Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a column base connection node structure. Background Technology

[0002] Container houses offer advantages such as convenient transportation, standardization, and modularity, and are widely used in large-scale construction projects, as well as in commercial, civilian, and military fields. For containers with high strength requirements, installation begins by connecting the steel columns around the container to a concrete foundation using column base plates. Then, concrete is poured into the gaps between the column base plates and the concrete foundation. Once the concrete has reached its strength and formed a floor, the container can be secured to the floor.

[0003] In existing technologies, since column base plates are typically flat two-dimensional components, for containers of the same size, the bottom elevations of the steel columns of adjacent containers are consistent, allowing them to be connected via flat column base plates. However, for containers of different sizes, the bottom of the containers has support beams. When adjacent containers have different sizes, the specifications of these support beams (support beam thickness) also differ. To ensure that the bottom surfaces of the two containers are flush after installation, the bottom elevations of the steel columns will be inconsistent. Therefore, flat column base plates cannot simultaneously connect the steel columns of two containers of different sizes, causing inconvenience during container house construction. Summary of the Invention

[0004] The purpose of this invention is to provide a column base connection node structure that can simultaneously connect two adjacent steel columns with different bottom elevations, thereby solving the problem of construction difficulties in container houses caused by the different bottom elevations of two adjacent steel columns in the prior art.

[0014] As preferred, a gasket is arranged between the limiting piece and the first connecting bottom plate and between the fastener and the first connecting bottom plate, and the connecting piece penetrates the gasket.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0044] Referring to Figures 1-3 The present embodiment provides a column foot connecting node structure which can simultaneously connect two adjacent steel columns with inconsistent bottom elevations, so as to solve the problem of difficult construction of container houses in the prior art due to inconsistent bottom elevations of two adjacent steel columns. The column foot connecting node structure comprises a concrete foundation 1, first and second steel columns 2 and 3 arranged adjacent to each other, and a column foot bottom plate 4.

[0045] The connecting piece 11 is embedded in the concrete foundation 1 and protrudes from the upper surface of the concrete foundation 1, the bottom of the first steel column 2 is located on a first plane, the bottom of the second steel column 3 is located on a second plane, and the first plane and the second plane are at different heights. The column base plate 4 comprises a first connecting bottom plate 41 and a second connecting bottom plate 42 which are connected and vertically spaced, and the first connecting bottom plate 41 and the second connecting bottom plate 42 are both fixed to the concrete foundation 1 through the connecting piece 11. The vertical distance between the first connecting bottom plate 41 and the second connecting bottom plate 42 is equal to the vertical distance between the first plane and the second plane, the first connecting bottom plate 41 can be connected with the bottom of the first steel column 2, and the second connecting bottom plate 42 can be connected with the bottom of the second steel column 3.

[0046] In this embodiment, as shown in Figure 5 , the first steel column 2 and the second steel column 3 can be steel columns of two adjacent containers of different specifications respectively (the dashed line in Figure 5 represents the plane on which the bottom surface of the container is located), and the height difference between the bottom of the first steel column 2 and the bottom of the second steel column 3 is the thickness difference of the bottom support beams 100 of the two containers. When installing two adjacent containers of different specifications, first, the first connecting bottom plate 41 and the second connecting bottom plate 42 are fixed to the concrete foundation 1 through the connecting piece 11, and then the bottom of the first steel column 2 is connected with the first connecting bottom plate 41 and the bottom of the second steel column 3 is connected with the second connecting bottom plate 42, so that the steel columns of the two adjacent containers of different specifications can be connected to one column base plate 4. Finally, concrete is poured in the gap between the first connecting bottom plate 41 and the concrete foundation 1 and in the gap between the second connecting bottom plate 42 and the concrete foundation 1, and after the concrete reaches the strength, a terrace is formed, so that the two adjacent containers of different specifications can be fixed on the terrace. Since the vertical distance between the first connecting bottom plate 41 and the second connecting bottom plate 42 is equal to the vertical distance between the first plane and the second plane, when the first steel column 2 and the second steel column 3 are connected with the first connecting bottom plate 41 and the second connecting bottom plate 42 respectively, the bottoms of the two adjacent containers of different specifications can be kept flush, meeting the installation requirements of the container house, thereby solving the problem of difficult construction of the container house caused by the inconsistent elevation of the bottoms of the steel columns of containers of different specifications in the prior art.

