Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an auxiliary device for installing cooling pipes in large-volume concrete raft foundations. Background Technology

[0002] High-rise building foundation raft slabs are generally thick, with a large volume of concrete poured in a single operation, resulting in mass concrete. Mass concrete generates significant heat of hydration, and the internal and external heat dissipation properties differ, making it prone to temperature cracks. Controlling the temperature difference between the inside and outside of mass concrete through layered pouring and vibration, and controlling the concrete's initial temperature, can effectively control the generation and development of temperature cracks caused by temperature stress, ensuring the construction quality of mass concrete. Embedding cooling pipes inside the concrete is a common measure to control the temperature difference between the inner and outer surfaces and ensure construction quality. In common practical engineering projects, cooling pipes need to be tied and fixed to the vertical reinforcement within the raft slab. However, the number of vertical reinforcement bars in the raft slab is relatively small, and the placement of the cooling pipes is constrained by the measurement and location of the vertical reinforcement bars. Therefore, it is necessary to research an auxiliary device for installing cooling pipes in mass concrete raft slabs, which can more conveniently lay out cooling pipes inside the raft slab concrete. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing an auxiliary device for installing cooling pipes in large-volume concrete raft foundations.

[0005] A raft foundation large-volume concrete structure, including a concrete body and a top reinforcement assembly and a bottom reinforcement assembly respectively set at the top and bottom of the concrete body;

[0006] The cooling pipe installation auxiliary rod assembly includes a rod top bracing assembly, a rod, a rod bottom pipe bracing assembly, and a cooling pipe. The rod top bracing assembly and the rod bottom pipe bracing assembly are connected by the rod. Several rod top bracing assemblies are installed on the steel reinforcement assembly at the top of the raft slab, and the cooling pipe is hoisted and fixed by several rod bottom pipe bracing assemblies.

The longitudinal reinforcement at the bottom of the raft foundation is located above the transverse reinforcement and is arranged at equal intervals.

The bottom pipe-bracing assembly of the boom includes an upper arc plate, a lower arc plate, and a fixing bolt. The upper and lower arc plates are connected and fixed by the fixing bolt. The top of the boom is fixed to the bottom of the lower arc plate, and the bottom of the boom is fixed to the top of the upper arc plate.

[0010] Specifically, the upper and lower arc plates of the reinforcing bars are sleeved on the outer wall of the longitudinal reinforcing bars at the top of the raft slab and are fixed by the reinforcing bar fixing bolts. The upper and lower arc plates of the tube are sleeved on the outer wall of the cooling pipe and are fixed by the tube fixing bolts.

[0011] Specifically, the boom is a length-adjustable boom, including an upper boom, a lower boom, and a plug ring.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] like Figures 1-5 As shown, an auxiliary device for installing cooling pipes in large-volume concrete raft foundations includes:

[0026] The raft foundation large-volume concrete structure 1 includes a concrete body 11 and raft foundation top reinforcement assemblies 12 and bottom reinforcement assemblies 13 respectively disposed at the top and bottom of the concrete body 11. Specifically, the raft foundation top reinforcement assembly 12 includes top transverse reinforcement 121 and top longitudinal reinforcement 122, with the top longitudinal reinforcement 122 located below the top transverse reinforcement 121 and arranged at equal intervals. The raft foundation bottom reinforcement assembly 13 includes bottom transverse reinforcement 131 and bottom longitudinal reinforcement 132, with the bottom longitudinal reinforcement 132 located above the bottom transverse reinforcement 131 and arranged at equal intervals. The concrete body 11, the raft foundation top reinforcement assembly 12, and the raft foundation bottom reinforcement assembly 13 together constitute the raft foundation large-volume concrete structure 1.

[0027] The cooling pipe installation auxiliary rod assembly 2 includes a rod top bracing assembly 21, a rod 22, a rod bottom pipe bracing assembly 23, and a cooling pipe 24. The rod top bracing assembly 21 and the rod bottom pipe bracing assembly 23 are connected by the rod 22. Several rod top bracing assemblies 21 are installed on the raft top steel reinforcement assembly 12, and the cooling pipe 24 is hoisted and fixed by several rod bottom pipe bracing assemblies 23. Specifically, the top bracing assembly 21 of the boom includes an upper arc plate 211, a lower arc plate 212, and a bracing fixing bolt 213. The upper arc plate 211 and the lower arc plate 212 are connected and fixed by the bracing fixing bolt 213. The bottom tube-bracing assembly 23 of the boom includes an upper arc plate 231, a lower arc plate 232, and a tube-bracing fixing bolt 233. The upper arc plate 231 and the lower arc plate 232 are connected and fixed by the tube-bracing fixing bolt 233. The top of the boom 22 is fixed to the bottom of the lower arc plate 212, and the bottom of the boom is fixed to the top of the upper arc plate 231. The upper arc plate 211 and the lower arc plate 212 are sleeved on the outer wall of the longitudinal reinforcement 122 at the top of the raft slab and are connected and fixed by the bracing fixing bolt 213. The upper arc plate 231 and the lower arc plate 232 are sleeved on the outer wall of the cooling pipe 24 and are connected and fixed by the tube-bracing fixing bolt 233.

[0028] Furthermore, such as Figure 6 , Figure 7 As shown, the boom 22 is a length-adjustable boom, including an upper boom 221, a lower boom 222, and a ring 223. The top of the upper boom 221 is fixed to the top bracing assembly 21 of the boom, the bottom of the lower boom 222 is fixed to the bottom bracing assembly 23 of the boom, and the ring 223 is fixed to the top of the lower boom 222. The upper boom 221 is inserted through the ring 223 and welded to be fixed.

[0029] In operation, the upper arc plate 211 of the reinforcing bar is placed on top of the longitudinal reinforcing bar 122 at the top of the raft slab, and the lower arc plate 212 of the reinforcing bar is placed at the bottom of the longitudinal reinforcing bar 122 at the top of the raft slab. They are then connected and fixed using reinforcing bar fixing bolts 213. The upper arc plate 231 of the cooling pipe is placed on top of the cooling pipe 24, and the lower arc plate 232 of the cooling pipe is placed at the bottom of the cooling pipe 24.

If an adjustable hanger 22 is used, the position of the long rod 221 passing through the insert ring 223 is adjusted as needed, and then welded. This invention allows for flexible changes in the number and position of the auxiliary hanger assembly 2 for cooling pipe installation according to actual engineering needs, thereby ensuring that the number and position of the cooling pipes 24 meet the requirements, guaranteeing the construction quality of large-volume concrete, and offering high flexibility and convenience in practical use.
