Description

Technical Field

[0001] This invention relates to the field of engineering construction monitoring technology, and more specifically, to a temperature monitoring device for ultra-thick, large-volume concrete slabs and its usage method. Background Technology

[0002] Currently, according to the definition in GB50496-2009 "Code for Construction of Mass Concrete", mass concrete refers to large-volume concrete structures with a minimum geometric dimension of not less than 1m, or concrete that is expected to develop harmful cracks due to temperature changes and shrinkage caused by the hydration of cementitious materials. To address the issue that the large amount of heat of hydration generated during the pouring of the main building structure can cause temperature stress in the structure, leading to temperature stress cracks and affecting structural safety, engineers commonly use fans to cool the entire concrete pouring area, allowing the temperature in the concrete to dissipate quickly, thereby resolving temperature stress. However, in large-area concrete pouring, using a large number of fans to cover the area... Some areas are obviously impractical and costly in terms of manpower and resources. Moreover, during the process of pouring concrete onto the formwork, the temperature varies greatly across different locations in the entire pouring area due to factors such as external temperature, pouring rate, and vibration time of the vibrator. Within a certain time for air cooling, the high temperature in many pouring areas is not quickly dissipated, and internal temperature stress will still exist. Therefore, the inventor proposes a temperature monitoring device for ultra-thick, large-volume concrete base slabs and its usage method to quickly monitor the temperature at various locations during the pouring of large-area concrete. Engineers can then accurately locate the entire area of ​​the concrete and quickly cool it down by air cooling, ultimately ensuring construction quality. Summary of the Invention

[0003] The purpose of this invention is to provide a temperature monitoring device for ultra-thick, large-volume concrete slabs and its usage method, which can facilitate rapid monitoring of the temperature at various locations during the pouring of large-area concrete.

[0004] The embodiments of the present invention are achieved through the following technical solution: a temperature monitoring device for ultra-thick, large-volume concrete slabs, comprising a support frame, placement rods, temperature probes, a display device, and a support device. The placement rods are arranged on the top of the support frame and multiple rods are evenly arranged along the circumference of the support frame. Each placement rod has multiple notches along its length for engaging the temperature probes. The temperature probes are used to abut against the formwork at the bottom of the concrete and detect the temperature of the concrete at that location. The display device is used to receive the electrical signals transmitted by the temperature probes and display them on a screen. The support device is used to fix the support frame and support it to the ground.

[0005] Furthermore, the support frame includes a base rod and a sliding rod. The sliding rod is slidably inserted into the base rod and has scale lines along its length. A wing bolt is threaded through the base rod and abuts against the sliding rod. A sphere is fixedly mounted on the end of the sliding rod away from the base rod. A hinge ring is rotatably fitted on the sphere, and multiple ball-head protrusions are fixedly mounted on the circumferential wall of the sphere. A damping rubber ring is fixedly mounted on the surface of the hinge ring near the sphere. Multiple placement rods are hinged to the hinge ring, and the hinge axis of the multiple placement rods is on the same plane as the hinge ring. A first torsion member is provided on the hinge ring to drive the placement rods on the hinge ring to rotate and unfold to a plane along their hinge axis and maintain the unfolded state.

[0006] Furthermore, each of the placement rods is provided with an extension device at the end furthest from the sphere.

[0007] Furthermore, the display device includes a display, one end of the temperature probe is connected to a connector via a flexible wire, and the display is provided with multiple plug interfaces for inserting the connector.

[0008] Furthermore, the support device includes a support rod, an extension rod, a positioning rod, a positioning plate, and a locking assembly. Multiple hinge seats are uniformly fixed along the circumference of the base rod. The top wall and the side wall away from the base rod of each hinge seat have interconnected rotation openings. Each support rod corresponds to a hinge seat, and the support rod is rotatably connected within the rotation opening of the hinge seat. A second torque member is provided on the hinge seat to drive the support rod to rotate along its rotation axis and engage with the base rod. A brake caster is fixedly mounted on the support rod. The extension rod is slidably inserted into the end of the support rod away from the hinge seat. A fixing bolt is threaded through the support rod to abut and fix the extension rod. A rotation groove is provided at the end of the extension rod away from the support rod. The positioning rod is rotatably connected within the rotation groove of the extension rod. A threaded rod is fixedly mounted on the positioning plate and abuts against the ground. The threaded rod is threadedly connected to the positioning rod. The locking assembly drives the support rod to rotate along its rotation axis until it abuts against the bottom wall of the rotation opening fixed to the hinge seat.

