Description

Technical Field

[0001] The invention relates to the technical field of house construction, in particular to a modular integrated house and a construction method thereof. Background Art

[0002] As the urbanization process gradually accelerates, people's demand for housing construction is increasing. The traditional construction method has a long construction period, high resource consumption, and serious environmental pollution problems. It is difficult to meet the housing construction needs of rapid urbanization. At the same time, with the continuous increase in labor costs, the cost of housing construction is also getting higher and higher.

[0003] Prefabricated buildings refer to buildings assembled with prefabricated housing structures such as panels, beams and stairs. They have a short construction period and low construction cost. Modular integrated houses are the most integrated and industrialized type of prefabricated buildings. Multiple modules are transported to the construction site for combination to quickly form a complete building. This way of building houses is easy to transport, install, disassemble and reuse.

[0004] Taking environmental protection issues into consideration, ecological material panels can be used in the construction process of modular integrated houses. The ecological material panels can be quickly assembled at the construction site, which not only has good thermal insulation and heat insulation properties, but also can reduce the generation of construction waste.

[0005] In the process of using ecological material boards to build modular integrated houses, we must consider the construction speed and ensure the stability and firmness of the house construction on the basis of maintaining the speed. The construction of the foundation determines the overall stability of the house. At present, the foundation is mostly built manually, which is slow; the splicing between biomass boards determines the firmness and service life of the house. When splicing boards, the common method is to cast the splicing gaps on one side multiple times, which is time-consuming. When encountering thicker boards, the gaps cannot be completely filled, and external moisture and air will penetrate into the building through the gaps, reducing the service life of the house.

[0006] How to quickly and stably build the foundation and tightly splice the panels is an important issue in the current modular integrated house construction process. Summary of the invention

[0007] The invention provides a modular integrated house and a construction method thereof.

[0008] The technical solution of the present invention is as follows:

[0009] A modular integrated house, comprising: a printed foundation frame, a plurality of modularly produced wall panels, and a plurality of modularly produced floor panels.

[0010] The plurality of modularly produced wall panels are assembled to the preset positions of the foundation frame and are fixedly connected to the foundation frame; the plurality of modularly produced floor panels are assembled to the preset positions above the wall panels and are fixedly connected to the wall panels.

[0011] The assembly gap between two adjacent wall panels is less than 4mm, and the assembly gap between adjacent floor slabs is less than 4mm.

[0012] Also included is a modular integrated house construction method, comprising the following steps:

[0013] S1.

[0016] S4, floor slab assembly: hoist the floor slabs of different sizes according to the preset order, install them to the corresponding positions above the wall panels, and connect and fix the floor slabs and wall panels;

[0017] S5. Seam grouting treatment: A double-sided seam grouting device is used to perform double-sided seam grouting on a gap between two adjacent wall panels. The double-sided seam grouting device includes a first seam grouting component and a second seam grouting component connected by a rope of a specific length, and the end of the first seam grouting component connected to the rope can move, and the second seam grouting component is detachably connected to the rope, and both the first seam grouting component and the second seam grouting component are provided with grouting holes, and the direction of the grouting holes is perpendicular to the wall panels.

[0019] Print and generate the outer frame of the foundation. The outer frame of the foundation includes several straight lines connected in sequence. The intersection of any two connected straight lines is set as the starting point.

[0020] Starting from the starting point, set branch points and corresponding serial numbers at specific intervals in the clockwise or counterclockwise direction on the outer border.

[0021] According to the serial number, the nozzle is moved along the preset direction and distance at each branch point position to print and generate a number of foundation branch line frames inside the outer frame of the foundation. Based on the several branch foundation branch line frames, the internal space of the outer frame of the foundation is divided into a number of closed unit intervals.

[0022] Furthermore, the grouting hole is arranged in the middle of the first grouting component and the second grouting component, and two ropes are symmetrically arranged on the upper and lower sides of the grouting hole, and the two ropes move synchronously relative to the first grouting component.

[0023] Furthermore, the surfaces of the first caulking component and the second caulking component that are in contact with the gaps in the wall panels are both configured as flexible surfaces.

[0024] The diameter of the rope is smaller than the distance of the wallboard gap, and the diameters of the first grouting hole and the second grouting hole are the same and both are larger than the distance of the wallboard gap.