[0047] Further, a plurality of connecting pieces 11 are provided on the concrete foundation 1, and a plurality of through holes 411 corresponding to the plurality of connecting pieces 11 are provided on the first connecting bottom plate 41 and the second connecting bottom plate 42, and the connecting piece 11 can be arranged in the corresponding through hole 411. The plurality of connecting pieces 11 enable the first connecting bottom plate 41 and the second connecting bottom plate 42 to have multiple-point contact with the concrete foundation 1, thereby increasing the connection strength.

[0048] Alternatively, referring to Figure 4The column base plate 4 also includes a vertical plate 43, with its two ends connected to a first connecting base plate 41 and a second connecting base plate 42, respectively. Preferably, the vertical plate 43 is vertically connected to both the first connecting base plate 41 and the second connecting base plate 42, and the height of the vertical plate 43 is equal to the height difference between the first plane and the second plane. By selecting the vertical plate 43 to connect the first connecting base plate 41 and the second connecting base plate 42, the first connecting base plate 41, the vertical plate 43, and the second connecting base plate 42 form a stepped column base plate 4. The height of the vertical plate 43 is equal to the height difference between the first plane and the second plane (the difference in the bottom elevation of two adjacent steel columns), which can compensate for the difference in the bottom elevation of the first steel column 2 and the second steel column 3. This allows the stepped column base plate 4 to simultaneously connect two adjacent first steel columns 2 and second steel columns 3 with inconsistent bottom elevations.

[0049] Further, see Figure 4 The column base plate 4 also includes a first stiffening plate 44, with adjacent sides of the first stiffening plate 44 connected to the vertical plate 43 and the first connecting base plate 41, respectively. The first stiffening plate 44 increases the connection strength between the first connecting base plate 41 and the vertical plate 43, thereby improving the overall structural strength of the column base plate 4. Preferably, one first stiffening plate 44 is provided at each end and the middle of the vertical plate 43, with the three stiffening plates equally spaced to further improve the connection strength between the first connecting base plate 41 and the vertical plate 43. In other embodiments, multiple first stiffening plates 44 can be equally spaced along the length of the vertical plate 43. The spacing and number of the multiple first stiffening plates 44 are selected according to the support strength requirements of the column base plate 4, and are not limited to the spacing and number listed in this embodiment.

[0050] For example, in this embodiment, the first stiffening plate 44 is configured as an isosceles right triangle. The two right-angled sides of the first stiffening plate 44 are connected to the first connecting base plate 41 and the vertical plate 43, respectively. The length of the two right-angled sides is equal to the height of the vertical plate 43, and the thickness of the first stiffening plate 44 is the same as the thickness of the vertical plate 43. A first stiffening plate 44 is provided at each end of the vertical plate 43, and the first stiffening plates 44 are symmetrically arranged in the middle of the vertical plate 43 at a spacing of no more than 200mm.

[0051] In this embodiment, the first connecting base plate 41, the second connecting base plate 42, the vertical plate 43, and the first stiffening plate 44 are all made of steel plates, which are readily available and easy to process. Before installing two adjacent steel columns 2 and 3 with different bottom elevations, the dimensions of the column base plate 4 must first be determined: the dimensions of the first connecting base plate 41 and the second connecting base plate 42 are determined according to the specifications of the first steel column 2 and the second steel column 3. After cutting the steel plate into a suitable shape, holes are made according to the positioning and specifications of the connector 11 to obtain the first connecting base plate 41 and the second connecting base plate 42. At the same time, the height of the vertical plate 43 (the difference between the heights of the first plane and the second plane) is determined according to the difference in the bottom elevations of the first steel column 2 and the second steel column 3. The thickness of the vertical plate 43 is taken as the larger value of the thickness of the first connecting base plate 41 and the second connecting base plate 42. The first connecting base plate 41 and the second connecting base plate 42 are welded to the two ends of the vertical plate 43 respectively, and the first stiffening plate 44 is welded between the first connecting base plate 41 and the vertical plate 43 to obtain the column base plate 4. The welding method provides a stable connection, saves materials, and has high construction efficiency.

[0052] Optionally, such as Figure 3 As shown, the column base connection node structure also includes a limiting member 5. The limiting member 5 is adjustablely installed on the connector 11. Both the first connecting base plate 41 and the second connecting base plate 42 can be limited on the connector 11 by the limiting member 5. By adjusting the installation position of the limiting member 5 on the connector 11, the height of the first connecting base plate 41 and the second connecting base plate 42 relative to the concrete foundation 1 can be adjusted. By adjusting the height of the first connecting base plate 41 and the second connecting base plate 42 relative to the concrete foundation 1 on the connector 11 by the limiting member 5, the elevation and levelness of the first connecting base plate 41 and the second connecting base plate 42 can be adjusted, thereby adjusting the bottom elevation and verticality of the first steel column 2 and the second steel column 3. The level first connecting base plate 41 and the second connecting base plate 42 can more stably support the first steel column 2 and the second steel column 3, so that the first steel column 2 and the second steel column 3 after installation are perpendicular to the upper surface of the concrete foundation 1, ensuring the stability of the first steel column 2 and the second steel column 3 and meeting the construction requirements.

