Abstract

A combined screw bolt used to stabilize shuttering engineerings such as concrete foundation, shear wall, beam and column is composed of internal and external screw bolts and connecting rod. It features no need of welding and cutting, easy assembly and disassembly, low cost and high engineering quality.

Description

Assembled screw rod

1, assembled screw rod is according to building operations, and is that the needs of form work engineering are developed, it is used and form work engineerings such as firm various concrete, basis, shear wall, board wall, beam, post are best product.

2, assembled screw rod calculates through interrelated data, its lowest pull is 0.9 ton, actual sampling examination is drawn, minimum is stressed is not less than 1.9 tons, every square metre of maximum side force degree of template side elevation is not more than 5.6 tons, so the proof assembled screw rod is stressed with enough templates, when firm template, 50 centimetres of horizontal spacings, perpendicular spacing are commute for 60 centimetres.

3, the purpose of assembled screw rod development, speed, the safety of guaranteeing engineering and the workmanship of construction for convenience, minimizing recruitment, quickening formwork erection engineering are pushed form work engineering to a new step.

4, assembled screw rod mainly is made up of inner screw, external screw rod, connecting rod;

(1), inner screw plays absolute effect to assembled screw rod; the silk hole is connected with connecting rod behind the inner screw, preceding silk head is used and be connected external screw rod; 8 centimetres of inner screw length; for just with installation and removal, half long for square, half long for circular, square be the dismounting effect; circle plays effect easy for installation; for preventing that inner screw from being stopped up by concrete; to adding wineglass formula plastics protected enclosure above the inner screw; inner screw is protected; inner screw can be dismantled on time, can repeatedly use, in when dismounting, use autocratic wrench dismounting.

(2), external screw rod divides in two kinds, 20 centimetres of a kind of length, another kind of long 15 centimetres, can select for use according to the size of template, external screw rod compares with existing screw rod, do not need to weld, operation such as gas cutting, straightening, hard waste, can dismantle template on time, can repeatedly use again, as adding the zinc-plated advantage that can use for many years, play the external mold overall fixed, fastening good effect.

(3), the inner screw of connecting rod and both sides plays interconnect function, a connecting rod just can replace an existing screw rod to use, it plays fixing and control template home record size.

5, the screw rod of the existing usefulness of China, as accompanying drawing 5, existing screw rod Fig. 1, Fig. 2, make complicated, operation is inconvenient again, it generally is disposable use, concrete shear force wall as 40 cm thicks, need long about 90 centimetres screw rod, a screw rod processing maturation will spend RMB more than 3 yuan, every square metre just needs about 6 screw rods, every square metre concrete shear force wall form work engineering, screw rod cost will about 20 yuan, above as the pre-buried bamboo trunk of typical floor, screw rod was scurried in bamboo trunk, 40% stopped up by concrete grout also arranged, screw rod can't pump out, the straightening again of releasing, hard waste, the concrete wall surface seepage can't be repaired, the screw rod that can't pump out is gas cutting again, form removal on time, and damaged template is very big, the concrete spillage is serious, joint rots root, wall leakage, wasted a large amount of funds, material and artificial, welding slag is fallen above the scaffold fire hazardous again during the gas cutting screw rod, the bar head of the cutting off weakness that falls and easily hurt sb.'s feelings etc.

6, the assembled screw rod moulding is simple, easy to operate, use is wide, can repeatedly use, add zinc-plated can the use for many years above the screw rod, an assembled screw rod is with once just saving about three yuans, it can guarantee engineering safety and workmanship again, form removal on time again, concrete shear force wall template as same upright 40 cm thicks, a screw rod only need spend about three maos, as long as use 32 centimeter length, 0.8 a connecting rod of cm diameter just can, do not need to weld gas cutting, straightening, the hard waste formwork erection has the advantage of running mould anything but, and casting and compacting of concrete is spillage not, and metope is non-leakage rainy season, template there is not damage, on the basis of guaranteeing workmanship and engineering safety, can save a large amount of funds, material, manually.

7, (1), " each dimension figure of accompanying drawing full-page proof is unit with the millimeter, " accompanying drawing 1, assembled screw rod figure, section divide A, B, C, D, figure, A figure at accompanying drawing 2, B, C, D, figure, assembled screw rod installation drawing.At accompanying drawing 3, installation drawing, 1 inner screw, 2 connecting rods, 3 external screw rods, 4 wooden forms, 5 wooden block sides, 6 cross bars, 7 headblock sheets, 8 iron gaskets, 9 cap nuts, 10 concrete.

(2), accompanying drawing 2, A figure, inner screw full-page proof, A1, plastics protected enclosure master drawing, A2 protective cover section size figure, A3, inner screw assembly drawing.

(3), accompanying drawing 3, B figure, inner screw drawing, C figure, external screw rod drawing, D figure, connecting rod drawing.

(4), the wrench figure that uses of accompanying drawing 4, dismounting inner screw, and inner screw dismounting figure, inner screw dismounting figure, 1 refer to that spanner figure, 2 refers to inner screw figure.

(5), accompanying drawing 5, existing screw rod Fig. 1, existing screw rod Fig. 2, and existing screw rod installation drawing, installation drawing, 1 screw rod, 2 sealing pads, 3 home records are spacing, 4 outer sealing pads, 5 templates, 6 holder sides, 7 cross bars, 8 headblock sheets, 9 iron gaskets, 10 cap nuts, 11 concrete.

(6), accompanying drawing 6, assembled screw rod Figure of abstract.

8, when mounting template, from inside to outside install, when dismantling, remove from outside to inside, please refer to when installing, accompanying drawing 1, assembled screw rod installation drawing.Please refer to during dismounting, accompanying drawing 4, inner screw dismounting figure dismounting, inner screw dismounting back hole in time mend with pea gravel concreten.
