Description

Technical Field

[0001] The utility model belongs to the technical field of manual dug pile construction, and particularly relates to a fixed steel formwork structure facilitating the installation and disassembly of manual dug piles. Background Technique

[0002] A manual dug pile is a reinforced concrete pile formed by manual digging. Given its relatively large construction depth, the stability of the retaining wall becomes a key link in the construction process. For the installation and disassembly of traditional reinforced concrete retaining wall formwork, wooden formwork is usually adopted, supplemented by the fastening method of steel pipes and wooden squares. In this construction method, a steel pipe bracing system needs to be set up in the hole first, which not only reduces the construction efficiency, but also causes the trouble of lacking an operation platform during concrete pouring due to the existence of the steel pipe bracing. In addition, considering the reuse of the formwork, the phenomena of formwork displacement and slurry leakage become increasingly prominent with the increase in the number of times the formwork is used. These factors all pose certain challenges to the project quality and construction safety. Content of the Utility Model

Adjacent formworks are symmetrically and staggeredly arranged. An adjustable bolt for adjusting the length of the member is arranged on the rod to control the fastening degree of the formwork. The fastening bolts connect the vertical back ribs of adjacent formworks, and the splicing seam of the formwork is controlled by adjusting the fastening degree of the bolts.

[0007] The horizontal back rib is fixedly connected to the lower surface of the back side edge of the steel formwork by welding. The horizontal back ribs of adjacent formworks are staggeredly arranged. Both the horizontal back rib and the vertical back rib are made of 4cm*4cm square steel.

[0008] The adjustable strut member is made of 4 cm * 4 cm solid square steel. One end is drilled with holes for easy connection of the bolt assembly, and the other end is processed into a threaded shape within a range of 5 cm to connect the adjustable bolt.

[0009] The support bracket is made of threaded steel bars with a diameter of 28 mm and a length of 5 cm, and is directly welded to the surface of the steel formwork; the nut of the bolt assembly is directly welded to the back rib.
