Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall installation, and particularly to an integral hoisting device for curtain wall units. Background Art

[0002] In modern architecture, curtain walls, especially glass curtain walls, have become an indispensable and important part of public buildings, especially super high-rise buildings, and have become an important carrier for displaying the building facade form and visual effects. Compared with traditional solid brick walls, glass curtain walls have the advantages of light self-weight, good permeability and daylighting, etc., and can provide excellent indoor views. The development of industrial production has made the application of unitized curtain walls more and more extensive. The curtain wall unit plates are pre-assembled and fabricated in the factory, and only need to be delivered to the site according to the on-site construction plan for hoisting. The installation is achieved by engaging a hanging device connected to the column of the curtain wall unit plate with a channel embedment. How to achieve efficient, safe and economical hoisting of on-site curtain wall unit plates has become an important link in the installation construction.

[0003] The existing solutions are mainly divided into two categories: (1) Hoisting by means of hanging codes on the columns of curtain wall unit plates; (2) Opening hoisting holes on the frames of curtain wall unit plates for installing lifting tools. Such solutions have the following defects:

[0004] Directly using the hanging codes on the columns of curtain wall unit plates for hoisting, the lifting tools are likely to damage the hanging codes, and the lifting ropes are also likely to scratch the unit plates; during the hoisting process, the attitude and center of gravity position of the curtain wall unit plate will change at any time. When using the hanging codes for hoisting, there is an overlapping part between the lifting ropes and the curtain wall unit plate on the facade. During the hoisting process, the operations of avoiding and yielding positions are cumbersome, and there is a hidden danger of the curtain wall unit plate tipping over and falling; opening hoisting holes on the frames of curtain wall unit plates will damage the unit plate structure, and the problems of the disassembly and assembly efficiency of the lifting tools and the operation convenience are prominent. Summary of the Invention

[0005] The purpose of the present invention is: aiming at the deficiencies in the above background art, to provide an improved curtain wall unit hoisting solution.

[0006] To achieve the above purpose, the present invention provides an integral hoisting device for curtain wall units, including a hoisting tool base, a sling assembly and a limiting assembly. The sling assembly and the limiting assembly are both connected to the hoisting tool base. The hoisting tool base is installed on the structure of the curtain wall unit. The sling assembly is used to connect with the hook of the hoisting equipment, and the limiting assembly is used to insert into the structure hole of the curtain wall unit to form a limit, so that the hoisting tool base is stably connected to the curtain wall unit.

[0007] Further, the sling base is installed in a C-shaped groove formed between two cantilever plates on the upper part of the crossbeam male material of the curtain wall unit. Plugging parts corresponding to the slots of the C-shaped groove are arranged on both sides of the sling base, and the plugging parts are inserted into the slots.

[0008] Further, a base cavity is formed in the sling base, and the base cavity is used for installing the limiting component and the sling ring component.

[0009] Further, the limiting component includes a limiting block, a spring and a lever. The limiting block can slide in the base cavity. The spring is connected to the limiting block and the base cavity so that the limiting block is subjected to an elastic force. The lever is connected to the limiting block and is used to control the displacement of the limiting block.

[0010] Further, rollers are also arranged at the bottom of the limiting block.

[0011] Further, a strip-shaped notch for the disassembly, assembly and movement of the lever is formed in the sling base and is distributed along the width direction. The strip-shaped notch communicates with the base cavity so that the lever can drive the limiting block to move along the width direction.

[0012] Further, the upper surface of the limiting block is set as a continuous stepped structure with four levels of height fluctuations, which are in turn a first platform, a first trapezoidal concave platform, a platform with a single-slope surface and a second platform from the head to the tail;

[0013] A threaded hole is formed in the first platform, and an external thread corresponding to the threaded hole is formed at the bottom of the lever so that the lever is fixedly connected to the limiting block;

[0014] Both the first trapezoidal concave platform and the platform with a single-slope surface are matched with the sling ring component.

[0015] Further, the sling ring component includes a sling ring rod, a sling ring located at the top end of the sling ring rod, and a hanging seat located at the bottom end of the sling ring rod. A sling ring mounting hole for the hanging seat to insert is formed in the sling base. The sling ring mounting hole is distributed along the length direction and communicates with the base cavity. The hanging seat is used to cooperate with the sling base and the limiting component.

