Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a novel cast-in-place concrete stair tread shaping steel mold comprises two side plates 1, a plurality of middle plates 2 and a bottom groove 3; the two side plates 1 are arranged on the inner side of the bottom groove 3, each side plate 1 is tightly attached to the inner bottom surface and the inner side wall of the bottom groove 3 at the same time, one side, far away from the inner bottom surface of the bottom groove 3, of each side plate 1 extends outwards from the inner part of the bottom groove 3 upwards, a plurality of second slots 301 arranged in the vertical direction are formed in the two side walls of the bottom groove 3, through channels 302 arranged in the length direction of the through channels are formed in the two side walls of the bottom groove 3, and the through channels 302 sequentially penetrate through the second slots 301; first slot 201 has all upwards been seted up to the position department that the bottom side of intermediate lamella 2 is close to its both ends, through-hole 202 has all been seted up to the position department that intermediate lamella 2 is located two first slots 201 outsides, two curb plate 1 insert respectively to two first slots 201 in, the position and the cooperation of pegging graft of second slot 301 that intermediate lamella 2 is located two curb plate 1 outsides, and after the both sides of intermediate lamella 2 inserted in second slot 301, through-hole 202 set up with the axle center with link up passageway 302, screw rod 4 has been inserted jointly with the inside that link up passageway 302 to through-hole 202 this moment, threaded sleeve 401 has been cup jointed to the equal screw thread in both ends of screw rod 4. Through the technical scheme, the novel cast-in-place concrete stair tread shaping steel die is characterized in that after two side plates 1 are installed in a bottom groove 3, a plurality of middle plates 2 are sequentially inserted into the two side plates 1, two sides of each middle plate 2 are inserted into second slots 301, a screw rod 4 simultaneously penetrates through a through hole 202 of each middle plate 2 and a through channel 302 of the bottom groove 3, then threaded sleeves 401 at two ends of the screw rod 4 are screwed down, the screw rod 4 is fixed, and therefore stable installation among the side plates 1, the middle plates 2 and the bottom groove 3 is achieved, the installation process is simple and rapid, only four threaded sleeves 401 need to be screwed down, when the die needs to be disassembled, only four threaded sleeves 401 need to be screwed down, the novel cast-in-place concrete stair tread shaping steel die is quite convenient and rapid, and under the action of the screw rod 4 and the threaded sleeves 401, the middle plates 2 and the bottom groove 3 can be stably installed, meanwhile, the side plate 1 can be firmly clamped between the middle plate 2 and the bottom groove 3, and the whole structure is very firm.

Further, the intermediate lamella 2 is multilayer steel sheet welded structure, connects through the mode of spot welding between the multilayer, and such structure makes intermediate lamella 2 have higher intensity, and the holding capacity is stronger, and when the steel sheet in the intermediate lamella 2 outside received corruption or damage, only need beat down this steel sheet and change again can, and need not the monoblock and change.

Further, the thickness of the middle plate 2 is equal to the width of the second slot 301, so that the connection between the middle plate 2 and the bottom slot 3 is tighter.

Further, the outer wall at 4 both ends of screw rod is the smooth surface, as shown in fig. 2, when needs pull down polylith intermediate lamella 2 simultaneously, only need two people hold the both ends of screw rod 4 simultaneously and upwards lift up can, it is very convenient to dismantle, and the outer wall at 4 both ends of screw rod can be convenient for operating personnel to grip and lift up screw rod 4 for the smooth surface to strain the palm because of the screw thread.

Further, the sidewall of the threaded sleeve 401 is multi-faceted, which facilitates rotational adjustment of the threaded sleeve 401 by a tool (e.g., wrench, pliers, etc.).

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
