A multi-toothed wall-attachment device with adjustable fulcrum

Abstract

This invention discloses a multi-toothed wall attachment device with adjustable fulcrum, comprising a beam, multi-toothed brackets, and a steel platform. The multi-toothed brackets are composed of several brackets arranged opposite each other, with some brackets located inside the beam and others exposed outside. Through-channels for reinforcing bars are formed between the multi-toothed brackets. One end of the multi-toothed bracket located inside the beam is positioned within the beam via the steel platform, while the other end of the multi-toothed bracket exposed outside the beam extends into an opening inside the wall and rests on the bottom surface of the opening. Vertical reinforcing bars inside the wall pass through the through-channels between the multi-toothed brackets. This solution transforms the bracket components extending into the wall from traditional box-shaped components to a multi-toothed shape, allowing the internal reinforcing bars to pass through the gaps in the toothed brackets. This ensures the continuity of the internal reinforcing bars and avoids the problems of wall openings and bracket components interrupting vertical reinforcing bars, greatly improving the applicability of the attachment equipment.

Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and specifically to a multi-toothed wall attachment device with adjustable fulcrum. Background Technology

[0002] High-rise building construction utilizes various climbing equipment such as tower cranes, climbing formwork platforms, jacking platforms, and attachment frames. These devices are typically attached to walls using two methods: creating openings in the wall or attaching steel supports externally. The wall-opening attachment method offers advantages such as lower additional bending moment on the wall, ease of construction, high safety, and lower cost, and is therefore widely used in various climbing equipment.

[0003] Currently, the brackets for various climbing devices that extend into the wall are based on the absence of reinforcing steel bars inside the opening. This results in the need to cut off a large area of ​​vertical reinforcing steel bars inside the wall, especially the vertical reinforcing steel bars located at the edge of the wall constraint components, which are subjected to greater stress. The vertical reinforcing steel bars that are cut by the opening are difficult to reinforce later, resulting in a loss of the wall's load-bearing capacity and limiting the promotion of wall opening attachment methods.

[0004] Therefore, the existing attachment methods for climbing equipment have the technical problem of limited applicability. It is evident that improving the applicability of attachment devices for climbing equipment is a problem that needs to be solved in this field. Summary of the Invention

[0005] To address the technical problem of limited applicability of existing attachment equipment, the present invention aims to provide a multi-tooth wall attachment device with adjustable fulcrum. This attachment device can avoid the problems of wall openings and corbel components breaking vertical steel bars, greatly improving the applicability of the attachment equipment and effectively overcoming the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides a multi-toothed wall attachment device with adjustable fulcrum, comprising a beam, multi-toothed brackets, and a steel platform; the multi-toothed brackets are composed of several brackets arranged opposite each other, with part of the multi-toothed brackets located inside the beam and part exposed outside the beam; a through channel for reinforcing bars is formed between the multi-toothed brackets, one end of the multi-toothed bracket located inside the beam is set inside the beam through the steel platform, and the other end of the multi-toothed bracket exposed outside the beam extends into an opening inside the wall and rests on the bottom surface of the opening, with the vertical reinforcing bars inside the wall passing through the through channel between the multi-toothed brackets.

[0007] Furthermore, a hemispherical groove is provided at the bottom of one end of the bracket, and a ball joint support is provided in the hemispherical groove. The load of the bracket is transferred to the bottom surface of the wall opening through the ball joint support.

[0008] Furthermore, the ball joint support includes a mechanical casting, two wedge-shaped slots, and bolt fasteners; the mechanical casting is mounted on both sides of the bottom end of each bracket through the wedge-shaped slots and bolt fasteners.

[0009] Furthermore, the mechanical casting is a cast steel mechanical part with a spherical top and a circular or square enlarged head at the bottom. The spherical top is connected to the hemispherical groove on the multi-toothed bracket. When the ball joint support contacts the bottom surface of the wall opening, the mechanical casting can rotate inside the hemispherical groove of the multi-toothed bracket, so that the bottom surface of the ball joint support is tightly fitted with the bottom surface of the opening.

[0010] Furthermore, a pin is inserted between the multi-toothed brackets, and the two ends of the pin are respectively connected to the side wall of the beam. Each bracket of the multi-toothed bracket and the pin form a lever effect.

[0011] Furthermore, the multi-toothed bracket is located between the end of the beam body and the steel platform and several height-adjusting screws; the several height-adjusting screws are connected to each bracket in the multi-toothed bracket, and each bracket can be moved vertically through the height-adjusting screw at its end, forming a lever structure with the pin to adjust the elevation of the bracket.

