Technical Field

The invention relates to the technical field of pipeline supports, in particular to a W-shaped flexible cast iron drain pipe bearing structure.

Background

W type flexible cast iron drain pipe, bearing nozzle stub promptly is often used for the perforation department of floor, and it is mainly through clamp structure connection coexistence pipe tip, realizes the connection to two pipes to transmit the load of riser for the floor. The conventional means mainly adopts a structure that the floor slab of a clamp type bearing short pipe disclosed in the lower left corner of page 36 of 13S409 for mounting a flexible interface cast iron pipeline and a steel-plastic composite pipeline for drainage in building life is fixed, namely a connecting bracket is arranged between the cast iron drain pipe and the floor slab to realize load transmission.

But in practical engineering we find: according to the specification of 3.3.13 in 'construction quality acceptance standard for water supply and drainage and heating engineering GB 50242-2002': the pipeline passes through the wall and the floor, and a metal or plastic sleeve is arranged. The top of the sleeve pipe arranged in the floor slab is 20mm higher than the decorative ground; the top of the sleeve installed in the toilet and kitchen should be 50mm higher than the decorative ground, the bottom should be equal to the floor bottom, the top of the steel sleeve embedded between the floor perforation and the cast iron drainage pipe should be exposed about 20mm above the floor (i.e. the floor top), but the bracket is directly equal to the floor in the structure adopted by the conventional means, which is not suitable. Especially when the W type flexible cast iron drain pipe is external to B type flange, the flange bolt can be buried in the floor, and does not satisfy the standard requirement.

Therefore, there is a need for a new load-bearing structure for floor slab construction that does not prevent steel casing from being installed in the manner required by the above standards, and that ensures efficient load transfer of cast iron drainpipes to the building structure.

Disclosure of Invention

The invention aims to provide a W-shaped flexible cast iron drain pipe bearing structure which can prevent a component from contacting with a floor of a floor slab while ensuring that the load of a cast iron drain pipe can be effectively transmitted to a building structure.

The embodiment of the invention is realized by the following steps:

the utility model provides a flexible cast iron drain pipe load-bearing structure of W type, including:

the cast iron drain pipe is arranged right below the through hole of the floor slab; and the combination of (a) and (b),

Preferably, the number of the connecting beams is two, and the two connecting beams are symmetrically arranged along a vertical plane.

Preferably, the two connecting beams are connected to the same cross beam, or

The two connecting beams are respectively connected to the two vertical cross beams.

Preferably, the connecting portion is mainly composed of connecting lug seats which are formed on the periphery of the cast iron drain pipe and correspond to the connecting beam, and the connecting beam is fixedly connected with the connecting lug seats through a first bolt.

Preferably, the connecting beam mainly comprises a vertical part and a horizontal part, and the bottom end of the vertical part is fixedly connected with one end of the horizontal part, so that the connecting beam is in an L shape.

Preferably, the vertical part of the connecting beam is used for connecting with the cross beam, and the horizontal part of the connecting beam is used for connecting with the connecting part of the cast iron drain pipe.

Preferably, the connection beam is fixedly connected to the cross beam by a connection bolt having a connection end penetrating through the vertical portion and inserted into the cross beam.

Preferably, the connecting beam is fixedly connected with the cross beam through a plurality of connecting bolts, and the connecting bolts are sequentially arranged on the connecting beam along the vertical direction.

Preferably, the vertical part and the horizontal part of the connecting beam are both of a channel steel structure.

Due to the adoption of the technical scheme, the invention has the beneficial effects that:

(1) compared with the traditional mode, the W-shaped flexible cast iron drain pipe bearing structure provided by the invention has the advantages that the whole connecting beam is positioned below the floor, so that the contact between a member and the floor of the floor is avoided, the steel sleeve at the perforated position of the floor can meet the requirement that the sleeve specified in the acceptance criteria of construction quality of building water supply and drainage and heating engineering is exposed 20mm on the floor, and meanwhile, the pipeline load can be effectively transmitted to the cross beam, namely the floor structure.

(2) The W-shaped flexible cast iron drain pipe bearing structure provided by the invention can be correspondingly arranged according to the surplus degree of the space of a deployment site. In the middle of the higher environment of deployment site space surplus degree such as non-wall angle department, implementer can connect two tie-beams on same crossbeam, and in the middle of the environment that deployment site space is comparatively antagonism such as wall angle department, implementer can connect two tie-beams respectively on different crossbeams, and whole structure has the advantage that the suitability is strong.

(3) In the bearing structure of the W-shaped flexible cast iron drain pipe, the connecting beam is in an L-shaped shape with the horizontal part and the vertical part, and the horizontal part and the vertical part are both in a channel steel structure, so that the structural stability of the whole connecting beam is guaranteed, the processing difficulty of the connecting beam is reduced, and the connecting beam has feasibility of processing in a construction site.
