JPH0721730Y2 - Equipment for horizontally setting the top of waste concrete - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is to roll the crushed stones and crushed gravel in the foundation work in the construction work, and to horizontally place the top end when pouring waste concrete or the like. It is used to set the top of abandoned concrete or the like horizontally in order to place it in the.

[Conventional technology]

Conventionally, when compressing rubble stones and crushed gravel in foundation work in construction work and placing waste concrete etc., square steel pipe batanu is used by using a narrow wooden formwork etc. Concrete is generally constructed by placing it horizontally. In extreme cases, no concrete forms are used and concrete is thrown away.

Conventionally and now, this construction method is used to place waste concrete.

[Problems to be solved by the device]

Placing work such as waste concrete is carried out by the construction method described in the conventional technique, but this construction method has a problem that the top end of the waste concrete etc. is not finished on a horizontal plane and causes unevenness. There is.

In particular, according to the 1990 utility model registration application No. 2-74124,
In the construction of a continuous cloth foundation of ready-made products such as wooden buildings,
In order to install and install the foundation horizontally, it is necessary to place the top end of the waste concrete, etc. in a horizontal plane in the construction work of the waste concrete etc. as the level adjustment layer.

The present invention has been made in view of the above problems and necessity, and an object thereof is to perform a simple operation when placing waste concrete or the like, and
It is an object of the present invention to provide a device capable of reliably setting the top of a concrete such as a waste horizontally.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the following measures are taken to manufacture an instrument (only an instrument is shown in the following description) for horizontally setting the top end of waste concrete or the like in the present invention.

(A) The equipment is manufactured by using the apparatus (1) to (9) described in claim 1.

(B) The device can be made of metal or hard plastic, and the joints (1) and (2), (3) and (4), and (1) and (9) , Welding stop or adhesive stop (10).

[Action]

The equipment manufactured by taking the means for solving the above-mentioned problem is the root cutting work at the site of each construction work, and on both sides of the compaction part (11) of the stone and gravel Placing waste concrete etc. by driving (3) up to the predetermined height required for leveling by the leveling, and by driving (3) into the compaction part of crushed stone and crushed gravel and into the ground (1
2) It is possible to set the top end horizontally when doing.

By compressing at (7) and installing the device, a restraining force is applied to the extent that (3) does not fluctuate and does not fluctuate even when rotated by 90 °.

(C) Fig. 3 shows the construction procedure.

3 Fig. 1 shows a state in which (3) of the instrument is driven into the compaction part and the ground of crushed stone and crushed gravel using a wood punch or the like. In addition, when setting the top of the instrument (1) horizontally, in the present invention, one portable level (13) shown in FIG. By confirmation, it is shown that the top end of the instrument (1) can be set horizontally by only one worker.

3 Figure 2 shows the state in which waste concrete is placed up to the top of (1) where the top of the equipment is set horizontally. In addition, the top of waste concrete shall be finished horizontally by the work such as iron pressing.

3 Fig. 3 shows the concrete that has been cured to the required level, and then the equipment has been removed.
According to the 1990 utility model registration application No. 2-74124, it is shown that the foundation can be installed horizontally and set by constructing a continuous fabric foundation (14) of an existing product such as a wooden building.

(D) In FIG. 4, (3) is added to (1) shown in FIG.
And (9) shows an enlarged detailed view of the part where the device is installed. The method of installation is according to the method described in claim 1. In addition, the bolt (2) penetrates (1) and is welded or glued (1
As (0), the plate (15) for reinforcing the bolt is attached to (1) as a weld stop or an adhesive stop, so that (1)
It is intended to prevent the portion of the device (3) used as a rotating body from being damaged.

[Effect of device]

Since the present invention is constructed as described above, the effects of the present invention will be described below.

(A) The device can be reused for several times by making it from metal or hard plastic.
In addition, by attaching temporary paper tape or vinyl tape to the upper surface of (1) of the device, it can be easily removed even if cement etc. adheres when pouring waste concrete etc. On the upper surface of (1) of the equipment, there is no attachment or the like, and the top of waste concrete can always be set horizontally for reuse.

(B) Since (3) of the device is installed as a rotating body that can rotate 90 °, use (3) when using the device, and use (3) when not using the device.
Since it can be stored in the part (1), each work is carried out safely and quantitatively without being bulky for the work of transporting to and from the site of each construction work. be able to.

(C) The equipment is a portable level as shown in Fig. 3-1.
By confirming the horizontalness in the vertical direction and the horizontal direction by using the table, it is possible to set the top end of the discarded concrete or the like horizontally by a simple operation even by only one worker. This has a great effect on the problem of shortage of construction workers, which is becoming a social problem now and in the future.
