[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See below Figure 1 to Figure 4 The low-cost and convenient steel deck support device of the utility model is described in detail.

[0027] The low-cost and convenient steel deck support device of the utility model comprises a steel deck 1, a structural I-beam 2, a wooden plank 3, a steel deck vertical support member 4 and a supporting crossbeam 5. The steel deck 1 is placed on the upper surface of the upper flange of the structural I-beam 2. At the same time, in order to prevent the steel deck 1 from collapsing in the middle and deflecting too much due to the large span, the steel deck 1 is supported in the transverse span direction by two full-length wooden planks 3. The wooden planks 3 are located at the bottom of the steel deck 1 and are arranged parallel to the length direction of the structural I-beam 2. The wooden planks 3 are placed on the steel deck vertical support member 4. The steel deck vertical support member 4 can adjust its own height according to the cross-section of the structural I-beam 2 of different heights, and then adjust the height of the wooden planks 3 to support the middle of the steel deck 1. The steel decking plate vertical support member 4 is supported by a supporting crossbeam 5, which is arranged perpendicularly to the length direction of the structural I-beam 2 and is placed on the upper surface of the lower flange of the two structural I-beams 2, so that the load on the steel decking plate 1 can be effectively transferred to the structural I-beam 2.

[0028] like Figure 1 As shown, the two ends of a steel deck 1 are supported by two structural I-beams 2, and in order to prevent the middle of the large-span steel deck 1 from collapsing or deflecting too much, the mid-span portion of the steel deck 1 is supported by two full-length wooden beams 3. Two wooden beams 3 are arranged along the transverse direction (width direction) of the steel deck 1, and the length of the wooden beams 3 along the length direction of the structural I-beams 2 is the same as the longitudinal direction (length direction) of the steel deck 1, and the wooden beams 3 are placed on the vertical support members 4 of the steel deck.

[0029] like Figure 2 , 4 As shown, the steel deck vertical support member 4 is composed of a wood receiving slot plate 41, a bearing structure 42, a circular adjustment structure 43, an adjustment screw 44, a fixed round tube 45, a round tube bottom plate 46 and a stiffening plate 47. The wood receiving slot plate 41, the bearing structure 42, the adjustment screw 44, the fixed round tube 45 and the round tube bottom plate 46 are arranged in sequence from top to bottom. The wood receiving slot plate 41 has a groove that is adapted to the wood 3 and is used to place the wood 3. The groove of the wood receiving slot plate 41 contacts the wood 3, thereby realizing the effective downward transmission of the load of the steel deck 1.

[0030] like Figure 4 As shown, the bearing structure 42 is divided into an inner ring and an outer ring. The outer ring of the bearing structure 42 is connected to the wooden receiving groove plate 41 by welding, and the inner ring is fixedly connected to the top of the adjusting screw 44. The top of the adjusting screw 44 can also be fixed to the inner ring of the bearing structure 42 by interference fit, so that the wooden receiving groove plate 41 is not affected when the adjusting screw 44 is rotated.

[0031] In addition, the circular adjustment structure 43 is fixed on the adjustment screw 44, and is provided with a structure that is easy to hold by hand to facilitate rotation with force, and is spot-welded to the adjustment screw 44 to form a whole, thereby enabling the support height of the entire steel deck vertical support member 4 to be controlled according to the different heights of the structural I-beam 2.

[0032] The interior of the fixed circular tube 45 is provided with a threaded hole threadedly connected to the adjusting screw 44, and the adjusting screw 44 can be rotated to achieve up and down adjustment. The circular tube bottom plate 46 is fixed to the bottom end of the fixed circular tube 45 and is located in the supporting crossbeam 5. Between the circular tube bottom plate 46 and the fixed circular tube 45, there are stiffening plates 47 evenly distributed around the fixed circular tube 45. The circular tube bottom plate 46 and the stiffening plates 47 form the base structure of the entire steel deck vertical support member 4, and both are spot-welded to the fixed circular tube 45.

[0033] like Figure 2 , 3 As shown, the supporting cross beam 5 is a channel steel, which is arranged between two structural I-beams 2 and is spot-welded to the structural I-beams 2 and the round tube bottom plate 46 in the steel decking vertical support member 4.

[0034] In a specific embodiment, the number of supporting beams 5 is at least three, and they are evenly distributed along the length direction of the structural I-beam 2; the number of wooden squares 3 is at least two, and they are evenly distributed along the width direction of the steel deck 1; the number of steel deck vertical support members 4 is multiple, and they are evenly spaced along the length direction of each supporting beam 5.

[0035] The utility model provides a low-cost and convenient installation method for a steel deck support device: first, a plurality of support beams 5 are evenly spaced on the structural I-beam 2, and vertical support members 4 of the steel deck are arranged on the support beams 5. Then, wooden squares 3 are placed on the vertical support members 4 of the steel deck to support the steel deck 1 to prevent the middle part from collapsing or deflecting too much, thereby causing a safety hazard.

[0036] A steel decking plate 1 is laid on the upper surface of the upper flange of the structural I-beam 2, and two full-length wooden squares 3 are added to the bottom of the steel decking plate 1 for support; a supporting crossbeam 5 is provided on the upper surface of the lower flange of the structural I-beam 1, and the supporting crossbeam 5 is used to place the vertical support members 4 of the steel decking plate. The vertical support members 4 of the steel decking plate receive the two full-length wooden squares 3, which can effectively transfer the load of the steel decking plate 1 to the supporting crossbeam 5, thereby avoiding problems such as middle collapse and excessive deflection of the large-span steel decking plate 1.

[0037] The utility model solves the problems of inconvenient installation of steel deck support during the construction of steel structure floor deck, excessive material consumption, inconvenient disassembly, high cost and inapplicability to structural I-beams of different heights through a simple, reasonable, low-cost and convenient steel deck support device. The utility model can effectively transfer the concrete floor load on the steel deck 1 to the structural I-beam 2 through the wooden square 3, the steel deck vertical support 4 and the supporting crossbeam 5, and can effectively prevent the middle of the steel deck 1 from collapsing or deflecting too much; it can also be applied to structural I-beam floor deck supports of different heights by adjusting the height supported by the steel deck vertical support 4. The device is suitable for supporting steel beam floor decks 2 of different heights, and can effectively reduce the risks caused by too high a support height. It has a simple structure, greatly improves work efficiency and reduces construction costs.

[0038] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be understood by anyone familiar with the technology within the technical scope disclosed by the present invention should be included in the scope of the present invention.
