Description

Technical Field

[0001] This utility model relates to the field of space frame connection technology, and more specifically to a connection device for installing steel structure space frame members. Background Technology

[0002] Steel space frame is a type of building structure. It consists of many members connected by nodes according to a certain geometric shape to form a spatial grid structure. It has the following advantages: high strength and lightweight, good spatial performance, fast construction speed, beautiful appearance, and good seismic performance.

[0003] During the assembly of steel space frames, specialized connecting devices are required to connect the various members. In existing technologies, bolted balls and welded balls are often used to connect the members. However, the connection positions between the surface of the bolted ball and the member are fixed. In space frames, many members are already connected to adjacent connecting devices before being connected to the bolted ball or welded ball. Furthermore, due to temperature and assembly errors, the members may have shifted to some extent. At this point, it is difficult or even impossible for the member to align with the connection points on the surface of the welded ball or bolted ball, resulting in installation difficulties or even installation failures. This necessitates the use of other compensating parts for positional compensation. Overall, the use of these devices still has certain limitations. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a connecting device for installing steel structure space frame members, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a connecting device for installing steel structure space frame members, including a connecting seat, a connecting sleeve and a connecting assembly. The connecting assembly is installed between the connecting sleeve and the connecting seat, and the connecting sleeve can rotate on the surface of the connecting seat through the connecting assembly. There are several connecting sleeves, which are distributed on the surface of the connecting seat. The connecting seat is a combined structure, including two sub-seats, which are detachably fixed together. The connecting sleeves are respectively distributed on the surfaces of the two sub-seats.

[0006] Furthermore, the connecting assembly includes a connecting hemisphere and a spherical groove. The spherical groove is formed on the surface of the connecting seat. The connecting hemisphere is rotatably mounted in the spherical groove and can only rotate within the spherical groove. The end of the connecting sleeve passes through the spherical groove and is fixedly connected to the connecting hemisphere.

[0007] Furthermore, the connecting assembly also includes a bearing groove and a bearing column. The bearing groove is located in the middle of the inner bottom of the spherical groove. The bearing column is rotatably installed in the bearing groove and is fixedly connected to the connecting hemisphere. When the connecting hemisphere rotates, the bearing column rotates synchronously in the bearing groove.

[0008] Furthermore, the sub-seat includes two identical half-seats, with spherical grooves opened on opposite sides of the two half-seats, and each half-seat occupies half of the spherical groove and half of the bearing groove.

[0009] Furthermore, positioning holes are provided on the sides of both seats, and fixing bolts are inserted into the positioning holes. The two half seats are fixed together by fixing bolts.

[0010] Furthermore, each of the two sub-seats has a through hole in the middle, and a double-ended bolt is inserted into the through hole. A locking nut is installed on the threaded surface of the double-ended bolt, and the two sub-seats are clamped in the middle of the double-ended bolt by the locking nut.

[0011] Furthermore, the ends of the double-ended bolts and the ends of the connecting sleeves away from the connecting seat are all machined with threaded holes, and are connected to the ends of the space frame members through the threaded holes.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. In the entire process of use, this utility model connects to the rods in the space frame through a rotatable connecting sleeve. It can be aligned with the offset space frame rods by its own rotation, so that no other compensation parts are needed for installation, which greatly facilitates the installation of the space frame.

[0014] 2. In the process of use, the relative positions of the two sub-seats of this utility model can be adjusted to correspond with the space frame members at different offset positions, which further facilitates the installation of the space frame. In addition, since the entire connecting device is composed of multiple parts, when a certain part is damaged, that part can be directly replaced, thus eliminating the need for overall replacement and effectively reducing the cost of use.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figure 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1-4 The present invention will be further described below.

[0022] A connecting device for installing steel structure space frame members includes a connecting seat 1, a connecting sleeve 2, and a connecting assembly. The connecting assembly is installed between the connecting sleeve 2 and the connecting seat 1, and the connecting sleeve 2 can rotate on the surface of the connecting seat 1 through the connecting assembly. There are several connecting sleeves 2, which are distributed on the surface of the connecting seat 1. The connecting seat 1 is a combined structure, including two sub-seats 3, which are detachably fixed together. The connecting sleeves 2 are respectively distributed on the surfaces of the two sub-seats 3.

