Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a fixture for fixing vertical bars in concrete wall joints.

(Conventional technology) Conventionally, the vertical reinforcement at the top of the concrete wall joint extends upward by the length of the anchorage, but special consideration is usually given to the method of fixing the reinforcement to ensure the concrete cover thickness. was not paid.

(Problem to be solved by the invention) For this reason, rusting of the reinforcing bars and peeling of the concrete covering may occur due to insufficient concrete cover thickness, and there is a need to improve the accuracy of the cover thickness of the vertical reinforcements. The reality is that there are.

(Means for Solving the Problems) The present invention was proposed to solve the above problems, and consists of a pair of vertical wall bars on the left and right sides of a horizontal rod fixed to an external formwork fixture. This invention relates to a wall longitudinal reinforcement fixing device characterized in that a wall longitudinal reinforcement fixing member having a recessed groove for locking a clamping ruler reinforcing bar is slidably mounted.

(Function) Since the present invention is constructed as described above,
Along the horizontal rod fixed to the external formwork fixture attached to the external formwork, slide the wall vertical reinforcement fixing piece to a predetermined position corresponding to the wall thickness, and then By inserting ruler reinforcing bars into the pair of locking grooves and sandwiching the wall vertical reinforcements, the wall vertical reinforcements can be accurately fixed in a predetermined position.

Therefore, the accuracy of the concrete cover thickness of the wall vertical reinforcement is ensured, and there is no need to manage the cover thickness during concrete pouring.

Further, after the wall concrete is poured, the ruler reinforcing bars are removed and used together with the vertical reinforcement fixing part of the present invention for the construction of the upper floor.

(Example) The present invention will be described below with reference to the illustrated embodiments.

Reference numeral 1 denotes a gate-shaped external formwork fixture, on one side of which a screw rod 2 for tightening is screwed.

One end of a horizontal rod 3 is welded to the top piece of the fixture 1, and the wall vertical reinforcement fixing piece A slides in a cursor style on the horizontal rod 3 that projects in a cantilevered manner from the side of the fixture 1. It is mounted freely.

The fixed piece A is slidably fitted into the horizontal rod 3, and is a cylindrical movable piece 5 onto which the fixing screw rod 4 is screwed.
A vertical piece 6 having a pair of left and right locking grooves 6a, 6a is vertically disposed on the top. Note that 7 in the figure is a stopper provided at the end of the horizontal rod 3 to prevent the fixing piece A from coming off.

Since the illustrated embodiment is constructed as described above, the fixing piece A is slid along the horizontal rod 3 to a position where the normal cover thickness t can be obtained, and the screw rod 4
A plurality of wall reinforcement fixing devices, each having a fixing piece A fixed at a predetermined position on the horizontal rod 3, are arranged along the external formwork P, and each wall reinforcement fixing device is The fixtures 1 are respectively engaged with the upper ends of the external formwork P, and tightened and fixed with the tightening screws 2. Ruler reinforcing bar C spanning between the pair of locking grooves 6a, 6a
, and clamp and fix the wall vertical reinforcement B with the same pair of ruler reinforcing bars C.

After the wall vertical reinforcement B is accurately fixed at a position where the regular cover thickness can be obtained, concrete R is poured between the external formwork P and the internal formwork Q, and then the ruler reinforcement C is removed and the wall Converted to the upper floor with muscle fixing equipment.

(Effect of the invention) In the present invention, the wall vertical reinforcement fixing piece is slid to a predetermined position along the horizontal rod fixed to the external formwork fixture that is attached to the external formwork, and the wall reinforcement fixing piece is attached to the fixing piece. By engaging the ruler reinforcing bars in the recessed grooves for locking the reinforcing bars, the wall longitudinal reinforcing bars are accurately fixed in the specified position, and an accurate concrete cover thickness can be obtained. The structure is simple and easy to set and remove, and the effort required to ensure the thickness of the wall longitudinal reinforcement is greatly reduced. In addition, since the wall vertical reinforcement fixing piece is slidably mounted along the horizontal rod,
It can handle changes in wall thickness and does not require management of cover thickness during concrete pouring.

Furthermore, there is no need to bundle the ruler reinforcing bars for fixing the wall vertical reinforcements, and the ruler reinforcing bars can be used for other purposes together with the fixture according to the present invention.
