Description

Technical Field

[0001] This application relates to the field of water conservancy engineering construction technology, and in particular to a support structure for a through rod. Background Technology

[0002] In water conservancy engineering construction, the temporary support system for cap beams, tie beams, and short-span superstructures is crucial for construction safety and efficiency. Traditional methods often employ a combination of through-bars and channel steel supports, along with hydraulic jacks for load adjustment.

[0003] However, in practical applications, this method has the following problems: Insufficient stability: Ordinary through-bar supports rely on a single point of load-bearing and lack horizontal constraints, making them prone to instability due to eccentric loads or vibrations. Hydraulic system defects: Jacks are costly and complex to maintain, and oil leaks or pipe bursts can cause instantaneous collapse, posing significant safety hazards. Low construction efficiency: Channel steel supports are cumbersome to install, difficult to adapt to different hole diameters, have low reuse rates, and affect project progress. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this application provides a support structure for a through-bar, which enhances anti-overturning capacity based on a triangular force-bearing structure, uses a support instead of channel steel to simplify installation, and introduces sand box unloading technology to avoid hydraulic system risks.

[0005] The first aspect of this application provides a support structure for a through rod, comprising: a support, a through rod, a tie rod, a pad, and a sand box. A bracket is provided on one side of the support, and a reserved hole is provided on the support. The through rod passes through the reserved hole and forms an isosceles triangular force-bearing structure with the tie rod installed in the reserved hole. The end of the tie rod is fixed with a nut based on the pad. A sand box is placed on the support, forming a support system with the upper supporting beam and longitudinal beam.

[0006] The sand box is filled with dry medium sand, and a sand discharge hole is opened at the bottom of the sand box.

[0007] The reserved holes are set according to the diameter of the mandrel and the tie rod, and the hole diameter is 2-3mm larger than the diameter of the mandrel and the tie rod.

[0008] The technical solution provided in this application may include the following beneficial effects:

[0009] This application provides a support structure for a through-bar bearing. The triangular force-bearing structure formed by the through-bar and double tie rods effectively enhances anti-overturning capacity. The bearing features an integral contact surface and lower corbel support to ensure stable force distribution. Pre-drilled holes enable rapid alignment and installation, and the structure is reusable. The sand box controls sand flow to achieve smooth load unloading. Compared to hydraulic jacks, it offers advantages such as low cost, maintenance-free operation, and no leakage risk, making it particularly suitable for short-term load-bearing requirements in hydraulic engineering. This solution addresses the problems of poor stability, low construction efficiency, and significant safety hazards associated with traditional support systems, and is applicable to the through-bar bearing method for short-span structures such as cap beams and tie beams.

[0022] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0023] The figure shows a stable support structure for a support 1 used for a through-bar 2. This structure is used in hydraulic engineering construction where the through-bar 2 is required as a load-bearing support system for components such as cap beams, tie beams, and short-span superstructures. The support structure includes: support 1, through-bar 2, two tie rods 3, pad 4, and sand box 5. The through-bar 2 and two threaded steel tie rods 3 are inserted into pre-drilled holes in the pier / cap beam, with a certain height difference (usually 5-10cm) between the center of the steel bar and the centers of the tie rods 3 on both sides. The centers of the tie rods 3 on both sides maintain the same elevation (lower than the solid steel bar). The through-bar 2 and tie rods 3 are configured as a stable isosceles triangular load-bearing structure, ensuring that the load transfer of the superstructure is borne by the solid steel bar, while the isosceles triangular load-bearing structure of the two threaded steel tie rods 3, together with the support 1, forms a horizontal load-bearing structure.

[0024] The support 1 is manufactured according to the dimensions in the attached drawing. It is formed by welding a t=16mm steel plate, and the contact surface with the concrete is a single steel plate. The lower part is equipped with a bracket 6 structure to ensure stress stability. Precise holes are drilled at the corresponding locations of the solid steel bar and the precision-rolled threaded steel tie rod 3, and the hole diameter can be expanded outward by 2-3mm. The quick-wear support 1 has the characteristics of simple structure, low material consumption, reusability, and stable stress structure.

[0025] A sand box 5 is placed on support 1, and together with the upper supporting beam 7 and longitudinal beam 8, a complete support system can be formed. The sand box 5 is welded from steel plates and filled with ordinary sand. The sand box 5 achieves smooth unloading of load by controlling the flow of sand. Compared with hydraulic jacks, it has the advantages of low cost, maintenance-free operation, and no risk of leakage, and is especially suitable for short-term load-bearing needs of water conservancy projects.

[0026] The specific implementation steps are as follows:

[0027] First, pre-drill holes of matching diameter during the construction of the piers or cap beams. During installation, insert the mandrel 2 horizontally into the pre-drilled holes, and simultaneously insert two precision-rolled threaded steel tie rods 3 symmetrically 5-10cm below the mandrel, forming a stable isosceles triangular force system. Secure the extended ends of the tie rods 3 with washers 4 and nuts.

[0028] When positioning support 1, ensure that its pre-drilled holes are precisely aligned with the steel bar and tie rod 3. The hole diameter should be 2-3mm larger than the diameter of the rod to facilitate installation. Keep the contact surface between support 1 and the concrete flat to ensure even load distribution.

[0029] The upper part of the support system is sequentially equipped with sand box 5, distribution beam 7, and longitudinal beam 8. Sand box 5 is filled with dry medium sand, and the unloading process is controlled through the sand discharge port at the bottom. During construction, the stress state of the support system can be monitored by tracking the settlement of sand box 5. After the concrete structure reaches the design strength, the sand discharge port of sand box 5 is slowly opened to achieve smooth unloading.

[0030] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
