Description

Technical Field

[0001] The utility model relates to the technical field of building construction auxiliary equipment, in particular to a concrete guardrail steel formwork edge protection device. Background Art

[0002] During the construction of cast-in-place box girder concrete guardrails, working at height near edges is quite common, especially in construction environments such as those crossing rivers, streams, lines, and roads. The safety of workers during concrete guardrail construction must be guaranteed. Traditional hanging baskets and operating platforms themselves pose certain safety risks. In addition, the lack of suitable hanging points for safety belts poses a major safety concern for construction workers. Therefore, edge guardrails are used in some concrete guardrail construction.

[0003] However, existing edge guardrail connection methods are not robust enough. For example, patent document CN215369076U discloses a "mobile guardrail for edge protection during dam pouring," which uses an insert-tube structure to connect directly to the guardrail structure, allowing for easy disassembly and installation. However, the edge guardrail connection method in this technical solution is not robust enough. This is because after the columns are directly inserted into the insert-tube steel pipe, the columns are not fixed within the insert-tube steel pipe, making the guardrail prone to shaking. In addition, in severe weather such as strong winds or due to worker misoperation, the columns can easily detach from the insert-tube steel pipe, creating certain safety hazards. Utility Model Content

[0004] In order to solve the technical problems in the prior art that the connection method of the edge guardrail structure is not firm enough, the guardrail is prone to shaking or detaching, and a safety hazard occurs, the utility model provides the following technical solutions.

[0005] The utility model discloses a concrete guardrail steel formwork edge protection device, comprising a plurality of welding blocks welded to the guardrail steel formwork and a mounting tube connected to the welding blocks, the mounting tube being connected to a main beam, the main beam being connected to a plurality of cross beams, the two ends of the cross beam being respectively connected to side beams, the lower end of the main beam being provided with an internal threaded end, the internal threaded end being threadedly connected to a connecting column with an external threaded end at the upper end, the lower periphery of the connecting column being provided with a plurality of insertion protrusions, the inner cavity diameter of the mounting tube being matched with the outer diameter of the connecting column and the inner wall of the mounting tube being provided with a plurality of insertion grooves matching with the insertion protrusions, a lower side of the insertion groove being provided with a limiting groove matching with the insertion protrusion, so as to facilitate stably connecting the connecting column to the mounting tube.

[0006] As a further technical solution, the height of the limiting groove is not less than the height of the insertion protrusion.

[0007] As a further technical solution, the opposite side walls of the mounting tube are provided with a first through hole, the connecting column is provided with a second through hole corresponding to the first through hole, and fasteners are inserted into the first through hole and the second through hole.

[0008] As a further technical solution, the fastener is a pin or a bolt.

[0009] As a further technical solution, the protective height of the guardrail formed by the main beam, the cross beam and the side beam is not less than 1.2m.

[0010] As a further technical solution, the main beam, the cross beam and the side beam are connected by welding.

[0011] The beneficial effects of the present invention are as follows: the present invention welds the mounting tube to the existing guardrail steel mold, connects the mounting tube to the main beam via a connecting column, and the insertion protrusion of the connecting column can be inserted into the insertion groove of the mounting tube. When the insertion protrusion is inserted to the lower part of the insertion groove, the connecting column is rotated so that the insertion protrusion enters the limit groove, thereby preventing the guardrail from shaking or detaching and improving the connection stability of the edge guardrail structure. A fastener can also be connected between the mounting tube and the connecting column to further improve the stability of the connection. The connection method is easy to operate, has a protection height of not less than 1.2m, has good protection performance, can meet the edge protection requirements of construction workers, can be hung with a safety belt, is low in cost, and has strong practicality.

[0018] like Figure 1 and Figure 2 As shown, the utility model provides a device for protecting the edge of a concrete guardrail steel formwork, comprising a plurality of welding blocks 6 welded to the guardrail steel formwork 8 and a mounting tube 1 connected to the welding blocks 6, whereby the mounting tube 1 is firmly connected to the guardrail steel formwork. A main beam 3 is connected above the mounting tube 1, and the main beam 3 is connected to a plurality of cross beams 4, and the two ends of the cross beam 4 are respectively connected to side beams 5, whereby the guardrail formed by the main beam 3, the cross beam 4 and the side beam 5 can be used for edge protection, and the protection height of the guardrail is not less than 1.2m. The main beam 3, the cross beam 4 and the side beam 5 can all be made of existing square steel, square tubes and round steel tubes, and the main beam 3, the cross beam 4 and the side beam 5 are connected by welding.

[0019] like Figure 2 and Figure 3 As shown, in a preferred embodiment, a connecting column 2 is connected between the mounting tube 1 and the main beam 3. The connecting column 2 can be a solid steel column or a hollow round steel tube. The connecting column 2 can ensure a more stable connection between the entire guardrail and the mounting tube 1. Specifically, the lower end of the main beam 3 is fixedly provided with an internally threaded end 301. The internally threaded end 301 is machined from a round steel tube and has a threaded inner cavity. The upper end of the connecting column 2 is provided with an externally threaded end 202, which can be threadedly connected to the internally threaded end 301. By turning the connecting column 2, the connecting column 2 can rotate relative to the main beam 3.

[0020] The outer periphery of the lower portion of the connecting column 2 is provided with a plurality of insertion protrusions 201. The inner diameter of the mounting tube 1 matches the outer diameter of the connecting column 2. The inner wall of the mounting tube 1 is provided with a plurality of insertion grooves 101 that match the insertion protrusions 201. Thus, the connecting column 2 can be directly inserted into the mounting tube 1 along the insertion grooves 101.

The limiting groove 102 matches the insertion protrusion 201, and the height of the limiting groove 102 is not less than the height of the insertion protrusion 201. After the connecting column 2 is inserted into the mounting tube 1 along the insertion groove 101, the connecting column 2 is twisted so that the insertion protrusion 201 enters the limiting groove 102 from the insertion groove 101. This can prevent the connecting column 2 from shaking or detaching, and stably connect the connecting column 2 to the mounting tube 1.

[0021] In a preferred embodiment, two first through-holes 103 are defined on opposing sidewalls of the mounting tube 1, and the connecting column 2 is provided with a second through-hole 203 corresponding to the first through-holes 103. Fasteners 7 are inserted into the first and second through-holes 103, 203. Fasteners 7 may be pins or bolts, without particular limitation. After the insertion protrusion 201 of the connecting column 2 enters the retaining groove 102, the fasteners 7 pass through the first and second through-holes 103, 203, securing the connection between the connecting column 2 and the mounting tube 1.

[0022] When the present invention is in use, first thread the external threaded end 202 at the upper end of the connecting column 2 with the internal threaded end 301 at the lower end of the main beam 3, lift the main beam 3, align the lower end of the connecting column 2 with the mounting tube 1, twist the connecting column 2, align the insertion protrusion 201 with the insertion groove 101, loosen the main beam 3, twist the connecting column 2, insert the insertion protrusion 201 from the insertion groove 101 into the limiting groove 102, insert the fastener 7 into the first through hole 103 and the second through hole 203, and the installation of the entire edge protection device can be completed.
