Description

A verticality tester for concrete formwork with a windshield

technical field

The invention belongs to the civil engineering construction industry, and relates to a device for detecting the verticality of a civil engineering formwork, in particular to a verticality detector for a concrete formwork provided with a windshield.

Background technique

Before pouring concrete in civil construction projects, the construction unit needs to check the verticality of the shear wall, column formwork, and the verticality and straightness of the beam formwork. The existing method uses a theodolite to check, but it requires a positioning line as a basis. If there is no condition, a hanging plumb will be used. After the plumb is stable, use a steel tape to measure the distance from the upper, middle, and lower parts of the column and board wall formwork to the vertical line. Distance, so as to calculate the flatness error of the template. If the three dimensions are consistent, it means that the template is parallel to the vertical line, that is, vertical. If they are not consistent, the template must be adjusted to finally achieve straightness and verticality. The existing method of measurement is relatively complicated, and this operation usually requires two to three people to participate, and it is necessary to work on the relatively dangerous scaffolding outer frame, which is not only inefficient, but also quite dangerous.

Contents of the invention

The technical problem to be solved by the present invention is to provide a concrete formwork verticality detector equipped with a windshield, which solves the problems existing in the current detection of concrete formwork verticality in the civil engineering industry, and uses a simple verticality detector to reduce the number of workers The operating procedures in the construction process, improve construction efficiency and project quality, and reduce the risk of operation.

The technical solution adopted by the present invention to solve the above technical problems is: a concrete formwork verticality detector provided with a windshield, including a vertical pole, and a verticality detector for detecting the accuracy of the concrete formwork verticality detector is provided in the middle of the vertical pole. For the circular level, the two ends of the vertical pole are fixedly connected with the upper support point and the lower support point which are parallel to each other. A laser emitter is suspended by a rope under the upper support point. Cover, the lower part is equipped with a scale that cooperates with the laser transmitter to read the verticality of the template.

The length of the pole of the present invention can be telescopically adjusted.

A handle is provided on the vertical rod below the circular level.

The upper support point and the lower support point of the present invention are two aluminum alloy tubes.

The scale is set to increase from 0 to both ends.

The beneficial effects of the present invention are: the verticality detector of the concrete formwork that the present invention designs is provided with windshield through the method for reading the verticality of formwork by laser emitter and the lower part with scale, has overcome traditional detection method inefficiency, Dangerous disadvantages, can significantly improve work efficiency, and with precision, can significantly improve the problem of verticality out of tolerance of shear walls and columns, significantly improve the quality of the project, and can speed up the construction speed, save the construction period, save labor, Reduce the construction cost; at the same time, because the windshield is installed at the lower end of the laser transmitter, it can overcome the disadvantages of being seriously affected by the weather, and the detection can also be carried out in windy weather without affecting the detection results and reducing losses.

Detailed ways

As shown in the figure, a concrete formwork verticality tester provided with a windshield includes a vertical pole 1, and a circular level 2 for testing the accuracy of the concrete formwork verticality tester is provided in the middle of the vertical pole 1. The two ends of the rod 1 are respectively fixedly connected with the upper support point 6 and the lower support point 5 parallel to each other, and a laser emitter 7 is suspended by a rope under the upper support point 6, and a windproof device is also set outside the laser emitter 7. The cover 8 is provided with a scale 4 that cooperates with the laser emitter 7 to read the verticality of the template on the lower support point 5 .

When the bubble of the circular level is in the center, the line connecting the ends of the lower support point 5 and the upper support point 6 is in a vertical state. At this time, the reading of the laser transmitter 7 on the scale 4 should be 0, so that the accuracy of the detector can be detected. Spend.

The length of the pole 1 is telescopically adjustable.

A handle 3 is provided on the pole 1 below the circular level 2 .

The upper support point 6 and the lower support point 5 are two aluminum alloy tubes.

When using the concrete formwork verticality detector provided with a windshield according to the present invention, hold the handle 3, adjust the height of a suitable vertical pole 1, and place the upper part 6 and the lower part 5 on the upper part and the lower part of the formwork respectively , Observe the scale number corresponding to the signal of the vertical ray projected by the laser transmitter 7 on the lower fixed node 5 to calculate the verticality of the template.

The template verticality detector can not only be used to detect the verticality of the template, but also can be used in the detection of the verticality of the wall surface, the cylinder surface and the flatness of the plastering, and the promotion prospect is good.
