Abstract

The utility relates to a support device for suspending and fixing apparatus at architecture or public facility, more specificly a weld-free bracket arm which comprise a vertical column and suspending arm. The vertical column possesses longitudinally run-through internal cavity whose back and two sides are all wall panel and front possesses longitudinally run-through sliding groove, whose breadth is less than that of internal cavity. Blocking brim is formed at edge of sliding groove. The suspending arm has a upper panel, a lower panel and side panel for connecting upper and lower panel. Back of upper panel is mounted with a vertical connection plate leaning against vertical column outside of sliding groove, and inside the sliding groove is mounted with a sliding nut whose breadth is larger than sliding groove. A bolt penetrates connection plate and sliding groove and is engaged with sliding nut. Part of the lower panel back converges, and the resulting the necking part is placed in sliding groove. The present utility doesn't need welding and fixing , and can adjust height of suspending arm according to need.

Description

Exempt to weld trailing arm

Technical field

The utility model relates to a kind of employed bracing or strutting arrangement when hanging fixedly various device in fields of employment such as buildings, communal facilitys, specifically is a kind of trailing arm of exempting to weld.

Background technology

Existingly be used for that various device is carried out supported and suspended trailing arm and generally form, generally be fixedly connected by welding between column and the cantilever by column and cantilever.The trailing arm of this structure is owing to need weld, and the efficient of its processing and manufacturing is lower, and product quality is difficult for guaranteeing, in addition, because the relative position between its cantilever and the column is fixed, can't regulate according to the needs of erecting stage, has brought inconvenience to use.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of need not to weld fixing, easy to process, can regulate cantilever height as required exempt to weld trailing arm.

Of the present utility modelly exempt to weld trailing arm and include column and cantilever; Column has the inner chamber of vertical perforation, and the back and the two sides of inner chamber are wallboard, and the front of inner chamber has the chute of vertical perforation, and the width of chute promptly forms the retaining eaves less than the width of inner chamber in the chute both sides; Cantilever has a top panel, a lower panel and is connected side panel between the upper and lower panel; The rear end of top panel is provided with a vertical web joint that leans against the chute outside of column, is provided with the sliding nut of a width greater than chute in the inboard of chute simultaneously, has a coupling bolt to pass web joint and chute and sliding nut and is connected; The rear end of lower panel is provided with the necking section that contracts in one section width, and this necking section places chute, makes whole cantilever can move and don't break away from column along vertical chute.

Back at above-mentioned sliding nut also can be fixedly connected with a compression spring, and the rear end of compression spring is pressed on the squab panel of column inner chamber, makes sliding nut can press close to chute, is convenient to bolt and connects.

Also can be provided with at an end of column and to be used for the installing plate that is connected with buildings, installing plate can be arranged on the lower end or the upper end of column according to the needs of actual installation.

This practicality is trapezoidal because cantilever and column are arranged to movable connection structure, overcome not only that the production efficiency that welding processing brings is low, the defective of unstable product quality, make that simultaneously the relative height of cantilever and column can free adjustment, thereby greatly facilitate on-the-spot the installation.

Fig. 1 is an one-piece construction synoptic diagram of the present utility model;

Fig. 2 is the structural representation of A section among Fig. 1;

Fig. 3 is the structural representation of B section among Fig. 1.

Embodiment

As shown in the figure, this is exempted to weld trailing arm and includes column 1 and cantilever 2.The inner chamber 3 that vertical perforation is arranged in the column, inner chamber front are the chute 4 that vertically connects, and there is retaining eaves 5 the chute both sides.Cantilever is made up of the top panel 6 of a level, lower panel 7 and vertical side panel 8 of an inclination.There is vertical web joint 9 the top panel rear end, is separated by retaining eaves 5 between web joint and the sliding nut in the column inner chamber 10, and is connected by coupling bolt 11, and the lower panel rear end has necking section 12, and necking section is stuck in the chute.Like this,, can realize the slidable adjustment of cantilever, behind the height and position of adjusting cantilever, can screw the tight bolt 11 of connection the stationkeeping of cantilever is lived along chute by coupling bolt and the structure of sliding nut and the necking down structure of lower panel that is connected with top panel.

This make easier for installationly, be fixedly connected with a compression spring 13 that is pressed on the inner chamber rear wall in the back of sliding nut 10, make sliding nut can press close to chute.In addition, also be provided with installing plate 14, be used for being connected with buildings in the end of column.

Claims
