A core-filled compensating backing plate and its use method which can be adjusted for misalignment of reserved holes for alignment

Abstract

The invention discloses core filling type compensation backing plates capable of adjusting misalignment of alignment reserved holes. The core filling type compensation backing plates comprise fixing plates and core filling pipes, wherein the diameters of the fixing plates are greater than the hole diameters of the reserved holes; the outer diameters of the core filling pipes are consistent with the hole diameters of the reserved holes; each of the core filling pipes is fixed at the center of one surface of the corresponding fixing plate; the core filling pipes are of hollow tubular structures;and circular or oval through holes are formed in the areas, corresponding to the inner cavities of the core filling pipes, of the fixing plates. According to the core filling type compensation backing plates capable of adjusting the misalignment of the alignment reserved holes, the reserved holes of which the hole diameters are slightly greater than a set hole diameter are reserved in to-be-perforated positions of a structure; the compensation backing plates are inserted into the reserved holes; and the through holes capable of adjusting the direction and position are formed in the compensation backing plates, so that the alignment of the reserved holes at two sides can be ensured. In addition, the compensation backing plates are of truncated cone structures with stepped surfaces so as toachieve stable force bearing of an entire alignment system and avoid the influence on the fixing effect of the alignment system while ensuring that the diameters of the open holes are greater than the set hole diameter.

Description

technical field

[0001] The invention belongs to the field of building construction, and in particular relates to an alignment fastening method for reserved construction holes. Background technique

[0002] In building construction, it is often necessary to reserve alignment holes in the structure for passing fasteners such as screw bolts and fixing other devices. However, in actual construction, it is difficult to completely avoid the misalignment of the reserved holes at both ends of the structure. If the error is large, the original reserved holes must be sealed and opened again after the position is found. However, the impact of this method on the structure is Obviously, not only the reserved holes in the back seal cannot meet the structural standards, but also the re-punching will affect the safety of the structure.

[0003] In addition, even if the error is small, although it is within the allowable range in the building construction standard, it also has an impact on ...
