Description

Technical Field

[0001] The present application relates to the technical field of prefabricated buildings, and in particular to a prefabricated house and a construction method thereof. Background Art

[0002] Prefabricated buildings are structures that shift much of the traditional on-site construction work to factories. Components and accessories are manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connections. Prefabricated buildings primarily include prefabricated concrete structures, steel structures, and modern wood structures.

[0003] The existing construction method of prefabricated houses is to hoist the prefabricated wall panels onto the floor slab, then perform grouting to seal the gaps, then tie steel bars in the gaps between the two prefabricated wall panels, set up formwork and pour concrete in situ to achieve the connection between the two prefabricated wall panels.

[0004] However, when the building space is large and the wall surface of the entire wall is too long, it is necessary to assemble multiple prefabricated wall panels and perform multiple steel bar binding and cast-in-place operations, which is relatively cumbersome and greatly prolongs the construction period. Summary of the Invention

[0005] In order to effectively shorten the construction period, the present application provides a prefabricated house and a construction method thereof.

[0006] On the one hand, the purpose of this application is to provide a prefabricated house, which adopts the following technical solutions:

[0007] An assembled house includes a top frame, a bottom frame and a plurality of columns located between the top frame and the bottom frame, an assembled wall is arranged between the columns, and the assembled wall includes a plurality of prefabricated wall panels located between the columns and at least two connecting rib tubes arranged vertically, the side surfaces of two adjacent prefabricated wall panels are abutted, the side surfaces of the prefabricated wall panels are provided with connecting holes for inserting the connecting rib tubes, and the connecting rib tubes are provided with limiting components for limiting the ends of the connecting rib tubes within the connecting holes.

[0008] By adopting the above technical solution, a group of prefabricated wall panels can be quickly connected together by using the connection rib tube, and the end of the connection rib tube is restricted in the connection hole by the restriction component, making the insertion of the connection rib tube easier, so that the connection between the connection rib tube and the connection hole is more stable, thereby making the connection between the prefabricated wall panels more stable, thereby improving the connection strength between the prefabricated wall panels, which can shorten the construction period.

[0009] Optionally, the limiting assembly includes a sliding groove and a limiting block, the sliding groove is opened on the side of the connecting rib tube, the limiting block is slidably connected in the sliding groove, and a clamping ring is fixedly connected to the hole wall of the connecting hole and is clamped with the end of the limiting block; a clamping spring is provided in the sliding groove, one end of the clamping spring is fixed on the groove wall of the sliding groove, and the other end of the clamping spring is fixed on the limiting block.

[0010] By adopting the above technical solution, when two adjacent prefabricated wall panels are assembled and fitted together, the two ends of the connecting rib tube will be inserted into the connecting holes of the two prefabricated wall panels; the end of the limiting block can be made to protrude from the side of the connecting rib tube through the clamping spring, so that the side of the limiting block abuts against the inner side of the clamping ring, thereby limiting the end of the connecting rib tube in the connecting hole.

[0011] Optionally, two sliding cylinders are connected to the outer surface of the connecting rib tube, and the two sliding cylinders respectively correspond to the limiting blocks at both ends of the connecting rib tube, and the ends of the limiting blocks can abut against the inner wall of the sliding cylinder; the outer diameter of the sliding cylinder is equal to the aperture of the connecting hole.

[0012] By adopting the above technical solution, when the end of the connecting rib tube is inserted into the connecting hole, the two sliding cylinders will respectively abut the outer side surfaces of the two clamping rings, so that the two sliding cylinders on the connecting rib tube are close to each other, thereby causing the sliding cylinder and the limiting block to be misaligned, making it easier for the end of the limiting block to protrude from the side surface of the connecting rib tube and then be clamped with the clamping ring. This makes it easier to pass the connecting rib tube, and the limiting block can be easily located on the inner side surface of the clamping ring.

[0013] Optionally, a sliding hole is provided in the connecting rib tube, a pull rope is slidingly connected in the sliding hole, one end of the pull rope is fixed on the limiting block, and the other end of the pull rope is fixedly connected to a pull ring; an accommodating groove for accommodating the pull ring is provided on the end face of the prefabricated wall panel.

