Description
Technical field
This utility model relates to building field, particularly relates to a kind of full assembled steel-concrete Tulou
Plate combination beam.
Background technology
Steel-concrete composite beam is that the one grown up on the basis of steel construction and xoncrete structure is new
Type structural shape.It mainly by arrange between girder steel and concrete floor shear connector (peg,
Channel-section steel, curved muscle etc.), both starting and Relative sliding at interface of opposing, make one
Overall and cooperation.
At present, conventional steel-concrete composite beam is steel-cast-in-place concrete floor combination beam and steel-overlapping
Integral concrete floor combination beam.
Steel-cast-in-place concrete floor combination beam is made up of girder steel, cast-in-place concrete floor and shear stud,
There is the advantages such as integral rigidity is big, compound action is notable, be applicable to the flooring that horizontal layout is complicated.
But having the disadvantage in that 1. wet trade amount is very big, causes efficiency of construction low, cost is high and pollutes environment；
2. template is many with on-the-spot support, reduce further efficiency of construction, improves cost；3. girder steel is with existing
Pouring concrete floor is i.e. integrated after pouring, it is impossible to dismounting, causes the load of floor at existing structure
During increase, it is impossible to change thick floor, when floor damages, it is impossible to the floor more renewed, and floor
Can not recycle, be not suitable for building industrialization.
Steel-overlapping integral concrete floor combination beam by girder steel, overlapping integral concrete floor and
Shear stud forms, and has the advantages such as integral rigidity is big, compound action is notable equally, and scene is saved
Save template and portion support, carried compared to steel-cast-in-place concrete floor combination beam efficiency of construction
High.But still Shortcomings, it is mainly manifested in: 1. scene remains a need for casting concrete and realizes combination
Effect, wet trade is more, causes efficiency of construction low, and cost is high and pollutes environment；2. profiled sheet
Concrete combined floor and steel bar girder concrete combined floor need to install support, plate when span is bigger
The end, need to prevent fires and preservative treatment, relatively costly；Prestressed concrete overlapped slab (flat board) and reinforcing bar
Truss concrete folding plate need to install support when span is more than 1.8m, and prestressed concrete with ribbing is folded
Plywood need to install support when span is more than 3.6m, reduce further efficiency of construction, improves into
This；3. girder steel and overlapping integral concrete floor are i.e. integrated after pouring, it is impossible to dismounting, cause
When the load of floor of existing structure increases, it is impossible to change thick floor, when floor damages, it is impossible to more
The floor renewed, and floor can not recycle, and is not suitable for building industrialization.

The demand in face, is connected by tongue and groove mode between prefabricated concrete floor.If desired, can be along prefabricated mixed
Solidifying Tulou plate is laterally applied to horizontal prestressing force, and between increase prefabricated concrete floor, the occlusion at tongue and groove is strong
Degree and frictional force.
Above-mentioned introduction is J-type fixture and situation that T-shaped securing member is 1, J-type fixture and T-shaped
Securing member can be two, as shown in Figure 6, lays respectively at the both sides of girder steel top flange, increases pressure
Power and frictional force, install more firm.
In order to meet the intensity of all parts, the material of J-type fixture is common iron or high-strength steel, T
Type securing member material is steel.
On the other hand, this utility model provides a kind of above-mentioned full assembled steel-prefabricated concrete floor group
Closing the installation method of beam, one of them embodiment includes:
Step 1: install girder steel；Concrete, install H profile steel beam, T-steel beam, steel beam with box shape or
The girder steel (containing overhanging top flange) of other cross section type, wherein top flange is above web.
Step 2: prefabricated concrete floor is shelved on girder steel top flange upper surface.
Step 3: the fastening screw of T-shaped securing member is screwed in the sleeve of J-type fixture from top to bottom,
And adjust its height to correct position.
Step 4: the top cap of J-type fixture is stretched into (preferably C in the guide groove in prefabricated concrete floor
Shaped steel guide groove), then half-twist.
Step 5: upwards tightened by T-shaped securing member, makes the lower surface of friction steel plate and girder steel top flange
Fit tightly, and produce reliable frictional force.
Further, when T-shaped securing member includes ball pivot and circular hole, originally it is preferably a step: by spanner
Inserting circular hole, rotary spanner, upwards tightened by fastening screw, period constantly adjusts ball pivot and friction steel
Plate, makes friction steel plate fit tightly with the lower surface of girder steel top flange, and produces reliable frictional force,
Become an entirety.
Further, when T-shaped securing member includes nut, also include step 6: by nut under
Up it is screwed into fastening screw, and tightens.
The installation method of this utility model embodiment has the advantage that
1. without poured in place concrete wet trade so that efficiency of construction is high, decreases cost, and
Do not pollute the environment.
2., without template and on-the-spot support, further increase efficiency of construction, reduce cost.
3. have only to be screwed in sleeve fastening screw during construction, and top cap is stretched in guide groove, finally
Tighten fastening screw, otherwise during dismounting so that install quick with convenient disassembly, and to installation
Required precision the highest.
4. and owing to girder steel and prefabricated concrete floor are detachable so that the load of floor of existing structure
During increase, the floor of thickness can be changed, when floor damages, the floor that can more renew, and floor
Can recycle, it is achieved that building industrialization.
5. this utility model embodiment firmly installs, superior performance.
The above is preferred implementation of the present utility model, it is noted that for the art
Those of ordinary skill for, on the premise of without departing from principle described in the utility model, it is also possible to make
Going out some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
