Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a prefabricated building support for building engineering. Background Technology

[0002] Prefabricated construction is a modern industrialized construction method that transfers much of the on-site work from traditional construction to factories, enabling the prefabrication of building components and accessories, which are then assembled and installed on the construction site. In prefabricated construction, columns, as part of the load-bearing structure, are crucial for their stability and support. Prefabricated support bases can effectively improve the installation efficiency and structural safety of columns.

[0003] Traditional prefabricated building support structures struggle to quickly level the base plate when the construction site is uneven, leading to significant vertical deviations after component installation and affecting the accuracy of the building structure. Furthermore, most support structures use a single threaded adjustment or stacked fixed blocks, which cannot adapt to the installation requirements of components with different floor heights. The adjustment process is cumbersome, requiring frequent disassembly and reassembly, severely impacting construction efficiency. Additionally, the connection between the adjustment mechanism and the base plate in traditional support structures is often rigid. When the support studs tilt slightly, the base plate needs to remain level, causing accelerated thread wear and even jamming, further reducing the reliability of the support structure. Utility Model Content

[0004] To address the aforementioned shortcomings, this utility model provides a prefabricated building support for construction engineering, solving the problems of difficulty in adjusting the level and height and poor structural stability of existing support systems.

[0005] To achieve the above objectives, the technical solution provided by this utility model is a prefabricated building support base for construction engineering, including a base plate, adjustable support feet provided at the four corners of the base plate, a connecting seat fixedly connected to the top center of the base plate, an installation hole fixedly connected to the surface of the connecting seat, and a limit frame fixedly connected to the top center of the connecting seat.

[0006] The adjustable support foot includes a rotating seat, the rotating seat has a cavity at its center, the cavity has a threaded cylinder, the surface of the threaded cylinder is symmetrically fixedly connected to a connecting shaft, the connecting shaft is rotatably connected to the rotating seat, the center of the threaded cylinder is threadedly connected to a threaded column, the bottom end of the threaded column is rotatably connected to a conical block, the top of the conical block is fixedly connected to a pressure plate, and the rotating seat is rotatably connected to a base plate.

[0007] Preferably, a hexagonal column is fixedly connected to the top of the threaded column, the top of the rotating seat extends to the top of the base plate and is fixedly connected to a hexagonal block, and the inner wall of the cavity is provided with a rotating hole adapted to the connecting shaft.

[0008] Preferably, the inner diameter of the cavity is larger than the outer diameter of the threaded cylinder, and a lock nut is threadedly connected to the surface of the threaded column above the threaded cylinder.

[0009] Preferably, a height adjustment seat is fixedly connected to the top of the connecting seat, and the height adjustment seat and the connecting seat are fixedly connected by bolts.

[0010] Preferably, the height adjustment seat includes a base frame and a lifting frame. The base frame is fixed to the top of the connecting seat. The surface of the lifting frame is vertically slidably connected to the inner wall of the base frame. The surface of the base frame is provided with first fixing holes at equal intervals. The surface of the lifting frame is provided with second fixing holes at equal intervals. The lifting frame and the base frame are fixedly connected by fixing bolts. The top of the lifting frame is fixedly connected to a lifting connecting seat.

[0011] Preferably, the surface of the lifting connecting seat is fixedly connected with a second mounting hole, and the top center of the lifting connecting seat is fixedly connected with a second limiting frame.

[0012] The present invention adopts the above-mentioned technical solution, and its beneficial effects include: The prefabricated building support base in this type of construction project features an adjustable support foot and a rotating connection to the base plate, with the threaded cylinder and rotating seat rotating to avoid a rigid connection between the threaded cylinder and the base plate. During adjustment, the threaded cylinder and the base plate do not interfere with each other. When the base plate tilts due to uneven ground, the threaded cylinder can rotate and tilt around the connecting shaft, avoiding hard friction between the thread and the threaded cylinder that would lead to increased wear, and ensuring smooth rotation of the threaded cylinder. Since the adjustable support foot allows the threaded cylinder to tilt within a certain range, rotating the hexagonal block drives the threaded cylinder to rotate, simultaneously adjusting the height of the threaded cylinder, ensuring the base plate remains level even on uneven ground, solving the problem of adjustment failure caused by the vertical fixation of traditional support feet. Through the height adjustment seat, a wide range of height adjustment can be achieved, adapting to different component installation heights without disassembly, thus improving construction efficiency.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Example 1: Please refer to Figure 1 , Figure 3 This utility model provides a technical solution: a prefabricated building support base for construction engineering, including a base plate 1, adjustable support feet 2 at the four corners of the base plate 1, a connecting seat 3 fixedly connected to the top center of the base plate 1, mounting holes 4 fixedly connected to the surface of the connecting seat 3, and a limiting frame 5 fixedly connected to the top center of the connecting seat 3. In use, the column can be directly and vertically fixed to the top of the connecting seat 3, and the outer surface of the limiting frame 5 contacts the inner wall of the column to prevent the column from sliding laterally. The column can be fixed by bolts through the mounting holes 4.

