Description

Technical Field

[0001] The present invention relates to the field of prefabricated temporary houses, and specifically to a prefabricated temporary house structure with variable space. Background Art

[0002] For existing temporary house structures, for the convenience of disassembly and reuse, prefabricated structures are generally selected to achieve the rapid installation and disassembly of temporary houses, reducing the construction period and cost of temporary houses, and are widely used in fields such as construction or temporary hospitals. For existing prefabricated houses, most of their spaces are fixed. According to different usage requirements, when the number of people or equipment increases midway, the space cannot be adjusted, and additional construction is required. The construction of new houses delays time and cannot meet the suddenly increased usage requirements, making the use of temporary houses unable to meet the needs of different people or sudden situations, and its practical effect needs to be further improved. Summary of the Invention

[0003] The purpose of the present invention is to provide a prefabricated temporary house structure with variable space, which can quickly adjust the house area, meet the needs of different people or other suddenly increased usage requirements, is convenient for disassembly and assembly, has higher construction efficiency, and does not occupy additional space during normal use, further improving its practical application effect.

[0004] To achieve the above object, the present invention is realized through the following technical solutions:

[0005] A prefabricated temporary house structure with variable space, including an inner box body. The longitudinal section of the inner box body is in a shape of a Chinese character 'hui'. One side of the inner box body is provided with a door panel, and the other side of the inner box body is detachably connected with a closing component. The outer side of the inner box body is sleeved with a detachable outer box body. After the outer box body is disassembled, it is a structure of the same size communicating with the inner box body. The outer box body includes a top plate and symmetrically arranged side plates. The two side plates are symmetrically and slidably connected to the bottom of the top plate. The top plate is symmetrically provided with adjusting rods for cooperating with the side plates. Anchor bolt holes are provided at corresponding positions on the bottom of the side plates and on the inner box body. The closing component includes a plurality of foldable and retractable blocking plates. The plurality of blocking plates are rotatably connected end to end. The blocking plate at the end close to the inner box body is rotatably connected to the bottom of the inner box body. After the plurality of blocking plates are folded, they are detachably connected to the side surface of the side plate before disassembly. After the plurality of blocking plates are unfolded, the blocking plate at the end far from the inner box body is detachably connected to the side surface of the side plate after disassembly in the vertical direction, and the remaining blocking plates are detachably connected to the bottom of the side plate after disassembly in the horizontal direction.

[0006] Furthermore, on both sides of the inner box body close to the bottom, fixing grooves are symmetrically provided. The bottom of the side plate is provided with a bottom fixing plate, and the bottom fixing plate is slidably connected in the fixing groove. The anchor bolt holes are arranged at corresponding positions on the side wall of the fixing groove and the bottom fixing plate.

[0007] Furthermore, side fixing plates are symmetrically arranged on both sides of the plugging plate. Outer fixing holes are provided on the side fixing plates. After the side plates are disassembled, the outer fixing holes are aligned with the anchor bolt holes on the bottom fixing plate.

[0008] Furthermore, inner fixing holes are provided on the side surface of the side plate. Before the side plate is disassembled, the outer fixing holes are aligned with the inner fixing holes.

[0009] Furthermore, unfolding fixing holes are also provided on the end plugging plate away from the inner box body. After the side plate is disassembled, the unfolding fixing holes are aligned with the inner fixing holes.

[0010] Furthermore, convex plates are symmetrically arranged on both sides of the top plate. The adjusting rod passes through the convex plate and is connected to the side plate.

[0011] Furthermore, the adjusting rod is threadedly connected to the convex plate. The end of the adjusting rod penetrates through the convex plate and is rotatably connected to the side plate.

[0012] Furthermore, a plurality of guiding blocks are provided on the top of the side plate, and a plurality of guiding grooves are provided on the bottom of the top plate. The guiding blocks are slidably connected in the guiding grooves. After the side plate is disassembled, the guiding blocks move to the ends of the guiding grooves.

[0013] Furthermore, both the guiding blocks and the guiding grooves are T-shaped for matching use.

