Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a formwork apparatus for producing concrete plates.

(Prior art) The plate thickness of general secondary concrete products (manufactured at prefabricated, curtain wall factories, construction sites, etc.) is constant for each type (wall plate, floor plate, etc.). Flat roof panels are often manufactured with a slope.

In producing the above-mentioned secondary concrete products, in order to produce different types of products,
Conventional formwork is not compatible, and each product has its own formwork.

However, in recent years, with the diversification of designs, the types of shapes and thicknesses of concrete plates have increased significantly. If dedicated formwork was manufactured for each of these many types, the manufacturing cost of the formwork would increase, problems with management and storage space would occur, and as a result, the price of concrete plates would increase. This makes it difficult to respond to market demands.

(Problems to be Solved by the Invention) As mentioned above, with the diversification of concrete prefabricated buildings today, there is a demand for concrete plates with various shapes, thicknesses, and slopes. Depending on the situation, independent formwork is manufactured each time or partially modified and used.

Therefore, this invention has an extremely simple structure,
The object of the present invention is to provide a versatile formwork device for manufacturing concrete plates that can be manufactured by freely adjusting the thickness, slope, etc. of concrete plates.

[Structure of the Invention] (Means for Solving the Problems) The present invention is characterized in that a second side frame is further assembled to overlap the side surface of a first formwork arranged as a frame for manufacturing a concrete plate. A round hole is formed in one side, and a long vertical hole is formed in the other side, and a rod-shaped jig having approximately the same diameter is passed through the round hole from the horizontal direction and penetrated into the vertical hole. The frame is integrated and the height and inclination of the frame can be adjusted by vertically shifting the positional relationship between the first and second frames.

(Function) With the above method, the thickness and slope of the concrete plate can be freely set by adjusting the height and inclination of the formwork, so the same formwork can be used to manufacture various types of concrete plates. .

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows the basic configuration of this invention. When a concrete plate is created, as shown in the figure, a first formwork 2 having an approximately L-shaped cross section is placed on a metal base 10.
0 is placed. A vertical hole 2a is formed in the side wall of this first formwork 20. Next, the inside of the first formwork 20 (the side where concrete 50 is poured)
The second formwork 30 is arranged so as to overlap. The second formwork 30 also has a substantially L-shaped cross section, and is combined with the first formwork 20 in an upside-down L-shape when viewed from the cross section. Also, on the side wall of this second formwork 30,
A round hole 3a is formed at a position corresponding to the vertical hole 2a.

Next, the first and second formworks 20 and 30 can be shifted vertically by height adjusting means.
That is, the bolt 41 is inserted from the round hole 3a side and penetrated to the vertical hole 2a side. Then, the nut 42 is screwed together. As a result, the first and second formworks 20 and 3
It is integrated with 0. In this case, the second formwork 30
, a protruding piece 31 toward the first formwork 20 is shown.
is formed. The piece 31 is for preventing concrete from entering between the formwork or into the hole when concrete is poured.

Further, since there is a gap between the main bodies (side walls) of the first and second formworks 20 and 30 due to the presence of the piece 31, a spacer 43 is arranged to maintain the gap between the main bodies parallel and stably. is planned. Furthermore, since the nut 42 is located on the vertical hole 2a side,
In order to stabilize the presser, it is tightened through a seat 44. Figure B shows the bolt 41, nut 42, spacer 43, and seat 44.

According to the concrete plate manufacturing apparatus described above, the height of the second formwork 30 can be freely adjusted by loosening the bolts 42 before concrete pouring. Therefore, it is possible to produce concrete plates of a desired thickness using the same formwork apparatus.

As shown in FIG. 2, this device further includes the height adjusting means provided at a plurality of locations in the longitudinal direction of the formwork.

As a result, by selecting the degree of adjustment of the height adjustment means at each location, the concrete plate can be manufactured with a slope on its plane, and this slope can also be freely selected.

Figure 3A shows a concrete plate 60 with a slope.
shows a cross section. In other words, this concrete plate 60 has a thickness H0 at one end and a thickness H1 at the other end.

When manufacturing such a concrete plate 60, formworks 61 to 64 are assembled on the upper surface of the metal base 10, as shown in FIG. Then, before pouring concrete, the heights of the formworks 63 and 64 are adjusted as shown in C in the same figure, and the heights of the formworks 61 and 62 are adjusted by tilting them. be exposed.

This makes it possible to easily manufacture a concrete plate 60 having an inclined plane as shown in FIG.

The formwork apparatus of the present invention is not limited to the above embodiments.

FIG. 4 shows a formwork apparatus according to another embodiment of the invention.

The first formwork 70 attached to the metal base is
It basically has a lower wing section 7c and a side wall (vertical wing section) 7b, and the upper tip of the side wall 7b is bent inward.

Then, this first formwork 70 has a bent portion 7
A plurality of fixed plate parts 81 and 82 are vertically attached between the wing part a and the wing part 7c in the longitudinal direction. The aforementioned round holes 8 are provided in the fixing plate portions 81 and 82, respectively.
a, 8b are formed.

On the other hand, the second formwork 90 has a substantially U-shaped cross section, as shown in FIG. Further, vertical holes 9a and 9b are formed at positions corresponding to the round holes 8a and 8b. The first and second formworks 70 and 90 are constructed using bolts 1 as shown in FIG.
00 and seat 101 and are tightened and integrated. FIGS. 4D and 4E show an example in which the heights of the integrated formworks 70 and 90 are adjusted to the lowest state and the highest state.

In the case of the above embodiment, since the heads of the bolts do not protrude from the surface on which the concrete plate is formed, the side surface of the concrete plate can be finished smoothly.

FIG. 5 shows a formwork 11 of the type explained in FIG.
This is an example of a case where a concrete plate 130 is manufactured using a formwork 120 of the type described in FIG. Steps 131 and 132 are formed on the side surface of the concrete plate 130. These steps 131 and 132 are effective when joining panels together as shown in FIG. 2B.

In other words, due to the difference in level, the sides of the adjacent concrete plates 13A and 13B can be interlocked, and by filling the space with the waterproofing agent 13C, a good waterproof effect and a bond between the concrete plates can be obtained. .

In the above explanation, the first formwork is fixed, and when adjusting the height, the second formwork is moved up and down. However, conversely, the second formwork is in a fixed position. Alternatively, the first formwork may be used by moving it up and down.

FIG. 6 is a diagram further showing an example of the use of the apparatus of the present invention. For example, when the roof plate is formed from a single concrete plate, it is necessary to form a slope on the upper surface of the roof plate body 150 to improve drainage, as shown in FIG. 1A. A parapet 151 is provided at the edge of the main body 150, and the parapet 1
51 and the upper surface of the main body 150, it is necessary to form a groove 152. It is also necessary to make the grooves 152 sloped to improve drainage.

The apparatus of the present invention is also extremely useful when manufacturing roof panels having such a shape. As shown in FIG. 5B, in order to create a roof board consisting of a parapet 151 and a main body 150 with varying thickness and an inclined groove 152 all at once, as shown in FIG. 5C, as shown in FIG. A type of formwork 120 is employed.

That is, the formwork 1 is placed inside the outer frame 160 as an inner frame.
20, and a parapet 151, a groove 152, etc. are formed between the outer frame and the inner frame. In this case, by keeping the first formwork 90 fixed and using the second formwork 70 as a moving side, the thickness of the concrete plate can be gradually changed and the grooves can also be sloped.

[Effects of the Invention] As explained above, the present invention provides a versatile formwork device for producing concrete plates that can be manufactured by freely adjusting the thickness, slope, etc. of concrete plates with an extremely simple structure. can be provided.
