Problems solved by technology

This construction method is likely to cause defects such as inaccurate positioning of the curved beam structure and poor appearance quality, and also increases the workload and cost of concrete surface repair
[0003] In addition, the arc-shaped beam formwork used in the construction of arc-shaped beams is often adjusted by manual extrusion, and because it is not easy to fix, the arc-shaped beam formwork cannot accurately generate the required arc-shaped beams radian

Embodiment 1

[0023] An adjustable connecting device for arc beam template, such as figure 1 , figure 2 As shown, it includes a threaded sleeve 7 provided with internal threads, a screw rod 8 provided with external threads, a smooth sleeve 9, and a guide rod 10. A connecting rod 13 is provided between the threaded sleeve 7 and the smooth sleeve 9 A limit rod 14 is provided between the screw 8 and the guide rod 10, and one end of the limit rod 14 is fixedly connected to the guide rod 10, and the other end is provided with a limit ring 15. The screw 8 is provided with a flange 16, and the screw The rod 8 passes through the limit ring 15 and is threadedly connected with the threaded sleeve 7.

[0024] During construction, the construction personnel install the adjustable connecting device of the present invention on the arc-shaped beam template so that the connecting rod 13 and the limit rod 14 are respectively connected to the two ends of the arc-shaped beam template, and the constructor rotate...

Embodiment 2

[0027] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 , figure 2 As shown, further, the screw 8 is provided with an operating part 18, and the operating part 18 is located on the extension line of the tail of the screw 8. The operating part 18 can be set in various shapes that are convenient to use according to the needs of use. The operator rotates the operating part 18 so that the screw 8 rotates. If the operating part 18 is connected with the motor, the automatic operation of the present invention can also be realized, so that the construction personnel can save labor during construction.

Embodiment 3

[0029] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 , figure 2 As shown, further, the smooth sleeve 9 is provided with a support 11, the guide rod 10 is provided with a b support 12, and both the a support 11 and the b support 12 are provided with connecting holes. The present invention is used to connect the two ends of the arc-shaped beam template. Corresponding connecting pieces need to be provided on the smooth sleeve 9 and the guide rod 10 respectively. A support 11 is provided on the smooth sleeve 9 and a support b is provided on the guide rod 10. The base 12, and the a support 11 and the b support 12 are provided with connecting holes, which can facilitate the manufacturer to set a connecting piece that matches the connecting hole according to the shape of the template.

Abstract

The invention discloses an adjustable connection device for an arc beam formwork. The adjustable connection device comprises a threaded sleeve with an internal thread, a screw rod with an external thread, a smooth sleeve and a guide rod, wherein a connecting rod is arranged between the threaded sleeve and the smooth sleeve; a limiting rod is arranged between the screw rod and the guide rod; one end of the limiting rod is fixedly connected with the guide rod, and a limiting ring is arranged at the other end; a flange is arranged on the screw rod; the screw rod passes the limiting ring and is in threaded connection with the threaded sleeve; an operation part is arranged on the screw rod; a support a is arranged on the smooth sleeve; a support b is arranged on the guide rod; and a connection hole is formed on the support a and the support b respectively. The adjustable connection device disclosed by the invention has the following beneficial effects: adjustable radian of the arc beam formwork can be realized, and the radian is kept stable in the construction process; the physical strength of constructors can be saved so that the construction process is simple and convenient; and the structure is stable, and the service life is long.

Description

Technical field [0001] The invention relates to the technical field of construction formwork accessories, in particular to an adjustable connecting device for arc beam formwork. Background technique [0002] In the construction of home decoration projects, some arched or curved concrete beams are often encountered. Especially in modern home decoration, many residents like to choose European style decoration, and European style decoration design cannot be separated from arched or curved shapes. For the concrete lintels of the doors and windows of the structure, if the construction method of cast-in-place concrete is adopted in these parts, the formwork erection or dismantling will cause great interference to the construction, and the construction period is long and the cost is large. Usually, the decoration construction worker cuts the wood board into long strips, and roughly bends it into an arc shape along the required arc surface, and then directly pours concrete on its upper p...
