Description

Technical Field

[0001] This utility model relates to the field of exterior wall construction technology, specifically to a suspended basket suspension device for cantilevered eaves. Background Technology

[0002] With the continuous development of society and the construction industry, the requirements for the design level of the construction industry are also getting higher and higher, and the architectural style of extra-wide eaves is favored by owners.

[0003] For the construction of the cantilevered roof facade, where the facade is 4.5 meters above the cantilevered eaves, using conventional scaffolding would disrupt outdoor work, and the large size and high rental costs of external scaffolding would result in wasted time and money.

[0004] In some implementations, a roof cantilever mechanism is often used to suspend a suspended platform for construction. The cantilever mechanism is usually erected using the lever principle. It is constructed by welding square tubes of different specifications and reinforcing ribs, and is supplemented by steel wire ropes, diagonal braces, counterweights, etc. Its front arm extends a certain distance to the outside of the structure, and the rear arm is fixed to the suspension mechanism. The front support of the suspension mechanism is supported on the outward cantilever structure plate, which can easily cause cracks, leaks and other quality hazards to the outward cantilever structure. The counterweight on the rear support will also increase the building load, causing damage to the building structure and potential risks.

[0005] Therefore, conventional lever-type suspended platform installation involves numerous counterweights and connecting components, and the construction is complicated, resulting in many potential safety hazards. Especially in the construction of inter-story staggered cantilever structures, ideal installation conditions are not available, making reliable installation difficult.

[0006] Therefore, it is necessary to study a suspension device for cantilevered eaves hanging baskets. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a suspension device for cantilevered eaves suspended baskets, which can effectively solve the problems of conventional lever-type suspended basket installation structures having many counterweights and connecting parts, complicated construction, many safety hazards, and high installation conditions.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A suspension device for a suspended basket on a cantilevered roof includes a support frame, a crossbeam, a hanger, a lifting wire rope, and a safety wire rope;

[0010] The support frame is installed in two sets at intervals on the left and right sides of the floor slab;

[0011] The crossbeam is supported on two sets of support frames on both sides.

[0012] The hanger is suspended in the middle of the crossbeam, and two sets of rope pulleys are installed on the hanger at intervals.

[0013] The lifting wire rope and the safety wire rope are respectively wound around two sets of rope pulleys and used to pass downward through the hoisting holes on the floor slab and be fixedly connected to the suspended platform.

[0014] Furthermore, the support frame includes a base frame, uprights, and diagonal braces. The base frame is horizontally arranged front and back, the uprights are vertically fixed in the middle of the base frame, and diagonal braces are fixedly connected to both ends of the base frame and the uprights to form a triangular support structure.

[0015] Furthermore, a bracket is fixedly connected to the top of the upright, the bracket having an open U-shaped structure, and the side of the crossbeam is mounted and fixed in the bracket with fasteners.

[0016] Furthermore, the crossbeam is provided with a number of positioning holes at horizontal intervals, and the bracket and hanger are provided with mounting holes corresponding to the positioning holes. The bracket and hanger are fixedly connected to the crossbeam by fasteners passing through the corresponding positioning holes and mounting holes.

[0017] Furthermore, the upright is a telescopic pole, including an inner pole and an outer pole movably sleeved outside the inner pole. Both the inner pole and the outer pole are provided with a number of limiting holes at intervals. The inner pole and the outer pole are fixedly connected by limiting members passing through the corresponding limiting holes.

[0018] Furthermore, the hanger includes a side plate and a connecting plate;

[0019] The side plates are symmetrically arranged in two sets at intervals, and a connecting plate is fixedly connected between the two side plates to form a U-shaped slot with an opening at the bottom of the hanger. The hanger is then mounted on the crossbeam through the U-shaped slot, and the two side plates are fixedly connected to the crossbeam by fasteners.

[0020] Furthermore, the connecting plate is a U-shaped plate with an opening at the bottom, and the two flanges of the connecting plate are fixedly connected to the two side plates respectively. The fastener passes through the two flanges of the U-shaped plate and the two side plates and is fixedly connected to the crossbeam.

[0021] Furthermore, a wheel axle is fixedly inserted between the two side plates, and two sets of wheel axles are arranged at intervals on the left and right and distributed below the crossbeam. The rope wheel is rotatably mounted on the wheel axle.

[0022] Furthermore, the lower ends of the lifting wire rope and the safety wire rope are bundled together and fitted with a protective soft sleeve, which is inserted into the hoisting hole.

[0023] The beneficial effects of the above technical solution are:

[0024] This utility model involves erecting two support frames on a floor slab, then fixing a crossbeam to the support frames. A hanger is fixedly suspended in the middle of the crossbeam, and two rope pulleys are rotatably mounted on the hanger, each equipped with a lifting wire rope and a safety wire rope. The lifting and safety wire ropes are wound around the two sets of rope pulleys and used to pass downward through the floor slab and be fixedly connected to the suspended platform. Compared with the traditional lever-counterweight suspended platform structure, this design eliminates the counterweight part of the conventional suspended platform suspension mechanism, making the suspension mechanism lighter, significantly reducing construction load and construction costs, reducing the load and wear on the floor slab, and improving construction safety. Moreover, it does not rely on traditional scaffolding or large-volume counterweight structures, and can flexibly adapt to the complex eaves shape of staggered cantilevered buildings between floors, possessing a wide range of structural adaptability, and is especially suitable for the construction of facades of high-rise irregular buildings.

