Abstract
The utility model relates to an equal intensity connector of steel bar, which is mainly composed of two steel bar joints and a connecting sleeve. The connecting sleeve is a straight thread connecting sleeve. The joints of the two steel bars is processed into a straight thread joint which has the advantages of convenient process and usage, low cost, strong generality, high connecting strength and equal strength with steel bar, etc. Due to the experiment, the bearing capacity of tension can reach more than 1.1 times than the connected steel bar, therefore enhancing the connecting speed of the steel bar and carrying out construction all day long, which is suitable to be used largely for building construction unit.
Description
The utility model relates to a kind of indented bars for building linkage each other, particularly a kind ofly can belong to building material field more than or equal to the connector that is connect reinforcing bar tension bearing capacity.
Need in the concrete structure to make reinforcement with indented bars, the length of reinforcing bar will be decided according to the situation of building, when the length of a reinforcing bar is not enough, just need be connected with another root reinforcing bar, two interconnective modes of reinforcing bar mainly contain the overlap welding formula at present and connect, the butt welding formula connects, the telescopic connection of tapered thread, wherein, the connection of overlap welding formula is connected with the butt welding formula because of being subjected to human factor and current/voltage fluctuation etc. to influence big welding quality and is difficult to guarantee, though the telescopic connection of tapered thread can overcome the shortcoming of above-mentioned welded type, there are shortcomings such as high and being connected when not being suitable for two piece reinforcing bars all can't rotating unequal with reinforced steel bar strength of processing cost with joint.
The purpose of this utility model is in order to overcome the weak point of existing reinforcing bar connector, designs a kind of structure tube list, processing is easy to use, cost of production is lower, strength of joint can be connect with quilt, and reinforcing bar equates and the equal strength connector of the reinforcing bar of highly versatile.
The equal strength connector of reinforcing bar of the present utility model mainly is on the basis of two bar splices and an adapter sleeve, become straight thread to make it to become the straight thread adapter sleeve internal thread machining of adapter sleeve, straight thread is processed in the joint of reinforcing bar makes it to become the straight thread connector.
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing 1 is the straight thread connector of reinforcing bar, the 2nd, and the straight thread adapter sleeve.Described straight thread adapter sleeve should be selected medium carbon steel or high-carbon steel for use, the length of straight thread adapter sleeve is 40-100MM, the external diameter of straight thread adapter sleeve is than the big 10-30MM of diameter of straight thread connector, and the reach of straight thread connector should be greater than bar diameter, and the pitch of straight thread is 1.5-4MM.For example, be the reinforcing bar of 16MM for diameter, the optional 40-50MM of the length of straight thread adapter sleeve, the optional 25-30MM of the external diameter of straight thread adapter sleeve, the optional 20-30MM of the reach of straight thread connector, the optional 1.5-2.5MM of the pitch of straight thread.For diameter is the reinforcing bar of 25MM, the optional 50-70MM of the length of straight thread adapter sleeve, the optional 35-45MM of the external diameter of straight thread adapter sleeve, the optional 30-40MM of the reach of straight thread connector, the optional 2-3MM of the pitch of straight thread.For diameter is the reinforcing bar of 40MM, the optional 80-100MM of the length of straight thread adapter sleeve, the optional 50-70MM of the external diameter of straight thread adapter sleeve, the optional 50-60MM of the reach of straight thread connector, the optional 3-4MM of the pitch of straight thread.During use, with tapping machine the straight thread connector is processed in the joint of reinforcing bar at the construction field (site), prefabricated straight thread adapter sleeve is screwed on the straight thread connector of a reinforcing bar, the straight thread connector of another root reinforcing bar is tightened on the straight thread adapter sleeve get final product again.In the time of all can't rotating as two reinforcing bars, the screw thread of a reinforcing bar can be lengthened to length greater than adapter sleeve, all be screwed in the reinforcing bar of long screw thread with a locking nut and straight thread adapter sleeve then, again the short reinforcing bar collimation of the reach cover that is threaded, reverse rotation straight thread adapter sleeve makes it to enter and tighten on the short steel bar end of screw thread, at last locking nut is also rotated and tighten with the straight thread adapter sleeve to get final product.When connecting as reinforcing bar that will be different with diameter, the corresponding straight thread of straight thread connector that two of straight thread adapter sleeve can be processed into respectively with two reinforcing bars gets final product.
It is easy to use to the utlity model has processing, and production cost is lower, highly versatile, and the bonding strength height, Can with reinforced steel bar strength phase etc. advantage, through test its tensile capacity reach 1.1 times of being connected reinforcing bar with On, can improve the connection speed of reinforcing bar and carry out all-weather construction, be fit to building unit and be extensive use of.
Claims (2)
1. the equal strength connector of a reinforcing bar comprises two bar splices and an adapter sleeve, it is characterized in that adapter sleeve is the straight thread adapter sleeve, and the straight thread connector is processed in the joint of two reinforcing bars.
2. the equal strength connector of reinforcing bar as claimed in claim 1, it is characterized in that the straight thread adapter sleeve selects medium carbon steel or high-carbon steel for use, the length of straight thread adapter sleeve is 40-100MM, the external diameter of straight thread adapter sleeve is than the big 10-30MM of diameter of straight thread connector, the reach of straight thread connector should be greater than bar diameter, and the pitch of straight thread is 1.5-4MM.
