Description

Technical Field

[0001] This utility model relates to the technical field of roof repair construction, and in particular to an edge protection device for repairing the pitched roof of a multi-story residential building. Background Technology

[0002] In the field of multi-story residential building maintenance, pitched roofs have become the roof design choice for many residences due to their excellent drainage performance and beautiful architectural appearance. Pitched roofs with gutters are even more widely used in practice because the gutters can efficiently collect and guide rainwater out, further reducing the risk of roof leakage. However, after long-term use, due to factors such as repeated rainwater erosion of the gutters, aging of roof materials caused by temperature changes, and failure of the seal at the junction of the gutters and the roof, problems such as roof leakage, tile damage, cracking of the waterproof layer, and blockage or corrosion of the gutters are prone to occur, requiring regular maintenance.

[0003] However, existing edge protection devices still have the following problems: Traditional protective devices mostly employ welding or dense bolt connections. Installation requires specialized tools such as welding machines and heavy-duty wrenches, and necessitates multiple personnel to assemble the frame. Disassembly requires removing bolts or cutting weld points one by one, which is not only cumbersome but also exacerbates the difficulty of installation and disassembly due to the limited working space on roofs with gutters, severely impacting the progress of repair work. Furthermore, the fixing methods of existing protective devices are ill-suited to the special structure of gutters: some devices require drilling holes in the roof and using expansion bolts for fixing, which can damage the original waterproof and structural layers of the roof, especially potentially harming the sealing joint between the gutter and the roof, leading to new leakage risks; some devices rely on their own weight for restraint, but their bottoms have poor adhesion to the sloping roof and gutter surface, making them prone to sliding along the roof slope under construction vibrations and wind, or even tipping over from the edge of the gutter, failing to form a stable protective barrier. Therefore, it is necessary to provide an edge protection device for the repair of multi-story residential sloping roofs to solve the above technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an edge protection device for the repair of pitched roofs of multi-story residential buildings.

Two connecting blocks are symmetrically fixed to both sides of the protective rod. Two connecting rods are symmetrically arranged laterally between the two protective rods. The ends of the connecting rods are installed inside the connecting blocks. A protective net is installed on the surface of both the protective rod and the connecting rod. A first through groove is provided in the connecting block. A limiting groove corresponding to the first through groove is provided on the wall of the connecting rod. A housing is fixedly connected to the outer wall of the connecting block. A rotating rod is rotatably connected through the housing. An elliptical plate is fixedly connected to one end of the rotating rod inside the housing. A movable plate is slidably connected inside the housing. A limiting rod is fixedly connected to the outer wall of the movable plate. The bottom end of the limiting rod passes through the first through groove and extends into the limiting groove. A sliding rod is slidably connected inside the rotating rod. A knob is fixedly connected to one end of the sliding rod after it extends out of the rotating rod. A plug is fixedly connected to one side of the knob. A slot corresponding to the plug is provided on one side of the rotating rod. A fixing component is provided at the lower part of the protective rod.

[0006] Preferably, a first spring is provided inside the housing, one end of the first spring is fixedly connected to the inner wall of the housing, and the other end of the first spring is fixedly connected to the outer wall of the movable plate.

[0007] Preferably, there are two of each of the first through groove, the limiting groove, and the limiting rod, and they correspond one-to-one.

[0008] Preferably, L-shaped rods are fixedly connected to both sides of the interior of the housing, and a second through groove adapted to the L-shaped rod is opened through both sides of the movable plate. The movable plate is slidably connected to the L-shaped rod through the second through groove.

[0009] Preferably, the rotating rod has two symmetrically formed sliding grooves inside, and a slider is slidably connected in the sliding groove. The slider is fixedly connected to the outer wall of the sliding rod.

[0010] Preferably, a second spring is provided inside the rotating rod, one end of the second spring is fixedly connected to the inner side wall of the rotating rod, and the other end of the second spring is fixedly connected to the end of the sliding rod.

[0011] Preferably, the fixing component includes a fixing rod, which is fixedly connected to the lower outer wall of the protective rod. A bolt is threadedly connected to the bottom end of the protective rod laterally. An abutment block is fixedly connected to one end of the bolt. Two bolts are symmetrically arranged. A washer is sleeved on the outside of the bolt. The washer is a spring washer, and the inner diameter of the washer is adapted to the outer diameter of the bolt.

[0012] Preferably, the protective net is fixed to the surface of the protective rod and the connecting rod by a detachable connector, the detachable connector including a binding strap.

