by Although templates are not a part of the building entity, they are an indispensable part. As long as there is concrete wet operation, they cannot be separated from the support of templates. With the continuous increase of labor and material costs, the proportion of templates in the cost is also increasing. The construction area per square meter has reached about 200 yuan/square meter, and the proportion in the general contracting contract has also reached more than 10%.
So how to choose a template form is very important for cost control. Today, through cost analysis of several commonly used template forms, we will help everyone further understand the cost situation of templates and provide a basis for template selection.
The commonly used templates in the current market can be roughly divided into wooden templates, steel templates, aluminum templates, etc. based on the type of main material used; According to the different support systems, various forms such as wooden formwork and steel support composite formwork have emerged recently..
In the current construction template engineering, the application of wooden templates is still mainstream. However, the use of steel supports (complete sets of steel supports or steel square joints, etc.) instead of traditional wooden blocks as the main and secondary back ribs of the formwork reinforcement system has been increasingly favored by construction units, as this technology brings economic and social benefits.
Aluminum alloy formwork is an important technology for energy conservation and emission reduction in the construction industry, which can improve the construction efficiency and quality of housing construction. It has been widely promoted and applied in current construction projects.
Compared with steel formwork, aluminum alloy formwork has greater strength, is not afraid of water, and does not rust. At the same time, compared with bulky steel, aluminum alloy is much lighter in weight, which is conducive to the construction of construction projects. It is also particularly suitable for areas lacking labor sources and high labor costs.
The new assembled building formwork support system product belongs to the category of new building materials, which is one of the technologically advanced building formwork processes in China’s new building formwork support. It is also the first generation of new building formwork products in China..
The new prefabricated building formwork structure mainly consists of three parts: panels, support structures, and connectors..
The new modular formwork support system for building construction includes vertical wall support system, roof support system, and framework.
The three main parts of column support can meet different construction needs..
There are differences in various templates due to their own system structure, material types, and other characteristics. The main situation is shown in the table below:.
At present, templates in the cost system appear as a list of measurable measures. According to the pricing method of the list, the template price mainly consists of material costs, machinery costs, labor costs, and management fees, profits, regulations, taxes, etc. reported by the construction party. The material cost is an objective factor, and its level directly affects the cost of the template;.
Although the cost of machinery is influenced by factors such as location and time, the impact is not significant, and the pattern reflected in the actual quotation list is also the same;.
Management fees and profits are factors related to the construction enterprise, and the changes are related to the enterprise’s management ability and profit expectations, which may be significant. In order to facilitate analysis and unify the caliber, this part of the analysis will be unified;.
Fees and taxes belong to policy expenses and are considered according to unified standards..
Further analysis shows that the cost of template materials is mainly affected by factors such as raw material prices, consumption, acquisition forms (procurement, leasing), turnover times, and recyclable residual values..
Additionally, due to the use of different template systems, it is possible to obtain.