[0014] By adopting the above technical solution, pulling the pull ring outward will cause the end of the limiting block to retract into the sliding groove, so that the end of the connecting rib tube can be pulled out from the connecting hole of the prefabricated wall panel, thereby facilitating the disassembly and reuse of the assembled wall.

[0015] Optionally, a connecting piece is fixedly connected to the side of the column, and the connecting piece is connected to the prefabricated wall through fixing bolts.

[0016] By adopting the above technical solution, the connecting parts and the fixing bolts cooperate with each other, making it easier to fix the assembled wall on the columns, thereby making the structural strength of the entire assembled house higher.

[0017] Optionally, a shock-absorbing mechanism is provided between the column and the top frame, and the shock-absorbing mechanism includes a sliding seat and an upper support. A sliding groove is provided on the upper surface of the column, and the bottom of the sliding seat is slidingly connected to the sliding groove; a spherical block is provided on the surface of the upper support facing the sliding seat, and a spherical groove matching the spherical block is provided on the sliding seat, and the upper support is fixedly connected to the top frame; a shock-absorbing member is provided between the sliding seat and the groove wall of the displacement groove.

[0018] By adopting the above technical solution, when the prefabricated house is vibrated by external force, the spherical block cooperates with the spherical groove to allow the top frame to deflect to a certain extent on the sliding seat, so that the force transmitted from the top frame to the column can be dispersed into horizontal and vertical forces through the spherical block and the spherical groove, so as to push the sliding seat to move horizontally in the sliding groove; and then the shock-absorbing component can reduce the amplitude of the horizontal movement of the sliding seat, thereby improving the seismic performance of the prefabricated house.

[0019] Optionally, polytetrafluoroethylene plates are provided between the spherical block and the spherical groove and between the groove bottom of the sliding groove and the sliding seat.

[0020] By adopting the above technical solution, the friction coefficient of the polytetrafluoroethylene plate is low, and the top frame encounters less resistance when deflecting on the sliding seat; at the same time, the sliding seat encounters less resistance when moving horizontally in the sliding groove, thereby improving the seismic performance of the prefabricated house.

[0021] Optionally, a mounting groove for inserting the upper support is provided on the surface of the top frame, a positioning groove is provided on the prefabricated wall surface, and a positioning block that is plugged into the positioning groove is fixedly connected to the top frame.

[0022] By adopting the above technical solution, the mounting groove enables the top frame to be fixed on the shock-absorbing mechanism more conveniently; the positioning block and the positioning groove cooperate to limit the horizontal direction of two adjacent prefabricated wall panels, thereby improving the connection strength of the assembled wall.

[0024] By adopting the above technical solution, the buffer plate and the buffer spring cooperate to disperse the force transmitted from the top frame to the prefabricated wall into horizontal and vertical forces, so as to push the buffer plate to move vertically in the positioning groove, thereby reducing the amplitude of the vertical movement of the top frame, thereby improving the seismic performance of the prefabricated house.

[0025] On the other hand, the present application provides a construction method for a prefabricated house, which adopts the following technical solution:

[0026] A construction method for a prefabricated house comprises the following steps:

[0027] Move the prefabricated wall panels onto the bottom frame so that each prefabricated wall panel is arranged side by side between two adjacent columns;

[0028] Insert the two ends of the connecting rib tube into the connecting holes of two adjacent prefabricated wall panels respectively, then push one of the prefabricated wall panels so that the sides of the two adjacent prefabricated wall panels are aligned, and then use the limiting component to limit the end of the connecting rib tube in the connecting hole;

[0029] The prefabricated wall panels at the edges are fixedly connected to the columns, and the top frame is then fixedly connected to the top of the columns.

[0030] By adopting the above technical solution, a group of prefabricated wall panels can be quickly connected together by using the connection rib tube, and the end of the connection rib tube is restricted in the connection hole by the restriction component, making the insertion of the connection rib tube easier, so that the connection between the connection rib tube and the connection hole is more stable, thereby making the connection between the prefabricated wall panels more stable, thereby improving the connection strength between the prefabricated wall panels, which can shorten the construction period.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. By using the connecting rib tube, a group of prefabricated wall panels can be quickly connected together.

