DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.
[0027] As Figures 1 to 4 shown, a device for reserving the construction floor alignment hole in this embodiment includes multiple steel plates. All the multiple steel plates are isosceles trapezoidal steel plates. The waist sides of the multiple steel plates are sequentially hinged through hinge shafts. The two steel plates at the head and tail are clamped and positioned through a clamping structure. The multiple steel plates enclose to form a polygonal cone structure. A cover plate 9 is hinged on one of the steel plates at the large opening end of the polygonal cone structure. The cover plate 9 can cover and block the large opening end of the polygonal cone structure. An installation handle 10 is further provided on the outer side wall of the polygonal cone structure.
[0028] Preferably, the multiple steel plates in this embodiment are of the same size.
[0029] As Figures 1 to 4As shown, preferably, the multiple steel plates include a first steel plate 1, a second steel plate 2, a third steel plate 3, and a fourth steel plate 4. One waist side of the first steel plate 1 is hinged to one waist side of the second steel plate 2 through a first hinge shaft 5. The other waist side of the second steel plate 2 is hinged to one waist side of the third steel plate 3 through a second hinge shaft 6. The other waist side of the third steel plate 3 is hinged to one waist side of the fourth steel plate 4 through a third hinge shaft 7. The other waist side of the fourth steel plate 4 abuts against the other waist side of the first steel plate 1 to form a quadrilateral cone barrel structure, and the outer side wall of the fourth steel plate 4 is clamped and positioned with the outer side wall of the first steel plate 1 through a clamping structure.
[0030] Specifically, as Figures 1 to 4 shown, an installation handle 10 is provided on the outer side walls of the second steel plate 2 and the fourth steel plate 4 respectively. The setting of the installation handle facilitates operation.
[0031] As Figures 2 to 4 shown, the extending direction of the installation handle 10 in this embodiment is perpendicular to the central axis of the quadrilateral cone barrel structure.
[0032] As Figures 2 to 4 shown, the cover plate 9 in this embodiment is hinged to the third steel plate 3 at the large opening end of the quadrilateral cone barrel structure through a fourth hinge shaft 8.
[0033] As Figures 2 to 3 shown, the cover plate 9 in this embodiment is a square cover plate.
[0034] As Figures 1 to 4 shown, the clamping structure in this embodiment includes an angle steel clamping member 12 and a steel plate clamping member 13. The angle steel clamping member 12 is fixed on the outer side wall of the first steel plate 1. The steel plate clamping member 13 is fixed on the outer side wall of the fourth steel plate 4. A part of the steel plate clamping member 13 extends beyond the other waist side of the fourth steel plate 4 and a clamping groove 14 is formed in the extending part. A part of the angle steel clamping member 12 extends beyond the other waist side of the first steel plate 1, and the part of the angle steel clamping member 12 extending beyond the other waist side of the first steel plate 1 is clamped in the clamping groove 14. By providing the angle steel clamping member and the steel plate clamping member, a clamping structure can be formed after mutual clamping, making the structure of the quadrilateral cone barrel structure more stable after enclosing.
[0035] As Figures 1 to 4 shown, the steel plate clamping member 13 in this embodiment is of a strip-shaped structure. The opening direction of the clamping groove 14 is arranged towards the large opening end of the quadrilateral cone barrel structure. The corner bending part of the angle steel clamping member 12 is arranged perpendicular to the central axis of the quadrilateral cone barrel structure. One side wall of the angle steel clamping member 12 is arranged towards the small opening end of the quadrilateral cone barrel structure and is clamped in the clamping groove 14.
[0036] As Figures 1 to 4 shown, a limiting cross bar 11 is also welded on the outer side wall of each steel plate in this embodiment. The arrangement of the limiting cross bar can form a clamping connection with the concrete structure when pouring concrete, preventing the quadrilateral cone structure from shifting during the concrete pouring process.
[0037] As Figures 1 to 4 shown, the limiting cross bar 11 in this embodiment is arranged perpendicular to the central axis of the polygonal cone structure, and a plurality of limiting cross bars 11 enclose to form a polygonal structure.
[0038] When manufacturing the building floor setting-out hole reservation device in this embodiment, first, trapezoidal steel plates with appropriate sizes need to be cut according to the actual situation on site. The width and height of the steel plates need to be made according to the actual reserved hole size on site and the designed plate thickness. After manufacturing, the limiting cross bars are welded according to the floor slab thickness first. After welding, four trapezoidal steel plates are connected and fixed by using movable hinge shafts and the clamping structure is welded. After the overall connection and fixation are completed, the clamping structure is closed and fixed. Subsequently, the handle is welded, the cover plate is connected to the corresponding steel plate, and after the whole is completed, the surface is polished smoothly and a release agent is applied for use. When in use, after the formwork of the structural floor is erected, suitable holes are opened at the formwork position according to the required hole size (note that the size of the opened holes needs to be determined according to the floor slab thickness and the distance between the limiting cross bar and the upper surface of the formwork). The reservation device is coated with a release agent and then can be put into the formwork hole position for use.
[0039] The building floor setting-out hole reservation device in this embodiment adopts a polygonal cone structure formed by connecting multiple steel plates end to end, which can be set in the concrete structure to be poured. After pouring concrete, a setting-out hole can be formed, which can reduce the deformation and displacement caused by vibration and concrete extrusion during the concrete pouring process. After coating with a demoulding agent, it can be reused and is very convenient to remove, which can effectively improve the work efficiency of setting-out construction.
[0040] The building floor setting-out hole reservation device in this embodiment is made of steel material, with high overall strength, a flat surface, and can be repeatedly used. It can avoid the deformation and displacement of the reserved holes caused by vibration and concrete extrusion during the concrete pouring process, save the construction time of setting-out lead wires, reduce the labor intensity of workers, reduce the construction cost, and improve the construction efficiency.
