Abstract

The utility model relates to a steel-wood combined push-pull keel which is composed of an outer keel assembly and an inner keel assembly. The inner keel assembly is inserted into the outer keel assembly so as to form a push-pull telescopic structure. Keel racks with different sizes and multiple using functions are convenient to be combined at will by upright posts, wall bodies, top plates and side beam surfaces with different specifications and shapes according to building construction parts. A wood beam does not need to adopt an entire wood material, a short wood beam can be utilized and a leftover can be lengthened, so as not to waste a square wood profile, thereby fundamentally eliminating wood wastes and achieving obvious wood saving effect; the setting-up and disassembling are simple, convenient and quick, repeated use can be carried out, the turnover is quick, the construction tool utilizing rate is increased, the construction cost is effectively lowered, and the keel is economical as well as practical; a secondary keel sleeve is arranged on the inner keel assembly, and locates on the same plane with an outer steel frame of the outer keel assembly; the construction setting-up is easy for leveling, so as to be beneficial for improving the structural forming quality of the keel rack; in the construction, corner wastes are reduced so as not to pollute the environment; with high bearing intensity, the keel can be used as a substitute product of a traditional square wood.

Description

Steel wood combination push-and-pull keel

Technical field

The utility model belongs to building operations apparatus field, relates to a kind of steel wood combination push-and-pull keel.

Background technology

The keel frame is the building unit of using always, is applied in the construction of heavy construction, and be one of important primary structure member.Existing keel frame adopts the lumps of wood to build usually, because the lumps of wood should be sawed and should dig, causes and arbitrarily cuts saw, the short usefulness of long material in the use, and the problem of a large amount of wastes of timber is very outstanding, and lumps of wood leftover bits and pieces and dust environmental pollution are serious simultaneously.

Because lumps of wood easy deformation and connect to produce loosening, planeness is not good enough, influence keel frame structure Forming Quality and safety of construction, and the making of lumps of wood keel frame, builds and dismounting is wasted time and energy, and is not easy to have enough to meet the need, and has strengthened construction cost.

At the defective that adopts the lumps of wood to build the keel frame, at present, steel wood double-plate keel comes out gradually, but generally be to adopt the lumps of wood is inlaid in the grooved steel plate, this one-piece keel structure, function of use is single, can not adjust length arbitrarily, range of application is limited, and still needs to consume whole lumps of wood section bar, does not check the timber waste from the source.
