Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a window guard railing suitable for temporary protection during construction. Background Technology
[0002] The construction of permanent window guard railings is usually arranged after the main structure of the building is completed. That is, after the construction of the main basic components such as walls and floor slabs is completed, the permanent window guard railings are installed. After the construction of the permanent window guard railings is completed, the interior decoration and renovation work is carried out.
[0003] During interior decoration and renovation construction, temporary safety railings are usually installed near windows to protect the safety of construction workers and equipment. However, existing technologies for installing temporary safety railings present several problems:
[0004] Firstly, since temporary guardrails will be removed after the interior decoration and renovation are completed, they are often temporarily fixed in order to facilitate removal. This results in problems such as insecure fixing and easy collapse, which in turn poses a threat to the safety of construction workers and equipment, and poses a significant construction safety risk.
[0005] Secondly, since the temporary guardrails need to be removed after the interior decoration and renovation are completed, the wall where the temporary guardrails were installed needs to be repaired after removal, which increases the construction process and workload.
[0006] Thirdly, during the interior decoration and renovation construction process, since the permanent window railings have already been installed, in order to ensure the safety of the interior decoration and renovation construction, the temporary protective railings will inevitably occupy the construction space.
[0007] Therefore, how to solve the problem of occupying construction space when setting up temporary guardrails and ensure that the temporary guardrails are fixed and reliable has become an important technical problem in interior decoration and renovation construction. Utility Model Content
[0008] One of the objectives of this utility model is, at least, to address the problems that inevitably arise during the construction of temporary protective railings in interior decoration and renovation work after the completion of the main construction project, such as occupying construction space and poor erection stability, which affect construction safety. This utility model provides a window guard railing suitable for temporary construction protection. This window guard railing reduces the open space on the permanent window guard railing by adding a detachable temporary protective frame, thus achieving the purpose of temporary protection. The detachable temporary protective frame, installed on the permanent window guard railing, not only reduces the construction time but also eliminates the need for subsequent repairs, significantly saving costs. Furthermore, the disassembled temporary protective frame remains undamaged and can be reused. In addition, the reliable and secure installation of the detachable temporary protective frame on the permanent window guard railing improves the safety of construction personnel and equipment.
[0009] To achieve the above objectives, the technical solution adopted by this utility model includes the following aspects.
[0010] A window guard railing suitable for temporary construction protection includes a permanent window guard railing. The permanent window guard railing includes a permanent window guard horizontal bar fixed at both ends to the side walls, and a permanent window guard vertical bar connected at one end to the permanent window guard horizontal bar. The other end of the permanent window guard vertical bar is fixed to the floor slab below the permanent window guard horizontal bar. A temporary protective frame is detachably installed on the inner side of the permanent window guard railing. The temporary protective frame includes a transverse telescopic bar arranged between the permanent window guard horizontal bar and the floor slab.
[0011] Since permanent window guardrails typically consist of only one horizontal bar, the gap between the horizontal bar and the floor slab is significant. This makes it unsuitable to use the window guardrail directly as a temporary protective barrier during construction. Furthermore, using it directly as a temporary barrier easily leads to scratches and damage on the side of the permanent window guardrail closest to the interior finish, requiring repairs after construction, which affects aesthetics and increases workload. The technical solution presented in this application, which uses a detachable temporary protective frame on the permanent window guardrail, effectively fills the gap between the vertical bar and the floor slab. The gaps between the permanent and permanent window railings provide temporary protection. These temporary protective frames are placed inside the permanent railings to provide construction protection, preventing tools or workers from directly colliding with the permanent railings and thus protecting them. The temporary protective frames include horizontal telescopic bars installed on the permanent railings. During use, the ends of the horizontal telescopic bars extend to the side walls, providing protection along the entire length of the window area. After construction, the horizontal telescopic bars are retracted and then disassembled and installed on the next construction site, allowing the window railings to be reused.
