Abstract
Description
Technical Field
[0001] This utility model relates to the field of modular building technology, and in particular to a concrete module and modular building. Background Technology
[0002] Modular integrated buildings are an important trend in the construction industry, representing the 4.0 era of prefabricated buildings. By integrating the exhaust ducts of bathrooms and kitchens into concrete modules, the integration rate of modules can be improved to a greater extent. However, after multiple concrete modules are assembled, their multiple exhaust ducts are spliced together to form a complete exhaust shaft. There are gaps at the splicing points of two adjacent exhaust ducts, which may cause the exhaust gas to leak out, directly affecting the building's durability and the comfort of the residents. Utility Model Content

[0029] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] Example 1
[0031] like Figure 1 As shown, this embodiment of the utility model provides a concrete module, which includes a connected module body and a flue unit 1. The flue unit 1 has an annular structure, and its transverse cross-section can be circular, rectangular, or other closed annular structures. The first and second connecting ends of the flue unit 1 are respectively provided with integrally formed shielding rings 11. The shielding rings 11 on the first connecting end of the flue unit 1 of one concrete module and the shielding rings 11 on the second connecting end of the flue unit 1 of another concrete module are connected in a complementary manner, such as... Figure 2 The flue unit 1 of two adjacent concrete modules shown is further provided with a pressing layer 2 that is pressed between the first connecting end and the second connecting end. Preferably, the pressing layer 2 is made of fireproof putty, which is soft, easy to shape, and facilitates the pressing of the flue unit 1 of two adjacent concrete modules, and can effectively withstand high temperature environments.
[0032] In this embodiment, the concrete module can partially block the exhaust gas by setting a protruding structure to prevent it from flowing out from the gap at the splice. At the same time, since the joint of the flue unit 1 of two adjacent concrete modules is also provided with a pressing layer 2 that presses against the first and second connecting ends, gaps can be avoided at the joint, further preventing the leakage of exhaust gas in the flue unit 1.
[0033] To further prevent gas leakage, the concrete module also includes a connecting ring 3. The connecting ring 3 is coaxially arranged with the flue unit 1 and connected to the inner wall of the flue unit 1 near the first connecting end. The joint of the flue units 1 of two adjacent concrete modules is radially opposite to the outer peripheral wall of the connecting ring 3. A gap is provided between the outer peripheral wall of the connecting ring 3 and the joint, and fireproof putty is provided in the gap.
[0034] In this embodiment, the connecting ring 3 is made of alloy steel and has a thickness of 4-6mm. To reduce the overall weight and ensure the load-bearing effect, the thickness of the connecting ring 3 is preferably 5mm. Specifically, the connecting ring 3 is a stepped ring.
[0035] In practical applications, the module body includes a top plate 4 and a bottom plate 5, both of which are fitted onto the flue unit 1. The top plate 4 and the flue unit 1, as well as the bottom plate 5 and the flue unit 1, are connected by reinforcing bars 6. A mortar layer 7 is also provided between the top plate 4 and the flue unit 1, and between the bottom plate 5 and the flue unit 1. To facilitate the injection of the mortar layer 7, a mortar inlet 51 and a mortar outlet 52 are provided on the bottom plate 5.
[0036] Example 2
[0037] This embodiment provides a modular building, which includes multiple concrete modules as described in Embodiment 1. The flue unit 1 in the multiple concrete modules is connected in sequence to form an exhaust shaft.
[0038] Because the protruding structure on the flue unit 1 can partially block the exhaust gas and prevent it from flowing out from the gap at the splice joint, and because there is also a compression layer 2 between the joints of the flue units 1 of the two adjacent concrete modules, gaps can be prevented at the joints, further preventing the leakage of exhaust gas in the flue unit 1.
