Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of ground hardening, and in particular, to an SMC composite material assembled ground hardening. Background Art

[0002] In the field of infrastructure construction and maintenance of outdoor trackside signal equipment on conventional and high-speed ballasted trackbeds of railways, ground hardening is a key link to ensure the stable operation of signal equipment. There are two main traditional methods of ground hardening. One is to use cement to make hardened ground. The construction process is extremely cumbersome. First, the construction site needs to be leveled and compacted in a complex manner to ensure the stability of the foundation. Subsequently, the formwork needs to be built, raw materials such as cement and sand and gravel need to be prepared, and they need to be precisely mixed in a certain proportion. The mixed cement slurry is then poured into the formwork. After a long period of vibration, leveling, maintenance and other steps, the construction of the hardened ground can be completed. This process not only consumes a lot of manpower, material resources and time, but also once the cement hardened ground is damaged, it is difficult to repair, and it needs to be partially or even large-scale demolished and re-poured. Another common method is to use a variety of panels for assembly, which increases the complexity and cost of manufacturing, processing and construction.

[0003] With the rapid development of railway construction and the continuous improvement of the requirements for signal equipment maintenance efficiency, the traditional ground hardening method has become difficult to meet the efficient, fast and reliable construction and maintenance needs of modern railway projects due to its cumbersome and inconvenient characteristics.

DETAILED DESCRIPTION The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than to limit the present disclosure.

[0019] In order to simplify the drawings, only the parts related to the disclosure are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0020] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this disclosure can be understood according to specific circumstances.

[0021] In the present disclosure, unless otherwise expressly specified and limited, a first feature being “above” or “below” a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figure 1 to Figure 9 As shown, it shows the ground assembly 2 in one embodiment of the present disclosure.

[0025] In some examples, multiple substrates 1 are spliced ​​together to form a ground assembly 2, and the substrate 1 has a protrusion 1 3 and a protrusion 2 4, which are respectively located on both sides of the substrate 1 and are staggered along the height of the substrate 1; the protrusion 1 3 has at least two mounting holes 5; the protrusion 2 4 has at least one mounting hole 5; when two substrates 1 are spliced ​​parallel or vertically, the protrusion 1 3 and the protrusion 2 4 are parallel or vertically overlapped with each other, and at least one mounting hole 5 of the protrusion 2 4 is connected to at least one mounting hole 5 of the protrusion 1 3.

[0026] In this example, only one base 1 can be used to complete the splicing of the ground assembly 2 in different ways, which can be combined into a variety of sizes and models, and is easy to install. Compared with the traditional method of assembling multiple panels, it simplifies the material management and construction process. Only one base 1 can be used to complete the splicing of the ground assembly 2 in different ways, which can be combined into a variety of sizes and models, and is easy to install. Compared with the traditional method of assembling multiple panels, it has achieved significant simplification in terms of material management and construction process. Traditional assembly of multiple panels requires the purchase, storage and management of multiple panels of different specifications, models and materials. Each panel has its own unique performance and use, which requires managers to understand many panels, increasing the difficulty of management. Now only one base 1 needs to be managed, which greatly reduces the types of materials that need to be recognized and controlled, and reduces the complexity of management. When assembling multiple panels, due to the wide variety of panels, each panel needs to have a certain inventory to meet construction needs, which not only takes up a lot of storage space, but also easily leads to inventory backlog or out of stock. A single base 1 facilitates inventory management, and more accurately controls the inventory quantity according to the construction progress and needs, reduces storage costs, and reduces capital occupation. During the construction process, the operation process is simplified. In traditional construction, different board materials need to be spliced ​​in different connection methods and processes according to the characteristics of the board materials. Workers need to master a variety of construction skills and operating specifications. The construction connection is complicated and construction errors are prone to occur. Now using a single substrate 1, no matter what splicing method is used, workers only need to be familiar with the construction method of one material, which reduces the construction difficulty, improves construction efficiency, and reduces quality problems and construction delays caused by construction errors. Moreover, the single substrate 1 can be combined into a variety of sizes and models to meet the needs of different construction scenarios. There is no need to frequently replace and adjust the board as in the traditional way, which further simplifies the construction process.

[0027] Select appropriate SMC composite materials as the raw materials of the matrix 1. SMC composite materials have good mechanical properties, corrosion resistance, resistance to multiple climate environments and insulation, and are lightweight and suitable for ground hardening structures. According to the design requirements, the SMC composite materials are cut and pre-processed to ensure that their quality and size meet the processing requirements.

