Abstract
The invention provides a multi-story shaped stair construction method, which belongs to the technical field of building construction and is characterized by comprising the following operation steps for implementation completion: 1, construction preparation is made; 2, a template is installed; 3, a stair or a steel mold device is installed; 4, the height and the inclination degree of a main beam are regulated; 5, concrete is cast, and in addition, steps are formed; 6, concrete fixing plates and connected parallel extending parts are cast; 7, after the concrete casting is completed, the stair steel mold device is dismounted; 8, the operation steps of 1 to 7 are repeated, the second floor stair construction is completed; 9, the operations are repeated in such a way until the erection and pavement construction of multi-story stairs is completed. After the implementation, the multi-story shaped stair construction method has the beneficial effects that the integral shaped stair steel mold device is adopted for replacing the existing wood mold scattered splicing method, the work production efficiency is greatly improved, the labor is saved, meanwhile, the materials are saved, the cost is reduced, more importantly, the construction quality is improved, the common quality fault is reduced, and the method belongs to a practical stair construction method.
Description
Technical field
Belong to technical field of building construction, exactly relate to the design and construction technology of building operations aid.
Background technology
Stair template construction one is to more complicated, the maximum of large family expenses are to construct with loose spelling of wooden template before, but due to the complexity of construction, often quality can not be guaranteed, the a lot of of sideslip mark time, do not reach construction requirement, the mass defect of most stair constructions need to be covered by finishing reparation.For this reason, be badly in need of a kind of practical new technology that can improve stair construction quality and reduce labour cost of development.
Summary of the invention
The invention provides the one that can improve stair construction quality and reduce labour cost simple to operate for many floors regularization stair construction method.
The technical scheme that the present invention takes:
For many floors regularization stair construction method, comprise preparation of construction, its scheme is: comprise following operating procedure and implemented:
1) preparation of construction, described preparation of construction, is to build to provide fixing concrete support plate for stair two ends; On the upper and lower laminate of shelving stair, vertically stretch respectively straight-bar; Described straight-bar is threaded, is overlapping the nut that regulates girder height on screw thread, and the base plate with small sircle hole is vertically being welded in straight-bar lower end;
2) installation form, shelving two interlayers up and down of stair, shelves the installation form of the anchoring of tiling obliquely;
3) stair steel die device is installed: be arranged in template superimposed stair steel die device, and hole on the horizontal channel-section steel of two parallel channel-section steels is inserted respectively in upper and lower straight-bar;
4) regulate girder height and gradient: adjusting nut is adjusted the antenna height of girder, and be adjusted to and meet stair gradient;
5) concreting form step: build stair step concrete step; The floating formation step of marking time;
6) concreting fixed head and the coupled part that extends in parallel, as the new stair base plate of next level;
7) after completing, concreting removes stair steel die device;
8) repeat 1)-7) operating procedure, complete the construction of second layer stair;
9) aforesaid operations so repeatedly, until many floors stair frame paving has been constructed.
The good effect of implementing after the present invention is:
Adopt integral forming stair steel die device to replace the loose splicing method of wooden model in the past, greatly improved labor productivity, in economization labour, save material, reduced cost, the most important thing is to have promoted construction quality, having reduced common quality defect, is a practical stair construction method.

Detailed description of the invention
Now the invention will be further described by reference to the accompanying drawings
For many floors regularization stair construction method, comprise preparation of construction, it is characterized in that: implemented by following operating procedure:
1) preparation of construction, described preparation of construction, is to build to provide fixing concrete support plate for stair two ends; On the upper and lower laminate of shelving stair, vertically stretch respectively straight-bar 6,4; Described straight-bar is threaded, is overlapping the nut 8 that regulates girder height on screw thread, and the base plate 5 with small sircle hole 7 is vertically being welded in straight-bar lower end;
2) installation form, shelving two interlayers up and down of stair, shelves the installation form of the anchoring of tiling obliquely;
3) stair steel die device is installed: be arranged in template superimposed stair steel die device 11, and hole on the horizontal channel-section steel of two parallel channel-section steels is inserted respectively in upper and lower straight-bar 6,4;
4) regulate girder height and gradient: adjusting nut 8 is adjusted the antenna height of girder, and be adjusted to and meet stair gradient;
5) concreting form step: build stair step concrete step; The floating formation step of marking time;
6) concreting fixed head 10 and the coupled part that extends in parallel, as the new stair base plate of next level;
7) after completing, concreting removes stair steel die device;
8) repeat 1)-7) operating procedure, complete the construction of second layer stair;
9) aforesaid operations so repeatedly, until many floors stair frame paving has been constructed.
Described stair steel die device 11, there is carrying main beam, described carrying main beam 1 is settled by stair gradient, two parallel channel-section steels that both ends horizontal outwards extends in parallel, girder downside is by stair step spacing, equally spaced welding modification of right-angled triangle plate 2 hypotenuses that are made up of steel plate, the right-angle side of vertical ground is welding vertical step plate 3, substitutes welding modification of right-angled triangle plate hypotenuse at the horizontal initiating terminal of lower end by welding rectangular slab; On the channel-section steel of both ends horizontal epitaxial end, there are respectively two through holes on break-through channel-section steel limit, straight-bar 4 is through two through holes, the base plate 5 with small sircle hole 7 is vertically being welded in straight-bar lower end, four straight-bars 6 of two floor ladder connections, be positioned on the channel-section steel with holes that is called Bolt to position beam 9, entirety forms stair steel die device 11.
