Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a detachable permanent-temporary combined building edge protection railing structure. Background Technology

[0002] Before the installation of the exterior windows, the openings in the exterior walls form edge openings that must be protected against the edge. The current practice is to erect steel pipe guardrails and install standardized protective netting on the inside of the opening, or to fix the window guardrails to the structure inside the opening.

[0003] The aforementioned protective facilities are all located inside the opening, with their members spanning across the opening and directly in the passageway where window frames and glass are transported from inside the room to the opening. They also obstruct the work surface required for workers to complete window frame alignment, fastener installation, caulking, and sealant application inside the opening, making it impossible to proceed with the exterior window installation process normally. To make room for work, the current practice is to remove the protective measures before window installation and then reinstall them afterward. However, repeated disassembly and reassembly increases material waste and labor costs associated with the protective measures, and also affects the efficiency of exterior window installation to some extent.

[0004] Therefore, how to solve the problem of repeated disassembly and reassembly of edge protection during the installation of exterior windows, which increases construction costs and affects construction efficiency, is an urgent problem that needs to be solved by those skilled in the art. Summary of the Invention

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The present invention discloses a detachable permanent-temporary combined building edge protection railing structure. By setting the hinged base at the bottom of the window opening and the limiting bracket on the side of the window opening, and hingedly engaging the end of the main upright of the railing body with the hinged base, the railing body can switch between a protective state and a clearance state around the rotation axis of the hinged base. During normal construction, the railing body is in the protective state, its protective plane is parallel to the window opening, and the horizontal protective rod is fixed by the limiting bracket, forming reliable edge protection. When it is necessary to install the exterior window, simply release the limiting bracket and rotate the railing body around the hinged base towards the interior to a clearance state where it is flush with the interior floor of the building, thus completely clearing the material handling passage and working surface inside the window opening. Therefore, exterior window installation can be completed without removing the protective facilities, avoiding material waste and labor input caused by repeated disassembly and reassembly in the prior art, reducing construction costs, and saving the waiting time for disassembly and reassembly, thereby improving the construction efficiency of exterior window installation. 2. The detachable permanent-temporary combined building edge protection railing structure of the present invention controls the vertical elevation of the window frame through the bearing plate and controls the horizontal axis of the window frame through the sliding of the auxiliary railing, forming a positioning system that is adjustable in both vertical and horizontal directions. This allows the window frame to obtain a stable and accurate temporary positioning before the caulking and fixing plates are installed. Workers no longer need to manually support the window frame and perform alignment at the same time; they only need to make minor checks on the established benchmark. This significantly reduces the difficulty of installing exterior windows and improves installation accuracy and construction efficiency. 3. The present invention provides a detachable permanent and temporary combined building edge protection railing structure, wherein the baffle includes a main plate and two limiting plates. The main plate is connected to the second slider, the limiting plates are disposed at the lower part of the main plate, and the limiting slot is disposed at the junction of the main plate and the limiting plate. The limiting plate and the main plate are rotatably connected. The rotation axis of the limiting plate is parallel to the side of the main plate, and the rotation angle of the limiting plate is greater than or equal to 90°, so that the limiting slot can release the constraint on the bearing plate. With this structural design, the removal of the support plate does not require tightening the locking nut and adjusting bolt in a confined space. It can be completed in one go simply by rotating the limiting plate and flipping the guardrail body. The operation space is ample and the action is simple. At the same time, the downward droop of the folding plate and the flipping of the guardrail body cause the support plate to be removed by disengagement rather than sliding, avoiding friction between the support plate and the bottom of the window frame and effectively protecting the surface and coating of the window frame profile from damage.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] Example 1: As Figures 1 to 3 As shown, the present invention provides a detachable permanent and temporary combined building edge protection railing structure, including a railing body 1, a hinged base 2, and a limiting bracket 3. The guardrail body 1 includes at least two horizontal guardrails 4 arranged in parallel at intervals, and a number of main uprights 5 and secondary uprights 6 vertically connected between the horizontal guardrails 4. The length of the secondary uprights 6 matches the interval width of the horizontal guardrails 4, the length of the main uprights 5 is greater than the interval width of the horizontal guardrails 4, and the end of the main uprights 5 extends beyond the bottom of the guardrail body 1. The hinge base 2 is located at the bottom of the window opening, the limiting bracket 3 is located on the side of the window opening, the end of the main upright 5 is connected to the hinge base 2, and the main upright 5 can rotate around the rotation axis of the hinge base 2 so that the guardrail body 1 can be in a protective state and an avoidance state. In the protective state, the protective plane of the guardrail body 1 is parallel to the window opening; in the avoidance state, the guardrail body 1 is away from the window opening and close to the indoor floor of the building. The limiting bracket 3 is used to lock and fix the horizontal guardrail 4 in the protective state, so that the guardrail body 1 maintains a protective posture facing the window opening.

