Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire truss serving as a core material of panels used for roofs, ceilings, floors, walls, etc. of houses, a method for manufacturing the same, and a panel using the wire truss as a core material.

Regarding wire truss panels, Tokuko Sho 52-3208
No. 53-19984, No. 53-32777, and Japanese Unexamined Patent Publication No. 52-84846, etc., the Tsuiya truss used as the core material of these
Since the wires do not form a regular triangle, it cannot be accurately called a truss, and it is also insufficient in terms of strength. Therefore, the wire truss panel itself, which uses this truss as a core material, is not structurally superior. Moreover, even when manufacturing this truss, it was not possible to manufacture it continuously and efficiently due to its structure.

The present invention was devised for the purpose of providing a wire truss and a wire truss panel that do not have the above-mentioned drawbacks, and also for the purpose of continuously and efficiently manufacturing the wire truss. It is characterized by multiple wires that are alternately bent in mountain folds and valley folds in parallel, and flat wire mesh is welded to the top and bottom of the wires.
Moreover, the wire truss panel is made into a flat plate by loading a porous body into the wire truss. In addition, in the method of manufacturing a Tsuiya truss, multiple wires are fed out in parallel and bent alternately in mountain folds and valley folds, and flat wire meshes previously formed above and below are folded. The feature is that, while being fed out, the contact portions of the plurality of wires and the upper and lower two wire meshes are brought into bath contact.

Embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in Figs. 1 and 2, the wire truss structure according to the present invention is made by bending a plurality of relatively thin wires Il+ with a diameter of about 2 to 3 mm in order of alternating mountain folds and valley folds. They are arranged in parallel in the longitudinal direction, and flat wire meshes (8) as shown in FIG. ), (
+b) are fixed by welding. The wire mesh (5) in the illustrated example is an ordinary wire mesh in which the vertical lines (2) and the horizontal lines (3) are orthogonal to each other in the shape of a base opening, and each intersection point is fixed by welding.

In this way, a wire mesh (8), (A) in which a plurality of wires 11) bent in alternating mountain folds and valley folds are arranged in parallel between the two upper and lower wire meshes (8) and (A) ) Since a regular triangle is formed from K, it can be said to be a true truss, and even though the wire i11 used is relatively thin K, it is excellent in terms of strength.

The truss truss according to the present invention appears to be the same as that formed by sequentially folding a wire mesh into mountain folds and valley folds using a press (Japanese Patent Publication No. 15003/1983), but it is actually However, there are the following differences between the two.

That is, if a flat wire mesh is formed by sequentially folding a mountain fold and a valley fold using a press, the large size wire mesh will be distorted by the bending, and it cannot actually be used as a commercial product. The larger the wire mesh, the stronger this tendency was, and it was difficult to obtain the desired Tsuya truss. However, in the case of the wire truss according to the present invention, the relatively thin Tsuya (1) is sequentially folded in a mountain fold and a mountain fold, respectively. Since they are alternately bent, there is no distortion at all due to the bending, and the product can have a high commercial value.

The truss according to the present invention is used as a core material of a panel (B) as shown in FIG. 7, for example. That is, the wire truss according to the present invention is loaded with porous materials such as plastic foam, lightweight cellular concrete, mineral fibers (including glass fibers), perlite, and various types of plastics (vermicelli, perlite, gypsum). By doing so, a panel (B) can be obtained.This panel (B) has extremely high strength because the core material is the truss truss according to the present invention, and is suitable for use in membrane structures and housing. It is suitable for roofs, ceilings, floors, walls, and as a finishing material. It also has excellent moisture-proof, heat-insulating, and sound-insulating properties.
It is expected that there will be a large demand for it in the future for use in heat insulation, messenger warehouses, whirlpool chambers, and sound insulation walls for roads, and its characteristics can be exploited to develop a wide range of other uses.

Next, an embodiment of the method for manufacturing a wire truss according to the present invention will be described with reference to FIGS. 3 to 6.

