Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, and in particular to a three-dimensional water tank settlement joint structure. Background Technology
[0002] In the construction of three-dimensional water tank structures, reinforcing the formwork at settlement joints is crucial to ensuring structural stability and waterproofing performance. Existing technologies have the following problems:
[0003] 1) Poor adaptability to deformation: Traditional rigid reinforcement systems (such as large formwork assembly) use fixed supports. After construction, the formwork support system inside the settlement joint cannot be removed, which makes it impossible to install the caulking material inside the settlement joint. It is also difficult to adapt to the later settlement or temperature deformation of the structure, which can easily lead to leakage risk.
[0004] 2) Low construction efficiency: The settlement joint structure needs to be constructed in stages, and the formwork needs to be disassembled and reassembled multiple times, which consumes a lot of manpower and resources. It is especially difficult to operate in narrow spaces, and large slabs need to be used for construction, which leads to a significant extension of the construction period.
[0005] 3) High material costs and waste: Reliance on traditional materials such as wood results in low turnover rate. Complex structures require customized non-standard components, leading to serious waste of material costs.
[0006] 4) High difficulty in quality control: Formwork reinforcement is not easy to operate and can easily cause defects in concrete forming (such as misalignment and uneven surface), affecting the appearance quality and waterproof performance of the structure.
[0007] In summary, existing construction methods for settlement joints cannot simultaneously achieve both functionality and construction efficiency. Therefore, it is necessary to develop a three-dimensional settlement joint construction method for water tanks that combines settlement adaptability, construction efficiency, and economy. This method would have significant engineering value in improving the construction quality and durability of water tank structures. Summary of the Invention
[0008] This utility model provides a three-dimensional water tank settlement joint structure that combines settlement adaptability, construction efficiency, and economy to solve the technical problems existing in the prior art.
[0009] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: a three-dimensional water tank settlement joint structure, wherein the settlement joint is set between the pre-cast wall and the post-cast wall, and a settlement deformation absorption structure and a caulking plate are provided in the settlement joint. The settlement deformation absorption structure includes multiple horizontal connecting rods corresponding one-to-one with the three-section water-stop screw rods. The horizontal connecting rods pass through the settlement joint, and a sleeve is installed on the horizontal connecting rod. The sleeve is coated with grease. The diameter of the sleeve is determined according to the design value of the deformation, the length is the same as the width of the settlement joint, and it is inserted into the caulking plate. The three-section water-stop screw rod is the tie rod of the two side templates of the pre-cast wall. One end of the horizontal connecting rod is threadedly connected to the connecting nut of the three-section water-stop screw rod left in the pre-cast wall, and the other end of the horizontal connecting rod is connected to the water-stop screw rod. The water-stop screw rod and the turnover rod connected to it pull the outer template of the post-cast wall and the caulking plate together.
[0010] Based on the above solution, the present invention has made the following improvements:
[0011] The sleeve is made of PVC.
[0012] The horizontal connecting rod is welded to the water-stop screw.
[0013] The joint sealing board is made of extruded polystyrene board or EPS board.
[0014] The advantages and positive effects of this utility model are as follows: it uses a settlement deformation absorption structure set in the settlement joint to absorb settlement deformation, uses a joint caulking plate to form the inner template of the post-cast wall, and uses water-stop bolts and horizontal connecting rods to form a template tension fixation. There is no need to install and remove the inner template of the post-cast wall and its supporting structure, which reduces the amount of manual operation in narrow spaces. It is not only simple to construct, efficient and low cost, but also solves the problem of templates hindering the installation of joint caulking materials in traditional processes. It can combine settlement adaptability, construction efficiency and economy. Attached Figure Description

[0020] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:
[0021] Please see Figures 1-4 A three-dimensional water tank settlement joint structure is provided, wherein the settlement joint is set between the pre-cast wall 1 and the post-cast wall 13, and a settlement deformation absorption structure and a joint plate 6 are provided in the settlement joint. The settlement deformation absorption structure includes multiple horizontal connecting rods 7 corresponding one-to-one with the three-section water-stop screw rods. The horizontal connecting rods 7 pass through the settlement joint, and a sleeve 4 is installed on the horizontal connecting rod 7. The sleeve 4 is coated with grease. The diameter of the sleeve 4 is determined according to the design value of the deformation, the length is the same as the width of the settlement joint, and it is inserted into the joint plate 6.
