Detailed Implementation

[0036] To facilitate a better understanding of this utility model, the following examples are provided in conjunction with the accompanying drawings. These examples fall within the protection scope of this utility model, but do not limit the protection scope of this utility model.

[0037] Example 1

[0038] A modular U-shaped wall panel, such as Figures 1-2 As shown, the U-shaped wall panel 1 includes: a main body 11; side ends 12, disposed on both sides of the main body 11; and a U-shaped reinforcing member 2, disposed within the main body 11 and the side ends 12; the main body 11 and the side ends 12 are connected to form a U-shape; and the U-shaped reinforcing member 2 is partially located outside the side ends 12.

[0039] The U-shaped reinforcement can be made of steel bars arranged horizontally and vertically, and the horizontal and vertical joints are tightened with steel wire; the U-shaped reinforcement has an overall U-shaped structure to match the structure of the U-shaped wall panel.

[0040] U-shaped wall panels consist of a main body and side ends, which are connected to form a U-shaped structure. When in use, they have stronger bending resistance than single-type wall panels, which can improve the safety performance of the assembled house.

[0041] Example 2

[0042] like Figures 1-2 As shown, the length of the side end portion 12 is 0.1-0.25 times the length of the main body portion 11.

[0043] like Figures 1-2 As shown, a door opening 13 and / or a window opening 14 can be pre-set on the main body 11; the door opening 13 and the window opening 14 are located on the main body 11; the U-shaped wall panel 1 is provided with a through connecting hole 15 for connecting two adjacent wall panels in the horizontal direction.

[0044] like Figures 1-2 As shown, the U-shaped reinforcing member 2 further includes: a first reinforcing member 21, which is disposed within the main body 11 and the side end 12 and extends along the length direction of the main body 11, with both ends located outside the side end 12; a second reinforcing member 22, which is disposed within the main body 11 and the side end 12 and extends along the length direction of the main body 11, with both ends located outside the side end 12; the diameter of the second reinforcing member 22 is larger than the diameter of the first reinforcing member 21, and it is disposed near the upper and lower ends of the main body 11 and the side end 12.

[0045] like Figures 1-2 As shown, the U-shaped wall panel 1 also includes a filler 3, which is disposed inside the main body 11 and located on the side of the U-shaped reinforcing member 2; the thickness of the filler 3 is less than the thickness of the U-shaped wall panel 1.

[0046] To increase the strength of the U-shaped wall panel, reinforcing members, which can be steel bars, are installed inside. The U-shaped reinforcing members consist of a first reinforcing member and a second reinforcing member. The second reinforcing member has a larger diameter and is only installed at the top and bottom ends of the wall panel, while the first reinforcing member has a smaller diameter and is more numerous, distributed along the height of the wall panel. The difference in diameter between the two is more in line with the actual stress requirements. The combined use of the first and second reinforcing members enables the U-shaped wall panel to have better load-bearing capacity and can be used to connect with other wall panels to enhance the connection strength.

[0047] The first and second reinforcing members can be made of threaded steel bars of different grades. The first reinforcing member is composed of threaded steel bars arranged horizontally and vertically, with the connecting nodes tied together with steel wire to form a steel mesh. The horizontal first reinforcing member is set along the U-shaped structure of the U-shaped wall, with both ends extending outwards from the side ends. The second reinforcing member is set at the side end, with its length direction aligned with the height of the side end, and both ends bent into a U-shape, extending outwards from the side ends. Figure 4 As shown; at least two second reinforcing members are provided at intervals on one side end, and the non-bent part and the connection part with the first reinforcing member can be fixed by binding with steel wire; the horizontal and vertical arrangement of the reinforcing bars of the first reinforcing member is the existing conventional method, and the connection nodes also adopt the conventional steel wire binding method, which can meet the relevant standard provisions and usage requirements.

[0048] Filler components (not shown in the figure) can be installed inside the U-shaped wall panel and the type I wall panel. The filler components can be sound insulation layer, heat insulation layer, etc., all of which are made of existing materials to meet different usage requirements.

[0049] Before pouring concrete, a connecting plate 71 can be pre-embedded inside the U-shaped wall panel. A sleeve 73 is provided on the connecting plate 71. The connector 72 can be screwed down from the sleeve of the floor slab into the sleeve 73 of the U-shaped wall panel through a threaded connection. The vertically upward connector facilitates the connection and fixation between the U-shaped wall panel and the floor slab. The connector can be a screw rod, which is tightened with a nut after being connected to the floor slab.

