Description

Adopt the precast concrete laminated floor slab of bolt and the syndeton of H profile steel beam
Technical field:
The utility model relates to building structure connector technical field, is specifically related to a kind ofly adopt the precast concrete laminated floor slab of bolt and the syndeton of H profile steel beam.
Background technology:
Assembling type steel structure building is promoting the fast development of building industry, and because of advantages such as it is easy for installation, resource reproducible utilizations, being described as is a kind of building structure pattern of environmental protection, is the research direction that China will realize industrialized development from now on.
Assembling type steel structure house then has the following advantages: 1. steel work energy-conserving and environment-protective.The recyclable recycling of steel; 2. anti-seismic performance is good.Steel work high-strength light, can effectively reduce geological process power; 3. industrialization degree is high.Steel work major part component has been produced in factory, is beneficial to and realizes the demand for development of China to industrialized building; 4. construction pollution is little.All prefabricated in factory completing produced by component, on-site hoisting, connection; 5. space flexible arrangement is convenient.
Precast concrete laminated floor slab is one of main floor form of current assembling type steel structure building research, it has good globality, crack resistance, shock resistance and thermal and insulating performance, site operation is easy, the duration shortens, without the need to formwork, save the advantage such as material, mechanization production, makes this floor system obtain investigation and application more widely.Between current precast concrete laminated floor slab and girder steel, the most frequently used type of attachment has this three class of peg, shaped steel and curved muscle:
Peg shear connector, manufacturing process is simple, is convenient to Site Welding, is most widely used at present.Its stress performance is: when load action, peg moves together with girder steel, external load passes to the root of peg by peg weld seam, and produce larger distortion, whole peg will be subject to the synergy of moment of flexure, shearing and pulling force, due to this effect, makes peg root bear pressure maximum, along reducing highly gradually, the pressure reversal of bearing when top close to peg.Therefore the normal mode of failure occurred is, the concrete local compression fragmentation of peg front root or splitting, thus causes integrally-built destruction.
Shaped steel shear connector shear resistance is strong, and the performance of distribution again shearing is good, and can play opposing lifts role simultaneously on the edge of a wing.But Site Welding workload is large, construction speed is slow, and steel using amount is larger.
Curved muscle shear connector, uses comparatively early, makes and constructs all simpler.But due to can only utilize curved muscle tensile strength opposing shearing, therefore in shearing direction indefinite or shearing direction may change time, action effect is poor.
Above-mentioned several connector all needs to carry out on-the-spot welding job, and steel-concrete connected mode is also Site Welding in building operations, not only construction speed is slow, bonding strength is poor, steel using amount is comparatively large, therefore, needs to provide a kind of new Joining Structure, avoid carrying out Site Welding work, really realize overall fabricated construction.
Utility model content:
The purpose of this utility model is to provide a kind ofly optimizes the precast concrete laminated floor slab of the employing bolt of precast concrete laminated floor slab and girder steel switching performance in steel building and the syndeton of H profile steel beam.
For achieving the above object, the utility model is by the following technical solutions:
The precast concrete laminated floor slab of the employing bolt that the utility model provides and the syndeton of H profile steel beam, comprising: H profile steel beam, prefabricated plate, layer of concrete, bolt and nut; Described prefabricated plate is overlapped on the edge of a wing place of H profile steel beam, described H profile steel beam offers the first through hole, described prefabricated plate offers the second through hole with described first through hole correspondence position, prefabricated plate is fixed in described H profile steel beam through described first through hole and the second through hole by bolt, bolt is stretched out prefabricated plate one end and is locked by nut, and layer of concrete has been built in prefabricated plate periphery.
The length at the first through hole distance upper limb edge that described H profile steel beam is offered is more than or equal to 25mm.
The length of the second through hole distance sheet edges that described prefabricated plate is offered is more than or equal to 20mm.
The thickness of described prefabricated plate is 50-80mm.
The equal diameters of described bolt, the first through hole and the second through hole, diameter is 10-20mm.
The length of described bolt is more than or equal to 1.5 times of prefabricated plate thickness.
It is two right that described bolt and nut are at least.
The utility model adopts the beneficial effect of the precast concrete laminated floor slab of bolt and the syndeton of H profile steel beam: structural form is simple, be easy to realize standardization, modularization is produced, site assembly is easy, construction accurate positioning, thus greatly save the set-up time, improve engineering efficiency; Adopt the syndeton of bolt, do not affect concrete building, ensure that and connect closely between girder steel and precast concrete laminated floor slab, the overall performance of structure is improved; And scene is without the need to welding, assembling is simple, easy construction, and is arranged by rational design consideration construction specific requirement, greatly can simplify construction process; Agent structure distortion can either be adapted to preferably, ensure to connect safe and reliable, again can saving steel, be easy to construction and realize industrialization produce.
