Abstract
Description
Technical Field
[0001] The utility model belongs to the field of construction engineering, and in particular relates to a steel bar mechanical connection inspection marking tool. Background Art
[0002] At present, the quality inspection of mechanical connection of steel bars is to check the quality of the connection. The connection quality inspection is very important. During the inspection, in addition to checking the quality, flatness, and firmness of the connection sleeve, it is also necessary to check whether there is a gap at the connection between the two steel bars. At present, most of them use traditional inspection methods to inspect the gap, that is, unscrew the connected sleeve and then inspect it. This traditional inspection method consumes a lot of manpower and time, especially for projects with a large number of mechanical connections of steel bars. It is impossible to achieve full coverage inspection and cannot guarantee the quality of mechanical connections. Summary of the invention
[0003] The problem to be solved by the present invention is to overcome the shortcomings of the background technology and provide a steel bar mechanical connection inspection marking tool.
[0004] The present invention is achieved through the following technical solutions:
[0005] A steel bar mechanical connection inspection and marking tool comprises a rectangular tube and a short square tube welded together, wherein the rectangular tube and the short square tube are L-shaped; a square sleeve is sleeved on the rectangular tube, and a threaded hole A is provided on the outer side of the square sleeve, through which a bolt A passes, and the square sleeve is fastened to the rectangular tube by bolt A; a circular ring is welded on the opposite outer side of the outer side of the square sleeve where the threaded hole A is located, and a threaded hole B is provided on the outer side of the circular ring, through which a bolt B passes, and a marking pen is provided in the circular ring, and the marking pen is fastened in the circular ring by bolt B; a scale is provided on the rectangular tube.
[0006] Preferably, the scale range is between 0-15 cm.
[0007] Preferably, the marking pen is a paint pen.
[0008] Preferably, the rectangular tube and the short square tube have a side length of 1 cm and a thickness of 1.5 mm.
[0009] The tool of the present invention can mark the steel wire heads connected at both ends before the steel bars are mechanically connected. Through the early marking, the gap at the connection can be inspected later. During the inspection, there is no need to unscrew the sleeve, and only the distance between the marked parts of the steel bars at both ends needs to be measured. It is faster and more convenient than the traditional method, greatly improving the efficiency of the connection gap inspection, and the marking position can be adjusted according to needs, with greater flexibility.

[0011] Figure 2 This is a schematic diagram of the structure from another angle of this embodiment.
[0012] In the figure, 1 is a rectangular tube, 2 is a short square tube, 3 is a square sleeve, 4 is a bolt A, 5 is a ring, 6 is a bolt B, and 7 is a marking pen. DETAILED DESCRIPTION
[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.
[0014] This embodiment includes a rectangular tube 1 and a short square tube 2. The ends of the rectangular tube 1 and the short square tube 2 are welded together to form an L shape. The rectangular tube 1 and the short square tube 2 used in this embodiment have a side length of 1 cm and a thickness of 1.5 mm. In order to reduce weight, the rectangular tube 1 and the short square tube 2 are both hollow square tubes. A square sliding sleeve 3 is sleeved on the rectangular tube 1. The square sliding sleeve 3 can slide along the rectangular tube 1. A threaded hole A is provided on the outer side of the square sliding sleeve 3. Bolts A4 pass through the threaded hole A. The square sliding sleeve 3 can be fastened to the rectangular tube 1 by tightening the bolts A4. A circular ring 5 is welded on the outer side of the square sleeve 3 where the threaded hole A is located. The outer side of the circular ring 5 is provided with a threaded hole B. The bolt B6 passes through the threaded hole B. A marking pen 7 is passed through the circular ring 5. The marking pen 7 is perpendicular to the circular ring 5. The inner diameter of the circular ring 5 is slightly larger than the outer diameter of the marking pen 7. The bolt B6 is against the marking pen 7. The marking pen 7 can be fastened in the circular ring 5 by the bolt B6. The marking pen 7 is parallel to the short square tube 2. The marking pen 7 is used to mark the steel wire head to be connected. In order to make the mark not easy to be worn, the marking pen 7 is preferably a paint pen. The paint pen is easy to mark on the steel bar and the mark is not easy to be worn away. A scale is provided on the rectangular tube 1, which is not drawn in the scale figure. The preferred scale is zero scale point from the inner side of the short square tube 2. The inner side here refers to the side facing the marking pen 7. The preferred scale range is between 0-15cm.
[0015] When the tool of the present invention is used, first put the marking pen 7 into the circular ring 5, then tighten the bolt B6 to fix the marking pen 7, slide the square sliding sleeve 3 to a certain position, and determine the horizontal distance between the marking pen 7 and the inner side of the short square tube 2 according to the scale on the rectangular tube 1. The horizontal distance between the marking pen 7 and the inner side of the short square tube 2 can be greater than half of the length of the sleeve, that is, after the sleeve is used to mechanically connect the two steel bars later, the mark can still be exposed and will not be covered by the sleeve. In this embodiment, it is preferred to set the horizontal distance between the marking pen 7 and the inner side of the short square tube 2 to 10 cm, and then tighten the bolt A4 to fix the square sliding sleeve 3, and then mechanically connect the two steel bars. Before the connection, let the inner side of the short square tube 2 be close to the end of the steel bar, and the rectangular tube 1 be parallel to the steel bar. Then use the marking pen 7 to mark the steel bar. The distance between the mark and the end of the steel bar is 10cm. The same method is used to make such a mark on another steel bar. If the two steel bars are tightly connected, the distance between the two marks on the two steel bars should be 20cm. In this way, after the two steel bars are mechanically connected through the sleeve in the later stage, it can be directly determined by measuring the distance between the two marks whether there is a gap at the joint of the two steel bars after the mechanical connection of the steel bars. If the distance between the two marks is greater than 20cm, it means that the two steel bars are not tightly connected and there is a gap at the joint. The method of using the tool of the present invention to mark in advance and then directly check whether there is a gap at the joint of the steel bars at both ends by marking does not require unscrewing the sleeve, and the inspection efficiency is greatly improved compared with the traditional inspection method.
[0016] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
