Description

Technical Field

[0001] This application relates to the field of building foundation technology, and in particular to a post-cast strip force transmission structure integrating high-performance alloy steel and composite materials. Background Technology

[0002] In the field of building foundation technology, the construction of the main structural slab and floor slabs is crucial. With the continuous development of the construction industry, the requirements for the safety, stability, and construction efficiency of building structures are increasing. In the construction process, it is common to pour the main structural slab and floor slabs in sections or to set up post-pouring strips. This not only relates to the integrity of the overall building structure but also has a significant impact on the safety and quality of the construction process. Reasonable construction methods and structural design can ensure that the building structure can withstand various loads during construction and use, guaranteeing the normal use of the building and the safety of personnel. In past construction, when encountering situations where the main structural slab and floor slab are poured in sections or post-pouring strips are set up, the common practice was to directly pour the concrete for the post-pouring strips. This method is simple and direct, and can meet basic construction requirements to a certain extent. However, it lacks effective force transmission and support structure design. Some construction may simply be based on the actual conditions of the construction site, combined with the concrete pouring special construction plan and the design requirements of the foundation pit support internal support removal construction plan, but it does not fundamentally solve the structural stress and force transmission problems at the post-pouring strip. In addition, some construction companies may have tried temporary support measures to address structural stability issues during support removal, but these measures often lack systematicity and effectiveness. Due to the presence of the post-cast strip, the entire structural slab or floor slab cannot form a unified load-bearing structure. Moreover, when removing the supports within the foundation pit, the force transmission of the main structure may break at the post-cast strip, causing the basement structure to fail to provide effective support for the pit sidewalls, thus creating potential safety and quality hazards during construction. Utility Model Content

[0003] In order to improve the impact of the traditional direct pouring of post-cast strip concrete on the structural base plate and the safety and quality hazards that exist during the dismantling of supports, this application provides a post-cast strip force transmission structure integrating high-performance alloy steel and composite materials.

[0004] This application provides a post-cast strip force transmission structure integrating high-performance alloy steel and composite materials, employing the following technical solution:

[0005] A post-cast strip force transmission structure integrating high-performance alloy steel and composite materials includes a force transmission component, a stress monitoring component, and a head component made of lightweight composite material installed on a base plate or floor slab. At least one set of head components is installed on each end of the force transmission component. At least one set of stress monitoring components is installed on the body of the force transmission component near the end of each end. At least one set of fixing components connected to the base plate or floor slab is also provided on the body of the force transmission component near the end of each end, with one end of the fixing component fixedly connected to the force transmission component.

[0006] By adopting the above technical solutions, using I-beams made of high-performance alloy steel as force transmission components improves the durability and load-bearing capacity of the post-cast strip force transmission structure; using end plates made of lightweight composite materials as end components achieves lightweight design while maintaining or improving the strength and stability of the structure; installing stress monitoring components to monitor the stress state of the structure in real time improves the flexibility and adaptability of the structure; and fasteners can connect the force transmission components to the base plate or floor slab, making the entire structure's base plate or floor slab a whole under load, avoiding excessive local stress, enhancing the strength of the building structure, improving load-bearing capacity and deformation resistance, and reducing potential construction safety and quality hazards.

[0007] Optionally, each set of the end caps and force transmission components are connected by a first adhesive portion.

[0008] By adopting the above technical solutions, using high-performance alloy I-beams as force transmission components, intelligent sensors with strain gauges as stress monitoring components, and carbon fiber reinforced polymer end plates as end plates, the high strength, high toughness, and corrosion resistance of high-performance alloys and composite materials can be utilized to improve the durability and load-bearing capacity of the structure, thereby enhancing its strength and stability. Installing end plates at both ends of the force transmission components and connecting them with adhesive further ensures the stability of the connection between the force transmission components and the end plates. Erecting studs on the force transmission components to connect with the base plate or floor slab allows for secure fixation. Installing stress monitoring components on the force transmission components enables real-time monitoring of the structure's stress state, improving its flexibility and adaptability. The combined effect of these structures effectively supports the building structure, ensuring its stability and safety, forming the entire base plate or floor slab into a unified load-bearing unit, preventing excessive local stress, enhancing the strength of the building structure, improving its load-bearing capacity and deformation resistance, and reducing potential construction safety and quality hazards.

[0009] Optionally, each set of stress monitoring components and force transmission components are connected by a second adhesive part.

[0010] By adopting the above technical solutions, using high-performance alloys to prepare I-beams as force transmission components can improve the durability and load-bearing capacity of the structure; using lightweight composite materials to prepare end plates as end components can achieve lightweight design; stress monitoring components can monitor the stress state of the structure in real time, improving the flexibility and adaptability of the structure; fasteners connect the force transmission components to the base plate or floor slab; using adhesives to connect the stress monitoring components to the force transmission components can ensure that the stress monitoring components are firmly installed on the force transmission components, ensuring that they can accurately monitor the stress state of the force transmission components, further ensuring that the stress state of the post-cast strip force transmission structure can be grasped in real time and accurately, which is conducive to taking timely measures to ensure the stability and safety of the building structure.