[0023] When in use, if the members in the space frame are offset, the connecting sleeve 2 at the corresponding position can be rotated to align it with the space frame member, thus facilitating installation. If the offset is large, the two sub-seats 3 can be disassembled for connection.

[0024] The connecting assembly includes a connecting hemisphere 4 and a spherical groove 5. The spherical groove 5 is formed on the surface of the connecting seat 1. The connecting hemisphere 4 is rotatably installed in the spherical groove 5, and the connecting hemisphere 4 can only rotate within the spherical groove 5. The end of the connecting sleeve 2 passes through the spherical groove 5 and is fixedly connected to the connecting hemisphere 4. In this way, after the end of the rod in the space frame is connected to the connecting sleeve 2, the stability of the space frame rod after connection can be ensured because the connecting hemisphere 4 can only rotate within the spherical groove 5.

[0025] The connecting assembly also includes a bearing groove 6 and a bearing column 7. The bearing groove 6 is located in the middle of the inner bottom of the spherical groove 5. The bearing column 7 is rotatably installed in the bearing groove 6 and is fixedly connected to the connecting hemisphere 4. When the connecting hemisphere 4 rotates, the bearing column 7 rotates synchronously in the bearing groove 6. Thus, when a certain member applies pressure to the connecting hemisphere 4, the pressure will be transmitted to the entire connecting seat 1 through the bearing column 7.

[0026] The split seat 3 includes two identical half seats 8. Spherical grooves 5 are opened on the opposite side of the two half seats 8, and each half seat 8 occupies half of the spherical groove 5 and half of the bearing groove 6, so that it is convenient to assemble and replace parts.

[0027] Both of the two sub-seats 3 have positioning holes 9 on their sides, and fixing bolts 10 are inserted into the positioning holes 9. The two half-seats 8 are fixed together by the fixing bolts 10, thus forming a connecting seat 1.

[0028] Both sub-seats 3 have through holes in the middle, and double-ended bolts 11 are inserted into the through holes. Locking nuts 12 are installed on the threads of the double-ended bolts 11, and the two sub-seats 3 are clamped in the middle of the double-ended bolts 11 by the locking nuts 12. In this way, the sub-seats 3 can be rotated by loosening the locking nuts 12 to achieve multi-angle and multi-displacement compensation.

[0029] The ends of the double-ended bolt 11 and the ends of the connecting sleeve 2 away from the connecting seat 1 are both machined with threaded holes, and are connected to the ends of the space frame members through the threaded holes.

[0030] Therefore, the complete usage process is as follows: First, install the connecting hemisphere 4 and the bearing column 7 into the spherical groove 5 and bearing groove 6 on one half seat 8, respectively. Then, engage the other half seat 8 with it. Next, use the fixing bolt 10 to tighten the two half seats 8 to form a split seat 3. Repeat the above steps to assemble the other split seat 3. At this time, put the two split seats 3 in the middle of the double-ended bolt 11 and use the locking nut 12 to clamp the two split seats 3 in the middle of the double-ended bolt 11, thereby completing the assembly of the entire connecting device.

[0031] Subsequently, during the installation of the space frame, when the members in the space frame shift, the connecting sleeve 2 at the corresponding position can be rotated to align it with the space frame member, thus facilitating installation.

[0032] Meanwhile, if the offset is large, the locking nut 12 can be loosened, allowing the sub-seat 3 to slide a distance on the double-ended bolt 11 to align with the space frame member. After the connecting sleeve 2 is connected to the space frame member, the two sub-seats 3 are then tightened again in the middle of the double-ended bolt 11 to further facilitate installation.

[0033] In summary, during the entire process of use, the rotatable connecting sleeve 2 is connected to the members in the space frame. It can be aligned with the space frame members that have shifted due to its own rotation, so that no other compensation parts are needed for installation, which greatly facilitates the installation of the space frame.

[0034] Meanwhile, during use, the relative positions of the two sub-seats 3 can be adjusted to correspond with the space frame members at different offset positions, which further facilitates the installation of the space frame. In addition, since the entire connecting device is composed of multiple parts, when a certain part is damaged, that part can be directly replaced, thus eliminating the need for overall replacement and effectively reducing the cost of use.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