[0028] Select appropriate SMC composite materials as the raw materials of the substrate 1. SMC composite materials have good mechanical properties, corrosion resistance, resistance to multiple climate environments and insulation, and are lightweight and suitable for ground hardened structures. According to the design requirements, the SMC composite materials are cut and pre-processed to ensure that their quality and size meet the processing requirements.

[0029] like Figure 7 and Figure 8 As shown, the two sides of the base 1 are provided with a protrusion 1 3 and a protrusion 2 4, and the two protrusions are arranged alternately along the height direction of the base 1. This staggered arrangement provides a structural basis for subsequent different splicing methods, so that the protrusions can be reasonably overlapped during parallel splicing and vertical splicing, ensuring the tightness and stability of the splicing.

[0030] There are at least two mounting holes on the protrusion 3, and preferably, three mounting holes can be provided. Figure 8 As shown, there is at least one mounting hole 5 on the protrusion 2 4, and preferably, two can be provided, such as Figure 7 and Figure 8 These installation channels 5 are interconnected in different splicing modes for subsequent installation of connectors, thereby achieving a firm connection between the substrates 1 .

[0031] like Figure 5 and Figure 6 As shown, when two substrates 1 are spliced ​​in parallel, the protrusion 1 3 of one substrate 1 overlaps with the protrusion 2 4 of the other substrate 1 in parallel, and the two mounting holes 5 of the protrusion 1 3 can be connected with the two mounting holes 5 of the protrusion 2 4, ensuring the integrity and stability of the ground in this direction.

[0032] like Figure 3 and Figure 4 As shown, when two substrates 1 are vertically spliced, the protrusion 1 3 of one substrate 1 and the protrusion 2 4 of the other substrate 1 overlap each other vertically, and the protrusion 1 3 still has two installation channels 5 that can be connected with the two installation channels 5 of the protrusion 2 4. Through this vertical splicing method, the splicing requirements in different directions of the ground can be met, and various complex construction site layouts can be adapted.

[0033] The mold can be manufactured by mechanical processing and surface treatment processes to ensure that it can withstand the pressure and temperature during the molding process. For example, the pre-treated SMC composite material is placed in the mold and molded under certain temperature and pressure conditions. During the molding process, the SMC composite material flows and solidifies in the mold to form a matrix 1 with the desired shape and size. By controlling the process parameters such as molding temperature, pressure and time, the density, strength and surface quality of the matrix 1 can be guaranteed. After the matrix 1 is formed, the mounting channel 5 is processed on the protrusion 1 3 and the protrusion 2 4 by drilling and other processing processes. During the processing, the position accuracy and dimensional accuracy of the channel must be ensured to ensure that the channel can be accurately connected during splicing. The processed matrix 1 is quality inspected to check whether its performance indicators such as dimensional accuracy, surface quality, and strength meet the design requirements. The unqualified matrix 1 is repaired or scrapped to ensure that the quality of the matrix 1 put into use is qualified.

[0034] In summary, this example proposes a solution that only one base 1 is needed to achieve horizontal and vertical overlap, without the need to prepare multiple different types of plates, reducing the types and quantities of materials, and reducing the difficulty and cost of material management. Construction workers do not need to spend a lot of time and energy to distinguish and select different plates, thereby improving construction efficiency.

[0035] The parallel and vertical splicing methods can be flexibly selected according to the needs of the actual construction site, and can adapt to various complex ground layouts. During the construction process, workers only need to splice the base 1 according to the design requirements. The operation is simple and easy to understand, which reduces the requirements on the technical level of construction workers.

[0036] The protrusion 1 3 and the protrusion 2 4 are arranged in a staggered manner along the height of the base 1, and can form a mutually nested structure when spliced, thereby increasing the connection area and friction between the bases 1, and improving the tightness and stability of the splicing. Whether it is parallel splicing or vertical splicing, the overall structure of the ground can be ensured to be firm and not prone to loosening and deformation. Through the connection of the installation channel 5, the bases 1 can be firmly connected together using connecting parts (such as bolts, pins, etc.). This connection method can effectively transfer loads, enhance the bearing capacity of the ground, and ensure the stability of the ground during long-term use.

