AI Technical Summary
The embedded part brackets of traditional hydraulic climbing formwork are prone to loosening during up-and-down movement, affecting structural stability.
The positioning assembly, which combines a pre-embedded seat, fastening bolts, and positioning pins, forms a self-locking structure by creating clearance grooves, bolt holes, and locking tooth grooves on the pre-embedded seat and installing movable seats and engaging teeth on the fastening bolts. Combined with the adsorption effect of neodymium iron boron magnets and ferromagnetic materials, it ensures positioning stability.
This effectively prevents the positioning components from loosening, improves the positioning stability of the embedded part bracket, and facilitates the overall disassembly and assembly of the structure and the safety of the lifting process.

Description
Technical Field
[0001] This invention relates to the technical field of hydraulic climbing formwork, specifically to an inverted V-shaped tower column hydraulic climbing formwork mechanism and its construction control method. Background Technology
[0002] Hydraulic climbing formwork is short for hydraulic climbing formwork. It is a new process that combines slip formwork and support formwork. It absorbs the advantages of support formwork, such as pouring concrete in the conventional way, which is simple in labor organization and construction management, less restricted by external conditions, and easy to ensure the quality of concrete surface. It also avoids the common defects of slip formwork construction, and construction deviations can be eliminated layer by layer.
[0003] In terms of climbing method, it is the same as the slipform process. The lifting frame, template, operating platform and hanger are raised by hydraulic jacks. There is no need for repeated assembly and disassembly of tower crane, nor is it necessary to lay out lines layer by layer and erect scaffolding. The steel bars are tied as they are raised, and the operation method is safe.
[0004] The connection between the hydraulic climbing formwork and the wall is fixed by embedded brackets. However, traditional embedded brackets are fixed by bolts. When the hydraulic climbing formwork moves up and down, it will generate a certain degree of mechanical vibration, which can easily cause the installation structure of the embedded brackets to loosen, thus affecting the overall stability of the structure. To address this problem, this invention proposes an inverted V-shaped tower column hydraulic climbing formwork mechanism and its construction control method. Summary of the Invention
[0005] The purpose of this invention is to provide an inverted V-shaped tower column hydraulic climbing formwork mechanism and its construction control method to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic climbing formwork mechanism for an inverted V-shaped tower column, comprising a climbing formwork mechanism body and an embedded part bracket for positioning the climbing formwork mechanism body, wherein the embedded part bracket is fixed to the building wall by a positioning component, the climbing formwork mechanism body includes a guide rail, a climbing formwork frame, a hydraulic cylinder, a reversing box, and a climbing cone, and the positioning component includes:
[0007] An embedded seat is cast and embedded in the building wall, and a clearance groove is provided on the embedded seat. Bolt holes are provided at the bottom of the clearance groove, and a toothed groove is provided on the side wall of the clearance groove.
[0008] The fastening bolt is composed of a nut, a retaining tooth seat and a screw rod. The nut, retaining tooth seat and screw rod are provided with mounting grooves. The mounting groove is provided with a movable groove on the side wall of the retaining tooth seat. A movable seat is movably installed in the movable groove. The outer end of the movable seat is integrally formed with engagement teeth.
[0009] The positioning pin is inserted into the mounting groove, and the inner end of the movable seat is limited by the positioning pin.
[0010] Preferably, the nut, the retaining tooth seat, and the screw are integrally formed, the inner end face of the movable seat is arc-shaped, and the arc value of the inner side of the movable seat matches the arc value of the outer side wall of the positioning pin.
[0011] Preferably, the positioning pin is a neodymium iron boron magnet rod, the movable seat is cast from ferromagnetic material, the embedded seat and fastening bolt are cast from non-ferromagnetic material, and the front end of the positioning pin is integrally formed with a tapered head, and the material of the tapered head is the same as that of the positioning pin.

[0013] Preferably, the movable groove is provided with a circle around its circumference, and a movable seat is movably installed in each movable groove. When the positioning pin is actually installed, its engaging teeth protrude on the outside of the movable groove, and at this time, the engaging teeth are embedded in the tooth groove. The inner end of the movable seat is cut at the corner of the side facing the nut to form a chamfer.
[0014] Preferably, the mounting groove is provided with an annular groove, an insertion groove and a limiting groove on the side wall of the nut part. The insertion groove and the limiting groove are symmetrically arranged in a set, and the insertion groove and the limiting groove are arranged in a cross shape.

[0015] Preferably, a support spring is provided at the bottom of the mounting groove, and a limiting protrusion is integrally formed on the side wall of the positioning pin. A set of limiting protrusions is symmetrically arranged, and the size of the limiting protrusion matches the size of the limiting groove. When the limiting protrusion is embedded in the limiting groove, its conical head abuts against the support spring, and at this time, the support spring is under pressure.
[0016] Preferably, a pull handle is fixedly welded to the end of the positioning pin, the pull handle is arranged in the same direction as the limiting protrusion, and the edge of the limiting protrusion facing the pull handle is chamfered.
