Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fixing structure for fixing the upper end of an inner support to a ceiling wall in an assembled water tank.

[Prior art and its problems]

Conventionally, this type of structure for fixing the upper end of the inner support column to the ceiling wall is disclosed in Japanese Utility Model Application Laid-Open No. 57-199596 (FIGS. 6 and 7).

In this prior art, a flange piece 102 is provided extending on the side edge of a cylindrical part 101 having the shape of a half of the outer periphery of the upper end of the inner support B, and a support piece 103 perpendicular to the flange piece 102 is further provided to form a pair of supports 100. , 100, and the cylindrical portions 101, 101 of the pair of supports 100, 100.
Hold the upper end of the inner support B with the support pieces 103, 103.
, the joining flange 1 hanging from the ceiling wall panel 1
A and 1a are fixed together using bolts and nuts 104 that connect them together.

By the way, if the pair of supports 100, 100 in this prior art are fixed to the joint flanges 1a, 1a in advance, it will obstruct the erection of the inner pillar B, so the cross-shaped joint formed between the ceiling wall panels 1... Part a
Due to handling restrictions, it cannot be fixed until after the inner support B has been erected under the .

However, while artificially transitioning the cylindrical inner column B from an inclined state to an upright state against the reaction force of the ceiling wall _A1 and the bottom wall, the axis (column center of the inner column) was changed into a cross shape. The work of locating it directly below the joint part a requires precision, which causes the problem of complicating the work of erecting the inner support, which must be improved.

[Technical issues]

The technical problem of the present invention is that in the mounting structure of the inner column in which the upper end of the inner column is held by a pair of supporting members,
The object of the present invention is to enable one of the supporting members to be used as a guide body for easily positioning the column core under the cross-shaped joint between the panels when the inner column is erected.

[Technical means] The technical means taken to achieve the above technical problem is to provide a pair of support members with end faces that extend along the joint flange corners of ceiling wall panels facing each other across the cross-shaped joint. It consists of a mounting piece that is separately fixed to each panel, and a curved clamping piece that hangs down from the mounting piece and comes into contact with the outer peripheral part of the inner column facing below the joint flange forming the cross-shaped joint. It was formed in one piece.

[Effect]

The effects of the technical means of the present invention are as follows.

Γ Fix the mounting piece of one support member to the ceiling wall panel by bringing the end face into contact with the joint flange corner of the ceiling wall panel facing each other across the cross-shaped joint in the ceiling wall. At this time, the curved clamping piece that is vertically installed on the mounting piece faces under one of the joining flanges that make up the cross-shaped joint, part of the outer periphery of the inner column that will be erected later. (To be exact, approximately 1/4 circumference), and by artificially erecting the inner column along this clamping piece, the inner column has its core directly below the cross-shaped joint. The self-supporting state is automatically maintained at the same position on the same axis.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

In the figure, A is a water tank, _B is an inner support, and C is a pair of supporting members.
The inner column B is vertically erected across the bottom wall _A2 by positioning the upper end and fixing this upper end with supporting members C hanging down at two locations facing the ceiling wall _A1 .

The inner column B is for supporting and holding the ceiling wall _A1 of the aquarium A, and is made of metal, synthetic resin, etc. and has an arbitrary outer diameter according to the purpose of use.
It is formed into a hollow pipe shape with a length equal to or slightly longer than the height between the lower end surface of the joint flange 1a on the peripheral edge of the ceiling wall panel 1 that assembles and forms _{A 1 and} the support surface 2 of the bottom wall A 2. .

Support members C and C connect the upper end of inner support B to the ceiling wall.
This is for attaching and fixing to the cross-shaped joint a of _A1 , and the mounting piece is made of hard resin, metal, etc.
Approximately L from c ₁ , c ₁ and clamping pieces c ₂ , c ₂ extending downward from the edges of the mounting pieces c ₁ , c ₁ .
It is integrally formed in the mold.

The mounting pieces c ₁ , c ₁ are formed into flat plate shapes having end faces along the joint flanges 1 a of the ceiling wall panels 1 facing each other across the cross-shaped joint a on the ceiling wall A ₁ .

The clamping piece _c2 is formed in a curved shape along the outer peripheral portion facing below the corner of the joint flange 1a forming the cross-shaped joint part a of the inner column B.

Note that 3 in the figure is a mounting hole formed in the mounting piece _c1 of the support member C.

It goes without saying that when the support member C is made of a metal material, its surface is coated with a resin material or the like to prevent rust.

Next, to explain the procedure for fixing the upper end of the inner column B using the supporting members C and C formed as above, first, the ceiling wall panels facing each other across the center of the cross-shaped joint a. 1 joint flange 1
Corner flat surface 1 by touching the end face to the a corner
By attaching the mounting piece c ₁ to b via the bolt 4, nut 5 and washer 6, one support member C
to be fixed. At that time, the clamping piece _c2 is suspended from the ceiling wall _A1 . After that, one side of the outer upper part of the inner support B is brought into contact with the curved inner surface of the holding piece _c2 , and the inner support B is vertically erected across the support surface 2 of the bottom wall _A2 as a guide. Next, join the joint flange 1 of the other ceiling wall panel 1 facing across the cross-shaped joint a.
Corner flat surface 1 by touching the end face to the a corner
b, fix the support member C by attaching _the mounting piece _c1 via the bolt 4, nut 5, and washer 6 with the curved inner surface of the clamping piece c2 in contact with the outer upper part of the inner column B. The upper end of the inner column B is immovably fixed to the cross-shaped joint a of the ceiling wall _A1 .

Further, the means for fixing the lower end of the inner column B to the bottom wall _A2 is arbitrarily set depending on the form of the bottom wall _A2 .

[Effect of idea]

Since the present invention is constructed as described above, it has the following advantages.

The clamping piece of one of the supporting members can be used as a guide surface for the inner column, which is installed directly below the cross-shaped joint between each panel of the ceiling wall with the column cores aligned coaxially. In addition to the act of artificially transitioning from a tilted state to a self-supporting state against the reaction force of Compared to the prior art, the inner struts are automatically aligned without the need for accurate positioning work, and the manual work from aligning the inner struts to fixing the upper end can be reduced and simplified. .

Thus, the intended purpose can be achieved.
