Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a safe operating platform suitable for skylight construction. Background Technology

[0002] The combination of steel structures and skylights is becoming increasingly common. During construction, safety during skylight installation has become a key concern and a major challenge. Current technology often involves welding protective railings and operating platforms onto the steel structure. However, this method is inconvenient, difficult to install and dismantle, cannot be reused, and wastes labor and materials. Furthermore, welding to the structure can damage steel components and anti-corrosion coatings, compromising structural safety. Dismantling requires grinding and repair, which can cause secondary damage to the structure. Welding and cutting consume electricity, involve frequent hot work, and generate large amounts of welding fumes and dust, which is detrimental to energy conservation, environmental protection, and fire safety. Utility Model Content

[0003] To address the aforementioned problems, embodiments of this utility model propose a safe operating platform suitable for skylight construction.

[0004] This utility model discloses a safe operating platform for skylight construction, comprising: a horizontal beam with limit bolt holes at its end; a vertical column at the other end of the horizontal beam with rope holes spaced apart; a first clamping plate detachably mounted to the end of the horizontal beam via a sleeve, and vertically positioned below the horizontal beam; a second clamping plate fixedly mounted at the bottom center of the horizontal beam, parallel to the first clamping plate, and connected to it by fastening bolts; the end of the horizontal beam is secured to the first clamping plate by limit bolts and / or limit components; a scaffolding system installed above two adjacent horizontal beams near the column; and a steel wire rope connected to the rope holes at the top of two adjacent columns.

[0005] There are at least two rope holes, located in the middle and at the top of the column. At least three fastening bolt holes are opened at the bottom of both the first and second clamping plates. The fastening bolts pass through the fastening bolt holes to connect the first and second clamping plates.

[0006] The beams, columns, and clamps one and two are all made of square steel with a cross-sectional dimension of 40×40mm. The width of the scaffolding is half the length of the beams, the height of the columns is 2m, and the distance between two adjacent columns and two adjacent beams is 2m.

[0007] The limiting bolt holes are three vertical bolt holes spaced apart.

[0008] The limiting bolt passes through one of the vertical bolt holes, the limiting sleeve, and the clamping plate.

[0009] The limiting bolt hole is a long, vertical hole, and a horizontal bolt hole is provided at the end of the crossbeam, which is connected to the vertical hole.

[0010] A limiting bolt is installed vertically in the elongated vertical hole. The limiting bolt is located on the outside of the first clamping plate. The limiting component passes through the horizontal bolt hole and abuts against the limiting bolt.

[0011] The limiting component includes a fixed toothed disc fixed at the outer port of the horizontal bolt hole. Multiple fixed teeth are spaced out along the circumferential direction on the outer side of the fixed toothed disc. Each fixed tooth includes a cylindrical section at the bottom and a conical section at the end. A retaining ring is provided on the cylindrical section. The center of the fixed toothed disc is a bolt through hole.

[0012] The limiting component also includes a horizontally arranged screw that passes through a bolt through hole at the center of the fixed gear plate. The two ends of the screw are threaded sections, and the middle is a smooth section. A baffle is provided on the outside of one of the threaded sections. The end of the screw away from the baffle is inserted into a horizontal bolt hole and abuts against the limiting bolt. A clamping gear plate that cooperates with the fixed clamping teeth is movably arranged on the smooth section of the screw. A wing nut is installed between the clamping gear plate and the baffle.

[0013] The clamping toothed disc has multiple clamping teeth spaced circumferentially on the side facing the fixed toothed disc. The clamping teeth are cylindrical and have retaining rings at their ends. When the clamping toothed disc is inserted into the fixed toothed disc, the retaining rings in the clamping toothed disc engage with the retaining rings in the fixed toothed disc.

[0014] The beneficial effects of this utility model are as follows: the detachable connection between the clamping plate and the crossbeam allows for the construction of skylight steel beams of different sizes, making installation and dismantling simple and convenient, saving both labor and materials; the detachable installation method avoids on-site welding and cutting operations, does not damage the steel structure, and allows for multiple reuses of components, improving utilization; it reduces fire hazards and environmental pollution, contributing to energy conservation and environmental protection; the steel wire rope not only provides safety protection but also serves as a safety harness, achieving multiple uses; the setting of the limiting component allows for fine-tuning of non-standard sized skylight crossbeams, making the installation of the crossbeams more stable.

