Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to an improvement in the construction method of a building having a large space such as a gymnasium.

The structures of this type of building generally include a reinforced cosiclete structure, a steel frame structure, a suspension structure, and an air expansion structure. These structures are
! Rumor has it that each has its own unique characteristics, and two have been selected depending on the purpose of the building.

In particular, steel structures use steel frames for the main parts of buildings, which correspond to the pillars and beams, so in order to make a large open movement with a steel structure, the columns must be high and the beams and girders must be very wide. Therefore, it is common practice to join the individual components with bolts, etc., which requires large-scale temporary construction such as scaffolding, and involves the dangerous work of directly joining the members. Additionally, a sky-moving lifting machine was required to erect columns and lift beams and girders.

In order to eliminate such risks, large-scale temporary construction, and the use of OSE's lifting equipment, or to shorten the construction period, tit root members were assembled on the ground and pre-erected pillar S materials were used. A construction method has been developed in which the assembled Otori root members are lifted up, but this method inevitably requires columns erected vertically, and this construction method cannot be applied to J1m structures with @-faces. Is there a need to build a separate rental department?

The present invention has been made in order to solve the problems in the conventional construction method.The S beam is divided into a plurality of units, which are connected on the ground by screw joints in advance, and both ends are connected. The present invention provides a method for constructing a building, characterized in that a beam member having a predetermined shape is formed by raising the central portion of a group of consecutive beam units by drawing them together using appropriate means.

Next, an embodiment of the present invention will be described with respect to a case where a semicylindrical 11a beam member having a semicircular spatial cross section is constructed.

The first WJ shows a schematic perspective view of a building constructed by the construction method of the present invention, in which (1) is a plurality of beam members for forming a semicircular space (2), which are placed on the ground at predetermined intervals. The beam members (1) are connected at predetermined intervals by connecting members (3) to create a skeleton, and the j1 root material (4) is attached on top of the beam members (1) to create a semicircular shape. It constitutes a building (5).

The beam member (υ) is a beam unit (6) having a trapezoidal elevation as shown in FIG.

The beam unit (also) has two FK low sap members (7) (7) arranged in parallel with each other at regular intervals in the direction of the beam member (1), and both ends thereof are connected with connecting members ( (b) Connected by (b), two fiffi sapwoods (8) and (3) are arranged in parallel downward through the direct timber (2), and both ends of the fiffi sapwood are connected by the connecting material o.
They are connected by acL1 to form a trapezoidal shape and have a truss structure.

(b) is the #1 material attached for reinforcement as necessary. 0so (foundation) is the ear member fixed to both ends of (7), and the hole 0fj ( (b) are bored, and (6) are ear members attached to both ends of the short and low sapwood (8) (8), respectively, and a bisque hole (b) (6) is bored therein.

In addition, the sides of the truss structure formed into a trapezoidal shape and the elongated sap material (
The angles lcL and tβ formed with 7) are both acute angles. Note that the elongated sapwood (7) and the g1 sapwood (8) do not necessarily have to be straight timbers, but may be curved timbers that match the cross-sectional shape of the building.

To form the beam member (1) using the beam unit (6) described above, first place a pedestal gQ on top of the cosiclete or rail (2) laid on the continuous site, as shown in No. 6 WJ.
[Multiple beam units (6) are placed in series through the
al) (6s)---(6n-s), (eH),
The holes t1i)tli in the opposing ear members fixed to both ends of the elongated sap material (7) of each of those beam units (6)
) and insert the biscuits (9) to connect them rotatably.

In this case, the connection state of the adjacent beam units (6) (6) is Lr = 2R - Otsu, 1, and β, and each beam unit (6)
) are arranged on a straight line. (However, r
is an included angle formed by the straight members (2) forming the side parts of the beam units (6) that touch each other).

In addition, in the figure, ear members are unnecessary at the outer ends of the elongated sap members (7) of the surface layer beam unit (61) and the rightmost beam unit (6fi). Outer ear part (18I) of the equipment sap material (8 bar 8) of the rightmost beam unit (6n)
(19n), the O-rad end of Java + (c) (b), whose both ends were identified on the rail (g), is 1m! Then, if you press horizontally in the opposite direction, the pressing force of one Java pepper (2) will be the same as the lug II (18t) N7i) of the beam unit (61).
Also, the pressing force from the other Java center wheel acts upwardly to the left through the ear part N9n) + tan) of the beam unit [6n), and the upward portion of these pressing forces By force, beam unit +61 ), (6s) and (6n),
(An-13 rises up and becomes the state shown in No. 48!J. Further, when pressing with =; Raise the beam holes of all the ear members (g) (6) of the beam unit (6) until they match, and insert and connect the four holes to form the beam member (1). Fix the beam units (6□) and (an) at both ends of the beam member (1) to the cosiclete foundation), and! ;Remove the guy + (goods) (2) and erect the beam member (1).

By sequentially performing the above series of operations, a plurality of beam members (1) are erected at predetermined intervals and connected with connecting members (3),
Attach the cliff IN @ (4) and close the opening end of the space (2) as appropriate to create the semi-cylindrical structure (5) shown in Figure 1.
The goal is to build

In this case, if the included angles lr formed by the side parts of the beam units (6) that are mutually S* are equal and their total is π, the identified end will be at right angles to the ground surface By making the angle , it is possible to construct a 11M object having a spatial cross-sectional shape of Ninroku.

In the above embodiment, the pressing force of (2) was applied to the beam units at both ends from opposite directions, but one beam unit is fixed and the pressing force of (2) is applied to the beam units at both ends. The beam unit may be pressed only by the inside of the beam, or the beam unit may be raised by pulling it with a wire or the like.In addition, in the above embodiment, the beam member (1) is erected and then the beam unit is raised. Although the connecting member (3) and the M1 root M(4) are connected, in the present invention, the connecting members are connected while the plurality of beam unit connecting bodies are placed on the ground in parallel at predetermined intervals. The beam member (1) may be constructed by simultaneously raising the entire structure after attaching the material (3) and the roof material (4).

Further, the present invention is not limited to semicylindrical constructions, but can also construct donut-shaped or dome-shaped buildings by devising the arrangement of the beam members (1).

As described above, the present invention includes a plurality of beams formed in the shape of four trapezoids, with the long side portions of one unit facing upward, and both ends thereof being rotatably connected to form a beam unit connected body. Both ends of the beam unit continuum are pulled together to raise the center part thereof, and both ends of the device sides of the beam unit are connected to each other to form a beam member, and both ends are fixed. Since this relates to a method of constructing a building that constitutes the skeleton of a building, it is possible to construct a beam that forms the skeleton of a building by simply applying a horizontal force to the connected body of beam units.
Since it can be erected, there is less work to be done at heights, which reduces dangerous work.Also, most parts can be installed on the ground, so it is not necessary to use large-scale temporary construction materials or large-scale lifting equipment. Moreover, by devising the arrangement of the beam members, the spatial cross-sectional shape of the Il relic constructed can be formed arbitrarily to obtain the desired space, so the dead space can be reduced. It has the following features.