[0014] Furthermore, the loop-shaped side surfaces of the inner box body are all detachably connected.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The structure of the present invention includes a loop-shaped inner box body. One side of the inner box body is blocked by a door panel, and a closing component is arranged on the other side, thereby realizing the relative closure of the overall structure of the house and ensuring the normal use of the house structure. A detachable outer box body is sleeved outside the inner box body. After the outer box body is disassembled, a same-size structure communicating with the inner box body is formed, doubling the overall space of the temporary house, so as to quickly meet the sudden increase in the number of people or the placement of equipment, etc., greatly improving the effect of the temporary house in dealing with emergencies. And the whole outer box body is sleeved outside the inner box body during normal use, without occupying extra space, only increasing the thickness of the house, ensuring the normal use of the temporary house, greatly expanding the application range of the temporary house, and improving the adaptability to different environments;

[0017] 2. The outer box body includes a top plate and symmetrically arranged side plates. The side plates on both sides are symmetrically and slidably connected to the bottom of the top plate. An adjusting rod is used to adjust the position of the side plates relative to the top plate, so that the side plates can be sleeved on the sides of the inner box body during normal use. When the space is adjusted, the two side plates move relative to each other under the action of the adjusting rod until the distance between the two side plates is the same as the distance between the two side surfaces of the inner box body. Thus, the outer box body after disassembly has the same accurate size structure as the inner box body, making the internal space of the temporary house directly doubled in length on the original basis without changing the objects inside the original inner box body, and the space adjustment is more efficient and convenient. Anchor bolt holes are provided at the corresponding positions on the bottom of the side plates and on the inner box body. Such a structure enables the overall house structure to be fixed on the ground by the anchor bolts passing through the anchor bolt holes both before and after the space adjustment, making the disassembly and assembly steps simpler and more efficient, and the space adjustment more convenient and efficient.

[0018] 3. The closing assembly includes a plurality of collapsible and retractable blocking plates. The plurality of blocking plates are rotatably connected end to end, and the end blocking plate close to the inner box body is rotatably connected to the bottom of the inner box body. After the plurality of blocking plates are folded, they are detachably connected to the side surface of the side plate before disassembly. After the plurality of blocking plates are unfolded, the end blocking plate far from the inner box body is detachably connected to the side surface of the side plate after disassembly in the vertical direction, and the remaining blocking plates are detachably connected to the bottom of the side plate after disassembly in the horizontal direction. Such a structure enables one end of the outer box body after space adjustment to communicate with the inner box body. By rotating the closing assembly to the horizontal direction, it serves as the bottom structure of the outer box body, and the end blocking plate far from the inner box body rotates to the vertical direction to serve as the side structure of the outer box body, thus realizing the penetration and stable connection of the entire outer box body and the inner box body. By using the structure of the original house side as the source of space adjustment, it reduces the additional space occupancy rate of the outer box body, ensures the stability of the house structure before and after space adjustment, and greatly improves the convenience and practicality of space adjustment.

[0031] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by this application.

[0032] The present invention relates to a prefabricated temporary housing structure with variable space. The main structure includes an inner box body 1, which is generally made of metal material and serves as the overall structure of the housing to provide protection and support. The longitudinal section of the inner box body 1 is in a shape of a double-square, having structures on the upper, lower, left, and right sides. One side of the inner box body 1 is provided with a door panel 2, which is generally connected to one end of the inner box body 1 in a rotatable manner to control the opening and closing of one side of the housing structure. The other side of the inner box body 1 is detachably connected with a closing component, which can be connected to the inner box body 1 by means of detachable connection such as existing bolts. The door panel 2 and the closing component are arranged to close both ends of the double-square shape, thereby making the whole housing closed. An outer box body 3 is sleeved outside the inner box body 1 and is detachable. After being disassembled, the outer box body 3 has the same size as the inner box body 1 and is communicated with it. The structure of the outer box body 3 is sleeved outside the inner box body 1, and both are made of metal plates with the same thickness. When connected together, the outer box body 3 is sleeved outside the inner box body 1, only increasing the thickness of the inner box body 1 without occupying extra space and not disturbing the normal use of the inner box body 1. After being disassembled, it can be transferred to the end where the closing component of the inner box body 1 is located, and the disassembled closing component is used to close one end of the outer box body 3. After the other end of the outer box body 3 is communicated with the end of the inner box body 1, a housing structure communicated with the inner box body 1 is formed, doubling the length of the space, making the space adjustment more efficient and convenient, without disturbing the items and use in the original space of the inner box body 1, making the space adjustment more practical and convenient, meeting the sudden increase in the need for personnel or equipment placement, and improving the adaptability to different use environment requirements;

