Rebar Couplers In Accordance With National Building Codes

Generally relates to Rebar Couplers and connecting means for connecting a pair of concrete reinforcing ribs adjacent to each other with the same or different size. The present invention relates to improvements in the connection mechanism between the connector and the reinforcing bar, and more particularly to the greater economic value of the reinforcement link method. Other applications of the present invention are another method for connecting a pair of threaded rebars.

Reinforcement is reinforced by hot rolling. When the steel bars are rounded, they are called round bars. When the rolled out of the bar in its longitudinal surface with ribbed text is called deformation of steel. The ribbed pattern is designed to facilitate the anchoring of the reinforcement and the surrounding material such as concrete. The ribbed design is subject to national building codes. The ribbed ribs are generally composed of two series or more parallel transverse ribs. The two parallel transverse ribbed series have the same inclination or opposite angles to each other. In addition, each series of horizontal ribs should have a substantially uniform spacing.

During the hot rolling process, ribbed lines are formed on the final rolling unit. Each series of transverse ribs is usually formed by rolled ribbed grating. And each roll is rolled independently of each other. In other words, even if the horizontal ribs in each series have a predetermined angle and spacing, the transverse ribbed series rolls on each side of the reinforcing bar) are arranged arbitrarily with respect to each other. Therefore, even if the deformed steel ribs have the same ribbed pattern, if there are different production batches of manufacturing will have different horizontal ribbed arrangement.

The connection between two adjacent Rebar Couplers can be divided into the following three categories: 1) Lap the two connecting bars with the appropriate length, passing enough force from one of the bars through the surrounding concrete to the other The

2) Lap welding Two connecting bars, in which case the lap length is shorter than the category 1 because the rebar can transmit force directly through the welded part.

A type of reinforced reinforcing bar connector with a standard deformation pattern rolled. The connector is for connecting the end of the rebar end to the end of the bar, which comprises at least one clamping device, the fastening means comprising at least one pair of chucks mounted in the hollow tube having at least two longitudinal gaps. The inner circumferential surface of the fastening device is substantially conformed to the outer peripheral surface shape of the reinforcing bar and also forms an inner groove which cooperates with the deformation pattern of the reinforcing bar, whereby when the fastening means approaches the inner circumference of the reinforcing bar, The outer surface of the fastener means comprises at least one tapered threaded threaded end portion which is engageable with the fastening nut The The inner surface of the fastening nut is tapered and threaded to fit the outer surface of the fastening device. In this way, when the fastening nut rotates the fastening means, the tapered end of the fastening means will move toward the small perimeter portion of the fastening nut so that the longitudinal gap between the chucks approaches and closes, Rebar Couplers The head is in close contact with the outer peripheral surface of the reinforcing bar. The invention provides and provides the use of a connector according to the invention for end-to-end connection of two rebars.

A connector is provided for connecting a type of reinforcing bar with a standard deformation pattern to an object. The connector comprises at least one clamping device, the fastening means comprising at least one pair of chucks mounted in the hollow tube having at least two longitudinal gaps. The inner circumferential surface formed by the fastening means cooperates with the outer peripheral surface shape of the reinforcing bar, and the fastening means has an inner groove which cooperates with the deformation pattern of the reinforcing bar. Whereby the inner circumferential surface of the reinforcing bar will be in contact with the outer peripheral surface of the reinforcing bar when the fastening means is close to the reinforcing bar, and the deformed pattern of the reinforcing bar will be placed in the inner groove of the fastening means, The surface comprises at least one tapered threaded threaded end that can engage the fastening nut. The inner surface of the fastening nut is tapered and threaded to fit the outer surface of the fastening device. So that when the fastening nut rotates the clamping fastener,Rebar Couplers the tapered end of the fastening means will move toward the small perimeter of the fastening nut so that the longitudinal gap between the chucks approaches and closes, The head is in close contact with the outer peripheral surface of the reinforcing bar.
