Abstract

The invention relates to a pre-placed recycled aggregate grouted concrete energy-saving and heat-preservation building block and a wall system. The heat-preservation building block is formed by cementing broken tiles used as recycled aggregate and cement slurry which has definite strength and is used as a cementing material. A meshy reinforcement block wall is formed by laying heat-preservation building blocks in the mode that clamped and fixed type steel reinforcement meshes are used in horizontal mortar joints, horseshoe-shaped sleeve ribs are used in vertical mortar joints and #-shaped steel reinforcement meshes are used at constructional columns. The heat preservation performance of construction waste such as the tiles is fully used, the bearing capacity and integrality of a wall structure are improved, meanwhile, semi-industrialization of masonry structure construction is achieved, and construction efficiency is improved remarkably.

Description

A kind of preparation method of preset regeneration aggregate grouted-aggregate concrete energy-saving heat preservation building block and walling system
Art
The present invention relates to a kind of Novel energy saving thermal insulation building block and the walling system by this concrete block masonry, have advantage that is energy-conservation, that be incubated and improve bearing capacity of wall body, globality concurrently, be conducive to half industrialization realizing walls with brick masonry structure body construction.
Background technology
Along with deeply carrying out of wall reform, loam brick exits construction market gradually.The brickbat watt discarded object produced due to housing demolition unprecedentedly increases, to 30%-50% of total building waste amount be reached according to preliminary estimation, this overwhelming majority is wherein without any process, just countryside air storage or landfill is transported to, consume the construction investments such as a large amount of expropriations of land, what produce is scattered and the problem such as airborne dust thereupon simultaneously, has increased the weight of again the pollution to environment, as by its resource recycling, then meaning is very large.In addition, concrete small size hollow building block is widely used as body of wall main material, but there is the problems such as thermal and insulating performance difference, globality is poor, labor productivity is low.And existing light heat insulating material complex manufacturing, cost is higher.
The present invention makes full use of brickbat watt discarded object; a large amount of brickbat watt offal treatment difficulty can be solved on the one hand and to problems such as the negative effects of environment, reduce the exploitation to natural sandstone, preserve the ecological environment; can utilize the heat insulating ability production building block of brick and tile on the other hand, environmental protection and energy saving profit is useless.In addition, the present invention forms reinforced network blockwork by using buckle type reinforced mesh and shape of a hoof cover muscle to build building block by laying bricks or stones, improves bearing capacity and the globality of body of wall.
Summary of the invention
The object of the invention is to make full use of the heat-insulating property that brickbat watt waits building waste, overcome the complexity of existing insulation blocks manufacture craft, reduce costs, the insulation blocks that a kind of manufacture craft is simple, cost is low and the energy-saving wall system that bearing capacity is high, globality is high are provided.
The technical solution adopted for the present invention to solve the technical problems is: make energy-saving heat preservation building block by preset regeneration aggregate grouted-aggregate concrete, by using buckle type reinforced mesh in horizontal mortar joint, using the shape of a hoof to overlap muscle, constructional column place use groined type reinforced mesh building heat insulation building block formation reinforced network blockwork system in perpends.
Described insulation blocks is watt for aggregate with discarded brickbat, take cement paste as cementitious materials, particular manufacturing craft and preset regeneration aggregate grouting is adopted to make building block, aggregate also can adopt the lightweight aggregate such as rubble or slag, and cement paste can be foam slurry, the light water mud being mixed with the admixtures such as flyash or other cementitious materials slurries that physical blowing method is produced.When shockproof requirements is higher, block interiors establishes reinforcing cage to improve building block globality, and building block both sides establish the shape of a hoof to overlap the level connection joint of muscle for blockhouse, and when blockwork, cover muscle curved end can upwards make it just in time to withstand mould by 90-degree bent.
Described particular manufacturing craft is have with steel or other sectional die being convenient to mount and dismount that material of sufficient intensity makes, and mudhole is established in mould bottom, as need in building waste site prefabrication building block, then and should in mould two side grip and lifting point.
The manufacturing process of described insulation blocks is: on bed die, assemble surrounding side form, put into reinforcing cage, at regeneration aggregate broken scene, aggregate is loaded mould, aggregate is rinsed with clear water after transporting precast yard back, blocking mudhole, pour into cement paste and swing die, reach after side form removes intensity and remove side form, after reaching lifting intensity, component is hung bed die.
When described reinforced network blockwork is built by laying bricks or stones, the building block of buckle type reinforced mesh drawknot is used in horizontal mortar joint, the longitudinal rib of reinforced mesh, be placed on the bottom of horizontal bar, in the groove on i.e. every block building block top, inserts a perpendicular muscle in the middle of after the shape of a hoof cover muscle socket in perpends between building block, this shape of a hoof cover muscle also can be lifting building block and uses, constructional column place groined type welded reinforcement mesh sheet is held concurrently stirrup, with pecten fixture construction post warming plate.
Beneficial effect of the present invention is that insulation blocks takes full advantage of the heat-insulating property of the building wastes such as brick and tile on the one hand, manufacture craft is simple, cost is low, can coordinate with small-sized movable crushing engine, pulverize aggregate at the scene of building waste position and load mould, then transport in precast yard maintenance of being in the milk back, technology is simple, can efficiency of construction be significantly improved on the other hand, reduce building energy consumption, improve bearing capacity and the globality of wall body structure.