[0033] The outer box body 3 includes a top plate 4 and symmetrically arranged side plates 5, which are respectively sleeved on the top and side of the inner box body 1, without separately setting the closed structures at the bottom and ends. The two side plates 5 are symmetrically and slidably connected to the bottom of the top plate 4. The top plate 4 is symmetrically provided with adjusting rods 6 for cooperating with the side plates 5. With such a setting, when sleeved and connected to the inner box body 1, the two side plates 5 move in opposite directions through the adjusting rods 6, increasing the distance between them, so that it can be successfully sleeved outside the inner box body 1, maintaining the stability of the connection structure with the inner box body 1. After disassembly, the two side plates are adjusted relatively by the adjusting rods 6 to make the distance between them the same as the distance between the two side walls of the inner box body 1, so as to accurately form a communication structure of the same size as the inner box body 1, making the adjusted space structure only double in length, ensuring the efficiency and practicality of the overall space adjustment, and greatly meeting the demand for additional space use without making major changes to the original space. Anchor bolt holes 7 are provided at the corresponding positions on the bottom of the side plates 5 and the inner box body 1, so that the outer box body 3 can be firmly fixed to the ground through the anchor bolt holes 7 at the bottom after being connected to or disassembled from the inner box body 1, ensuring the stability of the connection structure between the whole house and the ground before and after the space adjustment of the house. The closing assembly includes a plurality of foldable and retractable blocking plates 8. The plurality of blocking plates 8 are rotationally connected end to end. The adjacent end parts of the plurality of blocking plates 8 can rotate relative to each other through a pin shaft or a hinge structure. When folded, the adjacent blocking plates 8 rotate to a parallel direction to form a structure with an increased thickness and a decreased length to close the end of the inner box body 1. When unfolded, the plurality of blocking plates 8 rotate 180 degrees to move to the same plane, forming a plate-like structure with a decreased thickness and an increased length, so as to better cooperate with the structure of the disassembled outer box body 3. The blocking plate 8 close to the end of the inner box body 1 is rotationally connected to the bottom of the inner box body 1 through a pin shaft or a hinge, so that it can not only achieve the blocking effect on one end of the inner box body 1, but also be disassembled and rotated to be used as the bottom plate of the adjacent outer box body 3. After the plurality of blocking plates 8 are folded, they are detachably connected to the side surface of the side plate 5 before disassembly, realizing the accurate closing of the end of the inner box body 1. After the plurality of blocking plates 8 are unfolded, the blocking plate 8 at the end far from the inner box body 1 is detachably connected to the side surface of the side plate 5 after disassembly in the vertical direction, realizing the closing effect on the end of the outer box body 3 after disassembly. The remaining blocking plates 8 are detachably connected to the bottom of the side plate 5 after disassembly in the horizontal direction and are used as the structure of the bottom of the outer box body 3 after disassembly. Thus, the closed structures at the bottom and ends of the outer box body 3 after disassembly do not need to be set additionally, and the original closing assembly at the end of the inner box body 1 is fully utilized to achieve this, and the full fixation and connection with the structure of the original inner box body 1 are maintained, realizing the stability of the overall structure after space adjustment, minimizing the need for additional accurate parts for expanding the space, and improving the convenience and practicality of the space adjustment of the house structure;

