つた。(Prior Art) Conventionally, welding type rubber screens have been made by forming transverse rope-like bodies (cored) at both ends of the screen into an L-shaped cross section, as disclosed in, for example, Japanese Utility Model Publication No. 55-4072. Because the screen was sandwiched between the iron hook and the holding plate and tightened with bolts and nuts, the vibration and bending of the screen caused wear and tear of the horizontal rope-like element near the hook, breakage due to wire breakage, and the coating of the horizontal rope-like element. When the elastic body and the tensile body embedded therein are pulled out from the elastic body, the tension of the screen is loosened and the horizontal rope-like element (hereinafter referred to as
There was a problem that the rope itself (simply referred to as the horizontal rope) could slip out from between the hook and the presser plate on which it was held.

する。 Therefore, as a countermeasure against such rope breakage, it may be possible to increase the strength by increasing the thickness of the tensile material buried inside the rope, but this would not only increase costs as the amount of covered elastic material would be reduced, but also the rope In addition, when the diameter of the rope is increased, the entire rope becomes thicker, increasing costs due to material loss and causing clogging problems. On the other hand, as a measure against the wear of the rope during hooking,
The tensile members of the horizontal ropes at both ends of the screen are exposed, the bottom plate of the L-shaped cross-section hook is placed on top of this, a liquid elastic material is cast onto this, the tensile member and the bottom plate are fixed and integrated, and then the bottom plate is fixed and integrated. There is a method of casting and solidifying a liquid elastic material containing an abrasion resistant compound to form a two-layered elastic material in the hook part, but since this is made of two-layered elastic material, it increases the cost and makes the casting process difficult. This results in poor adhesion between the two elastic layers.

破断などの事故はまぬかれない現状である。 In addition, in a screen having a hook configured as described above, there is also a method of pasting a vertical elastic sheet or rope on the horizontal rope at the hook edge.This method improves the abrasion resistance at the hook edge, but In addition to requiring a lot of welding time and increasing costs, the attached sheet and rope are not integrated with the hook and the elastic body in which the tensile body is embedded, but are attached separately, which can cause problems due to bending fatigue of the horizontal rope. strength decrease, wire breakage,
Accidents such as breakage are inevitable.

めた点にある。(Means for Solving the Problems) That is, the feature of the present invention is shown in FIGS. As t, cored rope-like elements having arbitrary shapes such as circular, elliptical, quadrangular, and polygonal in cross section and having their peripheries covered with polyurethane elastic body 3 are arranged in parallel in the horizontal direction, and the above-mentioned In a rubber screen in which cored or non-core rope-like elements with a cross-sectional shape are arranged in parallel in the vertical direction, vertically and horizontally orthogonally crossed, laminated and crossed, and the intersecting parts are joined by heat welding, the horizontal rope-like elements are A narrow abrasion-resistant sheet 4 is pasted on the upper surface of both ends of the body, and the tensile members T at both ends of the transverse rope-like element body 1 are exposed, and one side of the tensile member T is staggered. The bottom plate 5 of the hook 5 has an L-shaped cross section and has a large number of through holes H arranged in the bottom plate 5.
A, a part of the sheet 4 is embedded and integrated into the polyurethane elastic body R together with the hook bottom plate 5a and the exposed tensile body T, and two abrasion-resistant sheets 4' are also placed on the upper surface of the central part of the screen. . The point is that the horizontal rope-like element is clamped and fixed by tightening with bolts.

る。 In the above, the screen center is not the center in the strict sense, but refers to the middle part of the screen width. Therefore, if the screen is wide, the presser plate 6 and the presser angle may be affected not only at one location but at multiple locations. This includes tightening and fixing according to 7.

