Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a transition connection structure between the indoor floor and the wall of a building to prevent settlement. Background Technology

[0002] In the field of building construction, the transition joint between the interior floor and the wall is a sensitive area for structural stress and deformation, and its stability directly affects the overall performance and service life of the building. As the building's service life increases and the foundation environment changes, such as fluctuations in groundwater level, soil consolidation, and long-term load effects, the transition joint is prone to quality problems due to settlement differences.

[0003] The existing transition between the ground and the wall often adopts a simple form where the wall rests directly on the foundation, without the setting of a dedicated load-distribution component. The self-weight of the wall and the load of the superstructure are directly transferred to a local area of ​​the foundation through the bottom of the wall, while the load of the ground base is borne only by the foundation below the ground, forming a single-point concentrated force mode. This single load transfer path causes the corresponding area of ​​the foundation to be subjected to pressure far exceeding the design threshold for a long time. Especially in the case of soft soil foundation or uneven foundation compaction, it is easy to cause local compression deformation of the foundation, which in turn causes settlement problems between the wall and the ground.

[0004] To address this issue, the present invention provides a transitional connection structure between the interior floor and walls of a building to prevent settlement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a transitional connection structure between the interior floor and walls of a building to prevent settlement, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transitional connection structure between an indoor floor and a wall for preventing settlement, comprising a foundation, an anti-settlement mechanism provided on the upper surface of the foundation, a second steel reinforcement frame fixedly connected to the inner side of the anti-settlement mechanism, a plurality of first steel reinforcement frames provided inside the second steel reinforcement frame, the anti-settlement mechanism comprising an installation groove and a plurality of limiting grooves provided on the upper surface of the foundation, a support plate attached to the upper surface of the limiting groove, an installation shell provided on the inner side of the installation groove, and a wall fixedly connected to the upper surface of the installation shell.

[0007] Furthermore, the side surface of the mounting housing is provided with an inwardly recessed support groove, and the inner wall of the support groove is fixedly connected with multiple sets of fixing bolts. The side surface of the support plate is provided with a mounting hole, and one end of the fixing bolt passes through the inner wall of the mounting hole.

[0008] By adopting the above technical solution, a rigid connection between the mounting shell and the support plate is achieved by passing fixing bolts through the mounting holes of the support plate. The load transferred from the wall to the mounting shell is distributed to the support plate, and then transferred to the foundation through the support plate.

[0009] Furthermore, a nut is threaded onto the outer surface of the fixing bolt, and the outer surface of the nut is in contact with the side surface of the support plate.

[0010] By adopting the above technical solution, the installation shell and the support plate can be detachably fastened by the threaded connection of the nut and the fixing bolt, which facilitates the adjustment of the component position during construction and also makes it convenient to disassemble and repair during later maintenance.

[0011] Furthermore, a concrete pouring layer is poured on the upper surface of the foundation, the outer surface of the concrete pouring layer fills the interior of the limiting groove, and an expansion bolt is threadedly connected to the upper surface of the support plate, the lower end of the expansion bolt being threadedly connected to the upper surface of the limiting groove.

[0012] By using the above technical solution, the limiting groove is filled with concrete pouring layer and covered with the upper surface of the foundation, which can tightly wrap the support plate, the bottom of the mounting shell and the foundation. The expansion bolts connect the support plate and the limiting groove, which further strengthens the fixing effect between the support plate and the foundation, prevents the support plate from sliding horizontally or tilting vertically under load, and improves the structural stability against settlement.

[0013] Furthermore, the interior of the concrete pouring layer is provided with vertical and horizontal reinforcing bars, and the outer surfaces of the vertical and horizontal reinforcing bars are bound together with steel wire.

[0014] By adopting the above technical solution, a grid-like steel reinforcement skeleton is formed by binding the vertical and horizontal steel bars with steel wires. This can significantly improve the tensile and shear strength of the concrete pouring layer, solve the defect of weak tensile properties of concrete, prevent tensile cracks in the concrete pouring layer due to foundation settlement, and the grid-like steel reinforcement skeleton can evenly transfer the load borne by the concrete pouring layer to the foundation, avoiding local load concentration that could lead to cracking or spalling of the pouring layer.

[0015] Furthermore, the mounting shell and the support plate are made of duplex steel, and the first and second steel reinforcement frames are located inside the wall.

[0016] By adopting the above technical solution, the duplex steel, which has both austenitic and ferritic structures, has extremely strong corrosion resistance and can resist the erosion of corrosive media such as acid and alkali substances in the foundation soil and chloride ions in groundwater. This avoids the structural strength of the installation shell and support plate from decreasing due to rust, thus extending the service life.

[0019] 1.

The support plates are fixed to the foundation with expansion bolts and limiting grooves, which can stably transfer the distributed load to the foundation, reduce the impact of the load on the foundation, prevent the foundation from sinking due to excessive local stress, greatly improve the structural anti-settlement stability, and effectively prevent the problem of cracks in the transition area between the floor and the wall due to settlement.

[0020] 2. The transition connection structure between the indoor floor and the wall of this anti-settlement building uses a duplex steel installation shell and support plate, which is corrosion-resistant and has good toughness, avoiding damage caused by rust and settlement stress. The first and second steel reinforcement skeletons enhance the foundation strength, and the grid-like steel reinforcement skeleton improves the tensile and shear resistance of the concrete pouring layer, preventing cracks and spalling.

The outer surface of the nut 407 is attached to the side surface of the support plate 406.

[0030] Furthermore, a concrete pouring layer 3 is poured on the upper surface of the foundation 1. The outer surface of the concrete pouring layer 3 fills the interior of the limiting groove 404. An expansion bolt 403 is threadedly connected to the upper surface of the support plate 406. The lower end of the expansion bolt 403 is threadedly connected to the upper surface of the limiting groove 404.

[0031] In this embodiment, the rigid connection between the fixing bolt 402 and the support plate 406 can efficiently distribute the load from the wall 2 to the mounting shell 401 to the support plate 406, avoiding overload on a single point of the mounting shell 401 and preventing the wall 2 from tilting due to concentrated load deformation.

The support plate 406 is fixed to the limiting groove 404 of the foundation 1 via expansion bolts 403, transferring the load to the foundation 1. At the same time, the grid-like steel reinforcement skeleton in the concrete pouring layer 3 evenly transfers the surface load to the foundation 1, preventing excessive stress in a single area from causing settlement. The mounting groove 405 and limiting groove 404 on the foundation 1... 4 provides positioning for the installation of the outer shell 401 and the support plate 406, ensuring the initial installation position of the components is stable.
