として使用されているのが現況である。2. Description of the Related Art Conventionally, a general-purpose connecting hood structure for a vehicle such as a train is made of a round steel material for a main aggregate that is arranged in several rows as a chain-type hood frame system, and a plurality of them are arranged adjacent to each other. Alternately joining the central part and both ends to form a hood frame that is connected in a zigzag pattern and expands in a plane, and attach a synthetic resin processed cloth material to the hood frame, or multiple hood bones as one unit As a rectangular frame, the upper and lower sides of the frame are separately coupled to the upper and lower sides of the adjacent frames, and the whole is integrally coupled in a zigzag shape (V-shape) to form a frame body. It is known to crown a hood sheet to make a bellows hood construction. However, the reason why the above-mentioned chain-type hood frame system (hereinafter, referred to as chain-type hood frame) is used as the mainstream of the hood component is that the production is more time-consuming and more costly than the parallel-type hood frame system described later. Although it has a drawback that it causes, it is functionally effective in preventing drooping between the linked top bodies due to various movements of the vehicle body and the weight of the top body. The parallel type hood frame system (hereinafter, referred to as a parallel type hood frame) has a plurality of square ring-shaped hood bones as one unit, and independent frame bodies are juxtaposed adjacent to each other and arranged in parallel to each other. It is constructed by being crowned. Thus, in both the chain type and the parallel type hood frames, the hood sheets to be covered with these hood frames are usually laminated with vinyl chloride film sheets on both sides of the tarpaulin cloth as coarse coarse density fibers using synthetic fibers. In addition to waterproof cloth, synthetic fabric woven cloth with the required mixture of vinyl chloride resin is calendered to a calender roll for frictional adhesion to 0.7 m / m. It is the current situation.

幌強度の増大が計られる幌構成体を提案した。By the way, in the above-mentioned chain type hood structure, each hood bone of the hood frame is fitted with a hood sheet in conformity with the shape of a frame which is generally curved. That is, when the hood frame is first expanded in a flat shape and the hood sheet is stretched on the hood frame, the work is troublesome because a large number of covered hood sheets are cut and welded for each array hood. Met. In order to improve this, the present applicant has filed Japanese Patent Application Laid-Open No. 2-8505.
In No. 5, first, the hood sheet itself is fitted with a chain-like frame of the hood frame in which the bag-shaped through-passages capable of accommodating the hood bones of the hood frame arranged independently in several lengthwise directions on the laid hood sheet are accommodated. Is bent in the longitudinal direction so as to have a lateral cross section of Ω shape, and the lowermost portion thereof is welded to form an insertion path through which the hood bone can be inserted. We proposed a method of making a three-dimensional shape after forming a flat hood frame.
Further, in the case of the parallel type hood frame, it is assumed that the hood sheet can be easily covered with the chain type hood frame described above by the applicant of the present invention in the longitudinal direction on the outer hood sheet laid according to Japanese Patent Laid-Open No. 63-199169. The sandwiched hood frame in a state where the hood frames are independently arranged in parallel at predetermined intervals and the inner hood sheet is superposed and the hood frame made of the linear hood frame is sandwiched between the inner and outer hood sheets. We proposed a hood structure that has an extremely simple structure in which the sides of the hood are attached between the double layers of both hood sheets by welding the hood sheets together, and the hood strength is increased.

くいなどが改善課題とされていた。However, in the chain type hood frame described above, as shown in FIG. 6, different top and bottom sides of the top and bottom sides of the hood bone (7) are connected to each other. Supports to hold the gap between the components (13) from the outside by connecting metal fittings (not shown) so as to prevent the downward phenomenon due to its own weight at the center of the chain-shaped hood structure (15) and to maintain the height deviation. Configured. For this reason, it is effective for the strength of the connected hood itself and for preventing the descent, but its manufacturing process is troublesome and the hood sheet is stretched on the hood frame in a flat state as described above. Therefore, there is a problem in that manufacturing takes time and the manufacturing cost rises. Further, in the structure in which a plurality of hood bones are arranged side by side in the middle layer of the double hood sheet to sandwich and hold the hood frame, the work efficiency is improved because the hood sheet can be easily tensioned to the hood frame. Melting the side edges of the hood frame afterwards with the hood frame interposed between both hood sheets requires a considerable number of man-hours to carry out from the hood sheet covered with the hood bone. There was a need for rationalization in order to speed up the formation of the hood frame in the flat development before the conversion, and it was difficult to obtain the effect of suspending the hood body.

