Abstract

The utility model discloses a tower crane standard knot. The tower crane standard knot comprises four main chord members, diagonal web members, cross members and connecting sleeves, wherein the main chord members are made of square steel; the connecting sleeves are welded on two nonadjacent side edges of the end parts of each main chord member; the cross members are welded between two ends and centers of two adjacent main chord members so as to form the cuboid standard knot; the diagonal web members are welded on a diagonal of an upper surface and a lower surface of the standard knot and the diagonal of two cross members at the side surface of the standard knot; the welding surfaces of the connecting sleeves and the main chord members are provided with grooves; in welding, the side edges of the main chord members cling into the grooves, so that the welding is tight. According to the utility model, the square steel is adopted for manufacturing the standard knot, the welding technology is simple, and the deformation is easy to control; bonding surfaces are high in rigidity, a weld joint is good in quality, and the intensity is higher; two ends of the square steel of the manufactured standard knot are both of seal structures, so that the anticorrosion capability of a steel structure is improved, and the service life of the steel structure is prolonged.

Description

Standard section of tower crane

Technical field

The utility model relates to a kind of standard section of tower crane, belongs to mechanical technical field of buildings.

Background technology

Standard section of tower crane is the important component part of a tower crane, it not only will bear work load, the load of tower body topside deadweight, wind loading, but also want the normal operation of support tower body framing member and mechanism, along with the continuous rising of building, standard knot also will constantly increase height, the vertical transport that raises to adapt to building, so standard knot will constantly improve its enough rigidity, strength and stability.

The utility model content

The utility model provides a kind of standard section of tower crane, and welding process is simple, distortion easy to control, and faying face good rigidly, and weldquality is good, and intensity is higher.

The technical solution adopted in the utility model is:

Standard section of tower crane, comprise main chord, diagonal web member, cross bar and adapter sleeve, described main chord has 4, is made by square steel, be welded with adapter sleeve on non-conterminous two inclines in the two ends of described every main chord, described cross bar has 12, is welded in respectively between the two ends of adjacent 2 main chords and between the center, consists of the standard knot of cuboid; Described diagonal web member has 10, is welded in respectively on a diagonal line of standard knot upper and lower surface and the diagonal position of two cross bars of standard knot side; An end face level of described adapter sleeve, another end face has a projection, the face of weld of adapter sleeve and main chord is fluted, during welding, the incline of main chord is close in groove, make welding closely, the centre of described adapter sleeve is porose, by tightening screw, the adapter sleeve of two standard knots in up and down is fixed.

The end face of aforesaid main chord seals by bloom.

When aforementioned adapter sleeve was welded in the lower end of main chord, the end face of the end face of adapter sleeve level and the lower end of main chord was on same level, and bossed end face up.

When aforementioned adapter sleeve was welded in the upper end of main chord, the end face of the end face of adapter sleeve level and the upper end of main chord was on same level, and bossed end face down.

After having adopted technique scheme, the beneficial effect that the utility model compared with prior art has is: adopt square steel production standard joint, welding process is simple, distortion easy to control; The faying face good rigidly, weldquality is good, and intensity is higher; The standard knot that completes, its square steel two ends are hermetically-sealed construction, improve the steel structure resistance to corrosion, extend its service life.

The specific embodiment

Describe the utility model in detail below in conjunction with the drawings and specific embodiments.

So as Fig. 1, standard section of tower crane of the present utility model comprises main chord 1, diagonal web member 2, cross bar 4 and adapter sleeve 3, described main chord 1 has 4, is made by square steel, be welded with adapter sleeve 3 on non-conterminous two inclines in the two ends of described every main chord 1, described cross bar 4 has 12, is welded in respectively between the two ends of adjacent 2 main chords and between the center, consists of the standard knot of cuboid; Described diagonal web member 2 has 10, is welded in respectively on a diagonal line of standard knot upper and lower surface and the diagonal position of two cross bars of standard knot side.

As described in Figure 2, an end face level of adapter sleeve 2, another end face has a projection, the face of weld fluted 5 of adapter sleeve 2 and main chord 1, during welding, the incline of main chord 1 is close in groove 5, is made welding closely, the centre of described adapter sleeve 2 is porose 6, by tightening screw, the adapter sleeve of two standard knots in up and down is fixed.

As shown in Figure 3, main chord is made by square steel, and its end face consists of hermetically-sealed construction by bloom 7 sealings, improves the steel structure resistance to corrosion, extends its service life.

As shown in Figure 4, when adapter sleeve 3 was welded in the upper end of main chord 1, the end face of the end face of adapter sleeve 3 levels and the upper end of main chord was on same level, and bossed end face down.

When adapter sleeve 3 was welded in the lower end of main chord 1, the end face of the end face of adapter sleeve 3 levels and the lower end of main chord was on same level, and bossed end face up.

Abovely basic conception of the present utility model and groundwork have been set forth by better embodiment; but the utility model never is limited to above-mentioned listed embodiment; every equivalent variations or improvement of doing based on the technical solution of the utility model all should belong to protection domain of the present utility model.