[0050] A horizontal connecting hole 15 can be installed on the U-shaped wall. A sleeve 73 can be installed inside the connecting hole. The inner side of the sleeve can be provided with internal threads to connect two adjacent wall panels horizontally. If the adjacent wall panels horizontally are both U-shaped wall panels (e.g., Figure 11 As shown), the connecting hole is located on the side end, and a groove is provided on the inner side of the side end; when connecting, screw the connector through the two U-shaped wall panels, with both ends of the connector in the groove, and tighten the connector with a nut; if the U-shaped wall panels are adjacent to the same type of wall panel in the horizontal direction (such as...), the connecting hole is located on the side end, with a groove on the inner side of the side end. Figure 10 As shown in the figure, grooves are opened on the main body of the U-shaped wall panel and the first type of wall, respectively. The grooves are equipped with connecting holes, and the connecting holes are equipped with sleeves with internal threads. The two wall panels are connected by turning the connector. The two ends of the connector are in the grooves. The connector is tightened with nuts.

[0051] If two spaced connectors are used, a limiting plate can be installed in the groove of the two connected wall panels. The limiting plate has a hole at the position corresponding to the sleeve. When in use, the connector passes through the groove, the limiting plate, the sleeve, and the limiting plate from one side of the U-shaped wall panel and then extends into the groove of the adjacent wall panel. Then, the two ends of the connector are tightened with nuts.

[0052] Example 3

[0053] A modular prefabricated housing structure system, such as Figures 3-5As shown, it includes: a prefabricated house structural unit 10, including: a U-shaped wall panel 1 and a type wall panel 4 arranged opposite each other, arranged opposite each other and located on both sides of the side end 12; a type reinforcing member 5, located inside the type wall panel 4; a floor slab 6, located on top of the U-shaped wall panel 1 and the type wall panel 4; the type reinforcing member 5 is partially located outside the type wall panel 4; the side end 12 and the type wall panel 4 are arranged apart, forming a grouting area 41 between them; the U-shaped reinforcing member 2 is connected to the extended portion of the type reinforcing member 5 and is located within the grouting area 41.

[0054] The U-shaped wall panels, along with the type I wall panels and the floor slab, form a modular housing structure unit. To enhance the connection strength between the U-shaped and type I wall panels, the U-shaped and type I reinforcing members are connected and fixed (partially connected), forming a pouring zone between them. After connection, concrete is poured into the pouring zone so that both the U-shaped and type I reinforcing members are encased in concrete, further improving the connection strength between the U-shaped and type I wall panels. The floor slab is placed on top of the U-shaped and type I wall panels, and its own weight provides stability, meeting the usage requirements.

[0055] The U-shaped reinforcement and the type I reinforcement can be connected using existing methods, such as welding the connecting parts together by electric welding, or fixing the connecting parts by existing steel wire binding methods.

[0056] Type I reinforcing members can also use two different grades of steel bars. The installation method can refer to the installation method of the first and second reinforcing members of the U-shaped wall panel. One type of steel bar (the third reinforcing member, such as the first reinforcing member) is installed horizontally and vertically, with the joints tied with steel wire. The horizontal steel bars extend outwards from both sides of the type I wall. The other type of steel bar (the fourth reinforcing member, such as the second reinforcing member) is installed inside both sides of the type I wall, with its length direction aligned with the height of the type I wall and both ends bent into a U-shape, extending outwards from the side of the type I wall. Figure 4 As shown.

[0057] At least two fourth reinforcing members are installed at intervals on one side of the type I wall. The non-bent part and the node connecting the third reinforcing member can be fixed by steel wire binding. The horizontal and vertical arrangement of the reinforcing bars of the third reinforcing member is the existing conventional method, and the connecting node also adopts the conventional steel wire binding method, which can meet the relevant standard provisions and usage requirements.

[0058] After the first and second reinforcing members are connected, the grouting area can be grouted with C60 grout.

[0059] Example 4

[0060] like Figure 3 , Figure 7As shown, the prefabricated house structure system also includes: a connecting component 7, including: a connecting plate 71, which is embedded in the U-shaped wall panel 1; a connector 72, one end of which is connected to the connecting plate 71 and is set vertically upward; a sleeve 73, which is set in the floor slab 6 or the U-shaped wall panel 1 or the type 4 opposite to the connector 72; the connector 72 can extend into the sleeve 73.

[0061] like Figure 3 , Figure 5 As shown, a groove 61 is provided on the floor slab 6 on one side of the top of the sleeve 73.

[0062] like Figure 3 , Figure 5 As shown, the connecting components 7 are provided in at least two sets for connecting the U-shaped wall 1 and the floor slab 6.

