Detailed Description

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments of the present invention when taken in conjunction with the accompanying drawings. Like reference numerals refer to like parts throughout the drawings. The drawings are not intended to be to scale, emphasis instead being placed upon illustrating the principles of the invention.

As shown in figure 1, the novel measuring rod is mainly used for measuring the beam member of a building, and the measuring work can be finished on the ground without climbing to the beam member. The measuring stick mainly includes pothook 1, controls two measuring arms 2, slide rail 3 and holds pole 4, and two measuring arms 2's top all is provided with about controlling pothook 1, controls two measuring arms 2's bottom slidable and installs on slide rail 3, holds pole 4 and is fixed in on the slide rail 3, holds pole 4 and is a hollow rod, and measuring silk 5 passes hold pole 4. The bottom ends of the left and right measuring arms 2 are hinged to a left pull rod 9 and a right pull rod 7 respectively, the left pull rod 9 and the right pull rod 7 are fixed on the holding rod 4 through a pin shaft 8 after being crossed to form two equal-arm levers, namely, an upper opening L1 between the left pull rod 9 and the right pull rod 7 is equal to the width of a lower opening L2, the width of an upper opening L1 is equal to the width between the left and right measuring arms 2, and the left pull rod 9 and the right pull rod 7 are connected with the pull rope 6 respectively.

Referring to fig. 2, a measuring space 10 for accommodating a beam member is formed between the left and right measuring arms 2, the hook 1 is substantially in the shape of ┍ and is installed at the top end of the measuring arm 2 through a rotating shaft 1.2, the hook 1 includes a horizontal portion 1.1 and a vertical portion 1.3, the horizontal portion 1.1 and the vertical portion 1.3 are perpendicular to each other, the vertical portion 1.3 is clamped at the outer side of the measuring arm 2, the hook 1 can rotate towards the measuring space 10 around the rotating shaft 1.2, and when the horizontal portion 1.1 is in a horizontal state, the vertical portion 1.3 is clamped at the outer side of the measuring arm 2 to prevent the hook 1 from rotating outwards. Wherein, a torsion spring can be arranged in the rotating shaft 1.2, so that after the hook 1 rotates towards the measuring space 10, the hook 1 can be restored to a horizontal state under the action of the torsion spring.

The measurement process of the measuring rod will be described in detail with reference to fig. 3 to 7. Taking a supporting beam of a measuring roof as an example, as shown in fig. 3, during measurement, the holding rod 4 is held by hand to lift the measuring rod up to the supporting beam, the supporting beam abuts against the hook 1, and as the holding rod 4 is lifted up, the hook 1 is pushed by the supporting beam to rotate towards the measuring space 10, and the supporting beam gradually enters into the measuring space 10. Then, the holding rod 4 is continuously lifted upwards, so that the support beam completely enters the measuring space 10, the support beam does not abut against the hook 1 any more, and the hook 1 is reversed to be in a horizontal state under the action of the torsion spring, and the state shown in fig. 4 is reached.

Then, as shown in fig. 5, the holding rod 4 is pulled downwards, the inner side of the hook 1 is clamped on the supporting beam, the hook 1 cannot rotate outwards due to the blocking of the vertical part 1.3, and the measuring rod can be stably clamped on the supporting beam through the hook 1. And then the pull rope 6 is pulled to enable the left and right measuring arms 2 to press the slide rail 3 to slide towards the support beam until the left and right measuring arms 2 clamp the support beam, and the left pull rod 9 and the right pull rod 7 are equal-arm levers, so that the width L3 between the two pull ropes 6 is the width of the support beam, as shown in figure 6, and the width L3 between the two pull ropes 6 can be measured on the ground through a tape measure to obtain the width of the support beam.

Referring to fig. 7, after the measuring rod is stably clamped on the support beam by the hook 1, the measuring wire 5 is passed through the holding rod 4, so that the measuring wire 5 abuts against the support beam, and the length L5 of the measuring wire 5 extending into the measuring space 10 can be measured, and the length L4 of the measuring arm 2 is a known fixed value L4, so that the height of the support beam is L4-L5. After the measurement is finished, the holding rod 4 is swung left and right, so that the left and right measuring arms 2 can slide outwards along the sliding rails 3 to be separated under the action of the supporting beam, and the supporting beam 4 can be separated from the measuring space 10.

The method can conveniently measure the size information of the beam on the ground, is simple, convenient and quick to operate, has high measuring accuracy, does not need to climb to the position near the beam, and has high measuring safety.

In the previous description, numerous specific details were set forth in order to provide a thorough understanding of the present invention. The foregoing description is only illustrative of the preferred embodiments of this invention and, therefore, the invention is not limited to the specific details disclosed herein, since the invention can be practiced in many other ways than those specifically described herein.
