Description

Technical Field

[0001] This invention relates to the field of concrete construction technology, and in particular to a concrete surface temperature monitoring device. Background Technology

[0002] To ensure effective control of construction quality and temperature cracks during the construction of concrete structures, improving the temperature monitoring facilities for concrete structures is an important measure.

[0003] High-strength concrete technology is widely used in modern engineering. Due to its high strength and cement content, the concrete undergoes a vigorous reaction, resulting in a concentrated release of heat from cement hydration and rapid internal heating, which can easily lead to a large temperature difference between the inside and outside of the concrete. When this temperature difference is significant, it can cause temperature cracks in the concrete, affecting structural safety and normal use. Despite various temperature control measures implemented during construction, temperature cracks still occur.

[0004] In concrete construction both domestically and internationally, comprehensive measures are typically taken to prevent concrete cracking, including structural design, raw material selection, mix design, construction planning, construction quality, concrete temperature control, curing, and surface insulation. Dynamic monitoring of the temperature during concrete construction and curing is particularly important. If real-time temperature changes inside and outside the concrete can be obtained through monitoring, and the concrete temperature can be dynamically adjusted according to appropriate temperature control methods to keep it within the allowable range, concrete quality can be effectively improved, and temperature cracks in concrete can be significantly reduced or eliminated.

[0005] Current concrete engineering projects generally employ conventional concrete surface monitoring methods such as attaching temperature sensors to the outer surface of the formwork and embedding thermometers at the contact surface between the formwork and the concrete. However, these methods have certain inconveniences: while attaching temperature sensors to the outer surface of the formwork is simple and convenient to install, the monitoring accuracy is low due to the obstruction of the formwork, and it is greatly affected by ambient temperature; embedding temperature sensors on the inner surface of the formwork improves monitoring accuracy by being close to the concrete, but because the sensors protrude inside the formwork, they will form grooves on the concrete surface after demolding, requiring later repair and affecting the appearance and quality of the concrete. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a concrete surface temperature monitoring device that solves the problems of low detection accuracy or impact on the shape of the concrete surface in existing technologies.

[0007] According to an embodiment of the present invention, a concrete surface temperature monitoring device is provided, which is used in conjunction with building formwork. It includes a flat sheet-shaped temperature sensor, a connecting rod and fasteners. The connecting rod is arranged perpendicular to the surface of the temperature sensor and is fixedly connected to the back of the detection surface of the temperature sensor. A wiring hole is provided in the middle of the connecting rod along the axial direction. A wire is provided in the wiring hole so that the wire passes through the wiring hole and connects to the inside of the temperature sensor.

[0008] The inner wall of the building template is provided with a groove that matches the shape and thickness of the temperature sensor. Inside the groove, corresponding to the position of the connecting rod, there is also a through-hole extending to the outside, so that when the temperature sensor is embedded in the groove, the detection surface of the temperature sensor is coplanar with the inner wall of the building template. The connecting rod extends through the mounting hole to the outside of the building template, so that the wire is connected to the outside of the building template. The fastener is set at the end of the connecting rod located outside the building template, thereby fixing the temperature sensor in the groove.

[0009] Furthermore, the connecting rod is a threaded rod, and the fastener is a nut.

[0010] Furthermore, it also includes a spacer that is set in conjunction with the detection surface of the temperature sensor. The spacer is made of thermally conductive plastic and is detachably connected to the detection surface of the temperature sensor, thereby covering the working surface of the temperature sensor.

[0011] Furthermore, several magnet blocks are embedded on the detection surface of the temperature sensor.

[0012] Furthermore, a number of iron plates are provided on one side of the partition corresponding to the magnet block, and the installation area of ​​the iron plates completely covers the location of the magnet block, so that the partition can be magnetically attracted to be tightly attached to the detection surface of the temperature sensor.

[0013] Furthermore, a sealing gasket is provided on the outer edge of the groove corresponding to the inner side of the building template. The sealing gasket contacts the edge of the detection surface of the temperature sensor, thereby filling and sealing the gap between the temperature sensor and the groove.

[0014] Furthermore, the sealing gasket is also disposed on the inner wall of the building template outside the groove, thereby surrounding the groove. The area of ​​the partition is larger than the area of ​​the temperature sensor detection surface and smaller than the maximum area occupied by the sealing gasket, so that when the temperature sensor is embedded inside the groove, the partition and the outer side of the sealing gasket are in close contact.

[0015] Furthermore, the sealing gasket is made of flexible silicone material.

[0016] Furthermore, the magnet block is an electromagnet, and the wire of the electromagnet is parallel to the wire of the temperature sensor, passing through the wiring hole and connecting to the outside of the building formwork.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention features a groove on the inner wall of a template, into which a temperature sensor is embedded. The sensor's detection surface is coplanar with the template's inner wall, forming a single unit. This allows the temperature sensor to directly contact the concrete surface without protruding from the template's exterior. This achieves a balance between high detection accuracy and maintaining the integrity of the concrete surface, enabling precise, real-time measurement of the concrete surface temperature with minimal impact from external ambient temperatures. Furthermore, the monitoring device is easy to assemble and disassemble from the template, facilitating large-scale industrial application. Attached Figure Description

[0023] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 As shown in the figure, this embodiment of the invention proposes a concrete surface temperature monitoring device, which is set in conjunction with a building formwork 1. In this embodiment, the building formwork 1 used for the conjunction can be of various shapes, as long as the building formwork 1 has an inner wall with a certain thickness, the thickness of which is greater than that of the temperature sensor 2 in this invention.

