Description

Technical Field

[0001] This utility model relates to a basic structure for old house renovation and the house itself, belonging to the field of construction engineering technology. Background Technology

[0002] When adding a new house to an existing roof (i.e., "roof addition" or "vertical addition"), the foundation structure is crucial. Since the existing floor slabs cannot withstand the load of the added floor, it is strictly forbidden to directly rely on the old roof slab for expansion. The load must be transferred to the load-bearing components through the foundation structure to ensure stable support for the new house. If the original foundation's bearing capacity is insufficient or excessive disturbance to the old structure needs to be avoided, pile foundations are an efficient and reliable solution. They reduce reliance on the existing foundation by transferring the load to deep, stable soil or rock layers. Because the added floor load acts on the pile foundation, traditional pile foundations are partially buried underground and partially extend upwards above ground. When the above-ground portion of the pile foundation is located inside the old house, it usually occupies the original area of ​​the old house and significantly alters its original layout. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a basic structure for old house renovation and a house for old house renovation. The basic structure for old house renovation can play a basic support role when a new house is built on the old house, while not causing significant changes to the original layout of the old house, and can also strengthen the walls of the old house.

[0004] To achieve the above objectives, the present invention provides a basic structure for the renovation of an old house, comprising multiple indoor pile support components. Each indoor pile support component includes an indoor underground pile buried underground and an indoor support steel member fixedly connected to the vertical top of the indoor underground pile. The indoor support steel member includes an angle steel set at the inner corner of the old house, and the two mutually perpendicular side plates of the angle steel are attached to the two vertical surfaces of the inner corner of the old house.

[0005] The indoor support steel components also include T-shaped steels installed on the interior walls of the old house. The web of the T-shaped steel is inserted into a vertical groove opened on the interior wall of the old house, and the flange of the T-shaped steel is attached to the interior wall of the old house.

[0006] The basic structure for the old building renovation also includes an outdoor support frame, which includes multiple outdoor pile support components. Each outdoor pile support component includes an outdoor underground pile buried underground and an outdoor support steel member fixedly connected to the vertical top of the outdoor underground pile.

[0007] The outdoor support frame also includes a first transverse support steel member, the top of which is connected to the top of the indoor support steel member via the first transverse support steel member.

[0008] The outdoor support frame also includes a second transverse support steel member, which is connected between the top ends of two adjacent outdoor support steel members.

[0009] The indoor and outdoor underground piles are cast-in-place piles, static pressure piles, or screw-in piles.

[0010] This utility model also provides a house renovation project, including the old house renovation foundation structure as described above, a floor slab built on the old house renovation foundation structure, and an upper-level new house built on the floor slab.

[0011] By adopting the above technical solution, the basic structure for old house renovation and the renovated house of this utility model have the following advantages compared with the prior art:

[0012] 1. The technical solution of this utility model can minimize interference with the original layout of the old house. The interior supporting steel components adopt the method of angle steel fitting the inner corner and T-shaped steel embedded in the wall groove, making full use of the existing structural space, avoiding the occupation of indoor area, preserving the original room layout and function to the greatest extent, and reducing damage to the interior decoration and structure of the old house through local reinforcement rather than overall renovation.

[0013] 2. By using indoor and outdoor underground piles, the load of the additional floor is directly transferred to the deep stable soil layer, avoiding the problem of insufficient bearing capacity of the old floor slab and ensuring the safety of the old and new structures. The outdoor support frame is rigidly connected to the indoor support components through the first lateral support steel member, forming a spatial force system, dispersing the load and enhancing the overall resistance to lateral displacement.

[0014] 3. It can provide additional reinforcement to the structure of old buildings; T-shaped steel is embedded in the wall groove and angle steel wraps the inner corners, forming targeted reinforcement of key stress nodes, significantly improving the shear and bending resistance of the old building walls, and improving the seismic resistance and durability of the original structure.

[0015] 4. Reduce earthwork excavation, reuse existing structures, facilitate construction, and avoid comprehensive reinforcement of old building foundations by optimizing force transmission paths, thereby reducing renovation costs.

[0016] 5. Adaptable to different building forms, the combination of angle steel and T-shaped steel can match diverse old building floor plans (such as L-shaped and T-shaped walls).

[0017] In summary, through the innovative combination of "pile foundation force transmission + embedded reinforcement + spatial collaborative support" of this utility model, multiple goals such as layout preservation, structural reinforcement, convenient construction, and economic efficiency are achieved in the renovation of old houses while ensuring the safety of the added floors. It is especially suitable for residential or historical building renovation scenarios that require strict protection of the original functions. Attached Figure Description
