Description

Technical Field

[0001] The utility model relates to a template system for an external wall, in particular to a template system for a basement external wall without opening a hole. Background Art

[0002] In housing construction projects, the basement exterior walls are usually quite high. When designing the formwork, the formwork system usually includes wooden formwork, tie-stop bolts, vertical ribs, horizontal ribs and other components. In the construction of the exterior wall formwork, the spacing between the tie-stop bolts is generally smaller than the formwork size, so it is necessary to open the tie-stop bolt holes in advance on the wooden formwork.

[0003] (1) After the traditional method of formwork removal, many tension bolt holes are left on the surface of the exterior wall. The common problem of penetration caused by loose sealing of the tension bolt holes often occurs in housing construction projects;

[0004] (2) In the traditional method, wooden formwork is used as a turnover material. During the process of supporting the exterior wall, many holes for tension bolts are left, which makes it impossible to use it in other parts that do not require tension bolts (such as beams, slabs and columns), affecting the secondary turnover and causing economic losses.

[0005] Therefore, how to optimize and improve the existing template system without affecting the stability of the template system is an urgent problem to be solved. Utility Model Content

[0008] The above-mentioned formwork system for basement exterior walls without opening holes, wherein a steel pipe is provided on each side of the rectangular wood, and the steel pipe is tightly fitted together with the wooden formwork and the tensioning water-stop screws in a locked and fixed state.

[0009] The above-mentioned formwork system for basement exterior walls without opening holes, wherein reinforcing double nuts are provided at both ends of the tension water-stop screws.

[0010] The above-mentioned formwork system for basement exterior walls without opening holes, wherein the diameter of the steel pipe is 40 mm.

[0011] The above-mentioned formwork system for basement exterior walls without opening holes, wherein the spacing between the tension bolt holes is 230 mm, and the width of the rectangular wood is 60 cm.

[0012] The above-mentioned formwork system for basement exterior walls without opening holes, wherein the joints of two adjacent wooden formworks corresponding to the two sides of the wall are located in the same plane, so that each tensioning water-stop screw passes through the wall horizontally.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a formwork system for basement exterior walls that does not require opening holes, adds a long wooden square at the joint between every two formworks, and the tension bolt holes are set on the long wooden square; no tension bolt holes are set on the wooden formwork, reducing the workload of hole sealing, thereby reducing the risk of leakage on the basement exterior wall; at the same time, the integrity of the wooden formwork is guaranteed, and the secondary turnover use is not affected.
