- the present invention relates to a membrane anchor mechanism.
- This application claims priority based on Japanese Patent Application No. 2013-236944 for which it applied to Japan on November 15, 2013, and uses the content here.
- a membrane anchor mechanism is used to hold against the concrete wall via a heat insulating material in order to maintain the shape of the membrane with low rigidity.
- the structure to support is used (for example, refer patent document 1).
- Various types of tanks are used as such membrane-type low-temperature tanks.
- tanks having a corner portion such as a square shape or a cylindrical shape are also widely used.
- Patent Document 2 discloses a membrane anchor mechanism that supports a membrane panel (corner membrane panel) installed at a corner portion of a low-temperature tank.
- Such a membrane anchor mechanism disclosed in Patent Document 2 is installed at a boundary portion of a haunch structure portion provided at a corner portion, and supports an edge portion of the corner membrane panel.
- the haunch structure as described above is not necessarily provided in all the low temperature tanks having the corner portion. For this reason, a membrane anchor mechanism as disclosed in Patent Document 2 cannot be employed for all low temperature tanks. Moreover, in the membrane anchor mechanism in which the support location is limited to the edge of the corner membrane panel, it is not possible to perform an arrangement such as pressing the center of the membrane panel.
- the membrane anchor mechanism is a structure in which the heat insulating material can be easily arranged even in the place where the membrane anchor mechanism is installed. It is desirable.
- the present invention has been made in view of the above-described problems, can support the corner membrane panel regardless of the presence or absence of the haunch structure, and can suppress a place that is not limited to the edge of the corner membrane panel. It is another object of the present invention to provide a membrane anchor mechanism that can easily arrange a heat insulating material around it.
- the present invention adopts the following configuration as means for solving the above-described problems.
- a membrane anchor mechanism for fixing a metal membrane provided on the inner wall surface side of a concrete wall via a heat insulating material to the concrete wall in the low temperature tank, wherein the concrete anchor A rod-like leg portion standing on the wall, an anchor supported by the leg portion in a state of being separated from the concrete wall and inserted into a through-hole penetrating the heat insulating material and the membrane, and the through-hole And a pressing part that holds the membrane and is fixed to the anchor that is exposed through.
- the membrane in the first aspect, includes a corner membrane panel that is a curved membrane panel disposed in a corner portion of a low-temperature tank, and forms the corner portion.
- the leg portion is erected with respect to each of the plurality of inner wall surfaces of the concrete wall, and the pressing component holds the corner membrane panel.
- the pressing component is disposed so as to press the center position of the thermally deformed portion of the membrane panel forming the membrane.
- the membrane anchor mechanism is provided in a base part to which the leg part is connected, the base part, and the anchor. And a joint that is rotatably supported.
- the leg portion includes a stud bolt provided at both ends and a long nut to which the stud bolt is screwed.
- the anchor is attached to the rod-like leg portion standing on the concrete wall.
- the leg part and the anchor separate, it becomes possible to easily change the attachment posture of the anchor to the leg part. Therefore, by adopting the mounting posture of the leg portion and the anchor according to the formation position of the through hole, even if the through hole penetrating the heat insulating material and the membrane is provided at any position, The anchor can be easily arranged at a position where it can be inserted into the through hole. Since the pressing part is fixed to the anchor inserted through the through hole and the membrane is pressed by the pressing part, according to the present invention, the position of the through hole is arbitrarily set, and the membrane A place can be held down.
- the membrane anchor mechanism can be installed regardless of whether or not the haunch structure is provided on the concrete wall. Furthermore, since the anchor is supported by the rod-shaped leg portion, a large space is formed between the anchor and the concrete wall. For this reason, a heat insulating material can be easily arrange
