TECHNICAL FIELD

[0001] The application belongs to the field of templates, more particularly, to a steel template construction auxiliary equipment and construction method. BACKGROUND

[0002] The steel template construction auxiliary refers to the technical measures for supporting, positioning and forming by using the steel template system in the concrete pouring process. The steel template has the advantages of high strength, large rigidity, good durability, smooth concrete surface after demolding and the like, and is widely used in building, bridge, tunnel and the like engineering.

[0003] In the shallow water construction, the impurities in the water are difficult to be completely removed and are easily attached to the surface of the steel template. This not only affects the concrete forming quality due to uneven force on the side of the template, but also causes difficult-to-remove corrosion problems due to long-term attachment, which seriously affects the repeated use performance of the steel template and the durability of the engineering structure.

The net body and the connecting strip are connected with the soft strips on the left and right sides. When the net body and the connecting strip are dynamically changed in shape due to external force, the attached organisms fall off due to the reduction of contact area. The sliding block limits the range of the whole up and down movement. The fixed column is an I-shaped structure.

[0013] As a further improvement of the application, the steel formwork construction auxiliary equipment has the following steel formwork construction auxiliary method:

[0014] S1: when the steel formwork is used in shallow water, the two semicircular movable nets are fixed and combined through the magnetic attraction strip, the rubber base is fixed on the pre-levelling base through the mechanical engagement of the clamping block and the reserved clamping groove of the steel formwork, the water is squeezed into the water isolation area through the suction port, the negative pressure sealing is formed to further absorb the base, and the water in the water isolation area and the inner formwork is pumped out through the water pumping equipment when the outer formwork and the inner formwork adopt the telescopic expansion structure and are adjusted to the required height, so as to ensure that the rubber base and the base form a watertight connection, and after the sealing property is qualified, the concrete is poured into the inner formwork, and the water isolation area serves as a secondary anti-seepage barrier to protect the formed surface.

[0015] S2: when the outer formwork and the inner formwork adopt the telescopic expansion structure and are adjusted to the required height, the water in the water isolation area and the inner formwork is pumped out through the water pumping equipment, so as to ensure that the rubber base and the base form a watertight connection, and after the sealing property is qualified, the concrete is poured into the inner formwork, and the water isolation area serves as a secondary anti-seepage barrier to protect the formed surface.

[0016] S3: The floating body drives the slider to vertically displace along the limiting body with the water level change, drives the net body to form a dynamic interception surface, and under the action of the water level power of the floating body, the attachment area of the net body and the contact object is continuously shaken and changed, which assists in further detaching, and the shaking of the water body can simultaneously push the extension body to assist, drive the whole to rotate along the slide, and further rotate to detach the attached substances;

This design effectively prevents aquatic organisms and impurities from attaching to the surface of the steel formwork, avoids corrosion and wear, and at the same time enhances the structural stability of the concrete during molding. At the same time, the dynamic movement characteristics of the net body can actively detach the attached substances during the interception process, thereby significantly improving the long-term durability and construction quality of the steel formwork.

[0021] 2. The steel formwork is stably installed with the base through vacuum adsorption formed by the rubber base and the adsorption port. During the concrete molding process, the water in the water separation area and the inner template is quickly pumped out by the pumping equipment, which not only ensures the construction efficiency, but also effectively blocks the penetration of external water through the double waterproof structure, providing double protection for the concrete, significantly improving the molding quality and structural durability. This design not only ensures the stability of construction, but also fundamentally solves the leakage problem during underwater pouring.

[0022] 3. The active net adopts a two-semicircle combined design, which is convenient for quick disassembly and maintenance. This structure allows the net body to be directly washed after disassembly, effectively removing the intercepted attachments and completely protecting the surface of the steel formwork from biological attachment and erosion. Not only does this design greatly improve the maintenance efficiency, but also ensures that the interception system remains in the best working condition for a long time, thereby prolonging the service life of the steel formwork.
