Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to construction methods for various plant buildings, including a pair of steel plates arranged in parallel, a connecting member that connects the steel plates to each other, and a connecting member that connects the steel plates to each other on each floor. a wall unit comprising a connecting member protruding outward from a steel plate and necessary equipment attached to the steel plate;
A floor unit consisting of a pair of parallel steel plates, a connecting member that interconnects the steel plates, a connecting member that projects the connecting member outward from the steel plates, and necessary equipment attached to the steel plates is prepared in advance. The wall unit is erected on the foundation, the wall units are connected to each other, the floor unit is temporarily supported on the wall unit, the connecting members of both units are joined together, and then The feature is that concrete is later poured into the joint and each of the units, and its purpose is to:
The object of the present invention is to provide an improved construction method for a plant building that is simplified in construction, has high structural reliability, and can significantly reduce construction period and construction cost.

In the present invention, as described above, a wall unit is constructed on a foundation by connecting a pair of parallel steel plates with a connecting member, and protruding the connecting member from the steel plate for each floor. In addition to connecting a pair of parallel steel plates with a connecting member,
A floor unit in which a portion of the connecting member protruding from the end of the steel plate is used as a connecting member is suspended in a space surrounded by a wall unit, and the end of the floor unit is temporarily supported by the temporary receiving portion. By connecting the connecting members of the wall unit and the floor unit to integrate both units, it is possible to connect the two units with ease and strength.

At this time, the pair of steel plates arranged parallel to each other in the wall unit and the floor unit are connected by a connecting member, so that a strong unit is constructed, and the protruding end of the connecting member from the steel plate is Since the two units are constructed as connecting members, the two units are rigidly connected through the joints of the respective connecting members, and concrete is poured between the pair of steel plates and at the joints in each unit. Therefore, the structure of the plant building is easy to construct and has high structural reliability.

Moreover, the wall unit is composed of wall slabs for multiple floors, and the floor unit is erected, temporarily supported, and joined for each floor in the same unit, so construction efficiency is further improved. According to the present invention, the construction period is significantly reduced and the construction cost is significantly reduced.

In addition, since the required equipment is pre-installed on the steel plates of each unit, most of the building frame work and on-site mechanical work is done at the factory, which greatly reduces on-site processes and man-hours, and improves construction accuracy. The present invention has many advantages, such as improved performance.

The present invention will be described below with reference to the illustrated embodiments.

A is a wall unit, and in the example shown, it is on the first floor (1F).
It constitutes the wall panels of the second floor (2F) and the third floor (3F), and
A pair of vertical steel plates 1 and 1' are placed opposite each other with a gap between them, and are connected by a web member 2 constituting the above-mentioned connecting member, and a large number of shear connectors 3 are installed on the steel plates 1 and 1'. ing.

At each floor part of the steel plate 1, a vertical member 4a extending from the web material 2 or integrally joined to the web material 2 is made to protrude from the steel plate 1, and the base of each vertical member 4a is attached to the steel plate 1. It is clamped by a pair of upper and lower horizontal members 4b and 4c that are welded together. Note that each of the members 4a, 4b, and 4c constitutes the above-mentioned connecting member 4. Further below, a floor unit temporary support portion 5 made of H steel is provided to protrude from the steel plate 1.

Further, a piping sleeve 6 and a box-shaped metal fitting 7 for forming a through hole for inserting wiring, etc. are attached to the vertical steel plate 1 when the wall unit is manufactured at a factory. (See Fig. 1) B is a floor unit, in which the end of the web material 9 constituting the above-mentioned connecting member that connects a pair of upper and lower horizontal steel plates 8, 8' arranged at a distance from each other is It projects outward from the steel plates 8, 8', and the projecting portion constitutes a connecting member. The lower horizontal steel plate 8' protrudes outward from the upper horizontal steel plate 8 so as to constitute a lower formwork for pouring concrete at the joint with the wall unit.

On the upper horizontal steel plate 8 are a tank 23, a heat exchanger 10, a pump 11, piping 12, a drain pipe 13,
Conventional machine side equipment such as sleeves and box outs 14 and partition walls 15 of only one level are installed when the floor unit is manufactured at the factory. In the figure, reference numeral 16 denotes a temporary support beam attached to the lower surface of the lower horizontal steel plate 8'.
(See Figure 2) The wall unit A is built on a reinforced concrete foundation C at a predetermined position, and the reinforcing bars 17 anchored to each of the steel plates 1 and 1' in the wall unit A are connected to the reinforcing bars of the foundation C. 18 through a reinforcing bar coupler 19, and the foundation C and wall unit A are integrated with the foundation concrete. Note that 20 in the figure is a rib material that reinforces the reinforcing bar coupler 19. (See Figure 3) Each wall unit A is thus installed in a predetermined position, and each wall unit A is joined by welding or other appropriate means (see Figure 4). floor unit B in the space
By suspending the temporary support beam 16 of the same floor unit B on the temporary support part 5 of the wall unit A, the floor unit B is temporarily supported on the same wall unit A, and the same floor unit B is temporarily supported. Unit B web material 9 and wall unit A
and the vertical member 4a of the connecting member 4, a splint 21 is attached across the web material 9 and the vertical member 4a, and they are joined with bolts 22. (6th
(See figure) Next, concrete is poured at the joint between both units A and B and inside each unit A and B.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
