Abstract

The utility model discloses a hard plastic composite 90 DEG oblique three-way pipe used for building water drainage. The utility model comprises a section of vertical pipe, wherein, the upper end of the vertical pipe is connected with an upper bearing opening and the lower end is an inserting opening. One side of the vertical pipe is connected with an oblique pipe which forms an intersection angle of 45 DEG with the vertical pipe, the upper part of the oblique pipe is provided with a side bearing opening which is connected with a bending head with an angle of 43 DEG 34'-44 DEG 25', and the outer end of the bending head is provided with a bearing opening. The hard plastic composite 90 DEG oblique three-way pipe conforms to the requirements of the quality acceptance specification of building water feeding, water draining and heating engineering construction of 2002 year. The included angle of the vertical pipe and a transverse pipe is 88 DEG 34'-89 DEG 25' which approaches 90 DEG, and the included angle of each three-way pipe is determined by the nominal diameter of the three-way pipe. The utility model is used without any other pipe fittings, the upper bearing opening of the hard plastic composite 90 DEG oblique three-way pipe is connected with a water draining pipe or an air ventilating pipe of an upper floor, the bearing opening of the bending head is connected with a water draining transverse pipe, the angle of the bending head conforms to the gradient requirement of a new standard, and the lower inserting opening of the utility model is connected with an expansion joint. The utility model has the advantages of convenient installation, time saving, labor saving and material saving. Because of fewer interfaces, engineering quality is enhanced, and maintenance workload is reduced.

Description

The used in construction drainage Hard plastic composite 90 degree bevel arm piece

Technical field the utility model relates to a kind of threeway of used in construction drainage, is that a kind of used in construction drainage is moulded 0 ° of skew T of compound 69 firmly specifically.

Background technology is GB50242-2002 according to new " building plumbing system and heating engineering construction quality standards of acceptance ", the horizontal pipe that is used for indoor drainage, with should adopt 45 ° of threeways and 90 ° of skew Ts being connected of VERTICAL TUBE, there are not 90 degree skew Ts at present in the draining hard plastic tube spare of GB/5836.2-92, as needing on its oblique bellmouth, to connect one eighth bend with 45 ° of degree skew Ts, 45 the following of degree skew Ts can not directly connect expansion coupling for bellmouth, need to descend bellmouth to connect one section pipe again, but transverse tube was a level after above-mentioned two pipe fittings connected, be difficult to meet the requirement of new criteria conduit slope again, the constructor makes transverse tube form a kind of gradient of rule inadequately by every means, make pipe fitting impaired when firmly facilitating the gradient more easily, or bonding mouthful of seepage, influence workmanship, increase maintenance load, also bring a lot of troubles to the user.

The summary of the invention the purpose of this utility model is to provide a kind of used in construction drainage to mould 0 ° of skew T of compound 69 firmly, use it to connect vertical drain and transverse tube, need not connect other pipe fitting again, and the transverse tube that is connected meets the slope requirement of above-mentioned new criteria, also meet the requirement that connects expansion coupling under the construction drainage code requirement vertical tube, the time and labour saving material-saving, installation quality is reliable.

The technical solution of the utility model is as follows:

This compound threeway one section vertical tube arranged, the upper end connects bellmouth, the lower end is a socket, it is 45 ° inclined tube that a side is connected with the vertical tube angle, the top of this pipe is the side bellmouth, the side bellmouth connect an angle be 43 ° 34 '～44 ° 25 ' elbow, the outer end of elbow is a bellmouth.

Advantage of the present utility model is: 1, to meet " building plumbing system and heating engineering construction quality standards of acceptance " be the requirement of GB50242-2002 in this threeway, the angle of its vertical tube and transverse tube be 88 ° 34 '-89 ° 25 ', nearly 90 degree, the angle of each threeway is determined according to its nominal diameter.2, use this threeway, need not connect other pipe fitting again, bellmouth connects the gutter or the permeability cell of first floor on it, the bellmouth of the elbow water transverse tube that runs in, the angle of elbow meets the slope requirement of new criteria, its down socket connect expansion coupling, time and labour saving easy for installation material-saving.2, because of interface is few, improve workmanship, reduce maintenance load.

Description of drawings Fig. 1 is existing 45 degree skew T structure charts;

Fig. 2 is the utility model sectional structure chart.

The utility model is described in further detail can see the structure chart of 45 degree skew Ts of usefulness till now by Fig. 1 below in conjunction with accompanying drawing for the specific embodiment, it is that the standard in 92 years is GB/T5836.2-92, connecing transverse tube now connects an one eighth bend again and then connects transverse tube on its side bellmouth (1) exactly, transverse tube is a level, need artificial Wei certain angle, because of its lower end is bellmouth (2), just can connect the expansion coupling that the construction drainage code requirement connects after connecing one section pipe again.

Can see structure of the present utility model by Fig. 2, this threeway one section vertical tube (3) arranged, the upper end connects bellmouth (4), the lower end is socket (5), one side connect one with the vertical tube angle be 45 ° inclined tube (6), the top of this pipe is side bellmouth (7), the side bellmouth connect an angle be 43 ° 34 ' elbow (8), the outer end of elbow is bellmouth (9).

Just elbow is bonded on the side bellmouth in producer during production.

The gradient of dewatering horizontal tube is decided with caliber, and the transverse tube caliber is more little, and the gradient of its aspect vertical tube is big more.The angle of this threeway for the α angle add 45 the degree promptly 88 ° 34 '-89 ° 25 ' between; Each section of the different pipes of its nominal diameter has corresponding length.
