Abstract
A three-step-upward construction method for stairs is provided to overcome the defect that with a three-step-upward construction method for stairs in the prior art, the elevation angles of stair flight board faces poured the last time and this time are inconsistent. The three-step-upward construction method for stairs includes the following steps that A, a floor slab template is installed; B, a template for a bottom plate of the last stair flight is installed, and the bottom of the template of the bottom plate of the last stair flight is connected with the floor slab template in the step A in an overlapped mode; C, stair steel bars are installed in the template of the bottom plate of the last stair flight in the step B; D, a three-step-upward stair flight stepping template is installed in the template of the bottom plate of the last stair flight in the step C; E, the template of the bottom plate of the last stair flight and the three-step-upward stair flight stepping template are sealed; F, concrete is poured into the floor slab template, the template of the bottom plate of the last stair flight and the three-step-upward stair flight stepping template; G, the poured concrete is maintained. The three-step-upward construction method for stairs can ensure that the elevation angles of the stair flight board faces poured the last time and this time are consistent, and the method is applicable to stair pouring environments.
Description
Technical field
The present invention relates to a kind of construction techniques, relate in particular to three step job practicess on a kind of stair.
Background technology
The position of carrying out should meeting when stair are built constuction joint is arranged on the requirement that structure is subject to the position of the less and constructability of shearing.Conventionally two race stair turning platform of starting to walk is nine grades of stair steps, and its minimum shearing place, greatly about 1/3 bench place, is therefore arranged on constuction joint three step places on stair when template construction, and custom is much of three step job practicess.Although adopt, can guarantee that in this way the position setting of constuction joint meets the requirements, but the waist slab face elevation angle of front and back two-step pouring is wayward, before and after causing, the waist slab face elevation angle of two-step pouring is inconsistent, occurs the disadvantages such as warpage, affects the overall appearance of stair.
Summary of the invention
The present invention overcome three step job practicess on stair of the prior art cause before and after the inconsistent shortcoming in the waist slab face elevation angle of two-step pouring, three step job practicess on the consistent stair in the waist slab face elevation angle of two-step pouring before and after a kind of can assurance are provided.
The technical scheme that the present invention realizes goal of the invention employing is: three step job practicess on a kind of stair, comprise the following steps:
A., flooring flat panel form is installed;
B. install a bench base plate template, the length of whole section of stair step of the length of a described upper bench base plate template and a upper bench is corresponding, the bottom of a upper bench base plate template and the overlap joint of the flooring flat panel form described in steps A;
C. in the upper bench base plate template described in step B, carry out stair reinforcement installation;
D. in the upper bench base plate template described in step C, install the three step bench template of marking time;
E. a upper bench base plate template and the upper three step bench template of marking time is sealed to processing;
F. to flooring flat panel form, a upper bench base plate template and the upper three step bench concreting in template of marking time;
G. the concrete of building is carried out to maintenance.
Described step B also comprises, measures a upper bench half space absolute altitude, and the top of a upper bench base plate template of installation and the horizontal level of this absolute altitude coincide, to control the elevation angle of a upper bench base plate template.
The invention has the beneficial effects as follows: mark time before template and first install a bench base plate template installing three step bench, the pedal template of the stair of front and back two-step pouring is installed in a bench base plate template, during a rear construction casting concrete, only need cut to stair construction joint general processing the such as loosening concrete, the elevation angle that put with a upper bench base plate template at the elevation angle of the stair of front and back two-step pouring is consistent, the inconsistent shortcoming in the waist slab face elevation angle of two-step pouring before and after effectively having solved.
On determining during the setting angle of a bench base plate template, one top of bench base plate template and the height level position of half space are coincided, because the height of half space is a fixed value, can effectively guarantee that the elevation angle that on every one deck, a bench base plate template is installed is identical, after having built, the stair elevation angle of every floor is identical, has guaranteed the attractive in appearance of entire building ladder.
Below in conjunction with accompanying drawing and the specific embodiment, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is flow chart of the present invention.
The specific embodiment
As shown in drawings, three step job practicess on a kind of stair of the present embodiment, comprise the following steps:
A., flooring flat panel form is installed;
B. install a bench base plate template, the length of whole section of stair step of the length of a described upper bench base plate template and a upper bench is corresponding, the width of a upper bench base plate template is corresponding with the width of the upper every rank of bench stair, the bottom of a upper bench base plate template and the overlap joint of the flooring flat panel form described in steps A, the seam of two boards should meet the requirements; Identical for guaranteeing the stair elevation angle of every floor, the preferred step of the present embodiment also comprises measures a upper bench half space absolute altitude, and the top of a upper bench base plate template of installation and the horizontal level of this absolute altitude coincide, to control the elevation angle of a upper bench base plate template; Before installing a bench base plate template, should first set up the form bracing systems such as steel pipe framed bent, first set up steel pipe support below, a upper bench base plate template is above installed;
C. in the upper bench base plate template described in step B, carry out stair reinforcement installation;
D. in the upper bench base plate template described in step C, install the three step bench template of marking time, in a upper bench base plate template, put baffle plate one by one, two ends reinforce with step fastener;
E. a upper bench base plate template and the upper three step bench template of marking time is sealed to processing, at template top, baffle plate is set, while preventing from building, concrete outwards flows out;
F. to flooring flat panel form, a upper bench base plate template and the upper three step bench concreting in template of marking time;
G. the concrete of building is carried out to maintenance, prevent that concrete coagulation is too fast, or there is the situations such as cracking in dry weather.
On common stair, in three step job practicess, increase the step of installing a bench base plate template, the inconsistent shortcoming in the waist slab face elevation angle of two-step pouring before and after effectively having solved.While installing a bench base plate template, the horizontal level of its top and a upper bench half space is coincided, to control the elevation angle of a upper bench base plate template, because the height of half space is a fixed value, the stair elevation angle of every floor is identical, has guaranteed the attractive in appearance of entire building ladder.
