Description

Description: BACKGROUND OF THE INVENTION The invention of this application relates to an earthquake-resistant three-dimensional warehouse, in particular, a high-rise rack collides with an external structure during a strong earthquake to damage or destroy the high-rise rack, the external structure, and the like. About a three-dimensional warehouse that can prevent earthquakes.

2. Description of the Related Art Conventional three-dimensional warehouses are classified into two types: a separate type in which an external structure and a high-rise rack are separated and independent, and an integrated type in which an external structure and a high-rise rack are integrated. In many cases, a separation-independent type is often used for reasons such as ease of manufacture.

The separation-independent three-dimensional warehouse is configured such that a high-rise rack is self-supporting in a building serving as an external structure, and a gap is formed between a peripheral wall of the building and the multilayer rack. The gap is set to a size such that the multilayer rack does not collide with the peripheral wall even when the building and the multilayer rack swing during a strong earthquake.

Problems to be Solved by the Invention Separable and independent large-scale three-dimensional warehouses for temporary storage are often constructed along the harbor, but from the structural viewpoint, etc., the following (i) ) Or (iv).

(I) Since the ground on which a large-scale three-dimensional warehouse is constructed is along the harbor, there are many soft grounds, and the predominant period of the ground during an earthquake is long. On the other hand, when the three-dimensional warehouse to be constructed is increased in height and scale, the natural cycle of the three-dimensional warehouse becomes longer. Therefore, the possibility that the natural period of the three-dimensional warehouse coincides with the predominant period of the ground increases. Therefore, in order to avoid collision between the high-rise rack and the external structure during an earthquake, it is necessary to increase the gap between the high-rise rack and the external structure. This can be very expensive in terms of space utilization.

(Ii) In the event of a strong earthquake, if a collision occurs between the high-rise rack and an external structure in the large gap, the acceleration will be shocking,
This may cause the stock to collapse.

(Iii) In a three-dimensional warehouse for freezing or refrigeration, if the high-rise rack collides with an external structure due to an earthquake and damages the insulation, etc., once it starts operating, repair work should be performed at room temperature. , Resulting in damage to the inventory. For this reason, it is necessary to provide a configuration that can prevent damage or destruction of the high-rise rack, the external structure, and the like due to collision between the high-rise rack and the external structure.

(Iv) A high-rise rack in a freezer or refrigerated three-dimensional warehouse is constructed by striking cinder concrete on a relatively soft heat-insulating material and fixing the column base of the high-rise rack to this, so that the structure is controlled. Problems and construction restrictions. Further, in order to firmly fix the column base of the high-rise rack, the lower part of the column base penetrates the heat insulating material, and is fixed to the structural foundation below the heat insulating material. Heat is transferred through the pillars, making it difficult to prevent heat treatment to block heat transfer from outside the warehouse.

SUMMARY OF THE INVENTION The present invention is to solve the above problems (i) to (iv). The problem to be solved is to increase the utilization of space in a three-dimensional warehouse and to damage or destroy high-rise racks and external structures. An object of the present invention is to provide an earthquake-resistant three-dimensional warehouse that prevents a high-rise rack and an external structure from colliding with each other or causes the stock to be dislodged, and that is structurally stable and easy to construct.

Means for Solving the Problems The modes of vibration of the high-rise rack and the external structure during an earthquake have been elucidated by experiments, and the high-rise rack and the external structure have large amplitude vibrations (primary and secondary vibrations). Shaking) occurs. The primary and secondary vibrations for the high-rise rack and the external structure are illustrated as follows:
FIG. 2 and FIG.

The antinode of the vibration mode of the high-rise rack and the external structure in the primary vibration, that is, the part where the amplitude of the swing is large,
As shown in FIG. 1 (A), it is located at the top of the high-rise rack and the external structure. Therefore, when these primary eigen-synchronous components are greatly included in the periodic component at the time of the earthquake,
A collision occurs at the top of the high-rise rack.

