Background technique
In recent years, country widelyd popularize assembled architecture, especially assembly concrete and built, shared in newly constructed buildings
Ratio it is higher and higher, assembly concrete building is containing there are many prefabricated components, by predetermined level component and Prefabricated vertical member
Two large divisions's composition.
At this stage, since assembled architecture cost is high, most owner preferentially selects horizontal member prefabricated, answers
It is exactly laminated floor slab at most a kind of prefabricated components, since laminated floor slab production is simple and low in cost, not to structure entirety
Too big stressing influence can be generated, therefore, this component is very widely used, and application can be realized in various structure types.
But this floor is not completely free of the limitation of cast-in-place concrete, it belongs to a kind of superposed member up and down, will
Originally splitted into upper layer and lower layer in floor, lower layer be it is prefabricated, cast-in-place concrete cast in situs is still used on upper layer, and there is no complete in this way
The advantage of assembled architecture is played, scene still can generate a large amount of building waste, and a large amount of concrete must need cast in situs,
Environment is polluted, while noise for generation of constructing etc. can also bring very big influence to local resident.Therefore, this how is solved to ask
Topic, reduces the application and a task of top priority of cast-in-place concrete to the greatest extent.
Utility model content
The purpose of this utility model is to provide a kind of novel full precast floor slab with slope surface, only need to be at the slope surface on four sides
It pours a small amount of concrete to bury reinforcing bar, significantly reduces the amount of pouring of cast-in-place concrete, reduce the generation of building waste,
The good advantage for having played assembled architecture.
The utility model, which is that the following technical solution is employed, to be realized:
A kind of novel full precast floor slab with slope surface, comprising: lower precast floor slab, upper precast floor slab, the lower precast floor slab
Interior lateral, longitudinal Two-way buried end muscle, the bottom muscle run through lower precast floor slab；
Setting is raised in the middle part of the upper precast floor slab, the prefabricated slope in four sides of the protrusion, longitudinal pre- in the protrusion
Longitudinal reinforcement is buried, protrusion, the pre-buried protrusion of the other end and pre-buried length are stretched out less than projection length in one end of the longitudinal reinforcement
1/2；
Lateral service sleeve in the protrusion, the length of the service sleeve are less than the 1/2 of projection length, the pre-buried set
Negative bending moment rib is arranged in pipe；
The lower precast floor slab is located relatively at the outside setting limiting bracket of precast floor slab and the limiting bracket and pre-
Bushing burying is located at the ipsilateral of protrusion, and the limiting bracket includes the pre-buried vertical bar in lower precast floor slab, the height of the vertical bar
Greater than service sleeve height and connect cross bar.
The lower precast floor slab edge and protrusion distance b and slope horizontal length c's and are equal to the full precast floor slab length d
1/6.
The gradient angle with horizontal plane on the slope is 40-60 °.
The upper precast floor slab is identical as the thickness of lower precast floor slab.
The upper precast floor slab, lower precast floor slab are wholely set.
Reinforcing bar is buried the beneficial effects of the utility model are: need to only pour a small amount of concrete at the slope surface on four sides,
The generation for reducing building waste, greatly reduces the amount of pouring of on-site concrete, reduces the influence to ambient enviroment, mention simultaneously
High globality of the floor with seat structure.