フツク係止部が得られる。 Then, on the upper or lower surface of this tensile member T, an iron hook 5 having an L-shaped cross section with staggered through holes H provided in the bottom plate 5a is arranged in close proximity to the bottom plate 5a. A long and thin thermoplastic polyurethane sheet 4 is placed on the horizontal rope 1 at a position slightly shifted from the exposed part G of the tensile member T at both ends (after the tensile member T is exposed, adhesive is applied to the exposed part and then dried). By adhering the sheet 4 vertically, and casting liquid polyurethane (thermosetting) on top of it so that the sheet 4 is partially buried in the width direction and curing, the exposed resistor is removed as shown in Figure 1. A part of the sheet 4 is buried in the polyurethane elastic body R together with the tension body T and the bottom plate 5a of the hook, and at the same time, liquid polyurethane flows into the through hole H of the bottom plate 5a to exert an anchoring effect, and both ends of the horizontal rope 1 are A strong hook locking portion is obtained in which the exposed tensile member T, the bottom plate 5a of the hook, and a portion of the sheet 4 are adhesively integrated.

なつている。 Note that installing the screen usually requires tensioning of the horizontal ropes, and a horizontal crown is required to obtain sufficient tension, but when the screen is wide, the screen can be attached as shown in Figure 4. The horizontal rope in the center is clamped from above and below by a steel holding plate a and an L-shaped angle b and tightened with pincer bolts to form multiple crowns to maintain tension in the screen, prevent it from flapping, and prevent the processed material from shifting to either side. It's getting old.

イドへの偏りを防止できなくなる。 At this time, the crown is formed by the support of the cushion rubber attached to the tip of the support frame c below the screen, but if there is no presser plate in the center,
Since only one crown is formed, the crown angle (degree of curvature) becomes large, and the tension of the horizontal ropes is insufficient, making it impossible to prevent the screen from flapping and from shifting to both sides of the processed material.

ロープの断線、破断の問題もある。 From the above-mentioned point of view, the screen of the present invention is equipped with a center holding plate at the center of the screen like a normal screen, and the iron holding plate of the horizontal rope at the center of the screen is connected directly from above and below with an L-shaped angle. Because they are in contact and tightened through pincer bolts, there are problems with wear of the horizontal rope near the holding plate, breakage of the horizontal rope due to bending, and breakage, similar to the case with the horizontal rope at the hook portion, as described above.
従つて本発明は、このスクリーン中央部に対し

This figure shows a cored or coreless longitudinal rope-like body (vertical rope), and a predetermined interval is provided except for the vertical rope 2, which is the width for placing a presser plate or sheet. Next, two abrasion-resistant urethane sheets (thermoplastic) 4', 4' are placed in the gap between the vertical ropes 2, 2 in the vicinity of the vertical ropes 2, 2 on both sides.
4' is welded and pasted onto the horizontal rope 1 so that a part of it is inserted under the center holding plate 6.

バースクリーンとしても頗る効果的である。(Effects of the Invention) As described above, the rubber screen of the present invention has a cored rope-like body of various cross-sectional shapes, with a tensile body made of low elongation and high strength stranded wires, and polyurethane coated around the tensile body. They are arranged in parallel in the horizontal direction, and on top of them are cored rope-like bodies coated with polyurethane having the same cross-sectional shape as the horizontal ropes, or coreless rope-like bodies made only of polyurethane elastic bodies, which are arranged perpendicularly in the vertical direction and are laminated and crossed. Then, the horizontal rope tensile members on both sides of the rubber screen, whose intersections are joined by heat welding, are exposed, and wear-resistant urethane sheets are pasted on the upper surface near both ends of the horizontal ropes, and a staggered sheet is placed over the entire exposed tensile member. A cross section L having a plurality of through holes arranged in a shape
The bottom plate of the letter-shaped hook is brought close to the bottom plate of the hook, along with the exposed tensile material, and a part of the sheet is embedded in thermosetting polyurethane and fixed and integrated to form a strong hook attachment part and the upper surface of the horizontal rope in the center of the screen. It is a rubber screen that has a center presser part in which two wear-resistant urethane sheets are pasted vertically at a predetermined interval, and a center presser plate is fastened and fixed with bolts, partially spanning the sheets. The edges of the hook and the center part of the screen are reinforced with a reinforced structure that includes sheets, which significantly improves abrasion resistance, and also prevents the horizontal rope from loosening and breaking due to bending, extending the life of the screen. It can be greatly increased in size and is extremely effective as a rubber screen for not only lumps such as ore and crushed stone but also granular materials and granular materials.