[0034] A method for spatial change of an assembled temporary house structure:

[0035] 1. After removing the top plate 4, side plates 5, and the closing assembly sleeved outside the inner box body 1, move them to one side of the end of the inner box body 1 where the closing assembly is located;

[0036] 2. Rotate the multiple plug plates 8 of the closing assembly so that the whole closing assembly forms a plate-like structure with an increased length and a decreased thickness after expansion, and is in the same plane as the bottom of the inner box body 1 relative to the end of the inner box body 1 after rotation, and is used as the bottom structure of the outer box body 3 after disassembly;

[0037] 3. Move the two side plates 5 after disassembly relative to each other under the adjustment of the adjusting rod 6 until the distance between the two side plates 5 is the same as the distance between the two side surfaces of the inner box body 1, and then move the top plate 4 and the side plates 5 above the expanded closing assembly as the top and side structures of the outer box body 3 to form a box structure communicating with one end of the inner box body 1;

[0038] 4. Use anchor bolts to pass through the anchor bolt holes at the bottom of the side plates 5 to fix the structure composed of the side plates 5 and the top plate 4 to the ground. The expanded closing assembly at the bottom is connected to the bottom of the side plates 5 or is pressed on the ground by the side plates 5 to realize the preliminary fixation of the structure of the outer box body 3 after disassembly;

[0039] 5. Rotate the plug plate 8 far from the end of the inner box body 1 to the vertical position and connect it to the side surface of the side plate 5, so as to realize the closing of the other end of the outer box body 3 after disassembly, double the length of the space of the overall structure of the house, and meet the needs of placing different personnel or equipment for use. When disassembling, operate according to the reverse steps above.

[0040] Preferably, fixing grooves 9 are symmetrically arranged on both sides of the inner box body 1 near the bottom. The fixing grooves 9 can be composed of channel steel fixed to the side surface of the inner box body 1 by welding or bolts. A bottom fixing plate 10 is welded or integrally formed at the bottom of the side plate 5. The bottom fixing plate 10 is slidably connected in the fixing groove 9. The anchor bolt holes 7 are arranged at the corresponding positions of the side wall of the fixing groove 9 and the bottom fixing plate 10. Such a structure makes the overall structure of the side plates 5 and the top plate 4 sleeved outside the inner box body 1 more convenient for disassembly and assembly. When installing, slide the whole structure composed of the side plates 5 and the top plate 4 until the anchor bolt holes 7 on the bottom fixing plate 10 are aligned with the anchor bolt holes 7 on the side wall of the fixing groove 9, and then use anchor bolts to pass through the anchor bolt holes 7 on both of them and fix them to the ground, so as to realize the synchronous fixation of the outer box body 3 and the inner box body 1 relative to the ground. The structure is simple, and at the same time, the relative fixation of the inner box body 1 and the outer box body 3 is realized, and the operation steps of fixation are further optimized. When disassembling, remove the anchor bolts and slide the outer box body 3 structure composed of the side plates 5 and the top plate 4 until it is disassembled from the inner box body 1 and moved to one side of the inner box body 1, so as to realize rapid disassembly and subsequent installation, greatly improving the convenience of disassembly and assembly of the outer box body 3 relative to the inner box body 1 and the stability of the relative structure.

[0041] Preferably, side fixing plates 11 are symmetrically welded or integrally formed and fixed on both sides of the plugging plate 8. Outer fixing holes 12 are provided on the side fixing plates 11. After the side plates 5 are disassembled, the outer fixing holes 12 are aligned with the anchor bolt holes 7 on the bottom fixing plate 10. Such a structure enables, when the side plates 5 are located above the bottom structure formed by the plugging plates 8 after disassembly, the anchor bolts to be passed through the anchor bolt holes 7 on the bottom fixing plate 10 and the outer fixing holes 12 on the side fixing plates 11 and then fixed to the ground, realizing the simultaneous fixing of the side and bottom of the outer box body 3 relative to the ground, thereby simplifying the operation steps for fixing the side and bottom of the outer box body 3 structure after disassembly and further improving the installation efficiency on the premise of ensuring stability.

