Description

Technical Field

[0001] This utility model relates to a benchmark, specifically a benchmark for measuring building construction, and belongs to the field of building construction technology. Background Technology

[0002] A surveying pole is a widely used tool in building construction surveying. In leveling, the pole serves as a marker for measurement points and a basis for elevation measurement. When pouring cement mortar flooring, construction workers place a laser measuring instrument in a stable position. The instrument emits a horizontal laser beam as a reference surface for leveling. Then, the workers hold the pole and stand it vertically at the location to be measured or leveled. The laser receiver on the pole receives the laser signal emitted by the laser measuring instrument, thereby obtaining the elevation difference between the point and a known elevation point and calculating the elevation of the point. This completes the leveling work and ensures that the overall flatness of the cement mortar floor is within a certain range.

[0003] However, when pouring cement mortar flooring, workers need to frequently and repeatedly place the markers on the cement mortar. Since cement mortar has a certain fluidity, it is easy for cement mortar to splash onto the part of the markers near the ground during the pouring and spreading process, which will cover the scale lines on the markers. This will reduce the clarity of the scale lines, making it difficult to accurately distinguish the scale values. Furthermore, frequent or improper cleaning will cause the ink or coating on the scale lines to gradually peel off or fade, thereby reducing the durability of the scale lines. Utility Model Content

[0004] The purpose of this utility model is to provide a measuring pole for building construction in order to solve the above problems. By installing a transparent protective cover, cement mortar and other substances can be prevented from directly contacting the pole body, reducing the risk of damage to the pole body, keeping the scale lines clear, and thus extending the service life of the pole body.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a surveying pole for building construction includes a base, a protrusion fixedly connected to the base, a pole body fixedly connected to the protrusion, a protective structure installed on the pole body, the protective structure including a transparent protective cover, the transparent protective cover slidably connected to the pole body, the bottom end of the transparent protective cover engaging with the protrusion, a knob rotatably connected to the transparent protective cover, the end of the knob threadedly connected to the pole body, and a laser receiver installed on the pole body via an installation structure.

[0006] Preferably, the protrusion has a rectangular structure as a whole, the cross-section of the protrusion has a "U" shaped structure, and the transparent protective cover has a rectangular structure.

[0007] Preferably, a rubber pad is installed on the inner wall of the transparent protective cover, and the rubber pad abuts against the marker body.

[0008] Preferably, the mounting structure includes a first clamping plate, one side of the marker body abuts against the first clamping plate, a laser receiver is mounted on the first clamping plate, the other side of the marker body abuts against a second clamping plate, a sliding plate is fixedly connected to the second clamping plate, and the sliding plate is slidably connected to the first clamping plate.

[0009] Preferably, a screw is rotatably connected to the first clamping plate, and the sliding plate is threadedly connected to the screw.

[0010] Preferably, the first clamping plate has an "L" shaped cross-section, and anti-slip pads are installed on the inner walls of both the first and second clamping plates.

[0011] Preferably, an extension rod is slidably connected within the main body of the marker, and both the main body of the marker and the extension rod are provided with scale lines.

[0012] Preferably, the extension rod is equipped with two locking blocks, and a locking groove is provided at the top of the pole body, with one of the locking blocks engaging with the locking groove.

[0013] Preferably, a spring is fixedly connected between the locking block and the extension rod, with one end of the spring fixedly connected to the extension rod and the other end of the spring fixedly connected to the locking block.

[0014] The beneficial effects of this utility model are as follows: a protrusion is fixedly connected to the base, a marker body is fixedly connected to the protrusion, and a transparent protective cover is slidably connected to the marker body. By installing the transparent protective cover, cement mortar and other substances can be prevented from directly contacting the marker body, keeping the scale lines clear, reducing the risk of damage to the marker body, and thus extending the service life of the marker body. The bottom end of the transparent protective cover engages with the protrusion, and a knob is rotatably connected to the transparent protective cover.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 As shown, a surveying pole for building construction includes a base 1, a protrusion 2 fixedly connected to the base 1, a pole body 3 fixedly connected to the protrusion 2, a protective structure 4 installed on the pole body 3, the protective structure 4 including a transparent protective cover 401, the transparent protective cover 401 slidably connected to the pole body 3, the bottom end of the transparent protective cover 401 engaging with the protrusion 2, a knob 403 rotatably connected to the transparent protective cover 401, the end of the knob 403 threadedly connected to the pole body 3, the protrusion 2 having a rectangular structure overall, the cross-section of the protrusion 2 having a "U" shaped structure, the transparent protective cover 401 having a rectangular structure, and a laser receiver 6 installed on the pole body 3 via an installation structure 5.

