Technical Field
[0001] This utility model relates to the field of building construction, specifically a protective railing that is easy to assemble and disassemble for use in building construction. Background Technology
[0002] Guardrails are commonly made of steel, such as round steel pipes, square steel pipes, or profiled steel sheets. The surface treatment of outdoor crash barriers uses waterproof materials. The resulting crash barriers are aesthetically pleasing and rust-resistant. However, construction guardrails on the market cannot be adjusted in size from the guardrail itself, are complicated to install and disassemble, and are not easy to move.
[0003] To solve the above problems, after searching, Chinese Patent No. CN214463215U was found, which discloses a protective railing for easy assembly and disassembly in building construction. The paper includes a central rod and a slot. The lower end of the central rod is provided with a central rod movable track, and a central extension rod is connected inside the central rod movable track. The two ends of the central rod are connected with a third movable rod, and a second movable rod is provided outside the third movable rod. A first movable rod is installed outside the second movable rod, and a side rod is fixed at one end of the first movable rod. In the aforementioned device, both the central extension rod and the side extension rods are solid steel blocks with conical lower ends, which can be inserted into the construction site to achieve a balanced and more stable guardrail. However, in actual use, the soil at construction sites is hard, and there are many rocks underground. Due to the obstruction of hard soil and underground rocks, the actual insertion depth of the extension rod is often far lower than the design requirements. In this case, the extension rod can only play a "point support" role, rather than an "embedded fixation". When the guardrail is subjected to lateral thrust (such as personnel collision or wind), it is very easy to overturn around the bottom of the extension rod, completely losing its balance and stability function. Utility Model Content
[0004] The purpose of this utility model is to provide a protective railing that is easy to assemble and disassemble for building construction, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, a protective railing for easy assembly and disassembly in building construction is provided, comprising a side frame, a railing stabilizer installed on the inner side of the side frame, support feet installed on both sides of the bottom of the railing stabilizer, a support column fixedly installed on the top of the support feet, a railing docking column fixedly installed on the side wall of the support foot on one side of the bottom of the railing stabilizer, and a railing docking hole opened on the side wall of the support foot on the other side of the bottom of the railing stabilizer.
[0006] Furthermore, two sets of side frames are arranged parallel to each other on both sides of the rail stabilizer, and each set of side frames has a disassembly and assembly space inside.
[0007] Furthermore, the surface of the balustrade stabilizer is provided with multiple sets of protective rods at equal intervals. The end of the protective rod away from the balustrade stabilizer is fixedly provided with a balustrade upper seat. At the same time, the balustrade upper seat and the balustrade stabilizer are arranged in parallel. Both the balustrade upper seat and the balustrade stabilizer are rectangular, and the width of the balustrade upper seat is smaller than the width of the balustrade stabilizer.
[0008] Furthermore, buffer seats are fixedly installed on the outer side of multiple sets of protective rods. The buffer seats have a rectangular cross-section, and both ends of the buffer seats are arc-shaped.
[0009] Furthermore, both ends of the rail seat and the rail stabilizer are fixedly provided with docking seats, which are adapted to the size of the disassembly and assembly space, and the docking seats are inserted into the interior of the disassembly and assembly space.
[0010] Furthermore, the railing seat and the railing stabilizer are positioned and installed between the two sets of side frames through the disassembly and assembly space and the docking seat. The bottom of the docking seat on the side wall of the railing stabilizer is supported by the support column.
[0011] Furthermore, the support column is fixedly connected to the top of the support foot, the support column is adapted to the size of the disassembly and assembly space, and the support column is inserted into the bottom of the disassembly and assembly space.
[0012] Furthermore, the side frame, the railing stabilizer, and the support feet are combined to form a guardrail, and the guardrail adopts a split design. The guardrails are connected to each other by two sets of guardrail connecting posts inserted into the two sets of guardrail connecting holes. The guardrail connecting posts pass through the guardrail connecting holes and are fixed by nuts.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution consists of a side frame, a railing stabilizer, and support legs to form a guardrail. The guardrail adopts a split design, which makes the guardrail more convenient to transport and store. Each component can be disassembled and stored or transported separately, which can effectively save space, reduce the volume occupied during transportation, and reduce transportation costs. At the same time, it avoids the problem of bumping and damage that the overall guardrail is prone to during handling and storage due to its large size. 2. This solution achieves a stable connection between guardrails through the precise matching of two sets of guardrail connecting posts and guardrail connecting holes in multiple guardrail combination scenarios. This connection method can tightly connect individual guardrails into a whole, greatly enhancing the impact resistance and integrity of the overall protective structure, avoiding displacement or tilting of individual guardrails due to uneven force, and further ensuring that the guardrails remain stable during operation, providing reliable safety protection for the protected area. It also eliminates the need to use stakes to fix the guardrails to the construction ground, ensuring the stability of the guardrails during operation and preventing overturning.

[0016] Please see Figure 1-6 This utility model provides a protective railing for easy assembly and disassembly in building construction, including a side frame 1, a railing stabilizer 2 installed on the inner side of the side frame 1, support feet 3 installed on both sides of the bottom of the railing stabilizer 2, a support column 31 fixedly installed on the top of the support foot 3, a railing docking column 32 fixedly installed on the side wall of the support foot 3 on one side of the bottom of the railing stabilizer 2, and a railing docking hole 33 opened on the side wall of the support foot 3 on the other side of the bottom of the railing stabilizer 2.