[0012] Furthermore, the brackets and height adjustment screws are staggered and distributed on the steel platform.

[0013] Furthermore, the beam sidewall is provided with an observation port corresponding to the elevation projection position of the internal height adjustment screw.

[0014] The adjustable fulcrum multi-tooth wall attachment device provided by the present invention transforms the corbel component extending into the wall from a traditional box-shaped component to a multi-tooth shape. The internal steel bars of the wall can pass through the gaps in the toothed corbel, thereby ensuring the continuity of the internal steel bars of the wall. This avoids the problems of opening holes in the wall and the corbel component breaking the vertical steel bars, and greatly improves the applicability of the attachment equipment.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0023] To address the technical problem of limited applicability of existing attachment equipment, this invention provides a multi-toothed wall attachment device with adjustable fulcrum. By transforming the corbel component extending into the wall from a traditional box-shaped component to a multi-toothed shape, the internal steel reinforcement of the wall can pass through the gaps in the toothed corbel, thus ensuring the continuity of the internal steel reinforcement. This avoids the problems of opening holes in the wall and the corbel component interrupting the vertical steel reinforcement, greatly improving the applicability of the attachment equipment.

[0024] See Figures 1-2 The adjustable fulcrum multi-tooth wall attachment device provided by the present invention includes a beam 100, a multi-tooth bracket 200, a pin 400, and a steel platform 500.

[0025] The beam 100 is a non-enclosed rectangular structure with a hollow interior, used to house several multi-toothed brackets 200, pins 400, and steel platforms 500.

[0026] The multi-toothed bracket 200 is composed of several brackets 210, which are arranged relatively evenly inside the beam 100 and partially exposed outside the beam 100.

[0027] A through channel for reinforcing bars is formed between each corbel 210. One end of the multi-toothed corbel 200 exposed outside the beam 100 extends into the opening inside the wall and rests on the bottom surface of the opening. The vertical reinforcing bars 700 inside the wall pass through the gap between the corbels 210, which can prevent the wall from opening and the corbel components from breaking the vertical reinforcing bars.

[0028] The diameter of the through-channel here is larger than that of the steel bar 700, allowing the steel bar 700 to pass through the through-channel formed between each corbel 210.

[0029] Secondly, a pin 400 is passed through the multi-toothed bracket 200, and a pin hole is provided on the side wall of the beam 100. The pin 400 is passed through the pin hole and the multi-toothed bracket 200, and a hole edge reinforcing steel plate 410 is provided around the pin hole. After the pin 400 passes through the pin hole, both ends of the pin 400 are reinforced.

[0030] By setting the pin 400, each of the teeth 210 of the multi-toothed bracket 200 forms a lever effect with the pin 400, which allows the multi-toothed bracket 200 to rotate around the pin 400 at a corresponding angle, making it easy to adjust the setting angle of the multi-toothed bracket 200.

[0031] A ball joint support 300 is provided at the bottom of one end of each bracket 210. The load of the bracket 210 is transferred to the bottom surface of the wall opening through the ball joint support 300. The ball joint support 300 can prevent the bracket from being eccentrically stressed due to uneven opening.

[0032] The number of multi-toothed cow legs 200 is not limited here. In some examples, a set of multi-toothed cow legs 200 can be composed of 2 to 4 cow legs 210. The specific number can be selected according to the actual situation.

[0033] See Figure 3 The bottom ball joint support 300 includes a mechanical casting 310, two wedge-shaped slots 320 and a bolt fastener 330.

[0034] The mechanical casting 310 is a cast steel mechanical part with a spherical top and a circular or square enlarged head at the bottom. A hemispherical groove is provided on each bracket 210 to fit the top of the mechanical casting 310. The spherical top of the mechanical casting 310 is fitted inside the hemispherical groove.

[0035] Two wedge-shaped grooves 320 are provided in the mechanical casting 310, and they are fixed to the bracket 210 by bolt fasteners 330. When the ball joint support 300 contacts the bottom surface of the wall opening, the mechanical casting 310 can rotate inside the hemispherical groove of the bracket 210, so that the bottom surface of the ball joint support 300 can fit tightly with the bottom surface of the opening, avoiding unevenness of the bottom surface of the opening that causes the bracket 210 to be subjected to eccentric force.

