Composition of individual steel supports

The inner pipe is made of φ48mm welded steel pipe (wall thickness between 2.5-3.0), the inner pipe has a pin hole at every 100mm interval, which can be inserted into the shaped steel pin, φ60mm steel pipe (wall thickness between 2.5-3.0), and the outer pipe is welded with a threaded pipe, which is made of seamless steel pipe and matched with micro-nuts. Fine tuning range 1-100mm. Adjustable height range of independent support is 1.9m--4.5m Note: 2.75 wall thickness of the single root load is 3.68 tons in the use of engineering, with tripod use

Use method and scope of independent adjustable steel support

Independent support is a kind of formwork support commonly used in early demolishing construction technology of building engineering.

The advantages of independent support are:

1. Wide range of applications: independent support can be used with primary and secondary beams and bamboo and wood plywood or plastic formwork to form early release formwork system, independent support can be used with steel frame plywood formwork to form table mold system, independent support can be used with aluminum alloy formwork and combined ribbed plastic formwork, respectively, to form aluminum alloy formwork system and combined ribbed plastic formwork system. The independent support in the early demolition mold system is not restricted by the fixed plane size, and the support spacing and the primary and secondary beam spacing can be adjusted in time according to the beam and plate load, which can be widely used in regular or irregular building planes.

2. Convenient application: the independent support can be adjusted the length and size, and can be fine-tuned, there is no fixed horizontal link between each other, the independent support is equipped with the corresponding support head with the primary and secondary beams, steel and aluminum frame templates, aluminum alloy templates, plastic templates, etc., easy to install and remove.

3. Safe and reliable: the independent support is used in the vertical state to bear the weight of the horizontal structure of the building, the body weight of the formwork system and the construction load. In addition to the temporary stable connection or the tripod for reinforcement, the square bracket is equipped with no fixed horizontal connection rod, which is stable and reliable. The independent support is used as the template and the diagonal brace to keep the vertical structure template stable.

4. Fast construction speed: the structure of the independent support system is simple, the amount of steel is less, therefore, the amount of labor should be reduced, and the labor rate is high. In tower residential buildings, for example, 600-800 square meters of mold area per floor takes only half a day, only one-half to one-third of the time of other support systems.

5. Save a lot of steel: under the same die area conditions, the independent support is less than the bowl type die support frame, and the steel pipe fasteners die support frame consumes less steel, about 30% of the bowl buckle frame or steel pipe frame.

6. Reduce construction costs: Due to the reduction of the horizontal formwork and support system input, but also to achieve early removal of the beam plate formwork, accelerate the turnover of the formwork and support system, at the same time, save a lot of labor costs, so can significantly reduce construction costs.

7. The construction site is civilized and unobstructed: the independently supported construction site has fewer vertical poles and no horizontal poles, so that personnel can pass, materials can be handled smoothly, and the site is civilized and clean.

8. Reduced vertical transport: Independent support can be manually transported from the stairwell, can also be concentrated on the unloading platform, vertical transport by the tower crane, due to the small amount of steel used for independent support, so the vertical transport is significantly reduced.

Due to these advantages of independent support, attention by construction units, but also favored by manufacturers, in addition to some manufacturers accept orders for processing exports, the domestic production of independent support manufacturers gradually increased, especially in recent years, as aluminum alloy formwork and combined ribbed plastic formwork supporting system and early removal template construction technology promotion and application, The development of independent steel support faster, at the same time, independent aluminum support has also begun to produce and export, economic benefits are obvious, with the national energy saving and emission reduction, green construction policy implementation, traditional steel pipe fasteners and other traditional die will be gradually phased out, the new template support system will be promoted and applied.

Use method and scope of independent adjustable steel support

1. Rotate the adjustment nut to the lowest position using the handle.

2. Insert the upper tube into the lower tube to the desired height, and then insert the pin into the adjustment hole above the adjustment nut.

3. Move the adjustable steel supporting top to the working position and rotate the adjusting nut with the handle to make the adjusting supporting top fix the supported object. It can be fixed by tripod.
