Description

Technical Field

[0001] This utility model relates to the field of construction safety technology, and in particular, to a device for fixing edge guardrails. Furthermore, it also relates to a protective device including the aforementioned edge guardrail fixing device. Background Technology

[0002] During the construction phase of the main structure of a building project, there is a risk of falling from height at the edge of the staircase. To ensure construction safety, temporary guardrails are usually installed on the staircase.

[0003] Existing temporary guardrails are typically installed by directly fixing them to the treads or landings of stairs using expansion bolts. For example, patent application number 201811064288.3 discloses an adjustable stair guardrail consisting of a movable bracket and a guardrail. The bracket is fixed to the concrete stair platform, and the guardrail is fitted onto the bracket and secured with adjusting screws. While this patent provides some protection by fixing the temporary guardrail to the concrete stair platform with expansion bolts, it occupies the width and surface area of ​​the staircase. After the main building structure is completed, it needs to be removed to allow for plastering, tiling, and other decorative finishing work on the staircase. During this construction period, the lack of safety measures on the staircase increases the risk of accidents. Furthermore, removing the temporary guardrail damages the staircase structure, affecting the quality of the decorative finishing work. Additionally, installing the permanent guardrail after the decorative finishing work is completed will damage the finished decorative finish.

[0004] Existing temporary guardrails are also installed on the side of stair treads. This method allows the temporary guardrails to be installed without removing them during the construction of the decorative surface layer of the staircase. However, this method also uses expansion bolts to drill holes in the side of the stair treads to fix the temporary guardrails. As a result, problems such as the expansion bolts causing wall damage due to perforation and the expansion bolts easily loosening, leading to an unstable installation of the temporary guardrails, will also occur. In addition, removing the temporary guardrails requires cutting operations, which is time-consuming and labor-intensive, affecting construction efficiency. Furthermore, the removed parts cannot be reused, have poor versatility, and result in a large amount of material waste. Utility Model Content

[0031] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0032] like Figure 1 and Figure 2 As shown, the edge guardrail fixing device of this embodiment includes an embedded part 10 for pre-embedding within the protective body and a connecting part 20 for connecting with the embedded part 10 to install the guardrail on the side of the protective body. Specifically, the embedded part 10 is located inside the edge of the protective body and is arranged horizontally. A connecting hole is provided inside the embedded part 10, with the opening facing the side of the protective body and communicating with the outside of the protective body. Thus, the connecting part 20 can be inserted into the connecting hole for connection and fixing, thereby achieving the installation of the guardrail on the side of the protective body. Preferably, at least one connecting hole is provided in the embedded part 10, and the connecting hole is a threaded hole. The edge guardrail fixing device of this embodiment uses the embedded part 10 to fix the guardrail, making the guardrail easy to position and install, safe and secure. Compared with the existing technology of directly drilling holes with expansion bolts for fixing, it does not damage the surface of the staircase, and the removal of the guardrail does not require cutting operations, ensuring the aesthetics of the protective body and saving time and effort. By installing guardrails on the sides of the protective structure, the decorative surface layer on the plane of the protective structure is not damaged, ensuring the quality of the decorative surface layer construction. On the other hand, the guardrails on the sides of the protective structure do not affect subsequent construction, so the guardrails do not need to be disassembled during the decorative surface layer construction, which is convenient and quick, greatly improving construction efficiency. Moreover, the guardrails on the sides of the protective structure can provide continuous protection during the decorative surface layer construction, avoiding the loss of protection of the protective structure due to the removal of the guardrails, ensuring safety throughout the entire construction period, and achieving effective protection of the protective structure throughout the entire construction cycle.

[0033] like Figure 2 As shown, the connector 20 includes a fixing frame 21 and a mounting bracket 22 fixed to the fixing frame 21. The fixing frame 21 is used to extend into the connection hole of the embedded part 10 and detachably connect with the embedded part 10. Preferably, the connection hole between the fixing frame 21 and the embedded part 10 is threaded. By making the connection between the embedded part 10 and the connector 20 detachable, the installation and removal of the guardrail can be facilitated, saving labor. The disassembly operation will not damage the main body of the guardrail, allowing for reuse and avoiding material waste, effectively reducing costs and increasing practicality. The mounting bracket 22 is a movable clamp for inserting and tightening the guardrail. Thus, by making the mounting bracket 22 a clamp structure, flexible adaptation to guardrails of different diameters can be achieved, effectively improving the scope of application, reducing the requirement for the fixed length of the guardrail, and the installation of the mounting bracket 22 and the guardrail by insertion is more convenient and faster than the traditional buckle fixing, facilitating maintenance and replacement.

