Description

Technical Field

[0001] The utility model relates to an edge protection device for a cantilevered eave of a sloping roof, belonging to the technical field of building construction. Background Art

[0002] In the traditional construction process of building roofs, guardrails are needed to protect the edge of the roof to prevent people from falling and play a role in safety protection. At present, such guardrails are generally made of materials such as steel bars and steel pipes. They have the characteristics of being able to withstand large external impacts, so they have good safety performance.

[0003] In the traditional roofing construction of sloping roofs, edge protection is entirely dependent on external scaffolding. When the roofing construction is not completed, the scaffolding cannot be removed for external wall construction, which has a great impact on the interlacing of processes, and the external scaffolding materials cannot be removed in time, increasing the construction cost. To this end, a utility model patent with a Chinese patent announcement number and authorization number of CN214786201U discloses an edge protection device for a cantilevered eave of a sloping roof, including a cantilevered eave and two U-shaped clamps, both of which are against the side walls and bottom of the cantilevered eaves, and the upper ends of the two U-shaped clamps are welded with vertical uprights, and the upper ends of the two U-shaped clamps are fixed to the vertical uprights through oblique support rods, and the axial side walls of the two vertical uprights are sleeved with two cross fasteners, and the cross fasteners arranged at the upper ends of the two vertical uprights are commonly connected to a horizontal rod, and each of the U-shaped clamps is connected to the cantilevered eaves through two symmetrically arranged fixed structures. When this edge protection device is used, after the construction of the sloping roof structure is completed, it can be directly installed and fixed on the eaves cantilever board, and the external scaffolding can also be removed in time, which can effectively solve the problem of interlacing exterior wall engineering processes.

[0004] However, this edge protection device still has the following problems in actual use: since the horizontal rod and the vertical rod are connected by a cross fastener, it is difficult to adjust the horizontal rod when the protection position needs to be changed according to the height of the staff, which makes the overall edge protection device less flexible to use and should be improved. Utility Model Content

[0005] In order to solve the above problems existing in the prior art, the utility model provides an edge protection device for the cantilevered eaves of a sloping roof.

[0006] The technical solution of the utility model is as follows:

[0010] Wherein, a hand wheel is arranged on the plate wall of one side of the vertical plate away from the screw rod side, and the hand wheel movably passes through the vertical plate and is fixedly connected with the corresponding side end of the screw rod.

[0011] Among them, the U-shaped clamps on both sides are also provided with a slot at the end position away from the horizontal protective rod side, and the slots on both sides are located on the side wall of the corresponding U-shaped clamp close to the screw rod side. A baffle is also arranged between the U-shaped clamps on both sides, and the two side ends of the baffle are both clamped in the corresponding side slots.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example: Please refer to Figures 1 to 3 The present embodiment provides an edge protection device for a cantilevered eave of a sloping roof, comprising a cantilevered eaves body 1, a U-shaped clamp 2 symmetrically installed on the cantilevered eaves body 1, and fixing parts 3 arranged on both sides of the U-shaped clamps 2 for fixing the U-shaped clamps 2 on both sides to the cantilevered eaves column, and vertical upright poles 4 arranged vertically upward are also fixed on both sides of the U-shaped clamps 2. A movable seat 5 is slidably connected to the vertical upright poles 4 on both sides, and a plurality of movable seats 5 are arranged on the same vertical upright pole 4. The movable seats 5 on the vertical upright poles 4 on both sides are arranged one-to-one. The specific number and distribution of the movable seats 5 can be determined according to actual conditions. In the present embodiment, the number of movable seats 5 is 4, and 2 movable seats 5 are arranged on 1 vertical upright pole 4. The movable seats 5 on the same vertical upright pole 4 are arranged in an upper and lower distribution. The movable seats 5 on the same vertical pole 4 are connected to each other by setting a connecting rod 17, and horizontal protection rods 6 are set between the movable seats 5 at corresponding positions on the vertical poles 4 on both sides, and the two ends of the horizontal protection rods 6 are fixedly connected to the corresponding movable seats 5. A driving assembly is also set between the U-shaped clamps 2 on both sides, and the driving assembly is connected to the horizontal protection rod 6 located between the movable seats 5 on both sides at the bottom. The driving assembly is used to drive the horizontal protection rod 6 at this position to slide between the vertical poles 4 on both sides. When the horizontal protection rod 6 at this position slides, it can drive another horizontal protection rod 6 located above it to follow the movement through the connecting rod 17.

[0022] In this embodiment, the driving assembly includes a vertical plate 7 that is symmetrically arranged front and back, and a screw rod 8 is rotatably connected between the vertical plates 7 on both sides. A movable block 9 is threadedly connected to the screw rod 8, and a connecting arm 10 is provided on the movable block 9. One end of the connecting arm 10 is hinged to the movable block 9 by setting a hinge shaft 11, and the other end is fixedly connected to the horizontal protective rod 6 located between the two movable seats 5 on the lowest side.

[0023] To ensure the movement of the movable block 9, a guide rod 12 is provided between the two side vertical plates 7. The guide rod 12 is arranged in the same direction as the screw rod 8, and the guide rod 12 is also arranged parallel to the screw rod 8. The movable block 9 is slidably connected to the guide rod 12 by opening a guide hole 13.

[0024] In order to facilitate the user to rotate the screw rod 8, a hand wheel 14 is provided on the wall of the front vertical plate 7 away from the screw rod 8. The hand wheel 14 movably passes through the vertical plate 7 and is fixedly connected to the corresponding side end of the screw rod 8.

[0025] Through the above-mentioned setting, when it is necessary to adjust the protective position of the horizontal protection rod 6 according to the height of the staff, the staff drives the screw rod 8 to rotate by turning the hand wheel 14, so that the movable block 9 moves on the screw rod 8 according to the rotation direction of the screw rod 8. The movable block 9 is affected by the guide rod 12 and will not rotate with the screw rod 8. Therefore, the movable block 9 can only move along the screw rod 8 to adapt to the rotation of the screw rod 8. After the movable block 9 moves, the horizontal protection rod 6 can be pushed or pulled by the connecting arm 10, so that the horizontal protection rod 6 can slide up and down between the vertical poles 4 on both sides, thereby adjusting the protective position to adapt to the height of different staff. When the connecting arm 10 pushes or pulls the horizontal protection rod 6, the connecting arm 10 can swing appropriately through the setting of the hinge shaft 11 to adapt to the movement of the movable block 9.

[0026] To ensure safety during construction, the ends of the U-shaped clamps 2 on both sides away from the horizontal protection rod 6 are further provided with a slot 15, and the slots 15 on both sides are located on the side wall of the corresponding U-shaped clamps 2 close to the screw rod 8. A baffle 16 is further provided between the U-shaped clamps 2 on both sides, and the ends of the baffle 16 on both sides are both clamped in the corresponding side slots 15, and the bottom surface of the baffle 16 is abutted against the top surface of the cantilevered cornice body 1. The baffle 16 can block fine particles, thereby effectively preventing impurities such as stones from falling between the U-shaped clamps 2 on both sides and injuring people.

[0027] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
