Research on the construction technology of precast building PC component formwork
Taking the column component as an example, technicians should do a good job in the blanking of reinforcement according to the reinforcement layout of the column component, and scientifically and reasonably design the size of reinforcement.
There are certain risks in the transportation of PC component formwork.
The construction amount involved in the construction link is small, and the construction process will not pollute the surrounding environment.
After the concrete structure is formed, the production personnel should take out the hole formwork on both sides, but because the hole formwork is located inside the structure, Therefore, the demolition process is more troublesome.
In order to ensure that the size, specification and quality of each cast PC component meet the requirements of engineering construction.
2 new precast building PC component formwork fabrication during the construction of precast building engineering, PC components are mostly concrete precast components, including precast beam concrete components, precast floor concrete components, precast foundation concrete components, etc.
If there are quality problems in the production process, they should be solved in time to avoid the production of PC component formwork with quality problems, which will affect the subsequent construction.
First set the connecting sleeve on one side of the reinforcement, then place the reinforcement cage on the component production line, and fix the connecting sleeve above the formwork through screws to ensure accurate positioning.
Before applying the release agent, first clean the mold surface to ensure that there is no dust or impurities on the surface, then apply the anti rust agent to the surface, and finally apply the release agent to give full play to the important role of the release agent..
(2) The high quality of components is mainly reflected in the advanced and efficient production technology involved in the production process of PC components, and the production equipment is professional high-performance production equipment.
Managers should do a good job in the supervision and control of transportation links from the perspective of PC component formwork transportation, so as to make the transportation process faster and more efficient and avoid safety risks, so as not to affect the quality and structural performance of PC component formwork.
During the production period, the production personnel should also develop a good awareness of quality control.
Finally, bolts shall be used to connect the side formwork with the bottom formwork.
1.2 key points for the application of PC component formwork of new cast buildings since PC component formwork is uniformly manufactured by the factory, the manufacturer needs to have certain production conditions, such as production facilities, production technology and plant area, and can start the production of PC component formwork only after ensuring that all elements can be implemented in place, so the initial cost is high.
(3) The structural production efficiency is mainly reflected in that when the size and specification of PC component formwork are determined, the production process and installation process are very standardized, which can greatly improve the installation efficiency.
At this stage, the formwork removal is mostly handled manually, which will greatly increase the difficulty of demoulding, and the demoulding efficiency can not be guaranteed, affecting the subsequent engineering construction.
Therefore, the requirements of all parties of PC component formwork can be guaranteed, and the product quality is superior.
3.4 release agent the application of release agent can quickly remove the concrete from the top of the formwork after solidification.
(1) The superior safety performance is mainly reflected in that the component formwork is uniformly manufactured by the factory according to the contents of the drawings and relying on the rigorous production process, with high production technology level, strong stability of production links and no safety accidents.
(4) The low construction cost is mainly reflected in that the mold structure is a kind of tool that can be reused for many times, so the production cost is low.
3.3 the mold installation and inspection technicians shall timely clean the side formwork and bottom formwork, and install the formwork on both sides based on the actual situation of the mold.
Relevant technicians shall design corresponding mechanical demoulding device according to the actual situation of cast PC components to improve the efficiency of demoulding link.
(5) The good environmental protection of the construction link is mainly reflected in the application process of PC component formwork.
However, it should be noted that in order to give full play to the function and role of the mold structure, quality control should be done well during the manufacturing of the mold structure to make the manufacturing link more standard, which is a key management content.
3.2 rebar binding and casing positioning rebar binding and casing positioning can directly affect the production quality of cast PC components.
In addition, there is no need to use too many construction materials in the construction process, so as to avoid the problem of waste.
It can be seen that the production link of PC component formwork is the basic factor affecting the construction quality of precast PC component production and subsequent construction links.
Secondly, when the production is completed, it shall be transported to the construction site.
The production personnel shall ensure that the specification and size of formwork tools meet the production requirements of precast PC components, improve the production quality of precast PC components, strengthen the construction effect of precast concrete engineering, and promote the sustainable development of China’s construction industry.
Based on the contents of the design drawings, judge whether the size of the formwork after installation meets the engineering construction requirements, and then start the next process.
The production personnel of precast PC components shall do a good job in formwork production to ensure the accuracy and production efficiency of concrete components.
In order to reduce the initial cost expenditure and improve the convenience of PC component formwork production, before the production of PC component formwork, corresponding planning and management should be done to make all production personnel master the operation methods of relevant equipment and the application points of production technology, and organize corresponding training and exchange activities to ensure that the comprehensive ability of production personnel meets the production standards of PC component formwork.
Common formwork is mainly composed of side and bottom formwork and reserved hole formwork.
1 overview of precast building PC component formwork 1.1 application advantages of new precast building PC component formwork expounds that the application advantages of new precast building PC component formwork are mainly reflected in five aspects: superior safety performance, high component quality, high structural production efficiency, low construction cost and good environmental protection in construction links.
During installation, the side formwork shall also be positioned.
3 production of new precast building PC components 3.1 mold design during the production of precast building PC components, various parameters of the formwork structure are closely related to the specifications, models and dimensions of precast PC components.
