Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated staircase modular mold. Background Technology

[0002] Precast stairs refer to stairs that are prefabricated in a factory using molds, and then transported to the construction site for assembly. The process of manufacturing precast stairs begins with binding the steel reinforcement frame. After binding, the frame is placed in a mold used for pouring concrete, and workers then pour concrete into the mold to complete the fabrication of the precast stairs.

[0003] Currently, the existing utility model with publication number CN213732400U discloses a horizontal precast staircase mold, including a mold and baffles. The mold consists of multiple bottom molds arranged in a stepped manner. The opposing sides of two adjacent bottom molds are slidably connected, and the structures on the multiple bottom molds are identical. There are two baffles arranged symmetrically, and the two baffles are located on one symmetrical side of the mold. Hollow blocks are welded to one symmetrical side of the bottom mold, and arc-shaped blocks are vertically slidably connected inside the hollow blocks. An opening adapted to the shape and size of the arc-shaped blocks is opened at the center of the top of the hollow blocks, and the top of the arc-shaped blocks passes through the opening. The same fourth spring is vertically welded between the bottom of the arc-shaped blocks and the bottom of the hollow blocks. Both baffles are provided with limiting mechanisms for limiting the arc-shaped blocks. There are multiple limiting mechanisms, and the opposing sides of the two baffles are provided with placing mechanisms for placing the mold. The lower bottom mold is provided with a moving mechanism for moving the upper bottom mold.

[0004] In the above-mentioned solution, after the concrete is poured into the mold in the existing technology, it needs to be compacted by workers using tools such as steel plates or wooden boards. Since one end of the precast staircase is usually higher than the horizontal plane, the concrete in the mold that is higher than the horizontal plane will collapse and sink under the action of gravity. In order to solve this problem, workers need to wait until the concrete is more viscous and then compact it again to ensure that the concrete that is higher than the horizontal plane will not collapse and sink. This results in a high labor intensity for the workers. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a prefabricated staircase split mold. By providing a first end template, an extrusion plate and a pressing component, it ensures that the concrete above the horizontal plane will not collapse or sink. This solves the problem that workers need to wait until the concrete is more viscous before compacting it again, thereby reducing the labor intensity of workers and ensuring that the quality of the prefabricated staircase is not affected.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A prefabricated staircase modular mold includes a frame, with a side template rotatably connected to the front and rear sides of the frame, a first end template rotatably connected to the left side of the frame, a support frame fixed to the upper end of the frame, a bottom template inserted into the upper end of the support frame, a second end template on one side of the bottom template, a single extrusion plate placed on the upper end of the two side templates, and multiple sets of fixing components on the upper end of the side templates, one of which has a pressing component.

[0008] When constructing a precast staircase, the side formwork is rotated to abut against the side walls of the frame and support, ensuring the side formwork is perpendicular to the frame. Simultaneously, the bottom formwork is inserted into the upper part of the support, with both sides of the bottom formwork abutting against the side walls of the side formwork. Multiple fixing components then secure the side formwork, tightly pressing it against the bottom formwork to fix it in the desired position. Concrete is poured into the cavity formed between the bottom formwork and the two side formworks, and then compacted using steel plates or wooden boards. An extrusion plate is placed on top of both side formworks, positioned close to the first formwork section. Next, the pressing component presses down on the extrusion plate to fix it in the required position. Then, the first end template is rotated to make it fit tightly with the two side templates and the bottom template. Bolts and other fasteners are then used to fix the first end template to ensure that the concrete above the horizontal plane will not collapse. The second end template is then placed on top of the two side templates and abutted against one side of the bottom template. Bolts and other fasteners are then used to fix the second end template to further shape the concrete and ensure that the quality of the precast staircase is not affected. After the concrete solidifies, the precast staircase is completed.

[0009] By incorporating a first end template, an extrusion plate, and a pressure-resistant component, the concrete above the horizontal level is prevented from collapsing or sinking. This solves the problem of existing technologies requiring workers to wait until the concrete becomes more viscous before compacting it again, thereby reducing the labor intensity of workers and ensuring that the quality of the precast stairs is not affected.

[0010] The utility model is further configured such that: the fixing component includes a first connecting plate fixed to the upper end of the side template, a second connecting plate fixed to the upper end of the bottom template, the first connecting plate and the second connecting plate having the same connecting rod inserted inside, a stop block fixed to one end of the connecting rod, and a nut screwed to the other end of the connecting rod.

[0011] With the above technical solution, when it is necessary to fix the two side templates and the bottom template, the connecting rod is inserted into the first connecting plate and the second connecting plate at the same time, and the stop block is pressed against the side wall of the second connecting plate. Then, the nut is rotated so that the nut is pressed against the side wall of the first connecting plate and the side template is pressed against the side wall of the bottom template, thereby fixing the two side templates and the bottom template.