[0053] Furthermore, the column base connection node structure also includes a fastener 6, which is sleeved on the connector 11 and located on the side of the first connecting base plate 41 and the second connecting base plate 42 facing away from the limiting member 5. The fastener 6 can press the first connecting base plate 41 or the second connecting base plate 42 tightly onto the limiting member 5. The cooperation between the limiting member 5 and the fastener 6 can fix the first connecting base plate 41 and the second connecting base plate 42 to the concrete foundation 1 through the connector 11, thereby stably fixing the first steel column 2 and the second steel column 3 to the concrete foundation 1. Preferably, each connector 11 is provided with two fasteners 6, namely fastener one and fastener two. Fastener one and the limiting member 5 cooperate to limit the first connecting base plate 41 and the second connecting base plate 42 on the concrete foundation 1 through the connector 11. Fastener two is installed on the side of fastener one that is away from the first connecting base plate 41 and the second connecting base plate 42, and is pressed against fastener one to prevent fastener one from loosening under force during construction and to increase the strength of the connection.

[0054] Optionally, see Figure 1 The connector 11 includes a threaded rod 111. One end of the threaded rod 111 is embedded in the concrete foundation 1 and has a hook 112. The end of the threaded rod 111 extending out of the concrete foundation 1 has an external thread. The limiting member 5 and the fastener 6 are both screwed onto the threaded rod 111 via the external thread. The hook 112 increases the friction between the connector 11 and the concrete foundation 1, improving the connection strength and preventing the connector 11 from being pulled out during construction. The limiting member 5 and the fastener 6 are both screwed onto the threaded rod 111 via the external thread, facilitating easy assembly and disassembly and ensuring a stable connection. In this embodiment, the connector 11 is an L-shaped anchor bolt, and the limiting member 5 and the fastener 6 are nuts, making them readily available and adaptable.

[0055] Furthermore, gaskets 7 are provided between the limiting member 5 and the first connecting base plate 41, and between the fastener 6 and the first connecting base plate 41, with the connector 11 passing through the gaskets 7. Similarly, gaskets 7 are provided between the limiting member 5 and the second connecting base plate 42, and between the fastener 6 and the second connecting base plate 42, with the connector 11 passing through the gaskets 7. The gaskets 7 increase the contact area between the limiting member 5 and the fastener 6 and the first connecting base plate 41 and the second connecting base plate 42, increasing the connection strength between them and preventing loosening. At the same time, the gaskets 7 reduce the pressure exerted by the limiting member 5 and the fastener 6 on the first connecting base plate 41 and the second connecting base plate 42, protecting the parts and threads.

[0056] Optionally, see Figure 2Multiple second stiffening plates 8 are provided on the first connecting base plate 41 along the circumference of the first steel column 2 and on the second connecting base plate 42 along the circumference of the second steel column 3. Each second stiffening plate 8 is connected to the corresponding first steel column 2 or second steel column 3. By connecting the first steel column 2 with the first connecting base plate 41 and the second steel column 3 with the second connecting base plate 42 through the second stiffening plates 8, the connection strength between the first steel column 2 and the first connecting base plate 41 and the second steel column 3 and the second connecting base plate 42 can be increased. Preferably, the second stiffening plates 8 are also made of steel plates and welded between the first steel column 2 and the first connecting base plate 41 and the second steel column 3 and the second connecting base plate 42.

[0057] Further, see Figure 6 The column base connection node structure also includes a concrete filling layer 9, which fills the gaps between the first connecting base plate 41 and the concrete foundation 1, as well as the gaps between the second connecting base plate 42 and the concrete foundation 1. After the elevations of the first connecting base plate 41 and the second connecting base plate 42 relative to the concrete foundation 1, and the verticality of the first steel column 2 and the second steel column 3 are adjusted, the concrete filling layer 9 is filled into both the gaps between the first connecting base plate 41 and the concrete foundation 1 and the gaps between the second connecting base plate 42 and the concrete foundation 1, thereby fixing the first connecting base plate 41 and the second connecting base plate 42 to the concrete foundation 1 and increasing the stability of the column base connection node structure. Preferably, the concrete filling layer 9 is made of fine aggregate concrete with a strength grade one level higher than that of the concrete foundation 1. Fine aggregate concrete has better compaction and does not require vibration during production, improving construction efficiency.