[0011] Optionally, each set of fasteners includes multiple sets of fastening parts, which are installed at intervals on the force transmission component. One end of each set of fastening parts is fixedly connected to the force transmission component. Each set of fastening parts has a force-bearing part, which is located on the body of each set of fastening parts.

[0012] By adopting the above technical solution, multiple sets of spaced studs are installed at both ends of the force transmission component, and semi-circular protrusions are set on the surface of the studs. This can strengthen the connection between the force transmission component and the base plate or floor slab, making the structure more stable, better transmitting force, reducing excessive local stress, enhancing the strength of the building structure, improving the structural bearing capacity and deformation resistance, and reducing potential safety and quality hazards during construction.

[0013] Optionally, the force transmission member has a receiving portion, and the end cap has a hook portion that engages with the receiving portion.

[0014] By adopting the above technical solution, in the post-cast strip force transmission structure integrating high-performance alloy steel and composite materials, a receiving groove is opened on the I-beam, and an L-shaped hanging plate is protruded on the surface of the end plate. The two are interlocked and matched, which can further enhance the connection stability between the end plate and the force transmission component, thereby improving the stability and load-bearing capacity of the entire post-cast strip force transmission structure.

[0015] Optionally, the body of the force transmission component has a receiving portion, and the stress monitoring component has an insertion portion, which is inserted into the receiving portion and is elastic; the number of receiving portions is consistent with the number of stress monitoring components; the receiving portion has an opening, which gradually decreases in diameter along the surface of the force transmission component towards the body of the force transmission component, and the insertion portion is adapted to the receiving portion.

[0016] By adopting the above technical solution, using high-performance alloy I-beams as force transmission components, intelligent sensors with strain gauges as stress monitoring components, and carbon fiber reinforced polymer end plates as end plates, the durability and load-bearing capacity of the structure can be improved, achieving lightweight design while maintaining or improving the strength and stability of the structure. End plates and stress monitoring components are installed at both ends of the force transmission component, and studs are provided for connection to the base plate or floor slab, making the entire base plate or floor slab a unified load-bearing unit, avoiding excessive local stress. A tapered groove is provided in the body of the force transmission component as a receiving part, and the tapered plastic insertion rod of the stress monitoring component is inserted into the receiving part as an insertion part. The insertion part is elastic, and the diameter of the receiving part decreases along the surface of the force transmission component towards the body, with both fitting together. This facilitates stable installation of the stress monitoring component on the force transmission component, enabling better real-time monitoring of the structure's stress state, improving the structure's flexibility and adaptability, and reducing potential construction safety and quality hazards.

[0017] Optionally, the force transmission component has a force-enhancing part that increases friction.

[0018] By adopting the above technical solutions, H-beams made of high-performance alloys can be used as force transmission components to improve the durability and load-bearing capacity of the structure; end plates made of carbon fiber reinforced polymers can be used as end components to achieve lightweight design while maintaining or improving the strength and stability of the structure; intelligent sensors with strain gauges can be used as stress monitoring components to monitor the stress state of the structure in real time, improving the flexibility and adaptability of the structure; studs are used as fasteners to connect the force transmission components to the base plate or floor slab; small conical protrusions on the force transmission components increase the surface friction of the force transmission components, which can better transfer the force to the surrounding structure, further ensuring that the entire base plate or floor slab of the structure forms a whole under stress, enhancing the strength of the building structure, avoiding excessive local stress, and reducing potential safety and quality hazards during construction.

[0019] Optionally, the force transmission component is arranged in an I-shape.

[0020] By adopting the above technical solutions, the I-shaped force transmission components can better adapt to the force transmission requirements of the post-cast strip, effectively support the building structure, and transfer the forces borne by different parts of the building to the overall structure, so that the entire structural base plate or floor slab forms a whole under stress, avoid excessive local stress, enhance the strength of the building structure, and improve the structural bearing capacity and resistance to deformation.

[0021] In summary, this application has the following beneficial effects:

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a post-cast strip force transmission structure integrating high-performance alloy steel and composite materials, see [link to relevant documentation]. Figures 1 to 3 The structure includes a force transmission component 1, a stress monitoring component 2, and a head component 3 made of lightweight composite material, all installed on the base plate or floor slab. At least one set of head components 3 are installed on each end of the force transmission component 1. At least one set of stress monitoring components 2 are installed on the body of the force transmission component 1 near the ends. At least one set of fixing components 4 connected to the base plate or floor slab are also provided on the body of the force transmission component 1 near the ends. One end of the fixing component 4 is fixedly connected to the force transmission component 1. This structure allows for better force transmission at the post-cast strip, forming the entire base plate or floor slab into a single load-bearing unit. This effectively avoids excessive local stress, enhances the strength of the entire building structure, improves the load-bearing capacity and deformation resistance of the structure, and reduces potential safety and quality hazards during construction.