The antinode of the vibration mode of the high-rise rack and the external structure in the secondary vibration, that is, the portion where the amplitude of the swing is large,
As shown in FIG. 2 (A), the high rack and the external structure are located at about 1 / of the height. If these secondary eigen-synchronous components predominate in the periodic component of the seismic motion, a collision will occur at about 1/3 of the height of the high-rise rack.

According to the present invention, as shown in FIG. 1 (B) and FIG. 2 (B), a three-dimensional warehouse is configured to exhibit a behavior in which a high-rise rack and an external structure are integrated during a strong earthquake, thereby solving the above-mentioned problems. Is what you do.

In a three-dimensional warehouse in which a high-rise rack is independently provided in an external structure, a portion of the high-rise rack where the vibration of the high-rise rack shakes greatly during an earthquake and a portion of the external structure corresponding to the portion are provided. A strut member is disposed between the strut member and the high-rise rack or the external structure, and a gap is formed between the receiving surface of the strut member and the external structure or the high-rise rack. It is located in an earthquake-resistant three-dimensional warehouse that is configured to exhibit a behavior in which the high-rise rack and the external structure are integrated through the structure.

In a three-dimensional warehouse for freezing or refrigeration, installing a strut member on a high-rise rack where the amplitude of the shaking during an earthquake is large facilitates the heat treatment of the external structure, but the three-dimensional warehouse is not for freezing or refrigeration. In the above, a strut member may be attached to a portion of the external structure corresponding to a portion of the high-rise rack having a large amplitude of shaking during an earthquake.

As the portion of the high-rise rack to which the tension member is attached, where the amplitude of the shaking at the time of the earthquake is large, a portion corresponding to the antinode of the vibration mode in the primary or secondary vibration of the high-rise rack is selected. The part corresponding to the antinode of the vibration mode in the primary vibration and the secondary vibration of the rack is selected.

The strut member may be configured such that a vertical force due to its own weight acts on the high-rise rack or the external structure.

The strut members prevent bending moments, shear forces, etc., from being transmitted to the external structure or high-rise rack. In other words, at the time of strong earthquake, the strut member comes into contact with the external structure or the high-rise rack, and transmits only the horizontal force to the external structure or the high-rise rack, so that the high-rise rack and the external structure exhibit an integrated behavior. .

The strut member includes a support member and a receiving member, and is configured to buffer the movement of the receiving member using an elastic body such as a spring. The receiving member is movably supported by the supporting member,
An elastic body such as a spring may be interposed between the support member and the receiving member, or an elastic body such as a spring may be interposed between the support member and a part of a high-rise rack or external structure to which the support member is attached. You may make it. Increasing the receiving surface of the receiving member reduces the stress at the time of collision.

If there is a pillar at the part of the external structure facing the pillar of the high-rise rack, a strut member is placed between the pillar of the high-rise rack and the pillar of the external structure, and the external structure facing the horizontal member of the high-rise rack is placed. If there is a horizontal member such as a beam in the portion, a strut member may be arranged between the horizontal member of the high-rise rack and the horizontal member of the external structure.

The size and number of the strut members are appropriately determined according to the scale of the high-rise rack and the external structure.

In a three-dimensional warehouse for freezing or refrigeration, the outer structure is lined with relatively soft heat-insulating material (insulation material).
The receiving surface of the strut member has a large area, and the movement of the receiving member is buffered by a spring material such as a spring so that the heat insulating material is not damaged.

The quake-resistant three-dimensional warehouse according to the present invention includes a tension member disposed between a portion of the high-rise rack having a large amplitude of the swing of the high-rise rack at the time of the earthquake and a portion of the external structure corresponding to the portion. The high-rise rack or external structure is mounted so that there is a gap between its opposing members, and the high-rise rack and external structure are integrated via a strut member during a strong earthquake. The behavior in which the high-rise rack and the external structure are integrated can be exhibited.
