Description

Template verticality detection device and detection method thereof

technical field

The invention relates to a verticality detection device and a detection method thereof, in particular to a template verticality detection device and a detection method thereof.

Background technique

In the construction of domestic cast-in-place concrete structures, most of the vertical member formwork systems use reinforcement methods such as bamboo plywood, multi-layer boards, wooden squares, tension bolt rods, steel pipes, and fasteners. After the formwork support is completed, the verticality test of the formwork is carried out. Due to the barriers generated by the formwork reinforcement and the secondary corrugation (usually wooden) and the main corrugation (generally steel pipe) in the support system, the general verticality detection ruler cannot accurately measure the formwork. In the past, the verticality of the formwork was tested by using a hanging wire and a steel tape. The detection is cumbersome, time-consuming and labor-intensive, and the quality of the detection results is not high. Usually, two people are required to cooperate to complete the detection. Two people can test up to 20 ordinary residential shear wall formworks a day, and the quality of the test results is not high.

The template verticality detection device also includes a hanging wire 4, the hanging wire 4 is fastened on the upper leg 2 through the nail 5, the bottom of the hanging wire 4 is connected to the wire pendant 41, and the length of the hanging wire 4 is greater than the length of the support rod 1. Referring to shown in Fig. 2, lower leg 3 is provided with scale 31, and the position scale of suspension wire 4 vertical lower leg 3 is set to 0, and scale 31 is respectively established the scale of 10cm with 0 as the center, and the smallest scale unit is millimeter.

The upper leg 2 and the lower leg 3 can be a retractable structure. As a preferred embodiment of the present invention, the upper leg 2 and the lower leg 3 are set as screw rods, and corresponding screw holes are opened at the corresponding positions of the support rod 1, and the screw holes are realized through thread fit. The telescopic adjustment of the upper leg 2 and the lower leg 3 must ensure that the exposed lengths of the upper leg 2 and the lower leg 3 are equal on the side of the support rod 1 that is the side where the suspension wire 4 is installed.

The use of this detection device will be described below.

Please refer to Fig. 3, in this embodiment, the detection device support rod 1, upper leg 2 and lower leg 3 form a U-shaped frame, wherein: the support rod 1 is a square steel pipe of 50*20*3*2000mm, and the upper Leg 2 is made of 20*20*3*350mm square steel pipe, lower leg 3 is made of 20*20*3*350mm square steel pipe, upper leg 2 and lower leg 3 are perpendicular to the support rod at 90 degrees and welded to the two At the end, the suspension wire 4 is fixed on the upper leg 2 at a distance of 10 cm from the inner side of the support rod. The part length of the suspension wire 4 that exceeds the lower leg 3 is 10 cm, and the suspension wire is selected from common specifications. The length of the upper and lower legs is 350mm, the length of the scale 31 is 200mm, the remaining 150mm of the lower leg 3 is 150mm except the scale, and the thickness of the general main flute plus the second flute is less than 150mm, so this device effectively solves the problem of the main flute and the second flute.

The template 6 to be tested is fastened on the wooden square 7 through the screw rod 9 and the steel pipe 8, holes are opened on the wooden square 7 corresponding to the positions of the upper leg 2 and the lower leg 3, and the verticality detection device is inserted on the wooden square 7, and the wire The pendant 41 makes the suspension wire 4 hang down naturally. Because the length of the suspension wire 4 exceeds the lower leg 3, the scale corresponding to the suspension wire 4 can be easily read. In this embodiment, the template 6 is in a vertical state, so the suspension wire 4 hangs down naturally. The corresponding scale is 0.

In this embodiment, the formwork 6 is also fastened on the wooden side 7 by the screw rod 9 and the steel pipe 8, holes are opened on the wooden side 7 corresponding to the positions of the upper leg 2 and the lower leg 3, and the verticality detection device is inserted into the wooden side. On the square 7, the hanging wire 4 hangs down naturally by the hanging wire 41, because the length of the hanging wire 4 exceeds the lower leg 3, so the corresponding scale of the hanging wire 4 can be easily read. In this embodiment, the template 6 is in an inclined state, so it can be read that the perpendicularity deviation of the template 6 is X. And the actual deviation of the template 6 at the detection part of the detection device is Y, and the acute angles corresponding to the two deviations in the respective right triangles are a, so it is drawn that tan(a)=X÷2000, Sin(a)=Y÷ In 2000, a=arctan(X÷2000)=acrsin(Y÷2000) was launched. When X=0, Y=0, when X=100mm, Y=99.88mm. |X)Y|=0.12mm. Therefore, when the reading is 100mm, the error with the actual value is 0.12mm. Meet the requirements of the current specification for template detection. When the actual deviation of the verticality of the template exceeds 100mm, the human eye can see its inclination, so there is no need to expand the detection range.
