Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a formwork panel that surrounds a space where concrete is poured in the construction of concrete walls, foundations, etc. of buildings.

[Prior art]

Conventionally, as shown in FIG. 10, this type of form panel has been constructed by assembling vertical frame members 1a, 1a and horizontal frame members 1b, 1b made of wood into a rectangular frame body 11 by nailing or the like. Both vertical frame members 1a of body 1,
A crosspiece 2 was separately attached between the frames 1a, and a planar material 3 made of plywood or the like was similarly stretched from one side of the frame 1 by nailing or the like.

However, with formwork panels configured like this,
When piecing them together vertically or side by side horizontally, it is necessary to ensure that the frame 1 has a sufficient thickness so that the panels can come into contact with each other stably, which makes the panels bulky and makes it difficult to store and transport them. It has the disadvantage of causing inconvenience. In addition, in order to temporarily fix each formwork panel in a predetermined position, it is necessary to add another crosspiece, etc., which requires a large space for construction, for example, when constructing a foundation. However, it also has the disadvantage that the excavation width must be made extra wide, making construction time-consuming. Furthermore, since the material is wood, it is not only easy to get damaged after repeated use and has poor durability, but also requires manual labor such as nailing to assemble, making it time-consuming to manufacture. Furthermore, as mentioned above, when adding panels in the horizontal direction, it is done by butting the end faces of each other, so in order to adjust the overall length to the planned dimension, for example, a part of the panel placed on the end side may be cut off. This tends to require processing, making the construction even more complicated, and once the panels are cut, they cannot be reused as a general-purpose product, making them extremely uneconomical.

[Purpose of invention]

The present invention eliminates the above-mentioned drawbacks of the conventional example, does not take up much space when stored or transported, and does not require much extra space when temporarily fixed at a construction site due to the addition of crosspieces, etc. To provide a formwork panel which is excellent in durability and whose horizontal arrangement dimensions can be easily varied and adjusted.

[Structure of the invention] In the present invention, the formwork panel is made of a rigid flat material such as a steel plate, has a rectangular outer shape, has a horizontal flange formed on the upper edge, and has the horizontal flange formed on one side edge over a predetermined area including the lower edge. A vertical flange is formed that extends on the same side as the flange, and the vertical flange is moved laterally by the thickness of the flange than the end face of the flange-free area from the upper end of the one side edge to the upper end of the vertical flange. It is characterized in that two or more distance member insertion holes are formed so as to protrude, and at least one of them is located at a height corresponding to the lower end of the flange-free area.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 9.

The formwork panel 5 is made of a steel plate, and has a horizontally long rectangular outer shape as shown in FIG. It is formed. A predetermined small section from one end of the upper edge is cut out from the horizontal flange 6 to form a notch 6a. on the other hand,
On the side edge near the notch 6a, a vertical flange 7 having the same width as the horizontal flange 6 from the lower end to a little before the upper end is bent at a right angle to the main surface 5a to form the horizontal flange 6. They are formed to protrude in the same direction. As shown in an enlarged view in FIG. 2, this vertical flange 7 is positioned laterally by a flange thickness d from the end surface 5b of the flange-free area extending from the upper end of the side edge to the upper end of the vertical flange 7. It's made to stick out.

The vertical flange 7 has a notch 7a for fitting a crosspiece at a portion corresponding to approximately the middle position of the side edge of the main surface portion 5a.

On the other hand, two distance member insertion holes are formed in the upper part of the main surface part 5a so that the upper part of the opening edge is aligned with the upper end of the vertical flange 7, in other words, on the horizontal line at a height corresponding to the lower end of the flange-free area. 8, 8 are formed divided into left and right.

