Description

DETAILED DESCRIPTION OF THE INVENTION This article relates to method #C for constructing a rope skeleton dome used in a food-based baseball bat, etc.

A conventional method for constructing this type of mesh skeleton dome is to proceed inwardly and upwardly from the base circumference until reaching the final skylight. However, in the case of this construction method, the construction work position becomes higher as the dome moves upward inside the dome, so the construction period is shortened without the inconvenience and danger of lifting and joining the tengoku panel or each rod material. The situation could not be avoided for a long time.

This invention was proposed in light of the above circumstances, and its purpose is to provide a construction method that provides high work safety and shortens the construction period.

The construction method related to this development is based on Hei II, which was divided into Zhoufangang.
A method for constructing a #18 skeletal dome, which is constructed from a number of fan-shaped unit dome parts, and each unit dome is formed from a central dome part and 15 parts of 1111 wax, and the dome center sK 7 tops. A lift-up column capable of supporting the side wall dome S is movably erected together with a central column ε, and the side wall dome portion is assembled and supported on the lift-up column with the side wall dome part opened slightly more than when completed. The unit dome is assembled by assembling the central dome near the ground and lifting it up using the lift-up center column and the lift-up column.Then, the lift-up column is moved to the next unit dome assembly position and the next unit is assembled. The dome is assembled, and the dome is constructed by sequentially assembling such unit domes, and the entire assembly is performed near the ground.

The present invention will be described below based on an illustrated embodiment. #1111. As shown in Figure 2, the mesh skeleton dome D
is composed of a large number of unit domes sDU having a regular planar shape divided in the horse direction, and this unit dome portion DTI includes a central dome sDυ1 having a substantially trapezoidal planar shape and a @wall dome portion j172 having a substantially trapezoidal planar shape. formed from the center of the dome s
K stands in the center of the dome, and the central column 1 for top up is erected so that its head protrudes from the dome when completed.
Even if a pair of lift-up columns 2 capable of supporting the dome Iku D1]2 are movably erected. The pair of lift-up columns 2 are the center door A@ntr1 and II! 1 m1 do A @ D v 2 J knee f) contact klf.

It is placed at both ends of the section and its height is ll so that it can be moved. I can do it. This support column 2 may be pressed so that it moves on wheels on a guide rail, or it may be moved using wheels on its own.

f) In such a configuration, a concrete foundation 4 with a triangular cross-section is poured, and a truck crane (not shown) uses a support 5 to construct a 'C@Wall Dome@J) U2. Assemble.

The assembled @wall dome DU2 is opened more open than when completed by the jacks 6, and its WaS portion is supported by the lift-up struts 2.

The lift-up central column 1 has a tower crane 7 inside.
It has a hanging tool 8N- which is supported so as to be able to move up and down. Assemble the central dome part ptrl near the ground using the support 9, and hang the hanging JIL10 and K attached to the hanging tool 8 and the lift-up column 2. Therefore, the central dome part J)
Lift up Ul.

The pressing force of the jack 6 is released and the end of the central dome part Dυ1 and the end of the side wall dome part DU2 are connected to form a unit dome D.
U is assembled. Here, a connecting member 11 may be interposed between the ends.

Next, the head of the ref-F-up strut 20 is retracted and moved to the next assembly position to assemble the next unit dome portion Dυ, and this process is sequentially repeated to construct the dome D. Here, as for the assembly order of the unit dome part DU, it is desirable for balance to assemble one unit dome part Dυ and then assemble the opposing unit dome part J)U as shown in Figure II/45.

As mentioned above, according to this invention, the domes can be reliably constructed one by one without moving the dome itself, and the assembly work can be done near the ground, which improves the safety of the work and shortens the construction period. I can figure it out. This method is effective in constructing Oboro Dome, as it requires almost no high-lift cranes.

Claims (1)

[Claims] (1) Method for constructing a mesh skeleton dome, which is composed of a large number of flat layered unit dome parts divided into squares, and each unit dome part is formed from a central dome part and side wall dome parts. A central lift-up support pillar was erected in the center of the dome, and a 7-top support pillar was moved to support the side wall dome part, and the side wall dome part was assembled. After supporting the V7 top up support with a slight opening, the central dome is assembled near the ground and raised by the lift up central support and the lift up support to assemble the unit dome, and then the V7 top up It is better to move the support support to the next unit dome assembly position and assemble the next unit dome, and then assemble the unit domes one after another to construct the dome.