[0025] In the S1, the outer perimeter frame of the foundation and the surface of each foundation branch line frame facing away from the ground are provided with a rectangular groove, and the width of the rectangular groove is greater than the thickness of the wall panel to be assembled.

[0026] In the process of classifying and assembling the wall panels to be assembled in S3, the vertical component support device is used to temporarily support the assembled wall panels, and the position and angle of the wall panels are adjusted to align them with the placement frame line; after the foundation is poured, the vertical component support device is disassembled.

The present invention generates a foundation frame by quickly printing based on a preset printing path according to the designed foundation three-dimensional model and preset printing parameters, thereby realizing rapid construction of the foundation, reducing manual operation and waiting time, and shortening the construction period. At the same time, the amount of printing material used during foundation printing can be precisely controlled, reducing material waste and reducing construction costs.

[0030] 2. The present invention uses a double-sided caulking device to caulk the gap between two adjacent wall panels on both sides, ensuring that the gap is completely filled, which can improve the sealing of the wall, prevent external moisture and air from penetrating into the wall panels, eroding the wall panels, and extend the service life of the modular integrated house; at the same time, the double-sided caulking makes the connection between the wall panels tighter, improving the firmness of the house construction. Compared with the single-sided multiple caulking operation, the double-sided caulking is faster and improves the construction efficiency.

[0031] 3. In the double-sided grouting work, the present invention automatically adjusts the tightness of the rope through the cylinder, so that the first grouting component and the second grouting component can be quickly and accurately attached to the wall panel, and the two grouting holes are automatically aligned with the wall gap, and the grouting slurry is evenly injected without manual alignment.

[0041] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0042] Example

[0043] This embodiment provides a modular integrated house and a construction method thereof. Figure 1 , a modular integrated house construction method comprises the following steps:

[0044] S1. Foundation printing: According to the designed foundation 3D model and preset printing parameters, the printing material is extruded from the nozzle based on the preset printing path on the ground to print and generate the foundation frame. The foundation frame includes the outer frame of the foundation and several foundation branch line frames inside.

[0045] Specifically, the printing parameters include printing speed, printing thickness, and printing material extrusion amount. Before printing the foundation, the ground needs to be leveled and debris on the foundation needs to be cleaned up.

[0046] The printing material is extruded from the nozzle based on the preset foundation position on the ground to print and generate a foundation frame. The foundation frame includes the outer frame of the foundation and several foundation branch lines inside. The specific steps are as follows:

[0047] Print and generate the outer frame of the foundation. The outer frame of the foundation includes several straight lines connected in sequence. The intersection of any two connected straight lines is set as the starting point.

[0048] Starting from the starting point, set branch points and corresponding serial numbers at specific intervals in the clockwise or counterclockwise direction on the outer border.

[0049] According to the serial number, the nozzle is moved along the preset direction and distance at each branch point position to print and generate a number of foundation branch line frames inside the outer frame of the foundation. Based on the several branch foundation branch line frames, the internal space of the outer frame of the foundation is divided into a number of closed unit intervals.

[0050] In this embodiment, the outer perimeter frame of the foundation and the surface of each foundation branch line frame facing away from the ground are provided with a rectangular groove, and the width of the rectangular groove is greater than the thickness of the wall panel to be assembled. The provision of the rectangular groove can ensure that the wall panel is stably and accurately installed in place during the subsequent wall panel assembly, and provides a positioning reference for the wall panel to be assembled, so that the wall panel can be quickly aligned during installation, thereby improving the construction efficiency of the modular integrated house during the construction process, and ensuring the overall stability of the house structure. The width of the rectangular groove is set to be greater than the thickness of the wall panel to be assembled, so that the wall panel to be assembled can be inserted into the groove, which plays a role in fixing the assembled wall panel.

[0051] S2. Construction layout: On the outer frame of the foundation and the surface of each straight line of the foundation frame facing away from the ground, set placement frame lines of different sizes at preset positions according to the design drawings, corresponding to different types of wall panels to be assembled.

[0052] Specifically, in this step, placement frame lines of different sizes are set, and ink lines can be used in conjunction with steel tape measure measuring tools to mark the placement frame lines on the outer border of the foundation and the surface of each foundation straight line frame facing away from the ground to ensure that the lines are clear and accurate.

[0053] In this embodiment, the different types of wall panels to be assembled include door wall panels, window wall panels, and main wall panels. The main wall panels are the entire wall panels that constitute the main structure of the house, without door openings or window openings, while the door wall panels have door openings of specific sizes reserved at specific positions on the wall panels, and the window wall panels have window openings of specific positions and sizes reserved at specific positions on the wall panels.

