Formwork support system is produced and developed with the requirements of building construction. It is an essential measure and equipment in construction operation.

Disadvantages of fastener type steel pipe support system:

Unsafe: the vertical pole and cross bar are connected by fasteners, and the vertical pole is connected by slotted fasteners, which has poor stability

Not environmentally friendly: the main keel is mostly 100 × 100 cubic meters of wood, with a large amount of wood input

High aging rate: it has been circulating in the market for many years, with serious corrosion, and the wall thickness is generally less than 3m

Low efficiency: Fasteners need to be disassembled in the process of erection and dismantling, and the erection and dismantling speed is slow

High loss: the connecting fastener is separated from the steel pipe, and the loss rate of fastener is high

Inflexible: the height of vertical pole is limited by the length of steel pipe in the market, and the combination of height modulus is inflexible

Advantages of bowl button steel pipe support system: the bowl button support is researched and designed by the professional design institute of the Ministry of Railways and passed the ministerial appraisal in 1984. It is a widely used support system in the construction industry for many years. The bracket is designed with toothed wrist buckle joint, which is not only quick and labor-saving, but also has simple structure, stable and reliable stress, avoids bolt operation, is not easy to lose scattered accessories, and is safe, convenient and economical.

Disadvantages: the bowl buckle frame is a tool scaffold, which has low technical requirements for workers and reduces the impact of human factors on the erection quality. However, due to the limitation of product modulus, its universality is poor, and the accessories are easy to be damaged and inconvenient to repair. Moreover, the bowl mouth frame in the market lacks special accessories such as supporting inclined rods, and most of them need to be combined with steel pipe fastener frame, which reduces its actual bearing capacity.

3. Portal steel pipe support system

Portal frame is widely used in southern China and decoration industry. The portal scaffold is a standard shaped component, which has the advantages of simple erection and operation, high work efficiency, small cross-section size and good economy. However, as a tool shaped product, it also has the problem of universality, and most of its upright rods are O42 0 steel pipe, and its special fasteners are in short supply in the market.

4. Turnbuckle steel pipe support system

Advantages of steel pipe support system with turnbuckle type:

1. The raw materials of the pole are upgraded, and the surface is hot-dip galvanized, with high bearing capacity:

2. The joint connection is reliable. The vertical rod and the horizontal rod are connected by the axis, and the supporting inclined rod connection improves the lateral force resistance stability of the frame body:

3. The serialized and standardized design of members can adapt to the assembly of various structures and spaces, and the collocation is flexible. Due to the connection of inclined rods, cantilever structures and span structures can also be set up:

4. Compared with other support systems, under the same load, the material can be saved by 13-1 / 2, and the service life of the product can reach 15 years.

5. Advantages of socket keyway steel pipe support socket keyway steel pipe support: designed according to the construction characteristics of high-rise reinforced concrete structure, it is a building formwork support system with simple operation, low cost, safety and reliability. It has no vulnerable parts and good durability. It can speed up the turnover of formwork, save investment, reduce labor cost and shorten the construction period.

6. Bench mold

Platform formwork, also known as flying formwork, is a large tool formwork for cast-in-situ reinforced concrete floor slab. Generally, there is one bench model in one room. The platform formwork is a large-scale tool type formwork composed of platform plate, beam, support, support and adjusting legs. It can be demoulded and transported as a whole, and can be transferred from the poured floor to the upper layer for reuse with the help of crane. It is applicable to the construction of cast-in-situ concrete floor with large bay and deep depth of high-rise buildings, as well as the construction of cast-in-situ beamless floor without column cap of cold storage, warehouse and other buildings. Due to its fast assembly and disassembly, labor-saving and low technical requirements, it has been popularized in many countries. The United States, Russia, Japan, France, Germany, Sweden and other countries have their own formwork system. It has also been applied in high-rise building construction in China, but it has been less applied in recent years. Applicable to beamless floor.

7. Ordinary independent steel support

Independent steel support is a kind of independent steel support composed of support column and support head, which is characterized by:

(1) Two groups of spaced limb angle steels are welded on the steel plate surface of the support head; Click here to download construction technical data for free

(2) The lower part of the support column is provided with a folding tripod composed of the support frame assembly head, the support, the left and right slips of the column and the locking device. The support frame assembly head is in a channel steel section, the web of the channel steel section is provided with a rectangular hole, the web is welded with a main support, the upper and lower flange plates are provided with pin holes, the left and right supports are connected with pins, and the left and right slips of the column are sleeved on the pin shafts of the left and right supports, The slip is welded by the upper and lower slips and slip plates: the locking device handle welded with fan-shaped steel plate is connected to the main support with a pin.

(3) The inner pipe supporting the column is sleeved with a return pin.

8. Aluminum alloy formwork

Aluminum template has been used for 50 years since it was born in the United States in 1962. It has been widely used in the buildings of developed countries such as the United States and Canada, as well as emerging industrial countries such as Mexico, Brazil, Malaysia, South Korea and India. Aluminum formwork has been developed in China for only a few years and has been favored by many builders. For example, Vanke and China Construction Group are using aluminum formwork system. The largest application builder of aluminum formwork is Vanke, one of the leaders in the real estate industry. Almost all high-rise buildings of Vanke are designated to adopt aluminum formwork system.

9. Tower

It is mostly used for steel structure installation and heavy load support, which is characterized by high bearing capacity and convenient combination. It is suitable for bearing concentrated load on point support. Tower is widely used, mainly for factory chimney support, large building support, water tower, monitoring engineering, communication engineering and other special purposes. Main structure and materials: three column steel pipe (flange connection) and four column angle steel (connecting plate).
