Technical Field

[0001] The utility model belongs to the technical field of ultra-high-speed low-vacuum construction, and more specifically relates to a relative height and flatness inspection tool. Background Art

[0002] The ultra-high-speed low-vacuum tube maglev transportation system uses superconducting magnetic levitation technology to break away from the ground to eliminate frictional resistance, and uses internal near-vacuum pipeline lines to significantly reduce air resistance, thereby achieving "near-ground flight" of more than 1,000 kilometers per hour. It is faster, more convenient, more comfortable, safer and economically controllable, and is the next generation of ultra-high-speed transportation.

[0003] During the actual construction process, the prefabricated tubular beam panel 100 is provided with a plurality of prefabricated panel sleeves 101 according to the design drawings, and a supporting boss 102 is provided at the lower portion of the prefabricated tubular beam panel 100. First, the installation accuracy of the prefabricated tubular beam panel is ensured during the preliminary construction. Secondly, since the supporting boss 102 is cast with concrete, the concrete pouring process often causes the upper surface of the supporting boss to be uneven, which in turn leads to an inconsistent distance between the supporting boss and the prefabricated tubular beam panel. Finally, when trimming the upper surface of the supporting boss, it is impossible to accurately grasp the trimming dimensions of each position. Utility Model Content

[0004] The purpose of the utility model is to provide a relative height and flatness inspection tool to solve the technical problem in the prior art that the trimming dimensions of each position cannot be accurately grasped when trimming the upper surface of a drop support boss.

The fixing member is connected to the precast tubular beam plate; the measuring member is disposed below the fixing member, with the top of the measuring member connected to the fixing member and the bottom surface of the measuring member being configured to contact the top surface of the support boss.

[0006] In a possible implementation, the fixing member is connected to the tubular beam prefabricated plate by bolts.

[0007] In one possible implementation, the fixing member is a T-shaped structure comprising a horizontal crossbar and vertical bars. The horizontal crossbar is provided with screw holes and is bolted to the tubular beam precast plate. The vertical bars are hollow tubular structures and are vertically arranged below the horizontal crossbar. The top ends of the vertical bars are fixedly connected to the horizontal crossbar.

The rod is vertically positioned and slidably inserted into the vertical rod; the base plate is horizontally positioned, with its upper surface fixedly connected to the bottom of the rod and its lower surface contacting the top surface of the support boss.

[0009] In a possible implementation, a locking screw is provided on the vertical pole.

[0014] In a possible implementation, the tooling material is aluminum alloy.

[0015] The beneficial effect of a relative height and flatness inspection tool provided by the present invention is that: compared with the prior art, the present invention includes a fixing part and a measuring part. First, the fixing part is connected to the pipe beam prefabricated plate, and the measuring part is arranged below the fixing part. The top of the measuring part is connected to the fixing part.

[0025] A relative height and flatness inspection tool provided by the present invention is now described.

[0026] Please also refer to Figure 1 and Figure 2 The first embodiment of the present invention provides a relative height and flatness inspection tool, which includes a fixing member 1 and a measuring member 2. The fixing member 1 is connected to the precast tubular beam plate 100; the measuring member 2 is disposed below the fixing member 1, with the top of the measuring member 2 connected to the fixing member 1 and the bottom surface of the measuring member 2 being in contact with the top surface of the support boss 102.

[0027] The present embodiment provides a relative height and flatness inspection tool. Compared with the prior art, first, the fixing part 1 is connected to the tubular beam prefabricated plate 100, and the measuring part 2 is arranged below the fixing part 1, and the top of the measuring part 2 is connected to the fixing part 1. Since the tubular beam prefabricated plate 100 has been fine-tuned in place in the early stage, when the inspection tool is used, if the height of the supporting boss 102 relative to the tubular beam prefabricated plate 100 exceeds the theoretical data, the tool cannot be installed in place; if the height of the supporting boss 102 relative to the tubular beam prefabricated plate 100 is lower than the theoretical data, a gap will be generated between the bottom surface of the tool and the boss. At this time, the data obtained by inserting the feeler gauge into the gap is the specific data of the relative height of the boss lower than the theory. The data of each part of the supporting boss 102 is recorded to solve the technical problem in the prior art that the trimming size of each position cannot be accurately grasped when trimming the upper surface of the hanging supporting boss 102.

