Description

Technical Field

[0001] This invention relates to the field of spatial irregular-shaped terrazzo construction technology, and in particular to a process for manufacturing and installing spatial irregular-shaped terrazzo. Background Technology

[0002] With the continuous enrichment of architectural decoration forms, decorative products with curved surfaces, arc surfaces, and other spatial irregular structures are gradually increasing. Terrazzo, due to its good decorative effect, is also being used on walls, ceilings, and other decorative structures with spatial irregular curved surfaces.

[0003] There is currently no relevant construction technology for large, irregularly shaped terrazzo stones. Summary of the Invention

[0004] The purpose of this invention is to solve the problems pointed out in the background art, and to propose a process for manufacturing and installing spatial irregularly shaped grinding stones.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A process for manufacturing and installing irregularly shaped terrazzo in a spatial arrangement includes the following steps:

[0007] s1. Based on the design shape of the irregular curved surface of the product space, the product is divided into multiple independent unit blocks, and the grinding stone module is independently prepared according to the shape of each unit block;

[0008] s2. Construct the keel frame at the construction site;

[0009] s3. Hoist the grinding stone modules to the corresponding installation positions on the keel frame, and fix multiple grinding stone modules onto the keel frame using connecting rods to form a blank product;

[0010] s4. Modify and beautify the blank product to form a spatial irregular terrazzo product.

[0011] The present invention proposes a manufacturing and installation process for spatial irregular-shaped terrazzo, which has the following advantages: By using this process, the spatial irregular-shaped terrazzo product is divided into multiple independent terrazzo modules for manufacturing and installation. Compared with manufacturing irregular-shaped terrazzo as a whole, the size and weight of individual components can be reduced, making it easier to process, transport, and hoist on site. On the construction site, only a keel frame needs to be built first, and then each terrazzo module is installed onto the keel frame through connecting rods. This reduces the difficulty of hoisting and installing large irregular-shaped terrazzo as a whole. At the same time, it can be manufactured independently according to the actual shape of each unit block, improving the manufacturing and installation efficiency of spatial irregular-shaped terrazzo.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Reference Figures 1-3 A process for manufacturing and installing irregularly shaped terrazzo in a spatial arrangement includes the following steps:

[0018] s1. Based on the design shape of the irregular curved surface of the product space, the product is divided into multiple independent unit blocks, and the grinding stone module 3 is independently prepared according to the shape of each unit block;

[0019] s2. Construct the keel frame 1 at the construction site;

[0020] s3. Hoist the grinding stone module 3 to the corresponding installation position of the keel frame 1, and fix multiple grinding stone modules 3 onto the keel frame 1 through the connecting rod 2 to form a blank product;

[0021] s4. Modify and beautify the blank product to form a spatial irregular terrazzo product.

[0022] This process involves dividing the spatial irregular-shaped terrazzo product into multiple independent terrazzo modules 3 for manufacturing and installation. Compared to manufacturing irregular-shaped terrazzo as a whole, this reduces the size and weight of individual components, facilitating processing, transportation, and on-site hoisting. On-site, only the keel frame 1 needs to be erected first, and then each terrazzo module 3 is installed onto the keel frame 1 via connecting rods 2. This reduces the difficulty of hoisting and installing large irregular-shaped terrazzo as a whole. At the same time, it allows for independent manufacturing based on the actual shape of each unit block, improving the efficiency of manufacturing and installing spatial irregular-shaped terrazzo.

[0023] As one method of preparing grinding stone module 3:

[0024] a1. Weld the support frame 10 according to the shape of the unit block;

[0025] a2. Fix the mesh plate on the outer surface of the support frame 10;

[0026] a3. Lay the terrazzo paving layer 9 on the mesh board;

[0027] a4. After the terrazzo paving layer 9 is cured, terrazzo module 3 is formed.

