Description

Technical Field

[0001] The utility model belongs to the technical field of building measurement, in particular to a device for measuring the spacing between steel bars and the thickness of protective layers. Background Art

[0002] Nowadays, the scope of use of concrete structure projects is becoming wider and wider, and the requirements for the thickness of the steel bar protective layer and the spacing of the steel bars in concrete are becoming higher and higher. Because the thickness of the steel bar protective layer and the spacing of the steel bars directly affect the service life of the steel bars, and the steel bars directly affect the bearing capacity and durability of the concrete structure, the project has a strict acceptance process for the thickness of the steel bar protective layer and the spacing of the steel bars during the construction process.

[0003] During the current construction process, the thickness and spacing of the steel bar cover are measured using a ruler, which has the following shortcomings: the ruler is easily tilted, resulting in inaccurate measurement and unable to guarantee measurement accuracy. After measuring the thickness of the cover, the measuring point needs to be changed and the ruler needs to be extended into the steel bars in the beam. Due to the small space at the measuring point, the ruler is very inconvenient when measuring the steel bar spacing, which affects the measurement efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides a device for measuring the spacing between steel bars and the thickness of protective layer. The technical solutions adopted are as follows:

[0005] A device for measuring the spacing between steel bars and the thickness of a protective layer includes an outer frame, a thickness measuring groove for mounting a thickness measuring mechanism is formed on one side of the upper surface of the outer frame, and a spacing measuring groove for mounting the spacing measuring mechanism is formed on the other side of the upper surface of the outer frame. The thickness measuring mechanism includes a sliding frame located within the thickness measuring groove, and a measuring ruler that can move up and down is provided within the sliding frame.

[0006] The spacing measurement mechanism includes a movable block placed inside the spacing measurement slot and a measuring block. A measuring rod is provided on one side of the measuring block facing the movable block, and the tail end of the measuring rod passes through the inside of the movable block.

[0007] Furthermore, a fixed block is provided in the sliding frame and on one side of the measuring ruler, and the fixed block is movably connected to a rotatable rotating block.

[0008] Furthermore, first sliding bars are respectively provided on both sides of the sliding frame, and first sliding grooves for embedding the first sliding bars are respectively provided on both sides of the interior of the thickness measuring groove.

[0009] Furthermore, second slide bars are provided on both sides of the movable block and the measuring block, and second slide grooves for embedding the second slide bars are provided on both sides of the spacing measuring groove.

[0010] Furthermore, a protruding rod is provided on the same side of the movable block and the measuring block respectively, and a slot for the protruding rod to pass through and slide is provided on one side of the spacing measuring groove. A nut is connected to one end of the protruding rod in the movable block and the measuring block after passing through the slot, and the movable block and the measuring block can be fixed by tightening the nut.

[0011] Furthermore, a telescopic slot for placing the telescopic block is provided on the inner side of the movable block and the measuring block, and a fixing bolt is provided on the other side of the movable block and the measuring block. By tightening the fixing bolt, the telescopic block can be kept fixed.

[0012] Furthermore, a groove is provided on both sides of the measuring ruler and the telescopic block, and protrusions connected to the groove are provided on both sides of the sliding frame and the inside of the telescopic slot, respectively, so that the measuring ruler or the telescopic block can remain stable during the descent process without deviation, thereby maintaining measurement accuracy.

[0013] Furthermore, the inner surface of the telescopic block is in the same plane as the inner surface of the movable block or the measuring block. When the movable block or the measuring block itself cannot contact the steel bar, the telescopic block can be lowered to make it stick to the steel bar, which is equivalent to the movable block or the measuring block contacting the steel bar, thereby improving the scope of application.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model arranges a thickness measuring mechanism and a spacing measuring mechanism in the outer frame. When measuring the thickness of the protective layer, there is no need to move the position of the device, and the spacing between the steel bars can be continued to be measured. The use is more convenient and the measurement efficiency can be improved. Moreover, when measuring the thickness of the protective layer, the outer frame is flush with the construction surface, and when the measuring ruler descends and contacts the steel bars, no shaking occurs, which can ensure the accuracy of the measurement result.

[0016] The utility model arranges a telescopic block in the spacing measuring mechanism so that when the depth of the steel bar is deep, the movable block and the measuring block can still contact the surface of the steel bar through the telescopic block, and the inner surface of the telescopic block is in the same plane as the inner surface of the movable block or the measuring block, so it does not affect the accuracy of the measurement result, thereby improving its practicality.

DETAILED DESCRIPTION

[0026] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0027] As attached Figure 1-7 shown.

[0028] The device for measuring the spacing between steel bars and the thickness of the protective layer includes an outer frame 1 of a rectangular structure, and two rectangular slots are respectively opened on the upper surface of the outer frame, one of the slots is a thickness measuring slot 2 for installing a thickness measuring mechanism, and the other slot is a spacing measuring slot 3 for installing a spacing measuring mechanism.

