Abstract

In order to solve this problem, it is necessary to solve the problem of the double-floor supporting stiffener which is currently used, and to use it for the new and existing installed supporting columns So that the effect as a reinforcing material is ensured.
The existing dual floor support stiffener has a high cost structure by using the structure, composition and materials different from the characteristics of the existing double floor flooring material. Due to the low number of joining parts and the low floor (15cm ~ 50cm) There was a difficult problem. As a result of the shaking table test, it is very dangerous for the product to make some construction convenient because its reinforcing characteristic is extremely weak and its role as a reinforcing material is extremely dangerous.
The present invention has developed a dual-floor supporting stiffener having a structure capable of satisfying the above-mentioned problems while satisfying the double-floor supporting stiffening property.
A special reinforcing head 120 having a head shape to be used in a conventional double floor capable of being inserted at the side of the double floor floor support 110 so as to be combined with the existing double floor supporting pillars has been developed, A stringer 101 (frame) is joined to reinforce the support.
The reinforcing head 120 of the present invention is different from other reinforcing materials in that the developed head 120 has a conventional shape of a conventional head 103. However, in a situation in which a heavy equipment 113 on the double floor 100 is operated, The stringer 101 can be inserted from the side of the preformed stanchion, and the conventional stringer 101 can be inserted in four directions like the conventional head 103, And the direction of the stringer 101 is the direction coinciding with the lateral direction of the double floor panel 102. [
The advantages of the general double-head 103 and the stringer 101 are low cost through mass production, and it is proved that the installation and use are simple with a simple structure, and the strength against the durability and vibration of the product is verified, It has been proven that it has been used for over 20 years in Japan, the United States, etc.
The present invention was invented utilizing this point, and the inventor invented the improved method to realize the low cost and proved to be safe in the shaking table test.

Description

Holding a raised floor reinforcement {

The present invention relates to a dual floor standing stiffener, and more particularly, to a method of joining with a shape of a portion joining with a stringer (frame) supporting a double floor is similar to a head which is generally used, A special reinforcing head for reinforcing a dual floor floor supporting structure having a structure that can be used in combination with the floor is developed and a reinforcing head and a stringer are installed in a multi-layer structure in the same direction as the four directions of the panel, And to reinforce the double-floor support for fastening the reinforcement head to the support by firmly fastening the support to the support.

Generally, in the data center, the communication room, and the computer room, a double floor is installed and is used as the moving path of the cold air movement and the cable. Recently, earthquakes have been frequent, and the response of double floors to earthquakes has begun to attract attention. Due to the fact that the floors sometimes collapse due to an earthquake, they are used by using earthquake-resistant floors or by reinforcing existing double floors .

However, the above earthquake-resistant double-wall flooring or conventional double-floor supporting stiffening material has some disadvantages and is restricted in use.

Once, the price of earthquake-resistant double floors is twice as expensive as the existing floor, making consumers hesitate to apply them.

Most of them are expensive, and some of them are inexpensive. However, when the shaking table test is performed, the effect of the stiffener is doubtful. Also, considering that the height of the double-floored pillars that interfere or reinforce the movement path of cables and cable trays is usually as low as 15cm ~ 50cm, which is a very difficult condition for the operators to work, Despite of this easy structure, the stringer (frame) must be reinforced diagonally, the anchor should be installed on the floor, or bolted fastening is required when installing reinforcements. to be.

As such, the disadvantages of currently applied products are obvious, and consumers are having a lot of difficulties in selecting them.
