Abstract

The utility model relates to a rapid and easy-dismounting column capital positioned by a positioning support, a lead screw and a straight-line wedge, which belongs to the field of building construction formwork engineering. In engineering, the easy-dismounting column capital mainly includes ring clamp type, pin type and bolt type; the ring clamp type and the pin type can be rapidly dismounted, but has complex structure and high cost and is bulky and easy to break due to falling onto ground; and the bolt type can not be rapidly dismounted, and the support frame is rotary. The rapid and easy-dismounting column capital is mainly characterized in that the positioning support and the lead screw are fixed with the straight-line wedge, a round holes is formed on the positioning support in the vertical direction and a square hole is formed on the positioning support in the longitudinal direction, the lead screw can pass into the round hole, the straight-line wedge can pass into the square hole, the distance between the two holes is set to a proper degree that the straight-line wedge can fasten the lead screw, and a trapezoidal corrugation corresponding to the lead screw is arranged on the inner side of the straight-line wedge. After the straight-line wedge is knocked to be tightened, the trapezoidal corrugation on the inner side of the straight-line wedge is engaged and fastened with the trapezoidal threads of the lead screw, so as to complete positioning by friction self-locking; and the lead screw is fastened at the center of the support, the support can bear the load of a weight to counter-knock the straight-line wedge, so that the positioning support rapidly slide down along the lead screw.

Description

A kind of quick detach by location holder, leading screw and word wedge location is early torn column cap open

Technical field

The utility model belongs to the form work engineering field of executing of building.

Background technology

Early-dismantling is one of 10 new technologies of Ministry of Construction's builing industry, by early tearing the turnover that to accelerate template and support open, save investment, reduce cost, and the technology of early tearing open realizes by tearing column cap morning open usually, the location of wherein early tearing column cap open is the core of this technology, early tear column cap open and mainly contain ring clip, three kinds of pin type and nut formulas, see for details shown in the 4th 96 pages of Figure 17-137 of building operations handbook (third edition) and the 108th page of Figure 17-158, ring clip wherein, it is quick disassembled that pin type is early torn column cap open, but complex structure, heaviness, fearness is fallen, the cost height, bearing capacity is low, and holder frame momentum is big, though and that the nut formula is early torn column cap open is simple in structure, cost is low, but not quick disassembled, and holder frame momentum is big and can rotate.

Summary of the invention

In order to solve above three kinds of deficiencies of tearing column cap morning open, it is not only simple in structure but also functional to make tear column cap open morning, the technical solution adopted in the utility model is: a kind of quick detach by location holder, leading screw and word wedge location is early torn column cap open, he by leading screw, column cap plate, nut, little nut, a word wedge, and holder form, the feature of each parts is as follows: (following length all is unit with the millimeter) first leading screw, length is not limit, be advisable with 600, acme thread, external diameter 34-39 erects and uses; The second column cap plate is steel plate or the u shape plate of 100*100*10, is welded in leading screw upper end and vertical with leading screw; The 3rd nut with leading screw coupling, is combined into bolt, about establish handle, be convenient to knock rotation; The 4th little nut, external diameter 6 is about 35; May Day, the word wedge was about 150, and high about 20, width is beloid, and intermediate width is about 180, and gradient is less than the static friction angle, and the trapezoidal ripple corresponding with leading screw established in the side that a word wedge contacts with leading screw, and a small sircle hole is established at the tip of wedge; The 6th location holder, each shoulder about holder, shoulder is encorbelmented, word order, section is a T shape, and stretching out diminishes gradually, and point of shoulder is established rib, vertical and front and back, holder middle part are to establishing the hole, vertical is circular hole, and front and back can penetrate leading screw to being square hole in the circular hole, can penetrate a word wedge in the square hole, square hole is in a side of circular hole, and the distance in two holes can be advisable by fastening leading screw with a word wedge, and middle flat cutting face is a flat oval, vertical core high about 40, wall thickness is about 8, vertically establishes an arc groove at the circular hole opposite side, groove dark about 3, arc is about 1/5th of leading screw girth, and groove plays fixedly leading screw front and back position; During assembling leading screw is inserted in the location holder vertical core, one word wedge is inserted in the sagittal square hole of location holder, then the small sircle hole at a word wedge tip is fixed with little nut, make word wedge front and back push-and-pull only, can not withdraw from, by the height of early tearing requirement open one word wedge is struck tightly during use, just interlock is fastening for the trapezoidal ripple of one word wedge inboard and the ladder shell line of leading screw, friction self-locking, positioning instant is finished, and just is being fastened on the central authorities of holder this moment in the leading screw quilt, holder can be carried weight, strike back it during dismounting, holder is just vertically glided along leading screw, plays the effect of quick detach.

The beneficial effects of the utility model are simple in structure, and are easy to operate, in light weight, and at the bottom of the cost, holder is not rotated, and frame is not moving, and supporting capacity height, quick detach are early torn open effective.

The specific embodiment

The leading screw of this product, column cap plate, nut, little nut all are the universal products, and a word wedge and location holder casting get final product, and press earlier the assembly drawing assembling, by the height of early tearing requirement open one word wedge is struck tightly during use, positioning instant is finished, and strikes back it during dismounting again, holder is just vertically glided along leading screw, reaches the quick detach effect.
