Description
Technical field
The utility model belongs to engineering structure technical field, and in particular to a kind of prefabricated assembled composite floor.
Background technology
Assembling type steel structure system has that construction quality is light compared with traditional reinforced concrete structure, environmental protection, construction speed
The advantages that degree is fast, industrialization degree is high, can better adapt to the development of China's building trade.Composite floor is as a kind of new knot
Configuration formula, girder steel is linked together with concrete floor using shearing-resistant member, form combining structure, two kinds of materials can be given full play to
The mechanical property of material, reduce fine strain of millet height, increase building uses space, in addition, this combining structure has more preferable Hysteresis Behavior, becomes
Shape performance is more preferable than normal concrete structure, has very big advantage when resisting earthquake load.Cause beam slab in composite floor
Compound action can be played is the shearing-resistant member for connecting beam slab, present shearing-resistant member be typically connected by screw bolts, it is necessary in girder steel and
Perforate on concrete slab, scene needs to complete device to hole, wears the construction technologies such as bolt, anchoring, so as to cause site construction technology non-
Often complicated, speed of application is slow.Therefore, seek that a kind of anti-seismic performance is good, easy for construction, energy-conserving and environment-protective, recoverable it is new
Prefabricated assembled composite floor, it is very important so as to give full play to the advantage of fabricated construction.
The content of the invention
The shortcomings that in order to overcome above-mentioned prior art, the purpose of this utility model are the provision of a kind of prefabricated assembled group
Floor is closed, manufacture craft is simple, easy for construction.
In order to achieve the above object, the utility model adopts the technical scheme that：
A kind of prefabricated assembled composite floor, including more than two precast slabs 5, adjacent precast slab
5 are welded together by angle steel 3 pre-buried in precast slab 5 using butt weld 6；In each precast slab 5
Shear amchor bolt 4 is connected with pre-buried angle steel 3, and is connected by shear amchor bolt 4 and girder steel 1.
On the described edge of a wing of girder steel 1 reserve hole 2, and the angle steel 3 of the position correspondence of hole 2 reserving hole be welded with it is anti-
Cut crab-bolt 4.
Hole 2 is being reserved on the symmetrical position of web in the described top flange of girder steel 1.
Compared with prior art, advantage of the present utility model is embodied in：
1st, the utility model uses prefabricated assembled composite floor, and all components are completed in factory process, and transport is to applying
Behind work building site, can assembly connection at the construction field (site), reduce Site Welding work and last engineering, ensure that site operation matter
Amount, improves building industrialization efficiency of assembling.
2nd, the utility model is attached by being embedded in the shear amchor bolt 4 of precast slab 5 with girder steel 1, and conventional
Bolt connection compare, the nut on the inside of steel beam flange need to be only tightened during construction, it is easy for construction.
3rd, angle steel 3 pre-buried in the utility model precast slab 5 can effectively fix the position of shear amchor bolt 4,
Improve the producing efficiency of precast slab.And it can prevent precast slab 5 from being contacted with the direct of girder steel 1, in order to avoid lead
The stress raisers of precast slab 5 are caused, crush concrete.
Brief description of the drawings
Fig. 1 is side view of the present utility model.
Fig. 2 is stereogram of the present utility model.
Fig. 3 is the drawing of angle steel 3.
Embodiment
Make narration in detail to the utility model below in conjunction with the accompanying drawings.
Reference picture 1, Fig. 2 and Fig. 3, a kind of prefabricated assembled composite floor, including more than two precast slabs 5,
Adjacent precast slab 5 is welded together by angle steel 3 pre-buried in precast slab 5 using butt weld 6, is improved
Structure amount globality；Shear amchor bolt 4 is connected with each precast slab 5 on pre-buried angle steel 3, and passes through shearing resistance anchor
Bolt 4 and girder steel 1 connect.
On the described edge of a wing of girder steel 1 reserve hole 2, and the angle steel 3 of the position correspondence of hole 2 reserving hole be welded with it is anti-
Cut crab-bolt 4.
Hole 2 is being reserved on the symmetrical position of web in the described top flange of girder steel 1.
Be prefabricated in the factory the stage when, first will be when processing girder steel 1, reserving hole 2；When processing angle steel 3, itself and girder steel
Position reserving hole corresponding to hole 2 on 1；Again by the reserving hole of the inserted angle steel 3 of shear amchor bolt 4, and welded with it；Make
During precast slab 5, angle steel 3 is put in corresponding position in template, then casting concrete, vibrated, conserved, completed prefabricated mixed
The making of concrete board 5, now angle steel 3 and shear amchor bolt 4 have been embedded in precast slab 5 and suffered.
When constructing at the construction field (site), after girder steel 1 is installed, by the pre-buried shear amchor bolt 4 and steel of precast slab 5
The reserved hole 2 in the top flange of beam 1 aligns, and is installed in hole 2, and is fixed with nut, forms an anchorage effect, now
Precast slab 5 is installed on the top of girder steel 1.After treating the integral installation of precast slab 5, by two blocks of precast concretes
Adjacent pre-buried angle steel 3 is welded together using butt weld 6 on plate 5.
