Description

Technical Field

[0001] This utility model relates to the field of passive house technology, and in particular to a steel-concrete modular passive house with built-in insulation. Background Technology

[0002] With the continuous progress of society and the growth of the population, more and more buildings have been built in both cities and rural areas to meet people's housing needs. However, existing buildings have a large demand for external energy, and with the continuous consumption of energy, people will also pay a relatively large expense. In order to reduce energy consumption and expenses, people have invented a passive house. The energy consumption of a passive house can be reduced by 75%-90% per year compared to traditional buildings. At present, some common skeleton house structures are built by assembling the keel on site. However, houses built with keel structures need to be assembled on site. Although this construction method can shorten the construction period compared to traditional concrete structures, on-site assembly still requires manual labor, which is not conducive to the control of construction costs.

[0027] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1-8 As shown in the figure, the steel-concrete modular insulated passive house described in this embodiment includes a house main body on the installation foundation. The house main body includes a prefabricated external wall frame 1, a prefabricated internal wall frame 2, and a prefabricated flat roof frame 3 at the top of the wall.

[0030] The prefabricated exterior wall frame 1 includes two symmetrical wall frames. The corners of the two wall frames are fixedly connected by square tube sections 4. An insulation layer 5 is provided between the wall frames. Support members extending towards the insulation layer 5 are also provided between the two wall frames. Metal mesh 6 is provided on the outer side of each of the two wall frames.

[0031] The prefabricated interior wall frame 2 also includes two symmetrical wall frames. The corners of the two wall frames are fixedly connected by four square tubes. There are also connecting steel bars 15 between the two wall frames. Metal mesh 6 is set on the outside of the two wall frames.

[0032] Concrete 7 is poured inside the wall frame of the precast exterior wall frame 1 and the wall frame of the precast interior wall frame 2.

[0033] The prefabricated flat roof frame 3 includes a truss bottom frame, on which several vertical support steel bars 8 are evenly distributed. The top of the horizontal support steel bars 8 in the same row is provided with horizontally placed threaded steel bars 10. Above the horizontally placed threaded steel bars 10, several longitudinally arranged threaded steel bars 10 are arranged side by side. The lower end of the truss bottom frame is covered with a metal mesh 6, and concrete 7 is poured on top of the metal mesh 6.

[0034] The wall frame includes two horizontal square tubes 11 at the top and bottom, and several vertical square tubes 11 are evenly distributed between the horizontal square tubes 11 at the top and bottom. Several threaded steel bars 10 are arranged between the vertical square tubes 11, and the threaded steel bars 10 are horizontally placed on each vertical square tube 11.

[0035] The vertical square tubes 11 within the wall frame can also be replaced by steel bars.

[0036] The support is fixed on the vertical square tube 11 inside the outer wall frame, and the connecting steel bar 15 is fixed on the vertical square tube 11 inside the inner wall frame.

[0037] The truss bottom frame includes several square tubes 11 evenly distributed in the horizontal and vertical directions. Each square tube 11 makes the truss bottom frame grid-like. Multiple supporting steel bars 8 are evenly distributed along each of the horizontally arranged square tubes 11. The horizontally arranged threaded steel bars 10 are welded to the top of the supporting steel bars 8 arranged in the same row. The longitudinally arranged threaded steel bars 10 are tied or welded above the horizontally arranged threaded steel bars 10.

[0038] The transverse spacing between the supporting steel bars 8 is 300mm-500mm.

