Description

Technical Field

[0001] This utility model relates to the field of building engineering protection technology, specifically a fall protection device for building engineering. Background Technology

[0002] With the increasing demands for safety at construction sites in modern construction projects, fall protection devices are typically used to prevent workers from falling while performing high-altitude work. These devices protect workers, enhance the overall safety of construction operations, and enable workers to complete high-altitude tasks more efficiently.

[0003] In existing technologies, common fall protection measures during construction work include installing fall arrest railings at the edges of openings in high-rise buildings. However, considering that the railings are mainly connected to the wall by bolts, if the railings are not reinforced, the bolts may loosen, leading to tilting due to their own weight and inability to withstand external forces, thus increasing the risk of workers falling. Therefore, a fall arrest device for construction projects is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fall protection device for construction engineering, so as to solve the problem mentioned in the background art that the existing fall protection devices are unstable due to loose connections.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fall arrestor for construction projects includes a reinforcing bracket with a slot on its inner side. A guardrail body is inserted into the slot. A support plate is fixedly connected to the rear of the reinforcing bracket. A vertical plate is fixedly connected to the middle of the top surface of the support plate. An inclined plate is fixedly connected to the top of the vertical plate. A reinforcing bolt is provided in the gap between the support plate and the reinforcing bracket. A movable buckle plate is slidably connected to the rear of the support plate. A spring is fixedly installed on the inner side of the support plate.

[0007] Preferably, the left and right sides of the guardrail body are provided with adjacent side pillars, and the lower and upper middle positions of the side pillars are fixedly connected with connecting plates. The connecting plates are fixedly connected to the guardrail body, and the bottom of the side pillar is fixedly connected with a base. The bottom of the base and the bottom of the reinforcing bracket are on the same horizontal line.

[0008] Preferably, a warning strip is adhered to the lower front end of the guardrail body, and a protective strip is fixedly connected to the upper front end of the guardrail body, with several protective strips arranged equidistantly along the horizontal direction.

[0009] Preferably, the reinforcing bolt and the support plate are interlocked, the upright plate and the guardrail body are parallel to each other, the inclined plate and the support plate are fixedly connected, one end of the spring is fixedly connected to the horizontal end of the movable buckle plate, the movable buckle plate is L-shaped, and one end of the inclined plate abuts against the rear end of the guardrail body.

[0010] Preferably, a guide roller is provided on the inner rear side of the slot, and the guide roller and the reinforcing support are rotatably connected.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this utility model, the addition of a reinforcing bracket, support plate, slot, guide roller, upright plate, inclined plate, movable buckle plate, reinforcing bolt, and spring facilitates the installation of the fall arrest device for construction projects at the edge of high-altitude building openings. With the auxiliary connection of the side support pillars, a bottom reinforcement support structure composed of a reinforcing bracket, support plate, slot, guide roller, upright plate, inclined plate, movable buckle plate, reinforcing bolt, and spring is added to the bottom of the guardrail body. This reinforces the guardrail body after installation, ensuring a more stable installation and preventing problems such as tilting due to its own weight or inability to withstand external forces caused by loose bolt connections later on. This reduces the risk of workers falling. Attached Figure Description

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A fall arrestor for construction projects includes a reinforcing bracket 2, a slot 4 on the inner side of the reinforcing bracket 2, a guardrail body 1 inserted into the inner side of the slot 4, a support plate 3 fixedly connected to the rear of the reinforcing bracket 2, a vertical plate 6 fixedly connected to the middle of the top surface of the support plate 3, an inclined plate 7 fixedly connected to the top of the vertical plate 6, a reinforcing bolt 9 provided in the gap between the support plate 3 and the reinforcing bracket 2, a movable buckle plate 8 slidably connected to the rear of the support plate 3, and a spring 10 fixedly installed on the inner side of the support plate 3.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, side pillars 11 are provided adjacent to each other on the left and right sides of the guardrail body 1. Connecting plates 12 are fixedly connected to the lower middle and upper middle positions of the side pillars 11. The connecting plates 12 and the guardrail body 1 are fixedly connected together. A base 14 is fixedly connected to the bottom of the side pillars 11. The bottom of the base 14 and the bottom of the reinforcing bracket 2 are on the same horizontal line. The side pillars 11, connecting plates 12 and base 14 are mainly used to assist the guardrail body 1 in fixed installation. A warning strip 13 is glued to the lower front face of the guardrail body 1. A protective strip 15 is fixedly connected to the upper front face of the guardrail body 1. Several protective strips 15 are arranged at equal intervals along the horizontal direction. The warning strip 13 serves to warn workers to approach the device.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the reinforcing bolt 9 and the support plate 3 are interlocked, the upright plate 6 and the guardrail body 1 are parallel to each other, the inclined plate 7 and the support plate 3 are fixedly connected, one end of the spring 10 is fixedly connected to the horizontal end of the movable buckle plate 8, the movable buckle plate 8 is L-shaped, one end of the inclined plate 7 is abutting the rear end of the guardrail body 1, and the inclined plate 7 will abut the rear end of the guardrail body 1 to provide support and limitation after the guardrail body 1 is assembled and interlocked; a guide roller 5 is provided at the rear position of the inner side of the slot 4, and the guide roller 5 is rotatably connected to the reinforcing support 2. When the guardrail body 1 is inserted and installed by aligning with the inside of the slot 4, the guide roller 5 can use its own rolling property to guide and assist the insertion of the guardrail body 1.

[0023] Workflow: Before commencing construction, when it is necessary to install fall arrest railings at the edges of openings in high-rise buildings, such as... Figure 3 As shown, first determine the installation distance between the two reinforcing brackets 2.
