Abstract

PURPOSE:To make assembling easy by constituting of a metal seat form, metal post members, channel bars and panels to be supported. CONSTITUTION:Shorter sections 3 and 3 to project inward each other from both ends of longer sections 2 and 2 overlap up and down. Metal post members 6 capable of adjusting are erected at least on the ends of both longer sections 2 and 2 of a seat form 1 and, at the same time, at least the upper ends of the post members 6 and 6 are coupled with each other. A removable channel bars 17 is provided to overall length of the surface of each post member 6. At that time, the channel bar 17 is such that bolts 23 with a hold-down plate 22 are screwed in one side of a channel after fitting the ends of a panel 21 in the channel so as to push the rear of the panel 21. According to the constitution, even an unskilled person can easily arrange the panel, an a construction period can be remarkably reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a formwork for constructing, for example, a retaining wall by pouring concrete.

[Conventional technology]

Usually, formwork is used when concrete is poured to construct a retaining wall, for example. The conventional technology for this formwork is
The panels are arranged horizontally, and the panels are stacked up to a predetermined height on the arranged panels, and the set spacing between the opposing panels is maintained using separators, and the vertical and horizontal patterns arranged vertically and horizontally on the front side of the panels are A washer is fitted onto a connecting rod connected to the separator, and supported by a screw-in nut or a hammer-in shaft.

[Problem to be solved by the invention]

Because the stacking of panels and the installation of separators to maintain the spacing between opposing panels, and the arrangement of vertical and horizontal flaps and support by connecting rods connected to the separators, assembly is extremely time-consuming and cannot be assembled by amateurs. , a formwork carpenter will be required.

For this reason, there was a problem that caused an increase in cost.

[Means to solve the problem]

In order to solve the above problems, the present invention provides a metal seat frame that can adjust the facing distance between the front and rear elongated parts that are parallel to each other in a rectangular shape, An expandable and retractable metal column member whose lower ends are each supported and whose upper ends located at the front and back are connected by a connecting member; and a channel member detachably attached between the upper and lower front surfaces of the column member; It consists of panels whose ends are fitted and supported by the channel members of the left and right columns.

[Effect]

For example, when constructing a retaining wall, seat frames are arranged in series on a construction line, and then two front and rear columns whose upper ends are connected by a connecting member are erected on the seat frames.

After that, a channel member is laid over the entire front length of each column material and attached to the above column material, and both ends of the panel are fitted into the left and right channel members by dropping to support them, and then concrete is placed between the panels. to be poured.

The panels and channels will be collected after the poured concrete has hardened.

〔Example〕

In the figure, 1 is a rectangular parallel long part 2.2
This is a metal seat frame that allows you to adjust the facing distance between the two.

As a method for adjusting the spacing between the long parts 2.2 of the seat frame 1, as shown in FIG. are stacked vertically, and predetermined holes 4 provided at equal intervals along the entire length of the upper surface of the lower short section 3 are fitted with protruding shafts 5 provided at the tip of the lower surface of the upper short section 3. Although we have tried to do this, other methods may also be used.

Further, on at least both ends of both long parts 2.2 of the seat frame 1, metal pillars 6 that can be adjusted to expand and contract are erected.

In the case shown in the figure, the method of erecting the pillar 6 is to fit the erecting shaft 7 provided on the seat frame 1 into the hole 9 provided in the seat 8 at the lower end of the pillar 6. Other methods may also be used.

Furthermore, the method of adjusting the expansion and contraction of the pillar material 6 is as follows: In the case shown in the figure, the pillar material 6 is cut off in the middle, and the plate-like body 10 protruding from the cut end of one pillar material 6 is connected to the back stepped portion 11 of the other pillar material 6. At the same time, the equally spaced holes 12 provided in the stepped portion 11 and the protruding shafts 13 provided in the plate-like body 10 are fitted together.

Further, at least the upper ends of both the front and rear members 6.6 are connected.

The above connection is achieved by making the protruding plates 14 protrude from the pillar material 6 so as to overlap vertically in the same way as the seat frame 1, and forming holes 15 provided at equal intervals along the entire length of one protruding plate 14, and holes 15 provided in the protruding plate 14 on the other side. This is done by fitting a protruding shaft 16 provided therein.

In addition, in the case of illustration, only the upper end of the pillar material 6 is connected, but the upper end and the middle part may be connected.

A removable channel member 1 is provided along the entire surface length of each pillar member 6.
7 is provided.

The grooves of the channel member 17 are provided on both sides, and the grooves of the column member 17 are provided on both sides.
The bolt 18 protruding from a predetermined position on the surface of the channel member 17
Although the bolt 18 can be removed by inserting it into the through hole 19 and screwing the nut 20 onto the bolt 18, other methods may be used to make it detachable.

Further, a bolt 23 with a presser plate 22 is screwed into the channel member 17 so as to press the back surface of the panel 21 against one side of the groove after fitting both ends of the panel 21 into the groove.

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

In addition, when adding a large number of panels 21 upward, attach both ends of the horizontal channel member 17' to the pillar material 6, and fit the upper and lower edges of the panel 21 into the upper and lower grooves of this horizontal channel member 17'. All you have to do is get involved and support them.

Next, a method of using the formwork constructed as described above will be explained.

First, the seat frame 1 is placed in series on the construction line of, for example, a retaining wall made of waste concrete.

Further, on each seat frame 1, a pillar member 6 is installed upright.

Thereafter, both edges of the panel 21 are fitted into the grooves of the channel member 17 from above, and the panel 21 is dropped.

Then, concrete is placed between the panels 21.

When the poured concrete hardens, the channel members 17 are removed from the pillar members 6, and the channel members 17 are removed from the panel 2.
1 is collected and reused.

Note that the seat frame 1 and the pillar material 6 are buried in concrete.

Also, when pouring concrete, the openings at the edges between the panels should be
It is closed with a binding material (not shown) such as a plate-shaped body interposed therebetween.

〔effect〕

As described above, by using the formwork according to the present invention, it is possible to arrange separators and vertical and horizontal flaps vertically and horizontally, and to form facing panels without having the connecting rods of the separators support the vertical and horizontal flaps. can be held.

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

Furthermore, since the distance between the parallel long parts of the seat frame facing each other can be freely adjusted, and the erected pillars can be expanded and contracted, adjustments can be made according to the thickness and height of the concrete wall.