[0037] Since the structure of the base 1 is simple and the splicing method is uniform, if a part of the ground is damaged, only the corresponding base 1 needs to be replaced. The replacement process is relatively simple, and there is no need to carry out large-scale demolition and repair of the entire ground, which reduces maintenance costs and time costs.

[0038] In some examples, the substrate 1 further has a connection portion 10 and a connection portion 3 12; the connection portion 10 and the connection portion 3 12 are respectively located on both sides of the substrate 1; the connection portion 10 includes a plate portion 1001 and a plate portion 1002 that are connected to each other, the plate portion 1001 is horizontally arranged, and the plate portion 2 1002 extends to one side of the height of the plate portion 1001; the plate portion 1001 and the connection portion 3 12 are alternately arranged along the height of the substrate 1, and the height of the plate portion 2 1002 is consistent with that of the connection portion 3 12; when two substrates 1 are spliced ​​in parallel, the plate portion 2 1002 abuts against the connection portion 3 12.

[0039] In this example, Figure 5 As shown, a structure is proposed in which the plate part 2 1002 abuts against the connecting part 3 12 when two base bodies 1 are parallelly spliced. The plate part 2 1002 and the connecting part 3 12 have the same height and abut against each other, which provides a structural basis for adding a connecting piece at the abutting position for fixing.

[0040] The abutment structure between the second plate portion 1002 and the third connection portion 12 provides additional connection points and support surfaces for the parallel splicing of the base 1, making the splicing more solid and improving the overall stability of the ground assembly 2. When subjected to external forces, such as vibration and impact caused by train travel, the abutment structure can effectively disperse stress and avoid stress concentration at a certain point or area, thereby extending the service life of the ground hardened structure.

[0041] During the construction process, the height of the second plate part 1002 and the connection part 3 12 are consistent and the structural design of abutting each other makes it easier for workers to perform the splicing operation of the base 1. Preliminary positioning can be performed through the abutment surface, and then subsequent connection and fixing work can be performed, which improves the construction efficiency. In terms of maintenance, if a base 1 is damaged, due to the existence of the connection part, it is also more convenient to disassemble and replace the base 1, reducing maintenance costs and time.

[0042] In some examples, the second plate portion 1002 has a first through hole 14 ; the third connecting portion 12 has a first channel 16 , and when the second plate portion 1002 abuts against the third connecting portion 12 , the first channel 16 is connected to the first through hole 14 .

[0043] The first hole 16 matches the first through hole 14 of the second plate portion 1002 in position and size. When the two substrates 1 are parallelly spliced ​​and the second plate portion 1002 abuts against the third connection portion 12, the first hole 16 can be accurately connected with the first through hole 14 to form a complete through passage. The first hole 16 is a blind hole or a through hole, preferably a blind hole.

[0044] After the first hole 16 is connected to the first through hole 14, the connection strength of the two bases 1 when parallel spliced ​​can be further strengthened by inserting a connecting piece (such as a pin, a bolt, etc.). This physical connection method can effectively prevent the base 1 from being relatively displaced due to external forces (such as ground vibration, horizontal tension, etc.) during use, thereby ensuring the integrity and stability of the ground hardened structure.

[0045] The connected channel structure provides clear and convenient operation instructions for construction personnel. At the construction site, workers can easily determine whether the abutment between the second plate portion 1002 and the third connection portion 12 is in place by observing whether the first channel 16 and the first through hole 14 are aligned, which reduces the construction difficulty and improves the construction efficiency. At the same time, this connected structure also facilitates the installation of the connector. Construction personnel can accurately insert the connector into the connected channel without additional complicated positioning operations.