[0009] Furthermore, the locking assembly includes a base and a rod fixedly connected to the base. The bottom wall of the base rod has a first groove for the rod to slide into. A limiting block is fixedly installed on the rod. The side wall of the first groove has a limiting groove for the limiting block to slide. The two ends of the limiting groove are closed. The length direction of the first groove is the same as the length direction of the limiting groove. An abutment block for abutting a support rod is slidably inserted on the side wall of the base rod. The abutment block corresponds to the support rod. A spring for driving the abutment block to retract into the base rod is sleeved on the abutment block. A receiving groove for accommodating the spring is opened on the base rod. One end of the spring is fixedly connected to the abutment block, and the other end is fixedly connected to the bottom wall of the receiving groove. The end of the rod away from the base is conical. The abutment block and the conical part of the rod abut against each other. The end of the abutment block abutting against the rod is inclined.

[0010] Furthermore, the placement rod includes a placement seat and a placement end rod. The placement seat is hinged to a hinge ring. A limiting rotating rod is fixedly provided at one end of the placement end rod near the placement seat. The limiting rotating rod, the placement seat, and the placement end rod are located on the same straight line. The limiting rotating rod is rotatably engaged with the placement seat, and a damping rubber ring is fixedly sleeved on the limiting rotating rod. The notch for engaging the temperature probe and the fixing seat are both located on the placement end rod.

[0011] Furthermore, the method of using the temperature monitoring device for ultra-thick, large-volume concrete slabs includes: S1: The worker first holds the base rod, presses the base against the ground, and makes the abutment block open all the support rods and locks the support rods in place. Then, the extension rod is pulled out from all the support rods and the fixing bolts are tightened to fix the position of the extension rod. S2: Then rotate the positioning rod to bring all the positioning plates against the ground. At this time, rotate the positioning plate to adjust the bottom rod so that it is vertical and supports the position of the bottom rod. S3: Unfold all the placement rods, and snap the temperature probes into the notches of the placement rods at appropriate intervals. At the same time, snap the hooks on the temperature probes into the slots to fix the temperature probes in place, and insert the connectors on each temperature probe into the display's interface. S4: Rotate the end rod around the limiting rod as the axis to align the temperature probe with the template at a suitable angle; S5: Rotate the hinge ring to bring all the placement rods and the template into the same plane; S6: Repeat steps S1-S5 multiple times to evenly place multiple ultra-thick, large-volume concrete base plate temperature monitoring devices on the ground, and then hook the hooks in the adjacent fixing seats of every two adjacent ultra-thick, large-volume concrete base plate temperature monitoring devices together; S7: Pass multiple temperature probes through the long groove of the extension strip pulled out by pulling the hook, and make the hooks of the temperature probes engage with the two sides of the extension strip. At the same time, evenly place the temperature probes on the extension strip, and insert the connector on each temperature probe into the corresponding display interface; S8: Finally, pull all the sliding rods upwards along the bottom rod so that all temperature probes are in contact with the template, and tighten the wing bolts to fix the position of the sliding rods; S9: Quickly determine the temperature of the corresponding area by observing the temperature displayed on the screen.

[0012] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects: 1. This invention involves evenly placing and fixing multiple ultra-thick, large-volume concrete base plate temperature monitoring devices on the ground, hooking the hooks in the adjacent fixing seats of every two adjacent ultra-thick, large-volume concrete base plate temperature monitoring devices together, fixing temperature probes on the placement end rods and extension coils, inserting the connectors on the corresponding temperature probes into the corresponding display interfaces, and finally moving and fixing them by sliding the sliding rods upwards, thereby abutting all the temperature probes against the template, thus completing the temperature monitoring network for concrete. During large-area concrete pouring, the temperature at various locations can be quickly monitored. Installation and disassembly are relatively simple, and the spacing between the temperature probes can be easily adjusted. The display screen shows the temperature readings for the corresponding areas. Since the extension coils are wound on the winding wheel, the extension length of the extension coils is adjustable, allowing workers to adjust the spacing between adjacent ultra-thick, large-volume concrete base plate temperature monitoring devices according to the appropriate monitoring distance, making concrete temperature monitoring simpler and more convenient.

[0013] 2. This invention, by setting up a sphere and a hinge ring, allows for easy adjustment of all placement rods to a plane parallel to the template when the hinge ring is rotated along the sphere. The damping rubber ring is engaged with the protrusion on the ball head of the sphere, which can easily fix the position of the hinge ring after rotation, and its fixing effect is also good. Rotating the placement end rod around the limiting rod as the axis allows the temperature probe to be aligned with the template at a suitable angle, thereby increasing the monitoring range. The damping rubber ring can effectively limit the position of the placement end rod after rotation. Attached Figure Description
