Description

Description: TECHNICAL FIELD The present invention relates to a formwork in which concrete is poured to construct a retaining wall, for example.

[Conventional technology]

Usually, when pouring concrete to construct a retaining wall, for example, a formwork is used. As the conventional technology of this formwork,
Panels are arranged in the left-right direction, the panels are piled up to a predetermined height on the arranged panels, and the set intervals of the facing panels are held by a separator, and vertical flaps and horizontal flaps arranged vertically and horizontally on the front side of the panel are described above. A washer is fitted to the connecting rod connected to the separator and is supported by a nut to be screwed in or a wedge to be driven.

[Problems to be Solved by the Invention]

Since the panels are stacked and the separators are attached to maintain the space between the panels facing each other and the vertical and horizontal flaps are arranged side by side to support the connecting rods that are connected to the separators, it takes a great deal of time to assemble, and it is impossible for an amateur to assemble. , A formwork carpenter is required.

Therefore, there is a problem that causes an increase in cost.

[Means for Solving the Problems] In order to solve the above problems, the present invention is a rectangular metal seat frame capable of adjusting the facing distance between the front and rear long parts, and the seat frame Adjustable expansion and contraction of a metal column member that supports the lower end on at least both ends of both elongated parts and connects at least the upper ends located in the front and rear with a connecting member, and detachable between the upper and lower front faces of this pillar member And a panel in which both end edges are fitted into and supported by the groove members of the left and right pillar members.

[Action]

For example, when building a retaining wall, the seat frames are arranged in series on the building line, and then two front and rear pillar members whose upper ends are connected by connecting members are erected on the seat frame.

After that, after mounting the grooved members on the entire length of the front surface of each pillar member and attaching it to the above pillar member, drop both end edges of the panel into the left and right groove members to support it, and then concrete between the panels. To place.

In addition, the panel and the channel will be collected after the cast concrete is hardened.

〔Example〕

In the figure, reference numeral 1 is a rectangle and front and rear long portions 2 and 2 which are parallel
It is a metal seat frame that can adjust the facing interval of the.

As a method of adjusting the facing distance between the long portions 2 and 2 of the seat frame 1, as shown in FIG. 6, the short portions 3 and 3 protruding inward from both ends of both the long portions 2 and 2 are shown. Are vertically overlapped with each other, and the predetermined holes 4 provided at equal intervals in the entire upper surface of the lower short portion 3 and the protruding shafts 5 provided at the lower end of the upper short portion 3 are fitted to each other. Although it has been performed, it may be performed by another method.

Further, at least both ends of the long portions 2 and 2 of the seat frame 1 are provided with metal pillar members 6 which can be expanded and contracted so as to stand.

In the case where the pillar 6 is erected, the standing protruding shaft 7 provided on the seat frame 1 and the hole 9 provided in the seat 8 at the lower end of the pillar 6 are fitted together in the illustrated case. You may employ methods, such as.

Further, in the method of adjusting the expansion and contraction of the pillar member 6, in the illustrated case, the middle of the pillar member 6 is cut off, and the plate-like body 10 protruding from the cut end of the one pillar member 6 is replaced by the back step 11 of the other pillar member 6. In addition, the holes 12 provided in the stepped portion 11 and the projecting shafts 13 provided in the plate-shaped body 10 are fitted together.

Also, at least the upper ends of the two pillar members 6, 6 located at the front and rear are connected.

Similar to the seat frame 1, in the above connection, the projecting plates 14 are projected from the column member 6 so as to vertically overlap with each other, and holes 15 provided at equal intervals in the entire length of one projecting plate 14 and the other projecting plate 14 are provided. It is designed to be fitted with the protruding shaft 16 provided on the.

Although only the upper end of the pillar member 6 is connected in the illustrated case, the upper end and the middle may be connected.

The total length of the surface of each of the above-mentioned pillars 6 has a removable channel 1
7 is provided.

The groove of the channel member 17 is provided on both sides, and the column member 6
The bolt 18 protruding from a predetermined position on the surface of the
Although the nut 20 is inserted through the through hole 19 and screwed into the bolt 18, the nut 20 may be detached, but it may be detachable by another detaching method.

Further, a bolt 23 with a holding plate 22 is screwed into the groove member 17 so that both ends of the panel 21 are fitted into the groove and then the back surface of the panel 21 is pressed against one side surface of the groove.

Although one of the pillar members 6 is inclined in the illustrated case, both pillar members 6 may be used vertically.

When a large number of panels 21 are added upward, both ends of the horizontal groove members 17 'are attached to the pillar member 6, and the upper and lower edges of the panel 21 are fitted in the upper and lower grooves of the horizontal groove members 17'. All you have to do is support it.

Next, a method of using the above-configured formwork will be described.

First, the seat frames 1 are placed in series on the construction line of the retaining wall that is made of discarded concrete, for example.

Further, a column member 6 is erected on each seat frame 1.

After that, both edges of the panel 21 are fitted into the groove of the channel member 17 from above and the panel 21 is dropped.

Then, concrete is placed between the panels 21.

When the cast concrete is hardened, the channel member 17 is removed from the pillar member 6, and the panel 2 is removed together with the channel member 17.
1 is collected and reused.

The seat frame 1 and the pillar member 6 are buried in concrete.

Also, when placing concrete, the openings at the ends between the panels are
It is closed by interposing a packing material (not shown) such as a plate-like body.

〔effect〕

As described above, by using the formwork according to the present invention, the vertical flaps and the horizontal flaps are arranged in the separators and the vertical and horizontal directions, and the panels facing each other without supporting the vertical flaps or the horizontal flaps on the connecting rod of the separators. Can be held.

For this reason, even an amateur can easily arrange the panels, and the construction period can be significantly shortened.

Further, since the facing interval between the parallel elongated portions of the seat frame can be freely adjusted and the standing column member can be expanded and contracted, the adjustment can be made according to the thickness and height of the concrete wall.
