Description

Technical Field

[0002] With the continuous updating and iteration of construction technology in the construction industry, the optimization of space utilization design has become the main demand of the owners. For this reason, tall structures often appear in the construction process, and most of the tall structures are projects with high risks exceeding a certain scale.

[0003] For projects with higher risks, the construction of this part of the project must be approved by experts before construction can be carried out. In civil construction, projects with higher risks exceeding a certain scale are mainly concentrated in the installation and removal of formwork for tall structures. According to the construction process, after the installation of the formwork for tall structures is accepted, real-time deformation monitoring should be carried out during the loading process. If the deformation exceeds the requirements of the demonstration plan, the emergency procedure should be initiated in a timely manner according to the emergency plan.

[0041] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant inventions, rather than to limit the inventions. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] Reference Figures 1 to 5 As shown, the present invention provides a formwork deformation monitoring device for a tall building structure, including: a cap, a support, and a transmission rod 3.

[0044] The support is provided with a containing box 11. In this embodiment, the containing box is a cubic steel box. The containing box has six sides, wherein three side inner walls and the top inner wall of the containing box 11 are respectively provided with through holes. The through holes of the two adjacent side inner walls and the top inner wall are respectively connected with sleeves 12. A dial 13 is installed at one end of the sleeve 12 away from the containing box 11.

[0045] The dial is circular, and the shape and size of the dial are adapted to the outer diameter and size of the sleeve. The dial is marked with a plurality of concentric circle scale lines. The plurality of concentric circle scale lines are arranged at equal intervals, and the centers of the plurality of concentric circle scale lines coincide with the center of the dial.

[0046] The support is movably mounted on the bottom inner wall of the accommodating box 11 through a support spring 21. In this embodiment, the elastic force of the support spring is much greater than the gravity of the support, so that the support can move freely in the accommodating box. Specifically, the support is arranged at the intersection of the axes (central axes) of the three sleeves 12. The support is connected with three indicating shafts 22. The three indicating shafts 22 are movably penetrated in the sleeve 12 in a one-to-one correspondence. The three indicating shafts include an X-axis, a Y-axis and a Z-axis. Among them, the through holes in the inner walls of the two adjacent side parts are respectively penetrated with an X-axis and a Y-axis. The Z-axis is penetrated in the through hole of the top side wall. The end of the three indicating shafts 22 away from the support is aligned with the center of the circle of the dial 13 (i.e., the center of a plurality of concentric circle scale lines). When the indicating shaft moves in the sleeve along the radial direction of the sleeve, the indicating shaft deviates from the center of the plurality of concentric circle scale lines, and then the radial displacement of the indicating shaft in the sleeve can be displayed by the dial.

[0047] The transmission rod 3 has a first end and a second end relative to each other. The second end of the transmission rod is used to fix the connection template 6. The first end of the transmission rod is inserted into the through hole of the inner wall of the other side of the accommodating square box, and the first end of the transmission rod is connected to the support by a ball joint. Specifically, the first end of the transmission rod forms a ball head, and the support is provided with a spherical groove, and the ball head of the transmission rod can be rotatably accommodated in the spherical groove. In this embodiment, the lifting thrust of the support spring allows the transmission rod to be arranged along the horizontal square box in the absence of external force. When the template is deformed, the transmission rod is driven to produce a corresponding displacement. Since the transmission rod is universally connected to the support by the ball joint, the support forms a corresponding displacement in the accommodating square box, and then the support drives the three indicating shafts to produce axial displacement and radial displacement in their respective sleeves. The radial displacement can be obtained through the dial.

[0048] In this embodiment, the three sleeves 12 are respectively provided with a measuring mechanism 4. The measuring mechanism 4 is used to collect the axial displacement of the indicating shaft 22 in the sleeve 12 in real time.

[0049] When the template is displaced, the template deformation monitoring device of the tall building structure of the present invention obtains the axial displacement and radial displacement in the X direction, Y direction and Z direction of the three indicating axes through the dial and the measuring mechanism, and then the vector synthesis of the three groups (in three directions) of displacement or deformation data can roughly determine the deformation direction and deformation size of the template. The template deformation monitoring device of the tall building structure of the present invention can eliminate the disadvantage of affecting observation when scaffolding is set up outside the template of the tall building structure, and the deformation of the template is respectively reflected on the three-way indicating axis through the transmission rod and the support, and then the deformation direction and deformation size of the template are obtained through vector synthesis.

[0050] As a preferred implementation, the measuring mechanism 4 includes: a plurality of adjustable resistors 41 , a slide bar 42 , a driving rod assembly 43 , a driven rod assembly 44 and a current monitor 45 .

[0051] Among them, the number of sliders is adapted to the number of adjustable resistors. Multiple adjustable resistors are arranged at intervals along the circumferential direction of the sleeve 12. Each adjustable resistor 41 is arranged along the axial direction of the sleeve 12. The adjustable resistor 41 is fixed to the inner wall of the sleeve 12. The adjustable resistor is connected to a power supply. The slider 42 is fixed to the inner wall of the sleeve 12 and the slider and the adjustable resistor 41 are arranged in the same direction. One end of the driving rod assembly 43 is connected to the indicating shaft 22, and the other end of the driving rod assembly 43 is formed with a first slide groove. The slider 42 is slidably arranged in the slide groove. The driven rod assembly 44 is fixedly connected to the driving rod assembly 43. The driven rod assembly 44 is equipped with an electric stylus 441. The electric stylus 441 is movably connected to the adjustable resistor 41. The current monitor 45 is connected to the adjustable resistor 41 and the electric stylus 441.

