Description

Technical Field

[0001] This utility model relates to the technical field of external scaffolding in building construction, and in particular to a novel external scaffolding device. Background Technology

[0002] External scaffolding is usually made of rigid materials such as steel pipes, couplers, and embedded parts, playing an important role in resisting wind loads and maintaining stability.

[0003] Traditional external scaffolding requires steel pipes to be embedded in the stable surface for rigid connection, which are then connected to the scaffolding after demolding. Especially for external scaffolding in the foundation pit and trench locations, it is necessary to pre-embed steel pipes in the capping beam or the top of the foundation pit. However, when the project starts, the project has often just entered the site and the external scaffolding structure has not been arranged, so it is impossible to confirm the location of the pre-embedded steel pipes. This makes it difficult to set up external scaffolding in the foundation pit and trench locations, which in turn affects the progress of the entire project. Utility Model Content

[0004] In order to improve the problem of difficulty in setting up external scaffolding in the above-mentioned background art, this utility model provides a new type of external scaffolding device.

[0005] The novel external scaffolding device provided by this utility model adopts the following technical solution:

[0006] A novel external scaffolding device includes main uprights and horizontal bars. Multiple main uprights are distributed in a matrix on one side of the wall. Connectors are equidistantly arranged vertically along the upper edge of each main upright. The ends of the horizontal bars are connected to the connectors via fasteners. Each connector has a disc-shaped structure with teeth around its edge. Mounting holes are formed around the connector's axis. The fasteners are clamped and locked in the mounting holes. A base plate is connected to the bottom of each main upright, and the base plate is fixed to a stable surface by expansion bolts.

[0007] Preferably, the upper half of the connecting fastener has a pin that passes through it, and the pin passes through the upper half of the connecting fastener and the mounting hole in sequence, and is fixedly inserted into the lower half of the connecting fastener.

[0008] Preferably, the inner side of the connecting fastener is provided with a toothed groove that matches the tooth pattern.

[0009] Preferably, diagonal braces are provided between the main frame uprights, and the two ends of the diagonal braces are diagonally connected between adjacent or opposite main frame uprights.

[0010] Preferably, a sweeping rod is connected between the bottom sections of the main frame uprights.

[0011] Preferably, a safety net is installed between the main frame uprights.

[0012] Preferably, the base plate has four positioning bolt holes around the axis, and expansion bolts pass through the positioning bolt holes. The expansion bolts are fixed by nuts, and two washers are provided between the portion of the expansion bolts located above the base plate and the base plate.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] 1. This utility model can be laid out according to the installation requirements of external scaffolding without the need for advance detailed layout and pre-embedding work of external scaffolding. The scaffolding is fixed to a stable surface by a base plate, making installation and use convenient and quick. The installation structure of external scaffolding is relatively simple, and each component can be recycled and reused, resulting in good economic and environmental benefits.

[0015] 2. This utility model uses connectors and fasteners to fasten external scaffolding. A pin is inserted into the mounting hole. The teeth on the edge of the connector engage with the teeth groove on the inner side of the fastener to fix it, ensuring that the connection position of the external scaffolding will not slip or loosen.
