Description

Technical Field

[0001] The invention relates to the technical field of prefabricated concrete parts, and in particular to a UHPC high-performance concrete prefabricated part for roads and bridges. Background Art

[0002] Prefabricated parts refer to concrete products that are processed and produced in a factory in a standardized and mechanized manner. In contrast, traditional cast-in-place concrete requires on-site mold making, on-site pouring and on-site maintenance. In the construction of buildings such as roads and bridges, a large number of reinforced concrete structures are used to enhance the strength of the buildings. Generally, the formwork is cast-in-place. The prefabricated parts need to be placed in the position where they need to be poured, and then the concrete is poured into the prefabricated parts for maintenance and molding, which makes it easier to build the building into the required shape. The building has better stability, which is convenient for the construction and use of buildings such as roads and bridges. UHPC is a concrete material with extremely high strength, durability and toughness. Compared with traditional concrete, UHPC has significant performance advantages and is suitable for engineering projects that need to withstand extreme loads, harsh environments and long life.

[0003] Currently available prefabricated parts are all separate individuals and are only suitable for being stacked together. It is not possible to fix several prefabricated parts together, which will easily lead to gaps between the prefabricated parts and increase the instability between the prefabricated parts.

[0004] Therefore, we proposed a UHPC high-performance concrete precast component for roads and bridges to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a UHPC high-performance concrete prefabricated part for roads and bridges.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A UHPC high-performance concrete prefabricated component for a road bridge comprises a first prefabricated component, wherein both left and right ends of the first prefabricated component are fixedly connected to a first positioning frame, and both ends of the two first positioning frames that are away from each other are provided with a fixing mechanism, and the fixing mechanism comprises a first U-shaped block, a sliding rod is provided on the first U-shaped block, the sliding rod penetrates the first U-shaped block and is slidably connected thereto, a sliding plug block is fixedly connected to the left end of the sliding rod, the sliding plug block penetrates the first positioning frame and is slidably connected thereto, a spring is sleeved on the sliding rod, one end of the spring is fixedly connected to the sliding plug block, and the other end of the spring is fixedly connected to the corresponding first U-shaped block, an extension plate is fixedly connected to the first U-shaped block, a first threaded rod is provided on the extension plate, the first threaded rod penetrates the extension plate and is threadedly connected thereto, one end of the first threaded rod is fixedly connected to a first torsion column, and the other end of the first threaded rod is fixedly connected to a fixed plug rod, a positioning plug hole is provided on the sliding rod, and a pull ring is fixedly connected to the sliding rod.

[0008] Preferably, the rear end of the first preform is fixedly connected to a second U-shaped block, the second U-shaped block is rotatably connected to a first bevel gear, the second U-shaped block is rotatably connected to a threaded rod, the threaded rod is coaxially fixedly connected to the first bevel gear, and the second U-shaped block is fixedly connected to two positioning rectangular blocks.

[0009] Preferably, an extension block is fixedly connected to the front end of the first prefabricated component, a threaded insertion hole is provided on the extension block, and two positioning rectangular grooves are provided on the extension block.

[0010] Preferably, a second rotating rod is provided on the second U-shaped block, the second rotating rod passes through the second U-shaped block and is rotatably connected thereto, one end of the second rotating rod is fixedly connected to a second bevel gear, and the second bevel gear is meshed with the first bevel gear.

[0011] Preferably, one end of the second rotating rod away from the second bevel gear is fixedly connected to a second torsion column.

[0012] Preferably, a second preform is provided above the first preform, and the left and right ends of the second preform are fixedly connected with second positioning frames, the lower ends of the two second positioning frames are fixedly connected with blocks, the lower ends of the two blocks are highly connected with rectangular plugs, and the two rectangular plugs are provided with fixed rectangular grooves.

[0013] Preferably, both of the two second positioning frames are provided with a fixing mechanism.

[0014] Compared with the existing technology, the advantages of this device are:

[0015] 1. The first threaded rod is driven to rotate by twisting the first twisting column, and the first threaded rod drives the fixed plug rod to move in the direction close to the sliding rod until the fixed plug rod is inserted into the positioning hole on the sliding rod, so that the sliding rod can be stuck, and the sliding plug block is fixed in a state of being pulled out of the first positioning frame, and the two rectangular plug blocks on the second prefabricated part are inserted into the two first positioning frames, and then the fixed plug rod is pulled out of the corresponding positioning holes, and the sliding plug block is inserted into the two fixed rectangular grooves under the elastic force of the spring, so that the second prefabricated part is fixed above the first prefabricated part through the fixing mechanism, and the two rectangular plug blocks on the new second prefabricated part can be inserted into the second positioning frame and fixed by the fixing mechanism, so as to realize the stacking and fixing of the first prefabricated part and several second prefabricated parts.

[0016] 2. By aligning the two positioning rectangular blocks on the first preform and inserting them into the two positioning rectangular grooves on the other first preform, the threaded rod can be aligned with the threaded socket on the other first preform. By twisting the second twisting column, the corresponding second rotating rod is driven to rotate, thereby driving the corresponding second bevel gear to rotate. The second bevel gear drives the first bevel gear to rotate, so that the threaded rod is rotated and screwed into the threaded socket on the first preform, thereby fixing the two first preforms side by side.

[0017] In summary, the present invention can realize fixed connection between multiple prefabricated parts, so that multiple prefabricated parts can be conveniently stacked and fixed, reducing the possibility of gaps when connecting prefabricated parts, and through the setting of the above-mentioned structure, the stability of the connection between prefabricated parts is also higher.