[0012] Preferably, the horizontal telescopic rod includes a fixed rod and a sliding rod. The fixed rod is fixedly installed on the permanent window guard vertical rod by a fixed bracket, and the sliding rod is slidably installed on the fixed rod. The temporary protective frame also includes a vertical telescopic rod connected to the fixed rod, and the vertical telescopic rod is arranged between two adjacent permanent window guard vertical rods.
[0013] The horizontal telescopic bar includes a fixed bar and a sliding bar. The fixed bar is fixed to the permanent window guard vertical bar by a fixing bracket to ensure the horizontal telescopic bar is firmly fixed. The sliding bar is slidably installed on the fixed bar, so that the sliding bar can slide along the axial direction of the fixed bar. The vertical telescopic bar is arranged between two adjacent permanent window guard vertical bars, thereby filling the gap between the permanent window guard vertical bars and further enhancing the temporary protection effect. Arranging the vertical telescopic bar on the fixed bar of the horizontal telescopic bar will not affect the sliding extension and retraction of the horizontal telescopic bar.
[0014] Preferably, the vertical telescopic rod includes a fixed rod and a sliding rod. The fixed rod of the vertical telescopic rod is connected to the fixed rod of the horizontal telescopic rod, and the sliding rod of the vertical telescopic rod is slidably installed on the fixed rod of the vertical telescopic rod.
[0015] The vertical telescopic bar consists of a fixed bar and a sliding bar. The fixed bar of the vertical telescopic bar is fixedly connected to the fixed bar of the horizontal telescopic bar to ensure the stability of the vertical telescopic bar. The sliding bar of the vertical telescopic bar is slidably installed on the fixed bar of the vertical telescopic bar, allowing the sliding bar to slide up and down, thereby increasing the temporary protective height of the window guardrail. The vertical telescopic bar is arranged between two adjacent permanent window guardrails. During use, the sliding bar of the vertical telescopic bar slides upward and extends. After construction is completed, the vertical telescopic bar is retracted and then disassembled and installed on the next construction site, so that the window guardrail can be reused.
[0016] Preferably, the temporary protective frame further includes a vertical movable rod and a horizontal movable rod. The vertical movable rod is mounted on the sliding rod of the horizontal telescopic rod, and the horizontal movable rod is mounted on the sliding rod of the vertical telescopic rod. The vertical movable rod and the horizontal movable rod are connected at their intersection.
[0017] Because the sliding bar of the horizontal telescopic bar slides to the end of the permanent window guard railing for protection, the gap between the permanent window guard vertical bars at the end of the permanent window guard railing is relatively large. By installing a vertical movable bar on the sliding bar of the horizontal telescopic bar, the large gap at the end of the permanent window guard railing can be protected. Similarly, since the vertical telescopic bar is arranged between two adjacent permanent window guard vertical bars, when the sliding bar of the vertical telescopic bar extends above the permanent window guard horizontal bar, by arranging a horizontal movable bar and connecting the horizontal movable bar and the vertical movable bar at the intersection, the temporary protection range of the window guard railing during construction can be further expanded, ensuring construction safety.
[0018] Preferably, the fixing bracket includes a clamping part for mounting on a permanent window guard rod, and a fixing part for fixing a temporary protective frame.
[0019] Furthermore, the clamping part includes a first clamping plate and a second clamping plate arranged side by side, and a clamping space for clamping the permanent window guard vertical bar is formed between the first clamping plate and the second clamping plate.
[0020] Preferably, the fixing part includes a locking screw connected to the first clamping plate, the second clamping plate has a first through hole for the locking screw to pass through, the transverse telescopic rod has a second through hole for the locking screw to pass through, and the locking screw is fixed by a locking nut after passing through the first through hole and the second through hole in sequence.
[0021] When in use, place the second clamping plate inside the permanent window guard vertical rod, place the first clamping plate connected with the locking screw outside the permanent window guard vertical rod, and pass the locking screw through the second clamping plate and the horizontal telescopic rod in sequence, so that the horizontal telescopic rod is fixed to the permanent window guard vertical rod by the fixing bracket.
