Description

Technical Field

[0001] This utility model relates to the field of stair protection technology, and in particular to a simple stair protection device. Background Technology

[0002] Installing guardrails at locations such as the edges of stairwell foundation pits is a crucial step in protecting the safety of construction workers during building construction. Traditional temporary boundary protection connection methods have many drawbacks, mainly the following problems:

[0003] (1) Inconvenience of on-site processing and connection: The connection of protective rods (such as steel pipes) mainly adopts welding and on-site binding methods, which requires workers to operate professional welding skills and takes a long time. The welding quality is greatly affected by the workers' skills and is prone to false welding and detachment, which reduces the stability of the protective railing.

[0004] (2) Defects of simple connectors: Some simple connectors (such as wire binding parts and ordinary buckles) have low connection strength (such as when people lean on them or when they collide with them). Under the action of external forces, the connection strength is easily loosened and they fall off. The protection function cannot be effectively guaranteed, and the universality is difficult to be compatible.

[0005] (3) Construction efficiency and standardization challenges: For traditional connection methods, in order to meet the needs of efficient construction, it takes a long time to fix a set of edge guardrails and spread them from point to area. The lack of standardized connectors in different construction sections and the disorderly connection methods of guardrails are not only detrimental to safety management, but also make it difficult to carry out demolition and turnover work in the later stage, and also easily cause waste of materials.

[0006] In summary, current edge protection connection technologies have limitations in balancing connection strength, construction efficiency, versatility, and cost control. Therefore, it is necessary to develop a detachable protective device that is structurally sound, easy to install, and highly adaptable. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a simple staircase protection device that allows for the convenient installation and removal of temporary boundary protection devices on stairs, while ensuring the safety of workers during construction, and can be reused.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] This utility model provides a simple staircase protection device, comprising several horizontal bars arranged along the inclined direction of the staircase. A connecting rod, connected to the horizontal bars on both floors of the staircase, is fixedly installed on the corner platform connecting the upper and lower floors. Several connecting parts, cooperating with the horizontal bars on both floors, are provided on both sides of the connecting rod. Connecting portions, cooperating with the connecting parts, are provided on both sides of the connecting rod. One end of each connecting part is detachably connected to the connecting portion, and the other end is detachably connected to the horizontal bar. Several bolt holes are evenly arranged circumferentially along the edge of each connecting part. Fastening grooves, cooperating with the bolt holes, are provided on the horizontal bars and connecting portions near the connecting parts. The horizontal bars and connecting portions are bolted to the connecting parts.

[0010] Preferably, the connector has positioning parts fixed at both ends, and the crossbar and the connector have positioning grooves that cooperate with the positioning parts at the end near the connector to assist in adjusting the angle.

[0011] The crossbar includes a main crossbar and a secondary crossbar, and also includes a vertical bar that cooperates with the main crossbar and the secondary crossbar. The protective grid formed by the crossbar and the vertical bar is provided with a protective net. The secondary crossbar also has a hole that cooperates with the vertical bar. The main crossbar has a slot that cooperates with the vertical bar. During assembly, one end of the vertical bar is fixedly connected to the staircase, and the other end passes through the holes of several secondary crossbars and is inserted into the slot.

[0012] The main crossbar is also provided with a fixing hole that mates with the insertion slot. After the vertical bar is inserted into the insertion slot, a bolt is screwed into the fixing hole to fix the vertical bar.

[0013] The connecting rod and the vertical rod are fitted with a fastening pad at the end that is fastened to the staircase.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) In terms of connection strength, the crossbar and connecting rod are connected by connectors, which has strong impact resistance and strong vibration resistance, effectively ensuring the safety of edge protection;

[0016] (2) Flexibility of application scope: This protective device can support multiple angles of connection through the multi-directional adjustment and cooperation structure of the connector, crossbar and connecting rod, which can meet the needs of various edge protection scenarios such as stairwell foundation pit floors;

[0017] (3) Improve construction efficiency. No welding or complicated processing is required. Workers can complete the connection with simple rotation operation. Compared with the traditional method, the construction speed is increased by more than 60%, which greatly shortens the construction time.

