Abstract

The present invention discloses a leakage preventing construction method and equipment for gaps between floorslabs and pipelines, which can be widely used in the installation construction of story penetrating drainage pipelines in toilets, scouring chambers and kitchens in various houses with multiple layers and communal buildings. The present invention is characterized in that prefabricated parts are positioned by a positioning rule; pea gravel concrete slurry is poured into gaps between pipelines and the prefabricated parts firstly, and waterproof ointment is poured into the gaps then. The present invention ensures the qualification of one time operation and has no leakage. The construction method is convenient and easy, and matching parts and specific tools can be manufactured easily and can be used by every building construction unit.

Description

A kind of floor and pipeline gap anti-seepage construction method and equipment

The invention belongs to building construction technology, particularly floor and pipeline gap anti-seepage construction technology and equipment.

Pipeline is all installed down in the dwelling house of multilayer and the washroom of public building, the chamber of scrubbing, and sewer pipe and floor junction are easy to occur seepage usually, and the resident of lower floor usually is subjected to the hardship of dripping of last layer seepage.Bury with wooden unit at preparation place, tubulature road when job practices commonly used at present is the pouring floor, just cut off as tensile reinforcement.During pipe laying such as reserved opening not canonical chisel reaming up and down, irritate with concrete grout at floor and pipeline gap the fixing back of pipeline, produce seepage because of easily producing micro gap between concrete and cast-iron pipe, simultaneously because of cutting off the intensity effect construction quality that the part reinforcing bar reduces floor.

The purpose of this invention is to provide a kind of hot-water heating pipe fitting and floor ground joint portion once construct qualified non-leakage job practices and supporting with it accessory and instrument of guaranteeing.

The present invention realizes by following manner, propped up after template ties up reinforcing bar on a last floor ground, reserving the pre-square-outside and round-inside of placing in pipe hole place, and circular hole is greater than the precast unit of outer diameter tube 4-5cm, positioning rule on the card in component hole, by the positioning rule centre bore vertical that hangs down, mobile precast unit utilizes vertical that itself and the precast unit center of following one deck with pipe hole are aligned, the levelling level, after the correction precast unit exposed steel bar and floor ground are tied up the system reinforcing bar and weld, placing of concrete is made floor ground then.During pipe laying cast-iron pipe passed the precast unit circular hole, be connected with levels, press close to snake joint holder on the holder floor face card, pour into a mould the pea gravel concreten of about 1/2nd thickness to pipeline and precast unit slit, the next day water full slit with waterproofing unction again, remove the holder of snake joint after the initial set.

Positioning rule is for to make the mutually perpendicular Cross ruler of axis with same material, the scale of ruler is that initial point is to cubic graduation with the axes intersect point, on orthogonal chi face, a spirit level is installed respectively, with the initial point center circular centre hole of making a call to a 10-15mm, the aperture of on each chi face, beating the installing and locating jump ring every 10mm, jump ring be two apertures that 10mm at interval arranged with arc curved its horizontal ends of spring leaf for the fixing usefulness of positioning rule, also can on each chi, connect chi with increase chi face length degree as required with screw.

The annulus that snake joint holder is combined into for polylith arc wooden unit has the countersunk that installs and fixes bolt on the circular diameter direction of wooden unit, internal radius is identical with institute tubulature road external diameter, and cylindrical is with an adjustable circular boop and a bolt.

Member and special tool that job practices provided by the invention has easy to use, easy construction, employing are easy to make, simple to operate, the construction precision height, because good weatherability can both be combined closely and have to waterproofing unction and pipeline and concrete, guarantee that seepage does not appear in pipeline and floor gap so have once construction with the pipeline of this process Installation, avoided simultaneously because of staying pipe hole to cut off the problem that reinforcing bar influences floor strength, thereby improved the washroom, the construction quality in drainage pipe room is arranged between scrubbing etc.

Further the present invention is set forth below in conjunction with accompanying drawing.

Fig. 1 is the construction generalized section.

Fig. 2 is the positioning rule structural representation.

Fig. 3 is the jump ring structural representation.

Fig. 4 is for connecing the chi structure chart.

Fig. 5 is snake joint holder structure schematic diagram.

Fig. 6 asks A-A to sectional view for the snake joint.

As shown in Figure 1, before pouring floor 1, concrete component 2 is fixed in and pacifies pipeline location with positioning rule, welded the snake joint holder 6 on the underfloor card of reinforcement installation pipeline 4 backs, the pea gravel concreten of about 1/2nd thickness of cast starches 5 earlier in the precast unit hole, and the next day fills with waterproofing unction again.

As Fig. 2, Fig. 3, shown in Figure 4, positioning rule is for to make the mutually perpendicular

Cross ruler

7,11 of axis with same material, the scale of ruler is that initial point is to cubic graduation with the axes intersect point, with the initial point is that the center is made a call to a centre bore 9, a spirit level 8,12 respectively is installed on the chi face, on each chi face, be equipped with the fixedly equidistant aperture 10 of jump ring 13, all but attaching chi 14 is to increase length for ruler, and jump ring is an arcuate bombing leaf, and its horizontal ends is equipped with the aperture identical with the chi interplanar distance.

As Fig. 5, shown in Figure 6, the annulus that the holder of snake joint is combined into for polylith arc wooden unit 15 has the countersunk that installs and fixes bolt 16 on the wooden unit circular diameter direction, and its cylindrical is fixing with adjustable circular boop 18 and bolt 17.
