Abstract

The invention discloses a supporting beam, which mainly consists of a quadrilateral tubular beam and a U-shaped part inserted into side surfaces of the tubular beam. Small holes are arranged at the bottom of the U-shaped part, and mounting screws are connected with another component of furniture via the small holes. The invention further provides a method for processing and manufacturing the supporting beam. The method includes following steps: (1) arranging the small holes at the bottom of the U-shaped part; (2) inserting the U-shaped part into the tubular beam; and (3) vertically punching and riveting the tubular beam to form an inner fastener, fixedly riveting the U-shaped part onto the inner walls of the tubular wall and arranging an upper opening groove and a lower opening groove on the tubular beam. The supporting beam is simple in appearance, fine in rigidity and simple in processing and manufacturing.

Description

A kind of brace summer

Technical field

The present invention relates to a kind of furniture and interior decoration field, relate in particular to a kind of in furniture and interior decoration member the brace summer of passive metal framework.

Background technology

The table top of the wooden tables' furniture of tradition is mainly made up of arm-tie or pull bar between thick and heavy wooden batter and batter, and this class formation can be designed to class " work " word structure conventionally; The complete wooden tables' class furniture of part adopts larger circular or special-shaped cylindricality pin body as supporting component, these passive columnar member dead weights are larger, the area that lands is also larger, land with it deck plate that area matches, for example a circular dining table of independent support well.The supporting construction of these wooden tables' class furniture all forms the comparatively structure of sealing below table top, thereby forms a lot of corner or spot as yet untouched by a clean-up campaign, is also unfavorable for circulation of air.The tables' class furniture that only has part to make with natural hardwood, just adopt three less above independent foots to form supporting construction, although natural hardwood is according to there being good comprehensive strength, the cost of its Gao Mao, can moulding process single and gradually rare resource hindering it and entering mass consumption layer.Along with the utilization that deepens continuously of hardware, there is deep variation in tables' class furniture table-board supporting component.Hardware is built consensus with its good case hardness, comprehensive strength, moulding process variation, durability, repeated disassembled and assembled usability etc.Tables' metallic support framework of, stabilized structure with low cost for obtaining, dismantled and assembled (dismantled and assembled itself is also the performance of instant packed transport), handles well and being connected between batter and crossbeam becomes key technology.Simultaneously due to for obtaining the good metallic support assembly of rigidity, metal assembly adopts hollow-core construction (as pipe) more, but hollow structure to bring other problem be to conduct oneself with dignity gentlyer, make it soil fertility less (deck plate weight is much larger than supporting component gross weight).Therefore only have enough good support frames of the rigidity of acquisition, guarantee tables do not produce and rock in the time being subject to external force.

The beam of tables' class furniture that known metal framework supports has several as follows: the first is utilized opening shape " U " the section beam of plate-shape metal bending or metal pultrusion, and then utilizes welded flange etc. to be connected with batter; The second utilizes tubular metal thing to make beam, is subdivided into again several as follows with the connected mode of batter: (1) utilization is welded on pipe end flange and is connected with batter; (2) welding or connection third party part on batter, insert this third party's part in pipe beam, then connect with screw etc. at pipe STH; (3) third party's part is inserted to pipe beam inside, be connected with this third party's part at pipe beam STH after (beam of pultrusion can utilize pultrusion produce hole or groove tapping after third party's part in axial connection, also may be that self-tapping screw connects), then third party's part is connected with batter.In above-mentioned several beam, employing welding procedure, occupational hazards and environmental pollution can be produced; The flange that weldering (companys) is connected on beam-ends can add the profile Package size of crossbeam, welds () and be connected on third party's part on batter and also can strengthen the profile Package size of batter; Adding of third party's part, has increased the risk of Joint failure, and production technology is comparatively complicated simultaneously; From the connected mode of beam sides, in the time that tables are stressed, connector (screw) bears shearing force, very easily produces and becomes flexible, thereby produce loosening and Joint failure; More obviously feature shows as high expensive.

Summary of the invention

Object of the present invention be just to provide a kind of simple in structure, with low cost, manufacture easy for installation, sound construction, brace summer that packaging space is little.

In order to implement above-mentioned purpose, brace summer of the present invention is mainly made up of a quadrangle tubular beams, a U-shaped part that inserts tubulose beam sides, U-shaped part bottom surface (being the end face of beam) is provided with aperture, be connected for other members of mounting screw and furniture, the tubular beams of U-shaped part upper and lower is inwardly detained to U-shaped part, correspondingly, at brace summer upper and lower, the open slot that is fixedly connected with the batter of brace summer and furniture for screw is set.

Preferably, the present invention, except above-mentioned member, also can be provided with screw, rivet.

Preferably, U-shaped part bottom surface is provided with two or aperture, makes fastening better effects if.

Preferably, the bottom surface of U-shaped part is slightly recessed with respect to quadrangle tubular beams end face.

The tubular beams of U-shaped part upper and lower of the present invention is inwardly detained to U-shaped part, from technique, system realizes interior button by the tubular beams sheet metal that rushes riveting U-shaped part upper and lower, be connected with the batter of furniture at the U-shaped part of tubular beams inside by rushing riveting, U-shaped part is used as the reinforcement of brace summer in connecting batter.The open slot that tubular beams is rushed riveting generation can be used as spanner space simultaneously, is fixedly connected with the batter of tubular beams and furniture for screw.

Preferably, the corresponding position of U-shaped part of the present invention and tubular beams side is provided with perforate, for being spirally connected or riveting other members that fastening U-shaped part is connected with tubular beams and/or with two members.

U-shaped part of the present invention can laterally also can longitudinally insert tubulose beam sides.

The present invention also provides the machining manufacture of above-mentioned brace summer, and it comprises the steps:

(1) offer aperture in the bottom surface of a U-shaped part;

(2), at tubular beams upper and lower, longitudinally open a hole isometric with U-shaped part along center line;

(3) U-shaped part is inserted in a tubular beams;

(4) form interior button by upper undershoot riveting tubular beams and the riveting of U-shaped part is fixed on to the inwall of tubular beams, and produce upper and lower two open slots in tubular beams.

The present invention produces following beneficial effect: girder steel profile is simple, good rigidly, and processing and manufacturing is simple, installing space is little.

Below in conjunction with drawings and Examples, the invention will be further described.But the present invention is not limited to these embodiment, any improvement on essence spirit of the present invention or substitute, still belongs to the present invention's scope required for protection.
