Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering equipment, in particular to a T-beam formwork side template hanger. Background Art

[0002] Bridge construction requires the use of T-shaped beams, also known as T-beams. These are constructed by pouring reinforced concrete within a T-beam formwork. This formwork consists of multiple identical side panels. Because these panels are typically constructed from standard steel, they are significantly longer and heavier than standard panels. Consequently, gantry cranes are frequently required to transport these panels during assembly, dismantling, cleaning, and maintenance.

[0003] Since the T-beam is T-shaped and the side formwork is in the shape of a "7", its center of gravity is located at the top and eccentric to the inside. Using steel wire ropes to directly tie the side formwork for hoisting can easily cause the side formwork to become unstable, resulting in damage to the side formwork during the hoisting process, endangering the safety of construction workers and reducing the hoisting turnover efficiency. Utility Model Content

[0004] In response to the deficiencies in the background technology, the utility model provides a T-beam formwork side formwork hoist. A special side formwork hoist is manufactured by the utility model. The hoist has high strength and a stable center of gravity, which reduces the chance of injury during the lifting process of the side formwork, ensures the safety of construction personnel, and improves the turnover efficiency of the side formwork.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a T-beam formwork side formwork hanger, comprising: a horizontal beam and a vertical beam fixedly connected at the ends and in an L-shape, a horizontal beam with adjustable position connected between the horizontal beams along the length direction of the horizontal beam, a hanging hole plate fixedly connected to the side of the horizontal beam, and a hanging hole plate provided with hanging holes on the hanging hole plate, a plurality of cross bars arranged and connected between the vertical beams along the length direction of the vertical beam, a clamping plate extending inwardly is fixedly connected to the vertical beam, and a clamping groove cooperating with the side formwork is provided on the clamping plate.

[0006] By adopting the above technical solution, two lifting points are set on the L-shaped sling, namely the lifting holes set on the lifting hole plate in the horizontal direction and the crossbar set in the vertical direction. Since the crossbar is movably connected to the horizontal beam and multiple crossbars are provided, the positions of the two lifting points in the horizontal and vertical directions are adjustable. In combination with the different center of gravity positions of side templates of different specifications, the overall center of gravity is more stable during the lifting process, reducing unsafe factors during the lifting process. At the same time, the sling of the utility model has a simple structure, is easy to move, and is safe and firm.

[0007] The utility model is further configured as follows: screw holes are provided on the horizontal beam, and the cross beam is fixedly connected to the horizontal beam by bolts. Fixing the cross beam to the horizontal beam by bolts ensures the rigidity of the sling during the lifting process.

[0008] Preferably, multiple screw holes are arranged along the length of the horizontal beam, and the crossbeam is installed at different screw holes to accommodate the lifting of side formworks of different specifications. The provision of multiple screw holes, combined with removable bolts, facilitates adjustment of the crossbeam position before lifting, thereby changing the lifting point position of the sling to accommodate the lifting of side formworks of different specifications.

[0009] Preferably, the crossbeam is welded from two C-shaped steels with openings facing away from each other. Guard plates are welded to the openings at both ends of the C-shaped steels, each provided with a circular hole that communicates with the screw hole. The crossbeam welded from two C-shaped steels ensures the strength requirements of the sling while reducing its weight, making it easier to move.

[0010] The utility model further features a lifting hole plate welded to the outward side of the horizontal beam, with multiple lifting holes provided along the length of the horizontal beam. Adjusting the horizontal beam position before lifting can change the position of the lifting point along the length of the horizontal beam. Providing multiple lifting holes on the lifting hole plate can change the position of the lifting point along the normal line of the horizontal beam, allowing the lifting point to be moved across the horizontal plane of the sling, thereby accommodating the lifting of side formwork of various specifications.

[0011] The utility model further features a counterweight rod fixedly connected to the end of the vertical beam away from the horizontal beam to reduce the spreader's rotation during lifting. The counterweight rod is fixedly connected to the end of the vertical beam, adding a torque to the spreader in the direction of weight, preventing the spreader from rotating excessively when lifting the side formwork.

[0012] The utility model is further configured such that the vertical beams and the crossbars are both C-shaped steels. The use of C-shaped steels not only ensures the strength requirements of the sling itself but also reduces the weight of the sling, making the sling safe and firm.

[0013] Preferably, the side of the cross bar opposite to the opening is welded and fixed to the vertical beam.

[0014] The utility model is further configured as follows: the angle between the horizontal beam and the vertical beam is a right angle, and the angle deviation is ±5°.

[0015] Preferably, a reinforcement plate is provided at the angle between the horizontal beam and the vertical beam. The installation of the reinforcement plate ensures the structural strength of the connection between the horizontal beam and the vertical beam and improves the safety of the sling.

[0016] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0017] 1. The horizontal beam movably connected to the horizontal beam, the multiple lifting holes set along the length of the horizontal beam on the lifting hole plate, and the multiple cross bars set in the vertical direction make the lifting point setting on the sling more flexible. Combined with the center of gravity position of the side formwork itself, the entire lifting process is more stable, reducing unsafe factors in the lifting process, reducing the chance of injury during the lifting process of the side formwork, and ensuring the safety of construction workers.

[0018] 2. A large amount of C-shaped steel is used as the material of the spreader, combined with the simple structure of the spreader itself, to ensure the strength of the material while being light in weight, easy to move, safe and firm, and also improve the turnover efficiency of the side formwork.