美感向上が図られることである。In a hood structure in which a hood frame of each conventional system is capped with a hood sheet, the hood bone has a large weight because the material thereof is a metal steel wire rod (round steel rod). There is great expectation that the drooping problem will be noticed and that a solution to this will be desired. In view of the above-mentioned circumstances, the present invention basically enables the canopy of the conventional canopy sheet to be covered very easily, and the work time for the planar development of the canopy frame and the subsequent three-dimensional canopy formation. By forming a hood structure with a parallel hood frame so that it can be shortened, manufacturing efficiency and total cost can be improved, and the hood sheet can be polymerized with light weight and high strength and high elasticity. Provided is a sheet composite for a connected hood, in which a hood frame is attached to a base material to prevent the connected hood from falling. One of the other purposes is to improve the beauty of the connected hood.

た。[Operation] The above technical means works as follows. That is, in the sheet composite for a linked hood of the present invention, the plain weave reinforcing fibers disposed in the intermediate layer of the hood sheet polymerization base material (1) are light, flexible and have a high strength aramid fiber lattice structure. The woven fabric is melted at several points at predetermined intervals along the longitudinal direction from the surface layers of the inner and outer hood sheets made of a thermoplastic vinyl chloride coating material sandwiched on both sides thereof. By heating to a temperature and pressing, the melted mutual surface layers come into contact with each other at the grid portion between the intersections of the lattice-like fiber structure, and the woven structure forming the yarn groups A and B has the above-mentioned inner and outer hoods. It is thermocompression bonded to the double-sided layer of the sheet. At this time, the vertical yarn reinforcing fibers (5) are adjacent to each other at predetermined intervals along the longitudinal direction of the hood sheet polymerized substrate (1) and are juxtaposed in the longitudinal direction to form unwelded points. That is, the hood groove portion (G) penetrating straight is formed. In this way, when the hood sheet polymerization base material (1) having the hood groove portion (G) is used as a composite for a connected hood, the hood formed as an intermediate layer portion of the hood sheet polymerization base material (1) is used. Since the hood bone (7) is inserted into the groove (G) and developed in a plane to stretch the integrated hood frame on the hood sheet, as shown in FIG. 3 and FIG. A parallel type hood frame can be developed in a plane simply by inserting the hood bones (7) along the formed adjacent straight hood grooves (G), and therefore, in the conventional staggered hood frame formation. Compared with this, the work is very easy and the time required for forming the hood frame is short. In the state in which the parallel type hood frame is three-dimensionally bent to form a square tubular connection hood by the conventional technique from the above-mentioned horizontal hood frame unfolded state and is installed as a vehicle connection hood as shown in FIG. The connecting hood sheet is formed by weaving the lattice-like yarn groups A and B having high strength in the length and width directions as embedded reinforcing fibers in the polymer layer of both the inner and outer hood sheets and enclosing them integrally. Since it is bitten into the surface hood sheets on both sides and thermocompression bonded, there is no misalignment of the woven structure, and since the woven fiber itself does not have bending, it is possible to sufficiently exhibit excellent mechanical characteristics in which stress is not concentrated Due to the above, the reinforcing effect of the hood sheet itself is extremely high, and the hood sheet is lightweight and has sufficient flexibility, so that the hood mounting frames can be firmly hung and normally held. In addition, by arranging a yarn group in which weft-weaving weft-reinforcing fibers (not shown) are woven and knitted in a belt shape at a position corresponding to the center of both side walls of the hood structure in the intermediate layer portion of the hood sheet in the vehicle direction. , Even when using a large diameter round steel rod for the hood, it was found that this was effective in loading the wire-shaped effect of the suspension bridge and reinforcing the drooping phenomenon by the weight of the connecting hood. It was

