Description

Technical Field

[0001] This utility model relates to the field of edge finishing technology for steel truss floor decking, specifically an edge finishing structure for steel truss floor decking. Background Technology

[0002] Steel truss floor decking is a new type of composite structure floor decking that combines the advantages of traditional floor decking and steel trusses. It is widely used in construction projects. After installation, steel truss floor decking needs to be edge-trimmed to prevent concrete leakage during concrete pouring.

[0003] In existing technologies, when finishing the edges of steel truss floor decks, L-shaped steel plates are typically used. These plates are attached to the side of the steel truss floor deck and bolted together with bolts to complete the finishing process. However, in actual use, if the finished area is suspended, this installation method cannot provide adequate support for the bottom of the finished plate. This may cause the finished plate to detach during concrete pouring due to the tension of the concrete, resulting in concrete leakage. Therefore, a finishing structure for steel truss floor decks is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a finishing structure for a steel truss floor deck to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a finishing structure for a steel truss floor deck, including a steel truss floor deck body, a primary installation opening is provided on the upper side of the steel truss floor deck body, a fixing component is screwed into the primary installation opening, and a finishing plate is fixedly installed on the steel truss floor deck body by multiple fixing components. The fixing component includes a threaded tube, which is screwed into a primary mounting port. The lower side of the threaded tube has multiple movable ports. A limit rod is fixedly installed in each movable port. An adjusting rod is slidably installed on the surface of the limit rod. A positioning foot is fixedly installed at the bottom end of the adjusting rod. A sliding opening is provided on the surface of the adjusting rod. A drive unit is rotatably installed on the inner wall of the threaded tube.

[0006] Preferably, the drive unit includes a metal block, which is rotatably mounted on the inner wall of the threaded tube. A threaded rod is fixedly mounted on the lower side of the metal block, and a lifting block is screwed onto the surface of the threaded rod. Multiple connecting rods are fixedly mounted on the side of the lifting block, and the other ends of the multiple connecting rods are rotatably connected to one end of an adjusting rod.

[0007] Preferably, a cross groove is formed on the upper side of the metal block.

[0008] Preferably, a knob is fixedly installed at the top end of the threaded tube.

[0009] Preferably, a reinforcing rib is provided on one side of the edge trimming plate.

[0010] Preferably, a limit block is fixedly installed at the bottom end of the threaded rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model aligns the holes drilled in the edge trim plate with the primary installation port. A wrench is used to manually turn the knob, which rotates the threaded tube, threading it into the primary installation port. Then, by rotating the metal block, the metal block drives the threaded rod to rotate, which in turn drives the lifting block to descend. The lifting block drives multiple connecting rods to descend simultaneously, which in turn drive multiple adjusting rods to move. The adjusting rods drive the positioning foot to move, and with the cooperation of the limiting rod and the sliding opening, the foot gradually rises, bringing its bottom end close to the lower side of the edge trim plate. Continuing to rotate the metal block ensures the positioning foot is fully against the edge trim plate, pressing it upwards and bringing it into close contact with the lower side of the steel truss floor deck, thus completing the edge trimming of the steel truss floor deck.

[0012] 2. This utility model improves the strength of the edge trim by providing reinforcing ribs on one side of the edge trim, preventing it from tilting due to concrete tension and enhancing the stability of the edge trim structure. Attached Figure Description

[0015] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0016] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0017] like Figures 1-4 As shown, a finishing structure for a steel truss floor deck includes a steel truss floor deck body 1. A primary installation opening is provided on the upper side of the steel truss floor deck body 1. A fixing component is screwed into the primary installation opening. A finishing plate 2 is fixedly installed on the steel truss floor deck body 1 through multiple fixing components. The fixing component includes a threaded tube 5, which is screwed into the first-stage mounting port. Multiple movable ports are opened on the lower side of the threaded tube 5. Limiting rods 13 are fixedly installed in the movable ports. Adjusting rods 12 are slidably installed on the surface of the limiting rods 13. Positioning feet 6 are fixedly installed at the bottom end of the adjusting rods 12. Sliding openings 14 are opened on the surface of the adjusting rods 12. A drive unit is rotatably installed on the inner wall of the threaded tube 5.

