Description

Technical Field

[0001] This utility model belongs to the field of roof construction protection technology, and in particular relates to a roof construction edge protection device. Background Technology

[0002] In building construction, roofing work falls under the category of high-altitude operations, and the edge areas are high-risk areas for safety accidents. According to building construction safety regulations, effective protective facilities must be installed at roof edges to prevent workers and materials from falling or accidentally slipping. Existing edge protection devices often utilize temporary scaffolding or railings, which are complex in structure, cumbersome to install, and have limited protective effectiveness, making them unsuitable for different roof structures. Furthermore, traditional protective devices are inconvenient and inefficient to disassemble and transport, easily causing construction delays. Therefore, some existing protective devices are gradually being modularized, making assembly increasingly simple.

[0003] For example, patent application number CN215212474U discloses a roof construction edge protection device, including a main support frame. Telescopic sleeves are rotatably connected to both sides of the middle of the main support frame. Fixed bolts are threadedly connected to the connection points of the two telescopic sleeves and the main support frame. Telescopic straight pipes are slidably connected to the inner sides of one end of each of the two telescopic sleeves. Protective steel pipes are rotatably connected to one end of each of the two telescopic straight pipes. Perforated steel mesh is fixedly installed on the inner sides of each of the two protective steel pipes. This utility model provides a roof construction edge protection device and method. This protection device allows for edge-free installation, making it safer and more reliable. It can be automatically or semi-automatically moved to the construction position as needed. The prefabricated design allows for tooling and modularization, greatly increasing turnover rate. Installation and movement are fast and easy to operate. The telescopic arms can accommodate different sizes of sloping roofs, making it widely applicable.

[0004] Existing technologies, through the design of structures such as retractable rollers and telescopic sleeves, enable equipment to meet the application requirements of sloping roofs of different sizes and provide a certain level of safety protection. However, there are still some shortcomings in overall use:

[0005] Firstly, roof construction is inherently dangerous, with workers potentially falling. Secondly, the weather can be unpredictable during roof construction, with workers possibly encountering severe weather conditions such as rain or strong winds. Existing equipment may not provide a safe working environment, which could easily lead to safety accidents or delays in the construction period.

[0006] Secondly, the rooftop construction area is large, and the existing equipment is quite cumbersome to move. After workers finish a section, they need to manually move the equipment and flip it over before they can continue working, which consumes a lot of labor costs. In addition, disassembling and assembling equipment on the rooftop is also somewhat dangerous.

[0007] Finally, roof construction is usually carried out on sunny days, which are typically hot. The existing scaffolding cannot provide more comfortable construction conditions, thus affecting construction efficiency. Utility Model Content

[0008] To overcome the shortcomings of existing technologies, this invention provides a roof construction edge protection device. This invention solves the technical problems of existing devices failing to guarantee construction safety and hindering improvements in construction conditions, while simultaneously reducing the overall size of the equipment, making it easier to move, improving construction efficiency, and lowering construction costs.

Detailed Implementation

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0037] A roof construction edge protection device, see attached document. Figure 1 Appendix Figure 10 Appendix Figure 11 and attached Figure 12 The system includes a first sliding frame 11, which is slidably mounted on the outside of the crossbeam on the ridge 10. In this application, the ridge 10 refers to a roof with slopes on both sides and a crossbeam at the top of the slopes. There are protruding platforms on both sides of the slopes. The figure shows a rough model of the ridge, which is prior art and will not be elaborated on further in this solution. Supporting cross plates 47 are provided on the outer end faces of both sides of the first sliding frame 11. The supporting cross plates 47 are located outside the end faces of both sides of the crossbeam. Multiple third electric push cylinders 41 are symmetrically arranged on the end faces of the two supporting cross plates 47. The output ends of the third electric push cylinders 41 on both sides extend to the inside of the first sliding frame 11 and are connected to... The pulley groove 44 is equipped with multiple pulleys 45. Multiple second electric push cylinders 38 are provided on the three end faces of the first sliding frame 11 adjacent to the ridge. The output end of the second electric push cylinder 38 is connected to a second pressure plate 39. Multiple pressure detection units 25 are provided on the contact end face of the second pressure plate 39. The pressure detection unit 25 includes a pressure sensor 26. A spring 27 is connected to the detection end face of the pressure sensor 26. The other end of the spring 27 is connected to a pressure plate 28. The pressure plate 28 protrudes from the bottom surface of the second pressure plate 39 under the action of the spring 27. The pressure sensor 26 and the pressure plate 28 are connected through the spring 27.

