Description

[Detailed description of the invention] This invention relates to an assembly frame for an aquarium, which is usually constructed by assembling H-shaped or U-shaped steel into a flat rectangular shape with the groove facing outward, and providing vertical and horizontal or diagonal crosspieces on the inside. ,
The main feature is that the welded flat frame is assembled by tightening bolts and nuts, and a drill insertion hole is provided in the upper flange coaxially with the foundation bolt hole so that it can be fixed to the foundation concrete on the spot. , pass a drill from directly above through the foundation bolt holes of the lower flange and drill into the hardened foundation concrete.
This suppresses the swinging of the drill during drilling, making it possible to insert and secure mechanical anchor bolts after drilling.

Water tanks installed in basements, rooftops, etc. of buildings are
Recently, the installation of large aquariums has become easier with the adoption of assembled aquariums in which resin panels are connected one after another. However, there has not been much progress in the installation work of fixing the assembled water tank onto the concrete foundation. As always, we bring the molded steel materials to the installation site, cut them to the required dimensions, weld them, and assemble the frame, and then drill the water tank mounting holes and foundation bolt holes in the front and back. Then, the pedestal is tightened and fixed using the foundation bolts that the concrete worker who made the foundation concrete placed on the installation surface, and the water tank is placed on top of it.

Even if the cutting and drilling of shaped steel materials are made in a factory,
There is no change in the fact that the frame is integrated by welding and is installed using foundation bolts erected by concrete workers.

On-site assembly by welding requires welders and welding equipment, inspection of its actual strength is troublesome, and there are problems with dimensional changes and twisting due to welding distortion. The most troubling problem was that the foundation bolts installed by the concrete contractor and the foundation bolt holes of the pedestal rarely matched exactly as they were.

This idea eliminates the need for welding when assembling the frame on-site.
Furthermore, by using the foundation concrete drilling drill insertion holes drilled in the pedestal to drill and secure the foundation bolts on the spot, and by fixing the pedestal to these ready-made foundation bolts, the above problem is completely resolved. That's what I did. Next, the configuration and implementation of this invention will be explained with reference to the drawings.

Figures 1 and 2 show an embodiment of this invention, in which the outer circumferential members assembled in a rectangular shape on three foundation concrete stands C, that is, the outer circumferential vertical members 1a, 1b, the outer circumferential cross members 2, and the inner circumferential members. The vertical bars 3a, 3b and the horizontal bars 4 are all factory-manufactured shaped steel straight members of specified dimensions. The joints where these parts are combined are all tightened with bolts and nuts via intermediary members 5a, 5b, and 5c of specified dimensions manufactured at a factory.

Exploded perspective views of the joints X, Y, and Z in FIG. 1 are shown in FIGS. 3, 4, and 5. The intermediary member 5a is a piece of angle iron with reinforcing trapezoidal plates 6 welded at both ends at the factory, and when the vertical members 1a and the horizontal members 1b are placed at right angles as shown in Figures 1 and 2, they are pre-drilled. The holes 7 are drilled at positions where the assembly holes 7 coincide with each other.

The intermediary member 5b in FIG. 4 is made by welding a vertical plate 9 to a connecting plate 8 in a T-shape.
A and 1b are connected in a straight line, and assembly holes 7 are formed in each of them so that the four ends of the horizontal beams can be attached to the vertical plate 9 at the same time for three-way joining.

In the intermediary member 5c of FIG. 5, the vertical plate 9 of the above-mentioned intermediary member 5b is thinner and has become a vertical plate 9' extending as long as the depth of the mold groove. As shown in FIG. 5, the joint ends of the vertical bars 3a and 3b are sandwiched from the front and back by both intermediary members 5b and 5c and bolted, and the respective vertical plates 9,
The four ends of the horizontal beams are bolted to 9' to achieve a four-way connection.

It goes without saying that the shapes of the intermediary members 5a, 5b, and 5c of the joints can be varied in various ways according to the well-known techniques of mechanism designers. In short, any intermediate member is sufficient as long as it is used to join the end portions of the shaped steel in a straight or right-angled manner. All of these are manufactured in a factory, but they are brought to the site as single items and used as shown in Figures 3 to 5, as well as in Figures 6 to 5.
As shown in Fig. 8, the molded steel members may be welded and fixed at required positions in advance and brought to the site all at once. 6th
As can be clearly seen in FIG. 8, the intermediary members 5d and 5e in FIGS. 8 to 8 are a flat plate 5d welded into the groove of the molded steel and projecting outward, and a plate 5e bent at right angles. These intermediary members are outer peripheral members 1a, 1b, 2, crosspieces 3a, 3.
The shape is such that the upper surfaces of the upper flanges b and 4 can be aligned and joined on the same plane.

