Description
Technical Field
The utility model relates to an accurate location regularization reinforcing bar of prefabricated stair installation belongs to the assembly type structure construction field.
Background
With the continuous development of modern building industry, the field operation work in the traditional construction mode is gradually transferred to a factory for carrying out, the components and accessories (such as floor slabs, wall plates, stairs, balconies and the like) used for the building are processed and manufactured in the factory, the components and accessories are transported to a building construction site, and the components and the accessories are assembled and installed on the site through a reliable connection mode, and the process is called as an assembly type building process. Prefabricated staircase is generally used to fabricated construction, adopts the prefabricated on-the-spot form of installing of mill, but accurate and quick location is a big difficult point between the current fabricated staircase, provides a prefabricated staircase installation accurate location regularization reinforcing bar for this.
Disclosure of Invention
The utility model provides an accurate location regularization reinforcing bar of prefabricated stair installation to solve the problem that current prefabricated stair is difficult to accurate and quick location.
For reaching above-mentioned purpose, plan to adopt such accurate location regularization reinforcing bar of prefabricated stair installation, reserve the dowel bar bottom including two and buckle 90 degrees, reserve a dowel bar bending position welding assistance-localization real-time muscle at two, prefabricated step board one end is vertical has seted up two mounting holes, and two mounting holes distribute along the width direction of prefabricated step board, and two reserve dowel bar intervals and two mounting hole center intervals of prefabricated step board, and the length of assistance-localization real-time muscle is prefabricated step board width and both sides side seam width sum.
In the above-mentioned regularization reinforcing bar, two reserve joint bars shape and size are the same, and two reserve joint bars are parallel just to setting up, and the auxiliary positioning muscle perpendicular to two reserve joint bars and respectively with the bending part welded fastening of two reserve joint bars.
Compare with not adopting this facility construction basement, the utility model discloses effectively solved the inaccurate problem in prefabricated stair pre-buried connecting piece location, the reinforcing bar of preparation regularization can adopt reinforcing bar waste material preparation, not only does not increase any cost, has realized recycling of reinforcing bar waste material simultaneously. Simultaneously this regularization reinforcing bar simple manufacture, simple to operate can realize the accurate high-efficient installation of prefabricated stair, ensures engineering progress and structural quality and safety, suitable popularization and application.

Detailed Description
To further clarify the objects, technical solutions and advantages of the present invention, the present invention will be described in detail with reference to the accompanying drawings, and it should be understood that the embodiments described herein are only used for the purpose of explanation and are not intended to limit the present invention.
Examples
Referring to fig. 1 to 4, this embodiment provides an accurate location regularization reinforcing bar of prefabricated stair installation, and two reserve joint bar (1) bottoms are buckled 90 degrees, reserve joint bar length according to on-the-spot reality. One phi 12 auxiliary positioning rib 3 is welded at the bending position of two reserved joint bars 1, the central distance between the two reserved joint bars 1 and the central distance between the two mounting holes 4 of the prefabricated stair step plate, and the length of the auxiliary positioning rib 3 is the sum of the width of the prefabricated stair step plate 5 and the width of the side seams at the two sides. Prefabricated 5 one end of step has two mounting holes 4, when 6 formwork erection of bracket accomplished the ligature reinforcing bar, hugs closely 6 template settings of bracket with this regularization reinforcing bar one end, fixes firmly can pour 6 concrete of bracket with bracket (6) reinforcing bar again. When 6 tops of bracket adopt 8 prefabricated step boards 5 of leveling of cement mortar, aim at dowel bar 1 and step board mounting hole 4 with two reservations of this regularization reinforcing bar, pour grouting material 9 again, the mounting hole top adopts 10 shutoff of mortar, and prefabricated step board 5 joint of sliding adopts polyphenyl board 12 and PE stick 13 to fill, and the side seam adopts cement mortar to fill, can reach the accurate high-efficient location installation of prefabricated stair.
The prefabricated staircase installation construction process specifically comprises the following steps:
(1) and (6) preparing hoisting. And calculating the length of a corresponding steel wire rope or sling according to the deepening design condition of the stair in advance before the prefabricated stair is hoisted. In order to ensure that the prefabricated staircase is accurately installed in place, the lengths of slings at two ends of the staircase need to be controlled, and the two ends of the staircase are required to be simultaneously descended onto a rest platform.
(2) And (5) hoisting the prefabricated staircase. The prefabricated staircase is hoisted by using the lifting hook and the long and short lifting ropes, two signalers are arranged during hoisting, one member is hoisted, and the other member is hoisted on a floor. In addition, when the stair is hoisted, one hook person is equipped, and 2 stair placing and fixing persons are equipped on the floor. Before hoisting, the type and the size of the stair are checked by a quality responsible person, after the quality is checked to be correct, a specially-assigned person is responsible for hooking, when the person who hooks withdraws to a safe area, the safety condition around the member is confirmed by a following signaler, the member is commanded to hoist slowly and hoisted to a position about 0.5m away from the ground, and the hoisting device of the tower crane continues hoisting after the safety is determined.
(3) And (6) mounting the prefabricated staircase. And (3) stopping slightly when the stair boards are hoisted to the position 500mm above the working surface, stabilizing the prefabricated stairs by professional operators, adjusting according to the direction of the stair boards, requiring slow operation when in place, and avoiding quick violent placing so as to avoid causing the damage of the stair boards due to earthquake and breakage. After the stair boards are basically in place, two reserved steel bars of the shaped steel bars are aligned, C40-grade CGM grouting material is poured into the fixing support mounting holes, and the top of the fixing support mounting holes is blocked by mortar. The prefabricated staircase sliding joint is filled with polystyrene boards and PE rods, and the side joint is filled with cement mortar.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
