[0042] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may also be beneficially combined in other embodiments.

[0043] It should be noted that: unless otherwise defined, the technical terms or scientific terms used in this article should be understood by people with ordinary skills in the field to which the utility model belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of this utility model do not express quantitative restrictions, but indicate the existence of at least one; the "first", "second" and "third" used in this article should not be regarded as restrictions on the order of components, but are only used to distinguish different components; "include" or "comprise" and other similar words indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0044] In order to more clearly describe the specific structural composition of the connection structure between the wall panels and the floor panels of the assembled light steel house, Figure 1-6 Describe this embodiment:

[0045] like Figure 1 or Figure 2 As shown, a connection structure for the wall panels and floor panels of assembled light steel houses includes a lower wall panel frame 3 and an upper wall panel frame 4, and a connecting member 1 is connected between the lower wall panel frame 3 and the upper wall panel frame 4;

[0046] The two opposite sides of the connecting member 1 are opposite to each other with floor frames 2, and the sides of the floor frames 2 are provided with bolt holes 201 for connecting with the external floor. Figure 6 The figure shows the structure in which the floor frame 2 on one side is connected to the external floor frame.

[0047] like Figure 1 and 3 As shown, the bottom of the floor frame 2 has a recessed portion 202; the bottom of the connecting member 1 is provided with two raised portions 101, and the bottoms of the floor frames 2 on both sides extend between the connecting member 1 and the lower wall panel frame 3, the connecting member 1 is connected to the lower wall panel frame 3 by fasteners, and the raised portions 101 are pressed and fixed in the corresponding recessed portions 202; the lower wall panel frame 3 and the upper wall panel frame 4 are switched by the connecting member 1, and the floor frame 2 is stuck between the lower wall panel frame 3 and the connecting member 1, so that the floor frame 2 and the wall panel can be stably connected; the connecting member 1 does not need fasteners such as bolts to be connected to each frame, and at the same time, the raised portions 101 and the recessed portions 202 enable the connecting member 1 to be accurately positioned during installation, thereby improving the efficiency of installation;

[0048] The connecting piece 1 is also connected to the upper wall panel frame 4 by fasteners, and the upper wall panel frame 4 is clamped in the opening between the tops of the two floor slab frames 2; during installation, the floor slab frames 2 on both sides have a guiding effect on the upper wall panel frame 4, which is conducive to the rapid docking of the upper wall panel frame 4 with the connecting piece 1 on the lower side; after the installation is completed, the floor slab frames 2 on both sides have a clamping effect on the upper wall panel frame 4, thereby enhancing the stability of the entire connection structure.

[0049] like Figure 2 As shown, the lower wall panel frame 3 and the upper wall panel frame 4 are respectively provided with positioning pins 5 on the sides facing the connecting member 1, and the connecting member 1 is provided with positioning holes corresponding to the positioning pins 5. The upper and lower surfaces of the connecting member 1 have two connecting holes, one of which is used for the fastener 6 to pass through, and the other is a positioning hole;

[0050] Specifically, the fasteners may be bolts, and the two connection holes at the bottom of the connecting member 1 for connecting the lower wall panel frame 3 may be set as light holes, and corresponding bolt holes corresponding to the light holes are set on the lower wall panel frame 3, and the bolts pass through the light holes at the bottom of the connecting member 1 and are threadedly connected to the bolt holes at the top of the lower wall panel frame 3; the two connection holes at the top of the connecting member 1 may be set as threaded holes, and the corresponding upper wall panel frame 4 is provided with a light hole at the bottom, and the bolts pass through the light holes at the bottom of the upper wall panel frame 4 and are threadedly connected to the threaded holes at the top of the connecting member 1;

[0051] The length of the connecting member 1 is much smaller than the length of the floor frame 2. There are multiple connecting members 1 spaced along the length direction of the floor frame 2 between the two floor frames 2. The connecting member 1 can still maintain the connection strength and can adapt to floor frames 2 of different lengths.

[0052] See also Figure 2 Since there are multiple connecting parts 1, the number of positioning pins 5 on the lower wall panel frame 3 corresponds to the number of connecting parts 1. One of the light holes at the bottom of the connecting part 1 is used as a positioning hole and is passed through by the positioning pin, so that each connecting part 1 is installed at the corresponding position of the lower wall panel frame 3; at least two positioning pins 5 are provided on the upper wall panel frame 4, and the upper wall panel frame 4 can be aligned by positioning with two of the connecting parts 1.

[0053] like Figure 4 As shown, the connecting member 1 is tubular, and the protrusion 101 is along the lower wall panel frame 3. A rib groove 102 is formed between the two protrusions 101 of the connecting member 1, and the fastener 6 connected to the lower wall panel frame 3 is located on the rib groove 102. The interior of the connecting member 1 has a reinforcing rib 103, and the reinforcing rib 103 is transitionally connected to the rib groove 102; the rib groove 102 and the reinforcing rib 103 can ensure the strength of a single connecting member 1 and ensure the stability of the entire structure after connection.

[0054] like Figure 3 and Figure 5As shown, the recessed portion 202 is specifically surrounded by a vertical edge 2021, a bottom edge 2022 and a folded edge 2023 which are sequentially connected on the lower side of the floor frame 2. The folded edge 2023 is pressed into the rib groove 102. The stability of the floor frame 2 between the lower wall panel frame 3 and the connecting member 1 is further ensured by pressing the folded edge 2023.

[0055] In the above embodiment, the area where the bolt hole 201 is provided on the floor frame 2 extends outward, forming a bolt installation cavity between the connecting member 1 and the floor frame 2. When the floor frame 2 is connected to the external floor frame by bolts, the bolt head is in the bolt installation cavity, which facilitates the tightening of the bolt and makes the outer side of the connection neat.

[0056] The middle part of the floor frame 2 extends outward, while the upper end remains tightened inward, and the upper ends of the floor frames 2 on both sides are pressed on both sides of the upper wall panel frame 4 respectively;

[0057] It is worth noting that the connection structure between the wall panel and the floor slab is a connection node. When the prefabricated light steel house has many floors, it has multiple nodes. The lower wall panel frame 3 and the upper wall panel frame 4 refer to the wall panel at the lower side of the node and the wall panel at the upper side of the node respectively, and they are not an absolute upper and lower relationship.

[0058] The parts not described in detail in this embodiment are prior art.

[0059] It should be noted that although the utility model is described through the above embodiments, the utility model can also have other multiple embodiments. Without departing from the spirit and scope of the utility model, it is obvious that those skilled in the art can make various corresponding changes and deformations to the utility model, but these changes and deformations should all fall within the scope of protection of the attached claims of the utility model and their equivalents.
