Description
Technical field
The utility model relates to a kind of anchor clamps, relates in particular to a kind of special fixture of fixed mast.
Background technique
In the high-rise frame structure construction, often all design rigid steel pile, rigid steel pile are arranged is as stressed member important in the structure.The rigid steel pile design weight is bigger, and especially Di Bu structure floor height height, rigid steel pile weight is big, makes troubles to site operation.Existing rigid steel pile is installed the general crane that adopts big elevating capacity, but the investment of the crane of big elevating capacity is big, the cost height.For the general common crane that lifts 6 tons highly versatile in scene, the lifting rigid steel pile seems very not enough again, therefore if can solve high, the big lifting component of weight of bottom floor height, is the problem of economy and safe contradiction.
Under the prerequisite that does not increase the big elevating capacity crane, how to adopt easy lifting method, guarantee the special lifting requirements of engineering, be the problem that needs solve.
A kind of solution is to adopt the mast lift-on/lift-off system, promptly earlier rigid steel pile is lifted near working surface, adopts special cart steel column to be moved near the position of installation again, then by the mast lift-on/lift-off system just the rigid steel pile lifting put in place.But how mast is installed the rigid steel pile lifting can be put in place? common mast lift-on/lift-off system all adopts wire rope to make cable rope, manpower or crane handling lifting rod member.
Summary of the invention
The purpose of this utility model is to provide a kind of no cable rope independence mast lifting rigid steel pile special fixture, and this special fixture is simple in structure, mast can be fastened on the rigid steel pile that construction casting has finished, and fixation is reliable.
To achieve these goals, the utility model adopts following technological scheme:
A kind of no cable rope independence mast lifting rigid steel pile special fixture comprises supporting steel plate, jig main body, bolt, the curved screw bolt and nut of double end; Described jig main body is a head shoulder shape, the both sides of shoulder have through hole, the curved bolt of double end passes the jig main body through hole and is pinned by nut, the shoulder bottom of curved bolt of double end and jig main body surrounds and pins mast, the jig main body head has tapped hole, head dual-side portion is the inclined-plane, and head dual-side portion matches with the both side ends of workpiece; Described supporting steel plate middle part has through hole, and the supporting steel plate two end part are the inclined-plane, matches with the inboard face of workpiece in the supporting steel plate two end part; Described bolt passes supporting steel plate through hole and jig main body head threads hole being threaded, and jig main body and supporting steel plate are lock onto on the workpiece.
The inclined-plane of the head dual-side portion of described jig main body is 45 degree; The inclined-plane at described supporting steel plate two end part is 45 degree.
Described jig main body shoulder bottom is the imploded arcs shape.
Described double end is bent the U-shaped that is shaped as of bolt, and the U-shaped bottom is a semicircle.
Special fixture of the present utility model adopts jig main body and the curved bolt of double end that mast is surrounded and pins, supporting steel plate and bolt are fixed on jig main body on the workpiece (construction casting finish lower floor's rigid steel pile), thereby mast is fastened on lower floor's rigid steel pile.This special fixture is simple in structure, and fixation is reliable, thereby is to adopt the rigid steel pile on independent mast lifting top to lay the foundation.
So-called independent mast: be exactly to utilize special fixture independent mast (seamless steel pipe) to be clamped on the lower floor's rigid steel pile that possesses certain build-in ability, on the set console of independent mast top, hang up electric wire hoist and lift and need the rigid steel pile installed.Adopt independent mast lift-on/lift-off system, its user cost is low, value is high, the personnel that participate in construction are as long as 2-3 people just can lift by crane rigid steel pile, thereby overcome former employing wire rope as the fixing method of mast, need loaded down with trivial details to control rough sledding such as the length of cable rope, pulling force size back and forth, and defective such as required labour force is many.
Description of drawings
Fig. 1 does not have cable rope independence mast lifting rigid steel pile special fixture structural representation for the utility model;
Fig. 2 looks schematic representation for the master of jig main body;
