Description

Technical Field

[0001] This invention relates to the field of building decoration and construction technology, and in particular to an electric protective curtain device and construction method for vertical openings near edges. Background Technology

[0002] During building decoration and renovation, the traditional "five-edge" protection method for balcony structures, using steel pipes and skirting boards, is used, with a protection height of only 1.2m. This method is mainly suitable for the protection of edges and openings on standard floors (around 3m). However, current building structures have higher floor heights, and the exterior facades of balconies often have odd or even floor heights, typically 6-7m. This method presents several problems: incomplete sealing of openings at the building edges; insufficient strength of the steel pipes; wall and ceiling work exceeding the edge protection level; workers are involved in working at heights; construction materials are at risk of falling, resulting in significant safety hazards during construction; safety belts are required for edge protection during renovation, and the safety hazards slow down construction efficiency, severely impacting the construction progress, leading to low labor utilization and increased construction costs; slow installation efficiency and low material reuse rates increase installation labor and material costs.

Detailed Implementation

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so that the objectives, technical solutions, and advantages of the present invention will be clearer. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0047] Figure 1-9 The present invention illustrates the structure of an electrically operated protective curtain device for vertical openings at the edge, comprising a track system 1, a protective system 2, a lifting system 3, and a power system 4. The lifting system 3 is installed on the exterior wall of the building and is located at the top of the vertical opening of the structural layer to be decorated (or it can be installed near the top of the vertical opening). The track system 1 is installed on the exterior wall of the building and is located below the lifting system 3. The track system 1 is connected to the protective system 2 and is also connected to the lifting system 3. The lifting system 3 is used to drive the protective system 2 to move along the track system 1, so that the protective system 2 moves to a preset position of the vertical opening. The power system 4 is installed on the working surface floor of the structural layer to be decorated and is connected to the lifting system 3.

[0048] The track system 1, protection system 2, and lifting system 3 all use rigid materials, which effectively improves the integrity of the closure of the vertical openings near the edge and provides a safe environment for high-altitude operations. The power system 4 uses motor braking to adjust the protection height. The height of the protection system 2 is adjusted according to the different vertical opening heights and the height of the construction work surface. By adopting modular assembly processes for different systems, the installation efficiency and material reuse rate are improved, and the input of labor and material costs are reduced.

[0049] The track system 1 includes a track 11, a toothed groove 12, and a connecting component 13. The track 11 is made of galvanized steel plate with a thickness of 3mm. Two tracks 11 are respectively set vertically on both sides of the vertical opening at the edge. The toothed groove 12 is set in the track 11 and is used for the vertical climbing of the connecting component 13. The toothed groove 12 is made of galvanized solid steel with a height of 70mm. The connecting component 13 is used to connect the track system 1 and the protection system 2. The connecting component 13 is also used to connect the track system 1 and the lifting system 3.

[0050] The track 11 includes component one 101 and component two 102. Component one 101 is generally U-shaped and includes a base plate 1011 and side plates 1012. The base plate 1011 is fixed to the outer structural wall by bolts. One end of the two parallel side plates 1012 is perpendicularly welded to the base plate 1011, and the other end is welded to component two 102. One of the side plates 1012 has a toothed groove 12 welded to its inner side, which extends along the length of the side plate 1012. The two components two 102 are symmetrically arranged in the U-shaped opening of component one 101, with a certain distance between them. Component two 102 includes plate one 1021, plate two 1022, plate three 1023, and plate four. 1024, one end of plate 1021 is perpendicularly connected to side plate 1012, and the other end extends toward the other side plate 1012 and is perpendicularly connected to one end of plate 2 1022. The other end of plate 2 1022 extends toward the bottom plate 1011 and is perpendicularly connected to one end of plate 3 1023. The other end of plate 3 1023 extends toward the side plate 1012 and is perpendicularly connected to one end of plate 4 1024. The other end of plate 4 1024 extends toward the plate 1 1021. The length of plate 3 1023 is less than the length of plate 1 1021, and the length of plate 4 1024 is less than the length of plate 2 1022. Plate 1 1021, plate 2 1022, plate 3 1023 and plate 4 1024 together form an opening slot 1.

[0051] The connecting assembly 13 includes a climbing gear 131, a track bearing 132, an anti-tilt bar 133, an anchoring component 134, and a crossbar 135. The climbing gear 131 meshes with the toothed groove 12 and is used to climb on the toothed groove 12. The climbing gear 131 is a solid galvanized gear with a diameter of 150mm. A circular hole is opened on the climbing gear 131, and the climbing gear 131 is coaxial with the circular hole. The climbing gear 131 is connected to the track bearing 132, which includes a bearing (not shown in the figure) and a connecting shaft 1321. The bearing and the connecting shaft 1321 are connected, and the bearing is also connected to the climbing gear 131.

[0052] The connecting shaft 1321 is made of galvanized round steel pipe with a diameter of 16mm. The first end of the connecting shaft 1321 passes through the round hole 1 on the climbing gear 131 and a fixing nut 15 is set at the first end of the connecting shaft 1321. The outer surface of the bearing is connected to the round hole 1. During the up and down movement of the connecting shaft 1321, the bearing drives the climbing gear 13 to rotate, so that the climbing gear 13 moves up and down along the tooth groove 12. The fixing nut 15 is a galvanized hexagonal nut with a diameter of 20mm. The fixing nut 15 is used to prevent the track bearing from disengaging from the climbing gear 13 during the up and down climbing process and during use.

