JP7191284B2 - Pillar member and assembly booth - Google Patents

Description

The present invention relates to a collapsible booth installed in a partitioned area, for example, in an exhibition hall or the like, and a column member constituting the collapsible booth.

In an exhibition hall such as the Tokyo International Exhibition Center, each exhibitor is provided with a space, and the exhibitor builds a booth in the given space section to advertise and explain their own products. This type of exhibition is generally short-term, lasting only a few days, and simple assembly booths are used to facilitate installation and removal.
This type of knockdown booth has multiple columns (pillar members) and multiple beams that span between the columns. Generally, after forming a box-shaped frame, wall panels and floors are added. It is designed to

A height of about 2 m is required to block the view with the adjacent section. For this reason, it is difficult for one person to hold and support the pillar and assemble it while connecting other members, and it has been necessary to assemble a simple scaffold or increase the number of workers.
In order to allow one person to hold and assemble the pillars, it is necessary to make the pillars thinner, complicate the framework structure, and provide many screwed parts, as in the assembly type booth system described in Patent Document 1. .

JP-A-2003-82797

However, in the booth configuration described in Patent Document 1, the number of parts is large, and the number of man-hours required for screwing and fitting between members is very large, requiring time and labor for assembly.

In order to deal with this problem, the applicant of the present application has disclosed in Japanese Patent Application No. 2017-104107 that the number of parts is small and the configuration is simple, but the necessary strength can be secured, and even one person can assemble it in a short time. We proposed an assembly type booth that can reduce the cost of parts by using .
This assembly type booth has a column member configured by bundling, for example, four square timbers with spacers interposed therebetween in a state in which gaps are formed between the square timbers. When the lower end of the column member is fitted to the intersection of two floor materials arranged so that their ends intersect the floor surface in an orthogonal state and overlap vertically, the two floor materials are joined together. While being constrained in a perpendicular state, the column member is held in a self-supporting state by being supported by the two floor materials. Therefore, it is not necessary for the operator to hold the column member after the column member has been made self-supporting.
Four pieces of flooring are arranged so as to form a square with the ends perpendicular to each other, and after fitting and self-sustaining work of the above-mentioned column members are performed at each corner, a beam is fitted between the upper ends of each column member. Therefore, the frame structure of the booth can be temporarily constructed by one person. After the provisional construction, the framework of the booth is constructed by final tightening with fastening members such as bolts.

As mentioned above, the pillar member, which consists of a plurality of square timbers bundled together, has a length of about 2m, so although it can be carried by one person due to its weight, the length reduces the handling and portability. I can't deny that I do.
For example, when constructing a tea room or the like indoors, long pillar members are not easy to transport and handle. In addition, transportation is limited to trucks and other specialized vehicles, and large containers are required for export.

A temporary support structure for columns and an assembly booth according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a frame structure of a knockdown booth (hereinafter simply referred to as "booth") 1 in a state where column members are temporarily held according to the present embodiment. This frame structure includes four floor members 3A to 3D placed on the floor so as to partition, for example, a square area, four vertically erected column members 5A to 5D, and each column member. It has four beams 7A to 7D connecting the upper ends of 5A to 5D. Both the width W and the height H of the booth in this example are 200 cm, and one side S of the column member 5 is 9 cm. As will be described later, in the present embodiment, all the elements are composed of 3-cm-square wood-based square timbers (rod-shaped members), that is, square timbers having a square cross-sectional shape. The above dimensions are an example and are not limited to these.

As shown in FIG. 2, the four floor materials 3A to 3D are arranged such that the floor materials 3B and 3D are placed directly parallel to the floor surface, and the floor materials 3A and 3C are placed on the floor materials 3B and 3D. are placed parallel to each other in a direction orthogonal to That is, the floor materials 3A and 3C are arranged on the floor materials 3B and 3D so that the ends of the floor materials 3A and 3D overlap vertically.

Each of the column members 5A to 5D has a divided structure in which it is divided into two in the vertical direction (axial direction), and is connected by a joint member (intermediate member) 6 at the central portion in the vertical direction. Details of the connection configuration will be described later.

The column member 5A has a fitting shape that constrains the orthogonal state of the flooring materials 3A and 3D by fitting the lower end portion to the intersection of the flooring materials 3A and 3D from above. As shown in FIG. 3, it is held in an independent state by being supported by floor materials 3A and 3D.
In other words, the post-fitting column member 5A does not require fastening operations such as screwing. It is held in a self-supporting state. Other column members 5B to 5D also have a fitting configuration similar to that of column member 5A.

