2. Description of the Related Art In the case of forming structural members such as a cloth foundation, underground beams, and walls by concrete casting, a form panel is formed by using a plywood panel or a metal panel, and between the form panels. There is generally known a construction method in which concrete is poured and the form panel is removed after the concrete is solidified. However, in recent years, a method using a form panel made of a foamable synthetic resin has been used as an alternative to this method.

According to this method, a form panel made of an expandable synthetic resin is installed and concrete is poured in the same manner as in the conventional method, but after the concrete is solidified, the structural member is removed without removing the form panel. Is used as part of For this reason, the construction can be extremely simplified, and the form panel made of the foamable synthetic resin has advantages of high heat insulation and noise reduction effects, and is less likely to corrode. Conventionally, as one of such construction methods, there is one that simplifies installation of a formwork panel on site by performing the work using a formwork panel that has been cut in advance according to the shape of a structural member to be constructed. is there.

The block-shaped foam cut in m) is sequentially cut out by a shearing device using a nichrome wire. In this case, a plurality of form panels are cut out from one foam. However, when cutting the form panels according to the shape of the structural member, many unusable portions are generated, and the yield is deteriorated. Was. That is, as shown in FIG.
When cutting out 0 or 10, many surplus portions R are generated, and the material is wasted.

(3) Further, the form panels cut according to the structural members to be constructed are relatively large, and the individual panels have a large volume, which hinders transportation, and also facilitates workability on site. Was bad.

The flat panel 12 is formed of the bent panel 1
1 is a flat panel superposed along the upper end of the first panel. The flat panel 12 has the same length and the same thickness as the bent panel 11, and is superimposed on the bent panel 11 and interconnected by the connector 13 to form a mold for forming a cloth foundation. It becomes a frame panel. At the upper end of the stand-up braided body 4, a contact piece 4a extending toward both flat panels 12, 12 is provided. By contacting the contact piece 4a with the inner wall of the flat panel 12, the interval between the flat panels 12 is kept constant. In one embodiment, the height of the flat panel 12 is about 450 mm. Here, the bent panel 11 and the flat panel 12
At the mounting position of the connector 13 in the above, cut grooves 16 are formed vertically. The connector 13 is positioned and fixed by inserting a rising piece 14b described later into the cut groove 16.

The connecting members 13 are for connecting the bent panel 11 and the flat panel 12, and a plurality of connecting members 13 are arranged at appropriate intervals between the contact surfaces of both panels. As shown in an exploded perspective view of the connecting structure in FIG. 3, the connecting member 13 connects the two substantially box-shaped panel supporting portions 14

Function to keep. In addition, the connecting portion 15 has its plate-like surface made vertical in the use state, in order to prevent the connecting tool 13 from hindering the pouring of concrete between the panels. The connecting portion is not limited to the above structure as long as it can substantially connect the respective panels in the vertical direction, and has a structure in which at least a rising piece is inserted into a cut groove of each panel. Any structure may be used as long as it is provided.

Next, a procedure for installing a fabric foundation using the formwork panel of the present invention will be described. In the construction of the cloth foundation, as shown in FIG. 1, a root cutting groove 1 is first dug, and a rubble 2 is laid at the bottom thereof to form a flat portion serving as a base of the cloth foundation. The base bar 3 and the standing bar assembly 4 are integrated by welding at a factory, and a plurality of the bars are set on the rubble 2 along the root cutting groove 1. At this time, the curved lower part of the receiving piece 3a of the base streak 3 is slightly embedded in the rubble 2 so that the lower surface thereof is completely in contact with the rubble 2 when the form panel 10 is inserted.

Next, one bent panel 11 is installed on the base bar 3 and the standing bar assembly 4. That is, the lower end of the bent panel 11 is pressed from above so as to be inserted into the receiving piece 3a of the base streak 3. At this time, the fitting piece 3b of the base streak 3 pierces the step inner wall of the bent panel 11, and the bent panel 11 is stably fixed to the base streak 3 without displacement. The bending panel 11 on the other side is also installed on the base muscle 3 and the rising muscle assembly 4 in the same manner as the above procedure.

Next, as shown in FIG.
It is installed so as to bridge over the upper surfaces of the two bent panels 11. That is, one receiving portion 14a of the panel support portion 14 is fitted to the bent panel 11 in a state where the rising pieces 14b of the two panel support portions 14 constituting each connecting member 13 are inserted into the cut grooves 16 of the bent panel 11. Put in. In this state, the upper portions of the two bent panels 11 arranged opposite to each other are connected to each other by the connecting member 13, so that they do not open outward due to the pressure from the inside received when the concrete is poured.

