Description

Technical Field

[0001] The invention relates to the technical field of folding houses, and in particular to a preassembled folding house. Background Art

[0002] In the field of modern construction, with the growing demand for temporary living space, emergency housing and mobile building facilities, double-wing folding expansion houses have emerged. This type of house is in great demand in scenes such as temporary dormitories at construction sites, field operation camps, and disaster relief settlements due to its foldable, easy to transport and quick deployment characteristics.

[0003] However, the existing double-wing folding expansion room has many problems in practical application. From the perspective of installation after transportation, on the one hand, if the manual installation method is adopted, due to the complex structure of the double-wing folding expansion room, the large number of parts and the large size, it often requires a lot of manpower to carry out collaborative work, which consumes a lot of time and labor costs.

[0004] On the other hand, in order to overcome the drawbacks of manual installation, some designs try to introduce automated drive structures to assist in the installation process of the double-wing folding expansion room. Although this method reduces the direct involvement of manpower to a certain extent, the design, manufacture and installation of the automated drive structure itself requires a certain amount of cost investment. At the same time, the introduction of automated equipment also increases the complexity of the entire system, making subsequent maintenance work cumbersome. Once the automated drive system fails, professional technicians and specific maintenance equipment are required for maintenance. Moreover, the complex automated drive structure is easily damaged during long-term use due to the influence of harsh outdoor environments such as wind and sand erosion, rain soaking, temperature changes, etc., which reduces the possibility of long-term reuse of the folding house.

[0005] In addition, during the design and manufacturing process of the folding house, in order to achieve the folding function, the connection method between the wall panels is often quite special. During the use of the house, affected by factors such as wind load, vibration, temperature deformation, etc., the connection parts between the wall panels are prone to loosening, enlarged gaps, or even cracking, which shortens the service life of the folding house. Summary of the invention

[0058] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0059] Reference Figures 1 to 11 , which is the first embodiment of the present invention, proposes a prefabricated folding house, including a main body 1; a folding unit 2 is arranged on the main body 1, and the folding unit 2 forms an avoidance gap 20 after being folded; a support beam 3 is arranged in the avoidance gap 20; a first gasket 4 is arranged between the support beam 3 and the folding unit 2; a second gasket 5 is arranged on the support beam 3; a fastener 6 passes through the first gasket 4 and the second gasket 5 to connect the support beam 3 and the folding unit 2.

[0060] In this embodiment, the folding unit 2 is mounted on the main body 1, and each part of the folding unit 2 is connected in a rotatable manner, such as using a hinge, so that an avoidance gap 20 can be formed after folding. The support beam 3 is a metal square tube, which is placed according to the shape and size of the avoidance gap 20 formed by the folding unit 2. The first gasket 4 is made of a metal sheet and is placed between the support beam 3 and the folding unit 2. The second gasket 5 is made of a metal sheet and is mounted on the support beam 3. The first gasket 4 has a threaded hole, and the second gasket 5 has a round hole. The fastener 6 is a combination of a screw and a washer. The screw passes through the first gasket 4, the folding unit 2, the second gasket 5 and the support beam 3 in turn and is tightened to connect the support beam 3 and the folding unit 2.

[0061] The first gasket 4 and the second gasket 5 in this embodiment connect the support beam 3 and the folding unit 2, enhance the stability of the overall structure, enable the various components to work together, prevent local loosening or displacement, and ensure the safety and reliability of the house during use. The first gasket 4 buffers the pressure and friction between the support beam 3 and the folding unit 2, reduces component wear, prolongs service life, and can reduce the noise caused by component friction to a certain extent, thereby improving living comfort. This embodiment is a light steel dense rib plus integrated wall structure.

[0062] Furthermore, the support beam 3 is a hollow square tube, and the support beam 3 has a mounting opening, and the second gasket 5 passes through the mounting opening and enters the interior of the support beam 3 .

[0063] In this embodiment, the support beam 3 is made of a hollow square tube material to reduce the overall weight of the house, and a mounting opening is processed on one side of the square tube. When installing the second gasket 5, the second gasket 5 is inserted into the hollow square tube from the mounting opening and adjusted to a predetermined position, corresponding to the first gasket 4, to connect the support beam 3 and the folding unit 2, and the folding unit 2 and the main body 1 are also connected in this way.

[0064] The hollow square tube structure reduces the weight of the support beam 3 while ensuring a certain strength, making it easier to transport and install, reducing the weight of the entire house, reducing the bearing requirements for the foundation, and expanding the scope of application. The design of the second gasket 5 passing through the installation opening and entering the interior makes the connection between the fastener 6 and the support beam 3 more stable, effectively preventing the first gasket 4 and the second gasket 5 from being displaced or falling off during use, and further improving the stability of the connection.

[0065] Furthermore, it also includes a first pad foot 7, which has a plurality of first pad feet 7, each of which has a first horizontal portion 71 and a first vertical portion 72, the first vertical portion 72 is arranged on the support beam 3, and the first horizontal portion 71 is flush with the lower end surface of the support beam 3; there are a plurality of second pad feet 8, each of which has a second horizontal portion 81 and a second vertical portion 82, the second vertical portion 82 has a mounting hole 83, the second vertical portion 82 is arranged on the folding unit 2 through the mounting hole 83, and the second horizontal portion 81 is flush with the lower end surface of the support beam 3.

