Description

Technical Field

[0001] This invention relates to the field of V-shaped column structure technology, specifically to a V-shaped column protective structure and a V-shaped column protection method. Background Technology

[0002] During the construction of the steel canopy, it was divided into a roof canopy and a facade canopy. The roof canopy was further divided into n hoisting structural units and n intermediate closure units. The hoisting structural units were further divided into a balancing zone truss structure segment, an inner ring truss structure segment, and a canopy area truss structure segment. After the main concrete structure was completed, construction of the facade canopy began. Simultaneously, temporary support frames 2b were installed on the outer and inner sides of the grandstand structure within the site. The balancing zone truss structure segment, the canopy area truss structure segment, and the inner ring truss structure segment were all installed using the integral hoisting method. The facade canopy and intermediate closure units were installed using the high-altitude assembly method. Lifting equipment was used to fill in the gaps between the intermediate closure units and the hoisting structural units, completing the construction.

[0003] However, during the construction of the aforementioned facade canopy, V-shaped columns 1a are used, and temporary support frames 2b are installed below both ends of the V-shaped columns to support them and ensure their safety. When the steel canopy is very large, the number of V-shaped columns 1a required will also be large. For example, when there are 28 V-shaped columns 1a, the corresponding number of temporary support frames 2b is 56. However, before the roof canopy within the steel canopy is closed, a self-balancing system cannot be formed. Therefore, the temporary support frames 2b cannot be removed until the installation and unloading are completed, resulting in a large number of temporary support frames 2b being occupied.

[0004] To address the issue of the temporary support frame 2b being heavily occupied, a top-tying method (i.e., connecting the tops of the two extended arms of the V-shaped column with steel pipes) was adopted to stabilize the V-shaped column 1a. While this method can stabilize the V-shaped column 1a to some extent, it is impossible to know the stress and displacement at both ends of the V-shaped column 1a when it is under unilateral stress, until a large deformation occurs, posing a significant safety risk.

[0005] In view of the above shortcomings, it is necessary to design a V-shaped column protection structure and a V-shaped column protection method. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is that the method of stabilizing V-shaped columns by top bracing can only be detected after a large deformation occurs, which poses a great safety risk. Thus, the present invention provides a V-shaped column protection structure and a V-shaped column protection method.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0008] A V-shaped column protective structure includes a V-shaped column, a tie structure, and a sensor. The V-shaped column includes a base and two extension arms extending from the base. The two ends of the tie structure are respectively connected to the two extension arms. The sensor is mounted on the tie structure to detect the tension signal and / or deformation displacement signal of the tie structure.

[0009] Furthermore, the tie structure includes a first tie rod, a second tie rod, and a connecting element. The outer ends of the first tie rod and the second tie rod are respectively connected to the two extension arms, and the inner ends of the first tie rod and the second tie rod are respectively connected to the two ends of the connecting element.

[0010] Furthermore, the length of the connecting element is 0.8m to 1.2m.

[0011] Furthermore, the connecting element is a steel wire rope or steel strand, and / or the first tie rod and the second tie rod are steel pipes.

[0012] Furthermore, the first pull rod and the second pull rod are respectively connected to the ends of the extension arm away from the base.

[0013] Furthermore, each of the two extension arms has a protrusion at its end, and the first pull rod and / or the second pull rod is connected to the corresponding protrusion.

[0014] Furthermore, the first pull rod and / or the second pull rod are hinged to the extension arm; or, the first pull rod and / or the second pull rod are rigidly connected to the extension arm.

[0015] Furthermore, the center lines of the first pull rod, the connecting element, and the second pull rod are located on the same straight line. Preferably, the lengths of the first pull rod and the second pull rod are equal.

[0016] Furthermore, it also includes an analysis module and an alarm module; the analysis module receives and analyzes the tension signal and / or deformation displacement signal detected by the sensor, and when it is determined that the tension in the connecting element exceeds a preset tension value and / or the displacement exceeds a preset displacement, the analysis module sends an alarm command to the alarm module, and the alarm module issues an alarm.

[0017] The technical solution of the present invention has the following advantages:

[0018] 1. The V-shaped column protection structure provided by the present invention includes a V-shaped column, a tie structure, and a sensor. The V-shaped column includes a base and two extension arms extending from the base. The two ends of the tie structure are respectively connected to the two extension arms. The sensor is installed on the tie structure to detect the tension signal and / or deformation displacement signal of the tie structure. The tension signal and / or deformation displacement signal of the tie structure detected by the sensor reflects the stress condition of the extension arms of the V-shaped column, which can promptly detect V-shaped columns with significant risks and protect them to ensure construction quality and safety.

