Abstract
An inner fixing connector, not penetrating through a beam bottom template, of a pre-buried line pipe comprises a sleeve vertically arranged on the beam bottom template. A locating block is arranged in the sleeve. A gap in which the pre-buried line pipe can be inserted is reserved between the locating block and the inner wall of the sleeve. A screw is inserted downward in the center of the locating block. The lower portion of the screw penetrates through the locating block and is fixed with the beam bottom template. At the construction time of the inner fixing connector, the inner fixing connector is fixed on the beam bottom template through the screw after water and electricity facility positioning is completed, the line pipe is directly in butt joint with the connector at secondary pipe distributing time, and the line pipe connector is cleaned, and steel nails and the locating block are pulled out after concrete casting is completed and a die is detached. The inner fixing connector eradicates a series of common quality defects caused by mechanical trepanning on the beam bottom template, reduces the conflict of mechanical and electrical installation and civil engineering cross-operation, enables mechanical and electrical installation cost and civil engineering cross-operation cost to be well controlled, and embodies good economic benefits.
Description
Technical field
The utility model relates to a kind of spool Embedment Construction line pipe joint used.
Background technology
The pre-buried technique of spool is used very extensive, great in constructing amount in ordinary reinforced concrete structure construction.The pre-buried technique of traditional water power, wears the mode that spool at the bottom of beam all adopts electric drill perforate location in template, in the direct patchhole of spool.The mode of this mechanical tapping causes template to be destroyed, reduction template life cycle; Perforate process especially produces a large amount of sawdusts, wood chip at the bottom of beam in template, is difficult to clean out, and easily produces the mass defects such as honeycomb, pitted skin, crust after concrete formation.If dislocation, discarded pore place carry out shutoff not in time in casting process, can produce spillage phenomenon, have a strong impact on the impression quality of this position concrete formation, and cause terrace to pollute, be difficult to clear up.
Along with society is more and more higher to the requirement of construction engineering quality, how rationally to effectively reduce construction cost, improve the market competitiveness of enterprise in charge of construction, be that each construction enterprises all needs the matter of utmost importance of considering.The perforate of beam bottom mother plate spool becomes the technology " bottleneck " of cost control and quality raising gradually, and a kind of new technique of site operation exigence, solves pre-embedded pipe and wear the above-mentioned common quality defect that template causes.
Utility model content
The utility model provides a kind of pre-embedded pipe not wear the interior anchor tip of beam bottom mother plate, solving existing spool Embedment Construction mode easily causes template to be destroyed, affect concrete formation quality, construction rubbish is difficult to cleaning, and the technical problem of plate hole place spillage while watering concrete.
The utility model solves the technical scheme that its technical problem adopts:
This pre-embedded pipe is not worn the interior anchor tip of beam bottom mother plate, comprise the sleeve pipe being vertical on beam bottom mother plate, sleeve pipe is built-in with locating piece, between locating piece and internal surface of sleeve pipe, leave the gap that can insert pre-embedded pipe, locating piece center is inserted with screw downwards, and screw bottom passes locating piece and fixes with fine strain of millet soffit formwork.
Between described locating piece end face and screw, be provided with catch, catch and locating piece end face are measure-alike, and catch center is provided with bolt hole.
The material of described locating piece is rigid foam.
The length of described sleeve pipe and the caliber of pre-embedded pipe adapt.
The beneficial effects of the utility model are as follows:
Interior anchor tip of the present utility model is when construction, after water power has been located, it is fixed on beam bottom mother plate by screw, during secondary pipe arrangement, spool is directly docked with joint, concreting completes also, after form removal, line pipe joint place is cleared up and pull out steel nail and locating piece.The locating piece of catch in can fixed sleeving, while being convenient to form removable, nail is pulled out together with locating piece.
The utility model is having following advantage aspect raising construction quality:
1, the utility model when construction pre-embedded pipe do not wear beam bottom mother plate, thereby can stop a series of construction common faults that beam bottom mother plate punching causes, make pre-embedded pipe beam at the bottom of joint concrete structure quality qualification rate reach 95%.At the bottom of the form removal back rest, not residual ailhead, can save cost of labor, does not damage template, on structural strength without impact.
2, the interior anchor tip of field by using is all concentrated processing at construction camp, improved working (machining) efficiency, the joint uniform specification of made, steady quality, reduce the generation of the problems such as line pipe joint easily gets loose, scrappage height, and avoided producing at the scene processing garbage waste, embodied the advantage of " batch production production ".
3, the construction rubbish producing in spool installation process is less, especially can at the bottom of beam, not produce sawdust, has stopped to produce the possibility of mass defects such as " honeycomb, pitted skins " because template perforate causes concrete formation rear surface.
4, because line pipe joint is not clear, expose outside, can not produce above-mentioned intersection and destroy problem, thereby save manually, reduced structural deterioration, increased economic benefit.
5, avoid template dislocation, distortion that perforate vibrations cause, connected the problems such as loosening, thereby reduced to a certain extent the probability of the mould that rises in concreting process, burst-mode, improved the planeness of concrete beam moulding.
6, stopped because of template perforate cause water concrete time pore spillage.During form removal, because being adhered " crust " problem causing, pore place concrete grout and template be also fundamentally resolved.
The utility model has following advantage aspect increasing economic efficiency:
1, save material, owing to not boring a hole on beam bottom mother plate, can template not produced and be destroyed, greatly increased the number of turnover of beam bottom mother plate, reduced template loss.
2, save manually
A) owing to not needing to carry out mechanical punching at the bottom of beam, every layer of top board can be saved 1 working day positioning time;
B) after civil engineering form removal, do not need to carry out beam bottom line tube head saw short, save 1 working day for every layer;
C) join the processing of mould, template and reduce by 0.5 working day for average every layer;
D) processing line union, every layer increases by 0.2 working day.
Take typical floor as example, adopt after the utility model, on every layer of direct saving artificial 2.3 working day, reduced dynamo-electric installation and civil engineering cost of labor; Owing to adopting spool not wear template new technology, beam bottom mother plate, because of the loss minimizing 100% that the pre-buried perforation of spool causes, can be saved a large amount of templates and template processing cost.
A series of common quality defects that beam bottom mother plate mechanical tapping causes have been stopped in enforcement of the present utility model, have reduced the contradiction of dynamo-electric installation and civil engineering cross-operation, make dynamo-electric installation cost and civil engineering cost all obtain good control, have embodied good economic benefit.
