Abstract
The invention discloses a kind of profiled sheet concrete bidirectional composite floors of built-in hollow round steel pipe, including profiled sheet, hollow round steel pipe and trussed reinforcing bar network, the profiled sheet, which is fixed on girder steel, serves as lower part template and plate lower part principal rod, in the groove of profiled sheet, hollow round steel pipe is arranged on rib top and groove top, each hollow round steel pipe, which connects to form trussed reinforcing bar network and fix two-by-two by reinforcement welding, becomes an entirety, in the direction arranged for interval plate top distribution bar perpendicular to hollow round steel pipe, bi-directional combination floor is formed in the lateral support template casting concrete of profiled sheet.The built-in hollow round steel pipe bearing capacity of the present invention is big, weight is lighter, thinner, improve floor clear height, reduce cost, truss-like reinforcing bar improves floor shear Capacity, the globality of composite floor and the cohesive force of profiled sheet and concrete are also improved simultaneously, is particularly suitable in the two-way slab of the big load of large span.
Description
Technical field
The invention belongs to technical field of buildings, especially a kind of profiled sheet concrete bidirectional group of built-in hollow round steel pipe
Close floor.
Background technology
Currently, in China's industry and civil buildings, reinforced concrete structure is because raw material are extensive, technology maturation, cost
Cheap is still the architecture structure form being most widely used.But it is built with the raising and modern times of building height and shockproof requirements
The requirement built to floor height, large span, large space is higher and higher, and the application of reinforced concrete structure is made to obtain more limitation.Closely
The development of Nian Lai, reinforced concrete composite structure bring many superiority, more and more in composite structure to use profiled sheet
Concrete combined floor is as floor framing system.Composite deck slabs can be by residing for its each building block
Position and feature give full play to steel tension and the good advantage of concrete anti-compression performance, and with good anti-seismic performance, construction
The technology of performance, composite deck slabs has obtained rapid development.Especially《Composite floor design and construction is advised
Model》(CECS273：2010) issuing and implementation have pushed the development of composite deck slabs significantly.
All there is following some skills for traditional reinforced concrete floor and composite deck slabs system
Art problem：(1) in-situ reinforced concrete slab：Dead weight is too big, is also easy to produce degree of disturbing, crack, need to carry out formwork, form removal construction trouble
And long construction period, there is beam slab to tend not to meet the requirement of building clear height and increases floor height, chainless drives poor seismic behavior
It is also easy to produce degree of disturbing, crack.If especially large-span floor is using above-mentioned form floor and according to existing《Reinforcing bar
Code for design of concrete structures》It will face that plate thickness is too thick if design, dead weight is excessive and is difficult to meet the requirement in crack to ask
Topic.(2) composite deck slabs：Large span composite deck slabs plate thickness is too thick while from great,
The cementitiousness of profiled sheet and concrete is poor, such as document 1 (Zhang Xinying, Shi Qingxuan：Silent section profiled steel sheet combination floor
Longitudinal shear bond bearing capacity is studied,《Sichuan architecture science research》2012,38(02):52-54) pass through verification experimental verification die mould
One of main damage -form of steel plate combination floor destroys for vertical equity shear bond, and pressure will be made by lacking enough cementitiousness
Shape steel plate composite floor loses compound action.
Invention content
That the purpose of the present invention is to provide a kind of bearing capacitys is high, from heavy and light, it is easy for construction built in hollow round steel pipe
Profiled sheet concrete bidirectional composite floor.
Realize that the technical solution of the object of the invention is：A kind of profiled sheet concrete bidirectional of built-in hollow round steel pipe
Composite floor, including profiled sheet, hollow round steel pipe and trussed reinforcing bar network, which, which is fixed on girder steel, serves as lower part
Template and plate lower part principal rod arrange hollow round steel pipe, each open circles on the groove of profiled sheet, rib top and groove top
Steel pipe, which connects to form trussed reinforcing bar network and fix two-by-two by reinforcement welding, becomes an entirety, perpendicular to hollow round steel pipe
Direction arranged for interval plate top distribution bar, form bi-directional combination building in the lateral support template casting concrete of profiled sheet
Plate.
Compared with prior art, the present invention its remarkable advantage：(1) hollow round steel pipe bearing capacity is big built in, in same bearer
Under conditions of power, more common composite deck slabs weight is lighter, thinner, improves floor clear height, reduces
Cost, truss-like reinforcing bar improve floor shear Capacity, while also improving the globality and pressure of composite floor
The cohesive force of shape steel plate and concrete is particularly suitable in the two-way slab of the big load of large span, such as gymnasium, large-scale exhibition
Shop, railway station etc..(2) hollow round steel pipe, profiled sheet can processing factory it is prefabricated, the readily available guarantee of quality, mechanization of building operation
Rate is high.(3) profiled sheet self-supporting serves as lower part template when constructing, easy for construction, shortens the construction period, and saves template.
Present invention is further described in detail below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structural schematic diagram of the profiled sheet concrete bidirectional composite floor of hollow round steel pipe built in the present invention.
Fig. 2 is the sectional view of the present invention.
Specific implementation mode
The profiled sheet concrete bidirectional composite floor of hollow round steel pipe built in the present invention combined with Figure 1 and Figure 2, including pressure
Shape steel plate 2, hollow round steel pipe 3 and trussed reinforcing bar network 4, which, which is fixed on girder steel, serves as lower part template and plate
Lower part principal rod arranges hollow round steel pipe 3, each hollow round steel pipe 3 on the groove 6 of profiled sheet 2, rib top 7 and groove top
It connects to form trussed reinforcing bar network 4 and fix by reinforcement welding two-by-two and becomes an entirety, perpendicular to hollow round steel pipe 3
Direction arranged for interval plate top distribution bar 5 forms bi-directional combination in the lateral support template casting concrete 1 of profiled sheet 2
Floor.
Concrete cover is set on the plate top distribution bar 5 of the present invention.
Embodiment
In conjunction with Fig. 1 Fig. 2, it is first laid with profiled sheet 2 in the construction process, profiled sheet 2, which is fixed on girder steel, serves as lower part
Template and plate lower part principal rod (profiled sheet is placed in the plate bottom), on the groove 6 of profiled sheet 2, rib top 7 and groove
Portion arranges hollow round steel pipe 3, then connects to form trussed reinforcing bar network 4 and fix by reinforcement welding two-by-two by them and becomes one
A entirety, next is in the direction arranged for interval plate top distribution bar 5 perpendicular to hollow round steel pipe 3 and concrete appropriate is stayed to protect
Sheath, finally branch side form casting concrete 1.
