Abstract

The utility model relates to a multi-purpose surveyor's staff for construction use. The utility model can replace a ruler, an angle square and a level bar of the construction and the similar construction can be replaced. An open cavity box space is arranged at the middle part of the square staff body of the multi-purpose surveyor's staff, and an indicating needle which is freely rotated around a rotary shaft is penetrated and hung through the rotary shaft which is supported on the staff body arranged in the cavity box space. A hemisphere hang bead is arranged on the indicating needle, and circular angle reticles which use the shaft center of the rotary shaft as the center of a circle and is matched with the indicating needle are arranged on a translucent staff body wall corresponding to the space of the cavity box. Length reticles are respectively arranged on the surface edge of corresponding staff body.

Description

The building multipurpose ruler

The utility model relates to the building multipurpose ruler that a kind of building operation is used, and also can be used as the instrument of hydropower installation, highway, bridge construction, chimney, blast furnace construction, the construction of groove canal, replaces ruler, angle square, surveyor's staff etc.

At present, in building and the similar building masonry construction, all adopt single ruler, angle square and surveyor's staff, also need the messenger wire unwrapping wire, it is very inconvenient to construct, and error is also big.

The purpose of this utility model just is: design a kind of building multipurpose ruler, replace ruler, angle square, surveyor's staff, make construction more convenient.

The utility model achieves the goal like this: in the design of the middle part of rectangle chi body an atrium box space is arranged, in this box space, chamber by be supported on turning axle on the chi body wear hang with one can be around its pointer that rotates freely, be equiped with the hemisphere hanging bead on the pointer, axle center with turning axle is arranged is the circular angle groove center of circle and that match with pointer in design on corresponding to the transparent ruler body wall at position, box space, chamber, and design has the length groove respectively on the edge of this corresponding chi surface.

The utility model also can be realized purpose like this, is equiped with cover plate on the opening in box space, chamber, and its outside surface and chi body respective surfaces are in the same plane.

Keep the vertical fixing assembling between the respective surfaces of turning axle of the present utility model and supporting chi body.

Owing to the utlity model has said structure design, the function of ruler, angle square, surveyor's staff organically is combined as a whole, only instrument is constructed in building operation and the similar construction with one, the many usefulness of a chi, and do not need messenger wire, unwrapping wire, the construction use is very convenient.Be applicable to that very wood ash stone brickwork uses.Under the situation that improves its manufacturing accuracy, also can be used in plant equipment processing and the installation.

Further specified below in conjunction with drawings and Examples, but be not limited only to this.

Fig. 1 is a front elevational schematic of the present utility model;

Fig. 2 is a schematic top plan view of the present utility model;

Fig. 3 is an A-A cross-sectional schematic of the present utility model;

Fig. 4 is a three-dimensional reference view of the present utility model.

As shown in FIG., this multipurpose ruler is the chi body 2 of a rectangle, for example, generally makes rectangular flat, and long 40 centimetres, thick is 2 centimetres, and wide is 8 centimetres, long and wide seamed edge form right angle chi.And can be according to actual needs, selected other sizes are made.Design has an atrium box space 9 at chi body 2 middle parts, in this space 9 by be supported on a turning axle 3 on the chi body 2 wear hang one can be around its pointer that rotates freely 4, the length of pointer 4, thickness and space 9 should adapt, turning axle 3 keeps vertical with the respective surfaces of supporting chi body 2, and two ends fixedly are assemblied on the chi body 2.After having assembled,, also can adopt the fixing assembling of helicitic texture mode with the seccotine cementation.It among the figure gluing design.Design has hemisphere hanging bead 5 on the pointer 4, in order to increase pointer 4 sagging weight.Axle center with turning axle 3 is arranged is circular angle groove 6 center of circle and that match with pointer 4 in design on corresponding to transparent ruler body 2 walls at 9 positions, box space, chamber, during use, angle of inclination difference along with construction surface, pointer 4 is around turning axle 3 rotation respective angles, and pointer 4 indicated angles are the angles that tilt.Design has length groove 1 respectively on the edge of this corresponding chi surface (i.e. design has the chi surface of angle groove 6), uses as ruler.In order to prevent dust, water or windage measuring accuracy, on the opening in box space, chamber 9, be equiped with cover plate 7, the respective surfaces of the outside surface of cover plate 7 and chi body 2 is in the same plane.Clear for drawing, accompanying drawing inside still adopts dotted line to represent inner structure.

During manufacturing, the general whole transparent material that adopts is made as organic glass.The chi body region place that also can only be carved with angle groove 6 at 9 positions, box space, chamber adopts transparent material, so that cooperates observation reading angular number with pointer 4.In addition, each surface of chi body 2 processes straight as far as possible, and keeps vertical mutually as far as possible, and turning axle 3 diameters are as far as possible little, and is more accurate when keeping this multipurpose ruler to measure.
