Abstract
A combined water-stop split bolt belongs to clamp technical field, comprising a bolt and nuts on the both end of the bolt. The bolt is characterized in that a sleeve pipe and an internal screw joint with screw hole on the both end are provided, the both ends of the internal screw joint are connected with the bolt by screw, three grooves are arranged on the external surface of the internal screw joint; the middle groove is used to install water-stop piece, the grooves on the both side are used to embed seal ring. The sleeve pipe covers the bolt on the both sides of water-stop piece groove; the sleeve pipe mount and the seal ring are matched by inserted connection. The utility model has advantages of simple rational structure, easy production, low cost, easy application, work efficiency and construction quality enhancement, energy saving; and can be extensively used in template installation of water-proof concrete projection construction; the construction cost is remarkably reduced.
Description
Technical field
The utility model relates to the split bolt that is used for formboard fastening in the waterproof concrete engineering construction and the sealing sheet is installed, and belongs to technical field of tooling clamps.
Background technology
In the concrete product construction that waterproof requirement is arranged, as build water proof equipment bases such as concrete slab culvert wall, swimming pool wall, fire water pool wall, culverts and water gates underwater concrete part in the outer board wall of concrete of basement, the municipal engineering, all need to come the template of fastening concreting and the sealing sheet of waterproof is installed by split bolt.
The existing formboard fastening that is used for is installed the split bolt of sealing sheet again, generally be according to the width of concrete product self in constructing at the scene, process the bolt of single respective length, the sealing sheet that adds a slice Ф about 80 in the bolt middle part, adopt dead size between the welding short steel rod control template, directly be embedded in the concrete, it is fastening that the template both sides add plain nut with the butterfly clip.After finishing the concreting form removal, cut off exposed parts, recover outward appearance with the sand removal slurry, waterproofing course is done again according to design in the outside.The split bolt of existing field machining uses inconvenience, influence work efficiency, is embedded in concrete interior reinforcing bar, bolt and exposed parts and is consumed into scrap iron by bolt, has not only wasted former material but also lost labor, also can be because of the vibration influence engineering construction quality that cuts off.
The utility model content
The purpose of this utility model is to provide a kind of both easy to use, improves work efficiency and construction quality, the combined type sealing split bolt that economizes on resources again.
The purpose of this utility model is to realize like this, combined type sealing split bolt, comprise bolt and spin and be fastened on the nut of bolt two outer ends, it is characterized in that being provided with the female adapter of sleeve pipe and two ends band screw, the two ends spiral connecting bolt of female adapter, the external surface of female adapter is provided with three road grooves, middle is that the sealing film trap is installed, embedded sealing ring in the groove on both sides, sleeve pipe are nested with on the bolt of sealing film trap both sides, and sleeve opening and sealing ring are pegged graft and mated.
The two ends of described bolt are respectively equipped with greater than 0.08 meter long and screw thread nut coupling.5 millimeters thick next doors are arranged between the screw at female adapter two ends.Described sleeve pipe is a plastic pipe, and sleeve end is provided with horn mouth.
When adopting the utility model to be used to the concrete product construction of waterproof requirement is arranged, can in the sealing film trap in the middle of the external surface of female adapter the sealing sheet be set earlier, the sealing sheet can be sheet metal or other fluid-tight material, can connect with welding, also can be fixed in the sealing film trap.Setting-in rubber seal in the groove on both sides, the two ends spiral connecting bolt of female adapter.Sleeve pipe is nested with on the bolt of sealing film trap both sides, and sleeve opening and sealing ring are pegged graft and mated, and prevent that concrete, mortar from entering sleeve pipe, are provided with a bell-mouthed end and outwards are used to withstand template.Template outside attaching nut is stretched out at the two ends in addition of bolt respectively.Cushion block, steel pipe, butterfly folder are set between template and the nut, screw nut and tighten up template.When concrete product has been built form removal, screw off bolt, reusable.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and is easy to use, improves work efficiency and construction quality, economizes on resources, and can significantly reduce construction cost.
