[0002] With the improvement of people's living standards, higher requirements are put forward for housing construction. Land is a non-renewable resource. Building a conservation-oriented society does not allow unlimited stalls to occupy a large amount of arable land for construction. Old city renovation, maintenance and reinforcement of old buildings, and expanded application are one of the inevitable choices for urban construction. By reinforcing and renovating buildings to add floors, expand, and change their uses, old buildings can be revitalized. In the existing engineering renovation and reinforcement process, the original reinforced concrete structure is often treated with measures such as increasing the cross-section of reinforced beams or adding new beams, externally bonded steel plates for reinforcement, externally bonded steel sections and anchor bolts. In actual construction, a large number of reinforcement and renovation operations are carried out simultaneously, and some renovations also involve the demolition of the original main structure floor slabs, which leads to potential safety hazards in the building at any time, and the purpose of reinforcement and renovation cannot be truly achieved, resulting in great difficulty in reinforcement and renovation construction.

[0036] Embodiment 1

[0037] As Figure 1 and Figure 2 shown, a portable construction equipment for engineering renovation and reinforcement proposed by the present invention includes a floor slab 1. A first support beam 2 for supporting it is provided at the bottom of the floor slab 1. A second support beam 3 is provided between the first support beams 2, which can stably support the floor slab 1. A plurality of support assemblies 4 for reinforcing the second support beam 3 are arranged through the floor slab 1, and the support assemblies 4 are sleeved on the outer wall of the second support beam 3, which is convenient for providing stable support for the second support beam 3. A plurality of groups of limit assemblies 5 for positioning the support assemblies 4 are arranged through the second support beam 3, which can make the support assemblies 4 more stably connected to the second support beam 3.

[0038] As Figures 1 to 3 shown, the support assembly 4 includes stirrups 41, and the stirrups 41 are arranged in a "U" - shaped structure and can be sleeved on the outer wall of the second support beam 3. A plurality of steel bars 42 are arranged between the stirrups 41, and the stirrups 41 and the steel bars 42 are stably tied and connected by binding wires. A steel plate 43 is arranged through the upper end of the stirrups 41, and the steel plate 43 is located on the upper surface of the floor slab 1, which can stably limit the stirrups 41. A limit block 44 is fixedly arranged at the upper end of the stirrups 41, and the limit block 44 is located on the upper surface of the steel plate 43, which can stably limit the stirrups 41 and ensure the stability of the stirrups 41.

[0039] As Figures 1 to 4As shown, the limiting component 5 includes a clamping strip 51, which is a "U"-shaped structure, and the clamping strip 51 is sleeved with the stirrup 41, which can stably limit the stirrup 41, and one end of the clamping strip 51 is fixedly sleeved with a clamping block 52, which can stably fix the clamping strip 51 on the stirrup 41.

[0040] like Figure 1 and Figure 2 As shown, a plurality of first through holes 6 are provided on the floor slab 1 , and the first through holes 6 and the stirrups 41 are movably penetrated to facilitate the penetration of the stirrups 41 .

[0041] like Figure 3 As shown, a plurality of second through holes 7 are provided on the second support beam 3 , and the second through holes 7 and the clamping strips 51 are movably penetrated, so that the clamping strips 51 can penetrate and stably sleeved with the stirrups 41 .

[0042] Furthermore, a first clamping groove 8 is provided on the upper surface of the floor plate 1 , and the first clamping groove 8 is clamped with the steel plate 43 , so as to ensure that the floor plate 1 is flat.

[0043] Secondly, a plurality of second slots 9 are formed on the upper surface of the steel plate 43 , and the second slots 9 are engaged with the limit blocks 44 , so as to ensure the flatness of the upper surface of the steel plate 43 .

[0044] Furthermore, the adjacent sockets of the clamping strip 51 are arranged opposite to each other, which can increase the stability of the clamping strip 51 in fixing the stirrup 41 .

[0045] The working principle of this embodiment is: remove the deteriorated concrete on the outer surface of the floor slab 1 and the second support beam 3, and fully roughen the bonding surface, rinse the roughened bonding surface, and spray a layer of concrete interface binder. This step is to remove the bad parts of the structure surface so that the new and old concrete can be better combined, and at the same time, the bonding effect is enhanced by the interface binder, providing a good basic condition for subsequent reinforcement work.

[0046] Holes are drilled on the floor slab 1 and the second support beam 3 to form a first through hole 6 and a second through hole 7, and the holes are arranged equidistantly, and a first slot 8 is excavated on the upper surface of the floor slab 1. These holes and slots are arranged for the subsequent installation of the support assembly and the limit assembly. The equidistant arrangement can ensure uniform force and improve the stability of the overall structure. Subsequently, the stirrups 41 are placed equidistantly corresponding to the first through hole 6, and the steel bars 42 are placed between the stirrups 41 and stabilized by binding wire. In this way, the basic framework of the support assembly is constructed. The combination of steel bars and stirrups can provide good bending and shear resistance and enhance the bearing capacity of the structure. Afterwards, the stirrups 41 are passed through the first through hole 6 and the steel plate 43 from bottom to top, and the upper end of the stirrup 41 is clamped to the bottom surface of the limit block 44. During this process, the steel plate 43 is engaged with the first slot 8 on the floor plate 1, and the limit block 44 is engaged with the second slot 9 on the steel plate 43, ensuring the stability of the support assembly in the vertical direction and preventing it from vertical displacement, thereby providing effective vertical supporting force for the floor plate, enhancing the bearing capacity of the floor plate and preventing it from excessive deformation or damage due to force.

[0047] The openings of the clamping strips 51 are staggered and inserted between the stirrups 41, and penetrate through the second through hole 7, and then the clamping block 52 is clamped to one end of the clamping strips 51, so that the clamping strips 51 can stably limit the stirrups 41. Since the adjacent sockets of the clamping strips 51 are arranged oppositely, the clamping strips can limit the support assembly from different directions, effectively limiting the movement of the support assembly in the horizontal direction, ensuring that it always maintains a stable position when bearing a load, thereby ensuring the stability and reliability of the entire support structure.

[0048] A template is laid on the surface of the stirrup 41 to seal the stirrup 41 with the second support beam 3, and concrete is poured in the sealed template. The template is removed after solidification. Pouring concrete further enhances the connection strength and integrity between the support assembly and the second support beam 3, allowing the entire reinforcement structure to work better together, providing safe and efficient support guarantee for engineering renovation and reinforcement construction.