[0054] S3. Wall panel assembly: The wall panels to be assembled are classified and assembled according to the position and size of the frame lines. After all the wall panels are assembled, the foundation is poured along the preset pouring path at the assembly position of the wall panels and the foundation.

[0055] Specifically, during the wall panel assembly process, lifting equipment is used to lift the wall panels. All wall panels are pre-set with lifting rings. Different types of wall panels are moved to the preset placement frame line positions respectively, and then the position and angle of the wall panels are manually fine-tuned. After the wall panels basically match the shape of the placement frame lines, they are clipped into the rectangular grooves of the foundation frame.

[0056] When classifying and assembling the wall panels to be assembled, use the vertical component support device to temporarily support the assembled wall panels, adjust the position and angle of the wall panels to align them with the placement frame line; preliminarily fix the wall panels to prevent them from shifting during the pouring process. The foundation pouring can use pouring equipment to evenly pour concrete or other pouring materials into the gap between the wall panels and the foundation, so that the wall panels and the foundation are completely fixed and assembled. After the foundation pouring is completed, the vertical structure support device can be removed.

[0057] S4. Floor slab assembly: hoist the floors of different sizes according to the preset order, install them to the corresponding positions above the wall panels, and connect and fix the floor slabs and wall panels.

[0058] During the floor slab assembly process, the floor slabs are lifted one by one using lifting equipment and moved to the corresponding position above the wall slabs for installation. All floor slabs are also pre-installed with lifting rings. To connect and fix the floor slabs and wall slabs, self-tapping screws can be inserted obliquely from the top of the floor slabs to connect them with the wall slabs, and then concrete is poured at the joints between the floor slabs and the wall slabs to fill the gaps at the joints between the floor slabs and the wall slabs.

[0059] S5, caulking treatment: the wallboard gap between two adjacent wallboards is caulked on both sides by a double-sided caulking device, the double-sided caulking device comprises a first caulking component and a second caulking component connected by a rope 9 of a specific length, and the end of the first caulking component connected to the rope 9 can be moved, and the second caulking component is detachably connected to the rope 9, and the first caulking component and the second caulking component are both provided with grouting holes, and the direction of the grouting holes is perpendicular to the wallboard,

[0060] The second caulking component and the rope 9 are disassembled, and then the rope 9 is manually passed through the gap of the wall panel and connected to the second caulking component again. Then, the electric cylinder 5 is set to connect the adjustment rope 9 and adjust the rope 9 to be tight through the movement of the telescopic moving end 6 of the electric cylinder 5. The two caulking machines are turned on to grout through the grouting holes, and the two caulking machines are connected in communication and discharge slurry synchronously. At the same time, the tension of the rope 9 is adjusted by the telescopic adjustment of the electric cylinder 5, and the positions of the first caulking component and the second caulking component are adjusted and adjusted in the vertical direction until the caulking operation of this wall joint is completed. In this step, different from the conventional caulking operation, a single worker can complete the double-sided caulking of the wall joint at the same time without switching positions back and forth inside and outside the house. First of all, the diameter of the rope 9 is generally set to be less than 1 mm, so it is in the process of moving and It will not cause a significant impact on the caulking material, and, through the above, a single worker can control the extension of the electric cylinder and adjust the distance between the first caulking component and the second caulking component at any position outdoors or indoors, thereby achieving clamping with the wall and relative loosening of the wall, and then can move up and down in position according to needs to complete the caulking operation, and during the caulking process, the first caulking component and the second caulking component can form a shielding effect on both sides of the wall seam, thereby avoiding the overflow of the caulking material and ensuring the filling effect of the caulking material on the wall seam. This type of equipment has a significant improvement significance for the construction of thicker wall panels. Due to the thickness of the wall, the middle section of the conventional caulking wall seam is easily left empty, and the present device fills in this way, which can improve the above problem.

[0061] The grouting process also includes setting a strip of wood for support under the gap between two adjacent floor slabs, and grouting the gap on one side of the floor slab above the floor slab. The width of the strip of wood is set to be larger than the gap width between the two adjacent floor slabs to ensure that sufficient support can be provided. When grouting the gap on one side of the floor slab above the floor slab, a pouring gun can be used to inject the grouting material from the side of the floor slab gap away from the ground until the grouting material fills the entire floor slab gap, thereby improving the overall stability of the floor slab.