[0038] Specifically, before the workers begin construction, the equipment is placed on the ridge 10. During placement, the first sliding frame 11 is placed outside the top beam of the ridge 10. At this time, the output ends of multiple second electric push cylinders 38 will push the second pressure plate 39, causing the second pressure plate 39 to abut against the outer end face of the beam. During the abutment process of the second pressure plate 39, the pressure plate 28 will also come into contact with the outside of the beam. Due to the connection of the spring 27, the pressure plate 28 will slide towards the pressure sensor 26, so that the pressure during abutment can be transmitted to the pressure sensor 26. This allows the pressure sensor 26 to detect the clamping pressure, which can help determine whether the device is effectively clamped and fixed in place, ensuring the safety of the construction personnel.

[0039] When the equipment needs to be moved on the ridge 10, multiple second electric push cylinders 38 release their clamps. At this time, the third electric push cylinder 41 pushes the pulley groove 44 and pulley 45 to abut against the outside of the crossbeam. Then the construction personnel can push the device so that the device slides and moves along the lateral direction of the ridge 10 to adjust the construction area.

[0040] Further, see attached document. Figure 1 and attached Figure 8 Two transverse fixing rods 30 are symmetrically arranged on one side of the supporting horizontal plate 47. The transverse fixing rods 30 have a hollow internal structure and a transverse telescopic rod 32 is slidably installed inside. One end of the transverse telescopic rod 32 extends out of the transverse fixing rod 30 and is connected to a longitudinal fixing rod 36. The longitudinal fixing rod 36 has a hollow internal structure and a longitudinal telescopic rod 37 is slidably installed inside. One end of the longitudinal telescopic rod 37 extends out of the longitudinal fixing rod 36 and is connected to a second sliding frame 21. First electric push cylinders 24 are symmetrically arranged on the bottom ends of both sides of the second sliding frame 21. A first pressure plate 23 is connected to the output end of the first electric push cylinder 24. Multiple pressure detection units 25 are arranged on the contact end surface of the first pressure plate 23. Multiple rollers 22 are arranged on the bottom end face of the middle part of the second sliding frame 21.

[0041] Specifically, the second sliding frame 21 is placed on the end face of the protrusion of the ridge 10. During installation, the first sliding frame 11 is installed first. Then, the distance between the outward extension of the transverse fixing rod 30 and the longitudinal fixing rod 36 is adjusted according to the width and height of the ridge, so that the second sliding frame 21 can be positioned on the end face of the ridge protrusion. Subsequently, the output end of the second sliding frame 21 pushes the first pressure plate 23 to press against the end face of the protrusion. During this process, multiple pressure detection units 25 on the contact end face of the first pressure plate 23 will detect the pressure of the support clamping, thereby determining whether it is fixed in place. The detection method and specific structure of this pressure detection unit 25 are the same as those of the pressure detection unit 25 on the first pressure plate 23, and will not be elaborated further in this scheme. When the equipment needs to be moved, the first electric push cylinder 24 is raised, so that the roller 22 contacts the end face of the protrusion of the ridge 10, allowing the equipment to slide on the ridge.

[0042] Further, see attached document. Figure 2 and attached Figure 3 The transverse telescopic rod 32 and the longitudinal telescopic rod 37 are provided with anti-slip surfaces 33 on one side of their outer circular surfaces. Each anti-slip surface 33 is provided with a threaded hole on one side of the outer circular surface of the transverse fixed rod 30 and the longitudinal fixed rod 36. A fixing screw 31 is threadedly connected in the threaded hole.

[0043] Specifically, after the equipment is fixed in the construction area, the horizontal telescopic rod 32 extends out of the horizontal fixed rod 30. After it reaches the appropriate position, the fixing screw 31 is manually rotated to make one end of the screw contact the anti-slip surface 33, thereby fixing the position of the horizontal telescopic rod 32. At the same time, the longitudinal telescopic rod 37 extends out of the longitudinal fixed rod 36 to the appropriate position, and the fixing screw 31 on the longitudinal fixed rod 36 is manually rotated to fix the length of the longitudinal telescopic rod 37.

[0044] Further, see attached document. Figure 8 A ventilation chamber 48 is provided in the end face of the second sliding frame 21 near the ridge 10. Multiple inclined first air outlets 18 are provided on the end face of the ventilation chamber 48 near the ridge 10. Multiple fans 20 are provided on one side of the ventilation chamber 48 in the middle of the second sliding frame 21. Multiple second air outlets 19 are provided on the outer side of the fans 20 on the end face of the ventilation chamber 48.

