Position.By setting up limiting plate, further make deck with deck para-position accurately, improve the reliability of connection.
The attachment means also include I shape limited support, be provided with and coordinate with the bolt in the middle part of I shape limited support
Bolt hole, when between deck and deck pass through bolt, nut check when, the I shape limited support is positioned by bolt hole
In the bolt, two decks spacing keep alignment by the both-side opening of the I shape limited support.By the I shape
Limited support, can equally improve the accuracy of deck and deck para-position.
The I shape limited support is provided with the cover lid of disjunctor, when I shape limited support is positioned at the bolt, cover
The lid masking bolt, nut.By arranging cover lid, certain dustproof and waterproof effect is played to bolt, nut,
Support member described in uniform at least two between the pre-manufactured steel chimney shell ring outer wall and outer tube inner wall, and support member is in
U-shaped, the opening welding outer tube inner wall of the U-shaped support member, arc end weld pre-manufactured steel chimney shell ring outer wall.Supported by U-shaped
Part is supported, and not only firmness and reliability are high, and according to the gap length between pre-manufactured steel chimney shell ring and outer tube, by adjusting
U-shaped opening size is adapted to so as to which connection is using more convenient.
The sealing member is sealing gasket or fluid sealant, realizes the sealing between contiguous prefabricated steel stack shell ring.
This utility model simple structure, dismounts more convenient laborsaving, connection reliability height, is difficult to loosen and deforms, be suitable for
In the connection of pre-manufactured steel chimney shell ring, or the structure of similar attachment means is improved.