[0017] As a preferred embodiment, two sets of side frames 1 are arranged parallel to each other on both sides of the railing stabilizer 2, and each set of side frames 1 has a disassembly and assembly space 11 inside.
[0018] Multiple sets of guardrails 22 are equidistantly arranged on the surface of the guardrail stabilizer 2. A guardrail seat 24 is fixedly installed at the end of the guardrail 22 away from the guardrail stabilizer 2. The guardrail seat 24 and the guardrail stabilizer 2 are arranged in parallel. Both the guardrail seat 24 and the guardrail stabilizer 2 are rectangular. The width of the guardrail seat 24 is smaller than the width of the guardrail stabilizer 2.
[0019] Multiple sets of protective rods 22 are fixedly equipped with buffer seats 23 on their outer sides. The cross-section of the buffer seat 23 is rectangular, and both ends of the buffer seat 23 are arc-shaped.
[0020] Both ends of the rail seat 24 and the rail stabilizer 2 are fixedly provided with docking seats 21. The docking seats 21 are adapted to the size of the disassembly and assembly space 11, and the docking seats 21 are inserted into the interior of the disassembly and assembly space 11.
[0021] The upper rail seat 24 and the rail stabilizer 2 are positioned and installed between the two sets of side frames 1 through the disassembly space 11 and the docking seat 21. The bottom of the docking seat 21 on the side wall of the rail stabilizer 2 is supported by the support column 31.
[0022] The support column 31 is fixedly connected to the top of the support foot 3. The support column 31 is adapted to the size of the disassembly and assembly space 11. The support column 31 is inserted into the bottom of the disassembly and assembly space 11.
[0023] like Figure 1-5 As shown: Firstly, the installation is extremely convenient and efficient. During installation, simply place the two sets of support legs 3, then hold the two sets of side frames 1. The side frames 1 and support legs 3 can be easily connected via the disassembly / assembly space 11 on the side frames 1 and the support columns 31 on the support legs 3, quickly forming the main frame. Subsequently, simply hold the railing stabilizer 2 and insert the connecting seats 21 on both sides of the railing stabilizer 2 and the railing top seat 24 into the disassembly / assembly space 11 to complete the assembly and installation of a single guardrail. The entire process requires no complex tools or professional skills; ordinary people can operate it smoothly, significantly reducing the installation threshold and time cost. Secondly, the split design makes... The guardrails are more convenient to transport and store. Each component can be disassembled and stored or transported separately, which can effectively save space, reduce the volume occupied during transportation, and lower transportation costs. It also avoids the problem of bumps and damage that are easily caused by the large size of the guardrail during handling and storage. In addition, this design also has good flexibility and practicality. When a part of the guardrail is damaged, there is no need to replace the entire guardrail. Only the damaged part needs to be replaced, which significantly reduces maintenance costs. Moreover, when it is necessary to adjust the use position or quantity of the guardrails, disassembly and reassembly are very convenient, which can better adapt to the use needs of different scenarios.
[0024] As a preferred implementation, the side frame 1, the railing stabilizer 2, and the support foot 3 are combined to form a guardrail. The guardrail adopts a split design. The guardrails are connected by two sets of guardrail connecting posts 32 inserted into the two sets of guardrail connecting holes 33. The guardrail connecting posts 32 pass through the guardrail connecting holes 33 and are fixed by nuts.
[0025] The stabilizing base 2, as the heaviest component of the guardrail, is located at the bottom of the guardrail, lowering its center of gravity. Simultaneously, numerous guardrail sections are stably connected via two sets of guardrail connecting posts 32 and guardrail connecting holes 33, further ensuring the stability of the guardrail during operation. The strategic placement of the stabilizing base 2 at the bottom of the guardrail directly lowers its overall center of gravity. Based on the physical principle that a lower center of gravity makes an object more stable, this effectively reduces the risk of the guardrail tipping over due to external impacts, wind, or other factors during use, thus improving the overall stability of the guardrail from the structural level of the individual guardrail itself. First, it provides a solid and stable foundation. Second, in scenarios where multiple guardrails are used in combination, the precise cooperation between two sets of guardrail connecting posts 32 and guardrail connecting holes 33 achieves a stable connection between the guardrails. This connection method can tightly connect individual guardrails into a whole, greatly enhancing the impact resistance and integrity of the overall protective structure. It avoids the problem of displacement or tilting of individual guardrails due to uneven force, further ensuring that the guardrails remain stable during operation and providing reliable safety protection for the protected area. It also ensures the stability of the guardrails during operation and prevents them from overturning, without the need to use stakes to fix them to the construction ground.
[0026] Working principle: When installing this guardrail, first place the two sets of support legs 3. Then, hold the two sets of side frames 1 and connect the side frames 1 and support legs 3 through the disassembly space 11 and support column 31 to form the main frame. Then, hold the guardrail stabilizer 2 and insert the docking seats 21 on both sides of the guardrail stabilizer 2 and the upper guardrail seat 24 into the disassembly space 11 to complete the assembly and installation of a single guardrail. The separate assembly method makes it easy to disassemble and assemble the guardrail.
