end face at building block two ends has become plummet by a traditional plummet face and has been folded flat face.Because the end face of application invention building block is plummet folding planar shaped, building block termination position heat transfer distance significant prolongation has been eliminated the cold bridge at building block two ends, so the present application building block belongs to a kind of heat insulation building block.Cross section owing to the present application building block is rectangular in shape again, so be named as the angular self-insulation heat-insulating building block.

2, on the angular self-insulation heat-insulating building block slurry surface and in the auxiliary specification building block (seeing Fig. 2), be distributed with adiabatic through hole, fill heat insulating material in the adiabatic through hole, such as Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5.

3, the angular self-insulation heat-insulating building block can be sintered article, also can be non-sintered article such as concrete block etc.

4, the building method of angular self-insulation heat-insulating building block is:

(1) body of wall building by laying bricks or stones of the first skin building block from bottom to top, its stereogram is as shown in Figure 3; Building by laying bricks or stones of the second skin building block, its stereogram is as shown in Figure 4; Building by laying bricks or stones of the 3rd skin building block, its stereogram is as shown in Figure 5; Building by laying bricks or stones of the 4th skin building block, its stereogram is and for example shown in Figure 4, and the rest may be inferred by analogy for it.

(2) the building wall stereogram as shown in Figure 6.

(3) wall body vertical sectional drawing, as shown in Figure 7.

Can find out that from Fig. 3, Fig. 4, Fig. 5, Fig. 6 the perpends of angular self-insulation body that heat-insulating building block is built a wall has been become plummet and has been folded flat face by a traditional plummet face, perpends heat transfer distance significant prolongation is so body of wall perpends cold bridge is eliminated.

As can be seen from Figure 7, the horizontal mortar joint of angular self-insulation body that heat-insulating building block is built a wall has become the step plane by a traditional horizontal plane, and horizontal mortar joint heat transfer distance significant prolongation is so body of wall horizontal mortar joint cold bridge is eliminated.

Can find out that from Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7 adjacent block is all colluded cover mutually in the angular self-insulation body that heat-insulating building block is built a wall, so wall stability is significantly increased than traditional blockwork, the body of wall anti-seismic performance significantly strengthens.

The angular self-insulation heat-insulating building block is used for building by laying bricks or stones non-bearing heat-preserving antidetonation body of wall.

The application's good effect is:

(1) eliminated all cold bridges of body of wall, energy-saving effect significantly improves;

(2) adjacent block is colluded mutually cover, and the body of wall anti-seismic performance significantly strengthens.
