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 prominent connection reinforcing bar 71,81, the connection steel
Muscle is connected again with overlapping reinforcing bar 91.It is to ride upon grate on I-beam 60 when being laid with floor, then will be between grate 70,80
Gap concrete perfusion can interconnect grate 70,80 after concrete curing and fixed.
Simply 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 concrete is poured into a mould, causes bond strength insufficient.Although arrange that the width of more reinforcing bar or increase beam can
With make up overlap distance it is too short caused by intensity it is insufficient the shortcomings that, but only this two methods can be to the construction of building-site and pre-
The manufacture of casting component 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
Respectively by each 24,34 inside projection in inside of groove.The connection reinforcing bar 21,22,23 and 31,32,33 is overlapped with overlapping reinforcing bar 50,
Gap of the concrete between the grate of combination is intended is poured into a mould again, because of opening up for groove 24,34, is made between grate 20,30
Gap is relatively original wider, and the gap is in cast concrete and after its curing, due to connection reinforcing bar and overlap joint reinforcing bar and concrete
Contact area 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 smaller, grate still has the problem of gap width is insufficient, causes the bond strength deficiency of grate,
Therefore, grate is designed with the necessity further improved.
Utility model content
The purpose of the utility model is to overcome being met with when being laid with grate on beam, grid bond strength is insufficient to ask
Topic.
Usually when being laid with floor, grate is placed on beam, therefore is that the periphery bottom surface of grate and the top surface of beam connect
It touches, for same strutbeam, the both sides EDGE CONTACT with two panels grate respectively, then, the gap of two grates is subject to beam
The limitation of width when the gap deficiency of two grates, will cause it to combine rear intensity deficiency.
In the utility model, grate is precast with shearing resistance plate, and the shearing resistance plate part protrudes from the grate
Side.When being laid with grate, contacted with shearing resistance plate with beam, in other words, grate does not contact directly with beam, then, such as
When needing larger gap between two grate of fruit, it can design or select appropriate shearing resistance plate precasting to make grid on grate
It need not be limited between plate be subject to beam width and can have the gap of bigger, and then make the lattice of the intensity ratio routine of two grates combination
Daughter board higher.
