Building closure network How to construct?

The leakage of underground structures such as foundation slab construction joints is a common quality problem in construction. On the one hand, the construction joint garbage is not cleaned up, which makes the concrete combination of two times is not dense; the vibration is not dense during pouring, resulting in hole cracks; the maintenance is not timely, and the temperature difference stress leads to local cracking of construction joints. On the other hand, the construction technology defects of water stop steel plate itself lead to poor construction quality of construction joints and leakage.
 
Through the inspection of the construction joints of the floor in the past projects, it is found that the construction process defects of the water stop steel plate are different degrees; the vibration is not dense and the vibration is missing; the garbage is not cleaned up; the construction joint treatment method is not in accordance with the jumping warehouse method, which causes the construction quality hidden danger.

In order to ensure the construction quality of foundation slab construction joints and avoid leakage caused by construction quality problems, the paper analyzes and implements corresponding countermeasures, and achieves good results, which is worthy of reference. The construction area of the foundation slab of the project is about 80000 m2, and the construction joint length is more than 4500m.


Because the basement floor adopts the skip warehouse method, the post pouring band is cancelled, and only the construction joint is reserved for one-time pouring. The above figure shows the detailed node design of the construction joint of the skip warehouse. The construction steps are as follows: installing double-layer bidirectional bottom reinforcement at the bottom of the base plate → installing the lower φ 12 temperature reinforcing bar → installing the water stop steel plate, welding and fixing → installing the double-layer bidirectional reinforcement on the upper part of the bottom plate → installing the upper φ 12 temperature Stiffeners. The details are shown in the above figure; and the site investigation problems are easy to be found in the construction of water stop steel plate.
 
According to the construction defects of water stop steel plate, the improvement ideas are determined
 
The steel bar framework is directly welded with φ 10 on the top and bottom of the water stop steel plate, and the steel wire mesh is bound. Through calculation, the thickness of the bottom plate protective layer, the diameter of the bottom plate reinforcement and temperature steel bar are removed. The height of the upper and lower framework is 13.4cm, and the support spacing is 300. During installation, it is welded to the upper and lower reinforcement of the bottom plate.
 
The one-time molding can completely control the requirements of the middle setting of the water stop steel plate, ensure the thickness requirements of the protective layer, intercept the fresh concrete, and play a supporting role.
 
It is expected that half of the water stop steel plate will be embedded in the concrete, and half of the steel plate will be exposed; there will be no large amount of concrete seepage, which will save concrete, reduce the amount of chiseling, and facilitate the cleaning of construction joints, and the construction joint joints are better.
