DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0015] A support device for the construction of a steel structure floor, including a supporting plate 1. At each of the four corners of the bottom of the supporting plate 1, a connecting rod 2 is provided. A "U"-shaped fixing frame 3 is provided at the lower part of the connecting rod 2. A screw hole 4 is provided on each side of the fixing frame 3. The screw hole 4 can be threadedly connected to a clamping bolt 5. A rubber plate is provided at one end of the clamping bolt 5 located inside the fixing frame 3, so as to increase the stability of the clamping fit between the clamping bolt 5 and the steel beam or steel column. The present utility model plays a supporting role in the welding of the steel structure floor through the supporting plate 1. At the same time, through the fixing frame 3 and the clamping bolt 5, it can be fixedly connected to steel beams or steel columns of different sizes, so that the supporting plate 1 and the connecting rod 2 can stably play a supporting role in the welding of the steel structure floor.

[0016] Specifically, the connecting rod 2 described in this embodiment is a telescopic rod structure. The connecting rod 2 of the telescopic rod structure can adjust the position of the support plate 1 according to the placement position of the steel structure floor, thereby achieving stable support for the steel structure floor.

[0017] Specifically, two slide grooves 6 are provided at the bottom of the support plate 1 described in this embodiment, and two sliders 7 are arranged at both ends of the slide groove 6. The slider 7 is fixedly connected to the top of the connecting rod 2. A through groove 8 is provided at the bottom of the slide groove 6, and the connecting rod 2 can pass through the through groove 8, and the slider 7 cannot pass through the through groove 8. A screw rod 9 is provided in the slide groove 6, and both ends of the screw rod 9 are rotatably connected to the two ends of the slide groove through bearings 10 respectively. A rotating sleeve 11 is provided in the middle of the screw rod 9, and the rotating sleeve 11 is used as a dividing point to divide the screw rod 9 into two sections with opposite thread directions. A screw groove 12 is provided in the slider 7, and the screw 9 can be threadedly connected to the screw groove 12. By rotating the rotating sleeve 11, the screw rod 9, the slider 7 and the connecting rod 2 can be moved, and since the two sections of the screw rod 9 have opposite thread directions, the slider 7 and the connecting rod 2 can move toward or away from each other, thereby conveniently realizing the movement and fixation of the connecting rod 2, so that the position of the connecting rod 2 can be conveniently adjusted according to the position of the nearby steel beams and steel columns, so that the fixing frame 3 can be more conveniently fixedly connected to the nearby steel beams or steel columns through the clamping bolts 5.

[0018] Furthermore, a universal ball joint 13 is provided between the fixing frame 3 and the connecting rod 2 in this embodiment. The universal ball joint 13 can drive the fixing frame 3 to rotate at multiple angles, thereby facilitating the fixing frame 3 to be fixedly connected to a nearby steel beam or steel column through the clamping bolt 5.

[0019] Furthermore, the support plate 1 described in this embodiment is provided with a plurality of rubber protrusions 14 on the top. The protrusions 14 can increase the friction between the support plate 1 and the steel structure floor, thereby further improving the stability during support.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
