Description
Technical field
The present invention relates to a kind of structural system of building bearing structural system, particularly a kind of concrete building block post.
Background technology
China completely forbids and uses the time limit of loam brick to have arrived, and for without loam brick and building energy conservation, has occurred the various bodies of wall that a hundred flowers blossom at present.For example:
1, compressed straw slab exterior wall adopts the light steel square steel pipe of thin-walled of wall thickness 2mm, 60 * 60mm to do load-bearing pillar, and spacing 0.6m, its anti-bending bearing capacity only are the 0.138t-m/ root.And if this ground wind reference pressure is 0.5KN/m2,3m height then, 2.4m the moment of flexure value that the light steel square steel of the thin-walled on window limit post bears is about the 0.49t-m/ root, its anti-bending bearing capacity only is 28% of the moment of flexure value of bearing, and promptly the light steel square steel of thin-walled post does not satisfy the anti-bending bearing capacity of design.The moment of flexure value that the light steel square steel of the thin-walled of spacing 0.6m post bears is about the 0.29t-m/ root.Only be to bear 48% of moment of flexure value, also do not satisfy the anti-bending bearing capacity of design.
The light steel square steel of thin-walled post pole is perishable, particularly faster in root run place corrosion, in general local-style dwelling houses, can not on the light steel square steel pipe of thin-walled, brush high erosion shield, when brushing general corrosion resistant coating, it is very limited to increase the corrosion-resistant time limit, and dangerous generation has been quickened in the corrosion of steel column.
There is potential safety hazard in this compressed straw slab exterior wall.
2, the light steel square steel pipe of the thin-walled of also useful wall thickness 3mm, 100 * 100mm is done load-bearing pillar, and spacing 4m is installed in the exterior wall of the light steel square steel pipe of thin-walled both sides after compound with benzene plate and cement fibrolite plate.The light steel square steel of the thin-walled of this specification post anti-bending bearing capacity is the 0.58t-m/ root.And if this ground wind reference pressure is 0.5KN/m2, then 4mi spacing, the light steel square steel of thin-walled post that 3m the is high moment of flexure value of bearing is about the 1.288t-m/ root.The anti-bending bearing capacity of the light steel square steel of this thin-walled post only is to bear 45% of moment of flexure value, does not also satisfy the anti-bending bearing capacity requirement of design.
The problem that equally also has corrosion.
Common private residence can not be coated with the very thick fire resisting paint of brush applied coating on the light steel column of thin-walled, the fireproof performance of the light steel column of thin-walled is bad,
3, the light wall that also has so-called lattice, the light wall rigidity of lattice is poor, does not also satisfy the requirement that structure design is subjected to curved bearing capacity.
The light wall of so-called lattice is in the middle of the benzene plate, and it is the level of 80～100mm and vertical concrete rod---small column and straining beam that diameter is set at a certain distance, and 1 reinforcing bar is arranged in concrete small column or the straining beam.Owing to work hardly to bending resistance in the neutral axis position that stressed concrete small column or straining beam are positioned at the flexural member body of wall.This body of wall rigidity is too poor, if there has not been the benzene plate, the small column of these lattices or straining beam can not be stood upright.
Therefore, the light wall of so-called lattice is to satisfy the requirement that structure design is subjected to curved bearing capacity.
Above-mentioned phenomenon explanation: in the current new countryside construction, there is potential safety hazard in agricultural Housing construction.
Though if, need a template, tie up reinforcing bar, fluid concrete, the cost height with cast-in-situ concrete frame construction safety.Because of frame construction cost height, the general civilian construction multi-story masonry structural construction in city all is unwilling to adopt the cast-in-situ concrete frame construction, and the small building in rural area adopts frame construction more to highlight the cost height so, the problem of construction inconvenience.
Above-mentioned phenomenon also illustrates: do not have a kind of cost lower at present, easy construction, satisfy safety requirements, can the instead of clay brick, be fit to the structural system of single load-bearing, particularly this structural system should conveniently be installed straw, light block, and the macromolecule heat insulating material is as the exterior wall of filling, the energy-saving heat preserving effect of performance heat insulating material, the requirement that adapts to building energy conservation and utilize refuse.
In addition, in two, three layers low-rise building during without loam brick, need also to provide that a kind of cost is lower, the exterior wall bearing structural system of easy construction, safety, same this structural system should conveniently be installed straw, light block, the macromolecule heat insulating material is as the exterior wall of filling, the energy-saving heat preserving effect of performance heat insulating material, the requirement that adapts to building energy conservation and utilize refuse.
