Description

Technical Field

[0001] The invention relates to the technical field of deformation monitoring of construction engineering, in particular to a deformation monitoring device for a curved top formwork used for concrete pouring. Background Art

[0002] Concrete curved roof formwork casting is a commonly used construction technology in construction projects. It is mainly used to construct roofs with curved shapes or complex structures. This technology pre-designs and installs formwork with specific curved shapes, and then pours concrete inside the formwork. During the pouring process, concrete will gradually fill the internal space of the formwork and form the required curved roof structure under the constraint of the formwork. In order to ensure the smooth pouring of the concrete curved roof formwork and the quality of the structure, it is necessary to monitor the deformation of the curved roof formwork used for concrete pouring, so as to promptly discover and deal with the formwork deformation problem, thereby ensuring the safety and quality of the construction.

[0003] In current engineering practice, for the pouring of small and medium-sized curved top formwork, if professional tunnel curved top formwork deformation monitoring devices are used, there will be many shortcomings. From an economic point of view, professional devices are often expensive, which is undoubtedly a considerable expense for small and medium-sized engineering projects with limited budgets, increasing the economic burden of the project. Secondly, professional tunnel curved top formwork deformation monitoring devices are usually large in size and complex in structure, requiring professional technicians to operate and maintain. In the pouring of small and medium-sized curved top formwork, the use of such devices is not only cumbersome to operate, but may also fail to fully play its role due to site restrictions, resulting in a waste of resources. Since the deformation monitoring requirements of small and medium-sized curved top formworks are relatively simple, the high precision and versatility of professional devices cannot be fully utilized in many cases. To this end, we propose a curved top formwork deformation monitoring device for concrete pouring. Summary of the invention

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 17 A deformation monitoring device for a curved top formwork for concrete pouring comprises two walls 1, a pouring mold cavity 2 for concrete pouring is arranged at the upper part between the two walls 1, a plurality of fitting mechanisms 9 for monitoring the change of the pouring mold cavity 2 during concrete pouring are arranged below the pouring mold cavity 2, a deformation monitoring mechanism 8 for prompting mold cavity deformation is arranged at the lower end of the fitting mechanism 9, a horizontal reset mechanism 7 for accelerating the horizontal reset of the deformation monitoring mechanism 8 is arranged at the lower end of the deformation monitoring mechanism 8, a floating mechanism 6 is arranged at the lower end of the horizontal reset mechanism 7, an adjusting mechanism 5 for driving the floating mechanism 6, the horizontal reset mechanism 7, the deformation monitoring mechanism 8 and the fitting mechanism 9 to rise and fall is arranged at the lower end of the floating mechanism 6, a displacement mechanism 3 for driving the adjustment mechanism 5, the floating mechanism 6, the horizontal reset mechanism 7, the deformation monitoring mechanism 8 and the fitting mechanism 9 to move horizontally is arranged between the two walls 1, and a positioning guide mechanism 4 for assisting the floating mechanism 6 to rise and fall is arranged at the lower end of the displacement mechanism 3.