[0013] Compared with related technologies, the edge protection device for repairing the pitched roof of a multi-story residential building provided by this utility model has the following beneficial effects: 1. In the repair of pitched roofs, simply insert the end of the connecting rod into the corresponding connecting block, and pull the knob to move the sliding rod outward along the axis of the rotating rod, causing the insert rod to disengage from the slot on the rotating rod. This releases the knob's rotation lock. Twisting the knob will cause the rotating rod and the elliptical plate to rotate synchronously. When the elliptical plate rotates, it presses against the moving plate inside the housing. The contact area between the elliptical plate and the moving plate gradually transitions from the short axis to the long axis, compressing the first spring. At the same time, the moving plate drives the limiting rod through the first through groove and inserts it into the limiting groove. Finally, the insert rod is aligned with the slot. Release the knob and insert the insert rod into the slot. The second spring inside the rotating rod drives the sliding rod to return to its original position, allowing the insert rod to be stably inserted into the slot, thus locking the rotating rod and fixing the connecting rod. Disassembly is done by reversing the operation. The entire process requires no other professional installation tools, greatly reducing the difficulty of operation for construction personnel, improving disassembly and assembly efficiency, and facilitating assembly.

[0014] 2. Modular splicing is achieved through the cooperation of the protective rod and the connecting block. The number of protective rods, connecting blocks and connecting rods can be increased according to the needs of use. This allows the overall length and coverage area of ​​the device to be flexibly adjusted according to the actual construction range, whether it is a short-distance roof edge or a long-span edge area. This breaks the limitations of traditional fixed-size protective devices and adapts to the edge protection needs of different repair scenarios of multi-story residential pitched roofs.

[0015] 3. The rigid frame composed of the protective rod and connecting rod forms the first protective barrier. Through the tight cooperation of the limiting rod and the limiting groove, the fixing rod abuts against one side of the roof gutter, and the bolt is rotated to make the abutting block abut against the other side of the roof gutter. With the help of spring washers to reduce the risk of bolt vibration and loosening, the device is fixedly installed on the roof gutter, ensuring stable installation in the sloping environment of the roof and preventing the risk of displacement or tipping. At the same time, the clamping structure of the fixing rod and bolt can be adapted to gutter side plates of different widths, eliminating the need for additional drilling or pouring of a fixing foundation on the roof, thus improving the convenience of installation.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1 Please refer to the following: Figures 1 to 5 A protective device for edge protection of multi-story residential roof repair includes a protective rod 1. Two connecting blocks 2 are symmetrically fixed to both sides of the protective rod 1. Two connecting rods 3 are symmetrically arranged laterally between the two protective rods 1. The ends of the connecting rods 3 are installed inside the connecting blocks 2. A protective net 4 is installed on the surface of both the protective rod 1 and the connecting rods 3. A first through groove 5 is formed in the connecting block 2. A limiting groove 6 corresponding to and adapted to the first through groove 5 is formed on the wall of the connecting rod 3. A shell 7 is fixedly connected to the outer wall of the connecting block 2. A rotating rod 8 is rotatably connected inside the housing 7. An elliptical plate 9 is fixedly connected to one end of the rotating rod 8 inside the housing 7. A movable plate 10 is slidably connected inside the housing 7. A limiting rod 11 is fixedly connected to the outer wall of the movable plate 10. The bottom end of the limiting rod 11 passes through the first through groove 5 and extends into the limiting groove 6. A sliding rod 15 is slidably connected inside the rotating rod 8. A knob 16 is fixedly connected to one end of the sliding rod 15 after it extends out of the rotating rod 8. An insertion rod 17 is fixedly connected to one side of the knob 16. A slot 18 that matches the insertion rod 17 is opened on one side of the rotating rod 8.

[0020] In the above, the protective rod 1 serves as the core supporting component of the device, providing stable vertical support for the overall protective frame. The connecting block 2 acts as a bridge connecting the protective rod 1 and the connecting rod 3, achieving precise docking of the two through its internal structure. The connecting rod 3 connects the adjacent protective rod 1 laterally, forming a rigid protective frame together with the protective rod 1, providing an installation foundation for the protective net 4. The protective net 4 can effectively intercept construction waste generated during the repair of the sloping roof, while preventing construction workers from accidentally falling, forming a flexible protective barrier. The first through groove 5 provides a moving channel for the limiting rod 11. The limiting groove 6 cooperates with the limiting rod 11, and the connecting rod 3 is connected through physical locking. The connection block 2 is fixed to prevent the connecting rod 3 from falling off during use. The rotating rod 8 drives the elliptical plate 9 to rotate, providing power for the movement of the limiting rod 11. The elliptical plate 9, through the characteristics of its elliptical structure, squeezes the moving plate 10 when rotating, converting the rotational motion into the linear motion of the moving plate 10. The moving plate 10 serves as the mounting carrier for the limiting rod 11, driving the limiting rod 11 to move synchronously, realizing the docking or separation of the limiting rod 11 and the limiting groove 6. The sliding rod 15 slides along the axis of the rotating rod 8, driving the knob 16 and the insertion rod 17 to move. The insertion rod 17 cooperates with the slot 18 to lock the position of the rotating rod 8, preventing the elliptical plate 9 from accidentally rotating and causing the limiting to fail.