[0028] When using the above preparation method, firstly, a support frame 10 is welded according to the shape of the unit block. Then, a mesh plate is fixed on the outer surface of the support frame 10 and a terrazzo paving layer 9 is laid. After the terrazzo paving layer 9 is cured, a terrazzo module 3 is formed. The support frame 10 can provide overall support for the terrazzo paving layer 9, and the mesh plate can support and limit the terrazzo material, so that the terrazzo module 3 has good overall structural strength. At the same time, the terrazzo module 3 can be prefabricated independently before construction, without being limited by the space and curved surface installation conditions of the construction site, which facilitates batch production and subsequent hoisting and installation.

[0029] During the assembly of large curved surface products, due to the product's large overall weight and uneven weight distribution across different areas, coupled with variations in support conditions and structural stiffness at different installation locations, uneven stress distribution can easily occur among multiple connection points. When the load borne by a local connection exceeds its bearing capacity, local deformation can easily occur, potentially leading to overall instability or even collapse, affecting the product's assembly accuracy and operational safety. To address this issue, one implementation method is as follows:

[0030] The steps following s1 are as follows:

[0031] b1. Perform multi-point weighing or multi-point suspension tests on the grinding stone module 3 as a whole, determine the spatial center of gravity of the grinding stone module 3 based on the load data obtained from the test, and fix the ball joint seat 5 on the back of the grinding stone module 3 at the position corresponding to the center of gravity.

[0032] S3 also includes the following steps:

[0033] b2. Connecting rod 2 includes main rod 4;

[0034] Install a ball joint 6 on the ball joint seat 5, and connect the main rod 4 in the connecting rod 2 to the ball joint seat 5 through the ball joint 6. The other end of the main rod 4 is fixed to the keel frame 1, so that the main rod 4 forms the main support for the grinding stone module 3, and the main rod 4 can slightly change the support angle relative to the grinding stone module 3.

[0035] By arranging the main support position based on the actual measured center of gravity, the force direction of the main support is made closer to the force direction of the grinding module 3 itself, which can reduce the overturning tendency and local stress caused by eccentric support. At the same time, the rotation of ball joint 6 is used to adapt to the slight posture changes that occur during installation, avoiding excessive bending constraints on the main rod 4, so that the grinding module 3 can maintain a relatively stable stress state during hoisting and initial installation, providing a reliable basis for subsequent stress adjustment of each connection position.

[0036] The connecting rod 2 includes a secondary rod 8; multiple strain gauges 7 are arranged circumferentially around the main rod 4, and secondary rods 8 are arranged in multiple areas outside the center of gravity of the grinding stone module 3. The grinding stone module 3 is temporarily connected to the keel frame 1 through the secondary rods 8. The secondary rods 8 can adjust the connection position and installation angle; the secondary rods 8 are rods with adjustable length. By changing the length of the secondary rods 8, the connection position with the support frame 10, and the connection angle with the keel frame 1, the load transmitted from the corresponding area of ​​the grinding stone module 3 to the keel frame 1 can be changed; multiple reserved holes 11 are provided on the grinding stone module 3. The multiple reserved holes 11 are distributed around the center of gravity of the grinding stone module 3. One end of the secondary rod 8 can be temporarily connected to the reserved holes 11 at different positions to change the connection position of the secondary rod 8 on the grinding stone module 3.

[0037] By adjusting the length, connection position, and installation angle of the auxiliary rods 8, the load transmitted from different areas of the grinding stone module 3 to the keel frame 1 can be changed, so that some of the load originally concentrated on the main rod 4 can be gradually distributed to multiple auxiliary rods 8. At the same time, by using multiple strain gauges 7 to detect the strain at different circumferential positions of the main rod 4, the current load bias can be intuitively determined, and the appropriate reserved hole 11 can be selected to adjust the position of the auxiliary rods 8, thereby making the stress on each area of ​​the grinding stone module 3 more uniform, reducing local load concentration, and improving the stability during the installation process.

