For this reason, method of the present invention comprises the steps:
(1) prepare steel to punch large form, steel punches large form installing for inner-outer wall hole part wall form, the punch shape and size at large form hole of steel are identical with the shape and size of wall hole, and the steel large form hole outer peripheral face that punches flushes with wall hole outer peripheral face;
(2) prepare hole steel side plate, hole steel side plate is used for four side sealing holes punching two pieces between large form, and hole steel side plate width is that thickness of wall body and two pieces of steels punch large form thickness sum, and length is respectively hole four edge lengths;
(3) large form that hole steel side plate and steel punched in spacing distance bolt is fixed;
(4) the concrete construction of inner-outer wall hole part is carried out
(5) concreting completes and after reaching form removal condition, unloads hole steel side plate and steel and to punch large form, completes opening mould plate and exempts from the construction that wooden internal mold installs.
The punch shape and size at large form hole of steel are identical with the shape and size of wall hole.Described hole steel side plate is used for four the side sealing holes punched two pieces between large form.Perforate on steel side plate on the downside of described window hole, when preventing concreting, under window hole, side template place air is not discharged, and due to internal air pressure, causes concrete to build to fill full, causes hole, leaks the common quality defect such as muscle.
Said structure design reaches object of the present invention.
The present invention has method simple practical, and construction speed is fast, and structure is simple, can increase substantially construction quality, and reducing the construction costs.Concrete advantage is as follows:
(1) speed of application is fast.The wooden internal mold traditional relative to door and window hole place, this position template, without the need to prefabricated in advance, removes the complicated processes such as wooden internal mold scale processing from, and only need install shutoff steel side plate, construction technology is simple to operate.Meanwhile, after model sheetinstallat, the whole monobloc cast of wall, beam, removes from reserved or picks the operations such as cutter hitch, effectively shorten the duration and reduce cost.
(2) construction quality is good.Because shear wall door and window hole place template adopts steel plate to make, after form removal, this negative and positive angle, position concrete formation quality is good, and negative and positive angle is smooth straight, not the few angle of truncation.In addition, convenient inspection is opened wide at door and window hole position, and hole closure plate is steel closure plate, not off normal, do not rise mould, can at utmost ensure structure cross-section dimensions and dimension of opening.
(3) cost is reduced.Concrete smooth surface after the large formwork construction of steel door window hole is smooth, can reduce the later stage repair, the operation such as levelling, save artificial and material; Hole place side template adopts steel closure plate, and ensure that the mass defect of hole physical dimension and hole displacement, distortion, decrease the processing of opening wooden form, speed of application is fast, and turnover ability is strong, saves the duration.
(4) environmental protection, energy-conservation.Hole place template adopts steel template, disposable input, and repeatedly can have enough to meet the need use, also recyclable after finishing using, and reclaims residual value and accounts for original cost value 40%, relative to conventional wooden internal mold, both environmental protection, energy-conservation again.
