Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a highly adaptable triangular steel column support for door and window openings. Background Technology

[0002] Tripod scaffolding is an important component of building construction. Commonly used tripod scaffolding types in construction include ground-supported scaffolding, frame scaffolding, and cantilever scaffolding. Cantilever scaffolding, a relatively new scaffolding system developed in recent years, has gained widespread application due to its flexibility and adaptability. Triangular steel cantilever scaffolding is an important form of cantilever scaffolding. It typically consists of fixed steel columns, triangular supports, and an upper frame. The fixed steel columns are primarily used at door and window openings, serving as support points for the triangular supports. The columns themselves are made of I-beams, while the upper sections that contact the wall or beam use channel steel or welded steel plates. In traditional tripod steel columns, the upper sections contacting the wall or beam were welded to a fixed length. This meant that each type of steel column could only be fitted with one thickness for strength. In construction projects, there are often walls of various thicknesses. This means that each wall thickness requires a different type of steel column, which greatly increases the construction cost and reduces the flexibility and adaptability of the steel columns, as well as increasing the difficulty of construction. Utility Model Content

[0003] The purpose of this utility model is to provide a highly adaptable triangular steel column support for door and window openings, which solves the problems of poor flexibility and poor adaptability of conventional fixed steel columns.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A highly adaptable triangular steel column support for door and window openings includes a column support structure and a triangular frame fixed to the column support structure and cantilevered outside the door and window opening. The triangular frame is used to support an outdoor operating platform. The column support structure includes a column body and a bottom support and a top support located at the bottom and top of the column body, respectively. The bottom support is anchored to the wall or floor below and includes an L-shaped connecting support and a steel section support located on the indoor side. One end of the L-shaped connecting support is detachably connected to the vertical part by bolts, and the other end is anchored to the wall or beam.

[0006] More preferably, the bottom support groove is set upward, and the column body is fixedly connected by spot welding after being attached back to back of two I-beams, and the bottom part of the column body extends into the groove of the bottom support and is welded and fixed.

[0007] Furthermore, the L-shaped connecting brace is formed by welding horizontal and vertical channel steels, with the horizontal channel steel opening facing downwards and the vertical channel steel opening facing away from the wall or beam.

[0008] Furthermore, the width of the steel brace is adapted to the distance between the vertical part of the L-shaped connecting brace and the wall or beam.

[0009] Furthermore, the tripod and the column body are detachably fixed by through bolts.

[0010] Furthermore, the tripod includes a horizontal brace, a vertical brace, and a diagonal brace connecting the horizontal brace and the vertical brace. The horizontal brace, the vertical brace, and the diagonal brace form a right-angled triangular support frame, and the right-angled triangular support frame is provided with a Z-shaped reinforcing brace inside.

[0011] Furthermore, the tripod is formed by welding angle steel.

[0012] In addition, a reinforcing steel frame is welded to the vertical support at the part where the through-bolt passes through, and the washer of the through-bolt is filled between the reinforcing steel frame and the vertical support.

[0013] More preferably, the top surface of the column body is set at a certain distance from the bottom surface of the wall or beam above.

[0014] Compared with the prior art, this utility model has the following features and beneficial effects:

[0015] The steel column fixing support of this application can be anchored to the wall or floor slab at the bottom with bolts, and fixed to the wall or beam at the top with steel braces (channel steel) of different lengths and models. The whole can be fixed by selecting channel steel of different lengths and models according to the thickness difference of the wall or beam to which it overlaps, adapting to the thickness of various wall or beam models. It is simple to manufacture, easy to install, flexible to use and widely adaptable, and has important promotional value. Attached Figure Description
