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 poor.

[0003] When constructing a concrete structural column connected to the foundation, steel bars are usually reserved at the top of the foundation after the foundation is poured. When constructing the structural column, the steel bars in the structural column and the steel bars reserved at the top of the foundation are tied and fixed before pouring the concrete of the structural column. This method is to pour concrete on site, which involves a lot of wet work, requires a support system to be set up on site, and has a long construction period. After the concrete is poured, the structural column and foundation cannot be disassembled and 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 column.

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

[0006] A connection node between a foundation and a structural column, comprising a foundation and a prefabricated column arranged above the foundation, wherein an anchor is pre-buried in the foundation, and the anchor comprises an anchor head extending out of the top surface of the foundation;

[0007] A slot is provided at one end of the prefabricated column connected to the foundation, and the slot includes an installation slot provided on the end face of the prefabricated column and a rotation slot provided inside the prefabricated column. The installation slot and the rotation slot are connected, and the anchor head can be inserted from the installation slot into the rotation slot, and after the prefabricated column is rotated, the anchor head cannot pass through the installation slot.

[0008] Furthermore, the anchoring member includes a column integrally formed with the anchoring head, wherein a portion of the column is pre-buried in the foundation and a portion extends out of an upper surface of the foundation, and a height of the extending portion is the same as a height of the mounting groove.

[0009] Furthermore, the height of the anchoring head is consistent with the height of the rotation groove.

[0010] Furthermore, the horizontal cross-section of the anchor piece and the horizontal cross-section of the mounting groove are both in the shape of long strips, and the horizontal cross-section of the rotating groove is in the shape of a circle or two sectors.

[0011] Furthermore, the cross-sectional area of ​​the anchor head gradually decreases in the direction away from the column, and the horizontal cross-sectional area of ​​the mounting groove is not less than the maximum cross-sectional area of ​​the anchor.

[0012] Furthermore, the prefabricated column includes a main column body and a connecting piece arranged at the end of the main column body, and the slot is opened at the end surface of the connecting piece away from the main column body.

[0013] Furthermore, the prefabricated column, foundation and side walls of the connector are all coplanar.

[0014] Furthermore, an enlarged head buried in the foundation is provided on a side of the column away from the anchoring head.

[0015] In summary, the present application includes at least one of the following beneficial effects:

[0016] 1. The present application provides a card slot on the end face of the prefabricated column and pre-buries an anchor in the foundation. When installing the prefabricated column, the anchor can be inserted into the card slot, and the prefabricated column can be rotated to achieve vertical limit between the prefabricated column and the foundation, so as to achieve stable installation between the prefabricated column and the foundation, and the prefabricated column can be removed from the foundation later;

[0017] 2. Since the slot is formed in the prefabricated column of the concrete structure, the manufacturing difficulty is relatively large. By arranging a connecting piece at the end of the prefabricated column, the slot can be arranged in the connecting piece, thereby reducing the manufacturing difficulty.

[0022] The following is combined with Figure 1-3 The present application is further described in detail, and the figure shows an example where no connecting piece is provided.

[0023] Example 1

[0024] A connection node between a foundation and a structural column disclosed in an embodiment of the present application, referring to Figures 1 to 3 A connection node between a foundation and a structural column includes a foundation 1 and a prefabricated column 2 installed above the foundation 1. In the embodiment of the present application, a square structural column is used as an example for explanation, but the cross-sectional form of the structural column is not limited to a square. An anchor 3 is pre-embedded in the foundation 1, and a slot 21 is provided on the end surface of the prefabricated column 2 facing the foundation 1.

[0025] Specifically, the anchor 3 includes an integrally formed column 32 and an anchor head 31, wherein the column 32 is partially located in the foundation 1 and partially extends out of the upper surface of the foundation 1, and the anchor head 31 is arranged at one end of the column 32 extending out of the foundation 1. In another preferred embodiment, an enlarged head 33 is further arranged at the end of the column 32 pre-buried in the foundation 1, and the enlarged head 33 is arranged to strengthen the anchoring strength of the anchor 3 and the column 32.

