Description

Technical Field

[0001] This application belongs to the field of building construction technology, specifically a seismic-resistant RC frame structure column. Background Technology

[0002] RC frame structure columns are the core components of a frame structure, bearing the crucial task of effectively transferring the loads from the beams and slabs to the foundation, thereby ensuring the stability of the building. In seismic design, RC frame structures typically employ a strong column-weak beam yielding mechanism, meaning the yield strength of the columns is higher than that of the beams, to protect the beams from yielding before the columns during an earthquake, thus reducing structural damage. For example, application CN204781601U discloses a seismic-resistant RC frame structure column, including a body with a cross-section of 800mm×800mm. The body includes a reinforcing cage and concrete poured on the reinforcing cage. The reinforcing cage has several longitudinal bars made of hot-rolled ribbed steel bars and several stirrups made of hot-rolled plain round steel bars arranged on the longitudinal bars. The stirrups are arranged at equal intervals along the longitudinal direction. Several reinforcing steel sections are set vertically at the construction joint of the body to improve the axial bearing capacity at the construction joint of the RC frame structure column, or several tenons are set on the pre-cast block at the construction joint of the body. This utility model has a good seismic resistance effect, reduces the impact of construction joints on the seismic resistance of the RC frame structure column, ensures the quality of construction joint construction in engineering construction, and improves the seismic performance of the entire frame structure.

[0003] However, the cast-in-place reinforced concrete frame structure in this application also has its drawbacks. For example, due to the large number of formwork joints in the column root joint area, the splicing is prone to looseness, which may lead to grout leakage and poor casting quality. The quality of the casting directly affects the overall seismic performance. Moreover, when the frame is welded to the ground, the large welding area can easily generate large residual stress, which affects the stress performance of the joint. Utility Model Content

[0004] The purpose of this application is to provide a seismic-resistant RC frame structure column in order to solve the problems of grout leakage and residual stress generated by welding mentioned above.

[0005] The technical solution adopted in this application is as follows: A seismic-resistant RC frame structure column includes a node column. A plywood is provided on the lower outer surface of the node column, and an angle steel is installed on the lower outer surface of the plywood. A limit hole is opened on the outer surface of the node column, a limit nail is connected to the outer surface of the angle steel, a limit nut is provided on the inner surface of the limit nail, a locking screw is connected to the outer surface of the angle steel, a locking nut is installed on the outer surface of the locking screw, a ground anchor is installed on the lower upper surface of the angle steel, a fixing nut is provided on the upper surface of the ground anchor, and a concrete ground is fixedly connected to the lower surface of the ground anchor.

[0006] By adopting the above technical solution, the installation of plywood prevents mortar leakage and seepage inside the joint column, thus preventing root rot during pouring. Installing angle steel on the outside of the plywood further secures it, ensuring a more stable installation of the plywood inside. The installation of limiting holes and nails further tightens and stabilizes the connection between the joint column, plywood, and angle steel. Angle steel is a common material in the construction industry, with low production costs. This structure also allows for easier disassembly and installation by workers, and its high reusability provides protection. For convenience, installing locking screws ensures a more stable and tight connection between the four angle steels below the node column, preventing gaps or loosening during installation. Installing locking nuts on the outer surface of the locking screws allows workers to easily tighten or loosen the angle steels, and also makes disassembling them faster and more convenient. Installing ground anchors and embedding them into the concrete floor makes the upper device more stable, and installing fixing nuts makes the ground anchors on the inner surface more stable, preventing the upper device from loosening due to unstable ground anchors, thus making it convenient and practical.

[0007] In a preferred embodiment, a crossbeam is fixedly connected to the upper surface of the node column.

[0008] By adopting the above technical solution, a frame can be formed by connecting the crossbeam to the upper surface of the node column, which increases the overall rigidity and stability. It can also share part of the weight of the node column, prevent deformation of the node column due to long-term use, and make it stable and protective.

[0009] In a preferred embodiment, a support plate is mounted on the lower surface of the crossbeam, a connecting rod is mounted on the lower surface of the support plate, and a support plate is provided on the lower surface of the connecting rod.

[0010] By adopting the above technical solution, the installation of the support plate can distribute the weight of the upper crossbeam, avoiding the deformation of the overall frame caused by the excessive weight of the crossbeam. The installation of the support plate and connecting rod can make the upper force more even and reliable, and it is more convenient to disassemble and install, making it convenient and practical.

