Description

A kind of support post

Technical field

The utility model relates to a kind of support post that uses in building trade.

Background technology

In building trade, generally use support post to support weight as the adjustable supports body, at present, traditional support post comprises outer tube mostly, be set with internal overarm support in the outer tube, the upper outside of outer tube is bolted with adjusting nut, internal overarm support is provided with pin-and-hole, be furnished with the hook pin that can insert in the pin-and-hole on the support bar, during use, reach the coarse adjustment of bearing height earlier by the cooperation of hook pin and pin-and-hole, and then carry out the fine tuning of bearing height by the rotation of adjusting nut, because easy to use, use extensively in building trade, but the weak point of this support post is: adjusting nut directly is screwed onto with outer tube, there are not safeguard procedures, screw thread is directly exposed in the air, accumulates dust easily, influences the use of support post, especially when supporting precast concrete, stop up thread pitch when leaking under the cement paste easily, make troubles for the secondary use of support post, even can not use.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of thread pitch that stops up simple in structure, difficult at above-mentioned deficiency, can nonexpondable support post.

For solving the problems of the technologies described above, this support post, comprise outer tube, be set with internal overarm support in the outer tube, the upper outside of outer tube is bolted with adjusting nut, internal overarm support is provided with pin-and-hole, is furnished with the hook pin that can insert in the pin-and-hole on the support bar, and its design feature is: the upper end of outer tube and adjusting nut is equipped with the pad around internal overarm support.

The upper end of outer tube and adjusting nut is equipped with after the pad around internal overarm support, no matter be dust on the building site or the cement paste that leaks at present at the support precast concrete, all can't enter thread pitch from the upper end of outer tube and adjusting nut, and described dust and cement paste are almost nil from the probability that the adjusting nut lower end enters thread pitch, so, this structure design can effectively guarantee the clean cleaning of thread pitch, guarantees that adjusting nut rotation when fine setting is unobstructed.

As improvement, gather on pad in order to prevent dust or cement paste, described pad is the bowl-shape of back-off.

Because pad is the bowl-shape of back-off, that is to say, pad is local high near internal overarm support, and local low away from internal overarm support, so after dust or cement paste are fallen on the pad, under the effect of self gravitation, nature from the centre of pad to around landing, significantly reduced dust or the cement paste accumulated amount on pad, made cleaning easily simple more.

As further improvement, for the ease of construction, the lower end of outer tube is provided with lower roof plate, and the upper end of internal overarm support is provided with upper plate.

Support post generally is used for the stable support weight, the strength of bearing is bigger, in order to prevent to carry the sinking of ground of support post, the lower end of outer tube is provided with lower roof plate, in order to fall on the supporting surface that prevents the support post support, the upper end of internal overarm support is provided with upper plate, so just need not to place the support backing plate at the upper and lower side of support post, makes construction simpler, convenient.

As further improving again, rotate adjusting nut for convenience, be provided with the adjusting handle in the outside of adjusting nut.

Regulate the setting of handle, increased the turning moment of swivel nut, make when rotating adjusting nut convenient light.

In sum, adopt the support post of this structure, simple in structure, the difficult thread pitch that stops up can repeatedly use, and is particularly suitable for using in building trade, is particluarly suitable for using in the abominable building trade of construction environment.

Description of drawings

In conjunction with the accompanying drawings the utility model is described in further detail:

The structural representation of support post when Fig. 1 is off working state;

Fig. 2 is the structural representation of hook pin;

The structural representation of support post when Fig. 3 is duty.

Among the figure: 1 is outer tube, and 2 is internal overarm support, and 3 is adjusting nut, and 4 is pin-and-hole, and 5 is hook pin, and 6 is upper plate, and 7 is lower roof plate, and 8 is pad, and 9 for regulating handle.

The specific embodiment

As shown in the figure, this support post comprises outer tube 1, be set with internal overarm support 2 in the outer tube 1, internal overarm support 2 is provided with pin-and-hole 4, can support different height in order to make support post, and internal overarm support 2 is evenly equipped with a plurality of pin-and-holes 4 on its length direction, in the present embodiment, the quantity of pin-and-hole 4 is 4, is furnished with the hook pin 5 that can insert in the pin-and-hole 4 on the support bar 2, in use comes off in pin-and-hole in order to prevent hook pin 5, hook pin 5 is arranged to the bail shape, as shown in Figure 2; The outside of outer tube 1 is cylindric, the upper outside of outer sleeve 1 is bolted with adjusting nut 3, adjusting nut 3 mainly plays the fine setting effect, the top height that makes internal overarm support 2 when the cooperation by hook pin 5 and pin-and-hole 4 is during near the demand height, rotate up adjusting nut 3, adjusting nut 3 just passes through hook pin 5 with internal overarm support 2 slow jack-up, till the height of internal overarm support 2 upper ends reaches the demand height, rotate adjusting nut 3 for convenience, the outside of adjusting nut 3 is equipped with regulates handle 9; Hinder adjusting nut 3 in order to prevent dust or cement paste from falling into the thread pitch of adjusting nut 3 and rotate, the upper end of outer tube 1 and adjusting nut 3 is equipped with the pad 8 around internal overarm support 2, and pad 8 is positioned at the upper end of outer tube 1 and adjusting nut 3; In order to prevent that foreign material such as dust and cement paste from gathering on pad 8, pad 8 is designed to the bowl-shape of back-off, like this after the design, when dust or cement paste are fallen on the pad 8, dust or cement paste just are slipped on the ground on the inclined plane of the bowl-shape pad 8 in self gravitation effect lower edge, significantly reduced the time that dust or cement paste stop on pad 8, cleaning and dismounting support post all have been of great benefit to; Support post generally is used for for a long time stably supporting weights such as cement prefab, the strength that support post bears is bigger, in order to prevent to carry the sinking of ground of support post, be installed with lower roof plate 7 on the lower surface of outer tube 1, the area of lower roof plate 7 connects much bigger than the cross section of outer tube 1, can disperse stressedly, effectively prevent the sinking of ground phenomenon; As a same reason, in order to prevent that internal overarm support 2 upper ends are because of stressed excessive being absorbed in the still undried cement prefab, be installed with upper plate 6 on the upper surface of internal overarm support 2, the area of upper plate 6 is more much bigger than the upper surface area of internal overarm support 2, can disperse stressed, thereby prevent the phenomenon of caving in, like this design after, just need not to place and support backing plate, make that construction is simpler, materials are more economized at the upper and lower side of support post.
