Technical Field
The invention relates to the field of building construction methods, in particular to a method for fixing an angle steel piece for pulling and connecting a wall top and a beam or a plate of a filler wall.
Background
The atlas (12G614-1) 'masonry infilled wall structure' is implemented in 2012 and is not updated, wherein 16 pages of the nodes are rarely applied in construction about the iron member tie method of infilled wall tops and beams (plates), almost the nodes are famous and rare, construction site call in each building field is always high, and a practical and simple construction method is required to replace the node.
However, in reality, the beam width is different or even different, and the connecting pieces (iron pieces) are different, so that the method has the following defects:
1. the blanking of iron parts has multiple specifications, causes that the special-shaped iron parts are too many and can not correspond to various wall tops on site one by one, and is very easy to cause the confusion of construction and construction management.
2. The length of some iron pieces for clamping the width of the beam is too long and the rigidity is insufficient, so that the anti-seismic effect cannot be achieved.
3. A large amount of walls can not be placed in the middle with the roof beam, lead to about the ironware not placed in the middle even take place very big dislocation, take place when the wall runs to the condition on roof beam limit, connect the position and overlap very little, whole shock resistance is poor.
4. The upper and lower iron pieces are inconvenient to weld and difficult to ensure the construction quality.
5. There is no explicit tie of the wall top to the panel (actually reproducing the fact that there are many points where the wall top contacts the panel), nor is there an explicit tie of the wall top to the beam, if not centered, even running to the beam edge or out of the beam.
6. No provision is made for correcting a wall that has been built to the top but is unsatisfactory.
Therefore, a novel method for fixing the tied angle steel piece between the wall top of the infilled wall and the beam or the plate is needed to be designed for tying and fixing, and the original method is replaced.
