Easily install and wide scaffold frame of encorbelmenting of application scope

Technical Field

The utility model relates to the technical field of scaffolds installed in building openings by cantilevers or other devices, in particular to an overhanging scaffold which is easy to install and wide in application range.

Background

The scaffold for the outer wall of the building mainly comprises two main types: the scaffold is hung on the ground. The floor scaffold is reliable in structure, can be installed layer by layer up by self without an additional high-altitude operation platform, is high in cost, and is suitable for being used when all floors from bottom to top need outer wall operation. The overhanging scaffold has lower cost (because the overhanging scaffold can be arranged according to the requirement, for example, only one layer and two layers are arranged), but the overhanging scaffold is relatively difficult to install, and the overhanging scaffold cannot be used as an installation platform by itself during installation.

The structure of the existing overhanging scaffold mainly comprises overhanging beams extending out of a building and a steel pipe rack arranged on the overhanging beams, and stay ropes are further arranged when the overhanging distance is longer.

Most cantilever beams of the cantilever scaffold are fixed by means of embedded parts on the floor, the fixing mode is simple and reliable, the embedded parts are required to be installed on the floor in advance, and meanwhile, if a short wall or a guardrail for blocking the cantilever beams from extending is arranged at the edge of a building, the cantilever beams cannot be used. When the cantilever beam cannot be fixed by using the embedded part on the floor slab, a constructor can choose to directly fix the end part of the cantilever beam on the outer wall of the building, the fixing process is difficult, the construction cannot be carried out from the floor slab, other high-altitude operation platforms such as a scaffold/arm lifting vehicle/construction hanging basket below are also needed, and meanwhile, more hands are needed because the cantilever beam in installation is lack of fixation.

Detailed Description

As shown in fig. 1-2, the cantilever scaffold easy to install and wide in application range comprises a cantilever beam 1 extending outwards from a building, a springboard paved on the cantilever beam 1, a stay cable 2 with the lower end fixed on the cantilever end of the cantilever beam 1 and the upper end fixed on the cantilever beam 1, and a steel tube frame 3 detachably fixed on the cantilever beam 1, wherein the root of the cantilever beam 1 is anchored on a side elevation of the building, the upper surface of the cantilever beam is flush with a floor slab of a floor where the cantilever beam 1 is positioned, a mounting rope 5 for enabling constructors to maintain the posture of the cantilever beam 1 when pushing the cantilever beam 1 outwards from the building, and a guide rod 4 for enabling constructors to maintain the pointing direction of the cantilever beam 1 when pushing the cantilever beam 1 outwards from the building are further arranged above the cantilever beam 1, the upper end of the mounting rope 5 is connected with the upper end of the stay cable 2 into a whole, the lower end of the guide rod 4 is detachably fixed on the upper part of the cantilever beam 1, one end of the guide rod 4 is detachably anchored in the middle of the cantilever beam 1, and the other end of the guide rod extends into the building.

The cantilever beam 1 which is most difficult to install in the cantilever scaffold is easy to install, and the application range is wide, and the cantilever beam is applicable to the condition that no embedded part exists or the edge of a floor slab is provided with a short wall or a guardrail for preventing the cantilever beam 1 from extending. Because many construction occasions that need use the scaffold frame of encorbelmenting belong to the outer wall construction operation (like the building outer wall fitment of owner's self organization) outside the construction planning, often do not have the built-in fitting on the floor in this time, if install cantilever beam 1 in the floor punching, can cause the destruction to the floor again.

The lower end of the installation rope 5 is hung on a lifting lug at the root of the cantilever beam 1 through a hook and is taken down after the cantilever beam 1 is installed, so that the stress of the whole cantilever scaffold after installation is prevented from being influenced. In this embodiment, the installation rope 5 is a chain block, that is to say, it is also a component that can assist in lifting, can practice thrift the manpower in the installation cantilever beam 1, and length adjustable simultaneously, consequently can adjust, the height of cantilever beam 1 root, the misalignment of cantilever beam 1 root and bolt when avoiding adopting the installation rope 5 of non-adjustable length.

The cantilever beam 1 is welded with a inserted link for inserting into the steel pipe frame 3 to fix the steel pipe frame 3, the guide link 4 is a steel pipe with a curved shape, and the guide link 4 is sleeved on the inserted link and locked by a pin in the installation process of the cantilever beam 1. The primary purpose of the guide bar 4 here is to align the bolt holes in the root of the cantilever beam 1 with the bolts on the outer wall of the building, while the curved shape is to bypass elements that may cause obstruction, such as short walls or guardrails, around the floor edges.

The stay cable 2 is a steel cable with a basket bolt, and the upper end of the stay cable 2 is anchored at the floor edge above the cantilever beam 1. The steel cable with the basket bolts is adopted to tighten the stay cable 2 after the cantilever beam 1 is installed.

The cantilever beam 1 is an I-shaped steel beam, a connecting plate perpendicular to the cantilever beam 1 is welded at the root of the cantilever beam 1, and the cantilever beam 1 is detachably and fixedly connected with a building through a chemical anchor bolt or an embedded anchor bolt penetrating through the connecting plate from the building.

The embedded anchor bolts are used when the overhanging scaffold is involved in construction planning, if the construction is temporarily and intentionally performed, the chemical anchor bolts are needed, the installation workload of the chemical anchor bolts is small and the chemical anchor bolts do not need to be used, the embedded anchor bolts can be directly laid on the edge of the floor to be punched and installed, and even if a guardrail exists, the embedded anchor bolts can be manually stretched from the seams of the guardrail to perform construction. When the chemical anchor bolts cannot be installed on the floor, constructors can directly hang the floor edges for short distance to construct, and the installation of the air conditioner external unit can be referred. The upper end of the stay cable 2 is installed in the same way.

The cantilever scaffold is easy to install and wide in application range, and the construction method comprises the following steps:

step one: installing the stay cable 2 and the upper end of the installation rope 5 on the upper floor edge;

step two: the lower ends of the stay ropes 2, the installation ropes 5 and the guide rods 4 are installed on the cantilever beams 1, and the cantilever beams 1 are pushed out of the building;

step three: the position of the cantilever beam 1 is adjusted by a guide rod 4, so that the root of the cantilever beam 1 is aligned with a chemical anchor bolt or an embedded anchor bolt, and then nuts are screwed for fixing;

step four: paving a springboard, and then installing a steel pipe rack 3; after the steel pipe frame 3 is assembled in the building, the installation rope 5 and the guide rod 4 are taken down, and the steel pipe frame is hoisted by means of the installation rope 5 as a hoisting tool.

The above examples are only illustrative of the preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, and various modifications and improvements made by those skilled in the art to the technical solution of the present utility model should fall within the scope of protection defined by the claims of the present utility model without departing from the spirit of the present utility model.
