Abstract

The invention discloses an H-type steel socket spanner which comprises a steel tube, a nut sleeve and a handle. The nut sleeve is a hexagonal socket nut sleeve, and the hexagonal socket nut sleeve is sleeved with a lower opening of the steel tube to be installed, welded and fixed; a handle body of the handle transversely penetrates through a left penetrating opening and a right penetrating opening formed in the upper end of the steel tube, and the sizes of the two ends of the handle body are larger than the sizes of the left penetrating opening and the right penetrating opening. By means of the H-type steel socket spanner, adverse effects of H-type steel structural characteristics on bolt installation are overcome, so that the bolt screwing process is smoothly implemented when a steel column and a steel beam are pre-assembled or initially installed.

Description

H shaped steel box spanner

(1) technical field:

The present invention relates to building trade erecting tools, be specially a kind of H shaped steel box spanner.

(2) background technology:

Along with engineering construction industry Installation Technology constantly advances, steel structure node connects and more and more to require to have fatigue resistance, and the important node trend such as post beam connects and replaces being welded to connect with high-strength bolt.

Bolt hole borehole accuracy requires high, and modern designs beam column connects requirement cover conventionally and bores, and requires beam column assembled in advance, in pre-splicing process of assembling, uses interim construction bolt to connect.

Due to restriction and the H shaped steel feature of execution conditions, often use less than electric wrench, on market, be also difficult to buying to suitable box spanner, and be mainly to use manual wrench to tight a bolt.Because girder steel mostly is the manufacture of H shaped steel, some depth of sections are too small, and spanner cannot operate, and the bolt tightening operation that is exactly in addition web and flange plate junction cannot be implemented, or can only low-angle construction, inefficiency and do not reach requirement.

(3) summary of the invention:

For this reason, the present invention proposes the bolt tightening H shaped steel box spanner that everything goes well with your work implements on a kind of H of making shaped steel.

The technical scheme of H shaped steel box spanner of the present invention, comprises steel pipe, hexagonal socket nut cover and handle, and it is fixing that difference is that described hexagonal socket nut is placed in steel pipe end opening suit; The handle body of described handle crosses the left and right mouth that wears of offering in steel pipe upper end, and for preventing that handle from coming off, the handle body two ends size of handle is greater than the left and right mouth that wears.

Described hexagonal socket nut cover adopts welding with the fixed form of steel pipe, and described hexagonal socket nut cover end face is concordant with steel pipe end opening end face and offer groove, and welding position is between the groove and steel pipe end opening inwall of hexagonal socket nut cover.

According to hexagonal socket nut cover specification and site space situation, the choice of diameter of described steel pipe is ￠ 50mm～￠ 80mm, and the thickness of pipe is chosen as 3mm～5mm, and length is chosen as 300mm～800mm.

Described hexagonal socket nut cover is corresponding to the nut of different size specification, and spanner of the present invention is made to series.

Beneficial effect of the present invention:

H shaped steel box spanner of the present invention has overcome the adverse effect that H formed steel construction feature is installed bolt, makes steel column and girder steel pre-assembled or while just filling, bolt tightening operation is implemented smoothly.Reached following effect:

1, save manually, a people can independent operation substantially.

2, small and exquisite flexible, easy operating is controlled.

3, spanner is of moderate size, and is convenient to carrying, is applicable to the bolt tightening work of various orientation.

4, because bolt or nut are standard component, specification is certain, can produce spanner by batch according to dimension, also can be at the construction field (site) according to the existence conditions making spanner of gathering materials on the spot.

(4) accompanying drawing explanation:

Fig. 1 is the structural representation of one embodiment of the present invention.

Fig. 2 is that A in Fig. 1 is to view.

Fig. 3 is the batch production structure chart of Fig. 1 embodiment.

Figure number sign: 1, steel pipe; 2, hexagonal socket nut cover; 3, handle; 4, power transmission sleeve; 5, ut socket; 6, connecting rod.

(5) specific embodiment:

Below in conjunction with accompanying drawing illustrated embodiment, technical scheme of the present invention is described further.

H shaped steel box spanner of the present invention has two schemes.

1, field fabrication scheme:

H shaped steel box spanner of the present invention comprises steel pipe 1, hexagonal socket nut cover 2 and handle 3, according to the specifications and models of hexagonal socket nut cover 2, the choice of diameter of described steel pipe 1 is ￠ 50mm～￠ 80mm, the thickness of pipe is chosen as 3mm～5mm, pipe range is chosen as 300mm～800mm, after steel pipe 1 cutting, upper and lower port polishes smooth, as shown in Figure 1.

With steel plate, make hexagonal socket nut cover 2, it is consistent with height of nut that hexagonal socket nut overlaps 2 thickness, interior hexagonal is by nut profiles setting-out cutting, the interior hexagonal length of side and overall dimensions are advisable just to stick into nut non-loosening, outer ring is slit into circle, diameter is equal to or slightly less than the internal diameter of steel pipe 1, reach and fill in the interior object of steel pipe 1, and overlap and on 2 end face circumference, offer a circle groove at hexagonal socket nut, after the lower end endoporus suit of hexagonal socket nut cover 2 and steel pipe 1, alignment hexagonal socket nut overlaps 2 end faces and steel pipe 1 end face, between the groove of hexagonal socket nut cover 2 and steel pipe 1 inwall, weld, and by burr, the polishing of splashing is clean, as Fig. 1, shown in Fig. 2.

In the position apart from steel pipe 1 upper end 50mm～200mm, with burning torch, split left and right wear mouthful (hole) for diameter of phi 31, the perforation of putting forth effort as handle 3, Φ 30 round steel of cutting 500mm length are as handle 3, handle 3 is made wedge by two ends with sledgehammer hammer after penetrating the perforating of steel pipe, makes handle 3 unlikely from landing in perforating; Described handle 3 can be used as the arm of couple and uses or use as single armed, also can use in addition steel cylinder as sleeve, to increase the length of handle 3, to reduce workmen's active force, as shown in Figure 1.

2, batch production scheme:

H shaped steel box spanner of the present invention comprises handle 3, power transmission sleeve 4, connecting rod 6 and ut socket 5, according to different nut specifications, make corresponding ut socket 5 and become series, described connecting rod 6 adopts steel-casting, length is chosen between 300mm～800mm, connecting rod 6 upper ends are made as male joint form, and corresponding described power transmission sleeve 4 bottoms are made as female joint form, and connecting rod 6 lower ends are made as female joint form, corresponding ut socket 5 upper ends are made as male joint form, as shown in Figure 3.

H shaped steel box spanner uses after being assembled by handle 3, power transmission sleeve 4, connecting rod 6 and ut socket 5: the male joint of female joint socket connecting rod 6 upper ends of described power transmission sleeve 4 bottoms, the female joint of male joint socket connecting rod 6 lower ends on described ut socket 5 tops, as shown in Figure 3.