[0021] Furthermore, a first spring 12 is provided inside the housing 7. One end of the first spring 12 is fixedly connected to the inner wall of the housing 7, and the other end of the first spring 12 is fixedly connected to the outer wall of the movable plate 10.

[0022] In the above, the first spring 12 has an elastic reset function. When the elliptical plate 9 rotates to release the pressure on the moving plate 10, the first spring 12 can release the rebound force, push the moving plate 10 to drive the limiting rod 11 to reset, so that the limiting rod 11 is disengaged from the limiting groove 6, which facilitates the disassembly of the connecting rod 3.

[0023] Furthermore, there are two of each of the first through groove 5, the limiting groove 6, and the limiting rod 11, and they correspond one-to-one.

[0024] In the above, the corresponding arrangement of the two sets of first through grooves 5, limiting grooves 6 and limiting rods 11 can limit and fix the connecting rod 3 from two different positions. Compared with a single set structure, it can effectively disperse the external force on the connecting rod 3, avoid damage to a single limiting point due to excessive force, further improve the stability of the connection between the connecting rod 3 and the connecting block 2, and prevent the connecting rod 3 from shifting.

[0025] Furthermore, L-shaped rods 13 are fixedly connected to both sides of the interior of the housing 7, and second through slots 14 adapted to the L-shaped rods 13 are opened through both sides of the movable plate 10. The movable plate 10 is slidably connected to the L-shaped rods 13 through the second through slots 14.

[0026] In the above, the sliding engagement between the L-shaped rod 13 and the second through groove 14 can constrain the movement trajectory of the moving plate 10, prevent the moving plate 10 from tilting during the compression of the elliptical plate 9 or the reset of the first spring 12, ensure that the moving plate 10 always moves in a straight line, and thus ensure that the limiting rod 11 can be accurately aligned with the first through groove 5 and the limiting groove 6.

[0027] Furthermore, the protective net 4 is fixed to the surface of the protective rod 1 and the connecting rod 3 by detachable connectors, including cable ties.

[0028] As described above, the protective net 4 is fixed by detachable connectors such as cable ties. This facilitates the installation and replacement of the protective net 4. When the protective net 4 is damaged, the old net can be quickly removed and replaced with a new net, reducing maintenance costs. On the other hand, the cable tie connection method is flexible and can adjust the fixed position of the protective net 4 according to the frame structure of the protective rod 1 and the connecting rod 3, ensuring that the protective net 4 fully covers the protected area. At the same time, when disassembling the device, the protective net 4 can be removed first and then the frame can be disassembled, improving the flexibility of disassembly and assembly.

[0029] Example 2 For further details, please refer to [link / reference]. Figures 1 to 6 Based on Embodiment 1, two symmetrical grooves 19 are opened inside the rotating rod 8, and a slider 20 is slidably connected in the groove 19. The slider 20 is fixedly connected to the outer wall of the sliding rod 15.

[0030] In the above, the sliding fit between the groove 19 and the slider 20 can restrict the movement direction of the slide rod 15, prevent the slide rod 15 from rotating or deviating when it moves along the axis of the rotating rod 8, ensure that the slide rod 15 always moves along the axis of the rotating rod 8, prevent the slide rod 15 from falling out of the rotating rod 8, and improve the structural stability.

[0031] Furthermore, a second spring 21 is provided inside the rotating rod 8. One end of the second spring 21 is fixedly connected to the inner side wall of the rotating rod 8, and the other end of the second spring 21 is fixedly connected to the end of the slide rod 15.

[0032] In the above, the second spring 21 has an automatic reset function. When the construction worker pulls the knob 16 to move the slide bar 15 outward, the second spring 21 is compressed and stores elastic potential energy. When the knob 16 is released, the second spring 21 releases the elastic potential energy, pushes the slide bar 15 to automatically reset, and drives the insertion rod 17 to quickly insert into the slot 18. There is no need for manual pushing of the slide bar 15, which simplifies the operation steps, improves the locking efficiency of the device, and also ensures that the insertion rod 17 fits tightly with the slot 18, preventing the rotating rod 8 from rotating accidentally.

