Description

Technical Field

[0001] This utility model belongs to the field of building components, specifically relating to a prefabricated concrete floor slab with a built-in phase change temperature regulation module. Background Technology

[0002] Driven by both industrialized construction and energy conservation and environmental protection, precast concrete slabs are widely used as efficient prefabricated horizontal components. However, traditional precast concrete slabs have limited heat capacity and insufficient buffering capacity against indoor temperature changes, resulting in poor indoor thermal comfort and increased energy consumption of air conditioning systems. Existing technologies include directly incorporating phase change microcapsules into concrete to enhance its heat storage capacity, but this method often adversely affects the workability and mechanical properties of the concrete, and the amount of phase change material added is limited, resulting in insignificant thermal regulation effects and complex construction processes. Therefore, there is an urgent need to design a precast concrete floor slab with a built-in phase change temperature regulation module. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model discloses a prefabricated concrete floor slab with a built-in phase change temperature regulation module, and specifically discloses the following technical solutions: A prefabricated concrete floor slab with a built-in phase change temperature regulation module includes a precast concrete base slab, a metal anchor frame installed at the upper end of the precast concrete base slab, a first concrete layer poured at the bottom of the metal anchor frame, a grid-like limiting structure installed at the top of the first concrete layer inside the metal anchor frame, a phase change temperature regulation module placed within the grid of the grid-like limiting structure, and a second concrete layer poured at the top of the metal anchor frame.

[0004] Furthermore, the phase change temperature control module includes a sealed outer shell and a phase change material filled inside the sealed outer shell, and the sealed outer shell is provided with a phase change material injection port.

[0005] Furthermore, the sealing shell is made of polypropylene, and the phase change material is either n-octadecane or n-hexadecane.

[0006] Furthermore, the metal anchor frame is composed of angle steel or channel steel welded together.

[0007] Furthermore, the grid-like limiting structure includes several longitudinal steel bars and several transverse steel bars distributed at equal intervals, with the longitudinal steel bars and transverse steel bars intersecting and being tied together for fixation.

[0008] Furthermore, a lifting ring is fixedly connected to the upper surface of the metal anchor frame.

[0009] Furthermore, a slot is provided on one side of the precast concrete base plate, and a locking block that mates with the slot is provided on the other side of the precast concrete base plate.

[0010] Furthermore, both the slot and the block are semi-cylindrical.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a built-in phase change temperature regulation module to separate the phase change material from the concrete material, thereby effectively avoiding the problem of deterioration in mechanical and construction performance caused by mixing the phase change material with building materials. It also increases the amount of phase change material used, thereby greatly improving the heat storage and temperature regulation capacity of the floor slab.

[0012] This invention utilizes a prefabricated metal anchor frame and a grid-like limiting structure to achieve rapid and precise positioning and installation of the phase change temperature control module, thereby improving construction efficiency and quality controllability.

[0013] The design of the clips and slots on both sides of the floor slab simplifies the on-site installation process and shortens the project cycle. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Reference Figures 1-8 A prefabricated concrete floor slab with a built-in phase change temperature regulation module includes a precast concrete base slab 1, a metal anchor frame 4 installed at the upper end of the precast concrete base slab 1, a first concrete layer 11 poured at the bottom inside the metal anchor frame 4, a grid-like limiting structure installed at the upper part of the first concrete layer 11 inside the metal anchor frame 4, a phase change temperature regulation module 8 placed in the grid of the grid-like limiting structure, and a second concrete layer 12 poured at the top inside the metal anchor frame 4.

[0026] In this embodiment, the size and quantity of the phase change temperature control module 8 can be determined according to actual conditions, and its total heat storage capacity can be calculated and matched according to the building's thermal requirements. The phase change temperature control module 8 is prefabricated in the factory, ensuring its reliability and consistency.

[0027] In this embodiment, the phase change temperature control module 8 includes a sealed outer shell and a phase change material filled in the sealed outer shell. The sealed outer shell is provided with a phase change material injection port 9. After the phase change material is injected into the sealed outer shell through the phase change material injection port 9, the phase change material injection port 9 is heat-sealed to prevent the phase change material from leaking.

[0028] In this embodiment, the sealing shell is made of polypropylene with a thickness of 0.5-3mm, which ensures the smooth heat absorption and release during the phase transition of the internal phase change material, resulting in low thermal resistance. The polypropylene sealing shell has a certain degree of toughness and sealing performance, ensuring that it will not break and leak the internal phase change material during concrete pouring and long-term use. Polypropylene has a low density and light weight, which has little impact on the self-weight of the precast component. The phase change material is one of n-octadecane or n-hexadecane, with a phase change temperature in the range of 20 to 35°C.

[0029] In this embodiment, the metal anchor frame 4 is composed of angle steel or channel steel welded together.

[0030] In this embodiment, the grid-like limiting structure includes several longitudinal steel bars 6 and several transverse steel bars 5 distributed at equal intervals. The longitudinal steel bars 6 and the transverse steel bars 5 intersect each other and are tied together for fixation.

[0031] In this embodiment, a lifting ring 7 is fixedly connected to the upper surface of the metal anchor frame 4, which facilitates hoisting.

[0032] In this embodiment, a slot 3 is provided on one side of the precast concrete base slab 1, and a locking block 2 that mates with the slot 3 is provided on the other side of the precast concrete base slab 1. Both the slot 3 and the locking block 2 are semi-cylindrical. Multiple floor slabs can be quickly positioned and connected by interlocking with each other.

[0033] Example 2

[0034] A method for manufacturing a prefabricated concrete floor slab with a built-in phase change temperature regulation module includes the following steps: Step 1: The phase change temperature control module 8 is filled and sealed with phase change material in the factory to ensure the packaging quality; the precast concrete base plate 1 is precast in the factory. Step 2: Concrete floor slabs are fabricated using a horizontal formwork. Templates are installed according to the component dimensions, typically using steel templates to improve the manufacturing precision of precast components.

[0035] Step 3: Install and fix the metal anchor frame 4 inside the template according to the design method, and tie the horizontal steel bars 5 and the longitudinal steel bars 6 to form a grid-like limiting structure that meets the design requirements.

[0036] Step 4: Pour the first concrete layer 11 to the corresponding height and wait for the concrete to initially harden.

[0037] Step 5: After the first concrete layer 11 has hardened, place the phase change temperature control module 8 within the grid of the grid-like limiting structure on the upper surface of the first concrete layer 11.

[0038] Step 6: Pour the second concrete layer 12 to completely cover the phase change temperature control module 8 and make it flush with the upper surface of the metal anchor frame 4. After pouring, carry out curing and demolding.

[0039] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
