Abstract

The invention discloses a making method for pre-reserved holes of pipes in buildings, which is characterized in that the holes of the pipes are pre-reserved step by step: firstly, a fine sleeve is fixed on a template by a fixing rod avoiding positions for the pre-reserved holes; a main reinforced rib and a structural rib at the position of each pre-served hole are bonded; after bonding, a coarse sleeve is covered on the fine sleeve and then arranged on the bonded main reinforced rid and the structural rib, and then the structural rib and a latch is bonded and bent at positions of outer sleeves during bonding; 3. after the main reinforced rib, the structural rib, the coarse and the fine sleeves are made sure not to be displaced, the concrete is cast; 4. the coarse and the fine sleeves as well as templates are stripped from the cast concrete, and the pre-reserved holes are finished. Pre-reserved holes made with the invention have small hole diameter, high intensity of the pre-served hole positions of the pipes; during installation of pipes, the cast concrete is not necessary to be dug so as not to damage the stressed reinforced ribs, which improves the engineering quality; mould stripping is easy, so that the moulds are reusable, which reduces the construction cost and obviously improves the working efficiency.

Description

The preparation method of architecture pipeline preformed hole

One, technical field:

The present invention relates to a kind of preparation method of architecture pipeline preformed hole.

Two, background technology:

Building all needs to be provided with many pipelines, as above sewer pipe, natural gas line, air-conditioning duct etc.In the building storey pipeline preformed hole, there are two big technologies complicated at present, have much room for improvement.One, preformed hole mould: when concreting, need on floor, to reserve an eyelet bigger than caliber, pass for pipeline, present way mainly adopts thick batten, follow closely into the square tub by caliber, on template, throw off with template the cast back as the mould nail, just form cubic hole, the existing mold way, more original, take a lot of work, take material, an eyelet needs a model, wastes a large amount of timber.And generally be to lay main reinforcement and distributing bar earlier, installation mold if laying main reinforcement and distributing bar influence the installation of mould, must be done bending process with reinforcing bar again, influences the intensity of main reinforcement like this, makes preformed hole position intensity low.They are two years old, lay template in the floor bottom: pipeline passes from reserving eyelet during installation, because pipeline and preformed hole have the gap of very big adjusting deviation, need play cutter cast-in-situ concrete during piping erection, destroy steel bar stress, need during sealing of hole lay template once more in the preformed hole bottom, template is fixing adopt pin top, bottom or with iron wire around above floor, hanging, fluid concrete again, this kind method, not only time-consumingly take material, and template often occurs and cave in, often do over again.

Three, summary of the invention:

The present invention solves now with the problems referred to above that exist in the technology, a kind of preparation method of architecture pipeline preformed hole is provided, the mould that this method is used can use repeatedly, secondary hole sealing need not re-lay template, do not destroy the structure of main reinforcement, main reinforcement significantly improves operating efficiency at the position of preformed hole intensity height.

For addressing the above problem, technical solution of the present invention is: a kind of preparation method of architecture pipeline preformed hole, the steps include: 1, unwrapping wire, and accurately mark the position of preformed hole; 2, the substep of pipeline preformed hole is reserved: the mould of use is made up of thick, thin two sleeve pipes and threaded fixed bar, the first step is fixed on thin sleeve pipe on the template by fixed bar, avoid the preformed hole position, colligation preformed hole position main reinforcement and constructional reinforcement, after colligation is finished, second step with thick casing pipe sleeve on thin sleeve pipe, place on the main reinforcement and constructional reinforcement of colligation colligation constructional reinforcement and button iron again, run into the position of outer tube during colligation, constructional reinforcement is done bending process; 3, guaranteeing fluid concrete under the situation that main reinforcement, constructional reinforcement and thick, thin sleeve pipe are not subjected to displacement; 4, thick, thin sleeve pipe and mould are pulled the concrete of cast, preformed hole is promptly finished.

Foregoing invention is wooden form or bamboo plywood form as the template of using, and can directly fixed bar be screwed on the template, as be steel form, can punch and tighten with the nut shimming.

The present invention installed by two steps of strict unwrapping wire and thick, thin two sleeve pipes, made the reservation aperture little at the paving location of main reinforcement, and main reinforcement need not to do bending process when laying, and has guaranteed main reinforcement intensity, has guaranteed the intensity at pipeline preformed hole place.Dwindled the diameter of a part below the preformed hole, not only do not influenced the installation of pipeline, and secondary hole sealing need not re-lay template, reduce the operation of piping erection, reduce working strength of workers.Need not play cutter cast-in-situ concrete during piping erection, destroy steel bar stress, improve workmanship, after the piping erection, with miniature expansive concrete plug-hole, the pipe root be carried out waterproofing work, the probability that infiltration takes place is minimum.In a word, the preformed hole that adopts the present invention to make, its aperture is little, the intensity height at pipeline preformed hole place, need not play cutter cast-in-situ concrete during piping erection, destroy steel bar stress, improved workmanship, the probability that infiltration takes place behind the sealing of hole is minimum, the demoulding is easy, its mould can use repeatedly, has reduced construction cost, significantly improves operating efficiency.

Four, description of drawings

Below in conjunction with accompanying drawing the present invention is further described:

The front view that the mould that Fig. 1 uses for the present invention is installed together;

The vertical view that the mould that Fig. 2 uses for the present invention is installed together;

Fig. 3 for colligation behind the first step preformed hole of the present invention vertical view behind main reinforcement and the constructional reinforcement;

Fig. 4 for the present invention second step preformed hole after colligation the vertical view of constructional reinforcement.

Five, the specific embodiment:

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the preparation method of a kind of architecture pipeline preformed hole of the present invention the steps include: 1, unwrapping wire, accurately marks the position of preformed hole.2, the substep of pipeline preformed hole is reserved: the mould of use is by slightly, thin two

sleeve pipes

3,2 and threaded fixed bar 1 form, template is a wooden form, the first step is screwed in thin sleeve pipe 2 on the wooden form by fixed bar 1, avoid preformed hole position 2-3mm, colligation preformed hole position main reinforcement 5 and constructional reinforcement 6, spacing between the main reinforcement 5 is no more than 10mm, after colligation is finished, second step was enclosed within thick sleeve pipe 3 on the thin sleeve pipe 2, place on the main reinforcement 5 and constructional reinforcement 6 of colligation, colligation constructional reinforcement 6 and button iron again, run into the position of outer tube 3 during colligation, constructional reinforcement 6 is done bending process.3, guaranteeing fluid concrete under the situation that main reinforcement 5, constructional reinforcement 6 and thick,

thin sleeve pipe

3,2 are not subjected to displacement.4, thick,

thin sleeve pipe

3,2 and wooden model are pulled the concrete of cast, preformed hole is promptly finished.5, after the piping erection,, the pipe root is carried out waterproofing work with miniature expansive concrete plug-hole.4 is body of wall.