[0063] like Figures 8-10 As shown, there are several prefabricated house structural units 10; adjacent prefabricated house structural units 10 can be connected horizontally and / or vertically; when connected horizontally, the main body 11 is provided with a through connection hole 15, and a sleeve 73 is provided in the connection hole 15, and two adjacent U-shaped walls 1 are connected by a connector 72.

[0064] The connecting components are used to connect the U-shaped wall panels to the floor slab to enhance the connection strength between them. Specifically, during the prefabrication of the U-shaped wall panels, connecting plates are embedded in appropriate positions, and connectors are connected to these plates. Sleeves with grooves at the top are embedded in the corresponding floor slabs. When the U-shaped wall panels and floor slabs are joined, the connectors extend upwards into the sleeves. The connectors can be screws, which are tightened onto the screws with nuts in the grooves. After the connection is completed, concrete is poured into the grooves to make the surfaces of the floor slabs flat.

[0065] The preferred method is to install sleeves on the connecting plate, and both are pre-embedded in the U-shaped wall panel. All sleeves used are internally threaded, and the connectors are screw rods. After the U-shaped wall panel, the type I wall panel, and the floor slab are assembled, the connectors (of appropriate length should be selected) are screwed down from the groove on the floor slab until the connectors abut against the connecting plate. Then, the nuts are screwed in from the top of the connectors. In this way, the connectors are not pre-embedded, and there are no connectors protruding outwards from the top of the U-shaped wall panel, which not only facilitates transportation but also avoids bumps.

[0066] Multiple sets of connection components can be installed, and connection plates and connectors can be prefabricated on a single-wall structure to securely connect the U-shaped wall or single-wall structure to the floor slab; at least two sets should be installed, with a corresponding number of grooves provided on the floor slab; for example... Figure 5 As shown, four sets of connection components are set up.

[0067] The connecting components can also be installed on a type of wall panel to connect and fix the type of wall panel to the floor slab.

[0068] A set of connecting components can be configured with several connectors as needed; such as Figure 6 As shown, there are two connectors, located on the main body and side ends of the U-shaped wall, respectively. Two sleeves are respectively installed on the corresponding floor slabs, and limiting plates 74 are also installed on the sleeves. The limiting plates 74 have holes corresponding to the positions of the sleeves, allowing the connectors to pass through the sleeves and limiting plates sequentially upwards. The sleeves and limiting plates restrict the position of the connectors. The connecting plate used in this case is L-shaped, as shown... Figure 7 As shown.

[0069] When the connecting plate, sleeve, and limiting plate are pre-embedded, they can be welded to the connecting parts of the nearby U-shaped reinforcement and type I reinforcement to avoid displacement during concrete pouring.

[0070] The prefabricated house structural unit is composed of U-shaped wall panels, type I wall panels, and floor slabs. In actual use, multiple prefabricated house structural units can be combined according to user needs. The combination can be horizontal, vertical, or both. When multiple prefabricated house units are combined horizontally, connection holes are provided on the U-shaped wall panels to enhance the connection strength between the units. Connectors are passed through the connection holes to connect two adjacent wall panels. The two ends of the connectors can be tightened with nuts.

[0071] The prefabricated house construction system of this invention can take many forms, and can be selected according to specific needs; only three transverse connection methods of the U-shaped wall panels are listed below. Figures 8-10 (Top view, without floor slabs): e.g. Figure 8 As shown, a prefabricated house structural unit is first constructed using U-shaped wall panels, type I wall panels, and a floor slab. Then, a wall connected to the U-shaped wall panels at both ends is installed inside this unit to create two rooms. Figure 9 As shown, both the left and right sides are prefabricated house structural units, spaced apart, and connected by two straight walls in the middle to form three rooms; as shown Figure 9 As shown, three prefabricated house structural units are horizontally connected to form three rooms; the above Figures 9-10 In the process, when the U-shaped wall panel is connected to the adjacent wall panel laterally, the wall panel has a groove with a sleeve pre-embedded inside. The sleeve has a limiting plate on both sides. The connector (bolt) passes through the limiting plate, sleeve and limiting plate in sequence from the groove, with both ends in the groove and tightened with nuts respectively. The sleeves of the adjacent wall panels are separate, but after the wall panels are assembled, they should be in relative positions to facilitate the passage of the connector.

[0072] like Figure 12 As shown, lifting rings are pre-embedded at the top of the U-shaped wall panel, the type I wall, and the floor slab, which are used to lift them to a suitable position with the help of hoisting equipment during demolding and assembly; they can be cut off after the wall panel and floor slab are assembled.

[0073] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0074] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
