Description

Technical Field

[0001] The utility model relates to the technical field of high pier bridge engineering construction, in particular to a temperature control device for hollow high pier concrete hydration heat construction. Background Art

[0002] After pouring large volumes of concrete, the hydration heat of cement will cause the temperature inside the concrete to rise significantly, with the highest temperature reaching 60-80°C, and sometimes even exceeding 90°C. The heat dissipated from the concrete surface is relatively fast, so the concrete forms a temperature difference between the inside and outside, causing compressive stress inside the concrete and tensile stress outside. The elastic modulus and tensile strength of concrete in the early stage are very low, so cracks are easily generated on the concrete surface, affecting the safety of the building. The commonly used concrete temperature control technology is the cooling water pipe method, which uses cold water to absorb the hydration heat of concrete and control the maximum temperature of concrete.

[0003] The above-mentioned and existing related technologies often have the following defects: the existing construction temperature control device usually adopts flange and bolt method to connect the water outlet main pipe, but due to the large number of bolts, the operation steps are cumbersome and time-consuming, which affects the efficiency of disassembly and installation of the water outlet main pipe. When the water outlet main pipe is damaged or under maintenance, the maintenance efficiency of the water outlet main pipe will be reduced.

[0004] Therefore, we propose a temperature control device for the hydration heat construction of hollow high pier concrete. Summary of the invention

[0033] The surface of the first flange 301 is fixedly connected with a plurality of positioning blocks 302, and the surface of the second flange 304 is provided with a plurality of positioning grooves.

When a temperature control device for the hydration heat construction of hollow high pier concrete needs to be installed with a water outlet main pipe 2, first a hole is drilled on the inner wall of the pier 1, and then the threaded sleeve 42 is fixed in the hole on the inner wall of the pier 1, and then the screw 43 connected with the first clamping ring 44 is screwed into the threaded sleeve 42, and the limiting ring 41 on the surface of the water outlet main pipe 2 is aligned with the groove of the first clamping ring 44, and then the water outlet main pipe 2 is placed in the first clamping ring 44, and then the second clamping ring 45 is rotated along the rotating shaft 48 so that the second clamping ring 45 wraps the water outlet main pipe 2, and then the screw 46 is passed through the first clamping ring 44 and the second clamping ring 45, and then the first clamping ring 44 and the second clamping ring 45 are fixed with the nut 47.

[0035] The inner walls of the first clamp ring 44 and the second clamp ring 45 are fixedly connected with anti-skid pads 49, and the surfaces of the anti-skid pads 49 are provided with anti-skid grooves. The surface of the water outlet main pipe 2 is fixedly connected with a limit ring 41, and the cross section of the limit ring 41 is circular.

[0036] Working principle:

[0037] When a temperature control device for the hydration heat construction of hollow high pier concrete is needed to be used, first install the outlet main pipe 2 and the water supply main pipe 5, then connect the outlet main pipe 2 and the water supply main pipe 5 to the branch pipe 8, the branch pipe 8 is buried inside the pier 1, and then connect the outlet main pipe 2 to the cooling pool 6, and connect the water supply main pipe 5 to the water pump 7 and the cooling pool 6, and then connect the first flange 301 on the outlet main pipe 2 with the second flange 304, so that the positioning block 302 on the first flange 301 is engaged with the positioning groove on the second flange 304, and then the first connecting seat 305 is pressed against the first flange 301, and then the second connecting seat 306 is pressed against the second flange 304, and then the worker manually pushes the fixing frame 311 to rotate along the place connected with the second connecting plate 308, and while the fixing frame 311 rotates, it drives the elliptical extrusion block 310 to apply pressure to the push plate 309 on the first connecting plate 307, so that the first connecting seat 305 The first flange 301 and the second connecting seat 306 drive the second flange 304 to approach each other, and then the limiting pin 312 is inserted to fix the fixing frame 311. The rubber sealing ring between the first flange 301 and the second flange 304 enhances the sealing performance of the connection between the two water outlet main pipes 2 and minimizes the possibility of cooling water leakage. The positioning block 302 on the first flange 301 cooperates with the positioning groove on the second flange 304 to improve the stability of the water outlet main pipe 2 during connection, and also improves the convenience during installation. The limiting pin 312 on the second connecting plate 308 improves the stability of the connecting device 3 during use, so that when the fixing frame 311 is shaken by external force, the extrusion block 310 will not fall off the pushing plate 309. By setting the connecting device 3, the problem of complicated steps when connecting the water outlet main pipe 2 is solved, the installation and disassembly of the water outlet main pipe 2 is facilitated, and the convenience of equipment use is further improved.

[0038] When a temperature control device for the hydration heat construction of hollow high pier concrete needs to be installed with a water outlet main pipe 2, first, a hole is drilled in the inner wall of the pier 1, and then the threaded sleeve 42 is fixed in the hole in the inner wall of the pier 1, and then the screw 43 connected with the first clamping ring 44 is screwed into the threaded sleeve 42, and the limiting ring 41 on the surface of the water outlet main pipe 2 is aligned with the groove of the first clamping ring 44, and then the water outlet main pipe 2 is placed in the first clamping ring 44, and then the second clamping ring 45 is rotated along the rotating shaft 48 so that the second clamping ring 45 wraps the water outlet main pipe 2, and then the screw 46 is passed through the first clamping ring 44 and the second clamping ring 45, and then the first clamping ring is fixed with a nut 47. The ring 44 is fixed with the second clamping ring 45, and the anti-slip pad 49 on the surface of the first clamping ring 44 and the second clamping ring 45 makes the first clamping ring 44 and the second clamping ring 45 more stable when clamping the water outlet main pipe 2, and also increases the friction between the first clamping ring 44 and the second clamping ring 45 and the surface of the water outlet main pipe 2. The surface limiting ring 41 of the water outlet main pipe 2 and the first clamping ring 44 and the second clamping ring 45 cooperate to limit the water outlet main pipe 2 so that it will not fall off accidentally. By setting the fixing device 4, the problem of installing the water outlet main pipe 2 on the pier 1 is solved, and the stability of the connection between the water outlet main pipe 2 and the pier 1 is improved.