[0019] 2. The V-shaped column protection structure provided by the present invention has a connecting element length of 0.8m to 1.2m. This facilitates the installation of the sensor without significantly affecting the binding effect of the tie structure on the two extension arms.

[0020] 3. The V-shaped column protective structure provided by the present invention uses steel wire rope or steel strand as the connecting element. On the one hand, due to its smaller diameter, it can better reflect the deformation of the extension arm after being subjected to force compared with steel pipe with a larger diameter. On the other hand, due to its high tensile strength, it can better tie the two extension arms of the V-shaped column together and prevent the two extension arms from opening excessively outward.

[0021] 4. The V-shaped column protection structure provided by the present invention has a first tie rod and a second tie rod respectively connected to the end of the extension arm. The end of the extension arm is far away from the base. Since the end of the extension arm is the position with the greatest deformation, the risk can be detected early, and the V-shaped column at risk can be protected early.

[0022] 5. In the V-shaped column protection structure provided by the present invention, the center lines of the first tie rod, the connecting element and the second tie rod are located on the same straight line. This facilitates the acquisition of tension signals and deformation displacement signals by the sensor and avoids interference from torque signals generated by the first tie rod, the second tie rod and the connecting element.

[0023] A method for protecting a V-shaped post includes the following steps:

[0024] Detect tension signals and / or deformation displacement signals in the tie structure;

[0025] Determine whether the tension in the tie structure exceeds a preset tension value, and / or whether the deformation displacement of the tie structure exceeds a preset displacement value;

[0026] When the tension exceeds the preset tension value and / or the deformation displacement exceeds the preset displacement value, the V-shaped column where the tie structure is located is protected.

[0027] The technical solution of the present invention has the following advantages:

[0028] The V-shaped column protection method provided by this invention reflects the stress condition of the V-shaped column through the tension and / or deformation displacement signals of the tie structure, and protects the V-shaped column at risk in a timely manner, thereby ensuring the safety of the V-shaped column and thus ensuring construction quality and construction safety.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] like Figure 2 and Figure 3 As shown, this embodiment provides a V-shaped column protection structure, including a V-shaped column 1, a tie structure, and a sensor 5.

[0040] First, it needs to be emphasized that the V-shaped column 1 is not an ordinary V-shaped structure, unlike the V-shaped structures seen in everyday items such as slingshots. In this embodiment, the V-shaped column 1 serves as a construction fulcrum for the outer ring steel canopy A of the steel structure; it can be understood as a supporting structure used in the construction of large buildings. Figure 2 As shown, the outer ring steel canopy A of the steel structure includes a two-story platform A2 and a grandstand seating area A1.

[0041] The V-shaped column 1 includes a base 11 and two extension arms 12 extending from the base 11. The base 11 is a steel pipe structure and is typically fixed to the ground for initial fixation of the V-shaped column 1. The extension arms 12 are typically made of the same material as the base 11, also using a steel pipe structure. The extension arms 12 are welded together with the base 11. The top of the extension arms 12 is connected to a truss unit (unlabeled) to support the truss unit.

[0042] The two ends of the tie structure are connected to the two extension arms 12 respectively, so as to tie the two extension arms 12 and prevent the two extension arms 12 from opening excessively outward. The tie structure includes a first tie rod 2, a second tie rod 3, and a connecting element 4.

[0043] Both the first tie rod 2 and the second tie rod 3 are steel pipes. The first tie rod 2 and the second tie rod 3 are of equal length. The outer ends of the first tie rod 2 and the second tie rod 3 are respectively connected to the two extension arms 12. Preferably, the first tie rod 2 and the second tie rod 3 are respectively connected to the ends of the extension arms 12, and the ends of the extension arms 12 are far away from the base 11. Because the ends are the positions where the V-shaped column 1 deforms the most during use, connecting the first tie rod 2 and the second tie rod 3 to the ends of the extension arms 12 can detect risks early and take preventive measures early. Specifically, the ends of the two extension arms 12 are respectively provided with protrusions 121, and the first tie rod 2 and the second tie rod 3 are connected to the corresponding protrusions 121. The inner ends of the first tie rod 2 and the second tie rod 3 are respectively connected to the two ends of the connecting element 4. Here, the inner end is the end near the vertical center line of the V-shaped column 1, and the outer end is the end away from the vertical center line of the V-shaped column 1. The first tie rod 2 and the second tie rod 3 are respectively hinged to the two extension arms 12. Of course, the first pull rod 2 and the second pull rod 3 can also be rigidly connected to the extension arm 12 respectively.

