Description

Technical Field

[0001] The present application relates to the technical field of prefabricated buildings, and in particular to a connection node between a foundation and a structural column. Background Art

[0002] At present, in order to meet the needs of production and manufacturing, there are a large number of temporary buildings. Temporary building structures are usually assembled from container structures or overlapped with color steel plates. They have poor sound insulation, weak structural bearing capacity and are prone to rust. Compared with concrete buildings, the living experience is worse.

[0003] When constructing concrete columns connected to foundations, rebar is typically reserved at the top of the foundation after the foundation is poured. During the construction of the columns, the rebar within the columns is tied to the pre-rebar at the top of the foundation before the concrete for the columns is poured. This method involves pouring concrete on-site, which involves extensive wet work and requires an on-site support system. This results in a long construction period, and after the concrete is poured, the columns and foundation cannot be disassembled or reused. Utility Model Content

[0004] In order to improve the problem that foundations and structural columns are difficult to disassemble and reuse, the present application provides a connection node between the foundation and the structural columns.

[0005] This application provides a connection node between a foundation and a structural column, which adopts the following technical solution:

[0007] A plug-in component is pre-buried at one end of the column connected to the foundation, and the plug-in component is plugged into a plurality of installation slots at the same time.

[0008] Furthermore, the anchoring member further includes a first embedded member and a connecting plate, wherein the first embedded member is partially embedded in the foundation, and the connecting plate is spaced apart from the foundation surface.

[0009] Furthermore, the connector includes a second embedded part, a plate and a plug connector fixed in sequence, the second embedded part is embedded in the column, and the plug connector is used to be plugged into the installation groove.

[0010] Furthermore, the surface of the pasting board is pasted to the end surface of the column.

[0011] Furthermore, the height of the plug connector is consistent with the depth of the installation slot.

[0012] Furthermore, a plurality of anchoring nails are fixed on the plate, and the anchoring nails are pre-buried in the column.

[0013] Furthermore, the first embedded part includes a first vertical plate and a second vertical plate, and the surface of the first vertical plate intersects with the surface of the second vertical plate.

[0014] Furthermore, the second embedded part includes a third vertical plate and a fourth vertical plate, and the surface of the third vertical plate intersects with the surface of the fourth vertical plate.

[0015] Furthermore, the width of the mounting groove gradually narrows from the center of the anchor head to the edge, and the shape of the plug connector matches the shape of the mounting groove.

[0016] Furthermore, the plug connector includes a center key and a plurality of side plug keys arranged around the center key, and the length of the center key is longer than the length of the side plug keys;

[0017] The installation slot includes a central slot and a plurality of edge slots. The central key is inserted into the central slot, and the plurality of edge insertion keys are inserted into the plurality of edge slots in a one-to-one correspondence.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] Example 1

[0029] The connection node between the foundation and the structural column disclosed in Example 1 of the present application is as follows: Figure 1 and Figure 2 A connection node between a foundation and a structural column includes a foundation 1 and a column 2 installed above the foundation 1. An anchor 3 is pre-embedded at the top of the foundation 1, and a connector 4 is pre-embedded at the end of the column 2. When the column 2 is installed above the foundation 1, the connector 4 is inserted into the anchor 3 to realize the installation and connection between the foundation 1 and the column 2.

[0030] The anchor 3 includes an anchor head 31 and a first embedded part 32. In one embodiment, the first embedded part 32 is entirely embedded in the foundation 1, with the anchor head 31 abutting the top of the foundation 1. In another embodiment, the first embedded part 32 is partially embedded in the foundation 1 and partially extends out of the foundation 1, such that the anchor head 31 is spaced apart from the top surface of the foundation 1. If the anchor head 31 is spaced apart from the top surface of the foundation 1, a post-cast section is formed between the anchor head 31 and the foundation 1. After the column 2 is installed above the foundation 1, the post-cast section is cast, which can improve the connection stability between the anchor 3 and the foundation 1.

[0031] In another preferred embodiment, the anchor 3 further includes a connecting plate 33. The first embedded part 32 and the anchor head 31 are respectively fixed to either side of the connecting plate 33. The connecting plate 33 allows the anchor head 31 and the first embedded part 32 to form a stable integral structure. If the first embedded part 32 is fully embedded in the foundation 1, the connecting plate 33 is in contact with the top surface of the foundation 1. If the first embedded part 32 is partially embedded in the foundation 1, the connecting plate 33 is spaced apart and parallel to the top surface of the foundation 1.

[0032] In one embodiment, the first embedded part 32 includes an integrally formed first vertical plate 321 and a second vertical plate 322, and the surfaces of the first vertical plate 321 and the second vertical plate 322 are cross-arranged, and preferably the surfaces of the first vertical plate 321 and the second vertical plate 322 are perpendicular. The cross-arrangement of the first vertical plate 321 and the second vertical plate 322 makes the overall strength of the first embedded part 32 stronger, and the ability of the first embedded part 32 to resist bending moment and torque is better. It should be noted that the shape of the first embedded part 32 is not limited to the shape disclosed in this embodiment. Under the premise of satisfying the embedded stability of the anchor 3 and the connection strength between the anchor 3 and the foundation 1 being able to resist external loads, the first embedded part 32 can also be other shapes, such as a plurality of vertical plates spaced around the connecting plate 33, or a plurality of vertical plates fixed on the connecting plate 33 in parallel and at intervals.