FIG. 1 is a plan view showing an example of the sheet composite for a connected hood of the present invention, (2) is an outer hood sheet,
(3) is an inner hood sheet, and (4) is a lattice-woven woven plain reinforcing fiber arranged in a sandwiched state between the inner and outer hood sheets (2) and (3). (1) is the above 3
It is a hood sheet polymerized substrate composed of a polymerized woven structure of various woven fabrics. In the above-mentioned hood sheet polymerized substrate (1), the hood sheets on both the inside and outside of (2) and (3) are hood sheets made by the above-mentioned conventional technique and rich in tensile strength and flexibility. Regarding the plain weave grid-like weave (4) sandwiched as an intermediate layer between the inner and outer hood sheets, (5) is a long fiber roving made of lightweight and high-strength aramid fiber heat-resistant organic elastic fiber. It is a multi-filament vertical warp reinforcing fiber. The reinforcing fibers are parallel to each other in one direction and are bundled together (for example, 0.66 m / m thick, 1500
De × 1500 De : A yarn group A formed by aligning a basis weight of 4618 gr / m 2 in a string shape and a horizontal yarn reinforcing fiber (6) formed by roving long fibers also made of a large number of heat-resistant organic elastic fibers are parallel to each other. And the yarn groups A and B having the yarn group B arranged in a string form are layered and composed of the vertical and horizontal yarn reinforcing fibers of the roving constituting them (5) and (5) Are woven and knitted in a lattice pattern at intervals S-1 and S-2 (usually 20 m / m) so that the directions are orthogonal to each other. It should be noted that it is desirable to increase the amount of the reinforcing fiber in the unit volume in order to obtain the strength and elastic modulus characteristics of the aramid fiber depending on the site where the hood sheet polymerized substrate (1) is used. In addition, weave spacings S-1 and S- which are made of the vertical and horizontal yarn reinforcing fibers
2 is determined according to the cross-sectional thickness of the reinforcing fiber used and the size of the hood groove (G) that is formed in the longitudinal direction on the hood sheet polymerization base material (1) and is formed later. Although the rovings are used as the filaments of the warp and weft yarn reinforcing fibers of the yarn groups A and B, rovings having an appropriate twist may be used as long as they do not impair the reinforcing purpose. The above-mentioned aramid fibers of the yarn groups A and B of the reinforcing fibers specifically have "Technora" of Teijin Limited, and the yarns of the roving are for the purpose of reinforcement (reinforcement) without bending to concentrate stress. The groups A and B are spaced apart from each other by spacings S-1 and S- in a direction in which their layered directions intersect with each other.
It is arranged at intervals of 2 and is woven in a checkered pattern with a very coarse texture. Here, the crossing angle between the yarn groups A and B does not have to be a right angle, and the other weaving method (not shown) may be used.
They may intersect at 0 °, 45 °, 60 °, and the width of the horizontal alignment of the horizontal reinforcing fibers (6) of the yarn group B is linked from the final constitution purpose of the hood sheet polymerized substrate (1). A large number of bundles are bundled in a specific portion of the hood, and the interwoven density of the above-mentioned lattice-shaped knitted fabric (4) may have some unevenness.

