Abstract
The invention discloses an integral stair tread formwork installation method including the steps of (1) prefabricating a stair tread formwork according to the drawing dimension, (2) hoisting the stair tread formwork integrally to the bound reinforcement by a tower crane, (3) determining the horizontal position of the stair tread formwork, (4) controlling stair height, (5) padding the formwork by cushions and battens before reinforcing, (6) binding the bottom battens and reinforcement by iron wires on the lower portion of the stair tread formwork so as to fix the bottom thereof primarily, (7) repeating the step (6), (8) firmly nailing the bottom plate and the wall forms by nails, and (9) stripping the forms. The stair tread formwork is manufactured integrally and is installed and detached integrally, and each section of the stair tread formwork can be fixed by two lead screws, dimension consistency of treads is guaranteed, and repeated computing, installing and detaching are avoided.
Description
Technical field
The present invention relates to a kind of mounting method of whole stair step template, belong to stair step formwork erection technical field.
Background technology
Algeria's social security Housing Project is on the high side, is generally R+5 layer house, and each layer of stair size is all consistent.The shuttering supporting of stair is considered to the operation that technical difficulty is very large, especially the template of marking time, he requires workman to want accurately to calculate the size that each is marked time, then install one by one, remove one by one. because workman's technical level there are differences, a lot of stair because early stage formwork size not to having caused inconvenience to follow-up fitting-out work, have even to cutting the stage of stair.Traditional stair step template exists and installs complex steps, and amount of calculation is large, and workman's operation easier is large, the problems such as labor productivity is low, waste material.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is, a kind of integral installation is provided, integral disassembly, assembly, adopt every race two rhizoid bars just can be fixed, guarantee the consistent of each size of marking time, avoided the mounting method of the whole stair step template that computes repeatedly, install, remove.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of mounting method of whole stair step template, it is characterized in that, and carry out as follows:
(1), according to the figure paper size precast stair template of marking time;
(2), stair step template is lifted on the reinforcing bar that colligation is good by tower crane whole;
(3) thereby, by confirming that the position of stair first step baffle plate determines the position of whole extension stair, according to figure paper size, utilize the axis of dull and stereotyped upper beam to measure 2 points with meter ruler, move gently stair template and make stair first step baffle plate just in time drop on above at these 2, thereby confirm the horizontal level of stair step template;
(4), stair height is controlled: first runs down standard laid down by the ministries or commissions of the Central Government coca measures according to 50cm line, the first race top absolute altitude and second is run down standard laid down by the ministries or commissions of the Central Government coca and is confirmed according to half space soffit formwork height, stair second run top absolute altitude to be confirmed by floor bottom elevation, thereby by level and vertical position, can determine the position of tread;
(5), before reinforcing, first with cushion block and flitch, cushion template to guarantee its invariant position;
(6), in stair step template bottom, with iron wire, bottom flitch and reinforcing bar are tied bottom is tentatively fixed;
(7), in stair step template bottom, with iron wire, bottom flitch and reinforcing bar are tied bottom is tentatively fixed;
(8), with nail by stair base plate and foreign countries' template stickfast, stair step formwork erection is complete;
(9), form removal: after pouring concrete, will form removal after concrete reaches certain intensity, first be to remove split bolt, then remove stair foreign countries, finally with hammer, beat backward stair step baffle plate, after activity, with tower crane, directly hang out gently, after form removable, will carry out timely cleaning brush oil, reparation, to treat use next time.
The advantage of the mounting method of the whole stair step template of the present invention is: the new stair step formwork support method of Di Bazha project management department independent research, stair step template construct is become to an integral body, integral installation, integral disassembly, assembly, adopt every race two rhizoid bars just can be fixed, guaranteed the consistent of each size of marking time, avoided computing repeatedly, install, removed.
The specific embodiment
Below in conjunction with specific embodiment, the present invention is described in further details;
A mounting method for whole stair step template, is characterized in that, carries out as follows:
(1), according to the figure paper size precast stair template of marking time, only need be by stair template cleaning brushing release agent while reusing.
(2), stair step template is lifted on the reinforcing bar that colligation is good by tower crane whole;
(3) thereby, by confirming that the position of stair first step baffle plate determines the position of whole extension stair, according to figure paper size, utilize the axis of dull and stereotyped upper beam to measure 2 points with meter ruler, move gently stair template and make stair first step baffle plate just in time drop on above at these 2, thereby confirm the horizontal level of stair step template;
(4), stair height is controlled: first runs down standard laid down by the ministries or commissions of the Central Government coca measures according to 50cm line, the first race top absolute altitude and second is run down standard laid down by the ministries or commissions of the Central Government coca and is confirmed according to half space soffit formwork height, stair second run top absolute altitude to be confirmed by floor bottom elevation, thereby by level and vertical position, can determine the position of tread;
(5), before reinforcing, first with cushion block and flitch, cushion template to guarantee its invariant position;
(6), in stair step template bottom, with iron wire, bottom flitch and reinforcing bar are tied bottom is tentatively fixed;
(7), in stair step template bottom, with iron wire, bottom flitch and reinforcing bar are tied bottom is tentatively fixed;
(8), with nail by stair base plate and foreign countries' template stickfast, stair step formwork erection is complete;
(9), form removal: after pouring concrete, will form removal after concrete reaches certain intensity, first be to remove split bolt, then remove stair foreign countries, finally with hammer, beat backward stair step baffle plate, after activity, with tower crane, directly hang out gently, after form removable, will carry out timely cleaning brush oil, reparation, to treat use next time.
New technology becomes an integral body by stair step template construct, integral installation, integral disassembly, assembly, a large amount of nails and fixed routine have been saved, every race only just can be fixed with the split bolt bar of two double headed roller silks, simple to operate, as long as 2 general of form fixers of technology turn out for work and can complete this stair step formwork erection method and have simple to operate, be easy to installation and removal, the workman that technology is general can grasp through simple training, and every extension stair can be saved the cost of materials of 2 labour costs of turning out for work and 2.3 kilograms of nails.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
