Description

Technical Field

[0001] This application relates to the field of exhaust gas detection, and in particular to a prefabricated house and its construction method. Background Technology

[0002] Prefabricated buildings are a new type of building production method that integrates various business areas such as R&D design, production and manufacturing, and on-site assembly, with standardized design, factory production, assembly construction, integrated decoration and information management as its characteristics, and the production of building products. It achieves energy conservation, environmental protection and full life cycle value maximization.

[0003] For example, patent CN113833121A discloses a prefabricated house and its construction method, which allows for the direct assembly of the base, top, and supporting panels into a closed housing space at the desired location. The house is then secured by inserting ground pins into the ground.

[0004] If the aforementioned prefabricated buildings are to be used as temporary structures such as pop-up stores, they must be installed indoors or in locations where it is difficult to insert the ground bolts, making it impossible to securely fix the building and thus limiting the applicability of the aforementioned prefabricated buildings. Summary of the Invention

[0005] In order to expand the application scope of prefabricated houses, On the one hand, the prefabricated house provided in this application adopts the following technical solution: A prefabricated house includes a main building and a base for supporting the main building. The base has a receiving groove on its bottom surface, and a support plate is slidably connected within the receiving groove in a vertical direction. A driving assembly for sliding the support plate is provided between the bottom surface of the receiving groove and the support plate. A friction pad for increasing friction is provided on the side of the support plate facing away from the driving assembly. A through groove for connecting the side wall of the base is provided in a horizontal direction on the side wall of the receiving groove, and an anchoring lug is slidably connected within the through groove in a horizontal direction. When the friction pad abuts against the installation platform, the anchoring lug is concealed within the through groove. A linkage is provided between the support plate and the anchoring lug; when the support plate moves upward, the linkage drives the anchoring lug to move outward.

[0006] By adopting the above technical solutions, different states of the support plate and anchoring lugs can be selected according to different installation surfaces, so as to select different connection methods between the base and the installation surface. This allows prefabricated houses to be adapted to different installation surfaces, such as soil surfaces, indoor surfaces, and marble surfaces in plazas, further expanding the application scope of prefabricated houses.

[0007] Optionally, the peripheral wall of the receiving plate completely abuts against the inner wall of the receiving groove, and the driving assembly includes an airbag, which is fixedly connected to the bottom surface of the receiving groove and the receiving plate; when the airbag is inflated, the thickness of the airbag in the vertical direction increases, and when the airbag is deflated, the thickness of the airbag in the vertical direction decreases.

[0008] Optionally, the airbag includes a plurality of airbag units and an air tube for connecting adjacent airbag units. The airbag units are evenly distributed in the receiving groove, and the two ends of the airbag units abut against the two opposite sidewalls of the receiving groove.

[0009] Optionally, the linkage includes an active linkage rod fixedly connected to the receiving plate in the vertical direction and a driven linkage rod fixedly connected to the anchoring lug in the horizontal direction. The upper end of the active linkage rod is inclined to form a first guide surface, and the end of the driven linkage rod away from the anchoring lug is inclined to form a second guide surface, with the second guide surface abutting against the first guide surface. When the active linkage rod moves upward, it pushes the driven linkage rod to move outward from the receiving groove.

[0010] Optionally, the linkage includes a driving rod fixedly connected to the support plate in the vertical direction, a driven rod fixedly connected to the anchoring lug in the horizontal direction, and a linkage rod located between the driving rod and the driven rod, with both ends of the linkage rod rotatably connected to the driving rod and the driven rod, respectively.

[0011] Optionally, the receiving plate is provided with an anchoring spike that passes through the friction pad, the anchoring spike being slidably connected to the receiving plate, and the receiving plate is provided with a power component for driving the anchoring spike to move in the vertical direction.

[0012] Optionally, the power component includes a drive rack, a transmission gear, and a linkage rack. The drive rack is vertically arranged and fixedly connected to the receiving plate. The transmission gear is rotatably connected to the base and meshes with the drive rack. The linkage rack is vertically arranged and fixedly connected in parallel to the side wall of the anchor spike. The linkage rack meshes with the transmission gear. The linkage rack and the drive rack are distributed on both sides of the transmission gear.

[0013] Optionally, several anchor pins are provided along the axial direction of the transmission gear, and one anchor pin corresponds to one active rack and one linkage rack; at least one transmission gear is provided between adjacent airbag units.

[0014] Optionally, the base has an installation groove for embedding the building body, which is embedded in the installation groove and detachably connected to the base.

