Description

[Detailed Description of the Invention] [Industrial field of application] This invention is to protect slopes such as slopes facing highways and various facilities constructed by the open cut method or steep slopes that may collapse. The present invention relates to a connector for a formwork used when creating a work.

[Conventional technology]

As shown in FIGS. 2 and 3, the conventional formwork used when forming the slope protection work is a pair of left and right side plates 1 using metal laths, clamp wire nets, etc. The frame 2 and the frame 2.

The connecting frame 2 is fixed by welding or the like along a long horizontal bar 4 made of a steel bar along the lower side of an upward U-shaped lower horizontal bar 3 called a lower stirrup. A short horizontal bar 5 made of a steel bar is integrally fixed to the upper ends of the lateral horizontal bars 3 by means such as welding.

The outer ends of the horizontal bars 4 and 5 are projected from both sides of the lower horizontal bar 3 and are rotatably engaged with the side plate 1 as a connecting portion 6.

The rotatable connecting portion 6 is bent into a ring shape, and the ring-shaped portion is rotatably engaged with a vertical wire member forming the side plate 1, or the side plate 1 is penetrated through the ring-shaped portion. An arbitrary structure such as driving a retaining member into the annular portion is adopted.

The above-mentioned upper horizontal bars 5 are left and right, and their inner ends are opposed to each other with a space so that a slight opening 7 is formed.
Further, both ends of the left and right swash bars 8 made of the same material as the upper horizontal bar 5 are fixed to the inner end of the upper horizontal bar 5 and the intermediate portions on both sides of the lower horizontal bar 3 by welding or the like.

The upper end of the swash bar 8 is projected above the upper horizontal bar 5.

The above-configured formwork B is transported with the connecting frame 2 along the side plate 1 with the both side plates 1 approaching each other, and the both side plates 1 are opened and installed at the on-site formwork installation place.

The form B is arranged vertically and horizontally, and the opposite ends are gathered in a plane cross shape.

[Problems to be solved by the device]

In order to maintain the gathering of the plane cross-shaped gathering ends of the formwork installed vertically and horizontally, the side plate adjacent edges of each formwork are connected using a wire or the like.

Therefore, an object of the present invention is to provide a connecting tool of a mold for forming slope protection construction which can connect the collecting ends of the molding extremely easily.

[Means for Solving the Problems]

In order to achieve the above object, the present invention comprises a plate-like member bent in a plane L shape, and a hook provided so as to project downward from both sides of the plate-like bent part of the back surface. is there.

[Action]

The opposite ends of the formwork, which is brought to the site and installed vertically and horizontally, are assembled into a plane cross shape, and the plate-like bodies are superposed on the outer surfaces of the abutting ends of the side plates of the formwork, and the plate-like body is meshed with the side plates. While penetrating each hook, slide the plate downward, fix the plate to the side plate through the hook that fits into and engages with the lower edge of the mesh, and opposes both side plates through the plate. Connect the ends.

〔Example〕

Hereinafter, a connector according to the present invention will be described with reference to the accompanying drawings.

In the figure, A is a connector.

As shown in FIG. 1, the above-described connecting tool A is provided on both sides of the plate-shaped body 11 bent in a plane L shape and the back-side bent portion of the plate-shaped body 11 so as to project downward. It consists of hooks 12 and.

In the illustrated case, the hook 12 cuts the wire in the longitudinal direction of the wire mesh forming the plate-shaped body 11 by pressing above the portion intersecting with the wire in the lateral direction, and presses the wire above the cutting point by pressing. Although it is made to project while being bent and formed in a hook shape on the back surface of the body 11 (the surface that overlaps the side plate surface of the mold frame described later), the hook may be fixed by a method other than the above, for example, welding.

Although two hooks 12 are provided in the upper portion and the lower portion in the illustrated case, the hooks 12 may be increased or decreased depending on the size of the plate-shaped body 11.

Further, a slope protection construction frame B using the above-mentioned connecting tool A
As shown in FIGS. 2 and 3, is composed of a pair of left and right porous side plates 1 using a metal lath, a clamp wire mesh, and the like, and a connecting frame 2 connecting the both side plates 1.

The connecting frame 2 is fixed by welding or the like along a long horizontal bar 4 made of a steel bar along the lower side of an upward U-shaped lower horizontal bar 3 called a lower stirrup. A short horizontal bar 5 made of a steel bar is integrally fixed to the upper ends of the lateral horizontal bars 3 by means such as welding.

The outer ends of the horizontal bars 4 and 5 are protruded from both sides of the lower horizontal bar 3 and are rotatably engaged with the side plate 2 as a connecting portion 6.

The rotatable connecting portion 6 is bent into a ring shape, and the ring-shaped portion is rotatably engaged with a vertical wire member forming the side plate 1, or the side plate 1 is penetrated through the ring-shaped portion. An arbitrary structure such as driving a retaining member into the annular portion is adopted.

The above-mentioned upper horizontal bars 5 are left and right, and their inner ends are opposed to each other with a space so that a slight opening 7 is formed.
Further, both ends of the left and right swash bars 8 made of the same material as the upper horizontal bar 5 are fixed to the inner end of the upper horizontal bar 5 and the intermediate portions on both sides of the lower horizontal bar 3 by welding or the like.

The upper end of the swash bar 8 is projected above the upper horizontal bar 5.

The above-configured formwork B is transported with the connecting frame 2 along the side plate 1 with the both side plates 1 approaching each other, and the both side plates 1 are opened and installed at the on-site formwork installation place.

The form B to be installed is arranged vertically and horizontally as shown in FIG. 4, and the opposite ends are gathered in a plane cross shape.

Thereafter, as shown in FIG. 4 and FIG. 5, the plate-like body 11 is superposed on the outer surface of the abutting portion of the side plate 1 of the form B, and each hook 12 is penetrated into the mesh of the side plate 1.

Since the hook 12 is slightly shorter than the mesh length of the mesh in the longitudinal direction, it can be easily penetrated.

Next, while sliding the plate-like body 11 downward, the plate-like body 11 is fixed to the side plate 1 via the hook 12 that fits and engages with the lower edge of the mesh, and the opposite end of each side plate 1 is inserted through the plate-like body 11. To connect.

In addition, after the form B is installed, a plurality of lower main reinforcing bars 21 are inserted from the openings 7 and arranged at appropriate intervals on the bottom side of the lower horizontal reinforcing bar 3,
Further, a plurality of upper main reinforcing bars 22 are arranged on the upper horizontal bar 5.

After that, a plurality of downward U-shaped upper horizontal bars 23 called upper stirrup are arranged so that both sides thereof are outside the upper main reinforcing bars 22 on both sides and overlap with both sides of each lower horizontal bar 3.

After that, concrete is placed in the form B.

〔effect〕

As described above, when the opposite ends of the side plates that are assembled in the shape of a plane cross of the formwork are connected using the connection tool according to the present invention, the dislocation movement of the assembly end of the formwork is stopped and the assembled state is maintained. Therefore, the pitch division of the beam becomes reliable.

Moreover, since the hooks penetrate through the mesh of the side plate, and the plate-like body is slid downward to engage the hook with the lower edge of the mesh, the opposite ends of the side plates can be connected. It eliminates the need for troublesome work.

Further, even if there is a gap at the opposite end of the side plate, the gap can be closed by the plate-shaped body that overlaps the side plate.

Therefore, the pouring concrete is prevented from flowing out.
