Description

[Detailed description of the invention] The present invention relates to the manufacture of a new metal cap.

Waterproofing is an important issue for buildings in order to protect them. For this purpose, metal caps are installed on building structures (Panabet, etc.), but in the past, caps were installed using aluminum alloy or other metal caps placed at appropriate intervals on the structure 1, as shown in Figure 1. The mold member 2 is fixed in advance using an anchor or a set screw 3, and then a cap 4 is placed on it.

By the way, the conventional cap 4 is made of aluminum and is extruded to have a wall thickness of at least 2f1. Therefore, when attaching an item having such a thick wall, it is carried out to fit it into the mold member 2 by pressing it from above the mold member, as shown in FIG.

On the other hand, because the conventional ones are thick as mentioned above,
The material and manufacturing costs are high, and since the fitting is done by pressing from above, the protruding dimension e of the flanges 4a and 4a' formed at both ends of the cap is made too large. This makes it virtually impossible to fit the structure 1 and the flanges 4a, 4aI, because a gap is not covered by the flanges 4a, 4a'. If this happens, the problem will be that wind and rain will enter through the chain as shown by the arrow.

The present invention aims to solve the above problems,
An example of implementing the present invention will be described below based on the drawings.

FIG. 3 is a schematic plan view of an apparatus for manufacturing a thin metal cap according to the present invention. Reference numeral 5 denotes the main body of the apparatus, and a large number of rollers 6 are installed on one side wall surface 5a in the longitudinal direction for sequentially bending the edge portions of the thin metal plate as described below while it is traveling. On the other hand, the distance between the opposing rollers 6'' installed on the other side of the roller 6'' can be changed as appropriate by operating a handle. Specifically, a plate 7 with a large number of rollers 6'' attached thereto. is engaged with the handle shaft 8a placed across the device main body 1 in the [1] direction, and the handle shaft 8a is rotated in the direction of arrow e by rotating the handle 8b clockwise or counterclockwise.
Alternatively, it is moved in the f direction. In this case, 9 and 10 are guide shafts, and the side plate 7 is the shaft 9.
10. G.
G" is a stopper for locking.

Although not shown in this drawing, the rollers 6 and 6' are each composed of a pair of upper and lower rotating rollers, and both end edges S and S' of the thin metal plate 11 are successively rotated in the vertically opposing gap (not shown). By being inserted and rotated, both ends a of the part 11
Positions at appropriate intervals from s and s' are bent as needed. That is, in the illustrated example, the roller group of block A performs the first bending at a desired constant distance from the edge S, and the roller group of block B performs the next folding, and the following blocks In roller group C, bending (/4
However, in the roller group of block D, the bending is performed sequentially to form a combined L-shaped and U-shaped folded portion.

On the other hand, the same is true for blocks A1B' on the other side, which are bent by the roller group of each block, (r') (0
) is performed to form an L-shaped bent portion.

In the above-mentioned bending operation, the hand (v8b) is rotated as appropriate depending on the width l of the thin C metal plate 11, and the distance K between the opposing sides is changed as appropriate to obtain the desired size and shape.

Although not shown in the drawings, the left and right rollers 6 and 6' are equipped with drive wheels, chains, drive motors, etc. for forced rotation. flash metal plate 11
is 0.61111I-0.8Wll for aluminum material.

For colored galvanized iron materials, Q, 4 y - Q, 5 v
tm is 0.3 sin to 0.8 for vinyl chloride steel plate.
m is 0.4 fl to 0.8 fl for acid-resistant coated steel plate.
0.3 mrt for vnO and colored galvanized iron
Those of t to Q and 3 tzytt are respectively used.

FIG. 4 shows a molded plate of the cap 12 produced as described above.

FIG. 5 is a perspective view of the mold member 13 used in the present invention, and as seen in the drawing, the outer shoulder portion is formed into a diagonal shoulder f with an inclined wall surface at a constant angle. Installing a cap that allows the work to be done easily is extremely effective.

FIG. 6 shows an installation state diagram.

First, as shown in A, mold members 1 are placed in advance at appropriate intervals (usually 50 CIN to 60 CIR) on the upper surface of the structure (Panabet) 1.
3 using the setscrew 14. Therefore, hold the L-shaped bent part of the molded Kasagi 12 with your hand,
The other end is hooked onto the lower side of the diagonal shoulder f of the mold member 13 and pulled downward to be crowned.

Next, the L-shaped curved υ part side of the crowned percent tree 12 is held at intervals of about 50 cN using a gripping tool, specifically, the hanging wall m of the mold member near the middle position of the adjacent mold members. This is done so that the protrusion P is formed and a partial fixation is achieved.

FIG. 7 is an explanatory cross-sectional view of another example of a cap 12' fixed in place, and in this example, the setscrew 15 is fixed so that the tip of the bent portion, which is a combination of an L-shape and a U-shape, remains immovable. This is an example in which it is used and fixed to the structure 1 side. Note that various decorative wall materials can be attached to the front side of the structure 1 as appropriate.

According to the present invention, a thin metal plate of about 0.81 nI - 0.8 ff is used, and by using roller means organized in several groups, both edges in the width direction are bent as desired. It is easy to manufacture compared to those manufactured by conventional extrusion molding, and because it is well-known, the material cost is low and the overall cost is low. Furthermore, since the cap itself is lightweight, the installation process is easy and quick, and it greatly contributes to improving work performance.