[0046] For different application scenarios and engineering requirements, different types and specifications of connectors can be selected and inserted into the connected channels according to actual conditions. For example, in heavy-duty railway areas with high requirements for structural strength, high-strength bolts can be selected as connectors; and in some temporary projects with high requirements for installation speed, pins that are easy to install and disassemble can be selected. This flexibility enables ground hardening structures to better adapt to various complex and changing engineering environments. During the use of the ground hardening structure, if a substrate 1 is damaged and needs to be replaced, it is more convenient to disassemble the connector due to the communication structure of the first channel 16 and the first through hole 14. The construction personnel can quickly take out the connector, then remove the damaged substrate 1 and replace it with a new substrate 1, which reduces maintenance time and cost and improves the maintainability of the entire ground hardening system. In some examples, such as Figure 4 and Figure 5 The base 1 also has a connection part 2 11 and a connection part 4 13; the connection part 10 and the connection part 2 11 are arranged at intervals along the height of the base 1; the connection part 2 11 includes a plate part 3 1101 and a plate part 4 1102 connected to each other, the plate part 3 1101 is arranged horizontally, and the plate part 4 1102 extends to one side of the height of the plate part 3 1101; the plate part 3 1101 and the connection part 4 13 are arranged alternately along the height of the base 1, and the height of the plate part 4 1102 and the connection part 4 13 is consistent; when the two bases 1 are spliced ​​in parallel, the plate part 4 1102 abuts against the connection part 4 13. The plate part 4 1102 has a second through hole 15; the connection part 4 13 has a third channel 18, and when the plate part 4 1102 abuts against the connection part 4 13, the third channel 18 is connected to the second through hole 15.

[0047] The connection part 10 and the connection part 2 11 are arranged at intervals along the height of the base 1, forming a layered connection structure. The connection part 2 11 also includes a plate part 3 1101 and a plate part 4 1102. The plate part 3 1101 is arranged horizontally, and the plate part 4 1102 extends to one side of the height of the plate part 3 1101. This is the same as the structural design concept of the connection part 10, ensuring the consistency and coherence of the structural design. The plate part 3 1101 and the connection part 4 13 are arranged alternately along the height of the base 1, and the plate part 4 1102 is at the same height as the connection part 4 13. This layout method enables the plate part 4 1102 to accurately abut against the connection part 4 13 when the two bases 1 are spliced ​​in parallel, forming a tight connection structure.

[0048] The plate portion 1102 is provided with a second through hole 15, and the connecting portion 13 is correspondingly provided with a third channel 18. When the plate portion 1102 and the connecting portion 13 are in contact, the channels of the two are connected and aligned to form a through channel. This channel connection and alignment structure corresponds to the channel connection and alignment structure of the plate portion 1002 and the connecting portion 12, further improving the connection system between the substrates 1.

[0049] The second connection part 11 and the fourth connection part 13 and the abutting structure therebetween increase the contact area and connection points when the two base bodies 1 are parallelly spliced. The multiple connection points work together to more effectively disperse and withstand various external forces, such as uneven settlement of the ground, impact force generated by train operation, etc., thereby significantly improving the overall stability and bearing capacity of the ground hardened structure.

[0050] In some examples, such as Figure 7 and Figure 8 As shown, the base 1 also has a connecting slot 1 20 and a connecting slot 21, and the connecting slot 1 20 and the connecting slot 21 are arranged at intervals in height of the base 1; the cross-sectional shape and height of the connecting slot 1 20 are consistent with the cross-sectional shape and height of the connecting part 10; the cross-sectional shape and height of the connecting slot 21 are consistent with the cross-sectional shape and height of the connecting part 2 11; when the two bases 1 are vertically spliced, the connecting part 10 is plug-connected with the connecting slot 1 20, the connecting part 3 12 is overlapped with the plate part 1001, and the connecting part 2 11 is plug-connected with the connecting slot 21, and the connecting part 4 13 is overlapped with the plate part 4 1102; when the two bases 1 are horizontally spliced, the connecting slot 1 20 and the connecting slot 2 21 are not plug-connected with the connecting part 1 10 and the connecting part 2 11, and are in an empty state, which is used to connect the inside of the ground assembly 2 with the outside of the ground assembly 2, and can be used as a drainage outlet.

[0051] The connecting notch 1 20 and the connecting portion 1 10 , as well as the connecting notch 2 21 and the connecting portion 2 11 , are consistent in cross-sectional shape and height, providing a precise docking foundation for the connection between the substrates 1 .

[0052] like Figure 3 and Figure 4 As shown, when two base bodies 1 are vertically spliced, the connection part 10 is inserted into the connection slot 1 20, the connection part 2 11 is inserted into the connection slot 21, and the connection part 3 12 overlaps with the plate part 1 1001, and the connection part 4 13 overlaps with the plate part 4 1102. This combined connection method fixes the vertically spliced ​​base bodies 1 from multiple dimensions, forming a stable vertical connection structure, which greatly increases the stability and firmness of the splicing.

