Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of concrete structures, and more specifically, to a novel porous structure of large-volume concrete capable of improving temperature control conditions. Background Art

[0002] With the continuous development of the construction industry, the use of mass concrete is becoming more and more widespread, such as high-rise building foundations, large equipment foundations, water conservancy dams, large ship locks, etc. However, due to the relatively small surface coefficient of mass concrete, the heat release of cement hydration is relatively concentrated, resulting in a relatively fast internal temperature rise. When the temperature difference between the inside and outside of the concrete is large, temperature cracks will occur in the concrete, affecting the structural safety and normal performance, which violates my country's current goal of creating "high-quality projects". Therefore, it is particularly important to take reasonable measures to control the internal temperature of mass concrete during construction.

[0003] The existing temperature control measures for large-volume concrete mainly include lowering the temperature of raw materials through air cooling, water cooling or liquid nitrogen cooling, laying cooling water pipes in concrete for cooling, etc., which have high costs such as electricity bills and equipment amortization fees. During the peak construction period, most projects have high concrete pouring intensity, which poses a huge challenge to the control of temperature control in all aspects. In addition, large-volume concrete materials are used in large quantities. For some gravity-type solid structures with good stress conditions, resource consumption is large and carbon emissions are high, which is not conducive to the green and low-carbon development of engineering construction.

[0004] Therefore, in order to prevent large-volume concrete from cracking, achieve less resource consumption, green construction, and lower temperature control costs, and thus create a "high-quality project", it is necessary to achieve innovative breakthroughs in structural design compared to traditional structures. Utility Model Content

[0005] The utility model aims to provide a novel porous structure of mass concrete which can improve temperature control conditions, so as to solve the technical problems of high temperature control cost and excessive resource consumption of mass concrete in the prior art.

[0006] In order to achieve these purposes and other advantages according to the utility model, a new type of porous structure of large-volume concrete is provided which can improve temperature control conditions, including a concrete cushion layer, a plurality of porous concrete layers, and a top concrete layer which are sequentially poured upward, a plurality of channels are evenly spaced on each porous concrete layer, each channel is arranged to vertically penetrate the corresponding porous concrete layer, and the channels on the upper and lower adjacent porous concrete layers are staggered on the horizontal plane and do not overlap at all.

[0007] Preferably, the channel is a cylindrical structure with a central axis arranged vertically.

[0008] Preferably, the channels of the same concrete porous layer are staggered and arranged at equal intervals in the width direction of the porous structure in two adjacent columns of the channels in the length direction, and between two adjacent columns of the channels, every three adjacent channels are arranged at the vertex positions of an equilateral triangle.

[0009] Preferably, a vertically penetrating heat conducting pipe is provided in each of the holes, the outer diameter of the heat conducting pipe is equal to the inner diameter of the hole, and the outer side of the heat conducting pipe is anchored and connected to the corresponding concrete porous layer.

[0010] Preferably, the top of the heat conducting pipe is covered and connected with a sealing cover, and the outer side of the top of the sealing cover is anchored and connected to the concrete porous layer above.

[0011] Preferably, the lower end of the sealing cover is matched with and sealed to the inner side of the heat-conducting pipe, and the upper end of the sealing cover is exposed outside the heat-conducting pipe and has an outer diameter not less than that of the heat-conducting pipe.

[0012] Preferably, the bottom edge of the heat-conducting pipe extends horizontally outward to form a heat-conducting ring, and the heat-conducting ring and the bottom of the heat-conducting pipe are jointly supported on the concrete cushion layer or the concrete porous layer of the lower layer, and are anchored to the concrete porous layer of the layer.

[0013] The utility model includes at least the following beneficial effects: the new porous structure of large-volume concrete that can improve temperature control conditions of the utility model includes a concrete cushion layer, multiple concrete porous layers, and a concrete top layer, wherein the concrete cushion layer and the concrete top layer are solid structures, and holes are arranged on the concrete porous layer, so that when the concrete porous layers are cast in layers, the holes can be used as heat dissipation channels connecting the air, and at the same time, the setting of the holes can significantly reduce the amount of concrete used, and the holes of each layer are evenly spaced, which is conducive to uniform heat dissipation, reduces the risk of concrete cracking, and ensures the quality of the project. It can replace the original cooling water pipe cooling solution, reduce temperature control costs, and reduce carbon emissions as a whole, which is more conducive to the green and low-carbon development of engineering construction. The holes on the upper and lower adjacent layers of concrete porous layers are staggered, which is conducive to ensuring uniform distribution of holes inside the large-volume concrete, ensuring structural strength, and ensuring structural stress safety.

