Detailed Description
The present application is described in further detail below with reference to figures 1-4.
The embodiment of the application discloses stair for assembly type building. Referring to fig. 1, the fabricated building staircase includes a flight stringer 1 and a tread 2. The bench sloping 1 is equipped with two, and two bench sloping 1 slope are arranged and mutual symmetry. The high both ends of bench sloping 1 are equipped with supporting part 11, and supporting part 11 level sets up, and supporting part 11 and bench sloping 1 structure as an organic whole. Be equipped with the hole for hoist 111 that is used for 1 hoist and mount of bench sloping on the supporting part 11, the supporting part 11 is used for 1 of bench sloping and erects the bearing structure between the floor and link to each other, and bearing structure can be concrete platform, also can be the support girder steel. The tread board 2 is arranged between the two ladder section sloping beams 1.
Referring to fig. 2, the top of bench sloping 1 is equipped with bolt 3 equally spaced, and step board 2 is equipped with the jack 21 with 3 looks adaptations of bolt, and bolt 3 stretches into and can avoid step board 2 to drop from bench sloping 1 in the jack 21, has reduced the potential safety hazard.
Referring to fig. 3, the longitudinal section of the tread 2 along the length direction of the ladder section stringer 1 is in the shape of a right triangle, the tread 2 is provided with oblique notches 22 at two acute angles, and the oblique angles of the two notches 22 are equal. The notches 22 of two adjacent step plates 2 are mutually abutted, and the step plates 2 are arranged step by step from the lower end along the higher end of the ladder section inclined beam 1. The step plate 2 at the lowest stage is supported in contact by the support portion 11.
During the installation hang ladder section sloping 1 to between two bearing structure through hoisting hole 111 earlier, two supporting parts 11 of ladder section sloping 1 respectively with bearing structure looks butt, then adjust after the distance between two ladder section sloping 1 fixed ladder section sloping 1, install step board 2 between two ladder section sloping 1 again, make in bolt 3 stretches into jack 21, two adjacent step boards 2 are in the mutual butt formation of incision 22 department and fix. The stair comprises bench sloping 1 and step board 2, and bench sloping 1 and step board 2 adopt two pairs of moulds to pour respectively, and the production technology is compared in adopting integral a pair to pour the purpose simpler to the component size obviously reduces, assembles simply, and it is convenient to dismantle, can obviously shorten the time limit for a project, reaches the purpose that makes production, transportation and the installation of stair all convenient.
Referring to fig. 3, the plug pin 3 includes a steel pipe 31 and a steel plate 32. One end of the steel pipe 31 is pre-buried in the ladder section sloping beam 1, and the steel plate 32 is welded and fixed at one end of the steel pipe 31 pre-buried in the ladder section sloping beam 1. When in processing, the bolt 3 is fixed in the template of the ladder section sloping beam 1 in advance, and then the ladder section sloping beam 1 is poured. The steel pipe 31 is used for fixing and limiting the step plate 2, the steel plate 32 enables the steel pipe 31 and the ladder section sloping beam 1 to be connected more stably, and the steel pipe 31 is not easy to break away from the ladder section sloping beam 1.
Referring to fig. 3, a mortar block is arranged between the plug pin 3 and the jack 21. When the step plate 2 is installed on the ladder section sloping beam 1, the steel pipe 31 of the bolt 3 is inserted into the insertion hole 21, then mortar is poured into the insertion hole 21 for plugging, and the mortar is poured into the installation hole and is flush with the top end of the step plate 2. Mortar has filled the gap between mounting hole and the fastener, has realized the reliable connection between step board 2 and bench sloping 1, makes step board 2 be difficult for producing and rocks.
Referring to fig. 3, a bearing member 4 is provided in the step plate 2. The bearing members 4 are binding reinforcing bars, and the bearing members 4 are fixed in the templates of the tread plates 2 in advance before the pouring of the tread plates 2 is performed. The bearing parts 4 strengthen the supporting function of the tread board 2, so that the bearing capacity of the tread board 2 is stronger and the tread board cannot be easily broken.
