Abstract

The present invention relates to a new technology for light hollow heat preservation building block reinforcing bar core pouring supporting systems. Building blocks in use have two kinds: one kind is an EPS hollow concrete building block which is a regular hexahedron and one side surface of the EPS hollow concrete building block is provided with a semicircular transverse groove and a vertical groove which are communicated; the other kind is a hollow foaming powder coal ash building block provided with an upper penetrated circular hole and a lower penetrated circular hole and the downside of the hollow foaming powder coal ash building block is provided with a cambered groove in the horizontal direction. When the hollow building blocks are used for stacking and building, the building blocks are stacked in a stagger mode, and upper pore canals, lower pore canals, left pore canals and right pore canals are aligned. Steel bars are arranged in the pore canals, and concrete is used for pouring the pore canals to form steel bar concrete supporting walls in a grid shape. The supporting system can keep heat and support weight.

Description

The reinforcement and pouring of bearing system of light thermal insulation hollow block new technology

The present invention relates to a kind of reinforcement and pouring of bearing system of light thermal insulation hollow block new technology, belong to the novel building design, construction technology and building material technical field.

The existing building load bearing wall of China is many builds by laying bricks or stones with clay brick, from destroy soil, contaminated environment and waste can be former etc. the aspect consider the use of country's strict restriction clay brick.(1) the little building block of the concrete hollow that adopts in the building design and construction can only be covered six floors in the 8 ° of areas of providing fortification against earthquakes, and its temperature deformation is big, and moisture content is difficult to control, and easy to crack after building by laying bricks or stones, wall leakage is serious, and this problem can not get solving for a long time.(2) cast-in-place concrete scissors wall uses steel form in a large number, and punching block is from great, and the assembly unit dismounting bothers, and is time-consuming, and form cost is with high.(3) little building block of concrete hollow and cast-in-place concrete shear wall conduct heat soon, need add heat-insulation layer in addition at cold district, and the exterior wall outer surface is established heat-insulation layer, the expense height, and difficulty of construction is big, and the surface is the crack easily.The little blockwork inner surface of concrete hollow is established heat-insulation layer, though expense is lower than outside insulation, summer in body of wall winter, the temperature difference was big, easily caused the upper strata wall crazing.

With the immediate prior art of the application be documents 1, this document 1CN86107290A is U.S. Hai Tai, Ke Huomu company is as applying in Patent Office of the People's Republic of China on October 26th, 86, open as on May 11st, 1988, its content is for to be installed on the soleplate with light-duty synthetic resin wall panelling, constitute mould between its slot wedge, this mould can be used to make the structural upright of band reinforcing bar, each covers the woven wire that is used for fixing concrete surface layer the surfaces externally and internally layer of wall, intermediate floor panelling and roofing panelling have groove, the structural member of reinforcement pours in this groove, formation has column and tectal overall structure, and left and right sides adjacent block forms vertical and horizontal hole.

The objective of the invention is at present construction wall structural thermal insulation, the problem that aspects such as load-bearing and construction technology exist, the needs of adaptation wall reform provide a kind of reinforcement and pouring of bearing system of light thermal insulation hollow block new technology.Adopt this technology, can make heat-preserving load-bearing integrated, it is simpler to construct, and avoids concrete wall to expose, and reduces temperature stress, improves anti-seismic performance, and the energy saving of work and time, saves engineering cost.

Now disclose as follows to content of the present invention in conjunction with Figure of description 1-11:

The used building-block of the present invention has two kinds, one is the EPS concrete hollow block, be the regular hexahedron shape, there is semicircle translot (1) and the vertical slot (2) that interpenetrates a side, and the another side accompanies one deck alkali-proof glass screen cloth (3) apart from the surperficial a distance of EPS concrete (4); During with this kind concrete block masonry, make face that two building blocks have a groove anyhow in opposite directions, being that pitch is staggered according to half building block length bonds together, making section is the synthetic circular cross section duct of semicircular translot, configuration vertical and horizontal steel bar stress (5) in this duct, use self-compaction then, the chutable concrete grout of microdilatancy solidifies the back and forms reinforced column (6); Another kind is the foaming coal ash building-block, be the regular hexahedron shape, on having, under run through circular hole (7), its bottom side horizontal direction has arcuate recess (10), groove (10) with run through circular hole (7) and interpenetrate in building block inside, during with this kind concrete block masonry, being that pitch is staggered according to half building block length bonds together, the circular hole (7) that runs through of levels building block is aimed at, the arcuate recess of left and right sides adjacent block (10) is aimed at, form vertical and horizontal hole, in this sky road, dispose steel bar stress (5), with self-compaction, the chutable concrete grout of microdilatancy, solidify the back and form reinforced column (6), the whole bearing system of exterior wall in forming with lightweight concrete building block is common is in it, exterior wall surface can or paste tapestry brick outward according to the direct sprayed coating of the block performance of different cultivars.

Advantage of the present invention and effect are as follows:

1, the body of wall of building by laying bricks or stones with the technology of the present invention connects the latticed reinforced concrete structure of all-in-one-piece owing to forming in body of wall inside, good integrity, and the body of wall of building by laying bricks or stones with general masonry compares, and anti-seismic performance improves greatly.

2, the used light-weight hollow building block made of the present invention, the inside and outside heat-insulation layer of double as exterior wall can be avoided heat bridge, reduces energy consumption, heat transfer coefficient≤0.8w/m ²K, thermal environment is stable, is a kind of good energy-saving heat preserving scheme.

3, building block is from heavy and light, easy construction, and the EPS concrete segment can be sawn into arbitrary dimension, and building block core hole configuration reinforcement is convenient, can satisfy the load-bearing needs of multilayer or skyscraper.

4, the armored concrete core body of exterior wall load-bearing does not expose fully, and summer in winter, difference variation was little, reduces temperature stress and destroys, and helps the load-carrying members protection.

5, light-weight hollow building block made reinforcement and pouring of bearing body of wall belongs to non-combustion body, and fire resistance is good, and multilayer or fire prevention to high buildings requirement can be satisfied in fire endurance 〉=4 hour.

6, the outer body of wall of light block is not established heat-insulation layer in addition; irritate core without template; load-bearing is heat insulation integrated, significantly reduces operating expenses, promotes easily; but substitute for clay brick; make raw material with flyash or waste old polystyrene foamed plastic, reduce environmental pollution, it is sharp useless to reuse; meet wall reform and building energy conservation, the state basic policy of environmental protection.