The outer peripheral member type steels 1a, 1b, 2 have bolt holes 7 for frame assembly, foundation bolt receiving holes 7a, foundation concrete drilling drill insertion holes 7b, and water tank mounting holes 7.
c is left open when manufactured at the factory.

In the case of an assembled aquarium stand, since the resin unit panels are attached one after another to the upper surface of the stand, a large number of aquarium attachment holes 7c are required in the upper flanges of the outer peripheral member mold steels 1a, 1b, 2, as shown in FIG. Further, foundation bolt holes 7a are required at required positions on the lower flange. These are the same as before. However, all of the foundation bolt holes 7a are for mechanical anchor bolts, and are located away from directly below the water tank attachment hole 7c of the upper flange.

This invention differs greatly from the conventional one in that a foundation concrete drilling drill insertion hole 7b is provided in the upper flange coaxially with the foundation bolt hole 7a in the lower flange. Of course, since the drill is used to drill the mounting hole for the mechanical anchor bolt, a drill insertion hole of an appropriate size is coaxially drilled.

As shown enlarged in FIG. 9, the outer peripheral members 1a, 1
Both b and 2 have drill insertion holes 7 in the upper flange directly above the foundation bolt holes 7a in the lower flange.
b is left open. Outer peripheral members 1a, 1b,
2 is assembled and placed in the correct position on the foundation concrete C, insert the tip of the drill into the foundation bolt hole 7a through the drill insertion hole 7b shown in FIG. 9, and stand it on the concrete surface. Of course, the drill was attached to a portable drilling machine, and in the experiment it was possible to drill one foundation bolt hole 11 within 30 to 60 seconds. A mechanical anchor bolt 10 is inserted into the hole 11, and the lower part of the bolt 10 is opened as shown in FIG. 9 by tightening a screw or by hitting the bolt. Then, the lower flange of the molded steel is fixed to the C surface of the foundation concrete using washers 12 and nuts 13.

FIG. 10 shows the state in which the lower part of the water tank T is attached to the frame fixed on the foundation concrete C in this manner. Directly above the anchor bolt 10, the drill insertion hole 7b remains empty as shown in FIG.

Although one embodiment has been described above, the steel members and intermediate members of the prefabricated frame of this invention can be varied in many ways using the techniques known to steelworkers. Furthermore, the layout and dimensions of the assembly holes, foundation bolt holes, drill insertion holes, and water tank mounting holes should be determined by the designer as appropriate according to the implementation conditions.

This idea changed the aquarium stand, which had traditionally been produced as a single item and required on-site welding, to an assembled product of mass-produced shaped steel straight members of specified dimensions and intermediary members, making it easy for even unskilled workers to create a stand with excellent dimensional accuracy. , can be assembled efficiently. Since the drill insertion hole is drilled in the upper flange directly above the lower flange where the foundation bolt hole is located, it can be inserted into the foundation bolt hole of the lower flange without being obstructed by the upper flange of the frame type steel assembled on the foundation concrete. Mechanical anchor bolt mounting holes can be immediately drilled using a drill. If the drill insertion hole in the upper flange is used as a jig hole for supporting and guiding the drill, even an unskilled person can easily and accurately drill the hole. This completely solved the problem of discrepancies between the foundation bolts and the mounting holes, which had been a problem in the past. It is well known that mechanical anchor bolts themselves are superior to recessed anchor bolts.

In addition, the drill insertion hole makes it possible to pass a stopper rod that fits the pin head and hit the head with a hammer when driving the opening pin head of the impact opening type mechanical anchor bolt. This idea is conventionally called a prefabricated pedestal, but it is not just a prefabricated type; for example, in a basement with a narrow entrance, the aquarium pedestal can be assembled and installed using mechanical anchor bolts at a location where there are no anchor bolts in the old concrete foundation. We have been able to provide a new type of mount that can be called an assembly and installation type.