[0023] The present invention employs a detachable permanent-temporary combined building edge protection railing structure. By setting the hinged base 2 at the bottom of the window opening and the limiting bracket 3 on the side of the window opening, and hingedly engaging the end of the main upright 5 of the railing body 1 with the hinged base 2, the railing body 1 can switch between a protective state and a clearance state around the rotation axis of the hinged base 2. During normal construction, the railing body 1 is in the protective state, its protective plane is parallel to the window opening, and the horizontal protective rod 4 is secured by the limiting bracket 3, forming reliable edge protection. When it is necessary to install an exterior window, simply release the locking constraint of the limiting bracket 3, and rotate the railing body 1 around the hinged base 2 towards the interior to a clearance state where it is flush with the interior floor of the building, thus completely clearing the material handling passage and work surface inside the window opening. Therefore, the installation of exterior windows can be completed without removing the protective facilities, avoiding the material waste and labor input caused by repeated disassembly and reassembly in the existing technology, reducing construction costs, and saving the waiting time for disassembly and reassembly, thus improving the construction efficiency of exterior window installation.

[0024] Specifically, in this embodiment, the two horizontal guardrails 4 are arranged parallel to each other in the vertical direction, and the spacing is determined according to the protection height requirements of the window opening. The horizontal guardrails 4, the main uprights 5, and the secondary uprights 6 can all be made of galvanized steel pipes, square tubes, or structural steel. The members can be connected by welding, bolts, or fasteners to form an overall frame, so that the guardrail body 1 has sufficient overall rigidity and strength to withstand the horizontal thrust and impact loads specified in the "Technical Specification for Safety of High-Altitude Operations in Building Construction".

[0025] The secondary uprights 6 are evenly spaced along the length of the horizontal guardrail 4 to reduce the grid size of the guardrail body 1 and prevent personnel or materials from passing through the gaps between the uprights. In addition to connecting to the upper and lower horizontal guardrails 4, the lower end of the main upright 5 extends downwards beyond the plane of the bottom horizontal guardrail 4. This extended end is used to connect with the hinged base 2. The number of main uprights 5 is determined by the width of the window opening; generally, one is installed on each side of the window opening. For wider window openings, additional main uprights 5 can be added in the middle.

[0026] The hinged base 2 is fixedly installed on the windowsill structure at the bottom of the window opening or on the floor inside the window opening; the limiting bracket 3 is fixedly installed on the side wall of the opening structure on the side of the window opening or on the wall inside the window opening; the two can be fixed by expansion bolt anchoring, chemical anchoring, or welding connection with embedded parts. The limiting bracket 3 can be a clamp structure with an open slot, the slot opening facing the interior, and the size of the slot matching the size of the horizontal guard rod 4; the limiting bracket 3 is also provided with an openable and closable latch or pin, used to close and lock after the horizontal guard rod 4 is inserted into the slot, preventing the horizontal guard rod 4 from coming out of the slot.

[0027] The usage process of this embodiment is as follows: The first step is installation. After the main structure is completed and the window opening is formed, the hinge base 2 is installed at the bottom of the window opening, and the limiting bracket 3 is installed on the side of the window opening. The lower end of the main upright 5 of the guardrail body 1 is inserted into the hinge base 2, and a rotating shaft is inserted to complete the hinge connection.

[0028] The second step is to enter the protective state. The guardrail body 1 is rotated upright around its rotation axis towards the window opening until the protective plane of the guardrail body 1 is parallel to the window opening. At this point, the horizontal guardrail 4 is precisely aligned with the slot opening of the limiting bracket 3. The horizontal guardrail 4 is pushed into the slot and the latch is closed. The guardrail body 1 is then constrained by the limiting bracket 3 and the hinge base 2, forming a hinged support at the lower end and a locking fixation on the side. The guardrail body 1 maintains a protective posture facing the window opening, effectively resisting horizontal thrust and impact loads acting from the interior, thus achieving the edge protection function of the window opening.

