It should be understood that the drawings of the present application are only used to match the contents disclosed in the specification, so as to be known and read by those skilled in the art, and not to limit the practical limitations of the present invention, so that the present application does not have any technical significance, and any modification of the structure, change of the ratio relationship, or adjustment of the size should still fall within the scope of the present application without affecting the function and the achievable purpose of the present application. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle", and the like used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be considered as the scope of the present invention without substantial changes in the technical content.
Example (b):
a novel pre-buried multi-functional PVC pipe stagnant water connects, includes PVC pipe straight joint 1, PVC stagnant water ring 2, fixed orifices 3, staple 4. The lower part of the PVC pipe straight joint 1 is embedded in the concrete floor 7, the upper part of the PVC pipe straight joint extends out of the upper part of the surface of the concrete floor 7, the PVC pipe straight joint 1 is processed by a factory mould, the inner diameter of the PVC pipe straight joint 1 is consistent with the outer diameter of a designed drain pipe, and the upper end interface 5 of the PVC pipe straight joint 1 is 100mm higher than the surface of the concrete floor 7, namely, the length of the PVC pipe straight joint 1 is = the thickness of the concrete floor 7 plus the extension of the PVC pipe straight joint 1 on the upper part of the concrete floor 7 by 100mm, so that the PVC pipe is convenient to bond, the bonding quality of the PVC pipe is; the pipe wall thickness of the PVC pipe straight joint 1 is 4.2mm, so that the quality of the PVC pipe straight joint 1 is ensured, and the PVC pipe straight joint 1 is prevented from being damaged in the concrete pouring process; the upper end interface 5 of the PVC pipe straight joint 1 is detachably plugged by cloth or a film or a cover (in the embodiment, the transparent adhesive tape is used for plugging), and the lower end interface 6 of the PVC pipe straight joint 11 extends out of the lower surface of the concrete floor 7. PVC seal ring 2 is fixed on the lateral surface of 1 lower part of PVC pipe straight joint and pre-buried in concrete floor 7 (PVC seal ring 2 is fixed on the position that 1 lower part lateral surface of PVC pipe straight joint is located concrete floor 7 middle part) for bury stagnant water in concrete floor 7 underground, PVC seal ring 2 diameter equals PVC pipe straight joint 1 diameter plus 100mm, PVC seal ring 2 thickness 4.2mm, in order to ensure when the concrete vibrates, be difficult for destroying PVC seal ring 2. The fixing holes 3 are two symmetrical and vertical threaded holes formed in the outer side surface of a lower end interface of the PVC pipe straight joint 1 (the outer side surface of a lower end interface 6 of the PVC pipe straight joint 1 is provided with two symmetrical anchoring points, each anchoring point is provided with one fixing hole 3 for fixing the PVC pipe straight joint 1, the position of the PVC pipe straight joint 1 is calibrated before fixing, and the axis deviation is not larger than 2 mm), so that the PVC pipe straight joint 1 is fixed on a template, the error of the PVC pipe straight joint 1 on a vertical axis is ensured to be within an allowable range, and the later-stage PVC pipe installation is ensured to be easy to connect, free of deviation, water-tight, reasonable in stress and guaranteed in quality. The fixing nail is connected in the fixing hole 3 through threads 4 and used for fixing the PVC pipe straight joint 1 (lower part) on the template at the lower part of the concrete floor 7 before the concrete floor 7 is not poured.
Before the concrete floor 7 is poured, after the formwork of the concrete floor 7 is erected, the position of the PVC pipe is located according to the axis, and the PVC pipe straight joint 1 is fixed on the formwork through the fixing nail 4. Will before steel reinforcement will pre-buried multi-functional PVC pipe stagnant water connects buried underground, buries PVC pipe straight joint 1 underground when underground, must pinpoint PVC pipe straight joint 1 position (adopt fixed orifices 3 and staple 4 location fixed) to guarantee to hang down straightness, the 1 axis deviation of PVC pipe straight joint must not be greater than 2mm on same root riser. When steel bars are bound, the PVC pipe straight joint 1 and the steel bar mesh are firmly bound, and the upper end interface 5 of the PVC pipe straight joint 1 is sealed by transparent adhesive tapes to prevent pollution and damage. The reinforcing mesh cannot be trampled when concrete is poured, so that the concrete protective layer of the reinforcing mesh meets the requirement and the reinforcing mesh does not move or deform; meanwhile, the PVC pipe straight joint 1 is ensured to be accurately and vertically positioned and the axis deviation meets the requirements. After concrete pouring is finished, the direct joint 1 of the PVC pipe must be protected in the subsequent construction process, and the direct joint cannot be stained or damaged. When the water pipe installation engineering is carried out, the plate penetrating installation work of the water pipe can be completed only by coating glue on the PVC pipe and connecting the PVC pipe in the PVC pipe straight joint 1.
It is to be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