[0021] The adjustable support foot 2 includes a rotating seat 201, with a cavity 202 at its center. A threaded cylinder 203 is housed within the cavity 202. Connecting shafts 204 are symmetrically fixed to the surface of the threaded cylinder 203, and are rotatably connected to the rotating seat 201. A threaded post 205 is threadedly connected to the center of the threaded cylinder 203. A conical block 206 is rotatably connected to the bottom end of the threaded post 205. A pressure plate 207 is fixedly connected to the top of the conical block 206. 7. The increased contact area with the ground improves the overall stability. The rotating seat 201 is rotatably connected to the base plate 1. A hexagonal column 208 is fixedly connected to the top of the threaded column 205. The hexagonal column 208 facilitates the rotation of the threaded column 205. The top of the rotating seat 201 extends to the top of the base plate 1 and is fixedly connected to a hexagonal block 209. The hexagonal block 209 facilitates the operation of the rotating seat 201 and the adjustment of the orientation of the connecting shaft 204. The inner wall of the cavity 202 is provided with a rotating hole that matches the connecting shaft 204.

[0022] The inner diameter of the cavity 202 is larger than the outer diameter of the threaded cylinder 203, which ensures that the threaded cylinder 203 can rotate inside the cavity 202 to accommodate the tilt of the threaded column 205. A locking nut 2010 is threadedly connected to the surface of the threaded column 205 and above the threaded cylinder 203.

[0023] When the ground at the steel structure column installation site is uneven, the support base is placed on the ground, and the conical block 206 is inserted into the ground to prevent lateral sliding, so that the bottom of the bearing plate 207 contacts the ground. Use a hex wrench to rotate the hexagonal block 209 at the top of the rotating base 201. Since the threaded cylinder rotates with the rotating base 201 through the connecting shaft 204, and the rotating base 201 is rotatably connected to the base plate 1, the threaded column 205 can automatically adjust its posture according to the tilt angle of the base plate to maintain the coaxiality of the threaded fit. Rotating the threaded column 205 simultaneously adjusts the height of the four corner support feet. The level of the base plate 1 is monitored by a level instrument until the base plate 1 is level. Tighten the locking nut 2010 to fix the threaded column 205 in the current position to prevent loosening during construction.

[0024] Example 2: Please refer to Figure 2 , Figure 4 and Figure 5 A height adjustment seat 6 is fixedly connected to the top of the connecting seat 3, and the height adjustment seat 6 is fixedly connected to the connecting seat 3 by bolts 7.

[0025] The height adjustment seat 6 includes a base frame 601 and a lifting frame 602. The base frame 601 is fixed to the top of the connecting seat 3. The surface of the lifting frame 602 is vertically slidably connected to the inner wall of the base frame 601. The surface of the base frame 601 is provided with first fixing holes 603 at equal intervals, and the surface of the lifting frame 602 is provided with second fixing holes 604 at equal intervals. The lifting frame 602 and the base frame 601 are fixedly connected by fixing bolts 605. The fixing bolts 605 are connected to the fixing holes at different positions to change the distance between the top of the lifting frame 602 and the base frame 601, thereby realizing height adjustment. The top of the lifting frame 602 is fixedly connected to a lifting connecting seat 606. The surface of the lifting connecting seat 606 is fixedly connected with a second mounting hole 607. The top center of the lifting connecting seat 606 is fixedly connected to a second limiting frame 608. The lifting connecting seat 606 can be connected to the column.
