Description
Technical field
The present invention relates to the replacing construction method of pot bearing, in particular to a kind of benzvalene form branch for retaining whole anchor bolts
Seat changes construction method.
Background technology
At present, pot bearing changes technology largely using anchor bolt is all cut off in the prior art, and entirety is taken out
Old bearing, new bearing is integrally placed at former bearing, upper steel plate using being welded with the pre-buried leveling steel plate in beam bottom, adopt by lower steel basin
Clogged with epoxy resin mortar, or bridge, without beam bottom pre-embedded steel slab, lower steel plate is come using filling epoxy resin mortar on pot bearing
Ensure the mode that pot bearing is connected with beam bottom and pinner.
The construction technology has following disadvantage：
(1) in new pot bearing upper steel plate and the pre-buried leveling steel plate welding process in beam bottom, excessive temperature is easily to new benzvalene form branch
The function of seat tetrafluoro plate causes damage, and causes intensity to decline beam body concrete；
(2) after the leveling steel plate welding pre-buried with beam bottom of new pot bearing upper steel plate, new pot bearing will not have replaceable
Property；
(3) such as lower steel plate is attached with beam bottom and pinner by the way of epoxy resin is filled on pot bearing, is easily gone out
Now operate it is bad cause new pot bearing to bias, occur disease again；
(4) pot bearing is arranged at the larger continuous beam of across footpath, and continuous beam is affected by temperature, and can produce larger temperature
Vertically and horizontally stretch, once pot bearing can not meet vertically and horizontally stretching for continuous beam, by pot bearing and beam body and pinner
Connection produces larger horizontal force, and the tensile strength of epoxy resin is not high, is easily caused pot bearing and beam body and the company of pinner
Pick out existing disengaging to destroy, ultimately result in pot bearing failure.
The content of the invention
It is an object of the invention to provide a kind of pot bearing for retaining whole anchor bolts to change construction method, the construction party
Method remains whole anchor bolts of former pot bearing, and ensures that new pot bearing is connected reliably with beam body and pinner.
What this purpose of the present invention was achieved through the following technical solutions：A kind of benzvalene form branch for retaining whole anchor bolts
Seat changes construction method, it is characterised in that the construction method comprises the following steps：
The first step：Old pot bearing is handled；
Second step：Beam body uses synchronous jacking system, and top lifting height is more than the thickness of lower steel plate；
3rd step：Take out old pot bearing；
4th step：The processing of anchor bolt；
5th step：New pot bearing processing, new pot bearing is identical with the old pot bearing structure before processing, newly
Pot bearing installation before handled；
6th step：New pot bearing is installed；
7th step：Synchronization of jacking up jack oil return pressure release, pot bearing are changed and finished.
In the present invention, the first step：Old pot bearing is handled, concrete processing procedure is as follows：
(11), the lower steel plate anchor bolt nut of old pot bearing is removed, the lower steel plate anchor bolt includes later half
Part lower steel plate anchor bolt and first half lower steel plate anchor bolt；
(12), pot bearing is divided into first half and latter half, first half lower steel plate anchor with vertical removing direction
The upper surface flush of fixing bolt and lower steel plate cuts off；
(13) latter half lower steel plate, is processed into anchor bolt hole and cuts into U-type groove.
In the present invention, the 3rd step：Old pot bearing is taken out, concrete processing procedure is as follows：
(31), the lower steel basin of old pot bearing is prized to high, padding steel plate under lower steel basin, padding steel plate the top padding four
Fluorine plate, it need to ensure that the lower edge of lower steel plate is higher than the top surface of first half lower steel plate anchor bolt；
(32), force pulls out lower steel basin；
(33) upper steel plate anchor bolt nut, is screwed out, upper steel plate is taken out by external force, the upper steel plate anchor bolt includes
Latter half upper steel plate anchor bolt and first half upper steel plate anchor bolt.
In the present invention, the 4th step：The processing of anchor bolt, the anchor bolt include latter half lower steel plate anchoring spiral shell
Bolt, latter half upper steel plate anchor bolt, first half upper steel plate anchor bolt and first half lower steel plate anchor bolt, specifically
Processing procedure is as follows：
(41), latter half lower steel plate anchor bolt is in old pot bearing cutting latter half lower steel plate processing anchor bolt
Hole (13) is easily injured when forming U-type groove, the bolt thread need to be processed, it is ensured that its screw thread and nut phase
Matching；
(42), working process first half lower steel plate anchor bolt screw thread, and by first half lower steel plate anchor bolt
The tapped anchor bolt connection of first half lower steel plate anchor bolt hole size preprocessing of size and new pot bearing
Groove.
In the present invention, in the 5th step, handled before the installation of new pot bearing, concrete processing procedure is as follows：
(51) the latter half lower steel plate of new pot bearing, is processed into anchor bolt hole and cuts into U-type groove；
(52), the U-type groove cut into according to the latter half lower steel plate processing anchor bolt hole of new pot bearing is processed
Same material uniform thickness and the bloom to match with the U-type groove, bloom beat groove with lower steel basin contact portion.
In the present invention, the 6th step：New pot bearing is installed, concrete processing procedure is as follows：
(61), the upper steel plate of new pot bearing is separated with lower steel basin, carries out the fixation and protection of lower steel basin, installation is simultaneously
Upper steel plate is fixed with nut；
(62), the lower steel basin of new pot bearing is pacified according to the inverse process of the lower steel basin with taking out old pot bearing
Dress, the lower steel basin of new pot bearing is installed in place；
(63), the latter half lower steel plate processing anchor bolt hole of new pot bearing has been welded with the bloom matched
It is good；
(64) the anchor bolt nut of new pot bearing, is screwed.
The pot bearing of the present invention change when construction method solves existing replacing pot bearing pot bearing and beam bottom and
Pinner anchoring effect is poor, causes the use function of new pot bearing to be affected during the new pot bearing of installation, newly installs
The problem of pot bearing later stage can not be changed, construction method of the invention is taken out to old pot bearing and new pot bearing installation is suitable
Sequence adjust and optimized, and remains former pot bearing whole anchor bolt, new pot bearing make use of former pot bearing
Whole anchor bolts, reaching being reliably connected for new pot bearing and beam body and pinner, new pot bearing is unaffected using function,
The purpose that the new pot bearing later stage can be changed.
Compared with prior art, the present invention has following remarkable result：
(1) pot bearing of the invention changes the reliable anchoring that construction method ensure that pot bearing and beam body and pinner,
Reach with it is newly-built when the pot bearing installed as effect, it is ensured that the performance of pot bearing functional effect.
(2) pot bearing of the invention changes construction method without special construction technique, and no special material can with fabulous
Operability and practicality, there is good application prospect in old bridge reinforcement.
(3) the pot bearing of the invention replacing construction method later stage has convertibility, does not increase the work of later stage replacing
Amount.