The above is an explanation of the formwork panel 5 on one side surrounding the concrete pouring space, but in the case of the other single side panel 5' placed opposite to this as shown in Fig. 3, it has a symmetrical shape. formwork panels are used. That is, the side edges where the vertical flange 7' is formed are left and right opposite to those in the above case, and the notch 6'a formed by cutting out a part of the horizontal flange 6' is also left and right opposite to the above case. They are formed in such a way that each part faces each other, and the individual shapes are the same. Regarding the distance member insertion holes 8', 8', if the pitch to the side edge near these is different on the left and right, the pitch on the opposite panel will be reversed left and right, but they will always be set at opposite positions, In the above embodiment, the left and right pitches are the same, and there is no difference between the left and right panels.

The assembly procedure for adding and arranging a plurality of formwork panels 5, 5' is performed as follows.

(1) A pair of formwork panels 5, 5' having vertical flanges 7, 7' with opposite left and right side edges, each with their flanges facing outward and each horizontal flange 6, 6' facing upward. They are arranged facing each other at a predetermined interval, as shown in FIG. As a result, the vertical flanges 7, 7' of the mutual panels 5, 5' are aligned on one edge side facing each other, and the respective distance member insertion holes 8, 8'
are also aligned so that they face each other.

(2) Distance members 9, 9 are attached between the opposing panels 5, 5' through opposing distance member insertion holes 8, 8'. As shown in FIG. 4, this distance member 9 includes a separator 10 having screw holes 10a and 10a at both ends and formed to the length of the distance between the facing panels 5 and 5', and a separator 10 formed to have the length of the spacing between the facing panels 5 and 5', and the distance between the panels 5 and 5'. Stance member insertion hole 8,
8' and has a male threaded portion 11a that can be screwed into the screw hole 10a of the separator 10. In addition, as shown in FIG.
12a and receiving seats 12b, 12b, and the length between both receiving seats 12b, 12b is the opposing panel 5,
Separator 12 set according to the interval between 5'
and a nut 1 that can be screwed into the male threaded portion 12a.
A distance member 14 consisting of a combination of 3 and 13 may also be used. Holes 11b and 13a for mounting wedges are formed in the bolt 11 and nut 13, as shown in FIGS. 4 and 5.

(3) Match the vertical flanges 7, 7' of the next panel 5, 5' against the side edge of the previously placed panel 5, 5' on which the vertical flanges 7, 7' are not formed. As a result, the next panels 5, 5' are added and arranged in the horizontal direction, and similarly to the previous case, distance members 9, 9 are attached to regulate the spacing between the opposing panels 5, 5' to a predetermined distance. As a result, a gap G corresponding to the flange thickness d is formed at the abutting portion of the first panel and the next panel, as shown in FIG. 6, in a portion corresponding to the flange-free area on the side edge of the next panel.

(4) Similarly, the next panel 5,
5′ are arranged in the horizontal direction, and at the end of this arrangement,
As shown in FIG. 3, a panel 5' is added to the array side of the panel 5, and a panel 5 is added to the array side of the panel 5'. Regarding the arrangement side of the panels 5, the side part of the end panel 5' is attached to the side of the leading panel 5 so that the lateral flange 6' of the end panel 5' overlaps the lateral flange 6 of the leading panel 5. Lay it on the inward facing side of the section.
The same applies to the arrangement side of the panels 5', and a distance member 9 is attached between the opposing end panels 5, 5' in the same manner as in the above case.
By sliding the end panels 5', 5 in the arrangement direction relative to the leading panels 5, 5', the overall horizontal arrangement length can be arbitrarily adjusted.

With the above arrangement, the vertical flanges 7 and 7' are located at the start and end ends of the horizontal arrangement of a large number of parallel panels, respectively, and the vertical flanges 7 and 7' are positioned against the other formwork surface materials surrounding both ends of the concrete pouring space. , the vertical flanges 7, 7' are butted against each other. The end panel may be joined such that its lateral flanges are below the lateral flanges of the leading panel and the inward facing surface of the end panel overlaps the outward facing surface of the leading panel.

