Description

[Detailed Description of the Invention] The present invention relates to a reinforcement mounting bracket for attaching reinforcement to a paper form for forming a legal framework.

Conventionally, when forming a formwork for legal frame molding, 1
Alternatively, a plurality of paper formworks made of corrugated paper etc. are bent and connected to form a formwork unit having a rectangular shape, etc., and a large number of these formwork units are arranged on a slope at intervals, and the intervals between them are It was formed by connecting and fixing each formwork unit with reinforcement.

When attaching the reinforcement to the paper form, the ends of the reinforcement are bent into a U-shape, and the ends of the bent part are further bent at right angles to form a receiving part, and then The bent part was made to protrude outward from the through hole and received by the receiving part, and the wedge was inserted into the outwardly protruding bent part to fix it.
54-156922).

However, with this type of reinforcement installation, it is not possible to pivot the reinforcement at the attachment part of the paper formwork. As a result, the formwork unit could not be folded and had a bulky shape, making it inconvenient to transport to the site. For this reason, it is not possible to use formwork units with reinforcement arranged in advance, and the work involves arranging the formwork units on site, placing reinforcement at their intervals, and connecting and fixing each formwork unit. was required, resulting in poor work efficiency.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a reinforcement mounting bracket that is easy to manufacture and is capable of pivotally attaching reinforcement to a paper form.

According to the present invention, there is provided a loop metal fitting having a U-shaped bent part in the center and both ends bent in a direction perpendicular to the bent part to form a receiving part, and a groove fitted into the base of the loop metal fitting. and a fixing plate that is inserted between the paper form and the receiving part of the loop metal fitting when the bent part of the loop metal fitting is inserted into the through hole of the paper form.

When implementing this device, the end of the reinforcing bar is bent into an L-shape and inserted into the bent portion of the loop fitting protruding from the through hole of the paper form, so that the end of the reinforcing bar is attached so as to be able to pivot freely within the bent portion of the loop fitting.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, a reinforcement mounting fitting 1 according to the present invention is composed of a loop fitting 2 and a fixing plate 3. The loop fitting 2 is formed by bending an elongated metal plate, etc., and has a U-shaped bent part 4 in the center, and both ends are bent in a direction perpendicular to the bent part 4 to form a receiving part 5. , 5. In this embodiment, a notch groove 6 is formed at the base of the bent portion 4. On the other hand, the fixing plate 3 has a V-shaped groove 7 formed upward from the center of the lower side, into which the bent part 4 of the loop fitting 2 is fitted, and the upper edge part 8 is bent at an almost right angle. has been done. Further, the paper form 9 is provided with a through hole 10 into which the bent portion 4 of the loop fitting 2 is inserted. Furthermore, horizontal stripes 11 connecting the paper forms 9
The end portion of the bar is bent into an L-shape, and the horizontal bar 11 is welded to the vertical bar 12 arranged in a grid pattern.

In the above configuration, the bent portion 4 of the loop fitting 2
is inserted into the through hole 10 from the outside of the paper form 9, and the bent portion 4 protrudes from the through hole 10 inside the paper form 9.
Insert the L-shaped end of the transverse strip 11 into. Furthermore, on the outside of the paper formwork 9, the paper formwork 9 and the loop metal fittings 2
The fixing plate 3 is inserted between the receiving parts 5, 5, and the V-shaped grooves 7 are fitted on both sides of the bent part 4 of the loop fitting 2. Thereby, as shown in FIGS. 2 and 3, the L-shaped end of the transverse strip 11 is pivotally attached to the bent portion 4 of the loop fitting 2. Then, the fixing plate 3 clamps the bent portion 4 of the loop fitting 2 and moves the loop fitting 2 toward the outside of the paper form 9 to elastically connect the bent portion 4 and the L-shaped end of the horizontal strip 11. Bring it into close contact. Furthermore, the fixing plate 3 engages with the receiving parts 5, 5 of the loop metal fitting 2, and
Strengthens the receiving effect of

FIG. 4 shows a formwork unit 13 to which the reinforcement mounting bracket 1 described above is applied. This formwork unit 13 has a pair of paper forms 9, 9, each paper formwork 9.
Both end edges 9a, 9a are bendable. Three reinforcing bars 14 are arranged at predetermined intervals between these paper forms 9, 9, and these reinforcing bars 14 include two horizontal bars 11, 11 and two vertical bars 12, 12. are assembled in a grid shape, and the intersections are welded, and both ends of the horizontal reinforcements 11, 11 are vertically L.
It is made by being bent into a letter shape. And reinforcement bar 1
The L-shaped ends of the horizontal reinforcements 11 of No. 4 are pivotally connected to the paper formwork 9 by means of the above-mentioned reinforcement mounting bracket 1 according to the present invention. Therefore, the formwork unit 13 has horizontal strips 1
By pivoting the L-shaped end of 1 within the bending part 4 of the loop fitting 2, it can be folded freely.
It can be folded and stacked in large numbers and transported to the site. On the other hand, the vertical reinforcement 12 of the adjacent reinforcing reinforcement 14
Of these, a connecting rod 15 is provided which connects the formwork units 13 that are diagonally positioned as shown in FIG. 16, 16, and by inserting the annular portions 16, 16 into the vertical bars 12, 12, the longitudinal bars 12, 12 are connected in a spiral shape,
The formwork unit 13 can be fixed in an expanded state.

Then, as shown in FIG. 5, the formwork unit 13 is placed on a slope, and the edges 9a of the paper formwork 9 are successively connected by the connecting members 17 to form the formwork 18. can do. in this case,
A cross-shaped connecting fitting 19 may be provided at the portion where the formwork units 13 are connected in a cross-like manner, as shown by imaginary lines in the figure. 1 can also be used for attaching such a connecting fitting 19. In this formwork 18, reinforcement is provided to some extent by the reinforcing bars 14 and connecting rods 15 provided in the formwork unit 13, so that the reinforcement work can be greatly simplified.

Note that after the concrete or mortar is hardened by hitting the inside of the formwork 18 by means such as spraying, the fixing plate 3 is pulled out and the receiving parts 5, 5 of the loop fittings 2 are hammered. It is preferable to break it off by hitting it with a hammer or the like. In that case, since the notch groove 6 is formed in the bent portion 4 of the loop fitting 2, the breaking operation becomes easy.

As explained above, according to the present invention, there is provided a loop fitting having a U-shaped bent part in the center and having both ends bent in a direction perpendicular to the bent part to form a receiving part; The structure is simple because the bent part of the loop fitting is inserted into the through hole of the paper form, and the bent part protruding from the through hole is L-shaped. Simply insert the bent end of the reinforcement, insert the fixing plate between the paper form and the receiving part of the loop fitting, and fit the groove of the fixing plate into the bent part of the loop fitting. The installation work is easy because the struts can be attached. Furthermore, since the reinforcement is pivotally attached within the bent portion of the loop metal fitting, it is possible to use a foldable formwork unit with the reinforcement arranged in advance, as shown in Fig. 4, for example. This greatly simplifies reinforcement work.