[0016] Further, a second trapezoidal concave platform is formed on the upper surface of the hanging seat, and a convex platform with a double-slope surface is formed on the lower surface of the hanging seat.

[0017] Further, a local convex platform corresponding to the second trapezoidal concave platform is formed at the top of the base cavity. The local convex platform is arranged along the width direction so as to limit the hanging seat after the hanging seat rotates to the width direction.

[0018] The above solution of the present invention has the following beneficial effects:

[0019] The integral hoisting device for curtain wall units provided by the present invention fully utilizes the upper crossbeam common material of the curtain wall unit to design the hoisting device, without the need for additional processing and damage to the existing curtain wall unit; the drainage holes and other holes on the crossbeam common material and the telescopic design of the limit block are used to realize the limit of the hoisting device and the crossbeam common material in the length direction. Coupled with the circumferential limit of the hoist base and the crossbeam common material, the reliable connection between the hoisting device and the crossbeam common material, that is, with the curtain wall unit, is realized, and it is convenient for the quick disassembly and assembly of the hoisting device and the curtain wall unit; for the two states of the limit block not popped out and popped out, the non-locking and locking states of the sling assembly are constructed to correspond to the two states of the curtain wall unit not allowed to be hoisted and allowed to be hoisted, ensuring the safety of the hoisting process and effectively preventing dangerous situations of human misoperation;

[0020] When hoisting with the hoisting device provided by the present invention, a safety rope can be set on the hanging code of the curtain wall unit, effectively avoiding the potential hazards of the curtain wall unit plate tipping over and falling during the hoisting process. The lifting point is set at the top of the curtain wall unit plate. During the hoisting process, there is no need for the hoisting rope to avoid positions or give way to other components, etc., and the hoisting rope will not scratch or damage the unit plate.

[0021] Other beneficial effects of the present invention will be described in detail in the subsequent specific implementation part. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0031] As Figure 1 shown, an embodiment of the present invention provides an integral hoisting device for a curtain wall unit, including a hoisting base 100, a sling assembly 200, and a limiting assembly 300. Among them, the sling assembly 200 and the limiting assembly 300 are connected to the hoisting base 100 as a whole. The sling assembly 200 is used to connect with the hook of the hoisting equipment. The hoisting base 100 is fixed on the corresponding structure of the curtain wall unit 400. By relying on the limiting assembly 300 to limit the degrees of freedom of the hoisting base 100, the entire hoisting device is stably connected to the curtain wall unit 400, improving the hoisting reliability of the curtain wall unit 400.

[0032] Meanwhile, as Figure 2 shown, in this embodiment, the hoisting device is installed at the position of the C-shaped groove 401 formed between two cantilever plates on the upper part of the crossbeam male material of the curtain wall unit 400. The overall structure of the sling base 100 is square and is located inside the C-shaped groove 401. Therefore, the degrees of freedom of the sling base 100 in multiple directions can be restricted by the C-shaped groove 401.

[0033] Meanwhile, a rubber strip installation boss is provided at the notch position of the C-shaped groove 401, so a slot 402 distributed along the length direction (longitudinal direction) of the C-shaped groove 401 is formed. Plug-in parts corresponding to the slot 402 are provided on both sides of the sling base 100. The plug-in parts are inserted into the slot 402 to further restrict the degrees of freedom of the sling base 100, so that the sling base 100 can only slide along the length direction of the C-shaped groove 401. When installing, the sling base 100 slides into the C-shaped groove 401 from the end. The degrees of freedom are finally further restricted by the limiting component 300.

[0034] Meanwhile, as Figure 3 shown, in this embodiment, the limiting component 300 includes a limiting block 301, a spring 302, a lever 303 and a roller 304. Among them, the overall shape of the limiting block 301 is strip-shaped. A base cavity 101 is provided inside the sling base 100, and the limiting block 301 can slide along the width direction (transverse direction) inside the base cavity 101. The roller 304 is installed at the bottom of the limiting block 301 and is used for the smooth sliding of the limiting block 301 inside the base cavity 101. A spring 302 is installed at the tail end of the limiting block 301, and the other end of the spring 302 is in contact with the base cavity 101. The spring 302 is continuously compressed so that the limiting block 301 is subjected to an elastic reaction force.

