Description

Technical Field

[0001] This utility model relates to the technical field of temporary sand cylinder supports for bridges, specifically a sand cylinder support for bridge cap beams or tie beams. Background Technology

[0002] Currently, the construction of bridge cap beams or tie beams generally employs the clamp method or the mandrel method. A cap beam refers to a horizontal beam installed on top of the pier piles to support, distribute, and transfer the load of the superstructure. A tie beam is a beam that acts as a tie rod, primarily to connect two piles or piers into a unified load-bearing structure. Longitudinal beams are longitudinal load-bearing beams. Both clamps and mandrels are used to construct an effective platform base on the cap beam or tie beam, with sand cylinder supports installed on top to provide subsequent support. If effective fixing measures are not taken when placing sand cylinders on the clamps or mandrels, and between the sand cylinders and the longitudinal main beams, the support structure is highly susceptible to collapse under horizontal loads, especially during the construction of cap beams for ultra-high-rise bridges. In reality, during construction, sand cylinders have tilted or even fallen due to varying loads, causing personal injury and property damage.

[0003] Most existing technologies use temporary sand cylinder supports, such as the sand-filled bridge support described in CN202321715192.5. Height adjustment and unloading are achieved through the relative movement of two sleeves. However, they lack corresponding support structures on clamps or mandrels. Therefore, we provide a sand cylinder support for bridge cap beams or tie beams to address these issues. Utility Model Content

[0004] The purpose of this utility model is to make up for the shortcomings of the prior art and provide a sand cylinder support for bridge cap beams or tie beams, so as to solve the technical problem that the prior art lacks a corresponding fixing structure on the tie beam or cap beam to achieve temporary sand cylinder fixing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A sand cylinder support for bridge cap beams or tie beams includes:

[0007] The sand cylinder includes an upper barrel and a lower barrel. An upper steel plate is installed on the top of the upper barrel. The upper barrel and the lower barrel are opened towards each other. The upper barrel is inserted downward into the lower barrel.

[0017] In a further technical solution, the lower barrel body is provided with sand discharge holes, and two sets of sand discharge holes are provided symmetrically; a sealing cap is movably installed outside the sand discharge holes;

[0018] Both the upper and lower barrels are filled with sand.

[0019] In a further technical solution, a vertical groove is provided in the lower barrel, and a closed plate is installed on the side of the upper barrel facing away from the top support.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1

[0041] Please see Figure 1 , 3 -5 and 7 provide a technical solution for this utility model: a sand cylinder support for a bridge cap beam or tie beam support, comprising:

[0042] Sand cylinder 1 includes an upper barrel 11 and a lower barrel 12. An upper steel plate 13 is installed on the top of the upper barrel 11. The upper barrel 11 and the lower barrel 12 are provided with openings facing each other. The upper barrel 11 is inserted downward into the lower barrel 12. A lower steel plate 14 is provided on the side of the lower barrel 12 away from the upper steel plate 13. A threaded hole 1 is opened on the lower steel plate 14, and a threaded hole 2 is opened on the upper steel plate 13.

[0043] The top support 2 includes a fixed plate assembly 21. A threaded post 22 is provided on the side of the fixed plate assembly 21 opposite to the threaded hole 2. The threaded post 22 is threadedly connected to the threaded hole 2. An L-shaped quick-tightening wrench bolt 23 is installed on the fixed plate assembly 21.

[0044] The base 3 has a threaded post 31 threadedly connected to a threaded hole 3; the base 3 includes a positioning element 32, which is suitable for mounting the base 3 on a clamp or a mandrel.

[0045] The fixing plate assembly 21 is provided with a slot 24, and a position plate 25 is fixedly installed under the fixing plate assembly 21 below the slot 24. The position plate 25 has a connecting hole, which is connected to an L-shaped quick-tightening wrench bolt 23. The L-shaped quick-tightening wrench bolt 23 is adapted to connect upward to the position plate 25 and extend into the slot 24, and is threadedly connected to the longitudinal beam. The top slope of the fixing plate assembly 21 is the same as the slope of the corresponding longitudinal beam. In this embodiment, the top of the fixing plate assembly is ground to fit the longitudinal beam for installation.

