Problems solved by technology

[0002] In the construction process of the construction site, it is often necessary to carry out level measurement, and in the process of level measurement, the error of level measurement is often caused by environmental factors or installation factors, and now the level calibration often uses a heavy hammer, but the heavy hammer It often takes up a lot of space in the vertical direction, which is not conducive to the measurement of surface level. In addition, it takes a long time to calibrate, is greatly affected by wind or other factors, and has a large volume
Existing level measuring devices often measure the level of the surface of the structure, and it is not easy to measure the points. If there are concave and convex parts between the measurement points, the accuracy of the measurement will often be significantly reduced.

Embodiment 1

[0027] Such as figure 1 and 2 As shown, the present invention discloses a cross-shaped fixed-point level detector for building construction, comprising a cross-shaped pipe body 1, the four ends of the pipe body 1 are sealed, and transparent liquid is housed in the pipe body 1 and placed on the pipe body 1 A bubble 3 for judging the level is formed inside; the lower part of the tube body 1 is connected with a cross-shaped frame body, and the four arms of the frame body are respectively connected with vertical alignment rods 8, and the alignment rods 8 can be positioned along each side of the frame body. The arm slides and can be lifted vertically, and the lower tip of the alignment rod 8 is used to align the point to be measured. The tube body is made of transparent material.

[0028] The alignment bar 8 is connected to the cross-shaped frame body by the alignment mechanism. The alignment mechanism includes a slide frame 6 and a lifter 7. The slide frame 6 is slidably connect...

Embodiment 2

[0034] The liquid in Example 1 is composed of the following parts by weight: 90-120 parts of distilled water, 0.4-0.6 parts of sodium chloride, 0.4-0.9 parts of activated carbon, 0.1-0.2 parts of methyl p-hydroxybenzoate, 0.2-0.3 parts of Chlorobutanol, 0.3-0.7 part of sodium hypochlorite, 0.7-0.8 part of pigment.

Embodiment 3

[0036] In the horizontal detector structure in embodiment 1, the guide frame at the lower edge of the inverted V-shaped guide groove has an inward turn-up, and the guide frame is made of the following materials in parts by weight: 0.1-0.3 parts of tungsten, 3 -5 parts of boron carbide, 1.3-1.5 parts of boron fiber, 0.4-0.6 parts of molybdenum disilicide, 0.4-0.8 parts of silicon carbide, 0.5-0.9 parts of magnesium oxide, 0.1-0.7 parts of silicone rubber, 5-9 parts of water glass, 20 -25 parts of nano-silica, 5-7 parts of sodium fluorosilicate, 4-7 parts of barite; the tube body 1 includes a glass layer, a mesh-like braided layer, and a transparent plastic layer from the inside and outside; the braided layer is composed of The following materials are woven by weight: 11-15 parts of stainless steel fiber, 4-7 parts of silk, 15-16 parts of nylon fiber, 1-7 parts of copper fiber, 2-4 parts of silver fiber, and 16-20 parts of glass fiber. The guide frame of this composition has the c...

Abstract

The invention relates to the field of building construction and in particular relates to a cross-shaped fixed-point level detector for building construction. The cross-shaped fixed-point level detector comprises a cross-shaped pipe body; four end parts of the pipe body are sealed; the pipe body is internally filled with transparent liquid and air bubbles for judging the level are formed in the pipe body; a lower part of the pipe body is connected with a cross-shaped frame body; four arms of the frame body are connected with vertical alignment rods respectively; the alignment rods can slide along each arm of the frame body and can vertically hoist; tips of lower parts of the alignment rods are used for aligning with a point to be detected. According to the structure, the levelness of two point positions in the building construction is judged, so that the accuracy of measurement is improved and errors of surface measurement are reduced; a phenomenon that the inaccuracy of the level judgment of the measured point is caused by the fact that a plane where the measured point exists is uneven is prevented in a measurement process; level measurement of a conventional plane is converted into level measurement of the point, a measurement manner is improved and the error rate is reduced.
