[0002] At present, after the construction of the main structure facade, temporary edge protection needs to be set up at the position of the window openings on the facade using scaffolding steel pipes. Generally, φ36 steel pipes are used, and three horizontal pipes and two vertical pipes are connected by fasteners and obliquely placed inside the openings. This structure is easily damaged after erection, making it difficult to ensure edge safety; in addition to the uncertainty of the secondary structure penetration time and the main structure construction period in the project, a large number of steel pipes are stranded, resulting in additional rental fees. Using steel pipes as facade openings has the problems of high labor costs for erection, demolition and transportation of steel pipes, inconvenient construction, and inability to quickly turnover, which brings inconvenience to people.

The "field" - shaped metal square tube skeleton and the wire mesh panel form a movable door leaf that can rotate along the metal hinge, and mounting holes are processed on the crossbar. When this structure is used, due to structural defects, it is necessary to fix the protection door from the outside, which is rather troublesome in construction. At the same time, the protection door cannot be lifted. When used in the same building, it mostly relies on manual labor to stabilize the protection door, which is rather troublesome in operation and has low construction efficiency.

[0011] Furthermore, pin holes are provided at the two extreme positions of the notch, and elastic pins are provided on the baffle. The elastic pins can enter the pin holes and disengage from the pin holes after being subjected to force.

[0012] Furthermore, a reinforcement structure is provided inside the opening. The reinforcement structure includes an embedded plate, a bracket, and reinforcement bolts.

The hanging ring is set on the frame, the embedded plate is fixed to the floor slab, and the two ends of the reinforcement rope are connected to the embedded plate and the hanging ring.

[0014] A construction method for a facade opening protection system that can be quickly reusable includes the following steps;

[0015] Step 1: Drill fixing holes

[0016] Appropriate fixing holes are made on both sides of the facade opening, with the two sides of the fixing holes on the same horizontal line;

[0017] Step 2, make the limiting hole

[0018] A limiting hole is made on the outside of the fixing hole, and a limiting rod is fixed in the limiting hole. A limiting seat is fixed on the limiting rod. The limiting seat has a limiting groove with the opening facing downward. The limiting groove has a limiting slope that gradually slopes from bottom to top and from outside to inside.

[0019] Step 3, Adjust the basic protection unit

[0020] Select the corresponding basic protection unit, adjust the adjustment seat on the upper part of the basic protection unit and fix it so that the position of the adjustment seat matches the position of the fixing hole of the basic protection unit; a limit block is fixed on the side of the basic protection unit and the limit block matches the limit groove.

[0021] Step 4: Suspend the foundation protection unit

[0022] Hook the anti-detachment hook on the basic protection unit with the hanging ring on the hoist traction rope and lift it; as the lifting proceeds, the limit block can enter the limit groove. The limit block has an inclined surface that matches the limit inclined surface, and as the frame moves upward, the position of the frame can be determined from both sides; and after stabilization, the fixing holes on the fixing plate correspond to the fixing holes on the wall.

[0023] Step 5: Secure the fastening screw.

[0024] Insert the fastening screw into the inside of the facade opening and thread it onto the fastening nut mounted on the fixing plate. Tighten the screw to fix the fixing plate to both sides of the facade opening.

[0025] Step Six: Further Reinforcement

[0026] Based on the size of the opening, reinforcement is carried out from the bottom of the basic protection unit. The reinforcement structure includes an embedded plate, a bracket, and reinforcement bolts. The embedded plate is fixed to the floor slab, the bracket is fixed to the embedded plate, and the bracket and frame are provided with corresponding reinforcement holes. The reinforcement bolts are assembled in the reinforcement holes.

[0027] Step 7, reuse

[0028] At level N-3, attach the anti-detachment hook on the basic protection unit to the ring of the wire rope of the lifting device. After it is lifted to the height of the pre-reserved fixing hole in the structure, fix it to the fixing plate with bolts, and attach the anti-detachment hook of the basic protection unit from the lifting rope to the safety rope ring / traction rope. Before the climbing frame is lifted, attach the protection used on level N-4 to the lifting device, and repeat the cycle.

