Abstract

The utility model discloses an extensible fixable waterproof casing pipe, which comprises a rigid inner pipe and a rigid outer pipe which are matched in pipe diameters. Corresponding threaded screws capable of being mutually screwed are embedded on the outer side of one end of the inner pipe and the inner side of one end of the outer pipe, and a fixed plate is positioned at the other end of the outer pipe. Due to the different screwed positions of the inner pipe and the outer pipe, the length of the waterproof cased pipe can be lengthened or shortened to meet requirements of different thicknesses of concrete structure members. By means of the fixing plate, the extensible fixable waterproof casing pipe can be fixed on a concrete template, thereby enabling the pre-embedded position of the waterproof casing pipe to be accurate.

Description

Scalable fixedly water string

Technical field

The utility model relates to a kind of water string, especially a kind of scalable and fixing water string.

Background technique

Basement, tunnel, preserving solution pond and concrete structure engineerings such as industry and civil building in civil construction project; Need wear a large amount of technologies and water supply and sewerage pipeline; For preventing pipeline and concrete surface percolating water, need reserve and a kind ofly prevent that the sleeve pipe of percolating water from being water string passing pipeline coagulation Tu Chu.At present; A large amount of water strings scene that is produced on is taken steel pipe temporarily and is cut out; The circular steel loop of welding sealing uses reinforcing bar not have technical stipulation and welds fixedly water string, because the field fabrication processing conditions is poor; Personal factor influences the welded seam quality and does not reach standard-required, and causes the water string percolating water phenomenon.Idol has water string to complete in advance, because various construction element sizes are different, the length of water string does not match, and is difficult to fix during construction, influences the pre-buried rational position of sleeve pipe and causes and cut sleeve pipe and construct again, brings economic loss to engineering.

Summary of the invention

The purpose of the utility model is to provide a kind of scalable fixedly water string; This water string can extend and shorten as required; Satisfy the different size dimensions of concrete works construction element, and sleeve pipe is fixed on the concrete works template, avoid pre-buried position unreasonable through screw.

The technological scheme that the utility model passes through is: a kind of scalable fixedly water string; The interior pipe of rigidity, the outer tube that comprise the caliber coupling; It is characterized in that; Said, outer tube one end is inboard to be inlaid with corresponding internal thread silk and the external thread wire that can tighten each other respectively with the outside, interior pipe one end, in the outside, the other end of outer tube the fixed plate that radially extends out along sleeve pipe is housed.

Preferably, on the said fixed plate Drilling screw.

Preferably, pipe and outer tube pipe range was half the in said internal thread silk and external thread wire length were respectively.

The advantage of the utility model is: 1) different extending or shorten the different-thickness that water string length satisfies concrete structure member through inner and outer pipes being tightened the position.2) be fixed on the concrete shuttering panel through fixed plate, thereby make the pre-buried position of water string accurate.3) can be for convenience detach through screw.4) water string can complete in factory in advance, guarantees that the weldquality of steel plate for sealing water and water string welding meets standard-required, and saves on-site construction time.

Description of drawings

Fig. 1 is the scalable fixedly water string of a utility model generalized section;

The scalable fixedly water string of Fig. 2 the utility model perspective view.

Embodiment

A kind of scalable fixedly water string; The practical implementation process is following: the interior pipe 1 and outer tube 2 that use rigidity; In pipe 1 identical with the internal diameter of managing 1 external diameter and outer tube 2 in the caliber of outer tube 2 is complementary promptly; Outer tube one end is inboard to be inlaid with the corresponding internal and external screw thread silk 3 that can tighten each other respectively with the outside, interior pipe one end, and inner and outer pipe screw thread filament length degree is respectively interior pipe, the outer tube pipe range is half the, twists synthetic one group of water string each other through inner and outer pipe wire connection position; Press the different can regulate water string of inner and outer pipes wire connection length of action length, satisfy the different-thickness of on-site concrete construction element.Steel plate for sealing water 6 at interior pipe 1 middle part outer wall continuous welding water string.

In the outside, outer tube the other end the fixed plate 4 that radially extends out along sleeve pipe is housed, even 3 screws 5 of Drilling are fixed on water string on the concrete shuttering panel with corresponding big Screw on fixed plate 4.

Above content is the further explain that the utility model is done; The practical implementation that can not assert the utility model is confined to these; Those of ordinary skill for technical field under the utility model; Make some being equal under the prerequisite of the utility model design and substitute or obvious modification not breaking away from, and performance or purposes are identical, then should be regarded as belonging to the scope that the utility model is protected.

Claims

1. scalable fixedly water string; The interior pipe of rigidity, the outer tube that mainly comprise the caliber coupling; It is characterized in that; Said outer tube one end is inboard to be inlaid with corresponding internal thread silk and the external thread wire that can tighten each other respectively with the outside, interior pipe one end, in the outside, the other end of outer tube the fixed plate that radially extends out along sleeve pipe is housed.

2. according to the said a kind of scalable fixedly water string of claim 1, it is characterized in that, on the said fixed plate Drilling screw.

3. according to the said a kind of scalable fixedly water string of claim 1, it is characterized in that pipe and outer tube pipe range was half the in said internal thread silk and external thread wire length were respectively.
