Description
Technical field
The utility model relates to the connection fastening piece, is bolt assembly specifically, especially a kind of leakage proof bolt assembly.
Background technique
Being used for the factory building roofer is fixed on the support supporting with it and realizes by bolt assembly.The bolt assembly that is used for fixing roofer divides two kinds of fixing bolt assembly (model is ML850R) and connecting bolt assemblies (model is R-8).
The ML850R fixing bolt is assembled by bolt 11, plastic washer 12, thin wall casing 13, concavo- convex packing ring 14 and 15 5 kinds of parts of seal washer, is mainly used in being connected between roofer and the support, and concrete structure is seen shown in Figure 1.
The centre of ML850R fixing bolt assembly is a common M8 bolt 11, the outside is a thin wall casing 13 that has four even grooves; thin wall casing 13 bottom tapping; bolt 11 and thin wall casing 13 pass roofer and support, plastic washer 12, concavo-convex packing ring 14 and seal washer 15 are successively between the spiral shell head and roofer of bolt 11.When bolt 11 usefulness electric wrenches screwed, the thin wall casing of being cut apart by four grooves 13 opened with regard to oneself and withstands support and play fastening effect, as shown in Figure 2.
R-8 connecting bolt assembly is assembled by screw rod 21, nut 22, concavo-convex packing ring 23, seal washer 24, plastic bushing 25,26 6 kinds of parts of wabbler, is mainly used in being connected between roofer and the roofer, and concrete structure is seen shown in Figure 2.
The characteristics of above-mentioned two kinds of bolt assemblies are to construct by single face, do not need scaffolding to carry out inside and outside operation.But when requiring construction, can open automatically these two kinds of bolt assemblies at fastening thin wall casing 13 down of electric wrench or wabbler 26.Therefore, the selected steel of these two kinds of parts can not be too hard, fitness for purpose low carbon steel.And these two kinds of bolt assembly complex structures are made difficulty.
Because the part of above-mentioned two kinds of bolt assemblies exists the qualification that material selects for use and the restriction of processing technology, so the part of bolt assembly can't substitute with material that can the acidic fog resistance corrosion.Like this, only abutment surface is zinc-plated realizes that effect is bad for the anticorrosive measure of bolt assembly.Use under strong corrosive medium, the life-span of bolt assembly is shorter.In addition because the wall of the concavo- convex packing ring 14,23 on these two kinds of bolt assembly tops is all thinner, under the sun, is exposed to the sun or exposes to the sun and rain concavo- convex packing ring 14,23 very easily corrosions for a long time.And, just making seal washer 15,24 be directly exposed in the air in case concavo- convex packing ring 14,23 corrosions are rotted, not long seal washer 15,24 will wear out and cause the forfeiture waterproof performance time.In addition, the fastening force of above-mentioned two bolt assemblies mainly realizes that by the elastic force after 25 distortion of thin wall casing 13 and plastic bushing this part material walls is very thin, and very easily corrodes (the interior outside all contacts in the external world), in case corrode, its fastening force is affected at once even loses.
The model utility content
The purpose of this utility model is to provide that a kind of fastening force is good, locking, the leakage proof bolt assembly of leakage proof.
To achieve these goals, a kind of leakage proof bolt assembly that the utility model provides, comprise bolt, be enclosed within packing ring, gasket seal on the screw rod of bolt successively, concavo-convex packing ring and nut, it is characterized in that: described bolt is the straight-bar clamping bolt, is being provided with spring washer on the screw rod of bolt between concavo-convex packing ring and nut.
This bolt assembly is when fastening building roofing plate, the screw rod of bolt is upward through two-layer roofer or support and one deck roofer, wherein spiral shell head, the packing ring of bolt are positioned at the below of lower floor's roofer or support, gasket seal, concavo-convex packing ring, spring washer are enclosed within the top that is positioned at the upper strata roofer on the screw rod of bolt successively, and nut screws.Bolt adopts the straight-bar clamping bolt, and fastening force is strengthened greatly; Lockingly realize that waterproof realizes in conjunction with concavo-convex packing ring by seal washer by spring washer.
After treating that bolt assembly has been connected and fixed the building roofing plate, in order further to solve the corrosion and the sealing problem of bolt assembly, in further improvement of the utility model, also increasing has the corrosion protection tarpaulin, and corrosion protection waterproof calotte is combined on seal washer, concavo-convex packing ring, spring washer and the part screw rod.
Therefore, the existing relatively bolt assembly of leakage proof bolt assembly of the present utility model has that fastening force is good, locking, a leakage proof, etch-proof advantage, and easy construction simultaneously both can be used for roofer is fixed on the support, can be used for the connection between the roofer again.

Embodiment
As Fig. 5 and in conjunction with shown in Figure 8, leakage proof bolt assembly of the present utility model comprises bolt 31, packing ring 32, gasket seal 33, concavo-convex packing ring 34, spring washer 35, nut 36.
Cover upper gasket 32 on the screw rod 311 of bolt 31, passing support 8 and roofer 7 (Wave shape roof plate) in building successively stretches out outside the building, gasket seal 33 then, concavo-convex packing ring 34, spring washer 35, nut 36 outside the building are enclosed within on the screw rod 311 of bolt 31 successively, are fastened on the support 8 up to roofer 7 with the continuous turn-knob nut 36 of electric wrench.At this moment the spiral shell head 312 of bolt 31 and packing ring 32 are positioned at the below of the support 8 of building, gasket seal 33, and the part of concavo-convex packing ring 34, spring washer 35, nut 36 and screw rod 311 is exposed at the top of the outer roofer 7 of building.
This wherein, packing ring 32 is a plain washer.Bolt 31 is the straight-bar clamping bolt, has very strong fastening force, and the material of bolt 31 adopts corrosion resistance 316 stainless steels relatively preferably, has good anti-corrosion.Gasket seal 33 is the butyl type rubber pad, is used for realizing waterproof action with concavo-convex packing ring 34 combinations.Spring washer 35 is used to realize locking effect: after bolt assembly is fastening because of the Wave shape roof plate in the distortion that is subjected to produce under the external force effect, loosening can solve by this spring washer 35.
In order further to solve the corrosion and the sealing problem of bolt assembly, this leakage proof bolt assembly has also increased corrosion protection tarpaulin 37, as Fig. 6 and Fig. 7.Materials such as this corrosion protection tarpaulin 37 usefulness PVC or glass fibre reinforced plastics are made, and are used to cover on the exposed parts of this bolt assembly, promptly cover on gasket seal 33, on the screw rod 311 that concavo-convex packing ring 34, spring washer 35, nut 36 and part expose.After cover was good, waterproof gasket cements such as employing silica gel were obturaged corrosion protection tarpaulin 37.This corrosion protection tarpaulin 37 has been arranged, and very natural, water and corrosive material just are difficult to enter bolt assembly part are corroded, thereby this leakage proof bolt assembly waterproof, etch-proof performance are improved greatly.
It more than is exactly leakage proof bolt assembly of the present utility model, this bolt assembly is except the above-mentioned advantage that has, it is also extremely convenient to install, the same with plain bolt, do not have specific (special) requirements, fastening effective success rate improves greatly than existing bolt assembly, and both has been applicable to roofer is fixed on the support, be applicable to the connection between the roofer again, need two kinds of bolt assemblies like that and need not prior art.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model the above embodiment's variation, distortion.