[0033] 2. When the end of the connecting rib tube is inserted into the connecting hole, the two sliding cylinders will respectively abut the outer sides of the two clamping rings, so that the two sliding cylinders on the connecting rib tube are close to each other, thereby causing the sliding cylinder and the limiting block to be misaligned, making it easier for the end of the limiting block to protrude from the side of the connecting rib tube and then be clamped with the clamping ring. This makes it easier to pass the connecting rib tube and the limiting block can be easily located on the inner side of the clamping ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-4 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0040] The embodiment of the present application discloses a prefabricated house. Figure 1 The prefabricated house includes a top frame 1, a bottom frame 2 and a plurality of columns 3 located between the top frame 1 and the bottom frame 2, wherein the top frame 1, the bottom frame 2 and the columns 3 are all pre-cast with reinforced concrete, the top frame 1 and the bottom frame 2 are arranged in a horizontal direction, the columns 3 are arranged in a vertical direction, and the bottom ends of the columns 3 are fixedly connected to the bottom frame 2, and the top frame 1 is fixedly connected to the top ends of the columns 3.

[0041] Reference Figure 1 and Figure 2 To improve the seismic performance of the prefabricated house, a shock-absorbing mechanism 13 is installed between the columns 3 and the top frame 1. This mechanism includes a sliding seat 131 and an upper support 132. The upper surface of the column 3 is provided with a sliding groove 133, into which the bottom of the sliding seat 131 slides. The lower surface of the top frame 1 is provided with a mounting groove 15, into which the top of the upper support 132 is inserted, thereby securing the upper support 132 to the top frame 1. The sliding groove 133 can be reserved when the column 3 is cast, and the mounting groove 15 can be reserved when the top frame 1 is cast. The sliding groove 133 and the mounting groove 15 facilitate the assembly of the shock-absorbing mechanism 13 between the column 3 and the top frame 1.

[0042] Reference Figure 1 and Figure 2 To improve the seismic resistance of the prefabricated house, a spherical block 134 is integrally formed on the surface of the upper support 132 facing the sliding seat 131. A spherical groove 135 is provided on the sliding seat 131, which mates with the spherical block 134. A shock absorber 136 is installed between the sliding seat 131 and the wall of the displacement groove. The sliding seat 131, spherical block 134, and upper support 132 are all made of stainless steel. The cross-sections of the sliding seat 131 and upper support 132 are all square. The spherical groove 135 is provided on the upper surface of the sliding seat 131. The shock absorber 136 is a leaf spring. There are four sets of leaf springs, one on each of the four sides of the sliding seat 131. The middle of the leaf spring is bolted to the side of the sliding seat 131, and the two ends of the leaf spring abut against the wall of the sliding groove 133.

[0043] It should be noted that when the prefabricated house is vibrated by external force, the spherical block 134 cooperates with the spherical groove 135 to allow the top frame 1 to deflect to a certain extent on the sliding seat 131, so that the force transmitted from the top frame 1 to the column 3 can be dispersed into horizontal and vertical forces through the spherical block 134 and the spherical groove 135, so as to push the sliding seat 131 to move horizontally in the sliding groove 133; and then the shock absorber 136 can reduce the amplitude of the horizontal movement of the sliding seat 131, thereby improving the seismic performance of the prefabricated house.

[0044] Reference Figure 1 and Figure 2 To reduce the resistance encountered by the upper support 132 during deflection, a polytetrafluoroethylene (PTFE) plate 14 is installed between the spherical block 134 and the spherical groove 135, and between the bottom of the sliding groove 133 and the sliding seat 131. The polytetrafluoroethylene (PTFE) plate 14 between the spherical block 134 and the spherical groove 135 is an arc-shaped plate, and the bottom of the spherical groove 135 defines a first recessed groove (not labeled in the figure) for securing the arc-shaped plate. The polytetrafluoroethylene (PTFE) plate 14 between the bottom of the sliding groove 133 and the sliding seat 131 is a rectangular plate, and the bottom surface of the sliding seat 131 defines a second recessed groove (not labeled in the figure) for securing the rectangular plate. Due to the low friction coefficient of the PTFE plate 14, the top frame 1 encounters less resistance when deflecting on the sliding seat 131. Simultaneously, the sliding seat 131 also encounters less resistance when moving horizontally within the sliding groove 133, thereby improving the seismic resistance of the prefabricated house.

