It is as follows using the making and use process of the detachable reinforcing steel truss floor support plate of the fastener：
1st, will wind up reinforcing bar, web member reinforcing bar and two lower edge reinforcing bars weld, and form steel bar girder；
2nd, according to the specification of bed die, the item number and spacing of setting steel bar girder needed for its upper surface are determined, it is enterprising in bed die
The drilling of row respective numbers and spacing；
3rd, fastener is fixedly connected with the setting that screws of threaded hole by flange screw respectively in bore position；
4th, external force is applied to steel bar girder so that the distance between two lower edge reinforcing bars narrow, and two lower edge reinforcing bars are in junction button
Under the guiding surface one of part and the auxiliary of guiding surface two, into the card slot of connection fastener, then two lower edge steel of steel bar girder
Muscle is arranged in by own resilience in card slot, is repeated aforementioned process, is sequentially completed the consolidating on bed die to every steel bar girder
It is fixed, so as to fulfill the making of detachable reinforcing steel purlin floor support plate；
5th, completion detachable reinforcing steel truss floor support plate is lifted to construction area and carries out concreting, pour completion simultaneously
It after concrete setting to design strength, takes out flange screw and removes bed die, flange screw and bed die can be used for the later stage equal
The use of specification detachable reinforcing steel truss floor support plate.
Wherein, for model TD7-90, (i.e. bar gauge code name is " 7 ", and steel bar girder height is the steel bar girder of 90m
Floor support plate) steel bar truss floor support plate, force analysis using above-mentioned connection fastener and its in the arrangement on bed die calculates such as
Under：
Table one：Main moment under the master data parameter of TD7-90 steel bar truss floor support plates and different mobile loads
In table one, operating mode one is situation of the steel bar girder when construction stage mobile load is uniformly distributed mobile load, and operating mode two is reinforcing bar
Situation of the truss when construction stage mobile load is to concentrate mobile load, as shown in Table 1, the span centre maximal bending moment design value of operating mode one is big
In the span centre maximal bending moment design value of operating mode two, therefore the checking computations such as intensity are carried out to the steel bar truss floor support plate in the case of operating mode one,
Its result is as shown in following table two：
Table two：The intensity of each section and stability numerical value in TD7-90 steel bar truss floor support plates
As shown in Table 2, the stress that reinforcing bar and lower edge reinforcing bar are born at span centre and at bearing that winds up in the case of operating mode one
Value is respectively less than 0.9 times reinforcing bar resistance to compression (drawing) strength failure criterion, therefore intensity expires for the moment in operating mode for wind up reinforcing bar and lower edge reinforcing bar
Foot requirement, meanwhile, the stability value of the reinforcing bar that winds up, lower edge reinforcing bar and web member reinforcing bar is respectively less than reinforcing bar compression strength design value, therefore
Winding up, stability is satisfied by requiring for the moment in operating mode for reinforcing bar, lower edge reinforcing bar and web member reinforcing bar.
In addition, the maximum immunity value of the steel bar girder in the case of operating mode one is 19.49mm, the reinforcing bar purlin in the case of operating mode two
The maximum immunity value of frame is 16.85mm, and the maximum immunity value of bed die is 11.26mm, and relative to deflection limit value, (i.e. bed die calculates
The value of span/180 is 22.22mm) and 20mm in smaller as limit of deflection value, then limit of deflection value is 20mm, from
And understand that operating mode one is respectively less than limit of deflection value with the steel bar girder deflection value in the case of 2 two kinds of operating mode, therefore amount of deflection satisfaction will
It asks.
The embodiment of the utility model is described in detail above, but the content is only the preferable of the utility model
Embodiment, it is impossible to be construed as limiting the scope of the utility model.All impartial changes made according to the scope of the utility model
Change and improvement etc., should all still belong within this patent covering scope.