[0053] like Figure 5 and Figure 6 As shown, during horizontal splicing, the connection slot 1 20 and the connection slot 2 21 are in an empty state and do not participate in the connection, but at this time they can connect the inside and the outside of the ground assembly 2.

[0054] In summary, in vertical splicing, the plug-in connection between the connecting part and the connecting groove and the overlapping connection between the connecting parts increase the connection points of the base 1 in the vertical direction, so that it can effectively resist the vertical shear force, tension and various stresses caused by the uneven ground, thereby improving the stability of the entire ground hardening structure in the vertical direction, ensuring that the ground assembly 2 can still maintain structural integrity under complex stress conditions.

[0055] The second plate portion 1002 extends to one side relative to the first plate portion 1001, which increases the overall structural strength of the connection portion 10 and provides a basis for the horizontal splicing of the two bases 1. The two bases 1 can not only be horizontally connected through the connection portion 10 and the connection portion 3 12, but also be vertically connected through the connection portion 10 and the connection portion 3 12, and can adapt to structures in different connection states. When vertically connected, the plate portion 1001 and the connection portion 3 12 overlap up and down, and the up and down overlap can significantly enhance the bearing capacity of the connection part, so that the force in the vertical direction can be evenly dispersed, avoiding stress concentration at a certain point, thereby greatly improving the vertical stability of the entire structure. The stability of the direction is ensured, and the connecting part 10 is inserted into the connecting groove 20, which constitutes a stable connection foundation at the vertical angle, which not only further strengthens the connection from the mechanical structure, but also solves the sealing problem. When connected in parallel, the two substrates 1 are horizontally connected through the connecting part 10 and the connecting part 3 12, and the connecting groove 20 and the connecting groove 21 are not vacant, and can be used as drainage outlets. In an environment prone to water accumulation such as outdoor railroad ballast bed, the accumulated water can be discharged through the vacant connecting grooves, avoiding the erosion of the ground hardened structure and signal equipment by ground water, extending the service life of the structure, and also ensuring the normal operation of the signal equipment.

[0056] The design of precise matching between the connection notch and the connection part reduces the construction difficulty, improves the construction efficiency, and reduces the problem of structural instability caused by construction errors. This design, which can realize both vertical splicing and drainage function during horizontal splicing, enables the ground hardening structure to better adapt to different laying requirements and complex environmental conditions. Whether in open-air sites that require drainage or in vertical connection scenarios that require high structural stability, the structure can play its advantages and show good adaptability. In some examples, the connection part three 12 also has a second channel 17; when the connection part one 10 is plugged into the connection slot one 20, the second channel 17 is connected to the first through hole 14; the connection part four 13 also has a fourth channel 19; when the connection part two 11 is plugged into the connection slot two 21, the fourth channel 19 is connected to the second through hole 15.

[0057] Through the connection of these channels, when the base 1 is vertically spliced, not only the physical plug-in and overlap of the connecting part and the connecting groove are realized, but also a multi-directional connection reinforcement system is formed through the connection and alignment of the channels, which enhances the structural stability of the vertical splicing and makes the connection between each base 1 in the vertical direction tighter and more stable.

[0058] After the holes are connected and aligned, connectors (such as bolts, pins, etc.) can be inserted to further strengthen the connection strength between the connection part and the connection notch. Compared with simple plug-in and overlap, this method of inserting connectors through the hole can effectively resist external forces in multiple directions, especially at vertical joints, greatly improving the tensile and shear resistance of the structure, ensuring that the ground hardened structure can maintain good stability in the long-term use process when facing complex external forces such as train operation vibration and ground settlement, reducing the risk of structural damage caused by loose connections.

[0059] The design of hole connection and alignment provides construction workers with clearer splicing alignment marks. During the construction process, construction workers can judge whether the connection part and the connection slot are accurately plugged in by observing whether the hole is aligned, which helps to improve the accuracy of construction. At the same time, this design also facilitates the installation of connectors, reduces construction difficulty, and improves construction efficiency. In some examples, the protrusion 1 3 also has a first stop 22, which is arranged at an angle and arranged at a distance on one side of the mounting hole 5 of the protrusion 1 3; the protrusion 2 4 also has a second stop 23, which is arranged at an angle and arranged at a distance on one side of the mounting hole 5 of the protrusion 2 4 in the height direction.

