Description

Technical Field

[0001] The invention relates to the field of concrete casting structures, in particular to a raft foundation large-volume concrete cooling structure. Background Art

[0002] During the construction of large-scale concrete raft foundations, a large amount of heat is generated by the internal reaction during the solidification process of the concrete. Therefore, after cooling, the solidified concrete structure is prone to cracks and other quality problems due to thermal expansion and contraction. During the construction process, the concrete needs to be heat-dissipated. The most common heat dissipation method is to pre-set cooling pipes before concrete pouring, and circulate cooling water through pre-buried pipes after concrete pouring to achieve the purpose of cooling and temperature control. This cooling measure requires water towers, circulating pumps and other equipment, and the cooling pipes inside the concrete cannot be removed after construction. The layout structure of the circulating cooling pipes will also make backfilling more difficult.

[0003] Patent application number CN202120763711.X discloses a large-volume concrete cooling structure for raft foundations. It discloses a cooling scheme of vertically inserting multiple steel pipes in the concrete, and utilizing the good thermal conductivity of the steel pipes to dissipate the heat inside the concrete from the top. The scheme of this patent changes the active heat dissipation of traditional water cooling to completely passive heat dissipation. After the concrete is poured, if the distribution density of the steel pipes is too small, it will be difficult to meet the heat dissipation requirements of the concrete. If the distribution density of the steel pipes is too large, it will cause waste of manpower and material resources. Therefore, for this patent, when conditions such as the environment and building form change, the fault tolerance rate of the scheme is low, and a large number of steel pipes used for heat dissipation cannot be removed later.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example, see Figures 1 to 9 This embodiment provides a large-volume concrete cooling structure for a raft foundation, which can achieve passive or active heat dissipation effects on the concrete raft foundation, such as Figure 1 As shown, it includes concrete 100 and temperature control components 200 vertically inserted into the concrete 100. The tops of the temperature control components 200 all penetrate the concrete 100, and the tops of multiple groups of temperature control components 200 are connected and reinforced by angle irons 102, as shown in FIG. Figure 3 As shown, the temperature control assembly 200 includes three arcuate heat pipes 201, as shown in FIG. Figure 7 As shown, a metal base plate 101 is provided at the bottom of the concrete 100, and a ring-shaped interface 101a is provided in an array on the top surface of the base plate 101. Three heat pipes 201 are matched and plugged into the interface 101a. The top of the interface 101a is expanded outward in a conical shape, and a sealing soft glue 103 is filled between the conical surface of the interface 101a and the outer wall of the heat pipe 201.

[0030] like Figure 4 and Figure 6As shown, the arc axes of the three heat conducting pipes 201 are coaxial, and adjacent heat conducting pipes 201 are clamped with auxiliary pipes 202 (the angle between the auxiliary pipe 202 and the two walls of the heat conducting pipe 201 is 60 degrees, and the sides of the two walls that are away from each other are bent inward and contact each other), and a connecting rod 203 is provided along the arc axis of the heat conducting pipe 201, and the connecting rod 203 and the auxiliary pipe 202 are hinged (a cushion block 208 is matched and sleeved in the auxiliary pipe 202, and the cushion block 208 is fixedly connected to a short arm 208a, and the short arm 208a passes through the auxiliary pipe 202, and the connecting rod 203 is rotatably connected to a collar 1 209, and the collar 1 209 and the short arm 208a are connected. A transfer block 210 is hinged between the three heat pipes 201, and the short arm 208a and the collar 1 209 are located on the upper part of the hinge axis and interfere with each other), a steel wire rope 204 is pulled between the straight wall of the heat pipe 201 and the connecting rod 203 (a hole is opened on the straight wall of the heat pipe 201, and an open metal buckle 212 is clamped on the heat pipe 201 at the opening, the connecting rod 203 is slidably sleeved with the collar 211 along its axial direction, and the two ends of the steel wire rope 204 are respectively hung with the metal buckle 212 and the collar 211), a round cover 1 205 is sleeved on the top end of the three heat pipes 201, and the connecting rod 203 vertically penetrates the round cover 1 205 and is threadedly connected with a nut 206.

[0031] like Figure 4 and Figure 5 As shown, the top surface of the round cover 205 is hollow, and its hollow shape includes circular holes 205a distributed in a ring array around the connecting rod 203, and the top of the round cover 205 is covered with a dustproof pad 207. The top thread of the connecting rod 203 is parallel to its axial direction with a sliding groove 203a, and the round cover 205 is slidably connected to the sliding groove 203a.

[0032] The present invention provides a raft foundation mass concrete cooling structure, in particular, provides a temperature control component 200 that has both passive heat dissipation (relative to traditional water circulation cooling) and active heat dissipation (relative to patent CN202120763711.X), wherein the passive heat dissipation is referred to as Figure 1 , refers to the heat transfer from the interior of the concrete 100 to the top of the concrete 100 through the metal heat pipe 201 and the auxiliary pipe 202 for heat dissipation. Figure 8 , is the unique active heat dissipation (air cooling) function expansion of the temperature control component 200; refer to Figure 1 and Figure 3The temperature control component 200 is composed of three heat-conducting pipes 201 and three auxiliary pipes 202. Obviously, the heat-conducting area is much larger than that of the steel pipes in the existing patent solution. Although the use of more special-shaped metal pipes in the temperature control component 200 increases the material consumption, the temperature control component 200 of the present invention can be recycled and reused, while the heat-conducting steel pipes in the existing patent solution cannot be recycled. Therefore, the passive heat dissipation performance of the present invention is significantly better than that of the existing patent technology, and the cost of use is much lower than that of the existing patent solution. In addition, the temperature control component 200 of the present invention can also perform active heat dissipation by forced air cooling, and the function deployment is quick and convenient.

