Abstract
The invention relates to a scaffold hard tying device capable of realizing efficient recycling. The scaffold hard tying device comprises an embedded screw and a tying steel pipe, wherein the embedded screw is a cutting segment of a counter-tension screw of a welded water sealing steel plate which is embedded in a cast-in-place reinforced concrete shear wall and a column, a connecting steel plate is welded on one end of the tying steel pipe, a bolt hole is formed in the middle of the lower part of the connecting steel plate, and the embedded screw penetrates through the bolt hole of the connecting steel plate of the tying steel pipe to form a fixed hard tying structure. By utilizing the device, the counter-tension screws (the cut counter-tension head screws) which are used for formwork supporting and are treated as scrap iron originally are utilized to the maximum extent, moreover, a tying segment is designed into a fixed product, so that repeated use is facilitated. The whole set of the hard tying device is attractive, practicable and economical and is conductive to environmental conservation.
Description
Technical field
The present invention relates to a kind of hard draw knot device of scaffold, especially a kind of hard draw knot device of realizing the scaffold that reuses.
Background technology
Traditional pin stiffness of hand in children drawknot is often taked the form of pre-embedded steel slab or short steel pipes, and steel plate or steel pipe need be purchased or monoblock steel plate, long steel pipe etc. be cut in addition, and a large amount of drawknots not only increases cost, and the rate of recovery after pre-buried is lower.Meanwhile, main structure construction often produces again a large amount of screw rods that can't normally use, the Screw arbor with nut at both-ends termination section that particularly steel plate for sealing water has been welded in pre-buried adding in cast-in-situ steel reinforced concrete shear wall, the post, the recycling rate is very low, often is used as scrap iron and processes.Apparatus of the present invention take full advantage of this part screw rod with the silk tooth, and with the supporting regularization product that is designed to of the linkage section of drawknot device, simple, practical, attractive in appearance.
Summary of the invention
The present invention is the reusable technical problem that will solve the hard draw of scaffold knot device, and a kind of pin stiffness of hand in children drawknot device of realizing that high efficiente callback utilizes is provided.
Technical scheme of the present invention is: a kind of pin stiffness of hand in children drawknot device of realizing that high efficiente callback utilizes, comprise pre embedded bolt, the drawknot steel pipe, pre embedded bolt is the cut length that adds the Screw arbor with nut at both-ends that welds steel plate for sealing water pre-buried in cast-in-situ steel reinforced concrete shear wall, the post, drawknot steel pipe one end is welded with junction steel plate, bolt hole is offered in middle part, junction steel plate bottom, and pre embedded bolt penetrates in the junction steel plate bolt hole of drawknot steel pipe and connects with nut screwing clamping, forms fixing hard draw junction structure.
Pre embedded bolt is full flight screw, the plain bar of its diameter 14mm or 16mm, and length adds the spacing steel plate of weldering greater than 20cm at distance screw flight leading section 60mm place
Pre embedded bolt is pre-buried before concreting to be fixed with reinforcing bar spot welding.
The drawknot steel pipe is the building operations scaffold tubes of diameter 48mm, wall thickness 3.5mm, and length is 450-500mm.The diameter of the bolt hole that the middle part, bottom of junction steel plate is offered is 16mm or 18mm.
The invention has the beneficial effects as follows: the present invention farthest uses and makes the formwork Screw arbor with nut at both-ends (the Screw arbor with nut at both-ends head after the cutting) that scrap iron is processed originally, simultaneously the drawknot section is designed to the regularization product, is convenient to turnover and uses.A whole set of hard draw knot device is attractive in appearance, practical, economical, environmental.
