The purpose of the utility model is to provide a profile guardrail to solve the problems existing in the above-mentioned prior art and to improve the quality, aesthetics and safety.

In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The utility model provides a profile guardrail, as shown in Figures 1 to 5, comprising at least two columns 1, a plurality of cross bars 2 and a cover plate 14, the columns 1 and the cross bars 2 are all profiles, a first side of the column 1 is provided with a cross bar mounting groove 11 extending along the length direction, a second side of the column 1 adjacent to the first side is provided with a bolt mounting groove 12 extending along the length direction, a plurality of cross bars 2 are horizontally and spaced between two adjacent columns 1, and both ends of the cross bars 2 are respectively inserted into the cross bar mounting groove 11, the ends of the cross bars 2 are provided with mounting holes, and the side plates on the opposite sides of the cross bar mounting groove 11 are provided with threaded holes corresponding to the mounting holes, bolts are installed from the bolt mounting groove 12 and sequentially pass through the side plate on one side of the cross bar mounting groove 11, the cross bar 2 and the side plate on the other side of the cross bar mounting groove 11 to fix the cross bar 2 in the cross bar mounting groove 11, and the cover plate 14 is installed on the bolt mounting groove 12 and covers the bolts.

Different from welding in the prior art, the profile guardrail provided by the utility model uses bolts to connect the cross bar 2 and the column 1 to ensure the quality, quality and aesthetics of the railing installation. In order to further improve the aesthetics, a cover plate 14 is installed on the bolt installation groove 12 to cover the bolts, and the outer wall of the cover plate 14 is flush with the outer wall of the column 1.

In some embodiments, as shown in Figure 7, the cross bar 2 includes a cross bar body 21 and a connecting piece 13 at the end. The connecting piece 13 is a groove-shaped profile. The connecting piece 13 is fixedly connected to the end of the cross bar body 21 by bolts. The cross bar body 21 is a hollow tube body, which is provided with a connecting groove extending along the length direction. The inner wall of the connecting groove is provided with a thread, so that the groove-shaped profile can be installed on the end of the cross bar body 21 by bolts. Specifically, the bottom plate of the groove-shaped profile is close to the end of the cross bar body 21, and the two opposite side plates of the groove-shaped profile extend from the bottom plate in the direction away from the cross bar body 21. The two opposite side plates of the connecting piece 13 are provided with mounting holes. More preferably, the connecting pieces 13 at the ends of multiple adjacent cross bar bodies 21 are integrated groove-shaped profiles, and each cross bar body 21 is connected to the connecting piece 13 by two bolts.

In some embodiments, as shown in FIG. 6 , both sides of the cover plate 14 in the width direction are provided with bayonet holes extending in the length direction, and a latch tongue matching the bayonet hole is provided on the second side of the column 1, and the latch tongue can be engaged in the bayonet hole to realize the installation of the cover plate 14. The cover plate 14 has the same length as the column 1, and the cover plate 14 can be inserted from the top of the column 1 and slide down. The bayonet hole can limit the movement of the latch tongue outward, and can only make it slide up and down along the height direction (the length direction of the column 1). In another embodiment, after the installation is completed, in order to limit the sliding of the bayonet hole, a cap 3 is covered on the top of the column 1.

In some embodiments, a base is provided at the bottom of the column 1, and the base is connected to the bottom of the column 1 by bolts. The base is installed on the cement floor by bolts or is directly cast in the cement floor. In order to improve the aesthetics, a cover is installed at the bottom of the column 1 to cover the bolts at the bottom of the column 1.

In some embodiments, in order to improve the versatility of the column 1, a cross bar mounting groove 11 is also provided on the side of the column 1 opposite to the first side, and two parallel bolt mounting grooves 12 are provided on the second side of the column 1. The two bolt mounting grooves 12 are respectively matched with the two cross bar mounting grooves 11 for use.

The column 1 in the profile guardrail provided in this embodiment can be used as a middle column 1. For example, when there are more than three columns 1, the two sides of the middle columns 1 need to be installed with cross bars 2. Therefore, a cross bar installation groove 11 needs to be set on both sides, and the column 1 close to the side can only be provided with a cross bar installation groove 11 on the inner side. Of course, in this embodiment, all the columns 1 are set to have a cross bar installation groove 11 on both sides to improve versatility. In this embodiment, in order to improve the aesthetics of the profile guardrail, a side cover plate 15 is installed on the cross bar installation groove 11 on the outer side of the column 1 close to the side of the profile guardrail. The side cover plate 15 closes the cross bar installation groove 11 and the outer side surface of the side cover plate 15 is located on the same plane as the outer side surface of the column 1. Specifically, the two sides of the side cover plate 15 in the width direction are provided with a bayonet extending along the length direction, and the two opposite sides of the cross bar installation groove 11 are provided with a tongue matching the bayonet, and the tongue can be snapped into the bayonet to achieve the installation of the side cover plate 15.

The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
