Description
Technical field
The utility model is related to a kind of compound waterproof adhesive tapes for prefabricated components seam, belong to sealing element technical field.
Background technology
With becoming increasingly conspicuous for the contradictions such as population, resource, environment and social development space, development underground space structure into
For the grand strategy starting point resolved contradiction.Prefabricated component has many advantages, such as energy-saving and emission-reduction, environmentally protective, by assembled
It is also development trend that prefabricated components, which are applied to underground structure,.In existing technology, in the connection procedure between prefabricated components, connect
Water-proofing treatment at seam is always the problem for being solution, mostly using bonding waterproof adhesive tape, is reached by way of mechanical presses
The purpose of waterproof sealing.Therefore mainly meet the requirement of sealing performance by waterproof adhesive tape, the design of waterproof adhesive tape is shown
It obtains crucial.It is that line contacts or face contacts to seal that traditional sealing joint strip, which is typically designed as with the contact that connects, when the contact of adhesive tape
There is little particle dust or in the case where hydraulic pressure is larger in position, prefabricated components seam crossing or easily generation water inlet or leak shape
Condition, it is impossible to reach good waterproof sealing effect.
Invention content
In order to overcome the problems, such as that current existing waterproof adhesive tape is unable to reach preferable waterproof sealing effect, the utility model provides
A kind of compound waterproof adhesive tape for prefabricated components seam, the compound waterproof adhesive tape set pre- inlay, seal, it can be achieved that carrying
Waterproof sealing effect of waterproof adhesive tape is risen.
To solve the above problems, the utility model adopts the following technical solution：
（1）A kind of compound waterproof adhesive tape for prefabricated components seam is by EVA waterproof adhesive tapes ontology, groove, pre- inlay, close
Seal body composition.Groove of the EVA waterproof adhesive tapes equipped with horizontal indent, pre- inlay and seal are respectively by way of hot pressing
It is fixedly connected with groove.
（2）The pre- inlay is made of pre- embedding adhesive tape, bonding cavity, rubber cement, fixing end, and the fixing end passes through
The mode of hot pressing is connect with groove, and pre- embedding adhesive tape is fixedly connected in fixing end；The diameter at position is bigger among the pre- embedding adhesive tape
In pre- embedding adhesive tape both ends diameter, hollow bonding cavity is fixedly installed in pre- embedding adhesive tape right end；The thickness ratio of the cohesive cavity
The thickness for sealing molten chamber is small, bonds and rubber cement is equipped in cavity.
（3）The seal include sealing joint strip, sealed volume, fixing end, the fixing end by way of hot pressing with
Groove connects, and fixed connection and sealing adhesive tape in fixing end, the sealing joint strip is provided in the direction of pre- embedding adhesive tape in perforation
Empty sealed volume.
（4）At least ten groups of the quantity of the pre- inlay and seal；The material of the pre- inlay is addition polyethylene oxide
The water swelling rubber of water-absorbing resins；The material of the seal is silica-gel foaming-gel item.
The beneficial effects of the utility model are：A kind of composite water-proof for prefabricated components seam provided by the utility model
Adhesive tape, waterproof adhesive tape ontology, the pre- inlay of the utility model are different with the material of seal, can play composite water-proof effect.
When pre- inlay is placed in the annular seal space in seal, the different pre- embedding adhesive tape of diameter, which can extend, to be deformed and causes pre- inlay and sealing
Body can be more closely sealed, improves waterproof sealing effect；Furthermore because the material of pre- inlay is water swelling rubber, upon contact with water
Water volume is absorbed immediately to expand rapidly and be filled in seal cavity, is blocked, is cut off water stream channel and reach waterstop sealing effect；
The seal and sealed volume be made of silica-gel foaming-gel strip material to a certain extent, improves the slow of waterproof adhesive tape ontology
Rush ability；The rubber cement bonded in cavity adds somewhat to leakproofness.

Specific embodiment
In Fig. 1, a kind of compound waterproof adhesive tape for prefabricated components seam is by EVA waterproof adhesive tapes ontology, groove, pre- embedding
Body, seal composition.The EVA waterproof adhesive tapes（1）It is equipped with the groove of horizontal indent（2）, pre- inlay and seal lead to respectively
Cross the mode and groove of hot pressing（2）It is fixedly connected.The pre- inlay is by pre- embedding adhesive tape（3）, bond cavity（5）, rubber cement
（6）, fixing end（7）Composition, the fixing end（7）By way of hot pressing and groove（2）Connection, fixing end（7）Upper fixation is even
Connect pre- embedding adhesive tape（3）；The pre- embedding adhesive tape（3）The diameter at intermediate position is slightly larger than pre- embedding adhesive tape（3）Both ends diameter, in pre- embedding glue
Item（3）Hollow bonding cavity is fixedly installed in right end（5）；The cohesive cavity（5）Thickness ratio sealed volume（8）Thickness
It is small, bond cavity（5）It is interior to be equipped with rubber cement（6）.The seal includes sealing joint strip（4）, sealed volume（8）, it is fixed
