Description

Technical Field

[0001] The invention relates to the technical field of beam and slab production prefabrication, and in particular to a cyclically usable supporting device for beam and slab diagonal braces in a prefabrication yard. Background Art

[0002] In modern bridge construction, precast beam and slab technology has been widely used due to its advantages of high efficiency, economy and controllable quality. The production process of precast beam and slab mainly includes multiple steps such as formwork installation, steel bar binding, concrete pouring, formwork removal and maintenance. In these steps, it is crucial to ensure the stability of the beam and slab structure, especially in the maintenance stage after formwork removal. However, in traditional precast yard operations, there are many shortcomings in the design and use of beam and slab diagonal bracing devices.

[0003] Traditionally, in order to prevent the beams and slabs from falling over during the curing period after demolding, square timber is usually used as a temporary support material. Although this method is simple and easy to implement, its adaptability and reuse rate are significantly limited. Due to the differences between different types of beams and slabs and prefabricated pedestals, the required lengths of supporting square timbers are often different. This means that each support needs to be cut according to the actual situation, resulting in a large amount of wood waste. In addition, due to the different sizes, it is difficult to achieve standardization and recycling, which increases construction costs and resource consumption. Summary of the invention

[0004] The purpose of the present invention is to provide a reusable supporting device for prefabricated field beam and slab diagonal braces, which can be assembled on site and used, and the length can be adjusted according to the height during use, thus solving the problems of different lengths and low reuse rate.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0022] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “front”, “back”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Example, see Figure 1-4 A reusable support device for prefabricated field beam slab diagonal bracing includes a support tube 1 and a connecting tube 2. A threaded telescopic shaft 3 arranged along its length direction is arranged outwardly at one end of the support tube 1. A threaded connecting shaft 31 is arranged at one end of the threaded telescopic shaft 3. A threaded connecting hole 11 threadedly connected to the threaded connecting shaft 31 is opened inwardly at one end of the support tube 1, so that the threaded telescopic shaft 3 and the support tube 1 can be detachably connected. A telescopic hole 21 matching with the threaded telescopic shaft 3 is arranged inwardly at one end of the connecting tube 2. The two opposite outer sides of the threaded telescopic shaft 3 are cut to form a limiting end face 32 arranged along its length direction. Two limiting plates arranged along its length direction are welded in the telescopic hole 21 of the connecting tube 2, so that the cross section of the telescopic hole 21 is a circular segment shape matching with the threaded telescopic shaft 3 and the limiting end face 32, so that the threaded telescopic shaft 3 cannot rotate relative to the telescopic hole 21.

[0026] The end of the connecting tube 2 close to the supporting tube 1 is rotatably connected to a threaded connecting sleeve 4 that is threadedly connected to the threaded telescopic shaft 3. The end of the connecting tube 2 close to the supporting tube 1 is provided with six arc-shaped connecting blocks 22 distributed in a circumference. One end of the threaded connecting sleeve 4 is provided with a circle of rotating connecting rings 41 that match the arc-shaped connecting blocks 22. The inner wall of the rotating connecting ring 41 is rotatably connected to the outer side of the arc-shaped connecting block 22. The inner wall of the rotating connecting ring 41 is recessed inward to form a circle of annular connecting grooves 42. The free end of each arc-shaped connecting block 22 is provided with a circle of rotating connecting rings 41 that match the arc-shaped connecting blocks 22. A limiting protrusion 23 is provided which can be inserted into the annular connection slot 42. The inner edge of the rotating connection ring 41 close to one end of the connection pipe 2 is cut to form a circle of annular inlet cut angle 43. The outer edge of the free end of each limiting protrusion 23 is cut to form a tip cut angle 24. The rotating connection ring 41 is aligned with the connection pipe 2, and the arc-shaped connection block 22 is squeezed and deformed inward by knocking. Then, under its elastic action, the limiting protrusion 23 is inserted into the annular connection slot 42, so that the threaded connection sleeve 4 and the connection pipe 2 can be installed and connected. Three rotating sockets 44 distributed in a circle are provided on the outer side of the threaded connection sleeve 4. When the rotation is laborious, the insertion shaft can be inserted into the rotating socket 44 to drive the threaded connection sleeve 4 to rotate, making the rotation more labor-saving.

[0027] The end of the support tube 1 away from the connecting tube 2 is rotatably connected to a first steel plate base 12, the rotation between the first steel plate base 12 and the support tube 1 is damped, and a first rubber pad 13 is provided on the side of the first steel plate base 12 away from the support tube 1. The end of the connecting tube 2 away from the support tube 1 is rotatably connected to a second steel plate base 25, the connection between the second steel plate base 25 and the connecting tube 2 is damped, the first steel plate base 12 and the second steel plate base 25 rotate in the same plane, and a second rubber pad 26 is provided on the side of the second steel plate base 25 away from the connecting tube 2.

[0028] How to use: Reference Figure 5 When in use, first connect the threaded telescopic shaft 3 to the support rod through the threaded connecting shaft 31, then connect the threaded telescopic shaft 3 to the threaded connecting sleeve 4 and insert it into the telescopic hole 21 to form a connection with the connecting pipe 2, and first rotate the threaded connecting sleeve 4 to adjust the length of the threaded telescopic shaft 3 extending into the telescopic hole 21, pre-adjust the length of the supporting device, and then support the second rubber pad 26 on the ground, support the first rubber pad 13 on the outside of the beam and slab, so that the supporting device forms an inclined support, and rotate the threaded connecting sleeve 4 again to make the threaded telescopic shaft 3 slowly extend from the telescopic hole 21, and finally make the two ends of the supporting device tightly against the end surface to provide inclined support for the beam and slab.

[0029] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
