Door-type scaffold

Abstract

The invention discloses a door-type scaffold comprising a door panel and a ledger. The door panel comprises a door panel frame consisting of a cross bar and an upright pole of the door panel, and a fastener consisting of a buckle strip and two fastening parts; the fastening parts are fixed with the door panel frame; and the ledger is fixed between the buckle strip and the door panel frame. The optimal technical proposal comprises: a putlog is fixed on the ledger by using a banding tape; a guard rail is fixed on the upright pole of the door panel by using the banding tape; the door panel comprises a first door panel and a second door panel which are adjacent to each other longitudinally and have different widths; and the ledger extending out of the fastener of the first door panel is fixedwith the cross bar of the second door panel. In the door-type scaffold, the distance between the door panels is not limited by the length of the ledger any longer, therefore, the cost of the door-typescaffold can be reduced, and the door-type scaffold set up can be adapted to the longitudinal size of the building without using a plurality of models of legers for matching, thus being capable of reducing the stock of components and parts of the door-type scaffold.

Description

technical field [0001] The invention relates to a construction tool, in particular to a portal scaffold. Background technique [0002] At present, in building construction, it is often necessary to set up appropriate scaffolding to facilitate construction operations at high places. Among them, portal scaffolding is widely used because of its convenient and efficient construction and dismantling. [0003] Portal scaffolding generally includes a door frame and a large cross bar; the door frame includes a door frame cross bar and two vertical bars, and the two ends of the door frame bar are respectively fixed with the two vertical bars to form a door frame; when installing the scaffold, In the longitudinal direction, connect and fix the multi-piece gantry with appropriate large crossbars; in the vertical direction, use an adapted structure to fix the multi-piece gantry to form a scaffold with appropriate strength and size. Carry out building construction work. Since the por...

Problems solved by technology

Although the connection mechanism in the prior art can realize the connection between the large crossbar and the door frame, there are certain problems: the connection mechanism between the large crossbar and the door frame increases the manufacturing cost of the scaffold; at the same time, the connection mechanism It also makes the scaffolding construction and dismantling process more cumbersome, reducing the work efficiency of scaffolding construction and dismantling; in addition, the connecting mechanism also makes a non-rigid hinge point between the large crossbar and the portal frame, thereby weakening the rigidity of the portal scaffolding. strength and stability

[0006] Due to the lack of strength and stability of the existing portal scaffolding, it is necessary to lay scaffolding boards on each working surface of the portal scaffolding to increase the The strength and stability of scaffolding; however, in the process of exterior wall construction, a two-step working layer can meet the requirements of the working surface, and laying scaffolding boards on each working surface obviously causes waste of scaffolding boards; at the same time, each step The laying of the scaffolding will also allow the construction workers to pile up building materials on the scaffolding at will, which will easily cause the scaffolding to be overloaded and affect the construction safety.

[0007] In addition, during the construction process, when there are balconies, air-conditioning panels or railings, there will be convex structures on the surface of the building; using existing technology to provide scaffolding, When the length of the large crossbar does not match the convex structure, it is necessary to use large crossbars of various types or lengths to match the scaffolding with the convex structure on the surface of the building; thus, it is necessary to prepare a variety of The long crossbar increases the inventory of equipment, which makes the management of construction materials more difficult and increases the construction cost

Moreover, it is also difficult to ensure a suitable distance between the scaffold and the working surface with large crossbars of various types or lengths; when the distance between the portal scaffold and the working surface is not suitable, the construction work will be very difficult