[0020] When in use, the displacement mechanism 3 must first be installed horizontally and firmly between the two walls 1, so as to serve as the horizontal movement basis of the entire monitoring device. Subsequently, multiple adjustment mechanisms 5, multiple floating mechanisms 6, multiple horizontal reset mechanisms 7, multiple deformation monitoring mechanisms 8 and multiple bonding mechanisms 9 are installed in sequence according to a predetermined order. During this process, the multiple bonding mechanisms 9 must be manually and accurately assembled into the required shape to ensure that they can adapt to casting cavities 2 of different shapes and sizes. After the assembly work is completed, the displacement mechanism 3 drives the multiple adjustment mechanisms 5, multiple floating mechanisms 6, multiple horizontal reset mechanisms 7, multiple deformation monitoring mechanisms 8 and bonding mechanisms 9 to reciprocate under the casting cavity 2. The dynamic movement method enables the monitoring device to monitor the deformation of the casting cavity 2 in real time and comprehensively. During the monitoring process, the floating mechanism 6 and its bonding mechanisms are adjusted by the adjustment mechanism 5 according to actual needs. The specified heights of the upper mechanisms are to ensure that the fitting mechanism 9 can fit tightly and evenly on the lower surface of the casting mold cavity 2. When the concrete is poured, the fitting mechanism 9 can capture the deformation of the mold cavity in real time and pass it to the deformation monitoring mechanism 8. As the concrete is gradually filled, the casting mold cavity 2 may undergo slight deformations, which will be captured in real time by the fitting mechanism 9 and accurately measured by the deformation monitoring mechanism 8. When the casting mold cavity 2 is deformed, the deformation monitoring mechanism 8 will tilt and deflect with the assistance of the horizontal reset mechanism 7, thereby accurately measuring the deformation, improving the accuracy of the measurement, and ensuring the stability of the monitoring device during the measurement process. When the deformation monitoring mechanism 8 detects that the deformation exceeds the preset threshold, it immediately sends a prompt signal to remind the operator to pay attention to the deformation of the mold cavity. The operator can take corresponding measures to adjust or correct in time to ensure the quality of concrete pouring; See also Figure 4 and Figure 5 The displacement mechanism 3 includes two support plates 301, which are fixedly connected to the opposite sides of the two walls 1, and the two ends of the support plates 301 are fixedly connected with connecting strips 302. A screw rod 303 is rotatably sleeved between the two connecting strips 302 on the same side through a bearing. Two optical axes 304 located above and below the screw rod 303 are also fixedly connected between the two connecting strips 302 on the same side. A sliding sleeve 305 is threadedly sleeved on the screw rod 303, and each optical axis 304 is provided with two guide sleeves. A main docking plate 307 is fixedly connected to the guide block 306, the sliding sleeve 305 and the four guide blocks 306 on the same side, a secondary docking plate 308 is fixedly connected to one side of the main docking plate 307, a top plate 309 is fixedly connected between the two secondary docking plates 308, a plurality of upper sleeve holes 3010 are arranged at equal intervals on the top plate 309, a bottom plate 3011 is fixedly connected between the two secondary docking plates 308 and below the top plate 309, a plurality of lower sleeve holes 3012 are arranged at equal intervals on the bottom plate 3011.

[0021] The displacement mechanism 3 is fixed to the wall 1 by two support plates 301 as a moving basis. The support plate 301 is rotated to sleeve the screw rod 303 through the connecting strip 302 to form a driving core. When the screw rod 303 is rotated by an external force, the sleeve 305 moves axially. To ensure smooth movement, the optical axis 304 and the guide block 306 cooperate to provide sliding guidance for the sleeve 305. The sleeve 305 and the guide block 306 are connected through the main docking plate 307 to form a stable moving frame. The auxiliary docking plate 308 connects the top plate 309 and the bottom plate 3011. The upper sleeve hole 3010 and the lower sleeve hole 3012 on the top plate 309 and the bottom plate 3011 provide convenience for the subsequent mechanism installation. The screw rod 303 rotates to drive the sleeve 305 to move, and the guide block 306 slides and guides on the optical axis 304 to achieve horizontal movement of the entire displacement mechanism 3 between the two walls 1, providing a stable moving platform for other mechanisms.

[0022] See also Figure 5 The positioning and guiding mechanism 4 includes four guide rods 401, which are arranged in a sliding manner and fixedly connected to the lower end of the bottom plate 3011 near the edge of the corresponding lower sleeve hole 3012. The lower end of the guide rod 401 is fixedly connected to a limiting buckle 402, and a sliding tube 403 is slidingly sleeved on the outer wall of the guide rod 401. The outer walls of the four sliding tubes 403 are fixedly sleeved on the positioning plate 404.

[0023] The positioning and guiding mechanism 4 realizes its guiding function through four guiding rods 401. The four guiding rods 401 are fixedly connected to the lower end of the base plate 3011 to provide a stable guiding path for the vertical movement of the relevant components of the floating mechanism 6. The lower end of the guide rod 401 is fixedly connected to a limiting buckle 402 to ensure that the guide rod 401 and the components thereon will not fall off or exceed the predetermined moving range during the movement. A sliding tube 403 is slidably sleeved on the guide rod 401. The sliding tube 403 slides along the guide rod 401 to provide the necessary degree of freedom for the lifting and lowering of the relevant components. At the same time, a positioning plate 404 is fixedly sleeved on the sliding tube 403. The positioning plate 404 not only provides additional support for the sliding tube 403, but also ensures the stability and accuracy of the entire positioning and guiding mechanism 4 in the vertical direction. When the floating mechanism 6 moves in the vertical direction, the floating mechanism 6 drives the sliding tube 403 to slide along the guide rod 401, and the limiting buckle 402 is used to prevent the sliding tube 403 from falling off or moving beyond the range during the movement, thereby improving the reliability of the entire monitoring device.