[0025] The temperature monitoring device of the present invention includes a flat, sheet-like temperature sensor 2, a connecting rod 3, and a fastener 4. The temperature sensor 2 is shaped to match the surface shape of the building template 1 and can be flat or curved. The connecting rod 3 is perpendicular to the surface of the temperature sensor 2 and is fixedly connected to the back of the detection surface of the temperature sensor 2. A wiring hole 31 is provided axially in the middle of the connecting rod 3, and a wire (not shown) is provided in the wiring hole 31 so that the wire passes through the wiring hole 31 and connects to the inside of the temperature sensor 2.

[0026] Correspondingly, the inner wall of the building template 1 is provided with a groove 11 that matches the shape and thickness of the temperature sensor 2. A through-hole extending to the outside is also provided inside the groove 11 corresponding to the position of the connecting rod 3, so that when the temperature sensor 2 is embedded in the groove 11, the detection surface of the temperature sensor 2 is coplanar with the inner wall of the building template 1. The connecting rod 3 extends through the mounting hole to the outside of the building template 1, allowing the wire to connect to the outside of the building template 1. The fastener 4 is positioned at the end of the connecting rod 3 located outside the building template 1, thereby fixing the temperature sensor 2 in the groove 11. The wire at the other end of the template can be connected to an electrical control or display device to power the temperature sensor 2, display the temperature of the temperature sensor 2, and control its working status. In this embodiment, preferably, the connecting rod 3 is a threaded rod, and the fastener 4 is a nut. After the connecting rod 3 passes through the mounting hole, the nut is screwed in from the outside end of the connecting rod 3, rotating inward until it is tightly against the outer wall of the template, thus completing the fixation. At this time, the detection surface of the temperature sensor 2 is exactly coplanar with the inner wall of the template, forming a unified plane.

[0027] like Figure 2 As shown, in a further embodiment of the present invention, a spacer 5 is also included, which is arranged in conjunction with the detection surface of the temperature sensor 2. The spacer 5 is made of thermally conductive plastic material, such as PP (polypropylene), PC (polycarbonate), or PPS (polyphenylene sulfide). In this embodiment, PP (polypropylene) is preferably used as the material of the spacer 5, as it has good thermal conductivity and its thickness is extremely small, negligible relative to the thickness of the temperature sensor 2, thus having almost no impact on the temperature measurement accuracy of the temperature sensor 2. The spacer 5 prevents the concrete from directly contacting the temperature sensor 2, avoiding the problem of the concrete being too tightly connected to the temperature sensor 2 during the solidification process, which could damage the temperature sensor 2 during demolding.

[0028] It should be noted that the partition 5 is detachably connected to the detection surface of the temperature sensor 2, thus covering the working surface of the temperature sensor 2. This allows the partition 5 and the concrete to separate as a whole from the temperature sensor 2 during demolding. The partition 5 can then be removed from the concrete. Considering that the partition 5 is made of extremely thin plastic, its removal will not affect the appearance or quality of the concrete. It also protects the integrity of the detection surface of the temperature sensor 2, eliminating the need for cleaning; a new partition 5 can be used for the next test. Preferably, several magnet blocks 21 are embedded in the detection surface of the temperature sensor 2. Several iron plates 51 are provided on one side of the partition 5 corresponding to the magnet blocks 21, with the installation area of ​​the iron plates 51 completely covering the location of the magnet blocks 21, allowing the partition 5 to be magnetically attracted and tightly attached to the detection surface of the temperature sensor 2. During installation, the spacer 5 is simply attached to the magnet 21 of the temperature sensor 2 via the iron sheet 51, forming an integrated structure between the spacer 5 and the temperature sensor 2. When the temperature sensor 2 is embedded in the groove 11, the spacer 5 seals the opening of the groove 11, thus enclosing the temperature sensor 2 internally and preventing concrete mortar from seeping into the groove 11 and contacting the temperature sensor 2, causing damage or solidifying it within the groove 11. When the concrete has hardened and demolding is required, the concrete is removed normally. When the applied force exceeds the magnetic attraction, the spacer 5 and the temperature sensor 2 will naturally separate without damaging the temperature sensor 2.

[0029] In the preferred embodiment, the magnet 21 is an electromagnet, and the wire of the electromagnet is parallel to the wire of the temperature sensor 2, passing through the wiring hole 31 and connecting to the outside of the building formwork 1. This allows the power to be turned on during installation, enabling the electromagnet to attract and fix the partition, completing the installation and sealing. When removing the formwork after the concrete has solidified, the power is turned off. At this point, the electromagnet no longer attracts the iron sheet 51 on the partition, and the partition and concrete can be separated from the building formwork 1 simultaneously, after which the partition can be removed.

[0030] In a further embodiment, a sealing gasket 6 is provided on the outer edge of the inner side of the groove 11 corresponding to the building formwork 1. The sealing gasket 6 contacts the edge of the detection surface of the temperature sensor 2, thereby filling and sealing the gap between the temperature sensor 2 and the groove 11. This further reduces the probability of concrete penetration. Additionally, the sealing gasket 6 is also provided on the inner wall of the building formwork 1 outside the groove 11, thus surrounding the groove 11. The area of ​​the partition 5 is larger than the area of ​​the detection surface of the temperature sensor 2, but smaller than the maximum area occupied by the sealing gasket 6, ensuring that when the temperature sensor 2 is embedded inside the groove 11, the partition 5 and the outer side of the sealing gasket 6 are in close contact. Thus, during installation, the partition presses the sealing gasket 6 towards the inner wall of the building formwork 1, ensuring close contact and achieving a better sealing effect.

[0031] In this embodiment, the sealing gasket 6 is made of flexible silicone material, which has a certain degree of flexibility, can deform inward and fit tightly against the partition, and is not easy to harden with the concrete, so that it can be used multiple times and maintain good sealing performance for a long time.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
