one. Template assembly rule
Reinforcement of shear wall formwork is an important part of building construction and plays a vital role in the quality of the project. The assembly rules are as follows
The assembly of the formwork should be assembled into a whole according to the size of the template plate. When assembling on site, it is necessary to control the joint between adjacent plates, and the joints of the beam and plate should be treated with anti-seepage measures to prevent leakage. Assembly accuracy requirements are as follows:
1. The joint between two templates is ≤1mm
2. The height difference between adjacent templates is ≤1mm
3, template flatness ≤ 2mm
4, template plane size deviation ± 3mm
When the span of the cast-in-situ beam is greater than or equal to 4.0m, the arch is lifted by 2‰. When the length of the cantilever beam is greater than 2.0m, the arch is spanned according to the span of L/200, and the arch height is not more than 20mm.
Pallet wall template matching principle: long side package short side, the template should be horizontally matched as much as possible, the size must be accurate.
Two . Shear wall formwork reinforcement support system selection criteria
In the process of template assembly, in addition to strictly following the above operational specifications, the shear wall formwork reinforcement support system should be correctly selected. The selection criteria are as follows:
1. The primary and secondary keel steel back splicing is accurate, ensuring the average performance of the building body and high toughness.
2. The primary and secondary keels are used together, and the joint surface is evenly stressed and the deformation is consistent.
3. The main keel, the yin and yang angle, the porous plug lock, keep the same horizontal line, the average horizontal tension.
4. The overall rigidity, strength, horizontal load force and stability of the frame system are good.
5. The support structure is simplified, the setting procedure is convenient, the construction operation is simple, the speed is fast, and the construction cost is saved.
Changli Tianjian Industrial's new shear wall formwork reinforcement technology, the main keel is welded by two square pipes of the same cross-section and the secondary keels used in conjunction with them are steel square structures, the joint surface is evenly applied and the construction effect is good.
The intersection of the main and secondary keels is contacted by the original "point" and becomes "face" contact. The contact area is large and the force is even. The main and secondary keels are of the same material and have the same deformation. Thereby increasing the strength and rigidity of the template. The flatness deviation of the concrete surface can be controlled within 2mm.
The two horizontal bars connected at the corner of the corner are reinforced with a positive angle lock, which is more firm and not easily deformed. The angle lock is used for reinforcement of the corner of the shear wall and the opening of the hole. The connection is convenient because the ends of the bar are in the same The horizontal plane, so after reinforcement, the 90° angle of the positive angle is guaranteed.
The formwork support has greater bearing capacity, and the rigidity and stability are greatly enhanced. It can reliably withstand the self-weight and side pressure of the newly poured concrete, as well as the load rise force generated during construction, and effectively solve the problem of template joint running.
