Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a large-volume concrete cooling system with a steel bar bracket serving as a condenser pipe. Background Art

[0002] Mass concrete refers to large volumes of concrete with a minimum geometric dimension of at least 1m, or concrete that is expected to develop harmful cracks due to temperature changes and shrinkage caused by the hydration of cementitious materials in the concrete. Mass concrete has a relatively small surface area, and the heat released from cement hydration is relatively concentrated, resulting in a relatively rapid internal temperature rise. Large temperature differences between the inside and outside of concrete can cause temperature cracks in the concrete, affecting structural safety and normal use. To prevent temperature cracks in large concrete due to large temperature differences between the inside and outside, cooling methods are necessary. A water pipe cooling arrangement, in which pre-buried condenser pipes are used to lower the internal temperature of the concrete, is commonly used on construction sites.

[0003] Large-volume concrete steel bar supports use supports or stirrups welded from steel bars or steel sections to support the weight of the upper steel bars, control the elevation of the steel bars and the entire construction load of the upper operating platform. However, general steel bar supports and stirrups are relatively long and slender and have poor stability.

[0004] Therefore, how to create a new large-volume concrete cooling system in which the steel support also serves as a condenser, integrate the steel support and the condenser, and play a supporting and cooling role at the same time, is one of the important research and development topics at present. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a large-volume concrete cooling system in which a steel support also serves as a condenser pipe, so that it can play a supporting and cooling role at the same time, effectively reduce the internal temperature of the concrete, avoid cracks caused by the temperature difference between the inside and the outside, ensure construction quality, and thus overcome the shortcomings of the existing technology.

[0006] In order to solve the above technical problems, the utility model provides a large-volume concrete cooling system in which a steel bar support also serves as a condenser pipe, comprising a cooling water tank, a steel bar support and a condenser pipe;

[0007] The steel bar support includes horizontal bars and vertical bars, the horizontal bars are arranged in a crisscross pattern in the horizontal direction and are provided with multiple layers, and the vertical bars are vertically arranged at the ends and intersections of the horizontal bars, and the horizontal bars and the vertical bars form a grid-like support structure;

[0008] Several vertical poles and horizontal poles between the corresponding vertical poles are selected at intervals along the edges of both sides of the steel support in the transverse direction as condensation water pipes, and the vertical poles and horizontal poles selected as condensation water pipes are internally connected;

[0009] The inlet and outlet of the cooling water tank are connected to the condensing water pipe to form a cooling water circulation loop.

[0010] As an improvement of the present invention, the vertical rods and the horizontal rods selected as condensate pipes in the steel bar support are connected by a tee piece, and the connected horizontal rods are connected by two-way pieces.

[0011] Furthermore, the horizontal bars and vertical bars in the steel bar support that are not selected as condensation water pipes are not connected to the condensation water pipes, and the horizontal bars and vertical bars that are not selected as condensation water pipes are connected by fasteners.

[0012] Furthermore, the condensate pipe is injected with high-strength grouting material after the concrete pouring is completed and the concrete cooling is completed.

[0013] Furthermore, a steel mesh is laid above each layer of cross bars of the steel support.

[0014] Furthermore, a plurality of temperature monitoring devices are evenly arranged on the vertical poles of the steel bar support along the height direction.

[0015] Furthermore, a base is provided below the cooling water tank, a water outlet is provided near the bottom, and a water return port is provided on the top. The water outlet and the water return port are respectively connected to the condensation water pipe through a hose.

[0016] Furthermore, multiple layers of steel plate mesh are installed inside the cooling water tank, multiple water holes are opened on each layer of steel plate mesh, and ice-dropping windows are opened on the side walls of the cooling water tank.

[0017] After adopting such a design, the utility model has at least the following advantages:

[0018] 1. The steel bar bracket can support the upper steel bars after the lower steel bars of the ultra-thick base plate are tied, and its stability is far greater than the stirrup form used in traditional technology. At the same time, the bracket is combined with the condensation system to avoid concrete cracking caused by high temperature generated by hydration heat inside the large volume of concrete. The structural layout is reasonable, the construction operation is simple, and it can be widely promoted and used.

[0019] 2. By connecting the temperature monitoring device to the vertical pole, the internal temperature of the large volume concrete can be monitored in real time, and linked with the cooling system for control. The cooling system circulation efficiency or the outlet water temperature in the cooling water tank can be reasonably adjusted according to the monitoring data, and the internal temperature of the large volume concrete can be adjusted in real time to prevent concrete cracks caused by temperature differences.

