Effect mitigates grate weight.
When being laid with workshop floor, the grate of the concrete column cooperation precasting of precasting can be utilized in appropriate span scope
It is composed, reduces the workload of site operation and achieve the purpose that reduce the construction time.
The combination of grate is as shown in Figure 1.Grate 70,80 sides have connection reinforcing bar 71,81 outstanding, the connection steel
Muscle is again to overlap the connection of reinforcing bar 91.It when being laid with floor is rided upon grate on I-beam 60, then it will be between grate 70,80
Gap concrete perfusion can interconnect grate 70,80 after concrete curing and fixed.
Only the gap of grate 70,80 may be too small, causes to overlap reinforcing bar 91 and links the overlap joint between reinforcing bar 71,81
Distance is too short, thus after being poured concrete, cause bond strength insufficient.Although arranging that the width of more reinforcing bar or increase beam can
With make up overlap distance it is too short caused by intensity deficiency disadvantage, but this two methods can construction to building-site and precasting structure
The manufacture of part brings inconvenience and cost can also improve.To overcome the problems, such as this, also there is the Precasting floor being connected respectively to open up groove
24,34, as Fig. 2 shows.The corresponding section of each Precasting floor is respectively equipped with several connection reinforcing bars 21,22,23 and 31,32,33 and distinguishes
By each 24,34 inside projection in inside of groove.The connection reinforcing bar 21,22,23 and 31,32,33 is to overlap the overlap joint of reinforcing bar 50, then pours
Concrete is infused in intending the gap between combined grate, because of opening up for groove 24,34, make the gap of grate 20,30 compared with
Original wider, the gap is contacted due to linking reinforcing bar and overlap joint reinforcing bar with concrete in casting concrete and after its solidification
Area is bigger, grate connection intensity can thus improve.
It is above-mentioned to open up the problem of still fluted depth of reeded grate is limited to grid plate thickness and deepen, and
And when I-shaped beam width is smaller, grate still has the problem of gap width deficiency, causes the bond strength of grate insufficient,
Therefore, the design of grate has the necessity further improved.
Summary of the invention
It is an object of the invention to overcome the problems, such as that met with grid bond strength is insufficient when being laid with grate on beam.
Usually when being laid with floor, it therefore is that the periphery bottom surface of grate and the top surface of beam connect that grate, which is placed on beam,
Touching, for same strutbeam, the two sides EDGE CONTACT with two panels grate respectively, then, the gap of two grates is by beam
The limitation of width will lead to it and combine rear intensity insufficient when the gap deficiency of two grates.
In the present invention, grate is precast with shearing resistance plate, and the shearing resistance plate is partially protrude through the grate side.
When being laid with grate, contacted with shearing resistance plate with beam, in other words, grate is not contacted with beam directly, then, if two lattice
When needing larger gap between daughter board, it can design or select shearing resistance plate precasting appropriate on grate, make between grate
The intensity that need not be limited by beam width and can have bigger gap, and then combine two grates is more than conventional grate
It is high.
