Description
Technical field
The present invention relates to a kind of anchor clamps, relate in particular to a kind of special fixture of fixed mast.
Background technique
In the high-rise frame structure construction, often all be designed with rigid steel pile, rigid steel pile is as stressed member important in the structure.The rigid steel pile design weight is larger, and especially the structure floor height of bottom is high, 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 large, and cost is high.For the common crane of the highly versatile of 6 tons of the general liftings in scene, the lifting rigid steel pile seems again very not enough, therefore if solve high, the big lifting component of weight of bottom floor height, is the problem of an 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 Hoisting requirement of engineering, be the problem that needs solve.
A kind of solution is to adopt mast elevating, namely first rigid steel pile is lifted near working surface, adopts special cart steel column to be moved near the position of installation again, then by mast elevating 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 elevating all adopts wire rope to make cable rope, manpower or crane handling lifting rod member.
Summary of the invention
The object of the present invention is to provide that a kind of this special fixture is simple in structure without cable rope independence mast lifting rigid steel pile special fixture, mast can be fastened on the complete rigid steel pile of construction casting, fixation is reliable.
To achieve these goals, the present invention adopts following technological scheme:
A kind of without cable rope independence mast lifting rigid steel pile special fixture, comprise supporting steel plate, jig main body, bolt, the curved screw bolt and nut of double end; Described jig main body is 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 the curved bolt of double end and jig main body surrounds and pins mast, the jig main body head has tapped hole, head dual-side section is the inclined-plane, and head dual-side section 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 section 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.
The curved bolt of described double end be shaped as U-shaped, the U-shaped bottom is semicircle.
Special fixture of the present invention adopts jig main body and the curved bolt of double end that mast is surrounded and pins, and supporting steel plate and bolt are fixed on jig main body on the workpiece (the complete lower floor's rigid steel pile of construction casting), 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, hang up the rigid steel pile that electric wire hoist lifts needs installation at the set console of independent mast top.Adopt independent mast elevating, its user cost is low, value is high, 2-3 people participates in the personnel of construction as long as 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 back and forth the rough sledding such as the length of cable rope, pulling force size, and the defective such as required labour force is many.
Description of drawings
Fig. 1 is that the present invention is without cable rope independence mast lifting rigid steel pile special fixture structural representation;
Fig. 2 is that the master of jig main body looks schematic representation;
Fig. 3 is that schematic representation is looked on the left side of Fig. 2.
Among the figure: 1 supporting steel plate, 2 bolts, 3 jig main bodies, the curved bolt of 4 double ends, 5 nuts, 6 workpiece (the complete lower floor's rigid steel pile of construction casting), 7 masts (seamless steel pipe).
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of without cable rope independence mast lifting rigid steel pile special fixture, comprise supporting steel plate 1, jig main body 3, bolt 2, the curved bolt 4 of double end and nut 5;
Described jig main body 3 is head shoulder shape, referring to Fig. 2 and Fig. 3, the both sides of shoulder have through hole, the shoulder bottom is the imploded arcs shape, the curved bolt 4 of double end passes jig main body 3 through holes and is pinned by nut 5, the curved bolt 4 of double end be shaped as U-shaped, the U-shaped bottom is semicircle, the shoulder bottom of the curved bolt 4 of double end and jig main body 3 surrounds and pins mast 7, and mast 7 is seamless steel pipe; Jig main body 3 heads have tapped hole, and head dual-side section is the inclined-plane, and the inclined-plane is generally 45 degree, and head dual-side section matches with the biside plate end of workpiece 6; Described workpiece 6 is lower floor's rigid steel pile of construction casting moulding, and the section of rigid steel pile is generally cross four sides and adds flange plate.