[0022] The following describes the specific embodiments of the present invention in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, not limiting, of the scope of the present invention.

[0023] like Figure 1As shown, a T-beam formwork side formwork hanger includes a horizontal beam 1, a vertical beam 2, a cross beam 11, a hanging hole plate 12, hanging holes 121, multiple cross bars 21, a clamping plate 22, and a clamping slot 23. The horizontal beam 1 and the vertical beam 2 are fixedly connected at one end so that the two are L-shaped. In this embodiment, the fixed connection is specifically achieved by welding. In order to make the lifting point of the sling flexibly adjustable to adapt to the different center of gravity positions of side templates of different specifications, the sling of this embodiment is provided with two lifting point positions: along the horizontal direction of the sling, the crossbeam 11 is movably connected to different positions in the length direction of the horizontal beam 1 with an adjustable position. Specifically, a plurality of screw holes 13 are provided in the length direction of the horizontal beam 1, and the crossbeam 11 is fixedly connected to different screw holes 13 positions on the horizontal beam 1 by bolts 14. At the same time, the side of the crossbeam 11 is fixedly connected to a lifting hole plate 12 with lifting holes 121, that is, the position of the horizontal lifting point (lifting hole 121) of the sling can be changed by adjusting the position of the crossbeam 11 along the length direction of the horizontal beam 1; along the vertical direction of the sling, a plurality of cross bars 21 are arranged between the vertical beams 2, and the arrangement method can be either evenly spaced or non-evenly spaced. During lifting, a connecting rope such as a wire rope is connected between the cross bar 21 and the hook of the crane, and different cross bars 21 are bundled by the connecting rope to change the position of the vertical lifting point of the sling. Finally, an inwardly extending clip plate 22 is provided on the side of the vertical beam 2 close to the side formwork, and a clip groove 23 is provided on the clip plate 22. When the hoist approaches the side formwork and prepares to lift, the clip groove 23 hooks the formwork of the side formwork to lift it.

[0024] It should be noted that, in order to reduce the weight of the sling and make it easier to move, the sling components of this embodiment are mostly made of C-shaped steel: for example, the crossbeam 11 is welded by two C-shaped steels with openings facing each other. In order to fix the ends of the crossbeam 11 to the horizontal beam 1, Figure 2 As shown, guard plates 111 are welded at the openings at both ends of the C-shaped steel. A circular hole communicating with the screw hole 13 is provided on the guard plate 111. Bolts 14 pass through the screw hole 13 and the circular hole and are matched with nuts to fix the crossbeam 11 to the horizontal beam 1. At the same time, the vertical beam 2 and the crossbar 21 are also made of C-shaped steel. The vertical beam 2 includes two C-shaped steels with openings facing each other, and the crossbar 21 includes multiple C-shaped steels with specifications smaller than the vertical beam 2.

[0025] In order to ensure that the connection strength of the sling is sufficient to ensure safety, one side of the vertical beam 2 is welded and fixed to the side opposite to the opening direction of the cross bar 21; in addition, the angle connection between the horizontal beam 1 and the vertical beam 2 is easily damaged by force, so a triangular reinforcement plate 4 is fixed at the angle to reinforce the sling.

[0026] To ensure a rational structure and facilitate lifting, a counterweight rod 3 is fixed to the end of the vertical beam 2, facing away from the horizontal beam 1. This counterweight rod 3 is fixed to the end of the vertical beam, adding a torque to the spreader in the direction of weight, preventing excessive rotation during the installation of the side formwork. The L-shaped shape of the horizontal and vertical beams 1 and 2 is designed to match the side formwork, with an angle of 90° ± 5°.

[0027] In order to ensure the stability of the center of gravity of the side formwork during the lifting process, the position of the lifting point in the horizontal direction must be adjustable along the normal direction of the horizontal beam 1 (the length direction of the beam 11) during the calculation of the center of gravity of the side formwork. The improved structure adopted in this embodiment is to extend the length of the lifting hole plate 12 and set a plurality of lifting holes 121 in the length direction of the lifting hole plate 12 to achieve this (not shown in the drawings); of course, it can also be achieved by setting a slide groove on the beam 11 and the lifting hole plate 12 can be slidably connected to the slide groove.

[0028] To sum up, the working principle and specific use process of the present invention are as follows: according to the center of gravity position of the side formwork to be transported, the two suitable lifting point positions of the sling are calculated, the position of the crossbeam 11 is adjusted first, the suitable lifting hole 121 is selected as the horizontal lifting point, and the suitable crossbar 21 is selected as the vertical lifting point, and the two lifting points are connected and fixed to the hook through the lifting rope; the crane is started to move the sling to a position near the formwork of the side formwork, and the clamping plate 22 of the sling moves toward the formwork of the side formwork, and the formwork is clamped by the clamping plate 22. The side formwork is lifted and moved to the required position. Since the lifting rope on one side of the vertical lifting point is longer, the horizontal beam 1 remains balanced, thereby eliminating the influence of the center of gravity position being upper and eccentric to the inside due to the shape of the side formwork, thereby improving the lifting stability, and then the clamping plate 22 leaves the formwork; the crane then transports the next side formwork through the sling of the present invention. The entire transportation process is convenient and stable, and the operation of lifting or placing the side formwork is simple and efficient.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