[0022] Furthermore, the fixing part also includes a clamping screw, which passes through the rear end of the transverse telescopic rod and is attached to the outer side of the second clamping plate, and the other end is provided with a clamping nut.
[0023] By setting a clamping screw, the fixing ability of the fixing bracket to be clamped on the permanent window guard rod can be further improved, ensuring the stability of the temporary protective frame.
[0024] Preferably, the fixed rod of the horizontal telescopic rod and the vertical telescopic rod has a square cross-sectional shape, including a first side, the opposite side of the first side is a second side, a rectangular groove is provided on the second side, a sliding cavity for sliding of the sliding rod is provided in the fixed rod along the axial direction, and sliding ribs are respectively provided in the sliding cavities on both sides of the rectangular groove.
[0025] Preferably, the sliding rod of the horizontal telescopic rod and the vertical telescopic rod has a square cross-section, including a third side and a fourth side on the opposite side. A rectangular groove is provided on the fourth side, and sliding grooves are respectively provided on the third side and the fourth side on both sides of the rectangular groove. The sliding rod is a hollow structure, and strip grooves are provided on the third side and the fourth side. The strip grooves penetrate the third side and the fourth side in the thickness direction and extend to the end of the sliding rod in the length direction. The strip grooves are connected at one end of the fixed rod and not connected at the opposite end.
[0026] The hollow structure of the sliding rod ensures the structural strength of both the horizontal and vertical telescopic rods while reducing the cost per unit meter of both.
[0027] Preferably, the lateral telescopic rod includes a first lateral telescopic rod and a second lateral telescopic rod welded to its ends, the sliding rods of the first lateral telescopic rod and the second lateral telescopic rod sliding towards the two ends of the lateral telescopic rod respectively, and the ends of the sliding rods are provided with rubber pads.
[0028] By placing rubber pads at the ends of the sliding rods, when the sliding rods of the first and second transverse telescopic rods slide to both ends and contact the side walls, the transverse telescopic rods can avoid scratching the wall surface, thus protecting the wall surface from being clean and aesthetically pleasing. After the window guard railings are removed, there is no need to repair the side wall surface separately.
[0029] Preferably, the transverse telescopic rods are arranged in two rows, and the two rows of transverse telescopic rods are fixedly connected by connecting struts, which are located at the connection point between the first and second transverse telescopic rods in each row.
[0030] Preferably, the transverse telescopic rods are arranged in two rows, each row of which includes a relatively independent first transverse telescopic rod and a second transverse telescopic rod. Both the first and second transverse telescopic rods include a fixed rod and a sliding rod. The two rows of first transverse telescopic rods are connected by connecting struts, and the two rows of second transverse telescopic rods are also connected by connecting struts.
[0031] In summary, by adopting the above technical solution, this utility model has at least the following beneficial effects:
[0032] 1. By detachably arranging temporary protective frames on permanent window guard railings, the gap between the permanent window guard vertical bars and the floor slab can be filled to achieve the purpose of temporary protection. At the same time, arranging the temporary protective frames on the inside of the window guard railings can play a construction protection function, which can prevent construction tools or construction personnel from directly colliding with the permanent window guard railings, thereby protecting the permanent window guard railings, avoiding the need for later wall repairs, and reducing construction procedures and workload;
[0033] 2. The temporary protective frame includes horizontal telescopic bars, which are installed on the permanent window guard railing. They are not only firmly fixed but also easy to disassemble. During use, the ends of the horizontal telescopic bars extend to the side wall, thus protecting the window area along its entire length. After construction is completed, the horizontal telescopic bars are retracted and then disassembled and installed on the next construction site, so that the window guard railing can be reused.
[0034] 3. By installing vertical movable bars on the sliding bars of the horizontal telescopic bars, larger gaps at the ends of permanent window guard railings can be protected. Similarly, since the vertical telescopic bars are arranged between two adjacent permanent window guard vertical bars, when the sliding bars of the vertical telescopic bars extend above the permanent window guard horizontal bars, by arranging horizontal movable bars and connecting the horizontal movable bars with the vertical movable bars at the intersection, the temporary protection range of the window guard railings during construction can be further expanded, ensuring construction safety.
