Technical Field

[0001] This invention belongs to the field of foundation structure construction technology, and particularly relates to a foundation adaptive connection device and installation method for low-rise prefabricated steel structure farmhouses. Background Technology

[0002] The design and construction of rural houses need to take into account the natural environment, economic conditions, and living habits of rural areas. With the development of modern construction technology, the construction materials and methods of rural houses are also constantly improving, evolving from traditional brick and wood structures to new building forms such as light steel structures and steel structures. In the past, the construction of low-rise rural houses mostly used cast-in-place construction methods for the foundation, which required wet operations such as formwork, steel bar binding, and concrete pouring. The construction period was long, the on-site workload was large, and it was significantly affected by the weather.

[0003] In existing technologies, the prefabricated foundation beams and pile foundations are relatively simple in construction and have poor connection flexibility. In the construction of low-rise farmhouses, different terrains and building heights require diverse foundations. As mentioned earlier, traditional prefabricated foundations cannot be adapted and adjusted. Low-rise farmhouses cannot be standardized in construction and have a low level of modularity. In many cases, the foundation structure is still built by cast-in-place construction. Summary of the Invention

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] This invention provides a foundation adaptive connection device for low-rise prefabricated steel structure farmhouses, such as... Figures 1-11 As shown, the self-adaptive connection device for the foundation of a low-rise prefabricated steel structure farmhouse includes:

[0042] A first ground beam 100 is provided with a plurality of sets of assembly grooves 101 for connection. The assembly grooves 101 are recessed inward and surround the outer wall of the first ground beam 100. The first ground beam 100 includes parallel metal plates 120, connecting steel bars 130 connecting the metal plates 120, and a concrete layer 110. The metal plates 120 and the connecting steel bars 130 form an inner skeleton. The concrete layer 110 is subjected to the action of the mold.

[0043] The concrete layer 110 wraps around the metal plate 120 and the connecting steel bars 130 to form the outer side of the inner skeleton.

[0044] The second ground beam 300 includes a concrete main body 350 and a connecting part located at the front end of the main body. The connecting part includes a socket 320, a base 330, and an upper pressure plate 310 suspended on one side of the socket 320. A connecting rod 340 is provided on the side of the base 330 away from the socket 320. The connecting rod 340 is welded to the steel reinforcement skeleton inside the concrete main body 350, and the concrete main body 350 is also wrapped around the outside of the connecting rod 340.

[0045] The connector 200 includes a U-shaped seat 210 and a plug-in seat 220 disposed on one side of the U-shaped seat 210. The U-shaped seat 210 is snapped into the assembly groove 101 from bottom to top. The plug-in seat 220 and the socket 320 are plugged into each other. The upper pressure plate 310 extends above the U-shaped seat 210 and wraps around the first ground beam 100 with the U-shaped seat 210.

[0046] The support base is pre-embedded underground and forms a point array structure. The first ground beam 100 is bolted to the support base to form an outer frame. The second ground beam 300 is connected between two sets of parallel first ground beams 100.

[0047] The following construction methods shall be used when assembling the above equipment;

[0048] Step 1: Install the corresponding number and structure of support bases according to the construction area. The support bases are arranged in a point array distribution.

[0049] Step 2: The first ground beam 100 is initially placed according to the position of the support seat, and an appropriate number of second ground beams 300 are arranged in parallel longitudinally or laterally.

[0050] Step 3: Fix and assemble the first ground beam 10, which is placed parallel to the second ground beam 300, into the support base;

[0051] Step 4: The first ground beam 100, which is perpendicular to the second ground beam 300, needs to be connected to the second ground beam 300. The U-shaped seat 210 is assembled into the assembly groove 101 from top to bottom. The second ground beam 300, which is perpendicular to the first ground beam 100, is inserted into the insertion seat 220 through the connecting part. The upper pressure plate 310 covers the upper half of the assembly groove 101. The upper pressure plate 310 is welded to the U-shaped seat 210.

[0052] Step 5: After the first ground beam 100 is connected to the second ground beam 300, it is lifted by a crane and inserted into the support base. The first ground beam 100, which is perpendicular to the second ground beam 300, is finally bolted to the support base. Finally, filling material is backfilled into the foundation to form the building foundation.