[0044] The connecting element 4 is made of a material with small deformation and high tensile strength, such as steel wire rope or steel strand. On the one hand, because the diameter of the steel wire rope or steel strand is relatively small, it can better reflect the deformation of the extension arm 12 under force compared to the steel pipe with a larger diameter. On the other hand, because of its high tensile strength, it can ensure the binding effect of the two extension arms 12 of the V-shaped column 1 and prevent the two extension arms 12 from opening excessively outward.

[0045] The length of the connecting element 4 is 0.8m to 1.2m, which facilitates the installation of the sensor 5 without significantly affecting the connection effect of the two extension arms 12.

[0046] After the first tie rod 2, the second tie rod 3, and the connecting element 4 are connected to the V-shaped column 1, the center lines of the first tie rod 2, the connecting element 4, and the second tie rod 3 are on the same straight line. At the construction site, the center lines of the first tie rod 2, the connecting element 4, and the second tie rod 3 are on the same horizontal line. This facilitates the acquisition of tension signals and deformation displacement signals by the sensor 5 and avoids torque signal interference between the first tie rod 2, the second tie rod 3, and the connecting element 4.

[0047] Sensor 5 is mounted on connecting element 4 to detect tension and deformation displacement signals in connecting element 4. Preferably, sensor 5 is a sensor that monitors both tension and displacement. Of course, sensor 5 may also detect only one of the tension and deformation displacement signals.

[0048] The V-shaped column protection structure also includes an analysis module (not shown) and an alarm module (not shown).

[0049] The following describes the method of protecting the V-shaped column 1 using the V-shaped column protective structure in this embodiment:

[0050] The base 11 of the V-shaped column 1 is fixed to the ground, and the top end of the extension arm 12 is connected to the truss unit.

[0051] Connect the outer ends of the first pull rod 2 and the second pull rod 3 to the two extension arms 12 of the V-shaped column 1 respectively, connect the two ends of the connecting element 4 to the inner ends of the first pull rod 2 and the second pull rod 3 respectively, and install the sensor 5 on the connecting element 4.

[0052] Connect sensor 5 electrically to the analysis module, and connect the analysis module electrically to the alarm module.

[0053] Sensor 5 detects the tension signal and deformation displacement signal in the connecting element 4 in real time. When the external force on both extension arms 12 increases, both extension arms 12 expand outward, the tension in the connecting element 4 increases, and sensor 5 can detect the directional tension signal and deformation displacement of the connecting element 4. Alternatively, when the external force on one extension arm 12 increases and this extension arm 12 expands outward relative to the other extension arm 12, the tension in the connecting element 4 also increases, and the connecting element 4 will undergo corresponding deformation displacement. Sensor 5 will be able to detect the corresponding directional tension signal and deformation displacement signal.

[0054] The analysis module determines whether the tension in the connecting element 4 exceeds the preset tension value and whether the deformation displacement of the connecting element 4 exceeds the preset displacement value.

[0055] When the tension exceeds the preset tension value and the deformation displacement exceeds the preset displacement value, the analysis module sends an alarm command to the alarm module, which then issues an alarm to remind construction personnel to take timely and targeted protection measures for the V-shaped column 1, ensuring construction quality and safety.

[0056] It should be noted that, due to the large number of V-shaped columns 1 used during the construction of the outer ring steel canopy A, sensors 5 need to be numbered to quickly determine which V-shaped column 1 requires targeted protection. The tension and deformation displacement signals sent by sensors 5 to the analysis module also need to display the sensor number. Alternatively, sensors 5 can also detect only one of the tension and deformation displacement signals, but the reliability is not as good as simultaneously detecting both signals.

[0057] In summary, in this embodiment, the tension signal and / or deformation displacement signal of the connecting element 4 detected by the sensor 5 are used to reflect the stress condition of the extension arm 12 of the V-shaped column 1. This allows for the timely detection of V-shaped columns 1 with significant risks and the protection of these columns, thereby ensuring construction quality and safety.

[0058] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
