Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a large-volume concrete temperature measuring device using a skip-bin method. Background Art

[0002] The skipping method is a construction method in which the super-long concrete block is divided into several small blocks for interval construction in the construction of large-volume concrete projects. After a short period of stress release, the several small blocks are connected into a whole, and the tensile strength of concrete is relied on to resist the temperature shrinkage stress of the next section. The skipping method makes full use of the principle that the concrete releases the restraint stress caused by most of the temperature deformation and drying shrinkage deformation in the early stage during 5-10 days, and can resist the shrinkage deformation tensile stress after having a certain strength in the later stage. The foundation of the building or the large-area concrete plane structure is divided into several small areas, and the construction is carried out according to the principle of "block planning, block construction, layered pouring, and overall forming" to replace permanent expansion joints or post-casting strips, and solve the problem of crack control of super-long structures. Concrete temperature monitoring and control is particularly important for the skipping method construction. The deformation of the concrete can be understood through the temperature, and the skipping process can be adopted in time. Previously, temperature monitoring was carried out by PVC sleeve + inserting mercury thermometer or pre-buried temperature measuring line plugged in electronic thermometer for manual monitoring.

[0003] For example, a large-volume concrete temperature measuring device disclosed in China Publication No. CN217716713U can measure the temperature of large-volume concrete. However, when the temperature measuring device is extended into the interior of the concrete, there is no limiting and fixing device to limit and fix the temperature measuring device, so that the temperature measuring device will shake inside the concrete, making the temperature measuring component not stable enough during temperature measurement. Summary of the invention

DETAILED DESCRIPTION

[0024] The technical solution in the embodiment of the present application is to solve the problem that there is no limiting fixing device to limit and fix the temperature measuring device, so that the temperature measuring device will shake inside the concrete, making the temperature measuring component 5 not stable enough during temperature measurement. The overall idea is as follows:

[0025] Embodiment 1

[0026] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 A large volume concrete temperature measuring device using a skipping bin method comprises a first protective tube 1 and a limiting plate 3.

[0027] A temperature measuring component 5 is installed at the inner bottom of the first protective tube 1. Specifically, a wire 6 is electrically connected to the temperature measuring component 5, and the wire 6 is electrically connected to the wireless transmission device. The temperature measuring component 5 can be a temperature sensor or other temperature measuring modules that can measure temperature. The first protective tube 1 is detachably connected to the limit plate 3. Specifically, a threading hole is provided on the limit plate 3 to facilitate the wire 6 to pass through. An auxiliary fixing member 4 is screwed on the limit plate 3; the auxiliary fixing member 4 includes a hand wheel 41, and a threaded rod 42 is fixedly connected to the hand wheel 41. The threaded rod 42 is screwed through the limit plate 3 and is rotatably connected to a tight plate 43. Among them, when measuring temperature, the large-volume concrete steel bars are tied, the wire 6 of the temperature measuring component 5 is first passed through the limit plate 3, and then the first protective tube 1 is installed at the bottom of the limit plate 3, and then the first protective tube 1 is connected to the temperature measuring component 5 and reserved inside the large-volume concrete tied steel bars. At this time, the limit plate 3 is erected on the surface of the steel bars tied to the large-volume concrete, and the hand wheel 41 is turned to rotate the threaded rod 42. At this time, the abutment plate 43 contacts and abuts against the surface of the steel bars tied to the large-volume concrete, and the external wire 6 is electrically connected to the wireless transmission device, so that the signal is transmitted to the information platform for real-time detection and reading of data. Through the cooperation of the hand wheel 41, the threaded rod 42 and the abutment plate 43, the contact between the limit plate 3 and the surface of the steel bars tied to the large-volume concrete is more stable to prevent movement, thereby increasing the stability of the temperature measuring component 5 and improving the accuracy of the temperature measurement data. Through the detachable connection between the first protective tube 1 and the limit plate 3, the entire device is easy to carry.

[0028] An anti-skid pad 44 is provided at the bottom of the abutment plate 43. The anti-skid pad 44 increases the friction force on the surface of the steel bars tied with the mass concrete.

[0029] The bottom of the limiting plate 3 is fixedly connected with a connector 7, and specifically, the connector 7 is a cylindrical shape with two ends open. The first protection tube 1 is threadedly connected to the connector 7. The top outer side of the first protection tube 1 is provided with a first external thread 11, and the inside of the connector 7 is provided with a first internal thread that matches the first external thread 11. The first protection tube 1 is detachably connected to the limiting plate 3 through the cooperation of the first external thread 11 and the first internal thread.

[0030] The difference from the first embodiment is that:

[0031] Embodiment 2

[0032] See also Figure 1 , Figure 2 , Figure 3 Figure 4 and Figure 5 , and further includes a plurality of second protection tubes 2, one second protection tube 2 is detachably connected to the first protection tube 1, a top end of the second protection tube 2 is detachably connected to a limit plate 3, and each second protection tube 2 is detachably connected to each other. Among them, by setting a plurality of second protection tubes 2, it is possible to perform temperature measurement operations on large-volume concrete with different thicknesses, with strong applicability and convenient operation.

[0033] The two ends of the second protective tube 2 are respectively provided with a second external thread 21 and a second internal thread 22 that cooperate with each other. The second internal thread 22 cooperates with the first external thread 11. The second external thread 21 cooperates with the first internal thread. When it is necessary to measure the temperature of a large volume of concrete with a relatively high thickness, the wire 6 is passed through each second protective tube 2 in turn, and then each second protective tube 2 is connected by the second internal thread 22 and the second external thread 21 respectively, and the connection between the first protective tube 1 and the second protective tube 2 is realized by the first external thread 11 and the second internal thread 22, and then the wire 6 at the top is exposed through the limit plate 3, and then the second protective tube 2 is connected to the limit plate 3 by the second external thread 21 cooperating with the first internal thread.

[0034] When using this application:

[0035] When measuring temperature, tie the steel bars of the large-volume concrete, first pass the wire 6 of the temperature measuring component 5 through the limit plate 3, then install the first protective tube 1 at the bottom of the limit plate 3, and then connect the first protective tube 1 to the temperature measuring component 5 and reserve it inside the steel bars tied to the large-volume concrete. At this time, the limit plate 3 is set on the surface of the steel bars tied to the large-volume concrete. At this time, turn the hand wheel 41 to rotate the threaded rod 42. At this time, the abutment plate 43 contacts and abuts against the surface of the steel bars tied to the large-volume concrete. The external wire 6 is electrically connected to the wireless transmission device, so that the signal is transmitted to the information platform for real-time detection and reading of data. Through the cooperation of the hand wheel 41, the threaded rod 42 and the abutment plate 43, the contact between the limit plate 3 and the surface of the steel bars tied to the large-volume concrete is more stable to prevent movement, thereby increasing the stability of the temperature measuring component 5 and improving the accuracy of the temperature measurement data. The detachable connection between the first protective tube 1 and the limit plate 3 facilitates the carrying of the entire device.

[0036] It should be noted that the specific model specifications of the temperature measuring component 5 and the wire 6 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The power supply and principle of the temperature measuring component 5 and the wire 6 are clear to those skilled in the art and will not be described in detail here.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