[0062] In this embodiment, the double-sided caulking device includes a first caulking component and a second caulking component connected by a rope 9 of a specific length. Both the first caulking component and the second caulking component are provided with grouting holes, and the directions of the grouting holes are perpendicular to the wall panel. The grouting holes are respectively arranged in the middle of the first caulking component and the second caulking component.

[0063] Two ropes 9 are symmetrically arranged on the upper and lower sides of the grouting hole. The two ropes 9 move synchronously relative to the first grouting component, and the end of the first grouting component connected to the rope 9 can move, and the second grouting component is detachably connected to the rope 9. Through the above method, the rope 9 and the grouting hole can be in the same vertical direction. When located in the wall seam, it can be ensured that the grouting hole is located at the center of the wall seam. After that, the grouting hole can be set as a circular hole with a long hole, and the long hole is a vertical hole, so that the above device can be better matched for grouting operations, and the width of the long hole is not greater than the width of the wall seam.

[0064] Combine the following Figure 2-6 The double-sided caulking device is introduced in detail. The double-sided caulking device includes a first caulking component and a second caulking component connected by a rope of a specific length. The first caulking component and the second caulking component are both provided with grouting holes, and the grouting holes include a first grouting hole provided on the first caulking component and a second grouting hole provided on the second caulking component. The double-sided caulking device includes a first caulking component and a second caulking component connected by a rope of a specific length 9. The first caulking component and the second caulking component are both provided with grouting holes, and the grouting holes include a first grouting hole 4 provided on the first caulking component and a second grouting hole 14 provided on the second caulking component. The first grouting component includes a first rectangular fixing block 1 which is fitted with one side of the wall panel gap. A rope adjusting portion 2 whose axis is parallel to its long axis is provided on the surface of the first fixing block 1 facing away from the wall panel gap. First rope limiting holes 3 which vertically penetrate to the surface of the first fixing block 1 which is fitted with the wall panel gap are symmetrically provided at both sides of the long axis of the rope adjusting portion 2 which is facing away from the surface of the wall panel gap. At the same time, a first grouting hole 4 which vertically penetrates to the surface of the first fixing block 1 which is fitted with the wall panel gap is provided at the middle position of its long axis.

[0065] The rope adjusting part 2 is perpendicular to the first fixed block 1 and is attached to the wall panel gap surface and is fixedly connected to the side surface parallel to the long axis of the rope adjusting part 2 with an electric cylinder 5. The telescopic movable end 6 of the electric cylinder 5 is fixedly connected to the rope traction part 7. The rope traction part 7 includes a first strip bracket and a second strip bracket that are perpendicular to each other. One end of the first strip bracket is fixedly connected to the telescopic movable end 6, and the other end is connected to one end of the second strip bracket. The first strip bracket is parallel to the long axis of the rope adjusting part 2, and a second rope limiting hole 8 is provided on the surface facing away from the wall panel, which penetrates to the first fixed block 1 and is attached to the wall panel gap surface.

[0066] The second grouting component includes a rectangular second fixing block 10 which is fitted with the other side of the wall panel gap, a first rope fixing hole 12 corresponding to the position of the first rope limiting hole 3 is arranged in the direction of the long axis of the second fixing block 10, a rope fixing portion 11 with an axis parallel to its long axis is arranged on the surface of the second fixing block 10 away from the wall panel gap, rope end clamping portions 13 are symmetrically arranged on both sides of the long axis of the rope fixing portion 11 away from the wall panel gap surface, and a second grouting hole 14 is arranged vertically through the first fixing block 1 and fitted with the wall panel gap surface at the middle position of its long axis.

[0067] One end of each of the two ropes 9 passes through the two second rope limiting holes 8 from the first strip bracket facing the first fixing block 1, and then passes through the two first rope limiting holes 3 on the rope adjustment part 2 facing away from the wallboard. After passing through the first rope limiting holes 3, the ropes pass through the wallboard gap and pass through the second fixing block 10 facing the wallboard to the two first rope fixing holes 12. After passing through, the ends of the ropes 9 are fixed by the two rope end clamping parts 13. This arrangement of the ropes 9 can make the first caulking component and the second caulking component fit tightly on the wallboard during the double-sided caulking operation, ensuring the stability of the double-sided caulking device during the working process.

