读了本刊1998年第1期《砖墙敷设线管剔槽新法》一文后,本人有以下看法。该文谈到墙体砌筑中及时勾出一定深度的灰缝,待砂浆有一定强度后,再进行剔凿。本人认为240毫米厚砖墙利用这种方法,顺其砖缝剔槽是完全可以的,但120毫米厚砖墙利用此法,就存在以下几点不足。(1)因为120毫米厚砖墙砌筑为工字缝,剔槽时存在从整块砖中间剔槽,很不容易剔出理想的管槽。
After reading this article in the first issue of the 1998 issue of “The new method for laying pipes on a brick wall”, I have the following views. This article talks about cracking a certain depth of mortar joints in the wall masonry in time, and after the mortar has a certain strength, cuts it again. I think 240mm thick brick wall using this method, it is completely possible to tick the bricks, but the 120mm thick brick wall using this method, there are the following deficiencies. (1) Because the 120mm thick brick masonry is an I-shaped seam, there is a culling from the middle of the whole brick during the ticking, and it is not easy to eliminate the ideal pipe trough.
