Description

Connecting tool of corner of reinforcing for bent}

The present invention relates to a tool for connecting corners of pier reinforcement, and more particularly, to facilitate connection of secondary reinforcement to a large square pier, so that seismic work can be maintained while maintaining sufficient rigidity with ease of reinforcement work. .

Generally, piers are divided into circular and rectangular ones. Circular piers are mainly used for small and medium piers, and rectangular piers are used for medium and large piers.

As described above, the reinforcing bar used in the medium-large pier is to use a reinforcing bar having a considerably larger diameter in consideration of the load that the pier must bear, the seismic design load, and the like. It is also divided into secondary reinforcing bars in a right angle to maintain a constant interval.

If the price of the main reinforcing bar and auxiliary reinforcing bar is high, and it is loaded and stored on site, it is impossible to bend and cut it on site due to fear of loss and loss. The rebar is manufactured and supplied.

It is a means for connecting both ends of auxiliary reinforcing bars by making one turn in the direction perpendicular to the main reinforcing bars that are reinforced in the longitudinal direction of the piers because it is processed and supplied at a place away from the site as described above. Rebar joints are used.

When the reinforcing bar is used, if the length of the reinforcing bar is short within the error range that the reinforcing bar can cover, there is no problem. However, if the reinforcing bar has a shorter length than the error range, the reinforcing bar can be reinforced using the reinforcing bar. The problem arises.

Therefore, the present invention is designed to solve the problems as described above by making it easier to reinforce the secondary reinforcing bars in the right angle direction of the main reinforcement of the piers constructed in a rectangular seismic construction, but also to easily respond to changes in the length of the secondary reinforcing bars The main purpose is to provide the ease of construction of auxiliary rebar.

Explain.

Main bars are reinforced to maintain a constant interval in the longitudinal direction of the pier 30 in order to form the pier 30, and the equal intervals are maintained in a band shape at right angles to the main bars 31 and 32. It is constructed by placing concrete 35 inside and outside of the secondary reinforcing bars 33 and 34 to be placed.

In the present invention, by providing a corner heat tool 40 that can be applied to the corner portion of the secondary reinforcing bars (33, 34) to the main reinforcing bars (31, 32) irrespective of the length of the secondary reinforcing bars (33, 34) It is characterized by connecting and reinforcement.

The corner connecting tool 40 has a suitable round 41 so that the central portion can be connected to the main reinforcing bar 31, which is placed at the corner of the pier 30, the auxiliary reinforcing bars 33 and 34 can be accommodated sufficiently. A pipe having a bore having an inner diameter is bent to have a roughly b-shaped tool body 42.

Both sides of the tool body 42 are provided with reinforcing bars 45 which can clamp and clamp both ends of the auxiliary reinforcing bars 33 and 34.

The reinforcing bar 45 is formed with a screw 47 in the inner diameter to be coupled to the screw 46 formed on both ends of the tool body 42, the outer diameter and the knurling that can provide ease of coupling and A holding tube 49 having the same friction means 48 is provided.

The inner diameter of the holding tube 49 is provided with a screw 50 on the outer diameter, and the inner diameter is provided with an intermittent tube 51 which is reduced in diameter toward the front side, and the inner diameter of the intermittent tube 51 has an auxiliary reinforcement 33, A pair of clamps 54 and 55 in which an interruption groove 53 is formed to intercept the nodes 52 formed in the 34 are provided.

A locking jaw 56 is formed at the inner diameter end of the intermittent tube 51 to prevent separation of the clamps 54 and 55, and the clamps 54 and 55 are directed toward the front side as the intermittent tube 51. It is preferable to comprise in the form which shrinks a diameter.

The present invention as described above,

When reinforcing the auxiliary reinforcing bars (33, 34) with respect to the main reinforcing bars (31, 32), the auxiliary reinforcing bars (33, 34) are provided only as long as the length of the straight part except the corner part of the straight part, the corner part of the piers (30) The corner connecting tool 40 is connected to each of the auxiliary reinforcing bars 33 and 34 provided in a straight line to be arranged.

Looking at this, the intermittent groove formed in the clamp (54, 55) by inserting the clamping pipe (51) in the auxiliary reinforcing bars (33, 34) and then close the clamp (54, 55) to both ends of the auxiliary reinforcing bars (33, 34) The clamps 54 and 55 are moved to the reinforcing bar 33 by strongly moving the intermittent pipe 51 in the direction of the clamps 54 and 55 with the nodes 52 of the auxiliary bars 33 and 34 positioned at the 53. , 34).

Since the diameter of the clamps 54 and 55 and the intermittent pipe 51 decreases toward the front side, both ends of the auxiliary reinforcing bars 33 and 34 are secured by the clamps 54 and 55 and the intermittent pipe 51. It becomes a state of being interrupted.

In this state, the intermittent pipe 51 is screwed to the retaining pipe 49, and then the Newage pipe 49 is screwed to both ends of the tool body 42 to complete the reinforcement of the auxiliary reinforcing bars 33 and 34.

When the auxiliary reinforcing bars (33, 34) as described above, even if the length of the straight portion of the auxiliary reinforcing bars (33, 34) is slightly longer or shorter, the coupling state of the retaining pipe 49 and the intermittent pipe 51 is maintained. You just need to adjust the length to respond.

The present invention as described above makes it easier to reinforce and connect auxiliary reinforcement in the rectangular direction of the rectangular pier main reinforcing bar to be earthquake-resistant, and to easily cope with the change in the length of the auxiliary reinforcement processed and supplied at the site and other places. Various effects can be obtained, such as ease of construction.
