（考案が属する技術分野）
本考案は、膜体構造物における膜体の接合部の
構造に関するものである。[Detailed description of the invention] (Technical field to which the invention belongs) The present invention relates to a structure of a joint portion of a membrane body in a membrane structure.
（考案の目的）
近時、膜体構造物が普及しつつあり、その規模
は益々大型化する傾向にある。(Purpose of the invention) In recent years, membrane structures have become popular, and their scale tends to become larger.
ところで、この膜体構造物は膜体を空気圧で支

合部にも気密性と強靱性が要求されるが、従来の
膜体の接合部は、膜体の端部を重ね合わせてこの
重合部を溶着しただけであり、気密性と強靱性の
点で不安があつた。 By the way, this membrane structure has a structure in which the membrane is supported by air pressure, so not only is the membrane itself required to be airtight and tough, but the joints between the membranes must also be airtight and tough. Toughness is required, but conventional membrane joints simply involve overlapping the ends of the membranes and welding the overlapping parts, which raises concerns about airtightness and toughness.
本考案は、前記実情に鑑み、気密性と強靱性の
点で信頼できる膜体構造物における膜体の接合部
を提供すること目的としているものである。 In view of the above-mentioned circumstances, the present invention aims to provide a membrane joint in a membrane structure that is reliable in terms of airtightness and toughness.

た点にある。(Structural features of the invention) The structural features of the joint portion of the membrane body in the membrane structure of the present invention are that each end of one membrane body and the other membrane body are overlapped, and this overlapping part is formed. At the same time as welding, a reinforcing membrane body wider than the overlapping part is overlapped on the outside thereof, and both sides of the reinforcing membrane body protruding from the overlapping part are welded to one membrane body and the other membrane body, respectively. .

着３されている。(Specific explanation of the invention) In FIG. 1 showing an embodiment of the invention, 1, 2
is a membrane body for constructing a membrane structure, which is made of a thick woven fabric such as canvas that has been treated to be waterproof and airtight.The ends of membrane bodies 1 and 2 are overlapped, and this overlapping part Welded 3.
４は膜体１，２と同質の補強膜体であり、その
巾は膜体１，２の重合部の巾よりも大である。 Reference numeral 4 denotes a reinforcing membrane body of the same quality as membrane bodies 1 and 2, and its width is larger than the width of the overlapped portion of membrane bodies 1 and 2.

上のようなものであるから、次のような諸効果が
期待できる。(Effects of the invention) Since the joining portion of the membrane in the membrane structure of the invention is as described above, the following effects can be expected.
一方の膜体と他方の膜体の各端部を重合して溶

保持が確実であり、仮に補強膜体の溶着部が破損
されても主接合部により接合部の気密性と強度を
維持することができ、また、仮に主接合部の溶着

度を維持することができる。 In addition to the main joint where the ends of one membrane body and the other membrane body are overlapped and welded, a sub-joint part made of a reinforcing membrane body is formed, so that the airtightness and strength of the joint part can be maintained. It is reliable, and even if the welded part of the reinforcing membrane body is damaged, the main joint can maintain the airtightness and strength of the joint, and even if the welded part of the main joint is defective, the reinforcing membrane The body can maintain the tightness and strength of the joint.
補強膜体の中央部が溶着されていないので、こ
の部分に圧気を注入して溶着に欠陥があるか否か
をチエツクできる。 Since the central part of the reinforcing membrane is not welded, it is possible to check whether there is a defect in the welding by injecting pressurized air into this part.
補強膜体の中央部が溶着されていないので、接
合部の剛性がさほど大きくならず、取り扱いに便
利である。 Since the center portion of the reinforcing membrane body is not welded, the rigidity of the joint portion is not very large, making it convenient to handle.