[0053] In this embodiment, the second ground beam 300 serves as an auxiliary beam structure. During construction, the second ground beam 300 is set up reasonably as needed. More assembly slots 101 can be set up. When applied, the second ground beam 300 is arranged in a suitable position according to the support needs, thereby improving the flexible configuration of the foundation of low-rise prefabricated buildings.

[0054] The second ground beam 300 and the first ground beam 100 are connected by a nested connection between the connector 200 and its own connecting part. Combined with the through-type structure design of the metal plate 120, the overall structural connection strength at the connection point is improved. Compared with the single arrangement of pre-embedded screw holes, the structural strength at the connection point is greatly improved.

[0055] In addition to bolt connections, when the U-shaped seat 210 is engaged in the assembly groove 101, the upper pressure plate 310 is welded to the side of the U-shaped seat 210 away from the socket 320, and the end face of the socket 320 that contacts the U-shaped seat 210 is also welded. The welding connection method further enhances the structure, the nested structure layout allows for better stress distribution, and the frame structure connection enhances the stability of the foundation.

[0056] In a preferred embodiment of this invention, the two sets of metal plates 120 are arranged in parallel, and the connecting steel bars 130 are connected between the two sets of metal plates 120 by welding to form an inner skeleton; a special rectangular ring is nested in the inner skeleton, and during the pouring of the concrete layer 110, the rectangular ring will form spaced assembly grooves 101 in the concrete layer 110.

[0057] In this embodiment, the metal plate 120 communicates with the outside through an assembly groove 101 opened on the first ground beam 100, and the metal plate 120 has pre-set screw holes for bolt connection; in the later assembly process, the U-shaped seat 210 is engaged in the assembly groove 101 and contacts the metal plate 120, and the U-shaped seat 210 and the metal plate 120 are fixedly connected by bolts.

[0058] In a preferred embodiment of this invention, the top of the support base is provided with an assembly slot for inserting the first ground beam 100, and the first ground beam 100 is fixedly connected to the support base by bolts.

[0059] In this embodiment, the support base can be a side base 410 with a single side angle structure. The side base 410 is provided with two sets of assembly slots, which are designed vertically. Figure 2 As shown, the side seats 410 are distributed at the four corners, while the first ground beams 100 are connected between the four sets of side seats 410 respectively, and the second ground beams 300 are arranged in parallel with the four sets of first ground beams 100 to form a rectangular structure inside.

[0060] like Figure 11 As shown, the support base can adopt a single-sided corner structure of side base 410 and a side-center base 420 as an intermediate transition member. The side base 410 and the side-center base 420 are distributed in a point array. The side base 410, the side-center base 420 and the center base 430 are connected by a first ground beam 100.

[0061] The side-center base 420 is equipped with an additional set of assembly slots on the basis of the side base 410. Two sets of assembly slots are arranged in parallel, and the remaining set is designed to be perpendicular to the other two sets of assembly slots. The two sets of parallel assembly slots help to construct two sets of first ground beams 100 arranged close to each other. By increasing the number of second ground beams 300 perpendicular to the first ground beams 100, the stability of the foundation is further improved. In the process of application, relevant technicians can combine different forms of side-center bases 420 and side bases 410, as well as first ground beams 100 and second ground beams 300 of different lengths according to the needs of the site.

[0062] Generally, the lengths of the first ground beam 100 and the second ground beam 300 are specified to be at least 3 meters, 5 meters, and 9 meters, respectively. When the number of floors is high, the number of the first ground beam 100 and the second ground beam 300 is increased. When the multi-story structure is staggered, the number of the second ground beam 300 under the high-rise structure is increased. The configuration is flexible in actual application.

[0063] In a preferred embodiment of this invention, the socket 320 is provided with a socket groove 301 for accommodating the insertion of the insertion seat 220, and the socket 320 is bolted to the insertion seat 220 entering the socket groove 301.

[0064] In this embodiment, the end face of the plug socket 220 parallel to the plugging direction is provided with a screw hole, and the end face of the socket 320 parallel to the plugging direction is also provided with a corresponding screw hole, and the corresponding screw holes are fixedly connected by bolts.
