Description
Technical field
The utility model belongs to the servicing unit of asphalt paving, especially relates to a kind of grade stake of asphalt paving.
Background technology
In highway construction, because asphalt paver needs to put altitude traverse with grade stake, when putting altitude traverse at the construction field (site), usually the montant of grade stake is squeezed in ground, and the horizon bar of grade stake is welded on steel bushing, then steel bushing is sleeved on montant and with fastened by screw and locates, in construction, just need a people while measure absolute altitude, unscrew screw with spanner, up and down tighten the screws again after adjustment steel bushing.Not only screw loosen, tighten cumbersome, and easily cause absolute altitude to be forbidden, in the repetition measurement process of altitude traverse, often have more height variation.
Summary of the invention
The purpose of this utility model proposes a kind of sliding grade stake, and not only structure is simple, easy to use and reliable, and effectively improves efficiency of construction and the quality of asphalt paving, reduces construction cost.
The purpose of this utility model is achieved like this: a kind of sliding grade stake (abbreviation grade stake), comprise montant and horizon bar, this montant and horizon bar are that cross is arranged, it is characterized in that: this sliding grade stake also comprises elastic clip, described elastic clip primarily of be connected upper slice, bottom sheet, anter and rear panel composition, on described elastic clip upper slice, bottom sheet, anter, rear panel is all rectangle, described elastic clip can be made with spring steel plate, by on described elastic clip upper slice, bottom sheet bends to circular arc to the right symmetrically respectively, and this curve circular arc upper slice, bottom sheet is offered symmetrically respectively the hole be positioned on same vertical center line
i,in these upper and lower two holes
iin install montant, described montant by curve circular arc upper slice, the elastic deformation of bottom sheet and be fixed on elastic clip, simultaneously, anter on described elastic clip, rear panel are also bent to circular arc to the right symmetrically respectively, and curves in the anter of circular arc, rear panel at this and offer the hole II be positioned on same level center line symmetrically respectively
,and make the line of centres in this hole II correspondence be positioned at the position, right side of the line of centres in hole I
,in these former and later two holes II, install horizon bar, described horizon bar is by curving the anter of circular arc, the elastic deformation of rear panel and being fixed on elastic clip.
During use, only need with hand to clutch toward inner side on elastic clip upper slice, bottom sheet, just can move up and down this elastic clip along montant, make horizon bar move up and down together simultaneously, unclamp elastic clip upper slice, bottom sheet, horizon bar just can be made to be fixed positioned on montant, easy and simple to handle, easy.
The sliding grade stake that the utility model proposes, not only structure is simple, easy to use and reliable, and improves efficiency of construction and the quality of asphalt paving, reduces construction cost.
Now in conjunction with the accompanying drawings and embodiments the sliding grade stake that the utility model proposes is further described.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the sliding grade stake that the utility model proposes.
In Fig. 1: 1, montant 2, horizon bar 3, elastic clip 3-1, upper slice 3-2, bottom sheet 3-3, anter 3-4, rear panel.
Detailed description of the invention
As can be seen from Figure 1: a kind of sliding grade stake (abbreviation grade stake), comprise montant 1 and horizon bar 2, this montant 1 is arranged in cross with horizon bar 2, it is characterized in that: this sliding grade stake also comprises elastic clip 3, described elastic clip 3 is primarily of the upper slice 3-1 be connected, bottom sheet 3-2, anter 3-3 and rear panel 3-4 composition, and the upper slice 3-1 on described elastic clip 3, bottom sheet 3-2, anter 3-3, rear panel 3-4 is all rectangle, described elastic clip 3 can be made with spring steel plate, by the upper slice 3-1 on described elastic clip 3, bottom sheet 3-2 bends to circular arc to the right symmetrically respectively, and upper slice 3-1 of circular arc is curved at this, bottom sheet 3-2 offers symmetrically respectively the hole be positioned on same vertical center line
i,in these upper and lower two holes
iin install montant 1, described montant 1 is by curving upper slice 3-1 of circular arc, the elastic deformation of bottom sheet 3-2 and be fixed on elastic clip 3, simultaneously, anter 3-3, rear panel 3-4 on described elastic clip 3 are also bent to circular arc to the right symmetrically respectively, and offer the hole II be positioned on same level center line symmetrically respectively on anter 3-3, the rear panel 3-4 that this curves circular arc
,and make the line of centres in this hole II correspondence be positioned at the position, right side of the line of centres in hole I
,in these former and later two holes II, install horizon bar 2, described horizon bar 2 is by curving the anter 3-3 of circular arc, the elastic deformation of rear panel 3-4 and being fixed on elastic clip 3.
During use, only need upper slice 3-1, the bottom sheet 3-2 that to clutch toward inner side with hand on elastic clip 3, just can move up and down this elastic clip 3 along montant 1, make horizon bar 2 move up and down together simultaneously, unclamp upper slice 3-1, the bottom sheet 3-2 on elastic clip 3, horizon bar 2 just can be made to be fixed positioned on montant 1, easy and simple to handle, easy.