[0025] The adjusting mechanism 5 uses a worm wheel 505 and a worm 506 to achieve height adjustment. The lower plate 501 serves as a supporting base and is connected to the upper plate 503 through an internal threaded sleeve 504. The internal threaded sleeve 504 and the worm wheel 505 are fixedly connected to form a transmission core. The worm 506 is meshed with the worm wheel 505. The worm 506 drives the worm wheel 505 and the internal threaded sleeve 504 to rotate. The rotation of the internal threaded sleeve 504 drives the floating mechanism 6, the horizontal reset mechanism 7, the deformation monitoring mechanism 8 and the fitting mechanism 9 to rise and fall. The spline hole 507 inside the worm 506 is slidably sleeved with the spline shaft 508. The hand wheel 509 is rotated to drive the worm 506 to rotate, and then the worm wheel 505 and the internal threaded sleeve 504 are driven to rotate, thereby achieving precise adjustment of the height of the floating mechanism 6, the horizontal reset mechanism 7, the deformation monitoring mechanism 8 and the fitting mechanism 9.

[0028] See also Fig.11The horizontal reset mechanism 7 includes a docking bolt 701, which is threadedly sleeved on the upper end of the top rod 605.

The inner sides of both ends of the U-shaped bracket 703 are rotatably sleeved with a first rotating shaft 704 through a bearing, and an O-shaped frame 705 is fixedly connected between the two first rotating shafts 704. The end of the first rotating shaft 704 away from the O-shaped frame 705 is fixedly connected to a first rotating bar 706 located at the outer end of the U-shaped bracket 703. The two ends of the first rotating bar 706 are respectively fixedly connected to first upper hooks 707.

[0029] The docking bolt 701 connects the horizontal reset mechanism 7 and the top rod 605 to each other to ensure the synchronization of the two during the lifting process. The stabilizing plate 702 abuts against the upper end of the top rod 605 through the docking bolt 701 to provide stable support for the U-shaped bracket 703. The U-shaped bracket 703 is internally connected with the O-shaped frame 705 and the support sleeve 7011 through a bearing to form a rotatable structure. When the O-shaped frame 705 or the support sleeve 7011 is tilted or offset by an external force, the first rotating bar 706 and the second rotating bar 7012 will rotate accordingly. At this time, the first traction spring 708 and the second traction spring 7014 are respectively connected by the first traction spring 708 and the second traction spring 7014. Traction force is generated through the connection between the first upper hanging buckle 707 and the first lower hanging buckle 709, and the second upper hanging buckle 7013 and the second lower hanging buckle 7015. The elasticity and traction force of the first traction spring 708 and the second traction spring 7014 enable the O-shaped frame 705 and the support sleeve 7011 to quickly reset and maintain a horizontal state after being acted upon by an external force; when the floating mechanism 6 drives the horizontal reset mechanism 7 to rise and fall, the O-shaped frame 705 and the support sleeve 7011 maintain a horizontal state when acted upon by an external force, or quickly reset to a horizontal state after the external force disappears, thereby ensuring the accuracy and stability of the deformation monitoring mechanism 8 and the bonding mechanism 9.

A bubble level 804 is embedded inside the top cover 802 at the upper end of the positioning tube 801 to preliminarily determine whether the mechanism is in a horizontal state, which helps to calibrate and monitor the accuracy of deformation. When the monitored object is deformed, it will cause a slight tilt or displacement of the deformation monitoring mechanism 8 as a whole or in part, causing the position of the mercury 8010 inside the sealed glass tube 807 to change, which will cause the circuit between the first positive wire 808 and the second positive wire 809 to be connected.