[0033] To achieve the above functions, the present invention involves the following technical details: First, regarding the arrangement and disassembly and recycling of the temperature control component 200, first, the temperature control component 200 needs to be stable and not loose during pre-installation. Figure 6 The adapter block 210 and the pad 208 on the collar 209 support the auxiliary pipe 202 outward (refer to Figure 6 When the connecting rod 203 is pressed down to tighten the auxiliary pipe 202, the right-angled side of the short arm 208a located at the upper part of its hinge axis contacts the collar 1 209 to limit the position. The steel wire rope 204 between the collar 211 and the heat pipe 201 restrains the heat pipe 201 inward, which makes the heat pipe 201 and the auxiliary pipe 202 squeeze tightly together, maintaining the self-stability of the structure. The overall cylindrical shape is plugged into the interface 101a on the bottom plate 101. At a position higher than the pouring height of the concrete 100, angle irons 102 are installed between the temperature control components 200 for structural reinforcement. When the concrete 100 solidifies, there is adhesion between the outer wall of the heat pipe 201 and the concrete, so it is impossible to directly pull the temperature control component 200 out of the concrete 100. Figure 4 and Figure 6 The circular hole 205a on the round cover 205 is used to buckle the flywheel wrench, the purpose of which is to prevent the round cover 205 and the connecting rod 203 connected to the round cover 205 through the sliding groove 203a from rotating relative to the temperature control component 200, making it easier to exert force when rotating the nut 206 downward. Rotating the nut 206 downward will cause the connecting rod 203 to drive the collar 209 to move upward relative to the round cover 205, so that the hinge structure between the collar 209 and the pad 208 has a tendency to bend, so that the pad 208 no longer presses the auxiliary pipe 202 against the heat conducting pipe 201. As the connecting rod 203 continues to rise, under the action of gravity, the auxiliary pipe 202 and the pad 208 have a tendency to swing downward toward the connecting rod 203, thereby further increasing the width of the gap between the auxiliary pipe 202 and the heat conducting pipe 201; When the gap between the auxiliary pipe 202 and the heat conducting pipe 201 meets the requirements of the next operation, the flywheel wrench can be used to drive the circular cover 1 205 to rotate relative to the heat conducting pipe 201. The circular cover 105 drives the connecting rod 203 and the second ring 211 to rotate through the sliding groove 203a. The rotation of the second ring 211 will pull the wire rope 204 obliquely relative to the heat conducting pipe 201 instead of pulling it straight in the axial direction. This allows the heat conducting pipe 201 to be gradually opened from one side, which is more labor-saving during the peeling process from the concrete 100 and is less likely to cause permanent deformation of the heat conducting pipe 201. In addition, due to the elastic deformation of the connecting rod 203 during the twisting process, the part of the heat conducting pipe 201 near the circular cover 1 205 will be pulled first, and the heat conducting pipe 201 will gradually peel off from the concrete 100 from the top to the bottom, which also reduces the difficulty of peeling the heat conducting pipe 201 from the concrete 100.

[0034] Second, regarding active heat dissipation, such as Figure 2 and Figure 8 As shown, the temperature control assembly 200 further includes a second round cover 213, which replaces the first cover and is disposed between the heat pipe 201, the connecting rod 203 and the nut 206. Figure 9 As shown, the bottom surface of the second circular cover 213 is located between the heat conducting pipe 201 and the auxiliary pipe 202 and is provided with a special-shaped ring 214, and the outer wall of the special-shaped ring 214 is in contact with the heat conducting pipe 201 and the auxiliary pipe 202. The second circular cover 213 is provided with hollows inside and outside the special-shaped ring 214, and the top surface of the second circular cover 213 is provided with a second interface 215 around the hollow part, and the second interface 215 is sleeved with the fan 300; When active cooling is required, the air outlet of the fan 300 can be connected to a certain group of temperature control components 200 through the circular cover 213. Since the present invention is composed of multiple special-shaped tubes, it is only necessary to open a hole at the bottom of the heat-conducting tube 201 on the inner side of the device (without affecting the external sealing) to obtain a circulating air duct. Assuming that the fan 300 draws air outward, the air enters each heat-conducting tube 201 through the hollow on the circular cover 213, enters between the heat-conducting tube 201 and the auxiliary tube 202 through the hole at the bottom of the heat-conducting tube 201, and then flows upward through the hollow of the circular cover 213 to enter the fan 300 for discharge, thereby realizing forced air cooling and heat dissipation of the concrete 100 by the temperature control component 200.

[0035] In summary, the concrete raft foundation temperature control component 200 of the present invention is composed of multiple special-shaped tubes, connecting rods 203 and connectors between the special-shaped tubes and the connecting rods 203. It can realize passive heat dissipation of heat conducted by concrete 100, and active heat dissipation by forced air cooling. The heat dissipation function covers a wide range of scenarios and has high efficiency. The temperature control component 200 can be recycled and reused, which effectively solves the problem that when using steel pipes for heat conduction to cool the concrete 100 raft foundation in the prior art, the heat dissipation method is completely passive and the heat dissipation pipes cannot be recycled, resulting in a low fault tolerance and high construction material cost.

[0036] 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 the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