[0029] The third step is to switch to the avoidance mode. When it is necessary to install the exterior window, the operator opens the latch of the limiting bracket 3, removes the horizontal guardrail 4 from the slot, and releases the lateral restraint; then, holding the top of the guardrail body 1, slowly rotates it around the rotation axis of the hinge base 2 towards the interior of the building until the guardrail body 1 is in contact with the interior floor. At this time, the space above the inner side of the window opening is completely cleared, and materials such as the window frame 29 and glass can be smoothly transported from the interior to the opening. The operator also has a complete working surface to easily complete the positioning and alignment of the window frame 29, the installation of the fixing pieces, the sealing and caulking, and other processes. Since the guardrail body 1 is laid flat on the ground and does not form a cantilevered obstacle, the operator is less likely to trip when moving inside the opening.

[0030] The fourth step is resetting. After the exterior window is installed, the guardrail body 1 is flipped upside down and erected. The horizontal guardrail 4 is then snapped into the limiting bracket 3 and locked, thus restoring the protective state and continuing to provide edge protection for subsequent processes. The guardrail body 1 can also serve as a permanent railing structure, remaining inside the building as an edge protection facility during the finished product protection stage and after delivery. This truly achieves a combination of temporary and permanent protection, avoiding the repetitive work of removing temporary protection and reinstalling permanent protection later, further saving material and labor costs.

[0031] Example 2: Figures 4 to 7 As shown, the present invention discloses a detachable permanent and temporary combined building edge protection railing structure. Based on the above method, further, an auxiliary railing 7 is provided on the horizontal guardrail 4 at the top of the guardrail body 1. The auxiliary railing 7 and the horizontal guardrail 4 are detachably connected and cooperate, and the auxiliary railing 7 is used to increase the protection height of the guardrail body 1.

[0032] In actual engineering projects, GJ80-2016 requires that the top rail of the edge protection railing be 1.2m above the ground, while the net height of permanent railings, according to GB55031-2022, is only 1.10m when the building height is 24m or above, and only 1.05m when it is below 24m. The protection height requirements during the construction phase are usually higher than the permanent protection height after delivery. In this embodiment, the detachable auxiliary railing 7 can meet the higher protection requirements during the construction phase. Before delivery, the auxiliary railing 7 can be removed to directly meet the requirements of permanent protection specifications without replacing the entire railing, further adapting to the use needs of combining permanent and temporary railings.

[0033] As a preferred embodiment, based on the above method, a kick plate 8 is further provided at the lower part of the guardrail body 1, the kick plate 8 being used to prevent construction debris from falling from the edge of the window opening.

[0034] Tools, bolts, mortar blocks, and scraps of building materials are often scattered on the work surface at construction sites. Without a bottom barrier, these debris can easily be kicked or bumped and slide off the edge of window openings, creating a potential hazard of falling objects from height. In this embodiment, the kick plate 8 is installed at the lower part of the guardrail body 1, with its bottom edge close to the windowsill or floor, effectively blocking the aforementioned debris and improving the safety level of edge protection.

[0035] As a preferred embodiment, based on the above method, a first sliding groove 9 is further provided on the horizontal guardrail 4 at the top of the guardrail body 1; The auxiliary railing 7 includes two first sliders 10, a connecting rod 11, and a clamping member 12. The first sliders 10 are engaged in the first sliding groove 9 and can slide along the first sliding groove 9. The two ends of the connecting rod 11 are rotatably connected to the two first sliders 10 respectively. The length of the connecting rod 11 is adjustable. The clamping member 12 is disposed on the first sliders 10. The clamping member 12 includes a support rod 13 and a clamp 14. The support rod 13 extends toward the window opening. The clamp 14 is used to clamp the window frame 29. The clamp 14 includes a base plate and two clamping arms. The base plate is connected to the support rod 13. The two clamping arms are disposed opposite to each other on the base plate. The clamping opening formed by the two clamping arms faces the side of the window opening. In the clamping state, the base plate abuts against the inner circumferential surface of the window frame 29, and the two clamping arms abut against the inner surface of the window frame 29 and the outer surface of the window frame 29 respectively. At least one of the main uprights 5 or the secondary uprights 6 is provided with a second sliding groove; the kick plate 8 includes a second slider 16 and a baffle 17, the second slider 16 is engaged in the second sliding groove and can slide along the second sliding groove, the baffle 17 is connected to the second slider 16, and a support plate 18 is also provided on the baffle 17, the load-bearing surface of the support plate 18 is parallel to the bottom edge of the baffle 17, and the width of the support plate 18 protruding from the surface of the baffle 17 is adjustable.

