Description

Retractable Formwork Support Rods

technical field

The utility model relates to a support rod of a formwork used in concrete pouring in the construction field.

Background technique

When pouring concrete, the formwork used for the pouring facade needs to be supported by support rods to maintain the accuracy and firmness of the formwork installation. According to the installation angle of the formwork, in some cases, the formwork not only needs to be supported by support rods, but also needs to be cable-stayed. Most of the existing support methods are directly supported by steel pipes or wooden poles. Due to their fixed length, the adjustment accuracy is poor, the installation is inconvenient, and the firmness is not easy to control.

Contents of the invention

The purpose of the utility model is to provide a template support rod which is simple and quick to install and can maintain the accuracy and firmness of the template installation.

The technical scheme of the utility model is as follows:

A telescopic formwork support rod is characterized in that: it includes a steel pipe, the two ends of the steel pipe are provided with internal threads; it also includes a first screw rod, the upper end of the first screw rod is provided with a screw hole, and the lower end is connected to the One end of the steel pipe is screwed; it also includes a second screw rod, the upper end of the second screw rod is screwed with the other end of the steel pipe, and the lower end is a plane base, and a through hole is provided on the base.

Furthermore, the technical solution of the present invention also includes: a force-receiving hole is provided in the middle part of the steel pipe.

The utility model has a retractable structure, quick installation, high adjustment precision, good stability and firmness, and integrates the functions of support and cable pull. Through the screw connection between the steel pipe and the screw rod, the length of the support rod can be adjusted; through the screw hole at the upper end of the first screw rod, the screw rod can be quickly and firmly connected with the template, and through the flat base at the bottom of the second screw rod, It can be stably fixed to the ground.

Detailed ways

As shown in Figure 1, the utility model comprises a steel pipe 1, and the two ends of described steel pipe 1 are provided with internal thread; It is screwed with one end of the steel pipe 1; it also includes a second screw rod 2, the upper end of the second screw rod 3 is screwed with the other end of the steel pipe, and the lower end is a flat base 31, and the base is provided with Through hole 32 .

With the above structure, the length of the support rod can be adjusted through the rotation cooperation between the first screw rod 2 and the second screw rod 3 and the steel pipe 1 .

During specific implementation, a force-receiving hole 11 can be set in the middle of the steel pipe. When the length needs to be adjusted, a steel rod is inserted into the force-receiving hole 11 on the steel pipe. By rotating the steel rod, the rotation of the steel pipe can be made more convenient and labor-saving.

Fig. 2 is a diagram of the use status of the utility model. When in use, the flat base 31 at the bottom of the second screw mandrel 3 is placed flat on the ground 7. The ground mentioned here is generally a concrete surface during actual construction. Through the through hole 32 on the base, the expansion screw 4 is inserted into the ground 7, so that the utility model can be firmly fixed with the ground. Through the rotation of the steel pipe 1, the supporting rod is adjusted to an appropriate length; through the screw hole 21 at the upper end of the first screw rod 2, the screw rod 5 is firmly connected with the template 6.

The utility model combines the support and the cable-stay, and has the advantages of fast installation, high adjustment precision, good stability and firmness.
