Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guideway groove body for a magnetic levitation railway.

kJII for magnetic levitation railway levitation and running machine Fj't
it+, aS with a focus on economicalizing roadside installation η1f
Secondary coils are installed on the slab and side walls using a repulsion method.

In this case, it is preferable to use a non-magnetic material such as aluminum for the secondary coil and the like on the running path in order to avoid attraction force.

For the same reason, it is not desirable to use non-magnetic tensile material to reinforce the guideway, which is a concrete structure that supports and guides moving vehicles, and the corpse.

However, conventionally, the guideway structure has not been reinforced under such circumstances.

One of the reasons for this is that non-magnetic tensile materials such as glass fiber and carbon fiber are expensive for reinforcing the guideway structure, but an even more important reason is that these non-magnetic tension materials I will talk about the use of tension materials next! This is because there was a 4.

l) Reliable and economical anchorages for non-magnetic tension materials have not yet been developed.

, 2) A method for arranging tension members that can reinforce the guideway structure with non-magnetic tension members has not been clarified.

3) It was unclear how to assemble members that could significantly reduce magnetic drag when non-magnetic tension material was used for the guideway structure.

The first problem is that if an economical anchorage that could be used for reinforcement had been developed, it would be appropriate to use the conventional reinforcement method using the lower girder method, but since it has not yet been developed, it is difficult to use this type of reinforcement. Therefore, this becomes a bottleneck for application to Kiteway.

Embodiments of the present invention will be described below with reference to FIGS. 1-3.

As shown in the figures, the present invention has features 1 and r in which gutter side walls for magnetic levitation railways are joined by a bonding material q, and Figures 11.2.3 are all guideway II It shows the structure of the corpus luteum, and shows that the horizontal slab/ and the lateral slab are joined at the junction A.

In each figure, non-magnetic tension material 3 is arranged in a grid pattern parallel to the edge of each member i! lL! This indicates that the

In Fig. 1, a joining hole is arranged for joining the members.General steel material can also be used. t.

Figure 2 shows vertical non-magnetic tension material 3 placed on the side wall.
Although the case where they are bonded is shown, they can also be bonded using a separately added bonding material.

In Fig. 3, the horizontal force acting on the side 1jG2 is received by a buttress 7, and the side wall 7 is connected to the horizontal slab 1 by a joint material.

Here, the non-magnetic tension material 3 is arranged in two directions parallel to the edge of the slab, and prestress can be applied to the concrete by a pre-tension method or a post-tension method, but from the manufacturing cost perspective, it is difficult to It is desirable to use a pre-tension method in view of the fixability of the magnetic tension material 3 using a fixing device. Note that there is no restriction on partially reinforcing the edges of the member with steel materials such as reinforcing bars.

When the pre-tension method is used, it is possible to perform mass production in a factory and contribute to cost reduction.

The above-mentioned non-magnetic tension material 3 is made of glass fiber or carbon fiber wire material, and by using these materials, in addition to reducing magnetic drag, it also reduces heel salt air, etc. compared to PC steel materials such as high carbon steel. It has the effect of being able to provide sufficient iJ atrocities even in the presence of it. Incidentally, the wire rod made of F, F/R bar is a non-conductor and does not generate magnetic force based on υ electromagnetic balance. In addition, the above-mentioned horizontal slab l and the side wall.

With the above structure, the side wall λ and the horizontal slab are structurally connected, and the load generated by the load (1>1) is increased and the load bearing capacity is increased.

Next, FIG. 3 shows a structure in which a buntresque is provided between the horizontal slab 1 and the side wall 1, so that the horizontal load acting on the side wall can be transmitted to the horizontal slab 1 by the buttress 7.

This configuration not only has the effect of reducing the vertical reinforcement of the side wall 2, but also has the effect of reducing the tension material 3 of the horizontal side wall by shortening the spacing between the buttresses 7.

Note that this does not preclude the use of the above-described crimp bonding and the buttress 7 in combination.

Next, by locally forming a mineral layer at the junction point 6 between the horizontal slab l and the side wall, it not only facilitates the placement of the joining material at the joint part, but also minimizes the magnetic field line density of the superconducting magnets loaded on the vehicle. It can be possible to join at a certain point,
Even if a general magnetic @ material is used as the bonding material from the viewpoint of economy, the magnetic drag caused by it can be significantly reduced.

The effects of the above configuration can be summarized as follows.

(1) Since the guideway structure is divided into two parts, a side wall and a horizontal slab, it can be precast, which facilitates the application of non-magnetic tension material using the pretension method, and significantly improves productivity.

(2) In addition to the fact that the side walls and horizontal slabs are reinforced with non-magnetic tension material, the joining position can be magnetically reduced even if a normal magnetic copper phase is used for joining them.