[0029] Before the construction of the bottom facade opening, the bottom protective unit is hung on the ring of the lifting wire rope by the safety rope. After the construction is completed, the fastening bolts are unscrewed from the room to release the fixed state of the basic protective unit. The hoist on the climbing frame is started to lift the bottom protective unit to the N-3 floor and fix it. This process is repeated until the construction of the facade opening is completed. The protective unit is then transported to the ground by the lifting rope.

[0030] The beneficial effects of the above technical solution are:

[0031] 1. It can replace traditional steel pipe scaffolding for edge protection, ensuring construction safety, easy installation, and fast construction speed. At the same time, it reduces the rental period of steel pipes, reduces personnel and cost investment, and improves construction efficiency.

[0032] 2. Improve turnover rate by using lifting machinery to reduce the time spent on manual handling and installation of steel pipes, thereby enabling rapid turnover of facade opening edge protection units and reducing the time of missing opening protection.

[0033] 3. Construction can be carried out from the outside of the opening by using fastening screws and fastening nuts arranged on the foundation protection unit. The operation is convenient and easy to carry out. The foundation protection unit is fixed by using the self-locking of the threads.

[0034] 3. Through the structure of limiting seats and limiting blocks, the basic protection unit can be limited in the limiting seats on both sides as it is lifted, so that the basic protection unit is close to the outer wall of the opening and its position is limited. Without manual operation, the position of the fixing plate can be aligned with the reserved fixing hole, which is convenient for workers to fix from inside the opening and provides convenience for people.

[0035] 4. By combining lifting machinery and basic protection units, the amount of steel pipes used and the number of workers are greatly reduced. Construction is convenient, environmentally friendly, resource-saving, cost-reducing, and construction efficiency is improved. It can be used for the protection of various high-rise facade openings in the field of building construction technology.

[0036] In summary, this invention discloses a facade opening protection system that can be quickly rotated, applicable to the field of building construction technology, especially for the edge protection of facade openings during the construction of high-rise main structures. It does not require consideration of the erection time of steel pipes at the edge openings, nor does it require consideration of the safety of edge opening protection. Moreover, it is simple to operate and can be quickly rotated along with the progress of the main construction, changing the traditional static edge opening protection system.

Detailed Implementation

[0049] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0050] Example 1: This example aims to provide a facade opening protection system that can be quickly rotated. It is mainly applicable to the edge protection of facade openings during the construction of high-rise main structures. It does not require consideration of the erection time of steel pipes at the edge opening, nor does it require consideration of the safety of the edge opening protection. It is also simple to operate and can be quickly rotated according to the progress of the main construction. In view of the problems of existing protection systems, which require fixing the protective door from the outside, the construction is relatively troublesome. At the same time, the protective door cannot be lifted. When used in the same building, it mostly relies on manual stabilization of the protective door, which is cumbersome and has low construction efficiency. This example provides a facade opening protection system that can be quickly rotated, changing the traditional static edge opening protection system.

[0051] like Figure 1-9 The image shows a facade opening protection system for rapid turnover, comprising a basic protection unit, a lifting unit, and a fixing unit. The basic protection unit includes a frame and a protective net, with the protective net 2 installed inside the frame 1. In the specific structure, the basic protection unit is selected according to the size of the facade opening in the drawings before the main construction. The basic protection unit can be a stainless steel frame / iron product / aluminum product, and the protective net can be a safety net or wire mesh. Anti-detachment hooks are installed on the frame, and the overall size is adapted to the width of the opening.

[0052] like Figure 3-4 As shown, the lifting unit includes a hoist, a lifting rope 8, a hook 9, and a hanging ring. The hoist is fixedly installed on the climbing frame and is lifted synchronously with the climbing frame. The lifting rope is arranged on the hoist, the hook 9 is fixed on the frame 1, and the hanging ring is fixed on the lifting rope and is adapted to hook onto the hanging ring 9. During the installation of the climbing frame on the exterior facade, a lifting device for the protective system is installed. The lifting device has a hoist and two sets of sufficiently long steel wire ropes / guide chains with rings (one set for lifting and one set for safety rope 81). The lifting device can be installed on the climbing frame using a winch or electric guide chain and is lifted synchronously with the climbing frame.

