Description

[Detailed description of the device] [Industrial application field] This project is for sealing construction of joints of precast concrete structures such as PC panel method, which has become very frequently used in the field of construction and civil engineering in recent years. The present invention relates to a backup material loading device related to a backup material loading operation at the time of.

[Prior Art] Conventionally, in the case of sealing work in the field of construction and civil engineering, a backup material is loaded into a joint to be sealed by holding a bamboo spatula or a metal spatula in hand and simply pushing it into the joint. It is done in.

[Problems to be Solved by the Invention] The conventional techniques described above have the following problems.

In the conventional method, a portion having a strong pushing force becomes deep and a portion having a weak pushing force becomes shallow, so that the backup material cannot be loaded at a certain depth.

In addition, when attempting to load with a constant depth as much as possible by using this method, it is necessary to confirm the depth with a ruler or the like quite often.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide the following things.

Even a non-expert can easily and surely load the backup material to a certain depth and improve the working efficiency.

[Means for Solving the Problem] In order to achieve the above object, the present invention is as follows.

That is, the one of the present application is a substrate portion 2A configured in a front square shape.
The wheel body 4 is rotatably attached to the base plate portion 2A of the handle 2 which is composed of the base plate portion 2A and the holding portion 2B which is connected to the base plate portion 2A and extends obliquely upward to the front right.
Left and right wheels 5A, 6A are rotatably mounted in the lower left corner and the lower right corner of the vehicle in the front-rear direction, and
The lower portion 4A is a backup material filler configured so as to project downward from the lower sides of the left and right wheels 5A and 6A.

In this case, the wheel body 4 can be attached to the board portion 2A so as to be adjustable up and down.

In addition, a holding part that extends diagonally upward to the front right on the base plate 2A.
The right end 2B1 of 2B can be configured in a vertical state, and the right end 2B1 can be configured as an inclined surface.

[Operation] The device of the present invention operates as follows.

In a joint 7 which is a construction work target of a construction / civil engineering structure requiring a backup material loading, a backup material 8 is fitted in an upper opening of the joint 7, and the wheel body 4 is mounted on the upper surface of the backup material. By pressing, the backup material is pushed into the joint 7.

After that, when the wheels 5A and 6A are rotated along both sides of the joint, the backup material is sequentially pushed by the rotating wheel body 4 to a predetermined depth.

It should be noted that although the illustrated ones are shown in the case where the holding portion 2B is supported in a so-called reverse-handed state, it is needless to say that the necessary work is performed by supporting the holding portion 2B in a so-called forward-handed state which is not the reverse-handed state. It can also be done.

Embodiments of the Invention Embodiments will be described with reference to the drawings.

Reference numeral 1 is a backup material filler of the present invention made of synthetic resin material, light metal material, etc., and it is a base plate portion 2A formed in a square shape on the front side and extends diagonally upward to the front right side connected to the base plate portion 2A. The wheel body 4 is rotatably attached to the base plate portion 2A of the handle 2 including the holding portion 2B.
Left and right wheels 5A and 6A are rotatably attached in the front-rear direction to the lower left corner and the lower right corner of the base plate portion 2A, and the lower portion 4A of the wheel body 4 is a lower side of the left and right wheels 5A and 6A. It is configured to project further downward.

In the figure, 3 is an axle, and 5 and 6 are left and right axles.

Reference numeral 2C denotes a vertically elongated hole formed in the center of the base plate portion 2A. An axle 3 is attached to the elongated hole so that the axle 3 can be adjusted to move up and down in the left-right direction, and the wheel body 4 can be rotatably attached to the axle 3. .

Therefore, as for the lifting structure of the axle 3, referring to FIGS. 3 and 4, it is necessary to adjust the lifting by making the structure in which the bolt head 3A is provided on one side and the nut 3B is screwed on the other side. In this case, the nut 3B is tightened and loosened.

In addition, a holding part that extends diagonally upward to the front right on the base plate 2A.
The right end 2B1 of 2B can be configured in a vertical state, and the right end 2B1 can be configured as an inclined surface.

The lower portion 4A of the wheel body 4 is provided with the left and right wheels 5A, 6
It is configured to project downward from the lower side of A.

The projecting size of the lower portion 4A is determined by adjusting the vertical movement of the axle 3.

[Advantages of the Invention] Since the present invention is configured as described above, it has the following effects.

In the case of the present application, after adjusting the depth of entry of the wheel body 4 into the joint 7, the backup material 8 is loaded at a constant depth by simply rolling the wheel body 4 in the joint 7. Therefore, even an unskilled person can perform the work quickly and surely in a labor-saving state.

In this case, in the case where the wheel body 4 is configured to be able to move up and down, the embedding depth of the backup material 8 with respect to the depth of the joint 7 can be matched to the actual condition of the construction site.

Further, as shown in FIG. 7, when there is a wall 9 orthogonal to the longitudinal direction of the joint 7 with respect to the joint 7, it is not possible to push in the end vicinity portion 8A of the backup material 8 only by the wheel body 4. .

In such a case, as shown in FIG. 7, the right end portion 2B of the holding portion 2B.
It is convenient to use the one in which the right end portion 2B1 is configured to be an inclined surface while the 1 is configured in a vertical state.

That is, referring to FIGS. 7 and 8, a portion near the end of the backup material 8 located in the upper opening of the joint 7.
The right end portion 2B1 of the holding portion 2B is brought into contact with the upper surface of 8A from above and pushed downward as it is.
Can be easily and surely fitted.

As described above, the present invention, like the joint part of the precast concrete structure such as the PC panel method which has been actively used in recent years particularly in the field of construction and civil engineering,
It is very effective when the loader of the present invention is used for joints formed on the same surface.