[0020] 3. The utility model adopts vertical poles and horizontal poles to cool the large volume of concrete through water circuits. Compared with the previous cooling methods, the water circulation circuit is simple and the cooling effect is better. Moreover, when high-strength grouting materials are used for sealing, the structural stability can be better guaranteed.

[0021] 4. The cooling water tank in this utility model adopts multi-layer steel plate mesh to increase the natural flow distance of water and improve the heat dissipation effect. Ice cubes can be added to assist in cooling, which plays a significant role in reducing the number of water circulations in the cooling system and quickly reducing the temperature of large-volume concrete to the design requirements.

[0022] 5. The two connecting pieces and the three connecting pieces in the present invention combine the vertical poles and the horizontal poles into a closed circulating water system, which can prevent water leakage from affecting the internal water content of large-volume concrete during construction. The system has a simple structure and reasonable layout. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] See also Figures 1 to 4 The utility model provides a large-volume concrete cooling system in which a steel bar support also serves as a condenser pipe, comprising a cooling water tank 8, a steel bar support and a condenser pipe 6.

[0030] The steel bar support includes horizontal bars 1 and vertical bars 2. The horizontal bars are arranged in a crisscross pattern in the horizontal direction and are provided with multiple layers. The vertical bars 2 are vertically arranged at the ends and intersections of the horizontal bars 1. The horizontal bars 1 and the vertical bars 2 form a grid-like support structure. A steel mesh 11 is laid above each layer of horizontal bars 1 of the steel bar support.

[0031] Several vertical poles 2 and cross bars 1 between the corresponding vertical poles 2 are selected along the transverse edges of the steel support as condensation water pipes 6. The vertical poles 2 and cross bars 1 selected as condensation water pipes 6 are connected by tees 10. It should be noted that in actual construction, multiple layers of cross bars 1 can be selected as condensation water pipes 6 according to the height of the concrete. Figure 3 The single-layer cross bar 1 shown in the figure is only a basic setting as the condensation water pipe 6. If the concrete to be poured is too large in the width direction and two cross bars 1 need to be connected end to end, the connected cross bars 1 are connected by two-way pieces 9.

[0032] The cross bars 1 and vertical bars 2 in the steel bar support that are not selected as the condensation water pipe 6 are not connected to the condensation water pipe 6, and the cross bars 1 and vertical bars 2 that are not selected as the condensation water pipe 6 are connected by fasteners.

[0033] Preferably, a plurality of temperature monitoring devices 4 are evenly arranged along the height direction on the vertical pole 2 of the steel bar support, which are used to monitor the internal temperature of the concrete in real time, and are connected to an external controller through a wire to achieve linkage control with the cold water system. The cooling system circulation efficiency or the outlet water temperature in the cooling water tank is reasonably adjusted according to the monitoring data, and the internal temperature of the large volume concrete is adjusted in real time.

[0034] Preferably, the height of the vertical pole 2 selected as the condensation water pipe 6 in the steel support is higher than the height of the remaining other vertical poles 2. After the concrete pouring is completed and the concrete cooling is completed, high-strength grouting material can be easily injected into the condensation water pipe 6, and the structure stability is stronger after filling.

[0035] A base 3 is provided below the cooling water tank 8, a water outlet is provided near the bottom, and a return water outlet is provided at the top. The water outlet is connected to the water inlet side of the condensation water pipe 6 through the water inlet hose 5, and the return water outlet is connected to the return water side of the condensation water pipe 6 through the return water hose 7, forming a closed cooling water circulation loop.

[0036] Preferably, a plurality of layers of expanded metal 12 are installed inside the cooling water tank 8, and a plurality of water holes are opened on each layer of expanded metal 12. The expanded metal 12 increases the flow distance of the cooling water and improves the heat dissipation effect.

[0037] Preferably, an ice-dropping window (not shown in the figure) is opened on the side wall of the cooling water tank 8, and ice cubes can be added into the cooling water tank 8 according to usage requirements to assist in cooling and improve cooling efficiency.

[0038] During use, the present invention circulates cooling water through the cooling water tank 8, the water inlet hose 5, the condensate pipe 6, the return hose 7, and the cooling water tank 8, thereby cooling the concrete interior. The cooling water flow and temperature are controlled in conjunction with the temperature monitoring device 4. After the concrete is poured and cooled, the water inlet hose 6 and return hose 7 are removed, and high-strength grouting material is injected into the condensate pipe 6 to enhance support strength.

[0039] The utility model has a reasonable structural layout and simple construction operation. The steel bar bracket is integrated with the condensation water pipe, which can simultaneously support the upper steel bars and cool the concrete interior, thereby ensuring construction quality and improving construction efficiency.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form.
