Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improved structure of a support fitting for receiving and supporting the bottom side of a side panel of a concrete formwork.

[Conventional technology]

Conventionally, as a support metal fitting that can easily adjust the height of the side panel with a concrete formwork, the applicant has
The one described in 63-28742 was devised. The one described in this publication has a screw rod protruding from one side of a rectangular base plate made of a metal plate fixed to the ground such as concrete, and a height adjusting nut is screwed onto the screw rod. At the same time, an L-shaped receiving plate is loosely fitted to the screw rod, the receiving plate is placed on the nut, and the bottom surface of the side panel of the concrete form is placed between the vertical surface of the receiving plate and the screw rod. In addition, it has a structure in which it is supported, and a plurality of nail holes are formed in the other side of the rectangular substrate. Then, concrete nails are inserted into the respective nail holes and driven into the ground to fix the support fittings.

[Problems to be solved by the device]

The conventional metal support thus constructed has no problem in that the original purpose of use can be sufficiently achieved. However, after the concrete poured into the formwork has hardened, when removing the formwork, the concrete nails driven into the support fittings are pulled out, but since the concrete nails are firmly attached to the substrate, It is not easy to pull out only the nails, and since it takes time, the workability deteriorates.Therefore, I had to insert a tool such as a crowbar between the board and the ground and pry the board together to pull out the concrete nails. However, the substrate is twisted and deformed by being twisted by a burl or the like, or it is damaged by tearing a nail hole or the like, and it can be used only in a so-called disposable type and cannot be reused, which is extremely uneconomical.

Therefore, an object of the present invention is to provide a supporting metal fitting that can be reused repeatedly so as to solve such conventional problems and can be economically used.

[Means for Solving the Problems]

In order to achieve such an object, the support fitting of the present invention comprises a screw rod standing on a horizontal base plate, a height adjusting nut is screwed onto the screw rod, and an L-shaped receiving plate is loosely fitted thereto. Placed on the upper surface of the nut, a pair of strip plate-shaped standing wall members provided on both sides of one end of the base plate with receiving walls facing inward at the rear end with a constant space on substantially the same horizontal plane as the base plate. Then, the rear end receiving wall side of each standing wall member is fixed to the substrate, and the connecting plate extending between the compatible wall members is fixed to the lower surface of the front end portion to fix the bottom surface between the compatible wall members and the front end front surface of the member. The structure will be opened.

[Action]

The support metal fitting is arranged at a predetermined position on the upper surface of the concrete ground, and the holding plate made of wood or the like having a width substantially equal to that between the pair of standing wall members and longer than the standing wall members is inserted from the front end front surface. The fittings are fitted so as to be hit against both the receiving walls, and in this state, the support bracket is fixed by nailing the portion surrounded by the compatible wall members of the pressing plate and the outside thereof.

Then, after the concrete poured into the form has hardened, to remove the support fittings, pry the press plate with nails etc. to remove it, and the concrete needle will come out with it. It is possible to remove the standing wall member without deforming or damaging it and to use it again without any flaw.

〔Example〕

An embodiment of the support fitting of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a horizontal substrate made of a thin metal plate, a screw rod 2 is vertically provided on the upper surface of the substrate, and a nut 3 is screwed onto the screw rod 2. 4 is made of a metal strip and has a side L
It is a receiving plate formed by bending in a letter shape. A through hole 5 is provided in a horizontal piece 4a of the receiving plate, which is loosely fitted in the screw rod 2 and is placed and held on the upper surface of the nut 3. In addition, the vertical piece 4b of the receiving plate 4 and the screw rod 2
The interval is set to be substantially equal to the plate thickness of the side panel 6 described later.

Reference numerals 7 and 7 denote a pair of standing wall members that are arranged in parallel on both sides of the front end of the substrate 1 at regular intervals. Each of the standing wall members 7, 7 is made of a metal strip having a predetermined width, and the rear end portions thereof are bent inward at right angles to each other and provided with a receiving wall 8 fixed to the front end edge of the substrate 1, and It has a planar shape in which each front end portion is provided with a positioning wall 9 which is bent outward at a right angle. Further, a connecting plate 10 extending between the compatible wall members 7 and 7 is fixed to the lower surface of the front end portion, and a bottom surface surrounded by the substrate 1 and the connecting plate 10 and the compatible wall members 7 and 7, and the front end of the compatible wall members 7 and 7. Openings 11 and 12 are formed on the front surface of the part.

13 is a holding plate to be fitted between the compatible wall members 7 and 7, which is made of wood such as veneer, and the front end of which is struck from the opening 12 to the outside with the tip abutted against the receiving walls 8 and 8. It is the size to put out.

The use of the support fitting thus configured will be described.
When arranging the side panels 6, 6 as concrete formwork with a certain distance as shown in Figs. 4 and 5, they are supported at appropriate positions facing each other on the concrete ground as shown in Fig. 2. Disposing the metal fittings, fitting the holding plate 13 between the compatible wall members 7, 7 of each supporting metal fitting, and the end of the pressing plate 13 is made to strike against the receiving walls 8, 8, and the compatible wall members inside and outside the connecting plate 10. A plurality of concrete nails (14) are driven into the holding plate (13) surrounded by 7,7 and driven into the ground (15) to fix the respective support fittings.
Then, the bottom side 6a of the side panel 6 is sandwiched between the vertical piece 4b of the receiving plate 4 and the screw rod 2 to be supported, and the nut 3 is rotated to adjust the height of the side panel 6. Furthermore, in order to prevent the concrete that has been driven in from the lower gap of the side panel 6 on both the left and right sides of the support metal from flowing out, the side wall of the standing wall member 7 and the positioning wall 9 are used to stop the ends of the piers 16, Deploy. As a result, even if the concrete pushes the pier 16 outwards, the pier 16 has both ends positioned on the positioning wall 9
It is stopped by and does not move. Moreover, a holding plate that is fixed even if the side panel 6 is pushed by concrete.
13 Since the receiving walls 8 and 8 are received by the front end face, the entire support fitting does not move. Then, after the concrete poured into the formwork is hardened, if the pressing plate 13 is removed by prying it with a bar, the concrete nails 14, 14
... can be removed easily, and the pair of standing wall members 7 and 7 can of course be removed without any deformation or damage to the substrate 1, and the support metal can be removed. Therefore, only the holding plate 13 can be removed. If replaced, the support fitting can be reused repeatedly.

[Effect of device]

As described above, the concrete panel side panel support metal fittings of the present invention can be efficiently removed, especially when the support metal fittings are removed after the concrete has been poured, because the concrete needles can be easily removed by removing the holding plate. It is possible to remove the support metal fittings and formwork, and it is possible to remove the support metal fittings without any deformation or damage without scratches, so that they can be reused repeatedly, which is a great economic advantage. To have.
