Abstract
The utility model relates to a fixture for performing stretching and load ensuring tests on ultrashort bolts for bridges. The fixture comprises two oppositely placed bases (1), two bolt sleeves (2) and one fixed nut (5). The fixture disclosed by the utility model fundamentally solves the problem that clamping can not be performed due to a test space problem of a tensile machine in the process of performing stretching and load ensuring tests on the ultrashort bolts for bridges. The fixture disclosed by the utility model is simple in structure and easy to use.
Description
Technical field
The utility model relates to a kind of stretching of ultrashort bolt and guarantees load test fixture, is mainly used in the problem that ultrashort bolt that solution causes due to testing machine test space cannot clamping.Belong to technical field of measurement and test.
Background technology
Bridge need to stretch and guarantee load test with bolt, wherein tension test be test bolt reach to stressed, guarantee that load test is that test bolt carries horizontal stressed.
Owing to affected by the test space of puller system, some ultrashort bolt samples cannot clamping on puller system, thereby causes the stretching of ultrashort bolt and guarantee that load test cannot carry out.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the ultrashort bolt test fixture of high strength for a kind of bridge is provided.
The purpose of this utility model is achieved in that
A kind of bridge stretches with ultrashort bolt and guarantees the fixture of load test, for clamping bolt, stretch and guarantee load test, be characterized in: described fixture comprises two pedestals staggered relatively, two bolt sleeves and a hold-down nut, the inside of each bolt sleeve is provided with stepped hole, described two bolt sleeves stretch into respectively two pedestals and coordinate with base thread, the head of described bolt and the stepped hole of one of them bolt sleeve offset, the screw rod of bolt passes the stepped hole of another bolt sleeve and coordinates with hold-down nut, the stepped hole of described hold-down nut and another bolt sleeve offsets.
A kind of bridge of the utility model stretches with ultrashort bolt and guarantees the fixture of load test, and the far-end of two pedestal is provided with square nut.
Compared with prior art, the beneficial effects of the utility model are:
A kind of bridge of the utility model stretches with ultrashort bolt and guarantees the fixture of load test, fundamentally solved bridge with the ultrashort bolt of high strength when stretching or guarantee load test due to the problem of puller system test space cause cannot clamping a difficult problem.And of the present utility model simple in structure, easy to use.