[0028] Specifically, a sleeve 101 is provided on the tubular beam prefabricated plate 100, and the fixing member 1 is screwed to the tubular beam prefabricated plate 100 via bolts 4 and the sleeve 101. Since the sleeves 101 on the tubular beam prefabricated plate 100 are all finely adjusted, connecting the fixing member 1 and the sleeve 101 via bolts 4 allows for precise positioning of the fixing member 1 without damaging the sleeve 101, thereby improving measurement accuracy.

[0029] Based on the above embodiments, the present application provides a first specific embodiment in which the fixing member 1 is a T-shaped structure, comprising a horizontal bar 11 and a vertical bar 12. The horizontal bar 11 is arranged horizontally and has screw holes therein. The horizontal bar 11 is connected to the tubular beam prefabricated plate 100 by bolts 4. The vertical bar 12 is a hollow tubular object, arranged vertically below the horizontal bar 11, and the top of the vertical bar 12 is fixedly connected to the horizontal bar 11.

[0030] The fixing member 1 adopts a T-shaped structure, which can connect the cross bar 11 with the two bolt holes 4 on the tubular beam prefabricated plate 100, thereby improving the stability of the connection between the cross bar 11 and the tubular beam prefabricated plate 100 and maintaining the horizontality of the cross bar 11 during use.

[0031] Furthermore, the measuring member 2 is a T-shaped structure, comprising an insert rod 21 and a base plate 22. The insert rod 21 is vertically arranged and slidably inserted into the vertical rod 12; the base plate 22 is horizontally arranged, with the upper surface of the base plate 22 fixedly connected to the bottom of the insert rod 21, and the lower surface of the base plate 22 is used to contact the top surface of the support boss 102.

[0032] When the insert rod 21 is inserted into the vertical post 12, since the insert rod 21 can slide up and down along the vertical direction of the vertical post 12, when the base plate 22 is placed horizontally on the upper surface of the support boss 102, the relative position of the insert rod 21 and the vertical post 12 can be adjusted according to the height of the support boss 102 and the prefabricated tubular beam slab 100. Furthermore, to facilitate the observation of the distance the insert rod 21 moves relative to the vertical post 12, a scale is provided on the insert rod 21. The zero mark on the scale represents the theoretical value of the prefabricated tubular beam slab 100 and the support boss 102. The lower edge of the vertical post 12 is used as the standard reading line, and there are 1-20mm scales above and below the zero mark. If the worker reads several millimeters above the zero mark, it means that the support boss 102 is several millimeters lower than the prefabricated tubular beam slab 100. Conversely, if the worker reads several millimeters below the zero mark, it means that the support boss 102 is several millimeters higher than the prefabricated tubular beam slab 100.

[0033] After measuring the relative height between the support boss 102 and the precast tubular beam plate 100, the locking screw 3 on the vertical rod 12 is rotated, and the bottom of the locking screw 3 abuts the insertion rod 21, thereby fixing the relative position of the fixing member 1 and the measuring member 2. After the relative position of the fixing member 1 and the measuring member 2 is fixed, the worker uses a feeler gauge to insert the gap between the bottom plate 22 and the upper surface of the support boss 102 to measure the height difference between the highest and lowest points on the upper surface of the support boss 102, thereby checking the flatness of the upper surface of the boss.

[0034] Based on the above embodiment, the fixing member 1 further includes two first stiffening plates 13, which are respectively provided on either side of the vertical rod 12. The ends of the first stiffening plates 13 are respectively connected to the vertical rod 12 and the cross bar 11. The first stiffening plates 13 not only enhance the connection strength between the vertical rod 12 and the cross bar 11, but also prevent positional offset between the vertical rod 12 and the cross bar 11.

[0035] In addition to the above embodiment, the measuring member 2 further includes two second stiffening plates 23, one located on either side of the insertion rod 21. The two ends of the second stiffening plates 23 are connected to the insertion rod 21 and the base plate 22, respectively. The second stiffening plates 23 not only strengthen the connection between the insertion rod 21 and the base plate 22, but also prevent positional offset between the insertion rod 21 and the base plate 22.

[0036] Specifically, the crossbar 11 is an angle steel.

[0037] Specifically, the tooling is made of aluminum alloy. Aluminum alloy has low density but high strength, close to or exceeding that of high-quality steel, good plasticity, can be processed into various profiles, and has excellent electrical conductivity, thermal conductivity and corrosion resistance.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
