Description

Technical Field

[0001] This utility model relates to a construction device, specifically a construction device for making and installing ring-shaped stirrups. Background Technology

[0002] A circular independent foundation is a cylindrical, single-load-bearing structure mainly used to bear the vertical load of the superstructure (such as power equipment such as reactors, transmission towers, and industrial equipment) and transfer it to the foundation. Due to its advantages such as reasonable stress distribution, economic efficiency, and convenient construction, the circular independent foundation is widely used in the fields of power, transportation, and industrial buildings.

[0003] Currently, during the construction of circular independent foundations, after the longitudinal main reinforcement bars are tied, it is necessary to fabricate and install ring stirrups. Usually, the construction workers first manually fabricate the ring stirrups of the required size, and then install the ring stirrups layer by layer along the height direction of the longitudinal main reinforcement bars. When installing ring stirrups at different heights, the construction workers need to first erect temporary support frames of the corresponding height. Erecting temporary support frames is both time-consuming and labor-intensive, which seriously affects the construction efficiency and also greatly increases the labor intensity of the construction workers. Summary of the Invention

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a construction device for manufacturing and installing ring stirrups, thereby improving construction efficiency and reducing the labor intensity of construction workers.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a construction device for manufacturing and installing ring stirrups, comprising a support mechanism, a lifting mechanism installed on the support mechanism that can reciprocate along the vertical direction, and a forming and positioning mechanism rotatably connected to the top of the lifting mechanism that can manufacture and position the ring stirrups.

[0006] As a limitation of this utility model, the support mechanism includes a vertically arranged support body supported on the ground by at least two diagonal bracing members.

[0007] As a further limitation of this utility model, the lifting mechanism includes a rack member mounted on the support body via a sliding member, a rotating shaft rotatably mounted on the support body, a drive gear fixed on the rotating shaft and meshing with the rack member, and an operating handle fixed on the rotating shaft.

[0008] As a further limitation of this utility model, the lifting mechanism also includes a locking mechanism provided on the bracket body for restricting the rotation of the rotating shaft. When the locking mechanism is in the unlocked state, the rotating shaft can rotate, and when the locking mechanism is in the locked state, the rotating shaft cannot rotate.

[0009] As a further limitation of this utility model, the locking mechanism includes a bolt threadedly connected to the bracket body and extending to the inner side of the bracket body, a locking toothed plate rotatably disposed at the end of the bolt and capable of meshing with a drive gear, and a plurality of limiting slide rods disposed between the locking toothed plate and the bracket body; the limiting slide rods are slidably connected to the bracket body, wherein one end of the limiting slide rod is located inside the bracket body and fixedly connected to the top of the locking toothed plate, and the other end is located outside the bracket body.

[0010] As another limitation of this utility model, the forming and positioning mechanism includes a support plate rotatably disposed on the top of the lifting mechanism, a disc fixed at the center of the support plate, and a plurality of positioning rod components arranged radially along the circumference of the disc; the positioning rod components are provided with a plurality of positioning grooves that can position the annular stirrups at intervals, and the corresponding positioning grooves on the plurality of positioning rod components are arranged along the circumference.

[0011] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: (1) This utility model is provided with a support mechanism, a lifting mechanism and a forming and positioning mechanism. The forming and positioning mechanism can both produce and position the ring stirrups. When using it, the ring stirrups can be produced by the forming and positioning mechanism first, and then the produced ring stirrups can be positioned on the forming and positioning mechanism. Finally, the ring stirrups can be lifted to the required height by the lifting mechanism and then the ring stirrups can be tied and installed. During the installation of the ring stirrups, there is no need to set up a temporary support frame in advance. The production and installation of the ring stirrups can be completed quickly, saving time and effort, and effectively improving construction efficiency and reducing the labor intensity of construction personnel.

[0012] (2) The support mechanism of this utility model includes at least two diagonal bracing members and a support body. The at least two diagonal bracing members can stably support the support body on the ground. Under the premise of ensuring structural stability, all components in the support mechanism are conventional components that are easy to obtain and can reduce manufacturing costs.

[0013] (3) The lifting mechanism in this utility model has a reasonable structure and is easy to use. When using it, first adjust the locking mechanism to the unlocked state, then turn the operating handle to lift the ring hoop positioned on the forming positioning mechanism to the required installation height, and finally adjust the locking mechanism to the locked state. At this time, the ring hoop can be tied and installed.

[0014] (4) The locking mechanism in this utility model adopts a structure combining a locking toothed plate, multiple limiting slide rods, and bolts. The structure is safe, reliable, and easy to operate. When it is necessary to restrict the rotation of the shaft, simply rotate the bolt to make the locking toothed plate tightly mesh with the drive gear. At this time, the drive gear is locked and cannot rotate, and the shaft cannot rotate either. The corresponding rack component can then be positioned at the required position. When it is necessary to raise or lower the lifting mechanism, simply rotate the bolt in the opposite direction until the locking toothed plate disengages from the drive gear. Then, rotating the operating handle will allow the lifting mechanism to complete the raising or lowering.

[0015] (5) The structural design of the forming and positioning mechanism in this utility model is ingenious. When making the ring stirrup, according to the size of the ring stirrup, one end of the coiled steel bar is firmly inserted into a positioning groove at the corresponding size position. Then, while rotating the forming and positioning mechanism, the steel bars are inserted into the corresponding positioning grooves distributed along the circumference until the steel bars are formed into a ring stirrup. When installing the ring stirrup, the ring stirrup is firmly inserted into the positioning grooves distributed along the circumference at the corresponding size position. At this time, the positioning of the ring stirrup is completed. This utility model integrates the making and installation of the ring stirrup, which can ensure that the made ring stirrup can be firmly inserted into the forming and positioning mechanism, and can effectively improve the structural reliability of this utility model when in use.

[0016] In summary, this utility model features an ingenious structural design, low manufacturing cost, ease of use, and strong practicality. It can both fabricate and position ring-shaped stirrups. After fabrication, the ring-shaped stirrups can be installed and positioned on a forming and positioning mechanism. Then, a lifting mechanism elevates the ring-shaped stirrups to the required height, allowing for their binding and installation. During installation, there is no need to erect temporary support frames beforehand, enabling rapid fabrication and installation, saving time and labor, effectively improving construction efficiency and reducing the workload of construction workers. This utility model is suitable for use in the construction of circular independent foundations. Attached Figure Description
