First, the film faced plywood structure
The so-called film faced plywood is a large film faced plywood or a short film faced plywood film faced plywood, as a tool-based film faced plywood, which is based on the construction needs and characteristics (in accordance with the concrete structure and component design requirements of the size of the model board.) Developed Can be used for continuous and periodic use of the film faced plywood, and film faced plywood technology is the use of these large or large film faced plywood to form a whole, to protect the quality of construction work. For the film faced plywood, the block area is large, and the box frame and the combination of steel film faced plywood is different, under normal circumstances, one side of the wall is generally only a film faced plywood, in addition, the film faced plywood structure is also from the ordinary small open shear Wall works gradually developed into a large-scale shear wall works, and in the framework of the shear wall and box-type infrastructure has a wide range of applications. For the film faced plywood engineering structure, its type is more, both inside and outside the wall are all cast-in-place concrete all-cast structure, there are external walls for the brick inside the brick structure, the interior wall is the structure of the cast-in-place concrete.
Second, the composition of the film faced plywood
The film faced plywood is a professional design and industrial processing made of a tool-based film faced plywood, generally with the bracket as a whole. Because it is significant, the construction should be accompanied by the corresponding lifting and transport machinery, is the building of the room, into the depth, layer-based film faced plywood design, production, film faced plywood as the main means of construction to cast-in-place reinforced concrete wall As the leading process, the organization has a rhythm of the balanced construction. The film faced plywood system mainly includes four systems, namely, panel system, support system, operating platform system, accessory system, etc., the four systems, the panel system for direct contact with concrete, the use of transverse ribs and vertical ribs as a skeleton to accept the panel Pressure; support system consists of support frame and anchor bolts, used to withstand the pressure brought by the wind and the ground parallel pressure to maintain the stability of the entire film faced plywood project; operating platform system is used to build construction workers in the place, the main Including scaffolding and tripods, as well as iron ladder and protective measures; accessory system refers to other film faced plywood accessories system.
Third, the film faced plywood construction process characteristics
(A) construction convenience
High-rise building construction, the technical convenience, can achieve a substantial increase in construction efficiency and the effective reduction of construction costs. For the film faced plywood technology, it is able to do this effectively to meet the requirements of the film faced plywood technology in the construction, can be a simple installation and removal, compared with some small mold, the film faced plywood technology in the combination of installation More convenient, do not need to manage and install each small film faced plywood to complete the work, which can save a lot of working hours, making the construction period to be guaranteed.
(B) looks good
For small film faced plywood, in the application, the need for installation and removal of special attention to prevent the film faced plywood between the inequality and the gap between the film faced plywood problems, to the entire building shape and appearance of adverse factors. However, when the film faced plywood technology is applied, it can be effectively avoided for such problems, since it is itself a whole for the film faced plywood, so it is not necessary to carry out a wide range of joints as a small film faced plywood , So that the film faced plywood in the high-rise building construction applications, the specific good overall, and to be able to guarantee the quality.
(C) a longer life span
In the construction process, the life problem is one of the issues that must be taken into account. By comparing the film faced plywood and the small film faced plywood, the film faced plywood can be used for a long time and can continue to be used after it has been used up. In addition, for the film faced plywood, it is generally made of steel and other building materials, so in the course of use, will show a better durability.
(D) low cost
In the construction process, in addition to the useful life and construction period, the construction costs also need to be considered, especially in the application of the film faced plywood, not only need to consider the efficiency and durability of the film faced plywood, but also on the film faced plywood The cost to be considered. For the film faced plywood, it can be used in the application of the effective cost savings, so when used in its use, can be effective to reduce the cost of construction. In addition, the film faced plywood to apply, but also can undertake a large number of structures and plug-in facilities, so the cost control has a greater role.
Fourth, the advantages of the film faced plywood

Fifth, the shortcomings of the film faced plywood
With the film faced plywood technology in the high-rise building construction in-depth use, the drawbacks are gradually prominent. Disadvantages are also obvious: the film faced plywood docking process of the joint defects, the difficulty of the installation and removal of the film faced plywood and the bottom of the film faced plywood slurry, there is a large self-weight, high consumption of steel, the relevant data show that up to 110Kg per square meter. According to the previous project data, in the high-rise shear wall system to reach 500m2 area, the number of steel mold lifting to reach the total standard level of about 35%. Resulting in a larger loading and unloading workload, while the larger area makes it bear greater wind power. Not only need a larger one-time investment, but also because of the larger area of the film faced plywood, the requirements for the yard corresponding higher, so there are many deficiencies in versatility. Based on this, the film faced plywood system in the application of high-rise buildings subject to a lot of restrictions. Such as the construction of the same high-rise buildings, you can increase the stamping rate of the film faced plywood. The emergence of these problems, the convenience of construction and safety have a significant impact.
