The PVC pipe of appropriate size is embedded inside the installation joint, which can well eliminate the air in the grouting silo and the grouting sleeve, ensure the grouting quality, and effectively prevent the setting slurry of sealing the silo from being squeezed into the grouting silo to block the precast laminated plate “8” of the grouting sleeve The “eight” shaped tongue and groove joint is reserved at the joint position of two precast laminated plates.

Excellent quality and low cost? The balcony edge protection shall be deepened in advance in combination with the position of balcony railing column, and anchor plates shall be embedded at this position to ensure the safety of edge protection during the construction stage of the main structure and reduce the protection cost of the project.

035 technical applications for utility model patents for precast external wall embedded grouting The grouting observation hole uses the principle of connector and the high fluidity of grouting material to ensure the grouting quality of grouting sleeve and grouting chamber, which can save a lot of cost and testing time, Simple operation, aluminum mold C slot as the edge support of precast laminated plate effectively solves the problems of complex layout of precast laminated plate edge support, collision between precast laminated plate support system and aluminum mold support system, and reduces the separation of precast laminated plate support materials and precast external wall grouting silo The construction method of sealing the silo is to use special setting slurry in the middle of the wall to partition the grouting silo.

The construction process is simple.

At the same time, it installs LED energy-saving lighting belt to avoid the collision between the lifting components and the climbing frame during the hoisting construction at night, so as to improve the safety management level of the project.

By analyzing the characteristics of precast buildings, combined with the aluminum formwork climbing frame system and referring to the company’s integrated construction and process interleaving guide, the project process interleaving model is established to save the construction period of about 3 months.

The project is located in Shangjian village, Jinhua Town, guanshanhu District, Guiyang City, with a total construction area of 142000 square meters, of which 1#~6# building is a cast structure residence, with a total assembly area of 70000 square meters, a prefabrication rate of 31.22% and a cast 57.75% 01.

The construction period is shortened by 3 months? The main precast components of the project are precast external shear walls, precast balconies, precast stairs, laminated plates and precast light internal partitions.

It only needs to support and remove the formwork in the basement, which can turn waste into treasure, save the project cost, and realize the waterproof construction of the outer wall of the basement, basement foundation pit backfilling Outdoor ancillary works interspersed in advance can advance the construction period of basement foundation pit backfilling and outdoor ancillary works by about 1 month.

The project installs a spray system on the climbing frame to improve the dust reduction effect, but also ensure the concrete curing.

Recently, the civil construction of Shangjian resettlement house, the first large-scale cast high-rise building project in Guizhou Province built by the first company of China Construction Third Bureau (including cast building) The completion acceptance of bid section I is successfully completed.

After the hoisting is completed, it is filled with crack resistant mortar to effectively solve the problem of slurry leakage at the joint position during the concrete pouring of the cast-in-situ layer of the laminated plate and the cracking of the decorative surface at the joint position of the laminated plate For quality problems such as water leakage, the precast reinforced concrete slab is used to seal the outer wall of the basement in advance, and the post cast strip precast reinforced concrete slab is used as the outer formwork.

The internal partition wall of the standard floor adopts light aerated concrete strip plate strength, heat insulation, sound insulation The thermal insulation performance is better, the molding quality is good, and the requirements of no plastering are met.

At present, the above five technologies have applied for utility model patents 04 and received continuous praise!
