Description

Technical Field

[0001] The utility model relates to the field of verticality detection of walls and columns, in particular to a verticality deviation angle detection device for building construction. Background Art

[0002] In the field of building construction, it is crucial to ensure the verticality of walls and columns. Verticality not only affects the appearance quality of the building, but also affects the stability and service life of the structure. Therefore, accurate detection of the verticality of finished walls and columns is an important part of construction quality control.

[0003] A tool for quickly measuring the verticality of a wall or a column is provided in the prior art. The tool comprises a double-layer rectangular outer cover, a colored liquid, a high-carbon steel vertical pointer with a plumb bob, and a horizontal height difference scale. An inverted protractor and a vertical semicircular vertical deviation scale are engraved on the inner side of a transparent box formed by the double-layer organic glass outer cover, and the box is half filled with liquid. When detecting the verticality of a wall or a column, one side of the instrument is placed close to the measuring surface, and the verticality deviation angle a of the wall can be obtained from the angle of the liquid surface displayed on the protractor on the surface of the inner box of the instrument.

[0004] However, when using the above tools for measurement, because the outer cover is a rectangular structure, if the inclination angle of the measuring surface is large, the liquid level will rise and fall significantly. Since the protractor is fixed, the vertex of the verticality deviation angle a cannot coincide with the center of the protractor, and at the same time, one side of the verticality deviation angle a cannot coincide with the corresponding scale line of the protractor, which leads to inaccurate measurement or inability to measure. Utility Model Content

[0005] In order to solve the technical problem that the protractor cannot be guaranteed to measure accurately in the above-mentioned prior art, the utility model provides a verticality deviation angle detection device for construction, which can adjust the position of the protractor to ensure measurement accuracy.

[0006] The utility model adopts the following technical solution to solve the above technical problems: a verticality deviation angle detection device for construction, comprising a transparent shell, a liquid is arranged in the transparent shell, a slot is vertically arranged on one side of the transparent shell, a protractor is movably arranged in the slot, the 90° scale line of the protractor can be flush with the liquid surface of the liquid in a horizontal state, and the zero scale line of the protractor is flush with the edge of the cavity of the transparent shell close to the measuring surface.

[0007] The utility model can adjust the position of the protractor according to the change of the liquid level during measurement by movably arranging the protractor on the transparent housing, thereby avoiding measurement errors caused by the rise and fall of the liquid level and ensuring the measurement accuracy.

[0008] Furthermore, the protractor is provided with an insert block, the insert block is arranged parallel to the 0° scale line of the protractor, and the insert block can move along the slot.

[0009] Furthermore, the length of the protractor in the vertical direction is L1, the length of the transparent shell in the vertical direction is L2, the height of the liquid is L3, L1+5mm<L2 and 0.5*L1≤L3.

[0010] The utility model can avoid the protractor interfering with the ground when used at the base of a wall or the base of a column, thereby preventing the verticality at the base of a wall or the base of a column from being measured by setting L1+5mm<L2 and 0.5*L1≤L3.

[0011] Furthermore, the slot is a dovetail slot, and the insert block matches the slot in shape. By using the dovetail slot, the contact area with the insert block is increased to avoid movement under the action of its own gravity after adjustment.

[0012] Furthermore, the liquid is a colored liquid. The use of colored liquid enhances recognition.

[0013] Furthermore, a wear-resistant layer is provided on one side of the transparent shell close to the measuring surface, so as to reduce the wear of the measuring surface on the transparent shell.

[0014] It can be seen from the above technical solutions that the utility model has the following advantages:

[0015] The utility model provides a verticality deviation angle detection device for building construction. By movably arranging a protractor on a transparent shell, the position of the protractor can be adjusted according to the change of liquid level height during measurement, so as to avoid measurement errors caused by liquid level rise and fall and ensure measurement accuracy; by setting L1+5mm<L2 and 0.5*L1≤L3, it can avoid that the protractor interferes with the ground when used at the root of a wall or the foot of a column, and the verticality at the root of the wall or the foot of a column cannot be measured; by using a dovetail groove to increase the contact area with the plug block, it can avoid movement under the action of its own gravity after adjustment; by using colored liquid, the recognition is enhanced; and by arranging a wear-resistant layer, the wear of the transparent shell on the measuring surface is reduced.