[0038] S3 also includes the following steps: using the main rod 4 as the initial main load-bearing structure, while keeping the spatial posture of the grinding module 3 basically unchanged, gradually adjust the connection position and installation angle of each auxiliary rod 8, and detect the strain change at different circumferential positions of the main rod 4 through multiple strain gauges 7. Based on the detection results of different strain gauges 7, determine the load bias of the grinding module 3, and adjust the auxiliary rods 8 at the corresponding positions to distribute part of the load from the main rod 4 to the auxiliary rods 8; repeatedly adjust each auxiliary rod 8 to make the detected strain values ​​of multiple strain gauges 7 around the main rod 4 tend to be balanced, and keep the grinding module 3 in a predetermined spatial posture. When the strain difference between multiple strain gauges 7 reaches a preset range, determine the connection position, length and installation angle of each auxiliary rod 8 as the final installation parameters.

[0039] Set up the final bracket according to the determined connection position, length and installation angle of each auxiliary rod 8. Without changing the spatial posture of the grinding stone module 3 and the installation position of each auxiliary rod 8, replace the auxiliary rod 8 with the final bracket and weld or bolt it to the keel frame 1 so that the grinding stone module 3 and the keel frame 1 form a final fixed connection. After the final fixing is completed, remove the strain gauge 7 of the main rod 4.

[0040] By arranging the main support position based on the actual measured center of gravity, the force direction of the main support is made closer to the force direction of the grinding module 3 itself, which can reduce the overturning tendency and local stress caused by eccentric support. At the same time, the rotation of ball joint 6 is used to adapt to the slight posture changes that occur during installation, avoiding excessive bending constraints on the main rod 4, so that the grinding module 3 can maintain a relatively stable stress state during hoisting and initial installation, providing a reliable basis for subsequent stress adjustment of each connection position.

[0041] Furthermore, this process uses multiple strain gauges 7 on the main rod 4 to reflect the stress changes of the main rod 4 in different circumferential directions, and judges the current load bias of the grinding module 3 by the strain difference at different positions. When the load in a certain direction is relatively concentrated, the auxiliary rod 8 near that area can change the force transmission path in that area by changing the connection position, installation angle and its own length, so that part of the load is transferred from the main rod 4 to the corresponding auxiliary rod 8, and further transmitted to the keel frame 1. Since the spatial posture of the grinding module 3 remains basically unchanged during the adjustment process, the auxiliary rod 8 is mainly used to change the force distribution, and will not significantly change the installation posture of the grinding module 3 due to the adjustment of the support relationship, thereby gradually reducing the local stress concentration of the main rod 4.

[0042] As the auxiliary rods 8 are continuously adjusted, the strain at different positions around the main rod 4 gradually converges, indicating that the load previously biased in one direction has been redistributed. When the strain difference between multiple strain gauges 7 reaches the preset range, it can be considered that the eccentric load on the main rod 4 has been effectively reduced, and the auxiliary rods 8 have formed an auxiliary bearing relationship that matches the actual weight distribution of the grinding stone module 3. This method does not directly determine each connection point based on theoretical calculations or fixed installation positions, but rather adjusts on-site according to the actual stress state of the grinding stone module 3 after hoisting. Therefore, it can adapt to the actual changes caused by the weight distribution of irregularly shaped grinding stones, installation posture, and local stiffness differences of the keel frame 1, improving the accuracy of stress adjustment.

[0043] Once the stress state is determined, the temporary connection relationship is converted into a final fixed structure without changing the current spatial orientation and connection position. This is equivalent to directly solidifying the verified and reasonable stress path, ensuring that the grinding stone module 3 maintains the load distribution relationship established during adjustment in its final installed state. This reduces secondary off-center loading caused by changes in stress state due to re-determining connection positions or disassembly / reassembly. Consequently, the load on the grinding stone module 3 can be rationally distributed from the main support to multiple auxiliary supports, reducing load concentration at local connection points and the resulting risk of local deformation and overall instability, thus improving the overall stability of the large, irregularly shaped grinding stone after installation.

Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes to the technical solution and inventive concept of the present invention within the scope of the technology disclosed in the present invention should be covered within the scope of protection of the present invention.
