Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a batting material for reinforcing simple formwork, which is mainly applied to the construction of legal frameworks and the like.

As one of the reinforcement works for sloped ground such as slopes, facilities such as concrete slopes are installed. As formwork for constructing such concrete structures, lightweight, disposable cardboard made of waterproof and reinforced cardboard has come to be used instead of formwork boards such as metal platforms and plywood boards. Ta. Therefore, since lightweight formwork boards such as cardboard have low strength, conventionally, one or two strips of batting material were applied to the outside surface of the formboard, and they were used as vertical battens along with horizontal strips to maintain the spacing between the formwork boards. It is connected to the formwork board using a wedge.

[Problem that the invention attempts to solve]

However, when constructing the above-mentioned concrete slopes, etc., the dimensions of the slopes vary depending on the site conditions. It has to be tailored to suit the situation, and conventionally, standard-sized bata materials were brought in and cut to the required length on site before use. This not only resulted in wasted materials, but also made it difficult to work on slopes with poor footing.

The present invention improves the shortcomings of conventional simple formwork as described above, and in particular, it is possible to make the required length of the batten material that reinforces the formwork board without having to perform cumbersome work such as cutting on site. The purpose of the present invention is to provide a simple batter material for formwork that is easy to adjust and can save materials.

[Means for solving problems]

In the present invention, a tough rod 1 is formed of channel steel with a lip, locking pieces 4 are fixed to both ends of the tough rod on the release side, and side plates 3 opposite to each other at one end of the tough rod 1 are fixed. , 3 is provided with a wedge insertion hole 5, and a sliding rod 6 formed of grooved steel is inserted into the tough rod 1 so as to be able to slide in and out. It is characterized in that it is provided with a locking protrusion 10 that abuts against the locking pieces 4, 4 of the tough rod 1, and a wedge insertion hole 8 is provided in the opposing side plates 7, 7 at the other end.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In Figures 1 to 3, 1 is a tough rod, and the cross section is
It is formed of grooved steel with a lip in the form of a groove, and locking pieces 4, 4 are fixed to the inner surface between the opposing lips 2, 2 on the open side of both ends, and a locking piece 4, 4 is fixed at a suitable place near one end. Wedge insertion holes 5, 5 are provided through the opposing side plate portions 3, 3.

Reference numeral 6 denotes a sliding rod, which is made of channel steel and has a cross-sectional shape that is sized to be inscribed in the ductile rod 1, and has a length equal to or longer than the ductal rod 1. Further, wedge insertion holes 8, 8 are provided at appropriate positions near the other end of the basin rod 1 in the direction opposite to the position of the wedge insertion holes 5, penetrating through the opposing side plate parts 7, 7. A locking protrusion 10 having an L-shaped side surface is fixed between the opposing side plates 7 at a proper location near one end.

Then, as shown in FIG. 1, the sliding rod 6 is inserted into the ligament rod 1 with the release sides facing each other, and the locking protrusion 10 is inserted into both the locking pieces 4 of the ligament rod 1. It should be located between 4. Thereby, the sliding rod 6 can freely slide between the locking protrusions 10 abutting the locking pieces 4, 4.

In order to assemble the formwork using the butter material of the present invention described above, as shown in FIG. , 13 are inserted into connecting holes 14, 14 provided in the formwork plate to project outward. Then, the butter material of the present invention is applied to the outer surface of the form board 11, and the wedge insertion holes 5 and 8 are inserted into the connecting tool 1.
2, a wedge 15 is driven from above into the wedge insertion holes 5, 8 and the loops 14, 14.
1, the connector 12, and the butter material of the present invention are integrally connected.

In this case, the formwork board 11 will be of a size appropriate to the construction specifications,
Therefore, the pitch interval in the longitudinal direction of the connecting holes 13, 13 may also vary. In such a case, put the sliding rod 6 in and take it out, and remove the sliding rod 1 and the sliding rod 6.
The distance between the wedge insertion holes 5 and 8 is adjusted so that the loops 14 and 14 protruding from the formwork plate 11 are aligned with each other. Thereby, even if the formwork board 11 changes in various ways, it becomes possible to adapt it with only one type of batting material.

[Effect of idea]

As explained above, the present invention has been developed to replace the reinforcing butter material used when constructing formwork using formwork plates made of lightweight materials with low strength by using grooved steel with lips and grooved steel. It is a combination of rods and sliding rods, and the length can be adjusted and the spacing of the wedge insertion holes can be adjusted freely, so it is strong as a reinforcing batting material, and can also be used as a formwork board for construction. Even for items with different specifications and dimensions, a type of butter material can be used for both purposes.
Not only is it extremely easy to construct, but it also has many benefits, such as saving money by sharing materials, reducing transportation and storage costs, and making construction inexpensive.