[0052] The electric stylus 441 is connected to a power source. The power source, the adjustable resistor, the electric stylus and the current monitor form an electrical circuit. When the indicating shaft generates an axial displacement in the sleeve, the driving rod assembly is driven to move along the axial direction of the sleeve, thereby causing the electric stylus to move along the length direction of the adjustable resistor to change the resistance value of the adjustable resistor, and the size of the adjustable resistor is reflected by the current monitor. The resistance value of the adjustable resistor is calculated by the current value obtained by the current monitor, and then the axial displacement of the indicating shaft in the sleeve is obtained.

[0053] In this embodiment, the current monitor is a current waveform simulator. Setting the peak value of the current signal waveform simulator can provide a timely warning of deformation and can also collect data on deformation 24 hours a day.

[0054] In this embodiment, the indicating shaft 22 is coaxially mounted with a connecting disk 221 . The driving rod assembly 43 is connected to the connecting disk 221 .

[0055] Specifically, the driving rod assembly 43 includes a fixed rod 431 and a hinged rod 432 with adjustable length.

[0056] A sliding groove is provided at one end of the fixed rod 431. The driven rod assembly 44 is connected to the fixed rod 431. One end of the hinged rod 432 is hingedly connected to the connecting plate 221 through a first hinge shaft. In some embodiments, one end of the hinged rod is hingedly connected to the connecting plate through a plane bearing. The other end of the hinged rod 432 is hingedly connected to the other end of the fixed rod 431 through a second hinge shaft. The first hinge shaft and the second hinge shaft are arranged along the axial direction of the sleeve 12.

[0057] The support interlock drives the movement of the three indicating shafts. The indicating shaft may not move in a standard straight line during movement, and there may be a certain angle of deviation. At this time, the connecting plate installed on the indicating shaft will interlock the driving rod assembly connected to it to change a certain angle in the cross section, thereby ensuring that the measuring mechanism does not move relative to each other in multiple dimensions. When ensuring that the measuring mechanism runs according to the predetermined trajectory (the axial direction of the sleeve), the data collected at this time is the pure deformation in the X\Y\Z direction.

[0058] In this embodiment, the hinge rod 432 includes: a core rod body and a sleeve. One end of the core rod body is hingedly connected to the fixed rod 431 through a second hinge shaft. The sleeve can be sleeved on the other end of the core rod body movably along the length direction of the core rod body. The end of the sleeve away from the core rod body is hingedly connected to the connecting plate 221 through a first hinge shaft.

[0059] In this embodiment, the number of the adjustable resistors 41 is four, and the four adjustable resistors 41 are arranged at equal intervals.

[0060] Continue reading Figure 4 and Figure 5 As shown, the wall of the sleeve is sunken toward the inside of the sleeve to form a groove, and the wall of the sleeve at the groove is provided with a strip hole arranged along the axial direction of the sleeve, and the driven rod assembly is respectively movably inserted into the strip hole of the wall of the sleeve at the groove. The sliding bar and the adjustable resistor are respectively arranged on opposite sides of the groove. A pointer is installed on the outside of the wall of the sleeve, and a ruler is installed in the middle of the driven rod assembly, and the ruler is arranged along the axial direction of the sleeve. The pointer points to the ruler. When the axial displacement of the indicating shaft cannot be obtained due to a fault of the current monitor or other reasons, the axial displacement of the indicating shaft can be obtained by observing the position of the pointer pointing to the ruler on the outside of the sleeve. In addition, the axial displacement of the indicating shaft indicated by the pointer can also be used to verify the current value calculated by the current monitor to obtain the axial displacement of the indicating shaft.

[0061] In this embodiment, see Figure 5 The hole walls on opposite sides of the strip hole of the tube wall of the sleeve form limiting grooves opposite to each other, and the driven rod assembly is coaxially and rotatably mounted with a roller, and the opposite sides of the roller are rotatably embedded in the limiting grooves in the hole walls on opposite sides of the strip hole.

[0062] The support platform is installed at the monitoring point through a support frame. The support frame includes: a platform plate 51, a base 52 and a column 53.

[0063] The platform plate 51 is arranged in the horizontal direction. The support is fixed on the upper part of the platform plate 51. The base 52 is fixed at the monitoring point (such as the outer side of the template, and the monitoring point can be set by avoiding the scaffolding erected outside the template). The base 52 is vertically provided with a height-adjustable column 53. The column 53 is supported on the platform plate 51.

[0064] In this embodiment, the column includes a plurality of sleeves connected by threads.

[0065] Preferably, the transmission rod 3 is equipped with a bubble level 32. When installing the template deformation monitoring device for tall building structures of the present invention, first ensure that the transmission rod is horizontally set, and the bubble level can be used to observe whether the transmission rod is horizontally set in the initial state.

[0066] The template deformation monitoring device of the tall building structure of the present invention can collect data in a safe area through electrical signal control; during use, mechanical data (pointer and scale) and electrical signal simulation data (current monitor) can be used for comparative analysis; under the condition of ensuring working electricity, the monitoring device can continuously collect and collect data for 24 hours. In addition, the measuring points can be arranged arbitrarily, and the measuring points can be arranged arbitrarily on the working surface without being affected by the visual conditions. On the other hand, the data collection is continuous and efficient without time gaps, and early warning can be given in time when an accident occurs.

Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
