Description

[0001] The present invention relates to a safety stopper for opening and closing a mold,

The present invention relates to an efficient safety stopper that can be easily and easily moved after a mold is half opened and closed and can be fixed even with a small force when using a concrete formwork.

In general, in order to form a wall of a building or a mortar wall, a form supporting the shape must be inevitably installed until they are solidified.

In addition, when these molds are composed of a plurality of molds, and these molds are connected to each other so as to be hermetically sealed, and when the molded products are taken out to the outside, or when the internal parts are cleaned or repaired and the connection parts of the molds are repaired, The assembled mold must be opened or opened to the outside.

In the case of these formwork walls, most of the steel molds are heavy, so the weight is heavy, and in such a case, there is a risk of injuring the operator in opening the wall or opening the wall at a predetermined angle.

Conventionally, the wall and the wall are connected with each other by a chain so as to be fixed in a state that the wall is opened. However, the larger the opening angle of the steel mold and the backward angle of the heavy weight are, the more difficult it is to support such a wall , There was a problem that the risk was high.

In addition, a separate steel member other than the chain is laid diagonally toward the wall to support the wall. However, it is also difficult to fix the position of the steel member, and there is a problem that the steel member must be newly installed every time the steel member is installed. There was a problem that this was uncomfortable.

Therefore, It is to be understood that equivalents and modifications are possible.

According to one embodiment of the present invention,

Hereinafter, a mold half opening / closing safety stopper according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4. FIG.

The mold half opening / closing safety stopper according to the present invention includes a support portion 10, a lower plate 20, a side plate 30, and a safety stopper portion 40.

The support portion 10 is for supporting a bottom plate 20 to be described later, and the support portion 10 is horizontally installed on the ground on which the mold is installed.

The lower plate 20 is mounted on the upper surface of the support portion 10 and has a predetermined thickness. For convenience of explanation, the lower plate 20 will be described as a rectangular plate, The side plate 30 to be described later for forming a mold is also used in total, so that a square frame can be formed.

A plurality of hinge means 22 are spaced apart from each other and formed to protrude along a side edge 21 having a predetermined thickness (in the case of a square frame, each formed on a quadrangular surface) for hinge engagement of the side plate 30 .

The side plate 30 is installed upright on the outer frame 21 of the lower plate 20 to form a space for allowing the concrete or the like to be poured into the upper portion of the lower plate 20 And a plurality of side plates 30 are erected upright and closed to form a predetermined space. When the molded product is taken out, each of the side plates 30 is laid out to the outside and is inclined to open.

A plurality of side plates 30 are coupled to the hinge means 22 protruding from the rim 21 of the bottom plate 20 so as to correspond to the respective side plates 30, 20 can be erected upright at the corresponding rim 21 of the rim 20, or can be laid out and opened.

That is, in the case where the bottom plate 20 is in the form of a rectangular plate, a total of four side plates 30 are used, corresponding to each of the rims 21 of the bottom plate 20 and hinged thereto, So that the bottom surface is positioned on the same horizontal line as the upper surface at the side surface of the lower plate 20 when erected.

Of course, with this structure, it is needless to say that the plurality of side plates 30 have a structure which can be individually opened and closed.

The safety stopper portion 40 is provided on the side edge 21 of the lower plate 20 on which the hinge means 22 is installed and when the lower plate 20 is a rectangular plate, One or a plurality or a plurality of the side plates 30 are provided for each side of the rim 21 so as to be able to take charge of the four side plates 30, respectively.

In addition, in the present invention, the safety stopper portion 40 can be used in various forms depending on the form application in which the safety stopper portion 40 is used. In the present invention, It is natural that it is possible to use (apply) regardless of the field as long as it is a purpose to fix any object or plate material by tilting it at a predetermined angle.

When the safety stopper portion 40 is tilted to the outline, the lower end of the side plate 30, which is to be opened, extends over the upper surface of the safety plate 40, So that the inclination angle at which the opening target side plate 30 is laid is maintained at a predetermined angle and the opening target side plate 30 can be opened.