[0045] Reference Figure 1 and Figure 2To shorten the construction period of the house, an assembly wall 4 is installed between two adjacent columns 3. Connectors 12 are bolted to the sides of the columns 3. Connectors 12 are connected to the assembly wall 4 via fixing bolts. Connectors 12 are connecting plates with circular holes for the fixing bolts to pass through. The end faces of the assembly wall 4 have threaded holes that mate with the fixing bolts. This facilitates the fixing of the assembly wall 4 to the columns 3, thereby enhancing the structural strength of the entire prefabricated house.

[0046] Reference Figure 1 and Figure 2 To enhance the connection strength of the assembled wall 4, positioning grooves 16 are provided on the assembled wall 4, and positioning blocks 17 are fixedly connected to the top frame 1. The positioning blocks 17 engage with the positioning grooves 16. The assembled wall 4 includes a plurality of prefabricated wall panels 41 positioned between the columns 3, with positioning grooves 16 defined in the prefabricated wall panels 41. The prefabricated wall panels 41 are precast with reinforced concrete, and the positioning grooves 16 can be reserved when the prefabricated wall panels 41 are cast. The positioning blocks 17 are integrally cast with the top frame 1. The positioning blocks 17 cooperate with the positioning grooves 16 to horizontally limit the position of two adjacent prefabricated wall panels 41, thereby enhancing the connection strength of the assembled wall 4.

[0047] Reference Figure 1 and Figure 2 To improve the seismic performance of the prefabricated house, a buffer plate 18 is slidably connected to the positioning groove 16. A buffer spring 19 is installed in the positioning groove 16. One end of the buffer spring 19 is welded to the buffer plate 18, and the other end of the buffer spring 19 is welded to the bottom of the positioning groove 16. The buffer plate 18 is made of stainless steel. The buffer plate 18 and the buffer spring 19 cooperate to disperse the force transmitted from the top frame 1 to the prefabricated wall into horizontal and vertical forces, thereby pushing the buffer plate 18 to move vertically within the positioning groove 16, thereby reducing the amplitude of the vertical movement of the top frame 1, thereby improving the seismic performance of the prefabricated house.

[0048] Reference Figure 3 and Figure 4 To enhance the connection strength between prefabricated wall panels 41, the sides of two adjacent prefabricated wall panels 41 are aligned. Connection holes 5 are provided on the sides of the prefabricated wall panels 41, into which connection rib tubes 42 are inserted. Two adjacent prefabricated wall panels 41 have at least two connection rib tubes 42 arranged vertically. These connection rib tubes 42 allow a group of prefabricated wall panels 41 to be quickly connected.

[0049] Reference Figure 3 and Figure 4To ensure a more stable connection between the prefabricated wall panels 41, a limiting assembly 6 is installed on the connecting rib tube 42. The limiting assembly 6 is used to limit the end of the connecting rib tube 42 within the connecting hole 5. The limiting assembly 6 includes a sliding groove 61 and a limiting block 62. The sliding groove 61 is provided on the side of the connecting rib tube 42. The limiting block 62 is slidably connected within the sliding groove 61. A clamping ring 63 is fixedly connected to the wall of the connecting hole 5. The clamping ring 63 can be clamped and matched with the end of the limiting block 62. A clamping spring 64 is installed in the sliding groove 61. One end of the clamping spring 64 is fixed to the groove wall of the sliding groove 61 by welding, and the other end of the clamping spring 64 is fixed to the limiting block 62 by welding.