[0060] The first stopper 22 is arranged on the protrusion 3, which is arranged obliquely and spaced apart on one side of the height direction of the installation channel 5. This oblique arrangement and spaced apart distribution ensure that the first stopper 22 does not affect the normal use of the installation channel 5, but can better block impurities or guide water flow to a certain extent, thereby protecting the channel, and can also enhance the structural strength of the protrusion 3 to a certain extent.

[0061] The second stopper 23 of the protrusion 24 is also arranged obliquely and spaced apart on one side of the height direction of the mounting hole 5. Similar to the first stopper 22, the design of the second stopper 23 is also based on the optimization of the structure of the protrusion 24 and the supplement of the related functions of the mounting hole 5. Figure 8 As shown, from the overall structure point of view, the first stopper 22 and the second stopper 23 ensure the consistency and coordination of the structures on both sides of the base 1, which helps to achieve better docking and stability during the splicing process.

[0062] The inclined design of the first stopper 22 and the second stopper 23 is conducive to guiding rainwater to flow down along the inclined surface of the stopper, and preventing liquid from accumulating around the installation channel 5. This can not only prevent the channel from rusting and corroding due to water accumulation, affecting the installation and structural stability of the connector, but also prevent foreign matter (such as dust, small particles, etc.) from entering the channel, ensuring the cleanliness of the installation channel 5, providing convenience for subsequent connection operations through the installation channel 5, and extending the service life of the structure.

[0063] The stoppers are spaced and distributed on one side of the height direction of the installation channel 5. From a mechanical point of view, the structural strength and rigidity of the protrusion are increased. When the base 1 is subjected to external force, the stoppers can share part of the stress, especially after being spliced ​​with other bases 1, the stoppers can cooperate with the installation channel 5 and the connectors to jointly resist the external force, reduce the risk of structural damage caused by stress concentration, and further improve the stability of the entire ground hardened structure under different working conditions.

[0064] In some embodiments, the base 1 further has a splicing protrusion 24 located on one side of the base 1 in the height direction.

[0065] In addition to horizontal or vertical splicing at the same height, the base 1 can also be spliced ​​at different heights through the splicing protrusions 24, expanding the construction method of the ground hardening structure. Specifically, Figure 1 and Fig. 9As shown. In actual application scenarios, if there are undulating terrain, basic conditions of different heights or special functional requirements, the splicing height of the base 1 can be flexibly adjusted according to the specific situation, so that the ground hardened structure can better adapt to the complex and changeable environment, thereby improving the applicability of the structure. By splicing at different heights, space can be used more reasonably. For example, in some venues with multi-level functional requirements, the ground hardened structure can use the splicing protrusions 24 to achieve platform construction at different heights, meet the needs of installation of different equipment or personnel activities, and improve the efficiency of ground space use.

[0066] In some embodiments, the base 1 further has a floor mounting strip 25 which is arranged horizontally and on which the floor can be mounted; the covering portion 26 is located on one side of the floor mounting strip 25 in the height direction and is used to cover the floor mounting strip 25 .

[0067] The floor installation strip 25 is horizontally arranged on the base 1. This design provides a stable bearing structure for the installation of the floor. Its horizontal arrangement helps to ensure the flatness of the floor after installation, so that the floor can be evenly stressed and avoid deformation and damage of the floor caused by uneven installation surface.

[0068] The cover portion 26 is located on one side of the height direction of the floor mounting strip 25, and it is closely matched with the floor mounting strip 25. The main function of the cover portion 26 is to cover the floor mounting strip 25. From the overall structure, it improves the appearance of the base 1 and also provides a certain degree of protection for the floor mounting strip 25.

[0069] The floor installation strips 25 provide a clear position and support for the installation of the floor, and the construction workers can directly install the floor on them, which simplifies the installation process and improves the installation efficiency. The horizontally arranged installation strips can evenly distribute the weight of the floor, enhance the stability of the floor after installation, and make the floor less likely to loosen or warp during long-term use.

[0070] The cover portion 26 covers the floor mounting strip 25, making the floor as a whole look neater and more beautiful, and preventing the mounting strip from being directly exposed to the outside and affecting the visual effect. At the same time, the cover portion 26 can prevent dust, debris, etc. from accumulating on the floor mounting strip 25, reduce erosion and damage to the mounting strip due to external factors, extend the service life of the floor mounting strip 25, and thus ensure the long-term stability of the floor mounting structure.
