Description

Technical Field

[0001] The utility model relates to the technical field of aqueducts, in particular to a rectangular aqueduct template supporting structure. Background Art

[0002] An aqueduct is an overhead water-transportation structure used to convey water across rivers, roads, mountain streams, and valley mouths. It consists of a channel, supporting structures, foundations, and inlet and outlet structures. The channel primarily serves to convey water. For beam-type or arch-type aqueducts with a framed arch structure, the channel also serves as a longitudinal beam.

[0003] At present, in the traditional construction process, it is usually necessary to divide the aqueduct body into two construction phases, that is, the first phase is to construct the bottom plate to 500mm of the aqueduct body, and set the copper anchor plate body for water stopping, and the second phase is to complete the remaining parts of the aqueduct body. During the construction of the aqueduct, since the aqueduct body is provided with construction joints, such a setting increases the construction cost and also increases the hidden danger of water seepage in the aqueduct.

[0004] Therefore, we proposed a rectangular aqueduct formwork support structure to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide a rectangular aqueduct formwork support structure to solve the problem proposed in the above-mentioned background technology that in the traditional construction process, the aqueduct body usually needs to be constructed in two times, that is, the first construction is to construct the bottom plate to 500mm of the aqueduct body, and set the copper anchor plate body for water stopping, and the second construction is to complete the remaining parts of the aqueduct body. During the construction of the aqueduct, since the construction joints are set on the aqueduct body, such a setting increases the construction cost and also increases the problem of hidden dangers of water seepage in the aqueduct.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rectangular aqueduct formwork support structure, comprising an aqueduct body and a frame portion arranged at the bottom of the aqueduct body, a longitudinal beam being arranged in the middle of the bottom surface of the aqueduct body, an anchor plate assembly being buried at the upper end of the longitudinal beam, an inner diagonal bracing branch being welded to the upper end of the anchor plate assembly, the other end of the inner diagonal bracing branch being fixed to the inner wall of the aqueduct body, and the anchor plate assembly being arranged as a support for the inner diagonal bracing branch.

[0007] Multiple groups of external diagonal bracing branches are fixedly installed at equal intervals on both sides of the outer wall of the aqueduct body. The arrangement of the internal diagonal bracing branches and the external diagonal bracing branches is suitable for improving the stability of the aqueduct body. Steel wire meshes are respectively arranged on both sides of the bottom plate of the aqueduct body.

[0008] The inner diagonal bracing branch pipe anchor plate assembly comprises an anchor plate body and a filler laid on the upper end of the anchor plate body.

[0009] The filler of the internal diagonal bracing branch pipe is mainly composed of high-performance modified polymer repair mortar and neat paste.

[0010] The anchor plate body of the inner diagonal brace branch pipe must be pre-buried according to the layout position of the inner diagonal brace branch pipe inside the aqueduct body, placed on the inner side of the longitudinal beam reinforcement, and welded to the upper and lower main reinforcement of the longitudinal beam.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The operator embeds the anchor plate assembly on the longitudinal beam of the bottom plate of the aqueduct body and welds it to the upper and lower main reinforcements of the longitudinal beam to form the inner diagonal brace support of the wall panel. The inner diagonal brace branch pipe is reliably connected with the anchor plate assembly and the external formwork frame to ensure the stability of the reinforcement of the aqueduct body. At the same time, the operator uses the wire mesh installed on the bottom plate to reasonably control the concrete pouring sequence and time, so as to realize the one-time forming of the longitudinal beam rectangular trough.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-4A rectangular aqueduct formwork support structure includes an aqueduct body 1 and a frame part 3 arranged at the bottom of the aqueduct body 1. A longitudinal beam 2 is arranged in the middle of the bottom surface of the aqueduct body 1. An anchor plate assembly 4 is buried at the upper end of the longitudinal beam 2. An inner diagonal bracing branch pipe 5 is welded to the upper end of the anchor plate assembly 4. The other end of the inner diagonal bracing branch pipe 5 is fixed to the inner wall of the aqueduct body 1. The anchor plate assembly 4 is arranged as a support for the inner diagonal bracing branch pipe 5.

