Description

Technical Field

[0001] The invention relates to the field of aqueduct inner molds, and in particular to a cast-in-place movable aqueduct inner mold support system. Background Art

[0002] Aqueducts are structures constructed with overhead channels to transport water across rivers, mountain streams, roads, and valley mouths. In addition to transporting canal water for domestic and industrial use, agricultural irrigation, and inter-basin water transfer, they also serve as flood control and diversion. Aqueduct construction requires the use of formwork to shape the aqueduct. Traditional aqueduct internal formwork support systems require the formwork and support trusses to be disassembled after pouring, moved to the next location, and then reassembled, resulting in low construction efficiency and high costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a cast-in-place movable aqueduct inner formwork support system, which does not require repeated disassembly of the formwork and formwork trusses during operation, and is convenient for moving the formwork, effectively improving construction efficiency and saving construction costs.

[0004] In order to solve the above technical problems, the present invention provides a cast-in-place movable aqueduct inner formwork support system, including a formwork, a formwork truss and a support truss; the formwork truss can roll along the support truss; the formwork is formed by hinged side formworks and a bottom formwork on both sides; a first hydraulic cylinder is installed at the bottom of the formwork truss, and the bottom of the first hydraulic cylinder is fixedly connected to the bottom formwork; the two ends of the support screw are respectively hinged to the side formworks and the two sides of the formwork truss.

[0005] Furthermore, the supporting truss includes two parallel back-to-back double-channel steels; the formwork truss includes a crossbeam and a column; the supporting screw is installed on the side of the column; the first hydraulic cylinder is installed at the bottom of the column; rolling mechanisms are installed at both ends of the lower end face of the crossbeam; the rolling mechanism includes an open housing fixed to the lower end face of the crossbeam; a fixed shaft is installed in the open housing; a first roller is rotatably installed on the fixed shaft; the upper part of the back-to-back double-channel steel is inserted into the open housing; the first roller can roll along the upper surface of the back-to-back double-channel steel.

[0006] Furthermore, the span of the support truss is at least the casting length of three bins; the support truss also includes a support beam and a support column fixed to the support beam; the back-to-back double channel steel is installed on the support column; a second hydraulic cylinder is installed at the lower end of the support beam; the span of the second hydraulic cylinder is the casting length of one bin, and is located on one side of the support truss; the bottom of the second hydraulic cylinder is fixedly installed on the base.

[0007] Furthermore, brackets are installed on both sides of the opening of the open cover body; second rollers are rotatably installed on the brackets; and the vertical distance between the first roller and the second roller is greater than the thickness of the upper part of the back-to-back double channel steel.

[0008] Furthermore, a counterweight is installed at one end of the support beam close to the second hydraulic cylinder.

[0013] Furthermore, a kit is installed on the column, and a detachable support rod is detachably installed between the kits.

[0014] The present invention has the following beneficial effects:

[0015] When the formwork needs to be removed to cast the next bin, the supporting screw is retracted and the side formwork is pulled to rotate around the hinge point so as to separate from the concrete surface; then the first hydraulic cylinder is controlled to retract, the bottom formwork is lifted, and it is pulled away from the concrete surface to achieve demolding. At this time, the formwork is installed on the formwork truss. The formwork truss is then controlled to roll along the supporting truss to the next working section to achieve the movement of the formwork truss and the formwork. When it is necessary to cast again, it is only necessary to readjust the first hydraulic cylinder and the supporting screw to achieve the rapid installation of the formwork. Compared with the traditional aqueduct inner formwork support system, this application does not require the formwork and formwork truss to be repeatedly disassembled during operation, and the formwork is convenient to move, which effectively improves construction efficiency and saves construction costs.

DETAILED DESCRIPTION

[0021] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0022] Example

[0023] like Figure 1-4 As shown, a cast-in-place movable aqueduct inner form support system includes a formwork, a formwork truss and a support truss; the formwork truss can roll along the support truss; the formwork is formed by hinged side formwork 5 and bottom formwork 6 on both sides; a first hydraulic cylinder 10 is installed at the bottom of the formwork truss, and the bottom of the first hydraulic cylinder 10 is fixedly connected to the bottom formwork 6; the two ends of the support screw rod 3 are respectively hinged to the side formwork 5 and the two sides of the formwork truss.

[0024] In the aforementioned cast-in-place movable aqueduct inner formwork support system, when the formwork needs to be removed to cast the next bin, the support screw 3 is retracted, and the side formwork 5 is pulled to rotate around the hinge point, thereby separating from the concrete surface. The first hydraulic cylinder 10 is then controlled to retract, lifting the bottom formwork 6 and pulling it away from the concrete surface to achieve demolding. At this point, the formwork is all installed on the formwork truss. The formwork truss is then controlled to roll along the support truss to the next working section, achieving the movement of the formwork truss and formwork. When pouring again is required, only the first hydraulic cylinder 10 and the support screw 3 need to be readjusted to achieve rapid installation of the formwork.

