Description

Technical Field

[0001] This utility model belongs to the field of static leveling instrument technology, specifically relating to a leveling instrument used for monitoring the settlement of formwork in building engineering. Background Technology

[0002] In the field of building construction, concrete pouring is a crucial process in structural forming. During pouring, the formwork system (including support frames, panels, etc.) bears the enormous fluid pressure of the freshly mixed concrete, construction loads, and its own weight. If the formwork or support system experiences settlement, deformation, or displacement exceeding the design allowable range, it will directly lead to elevation errors and component dimensional deviations in the poured concrete structure, and may even cause quality and safety accidents such as formwork bulging and bursting, seriously affecting structural safety, functionality, and construction progress. Therefore, real-time and accurate settlement monitoring of formwork during the pouring stage is a core technical aspect to ensure construction quality and safety.

[0003] In existing technologies for monitoring formwork settlement, such as the formwork support frame foundation settlement monitoring device disclosed in Chinese Patent Publication No. CN208313280U, several hydrostatic levels are connected in series to monitor the settlement of the formwork foundation. The structure and monitoring principle of the hydrostatic level are similar to those of a hydrostatic level for settlement monitoring disclosed in Chinese Patent Publication No. CN220356359U, which judges settlement by the height change of the liquid level float. However, during the construction process, the formwork support structure vibrates, causing the liquid to slosh and reducing the stability of the liquid level float, thus affecting the accuracy of the monitoring results.

[0004] Therefore, it is necessary to propose a level instrument for monitoring the settlement of formwork in building engineering to solve the above problems. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a level for monitoring the settlement of formwork in building engineering, so as to solve the problem that the vibration of the formwork support structure caused by the construction process affects the accuracy of the monitoring results in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a level instrument for monitoring the settlement of formwork in building engineering, including a liquid level cylinder. A measuring rod is axially fixedly connected inside the liquid level cylinder. An electronic chamber is connected to the end of the measuring rod extending out of the liquid level cylinder. An inner cylinder is fixedly installed inside the liquid level cylinder. A notch is provided between the inner cylinder and the bottom wall of the liquid level cylinder to allow communication between the inner cylinder and the liquid level cylinder. A float ball that can slide along the inside of the inner cylinder is slidably sleeved on the measuring rod. A first annular gap is provided between the float ball and the inner wall of the inner cylinder. The width of the first annular gap is 1mm to 2mm.

[0008] Furthermore, a second annular gap is provided between the outer wall of the inner cylinder and the inner wall of the liquid level cylinder, and the width of the second annular gap is greater than the width of the first annular gap.

[0009] Furthermore, both the inner cylinder sidewall and the liquid level cylinder sidewall are provided with vent holes.

[0010] Furthermore, a cap is inserted and fixed to the top of the liquid level cylinder, the inner cylinder is detachably connected to the cap, and the cap is provided with a through hole for the measuring rod to pass through.

[0011] Furthermore, a base is fixedly sleeved at the bottom of the liquid level cylinder, and a pipe interface communicating with the liquid level cylinder is radially provided on the base. The pipe interface is used to connect pipes to connect several liquid level cylinders in series.

[0012] Furthermore, a filter screen is fixedly connected within the second annular gap.

[0013] Furthermore, a retaining ring for supporting the filter screen is fixedly provided on the inner wall of the liquid level cylinder, and a limiting ring is fixedly provided on the outer wall of the inner cylinder. The retaining ring and the limiting ring cooperate to clamp and fix the filter screen.

[0014] Furthermore, the bottom wall of the inner cylinder is conical, so that impurities or bubbles can rise along the conical surface to the space between the liquid level cylinder and the inner cylinder.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention, by setting an inner cylinder, creates a first annular gap between the inner cylinder and the float, generating significant viscous resistance to the vertical flow of the liquid. When external liquid generates waves due to vibration, the energy of the waves is greatly weakened as they pass through the narrow gap, keeping the liquid surface inside the inner cylinder highly stable. This effectively mitigates the impact of liquid disturbances on the stability of the float during construction. Furthermore, the inner cylinder can shield the float from direct impacts from external turbulence or bubbles, placing it in a relatively stable liquid environment, minimizing the impact of process disturbances on measurement.

[0017] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the following drawings are provided for illustration:

[0020] Figure 2 This is an embodiment of the present utility model. Figure 1 A magnified view of part A in the middle.

[0021] The following are marked in the attached diagram: liquid level cylinder 1, second annular gap 101, filter screen 102, retaining ring 103, measuring rod 2, electronic chamber 3, inner cylinder 4, first annular gap 401, limiting ring 402, float ball 5, vent hole 6, cover 7, base 8, pipe interface 801. Detailed Implementation

[0022] like Figures 1-2 As shown, a level instrument for monitoring the settlement of formwork in building engineering includes: a liquid level cylinder 1, a measuring rod 2 axially fixedly connected to the liquid level cylinder 1, an electronic chamber 3 connected to the end of the measuring rod 2 extending out of the liquid level cylinder 1, an inner cylinder 4 fixedly disposed inside the liquid level cylinder 1, a notch provided between the inner cylinder 4 and the bottom wall of the liquid level cylinder 1 to allow communication between the inner cylinder 4 and the liquid level cylinder 1, a float 5 slidably sleeved on the measuring rod 2 and capable of sliding along the inside of the inner cylinder 4, a first annular gap 401 provided between the float 5 and the inner wall of the inner cylinder 4, the width of the first annular gap 401 being 1mm~2mm.

