Embodiment 1

[0040] Such as Figure 1-3 As shown, the present invention discloses a device for repairing bolts of embedded parts. The broken bolts of embedded parts include broken upper section 1 and lower section 2 of bolts. The device for repairing bolts of embedded parts includes connecting sleeve 3, welding layer 4 and pour Layer 5.

[0041] Wherein, a first hole is provided at the concrete surrounding the bolt of the embedded part. In order to facilitate opening of the first hole, the concrete can be taken out to form the first hole after drilling around the bolt of the embedded part through a core drill. The outer diameter of the first hole is greater than the outer diameter of the connecting sleeve 3, the length of the first hole is greater than the length of the connecting sleeve 3, and the length of the first hole is greater than the length of the embedded part bolt embedded in the concrete, so that the embedded Pieces of bolts are dug out. The connecting sleeve 3 can be arrange...

Embodiment 2

[0046] In the second embodiment provided by the present invention, the structure of the embedded part bolt repairing device in this embodiment is similar to that of the embedded part bolt repairing device in the first embodiment. the difference.

[0047] In this embodiment, it is specifically disclosed that the inner hole of the connecting sleeve 3 is a tapered hole 301, and the diameter of the bottom end of the tapered hole 301 is smaller than the diameter of the top of the tapered hole 301, that is, the opening of the tapered hole 301 is large, and the bottom Small, easy to weld evenly. The outside of the connecting sleeve 3 is a cylinder, and the inside is in an inverted cone shape, which is a hollow one-piece metal tapered sleeve. The size of the metal tapered sleeve is determined according to the size of the bolts of the embedded parts and the surrounding installation space, and a welding space is reserved at the bottom of the inner side.

[0048] In order to achieve th...

Embodiment 3

[0054] Such as Figure 4 As shown, the present invention provides a method for repairing embedded part bolts, using the embedded part bolt repairing device in any one of the above embodiments, including the following steps:

[0055] Step S1: Open a first hole around the broken bolt of the embedded part, and take out the upper section 1 of the bolt and the lower section 2 of the bolt.

[0056] The concrete outside the bolt of the embedded part is drilled with a hollow drill, and the surrounding concrete is taken out, and the space around the bolt of the embedded part is taken out to form the first hole.

[0057] Step S2: Set the lower section of the bolt 2 into the connecting sleeve 3, set the connecting sleeve 3 into the first hole, and the bottom end of the connecting sleeve 3 is a preset distance from the bottom end of the first hole.

[0058] When the bolt lower section 2 is set in the connecting sleeve 3, the bottom end of the bolt lower section 2 can expose the connectin...

Abstract

The invention discloses an embedded bolt repair device and method. The embedded bolt repair device comprises a connecting sleeve, a weld layer and a pouring layer. A first hole is formed in the position, around an embedded bolt, of concrete. The outer diameter of the first hole is greater than that of the connecting sleeve. The length of the first hole is greater than that of the embedded bolt embedded in the concrete. The connecting sleeve can be arranged in the first hole. The bottom end of the connecting sleeve is a preset distance away from the bottom end of the first hole. The lower section of the bolt can be sleeved with the connecting sleeve and is welded to the connecting sleeve. The upper section of the bolt and the lower section of the bolt are aligned. The weld layer can wrap and fix the part, located in the connecting sleeve, of the upper section of the bolt and the part, located in the connecting sleeve, of the lower section of the bolt. The outer end of the weld layer is connected with the inner wall of the connecting sleeve. The first hole is filled with the pouring layer which wraps the connecting sleeve. By means of the embedded bolt repair device and method, the situation that a total foundation is excavated for treatment of the embedded bolt; online welding is conducted on a broken embedded bolt, and the influence on normal production of a coke oven is avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a repairing device and a repairing method for embedded part bolts. Background technique [0002] At present, most coke oven quenching line tracks are designed with concrete foundations without sleepers, and all embedded bolts on the track pressure plates are fixed on the foundation skeleton steel bars first, and then concrete is poured. Because the track has been rolled back and forth by the coke carrier vehicle for a long time, the bolts of the embedded parts on the pressure plate are broken, resulting in a larger gauge of the track, which cannot meet the operation of the coke carrier vehicle. In order to solve the above problems, the whole foundation is excavated to deal with the bolts of the embedded parts, which will lead to the shutdown of the coke oven, the interruption of the raw material supply of the blast furnace, and affect the normal production of the co...
