Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a prefabricated pipe support. Background Technology

[0002] Concrete pipe supports are widely used in pipeline construction. Traditional cast-in-place concrete pipe supports have long construction cycles, involve a large amount of on-site wet work, are easily affected by environmental factors, and have poor quality stability. While prefabricated concrete pipe supports have improved construction efficiency to some extent, they still have many problems. Existing prefabricated solutions often use a combination of precast full-height columns and precast beams, resulting in numerous hoisting operations and low efficiency. The beam-column connection is located at the beam end, making dry connections costly, while wet connections are difficult to control in terms of quality and require waiting for the concrete to harden, further reducing construction efficiency. In addition, traditional solutions often use corbels to achieve scaffolding-free and support-free construction, but concrete corbels affect the pipeline layout space, and temporary steel corbels increase construction costs. Therefore, there is an urgent need for a more efficient, economical, and reliable prefabricated concrete pipe support solution. Utility Model Content

[0030] Combined with appendix Figures 1 to 8 As shown, where, Figure 1Shown in the figure is a prefabricated pipe support, including a precast column 1 and an integral beam-column. Among them, the integral beam-column includes a longitudinally arranged connecting column 3 and a transversely arranged cross beam 9 which are integrally formed. The precast column 1 is arranged on a base. Among them, the integral beam-columns are several and longitudinally connected. The shapes of the integral beam-columns are several, such as a square structure 12 and an H-shaped structure 11. Figure 2-8 Among them, the integral beam-column structures are respectively a square structure 10, a portal structure 12, an H-shaped structure 11, a portal structure 12, a square structure 10, a day-shaped structure 13 and an eye-shaped structure 14. Different or the same integral beam-column structures can be selected according to the longitudinal length of the connecting column 3 so as to improve the overall strength.

[0031] Combined with the attached Figure 9 Shown in the figure, this figure is a schematic diagram of the connection section of the connecting column 3 and the precast column 1. In this figure, the connection is combined by means of a grouting sleeve and a non-support connection. It can be seen from the figure that several steel bars 6 with different lengths are arranged in the precast column, corresponding to the connection methods of the grouting sleeve connection and the non-support connection respectively. The steel bars 6 on both sides extend out of the precast column 1. When the upper precast integral beam-column is hoisted to the lower precast column, the steel bars 6 are aligned and inserted deeply into the grouting sleeve 7 embedded in the connecting column 3 to keep the precast column horizontal. The steel bars 6 extend into the grouting sleeve 7, and the subsequent connection is cast by grouting to improve the connection strength; a first connection sleeve 4 is embedded in the middle position of the precast column 1, and a second connection sleeve 5 is embedded at the position corresponding to the connecting column 3. The first connection sleeve 4 and the second connection sleeve 5 are connected by a T-shaped connecting rod 8. In order to facilitate the rotation of the T-shaped connecting rod 8, during construction, the T-shaped connecting rod 8 is placed in the second connection sleeve 5, and then an external thread inner sleeve is put in, the external thread inner sleeve is screwed into the second connection sleeve 5, and then the T-shaped connecting rod 8 is screwed into the first connection sleeve. For convenient operation, a concave groove structure is arranged at the corresponding positions of the precast column 1 and the connecting column 3. Specifically, reference can be made to Figure 10 Shown in the figure; the connection method is not limited to that shown in the figure.