(5) Panels 5 and 5' arranged as above
When adding another panel 5, 5' on top in the vertical direction, on the composite side of panel 5', the outer side of the upper panel 5' is attached to the inward surface of the lower panel 5', as shown in FIG. The lower sides of the orientation surfaces are overlapped, and the vertical flange 7' of the upper panel 5' is locked to the upper end of the vertical flange 7' of the lower panel 5', while
Connect the lower edge of the upper panel 5' to the lower panel 5,
It is placed on separators 11, 11 interposed between 5'. As mentioned earlier, the lower panel 5',
5', a gap G corresponding to the flange thickness d is ensured, so the vertical flange 7' of the upper panel 5' which is not at the end position is connected to the lower panel 5'.
There is no problem in locking the upper end of the vertical flange 7'. Also in the case of the upper panel, panel 5'
The side arrangement uses panel 5 as the end panel, and conversely, the panel 5 side arrangement uses panel 5' as the end panel. After that, in the same way,
Add the top panel to the desired height. The distance member 9 keeps the separator 10 and bolts 11 loosely screwed together until the upper panel is mounted, and connects the overlapping portion of the upper side of the lower panel and the lower side of the upper panel to the separator 10 and bolts 11.
The upper and lower panels are integrated by tightening them.

(6) Panel 5 combined in this way,
On the outward facing side of 5', there is a notch 5 formed in the vertical flanges 7, 7' of each panel 5, 5'.
Using the panels 5 and 5'b, the crosspieces 15 are laid horizontally as shown by the imaginary lines in FIG. 3, and the panels 5 and 5' are reinforced. This crosspiece 15 is pressed against the outward facing surface of the panels 5, 5' by means of wedges fitted into the holes 11b of the bolts 11 mentioned above. If necessary, the transverse flanges 6, of the panels 5, 5'
A notch 6a formed by cutting out a part of 6',
6'a may be used to attach a crosspiece in the vertical direction. As shown in the cross-sectional view in Figure 8, the upper and lower panels are successively joined so that the upper panel overlaps the inner side of the lower panel, so when pouring fresh concrete into the space surrounded by these panels, the upper and lower panels overlap. There will be no inconvenience such as concrete seeping into the wall and impairing the flatness of the concrete wall surface.

(7) After pouring fresh concrete, de-framing is carried out after a predetermined curing period, starting from the upper panel. In this case, bolt 1 of distance member 9
1 is located on the outward facing side of the panels 5, 5', so if the bolt 11 is unscrewed from the separator 10 remaining in the concrete, it can be easily removed by simply pulling the panel upward.

When storing or transporting, stack each panel 5 so that the outward and inward surfaces of the corresponding flanges 6 and 7 overlap, as shown in FIG.
Alternatively, by arranging them, the storage efficiency and transportation efficiency can be improved since they are not bulky.

[Effect of idea]

Since the formwork panel of the present invention has the above configuration, the following effects can be obtained.

(a) Panels can be stacked or arranged closely without creating unnecessary gaps between them, making them less bulky.
The efficiency of storage and transportation work is greatly improved.

(b) The length of the horizontal array can be freely adjusted by sliding the panel at the end.
Cutting panels to adjust dimensions as in conventional methods eliminates the need for laborious work, improves workability, and avoids uneconomical situations such as cut panels becoming useless as general-purpose products. can.

(c) It can be constructed not only from wood but also from rigid planar materials such as steel plates and reinforced plastics, and by using these materials, it can be made highly durable without damage even after multiple uses. I can do it. In addition, by employing the above-mentioned materials and performing press or other machining or molding, it is possible to automate manufacturing, and there is no need to rely on manual manufacturing such as nailing as in the conventional example.

(d) Since a flange is formed on one side of the upper edge, sufficient strength is ensured to maintain flatness.
In particular, by forming a notch in a part of the flange as in the example, it is possible to use this notch to attach a crosspiece to the outward facing side of the panel, which requires extra space. Not at all.
