Description

Technical Field

[0001] The patent of the present invention is an adjustable support device for arc-shaped reserved hole concrete formwork, which is suitable for supporting arc-shaped, elliptical and circular concrete hole formwork. After being assembled on the ground, the device is directly installed in the hole for fine adjustment, which can conveniently and efficiently support, fix and disassemble the arc-shaped hole concrete formwork. Background Art

[0002] The traditional construction of arc-shaped reserved openings generally uses concrete formwork support. This traditional process has the following defects: 1. Generally, steel support or scaffolding tube support formwork is used. During the installation process, the appropriate scaffolding tube length needs to be cut to adapt to the size and shape of the arc-shaped opening, which leads to material waste. The scaffolding tube cut to the size of the opening cannot be reused, which does not meet the national green construction requirements. 2. There are many loose parts, and workers need to install and disassemble the steel support or scaffolding tube support of the high opening on site. The materials are scattered, the erection cycle is long, and the workers' technical level is required to be high. There is a risk of falling objects from high altitude. 3. For large openings, the erection cannot be completed at one time. It is necessary to gradually erect the scaffolding top support formwork in sections according to the construction progress until the opening is formed. In summary, the construction of traditional opening formwork support is time-consuming, labor-intensive, costly, and has high safety risks. Summary of the invention

[0003] The invention provides an adjustable support device for an arc-shaped reserved hole concrete formwork, which can adapt to the diameter and thickness of the designed hole. The device is first assembled and adjusted and then placed in the center of the arc-shaped concrete hole. Only two points of support are needed for temporary support for positioning and fixing. Subsequently, the support rods are continuously adjusted and tightened to the formwork around the hole according to the progress of the hole construction. The longitudinal adjustment accuracy of the support rods is high, ensuring that the fixed shape of the formwork of the entire arc-shaped hole meets the requirements of the drawings. After the hole construction is completed, only the tightened support rods need to be loosened to remove the support device as a whole. Installation and disassembly are quick, which solves the problem of long construction period of traditional scaffolding support and high risk of falling objects during disassembly.

[0004] The device is composed of a support ring, a fixed clamp block, a support rod, and a support plate. The two support rings are clamped and fixed by the fixed clamp block, and the support rod adjustment screw is screwed into the thread hole of the fixed clamp block for adjustment. The upper part of the support rod is inserted into the hollow short tube welded at the center of the bottom of the support plate; the fixed clamp block consists of a clamping plate on each side and a thread hole with internal threads in the center. After clamping the support ring, it is fixed and tightened with bolts. According to the size of the arc hole, the support rod is rotated to adjust the external extension, and different clamp blocks and support rod quantities are selected according to the size of the hole.

[0005] The technical solution adopted by the patent of the present invention to solve its technical problems is as follows: the device is mainly composed of a support ring, a fixed clamp block, a support rod, and a support plate.

[0006] Support ring: This part consists of a pair of support rings. The specific size is selected according to the arc-shaped hole and is clamped and fixed by a fixing clamp.

[0007] Fixed clamp block: A movable component used in conjunction with the support ring, consisting of a fixed block in the middle and cover plates on both sides. Bolts are used to fasten the fixed block and the cover plates on both sides. The threaded hole in the center of the fixed block can be inserted to tighten the support rod and adjust the extension length.

[0008] Support rod: A vertical rod with an adjustment thread on one end. The number is usually selected according to the size of the arc hole.

[0009] Support plate: It is composed of a support plate and a hollow short tube welded at the bottom center. Support plates of different sizes are selected according to the thickness of the different openings. The support rod is inserted into the hollow short tube to support the opening template.

[0010] After the overall assembly, the device is placed at the hole position, the extension length of the support rod is adjusted according to the hole template, and the template is tightened and fixed.

[0011] The whole device is composed of detachable parts, which is easy to load and unload, easy to transfer and transport, and can be used repeatedly.

[0012] The structural material selection has been optimized many times and has a strong load-bearing capacity. Different numbers of support rods and fixing blocks can be set according to the size of the opening to adapt to the size of the opening. The extension length of the support rods can be adjusted to tighten and fix the formwork. It is easy to operate and the formwork support work can be carried out conveniently and efficiently.

[0013] The beneficial effects of the invention patent: the device provides a stable and reliable steel structure frame with strong supporting capacity and can effectively fix the formwork; the structure is simple and practical, and it is easy to assemble, disassemble and replace, which can effectively reduce the workload and labor costs, reduce the amount of high-altitude operations, and reduce the risk of high-altitude parts falling. The device is easy to use and versatile, easy to transfer and transport, can be used repeatedly, avoids material waste, meets the requirements of national green construction, and has good technical and economic benefits and promotion and application value.