[0033] Specifically, the force transmission component 1 is arranged in an I-beam shape and includes an I-beam steel. The I-beam structural design of the force transmission component 1 provides excellent mechanical properties, effectively distributing and transmitting the load. Furthermore, the I-beam steel is made of high-strength low-alloy steel (HSLA steel), which possesses high strength, high toughness, corrosion resistance, and wear resistance, perfectly meeting the requirements for force transmission in post-cast strip structures. Of course, in some cases, other high-performance alloy steels can be selected to manufacture the I-beam steel according to actual needs.

[0034] See Figure 3 and Figure 4 The I-beam has a receiving portion 11, which is specifically a receiving groove on the I-beam for mating with the head member 3. The head member 3 includes a head plate and has a hanging portion 31 that engages with the receiving portion 11. The hanging portion 31 is specifically an L-shaped hanging plate that engages with the receiving groove. In addition, each set of head members 3 is connected to the force transmission member 1 through a first adhesive portion. Specifically, the first adhesive portion is a first adhesive that tightly bonds the head plate to the I-beam, ensuring a stable and reliable connection between them.

[0035] Meanwhile, the I-beam also has a force-enhancing part 12 that increases friction. Specifically, the force-enhancing part 12 is a small conical protrusion protruding from the surface of the I-beam. These small conical protrusions can increase the friction between the I-beam and the surrounding materials, making the force transmission more stable and reliable.

[0036] In addition, see Figure 2 and Figure 3 The body of the I-beam has a receiving portion; the stress monitoring component 2 has an insertion portion 21, which is inserted into the receiving portion and is elastic; the number of receiving portions is the same as the number of stress monitoring components 2; the receiving portion has a diameter, which gradually decreases along the surface of the force transmission component 1 toward the body of the force transmission component 1, and the insertion portion 21 is adapted to the receiving portion.

[0037] Specifically, the stress monitoring component 2 includes a stress sensor with a strain gauge. The receiving portion is specifically a tapered groove on the I-beam. The insertion portion 21 is specifically a tapered plastic insertion rod that inserts into the tapered groove. Furthermore, each set of stress monitoring components 2 is connected to the force transmission component 1 via a second adhesive portion. The second adhesive portion is specifically a second adhesive that further firmly adheres the smart sensor containing the strain gauge to the surface of the I-beam. As the I-beam deforms under stress, the sensitive grid of the strain gauge also undergoes the same deformation, causing its resistance to change proportionally to the strain of the specimen. This resistance change is converted into a voltage or current change through a certain measuring circuit and displayed and recorded by a display and recording instrument. This recorded data represents the magnitude of the strain of the I-beam, allowing observation of the stress state, deformation, and crack development of the entire post-cast strip force transmission structure.

[0038] See Figure 3 and Figure 4 Each set of fasteners 4 includes multiple sets of fastening parts 41, which are installed at intervals on the force transmission part 1. One end of each set of fastening parts 41 is fixedly connected to the force transmission part 1.

[0039] Each set of fasteners 41 includes studs, typically 22mm in diameter and L = 100mm in length, with a spacing of 100mm and four studs arranged on each side. These studs are installed at intervals on the force transmission component 1, with one end fixedly connected to the force transmission component 1, which can be done by welding. Furthermore, each set of fasteners 41 has a force-bearing portion 42, specifically a semi-circular protrusion on the surface of the stud. These semi-circular protrusions increase the interlocking force between the stud and surrounding materials such as concrete, resulting in a more secure fixation.

[0040] The working principle of the post-cast strip force transmission structure integrating high-performance alloy steel and composite materials in this application is as follows:

[0041] The post-cast strip force transmission structure uses I-beam high-performance alloy steel (such as HSLA steel) as the core of the force transmission component 1, utilizing its excellent mechanical properties to disperse and transmit force. Both ends of the force transmission component 1 are engaged with the L-shaped mounting plates of the end cap 3 via receiving grooves and reinforced with a first adhesive to enhance connection stability. Simultaneously, small conical protrusions (force-enhancing parts 12) on the surface of the force transmission component 1 increase friction with surrounding materials, improving force transmission stability. The force transmission component 1 is connected to the base plate or floor slab via welded studs (fixing parts 4). The semi-circular protrusions on the surface of the studs enhance the interlocking force with the concrete, making the force transmission component 1 and the base plate or floor slab form a unified load-bearing structure. The stress monitoring component 2 is adapted to the conical groove (receiving part) of the force transmission component 1 via a conical plastic insert rod (insertion part 21) and fixed with a second adhesive. Strain gauges are used to sense the deformation of the force transmission component 1 under stress, converting resistance changes into electrical signals to monitor the stress state, deformation, and crack development in real time.

[0042] This technology enables effective force transfer at the post-cast strip, forming an integral load-bearing structure and allowing real-time monitoring of the structural stress state. High-performance alloy steel and lightweight composite materials enhance durability and load-bearing capacity; stress monitoring improves structural safety and adaptability; and the overall design strengthens structural strength, stability, and resistance to deformation. It solves problems such as excessive localized stress at the post-cast strip, insufficient structural load-bearing capacity, high deformation risk, and difficulty in real-time monitoring of the stress state, thus reducing potential safety and quality hazards during construction.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