A relatively thin wire fi+ with a diameter of about 2 to 3 mm wound around a plurality of coil stands (4) is successively suspended horizontally and parallel to each other through a pair of upper and lower rollers (5), (5).

In front of the pair of upper and lower rollers T5+ and +51, there are two pairs of bending and welding devices (Q) at the front and rear, and the upper and lower rollers T5+ and +51 are provided with two bending and welding devices (Q) at the front and rear. By moving downward, each wire 1 is paid out sequentially.
1) is bent into a wave shape.

A flat wire mesh (5) as shown in FIG.
1), when they come into contact, the suppressing member (6) and the pedestal (7) are instantaneously energized to weld the wire mesh (5) and each of the wavy wires Il+. That is, a pair of upper and lower pressing members f61
and the pedestal (7+,!=Ii), the action of bending the straight wire (1) alternately in mountain folds and valley folds, and the wire mesh (5
) and Tsuya Ill (!:). In FIG. 4, the pressing member (6) is shown after it has been moved up or down from the position indicated by the chain line.

Clamping means +8+, (
9) are provided as an upper and lower pair, and the suppressing member (8) of the clamping means reciprocates (moves up and down). As shown by the arrow in FIG. 6(a), the pressing member (8) is adapted to clamp the wheel 11 when it descends to the position indicated by the solid line.

The reciprocating movement of the suppressing member (8) is preferably performed by an air cylinder with a high operating speed, and the air cylinder is
It is preferable that the solenoid valve is opened and closed by a control device (not shown) having a 0.6 timer that can be set in units of scale. For example, after the pressing member (8) moves forward (downward) as shown by the solid line in Fig. 6(b), the right suppressing member (6) moves forward (downward) as shown in Fig. 6(b). The left suppression member (6) moves forward (upward), and then, as shown in the same figure (c), seconds later, the left suppression member (6) moves forward (upward).
If the control device is set so that the wire truss moves downward), high-speed production of 90 cycles or more per minute is possible, and wire trusses can be manufactured accurately and efficiently.

Note that the timing of the backward movement of the suppressing member (8) of the clamping means is at the same time as the forward movement (lower 1liIJ) of the left pressing member (6), as shown in FIG. 6eJ, or after that. good.

Then, as shown in FIG. 6(C) from the state shown in FIG. !l1II) Then,
The wire mesh after welding is moved forward by a certain distance (from the chain line position to the solid line position) as shown in FIG. ) performs the next forward motion.

By repeating this operation, the wire mesh after welding is moved forward by a certain distance (one pitch).

Then, if necessary, the truss can be cut into predetermined dimensions to obtain a truss of a predetermined size.

According to the manufacturing method by [Kihatsu], seven wire truss panels can be manufactured continuously and efficiently, and in particular, since the straight wire is folded alternately in mountain folds and valley folds, It is possible to completely eliminate the distortion that occurs when a conventional flat wire mesh is folded alternately into mountain folds and valley folds, resulting in a product of extremely high quality.

Another advantage is that there is no need for a powerful bending device required to bend a large wire mesh as in the past.

In the embodiment, a porous material injection device is provided in front of the clamp devices f8) and f9), and its nozzle 1)
), the porous material is jetted out, and the porous material is sequentially filled into the truss shown in FIG. Then, by cutting this into regular dimensions using a cutting device (E), a panel (B) as shown in Fig. 7 is obtained.
can be obtained.

Examples of porous materials include plastic foam materials, lightweight cellular concrete, mineral fibers (including glass fibers), perlite, and various plastics, as described above. In this case, lightweight aggregate for concrete (AL) is used in the porous body for the purpose of reducing costs.
A) Natural lightweight aggregate or industrial waste (for example, blast furnace slag) may be mixed in. Desired materials may be mixed in to improve performance such as adhesion and water-stopping properties.

In addition, in continuously manufacturing the wire truss (A) according to the present invention and the panel (B) using the wire truss as a core material, the flat wire mesh (5) is rolled in the form of a roll as shown in FIG. 3(a). If you roll it up and unroll it in sequence,
Extremely efficient.
