Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically to an assembled guardrail for construction. Background Technology

[0002] Construction sites are often cluttered with materials and equipment. During construction, guardrails are typically used to demarcate construction areas, ensure the safety of workers, and prevent unauthorized personnel from entering. Common types include steel pipe assembled guardrails, which are usually composed of steel pipe posts and crossbars connected by bolts; there are also mesh assembled guardrails, which are assembled from metal mesh panels and posts using snap-fit ​​methods; and there are also some plastic assembled guardrails, which are assembled using a plug-in method.

[0003] However, there is a common problem of low assembly and disassembly efficiency. The bolted connection requires the use of tools such as wrenches during installation and disassembly, which is cumbersome and consumes a lot of manpower and time. This is especially true when the position of the guardrail needs to be frequently adjusted or temporary protection needs to be provided at the construction site, which seriously affects the construction progress. In addition, there is a problem of poor versatility. The size and specifications of existing assembled guardrails are relatively fixed in narrow construction passages and open construction areas. Guardrails of different widths and heights are required, and existing guardrails often cannot meet these needs. This leads to construction units having to purchase guardrails of various specifications, which increases construction costs. Utility Model Content

[0004] The technical problem this invention aims to solve is that bolted connections are inefficient, cannot be quickly deployed, and have poor dimensional versatility, making them unadjustable to suit construction areas of different widths and heights.

[0005] To solve the above technical problems, the present invention provides the following technical solution: The present invention proposes an assembled guardrail for building construction, including a base and a support column vertically arranged on the base. The support column is provided with a guide groove along the height direction and the guide groove passes through both side walls. An adjustable column is slidably arranged in the guide groove. The invention also includes a railing assembly that is detachably connected to the side wall of the adjustable column.

[0006] The railing assembly includes railing posts and horizontal railings set at the top and bottom of the railing posts. The horizontal railings are provided with sliding grooves and adjustable railings that match the cross-section of the sliding grooves are provided in the sliding grooves. The two sets of horizontal railings and adjustable railings are provided with multiple sets of insertion holes along the length direction. It also includes multiple sets of auxiliary posts that penetrate through the lower end and are inserted into the insertion holes. The top of the auxiliary posts is provided with a limit plate.

[0007] Preferred technical solution 1: Connecting blocks are provided on both sides of the adjusting column and the connecting blocks are provided with sockets. The side wall of the railing column is provided with a support plate and a positioning column is provided at the bottom of the support plate. The bottom of the positioning column is chamfered and slidably set in the socket.

[0008] Preferred technical solution 2: The positioning post is provided with a positioning hole and a stop pin is inserted into the positioning hole.

[0009] Preferred technical solution 3: The adjusting column is provided with multiple sets of adjusting holes at equal intervals along the height direction, and the supporting column is provided with adjusting positioning columns.

[0010] Preferred technical solution four: The railing post has a sliding cavity that extends through to the bottom. A height-adjustable railing slides within the sliding cavity. The height-adjustable railing has multiple sets of positioning pin holes along the height direction. The railing post has positioning pins that match the positioning pin holes. A set of horizontal railings at the bottom is connected to the bottom of the height-adjustable railing. The positioning pin and the socket are clearance-fitted, allowing the railing assembly to rotate 0-90° around the positioning pin axis, i.e., the central axis of the socket, to meet the needs of different protection areas such as corners and irregular sites.

[0011] Preferred technical solution five: Reflective strips are provided on the front and rear side walls of the support column, and an LED warning light is installed on the top of the adjusting column through a snap-fit ​​structure. The bottom of the LED warning light is integrated with an ABS battery box.

[0012] Preferred technical solution six: The bottom of the base is also provided with a connecting plate, and anchor bolts are provided at the four corners of the connecting plate to stably fix the base to the ground.

[0013] The present invention proposes an assembled guardrail for building construction, and the beneficial effects achieved by adopting the above structure are as follows:

[0014] (1) By adjusting the sliding fit between the uprights and the support columns, adjusting the quick positioning between the positioning columns and the adjustment holes, and the plug-in connection between the positioning columns and the connecting block in the railing assembly, the disassembly and fastening steps of the parts during assembly are greatly reduced compared with the traditional bolt connection. At the same time, the extension and retraction adjustment of the railing in the horizontal railing sliding groove and the lifting and lowering adjustment of the height adjustment railing in the railing column sliding cavity can be completed without replacing the main structure of the railing, which reduces the material waste and rework caused by size mismatch during construction, significantly improves the installation, adjustment and subsequent disassembly and turnover efficiency of the railing, and reduces labor and time costs.

