Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a three-section adjustable square and round buckle reinforcement device. Background Technology

[0002] The Fangyuan buckle, also known as a square column fastener, is a new type of building material that has become popular in recent years. It consists of four single-piece galvanized steel plates with corresponding bends. One end of each plate is bent, and each plate has several evenly spaced fixing holes along its length. Wedge-shaped fixing pins pass through the round holes and fixing holes to secure the limiting sleeve and the plate, forming a formwork reinforcement device that is easy to install and disassemble. It is not only simple in structure but also easy to install. Workers using the Fangyuan buckle can reinforce a column formwork in just 20 minutes. Therefore, the Fangyuan buckle has been welcomed by many construction sites since its introduction. The high-quality steel used in the Fangyuan buckle is highly resistant to pressure and deformation. It is simple and easy to install, does not slip, and does not leak grout. It solves the problem of reinforcing formwork, saves time in installing reinforced square columns, shortens the construction period, and saves costs.

[0003] The existing square and round buckle fixing holes are generally spaced about 5cm apart. This means that the structural size applicable to the same set of square and round buckles can only increase from the minimum reinforcement size of the square and round buckle to the maximum adjustable size in an arithmetic sequence. The adjustable value is not precise enough. In addition, the clamping plate is generally 80mm to 100mm wide. In addition, the wooden square outside the template serves as a supporting keel, which requires a certain amount of space when setting up the formwork. When encountering the problem of small spacing between adjacent structures, the existing square and round buckles cannot close and fix them. Summary of the Invention

[0004] The purpose of this invention is to provide a three-section adjustable square and round buckle reinforcement device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a three-section adjustable square and round buckle reinforcement device, comprising locking components, wherein the locking components are provided in several groups, each group of locking components including a first locking plate, two second locking plates and two third locking plates, one end of the lower side of the two second locking plates is engaged with the upper side of the left and right ends of the first locking plate, and the two second locking plates are arranged in parallel, the other end of the upper side of the two second locking plates is engaged with the lower end of the third locking plate respectively, the two third locking plates are connected by a pull screw, and several reverse teeth are fixedly installed on the left and right sides of the upper end of the first locking plate, and a sliding groove is opened in the left and right direction on the first locking plate, the sliding groove penetrating the sidewalls of the upper and lower ends of the first locking plate and the reverse teeth;

[0006] Several reverse teeth are evenly fixed on one side of the upper end of the clamping plate 2. A sliding groove 2 is opened on one side of the clamping plate 2.

[0010] Preferably, a fixing plate is fixedly installed on the upper end of one of the two card plates away from the side of the reverse tooth two. A circular hole is opened on the side wall of the fixing plate one. The circular holes on the fixing plate one and the fixing plate two are the same size and their centers are on the same horizontal line.

[0011] Preferably, one end of the first card plate is close to the outer side of one of the templates, and the threaded post one at the lower end of the two second card plates passes through the groove one on the first card plate and slides inward, so that the inner end of the second card plate contacts the outer side of the other two templates.

[0012] Preferably, the lower end of the threaded post 2 at the lower end of the card plate 3 passes through the sliding groove 2 on the card plate 2 and slides inward until the inner end of the card plate 3 contacts the outer wall of the wooden block on the outer side of the template, and the reverse tooth 4 at the lower end of the card plate 3 and the reverse tooth 2 at the upper end of the card plate 2 mesh with each other, and a nut is threadedly connected to the lower end of the threaded post 2.

[0013] Preferably, the left and right ends of the pull screw one pass through the round holes on the fixing plate three and are threaded with nuts.

Different reverse tooth spacings are set to control the adjustable value of the reinforceable size of each set of square and round buckles. When using this device, only three sides have square and round buckles. When used on the side with shorter structural spacing, tie bolts are used to reinforce the structure instead of square and round buckles, solving the problem of template reinforcement when structural dimensions are close. It is also more convenient to operate and has lower production costs. Attached Figure Description

By tightening the nut, the clamping plate 1 3 is pulled towards the side of the wooden block 2, so that the clamping plate 1 3 and the clamping plate 3 13 are in close contact with the wooden block outside the template 1, thereby firmly fixing the template 1 and preventing the formwork from bulging or leaking during concrete pouring.

[0033] During operation, the device connects four templates 1 end-to-end to form a pouring cavity, according to the on-site construction conditions. Wooden blocks 2 are fixedly installed on the outside of the templates 1. One end of clamping plate 3 is placed close to the wooden block 2 on the outside of one of the templates 1. The threaded posts 10 at the lower ends of two clamping plates 6 pass through the sliding grooves 5 on clamping plate 3 and slide inwards, so that the inner end of clamping plate 6 contacts the wooden blocks 2 on the outside of the other two templates 1. The lower end of the threaded post 17 at the lower end of clamping plate 3 passes through the sliding groove 8 on clamping plate 6 and slides inwards until the inner end of clamping plate 3 13 contacts the outer wall of the wooden block 2 on the outside of the template 1. The reverse teeth 16 at the lower end of clamping plate 3 13 and the reverse teeth 7 at the upper end of clamping plate 6 mesh with each other. A nut is threaded onto the lower end of the threaded post 17, fixing one end of clamping plate 3 13 and clamping plate 2 6. The left and right ends of the tie rod 18 are then passed through the fixing... The round hole 11 on plate 3 15 is threaded with a nut. By tightening the nut, the two clamping plates 3 13 are pulled inward and fixed. At the same time, one end of the two clamping plates 2 6 is pulled inward. Then, the other end of the clamping plate 2 6 is pushed inward, so that the clamping plate 2 6 tightly fixes the wooden blocks 2 at both ends of the template 1 inward, and makes the reverse teeth 3 9 and reverse teeth 1 4 at the lower end of the clamping plate 2 9 mesh with each other. The lower end of the threaded column 10 is threaded with a nut, so that the clamping plate 2 6 is fixed. Then, one end of the tie rod 2 19 passes through the round hole 11 on the fixing plate 2 14 and the fixing plate 1 12 in sequence and is threaded with a nut. By tightening the nut, the clamping plate 1 3 is pulled to one side of the wooden block 2, so that the clamping plate 1 3 and the clamping plate 3 13 are in close contact with the wooden blocks outside the template 1, so that the template 1 is firmly fixed and the bulging or leakage of the template occurs when pouring concrete.