[0011] In a preferred embodiment, a support rod is connected to the lower surface of the support plate, a threaded rod is provided on the lower inner surface of the support rod, and a universal support foot is provided on the lower surface of the threaded rod.

[0012] By adopting the above technical solution, the support plate above can be made more stable by installing support rods, and the deformation and bending of the support plate caused by long-term use can be avoided. Installing threaded rods and universal support feet can distribute the force at the joint between the support plate and the node column to the surface of the concrete ground, reducing the pressure on the support plate and node column, and making it fixed and protective.

[0013] In a preferred embodiment, an energy-absorbing layer is provided on the outer surface of the node column, and anti-collision corner guards are installed on the outer surface of the energy-absorbing layer.

[0014] By adopting the above technical solution and installing anti-collision corner guards to cover the surface of the node column, it is possible to prevent workers from being injured or endangered by impacts to the node column during construction, thus protecting the health of construction workers. The installation of an energy-absorbing layer can improve the buffering effect, allowing the anti-collision corner guards on the outer surface to recover more quickly when impacted, thus providing protection and safety.

[0015] In a preferred embodiment, an anti-collision layer is fixedly installed on the outer surface of the anti-collision corner guard.

[0016] By adopting the above technical solution, the sharp corners of the node column can be better covered by the installation of the anti-collision layer, preventing injury caused by accidental contact, thus making it both protective and practical.

[0017] In a preferred embodiment, a magnesium alloy core is installed on the inner surface of the node post, a soft steel core is installed on the inner surface of the magnesium alloy core, and mortar is provided on the inner surface of the soft steel core.

[0018] By adopting the above technical solution, the stability of the overall device can be enhanced by installing magnesium alloy core material and soft steel core material, forming an internal spatial frame, which can improve the rigidity and seismic performance of the wall, effectively preventing collapse caused by earthquakes. Installing mortar can make it form a more stable frame, giving it stability and safety.

[0019] In a preferred embodiment, the outer surface of the node post is provided with bolt holes, and bolts are provided on the outer surface of the bolt holes.

[0020] By adopting the above technical solution, the internal node columns, magnesium alloy core material and soft steel core material can be installed more stably by installing bolt holes and threaded rods, avoiding loosening that would lead to a decrease in overall seismic performance, and making it adaptable and stable.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: In this application, installing plywood prevents mortar leakage and seepage inside the joint column, thus preventing root rot during pouring. Installing angle steel on the outside of the plywood further secures it, ensuring a more stable installation of the plywood inside. Installing limiting holes and pins further tightens the connection between the joint column, plywood, and angle steel, making installation more secure and reliable. Angle steel is a common material in the construction industry, with low production costs. This structure also allows for easier disassembly and installation by workers, and its high reusability provides both protection and convenience. The installation of locking bolts ensures a more stable and tight connection between the four angle steels below the node column, preventing gaps or loosening during installation. Installing locking nuts on the outer surface of the locking bolts allows workers to easily tighten or loosen the angle steels, and also makes disassembly faster and more convenient. Installing ground anchors and embedding them into the concrete floor further stabilizes the upper structure. Installing fixing nuts further secures the ground anchors on the inner surface, preventing loosening of the upper structure due to unstable anchors, thus enhancing convenience and practicality.

Installing the plywood 10 prevents leakage and seepage of the poured mortar inside the node column 1, preventing root rot during pouring. Installing the angle steel 5 on the outside of the plywood 10 further tightens the angle steel 5, making the plywood 10 more securely installed inside the angle steel 5. The limiting hole 9 and the limiting nail 13 ensure a tighter and more stable connection between the node column 1, the plywood 10, and the angle steel 5. Furthermore, the angle steel 5 is a common material in the construction industry with low production costs. This structure allows for easier disassembly and installation by workers, and its high reusability provides both protection and convenience.

[0035] The implementation principle of this application's seismic-resistant RC frame structure column embodiment is as follows: Installing plywood 10 prevents leakage and seepage of the poured mortar inside the node column 1, thus preventing root rot during pouring. Installing angle steel 5 on the outside of the plywood 10 further secures it, ensuring a more stable installation of the plywood 10 inside the angle steel 5. Installing limiting holes 9 and limiting nails 13 ensures a tighter and more stable connection between the node column 1, plywood 10, and angle steel 5. Furthermore, angle steel 5 is a common material in the construction industry with low production costs.