[0066] In this embodiment, the number and distribution positions of the plurality of first feet 7 are determined according to the length and width of the support beam 3. The first vertical portion 72 is fixed to a specific position of the support beam 3 by welding, ensuring that the first horizontal portion 71 and the lower end surface of the support beam 3 remain horizontally collinear. The first horizontal portion 71 has a fixing hole for fixing to concrete to strengthen the overall structure of the house. The second vertical portion 82 is fixed to the folding unit 2 by rivets, bolts, etc., so that the second horizontal portion 81 is flush with the lower end surface of the support beam 3 and collinear. The second horizontal portion 81 has a fixing hole for fixing to concrete.

[0067] The first foot 7 and the second foot 8 support the support beam 3 and the folding unit 2 from multiple positions, increasing the contact area between the bottom of the house and the ground or the supporting plane, improving the stability of the overall structure, and preventing the house from tilting or shaking due to uneven ground or uneven force. The first horizontal portion 71 and the second horizontal portion 81 are in contact with concrete, which facilitates installation and disassembly while also enhancing the overall stability of the house.

[0068] Furthermore, one end of the top plate 21 is rotatably set on the top edge of the main body 1; one end of the bottom plate 22 is rotatably set on the bottom edge of the main body 1; the first side plate 23 is rotatably set on the other end of the bottom plate 22, and the bottom plate 22 and the first side plate 23 form an avoidance gap 20. After the first side plate 23 is rotated, it is used to abut against the other end of the top plate 21; there are two second side plates 24, and the second side plates 24 are rotatably set on the side edge of the main body 1, and are respectively located on both sides of the main body 1. After the bottom plate 22, the first side plate 23 and the second side plate 24 are rotated, they are used to form a square structure, and the first gasket 4 is located between the support beam 3 and the bottom plate 22 and / or the first side plate 23.

[0069] In this embodiment, one end of the top plate 21 is connected to the top edge of the main body 1 by a hinge. One end of the bottom plate 22 is connected to the bottom edge of the main body 1 by a hinge. The first side plate 23 is connected to the bottom plate 22 by a hinge. When unfolded, the bottom plate 22 and the first side plate 23 naturally form an avoidance gap 20. The two second side plates 24 are installed on the two side edges of the main body 1 by hinges. After unfolding, the bottom plate 22 and the top plate 21 are also connected to the first side plate 23 and the second side plate 24 by the first gasket 4 and the second gasket 5. After unfolding, the first side plate 23 and the top plate 21 are also connected by the first gasket 4 and the second gasket 5. After unfolding, the top plate 21 and the first side plate 23, the top plate 21 and the second side plate 24, and the first side plate 23 and the second side plate 24 are also connected by the first gasket 4, the second gasket 5 and the fastener 6.

[0070] The design of the folding unit 2 enables the house to achieve a convenient folding function, greatly saving space during transportation and storage, reducing transportation costs and storage difficulties, and improving the flexibility of the house. The rotational connection and matching between the top plate 21, the bottom plate 22, the first side plate 23 and the second side plate 24 enable the house to be quickly built to form a stable spatial structure when it is unfolded for use, which is convenient for users to use and improves the efficiency of use. This embodiment uses a pre-assembled box structure, which is folded and unfolded as a whole, adopts a light steel frame, and is supported by dense ribs. The wall is pre-assembled at the factory, saving subsequent installation time.

[0071] Furthermore, one end of the first rotating arm 9 is rotatably set on the side of the top plate 21; one end of the second rotating arm 10 is rotatably set on the main body 1; the other end of the first rotating arm 9 is set on the flip-up optional stop component 11, and the other end of the second rotating arm 10 is set on the flip-up optional stop component 11.

[0072] In this embodiment, the first rotating arm 9 and the second rotating arm 10 are made of metal, such as aluminum alloy or steel, and are designed with appropriate lengths and shapes according to the structures of the top plate 21 and the main body 1. One end of the first rotating arm 9 is rotatably set at a predetermined position on the top plate 21, and one end of the second rotating arm 10 is connected to a corresponding position on the main body 1 in the same manner. The flip-up free stop assembly 11 has the same structure as professional free stop accessories for doors and windows, and is a prior art.

[0073] The application of the flip-up and stop assembly 11 provides the top plate 21 with a multi-angle hovering function. When unfolding the folding house, the flip-up and stop assembly 11 can be used to achieve single-person operation without the need for cooperation from multiple people, which speeds up the assembly process and does not require additional support tools during assembly, thereby improving operational convenience.

