JPS6013612Y2 - Fixing structure of reinforcing wire mesh for lightweight cellular concrete - Google Patents

Description

[Detailed description of the invention] This invention is particularly suitable for thicknesses of 5011r! This relates to the fixing structure of reinforcing wire mesh for lightweight cellular concrete, which aims to accurately and efficiently place the reinforcing wire mesh in the center of the product or at the required thickness when manufacturing thin products of about fL. .

Metal lath used as reinforcement for lightweight aerated concrete (ALC) usually has strands of 0.5 to 1.5 m.
m, eye size 10-50rlr! n, is lightweight and easy to bend, so if you want to place it correctly in the product, you will need to use a large number of support rods and use special clips to fix the metal lath and support rods (Utility Model Publication No. 49-375). It has been practiced to bend the metal lath and insert a support rod into it (Utility Model Publication No. 49-1403), or to sandwich a metal lath between two support rods.

However, it has been pointed out that this method requires time to fix the metal lath and has problems with the accuracy of the metal lath arrangement.

In view of these circumstances, the present invention focuses on the fact that the strand portion of the metal lath is thin and easy to cut, and the free end of the cut portion can be easily bent, and the cut portion of the metal lath is efficiently wound around a support rod. The aim is to provide a fixing structure for reinforcing wire mesh for lightweight aerated concrete, in which the attachment is fixed and the metal lath is attached with improved accuracy. It is characterized in that the vicinity is cut at a plurality of places, and the free ends of the cut parts are wrapped around the support rod.

EMBODIMENT OF THE INVENTION Hereinafter, the fixing structure of the reinforcing wire mesh for lightweight cellular concrete according to the present invention will be explained using the embodiment shown in the drawings.

FIG. 1 is an explanatory diagram showing the procedure for obtaining the fixing structure according to the present invention. First, the strands of the flat lath 1 constituting the reinforcing wire mesh are cut at multiple locations near the support rods 3.
The two strands of the cut portion 2 are formed into free ends (see figure b), and finally the two free ends are wrapped around the support rod 3, either as is or bundled, and fixed by providing a fixing portion 4. (C in the same figure).

The position at which the strands of the flat lath 1 constituting the reinforcing wire mesh are cut does not need to be particularly limited, but if the diameter of the support rod 3 is thick, it can be shortened, and if the diameter of the support rod 3 is thin, it can be shortened. Considering the rigidity of the diameter of 3, usually 5 to 12rrr
Coupled with the fact that it is In, when trying to fix the support rod 3 at a position where the strands cross in the vertical direction of the flat lath 1 (the position shown in Figure 1), fix the next cross on either the left or right. It is sufficient to cut the upper and lower two strands at the position where the strands have crossed to form free ends.

In addition, it is sufficient that the cut portion 2 is fixed at least at two locations above and below the support rod 3, but if there is slack in the central portion in the height direction, a fixed portion 4 is also provided at the central portion. All you have to do is set it up.

Furthermore, in order to prevent the flat lath 1 constituting the reinforcing wire mesh from slipping down, a hook 5 with a height of about 3 mm is installed on the upper part of the support rod 3 to hook the cross part of the flat lath 1, as shown in FIG. 1C. The support rod 3 may be provided so that it can be rotated 90 degrees and removed.

When using the fixing structure according to the present invention for manufacturing lightweight aerated concrete, as shown in FIG. Inject ALC mortar into 6 and
After the mortar is foamed and solidified, it is removed from the mold, and the central part of the flat lath 1 is cut with piano wire and cured in an autoclave to obtain a lightweight foamed concrete product.

Note that a notch with the cut portion 2 will be created in a part of the flat lath 1 that constitutes the reinforcing wire mesh, but this is only a local problem and will impair the rigidity and impact resistance of the product. Never.

As described above with reference to the embodiments shown in the drawings, according to the fixing structure according to the present invention, the reinforcing wire mesh can be placed accurately and efficiently with a simple fixing structure.

[Brief explanation of drawings]

Figures 1a and 1c are explanatory diagrams showing the procedure to obtain the fixing structure according to the present invention, and Figures 2a and 2b are explanatory diagrams showing the state in which the fixing structure according to the present invention is used in a product. Flat lath, 2 is the cutting part, 3 is the support rod, 4 is the fixed part, 5
is the hook, and 6 is the formwork.