[0025] In addition, the dual-rope design of the lifting wire rope and the safety wire rope in this utility model can ensure the safety of the suspended platform during operation. The use of rope pulleys to connect with the hanging frame can effectively reduce the wear and tear of the wire rope and improve safety. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0031] This embodiment aims to provide a suspended platform for cantilevered eaves, which is mainly used for the construction of the exterior facade of cantilevered eaves. It addresses the problems of conventional lever-type suspended platform installation structures, such as numerous counterweights and connecting parts, complicated construction, many safety hazards, and high installation requirements.

[0032] A cantilevered eaves hanging basket suspension device, such as Figure 1This includes a support frame 1, a crossbeam 2, a hanger 3, a lifting wire rope 4, and a safety wire rope 5. The support frame 1 is fixedly installed in two sets at intervals on the left and right sides of the floor slab 6, such as... Figure 2 The support frame 1 is a tripod, comprising a base frame 101, uprights 102, and diagonal braces 103. All components, including the base frame 101, uprights 102, and diagonal braces 103, are made of square steel tubing. The base frame 101 is horizontally fixed to the floor slab 6, and the uprights 102 are welded vertically to the middle of the base frame 101. Diagonal braces 103 are welded and fixedly connected to both ends of the base frame 101 and the uprights 102 to form a triangular support structure.

[0033] Furthermore, the upright 102 is a telescopic pole, including an inner pole 1021 and an outer pole 1022 movably sleeved outside the inner pole 1021. Both the inner pole 1021 and the outer pole 1022 have a 14mm diameter limiting hole 1023 every 150mm on their sides. The inner pole 1021 and the outer pole 1022 are fixedly connected by a limiting member 1024 passing through the corresponding limiting hole 1023. The limiting member 1024 is a high-strength bolt assembly, allowing the device to be height-adjusted. A bracket 9 is welded and fixedly connected to the top of the inner pole 1021, such as... Figure 2 The bracket 9 has an upward-opening U-shaped structure and is used to support both sides of the crossbeam 2.

[0034] The crossbeam 2 is supported on two sets of support frames 1 on both sides, and the hanger 3 is suspended in the middle of the crossbeam 2. Specifically, the side of the crossbeam 2 is supported and fixed in the bracket 9 by fasteners 10. A 14mm positioning hole 201 is provided every 150mm on the side of the crossbeam 2. The bracket 9 and the hanger 3 are provided with 14mm mounting holes 301 corresponding to the positioning holes 201. The bracket 9 and the hanger 3 are fixedly connected to the crossbeam 2 by fasteners 10 passing through the corresponding positioning holes 201 and mounting holes 301. The fasteners 10 are also high-strength bolt kits, which allows the bracket 9 and the hanger 3 to be adjusted to the left and right along the crossbeam 2.

[0035] like Figure 3 The hanger 3 includes a side plate 302 and a connecting plate 303. Two sets of side plates 302 are symmetrically arranged at intervals in front and behind. The connecting plate 303 is fixedly connected between the two side plates 302, so that the hanger 3 forms a U-shaped slot with an opening at the bottom and is mounted on the crossbeam 2 through the U-shaped slot. The two side plates 302 and the crossbeam 2 are fixedly connected by fasteners 10.

[0036] Furthermore, such as Figure 3 The connecting plate 303 is a U-shaped plate with an opening at the bottom. The flanges on both sides of the connecting plate 303 are welded and fixedly connected to the two side plates 302 respectively. The fastener 10 passes through the two flanges of the U-shaped plate and the two side plates 303 and is fixedly connected to the crossbeam 2 as a whole.

[0037] A wheel axle 11 is fixedly inserted between the two side plates 302. The wheel axle 11 is a pin. Two sets of wheel axles 11 are arranged at intervals on the left and right and distributed below the crossbeam 2. Two sets of rope wheels 7 are arranged and rotatably mounted on the two sets of wheel axles 11 respectively.

[0038] The lifting wire rope 4 and the safety wire rope 5 are respectively wound around two sets of rope pulleys 7 and fixed by four rope clamps 8. The lifting wire rope 4 and the safety wire rope 5 are connected to the hanger 3 through the rope pulleys 7, which can reduce the friction loss between the wire rope and the hanger 3.

[0039] Both the lifting wire rope 4 and the safety wire rope 5 are threaded downwards through the floor slab 6 and fixedly connected to the suspended platform. The floor slab 6 has hoisting holes for the lifting wire rope 4 and safety wire rope 5 to pass through. The lower ends of the lifting wire rope 4 and safety wire rope 5 are bundled together and fitted with a protective soft sleeve 12. The protective soft sleeve 12 passes through the hoisting holes in the floor slab 6 to prevent frictional wear between the wire ropes and the floor slab 6. In this embodiment, the hoist is located below the floor slab 6, between the floor slab 6 and the suspended platform, and is used solely to retract the lifting wire rope 4 to lift the suspended platform. This is not within the scope of protection of this application, and all aspects utilize existing technology, which will not be elaborated upon here.

[0040] In this embodiment, a set of lifting wire ropes 4 and a set of safety wire ropes 5 are installed on a set of hangers 3. The lifting wire ropes 4 and the safety wire ropes 5 converge and pass through the floor slab 6 through the same lifting hole. In actual use, two sets of this device need to be installed adjacent to each other to form two lifting points for the same suspended platform, ensuring the stability of the platform. Each lifting point is connected to a set of lifting wire ropes 4 and a set of safety wire ropes 5 to ensure safety. Two corresponding lifting holes are provided on the floor slab 6, allowing the converged wire ropes from the two sets of this device to pass through the floor slab 6.
