DETAILED DESCRIPTION

[0024] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0025] Example 1

[0026] like Figure 1-Figure 3 As shown, the present invention proposes a prefabricated beam bottom support and adjustment structure, including: a beam-making pedestal 1, a support assembly 2 and a reinforcement assembly 3; the beam-making pedestal 1 is installed with a fine-rolled threaded steel bar 101; the support assembly 2 is installed on both sides of the beam-making pedestal 1; the support assembly 2 includes a side panel seat 201, the side panel seat 201 is installed with a stiffening rib 202, the stiffening rib 202 is installed with a steel plate 203, the steel plate 203 is installed with a nut 204 for connecting the fine-rolled threaded steel bar 101; and the reinforcement assembly 3 is installed below the beam-making pedestal 1. The support component 2 is connected to the precision-rolled threaded steel bar 101 by using the matching nut 204, and the stiffening rib 202 cooperates to support and adjust it to the beam-making pedestal 1. The reinforcement component 3 increases the use of the beam-making pedestal 1, and the matching nut 204 of the precision-rolled threaded steel bar 101 is used to accurately adjust the horizontal and vertical slopes. The matching nut 204 of the precision-rolled threaded steel bar 101 has the advantages of not deforming under pressure, combining well with the poured concrete, ensuring the appearance quality of the wedge block at the bottom of the beam, and a smooth transition between the wedge block and the standard section of the precast box beam. During the construction process, the movable wedge block adjustment of the beam-making pedestal 1 can facilitate the reduction of the number of beam-making pedestals 1, reduce construction costs, save labor, improve the accuracy of the wedge block, and improve construction efficiency. At the same time, it also reduces the temporary land area of ​​the precast beam yard construction, which is conducive to practicing green transportation and promoting green highway construction.

[0027] To further illustrate, the reinforcement assembly 3 includes a base 301 mounted below the beam-forming pedestal 1. The base 301 is provided with through-holes for the stiffening ribs 202 to pass through. The base 301 is mounted with a triangular bracket 302, which is equipped with a mounting block 303, which is mounted with a rotating member. The beam-forming pedestal 1 is pre-embedded at the construction site, and the base 301 is connected below the beam-forming pedestal 1 to increase its support. Furthermore, the triangular bracket 302, rotating member, and telescopic column 309 facilitate the coordinated support and adjustment of the beam-forming pedestal 1, thereby enhancing the effectiveness of the precast beam bottom support and adjustment structure.

[0028] To further illustrate, the rotating member includes a housing 304 mounted on the mounting block 303. The interior of the housing 304 is hollow, connected to and mounted with a shaft 305. The housing 304 has openings at both ends that communicate with the exterior, allowing the shaft 305 to pass through. Limit rods 306 are mounted on both ends of the housing 304. A rotating sleeve 307 is mounted around the periphery of the limiting rods 306, and a telescopic plate 308 is mounted on the rotating sleeve 307. The telescopic end of the telescopic plate 308 is mounted on the base 301 to adjust the height of the tripod support 302. The rotating sleeve 307 rotates around the periphery of the limiting rods 306. During this rotation, the telescopic plate 308 telescopes and adjusts, allowing the tripod support 302 to cooperate with the beam-making pedestal 1 during construction.

[0029] Example 2

[0030] like Figure 1 and Figure 2 As shown, the present invention proposes a prefabricated beam bottom support adjustment structure. Based on the above embodiment, this embodiment also records in detail the specific components such as the beam base 1 and the steel plate 203, as well as the matching method.

[0031] Further explanation is that the steel plate 203 and the beam-making pedestal 1 are detachably connected. The beam-making pedestal 1 is connected by rotating the fine-rolled threaded steel bar 101 and the sleeve nut 204, so that the sleeve nut 204 is connected to the steel plate 203, thereby connecting the steel plate 203 and the beam-making pedestal 1. The fine-rolled threaded steel bar 101 and the sleeve nut 204 are rotated and disassembled, so that the steel plate 203 and the beam-making pedestal 1 are disassembled, making it easy to adjust the position of the precast beam according to the construction site.

[0032] Further explanation: the base 301 is detachably connected to the beam-making pedestal 1 and the steel plate 203. During the construction of the precast beam-making pedestal 1, the stiffening ribs 202 are passed through the through holes, and the base 301 is relatively connected to the construction site. The base 301 drives the triangular bracket 302 and the rotating member to strengthen the support of the precast beam-making pedestal 1 and improve the use of the precast beam bottom support adjustment structure.

[0033] To further illustrate, the reinforcement assembly 3 also includes a telescopic column 309 mounted below the triangular support 302. The telescopic column 309 is mounted below the base 301 and is used to support the triangular support 302. During the synchronous adjustment of the triangular support 302 and the beam-forming pedestal 1, the telescopic column 309 is simultaneously adjusted and retracted, facilitating the connection between the top of the triangular support 302 and the beam-forming pedestal 1, and facilitating the coordinated use of the components of the support and adjustment structure.

[0034] The working principle of the present invention is as follows: when the beam-making pedestal 1 is in use, the beam-making pedestal 1 is installed through the fine-rolled threaded steel 101 and the matching nut 204, so that the beam-making pedestal 1 and the steel plate 203 are connected, and the steel plate 203 supports the beam-making pedestal 1. According to the use requirements of the construction site, the height of the fine-rolled threaded steel 101 and the matching nut 204 are adjusted by rotation. The beam-making pedestal 1 is embedded in the construction site for use, and then the prefabricated beam is embedded in use. According to the support requirements, the base 301 is embedded in the construction site. The bottom end of the stiffening rib 202 passes through the through hole and is connected to the construction ground. The stiffening rib 202 cooperates with the steel plate 203 to support the beam-making pedestal 1. The base 301 is connected to the triangular bracket 302 through the telescopic column 309. The upper part of the triangular bracket 302 and the beam-making pedestal are connected. The beam pedestal 1 is connected below. When the beam pedestal 1 is adjusted to use an angle or height, the telescopic column 309 is subjected to the upward moving force of the triangular bracket 302, so that it is telescopic and extended upward. The triangular bracket 302 synchronously supports the beam pedestal 1. The two sides of the triangular bracket 302 drive the mounting blocks 303, and the mounting blocks 303 drive the sleeve 304. The sleeve 304 drives the internal shaft 305, and the shaft 305 drives the limiting rods 306 at both ends. The periphery of the limiting rod 306 and the rotating sleeve 307 are installed, and the rotating sleeve 307 and the telescopic plate 308 are installed. During the adjustment process of the triangular bracket 302, the rotating sleeve 307 rotates, and the telescopic plate 308 is telescopically supported according to the adjustment range of the beam pedestal 1, so that it can support and adjust the beam pedestal 1.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
