JPH0712434Y2 - Anchor bolt support fittings for foundation concrete in construction - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an anchor bolt support fitting used when burying an anchor bolt in ready-mixed concrete in a template for constructing a cloth foundation in construction. .

[Conventional technology]

Conventionally, when constructing a cloth foundation, after filling ready-mixed concrete between the left and right templates, the upper end of each anchor bolt for coupling with the base is projected for a predetermined length at each required interval on the upper surface of the concrete. The lower part was inserted and fixed by solidifying concrete.

[Problems to be solved by the device]

However, in the process of drying and solidifying the fresh concrete, the bolt gradually settles down due to the condensation of the structure and the weight of the bolt. was there.

[Means for Solving the Problems]

In order to eliminate the disadvantages of the present invention, the upper end of each anchor bolt planted in the ready-mixed concrete between the template plates is gripped by the support rod hooks hung on the template to fix the anchor bolts. The bolt is prevented from sinking and the upper end portion of the bolt is always fixed in a protruding state by a required length.

That is, on the side surface of the middle part of the long support rod, the acupressure portion that applies acupressure against its own resilience or an ammunition, and by acupressure or decompressing the acupressure portion, the side surface of the support rod is elastically separated or approached. A grip having a gripping part is provided.

[Action effect]

Since this plan is configured as described above, the upper ends of the anchor bolts are projected at a required length on the upper surface of the ready-mixed concrete filled between the left and right mold plates, the lower part is inserted, and then the upper ends are hooked between the mold plates. When the concrete is dried up by holding it on the rack of the support bracket, the clamp bolt is expanded by acupressure, and the support bracket is removed.After removing the template, the anchor bolt has the required length on the concrete foundation. It is fixed in a protruding state.

Since the present invention is as described above, since the anchor bolt is supported by the support metal fitting at its upper end and is fixed together with the solidification of concrete, the anchor bolt may be settled in the process leading to the dry solidification of the fresh concrete as described above. Therefore, since the anchor bolt can always be fixed to the concrete upper surface in a required length in a protruding state, there is no fear that the anchor bolt and the base cannot be coupled. However, the support of the anchor bolt using the support bracket of the present invention can be performed simply by pressing and depressing the acupressure part of the knob, and further, there is an advantage that the protrusion length can be easily adjusted. It has ingredients.

〔Example〕

(1) A grip 2 is formed by inserting a grip 2 having a vertical groove H in the middle side surface of the elongated support rod 1 and made of a band-like elastic plate D having an S-shaped flat surface from the groove. A small bent portion γ serving as Y is projected to the outside of the support rod 1, and a base end of a large bent portion R serving as an inner acupressure portion F is fixed to the inside of the supporting rod. Anchor bolts, 4 are templates, and 5 is concrete.

(2) Inside the middle part of the elongated support rod 1, a base end of a band-shaped elastic plate D that is bent in a planar shape is fixed P, and the base end is bent outward at the tip thereof to form an acupressure part F. In addition, the inside of the gripping portion of the band-shaped clip 2 having the gripping portion Y formed by slightly bending the tip is superposed and fixed P.

(3) The substrate E of the bearing piece L is fixedly attached P to the inside of the substantially middle portion of the elongated support rod 1, and the bearing piece is bent at a finger-pressure portion F at the rear end and bent at a right angle to the tip and slightly bent γ. A straddle piece W formed by bending is formed on the inner surface of the middle portion of the grip 2 having a grip portion Y, and a shaft g on which a spiral ammunition is fitted is skewed between these bearing pieces. It is a thing.

(4) One end of a short strip-shaped elastic plate D formed in a substantially W-shape in a plane is fixed to the inside P of the elongated support rod 1 at one end, and the tip of the elastic plate is picked at the other end. Y, and the base end of the knob 2 having the acupressure part F as the rear end is superposed and fixed P.
