Abstract

The utility model relates to a construction tool, in particular to a pull screw used for the fixing concrete blinding. The problem of low efficiency for the normal pull screw and the waste in prior art is solved. The construction tool provided by the utility model includes a screw rod; one end of the screw rod is a ring, and the other end is coated with a fastening screw cap. The screw rod and the fastening screw cap can be repeatedly used, and the cutting operation is not needed, the usage amount of the screw caps is reduced by half, and the loss is lightened; meanwhile, the turnbuckle and the template are not easy to damage in the process of detaching, which saves material and labor force, and reduces the engineering cost.

Description

The Screw arbor with nut at both-ends that the fixing concrete template is used
Technical field
The utility model relates to a kind of building operations apparatus, is specially the Screw arbor with nut at both-ends that a kind of fixing concrete template is used.
Background technology
Form work engineering is the technology basis of concrete structure moulding, and the control of strengthening form work engineering is the key point that improves the concrete formation quality.In the template construction of wall, wall, post, existing way is to come drawknot medial and lateral template with common Screw arbor with nut at both-ends or band iron, and bears concrete lateral pressure and load, guarantees that the distance between the template of medial and lateral is indeformable.It also is the fulcrum of template and braced structures thereof simultaneously, directly affects globality, rigidity and the intensity of formwork structure.Anticipate as shown in Figure 1, the structure of common Screw arbor with nut at both-ends is made up of the nut of round steel screw rod and two ends socket, and the round steel screw rod passes the medial and lateral template, overlaps upper cap nut then, by the mould phenomenon that rises behind the concrete perfusion between the nut control template.But find that in practice there is following point in this Screw arbor with nut at both-ends: after 1, concrete soil solidifies, the round steel screw rod is difficult to extract under concrete parcel squeezing action, basically can only disposablely use, if the method that employing is firmly beaten is damaged screw thread again when pulling out screw rod by force easily.2, since template may fix by many screw rods, so when stripping large tracts of land template difficulty comparatively when many irons move, mobilely by force be easy to damage template again.3, the nut volume is little, loses easily, is not easy to keeping.4, can only cut out the waste material lost labor with methods such as gas cuttings for the screw rod that is exposed at concrete surface outward.5, screw rod need maintain with machine oil at ordinary times, catches greasy dirt at concrete surface easily in the use, needs to clear up basic unit before plastering, and increases engineering cost.
Summary of the invention
The utility model for solve the common Screw arbor with nut at both-ends that exists in the prior art use in inefficiency, the serious problem of waste and the Screw arbor with nut at both-ends that provides a kind of fixing concrete template to use.
The utility model is realized that by following technical scheme the Screw arbor with nut at both-ends that a kind of fixing concrete template is used comprises screw rod, and an end of screw rod is ring, and the other end is socketed with fastening nut.
Compared with prior art, the utility model has following advantage in construction, one end of screw rod is ring, can in ring, insert instruments such as reinforcing rod, by the rotation reinforcing rod screw rod and fastening nut being relatively rotated locks, when dismounting, also can adopt same way that screw rod and fastening nut are unclamped equally, thereby at an easy rate screw rod be extracted from concrete.Like this screw rod and fastening nut can reuse, and need not cutting operation, and the use amount of nut also reduces half, loss alleviates, simultaneously in the process of disassembling, also be not easy to damage screw thread and template, have the material of saving and artificial, reduce the characteristics of engineering cost.
Description of drawings
Fig. 1 is existing Screw arbor with nut at both-ends structural representation
Fig. 2 is a structural representation of the present utility model
Fig. 3 is a user mode structural representation of the present utility model
Among the figure: 1-ring, 2-screw rod, 3-fastening nut, 4-reinforcing rod, 5-steel pipe, 6-cushion block, 7-template, 8-isolated tube, 9-butterfly card
The specific embodiment
Anticipate as shown in Figure 2, the Screw arbor with nut at both-ends that a kind of fixing concrete template is used comprises screw rod 2, and an end of screw rod 2 is ring 1, and the other end is socketed with fastening nut 3.
Meaning also is with at least one butterfly card 9 on screw rod 2 as shown in Figure 3.Be inserted with reinforcing rod 4 in the ring 1,4 pairs of screw rod 2 moments of reinforcing rod are rotated screw rod, knock the other end of screw rod then and it can be extracted out.Butterfly card 9 generally has two, lays respectively at inside and outside template 7 both sides, and the effect of butterfly card 9 is to be fixed in template 7 outer field steel pipes 5, increases the usage quantity that steel pipe quantity can reduce Screw arbor with nut at both-ends equally.
Screw rod is easier to be extracted in order to make, and also is with isolated tube 8 on screw rod 2.Isolated tube can be organic flexible material such as PVC plastic production.
When the needs waterproof, cross-under sealing piece outside the isolated tube 8 on screw rod, when dismantling screw, the sealing piece is stayed in the concrete, and the sealing piece is generally made with regard to the rubber that expands by running into water, fills expansive cement at last and get final product in isolated tube 8.
