Description
Technical field
The present invention relates to the lockset technology, relate in particular to a kind of combined type girder steel lock and anti-float anchor rod reception test method.
Background technology
Along with the fast development of society modernization, superelevation, the ultra-large type building structure take large-scale shopping plaza, museum etc. as representative emerges in large numbers the life periphery people like the mushrooms after rain.Advantages such as meanwhile, the base form of " raft plate+anti-float anchor rod (referring to resist buildings to the general name of the various stake types of top offset) " is dark with its buried depth, rigidity is large, globality is strong, shock resistance is good and by this class formation institute widespread use.
The examination of anti-float anchor rod is after its construction is finished, and carries out fundamental test (damage type) and two kinds of tests of reception test (non-damage type).Reception test is carried out code requirement according to the quantity of designing requirement: the anti-float anchor rod in the same rock stratum of Same Site, the experiment number must not be less than 5% of total anti-float anchor rod, and should not be less than 6.
Reception test mainly adopts the center pit method at present, the method is to cut away (usually adopting the oxygen-acetylene excision) with anti-float anchor rod horizontal curved anchor or with the expansion head dummy anchoring of anti-float anchor rod, and the straight section of anti-float anchor rod is inserted in the center pit of hydraulic jack (band center pit), lockset pins anti-float anchor rod, utilize the hydraulic jack pressurization, the test of carrying out anti-float anchor rod detects.After reception test is finished, anti-float anchor rod horizontal curved anchor maybe will be enlarged the head dummy anchoring recover, and namely take welding manner to recover according to designing requirement to cut-out, will enlarge the head dummy anchoring and recover usually to adopt single-selded lap joint or welding by both sides to recover.
Namely existing reception test is proving test, need to anti-float anchor rod excise, the operation such as recovery.Mainly there is following shortcoming in existing reception test: the cycle is grown, wastes time and energy, and before the reception test, needs excise completed horizontal anchoring section or enlarge the head dummy anchoring with oxygen-acetylene; After reception test is finished, must take welding manner to recover to cut-out according to designing requirement; Affect the anti-float anchor rod quality, when recovering to adopt welding manner to recover, have the quality risk that reduces former designing requirement.
Summary of the invention
The object of the invention is to, checking and accepting experimental technique for above-mentioned existing anti-float anchor rod is destructive test, there is cycle length, wastes time and energy and affects the problem of anti-float anchor rod quality, a kind of combined type girder steel lock is proposed, this combined type girder steel lock construction advantages of simple, easy to use adopts the non-destructive reception test that this combined type girder steel can save time, anti-float anchor rod is realized in the labour-saving.
For achieving the above object, the technical solution used in the present invention is: a kind of combined type girder steel lock, comprise the jig that can form the taper lockhole after two merging, and after merging, described two jigs can be connected and fixed by web member; Be equipped with locking plate in the described taper lockhole; Described jig periphery is provided with boss.
Further, described taper lockhole is opening up.
Further, described taper lockhole is two.
Further, described web member is the screw bolt and nut that is equipped with, and described two jigs cooperate is provided with through hole and fixes by nut, realizes the fixing of two jigs.Described bolt is two.
Another object of the present invention also provides a kind of anti-float anchor rod reception test method, the non-destructive reception test that the method can save time, anti-float anchor rod is realized in the labour-saving.
For achieving the above object, the technical solution used in the present invention is: a kind of anti-float anchor rod reception test method, the method adopts described combined type girder steel lock, anti-float anchor rod is placed the taper lockhole of combined type girder steel lock, and between taper lockhole and anti-float anchor rod, add locking plate, make the locking of anti-float anchor rod and combined type girder steel lock; Between boss and ground, lifting jack is set, opens lifting jack, realize the reception test of anti-float anchor rod.
Further, described lifting jack is two, and the piston of two described lifting jack is against the lower plane of combined type girder steel lock both sides boss.
Combined type girder steel lock construction of the present invention is simple, reasonable, compact, overcome the defective workmanship that existing anti-float anchor rod test testing tool brings, the present invention adopts described combined type girder steel to be locked into capable anti-float anchor rod reception test, need not to excise anti-float anchor rod horizontal curved anchor or enlarge the head dummy anchored end, also just do not exist anti-float anchor rod to recover.Namely adopt described combined type girder steel to be locked into capable anti-float anchor rod reception test, energy short form test characterization processes improves anti-float anchor rod test detection efficiency, and Elimination test detects the hidden danger of quality that brings to anti-float anchor rod, and Elimination test detects the impact on the construction period progress.Be appreciated that combined type girder steel lock of the present invention also can be used for the fundamental test of anti-float anchor rod.
