Description
Technical field:
The utility model belongs to building structure technology field, is related to a kind of assembly concrete building, and in particular to a kind of
Novel superposed floor with shear reinforcement.
Background technique:
Currently, applying in Prefabricated stacking floor at most is exactly the laminated floor slab with truss bars, in component production, put
Set the steel bar girder of a certain number of triangles.But the effect of steel bar girder do not play the role of it is great, firstly, root
According to national standard drawings " truss bars concrete folding plate " 15G366-1, the height of steel bar girder when overlapping bottom plate 6cm, last layer 7cm
Degree only has 8cm, and steel bar girder is in the exposed 80mm+23mm of bottom plate (15mm protective layer+8mm longitudinal reinforcement) -60mm=43mm.So
Small steel bar girder height contributes very little to foolrstiffness, and the effect of " increasing rigidity " can be ignored；And steel bar girder is exposed
Seldom, many times constant lifting, simultaneously because steel bar girder is exposed few, spool is difficult easily to pass through in most cases, this makes
Difficulty at construction increases, and indirect improves construction cost.Therefore, what truss bars played the role of is exactly uniquely to construct
Stirrup, but thus will increase the dosage of reinforcing bar, the promotion of cost is undoubtedly caused, it is economical poor.Therefore, design preparation
A kind of novel superposed floor with shear reinforcement can be effectively reduced preparation cost while effectively increasing rigidity.
Utility model content:
Utility model aims to solve drawbacks described above of the existing technology, propose a kind of with shear reinforcement
Novel superposed floor, the floor do not use truss bars, reduce the dosage of reinforcing bar, reduce material cost, while by portion
Longitudinal reinforcement is divided to be made into wave-like, instead of the shearing resistance that original truss bars play a part of, cost does not influence stress also on earth
The purpose of performance.
To achieve the goals above, the utility model relates to a kind of novel superposed floor with shear reinforcement, use with
Under technical solution realize: concrete slab is plane tabular structure, left and right spaced set has N root vertical inside concrete slab
To wave reinforcing bar, N is the integer greater than 2, and the convex portion of longitudinal wave reinforcing bar extends to the upper side of concrete slab, lug boss
Divide and fixed to carry out route in wiring, longitudinally directly reinforcing bar, longitudinal straight steel are provided between adjacent two longitudinal wave reinforcing bars
Muscle is set in concrete slab, and is parallel to the length direction setting of longitudinal wave reinforcing bar, and longitudinal wave reinforcing bar and longitudinal direction are straight
Intensity of the reinforcing bar to improve concrete slab improves anti-shear ability, and going back spaced set in concrete slab has transverse steel, horizontal
It is transversely to the machine direction straight reinforcing bar and longitudinal wave steel-bar arrangement to reinforcing bar, and is set at the groove location of longitudinal wave reinforcing bar,
And weld and connect with the groove of longitudinal wave reinforcing bar, to improve its stability.
Further, the thickness that pours of concrete slab is greater than the straight of longitudinal wave reinforcing bar and transverse steel in the utility model
The sum of diameter, optimal thickness 60mm.
Further, the quantity for the longitudinally directly reinforcing bar being arranged between adjacent two longitudinal wave reinforcing bars in the utility model is excellent
It is selected as 1-3 root, and spaced set, the spacing of any longitudinally directly reinforcing bar and adjacent longitudinally directly reinforcing bar or longitudinal wave reinforcing bar
From equal.
Further, the shape of longitudinal wave reinforcing bar convex portion can choose as semicircle, triangle in the utility model
Shape, rectangle, the shape of a hoof.
Further, the groove of longitudinal wave reinforcing bar is flat-bottom structure in the utility model, in order to transverse steel
Weld together.
The utility model is sequentially placed longitudinal wave reinforcing bar and longitudinally directly reinforcing bar in the preparation, then by transverse steel with
Longitudinal wave steel bar welding connection, then casting concrete are completed preparation, are directly transported when in use to form concrete slab
It carries out to using area using when being routed, directly by line across the convex portion of longitudinal wave reinforcing bar, Lai Jinhang cloth
Line.
Compared with prior art, acquirement has the beneficial effect that the utility model:
1, the dosage of reinforcing bar is reduced, material is reduced instead of original truss bars using the longitudinal wave reinforcing bar in part
Expect cost；
2, longitudinal wave reinforcing bar solves the problems, such as that original truss bars penetration pipe is difficult, exposed waveform reinforcing bar
Hole is larger, and spool facilitates penetration of, and can play the role of shearing resistance, improves construction efficiency.
3, its main structure is simple, and design concept is ingenious, easy to produce and preparation, while preparation cost, application environment friend
It is good, wide market.