[0026] The slot 21 includes a side mounting slot 211 and a rotation slot 212 which are interconnected, and the mounting slot 211 is opened on the end face of the prefabricated column 2, and the rotation slot 212 is opened inside the prefabricated column 2; when the prefabricated column 2 is installed above the foundation 1, the anchor head 31 passes through the mounting slot 211 and is accommodated in the rotation slot 212.

[0027] Specifically, the height of the column 32 extending from the top of the foundation 1 is the same as the height of the installation groove 211, so that when the anchor head 31 is located in the rotation groove 212, the end face of the prefabricated column 2 and the end face of the foundation 1 abut against each other, so as to reduce the gap between the prefabricated column 2 and the foundation 1 after installation.

[0028] The horizontal cross-section of the anchor head 31 and the horizontal cross-section of the mounting groove 211 are both in the shape of long strips, and the length of the long side of the anchor head 31 is greater than the length of the short side of the mounting groove 211. The horizontal cross-section of the rotation groove 212 is circular or in the shape of two sectors. Of course, the horizontal cross-section of the rotation groove 212 is not limited to circular and sector-shaped, as long as the rotation groove 212 can provide a rotation space for the anchor head 31.

[0029] When the prefabricated column 2 is hoisted until the anchor head 31 passes through the installation groove 211 and is located in the rotation groove 212, the prefabricated column 2 can be rotated to rotate the slot 21 relative to the anchor 3, so that the long side of the anchor head 31 can intersect with the long side of the installation groove 211. At this time, when the prefabricated column 2 is hoisted upward, the anchor head 31 cannot be moved out of the installation groove 211, thereby realizing the vertical restriction of the prefabricated column 2.

[0030] In another embodiment, the height of the anchor head 31 is consistent with the height of the rotation groove 212, so that the upper and lower side walls of the anchor head 31 are respectively abutted against the upper and lower side walls of the rotation groove 212, thereby clamping the anchor 3 and the slot 21. On the one hand, it is convenient for the prefabricated column 2 to better transfer the vertical pressure to the foundation 1, and on the other hand, it can increase the friction between the prefabricated column 2 and the foundation 1, and reduce the rotation of the prefabricated column 2 relative to the foundation 1 under the action of external force after the prefabricated column 2 is installed in place.

[0031] In another preferred embodiment, the cross-sectional area of ​​the anchor head 31 gradually decreases in the direction away from the column body 32. As the cross-sectional area of ​​the anchor head 31 gradually decreases, the side wall of the anchor head 31 forms a slope. When installing the prefabricated column 2, since the top wall area of ​​the anchor head 31 is smaller, it is easier to align with the installation groove 211, and the slope of the side wall guides the falling of the prefabricated column 2, so that the anchor 3 can be more smoothly inserted into the prefabricated column 2.

[0032] In addition, the horizontal cross-sectional area of ​​the installation groove 211 is not less than the maximum cross-sectional area of ​​the anchor 3 , thereby enabling the anchor 3 to be more smoothly and quickly plugged into the installation groove 211 and enter the rotation groove 212 along the installation groove 211 .

[0033] Example 2

[0034] The difference between Example 2 and Example 1 is that the prefabricated column 2 includes a main column and a connector provided at one end of the main column for connecting to the foundation 1, and the slot 21 is provided at the end face of the connector away from the main column. The effect of the slot 21 on the structural strength of the prefabricated column 2 can be reduced by providing the connector. The slot 21 is directly provided in the prefabricated column 2, which is inconvenient to construct and manufacture. It is difficult to reserve the slot 21. The connector can be used to achieve more convenient manufacturing. The connector can be, but is not limited to, a steel structure, a ceramic structure, etc.

[0035] Preferably, the prefabricated columns 2, the foundation 1 and the side walls of the connecting members are all coplanar, thereby making the overall appearance of the vertical support structure smoother and providing a better visual effect.

[0036] The implementation principle of a connection node between a foundation and a structural column in an embodiment 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 a concrete building, a stable connection node can be formed at the connection between each component without grouting; at the same time, each concrete component can be prefabricated and processed in a factory and transported to the site for assembly and construction, and 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 a steel structure temporary building, and also has the living comfort of a concrete building.

[0037] 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.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