[0015] On the other hand, the construction method for prefabricated houses provided in this application adopts the following technical solution: A construction method for prefabricated houses includes the following steps. S1. When not installed, the anchor lug is located inside the base and the lower end face of the friction pad is located inside the receiving groove. If the house needs to be installed outdoors on the ground where the anchor rod can be easily inserted, proceed to step S2. If the house needs to be installed indoors or on the ground where the anchor rod cannot be easily inserted, proceed to step S3. S2. The airbag is pumped out by the air pump, causing the support plate to move upward and the anchoring lug to move outward and protrude from the base. The anchor rod is passed through the anchoring lug to make the base firmly installed on the surface to be installed. At the same time as the support plate moves upward, the anchor pierces through the support plate and friction pad and is inserted into the surface to be installed, so that the base is firmly installed on the surface to be installed. Then proceed to step S4. S3. Inflate the airbag with an air pump to make the receiving plate move downward until the friction pad abuts against the surface to be installed and exerts downward pressure on the surface to be installed, so that the base is firmly installed on the surface to be installed; at the same time, the anchoring lug is hidden inside the base, and then proceed to step S4. S4. Embed the main building body into the mounting groove of the base and fix the main building body to the base.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. Prefabricated houses can be adapted to different installation surfaces, thus expanding their applicability. 2. Prefabricated houses are stably connected to the installation surface and are easy to install; 3.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0022] Example 1 This application discloses a prefabricated house. (Refer to...) Figure 1 and Figure 2 As shown, a prefabricated house includes a main building 1 and a base 2 for supporting the main building 1. The base 2 has an installation groove 3 for the main building 1 to be embedded in, and the main building 1 is embedded in the installation groove 3 and detachably connected to the base 2. The main building 1 is generally fixed to the base 2 by screws, nuts, mounting lugs, etc.

[0023] Reference Figure 3 and Figure 4 As shown, to broaden the applicability of prefabricated houses, a receiving groove 4 is provided on the bottom surface of the base 2. A support plate 5 is slidably connected in the vertical direction within the receiving groove 4, and the periphery of the support plate 5 completely abuts against the inner wall of the receiving groove 4. A friction pad 6 is provided on the side of the support plate 5 facing away from the driving component to increase friction. The friction pad 6 is made of an elastic material such as rubber.

[0024] Reference Figure 3 and Figure 4 As shown, a driving assembly for sliding the receiving plate 5 is provided between the bottom surface of the receiving groove 4 and the receiving plate 5. The driving assembly includes an airbag, which is fixedly connected to the bottom surface of the receiving groove 4 and the receiving plate 5. When the airbag is inflated, its thickness in the vertical direction increases; when the airbag is deflated, its thickness in the vertical direction decreases. The airbag includes several airbag units 7 and vent pipes 8 for connecting adjacent airbag units 7. The airbag units 7 are evenly distributed in the receiving groove 4, and both ends of the airbag units 7 abut against two opposite sidewalls of the receiving groove 4. One of the airbag units 7 is provided with an external connecting pipe 9, which is equipped with an opening and closing valve. The external connecting pipe 9 is connected to an external air pump to realize the inflation and deflation of the airbag.

[0025] When the house needs to be installed on a surface that cannot be anchored, such as a square or indoors, the airbag is inflated by an air pump to increase its thickness. The support plate 5 is pushed downward by the airbag until the friction pad 6 comes into contact with the surface to be installed and exerts downward pressure on the surface, so that the base 2 is firmly installed on the surface to be installed and cannot be pushed.

[0026] Reference Figure 3 and Figure 4 As shown, the side wall of the receiving groove 4 has a horizontally oriented through groove 10 for connecting to the side wall of the base 2. An anchoring lug 11 is slidably connected horizontally within the through groove 10, and the anchoring lug 11 has a through hole. There are several through grooves 10, and in this embodiment, there are four located at the four corners of the receiving groove 4. Each through groove 10 contains only one anchoring lug 11. When the friction pad 6 abuts against the installation platform, the anchoring lug 11 is hidden within the through groove 10, so that the anchoring lug 11 does not affect the appearance of the prefabricated house and will not trip pedestrians. If the base 2 needs to be installed on a soil-like surface, the airbag needs to be inflated by an air pump to reduce the thickness of the airbag. The receiving plate 5 is pushed upward by the airbag, allowing the friction pad 6 to enter the receiving groove 4. Then, the anchoring lug 11 is pulled outward until the through hole is exposed, facilitating the installation of the anchor rod.

