Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for concrete pouring, specifically, a temperature control system for large-volume concrete. Background Technology

[0002] Temperature control is a crucial aspect of mass concrete construction and a primary measure for ensuring its quality. During construction, appropriate control methods and techniques should be selected based on project requirements to ensure effective control and improve the overall quality of the mass concrete. These methods include choosing suitable pouring temperatures, employing pre-embedded water pipes and internal cooling systems, and strengthening temperature control measures.

[0003] During concrete construction, appropriate insulation measures should be taken to reduce temperature gradient changes on the surface of large-volume concrete. Generally, insulation measures should be implemented when the temperature change rate exceeds 15℃ / h. Furthermore, proper curing is essential to prevent excessive temperature stress. During curing, attention should be paid to maintaining heat and moisture, and the insulation effect should be checked regularly.

[0004] When using built-in pipes for temperature control of large concrete structures, the pipes, once installed, become embedded in the concrete matrix during the curing process. This embedding can cause the pipes to bend due to the shrinkage of the cured concrete. Furthermore, this bending can significantly impact the stress distribution within the cured concrete block. Utility Model Content

[0005] The purpose of this invention is to provide a temperature control system for large-volume concrete to solve the problem that the pipes of the embedded pipe type temperature control system for large-volume concrete are prone to deformation due to the curing of concrete.

[0006] To solve the above problems, the present invention adopts the following technical means:

[0007] A temperature control system for large-volume concrete includes a positioning grid frame, which is solidified within the concrete. A heat-conducting and temperature-controlling pipe is mounted on the positioning grid frame. The heat-conducting and temperature-controlling pipe is arranged in an S-shape along the laying surface of the positioning grid frame. Both ends of the heat-conducting and temperature-controlling pipe extend horizontally out of the projection range of the positioning grid frame and serve as the liquid inlet and liquid outlet, respectively. The heat-conducting and temperature-controlling pipe is detachably connected to the positioning grid frame via a flexible positioning mechanism.

[0008] Preferably, the positioning frame includes transverse reinforcing ribs and longitudinal reinforcing ribs. A plurality of transverse reinforcing ribs are arranged in the longitudinal direction, and a plurality of longitudinal reinforcing ribs are arranged in the transverse direction. Each transverse reinforcing rib passes through the upper and lower sides of different longitudinal reinforcing ribs in sequence, and each longitudinal reinforcing rib passes through the upper and lower sides of different transverse reinforcing ribs in sequence.

[0009] Furthermore, the heat-conducting and temperature-controlling pipe includes a transverse section parallel to the transverse reinforcing rib and a vertical section parallel to the longitudinal reinforcing rib. The transverse section is located above or below the longitudinal reinforcing rib, and the vertical section is attached to the outermost longitudinal reinforcing rib and passes through the upper or lower side of the transverse reinforcing rib in sequence.

[0010] Furthermore, the soft positioning mechanism detaches and connects the transverse segment and the transverse reinforcing rib.

[0011] Furthermore, the soft positioning mechanism includes a first winding strip wound on the transverse section and a second winding strip wound on the transverse reinforcing rib, the first winding strip and the second winding strip being detached and connected by a telescopic positioning mechanism.

[0012] Furthermore, the first winding tape wraps around the transverse segment, and the two ends of the first winding tape are clamped and positioned by the first clamp; the second winding tape wraps around the longitudinal segment, and the two ends of the second winding tape are clamped and positioned by the second clamp.

[0013] Furthermore, the telescopic positioning mechanism includes a first positioning part connected to the first winding tape and a second positioning part connected to the second winding tape. A threaded sleeve is installed at the end of the first positioning part away from the first winding tape, and an external threaded block is installed at the end of the second positioning part away from the second winding tape. The external threaded block is threadedly connected to the threaded sleeve, and the length of the external threaded block is less than the depth of the threaded sleeve.

[0014] This utility model has the following beneficial effects during use:

[0015] Before the large concrete blocks harden, heat-conducting and temperature-controlled pipes are arranged in an S-shape on a positioning mesh frame. The positioning mesh frame, containing the heat-conducting and temperature-controlled pipes, is then placed inside the large concrete block, with both the inlet and outlet ends of the pipes extending beyond the concrete block. During the hardening process, the required temperature liquid can be introduced into the heat-conducting and temperature-controlled pipes through the inlet end, thereby regulating the internal temperature of the large concrete block during hardening. The positioning mesh frame's rigidity effectively prevents the heat-conducting and temperature-controlled pipes from bending due to the concrete's shrinkage during hardening. Furthermore, the addition of the positioning mesh frame not only prevents uneven stress distribution within the hardened concrete block caused by bending of the heat-conducting and temperature-controlled pipes, but also reinforces the large concrete block.

