Abstract
The utility model relates to a connecting device for steel bars, which comprises a metal sleeve barrel, wherein, the end part of the metal sleeve barrel is provided with tapered internal threads, a formed taper thread hole has a small diameter near the inner side of the metal sleeve barrel and a large diameter near the outer side of the metal sleeve barrel, the cone angle of the formed taper thread hole is 3 DEG, the thread pitch of the internal threads is 2.5 mm, and the end part provided with the tapered internal threads is connected with steel bars cut external threads having the same specifications as the internal threads. Due to the adoption of the specific cone angle and the thread pitch, the connecting strength of the connecting device of the utility model is enhanced greatly.
Description
The utility model relates to a kind of reinforcing bar connector, and it is used for the connection of building operations reinforcing bar.
At present, owing to developing rapidly of domestic economy, living standards of the people improve day by day, and urban population is intensive, and building land more and more lacks, so highrise building rolls up thereupon.But the inside of high-rise building need be provided with a large amount of reinforcing bars, and to form firm steel work, building is high more, and its difficulty of construction is big more.The basic charge that the reinforcing bar of highrise building sets up accounts for high ratio in whole engineering cost, so people wish that the connection of reinforcing bar is simple and convenient.
At present, general connecting method for reinforcing bars comprises colligation overlap joint and welding in the building operations, and is low through the reinforced steel bar strength of colligation overlap joint, and expends great amount of manpower and material resources, and the electric welding connecting reinforcement engineering time is long, energy consumption is high, and can produce secondary stress to reinforcing bar.People have proposed multiple novel reinforcing bar connector for this reason, but all there is the low shortcoming of bonding strength in these connectors.
The purpose of this utility model is to provide a kind of reinforcing bar connector, and this reinforcing bar connector can improve the bonding strength of reinforcing bar greatly, and it is quick and convenient that reinforcing bar is connected.
Above-mentioned purpose of the present utility model is to realize by the reinforcing bar connector of following structure, this reinforcing bar connector comprises metal sleeve, its end is provided with conical internal thread, formed taper thread hole is little near the diameter of metal sleeve inboard, and it is big near the diameter in the metal sleeve outside, its cone angle is that the pitch of 3 ° of internal threads is 2.5mm, and the above-mentioned end that is provided with conical internal thread has the externally threaded reinforcing bar of same specification to be connected with cutting.
Another characteristics of the present utility model are above-mentioned metal sleeve one end opening one end sealing, this blind end is used for being connected with steel work in the building, above-mentioned conical internal thread then is arranged on the openend of metal sleeve, thereby this open end can have the externally threaded reinforcing bar of same specification to be connected with cutting.
Characteristics more of the present utility model are that above-mentioned metal sleeve two ends are opening, and two openends of this metal sleeve are equipped with the conical internal thread of above-mentioned specification, thereby can have the externally threaded reinforcing bar of same specification to be connected with cutting respectively.
Advantage of the present utility model is because selected specific tapering and pitch can make bonding strength improve 0.3-0.5 doubly, and connect rapid, easy to operate, good to neutrality, weatherproof, safe and reliable.
When the utility model was used for the connecting thread reinforcing bar, each joint only need improve 9 times of work efficiency than the welding of electric arc overlap joint with 1 minute time, improves 10 times of work efficiency than the air pressure welding, improves 4 times of work efficiency than the electroslag welding.Compare also with above-mentioned welding method in addition and can save a large amount of energy.Compare with the assembling reinforcement mode and can save great deal of steel, and avoided the difficulty of the placing of concrete that assembling reinforcement caused, but and all-weather construction.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the generalized section of first embodiment of the present utility model;
Fig. 2 is the floor map of second embodiment of the present utility model.
As shown in Figure 1, first embodiment of the present utility model is single head welding shaped steel muscle connector, it comprises metal sleeve (1), the blind end (3) of this metal sleeve (1) be used for building in steel work, weld mutually as deformed steel, i iron, channel-section steel etc., its openend (2) is used for being connected with reinforcing bar, this openend (2) is provided with conical internal thread, the less side of the diameter of formed bellmouth is in the inboard of metal sleeve (1), and the bigger side of diameter is in the outside of the openend (2) of metal sleeve (1).Can be in when construction with the end reinforced conical external screw thread that is processed into above-mentioned conical internal thread same size, thus can be screwed into the openend (2) of metal sleeve (1).
As shown in Figure 2, second embodiment of the present utility model is a GENERAL TYPE reinforcing bar connector, and it can be used for monolateral rotatable reinforcing bar and connects, and it is specially adapted to the connection of reinforcing bar in wall column base plate in the building, the heavy railway carriage or compartment etc., and its scope of application is wider.This connector comprises metal sleeve (1), and it comprises two openends (2), and this openend is provided with conical internal thread, and the shape of this conical internal thread is identical with the internal thread shown in Fig. 1.When construction, available syllogic car tooth machine carries out car dentification taper thread with the end of reinforcing bar to be connected, with spanner connector is connected with reinforcing bar then.Above-mentioned metal sleeve processes positive and negative conical internal thread with the computer program controlled lathe of the CNC of precision at its two ends in advance in factory.
Claims (3)
1, a kind of reinforcing bar connector, it is characterized in that it comprises metal sleeve, its end is provided with conical internal thread, formed taper thread hole is little near the diameter of metal sleeve inboard, and it is big near the diameter in the metal sleeve outside, its tapering is 3 °, and the pitch of internal thread is 2.5mm, and the above-mentioned end that is provided with conical internal thread has the externally threaded reinforcing bar of same specification to be connected with cutting.
2, connector according to claim 1, it is characterized in that above-mentioned metal sleeve one end opening one end sealing, this blind end is used for being connected with steel work in the building, above-mentioned conical internal thread then is arranged on the openend of metal sleeve, thereby this open end can have the external screw thread reinforcing bar of same specification to be connected with cutting.
3, connector according to claim 1, it is characterized in that above-mentioned metal sleeve two ends are opening, two openends of this metal sleeve are equipped with the conical internal thread of above-mentioned specification, thereby can have the externally threaded reinforcing bar of same specification to be connected with cutting respectively.
