Problems solved by technology

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 re-punching will also affect the safety of the structure

Embodiment 1

[0025] Embodiment 1: A core-filling compensating backing plate with an adjustable alignment reserved hole misalignment. The compensating backing plate is made into two groups and used together. It includes a fixed plate 1 with a diameter larger than the reserved hole and a core tube 2 whose outer diameter is consistent with the diameter of the reserved hole. The core tube 2 is fixed on the center of one side of the fixed plate 1, and the core tube 2 is hollow. Tubular structure, a circular through hole 3 is provided in the area corresponding to the inner cavity of the core filling tube 2 on the fixing plate 1 .

[0026] Wherein the through hole 3 on the fixed plate 1 of one group is positioned at the center in the area corresponding to the inner chamber of the core pipe 2 on the fixed plate 1, and the edge of the through hole 3 on the other set of fixed plate 1 is in line with the center of the core pipe 2. Edges coincide.

[0027] The method of using the above-mentioned alig...

Embodiment 2

[0033] Embodiment 2: An adjustable core-filling compensation backing plate with alignment reserved holes and misalignment. The difference from Example 1 is that the through hole 3 of the fixing plate 1 is elliptical, and only one kind of compensation backing plate needs to be made. Specification.

[0034] The diameter of the elliptical through hole 3 on the fixed plate 1 is smaller than the aperture of the reserved hole, and one of the focal points of the elliptical through hole 3 is located at the center of the area corresponding to the inner cavity of the core tube 2 on the fixed plate 1, and the edge Coincides with the edge of the core tube 2.

[0035] When in use, insert the bolts into the holes of the compensation backing plate at one end, and rotate and adjust the compensation backing plate according to whether there is any error in the position of the reserved hole at the other end, so that the positions of the openings on the compensation backing plates at both ends co...

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 ...
