Description

Technical Field

[0001] The utility model relates to the technical field of housing construction, and particularly relates to a bottom frame of a prefabricated house. Background Art

[0002] A prefabricated house is a building assembled using prefabricated house components, which has the advantages of short construction period and low weight. A prefabricated house mainly consists of a bottom frame, a wall frame, and a roof frame. Among them, the bottom frame, as an important component of the prefabricated house, bears the foundation of the entire house, and its structure requires strong stability and layout.

[0003] In related prior art, such as the bottom frame structure of a movable house with the publication number of CN219604546U, it includes: support feet and a supporting plate frame. Among them, a limiting convex column is arranged on the top surface of the support feet, a vertically penetrating sleeving hole is opened on the supporting plate frame, the sleeving hole is sleeved on the limiting convex column, and the supporting plate frame is pressed on the top surface of the support feet. The upper end of the limiting convex column protrudes from the sleeving hole and forms a nested convex part; when installing this bottom frame structure, bolts are not required for locking, so that the installation and disassembly efficiency can be improved during disassembly and assembly, the labor intensity of workers can be reduced, and the requirements for quick use, quick disassembly and transfer can be met.

[0004] However, in the above solution, both the supporting plate frame and the supporting pipe body are sleeved on the limiting convex column, and the supporting plate frame is located on the top of the supporting pipe body. By sleeving supporting pipe bodies with different heights, the installation height of the supporting plate frame can be adjusted. When replacing the supporting pipe body with a different height, it is necessary to detach the supporting plate frame from the limiting convex column, then detach the original supporting pipe body, and finally sleeve the new supporting pipe body and the supporting plate frame on the limiting convex column in sequence. This process has many steps and is not convenient for adjusting the installation height of the supporting plate frame. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a bottom frame of a prefabricated house with low weight, which can facilitate the adjustment of the installation height.

[0006] To achieve the above purpose, a bottom frame of a prefabricated house with low weight is provided, which includes: support legs. Four support legs are arranged at intervals in a rectangle. The support legs include a base and a hollow column. The column is located on the top of the base; heightening members. The heightening members are located on the top of the base and are slidably sleeved on the columns. The heightening members are composed of two cushion blocks. One end of the cushion block is provided with a convex block, and the other end of the cushion block is provided with a groove that cooperates with the convex block. The convex block and the groove of one cushion block are connected with the corresponding groove and convex block of the other cushion block; connecting sleeves. The connecting sleeves are located on the top of the heightening members and are sleeved on the support legs; a hollow main beam. A main beam is arranged between adjacent support legs, and both ends of the main beam are connected with the corresponding connecting sleeves.

[0007] Working principle and effect of the above solution: Both the upright column and the main beam are of hollow structure, which can reduce their own weight. When installing this chassis structure, place one cushion block on the top of the base, place the other cushion block on the top of this cushion block and slide it downwards so that the convex block of the other cushion block matches the groove of one cushion block, and the convex block of one cushion block matches the groove of the other cushion block. At this time, the two cushion blocks are spliced to form a heightening piece. The heightening piece is sleeved on the upright column, and the connecting sleeve is sleeved on the upright column. The connecting sleeve is located at the top of the heightening piece. Place the main beam between the two legs, and both ends of the main beam are connected to the corresponding connecting sleeves. When replacing heightening pieces of different heights, use tools to lift the connecting sleeve and the main beam so that there is a certain gap between the base and the connecting sleeve. Slide one cushion block upwards to disconnect the convex block and the groove between the cushion blocks, so that this heightening piece can be removed. Assemble the new cushion blocks on the outside of the upright column to form a new heightening piece. Finally, remove the tools so that the connecting sleeve is located at the top of the heightening piece.

[0008] By setting the heightening piece, which is spliced by two cushion blocks, when adjusting the installation height, lift the connecting sleeve and the main beam, and the cushion blocks of the original heightening piece can be removed one by one. Then assemble the two cushion blocks of the new heightening pad together and sleeve the new heightening pad on the outside of the upright column. During this process, it is not necessary to detach the connecting sleeve from the upright column, which can reduce the working steps when replacing the heightening piece and facilitate adjusting the installation height of the main beam.

[0009] According to the described low-weight prefabricated house chassis, installation holes are provided at the top of the base, and the bottom of the upright column is slidably inserted into the installation holes. A damping spring is arranged in the installation holes, and both ends of the damping spring are respectively connected to the bottom of the installation hole and the bottom of the upright column.

[0010] By setting the damping spring, when the base is vibrated, the upright column slides up and down along the installation hole, and the damping spring is compressed or stretched. During this process, the damping spring can slow down the vibration energy transmitted from the base to the upright column.

[0011] According to the described low-weight prefabricated house chassis, a limiting column with a T-shaped cross-section is provided at the bottom of the installation hole, and a limiting cylinder is provided at the bottom of the upright column. The limiting cylinder is slidably sleeved on the limiting column, and the damping spring is sleeved on the limiting cylinder.

[0012] By setting the T-shaped limiting column, when the upright column slides up and down, the limiting cylinder slides between the bottom of the installation hole and the top of the limiting column, which can limit the sliding range of the limiting cylinder.

[0013] According to the described low-weight prefabricated house chassis, mounting blocks are provided on two adjacent outer sides of the connecting sleeve, and mounting grooves are provided in the mounting blocks. Both ends of the main beam are located in the corresponding mounting grooves.

[0014] When installing the main beam, place both ends of the main beam in the installation grooves of the corresponding connection sleeves.

[0015] According to the described low-weight prefabricated house chassis, connection columns are provided at the bottom of the installation grooves, and connection holes matching the connection columns are provided at both ends of the main beam.

[0016] By providing connection columns, when both ends of the main beam are located in the installation grooves, the connection columns cooperate with the connection holes, and both ends of the main beam are connected to the connection columns, thereby restricting the main beam from rotating in all directions.

[0017] According to the described low-weight prefabricated house chassis, a first reinforcing rib is provided between the bottom of the installation block and the bottom of the connection sleeve.

[0018] By providing the first reinforcing rib, the connection between the installation block and the connection sleeve can be strengthened.

[0019] According to the described low-weight prefabricated house chassis, a second reinforcing rib is provided between the bottom and the top of the base.

[0020] By providing the second reinforcing rib, the connection between the bottom and the top of the base can be strengthened.
