Description

Technical Field

[0001] The invention relates to the technical field of civil engineering template construction, in particular to a template reinforcement construction method. Background Art

[0002] In the process of civil engineering formwork construction, the processing, production, installation and fixation of the formwork has always been a time-consuming and laborious construction process depending on the construction structure. Figure 1 , Figure 2 As shown, holes are reserved on the templates on both sides. After the reinforcement is tied, tension bolts are inserted into the templates on both sides, and the tension bolts are fixed with the mountain-shaped clips (butterfly buckles) and nuts at both ends. A top formwork support system is added between the tops of the templates on both sides to prevent the template from expanding due to lateral pressure during concrete pouring. However, the above method has relatively high requirements for the installation quality of the tension bolts. If the tightening degree or spacing of the tension bolts is not set reasonably, it is easy to cause the template to deform and leak, which will bring difficulties to the construction and affect the construction progress. In addition, the above method requires a large number of materials such as tension bolts, and the construction cost is high. Summary of the invention

[0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a formwork reinforcement construction method, which can simplify the construction process, greatly shorten the construction time, and reduce the construction cost.

[0004] The technical solution adopted by the present invention to solve its technical problem is: A formwork reinforcement construction method is carried out according to the following steps; S1. After the steel frame is tied, determine the reinforcement support points on the steel frame according to the construction drawings, and reserve corresponding through holes on the side formwork according to the positions of the reinforcement support points; S2. According to the position of the reinforcement support point, a connecting rod is correspondingly arranged on the steel skeleton, and the connecting rod corresponds to the through hole reserved on the side formwork one by one; S3. According to the installation distance between the side formwork and the steel bar skeleton, the top plate is fixedly connected to each connecting rod, and the top plate is in contact with the inner wall of the side formwork; S4. Install the side formwork. During installation, the connecting rods pass through the reserved through holes on the side formwork one by one, and then the clamping parts and the main keel are installed. The formwork reinforcement is completed.

[0005] Compared with the prior art, the present invention has the following beneficial effects: The present invention can save a large amount of construction materials such as steel bars and tension bolts, and at the same time, reinforced support points are added to the steel frame without the need for through-installation of tension bolts, so that the template is more evenly stressed, avoiding template deformation and slurry leakage, improving construction quality and reducing construction costs.

[0006] Further, the preferred embodiment adopted by the present invention is: The connecting rod is connected to the stirrups or horizontal bars of the steel skeleton. According to the location of the reinforcement support point determined, stirrups or horizontal bars are selected and welded to the connecting rod. The card connector is a mountain-shaped card.

[0007] The main keel is a steel tube structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0009] The specific implementation modes of the present invention are described below in conjunction with specific embodiments to further illustrate the present invention. The purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0010] A formwork reinforcement construction method, such as Figures 3 to 5 As shown, taking the column as the main structure as an example, when reinforcing the formwork of the column, the specific steps are as follows: S1. Determine the reinforcement support points of the already tied steel bar skeleton 1 according to the construction drawings, and reserve corresponding through holes on the side formwork 2 according to the positions of the reinforcement support points on the steel bar skeleton 1.

[0011] S2. According to the position of the reinforcement support point determined in step S1, a screw rod of appropriate length is cut as the connecting rod 4, and one end of the connecting rod 4 is welded to the steel skeleton 1 at the position corresponding to the reinforcement support point. During welding, the connecting rod 4 is welded to the stirrups 101 or horizontal bars 102 of the steel skeleton 1 at the corresponding position; and the connecting rods 4 correspond one-to-one to the through holes reserved on the side formwork 2, and the other end of each connecting rod 4 passes through the side formwork 2.

[0012] S3. A top plate 5 is provided on each connecting rod 4, and a through hole is opened in the center of the top plate 5. After the connecting rod 4 passes through the through hole, the installation position of the top plate 5 on the connecting rod 4 is adjusted. The installation position of the top plate 5 is determined by the installation distance between the inner wall of the side formwork 2 and the outer surface of the steel skeleton 1, and then the top plate 5 is welded and fixed to the connecting rod 4 where it is located.

[0013] S4. Install the side formwork 2. When installing the side formwork 2, the connecting rods 4 need to pass through the through holes reserved on the side formwork 2 one by one, and then install the clamping parts 6 and the main keel 3 on the outside of the side formwork 2; the clamping parts 6 in this embodiment are mountain-shaped clamps, and are locked by nuts on the outside of the clamping parts 6; in this embodiment, the main keel 3 is fixed to the outside of the side formwork 2 by nuts and clamping parts 6.

[0014] According to the method, materials can be obtained on-site to make the connecting rod 4. According to the construction drawings and construction requirements, steel bars of appropriate diameter are selected, and the connecting rod 4 is made by cutting appropriate lengths. The side formwork 2 is fixed inside and outside, which greatly shortens the construction process of the formwork reinforcement. There is no need for through-type tension fixation, which reduces the difficulty of repair after the later construction. Multiple reinforcement support points are added to the steel skeleton 1, so that the side formwork 2 is more evenly stressed, avoiding deformation of the formwork and leakage of slurry, and improving the molding quality.

[0015] The above description is only the preferred embodiment of the present invention, and does not limit the scope of rights of the present invention. All equivalent changes made by using the contents of the present invention specification and its drawings are included in the scope of rights of the present invention.