[0033] In the embodiment of the present application, the cross-section of the anchor head 31 is rectangular as an example for illustration. Each side wall of the anchor head 31 is provided with a mounting groove 311 in the box. The mounting groove 311 passes through the top wall and side wall of the anchor head 31. The mounting groove 311 is provided for the connector 4 to be plugged in.

[0034] The plug connector 4 includes a plug connector 43 and a second embedded part 41. The second embedded part 41 is embedded in the foundation 1. The plug connector 43 extends from the end face of the column 2. The shape of the plug connector 43 matches the shape of the multiple mounting slots 311. For example, in the embodiment of the present application, the plug connector 43 includes four plug keys that match the shape of the mounting slots 311. Because multiple mounting slots 311 are provided around the anchor head 31, the anchor head 31 can limit the displacement of the plug connector 4 in multiple directions, thereby improving the installation strength of the connection between the column 2 and the foundation 1. When installing the column 2, the plug connector 43 only needs to be inserted into the mounting slot 311 to complete the installation of the column 2. This not only makes the installation and construction of the column 2 convenient and quick, but also makes the column 2 easy to disassemble, allowing for multiple uses.

[0035] It should be noted that the height of the plug connector 43 is consistent with the depth of the mounting groove 311, so as to improve the connection strength between the plug connector 43 and the anchor head 31 as much as possible, as well as the strength against external loads.

[0036] In one embodiment, the width of the mounting groove 311 gradually narrows from the center of the anchor head 31 to the edge, and the shape of the plug connector 43 is adaptively adjusted to match the shape of the mounting groove 311. Setting an inclined surface for the mounting groove 311 can improve the fit between the plug connector 43 and the side wall of the mounting groove 311.

[0037] In one embodiment, the connector 4 further includes a plate 42, with the second embedded component 41 and the plug connector 43 respectively fixed to either side of the plate 42. When the connector 4 is embedded in the column 2, the plate 42 is in contact with the end face of the column 2. The plate 42 not only allows the second embedded component 41 and the plug connector 43 to form a stable whole, but also protects the end face of the column 2 from damage due to impact, thereby facilitating repeated disassembly and reuse of the column 2.

[0038] In one embodiment, a plurality of anchoring nails 44 are fixed to the plate 42. When the connector 4 is embedded in the column 2, the plurality of anchoring nails 44 are embedded in the column 2. The anchoring nails 44 can assist the second embedded part 41 to strengthen the connection between the connector 4 and the column 2, and enhance the strength of the connection between the connector 4 and the column 2 to resist bending and torque.

[0039] Furthermore, the second embedded part 41 includes a third vertical plate 411 and a fourth vertical plate 412, with the surfaces of the third vertical plate 411 and the fourth vertical plate 412 arranged crosswise, preferably perpendicularly. The design concept of the second embedded part 41 is consistent with the design concept of the first embedded part 32. It should also be noted that the shape of the second embedded part 41 is not limited to the shape disclosed in this embodiment. The second embedded part 41 can also have other shapes, provided that the embedded stability of the connector 4 is met and the connection strength between the connector 4 and the column 2 can withstand external loads.

[0040] Example 2

[0041] The difference between Example 2 and Example 1 is that, Figure 3 and Figure 4 The plug connector 43 includes a center key 431 and a plurality of side plug keys 432 arranged around the center key 431. The length of the center key 431 is longer than the length of the side plug keys 432. The mounting groove 311 includes a center groove 312 and a plurality of edge grooves 313. The center key 431 is plugged into the center groove 312, and the plurality of side plug keys 432 are plugged into the plurality of edge grooves 313 in a one-to-one correspondence. It should be noted that the depth and shape of the center groove 312 match those of the center key 431, and the depth and shape of the edge groove 313 match those of the side plug keys 4. The simultaneous provision of the center key 431 and the side plug keys 432 can improve the connection strength between the foundation 1 and the column 2, making the connection between the column 2 and the foundation 1 more resistant to external loads.

[0042] The implementation principle of the connection node between the foundation and the structural column of the present application is as follows: the core concept of the connection node design of the present application is to combine the traditional mortise and tenon structure assembly concept into concrete buildings, so that when forming the concrete building, a stable connection node can be formed at the connection of each component without grouting; at the same time, each concrete component can be prefabricated and processed in the factory and transported to the site for assembly and construction. The components can be dismantled, replaced and reused, forming a concrete temporary building construction system, which has the convenience of quick installation and disassembly of steel structure temporary buildings, and also has the living comfort of concrete buildings.

[0043] In addition, when the connection nodes of this application are constructed, there is no wet operation on site, which is clean and environmentally friendly, reducing pollution to the environment.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
