Abstract
The utility model discloses a device for testing the pull-out resistance of a grouting hole bolt of a concrete segment. The device comprises the concrete segment (1), and is characterized in that a cushion block (2) is arranged on one side of the concrete segment (1); one end of a rigid screw rod (3) passes through the cushion block (2) and is connected with the grouting hole bolt (8) mounted on an inner arc surface of the concrete segment (1); a cross-core jack (4) is further mounted on the rigid screw rod (3); one end of the cross-core jack (4) is propped against the tail end of the rigid screw rod (3), and the other end of the cross-core jack (4) is propped against the cushion block (2). The device has a simple and practical structure, is convenient to carry, is convenient to use in the field, can test the pull-out resistance of the grouting hole bolt rapidly and conveniently, facilitates the test, the research and the development of products by bolt manufacturers, and can save a large amount of test costs.
Description
Technical field
The utility model relates to a kind of test unit of concrete pipe sheet grouting hole bolt withdrawal resistance.
Background technology
At present, employed concrete pipe sheet is used more in the shield-tunneling construction, for improving the extraction-resistant behavior of concrete pipe sheet grouting hole bolt, reinforcement is to the production control and the erecting stage control of section of jurisdiction, to avoiding the section of jurisdiction lifting to come off, improve the security that install the section of jurisdiction, its test method is also constantly perfect in practice.
At present because the variation of concrete pipe sheet specification, model, so the withdrawal resistance pick-up unit form of concrete pipe sheet grouting hole bolt is more various, but their range of application is narrow usually, and general volume is bigger, can't carry, can not accomplish in time to detect grouting hole bolt withdrawal resistance in production, working-yard.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, provides a kind of cost low, applied widely, portable concrete pipe sheet grouting hole bolt pull-out bond test device.
The technical solution adopted in the utility model is as follows:
A kind of concrete pipe sheet grouting hole bolt pull-out bond test device, comprise concrete pipe sheet, a side that it is characterized in that described concrete pipe sheet is provided with cushion block, rigid threaded rod one end passes cushion block and links to each other with grouting hole bolt on the concrete pipe sheet intrados, the punching lifting jack also is installed on rigid threaded rod, described punching lifting jack one end leans the tail end of rigid threaded rod, and the other end withstands on the cushion block.
Described cushion block is the steel cushion block.
Between described cushion block and the concrete pipe sheet rubber blanket is installed.
The two ends of described rigid threaded rod are equipped with screw thread, and the one end is threaded in the grouting hole bolt on the concrete pipe sheet intrados, and the other end is equipped with nut, and the outside of described cushion block leans the residence and states nut.
Be provided with conical through-hole in the described cushion block, described rigid threaded rod is installed in this conical through-hole.
The beneficial effects of the utility model have:
Simple and practical, easy to carry, be convenient to on-the-spot the use, can test grouting hole bolt withdrawal resistance fast, easily, and be convenient to of the test research and development of bolt manufacturer product, can save experimentation cost in a large number.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model has been sidelong cushion block 2 at one of concrete pipe sheet 1, and the one side that cushion block 2 contacts with concrete pipe sheet 1 adopts arc process, and cushion block 2 can be for the steel cushion block or with the higher cushion block of other intensity.Rigid threaded rod 3 one ends pass punching lifting jack 4 respectively and link to each other with the grouting hole bolt 8 that is installed in concrete pipe sheet 1 with cushion block 2.The two ends of rigid threaded rod 3 are equipped with screw thread, and the one end is threaded in the grouting hole bolt 8 of concrete pipe sheet 1, and the other end is equipped with nut 6, and the outside of cushion block 2 leans described nut 6.
Between described cushion block 2 and the concrete pipe sheet 1 rubber blanket 5 is installed, and be provided with conical through-hole 7 in the cushion block 2, rigid threaded rod 3 is installed in this conical through-hole 7, adopts conical through-hole 7 to form hydraucone in the bottom of cushion block 2, can reduce stress influence, reach and do not fetter concrete purpose.It is tight, stressed even that rubber blanket 5 can make cushion block 2 contact with concrete pipe sheet 1.
The utility model in use, the grouting hole bolt 8 of rigid threaded rod 3 with concrete pipe sheet 1 to be measured is connected and fixed, rigid threaded rod 3 will tighten at the end, rubber blanket 5 on concrete pipe sheet 1 intrados pad, cushion block 2 contacts with rubber blanket 5, align, on cushion block 2, place punching lifting jack 4, then at the rigid threaded rod 3 afterbodys nut 6 of screwing on.4 work of punching lifting jack, rise in its axle center, and rigid threaded rod 3 is upwards drawn, and thread is stressed, and after punching lifting jack 4 power value readings showed maximum, then this value was the maximum pull of bolt hole.
Other undeclared part that the utility model relates to is same as the prior art.