[0046] like Figure 3 and 7 As shown, the positioning component 32 includes a clamp 37 and a stainless steel cable tie; the stainless steel cable tie includes a first cable tie 38 and a second cable tie 39, both of which are hinged to the clamp 37. A constraint sleeve 310 is installed at the end of the first cable tie 38, and multiple sets of constraint bolts 311 are installed on the constraint sleeve 310; when the end of the second cable tie 39 passes through the constraint sleeve 310, the constraint bolts 311 lock and abut against the second cable tie 39. Figure 7 This is a diagram showing the unfolded shape of a stainless steel cable tie. Figure 3 This is a diagram showing the closed connection of the stainless steel cable ties. The lower barrel 12 has two symmetrical sets of sand discharge holes 15. A sealing cap 16 is movably installed outside the sand discharge holes 15; the sealing cap is threaded onto the outside of the sand discharge holes. Both the upper barrel 11 and the lower barrel 12 are filled with sand 4. The core-through rod method support uses a base with fastening stainless steel cable ties to increase the contact area, changing point contact to surface contact. The fastening stainless steel cable ties effectively connect the base to the core-through rod, ensuring the stability of the support. Furthermore, the base can be replaced to meet the requirements of core-through rod supports of different diameters.

[0047] When using this system, firstly, select a top support with the same slope as the cap beam. Then, based on the cap beam support calculations, select a sand cylinder that meets the tonnage requirements. Finally, select a suitable base based on the support type and size. Use the mandrel method to select a base with secure stainless steel cable ties. All three components are connected by threads to form a single unit. Then, install the base on the mandrel and secure it with stainless steel cable ties, attaching the base to the clamps. After the sand cylinders of the entire support are in place, install the longitudinal beams. Place the longitudinal beams inside the top support and use L-shaped quick-tightening wrench bolts to secure the flange plates of the longitudinal beams to the slots, effectively fixing the longitudinal beams to the top support. Finally, install the distribution beams and panels to complete the erection of the entire cap beam or tie beam support.

[0048] Example 2

[0049] like Figure 2 , 6 As shown in Figures 8 and 9, another embodiment of this utility model is described, which is based on Embodiment 1, as follows: Figure 6 As shown, the fixing plate assembly 21 includes a first sub-plate 211, a main plate 212, and a second sub-plate 213. The longitudinal length of the first sub-plate 211 is less than the longitudinal length of the second sub-plate 213. The position plate 25 is fixedly installed at the bottom of the second sub-plate 213. The longitudinal lengths of both the first sub-plate 211 and the second sub-plate 213 are greater than the corresponding length of the main plate 212. In actual installation, it is considered to install sealant or sealant inside for replenishment. The first and second sub-plates can prevent overflow.

[0050] like Figure 8 and 9 As shown, the positioning component 32 includes a fixed part 33 and a movable part 34. The top of the fixed part 33 is provided with a threaded post 31. Positioning screw holes are provided between the movable part 34 and the fixed part 33, and L-shaped bolts 35 are suitable for installation within these holes. The L-shaped bolts 35 are suitable for locking the movable part 34 onto the fixed part 33. A latch 36 is provided at the bottom of the fixed part 33 and the movable part 34. The latch is suitable for engaging with the bends or reinforcements of the clamp. Reinforcing plates or ribs on the flanges or surfaces of the clamp can provide support for the temporary sand cylinder support. The fixed part and the movable part are tightly secured to the flanges of the two semi-circular clamps by long L-shaped bolts, effectively fixing the clamp to the base. The clamp-type base with latches not only reinforces the clamp connection but also ensures the stability of the support by effectively connecting the base and the clamp.

[0051] Example 3

[0052] like Figure 10 and 11 As shown, this is another embodiment of the present invention, such as... Figure 10As shown, a vertical groove 17 is formed inside the lower barrel 12, and a sealing plate 18 is installed on the side of the upper barrel 11 opposite to the top support 2; a limiting block 19 is provided on the outside of the sealing plate 18, and the limiting block 19 is adapted to be installed in the vertical groove 17. The horizontal section of the vertical groove 17 is a dovetail groove; the limiting block 19 is a dovetail tenon. The dovetail groove connection structure ensures that the two sides cannot move left or right, such as... Figure 11 As shown, this ensures that the sealing plate 18 can descend smoothly during sand unloading.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
