Abstract
The invention relates to a method for solving an over-low problem of an embedded bolt in a mantle fiber diameter enlarging method, which comprises the following steps of: (1) screwing a first nut to outer threads of the embedded bolt and fastening to the bottoms of the threads, wherein the diameter of the first unit is greater than that of the embedded bolt; (2) screwing a screw rod to the embedded bolt through inner threads of the first unit and fastening in place through a second nut; and (3) screwing off the first nut, installing adjusted equipment and then sequentially fastening the two nuts in place, wherein the first nut and the second nut have same diameters. The invention has the advantages that in the method, the integrity of the original embedded bolt is reserved so that the embedded bolt has high binding strength and attractive appearance; and the method cannot destroy the strength of original concrete and has short processing time without influencing a construction period.
Description
Technical field:
The invention belongs to a kind of construction techniques, particularly a kind of mantle fiber becomes the major diameter method and solves the method that pre-embedded bolt is crossed low phenomenon.
Background technology:
Can run into the low excessively phenomenon of basic pre-embedded bolt in many installing engineerings, Installation unit is met all difficult solution of this type of problem, the employing butt welding extension bolt method that has, and the method has been destroyed the globality of pre-embedded bolt, does not reach bond strength and not attractive in appearance; And the method also will destroy original concrete strength, and the processing time is very long, and will be bigger to the duration influence.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art, solves the method that pre-embedded bolt is crossed low phenomenon and provide a kind of mantle fiber to become the major diameter method, and this method is simple to operate, and can solve the low excessively phenomenon of pre-embedded bolt effectively.
Technical scheme of the present invention is: a kind of mantle fiber becomes the major diameter method and solves the method that pre-embedded bolt is crossed low phenomenon, it is characterized in that: carry out according to the following step: (1) is screwed to a diameter on the external screw thread of pre-embedded bolt and is fastened to the bottom of thread greater than first nut of pre-embedded bolt; (2) internal thread by first nut is screwed to screw rod on the pre-embedded bolt, and by second fastening putting in place of nut; (3) back out first nut, install and adjust equipment, again with two fastening successively putting in place of nut; Above-mentioned first nut is identical with the diameter of second nut.
Advantage of the present invention is: the method keeps the globality of former pre-embedded bolt, and bond strength is big and attractive in appearance; And the method can not destroy original concrete strength, and the processing time is short, can not influence the duration.
Description of drawings:
Fig. 1 is a schematic diagram of the present invention.
The specific embodiment:
As shown in the figure: with M30 (1) pre-embedded bolt is the utilization that example explanation mantle fiber becomes the major diameter method: 1, earlier a M48 (2) nut is screwed on the external screw thread of pre-embedded bolt and is fastened to the bottom of thread.2, the internal thread (3) by first nut is screwed to screw rod (4) on the pre-embedded bolt, and by second fastening putting in place of nut; 3, back out first M48 nut, install and adjust equipment, again with two fastening successively putting in place of M48 nut.
Among the figure: L1---2.5 times of M30 nut thickness;
L2---2.5 times of M48 nut thickness.
Claims (1)
1. a mantle fiber becomes the major diameter method and solves the method that pre-embedded bolt is crossed low phenomenon, it is characterized in that: carry out according to the following step: (1) is screwed to a diameter on the external screw thread of pre-embedded bolt and is fastened to the bottom of thread greater than first nut of pre-embedded bolt; (2) internal thread by first nut is screwed to screw rod on the pre-embedded bolt, and by second fastening putting in place of nut; (3) back out first nut, install and adjust equipment, again with two fastening successively putting in place of nut; Above-mentioned first nut is identical with the diameter of second nut.
