Description

The varnish board set screw

The utility model is about a kind of roasting Qi plate set screw, particularly, be meant a kind of by the groove of set screw and the members such as protrusion embedding portion of pad, the design that common composition can produce better antiseepage function, and can additionally save the cost of seepage control project.

Because modern's industrial level day by day improves, for the iron sheet room of putting up fast, be not afraid of earthquake, present market acceptance is very surprising, and varnish board set screw indispensable product when especially the iron sheet Corrugated roof plate being combined with steelframe, the variation very of at present general being seen varnish board set screw, still, because the restriction of Taiwan on climate, so whether the varnish board set screw has preferable percolation-proof effect, just becomes the characteristic that the Consumer payes attention to the most; Therefore, how to develop a kind of varnish board set screw that produces better antiseepage function, become the iron sheet room person of putting up and varnish board set screw MANUFACTURER already and want most several problems of overcoming, and the problem that is presented in the foregoing also to be the present utility model people research and develop motivation of the present utility model.

Traditional varnish board set screw, see also Fig. 1, shown in Figure 2, all need have head end 10 and screw rod 11, system is provided with a groove 12 on the inner face on these head end 10 corresponding screw lock mating faces, and these groove 12 2 side outer rim walls are plane of inclination 13, and the root edge of this groove 12 is a horizontal plane 14, and the pad 16 with a tool interior bone 15 is set on the screw rod 11 in addition, cooperates this pad 16 closely to be locked together on iron sheet Corrugated roof plate and the steelframe this head end 10 again; The varnish board set screw that this kind is commonly used is being sold on the market, is being used for a long time, but this kind design still has deficiency on percolation-proof effect, makes its effect unclear, and tracing it to its cause is to be:

One, see also shown in Figure 3, because of the screw rod 11 of traditional varnish board set screw can penetrate iron sheet Corrugated roof plate and steelframe, so head end 10, closely being pressure bonded to of screw rod 11 and pad 16 to important, the head end 10 of varnish board set screw commonly used is when this pad 16 of compressing, because these groove 12 2 side outer rim walls are plane of inclination 13, root edge is a horizontal plane 14, so the stress of head end 10 these pads 16 of compressing can form one outside stress when these pad 16 distortion, cause this pad 16 part when traditional varnish board set screw is oppressed outwards to extrude, and can be not closely knit fully be full of this groove 12, cause the breach of anti-seepage effect, originally has a complete hollow space because of this groove 12 in addition, when so this pad 16 is forced into, air is outwards expelled, also between this pad 16 and other structures, cause the gap that to seep water;

Its two, because of traditional varnish board set screw has the knuckle 17 that many inclined-planes intersections forms in head end 10 grooves 12, will when head end 10 these pads 16 of compressing, become the obstruction of these pad 16 compressive deformations;

They are three years old, see also shown in Figure 4 again, because pad 16 commonly used does not embed before operation in these head end 10 grooves 12, so slightly (most varnish board set screw all can have deflection in true operation during deflection if the varnish board set screw hammers into angle, but not fully vertical working surface hammers into), this pad 16 very easily under high pressure slides arbitrarily, and the situation that causes groove 12 not seal fully makes the situation of infiltration even more serious;

Its four because the infiltration situation of varnish board set screw commonly used is very many,, and make the seepage control project cost in iron sheet room improve so general dealer needs again in case strike-through spreads upon this head end 10 all sides after the varnish board set screw all hammers into.

Relevant the utility model is the technology of reaching above-mentioned purpose, being adopted, means and other effects, but now enumerate a preferable embodiment and cooperate graphic detailed description as after, believe the purpose of this utility model, feature and other advantages, when can by one deeply and concrete understanding; At first see also Fig. 5, shown in Figure 6, the utility model is made of jointly members such as a set screw 20 and pads 30, wherein:

This set screw 20, be one to have the screw of head end 21 and screw rod 22, system is provided with a groove 24 on the inner face 23 on set screw 20 corresponding screw lock mating faces, the outer rim wall 242 of these groove 24 sinking space 241 is a vertical surface, and the root edge 243 of these groove 24 sinking space 241 and inner edge 244 are cambered surface, and these set screw 20

grooves

24 and 22 of screw rod are provided with an inclined ring edge 25, and the periphery system with set screw 20 head ends 21 is set as umbrella inclined-plane 26 in addition;

This pad 30, it is the soft lamellar body of a tool interior bone 31, its sheet surface 32 is just to inner face 23 that should set screw 20, and groove 24 sinking space 241 systems that should set screw 20 are provided with an arcuation protrude embedding portion 33, and the volume of this protrusion embedding portion 33 is slightly larger than groove 24 sinking space 241 of this set screw 20, and the interior bone 31 of this pad 30 just to should set screw 20 grooves 24 and the inclined ring edge 25 of 22 of screw rod be provided with the narrower inclination face 34 that contracts; The above is the correlation position of each related elements of the utility model and the general introduction of structure thereof.

In order to clearly demonstrate flowing mode and the effect done of the present utility model, please cooperate again consult shown in Figure 7, when the utility model hammers into iron sheet Corrugated roof plate and steelframe at this set screw 20, the inner face 23 on these head end 21 corresponding screw lock mating faces can be to this pad 30 of lower compression, because the volume of the protrusion embedding portion 33 of this pad 30 is slightly larger than groove 24 sinking space 241 of this set screw 20, embedding is formed in groove 24 sinking space 241 of this set screw 20 so this pad 30 protrudes before the 33 not oppressed distortion of embedding portions, so groove 24 sinking space 241 do not have the air of accumulation, and the outer rim wall 242 of these groove 24 sinking space 241 is a vertical surface, and the root edge 243 of these groove 24 sinking space 241 and inner edge 244 are cambered surface, so utilize inclined ring edge 25 that this pad 30 is pressed to this outer rim wall 242 (carry over root edge 243 and inner edge 244 cambered surfaces are advanced) during these pad 30 pressurizeds, but because of outer rim wall 242 is to be vertical walls, can prevent this pad 30 unlikely outside distortion, and the distortion that makes this pad 30 is limited in the sinking space 241, so can produce more closely knit sealing effect; By above-mentioned action, this pad 30 of the present utility model can be formed in groove 24 sinking space 241 of this set screw 20 in embedding closely, has given play to better anti-ginseng function commonly used.

See also shown in Figure 8 again, embedding is formed in groove 24 sinking space 241 of this set screw 20 because this pad 30 protrudes before the 33 not oppressed distortion of embedding portions, so slightly (most varnish board set screw all can have deflection in true operation during deflection if set screw 20 hammers into angle, but not fully vertical working surface hammers into), this pad 30 still can embedding system be positioned at inner face 23 belows of this head end 21, so and be not easy under high pressure to slide arbitrarily, the sealing that can keep 21 of this pad 30 and this head ends prevents that infiltration from taking place; What deserves to be mentioned is, because the infiltration situation of the utility model varnish board set screw 20 is difficult for generation, thus use dealer of the present utility model to need not after varnish board set screw 20 all hammers into, to smear anti-strike-through, and make the seepage control project cost in iron sheet room reduce.

In addition, the utility model is set as umbrella inclined-plane 26 with the periphery system of set screw 20 head ends 21, so the periphery of set screw 20 head ends 21 can ponding, has more reduced the chance that infiltration takes place, so should belong to category of the present utility model together.
