Description

A kind of scriber

Technical field

The utility model belongs to repairing technology of concrete crack field, is specifically related to a kind of scriber.

Background technology

Plain concrete panel is in construction and the impact that is subject to many complicated factors in service, inevitably can form crack, the repairing in crack is according to the method for patent ZL 200910066375.1, need to grind along irregular cracks the groove of width 5-12cm, want the slot grinding first will be at the equidistant graticule in both sides, crack, crack be erose, on-the-spotly rules with spline, speed is very slow, and efficiency is very low.Be badly in need of the special scriber of research and development and meet construction requirement.

Utility model content

The purpose of this utility model be to provide a kind of can be rapidly and accurately at the scriber of the equidistant line in both sides, crack.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of scriber, comprise handle, described handle front end bifurcated is two terminations, two terminations are all provided with bow pen clips, hold-down nut from front to back successively, bow pen clips is located at handle inner side, and hold-down nut is located at handle below, is equipped with line-spacing adjusting screw between two hold-down nuts, line-spacing adjusting screw middle part is provided with pilot pin, on line-spacing adjusting screw, is respectively provided with a traveling nut in two hold-down nut both sides.

Further, on described line-spacing adjusting screw, to be provided with guide pin (be that described line-spacing adjusting screw is provided with the guide pin corresponding with pilot pin to rearward position corresponding to pilot pin, pilot pin and guide pin are located at respectively the forward and backward position of line-spacing adjusting screw), guide pin is 0 ° of (parallel)-50 ° with the angle between pilot pin, and guide pin and pilot pin lowermost end air line distance are 0.5-3cm.Guide pin can be used as with reference to revising in time direction of travel in the time of line.

Preferably, guide pin and pilot pin are preferably two iron nails.

Preferably, described bow pen clips is preferably pipe collar.

Further, pipe collar diameter is 5-30mm, and pipe collar can regulate diameter, is used for clamping the bow pen of variety classes and model.

Preferably, described hold-down nut is hex nut, and is located at the traveling nut of hold-down nut both sides: one is hex nut, is located at hold-down nut inner side; Another is wing nut (convenient construction personnel rotation, to regulate line-spacing), is located at hold-down nut outside.

Preferably, line-spacing adjusting screw is common screw, diameter 2-15mm, length 6-20cm.

Preferably, described handle can be any shape of being convenient to holding operation, but is preferably U-shaped or V-arrangement handle (handle front portion is opened larger than rear portion).

Further, described handle is served as reasons, and three sections of front U-shaped sections, smooth curved section, rear U-shaped section form and front U-shaped section is opened larger U-shaped handle than rear U-shaped section.

Further again, described handle is bent and is formed by a metal bar, and metal bar diameter is 2-15mm, and the length of front U-shaped section is 2-15cm, and the length of rear U-shaped section is 3-20cm.

The beneficial effects of the utility model: according to engineering construction needs, can regulate traveling nut to determine two distances between bow pen before line, guarantee that two bow pens are identical apart from the distance between center locating pin simultaneously; By regulating the size of bow pen clips can use the bow pen of different model; When line, center locating pin advances along the direction of irregular cracks, and guide pin can be used as with reference to revising in time direction of travel in the time of line, can mark and equidistant two graticules in crack; The utility model is reasonable in design, simple in structure, easy to use, can mark rapidly and accurately two graticules of line centered by crack along both sides, crack, a difficult problem of having rule along irregular cracks while having solved mending concrete crack.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

The specific embodiment

As shown in Figure 1, a kind of scriber, comprise U-shaped handle 6, handle 6 front end bifurcateds are two terminations, two terminations are all provided with bow pen clips 1 from front to back successively, hold-down nut 4, bow pen clips 1 is welded on handle 6 inner sides, hold-down nut 4 is welded on handle 6 belows, between two hold-down nuts 4, be equipped with line-spacing adjusting screw 2, line-spacing adjusting screw 2 middle parts are vertically welded with pilot pin 7, on line-spacing adjusting screw 2, rearward position corresponding to pilot pin 7 is vertically welded with guide pin 5, guide pin 5 is 0 ° (parallel) with the angle between pilot pin 7, on line-spacing adjusting screw 2, be respectively provided with a traveling nut 3 in two hold-down nut 4 both sides.Wherein, described handle 6 is bent and is formed by a metal bar, by three sections of front U-shaped sections, smooth curved section, rear U-shaped section form and front U-shaped section to open greatly than rear U-shaped section (be that two metal bars of handle 6 front end are distant, then smooth curved diminishes two distances between rod), metal bar diameter is 5mm, and front U-shaped segment length is 10cm, plays a supporting role, then the length of U-shaped section is 20cm, convenient operation; Guide pin 5 is two iron nails with pilot pin 7, and two iron nail lowermost end air line distances are 0.6cm; Described bow pen clips 1 is pipe collar, and pipe collar diameter is 16mm, and pipe collar can regulate diameter, is used for clamping the bow pen of variety classes and model, and wherein bow pen can be the pen that any kind can be rule on concrete; Described hold-down nut 4 and traveling nut 3 are hex nut; Described line-spacing adjusting screw 2 is common screw, diameter 6mm, length 12cm.

When use, first two bow pens are separately fixed in bow pen clips 1, then according to engineering construction needs, the distance that regulates traveling nut 3 to determine between two bow pens guarantees that two bow pens are identical apart from the distance between center locating pin 7 simultaneously; Subsequently, hold handle 6 and move, center locating pin 7 advances along the direction of irregular cracks, and bow pen starts line, and guide pin 5 can be used as with reference to revising in time direction of travel in the time of line, finally marks and equidistant two graticules in crack.
