Detailed Description
The technical scheme in the embodiment of the application aims to solve the problems in the background technology, and the general thought is as follows:
Referring to fig. 1-4, an assembled prefabricated staircase includes two side plates 10 and steps 20, wherein the side plates 10 are provided with two vertical rods 30 exposed on the side plates 10, the steps 20 are L-shaped, the steps 20 are paved on the side plates 10, tapered pouring holes are formed in the steps 20, and the vertical rods 30 are located in the pouring holes. Wherein, two curb plates 10 are vertical to be placed, and the increase of vertical thickness is less to the dead weight influence to the advantage of being convenient for transport and build has been kept in guaranteeing intensity, utilizes conical pouring hole to form the concrete block of back taper and plays the effect of anchor to step 20, has improved joint strength, and montant 30 also is convenient for step 20 and directly places on curb plate 10, requires for a short time to peripheral space, and the commonality is stronger.
Referring to fig. 1-4, two ends of the side plate 10 are respectively connected with a lap joint 40, and the lap joint 40 is a part of an external building. Here, the lap portion 40 is a part of the external building, and requires reinforcement treatment in order to have sufficient strength to support the weight of the entire stairway.
Referring to fig. 1-4, hanging plates 50 are disposed at two ends of the side plate 10, and hanging grooves adapted to the hanging plates 50 are formed on the overlapping portion 40. Here, during splicing, the two side plates 10 are respectively hung on the upper and lower overlapping parts 40 through the hanging plate 50, the hanging plate 50 provides lateral limit for the stairs, and in this embodiment, the hanging plate 50 and the side plates 10 are integrally formed to ensure strength.
Referring to fig. 3-4, the cross bar 60 is exposed on the hanging plate 50, the lap joint portion 40 is provided with a pouring groove, and the cross bar 60 is located in the pouring groove. Here, the stairs are concaved downwards when being stressed, the hanging plates 50 at the two ends are folded inwards, the cross bars 60 are positioned in the pouring grooves, and after concrete is poured, longitudinal limiting is provided for the stairs.
Referring to fig. 1-4, the hanging plates 50 protrude from the lap joint portion 40, and support rods 70 are movably inserted into the two hanging plates 50. Here, after the two side plates 10 are placed, the support bar 70 is transversely passed through the two side plates 10, and then the two side plates 10 are connected together after concrete is poured, and the support area of the whole stair and the lap joint portion 40 is increased, so that the stress concentration of the lap joint portion 40 is reduced, and if the whole support bar 70 passes through the two side plates 10, a space is required on the side surface, and if the space on the side surface is insufficient, a mode that the two support bars 70 respectively pass through the two side plates 10 can be adopted.
Referring to fig. 1-4, the surfaces of the vertical bar 30, the horizontal bar 60 and the supporting bar 70 are provided with lines. Here, the vertical bars 30 and the horizontal bars 60 are exposed portions of the pre-buried rebar of the side plates 10 and the steps 20, and the support bars 70 are separate rebar.