[0042] Preferably, inner fixing holes 13 are provided on the side surfaces of the side plates 5. Before the side plates 5 are disassembled, the outer fixing holes 12 are aligned with the inner fixing holes 13. The side fixing plates 11 provided with the inner fixing holes 13 on the plugging plate 8 can not only be connected to the bottom fixing plate 10 with the anchor bolt holes 7 at the bottom of the side plates 5 after being unfolded, but also be connected and fixed to the inner fixing holes 13 provided on the side surfaces of the side plates 5 by bolts when the plugging plate 8 is folded and stored. The bolts are passed through the outer fixing holes 12 of the side fixing plates 11 on the upper sides of multiple folded plugging plates 8 and then thread-fixed to the inner fixing holes 13, thereby realizing the simultaneous closing of the end of the inner box body 1 and the fixing of the closed assembly composed of multiple folded plugging plates 8, enabling the structure of the closed assembly composed of multiple plugging plates 8 to simultaneously meet the fixing requirements when serving as the side and bottom structures, with a simple structure and convenient operation, greatly improving the structural stability and the disassembly and assembly efficiency.

[0043] Preferably, unfolding fixing holes 14 are further provided on the end plugging plates 8 away from the inner box body 1. After the side plates 5 are disassembled, the unfolding fixing holes 14 are aligned with the inner fixing holes 13. Since the distance between the two side plates 5 becomes smaller after unfolding, bolts are passed through the unfolding fixing holes 14 on the end plugging plates 8 and then connected to the inner fixing holes 13 on both side plates 5, enabling the unfolded end plugging plates 8 to be accurately fixed to the inner fixing holes 13 on the two side plates 5 with adjusted distances, ensuring the accurate closing of the end of the outer box body 3 after disassembly, ensuring the closing effect of the house structure after space adjustment, and ensuring the use experience of the house.

[0044] Preferably, convex plates 15 are symmetrically welded or integrally formed and fixed on both sides of the top plate 4. The adjusting rods 6 pass through the convex plates 15 and are connected to the side plates 5. The setting of the convex plates 15 provides support for the adjusting rods 6, ensuring the stability of the structure for the adjusting rods 6 to adjust the position of the side plates 5 and for the limiting structure.

[0045] Preferably, the adjusting rod 6 is threadedly connected to the convex plate 15. The end of the adjusting rod 6 passes through the convex plate 15 and is rotatably connected to the side plate 5 through a bearing. The arrangement of multiple adjusting rods 6 can drive the side plate 5 to move under the action of threaded connection while rotating, realizing the adjustment of the position of the side plate 5 relative to the top plate 4, and at the same time realizing the limiting effect of the relative position of the side plate 5 after adjustment, ensuring the stability of the structure of the outer box body 3 composed of the side plate 5 and the top plate 4.

[0046] Preferably, a plurality of guiding blocks 16 are welded or bolt-fixed to the top of the side plate 5, and a plurality of guiding grooves 17 are provided at the bottom of the top plate 4. The guiding blocks 16 are slidably connected in the guiding grooves 17. After the side plate 5 is disassembled, the guiding blocks 16 move to the ends of the guiding grooves 17. Such an arrangement makes the relative structure of the side plate 5 and the top plate 4 more stable when the side plate 5 slides relative to the top plate 4 to adjust the spacing. Moreover, after being disassembled and separated from the inner box body 1, the adjacent side structures formed by the two are kept firmly connected, not easily bent or misaligned, and the structure of the formed outer box body 3 is more firm. When the side plate 5 is disassembled and relatively moved and adjusted, when the adjusting rod 6 drives the side plate 5 to move, the guiding block 16 slides in the guiding groove 17 until the guiding block 16 contacts the end of the guiding groove 17 and the side plate 5 can no longer move. At this time, the spacing between the two side plates 5 is the same as the spacing between the two side surfaces of the inner box body 1, so that the adjustment of the spacing between the two side plates 5 is faster and more accurate, ensuring accurate connection with the inner box body 1.