[0045] Specifically, while ensuring the stability of the entire mounting frame during construction, multiple fans 20 will be activated, generating airflow. The air will flow from one side of the fan 20 to the second air outlet 19, and then enter the ventilation chamber 48. The air entering the ventilation chamber 48 will be blown upwards along the first air outlet 18 onto the sloping surface of the roof ridge 10, thereby providing ventilation for the personnel working on the sloping surface of the roof ridge and achieving the purpose of cooling.

[0046] Furthermore, see the attached document. Figure 1 Appendix Figure 4 Appendix Figure 5 and attached Figure 7 Multiple exhaust ducts 13 are provided on the upper end face of the first sliding frame 11. Multiple air outlets are provided on the outer circular surface of the exhaust duct 13. The top of the exhaust duct 13 has a conical cover to reduce rainwater entering the duct through the air outlets. The exhaust duct 13 is equipped with a motor and fan blades to generate air flow. A bellows 12 is provided on one side of the exhaust duct 13 on the end face of the supporting horizontal plate 47. The bellows 12 has a hollow structure in the middle and a downward sloping air outlet 15 on one end face. The other side of the bellows 12 is connected to the exhaust duct 13 through a duct 14. Multiple temperature detectors 42 are provided below the bellows 12 on the end face of the supporting horizontal plate 47.

[0047] When the lower ventilation chamber 48 blows air outward, multiple exhaust ducts 13 will operate. At this time, multiple downward-sloping air inlets 15 will draw air inward. The drawn-in air will enter the air duct 14 and then be discharged outward through the exhaust ducts 13. Meanwhile, the bottom ventilation chamber 48 blows air upward. Taking advantage of the characteristic that hot air tends to rise, the exhaust ducts 13 draw in air, which will generate airflow on the sloping surface of the roof ridge, thereby achieving the purpose of cooling. During this process, the temperature detector 42 will detect the temperature on the roof ridge, thereby controlling the air volume to ensure the cooling effect and improve construction efficiency.

[0048] Example 2:

[0049] Based on Example 1, further examples are provided, please refer to the appendix. Figure 6 Appendix Figure 7 Appendix Figure 8 and attached Figure 9 Two rollers 34 are arranged between two longitudinal fixed rods 36. Torsion springs are installed on both sides of the inner end faces of the two rollers 34. A rotating shaft is connected to the middle of the torsion springs, and a shielding cloth 35 is connected to the outside of the rotating shaft. The torsion springs and rotating shaft are conventional existing technologies for automatic material retraction of the rollers 34, and will not be elaborated upon or drawn in this solution. One end of each shielding cloth 35 extends beyond the outer circumference of the roller 34 and is connected to a buckle 43. A first slot 16 is provided on the top end face of the bellows 12 outside the roller 34, and a second slot 17 is provided on the top of the second sliding frame 21.

[0050] Specifically, once the equipment is fixed in place, when it is necessary to cover the top of the construction frame, the operator pulls out the covering cloth from one of the rollers 34, and attaches the buckle 43 at one end of the covering cloth 35 to the outside and connects it to the first slot 16, thereby covering the top of the construction frame. Similarly, if one side of the construction frame needs to be covered, the covering cloth 35 can be pulled out from the other roller, and the buckle 43 at one end can be attached to the second slot 17, thereby covering one side of the end face. It should be noted that the snap-fit ​​structure of the buckle 43 with the first slot 16 and the second slot 17 is conventional prior art, and this application will not elaborate on it further.

[0051] It should be noted that the purpose of the protective tarpaulin is not only to prevent people and objects from falling from heights, but also to provide shade and rain protection, ensuring safety while providing a more comfortable working environment.

[0052] Further, see attached document. Figure 3 The bottom of the first sliding frame 11 is provided with a movable slot 46, and a slider 40 is slidably mounted in the movable slot 46. An anchor point 29 is provided on the end face of the slider 40 facing the work area for fixing safety belts, safety ropes and other devices. During construction, workers can tie a safety rope to their bodies and then connect the other end of the safety rope to the anchor point 29, thereby ensuring the safety of workers during construction.

[0053] Finally, it should be noted that the connection and fixing of each part of the roof construction edge protection device of the present invention can be achieved by conventional mechanical connection structure, and the control system and connection method required between multiple electrical components and driving components can also be achieved by conventional means and can be equipped with corresponding sensors and detectors. As long as it can achieve its beneficial effect or the specific actions in the above work, it can be implemented.
