Description

Technical Field

[0001] This utility model relates to the field of building reinforcement technology, specifically to an overall reinforcement mechanism for the structure of an expansion or renovation project. Background Technology

[0002] Foundation underpinning, also known as underground underpinning, in a narrow sense, refers to increasing the bearing capacity of existing building foundations by adding new permanent supports or foundations under the existing foundation. In a broader sense, it refers to the reinforcement and strengthening of existing foundations, improvement of the bearing stratum of the building's foundation, installation of new foundations, and replacement of old foundations when excavating earthwork directly under existing foundation buildings in order to eliminate the potential impact on the function and structure of existing foundation buildings.

[0003] After years of use, the structural stability and load-bearing capacity of the existing building's foundation and supporting columns will decrease. As a result, during renovation or expansion, the foundation and supporting columns are prone to collapse or breakage due to their unstable structure and limited load-bearing capacity.

[0004] Therefore, a solution is needed. Summary of the Invention

[0010] (III) Beneficial Effects This utility model provides a structural reinforcement mechanism for renovation and expansion projects. It has the following beneficial effects: This solution presents a structural reinforcement mechanism for renovation and expansion projects. By integrating the support base and support column into a single unit, it eliminates weak joints and optimizes stress distribution.

[0014] Please see Figure 1-4 This utility model provides a technical solution: Example 1 The problem to be solved is that after years of use, the structural stability and load-bearing capacity of the existing building's foundation and supporting columns will decrease. As a result, during renovation or expansion, the foundation and supporting columns are prone to collapse or breakage due to their unstable structure and limited load-bearing capacity.

[0015] The solution is as follows: A structural reinforcement mechanism for renovation and expansion projects includes a device body 1. The device body 1 includes a support base 2, a support column 3, and a base reinforcement device 4. The support base 2 and the support column 3 are smoothly transitioned and integrally formed. The support column 3 is located on top of the support base 2. The support base 2 has a trapezoidal shape, and the support column 3 has a rectangular shape. The base reinforcement device 4 includes a top mounting device 5, a bottom mounting device 6, and a reinforcing connecting arm 7. The top mounting device 5 is bolted to the right end of the support column 3, and the bottom mounting device 6 is mounted on the support base. 2. At the right end, the reinforcing connecting arm 7 is provided with several sets of reinforcing connecting arms, and several sets of reinforcing connecting arms are fixed between the mounting top plate device 5 and the mounting bottom plate device 6.

The top end of the structural arm 10 is mounted on the first mounting block 8 in an inclined manner. The bottom of the structural arm 10 is provided with a bending arm 11. The bending arm 11 has an L-shaped structure. The bottom of the bending arm 11 is fixed on the second mounting block 9. The surfaces of the first mounting block 8 and the second mounting block 9 are both provided with first fixing holes 14.

[0016] Analysis of the above: The installation of the top plate device 5 (connected to the support column 3) and the installation of the bottom plate device 6 (connected to the support seat 2) construct a triangular support mechanical system through multiple sets of reinforced connecting arms 7, which disperses the vertical load of the support column 3 laterally to the support seat 2, compensating for the insufficient lateral stiffness of the original structure; the bolts connect the installation of the top plate 5 to the support column 3, and the installation of the bottom plate 6 to the support seat 2; the screws fix the reinforced connecting arms 7 to the installation of the top plate 5 and the bottom plate 6; significantly improving the resistance to deformation; multiple sets of connecting arms can be arranged as needed, flexibly adapting to different building scales and renovation and expansion loads.

[0017] Example 2: Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the surface of the structural arm 10 and the bending arm 11 are provided with reinforcing holes 12, the reinforcing holes 12 are rhomboid in shape, and reinforcing blocks 13 are provided inside the reinforcing holes 12, the reinforcing blocks 13 are cross-shaped.

[0018] Analysis of the above content: The rhomboid reinforcing hole 12 naturally disperses stress by utilizing its geometric shape, and the cross reinforcing block 13 is embedded in the hole to further enhance the rigidity of the arm body, realizing "hole-block synergistic reinforcement"; it improves the structural arm body's own resistance to deformation, avoids the collapse of the reinforcement system due to arm body failure, and extends the service life of the mechanism.

[0019] Example 3: Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: the surface of the structural arm 10 is provided with a plurality of locking holes 15, and locking bolts 16 are inserted into the locking holes 15.

[0020] Analysis of the above content: The locking bolt 16 is inserted into the locking hole 15. By adjusting the preload, the tension of the connecting arm can be dynamically adjusted, or the surrounding structure can be fixed (to adapt to building deformation); it can dynamically adapt to complex working conditions (such as long-term settlement, new loads from renovation and expansion), prevent the connection from loosening, and ensure the long-term stability of the reinforcement effect.

[0021] Example 4: Please see Figure 1-4 This utility model provides a technical solution based on Embodiment 1: the mounting top plate device 5 and the mounting bottom plate device 6 are both rectangular in shape, and rubber bonding pads 17 are provided on the inner side of the mounting top plate device 5 and the mounting bottom plate device 6.

Then, the first mounting block 8 or the second mounting block 9 is embedded into the mounting groove 18 and fixed with screws.

[0023] Working principle: In the main body 1, the support base 2 (trapezoidal) and the support column 3 are integrally formed and smoothly transitioned. The trapezoidal shape expands the bottom support area to disperse the vertical load, while the rectangular shape efficiently transmits the force flow, laying a stable foundation. The mounting top plate device 5 (bolted to the support column 3) and the mounting bottom plate device 6 (connected to the support base 2) of the seat reinforcement device 4 form a triangular support system through multiple sets of reinforced connecting arms 7, dispersing the vertical load of the support column to the side of the support base. The reinforced connecting arms 7 rely on the first mounting block 8 and the second mounting block 9 (via the first fixing hole 1). 4. Fixed), so that the inclined structural arm 10 (decomposes vertical force) and the L-shaped bending arm 11 (optimizes stress path) form a composite force transmission path. Combined with the diamond-shaped reinforcing hole 12 with the embedded cross reinforcing block 13 to enhance the rigidity of the arm, and the locking hole 15 and locking bolt 16 to dynamically adjust the preload to adapt to complex working conditions; at the same time, the installation top plate device 5 and the installation bottom plate device 6 are equipped with inner rubber bonding pads 17 to buffer vibration and protect the original structure.