[0022] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] like Figure 1 As shown, this specific embodiment provides a verticality deviation angle detection device for construction, including a transparent shell 1 and a protractor 3; liquid 2 is arranged in the transparent shell 1, a slot 5 is vertically arranged on one side of the transparent shell 1, and the protractor 3 is movably arranged in the slot 5, the 90° scale line of the protractor 3 can be flush with the liquid surface of the liquid 2 in the horizontal state, and the zero scale line of the protractor 3 is flush with the edge of the cavity of the transparent shell close to the measuring surface 7.

[0024] In this specific embodiment, the protractor 3 is movably arranged on the transparent shell 1, so that the position of the protractor 3 can be adjusted according to the change of the liquid level before measurement, so as to avoid that the zero line and the center point of the protractor 3 cannot coincide with the vertex and one side of the verticality deviation angle a, thereby avoiding the influence of the liquid level rise and fall changes to ensure the measurement accuracy.

[0025] like Figure 2 and Figure 3 As shown, an insert block 4 is provided on the protractor 3, and the insert block 4 can move along the slot 5. The insert block 4 is arranged parallel to the 0° scale line of the protractor 3. Preferably, the slot 5 is a dovetail slot, and the insert block 4 matches the shape of the slot 5. By using the dovetail slot, the contact area with the insert block 4 is increased to avoid movement under the action of its own gravity after adjustment.

[0026] In the prior art, the measurement of verticality often takes multiple measurement values, and sometimes it is necessary to detect the verticality at the foot of a column or the root of a wall. In order to avoid the protractor 3 from interfering with the ground, in this specific embodiment, the length of the protractor 3 in the vertical direction is L1, the length of the transparent shell 1 in the vertical direction is L2, the height of the liquid 2 is L3, L1+5mm<L2 and 0.5*L1≤L3, so as to ensure that after adjustment, the sharp corner of the protractor 3 is always a certain distance away from the ground and will not interfere with the ground. In this specific embodiment, L3 is 0.5*L2.

[0027] Preferably, the liquid level contains colored liquid 2. The use of colored liquid 2 enhances the recognition. In the present specific embodiment, the liquid 2 is blue.

[0028] Preferably, a wear-resistant layer 6 is provided on one side of the transparent shell 1 close to the measuring surface 7 to reduce the wear of the measuring surface 7 on the transparent shell 1 . In this specific embodiment, the wear-resistant layer 6 is made of rubber material.

[0029] Since the protractor 3 in this specific embodiment is movably arranged, it is not necessary to require that the height of the liquid 2 is half of the cavity of the transparent shell 1 .

[0030] The process of the vertical deviation angle detection device for building construction is as follows:

[0031] First, the wear-resistant layer of the transparent shell 1 is closely attached to the measuring surface 7 of the wall or cylinder, and then the protractor 3 is removed and the position of the protractor 3 is adjusted to ensure that the center point is located on the straight line where the liquid surface is located. The vertical deviation angle a generated by the 90° scale line and the liquid surface is observed and read, and the vertical deviation angle a of the wall or cylinder is obtained.

[0032] From the above specific implementations, it can be seen that the utility model has the following beneficial effects:

[0033] 1. By movably setting the protractor 3 on the transparent housing 1, the position of the protractor 3 can be adjusted according to the change of the liquid level before measurement, thereby avoiding measurement errors caused by the rise and fall of the liquid level and ensuring measurement accuracy;

[0034] 2. By setting L1+5mm<L2 and 0.5*L1≤L3, it is possible to avoid the protractor 3 interfering with the ground when used at the base of a wall or a column, and failing to measure the verticality at the base of a wall or a column;

[0035] 3. By using the dovetail groove to increase the contact area with the insert 4, it is prevented from moving under its own gravity after adjustment;

[0036] 4. Enhanced recognition by using colored liquid 2;

[0037] 5. The wear of the transparent housing 1 on the measuring surface is reduced by providing a wear-resistant layer.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
