Abstract
The utility model relates to a scaffold hard-pulling device capable of achieving efficient recycle. The scaffold hard-pulling device capable of achieving efficient recycle comprises a pre-buried screw rod and a pulling steel pipe, wherein the pre-buried screw rod is a cutting section of a tension screw rod of a cast-in-place reinforced concrete shear wall and an additionally welded sealing-up steel plate pre-buried inside a pillar, one end of the pulling steel pipe is welded to a connection steel plate, a bolt hole is formed in the middle of the lower portion of the connection steel plate, and the pre-buried screw rod penetrates bolt hole of the connection steel plate of the pulling steel pipe and is connected through a nut in a screwing mode, so that a fixed hard pulling structure is formed. The scaffold hard-pulling device capable of achieving efficient recycle utilizes the tension screw rod (a tension screw rod head after cutting) which is used as waste iron originally and used for supporting a mold to the greatest extent, the pulling section is designed into a finalized product, so that cycling utilization is convenient. The whole hard pulling device is beautiful, practical, economical, and environment-friendly.
Description
Technical field
The utility model 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 in cast-in-situ steel reinforced concrete shear wall, post, steel plate for sealing water has been welded in pre-buried adding, the recycling rate is very low, often is used as scrap iron and processes.The utility model device takes 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.
The utility model content
The utility model is the reusable technical problem that will solve the hard draw knot device of scaffold, and a kind of pin stiffness of hand in children drawknot device of realizing that high efficiente callback utilizes is provided.
The technical solution of the utility model 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, 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 is greater than 20cm, adds the spacing steel plate of weldering 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 beneficial effects of the utility model are: the utility model farthest uses makes the formwork Screw arbor with nut at both-ends (the Screw arbor with nut at both-ends head after 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.

The specific embodiment
As shown in Figure 1, a kind of pin stiffness of hand in children drawknot device of realizing that high efficiente callback utilizes comprises pre embedded bolt 1, spacing steel plate 2, junction steel plate 3, drawknot steel pipe 4, nut 6 etc.
Pre embedded bolt 1 penetrates in the junction steel plate bolt hole 5 of drawknot steel pipe 4 and tightens connection with nut 6, forms fixing hard draw junction structure.Effective drawknot when satisfying the pin hand and set up between pin hand and agent structure.
As shown in Figure 2, pre embedded bolt 1 is to have utilized pre-buried adding in cast-in-situ steel reinforced concrete shear wall, post to weld the split bolt termination section of steel plate for sealing water, and the coupling part of device is designed to the regularization product.Be constructed as follows:
Pre embedded bolt 1: adopt pre-buried adding in the cast-in-situ steel reinforced concrete shear wall cut down, post to weld the Screw arbor with nut at both-ends termination section of steel plate for sealing water, be generally the plain bar of diameter 14mm, 16mm, length is greater than 20cm.Require the silk tooth complete.Adding the wide X of the long X of weldering at distance screw rod silk tooth side end 60mm place thick is the spacing steel plate 2 of 30*30*3, and matching nut 6.
Pre embedded bolt 1 is pre-buried before concreting, fixes in beam, the boring of plate side form, reinforcing bar spot welding.
As shown in Figure 3, drawknot steel pipe 4(is designed to the regularization product): adopt the building operations scaffold tubes of diameter 48mm, wall thickness 3.5mm, length is preferably 450-500mm, and an end is thick with the wide X of long X is 3 weld all arounds of 100*60*8 junction steel plate.The bolt hole 5(that aperture 16mm or 18mm are offered in the middle part, bottom of junction steel plate 3 sees Fig. 4).