[0053] An anti-tilt rod 133 is provided on each side of the connecting shaft 1321. The anti-tilt rod 133 is used to prevent the climbing gear 131 from disengaging from the tooth groove 12 during the climbing process, causing the device to tip over. The anti-tilt rod 133 is made of plain round steel bar with a diameter of 12mm. The anti-tilt rod 133 includes rod one 1331, rod two 1332, rod three 1333, and rod four 1334. One end of rod one 1331 is perpendicularly welded to the anti-tilt rod 133, and the other end extends towards the side plate 1012 and is perpendicularly welded to one end of rod two 1332. The other end of rod two 1332 extends towards the side plate 1021. The first rod 1331 extends and is perpendicularly welded to one end of the second rod 1333. The third rod 1333 extends into the first opening slot from the gap between the fourth plate 1024 and the first plate 1021. The other end of the third rod 1333 extends towards the second plate 1022 and is perpendicularly welded to one end of the fourth rod 1334. The other end of the fourth rod 1334 extends towards the third plate 1023. The fourth rod 1334 is located between the second plate 1022 and the fourth plate 1024. The first rod 1331, the second rod 1332, the third rod 1333 and the fourth rod 1334 together form an opening slot 2, which moves up and down within the opening slot 1.

[0054] The second end of the connecting shaft 1321 is welded to the anchoring component 134. The first and second ends of the connecting shaft 1321 are opposite to each other. The anchoring component 134 includes a connecting rod 1341 and a lifting ring 1342. The connecting rod 1341 is coaxial with the connecting shaft 1321. The connecting rod 1341 is made of galvanized square steel pipe with a specification of 40mm*40mm*3mm. The first end of the connecting rod 1341 is connected to the second end of the connecting shaft 1321. The second end of the connecting rod 1341 is used for the connection between the track system 1 and the protection system 2. There are two pairs of first and second ends of the connecting rod 1341. The connecting rod 1341 is provided with a lifting ring 1342. The lifting ring 1342 is made of plain round steel bar with a diameter of 12mm. The lifting ring 1342 is used for the connection between the track system 1 and the lifting system 3.

[0055] The connecting rod 1341 is also equipped with a crossbar 135, which includes a first crossbar 1351 and a second crossbar 1352. The second crossbar 1352 is used to insert into the first crossbar 1351 to adjust the width. The first crossbar 1351 is made of galvanized square steel pipe with specifications of 40mm*40mm*3mm. One end of the first crossbar 1351 is perpendicularly connected to the connecting rod 1341 by welding. The second crossbar 1352 is made of galvanized square steel pipe with specifications of 30mm*30mm*3mm. One end of the second crossbar 1352 is inserted into the first crossbar 1351, and the other end of the second crossbar 1352 is perpendicularly connected to another connecting rod 1341. The first crossbar 1351 has slots 16 at equal intervals, and the diameter of the slots 16 is 8mm. The end of the second crossbar 1352 inserted into the first crossbar 1351 has a circular hole 2 that connects to the second crossbar 1352. A connecting component 17 is provided at the circular hole 2. The connecting component 17 is inserted into the slot 16 and connects the first crossbar 1351 and the second crossbar 1352.

[0056] like Figure 4 As shown, the connecting component 17 includes a spring 171, an anchor plate 172, and an anchor rod 173. The spring 171 has a diameter of 3mm, and an anchor plate 172 is connected to each end of the spring 171. The anchor plate 172 is made of galvanized steel plate with a specification of 20mm*20mm*2mm. The spring 171 and the anchor plate 172 are located inside the crossbar 1352. The surface of the anchor plate 172 is in contact with the inner wall of the crossbar 1352. An anchor rod 173 is vertically installed on each anchor plate 172, and the anchor rod 173 extends out of the crossbar 1352 through the second round hole. The anchor rod 173 is made of plain round steel bar. The diameter is smaller than the diameter of slot 16, and the diameter of the second round hole is not greater than the width of anchor plate 172 and not less than the diameter of anchor rod 173. When anchor rod 173 is pressed, spring 171 is deformed by the pressure from anchor rod 173. The end face of anchor rod 173 enters the interior of slot 16 but still exceeds the surface of crossbar 1352, which is conducive to crossbar 1352 moving inside crossbar 1351 and adjusting its width. When anchor rod 173 moves to any slot 16, the pressure of spring 171 is released, and the end face of anchor rod 173 exceeds slot 16, fixing the position of crossbar 1351 and crossbar 1352.

[0057] The track system 1 also includes one or more connecting components 2 14. Connecting components 2 14, in conjunction with connecting components 1 13, connect to the protection system 2, improving the stability of the connection of the protection system 2. Connecting components 2 14 include a climbing gear 131, a track bearing 132, an anti-tilt bar 133, an anchoring component 2 141, and a crossbar 135.

The first end and the second end of the fastener 1411 are opposite to each other. The first connector 1412 and the second connector 1413 are used to connect the track system 1 and the protection system 2. The lifting ring 1342 is only provided on the connecting rod 1341 of the first connecting component 13.

[0058] The protective system 2 includes a vertical keel 21, a horizontal keel 22, and a protective net 25. The vertical keel 21 is made of galvanized square steel pipe with a specification of 50mm*50mm*4mm. Both ends of the vertical keel 21 have 42mm*42mm slots 24 for connecting the track system 1 and the protective system 2. The slot 24 on the first end of the vertical keel 21 is aligned with the connecting rod 1341 and pressed in, then connected by bolt 18 (or connected to the connecting piece 1413 by bolt 1).
