Technical Field

The invention relates to the field of civil engineering construction measurement auxiliary equipment, and provides an auxiliary device for measuring the pulling test displacement of an anti-floating anchor rod.

Background

the anti-floating anchor rod is used as a main reinforcing form applied to underground engineering underground water anti-floating at present, and is very important for the test of the bearing capacity of the anti-floating anchor rod. During the test, the displacement of the anti-floating anchor rod body needs to be measured, and the size and the speed of the displacement reflect the bearing capacity of the anti-floating anchor rod and the deformation condition of the fixed main body. Therefore, the displacement of the anti-floating anchor rod is one of important data which needs to be observed in a bearing capacity test, and the erection of the displacement meter is particularly critical.

In the prior art, most of the prior art is directly erected at the top end of an anchor rod or welded at the exposed part of a target anchor rod during testing, and the prior art is not detachable and is not beneficial to cyclic utilization; the shape of the fixing device is mostly circular, and the fixing device is only suitable for single-steel bar anchor rods and is not suitable for the condition of multi-steel bar anchor rods; generally, only one displacement meter can be erected at the same time, and the self error of the displacement meter cannot be eliminated.

Disclosure of Invention

Aiming at the problems that recycling is not facilitated, disassembly is inconvenient, a plurality of displacement meters cannot be erected at the same time, the size of the adaptive anchor rod is not wide enough and the like, the invention provides the auxiliary device for measuring the displacement of the anti-floating anchor rod in the drawing test.

In order to solve the technical problems, the invention adopts the technical scheme that the auxiliary device for measuring the displacement of the anti-floating anchor rod in the drawing test comprises the following components:

T-shaped thin-wall steel plate: the top plate is used for erecting a displacement meter, and the web plate is used for being in contact with and fixed with one end of an anti-floating anchor rod to be tested;

Rectangular thin-wall steel plate: the device is used for being in contact with and fixed with the other end of the anti-floating anchor rod, and the distance between the rectangular thin-wall steel plate and the web plate is adjusted according to the anti-floating anchor rods with different sizes;

Two groups of bolt holes are respectively arranged on the left side and the right side of the web plate and the rectangular thin-wall steel plate, and each group of bolt holes is divided into an upper bolt hole, a middle bolt hole and a lower bolt hole along the height direction;

The anti-floating anchor rod is fixedly connected with the bolt hole through a bolt and a nut.

Compared with the prior art, the technical scheme of the invention has the following beneficial effects:

The experimental device can be recycled, and waste is reduced; the device is simple and practical to manufacture, convenient to mount and dismount, and capable of accelerating the test efficiency; the anchor rod is suitable for a wide range of sizes and types of anchor rods, and can be suitable for single-steel bar and multi-steel bar anchor rods; the roof erects the displacement meter platform big, can erect the displacement meter of many different brands, precision simultaneously, reduces test utensil self error, increases experimental accuracy.

Detailed Description

Referring to fig. 1-3, the auxiliary device for measuring the displacement of the anti-floating anchor rod in the drawing test comprises the following components:

t-shaped thin-walled steel sheet 1: the top plate is used for erecting a displacement meter, and the web plate is used for being in contact with and fixed with one end of an anti-floating anchor rod to be tested;

Rectangular thin-wall steel plate 2: the device is used for being in contact with and fixed with the other end of the anti-floating anchor rod, and the distance between the rectangular thin-wall steel plate and the web plate is adjusted according to the anti-floating anchor rods with different sizes;

Two groups of bolt holes 3 are respectively arranged on the left side and the right side of the web plate and the rectangular thin-wall steel plate 2, and each group of bolt holes 3 is divided into an upper bolt hole 3, a middle bolt hole 3 and a lower bolt hole 3 along the height direction;

the anti-floating anchor rod is fixedly connected with the bolt hole 3 through a bolt and a nut 4.

the auxiliary device for measuring the displacement of the anti-floating anchor rod in the drawing test comprises the following steps when in use:

1) Bolts and nuts 4 are sleeved in the bolt holes 3 of the T-shaped thin-wall steel plate 1 and the rectangular thin-wall steel plate 2

2) the device is sleeved at the two end parts of the anti-floating anchor rod

3) the lower row of bolts and nuts 4 are screwed firstly, and after the leveling ruler is used for leveling, all the bolts and nuts 4 are screwed, so that the device is tightly fixed on the anti-floating anchor rod

4) the displacement meter is arranged on the top plate, and the test measurement can be started

5) after the test is finished, the bolt and the nut 4 are unscrewed, and the device can be easily taken down

The above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby. Equivalent changes and modifications made according to the patent scope and the specification of the present invention should be covered by the present invention.
