Abstract
The utility model discloses a caulking template for concrete backfill of a preformed hole in a pipeline. The caulking template is composed of two half templates, each half template comprises a support board (1) and a vertical board (3), one side of each end surface of each support board (1) protrudes, the other side of the end surface of the support board (1) is shortened correspondingly, and the two end surfaces of each support board (1) are not aligned with two end surfaces of the vertical board (3). After the two half templates are mounted, a staggered position (5) is formed at the butt joint position of the support board (1) and the vertical board (3) to form a step (4), the extrusion force between two surfaces which form the step is used to achieve the sealing effect, silicate substances mixed in water which oozes from the backfilled concrete are prevented from flowing along the butt joint surfaces to contaminate and corrode a screw or a clamp in a fastening screw hole (6) in a reinforced rib (2), the caulking template can be dismounted and mounted conveniently, and the service life of the caulking template is prolonged.
Description
Technical field
The utility model relates to a kind of pipeline preformed hole fill concrete filleting template, belongs to the chemical building material technical field.
Background technology
In early days, building field is to adopt plank to dig to make two semicircle templates to be buckled on the pipeline and with iron wire to hang the jail to the shutoff of pipeline preformed hole again, realizes by support, the fill concrete of plank; The weak point of this way is: field fabrication wooden model occupied ground, lost labor, inefficiency, and also wooden model generally can not or can only reuse by limited number of time the waste material because of corrosion-resistant.
Afterwards, the Chinese patent (patent No.: 03215375.9,200720072691.1,200920156052.2) announced respectively a kind of floor pipe pre-arranged holes plugging mould plate, adopted plastics or ferrous materials injection moulding, casting to process.This product has advantages of simply, practical, mounting or dismounting are convenient, with low cost, also can be made into series, satisfies the various outer diameter pipeline needs are installed; So be widely used at building field, obtained preferably effect.But in the practical application, the template of above-mentioned three Patent designs is because supporting plate, riser are semicircle; The inevitable slit that produces between the interface after installing makes that the molten silicate material that is mixed with oozes out in the fill concrete, stains to connect trip bolt or clip; Because the corrosivity of silicate material is very strong, meeting heavy corrosion trip bolt causes the secondary dismounting and uses difficulty.
Summary of the invention
The purpose of this utility model is to design a kind of new pipeline preformed hole fill concrete filleting template, and the Steps that utilizes supporting plate and riser interface place to form is realized sealing, the silicate material of avoiding exosmosing corrosion trip bolt, and the guarantee template is used for a long time.
The utility model is achieved through the following technical solutions: the filleting template by two separation half template be formed by connecting by plain screw, the shape of two and half templates, structure, size design are identical.Comprise supporting plate (1), riser (3), reinforcing rib (2) on every half template, wherein two semi-circular cross-section one sides of supporting plate (1) are protruded, and the corresponding shortening of opposite side is with the concordant cross section of riser (3) 4-8mm that staggers; Behind the two and half template abutting joints, the in twos interface of supporting plate (1) and riser (3) 4-8mm that staggers produces a dislocation (5), forms a step (4); And the interface of the position, trip bolt hole (6) on dislocation (5) and the reinforcing rib (2) also can stagger.
The filleting template of the utility model design, its supporting plate (1) upper surface is designed to slight elliptic arc sunk structure (7); After this structure can guarantee that template installs, the upper surface of its supporting plate (1) and the soffit of ceiling were fitted complete.
The filleting template of the utility model design, the internal diameter of its semicircle supporting plate (1), riser (3) is compared approximately little 0.1-0.5mm with its fastening isonomic outer diameter tube; After this structure can guarantee that template installs, supporting plate (1) can tightly bind round on pipeline, has increased frictional force, came off because of the excessive template that causes of exerting oneself when avoiding flattening fill concrete.
The filleting template of the utility model design can be by PVC-U, PP, PE, ABS thermoplastic injection mo(u)lding processing and manufacturing.
The utility model has the advantage of: the first, the dislocation (5) that supporting plate (1) and riser (3) form at interface place in twos produces a step (4), relies on the extruding force between two faces of this step to realize sealing; Avoid the molten silicate material that is mixed with in the fill concrete water seepage, flow down along interface, stain, corrode screw or clip in the trip bolt hole (6) on the reinforcing rib (2), make things convenient for the dismounting of template; Prolonged template application life, simple and reliable for structure, effect is better.The second, supporting plate (1) upper surface is designed to slight elliptic arc sunk structure (7), avoids the slight convex that may exist on the ceiling, causes interface applying imprecision; The 3rd, the internal diameter of semicircle supporting plate (1), riser (3) has improved screw fastening power greatly less than its fastening isonomic outer diameter tube during installation; Standpipe and pipeline frictional force are obviously increased, avoid in use unexpected landing of template.

The specific embodiment:
Fig. 1-4 has provided a kind of embodiment of the present utility model.The filleting template by two separation half template be formed by connecting by plain screw, the shape of cope and drag pattern plate, structure, size design are identical; Adopt PVC-U, PP, PE or ABS thermoplastic injection mo(u)lding processing and manufacturing, mould can be designed as a cavity per mould, two chambeies or multi-cavity.Be applied to the filleting template that Φ 110 * 3.2 meets the supporting installation of GB/T5836.1 hard polyvinyl-chloride drainage pipe for building: design semicircle supporting plate (1) internal diameter 110.0mm, external diameter 180mm, cylindrical end thickness 3.5mm, dislocation (5) one sides are protruded 5mm, the corresponding shortening of opposite side 5mm; Design semicircle riser (3) internal diameter 110.0mm, wall thickness 3.5mm, the high 30mm of being; Every half template arranges three reinforcing ribs (2), and reinforcing rib (2) wall thickness is 5mm, and opening diameter on the interface place reinforcing rib is position, Φ 7.5mm hole, is used for installing trip bolt.