[0050] It should be noted that when two adjacent prefabricated wall panels 41 are assembled and fitted together, the two ends of the connecting rib tube 42 will be inserted into the connecting holes 5 of the two prefabricated wall panels 41; the clamping spring 64 can allow the end of the limiting block 62 to protrude from the side of the connecting rib tube 42, so that the side of the limiting block 62 abuts against the inner side of the clamping ring 63, thereby limiting the end of the connecting rib tube 42 in the connecting hole 5, so that the connection between the connecting rib tube 42 and the connecting hole 5 is more stable, thereby making the connection between the prefabricated wall panels 41 more stable, thereby improving the connection strength between the prefabricated wall panels 41.

[0051] Reference Figure 3 and Figure 4 To facilitate the insertion of the connecting rib tube 42, two sliding cylinders 7 are connected to the outer surface of the connecting rib tube 42. These sliding cylinders 7 correspond to the limiting blocks 62 at either end of the connecting rib tube 42, and the ends of the limiting blocks 62 can abut the inner wall of the sliding cylinder 7. The outer diameter of the sliding cylinder 7 is equal to the diameter of the connecting hole 5. A return spring 20 is connected to the outer surface of the connecting rib tube 42. One end of the return spring 20 is welded to one sliding cylinder 7, and the other end is welded to the other sliding cylinder 7.

[0052] It should be noted that when the end of the connecting rib tube 42 is inserted into the connecting hole 5, the two sliding cylinders 7 will respectively abut the outer side surfaces of the two clamping rings 63, so that the two sliding cylinders 7 on the connecting rib tube 42 are close to each other, thereby causing the sliding cylinder 7 and the limiting block 62 to be misaligned, making it easier for the end of the limiting block 62 to protrude from the side surface of the connecting rib tube 42 and be clamped with the clamping ring 63. This makes it easier to pass the connecting rib tube 42, and the limiting block 62 can be easily located on the inner side surface of the clamping ring 63.

[0053] Reference Figure 3 and Figure 4To facilitate disassembly and reuse of the assembled wall 4, a sliding hole 8 is defined within the connecting rib tube 42. A pull cord 9 is slidably connected within the sliding hole 8. One end of the pull cord 9 is secured to the limiting block 62, and the other end of the pull cord 9 is fixedly connected to a pull ring 10. A receiving groove 11 for the pull ring 10 is defined on the end surface of the prefabricated wall panel 41. Pulling the pull ring 10 outward retracts the end of the limiting block 62 into the sliding groove 61, allowing the end of the connecting rib tube 42 to be removed from the connecting hole 5 of the prefabricated wall panel 41, thereby facilitating disassembly and reuse of the assembled wall 4.

[0054] The implementation principle of an assembled house in an embodiment of the present application is: by using the insertion of the connecting rib tube 42, a group of prefabricated wall panels 41 can be quickly connected together, and the end of the connecting rib tube 42 is restricted in the connecting hole 5 by the limiting component 6, so that the insertion of the connecting rib tube 42 is relatively easy, so that the connection between the connecting rib tube 42 and the connecting hole 5 is more stable, thereby making the connection between the prefabricated wall panels 41 more stable, thereby improving the connection strength between the prefabricated wall panels 41, which can shorten the construction period.

[0055] The present application also discloses a method for constructing a prefabricated house, which includes the following steps:

[0056] Step S1: Move the prefabricated wall panels 41 onto the bottom frame 2 so that each prefabricated wall panel 41 is arranged side by side between two adjacent columns 3.

[0057] Step S2: insert the two ends of the connecting rib tube 42 into the connecting holes 5 of the two adjacent prefabricated wall panels 41 respectively, then push one of the prefabricated wall panels 41 so that the sides of the two adjacent prefabricated wall panels 41 are in contact with each other, and then use the limiting component 6 to limit the end of the connecting rib tube 42 in the connecting hole 5.

[0058] Step S3: Fix the edge prefabricated wall panels 41 to the columns 3 , and then fix the top frame 1 to the top of the columns 3 .

[0059] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Unless otherwise specified, any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features. Therefore, any equivalent changes based on the structure, shape, and principle of this application shall be included in the scope of protection of this application.