[0036] In this embodiment, the guardrail body 1, in addition to its function as an edge protection component, also serves as a transport carrier and positioning fixture for the window frame 29. The specific implementation process and principle are as follows: Firstly, the window frame 29 is loaded and pre-constrained in an avoidance state. When the guardrail body 1 rotates around the hinge base 2 towards the interior of the building and rests against the interior floor, the original protective plane of the guardrail body 1 changes from vertical to horizontal. The top horizontal guardrail 4 and its auxiliary guardrail 7, the bottom kick plate 8 and its supporting plate 18 all turn to a flat position and are on the same upward working surface. At this time, the window frame 29 to be installed is placed flat on this working surface, so that the inner circumferential surface of the window frame 29 is held in the clamp 14 of the clamping member 12, forming a bottom plate abutting against the inner circumferential surface of the window frame 29, and the two clamping arms clamp the surfaces of the window frame 29 facing inward and outward from both sides in a clamping and constraining state; at the same time, the bottom surface of the window frame 29 abuts against the load surface of the supporting plate 18, and the supporting plate 18 provides bottom support for the window frame 29. Thus, the window frame 29 is constrained into place by the clamping member 12 and the bearing plate 18 when the guardrail body 1 is laid flat. The entire loading operation is completed on the horizontal plane, eliminating the need for manual support and alignment at the edge of the opening. The operation is stable, with low labor intensity and high safety.

[0037] Secondly, the window frame 29 is transported and erected by flipping the guardrail body 1. After the window frame 29 is loaded and secured in place, the guardrail body 1 is flipped in the opposite direction around the rotation axis of the hinge base 2, changing it from an avoidance state to a protective state. During the flipping process, the window frame 29 moves synchronously with the guardrail body 1 under the clamping action of the clamping member 12 and the lifting action of the bearing plate 18, gradually changing from a horizontal position to a vertical position, and is delivered to the position facing the window opening. This process combines the handling, flipping, erection and positioning of the window frame 29 into a single flipping action, eliminating high-risk procedures such as manual lifting, flipping and edge delivery, and also avoiding the risk of the window frame 29 tipping over and falling to the outside due to instability at the edge.

[0038] Thirdly, the bottom elevation of the window frame 29 is controlled based on the load-bearing surface of the support plate 18. After the guardrail body 1 is rotated to the protective state, the load-bearing surface of the support plate 18 returns to a horizontal supporting surface, and the bottom surface of the window frame 29 always sits on it. Therefore, the bottom elevation of the window frame 29 is determined based on the load-bearing surface of the support plate 18. (It should be noted that since the second slider 16 can slide along the second slide groove, the height position of the support plate 18 can be precisely adjusted and locked, thereby quantitatively controlling the bottom elevation of the window frame 29); for each window opening on the same floor and the same facade, the position of the support plate 18 only needs to be set at the same elevation to ensure the consistency of the bottom elevation of each external window, avoiding the accumulation of errors and loss of efficiency caused by measuring and leveling each window individually.

[0039] Fourth, the installation axis of the window frame 29 is adjusted by sliding the auxiliary railing 7. Since the two first sliders 10 are engaged in the first slide groove 9 and can slide along it, and the clamping member 12 is set on the first slider 10 with its clamp 14 holding the window frame 29, pushing the auxiliary railing 7 along the first slide groove 9 in the protective state can drive the clamped window frame 29 to move as a whole along the width direction of the window opening, thereby realizing the adjustment of the installation axis of the window frame 29, so that the central axis of the window frame 29 is precisely aligned with the design axis of the window opening; at the same time, the length of the connecting rod 11 is adjustable, so that the distance between the two first sliders 10 is adapted to the width of the window frame 29, ensuring that the clamping members 12 on both sides are symmetrically stressed and synchronously displaced, and preventing the window frame 29 from twisting during the axis adjustment process.

