Detailed Implementation
[0024] The following will describe specific embodiments and appendices. Figures 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0025] This utility model provides an adjustable staircase casting mold assembly (such as...). Figure 1As shown, the structure includes a horizontal support section, a diagonal brace section, and a baffle section. The horizontal support section includes two sets of support frames 11, and the diagonal brace section is located between the two sets of support sections 11. In practical applications, the two support sections 11 are used to achieve stable support for the diagonal brace section. At the same time, the two support sections 11 are used to achieve stable placement of the entire structure on the building support platform 6. The diagonal brace section can be adjusted and positioned relative to the two sets of support frames 11. The adjustable tilt angle of the diagonal brace section facilitates the pouring construction of stairs with different tilt angles using this structure. The baffle section includes several sets of baffle assemblies, which are arranged on the diagonal brace section. The baffle assemblies can be adjusted and positioned vertically. Each set of baffle assemblies includes several baffles 32 of different models. In this specific embodiment, different models of baffles 32 refer to differences in the length and vertical height of the baffles 32. In practical applications, the baffle 32 obstructs the pouring of concrete, enabling the initial shaping of the stair treads and facilitating the smooth pouring of the staircase. By adjusting the inclination angle of the diagonal brace and the horizontal spacing between adjacent baffles 32, stair treads of different widths can be supported. By replacing different models of baffles 32, stair treads of different vertical heights or lengths can be supported, thus improving the flexibility of this invention. In practical applications, all components of this invention can be made of steel, possessing high structural strength. Furthermore, high-precision dimensional processing can be performed in the factory according to actual needs, thereby improving the forming quality of the staircase. During the formwork process, this invention allows for pre-assembly and overall formwork erection and dismantling, thereby improving the efficiency of staircase pouring.
[0026] Based on the above embodiments, the specific implementation of the support frame 11 is as follows: The support frame 11 includes an I-beam frame, on which two adjustable support legs are provided. The height of the I-beam frame can be adjusted using the adjustable support legs, thereby facilitating the adjustment of a reasonable tilt angle by the support frame 11 in conjunction with the diagonal brace. Specifically, the adjustable support legs include an adjusting external threaded tube 113 and a support tube 1131. The bottom of the adjusting external threaded tube 113 is fixedly connected to the upper part of the support tube 1131. The upper part of the adjusting external threaded tube 113 is sleeved on a first fixing nut 114 fixedly provided on the outer end of the I-beam frame. The I-beam frame can be composed of two first U-shaped steels 111 and a second connecting rod 112. In the middle, the two ends of the second connecting rod 112 are respectively fixedly connected to the inner side of the corresponding first U-shaped steel 111 by bolt connection. Two upper and lower supporting ears are provided on the inner side of each first U-shaped steel 111. Through holes are opened in the supporting ears. The first fixing nut 114 is fixed on the upper supporting ear, and the first fixing nut 114 is connected to the through hole on the supporting ear. The adjusting external thread 113 is sleeved on the corresponding supporting ear and the first fixing nut 114. In actual application, the height of the entire I-beam can be adjusted by rotating the adjusting external thread rod 113. The self-locking principle of the threaded engagement relationship can be used to ensure that the I-beam is positioned on the adjusting external thread tube 113 without rotating the adjusting external thread rod 113.
[0027] Based on the above embodiments, the specific implementation of the diagonal brace is as follows: The diagonal brace includes two diagonal bracing rods 21 that are relatively parallel to each other. In actual processing, the diagonal bracing rods 21 can be directly processed from U-shaped steel. The two diagonal bracing rods 21 are fixedly connected by two first connecting rods 22. Specifically, the first connecting rods 22 can be fixedly connected to the corresponding diagonal bracing rods 21 by bolt connection. After the fixed connection is achieved, the two first connecting rods 22 are located between the two diagonal bracing rods 21. The ends of the diagonal bracing rods 21 are hinged to the ends of the corresponding I-beams. A locking component for limiting the rotation of the diagonal bracing rods 21 is provided on the I-beams. The specific implementation of the hinged connection between the ends of the diagonal bracing rods 21 and the I-beams is as follows: A first connecting plate 115 is fixedly provided on both ends of the inner side of the I-beams, that is, a first connecting plate 115 is fixedly provided on the end of each first U-shaped steel 111 corresponding to the diagonal bracing rod 21. A locking component for limiting the rotation of the diagonal bracing rods 21 is provided on the ends of the diagonal bracing rods 21. The second connecting plate 211 corresponding to the first connecting plate 115 has a first elongated hole 1151 in the middle of the first connecting plate 115. A first hinge plate 212 is fixedly mounted on the second connecting plate 211 and placed inside the corresponding first elongated hole 1151. A pin hole is provided at the outer end of the first hinge plate 212, and a pin 213 is fitted inside the pin hole. In actual application, to facilitate the first hinge plate 212 to rotate around the pin 213 to a certain extent... In the rotational motion, a first fixed support lug 1152 is fixedly provided on both sides of the first elongated hole 1151. A through hole corresponding to the pin 213 is provided on the first fixed support lug 1152. The pin 213 is sleeved on the two first fixed support lugs 1152, thereby realizing the limitation of vertical and horizontal movement. The first hinge plate 212 can swing vertically within the corresponding first elongated hole 1151. The smooth swing of the first hinge plate 212 facilitates the adjustment of the tilt angle of the diagonal brace 21.Further, the specific implementation of the locking assembly is as follows: the locking assembly includes an adjusting screw 117 and a second fixing nut 116. A first through hole is provided at each of the four corners of the first connecting plate 115. A second fixing nut 116 is fixedly provided on the outside of each first through hole. The adjusting screw 117 is sleeved on the second fixing nut 116, and the adjusting screw 117 passes through the corresponding first through hole. In actual application, by controlling the upper and lower sides of the first hinge plate 212... The extension length of the adjusting screw 117 on the side allows for the adjustment and fixing of the tilt angle of the diagonal brace 21 relative to the first U-shaped steel 111, thereby enabling the overall adjustment and fixing of the tilt angle of the entire diagonal brace. To effectively prevent the adjusting screw 117 from loosening, a locking nut 118 is fitted onto each adjusting screw 117. After adjusting the tilt angle of the diagonal brace using the adjusting screw 117, the locking nut 118 is tightened to prevent the adjusting screw 117 from loosening.