[0029] The thickness measuring mechanism includes a sliding frame 21 located inside the thickness measuring slot 2, a first slide bar 22 is provided on both sides of the sliding frame 21, a measuring ruler 25 that can move up and down is provided inside the sliding frame 21, and a fixed block 23 is provided inside the sliding frame 21 and on one side of the measuring ruler 25. The fixed block 23 is movably connected to a rotatable rotating block 24, as shown in the attached figure. Figure 5-7 As shown, when the rotating block 24 is located above the fixed block 23, it has no contact with the measuring ruler 25, and the measuring ruler 25 can move up and down at will; when the rotating block 24 is located on the side of the fixed block 23, it contacts the measuring ruler 25, and the measuring ruler 25 cannot move downward.

[0030] In order to ensure that the measuring ruler 25 can rise and fall smoothly without deviation, a groove is provided on both sides of the measuring ruler 25 , and a protrusion connected to the groove is provided on the inner side of the sliding frame 21 .

[0031] In order to enable the sliding frame 21 to slide inside the thickness measuring groove 2 , first sliding grooves 11 for the first sliding bars 22 to be embedded in are provided on both sides of the thickness measuring groove 2 .

[0032] The thickness measuring mechanism is used as follows: place the outer frame 1 on the construction surface of the area to be measured, rotate the rotating block 24 so that it is not in contact with the measuring ruler 25, and then the measuring ruler 25 can be lowered, and the bottom of the measuring ruler 25 is in contact with the side of the steel bar, and then the reading of the measuring ruler 25 can be read; if the measuring position is not easy to observe the reading, the rotating block 24 can be lowered so that it is in contact with the measuring ruler 25, and the measuring ruler 25 can be fixed. Then the outer frame 1 can be removed to obtain the observed value.

[0033] For ease of reading, see the attached Figure 4 As shown in the figure, the scale lines on the surface of the measuring ruler 25 start from the upper surface of the sliding frame 21. After the measuring ruler 25 is lowered, as shown in the attached figure, Figure 7 As shown, it is sufficient to directly observe the scale line value on the measuring ruler 25 corresponding to the upper edge of the sliding frame 21.

[0034] The spacing measurement mechanism includes a movable block 31 and a measuring block 32 placed inside the spacing measurement groove 3. A measuring rod 33 is provided on the side of the measuring block 32 facing the movable block 31, and the tail end of the measuring rod 33 passes through the inside of the movable block 31; a second sliding bar 35 is provided on both sides of the movable block 31 and the measuring block 32, and a protruding rod 34 is provided on the same side of the movable block 31 and the measuring block 32.

[0035] In order to enable the movable block 31 and the measuring block 32 to slide in the distance measuring groove 3 , second sliding grooves 12 for the second slide bar 35 to be embedded in are provided on both sides of the distance measuring groove 3 .

[0036] In order to enable the movable block 31 and the measuring block 32 to be fixed at a certain position in the spacing measuring groove 3, a slot 13 for the protruding rod 34 to pass through and slide is opened on one side of the spacing measuring groove 3. The protruding rod 34 in the movable block 31 and the measuring block 32 is connected to a nut at one end after passing through the slot 13. By tightening the nut, the movable block 31 and the measuring block 32 can be controlled to be fixed.

[0037] When the spacing measuring mechanism is in use, in order to prevent the movable block 31 and the measuring block 32 from contacting the steel bars due to the deep depth of the steel bars, a telescopic groove 38 for placing the telescopic block 36 is provided on the inner side of the movable block 31 and the measuring block 32, and a fixing bolt 37 is provided on the other side of the movable block 31 and the measuring block 32. By tightening the fixing bolt 37, the telescopic groove 38 can be controlled to be fixed.

[0038] In order to make the telescopic block 36 move straight up and down, protrusions identical to those inside the sliding frame 21 are provided on both sides of the telescopic slot 38 , and grooves identical to those outside the measuring ruler 25 are provided on both sides of the telescopic block 36 .

[0039] The spacing measurement mechanism is used as follows: the outer frame 1 is placed on the construction surface of the area to be measured, the movable block 31 and the measuring block 32 are placed between the steel bars to be measured, and the movable block 31 or the measuring block 32 is slid so that the inner side surfaces of the lower ends of the two are respectively abutted against the side surfaces of the steel bars. At this time, the spacing between the two steel bars can be known by observing the measuring rod 33.

[0040] If the steel bar is deep and the movable block 31 and the measuring block 32 cannot contact the steel bar, just loosen the fixing bolt 37 and lower the telescopic block 36. Since the inner surface of the telescopic block 36 is in the same plane as the inner surface of the movable block 31 or the measuring block 32, it will not affect the accuracy of the measurement result.

[0041] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
