Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixed bases, in particular to an assembled building fixed base. Background Art
[0002] The prefabricated fixed base of modern buildings is a building foundation structure assembled with prefabricated components. Compared with the traditional cast-in-place foundation, the prefabricated fixed base has the advantages of fast construction speed, reliable quality, energy saving and environmental protection. The main components of the prefabricated fixed base are usually prefabricated in the factory and then transported to the construction site for assembly. These components can be made of different materials, such as concrete, steel, etc. At the construction site, these components are assembled together through reliable connection methods to form a stable building foundation. The design of the prefabricated fixed base needs to consider factors such as geological conditions and building requirements to ensure the bearing capacity and stability of the foundation. At the same time, it is also necessary to consider the durability, waterproofness, seismic resistance and other requirements of the foundation. In general, the prefabricated fixed base of modern buildings is an efficient, reliable and environmentally friendly building foundation structure suitable for construction projects of all sizes.
[0003] However, after the fixed base is installed on the ground, concrete needs to be poured into the fixed base and the foundation pit, which is commonly known as grouting. However, due to the small gap between the fixed base and the foundation pit, the concrete cannot be vibrated by a conventional oscillator, so that the bubbles in the concrete cannot be discharged before solidification, and then after the concrete solidifies, voids of varying numbers and sizes are generated. The voids formed in the concrete due to the bubbles reduce the reliability of the connection between the fixed base and the foundation pit. In order to solve this technical problem, the utility model proposes an assembled building fixed base. Utility Model Content

Due to the centrifugal force caused by the rotation of the camshaft, it vibrates, and the amplitude of the vibration increases with the increase of the rotation speed of the rotating shaft, so that the outer shell and the inner shell can be driven to vibrate as a whole, and the concrete can be vibrated to expel the bubbles inside, thereby solving the problem that the cavities formed by the bubbles in the concrete reduce the reliability of the connection between the fixed base and the foundation pit.
[0015] In the utility model, through the cooperation between the directional rail, the inner shell, the rotating shaft, the camshaft and the slide groove, the directional rail can move along the track given by the directional rail through the slide groove when rotating with the rotating shaft as the center.

DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1-4 As shown, an assembled building fixed base includes an outer shell 1 and an inner shell 2, the inner shell 2 is fixedly installed on the inner bottom wall of the outer shell 1, a motor 3 is arranged inside the inner shell 2, the output end of the motor 3 is fixedly connected to a rotating shaft 4, the outer surface of the rotating shaft 4 is fixedly connected to a camshaft 5, the outer surface of the camshaft 5 is slidably connected to the inner wall of the inner shell 2, the outer shell 1 can be installed in a foundation pit, and the inner shell 2 is installed on the inner bottom wall of the outer shell 1, which can increase the weight of the outer shell 1, so that it can sink in the concrete and increase the contact area with the concrete, and after grouting, the motor 3 is turned on, and the motor 3 can drive the camshaft 5 to rotate gradually and quickly through the rotating shaft 4, and the centrifugal force caused by the rotation of the camshaft 5 causes it to vibrate, and the amplitude of the vibration increases with the increase of the rotation speed of the rotating shaft 4, so that the outer shell 1 and the inner shell 2 can be driven to vibrate as a whole, and the concrete can be vibrated to discharge the bubbles inside, thereby solving the problem that the cavities formed by bubbles in the concrete reduce the connection reliability between the fixed base and the foundation pit.
[0023] The inner side of the outer shell 1 is provided with several downwardly protruding grooves 6, the outer surface of the inner shell 2 is fixedly connected with an insertion rod 7, the outer surface of the insertion rod 7 and the outer surface of the groove 6 are plug-in connected to each other, and a rubber layer is installed on the inner wall and the inner bottom wall of the groove 6. The rubber layer can protect the groove 6 to avoid damage to the groove 6 due to excessive downward speed when the inner shell 2 is installed downward.
[0024] Four slideways 8 are fixedly installed on the inner wall of the outer shell 1, and a wheel seat 9 is fixedly connected to the outer surface of the inner shell 2. An inlay wheel 10 is installed inside the wheel seat 9. The outer surface of the inlay wheel 10 is slidably connected to the outer surface of the slideway 8. When the inner shell 2 moves downward into the outer shell 1, it can slide on the slideway 8 through the wheel seat 9 and the inlay wheel 10, thereby reducing the friction between the inner shell 2 and the outer shell 1, and when the inner shell 2 vibrates, the vibration can be transmitted to the outer shell 1 through the wheel seat 9, the inlay wheel 10 and the slideway 8, thereby avoiding the situation where the inner shell 2 vibrates and causes the inner shell 2 to move or rotate by itself in the outer shell 1.
[0025] The inner wall of the outer shell 1 is fixedly connected with several fixing seats 11, and the outer surface of the inner shell 2 is fixedly connected with several fixing seats 2 12.

The outer surface of the screw 13 is threadedly connected with a nut. When the inner shell 2 is installed inside the outer shell 1, the fixing seat 11 and the fixing seat 2 12 can be connected to each other. The fixing seat 11 and the fixing seat 2 12 can be installed together through the screw 13 and the nut, which makes the inner shell 2 easier to install and is beneficial for the inner shell 2 to transmit vibration to the outer shell 1.
[0026] A square groove 14 is provided on the inner side of the outer shell 1, and a convex groove 15 is fixedly connected to the bottom surface of the inner shell 2. The outer surface of the square groove 14 and the outer surface of the convex groove 15 are slidably connected to each other. When the inner shell 2 is installed downward, the convex groove 15 can be inserted into the square groove 14, thereby further increasing the contact area between the outer shell 1 and the inner shell 2, and making the propagation of vibration more sensitive. At the same time, only when the convex groove 15 is embedded in the square groove 14, the fixing seat 11 and the fixing seat 2 12 can be connected to each other, thereby further reducing the difficulty of installation.
[0027] The inner wall of the inner shell 2 is fixedly connected with a load-bearing plate 16, and the outer surface of the load-bearing plate 16 is fixedly installed with a mounting frame 17. The motor 3 is installed on the outer surface of the mounting frame 17. The outer surface of the rotating shaft 4 is rotatably connected to the inner wall of the load-bearing plate 16. The load-bearing plate 16 can provide support for the motor 3 through the mounting frame 17. A bearing is installed inside the load-bearing plate 16, and the bearing is sleeved on the outer surface of the rotating shaft 4, thereby making the rotating shaft 4 more sensitive and stable when rotating.
[0028] An oriented rail 18 is fixedly connected to the inner wall of the inner shell 2 below the load-bearing plate 16, and a slide groove 19 is provided on the inner side of the camshaft 5. The outer surface of the oriented rail 18 and the outer surface of the slide groove 19 are slidably connected to each other. When the oriented rail 18 rotates with the rotating shaft 4 as the center, it can move along the track given by the oriented rail 18 through the slide groove 19. The oriented rail 18 and the slide groove 19 can reduce the possibility of the camshaft 5 being misaligned or deviating from the track when rotating at high speed, thereby making the device more stable when in use.