[0035] Among them, the head of the limiting block 301 has a tongue-shaped structure, the width of which is smaller than the overall width of the limiting block 301 and is consistent with the width of the drainage hole 403 on the upper part of the crossbeam male material of the curtain wall unit, so as to insert into the drainage hole 403 to form stable limitation, and at the same time prevent the limiting block 301 from completely moving out of the base cavity 101. The upper surface of the limiting block 301 is set as a continuous stepped structure with four levels of height fluctuations, which are the first platform 305, the first trapezoidal concave platform 306, the single-slope surface platform 307 and the second platform 308 in sequence from the head to the tail. A threaded hole 309 is opened on the first platform 305, and an external thread corresponding to the threaded hole 309 is formed at the bottom of the lever 303. Therefore, the bottom of the lever 303 can be connected and fixed to the threaded hole 309, so that the lever 303 is fixed to the limiting block 301.

[0036] To cooperate with the installation of the limit component 300 and the spreader base 100, in this embodiment, a strip-shaped notch 102 for the disassembly, assembly, and movement of the lever 303 is provided on the upper surface of the middle part of the base cavity 101, which is distributed along the width direction, and a limit installation hole 103 is provided on the side surface. During installation, the limit block 301, the roller 304, and the spring 302 are first assembled into an integral body, and then the integral body is inserted into the base cavity 101 through the limit installation hole 103. When the threaded hole 309 on the upper part of the limit block 301 is aligned with the strip-shaped notch 102 of the base cavity 101, the lever 303 is inserted into the strip-shaped notch 102, the bottom of the lever 303 is screwed into the threaded hole 309 of the limit block 301, and the spring 302 is fixed to the inner side wall of the base cavity 101. Relying on the strip-shaped notch 102 distributed along the width direction, the lever 303 can move along the width direction to adjust the position of the limit block 301.

[0037] In this embodiment, the sling assembly 200 includes a sling rod 201, a sling 202 located at the top end of the sling rod 201, and a hanging seat 203 located at the bottom end of the sling rod 201. Among them, the hanging seat 203 is in an overall shape of a ram's horn, the main body connected to the sling rod 201 is a rectangular block, and angled parts that are obliquely cut upward are provided at both ends of the rectangular block. Therefore, the upper surface of the hanging seat 203 is an overall second trapezoidal concave platform 204, and the lower surface is a convex platform 205 with double-sided slope surfaces.

[0038] In this embodiment, a sling installation hole 105 along the length direction is provided at the middle position of the upper surface of the base cavity 101. This hole is rectangular, and the length and width are slightly larger than the length and width of the largest circumscribed rectangle of the hanging seat 203 to facilitate the smooth insertion of the hanging seat 203. The double-sided slope surface convex platform 205 has the same slope as the first trapezoidal concave platform 306 of the limit block 301 and the single-sided slope surface platform 307, so that the hanging seat 203 and the limit block 301 can be smoothly in shape and position fit. At the same time, a local convex platform 106 that cooperates with the second trapezoidal concave platform 204 on the upper surface of the hanging seat 203 is provided on the inner side of the middle part of the top plate of the base cavity 101. During installation, the length direction of the hanging seat 203 is the same as the length direction of the sling installation hole 105. First, the hanging seat 203 is inserted into the base cavity 101. After the hanging seat 203 is completely inserted into the base cavity 101, the hanging seat 203 is rotated 90 degrees. At this time, only the sling rod 201 is located in the sling installation hole 105, so it will not prevent the rotation of the hanging seat 203. At this time, the second trapezoidal concave platform 204 on the upper surface of the hanging seat 203 and the local convex platform 106 of the base cavity 101 can be completely engaged to form a stable and reliable connection. When the second trapezoidal concave platform 204 and the local convex platform 106 are completely engaged, the double-sided slope surface convex platform 205 is no longer located in the first trapezoidal concave platform 306 of the limit block 301, the position of the hanging seat 203 rises, and the double-sided slope surface convex platform 205 is located on the single-sided slope surface platform 307 at this time and the inclined surfaces are fitted. Therefore, the limit block 301 has a spatial structure for front and rear movement.