[0020] Multiple groups of external diagonal bracing branches 6 are fixedly installed at linear and equal intervals on both sides of the outer wall of the aqueduct body 1. The arrangement of the internal diagonal bracing branches 5 and the external diagonal bracing branches 6 is suitable for improving the stability of the aqueduct body 1. Steel meshes 7 are respectively arranged on both sides of the bottom plate of the aqueduct body 1.

[0021] The anchor plate assembly 4 includes an anchor plate body 41 and a filler 42 laid on the upper end of the anchor plate body 41 .

[0022] The filler 42 is mainly composed of high-performance modified polymer repair mortar and pure paste.

[0023] The anchor plate body 41 must be pre-buried according to the layout position of the internal diagonal bracing branch pipe 5 inside the aqueduct body 1, placed on the inner side of the longitudinal beam reinforcement, and welded and fixed to the upper and lower main reinforcements of the longitudinal beam. The anchor plate is made of Q235B steel with a length of 500mm, a width of 250mm, and a thickness of 12mm. The anchor reinforcement is made of 700mm long HPB335 hot-rolled steel bar with a diameter of 20mm. The welding rod is E43 type, and the weld is a third-level weld.

[0024] During the construction process of aqueduct, it is usually started with the foundation treatment of the excavation section, followed by the foundation treatment of the filling section, the foundation treatment of the steps, the erection of the scaffolding, the installation of formwork, steel bars, the installation of anchor plates, the reinforcement of diagonal bracing steel pipes, the pouring of concrete, the curing of concrete, the removal of the brackets and the closing of the anchor plates, thus completing the overall construction of the aqueduct.

[0025] After the formwork and reinforcement at the bottom of the aqueduct are installed, the anchor plate is installed. When installing the anchor plate, it is usually placed on the inner side of the longitudinal beam reinforcement and welded to the upper and lower main reinforcement of the longitudinal beam. Then, the arrangement and spacing of the inner diagonal bracing branch pipe 5 are determined according to the actual construction plan. At the same time, the inner diagonal bracing branch pipe 5 is installed on the support frame and the anchor plate at the corresponding positions inside and outside the aqueduct body. The two ends of the inner diagonal bracing branch pipe 5 are fixed by fixing parts respectively. After the multi-longitudinal beam rectangular trough reinforcement and formwork are installed and inspected, the wire mesh 7 is installed on the bottom plate at the junction of casting area 1 and area 2 and fixed firmly, and then concrete pouring can be started. The concrete pouring adopts 2 boom-type concrete pump trucks, longitudinal segmentation, horizontal layering, and symmetrical continuous pouring process. First, the concrete of the bottom plate and the junction of the side wall and the bottom plate is poured from the two side walls ( Figure 4The concrete pouring in this area should be continuous and symmetrical. The height of this area should not exceed the height of the armpit. Vibration should be carried out with an inserted vibrating rod to make the concrete flow to the bottom plate. After the intersection area of ​​the bottom plate and the side wall is filled, the concrete in the middle of the bottom plate should be poured. Figure 4 2 areas in the middle), and promptly level, fill, and vibrate to control the elevation to meet the design requirements, and finally pour the trough body concrete ( Figure 4 When pouring concrete on both sides of the trough body (area 3), synchronous symmetrical pouring is adopted, and the thickness of each layer should not exceed 30cm to prevent the concrete surface on both sides from being too different in height, causing the support frame and diagonal bracing to become unstable or other consequences.

[0026] After the concrete pouring is completed, it should be covered and maintained with materials with good water retention properties as required. After the concrete strength of the multi-longitudinal beam rectangular trough reaches the design requirements, the inner diagonal bracing branch pipe 5 and the outer diagonal bracing branch pipe 6 can be removed.

[0027] When sealing the anchor plate, grooves are cut around the anchor plate. The periphery of the chiseled pit should be vertical, and the contour line should form a convex polygon. The contact surface between the new and old concrete is roughened, and the loose concrete part under the anchor plate is chiseled and cleaned. Pay attention to protecting the main beam steel bars. If the steel bars are exposed and rusted, first remove the rust on the steel bars and apply rust-resistant paint. After the base surface is treated, spray water to saturate it. After cleaning the accumulated water, apply modified polymer cement slurry. Set up a two-way φ4@100 notched steel wire mesh in the middle of the concrete thickness above the anchor plate and fix it securely. Use high-performance modified polymer repair mortar for repairs. Finally, apply a single-component polyurea waterproof coating on the surface for sealing.