[0025] Specifically, to enable the formwork truss to roll along the support truss and reduce frictional resistance, the support truss includes two parallel, back-to-back double-channel steels 9; the formwork truss includes a crossbeam 1 and a column 4; a support screw 3 is mounted on the side of the column 4; a first hydraulic cylinder 10 is mounted at the bottom of the column 4; a rolling mechanism 2 is mounted at both ends of the lower end surface of the crossbeam 1; the rolling mechanism 2 includes an open housing 201 fixed to the lower end surface of the crossbeam 1; a fixed shaft 202 is mounted within the open housing 201; a first roller 203 is rotatably mounted on the fixed shaft 202; the upper portion of the back-to-back double-channel steels 9 is inserted into the open housing 201; and the first roller 203 can roll along the upper surface of the back-to-back double-channel steels 9. Before moving the formwork truss, the first hydraulic cylinder has already retracted and lifted the bottom formwork. At this time, the formwork truss and formwork are pressed against the back-to-back double-channel steels 9 under the action of gravity, and the first roller 203 is in contact with the upper surface of the back-to-back double-channel steels 9. At this point, pushing the formwork truss will move the formwork truss and formwork until they move to the next work section. The provision of the rolling mechanism 2 can effectively reduce the frictional resistance during the movement of the formwork truss, facilitating the movement of the formwork truss and formwork, significantly reducing the workload and improving construction efficiency.

[0026] Specifically, in order to save costs and realize the movable support of the back-to-back double channel steel 9, the span of the support truss is at least the casting length of three bins; the support truss also includes a support beam 11 and a support column 8 fixed to the support beam 11; the back-to-back double channel steel 9 is installed on the support column 8; the lower end of the support beam 11 is installed with a second hydraulic cylinder 7; the span of the second hydraulic cylinder 7 is the casting length of one bin and is located on one side of the support truss; the bottom of the second hydraulic cylinder 7 is fixedly mounted on the base 16. When starting the operation, the first bin needs to be cast in advance. Then the support truss is erected on the first bin. In other words, the base 16 is supported on the concrete after the first bin has been cast and has reached the concrete strength. The formwork truss and formwork are installed in the second bin for casting. When the second chamber is finished pouring, the formwork truss is moved to the third chamber. Once the concrete reaches the required strength, the second hydraulic cylinder 7 is controlled to retract, lifting the support truss. Gravity forces the support truss to hang from the formwork truss, with the upper and lower end surfaces of the back-to-back double channel steels 9 serving as the support points between the two. At this point, the support truss is pushed forward one working section. The second hydraulic cylinder 7 is then controlled to extend, allowing the support truss to rest on the already formed concrete in the second chamber. The previous operation is then repeated to pour the third chamber. This reciprocating motion completes the pouring of all subsequent sections.

[0027] Specifically, to facilitate movement of the support truss and reduce resistance, brackets 204 are mounted on both sides of the opening of the housing 201. Second rollers 205 are rotatably mounted on the brackets 204. The vertical distance between the first roller 203 and the second roller 205 is greater than the thickness of the upper portion of the back-to-back double channel steel 9. The provision of the second rollers 205 converts resistance during movement of the support truss into rolling friction, thus saving effort.

[0028] Specifically, in order to improve the stability of the support truss, a counterweight 19 is installed at one end of the support beam 11 close to the second hydraulic cylinder 7. The support truss itself is an eccentric structure, so the added counterweight 19 can balance the center of gravity well and improve stability.

[0029] Specifically, to further improve the stability of the support truss, the base 16 is connected to the climbing cone 17 embedded in the aqueduct via bolts 18. The connection between the bolts 18 and the embedded climbing cone 17 can provide tension to improve the stability of the support truss and prevent the support truss from moving.

[0030] Specifically, a connection box 12 is fixedly connected between the bottom of the first hydraulic cylinder 10 and the bottom template 6 .

[0031] Specifically, a weight-reducing hole 15 is provided on the connection box 12 .

[0032] Specifically, in order to improve the support strength, fixed support rods 20 are fixed between the columns 4, and support diagonal rods 21 are fixed between the fixed support rods 20 and the columns 4. Both the fixed support rods 20 and the support diagonal rods 21 can improve the resistance during pouring.

[0033] Specifically, in order to further improve the supporting strength, a set 14 is installed on the column 4, and a detachable support rod 13 is detachably installed between the sets 14. The detachable setting is for easy disassembly and assembly, and can be quickly removed when not pouring, providing a wider working space for the operator.

[0034] Working principle of the present invention:

[0035] To begin construction, the first chamber must be cast in advance. The support truss is then installed on the first chamber. This means the base 16 supports the concrete after the first chamber has been cast and reached concrete strength. The formwork truss and formwork are installed in the second chamber. The support screw 3 and first hydraulic cylinder 10 are adjusted to position the formwork in the desired position before pouring. When the second chamber is finished pouring, the support screw 3 is retracted, pulling the side formwork 5 around its hinge point and releasing it from the concrete surface. The first hydraulic cylinder 10 is then retracted to lift the bottom formwork 6, pulling it away from the concrete surface and releasing it. At this point, both forms are attached to the formwork truss. The formwork truss is then rolled along the support truss to the third chamber. The first hydraulic cylinder 10 and support screw 3 are then readjusted to quickly install the formwork. Once the second chamber reaches concrete strength, the second hydraulic cylinder 7 is retracted to lift the support truss. The support truss is then suspended from the formwork truss by gravity, with the upper and lower end surfaces of the back-to-back double channel steels 9 serving as support points. At this point, the support truss is pushed forward one working section. The second hydraulic cylinder 7 is then extended, allowing the support truss to rest on the already formed concrete in the second chamber. The previous operation is repeated to pour the third chamber. This cycle continues until all subsequent sections are poured.

It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