バラ状の角筒状幌に形成される。By the way, in order to construct a connecting hood sheet from the hood sheet polymerized base material (1) shown in FIG. 1, first, a thick outer hood sheet (2) is laid and then a grid made of high-strength aramid fiber. A three-layer hood sheet polymerization base material (1) in which a thin knitted woven fabric (4) is further covered and a thin inner hood sheet (3) is further laid thereon, and then a computer is formed on the surface of the polymer. A reference line indicating the hood frame is displayed by the following, and is set in a high-frequency welding machine (not shown) to set predetermined intervals S-1 and S-2 along the longitudinal direction from the surface layer of the polymerized substrate.
By heating and pressing several points at intervals, the welded portions (W) and (W) are formed between the layers, and the hood sheet polymerization substrate (1) having a desired shape is obtained. When heating and pressing the hood sheet polymerized substrate (1) described above, the aramid fiber itself in the intermediate layer is heat resistant and difficult to melt and hardly soluble, but the woven structure of the intermediate layer is in a lattice form. Since it is woven in, the vertical yarn reinforcing fibers (5) on both the inside and outside hood sheets
(5) A depressed pressing portion is formed between the insides, and in the pressing-corresponding portion, the vertical and horizontal reinforcing fibers (5) and (6) of the yarn groups A and B are both inside and outside hood sheets. It is thermocompression-bonded in the state that the bite is also buried in the surface and (W)
The unwelded portions of the welded portions of (W) are formed in parallel with each other in the longitudinal direction with hood grooves (G) having both ends opened for inserting the hood bone (7) described later. Yes (see Figure 2). When a connected hood is manufactured using the hood sheet polymerization base material (1) having the hood groove (G) thus formed, the hood sheet polymerization is performed as shown in FIGS. 3 and 4. The hood bone (7) is inserted into the hood groove (G) from the end of the base material (1), and the hood bone (7) is a tunnel-shaped long hood groove portion (G) and bulges (8) (9). ) Is firmly held in the composite hood sheet, and a horizontally developed parallel hood frame is formed between the layers in the hood sheet polymerization base material. It is formed into a bellows-shaped rectangular tubular hood that expands and contracts.

く、すぐれた強度を有するものである。FIG. 5A shows a state in which the above-mentioned rectangular tubular shape of the present invention is connected between vehicle bodies. In the present invention, when the hood sheet is capped on the side-by-side hood frame, it is linearly formed over the entire length of the hood sheet polymerized substrate (1) in the longitudinal direction and the hood bone (7) is inserted therein. Since the method is adopted, the formation of the hood groove (G) and the gripping of the hood bone by the hood groove become more tight and the production of the hood frame is simple, and compared to the conventional chain type hood frame called the staggered hood frame. Simplification of. Further, since the yarn groups A and B interposed in the intermediate layer of the hood sheet polymerization base material (1) use a large number of filaments of reinforcing fibers such as aramid fibers which are light, flexible and have high strength, the number of weaves in the knitted fabric is reduced. The characteristics of the aramid fiber can be effectively exhibited even with a very coarse lattice-like weave structure. That is, the aramid fiber as a reinforcing material for the hood sheet has a small degree of orientation distribution across its cross section and has excellent strength.

Even when it is laid via 2), since the lattice-like woven fabric layer of reinforcing fibers of the intermediate layer which is a constituent element of the hood sheet polymerization base material (1) and which is present in a sandwich form is entirely formed in a mesh shape. Since the yarn fibers are connected to each other and the top bone can be hung from the ceiling side and both sides of the hood structure, it can follow the vibrations caused by various movements of the car body and has good recoverability. It was also found that there is an unexpected functional effect that the hanging effect of the hood frame itself is further improved. This may be presumed to be due to the effect of suspending the rope steel wire in the suspension bridge, but the hood structure is integrated with the mutual displacement of the car body due to rolling and pitching of the car body. By elastically following the top body, the reinforcing effect of the top body is high, and therefore, the abrasion between the top bodies can be reduced and the durability can be improved.

分に発揮しうるものである。[Effect] From the above, the hood sheet polymerized base material of the present invention has a structure in which an organic elastic fiber having a high reinforcing effect on both the inner and outer hood sheet polymers is knitted and woven in a grid pattern in the intermediate layer to be embedded. Since a hood groove portion for arranging and horizontally expanding the parallel hood frame in the base material is formed and the hood bone is inserted into the hood groove portion, a quick parallel hood frame can be formed. Since the construction of the structure is achieved by an extremely simple structure, the work efficiency is significantly improved, the total manufacturing cost is reduced, and the purpose of preventing the hanging of the connecting hood structure is achieved. It is extremely advantageous as compared with the production method and can sufficiently exhibit excellent practical effects.