[0040] Therefore, this embodiment controls the vertical elevation of the window frame 29 through the bearing plate 18 and controls the horizontal axis of the window frame 29 through the sliding of the auxiliary railing 7, forming a positioning system that is adjustable in both vertical and horizontal directions. This allows the window frame 29 to obtain a stable and accurate temporary position before the caulking and fixing plates are installed. Workers no longer need to manually support the window frame 29 and perform alignment at the same time. They only need to make minor checks on the established benchmark, which significantly reduces the difficulty of installing the exterior window and improves the installation accuracy and construction efficiency.

[0041] As a preferred embodiment, based on the above method, the first slider 10 and the first slide groove 9 are further provided as a separable connection; the second slider 16 and the second slide groove are also provided as a separable connection.

[0042] Specifically, the ends of the first slide 9 and the second slide 9 can be set as open, so that the first slider 10 and the second slider 16 can be directly inserted or withdrawn from the end or entrance section, thereby realizing the overall assembly and disassembly of the auxiliary railing 7 and the kick plate 8.

[0043] Therefore, both the auxiliary railing 7 and the kick plate 8 are optional and reusable independent components: they can be installed and used in window openings where height protection and auxiliary support for the window frame 29 are required, and can be removed and reused in window openings where they are not needed, thus improving the versatility of the invention in actual construction and use.

[0044] Example 3: As Figures 4 to 6 As shown, the present invention discloses a detachable permanent-temporary combined building edge protection railing structure. Further, based on the above-described method, the baffle 17 is provided with an adjusting bolt 19, which is threadedly connected to the baffle 17. The adjusting bolt 19 also has a sliding tube 20 and a locking nut 21 on its shaft. The sliding tube 20 and the adjusting bolt 19 are coaxially slidingly connected. The sliding tube 20 is connected to the bearing plate 18. The locking nut 21 is threadedly connected to the adjusting bolt 19 and abuts against the sliding tube 20, locking the sliding connection between the sliding tube 20 and the adjusting bolt 19. The baffle 17 is also provided with a limiting slot 22, the size of which matches the size of the load-bearing surface of the bearing plate 18. The limiting slot 22 allows the bearing plate 18 to pass through.

[0045] Specifically, in this embodiment, when it is necessary to increase the width of the bearing plate 18 protruding from the surface of the baffle 17, first loosen the locking nut 21 so that the locking nut 21 is away from the sliding tube 20. At this time, the sliding tube 20 slides along the rod of the adjusting bolt 19 towards the side closer to the baffle 17. After adjusting to the required width, tighten the adjusting bolt 19 so that both ends of the sliding tube 20 are respectively pressed against the adjusting bolt 19 and the locking nut 21. When it is necessary to decrease the width of the bearing plate 18 protruding from the surface of the baffle 17, first loosen the adjusting bolt 19 and slide the sliding tube 20 along the rod of the adjusting bolt 19 away from the baffle 17. After reaching the position, tighten the locking nut 21 to press and lock the sliding tube 20 against the baffle 17. This structure realizes stepless adjustment of the protrusion width of the bearing plate 18, with continuous adjustment range, high precision, and reliable locking.

[0046] Furthermore, one side of the support plate 18 is inserted into the limiting slot 22, and the slot wall of the limiting slot 22 constrains the support plate 18 in both the vertical and rotational directions. Thus, when the support plate 18 is under load, it no longer relies solely on the connection point with the sliding tube 20 of the rapid-fire gun to bear the bending moment. Instead, the limiting slot 22 provides additional vertical support and rotational constraint, forming a two-point support force system. This significantly improves the load-bearing capacity and operational stability of the support plate 18, preventing it from sagging or overturning under the weight of the window frame 29.

[0047] As a preferred embodiment, based on the above method, the adjusting bolt 19 is further provided to pass through the baffle 17, and the distance between the axis of the adjusting bolt 19 and the surface of the bearing plate 18 is less than the thickness of the window frame 29.

[0048] In this embodiment, the adjusting bolt 19 is configured to pass through the baffle 17, with its end extending from the baffle 17 toward the window opening and located above the load-bearing surface of the support plate 18. The distance between the axis of the adjusting bolt 19 and the surface of the support plate 18 is less than the thickness of the window frame 29. When the guardrail body 1 is in a clearance state and the window frame 29 is loaded and pre-constrained, the end of the adjusting bolt 19 can abut against the lower frame of the window frame 29 for support, preventing the bottom of the window frame 29 from tilting toward the baffle 17 during the flipping process of the guardrail body 1. Combined with the support plate 18 for lifting the window frame 29, the constraint stability of the window frame 29 during the flipping process is further improved.

