[0049] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application embodiments can be implemented without one or more of these details. In other examples, some technical features well known in the art are not described to avoid confusion with the present application embodiments.

[0052] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.
[0053] Unless otherwise stated, numerical ranges herein include not only the entire range between its two endpoints but also the several sub-ranges contained therein.
[0054] Figure 1 and Figure 2 A building module according to the present application is shown, comprising a concrete member 100 and at least four frames 110. The concrete member 100 is at least partially made of concrete comprising two aggregates of different bulk densities. The frames 110 have cavities therein, which are isolated from the outside of the frames 110.
[0055] The concrete component 100 includes at least four surfaces 101, each of which corresponds to at least four frames 110. The frames 110 are at least partially embedded in the corresponding surfaces 101, so that the concrete component has a bulk density of 1300 kg / m 3 Up to 1550kg / m 3 .
[0056] According to the building module of the present application, the use of concrete with two aggregate configurations having different bulk densities can reduce the mass of the concrete member 100 and ensure the compressive strength of the concrete member 100. In addition, the use of a frame 110 having a cavity built into the concrete member 100 can enhance the strength and stability of the building module. At the same time, because the cavity is isolated from the exterior of the frame 110, concrete cannot enter the frame 110, which also helps to reduce the weight of the building module, thereby reducing the cost of hoisting and transportation of the building module.
[0057] Reference Figure 1 In the specific embodiment of the present application, the concrete component 100 of the building module takes six faces 101 as an example. Correspondingly, the building module includes six frames 110, and the six frames 110 correspond one-to-one to the six faces 101. In other words, the building module according to the specific embodiment of the present application is constructed as a rectangular parallelepiped structure.
[0058] If the frame 110 is not included in the concrete member 100, the bulk density of the concrete member 100 is 1650 kg / m 3 Up to 1950kg / m 3 Since the frame 110 is at least partially embedded in the surface 101 corresponding to the concrete member 100, the bulk density of the frame 110 can be controlled at 1300 kg / m 3 Up to 1550kg / m 3, which helps to reduce the weight of building modules and reduce the lifting and transportation costs of building modules.
[0059] Optionally, Figure 1 Taking the surface body 101 on the right side of the building module as an example, the surface body 101 has a first edge 103 and a second edge 104. The first edge 103 extends in a first direction (taking the surface body 101 as an example, the first direction is the length direction D1 of the building module), and the second edge 104 extends in a second direction (taking the surface body 101 as an example, the second direction is the height direction D3 of the building module). The first direction is perpendicular to the second direction.
[0060] Combine Figure 2 As shown, the frame 110 includes at least two first beams 111 and at least one second beam 112 (corresponding to Figure 1 In the example of frame 110 within body 101, frame 110 includes ten second beams 112. First beams 111 and second beams 112 are arranged at a 90° angle and connected together. First beams 111 of frame 110 within body 101 extend along a first direction, while second beams 112 extend along a second direction. Second beams 112 are arranged between first beams 111.
[0061] Through the above arrangement, the corresponding frame 110 within the body 101 extends in both the first and second directions of the body 101, thereby providing good support for the body 101. Furthermore, the second beams 112 are arranged between the two first beams 111, and the second beams 112 are spaced apart along the first direction, so that the second beams 112 effectively support the first beams 111 at all positions along the first direction. This further enhances the structural stability of the frame 110, increases its structural strength, and ensures that the building module has good compressive resistance.
[0062] Optionally, at least one of the first beam 111 and the second beam 112 can be configured to have a hollow structure, forming a cavity, thereby facilitating weight reduction of the frame 110 and the building modules. In particular, both the first beam 111 and the second beam 112 can be configured to have a hollow structure, with the hollow structure of the first beam 111 communicating with the hollow structure of the second beam 112, further reducing the weight of the frame 110 and the building modules.
[0063] Reference Figure 2 Alternatively, the cross-sections of the first beam 111 and the second beam 112 may be rectangular. In other words, the first beam 111 and the second beam 112 may be made of square tubes, which provide a stable structure and low manufacturing cost. Alternatively, the cross-sections of the first beam 111 and the second beam 112 may be circular. In other words, the first beam 111 and the second beam 112 may be made of round tubes, which provide a stable structure and low manufacturing cost.
[0064] Reference Figure 1 At least one face 101 of the concrete component 100 has a door or window opening 102. In this embodiment, the face 101 located on the front side of the building module along the length direction D1 of the building module has the door or window opening 102. In the projection of the building module perpendicular to the door or window opening 102, along the width direction D2 of the building module, the door or window opening 102 is located between two second beams 112 of the frame 110 within the face 101. This provides support from the second beams 112 on both sides of the door or window opening 102, making the door or window opening 102 relatively stable.