[0034] like Figure 1 and Figure 2 As shown, the fixing frame 21 includes a fixing plate 211 and connecting rods 213 and connecting plates 212 respectively fixed on both sides of the fixing plate 211. The end of the connecting plate 212 away from the fixing plate 211 is fixed to the mounting frame 22. The connecting rods 213 are adapted to the connecting holes so as to pass through the connecting holes of the embedded part 10 and be threadedly fixed to the connecting holes, so as to press the fixing plate 211 against the side of the protective body. In this embodiment, there is one connecting rod 213, and one connecting rod 213 and the fixing plate 211 are fixed by welding. Preferably, the connecting rod 213 is a screw. Preferably, the connecting plate 212 and the connecting rod 213 are both located at the center of the fixing plate 211 to ensure stable and uniform force and to ensure the structural integrity and reliability. In use, the connection and disassembly between the connecting part 20 and the embedded part 10 can be realized by rotating the connecting rod 213. The installation and disassembly are convenient and quick, saving time and effort, saving labor, and greatly improving work efficiency.

[0035] Optionally, in another embodiment, the connecting rod 213 is a bolt, and the fixing plate 211 has at least two through holes to prevent the fixing plate 211 from rotating circumferentially. The number and position of the connecting holes on the embedded part 10 correspond to the through holes on the fixing plate 211. By sequentially inserting the bolts into the through holes of the fixing plate 211 and the connecting holes of the embedded part 10, the connection and fixation of the connecting part 20 and the embedded part 10 can be achieved.

[0036] like Figure 1 and Figure 2As shown, the mounting bracket 22 includes a fixed ring 221 fixed to the connecting plate 212, a movable ring 222 opposite to the fixed ring 221, a movable connecting member 223 for rotatably connecting the movable ring 222 to the fixed ring 221, and a locking member 224 for engaging the fixed ring 221 and the movable ring 222. The movable connecting member 223 and the locking member 224 are respectively arranged on both sides of the fixed ring 221, and the fixed ring 221 and the movable ring 222 enclose an installation space for accommodating the guardrail. Specifically, both the fixed ring 221 and the movable ring 222 are arranged along the height direction so that the guardrail is vertically inserted into the installation space and extends above the protective body, ensuring effective protection for the protective body. Preferably, both the fixed ring 221 and the movable ring 222 are semi-ring structures so that the shape of the installation space matches the shape of the cylindrical guardrail, increasing the contact area with the guardrail and improving the stability of the installation. Preferably, the fixed ring 221 and the movable ring 222 have a certain height to guide the insertion of the guardrail within the installation space, while ensuring the stability of the bottom of the guardrail installation, preventing the guardrail from tilting, and ensuring the installation quality of the guardrail. The movable connector 223 is located on the side of the fixed ring 221 near the connecting plate 212. The movable ring 222 is mounted on the connecting plate 212 via the movable connector 223 to achieve relative rotation with the fixed ring 221. Therefore, by rotating the movable ring 222 to control its opening and closing, the size of the installation space between the movable ring 222 and the fixed ring 221 can be adjusted, allowing the installation space to flexibly adapt to guardrails of different diameters, thus improving its applicability. The locking member 224 is located on the side of the fixed ring 221 away from the connecting plate 212. After the guardrail is inserted into the installation space, the locking member 224 can tighten the guardrail within the installation space, ensuring it is securely clamped and guaranteeing the firmness and reliability of the guardrail installation.

[0037] like Figure 2 As shown, the ends of the fixed ring 221 and / or the movable ring 222 are fixed with a support plate 225. The support plate 225 is arranged at the bottom of the installation space to support the guardrail, so as to prevent the guardrail from falling out of the installation space due to insufficient clamping force between the fixed ring 221 and the movable ring 222 or deformation of the guardrail, thus ensuring the stable and reliable installation of the guardrail, improving safety, and preventing the occurrence of safety accidents.

[0038] like Figure 2As shown, the movable connector 223 includes a plug block 2231 and a rotating shaft 2023. The plug block 2231 has a shaft hole, and the rotating shaft 2023 is inserted into the shaft hole and rotates within it. One of the fixed ring 221 and the movable ring 222 is connected to the plug block 2231, and the other is connected to the rotating shaft 2023. In this embodiment, the connecting plate 212 has a clearance groove for accommodating the plug block 2231. The rotating shaft 2023 is located in the clearance groove, and the plug block 2231 is movably inserted into the rotating shaft 2023 through the shaft hole, allowing the movable ring 222 to rotate relative to the fixed ring 221. In use, the opening and closing of the movable ring 222 and the fixed ring 221 can be controlled by rotating the movable ring 222, thereby adjusting the size of the installation space to accommodate guardrails of different diameters within the installation space. This provides high flexibility and improves the on-site adaptability of the device. Preferably, two plug-in blocks 2231 and two clearance slots are respectively arranged, with the two plug-in blocks 2231 located at both ends of the movable ring 222. Two rotating shafts 2023 are also respectively arranged with the plug-in blocks 2231 to enhance the stability of the connection of the movable ring 222 and ensure its smooth rotation. Optionally, the plug-in blocks 2231 can also be fixed to at least one location on the fixed ring 221, the connecting plate 212, and the fixed plate 211, and the rotating shafts 2023 can be correspondingly fixed to the movable ring 222. Optionally, the rotating shafts 2023 can also be fixed to the fixed ring 221 or the fixed plate 211.

