Abstract
The utility model discloses a prefabrication type assembled stairway. The prefabrication type assembled stairway comprises a prefabricated stairway body (6) and a platform (7). The prefabrication type assembled stairway is characterized in that a plurality of first plug pins (11) are installed on the bottoms of the two ends of the prefabricated stairway body (6) at certain intervals, transverse pins (3) are arranged on the upper portions of supporting plates (5), vertical pins (1) are arranged on the lower portions of the supporting plates (5), the transverse pins (3) are inserted into fourth insertion holes (8), the vertical pins (9) are inserted into second insertion holes (9), and second oblique notches (14) are formed in the bottoms of the supporting plates (5). According to the prefabrication type assembled stairway, building components are well machined in a factory in advance, assembly can be conducted directly after the building components are conveyed to a site, the construction processes are simplified, and the construction period is greatly shortened.
Description
Technical field
The utility model relates to stair, and especially a kind of prefabricated assembling stair, belong to building structure technical field.
Background technology
Stair are one of very important structural element in Residential structure, and generally, stair adopt cast-in-situ concrete to build.Cast-in-situ stair deadweight is large especially, and poor because of template versatility, and cost is also higher, in addition, and as cannot be lift by the restriction of tower crane elevating capacity.Simultaneously concrete staircase generally adopts the way of pouring concrete after first assembling reinforcement, and this method exists complicated construction technique, the technological deficiency that the engineering time is long.
Summary of the invention
The utility model is in order to solve the existing the problems referred to above of prior art, provides a kind of structural performance reliable, and quality is light, the simple prefabricated assembling of construction technology stair.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of prefabricated assembling stair, comprise precast stair main body and platform, it is characterized in that: bottom, described precast stair main body two ends is provided with several latches one at a certain distance, above platform, be provided with the jack corresponding with several latches one one, described latch one is inserted in jack one the inside, is also respectively equipped with at a certain distance jack two and jack three above described precast stair main body; Described precast stair main body top is provided with pedal, and described pedal one end is provided with jack four, the other end is provided with angle one, is provided with support in the middle of described pedal, and jack three inside are inserted in described support; Described precast stair main body top is also provided with gripper shoe, and described gripper shoe top is provided with horizontal stroke, below is provided with perpendicular pin, and described lateral pin inserts jack four inside, perpendicular pin inserts jack two inside, and described gripper shoe bottom is provided with angle two.
Described angle one angle is identical with precast stair main body mounting inclination angle degree.
Described angle two angles and precast stair main body mounting inclination angle degree mutually more than.
Described latch one, support, lateral pin and perpendicular pin are the round steel of diameter 12mm.
Described jack one, jack two, jack three and jack four diameters are 13mm.
Compared with prior art, the utility model prefabricated assembling stair have the following advantages: 1, required constructional materials is all prefabricated in advance in factory in advance, are transported to rear directly assembling now, do not need to carry out deep processing, reduce building waste; 2, each assembly quality is light, to on-the-spot direct labor assembling, need not want the help of crane gear, can Fast Installation, and the construction period is shortened greatly; 3, simple in structure, dismounting aspect, has reduced the technical quality requirement to workman.
