Problems solved by technology

At present, post-anchoring methods mainly include expansion bolts and chemical anchor bolts. These two anchor bolts are flexible and widely used, but the bearing capacity of the expansion bolts is low, especially in the case of bearing axial tension, and the effect is even worse; Anchor bolts are not resistant to high temperature welding, not suitable for pouring on the ceiling, and have limited service life and many other shortcomings
limit their use
The national standard "Technical Specifications for Post-anchoring of Concrete Structures" JGJ145-2013 has made strict restrictions on the use of expansion bolts and chemical anchors in lifeline engineering. A safe and reliable post-anchoring method in lifeline engineering is still lacking.

Abstract

The invention relates to a thread-connection post-anchoring construction method. The method comprises the steps that firstly, a hole is drilled in the designated position of a concrete, building stone and ceramic material base body through a water drill, wherein the diameter and depth of the hole correspond to a selected standard bolt and a metal screw core in specification; secondly, an internal screw milling machine spindle is inserted into the hole, large-pitch trapezoid threads are machined on the smooth inner hole; thirdly, a metal screw core matched with the trapezoid threads is screwed in the trapezoid thread hole through an inner hexagonal or linear spanner, and standard threads are machined on an inner hole of the metal screw core; fourthly, one end of the standard bolt is connected to the metal screw core, the other end of the standard bolt is connected with a connected object, the connected object is fixed to the base body, and a grouting material is used for grouting after installation on the occasion that disassembly is not needed. The large-pitch trapezoid thread metal screw core is used as post-anchoring parts to be installed inside the concrete, building stone and ceramic material base body, the external standard bolt is used as a connecting part, the fixed object is firmly fixed to the base body, and therefore the anchoring effect is achieved.

Description

technical field [0001] The invention relates to the technical field of post-anchor, in particular to the technical field of post-anchor in the building installation industry. It is a new post-anchor technology for threaded connection and fixation on concrete, rock, and porcelain materials. It mainly includes processing internal thread equipment and related construction methods. Background technique [0002] In the process of modernization construction, a large number of concrete and natural stone materials have been used, and most of the industrial equipment foundations, plant beams and columns are reinforced concrete structures. Especially in the urbanization construction, high-rise buildings with reinforced concrete have sprung up, stone walls and stone pillars can be seen everywhere, and dry-hanging stone curtain walls have gradually replaced wet-pasted stone curtain walls. It is a problem that people encounter all the time in order to have a stable connection (post-anch...