[0035] 4. The temporary protective frame is detachably installed on the permanent window guard rod, which solves the problem of occupying construction space when erecting a temporary protective railing alone. At the same time, rubber pads are set on the first and second clamping plates on the inner side of the clamping space to prevent the temporary protective frame from being fixed to the permanent window guard rod and causing damage. It can not only achieve the effect of temporary protection during construction, but also protect the permanent window guard rod. Attached Figure Description

Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances. Example
[0045] like Figure 1-5As shown, the window guardrail applicable to temporary construction protection in this embodiment includes a permanent window guardrail 1. The permanent window guardrail 1 includes a permanent horizontal window guardrail 101 and a permanent vertical window guardrail 102 integrally welded together. The two ends of the permanent horizontal window guardrail 101 are fixed to the side wall 4 of the main building. One end of the permanent vertical window guardrail 102 is connected to the permanent horizontal window guardrail 101, and the other end is fixed to the floor slab 5 below the permanent horizontal window guardrail 101. There are 6 permanent vertical window guardrails 102, including a first permanent vertical window guardrail 1021 and a second permanent vertical window guardrail 1022 near the middle position, and a first permanent vertical window guardrail 1022. The permanent window guards 1023 and 1025 are located outside the first permanent window guard 1021. The second permanent window guard 1022 also includes a fourth permanent window guard 1024 and a sixth permanent window guard 1026 located outside the second permanent window guard 1022. A temporary protective frame 2 is detachably installed on the inner side of the first and second permanent window guards 1021. The temporary protective frame 2 includes two rows of horizontal telescopic rods 21 arranged side-by-side and two rows of vertical telescopic rods 22 arranged side-by-side. The vertical telescopic rods 22 and the horizontal telescopic rods 21 are arranged vertically and connected by welding. The horizontal telescopic bar 21 is clamped and fixed to the permanent window guard vertical bar 102 by the fixing bracket 3. Specifically, in this embodiment, the horizontal telescopic bar 21 is installed on the first permanent window guard vertical bar 1021 and the second permanent window guard vertical bar 1022 by the fixing bracket 3. The two rows of horizontal telescopic bars 21 arranged side by side are welded together by the connecting support rod 23, so that the two rows of horizontal telescopic bars 21 arranged side by side form an integral structure. Since the gap between the permanent window guard horizontal bar and the floor slab is large, and the gap between two adjacent permanent window guard vertical bars is also large, it is not suitable to use the permanent window guard railing directly as a temporary protective railing for construction purposes. When window railings are used directly as temporary protection, they are prone to scratches and damage to the side of permanent window railings closest to the interior decoration, requiring repairs after construction. This affects aesthetics and increases workload. By setting up temporary protective frames, with horizontal telescopic bars between the permanent window railing horizontal bars and the floor slab, and vertical telescopic bars between adjacent permanent window railing vertical bars, the gap between the permanent window railing horizontal bars and the floor slab can be filled, achieving the purpose of temporary protection. At the same time, placing the temporary protective frames inside the window railings can prevent construction tools or workers from directly colliding with the permanent window railings, thus protecting them. During use, the ends of the horizontal telescopic bars 21 can extend to the side wall 4, and the ends of the vertical telescopic bars 22 can also extend above the permanent window railing horizontal bars 101, thus protecting the window area in terms of overall length and height. After construction, the horizontal telescopic bars 21 and vertical telescopic bars are retracted, and then disassembled and installed on the next construction site, allowing the window railings to be reused.