[0053] like Figure 2 As shown, the fixing unit includes a fixing plate 5, a fastening nut 6, and a fastening bolt 7. Fixing holes 10 are provided at corresponding positions on both sides of the facade opening. The fixing holes 10 penetrate the wall, and the fastening nut 6 is provided on the fixing plate 5. The fastening nut 6 corresponds to the fixing hole 10. The fastening bolt 7 is applied to the inside of the opening and screwed onto the fastening nut 6 through the fixing hole 10. The fixing plate 5 is fastened to the outer wall of the facade opening by using the limiting part arranged on the fastening bolt and the limiting nut. In specific implementation, the limiting part is a nut fixed to the end of the fastening bolt 6 or a limiting plate fixed to the middle or end of the fastening bolt. The fastening structure is formed by the limiting plate and the external threaded connection, thus fixing the fixing plate to the outer wall.

[0054] To ensure that the fixing plate 5 and the frame 1 can be tightly attached to the exterior wall, the fixing plate 5 is fixed to the inner side of the frame 1. When the fixing plate is tightly attached to the exterior wall, the frame can also be tightly attached to the exterior wall to ensure the fixing effect.

[0055] This embodiment aims to stabilize the basic protection unit for smaller openings by using a two-point method. The lifting device facilitates the lifting of the structure to a specific height, and the fixing relationship is applied from inside the opening. It has good performance in multi-story building construction. 1. It can replace the edge protection of traditional steel pipe scaffolding, ensuring construction safety, convenient installation, and fast construction speed. At the same time, it reduces the rental period of steel pipes, reduces personnel and cost investment, improves construction efficiency, and increases turnover rate. By using lifting machinery, it reduces the time spent on manual handling and installation of steel pipes, enabling rapid turnover of facade opening edge protection units and reducing the time of missing opening protection.

[0056] Example 2 further illustrates the structure of the adjustment seat.

[0057] In this embodiment, as shown... Figure 1-2 As shown, an adjusting rod 3 is provided on the frame, a fixing plate 5 is fixed on the adjusting seat 4, and the adjusting seat 4 is slidably fitted on the adjusting rod 3.

[0058] In this embodiment, the adjusting seat 4 is arranged on the adjusting rod 3, which allows the position of the adjusting seat to be adjusted, thereby allowing the position of the fixing plate 5 to be adjusted, facilitating the correspondence between the holes on the fixing plate 5 and the fixing holes 10, and making adaptive adjustments according to the on-site construction environment. The fixing method of this adjusting seat is to lock it after fixing, and the locking method is to lock it with the set screw on the side, so as to determine the position of the fixing plate.

[0059] Example 3: This example further provides a limiting structure for the positioning of the basic protection unit, enabling it to automatically position itself at the fixed hole during the lifting process, which facilitates the construction of the basic protection unit. At the same time, the addition of a limiting structure in the middle area improves the stability of the basic protection unit.

[0060] This implementation example Figure 10 A limiting hole is also provided on the outside of the fixing hole. As an implementation method, the limiting hole is opened on the lower part of the outside of the fixing hole, and a limiting rod 19 is installed in the limiting hole. A limiting seat 20 is fixed on the limiting rod 19. The limiting seat 20 has a limiting groove 21 with the opening facing downward. The limiting groove 21 has a limiting inclined surface 22 that gradually slopes from bottom to top and from outside to inside. A limiting block 18 is fixed on the side of the frame 1. The limiting block 18 is adapted to the limiting groove 21 and can enter the limiting groove 21. The limiting block 18 has an inclined surface that is adapted to the limiting inclined surface 21, and as the frame moves upward, the position of the frame can be determined from both sides.

[0061] This method is suitable for one-to-one construction, meaning it corresponds to construction of only one inner opening. During the lifting process, the basic protection unit is automatically embedded into the limiting groove. The inclined surface is used to simultaneously position the basic protection unit on both sides to determine its position. As it is lifted, the basic protection unit is limited in the limiting seats on both sides, so that the basic protection unit is close to the outer wall of the opening and its position is limited. Without manual operation, the position of the fixing plate can be aligned with the reserved fixing hole, which is convenient for workers to fix from inside the opening and provides convenience for people.

