Abstract
The utility model discloses a multifunctional draw bar device of a construction formwork. The multifunctional draw bar device of the construction formwork is simple in structure, easy to manufacture and high in turnover rate and can be reused, and resources are saved. The multifunctional draw bar device comprises a working screw (1), tool screws (2), conical nuts (3), nut gaskets (4), tightening nuts (5), a water stop plate (6) and formworks (7), wherein the water stop plate (6) is fixedly mounted in the middle of the working screw (1), threads are respectively arranged at two ends of the working screw (1) and two ends of each tool screw (2), the two ends of the working screw (1) are respectively connected with one ends of the tool screws (2) by the conical nuts (3), and the formworks (7) are fixedly clamped on the tool screws (2) via the tightening nuts (5). The multifunctional draw bar device is high in practicality and turnover rate, and can be reused, the resources are saved, and cost is reduced while the efficiency is improved.
Description
Technical field
The utility model relates to a kind of building draw rod device, especially relates to the building construction formwork draw rod device of the technical field of civil engineering such as industry, civil building engineering, municipal public engineering, road and bridge.
Background technology
At present, be used for the Screw arbor with nut at both-ends of fixing concrete wall formula or thin wall construction template, be generally homemade smooth bar screw rod or thin steel band tie rod.In order to have enough to meet the need use, often at a round steel screw rod PVC plastic pipe of cover or concrete prefabricated pipe, after form removable, Screw arbor with nut at both-ends is extracted out.Facts have proved: in concreting process, sleeve pipe on the screw rod is owing to suffering concrete repeatedly impact, sink pressure or the casual collision of vibrating head etc., easily cause sleeve pipe distortion or breakage in various degree, cause the variation of template size thereupon, cause cement paste to infiltrate in the sleeve pipe, the quantity that causes Screw arbor with nut at both-ends to be released after theing cement solidifies is also few.Adopt such way, the disposable consumption of Screw arbor with nut at both-ends more, obviously uneconomical; On the other hand, after the form removable, the screw rod that is exposed at the works surface outward need to cut or cut away, and stays irregular hole at concrete structural surface, has not only increased the input of manpower and materials, and has affected the concrete structure apparent mass.
The utility model content
The purpose of this utility model is the deficiency for existing product, and provide a kind of simple in structure, be easy to make, standardization level is high, versatility good, reliable in quality, assembly and disassembly are convenient, reusable building construction formwork Multifunctional pull rod device.
Building construction formwork Multifunctional pull rod device of the present utility model, described device comprises forwardtransfer signal worm, instrument screw rod, tapered cup nut, nut shim, tightening nuts, sealing piece, template, described sealing piece is fixedly mounted on the forwardtransfer signal worm middle, described forwardtransfer signal worm, instrument screw rod two ends are equipped with screw thread, the forwardtransfer signal worm two ends are connected with instrument screw rod one end by tapered cup nut respectively, and template is fixedly clamped on the instrument screw rod by tightening nuts.
Described nut shim is butterfly card or mountain type card.Described sealing piece and forwardtransfer signal worm connected mode be adhesive bonding or the welding.Described forwardtransfer signal worm is indented bars or round steel.Described tapered cup nut and sealing piece material are tool steel or Wear-resistant engineering plastic.
The beneficial effects of the utility model are: (1) adopts standardized designs, batch production production, has improved operating efficiency, has guaranteed quality; (2) forwardtransfer signal worm, tapered cup nut and tightening nuts are reusable, can economize on resources, reduce cost; (3) fixed to concrete wall type or the precise control of thin wall construction template inside dimension, inner and outer template, waterproof, stagnant water effect are good; (4) behind instrument screw rod, tapered cup nut removal, the bellmouth that concrete structural surface is left over is easy to repair, and does not affect outward appearance.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure: forwardtransfer signal worm 1, instrument screw rod 2, tapered cup nut 3, nut shim 4, tightening nuts 5, sealing piece 6, template 7.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
In the drawings, structure of the present utility model mainly is comprised of forwardtransfer signal worm 1, instrument screw rod 2, tapered cup nut 3, nut shim 4, tightening nuts 5, sealing piece 6, template 7.
Sealing piece 6 is bonding or be welded and fixed and be installed in forwardtransfer signal worm 1 middle by adhesive, and sealing piece 6 materials are high-strength engineering plastic, and forwardtransfer signal worm 1 material is elected the HRB335 indented bars as.
Forwardtransfer signal worm 1, instrument screw rod 2 two ends are equipped with screw thread, and forwardtransfer signal worm 1 two ends are connected with instrument screw rod 2 one ends by tapered cup nut 3 respectively, and tapered cup nut 3 materials are tool steel or Wear-resistant engineering plastic; Template 7 is fixedly clamped on the instrument screw rod by rotation tightening nuts 5 and nut shim 4, can become building construction formwork waterproof, sealing Multifunctional pull rod device; Butterfly card or mountain type card that nut shim 4 causes for the 4A3 steel.
Forwardtransfer signal worm 1, tapered cup nut 3, tightening nuts 5 can be had enough to meet the need use, can economize on resources, reducing construction cost; Behind instrument screw rod 2, tapered cup nut 3 removals, the bellmouth that concrete structural surface is left over is easy to repair, and does not affect its outward appearance.
Above an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All variation and improvement of doing according to the utility model application range all should still belong within the patent covering scope of the present utility model.
