Abstract

(57) [Summary] [Object] To provide a construction spacer that can be easily attached to the intersection of a floor reinforcement and a beam reinforcement assembled to a floor formwork, and that can reliably maintain the floor thickness and the horizontal level of the floor surface. . [Constitution] In order to be attached to the intersection of a vertical line and a horizontal line, a reference bar for securely maintaining the floor thickness and the horizontal level is provided integrally at an appropriate position of a fixing member formed in a cross shape.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a construction spacer for maintaining a floor thickness and a floor level in a case where a floor is mainly constructed of a concrete structure.

[0002]

[Prior art]

 In this type of conventional construction spacer, a reinforcing bar is vertically welded to a vertical bar and a horizontal bar, or a reinforcing bar or a bar is fixed by a binding wire, and when used for welding, the strength of the structure is reduced. In addition, if a reinforcing bar or rod is fixed with a binding wire, it is unstable and difficult to fix. In addition, the steel bars cut to the length of the floor thickness are welded vertically to the vertical bars and the horizontal bars and attached, but this requires a lot of work.

[0003]

[Issues to be solved by the invention]

 The present invention has been made in view of the above problems, and its purpose is to easily attach it to the intersection of a floor reinforcement assembled on a floor formwork and to minimize structural defects in a concrete section. Another object of the present invention is to provide a construction spacer capable of securely maintaining the floor thickness and the floor level.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned object, the present invention integrally provides a support bar having a length equal to or greater than the floor thickness at an appropriate position of a cross-shaped fixing device to be attached to an intersection of a vertical line and a horizontal line.

[0005]

[Example of the invention]

 The construction spacer of the present invention is first fitted with a fixture at the intersection of the floor streaks and bent at four protruding portions. In this state, the support rods have already been projected in the vertical direction, and the floor thickness and the horizontal level of the floor surface can be accurately secured by marking the support rods with the floor thickness and level.

[0006]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1 is a construction spacer. Numeral 2 denotes a fixture, in which a concave vertical streak fixing portion 2a formed by bending a flat plate into a substantially L-shape and a horizontal streak fixing portion 2b are integrally formed in a cross shape so as to be fixed to the vertical streak. Reference numeral 3 denotes a support bar provided with a sponge 3a at the end having a support bar having a length equal to or longer than the floor thickness in the vertical direction at the intersection of the vertical streak fixing portion and the horizontal streak fixing portion 2b.

As an example of use of this embodiment, as shown in FIG. 2, a vertical streak fixing portion 2a is attached to a vertical streak A at an intersection of a floor streak C composed of a vertical streak A and a horizontal streak B arranged in advance. B is fitted with the lateral muscle fixing portion 2b appropriately, and the protrusion is bent and attached to the floor muscle C. In this state, the floor thickness and the horizontal level can be accurately secured by marking the floor thickness and the horizontal level on the support bar 3 protruding in the vertical direction.

[0008] The length of the support rod is changed depending on the floor thickness. Further, the vertical streak fixing portion and the horizontal streak fixing portion have a shape that can be used not only for the outer diameter of the vertical streak and the horizontal streak.

[0009]

[Effect of the invention]

 This device can be easily installed at the intersection of the floor reinforcement assembled on the floor formwork by the above configuration, and the floor thickness and the horizontal level of the floor surface can be accurately secured by marking the floor thickness and the horizontal level Things.
