Edge closing structure of fabricated steel structure floor support plate

Abstract

The utility model discloses an edge closing structure of an assembly type steel structure floor support plate. The edge closing structure comprises a steel beam for supporting a bottom formwork; the bottom template is used for placing the profiled galvanized sheet and is fixedly mounted on the top surface of the steel beam; the wave-shaped profiled galvanized sheet is mounted on the upper top surface of the bottom template; limiting nails used for making contact with and abutting against the side edges of the profiled galvanized sheet are vertically fixed to the steel beams. The limiting nails vertically fixed to the steel beam make contact with and abut against the side edge of the profiled galvanized sheet for limiting, when an operator steps on the profiled galvanized sheet downwards, the profiled galvanized sheet deforms downwards and makes contact with the abutting pieces on the limiting nails all the time for continuous limiting, meanwhile, the limiting nails vertically fixed to the steel beam are fixed and cannot be damaged when the operator steps on the profiled galvanized sheet downwards, and the safety of the operator is guaranteed. The problem that the horizontal connecting rod loses the limiting function due to the fact that a welding point of the horizontal connecting rod and the profiled galvanized sheet is located on the horizontal plane and is prone to being damaged when the profiled galvanized sheet elastically deforms and displaces downwards is solved.

Description

Technical Field

[0001] The utility model relates to an edge trimming structure of an assembled steel structure floor deck, belonging to the technical field of building construction. Background Art

[0002] When constructing a prefabricated steel structure factory building, before installing the phosphogypsum vertical wall panels in the office area, it is necessary to first cast the floor slab to form the floor deck. In order to reduce the overall weight of the floor slab, first install an I-shaped steel beam on the vertical column of the steel structure, lay a thin bottom template 12 on the steel beam 11, and lay a wavy corrugated galvanized sheet 13 on the bottom template 12 for connection, such as Figure 3 As shown, the reinforcement is then tied on the profiled galvanized sheet 13 and concrete is poured to form the floor deck.

[0003] After the corrugated galvanized sheet 13 is installed on the bottom template 12, the side of the corrugated galvanized sheet 13 needs to be limited to ensure the stability of deformation when the operator steps on it. The existing side limit technology is to limit the side template by installing a horizontal connecting rod (see Chinese patent announcement No. CN209568593U, the horizontal connecting rod is in a horizontal state and is supported by the side template). When the operator steps on the corrugated galvanized sheet and elastically deforms downward, the welding point 15 of the horizontal connecting rod 14 and the corrugated galvanized sheet is horizontal. Figure 3 As shown, the welding points of the corrugated galvanized sheet metal are easily damaged due to the downward elastic deformation, causing the horizontal connecting rod to lose its limiting function. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an edge finishing structure of an assembled steel structure floor deck.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides an edge trimming structure of an assembled steel structure floor deck, comprising:

[0007] Steel beams supporting the bottom formwork;

[0008] The bottom formwork is used to place the pressed galvanized sheet, and the bottom formwork is fixedly installed on the top surface of the steel beam;

[0009] The corrugated galvanized sheet is installed on the top surface of the bottom template;

[0010] Limiting nails for contacting and resisting the side edges of the corrugated galvanized sheet are vertically fixed on the steel beam.

[0011] The steel beam between the side formwork and the corrugated galvanized sheet is exposed, and a vertical limiting nail is screwed on the exposed steel beam through a threaded pair.

[0012] The limiting nail is sleeved with a stopper contacting the profiled galvanized sheet, and the stopper is pressed and fixed on the steel beam by the limiting nail.

[0013] The side surface of the stopper contacting the profiled galvanized sheet is an inclined surface or a straight surface.

[0014] The corrugated galvanized sheet is provided with ribs, and the ends of the ribs are in contact with the stoppers.

[0015] The corrugated galvanized sheet contains concrete, and the ribs are inside the concrete.

[0016] There are multiple corrugated galvanized sheets, and the multiple corrugated galvanized sheets overlap at the joints.

[0017] The steel beam is composed of an I-beam.

[0018] The beneficial effects of the utility model are as follows: the limit nails vertically fixed on the steel beam contact and resist the side of the corrugated galvanized sheet to limit the position, and when the operator steps on the corrugated galvanized sheet, the corrugated galvanized sheet is deformed downward and always contacts and limits the position with the stopper on the limit nails, and at the same time, the limit nails vertically fixed on the steel beam will not be damaged when the downward force is applied, thus solving the problem that the welding point between the horizontal connecting rod and the corrugated galvanized sheet is horizontal, and the welding point is easily damaged when the corrugated galvanized sheet is elastically deformed and displaced downward, causing the horizontal connecting rod to lose its limiting function.

[0023] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0024] like Figure 1 to Figure 2 shown.

[0025] The present invention discloses an edge trimming structure of a prefabricated steel structure floor deck, comprising:

[0026] During assembly, a steel beam 11 is fixed to the vertical steel of the steel structure. The steel beam 11 is composed of an I-beam. A bottom template 12 is installed on the steel beam 11. A corrugated galvanized sheet 13 is laid on the bottom template 12. There are multiple corrugated galvanized sheets 13, and the corrugated galvanized sheets 13 overlap at the joints.

[0027] A vertical limit pin 2 is vertically screwed and fixed on the steel beam 11 located on the side of the corrugated galvanized sheet 13 through a threaded pair, and an L-shaped side template 3 is welded and fixed to the steel beam 11 outside the limit pin 2. The steel beam 11 between the side template 3 and the corrugated galvanized sheet 13 is exposed for fixing the limit pin 2.

[0028] The corrugated galvanized sheet 13 is provided with ribs 4, which provide reinforcement for the concrete 5 poured later.

[0029] The limit pin 2 contacts and presses against the side of the corrugated galvanized sheet 13. The limit pin 2 is sleeved with a stopper 21 that contacts the corrugated galvanized sheet 13. The stopper 21 is fixed to the steel beam 11 by the limit pin 2, and the side of the stopper 21 that contacts the corrugated galvanized sheet 13 is an inclined surface or a straight surface; when the stopper 21 needs to contact and press against the inclined surface of the corrugated galvanized sheet 13, the stopper 21 with an inclined surface is used, and the stopper 21 with a straight surface simultaneously presses against the end of the steel bar of the gluten; when the stopper 21 needs to contact and press against the straight surface of the corrugated galvanized sheet 13, the stopper 21 with a straight surface is used, and the stopper 21 with a straight surface simultaneously presses against the end of the steel bar of the gluten.

[0030] The limit nail 2 vertically fixed on the steel beam 11 contacts the side of the corrugated galvanized sheet 13 to limit the position. When the operator steps on the corrugated galvanized sheet 13, the corrugated galvanized sheet 13 deforms downward and always contacts the stopper 21 on the limit nail 2 to continuously limit the position. At the same time, the limit nail 2 vertically fixed on the steel beam 11 will not be damaged when the downward force is applied, which solves the problem that the welding point 15 between the horizontal connecting rod 14 and the corrugated galvanized sheet is horizontal, and the welding point is easily damaged when the corrugated galvanized sheet elastically deforms and moves downward, causing the horizontal connecting rod to lose its limiting function.