[0046] like Figure 1 and Figure 2 As shown, each row of transverse telescopic rods 21 includes a first transverse telescopic rod 21A and a second transverse telescopic rod 21B. Both the first transverse telescopic rod 21A and the second transverse telescopic rod 21B include a fixed rod 211 and a sliding rod 212. The sliding rod 212 is slidably installed within the sliding cavity 2111 of the fixed rod 211. The ends of the first transverse telescopic rod 21A and the second transverse telescopic rod 21B are welded together. After welding, the sliding rod 212 of the first transverse telescopic rod 21A slides out from its left end, and the sliding rod 212 of the second transverse telescopic rod 21B... The sliding rod 212 slides out from the right end. The sliding rod 212 of the first transverse telescopic rod 21A and the sliding rod 212 of the second transverse telescopic rod 21B slide towards the side walls on both sides. One end of the sliding rod 212 is provided with a rubber pad 24. The rubber pad 24 can be embedded in the hollow cavity of the sliding rod 212 or it can be covered by an end cap structure at the end of the sliding rod 212. The connecting support rod 23 for welding the two rows of transverse telescopic rods 21 is arranged at the welding connection part of the first transverse telescopic rod 21A and the second transverse telescopic rod 21B of the two rows of transverse telescopic rods 21.
[0047] In this embodiment, the vertical telescopic rods 22 are arranged in two rows. The first row of vertical telescopic rods 22 is arranged between the first permanent window guard vertical rod 1021 and the third permanent window guard vertical rod 1023. The second row of vertical telescopic rods 22 is arranged between the second permanent window guard vertical rod 1022 and the fourth permanent window guard vertical rod 1024. The vertical telescopic rods 22 adopt the same structural form as the horizontal telescopic rods, including fixed rods 211 and sliding rods 212. The fixed rods 211 of the vertical telescopic rods 22 are welded to the fixed rods 211 of the horizontal telescopic rods 21 to maintain the stability of the temporary protective frame. The sliding rods 212 of the vertical telescopic rods 22 are slidably installed on the fixed rods 211 of the vertical telescopic rods 22, so that the sliding rods 212 can slide and extend along the axial direction of the fixed rods 211. Figure 4 and Figure 5As shown, the cross-sectional shape of the fixing rod 211 of the horizontal telescopic rod 21 and the vertical telescopic rod 22 is a square structure with a rectangular groove 2114, including a first side 2112, and a second side 2113 opposite to the first side 2112. A sliding cavity 2111 is provided in the middle. When the temporary protective frame 2 is installed, the first side 2112 fits against the side of the permanent window guard vertical rod 102. The rectangular groove 2114 is opened on the second side 2113, and the sliding cavity 2111 on both sides of the rectangular groove 2114 is divided into... A set (two) of sliding ribs 2115 are symmetrically arranged. The shape of the sliding rod 212 of the horizontal telescopic rod 21 and the vertical telescopic rod 22 corresponds to the shape of the sliding cavity 2111 of the fixed rod 211. It is also a square structure with a rectangular groove 2114, including a third side 2121 and a fourth side 2122 on the opposite side. The rectangular groove 2114 is opened on the fourth side 2122. Sliding grooves 2123 are respectively provided on the third side 2121 and the fourth side 2122 on both sides of the rectangular groove 2114. Correspondingly, sliding edges 2115 and sliding grooves 2123 are provided on the fixed rod 211 and the sliding rod 212, so that when the sliding rod 212 slides within the sliding cavity 2111 of the fixed rod 211, the sliding edges 2115 and sliding grooves 2123 cooperate to ensure that the sliding rod 212 slides tightly within the fixed rod 211, avoiding deviation or vibration. The sliding rod 212 adopts a hollow structure, which can reduce the weight of the horizontal telescopic rod 21 and the vertical telescopic rod 22, realizing the lightweight design of the temporary protective frame 2. The third side 2121 and the fourth side A strip groove 2124 is provided on surface 2122. The strip groove 2124 penetrates the third side surface 2121 and the fourth side surface 2122 in the thickness direction. The strip groove 2124 extends to the end of the sliding rod 212 in the length direction and is connected to one end of the fixed rod 211. The end that slides outwards is not connected. The strip groove 2124 is provided so that the locking screw 321 and the abutting screw 322 on the fixed bracket 3 can pass through the sliding rod 212, ensuring that the sliding rod 212 can slide normally along the axial direction of the fixed rod 211. The fixed rod 211 is provided with multiple locking threaded holes 2117 near the end where the sliding rod 212 slides out. When the sliding rod 212 slides into place, a screw or bolt passes through the locking threaded holes 2117 to fix the sliding rod 212 and the fixed rod 211 to each other.