[0025] Please refer to Figure 1 and Figure 2 As shown, a temperature control system for large-volume concrete includes a positioning grid 1, which is solidified within the concrete. A heat-conducting and temperature-controlling pipe 2 is mounted on the positioning grid 1. The heat-conducting and temperature-controlling pipe 2 is arranged in an S-shape along the laying surface of the positioning grid 1. Both ends of the heat-conducting and temperature-controlling pipe 2 extend horizontally out of the projection range of the positioning grid 1 and serve as an inlet end 3 and an outlet end 4, respectively. The heat-conducting and temperature-controlling pipe 2 is detachably connected to the positioning grid 1 via a soft positioning mechanism 9.

[0026] Before the large concrete blocks harden, the heat-conducting and temperature-controlled pipes 2 are arranged in an S-shape on the positioning frame 1. The positioning frame 1, with the heat-conducting and temperature-controlled pipes 2, is placed inside the large concrete block, with both the inlet end 3 and the outlet end 4 of the heat-conducting and temperature-controlled pipes 2 extending beyond the concrete block. During the hardening process, the liquid at the required temperature can be introduced into the heat-conducting and temperature-controlled pipes 2 through the inlet end 3, thereby regulating the internal temperature of the large concrete block during hardening. The positioning frame 1, with its rigidity, effectively prevents the heat-conducting and temperature-controlled pipes 2 from bending due to the shrinkage of the hardened concrete. Furthermore, the addition of the positioning frame 1 not only prevents the heat-conducting and temperature-controlled pipes 2 from bending, thus avoiding uneven stress distribution within the hardened concrete block, but also reinforces the large concrete block.

[0027] Furthermore, the positioning frame 1 includes transverse reinforcing ribs 5 and longitudinal reinforcing ribs 6. A plurality of transverse reinforcing ribs 5 are arranged in the longitudinal direction, and a plurality of longitudinal reinforcing ribs 6 are arranged in the transverse direction. Each transverse reinforcing rib 5 passes through the upper and lower sides of different longitudinal reinforcing ribs 6 in sequence, and each longitudinal reinforcing rib 6 passes through the upper and lower sides of different transverse reinforcing ribs 5 in sequence.

[0028] This not only improves the stability of the positioning grid 1 itself, but also ensures that the positioning grid 1 can maintain its original shape after the concrete substrate has hardened, thus avoiding deformation of the positioning grid 1 due to concrete hardening.

[0029] Furthermore, the heat-conducting and temperature-controlling pipe 2 includes a transverse section 7 parallel to the transverse reinforcing rib 5 and a vertical section 8 parallel to the longitudinal reinforcing rib 6. The transverse section 7 is located on the upper or lower side of the longitudinal reinforcing rib 6, and the vertical section 8 is attached to the outermost longitudinal reinforcing rib 6 and passes through the upper or lower side of the transverse reinforcing rib 5 in sequence.

[0030] In this way, by using the parallel arrangement of the horizontal section 7 and the interlacing arrangement of the vertical section 8, on the one hand, the heat conduction and temperature control pipe 2 can be positioned more stably with the positioning grid 1, and on the other hand, the number of bends of the heat conduction and temperature control pipe 2 can be reduced, so as to avoid the situation where the heat conduction and temperature control pipe 2 is affected by too many bends.

[0031] Furthermore, the soft positioning mechanism 9 disassembles and connects the transverse segment 7 and the transverse reinforcing rib 5.

[0032] Specifically, the soft positioning mechanism 9 includes a first winding strip 10 wrapped around the transverse section 7 and a second winding strip 11 wrapped around the transverse reinforcing rib 5. The first winding strip 10 and the second winding strip 11 are detached and connected by a telescopic positioning mechanism.

[0033] Furthermore, the first winding tape 10 surrounds the transverse segment 7, and both ends of the first winding tape 10 are clamped and positioned by the first clamp 12; the second winding tape 11 surrounds the longitudinal segment, and both ends of the second winding tape 11 are clamped and positioned by the second clamp 13.

[0034] Meanwhile, the telescopic positioning mechanism includes a first positioning part 14 connected to the first winding tape 10 and a second positioning part 15 connected to the second winding tape 11. A threaded sleeve 16 is installed at one end of the first positioning part 14 away from the first winding tape 10, and an external threaded block 17 is installed at one end of the second positioning part 15 away from the second winding tape 11. The external threaded block 17 is threadedly connected to the threaded sleeve 16, and the length of the external threaded block 17 is less than the depth of the threaded sleeve 16.

[0035] In this way, the distance between the transverse section 7 and the transverse reinforcing rib 5 can be adjusted by adjusting the depth of the external threaded block 17 inserted into the threaded sleeve 16.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
