Abstract
The utility model discloses an auxiliary positioning device for rebars. The auxiliary positioning device is characterized in that the auxiliary positioning device comprises a plurality of threaded rods which can be connected with one another, each threaded rod is connected with at least one pair of positioning disks through threads, each positioning disk comprises internal threads matched with threads of the corresponding threaded rod and an annular solid disk body extending to the outer edge from the internal threads, semi-U-shaped grooves are symmetrically formed in the two end faces of the solid disk body, and after every two adjacent disks are axially opposite to each other, a complete U-shaped groove is formed by the semi-U-shaped grooves between the two adjacent solid disk bodies; through pin holes are formed in the end faces, close to the outer edge, of the two sides of each solid disk body so that positioning pins can be inserted in the pin holes. According to construction requirements, multiple positioning intervals can be formed by lengthening the threaded rods and adding the positioning disks.
Description
Technical field
The utility model relates to a kind of servicing unit that forms multiple location spacing while making reinforcement installation.
Background technology
In existing construction method, reinforcing bar location is a link more rambunctious always, very easily causes mass defect, all adopts on main muscle and rules, then carry out colligation or welding after all the other reinforcing bars are alignd with groove while generally construction.The method has several shortcomings: reinforcing bar location, line, colligation need labour more, generally needs 3 people to work above simultaneously; Line only can spacer bars mutual spacing, cannot ensure that main muscle is positioned at same plane, when operation, still need other auxiliary positioning reinforcing bar; , all aim at by naked eyes, still there is error in location when line the location.
Summary of the invention
The purpose of this utility model is to provide a kind of making simply, easy to operate, the auxiliary locator of the steel bar plane spacing that can arbitrarily regulate.
For reaching above object, the utility model takes following technical scheme to be achieved:
A kind of reinforcing bar auxiliary locator, it is characterized in that, comprise many can interconnective screw rod, at least a pair of positioning disk is threaded on every screw rod, this positioning disk comprises the internal thread mating with screw flight and the ring-type firm offer body that extends to outer rim from this internal thread, these firm offer body both ends of the surface are symmetrical arranged half U type groove, two positioning disks axially relatively after, half U type groove between two adjacent firm offer bodies forms a complete U-shaped groove; On end face in firm offer body both sides near outer rim, have the pin-and-hole of perforation, so that alignment pin inserts wherein.
In such scheme, described screw front end is provided with the preceding thread that is less than screw diameter, is provided with the rear thread mating with preceding thread in screw rod tail end, interconnects end to end thereby realize many screw rods.
The recess dimensions of described positioning disk half U type groove is 4～12.5mm, thereby can form the U-shaped groove that groove width is 8～25mm plurality of specifications while making two positioning disks relative, to adapt to the location of different-diameter reinforcing bar.The external edge of described firm offer is provided with circular arc chamfering.
Compare existing construction method, the utility model has the advantages that:
1, can locate by people's complete independently reinforcing bar, save labour;
2, reinforcing bar location spacing is consistent, and installation accuracy is high;
3, can make reinforcing bar all be positioned at same plane, reinforcing bar location total quality is excellent;
4, device is made simply, and easy to operate, cost performance is high.

In Fig. 1～Fig. 3: 1, screw rod; 2, positioning disk; 3, reinforcing bar; 4, alignment pin; 1-1, preceding thread; 1-2, external screw thread; 1-3, rear thread; 2-1, circular arc chamfering; 2-2, pin-and-hole; 2-3, positioning disk internal thread; 2-4, half U type groove; 2-5, firm offer body.
Detailed description of the invention
With reference to figure 1～Fig. 2, the utility model comprises screw rod 1, positioning disk 2, alignment pin 4.Screw rod is hollow tube, and surface is provided with external screw thread 1-2, and screw front end is provided with preceding thread 1-1, and screw rod tail end is provided with rear thread 1-3, and preceding thread mates with rear thread, and preceding thread screws in rear thread can make many screw rods be connected to each other (Fig. 3).Positioning disk comprises the internal thread 2-3 on endoporus and extends to the ring-type firm offer body 2-5 of outer rim from endoporus, these firm offer body both ends of the surface are symmetrical arranged half U type groove 2-4, two positioning disks axially relatively after, the half U type groove between two adjacent firm offer bodies forms a complete U-shaped groove (Fig. 3); The external edge of firm offer is provided with circular arc chamfering 2-1, can conveniently implant reinforcing bar.The pin-and-hole 2-2 that has perforation on end face in firm offer body both sides near outer rim, fixes reinforcing bar so that alignment pin 4 inserts wherein; External thread of screw 1-2 can mate with this internal thread, can make screw rod easily screw in positioning disk.
The utility model positioning function screws in screw rod 1 with reference to 3, two positioning disks 2 of figure, and positioning disk is tightened mutually, fixed what a position; Increase a screw rod, its preceding thread is screwed in to the rear thread of last screw rod, make screw rod spreading; Again another two positioning disks 2 are screwed in to this screw rod, adjust after distance, positioning disk is tightened mutually, so far complete a location spacing; Reinforcing bar 3 is inserted in U-shaped groove, alignment pin 4 is inserted to the pin-and-hole 2-2 corresponding with bar diameter, can make reinforcing bar planar locate.
Adopt the utility model, according to construction needs, by adding long bolt and increasing positioning disk, can form multiple location spacing.Be respectively the positioning U type groove of 8mm, 10mmm, 12mm, 14mm, 16mm, 18mm, 20mm, 25mm by changing the large I formation diameter of positioning disk 2 diameter thickness and half U type groove 2-4 thereof.Pin-and-hole 2-2 can be 8mm, 10mmm, 12mm, 14mm, 16mm, 18mm, 20mm, 25mm corresponding to U-shaped groove bottom vertical distance.