[0062] In a further implementation of the structure, the limiting groove also has a second inclined surface, which faces the front of the limiting block. The structure is similar to the limiting inclined surface 21, thereby performing secondary positioning on the front. The limiting groove has a large opening to facilitate the end of the limiting block to enter into it, and after entering, it is limited from both the side and front of the limiting block.

[0063] Example 4: This example mainly addresses the problems existing in Example 3 by providing a positioning structure with multiple openings.

[0064] In the specific structure, such as Figure 11 As shown in the figure, a fixed sleeve is fixed inside the limiting hole, and the limiting rod is rotatably fitted inside the fixed sleeve. A limiting piece 23 is provided on the outside of the fixed sleeve, and a baffle 24 is provided on the limiting rod 23. The limiting piece has a notch, and the baffle can swing at a certain angle within the notch.

[0065] Pin holes 26 are provided at the two extreme positions of the notch, and elastic pins 25 are provided on the baffle. The elastic pins 25 can enter the pin holes 26 and disengage from the pin holes after being subjected to force. The elastic pins are similar to spring clips. After being subjected to increased load, they can overcome their elasticity and disengage from the pin holes. The edge of the pin hole structure can be arranged with guides as needed. In terms of force, when the pin is in the right position, the limiting seat is in use and the load from the basic protection unit is upward and is borne by the limiting plate.

[0066] This structure allows the limiting seat to have both a usable and a non-usable state. In the usable state, it allows the limiting block to enter and provides corresponding obstruction. In the non-usable state, the limiting seat and the frame are misaligned and do not provide any obstruction, thus facilitating the movement of the corresponding basic protection unit to the corresponding opening.

[0067] Example 5: This example further illustrates the reinforcement structure of the basic protection unit based on the size of the opening.

[0068] This embodiment mainly addresses situations where the opening is too large, and the reinforcement provided on the basic protection unit in Embodiments 1 and 2 is insufficient to meet the fixing requirements. In this embodiment, a further reinforcement structure is added to the lower part.

[0069] like Figure 9 As shown, a reinforcement structure is also provided inside the opening. The reinforcement structure includes an embedded plate 15, a bracket 16, and reinforcement bolts 17. The embedded plate 15 is fixed to the floor slab, the bracket 16 is fixed to the embedded plate 15, and the bracket and frame are provided with corresponding reinforcement holes. The reinforcement bolts 17 are assembled in the reinforcement holes.

[0070] like Figure 6-8 As shown in the figure, or as described, a reinforcement structure is also provided in the opening. The reinforcement structure includes an embedded plate 15, a reinforcement rope 13, and a hanging ring 11. The hanging ring 11 is provided on the frame 1. The embedded plate 15 is fixed to the floor slab by a collision bolt 12. The two ends of the reinforcement rope are connected to the embedded plate and the hanging ring, one end is connected to the hanging ring 11, and the other end is fixed to the fixing point 14.

[0071] If the opening is too wide, it can be connected by a snap-fit ​​adjustment device, and additionally fixed by either method one or method two of unit extension anchoring to ensure the overall rigidity and safety of the combined protective unit. Method one uses a safety rope / wire rope to tighten the protective unit, while method two uses a square tube and the protective unit to be connected by bolts. The square tube has pre-drilled bolt holes, and the protective unit frame has pre-drilled bolt holes and is welded with double nuts. Both methods require anchoring to the structural plate with expansion bolts and pads.

[0072] This embodiment can further reinforce the basic protection unit from below, ensuring the stability of the basic protection unit, and is suitable for larger openings.

[0073] Based on the above embodiments, the present invention also provides a construction method, the details of which are as follows;

[0074] A construction method for a facade opening protection system that can be quickly reusable includes the following steps;

[0075] Step 1: Drill fixing holes

[0076] Appropriate fixing holes are made on both sides of the facade opening, with the two sides of the fixing holes on the same horizontal line;

[0077] Step 2, make the limiting hole

[0078] A limiting hole is made on the outside of the fixing hole, and a limiting rod is fixed in the limiting hole. A limiting seat is fixed on the limiting rod. The limiting seat has a limiting groove with the opening facing downward. The limiting groove has a limiting slope that gradually slopes from bottom to top and from outside to inside.

