Description

Adjustable flooring steel form support assembly

Technical field

The utility model relates to the structural member of the support shuttering that floor slab construction uses.

Background technology

Multi-storey steel structure and high-rise steel structure development at present is rapid, and flooring primary and secondary beam adopts H shaped steel mostly, and floor support plate is widely adopted.Employed its citation form of various floor support plate is to have the high profiled sheet a direction corrugated shape bending of certain rib now, and its rib height is generally between 50mm～76mm.By use for many years, there is the problem of the following aspects in the floor support plate that the disturbing concrete floor adopts in the discovery prior art:

1. owing to there is the rib height, cause the thickness of composite floor with profiled steel sheet deck bigger, reduced the clear height of floor;

When 2. existing floor support plate adopts both economical thickness of slab, generally need add the interim support of satisfying working load below the floor support plate, thereby increase the workload and the cost of construction, limit construction speed, influence the duration;

3. floor support plate adopts galvanized steel plain sheet to make usually, as penetrating floor support plate, owing to the existence of metallic zinc, can influence the welding quality of peg when the welding peg;

4. existing floor support plate is neither reuses, and becomes permanent structure layer or permanent template after the construction, if as deck, needs mineral wool to handle in the security against fire, and is also uneconomical;

5. in housing construction, existing floor support plate inconvenience is adopted;

6. adopt and now use floor support plate, the Reinforcement Calculation of floor generally can only be by the one-way slabs arrangement of reinforcement, need set up secondary beam when plate is striden greatly, makes troubles sometimes;

7. adjacent straddle is thick not simultaneously, is not easy to construction;

8. floor support plate is limit because of size, and span can not be regulated.

Applicant has proposed " floor slab construction steel form composite member " (application number: patent application 02204600.3) (waiting to announce) can address the above problem preferably before this.If provide than more practical and easy technical scheme, then have more meaning.

Summary of the invention

Technical problem to be solved in the utility model is: reduce floor layer thickness, thereby increase the floor clear height; Need not to add support when smashing floor watering, can convenient construction, improve construction speed; Construction back floor is fixed to have dismountable template after certain rigidity, and cost is saved in recycling; Overcome because of adopting and existing hug board and make the rough phenomenon of soffit; Thick not being convenient to simultaneously of adjacent straddle constructed; The span of construction floor is adjustable.

For addressing the above problem, its special character of the technical solution adopted in the utility model is to be fixed with bearing in the bottom flange of H section steel beam, and this is provided with above bearing and can be arranged with the template joist in the beam-ends cover according to the beam-ends cover of this bearing pivot.

Bearing described in the utility model can be meant: the bottom flange at the H section steel beam is fixed with base, and support is provided with support beam above the base; Described beam-ends cover props up pivotly is located at support beam.

In order to regulate height of support, can respectively be provided with perforation at described support beam two ends and be equipped with studdle in it, studdle lower end weldering knot is fixed in above the described base, and supporting on the studdle have lift adjustment fixedly to use nut.

Can be provided with perforation at described support beam middle part, be fixedly connected with the perforation that bolt is placed through the support beam middle part below beam-ends overlaps, make beam-ends cover support beam pivot and relative fixed relatively.

Base in the utility model adopts steel plate to make, and it is screwed in the bottom flange of described H section steel beam.Support beam can adopt the box steel.

Described template joist can in be placed in the beam-ends cover, so the template joist can adopt C type (box, the H type) steel that is placed in the beam-ends cover on the size in the energy.Put to establish at beam-ends and hold out against screw and template joist relative fixed removably.

Composite member of the present utility model can be symmetricly set in the both sides of described H section steel beam bottom flange one by one, and the template joist is extended to both sides, is suitable for the required flooring construction in both sides.

H section steel beam described in the utility model as the building main beam supporting in pillar.Described template joist is used for laying in the above steel form (also can be wooden form), and template is as watering the bed die of smashing reinforced concrete floor.

The utility model which is provided with the beam-ends cover that can pivot according to bearing owing to be fixed with bearing in H section steel beam bottom flange, be arranged with the template joist in the beam-ends cover, so the template joist can pivot with the beam-ends cover, the template joist of fixed length is got different pivoting angles, just building has different horizontal spans relatively, span of the present utility model thus can be regulated easily, and compliance greatly improves.Lay template on the template joist, template is as watering the bed die of smashing floor, so there is not the rib height that is produced with existing floor support plate in the floor of constructing with the utility model, the floor actual (real) thickness reduced, thus increase floor clear height; The bending rigidity of template joist self is enough to bear the design load on it, so construction the time need not to add interim support, both provides cost savings, again can three-dimensional construction and convenient working, improve work efficiency; Peg can directly weld in girder steel during construction, has solved the problems of welded quality of peg; Construction back floor is fixed when having certain rigidity, can stripping and the utility model in each parts, make it recycling, save cost; Adopt the utility model, the reinforcing bar of floor can adopt cold-rolled ribbed welded wire fabric new technology, and steel mesh reinforcement can be laid by designing requirement, improves floor slab construction speed greatly; The utility model can be avoided the uneven phenomenon of soffit, and making soffit is the plane; Adopt the utility model, adjacent straddle is thick not simultaneously, and it is comparatively convenient to construct.