[0015] (2) In the horizontal direction, the extension and retraction of the railing can be adjusted to adapt to construction areas of different widths. In the vertical direction, the lifting and lowering of the posts and the sliding of the railing can be adjusted to adapt to protection needs of different heights. The auxiliary posts can be replaced with corresponding lengths according to the actual height, breaking the limitation of fixed dimensions of traditional guardrails. The railing components can rotate 0-90° around the central axis of the connecting block socket, which can flexibly adapt to straight construction areas, corner areas and irregularly shaped construction sites. At the same time, the base can be stably fixed to different ground environments through the connecting plate and anchor bolts, making the guardrail suitable for various scenarios in building construction and effectively expanding its application range.

[0016] (3) The PVC reflective strips installed on the front and rear side walls of the support column can reflect light in low light conditions, making it easy for passing personnel and vehicles to notice the position of the guardrail in time; the LED warning light installed on the top of the adjustable column through the snap-on structure can actively emit warning light at night or in dim environments. The dual warning design effectively avoids the risk of personnel and equipment accidentally entering the construction area; at the same time, the anchor bolts fixing the base and the stop pins reinforcing the connection structure further improve the overall stability of the guardrail, reduce the safety hazards caused by the guardrail falling, comprehensively strengthen the safety protection capabilities during the construction process, and significantly improve the safety of the construction site.

[0025] Example 1

[0026] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: An assembled guardrail for building construction includes a base 1 and a support column 2 vertically arranged on the base 1. A guide groove 3 is provided in the support column 2 along the height direction and the guide groove 3 penetrates both side walls. An adjustable column 4 is slidably arranged in the guide groove 3. The guardrail assembly 5 is also included and is detachably connected to the side wall of the adjustable column 4. Multiple sets of adjustment holes 16 are equidistantly arranged in the adjustable column 4 along the height direction. An adjustment positioning column 17 is provided on the support column 2. The height of the guardrail assembly 5 is adjusted by inserting the adjustment positioning column 17 into the corresponding set of adjustment holes 16. The operation is simple and convenient.

[0027] like Figure 4 As shown, the railing assembly 5 includes railing posts 6 and horizontal railings 7 set at the top and bottom of the railing posts 6. The horizontal railings 7 are provided with sliding grooves 8 and adjustable railings 9 that are matched with the cross-section of the sliding grooves 8 are provided in the sliding grooves 8. Multiple sets of insertion holes are provided along the length direction on the two sets of horizontal railings 7 and the adjustable railings 9. It also includes multiple sets of auxiliary posts 10 that penetrate through the lower end and are inserted into the insertion holes. The top of the auxiliary posts 10 is provided with a limit plate 11. In actual use, the connection is completed by inserting the adjustable railings 9 into the sliding grooves 8 on the other set of horizontal railings 7. The operation is simple and convenient.

[0028] like Figure 2 and Figure 3 As shown, connecting blocks 12 are provided on both sides of the adjusting column 4, and the connecting blocks 12 are provided with sockets. The side wall of the railing column 6 is provided with a support plate 13, and a positioning column 14 is provided at the bottom of the support plate 13. The bottom of the positioning column 14 is chamfered and it is slidably set in the socket, realizing the quick connection between the railing assembly 5 and the adjusting column 4. At the same time, the railing assembly 5 can rotate around the central axis of the socket of the connecting block 12 as the center, flexibly adjusting the protection area. In order to further increase the stability of the connection, the positioning column 14 is provided with a positioning hole, and a stop pin 15 is inserted into the positioning hole. After the positioning column 14 is inserted into the slot, the bottom is limited and fixed by the stop pin 15.

[0029] Example 2

[0030] Based on Example 1, such as Figure 2 and Figure 4 As shown, in order to simultaneously adjust the interception height of the horizontal railing 7 during height adjustment, a sliding cavity is provided inside the railing post 6 and extends through to the bottom. A height-adjustable railing 18 slides inside the sliding cavity. Multiple sets of positioning pin holes 19 are provided on the height-adjustable railing 18 along the height direction. Positioning pins 20 that match the positioning pin holes 19 are provided on the railing post 6. The bottom set of horizontal railings 7 is connected to the bottom of the height-adjustable railing 18. At this time, an auxiliary post 10 of the corresponding length can be replaced. It has strong versatility and is easy to install and adjust. In practical use, the positioning post 14 of the railing post 6 is aligned with the socket of the connecting block 12 and inserted to achieve quick connection between the railing assembly 5 and the adjusting post 4. To prevent the positioning post 14 from coming out, a stop pin 15 is inserted after the positioning hole of the positioning post 14 passes through the connecting block 12 for limiting. In addition, the positioning post 14 and the socket are clearance fit, which allows the railing assembly 5 to rotate 0-90° around the axis of the positioning post 14, that is, the central axis of the socket, to meet the needs of different protection areas such as corners and irregular sites.

