Detailed Description

The following template bearing structure of the prefabricated reinforced concrete integral casting structure floor discharge pit of the warehouse of the utility model is described in further detail with reference to the accompanying drawings and specific examples, but the examples should not be construed as limiting the utility model:

as shown in fig. 1 to 4, the formwork support structure at the discharge pit of the floor of the prefabricated reinforced concrete integral casting structure of the warehouse comprises two fixtures 1, two main beams 4, two brick piers 6 and a plurality of steel pipes 5.

Each fixture 1 is a main force transmission component and a bearing component, and comprises a jackscrew 1.1 for elevation adjustment, a sleeve 1.2, a screw rod 1.3, a nut 1.4, a cross beam 1.5 and two parallel vertical beams 1.6. The upper ends of the two vertical beams 1.6 are connected with the cross beam 1.5 to form an inverted U-shaped structure and are clamped on the two layers of precast beams 7. The sizing block 2 is put on the cement face that two layers of precast beam 7 correspond to crossbeam 1.5, crossbeam 1.5 is equipped with the pinhole, sleeve 1.2 welding is in pinhole department (the sleeve center aligns with the pinhole center), jackscrew 1.1 passes sleeve 1.2 and pinhole and sizing block 2 offset from last to down in proper order, adjusts the top elevation of girder 4 through rotatory jackscrew 1.1, the elevation adjustment back of finishing, the intermediate space of fixture 1 and two layers of precast beam is filled up with the sizing block 3 and is real. The lead screw 1.3 is connected with the two vertical beams 1.6 to balance and stabilize the fixture 1, specifically, holes for the lead screw 1.3 to vertically pass through are formed in the lower portions of the two vertical beams 1.6, and the lead screw 1.3 passes through the lower portion of the two-layer precast beam 7 and is fixed through the nut 1.4.

One side web plate of each vertical beam 1.6 facing the loading platform 8 is provided with an opening supporting plate 1.7 and a ribbed plate 1.8 for supporting the opening supporting plate 1.7.
