DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction method of a large span building according to the first and second aspects of the present invention is a method of constructing a large span roof having an outer peripheral portion having an arcuate outer peripheral surface within a plane of the roof. Constructed at approximately the same height as the roof in the included fixed work yard, advance by the traveling method by the length of the completed roof, and proceed with the building construction in a series, leaving the remaining center side part directly below the plane In the same way as the conventional construction method, it is built on the work stage at the original roof height (invention of claim 1), or it is built at the ground level immediately below and installed at the roof position by the vertical transportation method It is suitably implemented as a complex building construction method. In other words, the construction of the roof frame is divided into a plurality of parts, an outer peripheral part and a central part, and each of the construction steps is proceeded. This can greatly reduce the construction period. In addition, on the flat surface of the roof, there is no free space other than a work yard and no scaffolding, support, etc., and the construction of the lower frame of the building can be performed in parallel on the ground portion in that range. In addition, a tall tower crane or the like is erected in the work yard on the outer peripheral part because of the necessity of steel frame construction, etc. On the other hand, the work yard in the central part which is usually the highest part of the building is particularly tall. The cranes are useless for construction. Therefore, even when building in a place subject to height restrictions,
It is easy to overcome the limitation and the construction is not particularly affected by the height limitation.

The embodiment shown in the drawings will be described in more detail. FIG. 1 shows a main process chart of the construction method of a large span building according to the present invention. FIGS. 2 and 3 show an example of a large span building. In plan view, a large arc A and a small arc B are each a part of a circle (arc), and the two arcs A and B are joined together. An example of a planar shape having symmetry in two axial directions such as an approximate elliptical shape is shown.

As a construction plan (plan) of the building construction method according to the present invention, the roof frame of the building is formed by removing an outer peripheral portion including arc-shaped outer peripheral edges a and b as viewed in plan as shown in FIG.
A plurality of outer peripheral portions, each inner peripheral edge a 'and b' being divided into a fan shape forming a concentric circle with the outer peripheral edge, and
And a plurality of remaining center-side portions excluded from the outer peripheral portion. Incidentally, the center-side portions generated at two positions on the left and right in FIG. 2 are portions specified in a fan shape including the center P of a circle that is a small arc B (outer peripheral edge b, inner peripheral edge b ′). The other central part is the part that is finally left.

As long as the floor plan is performed by the above method, no matter what the plan shape of a large span building is, it is roughly divided into an arc portion and a straight line portion, and the radius of the arc portion is further increased. The construction can be easily performed by dividing into large and small. As an extreme example, for example, even in the case of an ellipse having no center in particular, or a planar shape including the outer periphery of a second-order or third-order curve, by sorting each inner periphery in a so-called parallel manner according to the outer periphery, It can be done without fail.

Another viewpoint of the floor plan is that when the building has a very large planar shape (extremely large span building), the size (radial length) in which the outer peripheral portion and the central portion can be sorted is constructed. By designing, designing, and constructing with the limit of (a), the construction limit caused by the size can be solved. When the construction plan is determined as described above, the construction of the foundation and the outer frame 16 of the building is first advanced, and travel facilities are prepared. The preparation of the traveling equipment referred to here is to provide a track for moving the outer peripheral edges a and b and the inner peripheral edges a 'and b' of the outer peripheral portion and means for pulling or pushing along the orbit. The specific structure is already well known as a traveling method, and is described in the patent publications and the like described in the section of the prior art, so that the illustration is omitted. However, the track of the outer peripheral edges a and b of the outer peripheral portion and the means of pulling or pushing along the track are usually provided at the joint portion of the outer peripheral frame portion 16 with the roof frame. For this reason, the construction process of the outer skeleton portion 16 usually precedes the construction process of the roof frame. Even in this case, the conditions for starting the construction process of the roof frame after the construction of the outer frame 6 has been completed are not necessarily limited. For example, starting from the construction work yard of the roof frame, the construction of the outer frame 16 is progressed in the traveling forward direction, and the construction of the roof frame is performed immediately after the construction of the outer frame 16 in accordance with the progress of the construction of the outer frame 16. You can also proceed. Further, as in the invention described in the above-mentioned Japanese Patent Publication No. 5-27733, if a temporary support is built outside the outer frame 16 and a traveling track and traction means are provided on the temporary support, the outer frame can be provided. The construction process of the roof frame can be advanced independently of the construction process of No. 16.

On the other hand, the inner peripheral edges a ', b'
The trajectory and the means of traction or extrusion along the trajectory are typically provided to move along the outer periphery of the central portion. For this reason, as a general theory, the construction process of the central portion precedes the construction process of the outer peripheral portion. However, even in such a case, the construction process of the center side portion is defined as the construction process of the outer peripheral portion ~ by temporarily constructing a temporary support and providing a traveling track and traction means along the inner peripheral edge of the central portion. It is also possible to implement a construction method that cuts off and advances independently.

