Abstract

The present invention relates to a gap retaining member for fixing a mold when a concrete wall is to be constructed. In the past, the peripheral portion of the fixing hole of the gap retaining member fixed between the molds is damaged by a load, In order to solve this problem, there is provided a mold space holding tool having a fixing part formed on one side thereof with a screw part to be coupled to a connut and a fixing hole formed on the other side thereof with a fixing hole to be fixed to the mold, A forged reinforcing portion 32 is formed at the periphery of the fixing hole 31 formed in the forging reinforcing portion 30 and a plurality of reinforcing belts 33 are protruded and formed on the surface of the forged reinforcing portion 32 To provide a cavity for retaining the mold.
Therefore, according to the present invention, a plurality of reinforcing bands are protruded from the fixing hole of the fixing portion to prevent the rupture and cutting of the peripheral portion of the fixing hole due to the load at the time of construction of the wall surface. As a result, And the corner of the fixing part is formed into a round shape to prevent the worker from being injured or the work clothes being damaged during the work.

Description

Space sustenance for concrete form

More particularly, the present invention relates to a mold for holding a gap for a form, more specifically, to improve rigidity in the periphery of a hole of a fixing portion in which a load is concentrated, thereby preventing damage due to shock or sudden load during use, And a cavity for holding a space for a mold.

Generally, when a concrete wall having a predetermined thickness is to be installed, it is installed at a distance such that a wall made of a wood plate or a metal plate is opposed to the wall by a thickness of a wall to be installed, When concrete is cured by curing, the concrete wall is constructed.

Conventionally, as described in the Utility Model No. 20-2015-4657 filed by the present applicant, a hole is formed in a fixed portion forged at one side of a shaft portion, and a forging portion is formed around the hole However, in the case where a sudden load is applied or a load is continuously applied, the peripheral portion of the hole is ruptured and a safety accident occurs The problems such as these were still intrinsic.

Also, in the conventional mold cavity maintaining tool, the fixing corners are formed in angular or chamfered shapes, so that there is a problem that a worker hurts a hand during handling and a work clothes is damaged.

The present invention has been made in order to solve the above problems of the prior art, and it is an object of the present invention to provide an apparatus and a method for preventing a safety accident from occurring by forming a plurality of reinforcing protrusions around a hole portion of a fixing portion, And a spacer for retaining the mold.

Another object of the present invention is to provide a gap holding member for a mold which can prevent the worker from being hurt or the work clothes from being damaged during the work by forming the corner of the fixing part at the round part.

In order to achieve the above-mentioned object, the mold space maintaining tool according to the present invention has a threaded portion to be coupled to a cone nut at one side thereof, a die having a fixing hole formed at the other side thereof with a fixing hole fixed to the die, The forging space retaining portion is characterized in that a forged reinforcing portion is formed in the periphery of the fixing hole formed in the fixing portion and a plurality of reinforcing ribs are protruded from the surface of the forged reinforcing portion.

In addition, in the mold space holding tool according to the present invention, the rounded portion is formed at the tip corner of the fixing portion.

According to the present invention, a plurality of reinforcing bands are protruded from the fixing hole of the fixing portion to prevent the rupture and cutting of the peripheral portion of the fixing hole due to the load at the time of construction of the wall surface. As a result, And the corners of the fixing part are formed in a round shape, so that it is possible to prevent the worker from being hurt and the work clothes being damaged during the work.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an overall front view showing a mold cavity holding tool according to the present invention,
Fig. 2 is a partially enlarged perspective view of the mold cavity holding tool according to the present invention,
Fig. 3 is an enlarged cross-sectional view along the line AA of the mold cavity holding tool according to the present invention,
Fig. 4 is a view showing the use state of the mold space holding tool according to the present invention. Fig.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

In the drawing, the gap holding tool 10 has a circular cross section and a tip end of the shaft portion 20 is formed with a threaded portion 21 to be fastened to a cone nut, and a fixing portion 30 is formed on the other side.

The fixing portion 30 is formed flat by a forging operation, and a fixing hole 31 is formed at one side thereof.

A plurality of reinforcing ribs 33 are formed on the surface of the forged reinforcing portion 32 so as to be spaced apart from each other by a predetermined distance in the outer peripheral portion of the fixing hole 31, As shown in Fig.

A plurality of the reinforcing ribs 33 protrude from the front ends of the fixing holes 31 at predetermined intervals to prevent the fixing holes 31 from being torn or cut due to the load after the installation.

The reinforcing band 33 may be formed in a plurality of, for example, three, two or more, and the cross section may be formed in a triangular shape, a semicircular shape, or the like. A square, or the like.

On both sides of the fixing portion 30 and at positions corresponding to the fixing holes 31, an external reinforcing portion 34 protruding outwardly in the forging operation is formed.

In the vicinity of the position where the fixing portion 30 and the shaft portion 20 are connected to each other, a cutting notch 35 for forming a wall surface and cutting when the form is removed is formed opposite to each other.

A rounded portion 36 is formed at the leading edge of the fixing portion 30 so as not to be injured during operation or to damage work clothes.

The mold spacing member according to the present invention is used when constructing a concrete wall or the like.

4, after the molds 40 and 41 are installed at a distance corresponding to the thickness to be applied, the gap holding tool 10 and the cone nut 50 An unillustrated fixing pin is inserted and fixed into the mold 40 at one side of the gap maintaining hole 10, that is, at the fixing hole 31 formed at the fixing portion 30, A predetermined distance is maintained when the screw is fastened to the screw portion 21 through the cone nut 50 from the outside.

When curing is performed after a certain period of time after the concrete is put between the dies 40 and 41, the dies 40 are separated while impacting the fixing part 30 protruding from the wall, The concrete wall 41 is cut off, and then the mold 41 and the connut 50 are separated from each other. Thus, the construction of the concrete wall surface is completed.

After the concrete is injected into each of the dies 40 and 41, a load is applied to the fixing hole 31 of the fixing part 30 formed at one side of the gap holding tool 10 and the cone nut 50, Particularly, since a plurality of reinforcing bands 33 are protruded and formed on the surface of the peripheral forged reinforcing portion 32 of the fixing hole 31, the corresponding rigidity is improved even when a load is applied, The fixing hole 31 is prevented from being ruptured or damaged.

In addition, a rounded portion 36 is formed at the leading edge of the fixing portion 30 to prevent the worker from being injured and the work clothes being damaged at the time of work.
