DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the invention is described clearly and completely below in conjunction with specific embodiments.

[0025] like Figures 1 to 4 The figure shows a connection structure for low- and medium-rise prefabricated buildings, which includes a wall panel 1, a floor panel 2, a wall panel connector 3 and a floor panel support 4. The wall panel connector 3 is provided with mounting grooves 3-1 on the upper and lower sides. Several wall panels 1 are fixedly installed in the mounting grooves 3-1, and the wall panels 1 are fixedly connected to the wall panel connector 3 by bolts 5 to form a stable connection structure.

[0026] The side walls of the wall panel connectors 3 are provided with side wing panels 3-2 for supporting the floor slabs 2. Several of the wall panel connectors 3 are fixedly connected end to end to form a rectangular frame. The wall panel connectors 3 are welded and fixed to each other, and their usage and the size of the rectangular frame formed are set according to the building area.

[0027] The floor support members 4 are fixedly connected to the wall panel connectors 3. Several of the floor support members 4 divide the rectangular frame formed by the wall panel connectors 3 into several rectangular floor installation frames. The floor panels 2 are laid within the floor installation frames and supported by the side panels 3-2 and the floor support members 4. The floor support members 4 are perpendicular to the wall panel connectors 3 to which they are connected and are welded to the wall panel connectors 3 on site.

[0028] The main body of the wall panel connector 3 is H-shaped, with mounting grooves 3-1 formed at the top and bottom. The sidewalls of the main body secure the side panels 3-2. The metal plates on either side of the mounting groove 3-1 are 30mm thick, and the groove 3-1 is 120mm deep. The web and side panels 3-2 within the groove 3-1 are 30mm thick, and the side panels 3-2 are 50mm wide.

[0029] The floor support 4 includes a support plate 4-1 and a positioning partition 4-2. The positioning partition 4-2 is vertically positioned in the middle of the support plate 4-1, with the two sides of the support plate 4-1 used to support different floor slabs. The support plate 4-1 is 10 mm thick, and the positioning partition 4-2 is 5 mm thick and 120 mm high. The support plates 4-1 on both sides of the positioning partition 4-2 are both 50 mm wide.

[0030] The wall panel connectors 3 and the floor support members 4 are both prefabricated with hot-dip galvanized steel to prevent the steel from rusting.

[0031] The wall panel 1 includes a wall panel body 1-1, an inner wall layer 1-2, and an outer wall layer 1-3. The wall panel body 1-1 is the load-bearing layer. At the connecting end of the wall panel 1, the wall panel body 1-1 protrudes from the inner wall layer 1-2 and the outer wall layer 1-3 to form a protrusion that fits into the mounting groove 3-1. The wall panel 1 is installed in the mounting groove 3-1 via the protrusion. The inner wall layer 1-2 and the outer wall layer 1-3 at the connecting end are flush with the upper end surfaces on both sides of the mounting groove 3-1. The height of the protrusion matches the depth of the mounting groove 3-1.

[0032] The inner wall layers 1-2 are decorative layers that can be customized to meet individual needs. The outer wall layers 1-3 are thermal insulation layers, decorative layers, sound insulation layers, or waterproof layers, etc., depending on the building's environment and actual needs.

[0033] The bottom surface of the floor slab 2 is provided with recessed portions 2-1 around its perimeter for mating with the side wing panels 3-2 and the floor support members 4. A boss 2-2 is formed in the center of the bottom surface of the floor slab 2. The boss 2-2 is flush with the bottom surfaces of the side wing panels 3-2 and the floor support members 4. The height of the boss 2-2 is consistent with the thickness of the support panel 4-1.

[0034] Wall panel 1 has a span of 2400 mm and a height of 2800 mm. The wall panel body 1-1 is constructed of a lightweight composite panel formed by cold-bent thin-walled steel frames filled with polystyrene particles. Its thickness ranges from 100 mm to 200 mm, preferably 150 mm. The width of the mounting slot 3-1 matches the thickness of the wall panel body 1-1.

[0035] The inner wall layers 1-2 and the outer wall layers 1-3 can be made of foam concrete with a thickness of 30mm-100mm, preferably 30mm. The floor slab 2 can be made of a composite slab or a hollow prefabricated slab with a thickness of 100mm-120mm. For low- and medium-rise buildings, this can ensure the safety and comfort of the floor slab under normal use, effectively resist deformation, and meet structural requirements without increasing the building's deadweight.

[0036] This embodiment Figure 1 The figure shows the connection structure in a two-story building, so the wall panel only has a protrusion on one side. If there are three or more floors, the wall panels on the middle floor need to have protrusions on the top and bottom to connect with the installation grooves.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