[0025] As a technical optimization of this utility model, a rubber pad 402 is installed on the inner wall of the transparent protective cover 401. The rubber pad 402 abuts against the marker body 3. The rubber pad 402 installed on the inner wall of the transparent protective cover 401 abuts against the marker body 3, which helps to prevent fine particles such as mortar from entering the interior of the transparent protective cover 401 from the gaps, thereby further improving the protective effect of the transparent protective cover 401 on the marker body 3 and the scale line 11.

[0026] As a technical optimization of this utility model, the installation structure 5 includes a first clamping plate 501. One side of the marker body 3 abuts against the first clamping plate 501, and a laser receiver 6 is installed on the first clamping plate 501. The other side of the marker body 3 abuts against a second clamping plate 502, and a sliding plate 504 is fixedly connected to the second clamping plate 502. The sliding plate 504 is slidably connected to the first clamping plate 501, and a screw 503 is rotatably connected to the first clamping plate 501. The sliding plate 504 is threadedly connected to the screw 503. The screw 503 drives the sliding plate 504 to slide into the first clamping plate 501, thereby causing the sliding plate 504 to drive the second clamping plate 502 to cooperate with the first clamping plate 501 to tighten the marker body 3, thereby quickly completing the installation of the laser receiver 6, making the installation and removal of the laser receiver 6 flexible and convenient.

[0027] As a technical optimization of this utility model, the cross-section of the first clamping plate 501 is L-shaped, which makes the first clamping plate 501 fit well with the pole body 3. Anti-slip pads 505 are installed on the inner walls of the first clamping plate 501 and the second clamping plate 502. The anti-slip pads 505 installed on the inner walls of the first clamping plate 501 and the second clamping plate 502 increase the friction, ensuring that the laser receiver 6 is installed firmly and is not easy to shake or slip off, so that the laser receiver 6 can be installed more stably on the pole body 3.

[0028] As a technical optimization of this utility model, an extension rod 7 is slidably connected inside the pole body 3. Both the pole body 3 and the extension rod 7 are provided with scale lines 11. By installing the extension rod 7, the measurement range of the pole body 3 can be flexibly adjusted. Two locking blocks 8 are installed on the extension rod 7. A locking groove 10 is opened at the top of the pole body 3. One of the locking blocks engages with the locking groove 10. A spring 9 is fixedly connected between the locking block 8 and the extension rod 7. One end of the spring 9 is fixedly connected to the extension rod 7, and the other end of the spring 9 is fixedly connected to the locking block 8. The spring 9 drives the locking block 8 to engage with the locking groove 10 on the pole body 3 to limit the extension rod 7.

[0029] In use, this utility model first installs a protective structure 4 to protect the marker body 3 and the scale line 11 near the ground. During installation, the transparent protective cover 401 is slid down along the marker body 3 until the bottom end of the transparent protective cover 401 engages with the protrusion 2. At this point, the transparent protective cover 401 is initially fixed to the marker body 3. Next, the knob 403 on the transparent protective cover 401 is rotated to connect the end of the knob 403 to the marker body 3 via a thread, thereby further securing the transparent protective cover 401 and ensuring its stability. 1. Securely installed on the marker body 3, the transparent protective cover 401 effectively resists the erosion of the marker body 3 by external substances such as cement mortar. The transparent protective cover 401 is made of transparent material and does not affect the reading of the scale line 11 during operation. When installing the laser receiver 6, firstly, the first clamping plate 501 and the second clamping plate 502 are brought closer to the marker body 3, positioning the marker body 3 in the groove between the two clamping plates. Then, the first clamping plate 501 is placed against one side of the marker body 3. Next, the screw 503 is rotated to screw the receiver 6. The second clamping plate 502 is driven to move closer to the first clamping plate 501, thereby clamping the two clamping plates together to quickly complete the installation of the laser receiver 6. The distance between the first clamping plate 501 and the second clamping plate 502 can be adjusted according to the different sizes of the pole body 3, allowing the laser receiver 6 to be securely installed on pole bodies 3 of varying thicknesses. When the pole length needs to be increased to adapt to different measurement scenarios, one hand presses a locking block 8 at the top of the extension rod 7 into the pole body 3, causing the locking block 8 to move inwards. The extension rod 7 no longer engages with the slot 10 at the top of the pole body 3. At the same time, the locking block 8 drives the spring 9 to compress. Simultaneously, the other hand is used to pull the extension rod 7 outward from the pole body 3, causing the extension rod 7 to slide outward from the pole body 3. At this time, the locking block 8 at the bottom of the extension rod 7 drives the spring 9 connected to the locking block 8 to remain compressed and continue to pull the extension rod 7 outward. When the locking block 8 at the bottom of the extension rod 7 aligns with the slot 10 on the pole body 3, the spring 9 resets and drives the locking block 8 to engage with the slot 10, thereby limiting the extension rod 7.