[0048] In one preferred embodiment, the temporary protective frame 2 further includes a vertical movable rod 25 and a horizontal movable rod 26. The vertical movable rod 25 is mounted on the sliding rod 212 of the horizontal telescopic rod 21, and the horizontal movable rod 26 is mounted on the sliding rod 212 of the vertical telescopic rod 22. The vertical movable rod 25 and the horizontal movable rod 26 are connected at their intersections, specifically by binding or by clamping and fixing with a clamping seat. During use, according to the length and height requirements of the temporary protective frame 2, one or more vertical movable rods 25 and horizontal movable rods 26 are respectively installed on the sliding rods 212 of the horizontal telescopic rod 21 and the vertical telescopic rod 22. The horizontal movable bar 26 and the vertical movable bar 25 can reduce the protective gaps at the left and right ends and the top end of the temporary protective frame, further improving the protective capability of the window guardrail. In use, after the temporary protective frame with the horizontal telescopic bar 21 and the vertical telescopic bar 22 is firmly fixed by the fixing bracket 3, the sliding bar 212 of the horizontal telescopic bar 21 and the vertical telescopic bar 22 is extended and fixed, and then the vertical movable bar 25 and the horizontal movable bar 26 are fixed. After the guardrail is used, the vertical movable bar 25 and the horizontal movable bar 26 are removed first, and then the sliding bar 212 of the horizontal telescopic bar 21 and the vertical telescopic bar 22 is retracted. Then the fixing bracket 3 is removed, and the guardrail can be reused in the next construction site.
[0049] like Figure 3As shown, the fixing bracket 3 includes a clamping part 31 for mounting on the permanent window guard vertical rod 102 and a fixing part 32 for fixing the temporary protective frame. The clamping part 31 includes a first clamping plate 311 and a second clamping plate 312 arranged side by side, forming a clamping space 313 for clamping the permanent window guard vertical rod 102 between the first clamping plate 311 and the second clamping plate 312. A rubber pad 24 is arranged on the first clamping plate 311 and the second clamping plate 312 on one side of the clamping space 313. The rubber pad 24 is fixed by adhesive. The fixing part 32 includes a locking screw 321 connected to the first clamping plate 311 and the second clamping plate 312. The upper part has a first through hole 3121 for the locking screw 321 to pass through. The horizontal telescopic rod 21 has multiple second through holes 2116. The locking screw 321 passes through the first through hole 3121 and one of the second through holes 2116 in sequence and is then fixed by a locking nut. The fixing part 32 also includes a clamping screw 322. The clamping screw 322 passes through another second through hole 2116 on the horizontal telescopic rod 21 and its rear end is attached to the outer side of the second clamping plate 312. The other end is provided with a clamping nut for fastening, thereby improving the fixing ability of the fixing bracket 3 to be clamped on the permanent window guard vertical rod 102 and ensuring the stability of the temporary protective frame 2. To further improve the clamping stability of the locking screw 322, a nut 3221 is integrally provided on the end of the locking screw 322 that abuts against one side of the second clamping plate 312. A rubber pad 24 is attached to the nut 3221. The locking screw 321 and the locking screw 322 can be used separately or simultaneously, so that they are clamped and fastened to the permanent window guard vertical rod 102 by the second clamping plate 312 and the first clamping plate 311. The clamping screw 322 can either be used to clamp the second clamping plate 312 by passing the nut 3221 through the second through hole 2116 (the nut 3221 can pass through the second through hole 2116), or the clamping screw 322 can be pre-installed on the horizontal telescopic rod 21 and finally tightened by the clamping nut (the clamping nut cannot pass through the second through hole 2116). There are multiple second through holes 2116, and different second through holes 2116 can be selected according to the position of the permanent window guard vertical rod 102 for installing the fixing bracket 3.
