BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an installation device for a roof panel material of a PC tank, and more particularly, to an installation device of a roof panel material when a roof portion of a PC tank is panelized and arranged.

[0002]

2. Description of the Related Art For the construction of a PC tank, a bottom slab concrete is constructed, a formwork is assembled on the bottom slab, and concrete is cast in place to construct a side wall. After that, a cast-in-place method of constructing a roof part by shoring a concrete structure by installing a shoring or a roof formwork in the side wall was often adopted. However, the above-described construction method requires a lot of formwork and support work when placing concrete on the side wall and the roof, and the construction cost is high. For this reason, in recent years, a method in which the side wall portion and the roof portion are made into precast panels and manufactured on the ground has been widely used.

[0003] In the precast panel method, the side wall and the roof are divided into a plurality of panel materials and manufactured. In the construction of the wall panel material, the panel material is erected one by one with a small space between the panels, and the side wall is produced by placing the concrete between the panels. In the construction of the roof panel material, supports are laid annularly at both ends of the roof panel material to be erected, and the roof panel materials are arranged one by one at intervals. If the PC tank diameter is large, a plurality of rows of panels are arranged in the radial direction. For the connection between the panels, after a formwork is erected on the lower part, a filling concrete is cast and integrated.

[0004]

The conventional technique of paneling the side wall and the roof as described above eliminates the need for many molds and supports during the manufacture of the PC tank, making it very economical. In particular, in the side wall portion, many forms and form supporting materials required on both sides of the side wall can be omitted.

[0005] However, in the roof portion, a support material for supporting the formwork is no longer necessary. However, as shown in FIG. 5, two supports are formed in a ring shape to support a row of panel materials. It is necessary to install many supporting columns, receiving stands, adjustment jacks, etc., which are support materials, and much time is required for the support work. Usually, the length of the roof panel material is set to about 4 to 6M in consideration of the bending stress at the time of erection. If the diameter of the PC tank increases, the panel material becomes a plurality of rows and the time required for the support work is further increased. .

[0006] Therefore, in order to solve the above-mentioned problems, the present invention provides a roof panel erection apparatus capable of efficiently constructing a PC tank with less support materials.

[0007]

That is, the present invention provides a PC tank previously fixed by a mounting bracket protruding from a panel end surface by a fixed dimension along the upper surface of a roof panel material, and a binding material for fixing the bracket on the roof panel. This is an installation device for roof panel materials.

[0008] As a mounting bracket of the mounting device, a steel or the like having a strength capable of supporting a roof panel is used, and has a length protruding from a panel end face by a certain dimension. The mounting bracket is fixed to the roof panel with a binding material on the panel.
Although the steel material has been exemplified as the construction metal fitting, a high-strength plastic material or the like developed in recent years may be used.
Bolts, nuts, and the like are used as binding materials, and are fixed through holes provided in the roof panel portion.

[0009]

The roof panel material in the first row is erected on a pedestal on the support material installed at the front end and on a roof ring manufactured on the side wall. When the erection of the first row is completed, the second row of roof panel materials to which the erection device is fixed is installed at the rear end of the roof panel material. The front part of the second-row roof panel is supported by a supporting material, and the rear part is supported on the front upper surface of the first-row roof panel material by a mounting bracket. In this way, in the installation of two rows of panel materials, the number of support materials can be reduced by one, and this becomes more remarkable as the number of roof panel arrangements increases.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a sectional view showing one embodiment of a roof panel erection device of the present invention. In this embodiment, a dome panel in the case where the arrangement of the roof panel members is two rows will be described as an example. When the construction of the side wall 7 is completed, the roof ring 8 is constructed on the upper part of the side wall 9. And the first row of roof panel materials 4
At the front portion of the roof panel material 4 corresponding to the length of the support panel 10, the support pillar 10, the adjustment jack 11, and the support material of the receiving stand 12 are assembled. When the installation of the support material is completed, the roof panel materials 4 in the first row are lifted one by one, and are supported by the roof ring 8 and the support 12 of the support material. The adjustment of the height of the roof is performed by the adjustment jack 11. When the first row of the roof panel members 4 is arranged on the circumference in this way, the rear of the second row of the roof panel members 5 is then arranged along the upper surface of the roof panel member 5. An erection device 1 in which an erection fitting 2 is fixed with a binding material 3 so as to protrude from an end face is provided.

When the erection apparatus 1 is completed, the roof panel members 5 in the second row are lifted one by one. The front part of the second row of roof panel members 5 is supported by a pedestal 12 of support material installed in accordance with the length of the second row of roof panel members 5. At the rear of the panel member 5, a mounting bracket 5 protruding from the end surface of the panel member 5 is supported on the upper surface of the front surface of the roof panel 4 in the first row. For this reason, the support material at the rear of the roof panel 5 in the second row becomes unnecessary.

When the arrangement of the roof panel members 5 in the second row is completed, a bottom formwork is installed in a gap between the panel members, and a filling concrete 6 is cast and an integrated roof member is obtained.

In this embodiment, the case where the arrangement of the roof panel materials is two rows is disclosed. However, if the diameter of the PC tank is increased and the arrangement of the roof panel materials becomes three rows, the erection apparatus becomes the second arrangement.
Equipped in rows and three rows, two supporting materials can be omitted.
As described above, the more the arrangement of the roof panel materials, the more the support material can be omitted.

FIG. 2 is a plan view for explaining how the roof panel members are erected. In the rear part of the roof panel material 5 in the second row,
Two mounting brackets of the mounting device 1 are installed in a state protruding from the rear end face of the panel 5 by a certain dimension. The mounting bracket 2 is used by being fixed so that two angle steels face each other.

In this embodiment, the number of the mounting brackets 2 is two.
Although it was disclosed in several places, it is necessary to consider the quantity according to the weight of the roof panel to be erected. In addition, although the angle steel is illustrated as the erection fitting 2, another steel material, a plastic material, or the like can be used.

FIG. 3 is a sectional view for explaining the details of the erection device 1. The erection fitting 2 is fixed to the second-row roof panel 5 with a binding material 3. The rear end of the erection fitting 2 is supported on the upper surface of the first row of roof panels 4 and matches the slope of the first row of roof panel materials 4. The connection part between each roof panel material, after fastening the roof reinforcing bar 13 protruding from each panel material by a certain dimension, fixing the bottom formwork 14 with the hanging metal fittings 15,
The concrete 6 is cast and integrated.

In the present embodiment, the binding material 3 is a bolt,
Although a fixing method using a nut is illustrated, a fixing method or a bonding method, which is a conventional technique, can be employed.

FIG. 4 is a plan view for explaining the details of the erection device 1. To disperse the erection metal fittings 2, after placing and hardening the filling concrete 6, prestress is introduced into the roof ring 8, and then the bolts and nuts as the binding material 3 are removed.
The erection bracket 2 is removed.

In this embodiment, the dome panel material has been described as the roof panel material. However, the present erection device 1 can also be used for a flat roof panel material.

[0020]

[Effects of the Invention] Normally, the roof of a PC tank constructed of several rows of roof panel materials required support materials at both ends of the roof panel material in the prior art. From the roof panel material of the eyes, it became possible to reduce the supporting material one by one, and the construction speed and economy were improved. This becomes more effective as the PC tank diameter increases and the panel arrangement increases.
