Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a novel expandable drainage and waterproof container house. Background Technology
[0002] Container houses are movable and reusable building products made from shipping containers as the base material or modified and designed based on their specifications. They originated from the modification and reuse of old shipping containers. Structurally, they are based on container units welded with special steel profiles, combined with enclosure structures such as color steel composite panels, and can be arranged in single or multiple container combinations.
[0003] Traditional container houses typically have simple drainage systems, making them prone to water accumulation, which can lead to roof corrosion and leaks, affecting the lifespan and safety of the house. Furthermore, existing container houses have limitations in terms of expandability, making it difficult to flexibly adjust the size and layout to meet specific needs.
[0004] To address these issues, we offer a new type of expandable, drainage- and waterproof container house. Utility Model Content
[0005] The purpose of this utility model is to provide a new type of expandable, drainage and waterproof container house to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel expandable drainage and waterproof container house, including a base frame, a three-way connector on one side of the base frame, and a functional mechanism on the top of the base frame;
[0007] The functional mechanism includes an outer wall assembly installed at the top of the base frame, an extension assembly installed on one side of the base frame, and drainage assemblies installed at the four corners of the top of the base frame.
[0008] Preferably, the exterior wall assembly includes an L-shaped buckle fixedly connected to the inside of the base frame, one side of the L-shaped buckle is engaged with an exterior wall panel, and the top of the exterior wall panel is connected by a fixing bolt.
[0009] Preferably, the expansion assembly includes a connecting tube disposed on the other side of the base frame, with an expansion tube nested on one side of the connecting tube, and the connecting tube and the expansion tube are locked and fixed by at least two bolts and nuts passing through corresponding holes.
[0010] Preferably, the drainage assembly includes a riser fixedly connected to the top of the tee connector, a top plate fixedly connected to the top of the riser, a drainage trough laid on the upper surface of the top plate, a diversion trough fixedly connected to both ends of the drainage trough, an opening at both ends of the diversion trough, and a drainage pipe fixedly connected to the bottom end of the opening.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This utility model, through the setting of the external wall components, facilitates the assembly of the house by fastening the external wall panels into the clips and then fixing them with bolts during installation. The setting of the expansion components allows for flexible adjustment of the house's area and layout according to actual needs. The setting of the drainage components can effectively discharge rainwater and other water, thereby avoiding water accumulation on the roof due to poor drainage systems, which can lead to roof corrosion and leakage, affecting the service life and safety of the house.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 As shown, a new type of expandable drainage and waterproof container house includes a base frame 1, a three-way connector 2 on one side of the base frame 1, and a functional mechanism 3 on the top of the base frame 1.
[0020] The functional mechanism 3 includes an exterior wall component 31 installed at the top of the base frame 1, an extension component 32 installed on one side of the base frame 1, and drainage components 33 installed at the four corners of the top of the base frame 1. The exterior wall component 31 facilitates the installation of the exterior wall. The extension component 32 allows the house to be expanded as needed, improving the flexibility of the house. The drainage components 33 effectively drain rainwater and prevent water accumulation on the roof.
[0021] Furthermore, the exterior wall component 31 includes an L-shaped buckle 311 fixedly connected to the inside of the base frame 1. One side of the L-shaped buckle 311 is attached to the exterior wall panel 312. The top of the exterior wall panel 312 is connected by a fixing bolt 313. The L-shaped buckle 311 can be used to position the exterior wall panel 312 during installation. Then, the top is fixed to the roof frame by the fixing bolt 313, which facilitates the assembly of the house.
[0022] Furthermore, the extension assembly 32 includes a connecting pipe 321 disposed on the other side of the base frame 1. An extension pipe 322 is nested on one side of the connecting pipe 321. The connecting pipe 321 and the extension pipe 322 are locked and fixed by at least two bolts and nuts passing through corresponding holes. The connecting pipe 321 can be used to extend the house in conjunction with the extension pipe 322, thereby improving the flexibility of house use.
[0023] Furthermore, the drainage component 33 includes a riser 331 fixedly connected to the top of the tee connector 2. A top plate 332 is fixedly connected to the top of the riser 331. A drainage trough 333 is laid on the upper surface of the top plate 332. A diversion channel 334 is fixedly connected to both ends of the drainage trough 333. An opening is opened at both ends of the diversion channel 334. A drainage pipe 335 is fixedly connected to the bottom end of the opening. The riser 331 can be used to support the roof. The top plate 332 can be used to support the drainage trough 333. The drainage trough 333 can divert rainwater into the diversion channel 334 and then discharge it through the drainage pipe 335, preventing water accumulation on the roof and also preventing rainwater from falling from all directions and affecting its use.
[0024] Working principle: During installation, the base frame 1 and the riser 331 can be connected through the three-way connector 2. The outer wall panel 312 can be positioned through the L-shaped buckle 311 and then fixed to the top bracket through the fixing bolt 313. When expansion is required, the connecting pipe 321 can be installed on the base frame 1 and then the expansion pipe 322 can be connected to expand the house. When drainage is required, rainwater will fall into the drainage channel 333. Under the action of gravity, the rainwater will flow along the drainage channel 333 into the diversion channel 334, and then fall into the drainage pipe 335 through the hole at the bottom of the diversion channel 334, and then be discharged to the ground through the drainage pipe 335. This completes the installation process of a new type of expandable drainage and waterproof container house.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