[0033] Furthermore, a fixing component is provided at the lower part of the guard rod 1. The fixing component includes a fixing rod 22, which is fixedly connected to the lower outer wall of the guard rod 1. A bolt 23 is threadedly connected to the bottom end of the guard rod 1. An abutment block 24 is fixedly connected to one end of the bolt 23. Two bolts 23 are symmetrically arranged. A washer 25 is sleeved on the outside of the bolt 23. The washer 25 is a spring washer, and the inner diameter of the washer 25 is adapted to the outer diameter of the bolt 23.

[0034] In the above-mentioned fixing components, the device can be stably fixed on the gutter of the sloping roof, ensuring that the device will not shift or tip over in an inclined environment. The fixing rod 22 in the fixing components can fit against one side of the roof gutter to provide initial support for the device. The bolt 23 drives the abutment block 24 to move through the threaded connection, so that the abutment block 24 fits tightly against the other side of the gutter. Through the clamping action of the fixing rod 22 and the abutment block 24, the device is fixed on the gutter. Moreover, the thread structure of the bolt 23 can adjust the position of the abutment block 24 according to the width of the gutter to adapt to gutter side plates of different widths. The two symmetrically arranged bolts 23 can apply force evenly from both sides to prevent the device from tilting due to excessive force on one side. The spring washer 25 is elastic and can generate continuous elastic pressure after the bolt 23 is tightened to prevent the bolt 23 from loosening due to construction vibration, ensuring that the device is stably fixed on the gutter for a long time. At the same time, the washer 25 can also reduce the friction between the bolt 23 and the protective rod 1, protecting the surface structure of the protective rod 1.

[0035] The working principle of the edge protection device for repairing the pitched roof of a multi-story residential building provided by this utility model is as follows: In the repair work of the pitched roof of a multi-story residential building, firstly, the operator inserts the end of the connecting rod 3 into the interior of the corresponding connecting block 2 to complete the initial splicing of the protective frame. Then, the operator pulls the knob 16 to move the slide rod 15 fixed to it outward along the axis of the rotating rod 8, so that the insert rod 17 on one side of the knob 16 disengages from the slot 18 on the rotating rod 8, releasing the lock on the rotation of the knob 16. At this time, turning the knob 16 can drive the rotating rod 8 to rotate synchronously. When the elliptical plate 9 rotates with the rotating rod 8, it will squeeze the slidingly connected moving plate 10 inside the housing 7. As the elliptical plate 9 rotates, the part in contact with the moving plate 10 gradually transitions from the short axis to the long axis. Since the length of the long axis of the elliptical plate 9 is greater than the short axis... The length of the long axis exerts a compressive force on the moving plate 10 along the direction "closer to the connecting block 2", causing the moving plate 10 to move closer to the connecting block 2. At the same time, the first spring 12 inside the housing 7 is compressed by the moving plate 10, and the moving plate 10 drives the limiting rod 11 to move synchronously. When the limiting rod 11 passes through the first through groove 5 and is inserted into the limiting groove 6 of the connecting rod 3, the knob 16 is released, and the second spring 21 fixed inside the rotating rod 8 releases its rebound force, driving the slide rod 15 to reset, so that the insertion rod 17 is re-inserted into the slot 18, locking the position of the rotating rod 8, realizing the stable fixation of the connecting rod 3, and thus realizing the fixed connection between the connecting rod 3 and the connecting block 2, thereby making the connecting rod 3 and the anti-corrosion... The guard rod 1 forms an integral frame. Then, the protective netting 4 is fixedly connected to the guard rod 1 and connecting rod 3 using cable ties. The number and spacing of the cable ties are selected according to actual needs. The fixing rod 22 is placed on both sides of the gutter in conjunction with the guard rod 1. By rotating the bolt 23, the abutment block 24 abuts against the gutter side plate, thus fixing the device to the gutter. The abutment block 24 fixed at one end of the bolt 23 enhances the contact stability with the gutter side plate, and the sliding gasket 25 on the surface of the bolt 23 prevents the bolt 23 from loosening due to construction vibration. Furthermore, by passing the cable ties through the mesh of the protective netting 4 and binding it to the guard rod 1 and connecting rod 3, the device is further secured. The device enhances safety and ensures safe and efficient roof repair work. The entire disassembly and assembly process requires no complex tools, significantly improving the operational efficiency of construction personnel. During device operation, the L-shaped rods 13 fixed at both ends inside the shell 7 slide in conjunction with the second through groove 14, limiting the movement trajectory of the moving plate 10 and preventing it from tilting due to uneven force. The sliding groove 19 inside the rotating rod 8 slides in conjunction with the slider 20, which can constrain the movement direction of the sliding rod 15 and prevent the sliding rod 15 from detaching from the rotating rod 8 due to excessive force when the operator pulls the knob 16. The protective net 4 intercepts construction waste generated during roof demolition and repair, avoiding the risk of falling from heights and improving safety.