Further, a flat panel 12 is attached to the upper part of each bent panel 11. Each flat panel 12 is superimposed on the bent panel 11 so that the cut grooves 16 formed on the lower surface thereof coincide with the rising pieces 14b of the connecting tool 13. The lower surface side of the flat panel 12 is received by the receiving portion 14a of the connector 13 and the rising piece 14b is inserted into the cut groove 16 so that the flat panel 12 is positioned and fixed on the bent panel 11. Thus, the flat panel 1 is placed on the bent panel 11.
Formwork panel 10 for constructing the cloth foundation is formed by connecting the two. On the other hand, if necessary, similar bent panels 11 are continuously provided in the horizontal longitudinal direction of the bent panel 11, and a flat panel 12 is attached to each of these upper portions. The bent panels 11 and 11 and the flat panels 12 and 12 that are continuous in the horizontal longitudinal direction may be joined with an adhesive or the like.

The upper part of the flat panel 12 is kept in contact with the contact piece 4a of the rising braided body 4 at a constant interval.
As shown in FIG. 1, fixed frames 17 are provided at several places along the longitudinal direction on the upper portions of both flat panel panels 12, and are fixed to the piles 18. The fixing frame 17 is for preventing the upper part of the flat panel panel 12 from opening outward due to the pressure of the poured concrete, and is attached so as to sandwich the upper parts of the two flat panel panels 12. Thus, the two flat panels 12 are firmly held with the contact pieces 4a, 4a of the rising braid 4 therebetween. However, instead of the fixing frame 17, the connector 13 may be attached to the upper part of the flat panel 12 to suppress the opening of the panel. In addition, the pile 18 is the flat panel 12, and thus the formwork panel 10.
This is to eliminate the entire shake of the. In this state, the space sandwiched between the formwork panels 10, 10 is filled with concrete. After the concrete is solidified, the fixing frame 17 is removed, the soil is returned to the root cutting groove 1, and the construction of the cloth foundation is completed. FIG. 4 is a perspective view of a fabric foundation constructed using the form panel 10.

Here, the bent panel 11 and the flat panel 12 constituting the form panel 10 are obtained by cutting a cubic foamable synthetic resin in accordance with the outer dimensions of a cloth foundation, and are used as a concrete form. In addition to having the function described above, unlike a normal formwork, it does not become detached after construction, and becomes a part of the cloth foundation by being integrated with the solidified concrete.

FIG. 5 is a side view of the foam block showing a method of cutting the bent panel 11 and the flat panel 12 from the foam block cut into unit dimensions. In FIG. 5A, unit dimensions (for example, W450 × H91
It shows how to cut out the bent panel 11 from the foam block 19 (0 × D1820 mm). In one embodiment, the height h1 of the bent panel 11 is 300 mm,
Since the width W is smaller than the width W (= 450 mm) of the foam block 19, a large number of the bent panels 11 can be cut out in the height H direction of the foam block 19. Therefore, the surplus portion R from the foam block 19 after cutting out the bent panel 11 was suppressed to about 10% of the volume of the foam block 19. FIG. 5B shows how to cut out the flat panel 12 from the same foam block 19.
In one embodiment, the height of the flat panel 12 is 450 mm
Since the width W is the same as the width W of the foam block 19, the flat panel 12 can be cut out without leaving an excess portion from the foam block as shown in the figure.

FIG. 6 is a perspective view showing another embodiment of the present invention. The figure shows the formwork panel of the present invention used for construction of a high foundation type fabric foundation. In this embodiment, a high foundation form panel is formed by stacking three flat panels 12 on the form panel shown in the previous embodiment, for example. In this embodiment, each flat panel 1
Also in the connection between the two, the connector 13 is used, and the flat panel panels 12 are sequentially stacked while being connected to each other by the connector 13.

As described above, the pair of bent panels 11
A plurality of pairs of flat panels 12 are connected to a plurality of connecting members 13 respectively.
By connecting using and accumulating the required number,
The cloth foundation of the normal height shown in FIG. 1 and the high foundation shown in FIG. 6 can be constructed by the same panel member. As mentioned above, although one Embodiment of this invention was described along drawing, the support structure of the form panel of this invention is not limited to the form panel used for construction of the said cloth foundation, but is another structural member. For example, the present invention can be applied to a formwork panel used for construction of underground beams, walls, and the like.

[0027]

The following effects can be obtained by constructing structural members such as cloth foundations, underground beams and walls using the support structure of the formwork panel according to the present invention. (1) Even when the height of the structural member to be constructed differs depending on the position of the slope, etc., by adjusting the number of stacked flat panels, the height can be adjusted without preparing a dedicated form panel corresponding to each height. Construction members can be constructed according to the requirements.

(2) Since one form panel is formed by joining a plurality of panels, the yield of cutting from a foam block cut in unit dimensions is improved, and the production efficiency can be increased, and the material can be increased. Waste can be reduced.

(3) Since one form panel is composed of a plurality of panels, each panel is relatively small, and the transportability and the workability are improved.
