摘要： PROBLEM TO BE SOLVED: To reduce the size of an upper cord material used commonly as a membrane material receiving member by simplifying the shape and supporting method of a membrane material and reducing the number of component members of a membrane structure so as to reduce weight and cost and also reducing a bending moment due to eccentricity between a tension of the membrane material and an axial force of a tie rod in the membrane structure in which the membrane materials are stretched on a roof frame of a space truss. SOLUTION: Truss frame materials 1 obtained by connecting upper cord materials 6 to lower cord materials 7 through strut materials 8 and web materials 9 are arranged at intervals in parallel with each other, through members 2 positioned lower than the upper chord materials 6 are arranged between the truss frame materials 1 in parallel with the truss frame materials 1, and the truss frame materials are connected to each other through tie rods 3 at the lower penal point parts A2 of the strut materials. Then the panel point parts A1 and A2 at the upper and lower parts of the strut materials 8 are connected to the through members 2 through the tie rods 4 arranged on surfaces perpendicular to the truss frame materials, the panel point position of the upper or lower chord to which the web materials 9 of the truss frame materials are connected is also connected tO the through members 2 through the tie rods 5, and membrane materials are installed tensely on the upper chord materials 6 and through members 2 of the truss frame materials using shape steels and pipe members on the upper surface of these shape steels and pipe members.

摘要： PURPOSE: To shorten a construction period, reduce cost and high elevation work greatly when constructing a relatively large-sized cantilever type roof. CONSTITUTION: When constructing a shed where a cantilever-shaped roof 1, which covers the upper part of a lower structural skeleton B of a sports stadium installed opposing separatedly to a field space, support posts 2 are erected on an outer peripheral part of the lower part structural skeleton B. The roof 1 is assembled with the lower structural skeleton B while the roof 1 is pin-joined with the support posts 2 at the base ends of the roof 1 so that it may be vertically slanted. A cable 6-A, which supports the tip of the roof 1 is respectively connected to a lifting machine 10, such as a winch. The cable is lowered by the lifting machine, thereby lifting up the roof 1.

摘要： PROBLEM TO BE SOLVED: To reduce a construction period and cost by using a base structural body in the case a roof structural body is lifted up and to eliminate an eccentric bending acting on a lift-up working platform and the base structural body in the case of lift-up. SOLUTION: A roof structural body 1 is built up on the ground, at the same time, the circumferential part (the circumferential columns 4 and circumferential ring materials 6) positioned to the outside of the circumferential tension ring 2 of a base structural body 3 for bearing the circumferential tension ring 2 thereof is all constructed, and part positioned to the inside of the circumferential tension ring 2 constructs only the inside circumferential columns 5 positioned in meshes of the roof structural body 1. Temporary working platforms 10 are mounted on the upper parts of those permanent circumferential parts and the inside circumferential columns 5, and the roof structural body 1 is lifted up with a lift-up device 20 and is raised up to a regular position. Then, the remaining part (the inside circumferential ring materials, inside and outside tie materials and brace materials) of the base structural body 3 is completed, and after the roor structural body 1 is mounted on the top section of the completed base structural body 3, the temporary lift-up working platforms 10 are removed.

摘要： PROBLEM TO BE SOLVED: To build an extremely large span frame by the use of an ordinary crane, reduce altitude works and temporary materials, shorten the construction period, decrease the cost, and improve safety. SOLUTION: The outer circumferential ring 3 and the outermost circumferential ring 2C of a large span frame 2 are built on a foundation 6, a first center part large span frame 2A and at least one intermediate part ring structure 2B are built by assembling on the ground, the first center part large span frame 2A (2-1) is elevated by suspending or the like to the end part connection height and connected to the intermediate part ring structure 2B so as to form a second large span frame 2-2, and the second large stretch frame 2-2 is elevated to the end part connection height by suspending or the like and connected to the outermost circumferential part ring structure 2C. All of 2A, 2B and 2C are provided with constraint mechanism, and by tension of the constrain mechanisms 11, fixed desin dimension is obtained and prestress is introduced to the member.

摘要： PURPOSE: To make it possible to design a roof with a small section of member in comparison with a relatively large-sized cantilever type roof such as soccer stadium, etc., and to enable safe construction against upward load suck as blowing up wind load, etc. CONSTITUTION: A cantilevered roof 1 covering upward of a lower structure skeleton B in a stadium is connected to bearing posts 2 erected to the peripheral surface of the lower structure skeleton B in the basic end of the roof with pins so as to make it possible to incline in the vertical direction, and posts 4 and 4' are connected to the front end of the roof 1 with pins so as to make it possible to incline in the horizontal direction. Cables 6-A bearing the roof 1 in the vicinity of the lower parts of the posts are respectively tensioned to the ground foundation 9 through the bearing posts 2 to resist downward load such as dead-weight, etc. Cables 6-C are connected between the upper parts of a pair of up and down posts 4 and 4', and cables 6-B from the upper parts of the posts are respectively tensioned to the ground foundation 9 through the bearing posts 2 to resist load acting upward of blowing up wind load, etc. An unstable phenomenon caused by load acting unequally on both right and left roofs with diagonal line shaped cables 6-C' in a side view can be prevented.
