Abstract

PURPOSE:To make assembly disassembly easy and to correspond with preparing a product of a proper dimension, by constituting main bodies having projected parts on each one end, inserting channels on their other ends and a plurarity of graved sliding channels, a stopping plate set on the projected parts, a sliding plate sliding along the sliding channels and a disphragm inserted in the inserting channels. CONSTITUTION:Projected parts 8 and 8' are set on one ends 7 and 7' of main bodies 1 and 1', and projected parts 11 and 11' are set on the other ends 10 and 10'. U-shaped inserting channels 13 and 13' into which a diaphragm 12 supporting the forward and backward movement of a sliding plate 3 is inserted is set on the inner wall faces of the projected parts 11 and 11'. Moreover, on the inner faces 15 of the side walls of the main bodies 1 and 1', a plurarity of sliding channels 16 are graved at mutually facing positions in the longer direction. The main bodies 1 and 1' are jointed together in their inserting cut channels 6 and 6' of the bottom parts 5 and then, a stopping plate 2 is fixed on the projected parts 8 and 8' of the end parts 7 and 7' with screws through screw holes 9 set on the projected parts 8 and 8'. Then, a sliding plate 3 is inserted in such a way that it can be slided in the sliding channel 16. Then, the diaphragm 12 where screw rods 20 and 20' on whose apexes a transferring plate 3 is fixed are perforated is inserted. A concrete form is thereby assembled.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prefabricated thermosetting synthetic resin concrete formwork.

Conventionally, such formwork has often been made of metal such as iron. However, metal formwork
It was rusty, took time to transport and assemble, and was complicated to handle, and different formwork had to be prepared for each different length and shape of the concrete product.

The present invention eliminates these drawbacks and provides a concrete formwork that can be easily, simply, and quickly assembled in a workshop from parts previously made in a factory or the like.

Originally, formwork is required to meet the requirements of strength, precision, speed, and economy, and the present invention can satisfy all of these conditions.

That is, as mentioned above, the formwork of the present invention uses a thermosetting synthetic resin that has sufficient strength to compete with conventionally used iron formwork, thereby making it easier to pour concrete. It is extremely easy to dismantle, as it does not deform due to its ability to withstand the fixed load, working load, and lateral pressure of concrete during construction.

Furthermore, the formwork is a so-called casting mold for creating the shape of poured concrete, and it is necessary that the finished concrete has the dimensions as shown in the drawing.

Vertical, horizontal, cross-sectional dimensions of each part, opening dimensions, etc. must be constructed accurately as shown in the drawings, and the present invention can accurately mold these conditions.

Furthermore, formwork work plays an important role not only in frame work but also in the overall construction process.

It is common for members to be repurposed repeatedly, so much so that formwork construction and formwork work are often referred to as transportation work.However, in the present invention, as mentioned above, formwork parts are made in advance at a factory. Because it is assembled on-site, unnecessary formwork transportation work is omitted, speeding up the construction process.

Furthermore, the present invention is made of thermosetting synthetic resin, which is lightweight and has excellent removability, instead of expensive and heavy iron formwork, so it is not only strong but also easy to transport, inexpensive, and requires skilled labor. It has the advantages of not requiring any additional processing, high versatility, and being economical.

Next, the present invention will be explained with reference to the drawings. As shown in FIG. ′, consists of a hole pipe 4 and a weir plate, and consists of a pair of main bodies l, 1
' is a nine-fitting notch $6.6' set at the longitudinal end of the bottom part 5.
A gutter-like body with an upper opening is formed by fitting with the upper part.

One end 7.7' of each main body 1.1' is provided with protrusions 8, 8' that protrude outward. screw holes 9.9'...
... has been drilled.

On the other hand, the other end portion 10.10' is provided with a protrusion 11.11' that protrudes outward like the protrusion 8.8', which will be described later. Slide plate 3
A U-shaped fitting groove 13, 13' into which the weir plate 12 for supporting the forward and backward movement of the tank is fitted is bored in the inner wall surface and communicates with the end lateral grooves 14, 14' of the bottom part 5.

The protrusion 9.9' is one protrusion! It is formed so as to fit snugly into a U-shaped fitting groove 13.13' provided at 1.11', and is a trap so that it can be continuously extended.

Furthermore, longitudinal sliding grooves 16.16' are provided at opposing positions on the inner surface 15.15' of the side wall of the main body 1.1'.
・Multiple rows are drilled in parallel. Also, the main body 1. l/
A plurality of reinforcing columns 18, 18' are provided at predetermined intervals on the outer surface 17, 17' of the side wall.

The bodies 1 and 1' thus formed are fitted into the fitting cut grooves 6 and 6' of the bottom part 5, and then the protrusions 8 and 8' of the end parts 7 and 7' are bored. The stop plate 2 is fixed with screws through the screw holes 9 and 9'.

Next, on the side of one of the protrusions 11.11', a sliding protrusion 1 is attached to the side edge of the protruding part 11.11' so as to slide within the sliding groove 16.16'.
Slide plate 3 with groove 16.16'
Align the protrusions 19 and 19' and fit snugly into the other end 10 and 10'.

Next, the slide plate 3 is pressed into contact with the slide plate 3 in the U-shaped fitting groove 13.13' provided in the protrusion 11.11' and the end lateral groove 14.14' of the bottom part 5. There is a feeding plate 3 at the rounded tip that operates the front and back sliding and supports it.
The weir plate 12 that passes through the threaded rod 20, which is fixed to the
Formwork A is assembled by fitting.

In addition, a hole pipe 4 is inserted through the stop plate 2 and slide plate 3 through both plates 2 and 3 due to the concrete product being molded.
Different cross-sectional shapes of the hole tube 4 are used depending on the desired product.

Furthermore, in the present invention, the expansion and contraction adjustment is not limited to the length direction, but by fitting auxiliary members into the fitting cut grooves 6, 6' of the bottom part 5, it is possible to freely adapt to changes in width and direction. It is possible to commercialize it.

Furthermore, in the present invention, the above-mentioned formwork A can be used not only in a horizontal position, but also in a vertical form, in which case, depending on the weight of the poured concrete, This does not require a slide plate or the like.

As described above, the present invention includes the main body l, 1', the stop plate 2,
Mortar is injected into the formwork A constructed by assembling each member of the slide plate 3, hole pipe 4, and weir plate 12, and after hardening and molding,
Each member is removed and demolded.

As described above, the present invention is easy to assemble and disassemble, and can be manufactured into any suitable size by rotating the screw rod 20, and by connecting and extending the product, it can be manufactured to any length or in a single row. It has the advantage of being able to produce a large number of products, something that could never be achieved with conventional molds, and has many practical effects.
