Abstract
The utility model discloses a steel chisel for road paving construction layout. At present, the steel chisels for suspending datum lines of pavers in the road construction are various, and almost temporarily manufactured and have a lot of defects that the height adjustment is convenient, the working efficiency of workers is reduced, and paving quality is affected by elevation change during a tightening process of the datum line due to the insufficient fastening force of a main rod or a transverse rod. The steel chisel comprises a steel chisel main rod (1) with a pointed bottom, wherein the steel chisel main rod passes through a circular steel tube (3) of a steel chisel transverse rod (2); a nut (4) is welded on the circular steel tube; a fastening screw hole (5) is formed in the circular steel tube corresponding to the nut; a fastening screw (6) is arranged on the nut; the circular steel tube is connected with flat steel (7); and a datum line slot (9) and a datum line wiring clamp slot (9) are formed in the two sides of the flat steel respectively. The steel chisel disclosed by the utility model is used for suspending the datum line for paving construction layout of the paver in the road construction.
Description
Technical field:
The utility model relates to a kind of highway construction lofting drill rod that paves.
Background technology:
At present, be used for to hang the pave drill rod of reference line of paver in construction of the highway, of a great variety, unified standard, be not all interim making basically, has many shortcomings.For example: highly regulate inconvenience, reduced workman's efficient.Another shortcoming is that the fastening force of mobile jib or cross bar is inadequate, causes elevation to change when the reference line tensioning, affects spreading quality.Also having a shortcoming is should not keep in repair when being damaged.
Summary of the invention:
The purpose of this utility model is to provide a kind of highway construction lofting drill rod that paves, and makes the construction lofting that paves convenient, accurate.
Above-mentioned purpose realizes by following technical scheme:
A kind of highway construction lofting drill rod that paves, its composition comprises: the bottom is pointed drill rod mobile jib, described drill rod mobile jib passes the round steel pipe of drill rod cross bar, be welded with nut on described round steel pipe, has top wire hole on described round steel pipe corresponding to described nut, on described nut, jackscrew is installed, described round steel pipe is connected with band steel, and the both sides of described band steel have respectively benchmark wire casing, reference line wiring draw-in groove.
The described highway construction lofting drill rod that paves, the internal diameter of described nut equates with the diameter of described top wire hole.
The described highway construction lofting drill rod that paves, described round steel pipe and described band steel are integrated.
Beneficial effect:
1. the utility model is easy to adjust, as long as unclamp the random adjusting that jackscrew just can be accomplished up and down, angle, can shorten the setting-out time, increases efficient; Increase simultaneously the fastening force of cross bar, can offset the tensile force of reference line, made the measured cross bar of survey can not change elevation when the reference line tensioning, increased accuracy rate; In the suburb or the field, the design of this product has taken into full account the link of processing and fabricating due to the construction of the highway great majority, and this production is simple, and only needing a prevailing minicomputer to add the workshop just can processing and fabricating, convenient, flexible; Also have the arbitrary parts damages of this product can accomplish to change at any time.
2. the utility model is avoided in construction of the highway paver paving process, cause thickness and the vertical error of construction because of the supporter error that hangs reference line, the drill rod mobile jib of bottom through forging, harder, the center to center distance with the benchmark wire casing that has top wire hole on round steel pipe is fixed, make calculating more accurate, improve construction quality.Drill rod mobile jib and round steel pipe two parts fit clearance are reasonable, increase the degree of accuracy.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is structural representations of drill rod cross bar in accompanying drawing 1.
Accompanying drawing 3 is structural representations of round steel pipe and band steel in accompanying drawing 1.
Structural representation.
The specific embodiment:
Embodiment 1:
A kind of highway construction lofting drill rod that paves, its composition comprises: the bottom is pointed drill rod mobile jib 1, described drill rod mobile jib passes the round steel pipe 3 of drill rod cross bar 2, be welded with nut 4 on described round steel pipe, has top wire hole 5 on described round steel pipe corresponding to described nut, jackscrew 6 is installed on described nut, and described round steel pipe is connected with band steel 7, and the both sides of described band steel have respectively benchmark wire casing 8, reference line wiring draw-in groove 9.
The drill rod mobile jib adopts GB Φ 18 round steel, and the bottom is harder through forging, and the round steel pipe that size is determined can be accomplished convenient height and the angle of regulating, and is that the construction that paves is convenient, accurate, improves construction quality.
Round steel pipe adopts the steel pipe of GB Φ 20 * 25 * 2.5mm, and band steel adopts 55 * 50 GB band steels.Reference line groove center and pipe center to center distance are 20mm; Reference line wiring draw-in groove is reference line wiring draw-in groove; Top wire hole uses the M10 nut-welding on the tube wall of round steel pipe; Jackscrew adopts the M10 screw rod.
Drill rod mobile jib bottom is forged hard; Round steel pipe center and reference line groove center are apart from determining; Mobile jib coordinates rationally with cross bar.
Embodiment 2:
The above-mentioned highway construction lofting drill rod that paves, the internal diameter of described nut equates with the diameter of described top wire hole.
Embodiment 3:
The above-mentioned highway construction lofting drill rod that paves, described round steel pipe and described band steel are integrated.
Claims (3)
1. highway construction lofting drill rod that paves, its composition comprises: the bottom is pointed drill rod mobile jib, it is characterized in that: described drill rod mobile jib passes the round steel pipe of drill rod cross bar, be welded with nut on described round steel pipe, has top wire hole on described round steel pipe corresponding to described nut, on described nut, jackscrew is installed, described round steel pipe is connected with band steel, and the both sides of described band steel have respectively benchmark wire casing, reference line wiring draw-in groove.
2. the highway according to claim 1 construction lofting drill rod that paves, it is characterized in that: the internal diameter of described nut equates with the diameter of described top wire hole.
3. the highway according to claim 1 and 2 construction lofting drill rod that paves, it is characterized in that: described round steel pipe and described band steel are integrated.