[0058] See Figure 5 and Figure 6 When installing two adjacent containers of different specifications using the column base connection node structure provided in this embodiment, the following steps are included:

[0059] Step 1: Screw the limiting part 5 onto the screw part 111 of the connecting part 11 (a certain gap is reserved between the limiting part 5 and the upper surface of the concrete foundation 1 to allow for the operation space of adjusting the limiting part 5. In this embodiment, the gap between the limiting part 5 that cooperates with the second connecting base plate 42 and the concrete foundation 1 is set to 50mm).

[0060] The second step is to roughly adjust the height of the limiting piece 5 on the connecting piece 11 to adjust the bottom elevation and verticality of the first steel column 2 and the second steel column 3, and to put the shim 7 through the connecting piece 11 and place it on the limiting piece 5.

[0061] Third step: Match the multiple through holes 411 on the first connecting base plate 41 and the second connecting base plate 42 with the multiple connectors 11 one by one, so that the first connecting base plate 41 and the second connecting base plate 42 are inserted through the connectors 11 and placed on the gasket 7.

[0062] Fourth step: Weld the bottom of the first steel column 2 and the bottom of the second steel column 3 to the first connecting base plate 41 and the second connecting base plate 42 respectively, and weld the second stiffening plate 8 between the first steel column 2 and the first connecting base plate 41 and between the second steel column 3 and the second connecting base plate 42.

[0063] Step 5: Place a gasket 7 on the side of the first connecting base plate 41 and the second connecting base plate 42 facing away from the limiting member 5 on each connector 11, and screw the fastener 1 onto the connector 11 (at this time, the fastener 1 is not tightened).

[0064] Step 6: Fine-tune the installation height of the limiting piece 5 on the connector 11 to precisely adjust the bottom elevation and verticality of the first steel column 2 and the second steel column 3;

[0065] Step 7: Tighten fastener one and screw fastener two onto connector 11 so that fastener two abuts against fastener one;

[0066] Step 8: Pour concrete filling layer 9 into the gaps between the first connecting base plate 41 and the concrete foundation 1, and between the second connecting base plate 42 and the concrete foundation 1. After the concrete reaches its strength and forms a floor, the first steel column 2 and the second steel column 3 can be fixed on the floor, while ensuring that the bottom surfaces of the two containers of different specifications are flush (e.g., Figure 5 (As shown).

[0067] Optionally, the fourth step can be moved before the first step. Specifically, after the dimensions of the column base plate 4 are determined, the bottom of the first steel column 2 and the bottom of the second steel column 3 are welded to the first connecting base plate 41 and the second connecting base plate 42 respectively, and the second stiffening plate 8 is welded between the first steel column 2 and the first connecting base plate 41 and between the second steel column 3 and the second connecting base plate 42.

[0068] It should be noted that the first steel column 2 and the second steel column 3 can also be the steel column of the container and the steel column of the steel structure adjacent to the container, respectively. For example... Figure 7 As shown, when the container is installed adjacent to the steel structure, after the column base plate 4 is installed, materials are needed to bury the support beam 100 at the bottom of the container underground. At this time, in order to ensure the surface is flat after burying... Figure 7 The dotted line in the diagram represents the plane where the bottom of the container is located. The second stiffening plates 8 around the steel columns of the adjacent steel structure need to be buried underground together with the support beams 100. However, the height of the second stiffening plates 8 is often different from the thickness of the support beams 100, and to meet the usage requirements of the container, the backfill material cannot be higher than the bottom of the container. Therefore, to ensure a flat final ground surface, the bottom elevations of the steel columns of adjacent steel structures and the steel columns of the container will be inconsistent. Therefore, the column base connection node structure provided in this embodiment can also be used for installation, improving construction efficiency.

[0069] Similarly, as Figure 8 As shown, the first steel column 2 and the second steel column 3 can also be steel columns of two adjacent steel structures of different specifications, not limited to the steel columns of containers. When it is necessary to ensure that the tops of the second stiffening plates 8 on the steel columns of two adjacent steel structures of different specifications are in the same height plane (such as... Figure 8 The plane shown by the dashed line can also be installed using the column base connection node structure provided in this embodiment.

[0070] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