[0079] Step 3, Adjust the basic protection unit

[0080] Select the corresponding basic protection unit, adjust the adjustment seat on the upper part of the basic protection unit and fix it so that the position of the adjustment seat matches the position of the fixing hole of the basic protection unit; a limit block is fixed on the side of the basic protection unit and the limit block matches the limit groove.

[0081] Step 4: Suspend the foundation protection unit

[0082] Hook the anti-detachment hook on the basic protection unit with the hanging ring on the hoist traction rope and lift it; as the lifting proceeds, the limit block can enter the limit groove. The limit block has an inclined surface that matches the limit inclined surface, and as the frame moves upward, the position of the frame can be determined from both sides; and after stabilization, the fixing holes on the fixing plate correspond to the fixing holes on the wall.

[0083] Step 5: Secure the fastening screw.

[0084] Insert the fastening screw into the inside of the facade opening and thread it onto the fastening nut mounted on the fixing plate. Tighten the screw to fix the fixing plate to both sides of the facade opening.

[0085] Step Six: Further Reinforcement

[0086] Based on the size of the opening, reinforcement is carried out from the bottom of the basic protection unit. The reinforcement structure includes an embedded plate, a bracket, and reinforcement bolts. The embedded plate is fixed to the floor slab, the bracket is fixed to the embedded plate, and the bracket and frame are provided with corresponding reinforcement holes. The reinforcement bolts are assembled in the reinforcement holes.

[0087] Step 7, reuse

[0088] At level N-3, attach the anti-detachment hook on the basic protection unit to the ring of the wire rope of the lifting device. After it is lifted to the height of the pre-reserved fixing hole in the structure, fix it to the fixing plate with bolts, and attach the anti-detachment hook of the basic protection unit from the lifting rope to the safety rope ring / traction rope. Before the climbing frame is lifted, attach the protection used on level N-4 to the lifting device, and repeat the cycle.

[0089] Before the construction of the bottom facade opening, the bottom protective unit is hung on the ring of the lifting wire rope by the safety rope. After the construction is completed, the fastening bolts are unscrewed from the room to release the fixed state of the basic protective unit. The hoist on the climbing frame is started to lift the bottom protective unit to the N-3 floor and fix it. This process is repeated until the construction of the facade opening is completed. The protective unit is then transported to the ground by the lifting rope.

[0090] This invention optimizes traditional steel pipe scaffolding into a complete set of mobile foundation protection units, while maintaining its functionality. It is simple to operate, reliably and securely installed, and improves construction safety at openings near edges. By combining lifting machinery and foundation protection units, the amount of steel pipes used and the number of workers required are significantly reduced. Construction is convenient, environmentally friendly, resource-saving, cost-effective, and efficient. It can be used for the protection of various high-rise building facade openings in the field of building construction technology.

Step Six: Further Reinforcement Based on the size of the opening, reinforcement is carried out from the bottom of the basic protection unit. The reinforcement structure includes an embedded plate, a bracket, and reinforcement bolts. The embedded plate is fixed to the floor slab, the bracket is fixed to the embedded plate, and the bracket and frame are provided with corresponding reinforcement holes. The reinforcement bolts are assembled in the reinforcement holes. Step 7, reuse At level N-3, attach the anti-detachment hooks on the basic protection unit to the rings on the wire rope of the lifting device. Once the structure reaches the height of the pre-reserved fixing holes, fix it to the fixing plate with bolts. Then, attach the anti-detachment hooks of the basic protection unit from the lifting rope to the safety rope ring / traction rope. Before the climbing frame is lifted, attach the anti-detachment hooks of the protection units used at level N-4 to the rings on the wire rope of the lifting device. Repeat this process. Before the construction of the bottom facade opening, the bottom protective unit is hung on the ring of the lifting wire rope by the safety rope. After the construction is completed, the fastening bolts are unscrewed from the room to release the fixed state of the basic protective unit. The hoist on the climbing frame is started to lift the bottom protective unit to the N-3 floor and fix it. This process is repeated until the construction of the facade opening is completed. The protective unit is then transported to the ground by the lifting rope.
