Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a safety protection device for working near building edges. Background Technology

[0002] Construction edge work refers to work performed near or across the edges of a building during construction. These edges can be floor edges, roof edges, edges of suspended platforms, excavation edges, etc. Therefore, protective devices must be installed during edge work to improve construction safety and prevent unauthorized personnel from entering.

[0003] However, most existing safety protection devices for construction edge operations are assembled as a single unit, which makes assembly and disassembly inconvenient. Once the protective device is formed, its length cannot be finely adjusted, so it needs to be prefabricated according to the protection range, which is quite troublesome. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection device for construction edge operations, and this utility model effectively solves the technical problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] The safety protection device for construction edge work includes two counterweight bases. The top of the counterweight bases is equipped with a mounting column, and each of the four sides of the mounting column has a slot. The top of the mounting column is fitted with a top cover. Several guardrails are fitted between two adjacent slots in the horizontal direction, and an adjustment structure is connected between the middle of the guardrails. The bottom center and front and rear positions of the top cover are equipped with pin rods. The top surface of the mounting column has a pin groove that matches the pin rod.

[0007] As a further embodiment of this utility model, the enclosure bar includes two card plates that are adapted to the card slot, and the opposite sides of the two card plates are connected to a connecting plate. The opposite ends of the two connecting plates are connected to a connecting rod through a rotating shaft, and the close ends of the two connecting rods are connected through a rotating shaft.

[0008] As a further embodiment of this utility model, the slot is arranged in a cross shape, the top of the slot penetrates the top surface of the mounting column, and the card plate is engaged with the slot.

[0009] As a further embodiment of this utility model, the adjustment structure includes a U-shaped plate. The front and rear inner walls of the U-shaped plate are provided with shaft holes that are adapted to the ends of the rotating shafts connected to the adjacent ends of the two connecting rods. A threaded sleeve is connected to the bottom of the U-shaped plate. A threaded rod is threadedly connected inside the threaded sleeve, and a support plate is connected to the bottom end of the threaded rod.

[0010] As a further embodiment of this utility model, the length of the threaded rod is less than the length of the threaded sleeve, and the inside of the threaded sleeve is provided with a threaded groove that is threadedly connected to the threaded rod.

[0011] As a further embodiment of this utility model, the support plate is circular, and the bottom of the threaded rod is welded and fixed to the center of the top surface of the support plate.

[0012] The beneficial effects of this utility model are:

[0013] This utility model uses an installation column to work with a barrier bar. The installation column has slots on all four sides. During assembly, the barrier bar is engaged with the slots by a locking plate, and the top cover is engaged with the pin slot by a pin rod. This makes the entire protective device easy to assemble and disassemble.

[0014] With the adjustment structure, when the length of the entire protective device needs to be adjusted, the U-shaped plate can be pulled down. The adjacent connecting rods and the connection with the connecting plate are all movable through the pivot, so that they can be bent downwards. At this time, the distance between two adjacent installation columns can be adjusted to match the horizontal length of the entire fence rod after bending. Then, after the entire protective device is assembled, the distance can be finely adjusted according to the construction environment.

[0015] At the same time, a threaded sleeve is set up to cooperate with the threaded rod and the support plate. After the connecting rod is bent, the threaded rod can be driven to the threaded sleeve by rotating the support plate, so that the support plate can be at the same height as the counterweight base. On the one hand, the connecting rod can maintain a stable bent shape, and on the other hand, it can be used to support the counterweight base, making the entire protective device more stable.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1-4 As shown, the safety protection device for working near the edge of a building includes two counterweight bases 1. A mounting column 2 is installed on the top of the counterweight base 1, and a slot 3 is opened in the center of each of the four sides of the mounting column 2. A top cover 4 is attached to the top of the mounting column 2. Several guardrails 5 are attached between two adjacent slots 3 in the horizontal direction, and an adjustment structure 6 is connected between the middle of the guardrails 5. A pin 7 is installed at the bottom center and front and rear positions of the top cover 4. A pin groove that matches the pin 7 is opened on the top surface of the mounting column 2.

[0024] The enclosure bar 5 includes two card plates 8 that are adapted to the card slot 3, and the opposite sides of the two card plates 8 are connected to the connecting plates 9. The opposite ends of the two connecting plates 9 are connected to the connecting rods 10 through the pivot, and the close ends of the two connecting rods 10 are connected through the pivot.

[0025] The two connecting rods 10 are connected by a pivot and can be bent to form a V shape, thus allowing for spacing adjustment.

[0026] The slot 3 is arranged in a cross shape, and the top of the slot 3 penetrates the top surface of the mounting post 2. The card plate 8 is engaged with the slot 3.

[0027] After the card plate 8 is inserted into the card slot 3, the lower card plate 8 can support the upper card plate 8, thereby stabilizing the distance between the upper and lower connecting rods 10.

[0028] The adjustment structure 6 includes a U-shaped plate 12. The front and rear inner walls of the U-shaped plate 12 are provided with shaft holes that are adapted to the ends of the rotating shafts connected to the adjacent ends of the two connecting rods 10. A threaded sleeve 13 is connected to the bottom of the U-shaped plate 12. A threaded rod 14 is threadedly connected inside the threaded sleeve 13, and a support plate 15 is connected to the bottom end of the threaded rod 14.

[0029] By controlling the length of the threaded rod 14 screwed into the threaded sleeve 13, the U-shaped plate 12 can be driven to pull down the connecting rod 10 to bend, thereby adapting to the position adjustment between adjacent mounting columns 2.

[0030] The length of the threaded rod 14 is less than the length of the threaded sleeve 13, and the inside of the threaded sleeve 13 is provided with a threaded groove that is threadedly connected to the threaded rod 14.

[0031] The support plate 15 is circular, and the bottom of the threaded rod 14 is welded and fixed to the center of the top surface of the support plate 15.

[0032] When using the safety protection device for construction edge operations, the number of counterweight bases 1 and mounting columns 2 is set according to the construction environment. Multiple guardrails 5 can be connected between two adjacent mounting columns 2 to form a single-sided protection structure. Four mounting columns 2 are set in parallel in pairs and then connected with multiple guardrails 5 in sequence to form an enclosed protection structure.

[0033] When the enclosure bar 5 is connected to the mounting post 2, the clamping plate 8 is inserted into the corresponding clamping groove 3. The upper connecting rod 10 is supported by the clamping plate 8 connected to it by the clamping plate 8 located at the bottom, so that there is a gap between adjacent connecting rods 10. After the clamping plate 8 and the clamping groove 3 are assembled, the top of the clamping groove 3 can be closed by clamping the top cover 4 with the top of the mounting post 2. The top cover 4 and the mounting post 2 can be assembled by inserting the pin 7 into the pin groove. The counterweight base 1 is set at the bottom of the mounting post 2, which can improve the stability of the mounting post 2.

[0034] When it is necessary to adjust the spacing between adjacent installation columns 2 according to the site environment, simply open the U-shaped plate 12, causing the connection of the adjacent connecting rods 10 to bend downwards into a V-shape through the rotation of the shaft. By rotating the support plate 15, the threaded rod 14 is pulled into the threaded sleeve 13, so that the support plate 15 can be at the same height as the counterweight base 1. The support plate 15 can then support each connecting rod 10. At this time, because the adjacent connecting rods 10 are bent, the spacing between the two installation columns 2 can be reduced to adapt to the construction range and achieve safety protection for construction edge operations. The support plate 15 supports each connecting rod 10, which on the one hand keeps the connecting rods 10 in a stable bent shape, and on the other hand, it can cooperate with the counterweight base 1 for support, making the entire protective device more stable.