[0029] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] like Figures 1-12As shown, the safety operating platform for skylight construction of this utility model includes: a horizontal beam 2, a column 1, a first clamping plate 3, a second clamping plate 4, scaffolding 6, and steel wire ropes 13. The horizontal beam 2 is horizontally arranged, and a limit bolt hole 8 is opened at the end of the horizontal beam 2; the column 1 is vertically arranged at the other end of the horizontal beam 2, and rope holes 15 are spaced apart on the column 1; there are at least two rope holes 15, located in the middle and at the top of the column 1, specifically, as shown... Figure 3 As shown, there are three rope holes 15: one at the top of the post 1 and two spaced apart in the middle. Adjacent posts 1 are connected by steel wire ropes 13 passing through the rope holes 15. The steel wire rope 13 at the top of the post 1 and the two rope holes 15 in the middle of the post 1 are used to attach safety belts.

[0031] The clamping plate 3 is detachably installed at the end of the crossbeam 2 via the sleeve 7, and the clamping plate 3 is vertically positioned below the crossbeam 2. Specifically, the top of the clamping plate 3 has a sleeve 7, which is connected to the clamping plate 3 by welding or integral molding. The sleeve 7 has a rectangular through hole in the middle, the size of which is slightly larger than the size of the crossbeam 2, allowing the through hole in the sleeve 7 to pass through the crossbeam 2 and suspend the clamping plate 3 on the crossbeam 2. The position of the sleeve 7 can be adjusted according to the width of the sunroof steel beam 5 to accommodate different sizes of sunroof steel beams 5. After the clamping plate 3 is suspended on the crossbeam 2, the limiting bolt hole 8 at the end of the crossbeam 2 is exposed. A limiting bolt 9 is installed in the limiting bolt hole 8 to limit the clamping plate 3, preventing it from moving back and forth and accommodating the size of the sunroof steel beam 5.

[0032] The second clamping plate 4 is fixedly installed at the bottom center of the crossbeam 2. Specifically, the top of the second clamping plate 4 is welded to the bottom center of the crossbeam 2, or the second clamping plate 4 is integrally formed with the crossbeam 2. The second clamping plate 4 is parallel to the first clamping plate 3, that is, the second clamping plate 4 is also perpendicular to the crossbeam 2.

[0033] The first clamping plate 3 and the second clamping plate 4 are connected by fastening bolts 10. The bottom of both the first clamping plate 3 and the second clamping plate 4 are provided with at least three fastening bolt holes 11, and the fastening bolt holes 11 on the first clamping plate 3 correspond one-to-one with the fastening bolt holes 11 on the second clamping plate 4. The length of the first clamping plate 3 below the sleeve 7 is equal to the length of the second clamping plate 4, so that the first clamping plate 3 and the second clamping plate 4 can be connected by passing the fastening bolts 10 through the fastening bolt holes 11.

[0034] During installation, clamping plate 2 (4) and clamping plate 1 (3) should be placed on the two sides of the sunroof steel beam 5 respectively. Then, clamping plate 1 (3) should be fixed to the crossbeam 2 above the sunroof steel beam 5 using limiting bolts 9. Finally, clamping plates 1 (3) and 2 (4) should be tightened at the bottom using fastening bolts 10. Clamping plates 1 (3), 2 (4), and crossbeam 2 should be securely connected to the sunroof steel beam 5 without welding. Rubber pads 12 should be placed at the four corners where clamping plates 1 (3), 2 (4), and crossbeam 2 contact the sunroof steel beam 5 to prevent direct contact with the beam and damage to the steel beam coating.

[0035] Horizontal beam 2, upright column 1, clamping plate 1 and clamping plate 2 are all made of square steel with a cross-sectional dimension of 40×40mm. The height of upright column 1 is 2m, and the distance between two adjacent upright columns 1 and two adjacent horizontal beams 2 is 2m. Scaffolding 6 is installed above two adjacent horizontal beams 2 near one end of the upright column 1, and the width of scaffolding 6 is half the length of the horizontal beam 2.

[0036] The limit bolt hole 8 has two structures, which correspond to two different embodiments.

[0037] Example 1

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, the limit bolt holes 8 are three vertical bolt holes spaced apart, and the end of the crossbeam 2 is fixed to the card plate 3 by the limit bolt 9.

[0039] Specifically, the limiting bolt 9 passes through one of the vertical bolt holes 8, the limiting sleeve 7, and the clamping plate 3.

[0040] This embodiment mainly focuses on the standard part of the sunroof steel beam, with three vertical bolt holes corresponding to three commonly used standard dimensions.

[0041] Example 2

[0042] like Figure 6 As shown, the limiting bolt hole 8 is a long vertical hole, and a horizontal bolt hole is provided at the end of the crossbeam 2. The horizontal bolt hole is connected to the vertical hole.