[0074] Furthermore, there are two swing rods 12, and the two swing rods 12 are located on both sides of the main body 1. One end of the swing rod 12 is swingably set on the main body 1; one end of the support rod 13 is swingably and slidably set on the swing rod 12, and the other end is swingably and slidably set on the top plate 21. The support rod 13 is used to support the top plate 21 to a horizontal state. The support rod 13 is a telescopic rod. The swing rod 12 has a slide groove 121, and the slide groove 121 has a first section 122, a second section 123 and a third section 124. The first section 122 and the third section 124 are both arranged vertically with the second section 123, and the first section 122 and the third section 124 are located on the same side of the second section 123. One end of the support rod 13 is swingably and slidably set in the second section 123. The first section 122 and the third section 124 have teeth 125, and the bottom plate 22 and the main body 1 both have a fixed groove 22 1, the rotating rod 14 is rotatably arranged on the supporting rod 13, and the rotating rod 14 has an arc-shaped guide groove 141; the gear 15 is arranged on the rotating rod 14, and the gear 15 is used to mesh with the teeth 125; the plug-in column 16 is slidably arranged in the rotating rod 14, and the plug-in column 16 has a guide protrusion 161, and the guide protrusion 161 is slidably arranged in the arc-shaped guide groove 141. After the rotating rod 14 rotates, the plug-in column 16 is driven to slide, and the plug-in column 16 is used to be stuck in the fixing groove 221. The two ends of the cross bar 17 are detachably arranged on the two supporting rods 13; the handle 18 is rotatably arranged on the cross bar 17, and after the handle 18 is rotated, it is used to pull the cross bar 17. The swing rod 12 is rotatably and slidably arranged on the main body 1, and the support beam 3 is arranged on the other end of the swing rod 12.

[0075] In this embodiment, the swing rod 12 is made of metal material, swings and slides on both sides of the main body 1. After the bottom plate 22 is unfolded, the swing rod 12 is located on both sides of the bottom plate 22. The support rod 13 adopts a telescopic rod structure. A slide groove 121 with a first section 122, a second section 123 and a third section 124 is processed on the swing rod 12. One end of the support rod 13 is swung and slidably set in the second section 123, so that the support rod 13 can slide and adjust its position in the horizontal direction. After the teeth 125 of the first section 122 and the third section 124 are processed, a fixing groove 221 is processed at the corresponding positions of the bottom plate 22 and the main body 1. The rotating rod 14 is rotatably set on the support rod 13 by means of a bearing or the like. The gear 15 is installed on the rotating rod 14 so that it can mesh with the teeth 125. At the same time, a sliding plug-in column 16 is set in the rotating rod 14, and an arc-shaped guide groove 141 is processed on the rotating rod 14. The guide protrusion 161 of the plug-in column 16 is embedded in the arc-shaped guide groove 141. After the rotating rod 14 rotates, the plug-in column 16 is driven to be inserted into or pulled out of the fixing groove 221 through the arc guide groove 141 to achieve locking. When unfolding, the support rod 13 and the bottom plate 21 are locked. After folding, the support rod 13 and the main body 1 are locked to prevent the support rod 13 from accidentally unfolding. The cross bar 17 is detachably and height-adjustably installed on the two support rods 13 to ensure that the two support rods 13 move synchronously.

[0076] The combined structure of the swing rod 12 and the support rod 13 provides a reliable support mechanism for the top plate 21. When installing the folding house, one person can complete the installation of the folding house without the cooperation of multiple people. The cooperation of the slide 121, the teeth 125, the rotating rod 14, the gear 15 and the plug-in column 16 realizes the locking of the support rod 13, prevents the support rod 13 from being accidentally misplaced, and causes the top plate 21 to be unstable. The support rod 13 cooperates with the upward random stop assembly 11 to achieve the effect of one person installing the folding house.

[0077] Working process:

[0078] During installation, the support rod 13 is first slid out of the first section 122 and into the second section 123. The plug-in column 16 is disengaged from the fixing groove 221 during the process of the support rod 13 sliding out of the first section 122. The fixing groove 221 in this embodiment is a long groove with a certain position margin. After the plug-in column 16 slides out of the fixing groove 221, it is unlocked and the swing rod 12 is swung so that the swing rod 12 is in a horizontal state and overlapped on the ground. Then the top plate 21 is lifted up, and the flip-up stop assembly 11 takes effect, so that the top plate 21 is fixed at a certain height. The worker controls the bottom end of the support rod 13 to slide in the second section 123 through the handle 18 on the cross bar 17 until it slides to a position close to the third section 124, and then the worker returns to the position close to the main body 1. On one side, the control handle 18 drives the two support rods 13 to move synchronously through the cross bar 14, so that the upper end of the support rod 13 slides along the top plate 21, and the support rod 13 slides to the edge of the top plate 21. The support rod 13 is just retracted to the shortest and is in a vertical state. The top plate 21 is lifted, and after the bottom plate 22 and the first side plate 23 are unfolded, the bottom end of the support rod 13 is controlled to slide into the third section 124, and the gear 15 and the teeth 125 are engaged. During the sliding process, the plug-in column 16 slides into the fixed groove 221 to fix the swing rod 12. The swing rod 12 slides on the main body 1 to adapt to the bottom plates 22 of different widths. It is not in a state of continuous sliding and requires manual adjustment. The folding method and the unfolding method have opposite operating steps.