[0039] like Figure 1 and Figure 2 As shown, the locking component 224 includes a first locking block 2241 fixed to the fixed ring 221, a locking buckle rotatably mounted on the first locking block 2241, and a second locking block 2244 fixed to the movable ring 222. The second locking block 2244 has a groove corresponding to the locking buckle. The locking buckle is rotatably mounted on the first locking block 2241 and is used to engage in the groove to lock the second locking block 2244 to itself. Specifically, two first locking blocks 2241 are arranged parallel to each other along the height direction, and a rotating shaft is fixed between the two first locking blocks 2241. The locking buckle is rotatably mounted on the rotating shaft in the horizontal direction. Optionally, the rotating shaft can also be movably mounted on the two first locking blocks 2241, with the locking buckle fixed to the rotating shaft, allowing the locking buckle to rotate relative to the first locking block 2241. After the guardrail is inserted into the installation space between the fixed ring 221 and the movable ring 222, rotate the locking buckle to engage it in the groove of the second locking block 2244 to lock it in place, thereby tightening the guardrail.

[0040] like Figure 1 and Figure 2As shown, the locking buckle includes a locking rod 2242 and a locking ring 2243 sleeved on the locking rod 2242. The locking rod 2242 is arranged in a horizontal direction and is rotatably connected to the first locking block 2241. The outer diameter of the locking rod 2242 is smaller than the inner diameter of the groove of the second locking block 2244 so as to be easily locked in the groove. The outer wall of the locking rod 2242 is provided with external threads, and the locking ring 2243 is threadedly connected to the locking rod 2242. When it is necessary to lock the fixed ring 221 and the movable ring 222, rotate the locking rod 2242 so that it is engaged in the groove of the second locking block 2244, and place the locking ring 2243 outside the second locking block 2244. Then, rotate the locking ring 2243 so that it moves toward the wall of the second locking block 2244, so as to press the second locking block 2244 onto the first locking block 2241, thereby locking the fixed ring 221 and the movable ring 222, and ensuring that the guardrail in the installation space is securely installed.

[0041] In another embodiment, the mounting bracket 22 adopts an L-shaped sleeve. One end of the L-shaped sleeve is fixed to the connecting plate 212 and / or the fixing plate 211, and the opening of the other end faces upward. The guardrail is inserted into the L-shaped sleeve. The side wall of the L-shaped sleeve has an abutment hole. By screwing a bolt into the abutment hole, it abuts against the outer wall of the guardrail, thereby securing the guardrail tightly inside the L-shaped sleeve. Optionally, through holes can be opened on the side walls of the L-shaped sleeve and the guardrail respectively. Bolts can be passed through the through holes of the L-shaped sleeve and the guardrail in sequence to achieve lateral insertion and fixation of the guardrail.

[0042] like Figure 3 As shown, the embedded part 10 includes an embedded sleeve 11, with a connecting hole axially formed inside the embedded sleeve 11. Limiting structures 12 are provided at both ends of the embedded sleeve 11. Each limiting structure 12 includes a limiting sleeve and reinforcing ribs connecting the limiting sleeve and the embedded sleeve 11. The outer diameter of the limiting sleeve is larger than the diameter of the embedded sleeve 11. The reinforcing ribs are ring-shaped on the outer wall of the embedded sleeve 11. Therefore, the limiting structure 12 significantly enhances the tensile strength of the embedded sleeve 11 within the protective body, preventing the embedded sleeve from detaching from the protective body and ensuring the embedded part 10 is securely installed within the protective body. Preferably, the limiting structure 12 and the embedded sleeve 11 are integrally formed. Optionally, the limiting structure 12 can also be a reinforcing bar connected to the embedded sleeve 11. Preferably, the outer wall of the embedded sleeve 11 and / or the limiting structure 12 is provided with anti-slip textures to further enhance the stability of the embedded sleeve 11 within the protective body.

[0043] Preferably, the edge protection railing fixing device further includes a kick plate installed on the side of the protective body.
