Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, and in particular to a connection node between a prefabricated column and a foundation. 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] Based on the above description, the utility model provides a connection node between a prefabricated column and a foundation to solve the problem that the structural column is difficult to disassemble and reuse from the foundation.

[0005] The utility model provides a technical solution to the above-mentioned technical problems as follows: a connection node between a prefabricated column and a foundation, comprising a foundation and a column body, wherein a threaded sleeve is pre-embedded in one of the components of the foundation and the column body, and a connecting screw is pre-embedded in the corresponding other component, and when the column body is installed above the foundation, the connecting screw is threadedly connected in the threaded sleeve.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, an enlarged head is provided at one end of the connecting screw located at the base or within the column.

[0008] Furthermore, one end of the connecting screw extending out of the base or the column is formed with a tapered end.

[0009] Furthermore, the length of the threaded sleeve is not shorter than the length of the connecting screw extending from the base end face or the cylinder end face.

[0010] Furthermore, the end face of the threaded sleeve is coplanar with the end face of the base or the end face of the cylinder.

[0011] Furthermore, the cross-sectional shape and size of the foundation and the column are the same.

[0012] Furthermore, the column and the base both have circular cross-sections.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] 1. The present application sets a connecting screw in the foundation or column, and sets a threaded sleeve in another component, so that when the column is installed on the foundation, it is only necessary to extend the connecting screw into the threaded sleeve and rotate the column to achieve the installation connection between the foundation and the column. The installation is quick and convenient, and the column can be more conveniently removed from the foundation later;

[0015] 2. The enlarged head can increase the anchoring force between the connecting screw and the column or foundation, making the connection strength between the connecting screw and the foundation or column stronger;

[0016] 3. A conical end is provided at the end of the connecting screw, so that the connecting screw is more easily aligned into the threaded sleeve, and the inclined surface of the conical end can guide the connecting screw when inserted into the threaded sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] Example 1

[0024] A connection node between a prefabricated column and a foundation, referring to Figure 1 and Figure 2, including a foundation 1 and a column 2 for installation on the top of the foundation 1, a threaded sleeve 3 is pre-buried in the foundation 1, and a connecting screw 4 is pre-buried in the column 2. When the column 2 is installed on the top of the foundation 1, the connecting screw 4 is inserted into the threaded sleeve 3, and the column 2 is rotated until the end face of the column 2 and the end face of the foundation 1 abut, and the installation of the column 2 is completed; when disassembling the column 2, the column 2 can be separated from the foundation 1 by rotating the column 2 in the opposite direction.

[0025] Among them, the connecting screw 4 is partially embedded in the column 2 and partially extends out of the end face of the column 2. The length of the threaded sleeve 3 is not shorter than the length of the connecting screw 4 extending out of the end face of the column 2, so that the column 2 can be rotated until the end face of the column 2 abuts against the end face of the foundation 1. There is no gap between the foundation 1 and the column 2, and the installation is tighter.

[0026] In addition, the end face of the threaded sleeve 3 is coplanar with the end face of the foundation 1, so that the threaded sleeve 3 neither protrudes from the surface of the foundation 1 nor is recessed in the foundation 1, and has good aesthetics. If the threaded sleeve 3 protrudes from the surface of the foundation 1, there will be a gap between the column 2 and the foundation 1 after the column 2 is installed on the foundation 1; if the threaded sleeve 3 is recessed in the surface of the foundation 1, after the connecting screw 4 is installed on the threaded sleeve 3, there will be a movable space around the part of the connecting screw 4 near the end face of the foundation 1, which makes this section of the connecting screw 4 easy to deform or accumulate water.

[0027] Furthermore, the end of the connecting screw 4 located inside the column 2 is provided with an enlarged head 41, and the end located outside the column 2 is provided with a tapered end 42. The enlarged head 41 can strengthen the anchoring strength between the connecting screw 4 and the column 2, so that the connecting screw 4 is not easy to be separated from the column 2; the tapered end 42 is provided, because the inclined surface of the side wall of the tapered end 42 can guide the connecting screw 4 to be inserted into the threaded sleeve 3, so that the connecting screw 4 can be inserted into the threaded sleeve 3 more quickly and conveniently, which is convenient for the installation of the column 2.

[0028] The cross-sectional shape and size of the foundation 1 and the column 2 are the same, so after the column 2 is installed on the foundation 1, the appearance is better; preferably, the cross-sectional shape of the foundation 1 and the column 2 is circular. Since the number of rotations of the connecting screw 4 when installed on the threaded sleeve 3 is uncertain, if the foundation 1 and the column 2 are both circular, no matter how many times the column 2 is rotated, the side walls of the foundation 1 and the column 2 are coplanar, and the resulting structural appearance is more beautiful.

[0029] Example 2

[0030] The difference between Example 2 and Example 1 is that, referring to Figure 2 The threaded sleeve 3 is pre-buried in the column 2, and the connecting screw 4 is pre-buried in the foundation 1. When installing the column 2, it is only necessary to align the threaded sleeve 3 on the column 2 with the connecting screw 4 on the lower foundation 1 and rotate the column 2 to achieve the installation of the column 2.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
