Description
Technical field
The utility model relates to a kind of construction tool for building, is specifically related to a kind of air-conditioning duct preformed hole and exempts from form removal tool.
Background technology
Building all needs to arrange many pipelines, be the intensity ensureing body of wall during construction, generally all adopt integrated poured method, for the ease of the pipe that installs an air-conditioner in the future, building side can when cast wall by placing the polybag of round log, plastic pipe or dress soil to form preserved pipeline hole, again with manually chiseling during installation, these methods not only waste time and energy, the problem of the dismounting of mould difficulty and burn failure is also there will be after shaping, and do not ensure the quality of preformed hole, the also destruction had is whole waters structure, affects the quality of floor.Also the building side had in addition is in order to clear-cut not preserved pipeline hole of saving trouble, etc. in actual air-conditioning installation process, need to carry out perforate by air-conditioner installation people to the body of wall after completion, the quality of perforate is uneven, also produce dust and rubbish simultaneously, the most important thing is the position due to wall steel bar cannot be judged during perforate, and the situation cutting off reinforcing bar occurs.In addition traditional preformed hole mostly is horizontal circular hole, very easily causes outdoor rain seepage directly to pour in down a chimney to indoor.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of hole quality good, do not need remove and the air-conditioning duct preformed hole that can prevent rainwater from pouring in down a chimney exempts from form removal tool.
In order to solve the problems of the technologies described above, the utility model provides a kind of air-conditioning duct preformed hole to exempt from form removal tool, comprise prefabricated steel concrete barrel shell, described steel concrete barrel shell comprises the reinforced concrete cylinder and two circular protrusions be oppositely arranged on that are obliquely installed, described circular protrusion be vertically arranged on reinforced concrete cylinder two ends and with the cast template inside wall phase apical grafting of body of wall, described steel concrete barrel shell is divided into two the grooved housings be symmetrical set, and grooved housing is bundled by rope and is fixed into entirety.
Adopt the air-conditioning duct preformed hole of technique scheme to exempt from form removal tool tool to have the following advantages: because barrel shell adopts reinforced concrete structure, and have employed prefabricate mode, therefore not only use cost is low, and intensity is compared and is become punch die also large with traditional; Reinforced concrete cylinder is obliquely installed can effectively avoid outside rainwater to flow into indoor; The cast template inside wall phase apical grafting of prefabricated steel concrete barrel shell two ends and body of wall, in the process of fluid concrete, position can not change like this, because material is consistent with materials for wall, after being used to complete and body of wall be integrated and directly form pre-manufactured hole, not only do not need to remove, and the quality of pore-forming is very good; Steel concrete barrel shell is divided into two the grooved housings be symmetrical set, and grooved housing is bundled by rope and is fixed into entirety, makes the processing mold of steel concrete barrel shell very simple like this.
Preferably, be provided with a waterproof coating in the inwall of described steel concrete barrel shell, such arranging can make steel concrete barrel shell being installed to better waterproof after on body of wall, avoids moisture to penetrate in body of wall.
Preferably, turn down outside the lateral, split position of described grooved housing, such arranging can make the split location contacts area of grooved housing larger, and not fragile.
Preferably; the circular hole at described reinforced concrete cylinder two ends has superposed surfaces in the horizontal direction; arranging like this can make to carry out more convenient when drawing fixing to the cast template of body of wall; because split bolt can directly directly pass from the hole of reinforced concrete cylinder, reinforced concrete cylinder protection split bolt does not directly contact with the concrete of cast.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model embodiment air-conditioning duct preformed hole exempts from form removal tool;
Fig. 2 is the end face structure schematic diagram that the utility model embodiment air-conditioning duct preformed hole exempts from form removal tool.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Reference numeral in Figure of description comprises, reinforced concrete cylinder 1, circular protrusion 2, cast template 3, rope 4, split bolt 5.
The utility model provides a kind of air-conditioning duct preformed hole to exempt from form removal tool as depicted in figs. 1 and 2, comprise the steel concrete barrel shell that batch production is prefabricated, steel concrete barrel shell comprises the reinforced concrete cylinder 1 and two circular protrusions be oppositely arranged on 2 that are obliquely installed, circular protrusion 2 vertical and be set in parallel in reinforced concrete cylinder 1 two ends and with the cast template 3 inside wall phase apical grafting of body of wall, in order to the convenience of processing, steel concrete barrel shell is divided into two the grooved housings be symmetrical set, preferably outwards turn down outside the split position of grooved housing, grooved housing is bundled by rope 4 and is fixed into an entirety, arranging of turnover can allow the split location contacts area of grooved housing larger, and it is not fragile, the inner wall surface of steel concrete barrel shell is coated with a waterproof coating, steel concrete barrel shell can be made like this to be installed to better waterproof after on body of wall, moisture is avoided to penetrate in body of wall, the circular hole at reinforced concrete cylinder 1 two ends has superposed surfaces in the horizontal direction, can make like this to carry out more convenient when drawing fixing to the cast template 3 of body of wall, now split bolt 5 can directly directly pass from the hole of reinforced concrete cylinder 1, reinforced concrete cylinder 1 protects split bolt 5 directly not contact with the concrete of cast.
It is work like this that the air-conditioning duct preformed hole of technique scheme exempts from form removal tool: barrel shell adopts prefabricate reinforced concrete structure, and use cost is low, and intensity is compared and become punch die also large with traditional; Reinforced concrete cylinder 1 is obliquely installed can effectively avoid outside rainwater to flow into indoor; The cast template 3 inside wall phase apical grafting of prefabricated steel concrete barrel shell two ends and body of wall, in the process of fluid concrete, position can not change like this, after being used to complete and body of wall be integrated as pre-manufactured hole, do not need dismounting, the quality of pore-forming is good; Last steel concrete barrel shell is divided into two the grooved housings be symmetrical set, grooved housing is fixed into entirety by rope 4 or other steel wire bundle and can uses, and is symmetrical set grooved housing and makes the processing of steel concrete barrel shell and the demoulding more convenient.
Above-described is only preferred embodiment of the present utility model; should be understood that for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
