Description

Architectural composite modular formwork

Technical field

The invention relates to the field of building technology, in particular to a building composite modular formwork.

Background technique

The building formwork is a temporary supporting structure, which is made according to the design requirements, so that the concrete structure and members are shaped according to the specified position and geometrical dimensions, maintaining their correct position, and bearing the self-weight of the building formwork and the external load acting on it. The purpose of the formwork project is to ensure the quality of concrete works and construction safety, speed up construction progress and reduce engineering costs.

The building formwork structure used for the construction of cast-in-place concrete structures is mainly composed of three parts: panel, support structure and connecting parts. The panel is a bearing plate directly contacting the newly poured concrete; the supporting structure is a temporary structure supporting the panel, the concrete and the construction load, ensuring that the building formwork structure is firmly combined so as not to be deformed or damaged; the connecting piece is the panel and the supporting The structure is connected into an integral fitting.

The building formwork is a formwork and bracket for concrete pouring. According to the nature of the material, it can be divided into building wood board, bamboo board, laminated board, wooden wood square, steel square steel, steel combination formwork, aluminum combination formwork, Injection molding combination template, etc. According to the construction process conditions, the building formwork can be divided into cast-in-place concrete formwork, pre-assembled formwork, large formwork, jump formwork and so on.

The combined steel formwork is a traditional template of “making steel to replace wood” with the advantages of high versatility and many turnover times in the modern formwork technology. It can be used for the construction of cast-in-place reinforced concrete structures, which can be set according to the design requirements in advance. Large-scale formwork for beams, columns, walls, and slabs. The whole hoisting is in place, and bulk disassembly methods can also be used. Disadvantages are bulky, many models, complicated combination, non-cutting, deformation is not easy to repair, the surface needs to be coated with release agent during construction, the gap between the assembly is easy to leak the paddle to affect the quality of the concrete, and the appearance of the component after repeated use is not good.

With the fierceness of China's real estate industry and the continuous construction of various projects, the formwork industry has developed rapidly. In 2009, the use of building formwork reached 585 million square meters, a year-on-year growth rate of 7.3%. The industry expects that in 2010, under the support of favorable policies for domestic investment and the gradual improvement of the international economic environment, the production scale of China's building formwork industry will maintain a growth rate of around 10%; China's construction from 2011 to 2012 The average annual production scale growth rate of the formwork industry will be around 15%; by the end of 2013, the output of China's building formwork industry has reached 220 million square meters.

In the early 1970s, China’s building structure was dominated by brick-concrete structures, and the building construction template was thickened. Wood template is the main one. In the early 1980s, various new structural systems continued to emerge, and cast-in-place concrete structures soared. Due to the very poor timber resources in our country, China has successfully developed the advanced construction technology of combined steel formwork under the principle of “taking steel to replace wood”, reforming the formwork construction process, saving a lot of wood, and the steel formwork application area has reached 75%. Above, the steel formwork production plant has reached more than 1,000, the steel formwork leasing company has reached more than 13,000, and the annual savings of substitute wood is about 15 million cubic meters, which has achieved significant economic and social effects. Since the 1990s, China's building structure system has developed greatly. High-rise buildings, super high-rise buildings and large public buildings have been built in large numbers. Large-scale infrastructure construction, urban transportation, highways, railways, etc. have developed rapidly. The scaffolding construction technology has put forward new requirements. China has continuously introduced foreign advanced formwork systems, and has also developed a variety of new templates and scaffolding. At present, the pattern of combined steel formwork in China has been broken, and has gradually changed into a pattern of multiple templates coexisting. The application of combined steel formwork is declining, and the development of new formwork is fast.

Before 2004, China's construction was dominated by steel formwork. The shortcomings of this type of formwork were cumbersome, complicated in specifications and models, easy to deform, easy to leak, inconvenient to operate, time-consuming and labor-intensive, and the appearance of components was not good. After 2005, steel formwork It is replaced by wood glued formwork and square wood. When the formwork is used for construction, the external dimensions of the cast-in-place concrete members are generally firstly cut and matched, and then transported to the construction site for assembly according to the size. The nails, iron wire and pull screw are used for preliminary analysis. Stereotype, nail the square wood to the wooden mold, and finally use the steel pipe support system to strengthen, the wood formwork system is easy to damage when it is removed, the theoretical use turnover rate is 3-6 times, and the operation can only reach 1 in the individual component parts. -3 times (according to China Statistics 2013), the construction area in 2012 reached 11.65 billion square meters, and the consumption of wood was about 120 million cubic meters. Such a wooden formwork has low turnover rate, high loss, high cost, complicated construction, waste of time, waste of labor, low recycling, serious pollution after ignition and heat, increased smog and harmful gases, and increased deforestation. Not sustainable.

The traditional formwork generally first cuts and fits the outer dimensions of the cast-in-place concrete members, and then carries them to the construction site for assembly according to the size. The nails, the iron wires and the pull-up screws are preliminarily shaped, and the square nails are nailed by the nails. On the wooden mold, the steel pipe support system is finally used for reinforcement. When the wood formwork system is removed, the wooden side is removed again from the root. This repeats the labor and wastes the nails and other materials, and is easily damaged. The theoretical use turnover rate is 5-6. The operation time can only reach 1-3 times in individual component parts. Such a building template has low turnover rate, high loss, high cost, complicated construction, wasted time and is not environmentally friendly, and the template is easily broken when used and removed. There is a need to find a way to solve this problem.

Summary of the invention

In view of the above situation, in order to overcome the defects of the prior art, the object of the present invention is to provide a composite composite formwork for building, which effectively solves the traditional high energy consumption of template production, cumbersome processing, easy to use, and low turnover rate of building templates. Problems such as high loss, high cost, complicated construction, wasted time and no environmental protection.

The technical solution for solving the problem comprises: comprising a rectangular template, at least two main ribs are arranged under the rectangular template, a plurality of connecting ribs are connected between each two main ribs, and reinforcing blocks are arranged at four corners below the rectangular template.
