Description
Technical Field
The utility model belongs to the technical field of the assembly type structure device and specifically relates to an assembly type structure reinforcing bar dry-type connecting device.
Background
At present, more and more concrete fabricated buildings are put into building construction, and the characteristics of green, environmental protection, low carbon and the like enable the concrete fabricated buildings to be well applied. The concrete assembled components are assembled by being transported to the site after being processed and finished in a factory, and part of steel bars can be reserved in the components to be exposed outside, so that the components can be conveniently connected. In the work of maintaining and reforming the reinforcing steel bars embedded into concrete and connecting bent reinforcing steel bars in a building structure, the prior domestic technology is mainly realized by using a grouting sleeve, and the Chinese utility model patent with the patent publication number of CN208088668U discloses 'a full grouting sleeve for reinforcing steel bar connection', and the technical scheme of the invention is as follows: the grouting sleeve comprises a first grouting sleeve and a second grouting sleeve, wherein the first grouting sleeve and the second grouting sleeve are connected through threads in a screwed mode, a grouting hole is formed in the first sleeve, a grout discharging hole is formed in the second sleeve, and the two grouting sleeves are fixedly connected with connected reinforcing steel bars through grouting materials in the grouting sleeves.
The existing grouting sleeve connection mode is complex in process, strict in construction environment requirement, high in operation technology difficulty, large in factor influence and capable of bringing certain difficulty to construction.
The utility model discloses the dry-type connecting device of the grout formula of exempting from of well adoption can adapt to various construction environment, can reliably, swift the connection with the reinforcing bar that has imbedded in the concrete, and the reinforcing bar need not to carry out earlier stage treatment, and convenient operation saves time.
SUMMERY OF THE UTILITY MODEL
Big, the influence factor is many, the difficult scheduling problem of operating technique in order to solve the operation degree of difficulty of reinforcing bar traditional connected mode, time when saving the steel bar connection improves steel bar connection's quality, the utility model provides an assembly type construction steel bar dry-type connecting device can effectively guarantee steel bar connection's quality, saves operating time.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides an assembly type construction steel bar dry-type connecting device, by reinforcing bar main part, sleeve, jackscrew, short screw post, long screw post, hand twist formula screwed pipe constitute, short screw post and long screw post all set up in the one end that the sleeve diameter is big, the jackscrew is twisted in the screwed hole at sleeve middle part, hand twist formula screwed pipe sets up on long screw post, in the reinforcing bar main part inserted the sleeve, screw up the jackscrew alright fix the reinforcing bar main part, every side of jackscrew arranges two.
Preferably, the sleeve is formed by integral casting, is made of aluminum-magnesium alloy, is internally processed into a rough surface, has the end with the small diameter of the section of the sleeve larger than the diameter of the steel bar main body by 2mm and has two specifications of 16mm and 18mm, and the inner roughness can increase the friction force to a certain extent.
Preferably, the screw holes are provided at both sides of the sleeve, two on each side, and aligned along the central axis.
Preferably, the jackscrew is a screw made of steel material and has a length of 0.5cm, and one jackscrew is screwed into each screw hole to fix the steel bar body through extrusion force.
Preferably, the hand-screwed threaded pipe is made of aluminum-magnesium alloy and can be screwed clockwise and anticlockwise, the short screw column and the long screw column are aligned, and the hand-screwed threaded pipe can be connected together at the interface of the hand-screwed threaded pipe and the long screw column through screwing, so that the purpose of dry connection is achieved.
The utility model has the advantages that: (1) the concrete assembling type concrete connecting device has the advantages that steel bars in the concrete assembling type concrete are effectively connected, the connecting quality is guaranteed (2), the construction time can be saved to a greater extent, the mounting and the connection are quicker and simpler, the applicability is wide (3), and a safer, more reliable and quicker connecting technology is provided for steel bar connection in the assembling type industry.