[0018] (4) The materials used have a high reusability rate, the connector structure is stable and durable, and can be recycled more than 30 times, which effectively reduces material consumption and construction costs. The highly standardized connection structure and installation process provide convenience for on-site management and quality control, promote the development of standardized edge protection construction, and help strengthen the construction safety system of building construction.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] To address the current challenges in balancing connection strength, construction efficiency, versatility, and cost control in stair edge protection devices, this invention provides a simplified stair protection device. Specifically, it includes several horizontal bars 1 arranged along the inclined direction of the staircase 5. A connecting rod 2, connected to the horizontal bars 1 on the upper and lower staircase 5, is fixed on the corner platform 51 connecting the upper and lower staircase 5. Several connecting pieces 3, which mate with the horizontal bars 1 on the upper and lower staircase 5, are also provided on both sides of the connecting rod 2. The connecting part 21 is detachably connected to one end of the connecting part 21, and the other end is detachably connected to the crossbar 1. Specifically, the connecting part 3 has several bolt holes 32 evenly distributed circumferentially along its edge. The crossbar 1 and the connecting part 21 have fastening grooves 212 near the connecting part 3 that mate with the bolt holes 32. The crossbar 1 and the connecting part 21 are bolted to the connecting part 3. This modularizes the crossbar 1, connecting rod 2, and connecting part 3, allowing for rapid assembly during actual installation. It should be noted that the inclination angle of the staircase 5 varies depending on the construction environment. There will be differences. When using connector 3 to connect crossbar 1 and connecting rod 2, the angle needs to be adjusted first to adapt to the different inclination angles of staircase 5. Therefore, positioning parts 31 are fixed at both ends of connector 3. Preferably, the positioning parts 31 are cylindrical. The crossbar 1 and the connecting part 21 are provided with positioning grooves 211 that cooperate with the positioning parts 31 at the end near connector 3. Thus, in actual installation, the connecting rod 2 is first installed on the corner platform 51, and then connector 3 is installed on the connecting part 21 of the connecting rod 2. When installing connector 3, the positioning part 31 on connector 3 is first inserted into the connecting part 21. The positioning groove 211 of part 21 is used to connect the connecting part 21. Then, the connecting part 3 is rotated to match the tilt angle of the stair 5. The connecting part 3 and the connecting part 21 are then fixed. Finally, the other end of the connecting part 3 is fixedly connected to the crossbar 1 to complete the assembly of the temporary support. In this way, through the modular design, the crossbar 1 and the connecting rod 2 can be connected quickly and easily using the connecting part 3. Compared with wire binding parts and ordinary buckles, it has better connection strength. At the same time, since the crossbar 1, the connecting rod 2 and the connecting part 3 can all be reused after disassembly, the cost of use is greatly reduced.

[0031] To ensure the stability of the horizontal bar 1, it also includes a vertical bar 4. The horizontal bar 1 includes a main horizontal bar 11 and a secondary horizontal bar 12 that cooperate with the vertical bar 4. The secondary horizontal bar 12 is also provided with a hole 121 that cooperates with the vertical bar 4. The main horizontal bar 11 is provided with a groove 111 that cooperates with the vertical bar 4. During assembly, one end of the vertical bar 4 is fixedly connected to the stair 5, and the other end passes through the hole 121 of several secondary horizontal bars 12 and is inserted into the groove 111. In this way, the horizontal bar 1 and the vertical bar 4 together form a protective grid to achieve a better support and protection effect. The protective grid formed by the horizontal bar 1 and the vertical bar 4 is equipped with a protective net. In order to ensure the firmness of the protective grid, the main horizontal bar 11 is also provided with a fixing hole 112 that cooperates with the groove 111. After the vertical bar 4 is inserted into the groove 111, bolts are screwed into the fixing hole 112 to fix the vertical bar 4. At the same time, the intersection of the horizontal bar 1 and the vertical bar 4 can also be tightened and fixed with bolts.

[0032] Preferably, a fastening pad 13 is provided at the end where the connecting rod 2 and the vertical rod 4 are fastened to the stair 5, so as to reduce the damage to the stair 5 when the connecting rod 2 and the vertical rod 4 are fastened to the stair 5.

[0033] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