[0022] The three-section water-stop screw rod is the tie rod for the two side formworks of the pre-cast wall.
[0023] One end of the horizontal connecting rod 7 is threadedly connected to the connecting nut of the three-section water-stop screw rod placed in the pre-cast wall, and the other end of the horizontal connecting rod is connected to the water-stop screw rod. The water-stop screw rod and the turnover rod connected thereto pull the outer template of the post-cast wall and the caulking plate together.
[0024] The more preferred solution in this embodiment is as follows:
[0025] The sleeve 4 is made of PVC, which has good mechanical properties and is corrosion resistant.
[0026] The horizontal connecting rod 7 is welded to the water-stop screw rod, ensuring high connection reliability.
[0027] The jointing board 6 is made of organic materials such as extruded polystyrene board or EPS board, which has a certain rigidity and is not easily deformed under pressure.
[0028] The construction method for the above-mentioned three-dimensional water tank settlement joint structure adopts the following steps:
[0029] 1) Constructing the pre-cast wall 1: During the construction of the pre-cast wall 1, the formwork on both sides is reinforced with three-section water-stop bolts. After the concrete is poured, the turnover rods are removed, and the connecting nuts are left inside the pre-cast wall 1. This is based on existing technology and will not be described in detail here.
[0030] 2) Arrange settlement deformation absorption structures in the settlement joint, including horizontal connecting rods 7. The number of horizontal connecting rods 7 is the same as the number of three-section water-stop screw rods. They cross the settlement joint and are threaded to the connecting nut on the side near the settlement joint at the end closest to the pre-cast wall 1. Install sleeves 4 on the horizontal connecting rods 7 and apply grease 5 between the sleeves 4 and the horizontal connecting rods 7. The diameter of the sleeves 4 is determined according to the design value of the deformation, and the length of the sleeves is the same as the width of the settlement joint.
[0031] 3) Use caulking plate 6 to fill the settlement joint. The caulking plate is placed vertically and fitted onto the sleeve 4.
[0032] 4) Construct the post-cast wall 13 using the following steps:
[0033] 4.1) Reinforced concrete structure for the construction wall;
[0034] 4.2) Connect a water-stop screw rod 3 to each horizontal connecting rod 6, connect a turnover rod to the end of the water-stop screw rod 3 away from the settlement joint, install the outer template 8 and its fixing structure on the turnover rod, the joint caulking plate also serves as the inner template, and install the end template.
[0035] 4.3) Pouring concrete;
[0036] 4.4) After the concrete strength of the wall reaches 1.2MPa, remove the outer formwork 8 and continuously monitor the settlement and deformation of the wall in accordance with the specifications.
[0037] In step 4.2), the outer template 8 is a fixed template, which has the characteristics of high turnover rate, strong versatility and good molding quality.
[0038] In steps 1) and 4.3), both the first-poured wall 1 and the subsequent-poured wall 13 are poured using a layered, continuous pouring process. The thickness of each layer is controlled within 500mm. Combined with the settlement deformation absorption structure in the settlement joint, this ensures that the concrete is compacted, improves the structure's self-waterproofing performance, and significantly reduces the wall leakage rate.
[0039] In step 4.2), the outer formwork fixing structure includes main and secondary back ribs, wherein the main back ribs are locked with buckles and conical nuts 12. The outer formwork fixing structure can precisely adjust the verticality and flatness of the formwork through the conical nuts, significantly reducing quality defects such as concrete misalignment and honeycomb surface.
[0040] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