[0036] The end of the multi-toothed bracket 200 located inside the beam 100 is connected to the steel platform 500 and is set inside the beam 100 through the steel platform 500.

[0037] A height adjustment screw 600 is provided between each bracket 210 and the steel platform 500. Each bracket 210 can be moved vertically through the height adjustment screw 600 at its end, so that the bottom of the ball joint support 300 at its top and bottom is at the same level as the bottom surface of the opening. This method ensures that the multiple attachment points of the climbing equipment can be in close contact with the wall, and also ensures that each bracket at each attachment point is subjected to uniform force.

[0038] Here, each bracket 210 and the height adjustment screw 600 are arranged in a staggered manner on the steel platform 500. On the one hand, this makes the force distribution on the steel platform 500 more uniform, and enables a more stable connection between the bracket 210 and the height adjustment screw 600 and the steel platform 500. On the other hand, the staggered arrangement provides enough space for manual adjustment of the height adjustment screw 600.

[0039] Meanwhile, at the elevation projection position of the height adjustment screw 600, an observation port 110 is provided on the side wall of the corresponding beam 100, so that a person can insert his hand or workpiece into the beam 100 through the observation port 110 to adjust the height adjustment screw 600; at the same time, the adjustment status of the height adjustment screw 600 inside the beam 100 can also be observed through this observation port 110.

[0040] Meanwhile, this solution is not limited to using the height adjustment screw 600 for adjustment; other height adjustment components can also be used to adjust the height of the multi-tooth bracket. The specific structure to be selected can be determined according to the actual situation.

[0041] The following example illustrates the working process of this solution; it should be noted that the following content is only a specific application example of this solution and does not constitute a limitation on this solution.

[0042] When reserving openings in the wall, the vertical reinforcing bars located inside the openings do not need to be cut off. See [reference needed]. Figure 4 First, after the multi-toothed corbel 200 is inserted into the wall opening, the vertical steel bar 700 inside the wall passes through the gap of the multi-toothed corbel 200. The corbel 200 is then placed on the bottom surface of the opening through the spherical support 300. The spherical support 300 can release the bending moment to avoid the eccentric bending moment of the corbel 210 caused by the unevenness of the opening.

[0043] Each bracket 210 of the multi-tooth bracket 200 forms a lever effect with the pin 400. Adjusting the height adjustment screw 600 at the end of the bracket 210 pushes the end of the bracket 210 to move vertically. By adjusting the bottom elevation of the top of the bracket 210 through the lever principle, it ensures that each bracket 210 is in close contact with the bottom surface of the opening, so that each bracket 210 is subjected to force at the same time, and the load is transferred to the wall.

[0044] The multi-toothed wall attachment device with adjustable fulcrum constructed by the above scheme has the following advantages over the prior art.

[0045] First, compared to traditional box-shaped or other shaped components, the multi-toothed brackets in this solution allow the vertical steel bars inside the wall to pass through the gaps between the multi-toothed brackets. After the brackets are transferred, the openings are filled with concrete, achieving the goal of attaching the wall without damaging its load-bearing capacity.

[0046] Secondly, climbing equipment often has multiple attachment points, each of which must be in close contact with the wall. However, the location and shape of the wall openings can vary during construction. To ensure that the actual stress on the structure matches the calculation model and to avoid significant safety risks, it is necessary to ensure that each attachment point is in contact with the bottom surface of the opening. To address this, this solution utilizes a multi-toothed bracket system that leverages the combined action of a pin and a height-adjusting screw. By adjusting the height of the screw, it is possible to ensure that multiple attachment points are in contact with the bottom surface of the opening, while simultaneously ensuring that each bracket at each attachment point experiences uniform stress.

[0047] Meanwhile, when the bottom surface of the wall opening is not horizontal, each bracket will be subjected to eccentric force. Since the load of the climbing equipment can often reach hundreds of tons, it will cause huge torque to the bracket. To address this, this solution sets a ball joint support at the bottom of the bracket. When the bottom surface of the opening is not horizontal, the ball joint can be rotated to ensure that the bracket support point is in close contact with the bottom surface of the opening, which can improve the safety level of the bracket structure.

[0048] In summary, this solution effectively addresses the damage to vertical reinforcing bars caused by wall-mounted attachment methods for climbing equipment during high-rise building construction, expands the application scope of wall-mounted attachment methods, and avoids the more dangerous and less economical external steel support scheme. This reduces costs and increases efficiency for high-rise building construction projects and greatly improves the applicability of attachment equipment.
