Description

Technical Field

[0001] The utility model relates to the technical field of building construction measurement equipment, in particular to a benchmark for building construction measurement. Background Art

[0002] Housing construction refers to a project with a roof, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, living, learning, and public activities. Surveying poles are often used for alignment during housing construction.

[0003] The traditional benchmark is an independent benchmark body. When in use, it needs to be manually held to place the benchmark vertically on the ground. Holding the benchmark for a long time will cause soreness in the hands of the workers, thereby affecting the stability of the benchmark during the measurement process. Therefore, benchmarks equipped with tripods have appeared on the market. When in use, the tripod supports the benchmark, effectively avoiding the problem of soreness in the hands of the workers caused by holding the benchmark for a long time. However, in actual use, there are still the following defects:

[0004] Since the ground of a building construction site is generally uneven, when placing and positioning the benchmark, after placing the tripod on the ground to support the benchmark, the tripod needs to be adjusted and measured with a level ruler to make the benchmark vertical. The overall operation is cumbersome and inconvenient to use.

[0005] Therefore, the present application proposes a benchmark for building construction measurement. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention provides a benchmark for building construction measurement, which solves the problems mentioned in the background technology.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A surveying pole for building construction includes a tripod, a through-hole formed on the top of the tripod, a mounting base mounted on the top of the tripod, a through-hole formed on the top of the mounting base connected to the through-hole, brackets symmetrically fixed to the inner sidewalls of the through-hole, horizontal rotating shafts rotatably mounted on both brackets, the two rotating shafts being located in the same axial direction, and a vertical pole body fixedly connected between opposite sides of the two rotating shafts;

[0009] A conical column is integrally formed at the bottom of the pole body, and a counterweight is installed on the pole body between the conical column and the opposite side of the rotating shaft. The center of gravity of the counterweight is located in the axial direction of the pole body. A positioning mechanism acting on the pole body is installed on the mounting seat, which is used to position or cancel the positioning of the pole body.

[0010] Further: the positioning mechanism includes a guide rod that is horizontal and movably passes through the mounting seat, the axial direction of the guide rod is parallel to the axial direction of the rotating shaft, one end of the guide rod extends into the through hole and is fixedly installed with a resistance plate, and a driving member acting on the resistance plate is installed on the mounting seat, which is used to make the resistance plate slide or stop sliding along the guide rod.

[0011] Furthermore: the driving member includes a driving rod that is horizontal and has a thread passing through the mounting seat, and one end of the driving rod extends into the through hole and is rotatably connected to the contact plate.

[0012] Furthermore: the counterweight block is movably sleeved on the outside of the benchmark body, and a fixing piece that can be connected to the benchmark body is installed on the counterweight block, which is used to fix or cancel the fixation between the counterweight block and the benchmark body.

[0013] Further: the fixing member includes:

[0014] There are two threaded rods, both of which are horizontal and symmetrically arranged along the axis of the benchmark body. The two threaded rods are respectively threaded through the two sides of the counterweight block and can form a conflict with the benchmark body.

[0015] Furthermore: a vertical guide column is fixed on the top of the tripod and on one side of the perforation, the mounting seat is slidably installed on the top of the tripod along the axial direction of the guide column, and a vertical adjustment rod is rotatably installed on the top of the tripod, and the adjustment rod thread passes through the mounting seat.

[0016] Furthermore: a groove is provided on one side of the benchmark body, and a scale is fixedly installed on the benchmark body and in the groove.

[0017] The utility model provides a benchmark for building construction measurement. Compared with the existing technology, it has the following advantages:

[0018] 1. When using this measuring pole, place the tripod on the ground and eliminate the positioning mechanism for the pole body. Since the center of gravity of the counterweight is located in the axis direction of the pole body, the weight of the counterweight can cause the pole body to rotate about two rotation axes, making the pole body vertical. This replaces the existing method of adjusting the tripod and using a level to measure and adjust the pole body vertically. This is simpler and easier for users to place and position the measuring pole.

[0019] 2. Through the design of the positioning mechanism, after the positioning of the measuring benchmark is completed, the positioning mechanism is used to position the benchmark body, thereby increasing the stability of the measuring benchmark during the measurement process;

[0020] 3. By arranging the counterweight block to be movably sleeved on the outside of the benchmark body, when the measuring benchmark is carried, the fixing between the counterweight block and the benchmark body by the fixing parts can be cancelled, so that the counterweight block can be disassembled, effectively avoiding the situation where the counterweight block affects the folding of the tripod, which is conducive to the carrying and use of the measuring benchmark.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. 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 ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] In order to solve the technical problems in the background technology, the following building construction measurement benchmark is provided:

[0031] Combine Figure 1-Figure 5 As shown, the utility model provides a benchmark for building construction measurement, including a tripod 1, a through hole 11 is opened on the top of the tripod 1, a mounting base 2 is installed on the top of the tripod 1, a through hole 21 connected to the through hole 11 is opened on the top of the mounting base 2, and brackets 22 are symmetrically fixed to the inner side walls of the through hole 21, and horizontal rotating shafts 23 are rotatably installed on the two brackets 22. The two rotating shafts 23 are located in the same axial direction, and a vertical benchmark body 3 is fixedly connected between the opposite sides of the two rotating shafts 23; a tapered column 4 is integrally formed with the bottom of the benchmark body 3, and a counterweight 5 is installed on the benchmark body 3 and between the opposite sides of the tapered column 4 and the rotating shaft 23. The center of gravity of the counterweight 5 is located in the axial direction of the benchmark body 3, and a positioning mechanism 6 acting on the benchmark body 3 is installed on the mounting base 2, which is used to position or cancel the positioning of the benchmark body 3.