[0043] A limiting bolt 9 is installed vertically in a long, narrow hole. The limiting bolt 9 is located on the outside of the clamping plate 3 and is used to initially limit the clamping plate 3. A limiting component 16 passes through a horizontal bolt hole and abuts against the limiting bolt 9. The limiting component 16 is used to further fix the limiting bolt 9, thereby ensuring that the clamping plate 3 can be stably installed on the crossbeam 2. Due to the long, narrow vertical hole, the position of the limiting bolt 9 can be adjusted arbitrarily. Therefore, the structure of this embodiment can be applied to skylight steel beams of any size, expanding the application range.

[0044] like Figures 7-11 As shown, the limiting component 16 includes a fixed gear plate 17, a clamping gear plate 18, and a screw 20. The fixed gear plate 17 is fixed at the outer port of the horizontal bolt hole. On the side of the fixed gear plate 17 facing outward, a plurality of fixed retaining teeth 22 are arranged at intervals along the circumferential direction. The fixed retaining teeth 22 include a cylindrical section at the bottom and a conical section at the end. A retaining ring 21 is provided on the cylindrical section. The center of the fixed gear plate 17 is a bolt through hole.

[0045] The fixed gear plate 17 is connected to the horizontal bolt hole at the end of the crossbeam 2 by welding, so that the bolt through hole in the center of the fixed gear plate 17 is connected to the horizontal bolt hole.

[0046] The screw 20 is horizontally positioned, passing through the bolt through hole at the center of the fixed gear plate 17. The screw 20 is divided into three sections: threaded sections 24 at both ends and a smooth section 25 in the middle. One of the threaded sections 24 is equipped with a baffle 26 on its outside. The end of the screw 20 away from the baffle 26 is inserted into the horizontal bolt hole and abuts against the limiting bolt 9. By rotating the screw 20, the length of the screw 20 inserted into the horizontal bolt hole can be adjusted so that the screw 20 can abut against the side of the limiting screw* located in the vertical hole, thereby fixing the position of the limiting screw 9.

[0047] Alternatively, an arc-shaped limiting plate (not shown) can be installed on the end of the screw 20 away from the baffle 26 to increase the contact area between it and the limiting bolt 9.

[0048] A clamping gear 18 is movably mounted on the smooth section 25 of the screw 20, engaging with the fixed retaining teeth 22. This means the clamping gear 18 can move and rotate back and forth on the smooth section 25. A wing nut 19 is installed between the clamping gear 18 and the baffle 26. When the clamping gear 18 moves on the smooth section 25, the wing nut 19 can move on the threaded section 24 near the baffle 26, and the movement of the wing nut 19 can limit the clamping gear 18.

[0049] Multiple clamping teeth 23 are spaced apart along the circumference on the side of the clamping toothed disc 18 facing the fixed toothed disc 17. The clamping teeth 23 are cylindrical and have retaining rings 21 at their ends. When the clamping toothed disc 18 is inserted into the fixed toothed disc 17, the retaining rings 21 in the clamping toothed disc 18 cooperate with the retaining rings 21 in the fixed toothed disc 17.

[0050] Specifically, by rotating the clamping toothed disc 18, the clamping tooth 23 and the fixed tooth 22 can be misaligned, thereby facilitating the clamping toothed disc 18 to be pressed into the fixed toothed disc 17, that is, the clamping tooth 23 is inserted into the gap between the fixed teeth 22, so that the retaining ring 21 on the clamping tooth 23 passes over the retaining ring 21 on the fixed tooth 22, thereby achieving the purpose of fastening.

[0051] like Figure 12 As shown, the two sides of the retaining ring 21 are beveled, which facilitates the engagement and disengagement of the corresponding two retaining rings 21. The arrangement of the fixed chuck 17, the clamping chuck 18, the retaining rings 21 and the wing nut 19 can limit the position of the limiting bolt 9.

[0052] In practical use, first rotate the screw 20 so that the end away from the baffle 26 is inserted into the horizontal bolt hole and abuts against the side of the limit bolt 9. Then move and rotate the clamping gear 18 so that the clamping tooth 23 and the fixing tooth 22 engage with each other. Finally, tighten the wing nut 19 to further fix the clamping gear 18.

[0053] When in use, this invention can be installed around the entire perimeter of the skylight, forming a closed operating platform and protective system. Figure 1 As shown, this ensures that workers can easily fasten their safety belts in every area of ​​the skylight, achieving both safety protection and ease of operation.