[0032] Combined with Figure 11 Shown in the figure, several connecting nuts are arranged in the conversion box 15. Embedded sleeves are arranged on both the precast column 1 and the connecting column 3. The conversion box 15 is fixedly connected to one of the embedded sleeves on the precast column 1 or the connecting column 3. When the connecting column 1 and the precast column 3 are butted, they are配合 by the embedded sleeve and the connecting nut. By using the conversion box 15, the connection efficiency between the precast column 1 and the connecting column 3 or adjacent connecting columns 3 can be efficiently improved; the opening side of the conversion box faces the outer surface of the precast column, which is convenient for operation. Since the upper and lower surfaces of the conversion box in this embodiment are subjected to large forces, the wall thickness is relatively large, and the wall thickness of the other several surfaces is relatively small, saving materials while ensuring the connection quality. In addition, in order to improve the strength of the conversion box 15, rib plates can be arranged between the connecting nuts. <​Component Design and Fabrication: During the factory prefabrication stage, the prefabricated concrete pipe support components are divided into lower-level prefabricated short columns and upper-level "portal-shaped, H-shaped, or U-shaped" beam-column integral prefabricated components. During prefabrication, the concrete mix ratio, rebar tying, and embedded part positioning are strictly controlled. High-precision molds are used to ensure accurate component dimensions. Simultaneously, standard connecting sleeves or grooves are reserved at the column ends of the integral prefabricated beam-column components to prepare for subsequent installation.

[0034] On-site installation process: During construction, foundation treatment and surveying are carried out first to ensure the accurate installation position of the lower-level precast short columns. The lower-level short columns are then hoisted into place using a specialized positioning device, and temporary fixing and verticality adjustments are made to ensure stability. Subsequently, the upper-level "portal, H-shaped, or U-shaped" precast beam-column components are hoisted onto the lower-level short columns, ensuring precise alignment of the connection points.

[0035] Application of connection technologies: Vertical connections between columns are achieved using mature connection technologies such as support-free connection technology or sleeve grouting. If sleeve grouting technology is used, the sleeve and rebar surfaces must be cleaned before connection to ensure they are free of oil and impurities. After inserting the rebar into the sleeve, high-strength cement-based grout is injected, and pressure grouting ensures a dense filling of the grout, resulting in a firm connection between the upper and lower columns. If support-free connection technology is used, a rapid and stable connection is achieved through specific mechanical connection devices or structural measures, without the need for additional support structures.

[0036] Post-construction treatment: After completing the vertical connection, the gaps at the connection points are filled with high-strength cement-based grout to improve the integrity and sealing of the connection. Simultaneously, the entire prefabricated concrete pipe support system is inspected and accepted to ensure that all indicators meet design and specification requirements.

[0037] Beneficial effects:

[0038] Significantly improved construction efficiency: Traditional prefabricated solutions use precast full-height columns and precast beams, requiring multiple hoisting and splicing operations. This invention, however, uses precast components consisting of lower-level short columns and upper-level beams and columns, reducing the number of hoisting operations. The upper-level integral component can be hoisted in a single operation to complete the installation of multiple beam-column nodes, greatly improving hoisting efficiency and shortening the overall construction cycle compared to traditional methods. This is particularly suitable for large-scale pipeline engineering projects with tight schedules.

[0039] Effective control of construction costs: On the one hand, it avoids the high costs of traditional dry connections; on the other hand, the vertical connection method replaces the wet connection of the post-cast section, eliminating the need to wait for concrete to harden and reducing construction time costs. At the same time, eliminating the corbel design avoids the costs of redesigning and adjusting pipelines that might be caused by the space occupied by concrete corbels between pipeline layers, and also reduces the additional construction costs brought by temporary steel corbels, thus reducing construction costs from multiple aspects.

[0040] Ensuring reliable project quality: The beam-column connections utilize prefabricated "portal, H-shaped, or U-shaped" components, manufactured in a standardized factory environment. Compared to on-site casting or beam-end connections, this method better guarantees the reliability of beam-column connections, which are crucial structural nodes. High-strength cement-based grouting reduces wet work compared to traditional wet connections, minimizing the impact of on-site wet working conditions on construction quality. It also improves the density and strength of the connection, ensuring the stability and durability of the entire pipe support structure.

[0041] Optimizing the construction environment and management: This reduces a significant amount of on-site wet work and complex connection procedures, lowering noise and dust pollution during construction and improving the construction site environment. Simultaneously, the simplified construction process facilitates construction management and quality control, reducing management difficulty and risks, and enhancing construction safety and standardization.