In the case of the second aspect of the present invention, the construction of the center side portion of the roof frame is such that it can be easily understood in FIG. (The position as shown in (2)), a vent gantry is tentatively installed, a relatively small heavy machine is used to construct the steel frame, and the roof and ceiling are completed. Then, after the center portion or the center is completed, the vertical lifting or lifting equipment 7 is temporarily provided to the original height position of the center portion or the limit to carry the vertical conveyance, and the center side is moved to the original roof position. Install the part. Therefore, even if there is a microwave passage 13 as shown in FIG. 3 as a factor of the height restriction, for example, as shown in FIG. It will never be a hindrance. However, when there is no problem such as height limitation, the work stage is constructed just below the plane of the center side from the beginning as in the conventional method, and the roof It is also possible to carry out a construction method in which the construction of the center side portion is advanced to the height position. In addition, the track and the traction means for traveling with respect to the inner peripheral edge of the outer peripheral portion described above are also prepared in advance during the work of building the central portion at the ground level as necessary.

In the case of FIG. 2, a roof steel construction yard 8 and a roof and ceiling finishing yard 9 are provided in the plane of each of the outer peripheral portions of the roof frame in the case of FIG. That is, the outer peripheral portion of the upper side in the figure is at the right end position, the outer peripheral portion of the lower side is at the center position of the fan, the outer peripheral portion of the left side is the upper side end position, and the outer peripheral portion of the right side is the upper side end portion. Is provided adjacent to the roof steel yard 8 on the outer peripheral portion so that a crane can be commonly used. The roof and ceiling finishing yards 9 are provided at portions adjacent to the traveling progress side of the roof steel building yards 8, respectively.

As shown in FIG. 3, the number of cranes 10 for steel frame construction is set in the roof steel frame yard 8 so as to cover the working range over the entire length in the inward and outward directions.
Of course, each crane 10 is considerably taller than the height position of the roof frame due to the necessity of work. A temporary support 11 (bent gantry) is erected on the roof steel frame yard 8 as shown in FIG. 3, and a steel frame erection stage 12 is prepared thereon, and the steel frame of the roof frame is assembled on the stage 12. Do. Similarly, a roof and ceiling finishing stage is provided on the temporary roofing and ceiling finishing yard 9 using temporary columns. And
On the roof steel frame assembled in the front roof steel building yard 8, the finishing work of the roof (mounting of roofing material, etc.) and the ceiling (mounting of ceiling material, etc.) is continued. The roof portion completed in each work yard is sequentially traveled in the direction of the arc along the outer peripheral edge and the inner peripheral edge by the constructed length, and the construction of the outer peripheral portion proceeds as a series of operations. In performing the traveling, the outer edges a and b
FIG. 5 shows the speed and amount of movement of the inner peripheral edges a ′ and b ′.
Smoothly rotating along an arc while controlling with the system shown in (1).

By the way, in the case of FIG. 3, the outer peripheral portion of the upper side in the figure is constructed with the roof and ceiling finishing yard 8 at the right end position.
Starting in the direction of arrow E. The lower part of the outer periphery is built on the roof steel yard 8 located in the center of the fan.
From the left and right in the direction of arrow F. The construction of the outer peripheral portion on the left side is started from the roof steel frame yard 8 located at the upper side end, and is advanced in the direction of arrow G. The construction of the outer peripheral portion on the right side starts from the roof steel frame construction yard 8 located at the upper side end and proceeds in the direction of arrow H. In short, in the example of FIG. 3, the construction of the outer peripheral portion is complexly advanced in parallel at a total of three locations (substantially four locations). Therefore, the construction period can be shortened and the work can be leveled.

In addition, in parallel with the step of building the roof frame, a step of building a lower frame can be performed on the above-ground portion in the plane of the roof. Next, the embodiment shown in FIG.
The case where the plane of the large span building has a concentric circular shape in the outer peripheral portion, the outer peripheral edge and the inner peripheral edge of the outer peripheral portion, and the outer peripheral edge of the center side portion is shown. In this case, sorting of the outer peripheral portion and the inner portion can be performed relatively clearly and easily. In the case of FIG. 4, a pair of the roof steel frame yard 8, the roof, and the ceiling finishing yard 9 shows an example in which two places are provided at approximately 180 ° symmetrical positions in a circle, but one place may be used, or It is also possible to efficiently construct by installing more than one place.

In the case of the construction in which the circles are sorted as in the embodiment of FIG. 4, the traveling of the outer peripheral portion of the roof frame is rotatably supported by a column temporarily provided at the center of the circle. It is also possible to implement a method in which the inner peripheral edge of the outer peripheral portion is integrally joined to the outer peripheral edge, and the outer peripheral portion and the center side portion are integrally rotated in synchronization with the progress of the construction process.
