Description

Technical Field

[0001] This utility model relates to the field of concrete steam curing technology, and in particular to a loading rack for steam curing phosphogypsum concrete blocks. Background Technology

[0002] Steam-cured concrete is a civil engineering material whose performance is improved through steam curing. It utilizes temperature and humidity control to accelerate the hydration reaction and is mainly used in the production of precast components and the manufacture of ballastless track slabs for high-speed railways and bridge beams. Its process is divided into a pre-curing period, a heating period (with steam condensation as the primary heat transfer method, followed by convection), a constant temperature period, and a cooling period. The rate of temperature change at each stage must be strictly controlled to avoid structural damage.

[0003] However, for concrete blocks, concrete slabs, and some small precast concrete components, it is difficult to store them individually like large components such as bridge beams. They need to be stacked, and during the steam curing process, it is inevitable that components in the middle of the stack will not receive full steam curing, while components on the periphery will be fully steam cured. This easily leads to incomplete and uneven steam curing. In particular, existing steam curing racks cannot be layered, and can only be stacked layer by layer, making it difficult to control the uniformity and completeness of the steam curing process. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a loading rack for steam curing phosphogypsum concrete blocks. The rack enables layered storage of concrete components through partition units, avoiding uneven steam curing between the inside and outside in the traditional stacking storage. It increases the number of steam circulation paths, ensuring that all surfaces of the components can come into contact with steam more, further improving the uniformity and quality of steam curing. The overall structure has strong load-bearing capacity, is stable and flexible, can be freely stacked, is easy to operate, highly efficient, and highly practical.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a loading frame for steam curing phosphogypsum concrete blocks, including a base structure and multiple partition units that cooperate with it. The base structure includes a base, a hollow groove is provided inside the base, an upper limit platform is provided in the hollow groove, a support plate is provided on the upper limit platform and multiple sets of first ventilation holes are provided on the support plate, forklift slots penetrating the base are symmetrically provided on both sides of the base, and multiple sets of first assembly slots are provided on the top of the base. The partition unit includes a partition frame, which is provided with a support groove and multiple sets of second assembly grooves. The support groove is provided with multiple sets of second ventilation holes. The bottom of the partition frame is provided with multiple sets of support legs that correspond to and cooperate with the multiple sets of first and second assembly grooves.

[0006] In a preferred embodiment, a reinforcing frame is provided inside the hollow trough.

[0007] In a preferred embodiment, the base has multiple sets of ventilation grooves symmetrically arranged on both sides of its bottom.

