Description

Technical Field

[0001] This invention belongs to the field of reinforcement construction technology, specifically relating to an in-situ replacement construction device for frame beams and columns in a brick-concrete structural system. Background Technology

[0002] With the national call for energy conservation and emission reduction, the direction of modern infrastructure construction has also shifted, and many existing buildings have begun to be renovated and repaired. Among these, building demolition and reinforcement construction projects, as preliminary components of the overall renovation project, are of particular importance in terms of construction techniques and quality.

[0003] Traditional underpinning construction requires temporary supports to replace the original structure's load-bearing capacity. However, conventional supports are prone to structural safety hazards due to uneven stress or poor stability, especially in brittle material systems like brick-concrete structures. Traditional processes rely on manual positioning, formwork, and drilling, requiring multiple adjustments to equipment positions. Furthermore, on-site assembly of formwork is necessary when pouring the support structure, which is time-consuming and labor-intensive. In traditional renovations, stress concentration or poor bonding at the interface between the newly added components and the original structure can easily occur, resulting in insufficient overall stiffness after underpinning and limited improvement in seismic performance. The lack of specialized equipment and reliance on manual material handling and support structure adjustments leads to high labor intensity and difficulty in ensuring accuracy, especially in indoor construction of brick-concrete structures with limited space. To address these issues, we propose an in-situ underpinning construction device for frame beams and columns in brick-concrete structural systems. Summary of the Invention

[0004] The purpose of this invention is to provide a construction device for in-situ replacement of frame beams and columns in a brick-concrete structural system. This device features modular assembly and standardized construction, simultaneous construction of temporary support and permanent structure, and in-situ replacement to avoid the risk of structural demolition. It eliminates the need to dismantle the original brick-concrete structure, and forms a combined structure with the original components by adding steel bars, concrete, and steel profiles. This gradually transfers the stress path and avoids the structural instability risk caused by traditional demolition processes. It is particularly suitable for the reinforcement of old buildings, optimizing the stress system and significantly enhancing the load-bearing capacity.

[0005] The specific technical solution adopted by this invention is as follows:

[0006] A construction device for in-situ replacement of frame beams and columns in a brick-concrete structural system includes a frame column installation mechanism and a frame beam installation mechanism.

[0011] In a preferred embodiment, the frame beam casting support body includes a horizontally arranged first casting support plate and a second casting support plate, with a vertically arranged third casting support plate between the first and second casting support plates. The third casting support plate is movably connected to both the first and second casting support plates.

[0012] In a preferred embodiment, the second drive body includes a mounting base, on which a third driver is mounted. The output end of the third driver is connected to a lead screw, and the end of the lead screw away from the third driver is rotatably connected to a fixed base. The ends of the two first rotating parts away from the first support plate are each rotatably connected to second sliding blocks. The mounting base is provided with sliding rails that match the second sliding blocks. A nut that matches the lead screw is provided between the two second sliding blocks, and the nut is connected to the second sliding blocks through a first connecting rod.

[0013] In a preferred embodiment, the movable drilling body includes a horizontally arranged first movable plate, which is hollow. Two symmetrically arranged second movable plates are slidably connected inside the first movable plate, and the opposite ends of the two second movable plates pass through the two side walls of the first movable plate.

A fourth driver is provided on the inner wall of the first movable plate, and the output end of the fourth driver is connected to a second gear.

[0016] The technical effects achieved by this invention are as follows:

[0017] When in-situ replacement of frame beams and columns in a brick-concrete structure is required, the first driver is activated to move the second roller, moving the independent frame column pouring vehicle to the construction position. The second driver is activated to rotate the rotating rod and the first gear, causing the second support rod to move vertically, so that the top load-bearing plate presses against the top wall of the frame column construction area, serving as a temporary alternative support. The pouring slab is then placed in the corresponding positions of the third and fifth support rods. After the pouring slab is constructed, steel bars are inserted, cement is injected, and steel sections are added. After the cement solidifies, the fourth support rod is removed, and the pouring slab is taken out. By adding steel bars, concrete, steel sections, and other materials, a combined structure is formed with the original components, transferring the force transmission path of the original structure to the new "frame beam and column" system, giving it stronger bending, shear, and seismic resistance.

[0018] When frame beam construction is required, the frame beam installation mechanism is moved to the ring beam construction position. The third drive is activated to rotate the lead screw, which in turn moves the nut, causing the second sliding block and the first rotating component to move. The first support plate is pushed to the same working height as the ring beam. The fourth drive is activated to rotate the second gear, causing the two second moving plates to move in opposite directions. This, in turn, causes the installation rod and drilling rig to move horizontally. The drilling rig is moved to a suitable drilling position, and after drilling, the reinforcing steel bars are inserted. The fixing plate is installed on the wall with installation screws. The first and second cast-in-place support plates are aligned with the reinforcing steel bars, and concrete is injected through the pouring port to form a composite frame beam with the original ring beam. The I-beams and steel plates are poured into the newly added concrete. The synergistic effect of the steel and concrete enhances the bending stiffness of the beam, and the newly added reinforcing steel bars are connected continuously. Attached Figure Description

[0041] In this invention, when in-situ replacement of frame beams and columns in a brick-concrete structure system is required, and frame column construction is carried out, the first driver 20 is opened to drive the second roller 21 to move, moving the independent frame column pouring vehicle to the construction position. The second driver 25 is opened to drive the rotating rod 26 and the first gear 27 to rotate, driving the second support rod 23 to move in the vertical direction, so that the top load-bearing plate 24 abuts against the top wall of the frame column construction area, playing the role of temporary replacement support.

The fourth driver 44 is turned on to rotate the second gear 45, which in turn moves the two second moving plates 41 in opposite directions, thereby moving the installation rod 42 and the drilling machine 43 in the horizontal direction. The drilling machine 43 is moved to a suitable drilling position. After drilling with the drilling machine 43, the reinforcing steel is inserted. The fixing plate 46 is installed on the wall with the installation screws 47. The first cast support plate 28 and the second cast support plate 29 are aligned with the reinforcing steel. Concrete is injected through the pouring port 31 to form a combined frame beam with the original ring beam. The I-beams and steel plates are poured into the newly added concrete. The synergistic effect of the steel and concrete improves the bending stiffness of the beam. The newly added reinforcing steel is connected through the wall.