[0049] As a preferred embodiment, based on the above method, the end of the adjusting bolt 19 is further provided with a pad 23, which is made of elastic rubber material.

[0050] Example 4: Figure 8 and Figure 9 As shown, the present invention discloses a detachable permanent-temporary combined building edge protection railing structure. Based on the above-described method, further, the bearing plate 18 includes a main plate 24 and a folding plate 25. The sliding tube 20 is connected to the main plate 24, and the folding plate 25 and the main plate 24 are rotatably connected. The main plate 24 and the folding plate 25 have a first mating configuration and a second mating configuration. In the first mating configuration, the folding plate 25 is inserted into the limiting slot 22, at which time the main board 24 and the folding plate 25 are on the same plane; In the second mating configuration, the motherboard 24 is inserted into the limiting slot 22, at which time the folding plate 25 flips downward and tilts to form an angled mating with the motherboard 24.

[0051] In this embodiment, the main board 24 and the folding plate 25 are rotatably connected via hinges, pins, or hinges. The support plate 18 is composed of the relatively rotatable main board 24 and folding plate 25, and can switch between two mating configurations depending on the working state of the guardrail body 1, respectively meeting the different needs of auxiliary installation of the window frame 29 and edge protection. Specifically: The first engagement configuration is used for the stable support of the window frame 29: When the guardrail body 1 is in an avoidance state and the window frame 29 is being loaded and pre-constrained, the main plate 24 and the folding plate 25 are adjusted to the first engagement configuration. The folding plate 25 is inserted into the limiting slot 22, and the main plate 24 and the folding plate 25 are coplanar, forming a flat, continuous, and relatively wide load-bearing surface to ensure stable support of the window frame 29; The second mating configuration is used for edge protection before window installation: Before window installation, the guardrail body 1 is in a protective state, serving as the edge protection function for the window opening. At this time, the window opening is open. The main board 24 and the folding plate 25 are adjusted to the second mating configuration. The main board 24 is inserted into the limiting slot 22, and the folding plate 25 is tilted downwards and abuts against the bottom of the window opening. This has two functions: Firstly, it repairs the bottom of the window opening. There is a gap between the bottom edge of the baffle 17 and the windowsill, through which loose items such as tools, bolts, mortar blocks, and scraps of profiles can easily slip to the outside. The folding plate 25 folds down to cover this gap, forming a continuous top-to-bottom sealing barrier with the baffle 17 to prevent objects from falling from a height.

[0052] Secondly, it guides rainwater to drain out. Before the exterior window is installed, the opening is open, and rainwater can easily flow in and flow into the room along the windowsill. The downward-sloping folding plate 25 forms a guiding slope facing outwards. Rainwater is drawn out by gravity along the slope and drained outdoors, blocking the path of rainwater inflow, preventing water accumulation indoors, and ensuring the construction environment and work safety at the opening.

[0053] Example 5: Figures 9 to 13 As shown, the present invention discloses a detachable permanent-temporary combined building edge protection railing structure. Further, based on the above-described method, the baffle 17 includes a main plate 26 and two limiting plates 27. The main plate 26 is connected to the second slider 16. The limiting plates 27 are disposed at the lower part of the main plate 26. The limiting slot 22 is disposed at the junction of the main plate 26 and the limiting plates 27. The limiting plates 27 and the main plate 26 are rotatably connected. The rotation axis of the limiting plates 27 is parallel to the side of the main plate 26, and the rotatable angle of the limiting plates 27 is greater than or equal to 90°, allowing the limiting slot 22 to release the constraint on the bearing plate 18.

[0054] In the above embodiment, the removal of the support plate 18 after the window frame 29 is installed in the window opening can only be achieved by the sliding engagement of the adjusting bolt 19 and the sliding tube 20. That is, first loosen the adjusting bolt 19, then tighten the locking nut 21 to push the sliding tube 20 to slide away from the baffle 17 until the support plate 18 is completely removed from the bottom of the window frame 29. This method has two drawbacks: First, the window frame 29 is fixed in the window opening, and the space between it and the guardrail body 1 is fixed. The construction space for workers to tighten the locking nut 21 and the adjusting bolt 19 is extremely narrow, making the operation time-consuming and laborious. Second, the support plate 18 always remains in contact with the bottom of the window frame 29 and slides relative to it during the removal process. The friction between the two can easily scratch the surface or coating of the lower frame profile of the window frame 29, causing damage to the window frame 29.