[0028] In practical applications, the angle between the left end of the diagonal brace 21 and the corresponding first U-shaped steel 111 is F, and the angle between the right end of the diagonal brace 21 and the corresponding first U-shaped steel 111 is E. When E and F are equal, the support frames 11 at both ends of the diagonal brace 21 can be kept parallel to each other, thereby achieving a stable support for the diagonal brace.
[0029] In practical application, the entire utility model is placed on the building support platform 6. During the concrete pouring process, in order to effectively prevent the entire utility model from shifting on the building support platform 6, an auxiliary fixing rod 119 is fixedly installed on the upper part of the two first U-shaped steels 111 adjacent to the inclined high end of the diagonal brace. In practical application, after the utility model is placed at the designated position, the auxiliary fixing rod 119 is fixedly connected to the scaffolding using cross fasteners, thereby assisting in the fixation of the utility model.
[0030] Based on the above embodiments, the specific implementation of the baffle assembly is as follows: the baffle assembly further includes two vertical connecting rods 31. The two vertical connecting rods 31 in each baffle assembly are symmetrically arranged between the two diagonal braces 21. The baffle 32 is detachably disposed at the lower part of the corresponding two vertical connecting rods 31. The vertical connecting rods 31 can be adjusted, moved, and positioned along the length direction of the diagonal braces 21, and the vertical connecting rods 31 can be rotated and positioned relative to the diagonal braces 21. The specific implementation of the connection between the vertical connecting rods 31 and the diagonal braces 21 is as follows: two second elongated holes 214 corresponding to the corresponding vertical connecting rods 31 are provided on the diagonal braces 21. The two second elongated holes 214 are distributed along the length direction of the diagonal braces 21, and the two second elongated holes 214... The components 14 are arranged in a vertically opposite manner. A connecting bolt is fitted into each of the second elongated holes 214. The connecting bolts can move and rotate freely within the second elongated holes 214. The inner ends of two corresponding connecting bolts are fitted into the upper part of the corresponding vertical connecting rod 31. The two connecting bolts can rotate freely relative to the corresponding vertical connecting rod 31. To facilitate the smooth angle adjustment of the vertical connecting rod 31 relative to the diagonal brace 21, the width of the second elongated hole 214 is made slightly larger than the outer diameter of the connecting bolt. By tightening the nut on the connecting bolt, the vertical connecting rod 31 is fixed on the diagonal brace 21. After the diagonal brace 21 is fixed, the vertical placement adjustment of the vertical connecting rod 31 can be achieved by adjusting the position of the connecting bolt, and finally the vertical placement adjustment of the baffle 32 is achieved. Furthermore, by utilizing the design of the second elongated hole 214, the vertical connecting rod 31 can be moved and adjusted along the length direction of the diagonal brace 21, thereby enabling the adjustment of the horizontal width of the stair treads and improving the application flexibility of this utility model.
[0031] The baffle 32 and the vertical support rod 31 are fixedly connected by bolts, which facilitates the replacement of different models of baffles 32 at the bottom of the vertical support rod 31. In practical applications, to improve the lateral support strength of the baffles 32, a reinforcing plate 321 is fixedly installed on the left side of each baffle 32.
[0032] In practical applications, this utility model can be assembled in advance according to the design requirements of the staircase. During the formwork support process of the staircase, the utility model can be hoisted to the corresponding formwork support position and effectively fixed, which can facilitate the improvement of the formwork support efficiency of the staircase. When installing and fixing this utility model, the utility model is located between the inner formwork 4 and the outer formwork 5 on the building support platform 6. The bottom formwork, inner formwork 4, outer formwork 5 and several baffles 32 form the pouring space of the staircase. After the staircase is poured and formed, the utility model can be hoisted away as a whole, which can improve the demolding efficiency of the staircase.
[0033] In this utility model, "upper", "lower", "front", "back", "left", and "right" are all relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as limitations on the scope of protection.
