Description

Technical Field

[0001] The utility model belongs to the field of container building construction, and in particular relates to a prefabricated foundation structure for connecting container modules. Background Art

[0002] Container buildings are a type of building that uses old or newly built containers as building materials. This type of building method has attracted more and more attention and applications due to its environmental protection, economy and rapid construction. However, current container buildings generally do not have a foundation base. Such buildings will be in contact with the bottom surface for a long time, which will cause corrosion to the bottom surface of the building and affect its service life. Therefore, it is necessary to set a concrete foundation at the bottom of the container building. However, in some areas with higher latitudes, the concrete foundation cannot be constructed due to the low outdoor temperature, so there is an urgent need to provide a prefabricated foundation structure. Utility Model Content

[0003] The utility model aims to solve the deficiencies in the prior art and provide a prefabricated basic structure for connecting container buildings.

[0004] The specific technical solutions adopted by this utility model are as follows:

[0005] The utility model provides a prefabricated foundation structure for connecting container buildings, comprising a prefabricated foundation, an adjustment block, a first connecting plate, a second connecting plate and a top connecting piece; the prefabricated foundation is precast in a factory, and a plurality of ground anchor bolts are pre-buried on the top of the prefabricated foundation;

[0006] The first connecting plate and the second connecting plate are both provided with holes for passing the anchor bolts; the second connecting plate is fixed to the top of the prefabricated foundation after passing through the anchor bolts; a plurality of adjustment blocks of equal height are arranged on the second connecting plate, and the first connecting plate is placed on the adjustment blocks after passing through the anchor bolts; the first connecting plate is fixed to the adjustment blocks by fasteners passing through the tops of the anchor bolts, so that a post-casting layer for secondary pouring is formed between the first connecting plate and the second connecting plate; a top connecting piece for connecting to the container building above is fixed on the first connecting plate.

[0007] Preferably, the adjusting block is a wedge-shaped wooden block or a square timber, and elevation control during construction is achieved by adjusting the heights of the different adjusting blocks.

[0008] Preferably, the first connecting plate is made of steel plate.

[0009] Preferably, the second connecting plate is made of steel plate.

[0010] Preferably, the fastener is a double nut that matches the anchor bolt.

[0011] Preferably, a gasket for dispersing pressure is provided between the fastener and the first connecting plate.

[0012] Preferably, the top connecting member includes a top plate, a bottom plate and cross stiffening ribs vertically fixed between the top plate and the bottom plate.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] (1) The formwork and pouring of the prefabricated foundation provided by the utility model are completed in the factory. Compared with on-site concrete pouring, the quality of the prefabricated foundation is easier to control. Since it is completed in the factory (indoors), it can be processed smoothly even in some seasons with low temperatures. While improving the on-site construction speed, it also avoids the situation where concrete pouring cannot be carried out due to seasonal reasons.

[0018] (2) The utility model uses wedge-shaped wooden blocks as adjustment blocks, which can effectively control the elevation of the column bottoms during the construction process, so that all column bottoms are on the same horizontal plane, thereby improving the construction accuracy of the building.

[0019] (3) All on-site connections are made with bolts, without welding. All precision control is focused on the hole locations, and the holes are drilled in the factory, which effectively improves construction accuracy and ensures building quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below. The technical features in each embodiment of the utility model can be combined accordingly without conflicting with each other.

[0024] In the description of the present utility model, it should be understood that the terms "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0025] like Figure 1 As shown, as a preferred embodiment of the present utility model, this embodiment provides a prefabricated foundation structure for connecting container buildings, including a prefabricated foundation 1, an adjustment block 3, a first connecting plate 4, a second connecting plate 5 and a top connecting member 7.

[0026] In order to solve the problem that the outdoor temperature is too low in some areas with high latitudes, the concrete foundation cannot be constructed. The prefabricated foundation 1 in the utility model is precast in the factory, and a plurality of ground anchor bolts 2 are pre-buried on the top of the prefabricated foundation 1.

[0027] Anchor bolts, also known as foundation bolts or anchor bolts, are key components used to fix steel structures to concrete foundations. According to different application needs and design requirements, anchor bolts can be used in a variety of models and specifications. Technicians in this field can choose to use J-type anchor bolts, L-type anchor bolts or straight anchor bolts according to actual working conditions.

[0028] In the structure provided by the utility model, holes for passing the anchor bolts 2 are formed on the first connecting plate 4 and the second connecting plate 5. The distribution positions of the holes are consistent with the distribution positions of the anchor bolts 2 on the prefabricated foundation 1.

[0029] In the structure provided by the utility model, the second connecting plate 5 is fixed on the top of the prefabricated foundation 1 after passing through the anchor bolt 2. A plurality of adjusting blocks 3 of equal height are arranged on the second connecting plate 5, and the first connecting plate 4 is placed on the adjusting block 3 after passing through the anchor bolt 2. The first connecting plate 4 is fixed on the adjusting block 3 by passing through the top of the anchor bolt 2 through the fastener 6, so that a post-casting layer 8 for secondary casting is formed between the first connecting plate 4 and the second connecting plate 5.

[0030] In this embodiment, the first connecting plate 4 and the second connecting plate 5 are both made of steel plates, and the first connecting plate 4 and the second connecting plate 5 are of equal size. The fastener 6 is a double nut that matches the anchor bolt 2. In order to prevent the double nut from being directly pressed on the first connecting plate 4 and causing damage or deformation, a gasket can be provided between the fastener 6 and the first connecting plate 4. The gasket can also increase friction to prevent the double nut from loosening under vibration or other external forces, and the gasket can also play a filling role to ensure close contact between the double nut and the first connecting plate 4.

[0031] like Figure 1 As shown, in this embodiment, the adjusting block 3 is a wedge-shaped wooden block. It should be noted that those skilled in the art can use different height adjusting blocks 3 to adjust the height of the post-casting layer 8 for secondary pouring between the first connecting plate 4 and the second connecting plate 5 to achieve elevation control during construction.

[0032] In the structure provided by the utility model, a top connector 7 for connecting to the upper container building is fixed on the first connecting plate 4. The top connector 7 includes a top plate, a bottom plate, and a cross stiffening rib vertically fixed between the top plate and the bottom plate. The bottom plate of the top connector 7 is fixed to the first connecting plate 4 by welding, and a plurality of bolt holes for connection are provided on the top plate of the top connector 7.

[0033] The construction process of the prefabricated foundation structure is described below:

[0034] During the on-site installation process, the prefabricated foundation 1 is first buried in the pre-dug foundation pit, and the second connecting plate 5 has been fixed to the top of the prefabricated foundation 1 through the anchor bolts 2. The bottom plate of the top connecting member 7 is fixed to the first connecting plate 4 by welding.

[0035] Insert the combined component of the top connecting member 7 and the first connecting plate 4 into the anchor bolt 2. Adjust the column bottom to the corresponding elevation by adjusting the block 3 on site and then screw on the double nut for fixing.

[0036] After the elevation adjustment is completed, the corner connector of the upper container building can be connected to the top plate of the top connector 7 of the prefabricated foundation. The uncast part between the first connecting plate 4 and the second connecting plate 5, i.e., the post-casting layer 8, can be cast for the second time when the temperature is suitable.

[0037] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