[0068] When performing double-sided grouting, the tightness of the rope 9 is adjusted by the movement of the telescopic moving end 6 of the electric cylinder 5, so that the double-sided grouting device moves along the wall panel gap, and the grouting slurry is injected into the wall panel gap through the first grouting hole 4 and the second grouting hole 14 at the same time until the wall panel gap is filled.

[0069] Specifically, the tightness of the rope 9 is adjusted by the movement of the telescopic movable end 6 of the electric cylinder 5. The telescopic movable end 6 of the electric cylinder 5 moves away from the electric cylinder 5, and the rope 9 is pulled to tighten the rope 9, so that the first grouting component and the second grouting component are respectively pressed against the wall panels on both sides, and the first grouting hole 4 and the second grouting hole 14 are automatically aligned with the wall panel gaps. At this time, the grouting slurry is quickly injected into the wall panel gaps through the first grouting hole 4 and the second grouting hole 14 at the same time.

[0070] When double-sided grouting is performed on the wallboard, the double-sided grouting device is manually moved from bottom to top along the wallboard gap. After the grouting slurry at the current position is filled, it needs to be moved to the next position of the wallboard gap. The telescopic moving end 6 of the electric cylinder 5 moves close to the electric cylinder 5, and the rope 9 is relaxed. The electric cylinder 5 is manually held to move the double-sided grouting device upward along the wallboard gap. When it reaches the predetermined position, the rope 9 is tightened by the electric cylinder 5 to fix the first grouting component and the second grouting component to perform double-sided grouting; until the wallboard gap is filled.

[0071] After the double-sided caulking is completed, the rope end clamping part 13 is loosened, and the second caulking component is separated from the first caulking component.

[0072] The surfaces of the first caulking component and the second caulking component that are in contact with the gaps in the wall panels are both configured as flexible surfaces.

[0073] The diameter of the rope 9 is smaller than the distance of the gap in the wallboard, and the diameters of the first grouting hole 4 and the second grouting hole 14 are the same and both are larger than the distance of the gap in the wallboard.

[0074] Furthermore, the present embodiment also provides a modular integrated house, including: a printed foundation frame, a plurality of modularly produced wall panels, and a plurality of modularly produced floor slabs, wherein the plurality of modularly produced wall panels are assembled to preset positions of the foundation frame and fixedly connected to the foundation frame; the plurality of modularly produced floor slabs are assembled to preset positions above the wall panels and fixedly connected to the wall panels, and the assembly gap between two adjacent wall panels is less than 4 mm, and the assembly gap between adjacent floor slabs is less than 4 mm.

[0075] In a modular integrated house and its construction method provided in this embodiment, after the floor slab is assembled, the first floor of the house is basically assembled, and the multi-story house can be assembled on this basis. Taking the construction of a two-story modular integrated house as an example, after the first floor of the house is caulked, the line is laid out on the floor of the first floor of the house, the installation position of the second floor wallboard is determined, and then the second floor of the house is assembled, and the wallboard gaps between the second floor wallboards are caulked. Further, the pre-assembled roof is hoisted and assembled and installed on the second floor of the house. The construction of multi-story modular integrated houses can effectively solve the land area and is also in line with the concept of environmentally friendly construction.

[0076] The present invention quickly prints and generates a foundation frame based on a preset printing path according to the designed foundation three-dimensional model and preset printing parameters, thereby realizing rapid construction of the foundation, reducing manual operation and waiting time, shortening the construction period, reducing material waste, and reducing construction costs. The present invention uses a double-sided grouting device to perform double-sided grouting on the wallboard gap between two adjacent wallboards, ensuring that the wallboard gap is completely filled, improving the sealing of the wall body, preventing external moisture and air from penetrating into the wallboard, causing erosion to the wallboard, and extending the service life of the modular integrated house; at the same time, the double-sided grouting makes the connection between the wallboards tighter and improves the firmness of the house construction. Compared with the single-sided multiple grouting operation, the double-sided grouting is faster and improves the construction efficiency. In addition, during the double-sided grouting work, the rope tension is automatically adjusted by the cylinder, so that the first grouting component and the second grouting component can be quickly and accurately attached to the wallboard, so that the two grouting holes are automatically aligned with the wall surface gap, and the grouting slurry is evenly injected without manual alignment, which can significantly improve the efficiency of grouting the wallboard, and can also flexibly adapt to wallboard gaps of different depths.
