CN2193900Y - Fire retardant and climb-preventing drainage pipe - Google Patents

Abstract

The utility model relates to a fire retardant and climb-preventing drainage pipe, which is used for the outer wall of buildings. The utility model is composed of a plurality of sections of pipe bodies (2) which are in sleeve joint with each other. The connecting point is provided with no step and is plane and smooth. Each section of the pipe bodies (2) has the structure that the upper and lower parts are respectively provided with fixing lugs (1) which are integrally connected with the upper and lower parts. An inner subsiding socket (3) is arranged on the upper end. Each section of the pipe bodies (2) has the shape that the back surface (surface pasted to the wall) is a flat bottom surface. The side face (the portion extrudes from the wall surface) forms an arcs shape. The utility model has the advantages of climb-preventing, fire retardant, light weight, material saving, convenient production and transportation, safety, etc. The utility model belongs to the new-generation product which can replace the existing drainage pipe.

Description

Fire retardant and climb-preventing drainage pipe

The utility model is that fire-retardant leader is climbed in a kind of resistance of used for building exterior wall.

At present, depending on the leader of the discharging rainwater on civilian and the industrial construction exterior wall, generally all is that cast iron is made, and the cross section of this pipe fitting is circular, and point of attachment has the thick step of 10mm approximately.The problem that this structure is brought mainly is to help human body to depend on upwards climbing of tube wall, condition easily objectively is provided necessarily for pivot frame burglary person, brings great harm to social public security.In addition, leader could be installed after all will burying the iron fastener underground in the civil engineering stage, therefore give to install and also make troubles.

The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, easy for installation and help safeguarding that the resistance of social public security climbs fire-retardant leader.

The purpose of this utility model is achieved in that the structure of every pipe joint body is, its upper and lower part respectively is provided with the fixedly ear that is connected as a single entity with it, its upper end is provided with for its pipe joint body lower end inserts the interior heavy socket that connects, thereby it is sliding to make 2-section pipe body junction not have step peace lay the grain; Its back side (being wall covering surface) is flat bottom surface, and side (being the protruding wall face portion) is arc shape.

Above-mentioned arc shape side, its cross section can be semicircle or the circle of contact (promptly less than semicircle) or half-oval shaped, and this kind shape makes body have resistance and climbs effect.

Above-mentioned body can adopt cast iron with fire resistance or plastics or glass-reinforced plastic material to make.

The utility model has following advantage than prior art:

The one, resistance is climbed, and helps safeguarding social public security, and this is because the junction of adjacent body does not have the sliding cause of step peace lay the grain;

The 2nd, be unfavorable for that stealer depends on that tube wall is upwards climbed and in light weight, economize material and cost descends, this is because the result that the body cross sectional shape is changed into semicircle or brought later on less than the circle of contact or the semiellipse of semicircle by circle;

The 3rd, to be convenient to produce and to install, this is because save and have step and must the pre-buried connecting piece that could install, and has adopted the cause of the fixedly ear that is connected as a single entity with body;

The 4th, after The selection of pipe plastics or the glass fiber reinforced plastic, not only weight lightens and can save the brushing paint operation, and is convenient to transportation and installation, and outward appearance is also beautiful.

In addition, because plastics or the glass fiber reinforced plastic making body selecting cast iron for use or have fire resistance, so help eliminating safety.

In a word, the utility model is a kind of product that can substitute the update of existing leader.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 be among Fig. 1 A to schematic diagram;

Fig. 3 is a B-B sectional view among Fig. 1.

As shown in Figure 1 and Figure 2: in every pipe joint body 2, its upper and lower part respectively is provided with the fixedly ear 1 that is connected as a single entity with it, heavy socket 3 in its upper end then is provided with, and its back side (being wall covering surface) is flat bottom surface, side (being the protruding wall face portion) then is arc shape.The cross section of this arc shape side is a semicircle (seeing Fig. 2, Fig. 3) or less than the circle of contact or the half elliptic of semicircle.

The utility model can be cylinder iron or plastics or glass-reinforced plastic material with fire resistance make.

During installation, plane with first segment body 2 is affixed on metope earlier, this moment fixedly ear 1 be affixed on the metope, again with nailing fixedly ear 1 be securely fixed on the metope, so, this pipe joint body is fixedly mounted on the metope, then, the lower end of the second pipe joint body 2 interior heavy socket 3 along first segment body 2 is inserted, behind the position that falls, this moment, junction was upper and lower as integral body, smooth smooth; Make fixedly ear 1 fixing on the wall with nailing again, so the second pipe joint body also is firmly mounted on the wall.Repeat above action, till final section body 2 installs.

Claims (4)

1, fire-retardant leader is climbed in a kind of resistance of used for building exterior wall, it is characterized in that described leader, be to interlock by some pipe joint bodies (2) to form, junction does not have step, smooth smooth, the structure of every pipe joint body (2) is that its upper and lower part respectively is provided with the fixedly ear (1) that is connected as a single entity with it, heavy socket (3) in the upper end then is provided with, the back side of this body (being wall covering surface) is flat bottom surface, and side (being the protruding wall face portion) then is arc shape.

2, leader according to claim 1 is characterized in that described leader, and the cross section of its arcuate flanks is semicircle or circle of contact shape or half elliptic.