[0047] Preferably, both the guiding block 16 and the guiding groove 17 are T-shaped for mating use. The T-shaped structure ensures that the side plate 5 slides horizontally relative to the top plate 4 while the relative position in the vertical structure does not change, ensuring the stability of the structure of the formed outer box body 3.

[0048] Preferably, the side surfaces of the inner box body 1 in a rectangular shape are all detachably connected. Such a structure makes the overall structure of the inner box body 1 an assembled structure fixed by bolts, enabling it to be quickly disassembled and assembled for use, and can be repeatedly assembled at different positions after use, reducing the construction cost of the temporary housing structure, improving the recycling and reuse of parts, and making the housing structure more environmentally friendly.

[0049] Working principle: The structure of the present invention includes a rectangular inner box body 1. One side of the inner box body 1 is blocked by a door panel 2, and a closing component is arranged on the other side to realize the relative closure of the overall structure of the house and ensure the normal use of the house structure. A detachable outer box body 3 is sleeved outside the inner box body 1. After the outer box body 3 is disassembled, a same-size structure communicating with the inner box body 1 is formed, doubling the overall space of the temporary house, so as to quickly meet the sudden increase in the number of people or the placement of equipment, etc., greatly improving the effect of the temporary house in dealing with emergencies. Moreover, the whole outer box body 3 is sleeved outside the inner box body 1 during normal use, without occupying extra space, only increasing the thickness of the house, ensuring the normal use of the temporary house, greatly expanding the application range of the temporary house and improving the adaptability to different environments; the outer box body 3 includes a top plate 4 and symmetrically arranged side plates 5. The two side plates 5 are symmetrically and slidably connected to the bottom of the top plate 4. An adjusting rod 6 is used to adjust the position of the side plates 5 relative to the top plate 4, so that the side plates 5 can be sleeved on the side of the inner box body 1 during normal use. When the space is adjusted, the two side plates 5 move relative to each other under the action of the adjusting rod 6 until the distance between the two side plates 5 is the same as the distance between the two side surfaces of the inner box body 1, so that the disassembled outer box body 3 and the inner box body 1 maintain an accurate same-size structure, doubling the internal space of the adjusted temporary house directly on the original basis without changing the objects in the original inner box body 1, making the space adjustment more efficient and convenient. Anchor bolt holes 7 are provided at the corresponding positions on the bottom of the side plates 5 and on the inner box body 1. Such a structure enables the overall house structure to be fixed on the ground under the action of the anchor bolts passing through the anchor bolt holes 7 before and after the space adjustment, making the disassembly and assembly steps more concise and efficient and the space adjustment more convenient and efficient; the closing component includes a plurality of foldable and retractable blocking plates 8. The plurality of blocking plates 8 are rotatably connected end to end, and the blocking plate 8 at the end close to the inner box body 1 is rotatably connected to the bottom of the inner box body 1. After the plurality of blocking plates 8 are folded, they are detachably connected to the side surface of the side plate 5 before disassembly. After the plurality of blocking plates 8 are unfolded, the blocking plate 8 at the end far from the inner box body 1 is detachably connected to the side surface of the side plate 5 vertically, and the remaining blocking plates 8 are detachably connected to the bottom of the side plate 5 horizontally. Such a structure enables one end of the outer box body 3 after the space adjustment to communicate with the inner box body 1. The closing component is rotated to the horizontal direction to serve as the bottom structure of the outer box body 3, and the blocking plate 8 at the end far from the inner box body 1 is rotated to the vertical direction to serve as the side structure of the outer box body 3, thereby realizing the through and stable connection of the whole outer box body 3 and the inner box body 1. By using the structure of the original house side as the source of space adjustment, the extra space occupancy rate of the outer box body 3 is reduced, ensuring the stability of the house structure before and after the space adjustment, and greatly improving the convenience and practicality of the space adjustment.