The safety stopper 40 for this purpose is composed of first and second main plates 41 and 42 and a rotary plate 48.

The first and second main plates 41 and 42 are formed in a plate shape and the upper surface of the first and second main plates 41 and 42 is formed with a straight portion 45 bent downward from one side to the middle portion, And has a shape of a finishing portion 47 that is chamfered with an arc from the end of the horizontal portion 46 toward the ground following the horizontal portion 46. [

The first and second main plates 41 and 42 having such a shape are spaced apart from each other by a predetermined distance and opposed to each other in the form of a ten-pointed dowel 11 so that one side of the lower end portion between the first and second main plates 41 and 42 is connected by the connecting plate 43, And the first and second main plates 41 and 42 are integrally fixed to the side edge 21 of the lower plate 20. That is, the portion of the straight line portion 45 is fixed to the side edge 21 of the lower plate 20.)

The rotary plate 48 is a quadrangular plate in the shape of a quadrangle, and its width is gradually widened toward the upper portion, and its upper surface has a linear shape inclined downward toward one side.

The rotary plate 48 having such a shape is engaged with a portion of the rotary shaft 44 that continuously passes through the interruption of the first and second main plates 41 and 42 and is rotated between the first and second main plates In order to allow rotation. When the rotary plate 48 is rotated in the clockwise direction to stand upright, the rotary plate 48 is partially protruded to the upper portion between the first and second main plates 41 and 42 so that the lower end of the rotary plate 48 The first and second main plates 41 and 42 are brought into contact with the upper surface of the connecting plate 43 connecting the first and second main plates 41 and 42. When the first and second main plates 41 and 42 are rotated counterclockwise, A part of the rotary plate 48 is protruded to the lower part rather than the upper part of the rotary plate 48. One side of the rotary plate 48 is in contact with one side of the connection plate 43 and is interrupted so as not to rotate any more.

The operation of the rotating plate 48 can be operated in the first case and the second case according to the degree of opening of the side plate 30 which is opened and opened to the outside, And the second case is a case where the rotating plate 48 is located at the lower end without protruding upward between the first and second main plates 41 and 42. In this case,

The first case is a case where the side plate 30 is laid down by the first preset angle (the side plate 30 is partially opened), and then the position is fixed. Thus, the rotation plate 48 is rotated upward, So that the lower end of the side plate 30 lying down is locally supported on the upper plate of the rotary plate 48 so that the position is interrupted and fixed.

The second case is such that the side plate 30 is laid open at a second preset angle (the side plate 30 is fully open so that it is horizontal with the ground), which is relatively larger than the first preset angle, The lower end of the side plate 30 which is laid down is in contact with the side surface of the connecting plate 43 so as to be in contact with the side surface of the connecting plate 43. In this case, 1 and 2 main plates 41 and 42, and the positions thereof are interrupted and fixed.

In addition, the through holes 50 are formed in the first and second main plates 41 and 42 at one side of the rotating shaft 44 (counterclockwise side in the rotational axis 44) The through holes 50 of each of the main plates 41 and 42 are perforated at positions corresponding to each other so that the car shaft 51 can be inserted and fastened to the through holes 50. [

Namely, it is a matter of course that the car short shaft 51 can be attached and detached by continuously inserting the through holes 50 of the first and second main plates 41, 42 in the car short shaft 51.

Thus, in the first case, the rotation plate 48 is vertically erected so that the side plate 30 is opened at a predetermined angle to be opened, and then the position is fixed. When the rotation plate 48 is rotated counterclockwise, (51) can be controlled.

In addition, in the present invention, in the case of the side plate 30 which is rotated to the outside, the lower side of the outer side is formed with an extension 31 extending to the outside. The side plate 30 is formed so as to be horizontal with respect to the paper surface in the case of the rotary plate 48. In this case, A supporting piece 32 protruding from the bottom of one side of the side plate 30 is formed in the rotational space 49 of the rotating plate 48 spaced between the first and second main plates 41 and 42 ) May correspond to and may have a structure to be inserted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
