Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to an anchor plate mounting bracket for concrete construction for mounting an anchor plate used for erection of steel frame columns of a concrete structure to a vertical bar. is there.

(Prior Art) Conventionally, in order to attach this type of anchor plate for concrete construction to a vertical bar, as shown in FIG. 5, a predetermined height of a required vertical bar (a) protruding upward from a concrete foundation is provided. The U-shaped metal fittings (b) are fitted in the respective positions and fixedly fixed, and the flat bar (d) on which the anchor plate (c) is placed is welded to the U-shaped metal fittings (b).

Next, the anchor plate (c) is placed in close contact with the flat bar (d), and then the position of the anchor plate (c) in the height direction, the inclination of the anchor plate (c), etc. are adjusted and the anchor plate (c) is adjusted. ) Is welded to the flat bar (d).

(Problems to be Solved by the Invention) In the above-mentioned conventional anchor plate mounting device for concrete construction, (a) the material of the flat bar on which the anchor plate is mounted is required.

(B) After the anchor plate is placed on the flat bar, it is difficult to perform positioning by finely adjusting the position of the anchor plate in the height direction, the inclination of the anchor plate, and the like, and much work is required for the work.

(C) Since the U-shaped metal fitting is fitted into the vertical streak and fixed tightly, a U-shaped metal fitting corresponding to the thickness of the vertical streak must be prepared.

 There is a problem in such points.

(Means for Solving Problems) In order to solve the above-mentioned problems, the present invention has a vertical stirrup (A) with a U-shaped metal (1) having a fitting portion detachable from the side. Bearings (2), (2) are provided, and an adjusting bolt (4) with an operating section (3) is rotatably fitted between the upper and lower bearings (2), (2) to adjust the adjusting bolt (4). To the base plate screw hole of the receiving piece (5) of the anchor plate (B), and screw the tightening bolt (7) from the outside into the screw hole (6) communicating with the fitting part of the U-shaped metal (1). To construct the anchor plate mounting bracket (a) for concrete construction.

(Operation) At a predetermined height position of the required four vertical streaks (A) protruding on the concrete foundation, the left and right mounting brackets (a), the receiving pieces (5), (5) of the (a) are attached. The fitting portions of the U-shaped metal (1) of the mounting bracket (a) are fitted to the vertical bars (A) from the sides so as to face each other, and the tightening bolts (7) are tightened to the vertical bars (A) to vertically Fix the mounting bracket (a) to the streaks (A). Next, after placing the anchor plate (B) on the four receiving pieces (5), the adjusting bolt (4) is appropriately rotated by the operating portion (3) and screwed onto the adjusting bolt (4). The received receiving piece (5) is adjusted up and down to adjust the position of the anchor plate (B) in the height direction and the levelness of the anchor plate (B), and the anchor plate (B) is positioned.

Then, each receiving piece (5) and the anchor plate (B) are appropriately fixed by welding or the like.

(Embodiment) The structure of one embodiment of the present invention shown in FIGS. 1 to 4 will be described. (A) shows an anchor plate mounting bracket for concrete construction, and (1) shows an anchor plate mounting bracket ( a) U-shaped gold in the vertical direction, the bearing (2) is attached to the upper and lower ends of the outer surface of one side of the U-shaped gold (1),
(2) is provided so that the tightening bolts (7) are screwed from the outside into the screw holes (6) above and below the other side piece. (4) is an adjusting bolt having an operating head (3) at its upper end, which is used for the bearing (2),
The adjustment bolt (4) is inserted into (2), the lock nut (8) is screwed into the downward protruding portion of the adjustment bolt (4), and the adjustment bolt (4) is rotatably fitted to the bearings (2) and (2). Reference numeral (5) is a receiving piece, which is concentric with the base through hole (9) and has a nut (10) fixed to the lower side thereof to provide a screw hole for the base portion, and the receiving piece (5) is provided at an intermediate portion of the adjusting bolt (4). The anchor plate fitting (a) is constructed by loosely fitting the through hole (9) and screwing the nut (10).

(A) is a vertical bar of deformed reinforcing bars protruding upward from the concrete foundation, and (B) is an anchor plate.

Next, the operation will be described. At the position where the steel structure columns of the concrete structure are erected, the left and right mounting brackets (a), (a) are placed at the predetermined heights of the required four vertical bars (A) as shown in FIG. The receiving pieces (5) and (5) of the above are made to face each other, and are attached to the vertical streaks (A) from the side, respectively, by the mounting bracket (a).
After fitting the fitting portion of the U-shaped metal (1), the upper and lower tightening bolts (7) are tightened to the vertical bar (A) as shown in FIG. ) Is fixed.

Next, after placing the anchor plate (B) on the four receiving pieces (5), rotate the adjusting bolt (4) with the operating head (3) and screw it to the adjusting bolt (4). Adjusting the combined receiving piece (5) up and down, the position of the anchor plate (B) in the height direction and the anchor plate (B)
Of the anchor plate (B)
Adjust the front, rear, left, and right to position.

When the anchor plate (B) reaches a predetermined position, the lock nut (8) is tightened to the lower bearing (2), and then,
Each receiving piece (5) and the anchor plate (B) are appropriately fixed by welding or the like.

After that, although not shown, the anchor plate (B)
Place concrete up to the bottom surface of.

After the concrete has hardened, the required number of mounting bolts are erected at predetermined positions on the anchor plate (B) by welding or the like, and the through holes of the support steel frame are fitted into the mounting bolts. The substrate is placed on the anchor plate (B). After that, a nut is screwed on the upper protruding portion of the mounting bolt, and the support steel frame is installed on the anchor plate (B).

(Effect of the Invention) The anchor plate mounting bracket for concrete construction of the present invention has the following remarkable effects.

(1) Fit the U-shaped gold fitting part of the mounting bracket to the vertical line from the side and tighten the fixing bolts to secure the mounting bracket.

Therefore, (a) it is easy to attach the mounting bracket to any position of the vertical streak for the one-touch attachment.

(B) It is convenient for work and handling because it can be applied regardless of the thickness of the vertical streaks.

(2) Since the anchor plate can be placed directly on the receiving piece of the mounting member, the material can be saved without the need for a conventional flat bar, and one step of mounting the flat bar can be omitted.

(3) After placing the anchor plate on the receiving piece, adjust the anchor plate by appropriately rotating the adjusting bolt by the operating portion to move the receiving piece up and down.

Therefore, (b) fine adjustment of the anchor plate in the height direction can be easily and smoothly performed to improve work efficiency.

(B) The position of the anchor plate in the height direction and the levelness of the anchor plate can be adjusted quickly and accurately.

(C) The anchor plate is securely supported.

(4) Simple and compact, easy and inexpensive to manufacture and easy to handle.