[0065] Optionally, for the frame 110 in the surface body 101 having the door and window holes 102, the number and length of the first beams 111 and the second beams 112 can be adjusted according to actual needs. Figure 2 The frame 110 includes three second beams 112, and the lower first beam 111 of the frame 110 is connected to two of the second beams 112. The second beam 112 not connected to the lower first beam 111 is arranged on one side of the door and window hole 102, so that the height of the bottom edge of the door and window hole 102 will not be affected by the lower first beam 111.
[0066] Optionally, the material of the concrete component 100 includes a first aggregate and a second aggregate, and the bulk density of the first aggregate is less than that of the second aggregate, so that the weight of the concrete component 100 can be reduced by adjusting the ratio of the first aggregate and the second aggregate. In detail, the bulk density of the first aggregate is 400 kg / m 3 Up to 800kg / m 3 The second aggregate can be ordinary crushed stone aggregate. The volume ratio of the first aggregate to the second aggregate is 4:1. By mixing, the cement content of the concrete component 100 can be controlled at 490 kg / m 3 Up to 515kg / m 3 , which can improve the compressive performance of the concrete component 100 and also reduce the weight of the concrete component 100.
[0067] Optionally, the slump of the concrete of the concrete component 100 is 185 mm to 195 mm, and the structural strength of the concrete component 100 made of concrete is ensured when the first aggregate (with a smaller bulk density) is used.
[0068] The present application also provides a box-type building, which includes the above-mentioned building modules. The box-type building according to the present application uses lightweight building modules, which can reduce the hoisting cost and transportation cost of the building modules, thereby helping to reduce the construction cost of the box-type building.
[0069] Optionally, the box-type building further includes a pile foundation, in which a steel cage is provided, and the concrete member 100 is connected to the pile foundation, wherein the steel cage at least partially extends into the concrete member 100 and is connected to the frame 110, thereby enabling the frame 110 of the building module to be connected to the steel cage of the pile foundation, which is beneficial to improving the toughness of the box-type building and also improving the connection strength between the concrete member 100 and the pile foundation.
[0070] The present application also provides a method for manufacturing a building module, comprising the steps of:
[0071] S1. Prepare a frame 110. A cavity is provided in the frame 110. The cavity is isolated from the outside of the frame 110. The frame 110 includes a first beam 111 and a second beam 112. The first beam 111 and the second beam 112 are arranged at an angle and connected together.
[0072] S2. Prepare concrete by using the first aggregate and the second aggregate to mix the concrete. The bulk density of the first aggregate is less than that of the second aggregate, and the bulk density of the mixed concrete is 1650 kg / m 3 Up to 1950kg / m 3 ;

[0076] S6, pouring concrete into the mold to form the concrete component 100;
[0077] S7. After curing the concrete, the mold is removed to obtain the building module.
[0078] According to the manufacturing method of the building module of the present application, the manufactured building module is light in weight, which helps to reduce the hoisting cost and transportation cost of the building module.
[0079] In addition, the manufacturing method of the building module is simple to operate, has low manufacturing cost, and is easy to complete the construction of the building module at the construction site.
[0080] Optionally, in step S2, before using the first aggregate and the second aggregate to prepare concrete, the first aggregate needs to be tested. Specifically, the apparent density of the first aggregate is 900 kg / m 3 Up to 1200kg / m 3 The 1h water absorption rate of the first aggregate is less than 10%, and the cylinder compressive strength of the coarse aggregate of the first aggregate should be greater than 2Mpa, thereby ensuring that the concrete component 100 made of the configured concrete has sufficient compressive performance, and is reduced by about 35% compared with the existing concrete component 100.
[0081] Optionally, in step S2, the slump of the concrete is configured to be 185 mm to 195 mm. When the first aggregate (with a smaller bulk density) is used, the structural strength of the concrete member 100 made of the concrete can be ensured.
[0082] Optionally, a steel cage is prepared in step S3. In step S4, the frame 110 and the steel cage are installed in the mold, and the frame 110 is connected to the steel cage, so that the concrete components 100 of the building module are connected to the pile foundation.
[0083] Optionally, in step S6 , integral casting may be performed, or casting may be performed sequentially according to the surface body 101 .
[0084] Specifically, refer to Figure 3 In step S6, the frame 110 and concrete are poured together using a mold to form a split plate 106, with steel bars 107 reserved at the edge of the split plate 106. Figure 4 and Figure 5 As shown, each split plate 106 is fixed together by a reserved steel bar 107 and connected together by post-cast concrete 108, so that each surface body 101 is cast as a whole to obtain a building module.
