Description

Technical Field

[0005]

[0001] This application relates to the technical field of building mechanical and electrical installation, and particularly relates to a truss-type connector. Background Art

[0002] When installing mechanical and electrical structures such as photovoltaic panels on the roof, installation frames are often erected. The general installation frame structure is to install columns first, and then install the truss between the columns through connectors. The truss includes structures such as C-shaped steel and square steel.

[0003] The commonly used connector structure is "L"-shaped and is installed on the column and the truss through bolts, thereby realizing the installation and fixation of the column and the truss. When connecting with this structure, there will be a problem of low installation strength. And when fixing multiple trusses on one column, multiple connectors will be used accordingly. However, after installation, the overall stress structure is unstable, the integrity is poor, and the load transfer is uneven. Utility Model Content

[0004] The purpose proposed by the utility model of this application is to improve the disadvantages of the poor connection and fixation effect of the truss connector, and the poor integrity and uneven load transfer when using multiple connectors. This application provides a truss-type connector.

[0005] A truss-type connector provided by this application adopts the following technical solutions:

[0006] A truss-type connector includes

[0007] An installation frame, with a "凵"-shaped cross-section, capable of wrapping the bottom of the truss;

[0008] A vertical plate, fixedly arranged at one end of the lower surface of the installation frame, for fitting with the column;

[0009] A plurality of installation holes for bolts to pass through are provided on the lower surface of the installation frame and the vertical plate.

[0010] Optionally, when installing multiple adjacent connectors on one column, the vertical plates of the connectors are fixed into a whole.

[0011] Optionally, when two connectors are installed on one column and are opposite to each other, a connecting plate is fixedly arranged on the side wall of the vertical plate. The connecting plate fits with the column and connects the two vertical plates to form a cylindrical structure. [[ID=​​​​​​​​​

[0015] Optionally, the side walls of the mounting frames of adjacent connecting members are also fixedly connected to each other.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. Compared with the "L"-shaped connector, the mounting frame can better and more stably support and fix the bottom of the truss, and fasten the vertical plate to the column to achieve the connection and fixation of the column and truss, thereby improving the stability of the connection and fixation between the column and truss;

[0018] 2. When multiple connectors are used together, adjacent connectors are fixedly connected to each other to form a whole, thereby improving the firmness of the trusses with multiple branches on the top of the column and improving the uniformity of load transfer;

[0019] 3. When two connecting parts are arranged opposite to each other, the connecting plate is used to fix the two connecting parts to each other, thereby improving the integrity of the two connecting parts and improving the uniformity of load transfer;

[0020] 4. The setting of the mounting holes on the side wall of the mounting frame can improve the firmness of the fixation between the truss and the mounting frame. The inclined setting of the top of the side wall of the mounting frame can facilitate the insertion of gaskets between the mounting frame and the truss to improve the stability of the fixation between the mounting frame and the truss and reduce vibration transmission.

[0027] The following is combined with Figure 1-5 This application is described in further detail.

[0028] The embodiment of the present application discloses a truss-type connector.

[0029] refer to Figure 1 , the truss - type connector includes an installation frame 1 and a vertical plate 2. The installation frame 1 has a "U" - shaped cross - section and can wrap the bottom of the truss. The vertical plate 2 is fixedly arranged at one end of the lower surface of the installation frame 1 and is used to fit with the column, and is perpendicularly arranged with respect to the lower surface of the installation frame 1. A plurality of installation holes 11 for bolts to pass through are provided on the lower surface of the installation frame 1, the side wall of the installation frame 1, and the vertical plate 2. A rib plate 12 fixedly connected to the vertical plate 2 is provided on the lower surface of the installation frame 1. The top of the inner side wall of the installation frame 1 is inclined and transitioned. In this embodiment, the truss is a C - shaped steel, and the connector can also be applicable to the installation of square - steel trusses.

[0030] The bottom of the truss is wrapped and fixed by the installation frame 1, and then the side wall of the column is fitted and fixed by the vertical plate 2, thereby realizing the fixation of one end of the truss to the column. The wrapping structure of the installation frame 1 can effectively improve the firmness and stability of the fixation of the truss. The side wall of the installation frame 1 can also be bolt - fastened to the side wall of the truss through the installation holes 11. When there is a spacing between the truss and the inner wall of the installation frame 1, the vibration conduction can also be reduced by inserting a gasket between the installation frame 1 and the truss. At the same time, the inclined surface setting also facilitates the insertion of the installation frame 1 on the truss.

[0031] Reference Figure 2 , the connector takes the combination of one installation frame 1 and one vertical plate 2 as a unit. The vertical plates 2 of two units are welded to each other, and the side walls of the installation frames 1 of the two units are welded to each other to form a new connector, which is used when the truss on the column is in an "L" shape.

[0032] Reference Figure 3 , in the three - connector - unit case, the adjacent two vertical plates 2 of the three connector units are welded to each other, and the adjacent side walls of the installation frames 1 of the three units are welded to each other to form a new connector, which is used when the truss on the column has three branches.

[0033] Reference Figure 4 , in the four - connector - unit case, the adjacent two vertical plates 2 of the four connector units are welded to each other, and the adjacent side walls of the installation frames 1 are welded and fixedly arranged to form a new connector, which is used when the truss on the column is in a "cross" - shaped four - branch shape. When in use, the sleeve structure composed of the four vertical plates 2 is sleeved on the column for fixed use.

[0034] Reference Figure 5 , the vertical plates 2 of two connector units are arranged oppositely, and a connecting plate 3 is fixedly arranged on the side wall of the vertical plate 2. The two connecting plates 3 and the two vertical plates 2 form a sleeve structure, which is used for the case where the truss on the column has two symmetric branches. When in use, the sleeve structure composed of the connecting plate 3 and the vertical plate 2 is sleeved on the column for fixed use.

[0035] By using this combination method of prefabricated parts to fix the trusses in different situations on the upright posts, multiple connectors form an integral structure, thereby effectively improving the stability of the truss installation and fixation and enhancing the uniformity of load transfer.

[0036] The implementation principle of a truss-type connector in an embodiment of this application is as follows: The "U"-shaped wrapping structure of the installation frame 1 wraps the bottom of the truss, and in cooperation with the vertical plate 2, effectively improves the fixing stability of the truss and the upright post. At the same time, since the structure of the vertical plate 2 that fits the upright post is a plate that only fits one side wall of the upright post, the connectors can be combined and fixed according to the installation requirements, so that multiple connectors fixed on the upright post form an integral body, further improving the firmness and stability of the truss installation and fixation, and effectively enhancing the uniformity of load transfer.

[0037] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