[0014] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0019] In the description of the present invention, terms such as "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0020] like Figure 1 As shown, the utility model of the new porous structure of large-volume concrete that can improve temperature control conditions includes a concrete cushion layer 1, multiple concrete porous layers 2, and a concrete top layer 3 that are cast upward in sequence, and each concrete porous layer 2 is evenly spaced with multiple channels 4, each channel 4 is arranged to vertically penetrate the corresponding concrete porous layer 2, and the channels 4 on the upper and lower adjacent concrete porous layers 2 are staggered on the horizontal plane and do not overlap at all.

[0021] The concrete cushion layer 1 and the top concrete layer 3 are solid structures, and the channels 4 are arranged on the concrete porous layer 2, so that when the concrete porous layer 2 is cast in layers, the channels 4 can be used as heat dissipation channels connecting the air. At the same time, the setting of the channels 4 can significantly reduce the amount of concrete used. The channels 4 of each layer are evenly spaced, which is conducive to uniform heat dissipation, reduces the risk of concrete cracking, and ensures the quality of the project. It can replace the original cooling water pipe cooling solution, reduce temperature control costs, and reduce carbon emissions as a whole, which is more conducive to the green and low-carbon development of engineering construction. The channels 4 on the upper and lower adjacent layers of concrete porous layers 2 are staggered, which is conducive to ensuring that the channels 4 inside the large volume of concrete are evenly distributed, ensuring the structural strength and ensuring the safety of the structure.

[0022] In another technical solution, Figure 1 As shown, the channel 4 is a cylindrical structure with its central axis arranged vertically, so as to improve the heat dissipation efficiency of the concrete porous layer 2.

[0023] In another technical solution, Figure 1As shown, the channels 4 of the same concrete porous layer 2 are arranged in an evenly spaced and staggered manner in two adjacent rows in the length direction along the width direction of the porous structure, and between two adjacent rows of channels 4, every three adjacent channels 4 are arranged at the vertex positions of an equilateral triangle.

[0024] The equilateral triangle arrangement is conducive to ensuring structural stability, and the three channels 4 are distributed at the three vertices of the equilateral triangle with uniform spacing, which is conducive to ensuring uniform heat dissipation and structural strength of poured concrete.

[0025] In another technical solution, Figure 1 As shown, a vertically penetrating heat pipe 6 is arranged in each of the channels 4, the outer diameter of the heat pipe 6 is equal to the inner diameter of the channel 4, the outer side of the heat pipe 6 is anchored and connected to the corresponding concrete porous layer 2, and the heat pipe 6 is arranged. The heat pipe 6 can be made of waste plastics and the like, and mainly serves the function of guiding heat dissipation. When the hydration heat is released during the pouring of the current layer of concrete, the heat pipe 6 can be used to guide the heat into the air.

[0026] In another technical solution, Figure 1-2 As shown, the top of the heat pipe 6 is covered with a plugging cover 5, and the top outer side of the plugging cover 5 is anchored to the upper concrete porous layer 2. After the current concrete construction is completed, the plugging cover 5 is installed to facilitate the concrete pouring construction of the upper concrete porous layer 2 in the next stage, and at the same time, an isolation hole is formed inside the heat pipe 6 to reduce the concrete material.

[0027] In another technical solution, Figure 2 As shown, the lower end of the sealing cover 5 is matched with the inner side of the heat pipe 6 and sealed, and the upper end of the sealing cover 5 is exposed outside the heat pipe 6, and the outer diameter is not less than the outer diameter of the heat pipe 6, so as to improve the sealing performance and the vertical supporting capacity of the sealing cover 5.

[0028] In another technical solution, Figure 2 As shown, the bottom edge of the heat conducting pipe 6 extends outward horizontally to form a heat conducting ring 7, and the heat conducting ring 7 and the bottom of the heat conducting pipe 6 are jointly supported on the lower concrete cushion layer 1 or the concrete porous layer 2, and are anchored to the concrete porous layer 2. The heat conducting ring 7 is provided to improve the heat conduction and heat dissipation capacity on the one hand, and to stabilize the position of the heat conducting pipe 6 on the lower concrete cushion layer 1 or the concrete porous layer 2 on the other hand.

[0029] Of course, in order to improve the heat dissipation effect and the stability of the support connection of the internal structure of the concrete, the top of the heat pipe of each layer extends upward to the bottom of the concrete porous layer above, so as to introduce the heat in the heat pipe into the air faster and better to prevent it from accumulating on the top surface of the poured concrete, or the bottom of the heat pipe of each layer is embedded downward into the top of the concrete cushion layer below or the top of the concrete porous layer to facilitate the positioning and installation of the heat pipe. The top of the heat pipe can be higher than the top surface of the concrete porous layer by a certain height to improve the heat dissipation efficiency and prevent the concrete material from accidentally falling into or sticking to the heat pipe when pouring the concrete of the corresponding layer.

[0030] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the drawings shown and described herein.
