Abstract

A wall verticality checking ruler is provided with a side ruler (2) and a scale (3) on the two ends of a main ruler (1). The axes of the side ruler (2) and the scale (3) are in parallel with each other and are perpendicular to that of the main ruler (1), and the end faces (6) (7) of the side ruler (2) and the scale (3) are in parallel with the axis of the main ruler (1); the scale (3) capable of making axial displacement has a zero graduation arranged in the center of all graduations, and the length of the extension end of the scale (3) is equal to that of the elongation end of the side ruler (2) when the zero graduation is aligned with the side face of the main ruler (1). The main ruler (1) is also provided with a horizontal tube (4) and a knob (5) matched with the scale (3). When the utility model is used, the main ruler (1) is pulled straight, the scale (3) extends out with the zero graduation regulated to be aligned with the side face of the main ruler (1), then the end face (6) of the side ruler (2) and the end face (7) of the scale (3) adhere to the wall surface, the knob is regulated to make an air bubble of horizontal tube (4) be placed in the middle, and at that time the indication on the scale (3) is just the deviation value of the wall verticality.

Description

A kind of body of wall verticality verification chi

One, technical field

The utility model relates to a kind of survey instrument, specifically a kind of body of wall verticality verification chi.

Two, background technology

Verticality is an important technology index that guarantees body of wall safety.To the body of wall more than the 2m, have a down dip on it and depart from vertical plane and must not surpass 5mm, body of wall is higher, and this numerical value is littler.At present mainly use guiding ruler (also claiming the tail chi) to detect, guiding ruler is marked with a perpendicular line and a sash weight is arranged, and guiding ruler is adjacent to metope, looks the degree that the overlaps verification body of wall verticality of sash weight and vertical line.Guiding ruler is simple in structure, but the identical single pendulum of sash weight, and poor stability under the particularly outdoor situation that wind arranged, influences precision.

Three, summary of the invention

The verification chi that the utility model provides is intended to monitoring and detect in the verticality of the body of wall of building or completed, and technical matters to be solved is that operational stability is good, the accuracy of detection height.

The technical solution of the utility model comprises that one can fold or flexible main scale 1, upper/lower terminal at main scale 1 is respectively arranged with side chi 2 and rule 3, the axis of side chi 2 and rule 3 is parallel to each other, and with the axis normal of main scale 1, the parallel axes of the end face 6 of side chi 2 and end face of rule 37 and main scale 1; Rule 3 is left and right displacement axially, the central authorities that reading occupies whole scales for the scale (being zero graduation) of " 0 " on it, displacement scale, make the side in alignment (promptly concordant) of zero graduation and main scale 1, at this moment, the end face 6 of its end face 7 and side chi 2 to the distance of main scale 1 this side equates that just the axial line distance to main scale 1 equates; In other words, the equal in length of the length of rule 3 external parts and side chi 2 external parts; The knob 5 that on main scale 1, also is provided with horizontal tube 4 and matches with rule 3.As shown in Figure 1.

For being convenient for carrying and preventing that side chi 2 is damaged, side chi 2 can be movable with being connected of main scale 1, such as going in the main scale 1 by flexible (displacement) or rotating bezel.As shown in phantom in Figure 1.

The displacement of rule 3 realizes by knob 5, when being rotated down such as knob 5, and protruding (to left dislocation), instead then (displacement to the right) in the retraction main scale 1.As shown in Figure 2.

The utility model is to use like this.Folding main scale 1 is stretching, and the side chi 2 on screwing out makes it vertical with main scale 1, and rotary knob 5 stretches out rule 3, and adjustment makes zero graduation align with main scale 1 side.After carrying out above-mentioned preparation, the end face 6 of side chi 2 and the end face 7 of rule 3 are clinged on the wall plane, bubble in the eye-level pipe 4, and adjusting knob 5, make the bubble of horizontal tube 4 placed in the middle, the reading that indicate on the rule 3 this moment is the vertical up and down variation of body of wall.

The utility model is simple in structure, easy to process, and good stability not only can detect the body of wall that has completed, also can be to monitoring at the body of wall of building, and the precision height.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.The zero graduation of rule 3 is concordant with main scale 1 side among the figure, and dotted line schematic side chi 2 is gone in the main scale 1 by rotating bezel.

Fig. 2 is that rule 3 cooperates synoptic diagram with knob 5.

Five, embodiment

In conjunction with Fig. 1 Fig. 2, non-limiting examples is described below:

Get hard, dry, on-deformable wood materials processing main scale 1, middle with 8 connections of table-hinges chain, main scale 1 can be folded.

" L " type side chi 2 is set, the end face 6 on the side chi 2 and the parallel axes of main scale 1 in main scale 1 upper end.Between the side of this end face and main scale 1 apart from 4cm, i.e. the long 4cm of external part.

The cross section that is provided with rule 3 that can displacement in the lower end of main scale 1 and matches with rule 3 is the knob 5 of dodecagon, rule 3 cross sections are half dodecagon, side on the plane indicates scale, zero graduation is positioned at the mid point of whole scales, zero graduation each side has the 4cm scale, be zero graduation when concordant with main scale 1 side, the long 4cm of its external part.

Near being positioned at rule 3 on the main scale 1, horizontal tube 4 is set.

Claims

1. body of wall verticality verification chi, it is characterized in that: the upper/lower terminal at a main scale (1) that can fold or stretch is respectively arranged with side chi (2) and rule (3), the axis of side chi (2) and rule (3) is parallel to each other, and with the axis normal of main scale (1), the parallel axes of the end face (6) of side chi (2) and the end face (7) of rule (3) and main scale (1); Rule (3) is left and right displacement axially, and zero graduation occupies the central authorities of whole scales on it, and the end face (6) of its end face (7) and side chi (2) to the distance of this side of main scale (1) equates when the zero graduation and the side of main scale (1) are concordant; The knob (5) that on main scale (1), also is provided with horizontal tube (4) and matches with rule (3).

2. verification chi according to claim 1 is characterized in that: side chi (2) can rotate or flexible the embedding in the main scale (1).