[0039] The support includes threaded connecting rods 12 fixed at both ends of vertical square tubes 11 in the precast exterior wall frame 1. The two ends of the threaded connecting rods 12 are connected to the vertical square tubes 11 on both sides. The threaded connecting rods 12 extend towards the insulation layer 5 and are inserted into the insulation layer 5. A plastic connector 13 is provided inside the insulation layer 5, with insertion holes at both ends. The ends of the threaded connecting rods 12 located in the insulation layer 5 are inserted into the insertion holes of the connector 13. Internal threads can be provided in the insertion holes to prevent the threaded connecting rods 12 from falling out. The connecting rod 12 is also provided with a support pad 14 that abuts against the side wall of the insulation layer 5. The threaded connecting rods 13 at the upper and lower ends are staggered. The threaded connecting rod 12 is provided with an external thread. An adjusting nut 9 is screwed onto the threaded connecting rod 12 at the position corresponding to the support pad 14. By turning the adjusting nut 9, the position of the support pad 14 can be adjusted to adapt to insulation layers of different thicknesses, and the support pad 11 can abut against the outside of the insulation layer 5. A metal washer is also provided between the support pad 11 and the adjusting nut 9.

[0040] The threaded connecting rod 13 is connected to the vertical square tube 11 in the wall frame of the prefabricated exterior wall frame 1 via a broken bridge. One end of the threaded connecting rod 13 connected to the wall frame is also connected to the metal mesh mold 6 on both sides, thereby connecting the metal mesh mold 6 on both sides to the wall frame on both sides inside the exterior wall frame into a whole. The position of the support pad 14 can be adjusted according to the thickness of the insulation layer 5.

[0041] After the connecting steel bar 15 is welded to the vertical square tube 11 in the precast inner wall frame 2, it is also fixedly connected to the metal mesh mold 6 in the precast inner wall frame.

[0042] The thickness of insulation layer 5 can be increased according to construction needs to meet the passive house index requirements. Increasing the thickness of the insulation layer only increases the material cost of the insulation board, without increasing other costs or construction costs.

[0043] The threaded connecting rod 12 and the connecting steel bar 15 are respectively fixedly connected to the metal mesh mold 6 on their respective wall frames, which can enhance the fixing effect of the metal mesh mold 6 and thus prevent the mold from expanding during concrete pouring.

[0044] Preferably, the spacing of the horizontally placed square tubes 11 inside the wall frame is 100mm-300mm, and the spacing of the threaded steel bars 10 inside the wall frame is 100mm-300mm.

[0045] Preferably, the spacing of the longitudinally arranged square tubes 11 inside the truss bottom frame is 100mm-300mm, and the spacing of the threaded steel bars 10 above the truss bottom frame is 100mm-300mm.

[0046] Preferably, the diameter of the threaded steel bar 10 is 8mm-16mm.

[0047] Preferably, the metal mesh mold 6 is a reinforced expanded metal mesh or a steel wire mesh.

[0048] like Figure 9 As shown, an arrangement of the corner of an exterior wall adopts a right-angle structure. Square tubes 11 form a right-angle frame, and a right-angle insulation layer 5 is arranged inside the right-angle frame. A metal mesh is also installed on the outside of the right-angle frame formed by the square tubes 11. Several threaded steel bars 10 are horizontally placed inside the vertical square tubes 11. Support members facing the insulation layer 5 are also provided on the vertical square tubes 11 inside the right-angle frame.

[0049] like Figure 10 As shown, another arrangement method for the corners of the exterior walls and the connection between the interior and exterior walls is to set up reinforced structural columns at the corners and the connection between the interior and exterior walls. The reinforced structural columns serve as earthquake-resistant columns. Then, the prefabricated exterior wall frame 1 and the prefabricated interior wall frame 2 are installed with the reinforced structural columns and finally concrete is poured.

[0050] In the construction process of this utility model, the exterior wall frame, interior wall frame, and flat roof frame are first prefabricated in the factory. According to the size design of the house, the prefabricated frames are transported to the construction site. Workers assemble the prefabricated exterior wall frame, interior wall frame, and flat roof frame in sequence on site. After assembly, concrete is poured into the gaps in each frame to form a whole, thus completing the construction of the house. After setting metal mesh molds on the wall frames of the interior and exterior walls, there is no need to use carpentry formwork. Concrete can be poured directly into the walls, which greatly saves construction costs and reduces the contracting cost.

[0051] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
