Description

[Detailed Description of the Invention] The present invention relates to an improvement of a skip-type self-propelled multi-level parking lot with a cane.

The main structure of a self-propelled multi-story parking lot is often a large span structure with a length of about 16m, and the girders tend to be high. As the most effective means of reducing the beam size of this girder, as shown in Figure 1, an inclined support type cane 4 is inserted between the lower part of the column and the lower surface of the girder 3, and the upper part of the girder is A construction method has been implemented in which the lower ends are rotatably connected using pins 6, respectively.

However, this construction method has the following drawbacks.
That is, when entering or exiting the vehicle compartment or getting on or off the vehicle as shown in FIG. 3, the head, shoulders, etc. may hit the cane 4,
Contact may cause safety hazards.

As a countermeasure to this problem, as shown in Fig. 2, on the middle pillar 1 of the main framework of the main frame of a skip-type parking lot, beams 8 with an inclination angle of approximately 45° are installed alternately on the left and right near the nodes where the girders 3 are attached. A possible structure is to attach it to the According to this structure, the safety hazard caused by the pillar-type cane mentioned above can be eliminated without substantially impairing the mechanical effect of the cane, as shown in FIG.

However, this case has one mechanical drawback.

That is, in the case of the multi-story parking lot main frame frame shown in FIG. 2, as shown in FIG.
2 acts to the right, and the horizontal force from the right beam 3 is applied to the right, so a large bending moment 11 acts on the middle column 1. Therefore, a relatively large member is used for the center pillar even though it is pin-joined to other members.

The purpose of this invention is to take advantage of the advantages of multi-story parking lots with inclined support type supports while eliminating only their disadvantages. In a multi-story parking lot, a large span frame is provided in a direction perpendicular to the roadway, and the large beam 3 and outer column 2 that make up the frame are connected together, and the large beam 3 and the middle column 1 are rotated by a pin 6. Furthermore, the canals 5 and 8 are arranged between the lower surface of the girder 3 on both the left and right spans of the center column and the same node of the center column 1, and the beams 5 and 8 are connected to the girder 3 and the center column 1. This is a skip-type multi-story parking lot having a cane on the central pillar, which is characterized in that the two pillars are rotatably connected by a pin 6.

The invention will now be explained in detail by way of illustrated examples.

FIG. 5 shows an embodiment of the present invention, in which a large span frame is provided in a direction perpendicular to the roadway in a skip-type self-propelled multi-level parking lot, and the large beams 3 and outer columns 2 that make up the frame are installed. The girder 3 and the middle column 1 are connected together so that they can rotate with a pin 6, and the girder 3 and the middle column 1 are connected to the same node on the lower surface of the girder 3 on both the left and right spans of the middle column at the same node. 5, 8 are arranged, and each side cane 5, 8 and the main beam 3 and middle column 1 are rotatably connected by a pin 6, and the lower end of the left span side cane 5 is attached to the column base on the left floor. It is located in the department.

In the case of the multi-story parking lot shown in FIG. , 8 to the center column 1 cancel each other out.

In the case of the multi-story parking lot main frame shown in Figure 5,
As shown in FIG. 7, only the horizontal force from the right girder 3 acts on the middle part of the middle pillar 1 located on each floor on the left side, and the horizontal force from the left side cane 5 does not act, so the middle pillar 1 A small bending moment 13 acts on.

As a result, the amount of steel used can be reduced,
Furthermore, it is possible to reduce the area of the parking lot building, albeit slightly. In this case, the cane has a steep slope as shown by the broken line in Figure 4, so the safety issue is better than that of the conventional sloped support type cane, which has a slope of 45° as shown in Figure 3. Become.

In the conventional cane type shown in Figure 1, all nodes are pins, so the inclination angle of the cane must be close to 45° in order to effectively respond to horizontal forces. The reason why the framework is mechanically effective even with steep slopes like the one shown is that the outer columns and girders are rigidly connected.

Since the present invention is constructed as described above, the horizontal forces acting on the center column 1 from the left and right braces 5 and 8 cancel each other out, so that no large bending moment is applied to the center column 1. , and because the cane 5 can be made steep, the safety hazard is improved compared to the conventional diagonal column type cane 4. Therefore, it is a skip type multi-story parking lot having a diagonal column type cane. It is possible to obtain the effect of removing only the disadvantages while keeping the advantages of the above.