[0027] Reference Figure 3 and Figure 4 As shown, to facilitate adjustment of the position of the anchoring lug 11 relative to the base 2, a linkage is provided between the receiving plate 5 and the anchoring lug 11. The linkage includes a driving rod 12 fixedly connected vertically to the receiving plate 5, a driven rod 13 fixedly connected horizontally to the anchoring lug 11, and a connecting rod 14 located between the driving rod 12 and the driven rod 13. The two ends of the connecting rod 14 are rotatably connected to the driving rod 12 and the driven rod 13, respectively. When the receiving plate 5 moves upward, the driving rod 12 moves upward, causing the connecting rod 14 to rotate. The connecting rod 14 pushes the driven rod 13 outward, thereby causing the anchoring lug 11 to move outward, making operation convenient. Similarly, when the receiving plate 5 moves downward, it can cause the anchoring lug 11 to move into the receiving groove 4, facilitating the storage of the anchoring lug 11.

[0028] Reference Figure 3 and Figure 4As shown, to ensure a more stable connection between the base 2 and the soil-like installation surface, the receiving plate 5 is equipped with an anchor spike 15 that passes through the friction pad 6. The anchor spike 15 is slidably connected to the receiving plate 5 in the vertical direction. The receiving plate 5 is equipped with a power component for driving the anchor spike 15 to move vertically. The power component includes a drive rack 16, a transmission gear 17, and a linkage rack 18. The drive rack 16 is vertically positioned and fixedly connected to the receiving plate 5. The transmission gear 17 is rotatably connected to the base 2 and meshes with the drive rack 16. The linkage rack 18 is vertically positioned and parallel to and fixedly connected to the side wall of the anchor spike 15. The linkage rack 18 meshes with the transmission gear 17. The linkage rack 18 and the drive rack 16 are located on both sides of the transmission gear 17. When the receiving plate 5 moves upward, the drive rack 16 moves upward, causing the transmission gear 17 to rotate. The transmission gear 17 then causes the linkage rack 18 to move downward, thereby causing the anchor spike 15 to move downward and anchor into the installation surface.

[0029] Reference Figure 3 and Figure 4 As shown, to ensure a more stable connection between the base 2 and the mounting surface, several anchor spikes 15 are provided along the axial direction of the transmission gear 17, with each anchor spike 15 corresponding to a driving rack 16 and a linkage rack 18. At least one transmission gear 17 is provided between adjacent airbag units 7. To improve the synchronization rate of the anchor spikes 15, a synchronizing rod 21 is provided on each anchor spike 15 corresponding to the same transmission gear 17. The synchronizing rod 21 is fixedly connected to the upper end of all its corresponding anchor spikes 15. The synchronizing rod 21 slides against the side wall of the receiving groove 4, further ensuring that the anchor spikes 15 can only move vertically under the drive of the transmission gear 17.

[0030] The construction method for this prefabricated house includes the following steps. S1. When not installed, the anchor lug 11 is located inside the base 2, and the lower end face of the friction pad 6 is located inside the receiving groove 4. If the house needs to be installed outdoors on the ground where it is easy to insert the anchor rod, proceed to step S2. If the house needs to be installed indoors or on the ground where it is not easy to insert the anchor rod, proceed to step S3. S2. The airbag is evacuated by the air pump, causing the supporting plate 5 to move upward. The anchoring spike 15 passes through the supporting plate 5 and the friction pad 6 and is inserted into the plane to be installed, so that the base 2 is stably installed on the plane to be installed. At the same time, the anchoring lug 11 moves outward and protrudes outside the base 2. The anchor rod passes through the anchoring lug 11 so that the base 2 is stably installed on the plane to be installed. Then proceed to step S4. S3. Inflate the airbag with an air pump to make the receiving plate 5 move downward until the friction pad 6 abuts against the surface to be installed and has a downward pressure on the surface to be installed, so that the base 2 is firmly installed on the surface to be installed; at the same time, the anchoring lug 11 is hidden inside the base 2, and then proceed to step S4. S4. Embed the building body 1 into the mounting groove 3 of the base 2, and fix the building body 1 to the base 2.

[0031] Example 2 The difference between Example 2 and Example 1 lies in the different linkage components. For example... Figure 5 As shown, the linkage includes an active linkage rod 22 fixedly connected to the receiving plate 5 in the vertical direction and a driven linkage rod 23 fixedly connected to the anchoring lug 11 in the horizontal direction. The upper end of the active linkage rod 22 is inclined to form a first guide surface 19, and the end of the driven linkage rod 23 away from the anchoring lug 11 is inclined to form a second guide surface 20. The second guide surface 20 abuts against the first guide surface 19. When the active linkage rod 22 moves upward, the active linkage rod 23 pushes the driven linkage rod 24 to move outward toward the receiving groove 4.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