[0055] In this embodiment, the limiting slot 22 is located at the junction of the main body plate 26 and the limiting plate 27, and the limiting plate 27 and the main body plate 26 are rotatably connected with a rotatable angle greater than or equal to 90°. Therefore, by rotating the limiting plate 27, the constraint of the limiting slot 22 on the folding plate 25 can be released. Accordingly, the operation of the bearing plate 18 disengaging from the bottom of the window frame 29 can be performed as follows: First, rotate the limiting plate 27 to disengage it from the range of the bearing plate 18. At this time, the limiting slot 22 no longer constrains the folding plate 25. Under its own gravity, the folding plate 25 rotates downward around the rotational connection between itself and the main board 24, forming a second mating form with the main board 24. The bonding relationship between the bearing plate 18 and the bottom of the window frame 29 is released. Subsequently, the entire guardrail body 1 is flipped over to change its protective state to an avoidance state. During this flipping process, the folding plate 25 continues to rotate with the posture change of the guardrail body 1, that is, the cooperation angle between the folding plate 25 and the main plate 24 gradually decreases, and the folding plate 25 gradually detaches from the bottom of the window frame 29 under the pull of the guardrail body 1.

[0056] Therefore, the removal of the support plate 18 does not require tightening the locking nut 21 and adjusting bolt 19 in a confined space. It can be completed in one go by simply rotating the limiting plate 27 and flipping the guardrail body 1. The operation space is ample and the action is simple. At the same time, the downward droop of the folding plate 25 and the flipping of the guardrail body 1 cause the support plate 18 to be removed by disengagement rather than sliding, avoiding friction between the support plate 18 and the bottom of the window frame 29, and effectively protecting the surface and coating of the window frame 29 profile from damage.

[0057] It should be further explained that the method of rotating the limiting plate 27 and flipping the guardrail body 1 to make the bearing plate 18 detach itself is suitable for situations where the gap between the bottom of the window frame 29 and the window opening is relatively large. If the gap is too small, during the overall flipping of the guardrail body 1, the folding plate 25 may be stuck by the lower frame of the window frame 29 and the bottom structure of the window opening, and cannot continue to rotate with the posture change of the guardrail body 1. In this case, the folding plate 25 will be stuck in the gap and cannot be removed.

[0058] To address this issue, the problem can be solved by rotating the guardrail body 1 and using the sliding engagement of the adjusting bolt 19 and the sliding tube 20: loosen the adjusting bolt 19, then tighten the locking nut 21 to push the sliding tube 20 away from the baffle 17, causing the bearing plate 18 to move backward as a whole, and finally causing the folding plate 25 to be removed from the clamping part.

[0059] In this situation, the guardrail body 1 has been rotated at a certain angle, and the operating space between it and the window frame 29 has been significantly expanded compared to the protected state. Workers are no longer restricted by the narrow space when tightening the adjusting bolt 19 and the locking nut 21. The operating line of sight and the conditions for applying force are improved, which is still conducive to the construction of workers. At the same time, the bearing plate 18 has been separated from the bottom of the window frame 29 due to the tilt of the guardrail body 1 during the retraction process, and the contact pressure has been greatly reduced. Even if there is local contact, it will not cause scratches to the surface of the window frame 29 profile.

[0060] Therefore, this embodiment provides feasible withdrawal methods for both situations where the reserved gap is sufficient and the gap is too small. Both are based on the premise that the rotation of the limiting plate 27 releases the constraint of the limiting slot 22 on the folding plate 25, and the operation space is expanded by the flipping of the guardrail body 1, so that the bearing plate 18 can be withdrawn conveniently and safely under various window conditions.

[0061] As a preferred embodiment, based on the above method, the limiting plate 27 is further provided with a hanging hole 28.

[0062] In this embodiment, the hook hole 28 can form a reliable rotation force application point, which makes it easy for construction personnel to apply rotational torque to the limiting plate 27 through hooks, crowbars or special tools, so as to achieve its rapid and labor-saving rotation.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
