Abstract

An internal reinforcement structure for a wall-standing rectangular steel water tank is provided which is low in construction cost and convenient for maintenance and inspection.
In the steel water tank having a rectangular horizontal cross section, a conventional horizontal bar that connects both ends to opposite pressure receiving side walls 1a, 1b is not installed, but instead, the purpose is to reinforce the pressure receiving side walls 1a, 1b. An internal reinforcement structure of a wall-standing rectangular steel water tank in which a vertical assembly truss beam 4 composed of a horizontal bar 4a, a vertical bar 4b and an inclined bar 4c is installed was devised.

Description

The present invention relates to an internal reinforcing structure of a rectangular steel water tank that is low in construction cost and convenient for maintenance and inspection.

  As shown in FIG. 3, conventionally, a large-capacity rectangular steel water tank 1 such as a distribution reservoir or a water receiving tank has a thin pressure receiving side wall 1a, 1b and cannot independently resist a horizontal hydraulic pressure load. Conventionally, an internal reinforcing structure in which horizontal reinforcing bars 2 that connect both ends to opposing pressure-receiving side walls is installed. In this case, the opposing pressure-receiving side walls 1a and 1b of the water tank 1 are integrated and stabilized by receiving a hydraulic load having the same size but the opposite direction.

However, when the capacity of the water tank is increased, the above-described conventional technology has the following disadvantages.

  The number of the horizontal reinforcing bars 2 increases as the depth of the water tank body 1 increases, and the length of the horizontal reinforcing bars 2 increases as the width of the water tank body 1 increases. In addition, a vertical bar 3 for supporting the horizontal reinforcing bar 2 As a result, it is necessary not only to increase the material cost and construction cost of the aquarium, but also because the horizontal reinforcement bar 2 and the vertical bar 3 are densely packed in the aquarium 1, for maintenance and inspection of the aquarium. The workability of becomes worse.

  Large-capacity rectangular steel tanks such as reservoirs, receiving tanks, etc. are excellent in terms of site shape, and in addition, many merits such as earthquake resistance, aesthetics, hygiene, free maintenance are evaluated and accelerated as public facilities While the results are growing, safety and cost reduction are required. Therefore, it is an urgent task to devise a safer and more rational internal reinforcement structure to reduce the construction cost.

In order to solve the above-mentioned problem, as shown in FIGS. 1 and 2, the device according to the first aspect of the present invention includes a pressure-receiving side wall inside the opposing pressure-receiving side walls 1a and 1b in a steel water tank having a rectangular horizontal cross section. The gist of the present invention is to use an internal reinforcing structure characterized in that a vertical assembly truss beam 4 composed of a horizontal bar 4a, a vertical bar 4b, and an inclined bar 4c is installed for the purpose of reinforcing 1a and 1b.

  As shown in FIG. 1, the device described in claim 2 is a vertical bar 8a for supporting a load / snow load received by the ceiling plate 1c immediately below the ceiling plate 1c, as shown in FIG. The gist of the invention is to use an internal reinforcing structure in which a horizontal assembly truss beam 8 composed of a horizontal bar 8b and an inclined bar 8c is installed.

  As shown in FIG. 2, the invention described in claim 3 includes vertical bars 5 and 7 called column members for supporting the load / snow load received by the ceiling plate 1 c, as shown in FIG. 2. The gist is to use an internal reinforcing structure characterized in that a horizontal bar 6 called a beam that intersects with these 5 and 7 is installed.

  The greatest feature of the present invention is that, unlike the conventional internal structure system shown in FIG. 3, there is no horizontal reinforcing bar 2 in the aquarium body 1, that is, the connection of the pressure-receiving side walls 1a, 1b facing each other. There is no so-called wall self-supporting rectangular steel tank internal reinforcement structure. This internal reinforcement structure greatly reduces the total weight of members required for construction of a water tank, particularly a large-capacity water tank, and does not require welding work at the intersection of the conventional horizontal bar 2 and vertical bar 3 shown in FIG. Therefore, it is possible to reduce the cost of water tank construction in terms of both material costs and construction costs.

  Also, the dense arrangement of the conventional horizontal bar 2 and vertical bar 3 shown in FIG. 3 is eliminated, and there is a sense of openness inside the aquarium body 1, which is expected to greatly improve workability for maintenance and inspection of the aquarium. can do.

FIG. 1 shows the best mode for carrying out the invention.

  As shown in FIG. 1, a vertical assembly truss beam 4 that reinforces the pressure-receiving side walls 1a and 1b is installed on the opposite pressure-receiving side walls 1a and 1b of the water tank body 1, so that the pressure-receiving side wall 1a on one side can resist the hydraulic load. The members 4a, 4b, 4c of the vertical assembly truss beam 4 are designed.

  A horizontal assembly truss beam 8 that reinforces the ceiling plate 1c is installed directly below the ceiling plate 1c, and the members 8a, 8b, and 8c of the horizontal assembly truss beam 8 are designed so that they can resist ceiling loading and snow load.

  In the water tank having the above internal reinforcement structure, when water enters, the vertical assembly truss beam resists the hydraulic load and the horizontal assembly truss beam resists the ceiling loading / snow load, ensuring the safety of the tank. .

  Example 1 of the present invention is the best mode for carrying out the present invention, as shown in FIG.

  In the second embodiment of the present invention, as shown in FIG. 2, instead of the horizontal assembly truss 8 of the first embodiment, vertical bars 5 and 7 and a horizontal bar 6 intersecting these (5, 7) are installed. It is.

  Although the present invention has been described using the vertical plane of the two-dimensional water tank, the same internal reinforcement structure is also installed for the vertical plane perpendicular to the vertical plane described.