[0018] With the above structure, the steel truss floor deck body 1 is the existing technology, consisting of a floor deck and a steel truss. The floor deck is made of galvanized alloy. The steel truss is made of steel bars and metal rods welded together, which will not be described in detail here. The edge plate 2 is also made of galvanized alloy, which has high strength and corrosion resistance. The steel truss floor deck body 1 has four primary installation ports. The number of primary installation ports can be increased or decreased according to the actual situation. Each primary installation port is equipped with a fixing component. The threaded pipe 5 has four mutually perpendicular movable ports on its lower side. Each movable port is equipped with a limiting rod 13. The adjusting rod 12 is slidably mounted on the surface of the limiting rod 13 through a sliding port 14. The sliding port 14 is U-shaped to facilitate the movement of the adjusting rod 12.

[0019] Furthermore, the drive unit includes a metal block 9, which is rotatably mounted on the inner wall of the threaded tube 5. A threaded rod 7 is fixedly mounted on the lower side of the metal block 9. A lifting block 8 is screwed onto the surface of the threaded rod 7. Multiple connecting rods 11 are fixedly mounted on the side of the lifting block 8. The other end of the multiple connecting rods 11 is rotatably connected to one end of the adjusting rod 12.

[0020] With the above structure, an annular groove is opened inside the threaded tube 5, and a metal ring is fixedly installed on the surface of the metal block 9. The metal ring is rotatably installed in the annular groove, so that the metal block 9 is rotatably installed on the inner wall of the threaded tube 5. Four mutually perpendicular connecting rods 11 are fixedly installed on the side of the lifting block 8, corresponding to the number of adjusting rods 12.

[0021] Furthermore, a cross groove 10 is provided on the upper side of the metal block 9.

[0022] With the above structure, the cross groove 10 facilitates the rotation of the Phillips-shaped knife.

[0023] Furthermore, a knob 3 is fixedly installed at the top of the threaded tube 5.

[0024] Thanks to the above structure, knob 3 is hexagonal, making it easy to turn using a wrench.

[0025] Furthermore, a reinforcing rib 4 is provided on one side of the edge trim 2.

[0026] Through the above structure, the reinforcing rib 4 can increase the strength of the edge trim 2, thereby increasing the strength of the entire edge trim structure.

[0027] Furthermore, a limit block 15 is fixedly installed at the bottom end of the threaded rod 7.

[0028] With the above structure, the limiting block 15 at the bottom of the threaded rod 7 can prevent the lifting block 8 from dislodging from the surface of the threaded rod 7.

[0029] Working principle: When using the device, firstly, align the edge trimming plate 2, which needs to be trimmed, with the arrangement of the first-level installation openings on the steel truss floor slab body 1 and drill holes. After drilling, align the holes drilled on the edge trimming plate 2 with the first-level installation openings. Then, with the threaded tube 5 facing down, manually turn the knob 3 with a wrench. The knob 3 drives the threaded tube 5 to rotate, screwing the threaded tube 5 into the first-level installation opening. As the threaded tube 5 is screwed in and moves downward, it passes through the drilled position and out of the underside of the edge trimming plate 2. At the same time, the threaded tube 5 drives multiple limit rods 13 to move. The multiple limit rods 13 will drive the corresponding adjusting rods 12 to move downward. The adjusting rods 12 will drive the corresponding positioning feet 6 to move downward. When the positioning feet 6 are fully exposed on the underside of the edge trimming plate 2... When the knob 3 stops turning, insert the Phillips head knife into the cross groove 10 and then manually turn the Phillips head knife. The Phillips head knife drives the metal block 9 to rotate through the cross groove 10. The metal block 9 drives the threaded rod 7 to rotate. The threaded rod 7 drives the lifting block 8 to descend. The lifting block 8 drives multiple connecting rods 11 to descend simultaneously. The multiple connecting rods 11 drive multiple adjusting rods 12 to move. The adjusting rods 12 drive the positioning foot 6 to move. With the cooperation of the limiting rod 13 and the sliding mouth 14, the foot 6 gradually lifts up and its bottom end approaches the lower side of the edge plate 2. Continue to rotate the metal block 9 so that the positioning foot 6 is completely attached to the edge plate 2 and squeezes the edge plate 2 to move upward, so that it is attached and tightened to the lower side of the steel truss floor deck 1, thus completing the edge finishing of the steel truss floor deck 1.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