[0031] To further enhance the safety and warning functions of the guardrail, reflective strips 21 are installed on the front and rear side walls of the support column 2, and LED warning lights 22 are installed on the top of the adjustable column 4 through a snap-fit ​​structure. The bottom of the LED warning light 22 is integrated with an ABS battery box, which contains two rechargeable lithium batteries. The reflective strips 21 are made of PVC material, with a width of 50mm and a length of 1000mm.

[0032] Detailed usage instructions

[0033] 1. Foundation positioning and support column installation

[0034] First, based on the protection requirements of the construction area, multiple bases 1 are placed stably on the ground to ensure that the bases are placed securely, providing a reliable foundation for the entire guardrail system.

[0035] 2. Adjust the preset height of the column.

[0036] According to the required protection height, pre-adjust the adjusting column 4, loosen the adjusting positioning column 17 on the support column 2, and slide the adjusting column 4 up and down along the guide groove 3. When a set of adjusting holes 16 on the adjusting column 4 is aligned with the adjusting positioning column 17, insert the adjusting positioning column 17 into the adjusting hole 16, thereby fixing the adjusting column 4 at the required height.

[0037] 3. Connection and deployment of railing components

[0038] Take out a set of railing components 5, which mainly includes railing posts 6, upper and lower horizontal railings 7 and adjustable railings 9;

[0039] Align the positioning post 14 at the bottom of the support plate 13 on the side wall of the railing post 6 with the socket on the connecting block 12 on the side of the adjusting post 4, and insert it vertically. To ensure a safe connection and prevent it from coming loose, pass the stop pin 15 through the positioning hole on the aligned positioning post 14 to achieve mechanical limiting and fixing.

[0040] At this time, since the positioning post 14 and the socket are in clearance fit, the railing assembly 5 can rotate from 0° to 90° with the central axis of the socket of the connecting block 12 as the center. Depending on the site conditions such as straight lines, corners or irregular areas, the unfolding angle of the railing assembly can be flexibly rotated and positioned to adapt to different protection boundaries.

[0041] 4. Extension and connection of guardrail length

[0042] When the protective length exceeds the length of a single set of railing components, an extended connection can be made. The adjusting railing 9 of one set of railing components 5 is slid out from the sliding groove 8 of the horizontal railing 7 where it is located, and inserted into the sliding groove 8 of the horizontal railing 7 of another adjacent set of railing components 5. This allows for quick end-to-end connection of two or more sets of railing components, which is simple and convenient to operate.

[0043] 5. Installation of auxiliary columns

[0044] Based on the overall height set in step 2, select an auxiliary post 10 of appropriate length, and pass the lower end of the auxiliary post 10 through the corresponding holes on the upper and lower horizontal railings 7 in sequence, so that its bottom is in place. The limiting plate 11 at the top of the auxiliary post 10 can prevent it from falling out of the hole, thereby forming an additional vertical support between the two sets of horizontal railings, enhancing the integrity and impact resistance of the railing.

[0045] 6. Fine-tuning of interception altitude

[0046] If, after adjusting the overall height, it is necessary to simultaneously adjust the ground clearance of the bottom horizontal railing 7 for better protection, the following steps can be taken:

[0047] Remove the positioning pin 20 from the railing post 6.

[0048] Slide the height-adjustable railing 18, causing the connected bottom horizontal railing 7 to move up and down together. When it moves to the appropriate position, that is, when the positioning pin hole 19 is aligned with the positioning pin 20, reinsert the positioning pin 20 to fix it.

[0049] After this operation, the auxiliary column 10 needs to be replaced with one that matches the new interception height, demonstrating the strong versatility and convenience of the design.

[0050] 7. Activation of safety alert function

[0051] Finally, activate the LED warning light 22 mounted on top of the adjustment column 4, which is powered by a built-in rechargeable lithium battery and provides active illumination warning in low light or at night.

[0052] The reflective strips 21 affixed to the side of the support column 2 can create passive reflection under vehicle lights or illumination, further enhancing the warning effect and ensuring the safety of the construction area.

[0053] By following the steps above, the assembly, adjustment, and configuration of this modular guardrail can be completed quickly. The entire process requires no complicated tools, and the connections are all made using plug-in, pin-connection, and snap-fit ​​methods, significantly improving installation efficiency and allowing for flexible adaptation to various complex construction site environments.