Detailed Implementation

[0019] Example 1: like Figure 1-6 The loading rack for steam curing phosphogypsum concrete blocks includes a base structure 1 and multiple interlayer units 2 that cooperate with it. The base structure 1 serves as the load-bearing foundation for the entire loading rack, enabling stable placement of single-layer or multi-layer components. It includes a base 4 with a hollow groove 5 inside. The hollow groove 5 not only provides installation and positioning space for the support plate 3 but also serves as the core channel for steam circulation, helping steam to circulate at the bottom of the loading rack. A limiting platform 8 is provided on the hollow groove 5, which can precisely limit the position of the support plate 3, preventing the support plate 3 from shifting due to steam impact or slight vibration during steam curing. The support plate 3 is provided with multiple sets of first ventilation holes 11, which are evenly distributed on the surface of the support plate 3, allowing the steam in the hollow groove 5 to permeate upwards evenly and reach the concrete component above the support plate 3. The base 4 is provided with forklift slots 7 symmetrically on both sides, which are opened to facilitate the insertion of forklift forks, realize the overall handling of the loading frame and the components on the frame, and greatly improve the loading, unloading and transfer efficiency. The top of the base 4 is provided with multiple sets of first assembly slots 10, which are used to precisely cooperate with the support legs 16 of the partition unit 2, providing a positioning reference for the assembly of the partition unit 2. The aforementioned partition unit 2 is used to store concrete components in layers, avoiding stacking and squeezing of components. It includes a partition frame 12, which is equipped with a support groove 13 and multiple sets of second assembly grooves 15. The shape of the support groove 13 is adapted to the concrete component, which can limit the component and prevent it from shaking or slipping during steam curing. The support groove 13 is equipped with multiple sets of second vent holes 14, which correspond vertically to the first vent holes 11 of the support plate 3, forming a continuous steam flow path to ensure that steam can penetrate to each layer of components from top to bottom. The bottom of the partition frame 12 is equipped with multiple sets of support legs 16 that correspond to and cooperate with multiple sets of first assembly grooves 10 and second assembly grooves 15. The shape of the support legs 16 is adapted to the groove shape of the assembly groove, and they can fit tightly after assembly to prevent the partition unit 2 from loosening or shifting under load. Furthermore, by cooperating with different assembly grooves, the assembly height and number of layers of the partition unit 2 can be flexibly adjusted. like Figure 3 In the preferred embodiment, the hollow trough 5 is provided with a reinforcing frame 6, which is distributed in a mesh or frame manner. This can enhance the overall structural strength of the base 4 without obstructing the steam flow, prevent the base 4 from deforming due to bearing the weight of multiple components, and improve the base 4's resistance to deformation under high temperature and high humidity steam curing environment. like Figure 3In the preferred embodiment, multiple sets of venting grooves 9 are symmetrically arranged on both sides of the bottom of the base 4. The venting grooves 9 are connected to the hollow groove 5, which allows steam in the steam curing environment to enter the hollow groove 5 from the bottom of the base 4, forming a complete steam path of "bottom steam inlet - middle circulation - top permeation". At the same time, it can also discharge the condensed water in the hollow groove 5 in time, preventing the condensed water from accumulating in the base 4 and affecting the steam curing quality of the components. like Figure 5 and 6 In a preferred embodiment, the support leg 16 is provided with a reinforcing arm 17 connected to the partition frame 12. The reinforcing arm 17 has an inclined or triangular support structure, with one end connected to the middle of the support leg 16 and the other end connected to the bottom of the partition frame 12. This can enhance the connection strength between the support leg 16 and the partition frame 12, prevent the support leg 16 from bending or breaking when bearing the weight of the component, and further improve the load-bearing capacity and structural stability of the partition unit 2. like Figure 3 In the preferred embodiment, the multiple sets of first assembly slots 10 are evenly distributed on each corner of the base 4. The evenly distributed first assembly slots 10 can make the support legs 16 of the partition unit 2 bear force evenly, and distribute the weight of the partition unit and components to each corner of the base 4, so as to avoid excessive local stress on the base 4 and deformation, while ensuring the coaxiality of the multi-layer partition unit 2 after assembly, and ensuring the overall structure is regular. like Figure 5 and 6 In the preferred embodiment, the multiple sets of second assembly slots 15 are evenly distributed on each corner of the partition frame 12, and their distribution positions correspond one-to-one with the first assembly slots 10 of the base 4. This facilitates the precise insertion of the support legs 16 of the upper partition unit 2, enabling rapid alignment and assembly of multiple partitions. At the same time, the evenly distributed second assembly slots 15 can evenly transfer the weight of the upper components to the lower partition frame 12, avoiding local stress concentration in the partition frame 12. like Figure 1-6 In the preferred embodiment, the base structure 1, the partition unit 2, and the support plate 3 are made of materials with steam corrosion resistance, high temperature resistance, and high strength. They can adapt to long-term high temperature and high humidity conditions in a steam curing environment, avoid the structural strength from decreasing due to rust and aging, and ensure the long service life and safety of the loading frame.

[0020] Example 2: like Figure 1-6 The working principle of this utility model is as follows: Install the support plate 3 on the base 4, and then place the concrete blocks to be steam cured on the support plate 3, ensuring that the adjacent concrete blocks are not in close contact. Then, according to the number of concrete blocks to be processed, freely set up the partition unit 2, and place the concrete blocks that are not in close contact with each other on the support groove 13. After the placement is completed, use a forklift to transport the whole assembly to the steam curing device through the forklift groove 7. During the steam curing process, in addition to the direct steam curing effect from the exposed surface of the concrete block, the steam also contacts all surfaces of the concrete block through the hollow groove 5, the venting groove 9, the first venting hole 11 and the second venting hole 14, so as to achieve comprehensive steam curing.

[0021] The beneficial effects of this utility model are as follows: the layered storage of concrete components is achieved through the partition unit, avoiding the uneven steam curing between the inside and outside under the traditional stacking storage; more steam circulation paths are increased to ensure that all surfaces of the components can be in contact with steam more, further improving the uniformity and quality of steam curing; the overall structure has strong load-bearing capacity, is stable and flexible, can be freely stacked, is convenient to operate, highly efficient, and highly practical.