[0050] This embodiment also provides another type of temporary protective frame 2, such as Figure 6As shown, each row of horizontal telescopic bars 21 includes a relatively independent first horizontal telescopic bar 21A and a second horizontal telescopic bar 21B. Both the first horizontal telescopic bar 21A and the second horizontal telescopic bar 21B include a fixed bar 211 and a sliding bar 212. The two rows of first horizontal telescopic bars 21A are connected by connecting struts 23, and the two rows of second horizontal telescopic bars 21B are also connected by connecting struts 23. This structural form of the window guard railing divides the window guard railing into two parts, reducing the weight of the window guard railing and facilitating operation during installation. On the other hand, since there is an error in the permanent window guard vertical bar 102, the temporary protective frame 2 can be better installed on the permanent window guard vertical bar 102 through the fixed bracket 3, reducing installation errors and improving assembly stability.
[0051] The window guardrails used for temporary construction protection in this scheme are operated as follows: Place the first clamping plate 311 with locking screw 321 on the outside of the permanent window guard vertical bar, and place the second clamping plate 312 on the inside of the permanent window guard vertical bar. After the locking screw 321 passes through the first through hole 3121, the second clamping plate 312 is suspended on the locking screw 321. Place the temporary protective frame 2 with horizontal telescopic rod 21 and vertical telescopic rod 22 inside the second clamping plate 312, and simultaneously allow the locking screw 321 to pass through the corresponding second through hole 2116 on the fixing rod 211. Adjust the first clamping plate 311, the second clamping plate 312, and the temporary protective frame 2. After positioning the temporary protective frame 2 (mainly including adjusting the height of the temporary protective frame so that the lower end of the vertical telescopic rod 22 contacts the floor slab 5), the temporary protective frame is clamped and fixed to the permanent window guard vertical rod 102 by tightening the lock nut. At the same time, in order to ensure the stability of the temporary protective frame 2, the abutment screw 322 is passed through the second through hole 2116 of the horizontal telescopic rod 21 at the position close to the locking screw 321, and the temporary protective frame 2 is further fixed by using the abutment nut (or, when the locking screw passes through the second clamping plate 312 and the horizontal telescopic rod 21 in sequence, the abutment screw 322 is pre-passed through the second through hole 2116 of the horizontal telescopic rod 21 from the inside of the second clamping plate 312). (Simultaneously with the locking screw 321, the temporary protective frame is fixed.) After fixing the temporary protective frame 2, the sliding rod 212 is pulled out, allowing it to slide along the axial direction of the fixed rod 211 to its end. Once the rubber pad at the end of the sliding rod 212 contacts the fixed rod 211, a screw or pin is passed through the locking threaded hole 2117 to fix the sliding rod 212 and the fixed rod 211 relative to each other. At the same time, the sliding rod 212 of the vertical telescopic rod 22 is pulled out, allowing it to slide along the axial direction of the fixed rod 211 of the vertical telescopic rod 22 to a suitable position at the top. Then, a screw or pin is passed through the locking threaded hole 2117 to fix the sliding rod 212. After the sliding rods 212 of the telescopic rod 21 and the vertical telescopic rod 22 are fixed, the vertical movable rod 25 is then fixedly installed on the sliding rod 212 of the horizontal telescopic rod 21. After the vertical fixed rod 25 is installed securely, the horizontal movable rod 26 is then connected and installed on the sliding rod 212 of the vertical telescopic rod 22 and the vertical movable rod 25. After the window guard railing is used up, the horizontal movable rod 26 and the vertical movable rod 25 are removed in sequence. Then, the screws or pins used to fasten the sliding rod 212 of the horizontal telescopic rod 21 and the vertical telescopic rod 22 are loosened, the sliding rod 212 is retracted, and finally the fixing bracket 3 is removed. The window guard railing can then be reused in the next location for temporary construction protection.
