Description

Technical Field

[0001] The utility model relates to the technical field of formwork, in particular to a shear wall formwork without punching holes. Background Technique

[0002] With the continuous development of the construction industry, more and more new types of formwork, such as aluminum formwork, steel formwork, plastic formwork, etc., are continuously promoted and applied. However, due to cost and other factors, the formwork reinforcement systems of most current construction projects still use the traditional method of perforating and reinforcing inside wooden formwork. However, drilling greatly reduces the original anti-deformation ability of the wooden formwork. Due to water absorption at the holes, the formwork swells wetly, making it prone to bending, deformation, and breakage during use, reducing the service life of the formwork.

[0003] During the construction of the basement of the project, a construction method for shear wall formwork without punching holes was innovatively developed. Through practice, this construction method avoids punching holes inside the wooden formwork, greatly improves the formwork turnover times, is safe and reliable, convenient for construction, has high work efficiency, good forming effect, and remarkable economic and social benefits. Content of the Utility Model

[0004] The purpose of the utility model is to provide a shear wall formwork without punching holes to solve at least any one of the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a shear wall formwork without punching holes, including four first wooden formworks, eight second wooden formworks, and multiple tie bolts. The eight second wooden formworks are evenly distributed between the four first wooden formworks, and the multiple tie bolts are evenly distributed between the four first wooden formworks and the eight second wooden formworks. The multiple tie bolts are respectively detachably connected to the adjacent first wooden formwork or second wooden formwork.

[0006] Preferably, multiple steel pipes are arranged between the four first wooden formworks and the eight second wooden formworks. The multiple steel pipes are evenly distributed between the four first wooden formworks and the eight second wooden formworks, and the multiple steel pipes respectively abut against the four first wooden formworks and the eight second wooden formworks.

[0007] Preferably, multiple fastening strips are arranged on the four first wooden formworks and the eight second wooden formworks. The multiple fastening strips are respectively detachably connected to the four first wooden formworks and the eight second wooden formworks.

[0008] Preferably, multiple fastening rods are arranged on the multiple tie bolts. The multiple fastening rods respectively abut against the multiple fastening strips and the multiple tie bolts.

[0009] The beneficial effects of the utility model are as follows:

[0010] In the present utility model

[0011] Avoid punching holes inside the formwork, significantly increasing the turnover times. Compared with the traditional method of using scattered wood formwork for shear walls, the non-punching shear wall formwork system does not require opening holes inside the wood formwork, effectively avoiding the deformation caused by punching itself and the wet expansion deformation caused by water absorption at the holes, significantly increasing the formwork turnover times and reducing construction costs;

[0012] The construction is convenient and the work efficiency is high. When constructing the non-punching shear wall formwork, it is installed layer by layer synchronously from both sides at the bottom and fasteners are set. Finally, the vertical secondary keels are erected and tightened with fasteners to the main keel. The formwork installation and disassembly are convenient, and the construction work efficiency is significantly improved;

[0013] The forming effect is good. When the non-punching shear wall formwork is reinforced, the tension force points of the tie bolts are all located at the joint seams of the upper and lower layers of formwork, that is, the first wood formwork and the second wood formwork, which can effectively avoid the phenomenon of offset. After demoulding, the bolt holes are arranged in a straight line, and the overall appearance is beautiful. After local treatment, the effect of thin plastering or plastering-free leveling of the wall surface can be achieved. Description of the Drawings

[0020] The present utility model provides as Figures 1-4A kind of punching-free formwork for shear walls shown in the figure includes four first wooden formworks 1, eight second wooden formworks 3 and multiple tie bolts 4. The eight second wooden formworks 3 are evenly distributed between the four first wooden formworks 1. The multiple tie bolts 4 are evenly distributed between the four first wooden formworks 1 and the eight second wooden formworks 3. The multiple tie bolts 4 are respectively detachably connected to the adjacent first wooden formwork 1 or second wooden formwork 3. A plurality of steel pipes 6 are arranged between the four first wooden formworks 1 and the eight second wooden formworks 3. The multiple steel pipes 6 are evenly distributed between the four first wooden formworks 1 and the eight second wooden formworks 3.

It performs excellently in the forming effect. When the punching-free shear wall formwork is reinforced, the tie force points of the tie bolts 4 are all at the joints of the upper and lower layers of formwork, that is, at the first wooden formwork 1 and the second wooden formwork 3, which can effectively avoid the phenomenon of offset. After demoulding, the bolt holes are arranged in a neat line, and the overall appearance is very beautiful. After local treatment, a good effect of thin plastering or even plastering-free leveling of the wall surface can be achieved.
