2. Description of the Related Art In recent years, there has been an increasing number of water tanks having a composite plate structure in which a steel sheet is used as a form material and concrete is filled therein.

[0003] When the water storage tank has such a structure, the waterproofness and the earthquake resistance are improved and the strength is also improved.
There is an advantage that the water tank can be made thinner than a water tank with a reinforced concrete structure, and a water tank with a large water storage capacity can be constructed in a site having the same area.

However, in the construction of a water tank having such a composite plate type structure, a steel form is manufactured at a construction site, concrete is poured into the form, and the steel form is required to have a required height. Since the work of adding concrete and placing concrete is repeated, the respective construction periods of assembling the steel formwork, curing the concrete, and welding the joint part of the steel formwork are added as the construction period, so the overall construction period is However, there has been a problem in that the length of the building has increased and the construction cost has increased.

[0005] In order to solve such a problem, the water tank is divided into several parts, and a synthetic plate-type steel-concrete composite segment (a segment in which a steel shell is filled with concrete) is fitted to each part. After manufacturing concrete in a factory and curing concrete, a composite segment is brought to a construction site, a plurality of composite segments are combined vertically and horizontally, and a joint is welded to construct a water storage tank.

[0006]

However, the construction of a water storage tank using the above-described synthetic version synthetic segment has the following problems. (1) It takes time to connect the segments. (2) It is difficult to set the route interval and the center of the joint weld. (3) The strength of concrete deteriorates due to heat during welding.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and can be used for construction of a structure such as a water storage tank, and does not require a long time for construction. The purpose of the present invention is to provide a composite version composite segment in which deterioration of concrete is not a problem.

[0008]

According to the present invention, there is provided a composite plate type structural member comprising two rectangular steel plates arranged in parallel by using a square steel pipe, an H-shaped steel, a T-shaped steel or a channel steel. L
A joint member formed in a U-shape, and a composite plate-type structural member formed in a substantially box shape by connecting with a partition plate disposed at a position facing one side of the joint member, wherein two of the L-shaped joint members are provided. The inner part of the side is sandwiched between the two rectangular steel plates, and is disposed so as to be parallel to each of two adjacent sides of the rectangular steel plate. The outer portion projects outside the two rectangular steel plates,
A portion of the partition plate opposite to a side facing one side of the L-shaped joint member and a portion opposite to a side where the partition plate is connected to another side of the L-shaped joint member are A space is formed in which one side of the joint member of another composite plate type structural member fits between the two rectangular steel plates.

In the case of constructing a structure such as a water storage tank by combining a plurality of composite plate type structural members according to the present invention,
The joint member formed in an L-shape is used as another synthetic plate type structural member 2.
The connection can be made easily because the connection can be made by being fitted between two steel plates.

[0010] In the case where adjacent synthetic plate type structural members are joined by welding, an accurate route interval of a welded portion can be ensured by the connecting member, and centering can be easily performed.

Further, the composite version composite segment according to the present invention is a composite version type structural member in which the space formed by the two steel plates, the joint member and the partition plate is filled with concrete.

Since this is a composite segment composed of steel and concrete, when used for construction of a structure such as a water storage tank, the waterproofness and the earthquake resistance are increased, and the strength is also improved.

Further, when constructing a structure by combining a plurality of composite plate-type composite segments, the position where the steel plates of adjacent composite segments are joined by welding is apart from the position where concrete is filled, so that the heat of welding is reduced. As a result, the concrete does not deteriorate.

Naturally, the composite version synthetic segment can be connected and welded in the same manner as the composite version structural member described above, so that a structure such as a water storage tank can be efficiently constructed. In addition to being able to improve the waterproofness and seismic resistance of the structure due to its structure, it is also possible to improve the strength,
The wall thickness of the structure can be reduced, and when a water storage tank is constructed in a site having the same area, a water storage tank having a large water storage capacity can be manufactured. In addition, when welding a steel plate, since welding is performed at a joint portion that is apart from a portion filled with concrete, the concrete does not deteriorate due to welding heat, and the durability of the structure is improved.

In addition, an H-section steel, an angle steel, or a channel steel may be used for the joint member of the synthetic version composite segment of the present invention, in addition to the square steel pipe.

[0035]