Therefore, the operator can erect the remaining three column members 5B to 5D in the same manner, and after erecting the column members 5A to 5D, the assembled beams 7A to 7D are placed at the upper ends of the column members 5A to 5D. By fitting it into the frame structure of the booth 1, one person can provisionally construct it. After the provisional construction, final tightening (integration) is performed using fastening members such as bolts. A specific configuration of final tightening will be described later.

Each of the column members 5A to 5D has a configuration in which a plurality of rectangular timbers are integrally bundled and fixed via spacers so that gaps exist between rod-shaped members around the axis.
Specifically, four timber-based square timbers 9 of 3 cm square each are fixed, and spacers 11a, 11b, etc. made of the same square timber are fixed between the square timbers 9 so that the projected shape of the entire upper and lower ends becomes a square shape. configured as one. That is, there is a gap corresponding to one square timber between the square timbers 9 and at the center surrounded by the four square timbers 9 .
As shown in FIG. 4, at the lower end of the column member 5A, a spacer 11a whose lower end abuts against the upper flooring 3A is fixed in the facing gap between the square timbers 9A and 9D and between the square timbers 9B and 9C. A spacer 11b whose lower end abuts against the lower floor material 3D is fixed in the facing gap between the square timbers 9A and 9B, and between the square timbers 9C and 9D.

The spacers 11a are fixed by long bolts (not shown) horizontally penetrating the three square timbers 9A, 11a and 9D, and 3 square timbers 9B, 9B, 11a and 9C. Fastened with a nut. The spacers 11b are fixed by long bolts (not shown) that horizontally penetrate the three square timbers of the square timber 9A, the spacer 11b, and the square timber 9B, and the three square timbers of the square timber 9C, the spacer 11b, and the square timber 9D at two upper and lower positions. Fastened with a nut.

The spacers 11a and 11b have the same length, but the spacer 11b is spaced between the floor surface and the square timber so that a first fitting recess 12 for accommodating two square timbers can be formed between the spacer 11a and the floor surface. It is fixed so as to form a second fitting recess 14 for accommodating one piece. The same applies to the other column members 5B-5D.

The principle by which the column member 5A is held in an upright state simply by fitting it to the intersection of the two floor materials 3A and 3D will be described below.

FIG. 5 is a cross-sectional view taken along line X1-X1 in FIG. 3 at the lower end of the column member 5A. As shown in FIG. 5A, when the column member 5A is about to fall inward (d1 direction; see FIG. 3), the lower end of the spacer 11a on the side of the rectangular timber 9C presses the floor 3A and The lower end of 9C presses the floor material 3D to impart a clockwise rotational moment to the floor material 3A.
However, since the other end side of the floor material 3A is supported by the floor material 3B, a reaction force RF is generated, and as a result, the inward collapse of the column member 5A is suppressed.

As shown in FIG. 5(b), when the column member 5A tries to fall outward (direction d2; see FIG. 3), the lower end of the spacer 11a on the square member 9D side presses the floor member 3A, and , the lower ends of the rectangular timbers 9D press the flooring material 3D to impart a counterclockwise rotational moment to the flooring material 3A.
However, since the moment GF due to the weight of the floor material 3A acts in the clockwise direction, the collapse of the column member 5A to the outside is suppressed.

FIG. 6 is a cross-sectional view taken along line X2-X2 in FIG. 3 at the lower end of the column member 5A. As shown in FIG. 6A, when the column member 5A tries to fall outward (d3 direction; see FIG. 3), the lower end of the spacer 11b on the side of the square timber 9B presses the floor 3D and The spacer 11b on the side of 9C presses the floor material 3A to impart a clockwise rotational moment to the floor material 3A.
However, the weight of the other end of the floor material 3A causes a reaction force RF, and as a result, the column member 5A is restrained from collapsing outward.

As shown in FIG. 6B, when the column member 5A is about to fall inward (d4 direction; see FIG. 3), the lower end of the spacer 11b on the side of the rectangular timber 9C presses the floor 3D and The spacer 11b on the side of 9B presses the floor material 3A and gives the floor material 3A a rotational moment in the counterclockwise direction.
However, a reaction force RF is generated by the weight of the other end of the floor material 3A, and as a result, the collapse of the column member 5A inward is suppressed.
The other column members 5B to 5D also have the same collapse prevention function as described above, and the column member 5 can be assembled by one person.

Based on FIGS. 7 to 11, the column member 5A will be described as a representative of the connection structure of the column member 5. FIG.