[0023] In this scheme, when using the level instrument for template settlement monitoring, the level instrument is fixedly installed at several monitoring points. These level instruments are connected in series via pipes, similar to the installation method described in Chinese Patent Publication No. CN208313280U, which discloses a template support frame foundation settlement monitoring device. Settlement is determined by observing the height of the float 5. The electronic chamber 3 contains an excitation module. The electronic chamber 3, in conjunction with the measuring rod 2, can record the height of the float 5. The principle is described in Chinese Patent Publication No. CN220356359U, which discloses a device for settlement monitoring. The hydrostatic level used for monitoring has been publicly disclosed and will not be described in detail here. This scheme, by setting up an inner cylinder 4, creates a large viscous resistance to the vertical flow of liquid through the first annular gap 401 between the inner cylinder 4 and the float 5. When the external liquid generates waves due to vibration, the energy of the waves is greatly weakened when passing through the narrow gap, so that the liquid surface inside the inner cylinder 4 remains highly stable, effectively preventing the impact of liquid disturbance on the stability of the float 5 during construction. Furthermore, the inner cylinder 4 can shield the float 5 from the direct impact of external turbulence or bubbles, keeping it in a relatively stable liquid environment, and minimizing the impact of process disturbance on the measurement.

[0024] In one embodiment of the present invention, a second annular gap 101 is provided between the outer wall of the inner cylinder 4 and the inner wall of the liquid level cylinder 1, and the width of the second annular gap 101 is greater than the width of the first annular gap 401.

[0025] In this solution, by increasing the width of the second annular gap 101, the fluid resistance of liquid flowing into the space where the second annular gap 101 is located can be reduced, so as to ensure that the float ball follows the liquid level change in a timely manner; and dirt can be deposited in the second annular area 101 between the inner cylinder 4 and the liquid level cylinder 1, and is less likely to come into contact with the float ball 5, thereby reducing the risk of dirt getting stuck on the float ball 5.

[0026] In one embodiment of this utility model, both the inner cylinder 4 and the liquid level cylinder 1 are provided with vent holes 6.

[0027] In this scheme, the pressure is balanced by setting the vent hole 6, ensuring that the liquid level in the inner cylinder 4 is consistent with the liquid level between the liquid level cylinder 1 and the inner cylinder 4, thereby reducing the retention of air bubbles.

[0028] In one embodiment of this utility model, a cap 7 is inserted and fixed to the top of the liquid level cylinder 1, the inner cylinder 4 is detachably connected to the cap 7, and the cap 7 is provided with a through hole for the measuring rod to pass through.

[0029] In this solution, the inner cylinder 4 and the cover 7 can be detachably connected by means of plug-in fixing, threaded connection fixing, bolt fixing, etc. The detachable method is a conventional technical means in this field and will not be described in detail here. This solution uses a detachable connection to facilitate the cleaning or replacement of the inner cylinder 4. In addition, in a highly stable construction environment with less vibration, settlement monitoring can also be achieved by removing the inner cylinder 4, thereby reducing costs.

[0030] In one embodiment of the present invention, a base 8 is fixedly sleeved at the bottom of the liquid level cylinder 1, and a pipe interface 801 communicating with the liquid level cylinder 1 is radially provided on the base 8. The pipe interface 801 is used to connect pipes to connect several liquid level cylinders 1 in series to form a communicating vessel.

[0031] In one embodiment of the present invention, a filter screen 102 is fixedly connected inside the second annular gap 101.

[0032] In this design, when liquid is injected into the liquid level cylinder 1, the liquid level is kept close to the bottom of the filter screen 102. When the liquid vibrates and shakes, the filter screen 102 can break up the large-scale liquid sloshing and waves in the second annular gap 101 and convert them into small-scale turbulence, thereby quickly dissipating vibration energy and smoothing out liquid surface fluctuations. At the same time, the filter screen 102 can be made of mesh material, which can adhere to impurities in the liquid and reduce the inflow of external impurities into the liquid from the vent hole 6.

[0033] In one embodiment of this utility model, such as Figure 2The inner wall of the liquid level cylinder 1 is fixedly provided with a retaining ring 103 for supporting the filter screen 102, and the outer wall of the inner cylinder 4 is fixedly provided with a limiting ring 402. The retaining ring 103 and the limiting ring 402 cooperate to clamp and fix the filter screen 102.

[0034] In this design, when assembling the level instrument, the filter screen 102 is first inserted along the inner wall of the level cylinder 1 until it rests on the retaining ring 103. Then, after fixing the inner cylinder 4 to the cover 7, the float 5 is fitted onto the measuring rod 2. Next, the level cylinder 1 is inserted into the cover 7 so that the limiting ring 402 rests on top of the filter screen 102 to clamp and fix it. Finally, the base 8 is fixed to the bottom wall of the level cylinder 1. This design facilitates the installation and removal of the filter screen 102 through the cooperation of the retaining ring 103 and the limiting ring 402.

[0035] In one embodiment of this utility model, the bottom wall of the inner cylinder 4 is conical, so that impurities or bubbles can rise along the conical surface to the space between the liquid level cylinder and the inner cylinder.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
