Description

[Detailed Description of the Invention] This invention relates to a connecting support fitting for connecting and supporting concrete formwork such as concrete formwork for housing foundations so as to position them one by one with respect to each other.

Conventionally, concrete formwork such as concrete formwork for housing foundations is connected to each other by a guide rod supported so as to be able to slide against the formwork, and a U-shaped guide rod fixed to the guide rod. A clamping fixture consisting of a clamping hook was used, and the vertical frame of the adjacent concrete form was supported by the clamping hook of the clamping fixture.

However, the straightness of the formwork assembled in this way is poor as it is, so in order to improve the straightness, it is necessary to use positioning rods such as square timbers to correct the misalignment of each formwork. Ta.

This idea was developed by focusing on the problems of the prior art mentioned above, and uses the guide rods of the clamping fittings that connect the concrete formworks to position the positioning rods of each formwork. Not only can you easily align the formwork that connects the formwork in rows, but you can also sandwich other members between it and the concrete formwork, making it even more convenient for manufacturing. An object of the present invention is to provide a connecting support fitting for concrete formwork that can be easily and inexpensively made.

Embodiments of the connecting support fitting of this invention will be described below with reference to the drawings.

First, the concrete formwork 1 using the connecting support fittings of this invention will be explained with reference to Figures 1 and 2.
Reference numeral 1 denotes concrete formwork for housing foundations, which is arranged facing each other at regular intervals from spacing fittings 2I fitted at both upper and lower ends, with vertical frame 3 at both left and right edges of the outer surface, and 1 at both upper and lower edges.
As each horizontal frame 4 is bent and formed, a vertical frame 5 is formed in parallel with the vertical frame 3 on its outer surface near the vertical frame 3.
is fixed.

Reference numeral 6 designates a through hole provided through the vertical frame 3 at both the upper and lower positions, and 7 represents a guide hole provided through the vertical rib 51 in correspondence with the insertion hole 6.

Reference numeral 8 denotes a guide rod supported so as to be rotatable and horizontally movable through the insertion hole 6 of the vertical frame 3 and the guide hole 71, and 9 is a tightening hook whose base end is welded to the guide rod 8f. The distal end portion is bent into a U-shape, and the center portion is slightly bent upward.

The guide rod 8 and the tightening hook 9 constitute a tightening fitting, and when connecting two adjacent formworks 1, the guide rod 8 is connected vertically to the other side of the adjacent formwork 1. When the frames 31 are inserted into the insertion holes 6 provided, the clamping hooks 9 clamp the vertical frames 3 adjacent to each other to tighten both forms 1.

Next, a first embodiment in which the connecting support fitting of this invention is used by being attached to the clamping fitting above the formwork 1 will be described with reference to FIGS. 1 to 5. This connecting support fitting 10 is made by making vertical incisions in the upper half of a single iron plate, and bending each section of the upper half to provide a different function.

That is, 10,000 l of the upper half has an engaging part 11 that can be engaged and detached from the guide rod 8 bent inward into an inverted U-shape, and the other l of the upper half is bent sideways. A holding part 12 is formed by bending it at a right angle f, having its outer end bent upward at a slightly obtuse angle, and having its upper end curved outward.

In addition, the lower half part has a contact part 13 bent inward in an L-shape.
is formed.

Now, to explain the operation of the connecting support fittings 10 configured as above, in the state 1 where the concrete formworks 1 are connected and fixed as described above, the engaging portions 11 of the fittings 10 are connected to each formwork 1. The guide rod 81 is engaged with the upper tightening fitting 1 and suspended.

Next, the positioning rod 14, such as a square timber or pipe, is driven in against the elastic force of the clamping portion 121 of each metal fitting 10.

Then, each formwork 1 is linearly aligned due to the elasticity of the clamping portion 12.

Moreover, the metal fitting 10 is urged to rotate around the guide rod 8 by the bullet f8Ht of the clamping part 12, and the tip of the contact part 13 is pressed against the outer surface of the formwork 1, so that one end is fixed to the ground f. A latching fitting 16 etc. for latching the other end of the buckle 15 is attached to the formwork 1.
By arranging the latching member 16 and the like between the contact portion 13 and the contact portion 13, the latching member 16 and the like are clamped and fixed between the two.

Next, the second embodiment is shown in Figures 1, 2, and 6 to 8.
Referring to FIG. 1, the connection support fitting 10 of this embodiment is different from the fitting 10 of the first embodiment in that the gripping portion 12 is inclined at an acute angle with respect to the abutment portion 13. The parts are almost the same.

Therefore, in the metal fitting 10 of this embodiment, the abutting position of the tip of the abutting part 13 against the formwork 11 is shifted outward compared to the first embodiment, so when fixing the base formwork 17 to the horizontal frame 4. It becomes effective at time f.

Next, the third embodiment will be explained with reference to FIG.
Once the contact portion 13 of 0 is bent outward, it is bent downward, and then further bent inward into an L-shape. Example 1 This example differs from the first example in that it has a function for fixing the formwork 17 for the base part.

However, this invention is not limited to the above-described embodiments, and may be modified as desired, such as changing the shape of each part, without departing from the spirit of the invention.

As described in detail above, the concrete formwork connecting support metal plate of this invention is made of a single metal plate, and the upper half of the metal plate is made with one cut at the top and bottom to separate the same parts. is bent inward in an inverted U-shape to form an engaging part, and the other part is bent outward and upward in an L-shape to form a holding part, and the lower half has its tip inward. Forming a contact part that bends in the opposite direction, it is possible to hold another member between the formwork and the contact part.1 From this, it is possible to use the guide rod of the clamping fitting that connects the concrete formwork. By connecting and erecting positioning rods to each formwork, multiple formworks can be easily aligned in a straight line, and other members can be sandwiched between them and the concrete formwork. Furthermore, since it has the effect of being easy and inexpensive to manufacture,
This is a practically preferable idea as a connecting support fitting for concrete formwork.