[0039] When the hoisting device provided in this embodiment is used, before the curtain wall unit panel is hoisted, the hoist base 100, the limit assembly 300 and the hoist ring assembly 200 are pre-assembled as a whole, and inserted from the end of the cross beam material on the upper part of the curtain wall unit 400. At this time, the lever 303 should be pushed to the middle of the hoist base 100 to fully retract the limit block 301 into the base cavity 101 and compress the spring 302. When the limit installation hole 103 on the side of the hoist base 100 is fully inserted into the C-shaped groove 401, the lever 303 can be released, and the head of the limit block 301 is limited by the side wall of the C-shaped groove 401. The hoisting device moves along the length direction of the cross beam material. When it reaches the position of the drainage hole 403 opened on the side wall of the C-shaped groove 401 of the cross beam material, the limit block 301 will automatically pop out under the spring tension, realizing the limit of the hoisting device and the cross beam material in the length direction. When the stop block 301 does not pop out, that is, the spring 302 is in a fully compressed state, the boss 205 with double-sided slopes on the lower surface of the hanging seat 203 of the lifting ring assembly 200 sinks into the first trapezoidal recess 306 of the stop block 301. When the stop block 301 automatically pops out under the tension of the spring 302, under the action of the extrusion force, the hanging seat 203 will rise to the platform 307 with single-sided slopes on the stop block 301 through the cooperation of the inclined surface of the first trapezoidal recess 306, and at this time, the second trapezoidal recess 204 on the upper surface of the hanging seat 203 is fully engaged with the local boss 106 of the base cavity 101.

[0040] It should be noted that the two states of the limit block 301 not popping out and popping out actually just correspond to the two states of the curtain wall unit 400 not allowing lifting and allowing lifting. When lifting is not allowed, the lifting device is still moving in the crossbeam material and has not reached the predetermined position, and the lifting ring assembly 200 is also sunk into the base cavity 101 without being locked; when lifting is allowed, the limit block 301 pops out to limit the lifting device and the crossbeam material in the length direction, and the limit of the lifting device and the crossbeam material in the circumferential direction is added to achieve a reliable connection between the lifting device and the crossbeam material, that is, the curtain wall unit. In addition, the lower surface of the mounting seat 203 fits with the single-sided slope platform 307 of the limit block 301, and the upper surface of the mounting seat 203 is also completely engaged with the local boss 106 of the base cavity 101, and the lifting ring is in a stable locked state, meeting the lifting requirements.

[0041] After the curtain wall unit 400 is hoisted, the lever 303 is moved to retract the limit block 301 into the base inner cavity 101, so that the limit of the hoisting device and the crossbeam material in the length direction can be released, and the hoisting device can be removed by pulling it out from the end of the crossbeam material.

[0042] It should be noted that both ends of the upper crossbeam of each curtain wall unit 400 are provided with hoisting devices to ensure balanced force and more stable hoisting.

[0043] This embodiment fully utilizes the upper crossbeam common material of the curtain wall unit 400 to design the hoisting device, without the need for additional processing and damage to the existing curtain wall unit 400; the telescopic design of the drainage hole 403 and the limit block 301 on the crossbeam common material is used to realize the lengthwise limit between the hoisting device and the crossbeam common material. Coupled with the circumferential limit between the sling base 100 and the crossbeam common material, the reliable connection between the hoisting device and the crossbeam common material, that is, with the curtain wall unit 400, is achieved, and it is convenient for the quick disassembly and assembly of the hoisting device and the curtain wall unit 400; for the two states where the limit block 301 is not ejected and ejected, the non-locking and locking states of the sling assembly 200 are constructed to correspond to the two states where the curtain wall unit 400 is not allowed to be hoisted and allowed to be hoisted, ensuring the safety of the hoisting process and effectively preventing dangerous situations of human misoperation.

[0044] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