[0032] When using the present measuring benchmark, the tripod 1 is placed on the ground, and the positioning of the benchmark body 3 by the positioning mechanism 6 is cancelled. Since the center of gravity of the counterweight 5 is located in the axial direction of the benchmark body 3, the benchmark body 3 can be rotated around the two rotating shafts 23 under the action of the gravity of the counterweight 5, so that the benchmark body 3 is vertical. This replaces the existing method of adjusting the tripod 1 and making the benchmark body 3 vertical with the help of a level ruler. It is simpler and convenient, thus making it easier for the user to place and position the present measuring benchmark. Through the design of the positioning mechanism 6, after the placement and positioning of the present measuring benchmark is completed, the benchmark body 3 is positioned by the positioning mechanism 6, thereby increasing the stability of the present measuring benchmark during the measurement process.

[0033] Example 2

[0034] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following content:

[0035] In this embodiment, the positioning mechanism 6 includes a guide rod 61 that is horizontal and movably passes through the mounting seat 2. The axial direction of the guide rod 61 is parallel to the axial direction of the rotating shaft 23. One end of the guide rod 61 extends into the through hole 21 and is fixedly installed with a resistance plate 62. A driving member 63 that acts on the resistance plate 62 is installed on the mounting seat 2, which is used to make the resistance plate 62 slide or stop sliding along the guide rod 61. When in use, the resistance plate 62 is displaced along the guide rod 61 toward the benchmark body 3 by the driving member 63, so that the resistance plate 62 forms a resistance with the benchmark body 3, and the benchmark body 3 can be positioned by the resistance plate 62. Conversely, the resistance plate 62 is displaced along the guide rod 61 away from the benchmark body 3 by the driving member 63, so that the resistance plate 62 does not contact the benchmark body 3, and the positioning of the benchmark body 3 can be cancelled.

[0036] In this embodiment, the driving member 63 includes a driving rod 631 that is horizontal and has a thread passing through the mounting seat 2. One end of the driving rod 631 extends into the through hole 21 and is rotatably connected to the resistance plate 62. When in use, a force is applied to the driving rod 631 to rotate it on the mounting seat 2, and the driving rod 631 moves spirally along the mounting seat 2. Since the driving rod 631 is rotatably connected to the resistance plate 62, at this time, the driving rod 631 and the resistance plate 62 rotate, so that the resistance plate 62 can slide along the guide rod 61. Since the threaded connection between the driving rod 631 and the mounting seat 2 is self-locking, the position of the resistance plate 62 can be fixed without rotating the driving rod 631, which is easy to operate.

[0037] In this embodiment, the counterweight 5 is movably mounted on the outside of the benchmark body 3, and a fixing part 7 that can be connected to the benchmark body 3 is installed on the counterweight 5, which is used to fix or cancel the fixation between the counterweight 5 and the benchmark body 3. By setting the counterweight 5 to be movably mounted on the outside of the benchmark body 3, when the measuring benchmark is carried, the fixation between the counterweight 5 and the benchmark body 3 by the fixing part 7 can be canceled, so that the counterweight 5 can be disassembled, effectively avoiding the counterweight 5 affecting the folding of the tripod 1, which is conducive to the carrying and use of the measuring benchmark.

[0038] Example 3

[0039] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following content:

[0040] In this embodiment, the fixing member 7 includes: two threaded rods 71, both of which are horizontal and symmetrically arranged along the axial direction of the benchmark body 3. The two threaded rods 71 ​​are respectively threaded through the two sides of the counterweight block 5 and can form a conflict with the benchmark body 3. When in use, the counterweight block 5 is sleeved on the outside of the benchmark body 3, and a force is applied to the two threaded rods 71 ​​to rotate the two threaded rods 71 ​​on the counterweight block 5, so that the two threaded rods 71 ​​spirally move closer to each other on the counterweight block 5, so that the two threaded rods 71 ​​form a conflict with the benchmark body 3, and the counterweight block 5 and the benchmark body 3 can be fixed. Conversely, the two threaded rods 71 ​​are rotated in the opposite direction so that the two threaded rods 71 ​​are no longer in contact with the benchmark body 3, and the fixation between the counterweight block 5 and the benchmark body 3 can be cancelled, which is simple to operate.

[0041] In this embodiment, a vertical guide column 12 is fixed to the top of the tripod 1 and located on one side of the through-hole 11. The mounting seat 2 is slidably installed on the top of the tripod 1 along the axial direction of the guide column 12. A vertical adjusting rod 13 is rotatably installed on the top of the tripod 1, and the adjusting rod 13 is threaded through the mounting seat 2. By setting the mounting seat 2 to be slidably installed on the top of the tripod 1 along the axial direction of the guide column 12, when the ground is an inclined surface, the adjusting rod 13 can be rotated to make the mounting seat 2 slide along the guide column 12 to adjust the height position of the mounting seat 2, thereby adjusting the height position of the benchmark body 3 and the height position of the tapered column 4. When the benchmark body 3 is vertical under the action of the gravity of the counterweight 5, the adjusting rod 13 can be rotated to make the tapered column 4 contact with the ground, which is convenient for users to use this measuring benchmark for construction measurement operations.

[0042] In this embodiment, a groove 31 is provided on one side of the benchmark body 3, and a scale 32 is fixedly installed on the benchmark body 3 and in the groove 31. By setting the groove 31, the scale 32 is fixedly installed in the groove 31, thereby effectively preventing the user from wearing out the scale lines on the scale 32 when holding the benchmark body 3 during use of this measuring benchmark.
