Description

Technical Field

[0001] The present application relates to the technical field of support bases, and in particular to a detachable movable base. Background Art

[0002] Prefabricated houses, as environmentally friendly and economical buildings, feature a color-coated steel frame and sandwich panel enclosure. Through a standard modular system, they allow for flexible spatial configuration and utilize bolted connections. These structures not only demonstrate efficient and rapid construction, but also fully embody environmentally friendly and energy-saving design concepts. This architectural form has enabled universal standardization in the temporary construction sector, significantly improving both efficiency and quality.

[0003] Prefabricated homes are typically secured to the steel pipes of the external scaffolding. The following method is typically used to secure the lower end of the steel pipe to the ground: first, firmly drive expansion screws into the concrete floor to provide a stable support base for the steel pipe; then, precisely position the lower end of the steel pipe to one side of the expansion screws, forming a stable support structure with the ground; and finally, weld the lower end of the steel pipe to the expansion screws.

[0004] Traditional fixing methods face significant challenges when securing prefabricated houses, particularly in windy and sandy regions like the northwest. While expansion screws effectively anchor the steel pipes into the ground, the simple welding connection between the lower end of the steel pipe and the expansion screws is significantly insufficient in terms of tensile strength. Long-term high winds can exert continuous pressure on prefabricated houses, often causing welds to break, leading to failure in the fixing of the lower end of the steel pipes and seriously threatening the structural stability of the entire prefabricated house. Utility Model Content

[0005] The purpose of this application is to provide a detachable movable base to solve the problem of poor connection strength between the lower end of the steel pipe and the ground in the above-mentioned related art.

[0006] The present application provides a detachable movable base adopting the following technical solution:

[0007] A detachable movable base includes a steel pipe base and a flange base installed on one side of the steel pipe base. A fixing cavity for inserting and fixing the steel pipe is opened on the side of the steel pipe base away from the flange base, and a plurality of mounting through holes are opened on the flange base.

[0008] By adopting the above technical solution, due to the coordinated arrangement of the steel pipe seat and the flange base, during the installation process of the lower end of the steel pipe and the ground, the flange base can be fixed to the ground in advance by passing the expansion screw through the installation hole, and then the lower end of the steel pipe can be placed and fixed in the fixing cavity. This not only facilitates the subsequent disassembly and fixation of the steel pipe, but also strengthens the connection strength between the lower end of the steel pipe and the ground, reducing the impact of severe weather such as strong winds on the fixed steel pipe.

[0009] Optionally, the steel pipe seat and the flange base are fixed by welding.

[0010] By adopting the above technical solution, since the steel pipe seat and the flange base are fixed by welding, the possibility of loose installation between the steel pipe seat and the flange base is reduced.

[0011] Optionally, an upper triangular seat is fixed on the side of the flange base facing the steel pipe seat, and a lower triangular seat is fixed on the side of the steel pipe seat facing the flange base; the upper triangular seat and the lower triangular seat are rotatably connected via a hinge shaft, and the flange base is provided with an adjustment member for limiting the rotation angle of the steel pipe seat.

[0012] By adopting the above technical solution, when the movable base is used on a sloped concrete ground, due to the coordinated arrangement of the upper triangular seat, the lower triangular seat and the adjusting member, the angle between the flange base and the steel pipe seat can be adjusted according to actual conditions, and then the two can be limited and locked by the adjusting member after adjustment, thereby improving the applicability of the movable base.

[0013] Optionally, two waist-shaped adjustment holes are provided on the upper triangular seat, and the two waist-shaped adjustment holes are symmetrically arranged on both sides of the hinge shaft, and the adjustment member includes two adjustment bolts passing through the waist-shaped adjustment holes.

[0014] By adopting the above technical solution, when the upper triangular seat and the lower triangular seat that have been rotated and adjusted are limited and locked, the two adjusting bolts are passed through the corresponding two waist-shaped adjustment holes, and the adjusting bolts are slid in the waist-shaped adjustment holes so that the outer periphery of the adjusting bolts is tightly pressed against the outer surface of the lower triangular seat, and then the adjusting bolts are tightened to achieve support and locking of the lower side of the upper triangular seat.

[0015] Optionally, the lower triangular seat is provided with two positioning through holes for the adjustment bolts to pass through, and the overall contour of the waist-shaped adjustment through hole is arc-shaped. During the rotation of the upper triangular seat, the positioning through hole can coincide with the waist-shaped adjustment through hole.

[0016] By adopting the above technical solution, the adjusting bolt can be inserted into the corresponding positioning hole after passing through the waist-shaped adjusting hole, so as to better fix and limit the rotation angle between the upper triangular seat and the lower triangular seat, and reduce the possibility of the upper triangular seat and the lower triangular seat being loosened in the locked state.

[0017] Optionally, the plurality of mounting through holes are evenly distributed around the axis of the flange base.

[0018] By adopting the above technical solution, the installation stability of the flange base fixed to the surface to be installed is improved.

[0019] Optionally, a fixing through hole is provided on the steel pipe seat, and a fixing bolt is provided on the side surface of the steel pipe seat, which passes through the fixing through hole and the steel pipe in sequence.

[0020] By adopting the above technical solution, a fixing bolt can be used to penetrate the fixing through hole and the steel pipe placed in the fixing cavity, thereby realizing the assembly and fixation of the steel pipe and the steel pipe seat, and facilitating the disassembly and assembly between the steel pipe seat and the steel pipe.

[0021] Optionally, the fixing through hole is a waist-shaped hole.

[0022] By adopting the above technical solution, it is easy to adjust the depth of the steel pipe placed inside the fixed cavity, thereby improving the performance of the movable base.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Due to the coordinated arrangement of the steel pipe seat and the flange base, during the installation process of the lower end of the steel pipe and the ground, the flange base can be fixed to the ground in advance by passing the expansion screws through the installation through-hole, and then the lower end of the steel pipe can be placed and fixed in the fixing cavity; this not only facilitates the subsequent disassembly and fixation of the steel pipe, but also strengthens the connection strength between the lower end of the steel pipe and the ground, reducing the impact of severe weather such as strong winds on the fixed steel pipe.

[0025] 2. Due to the coordinated arrangement of the upper triangular seat, the lower triangular seat and the adjusting piece, when the movable base is used on a sloped concrete floor, the angle between the flange base and the steel pipe seat can be adjusted according to actual conditions, and then the two can be limited and locked by the adjusting piece, thereby improving the applicability of the movable base.
