Description
Technical field
The utility model relates to a kind of mould that is used to build, and particularly relates to a kind of installing engineering reserved holes of pipes mouth assembling die that is used for.
Background technology
Traditional floor riser tube hole is reserved, and two kinds of methods are generally arranged, first kind of mould for adopting the bamboo and wood template to nail.Advantage is that an expense is cheap, and shortcoming is that most the use once promptly scrapped and contaminated environment; Another kind of UPVC pipe advantage is made simple with UPVC pipe or steel pipe reservation, and shortcoming is that general use is once promptly scrapped; The steel pipe advantage is to make simply, can repeatedly use, but cost is too high.In addition, more than several moulds two fatal shortcomings are all arranged: the one owing to do not do trapezium structure, stifled hole difficulty ftractures easily after a period of time and comes off, and stays infiltration and potential safety hazard; The 2nd, to remove inconveniently, concrete is difficult to remove after reaching intensity, and concrete does not reach intensity and removes by force and can influence the concrete structure.Up to the present, also not seeing the good substitute products of performance occurs.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of be convenient to stifled hole, convenient remove be used for installing engineering reserved holes of pipes mouth assembling die.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of installing engineering reserved holes of pipes mouth assembling die that is used for, comprise template and fastening devices thereof, described template is the separate trapezoidal steel plate of polylith, form the back taper stage body of going up lower open mouth after all trapezoidal steel plate amalgamations, survey in the described trapezoidal steel plate and be welded with the interior fixed block that is provided with endoporus, the outside is welded with the external fixation piece that is provided with endoporus up and down; Described fastening devices comprises the longitudinal reinforcement that is inserted in the interior fixed block endoporus, the upper end of described longitudinal reinforcement is welded with horizontal reinforcement, described longitudinal reinforcement is corresponding with the vertebra angle of described cone table with the angle of horizontal reinforcement, the cardinal principle centre position right-angled intersection of described longitudinal reinforcement is welded with transverse reinforcement, all horizontal reinforcement welding.
Described trapezoidal steel plate is a checkered steel plate.
Fixed block is positioned at the lateral mid-point of trapezoidal steel plate substantially in described.
The height of fixed block is 1/2～3/4 of a whole trapezoidal steel plate in described.
Described back taper stage body is positive rectangular pyramid stage body.
Described horizontal reinforcement right-angled intersection welding.
Fixed block is a nut in described.
Described external fixation piece is a nut.
Advantage and the good effect that the utlity model has are: by fixedly reinforcing bar aggregate erection, after removing fixedly reinforcing bar, every face die plate is independent existence, therefore after concrete reaches intensity fully, can remove easily, and easy to carry, but simple, easy to use, cheap, safe and reliable, pollution-free independent assortment made, can repeatedly repeat turnover, be particularly suitable for the pipeline riser reserving hole.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view.
Among the figure: 1, checkered steel plate, 2, horizontal reinforcement, 3,5, nut, 4, transverse reinforcement, 6, longitudinal reinforcement.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of installing engineering reserved holes of pipes mouth assembling die that is used for, comprise the 1. thick step pattern steel plate 1 of four sides 3mm, form the positive rectangular pyramid stage body of going up lower open mouth after all trapezoidal steel plate 1 amalgamations, the benefit that adopts trapezium structure and checkered steel plate is to increase friction factor, not easy to crack and come off during stifled hole, there is not the potential safety hazard of falling behind the stifled hole; 2. horizontal reinforcement 2 is welded by Φ 8 round steel (can utilize on-the-spot steel scrap muscle) right-angled intersection, and is easy to use.Checkered steel plate 1 inboard is welded with M12 nut 3 as interior fixed block, and nut 3 is positioned at the lateral mid-point of trapezoidal steel plate, and it highly is 1/2～3/4 of a whole trapezoidal steel plate.Be inserted in the nut 3 with the longitudinal reinforcement 6 of horizontal reinforcement 2 welding, the cardinal principle centre position is welded with Φ 8 transverse reinforcements 4 on the longitudinal reinforcement 6, and its effect is a fixed form, prevents to rotate.Described longitudinal reinforcement 6 is corresponding with the vertebra angle of described cone table with the angle of horizontal reinforcement 2, and every checkered steel plate 1 periphery is welded with M10 nut 5 up and down as the external fixation piece, can easily it be linked to each other with on-the-spot reinforcing bar by iron wire, thus fixed mould.
Need to prove: the also available general steel plate of checkered steel plate 1 replaces, and only weak effect is a little.Checkered steel plate 1 also is not limited to adopt four, and its number needs is determined according to the concrete needs of job site; The little steel plate piece that nut 3 that is used for fixing and nut 5 be also available to offer endoporus replaces, as long as can realize being connected of longitudinal reinforcement 6 plug-in mountings and checkered steel plate 1 and on-the-spot reinforcing bar, that is realizes fixing of checkered steel plate 1.