[0012] The utility model is further configured such that: the pressing component includes a support block fixed on the side wall of the connecting rod, and a screw is screwed to the upper end of the support block, the screw passing through the pressing block at the extended end of the support block.

[0013] With the above technical solution, when it is necessary to fix the extrusion plate in the required position, the screw is rotated to drive the pressure block to move downward, so that the pressure block presses against the upper end of the extrusion plate, thereby fixing the extrusion plate in the required position.

[0014] The utility model is further configured such that a groove that mates with the bottom template is formed on the side wall of the side template.

[0015] With the above technical solution, when the bottom formwork abuts against the side wall of the side formwork, the bottom formwork is simultaneously inserted into the slot, thereby improving the sealing between the bottom formwork and the side formwork and ensuring that the concrete will not leak.

[0016] The utility model is further configured such that a positioning groove that mates with the bottom template is formed on the side wall of the second end template.

[0017] With the above technical solution, when a second end template needs to be placed, a positioning groove is provided, which makes it easy to place the second end template in the required position.

[0018] The utility model is further configured such that multiple reinforcing ribs are fixed to the upper end of the extrusion plate.

[0019] The above technical solution can improve the strength of the extruded plate and ensure that the extruded plate will not deform.

[0020] The beneficial effects of this utility model are:

[0021] Compared with existing technologies, by incorporating a first end template, an extrusion plate, and a pressure-resistant component, the concrete above the horizontal level is prevented from collapsing or sinking. This solves the problem that existing technologies require workers to wait until the concrete becomes more viscous before compacting it again, thereby reducing the labor intensity of workers and ensuring that the quality of the precast stairs is not affected.

[0022] The presence of slots improves the sealing between the bottom and side templates.

[0023] The positioning groove facilitates the placement of the second end template in the desired position.

[0024] The strength of the extruded plate can be improved by incorporating reinforcing ribs. Attached Figure Description

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] The following is for reference Figures 1 to 2 This utility model will now be described.

[0030] A prefabricated staircase modular mold includes a frame 1, with a side template 2 rotatably connected to the front and rear sides of the frame 1, a first end template 3 rotatably connected to the left side of the frame 1, a support frame 4 fixed to the upper end of the frame 1, a bottom template 5 inserted into the upper end of the support frame 4, a second end template 6 provided on one side of the bottom template 5, a single extrusion plate 7 placed on the upper end of the two side templates 2, and multiple sets of fixing components provided on the upper end of the side templates 2, one of which has a pressing component.

[0031] When constructing a precast staircase, the side formwork 2 is rotated to abut against the side walls of the frame 1 and support frame 4, and is positioned perpendicular to the frame 1. Simultaneously, the bottom formwork 5 is inserted and placed on the upper end of the support frame 4, with both sides of the bottom formwork 5 abutting against the side walls of the side formwork 2. Multiple sets of fixing components are then used to secure the side formwork 2, tightly pressing the bottom formwork 5 to fix it in the desired position. Concrete is poured into the cavity formed between the bottom formwork 5 and the two side formwork 2, and then compacted by workers using steel plates or wooden boards. An extrusion plate 7 is placed on top of both side formwork 2, positioned close to the first end of the formwork. Plate 3 is set, and then the pressing component presses the extrusion plate 7 to fix the extrusion plate 7 in the required position. Then, the first end template 3 is rotated so that the first end template 3 is tightly attached to the two side templates 2 and the bottom template 5. Then, bolts and other fasteners are used to fix the first end template 3 to ensure that the concrete above the horizontal plane will not collapse. Then, the second end template 6 is placed on the upper end of the two side templates 2 and abuts against one side of the bottom template 5. Bolts and other fasteners are used to fix the second end template 6 to further shape the concrete and ensure that the quality of the precast staircase is not affected. After the concrete solidifies, the precast staircase is completed.

[0032] By incorporating a first end template 3, an extrusion plate 7, and a pressure-resistant component, the concrete above the horizontal level is prevented from collapsing or sinking. This solves the problem of existing technologies requiring workers to wait until the concrete becomes more viscous before compacting it again, thereby reducing the labor intensity of workers and ensuring that the quality of the precast stairs is not affected.

[0033] The fixing assembly includes a first connecting plate 8 fixed to the upper end of the side template 2, a second connecting plate 9 fixed to the upper end of the bottom template 5, and the same connecting rod 10 inserted into the first connecting plate 8 and the second connecting plate 9. A stop block 11 is fixed to one end of the connecting rod 10, and a nut 12 is screwed to the other end of the connecting rod 10.

[0034] When it is necessary to fix the two side templates 2 and the bottom template 5, insert the connecting rod 10 into the first connecting plate 8 and the second connecting plate 9 at the same time, and make the stop block 11 abut against the side wall of the second connecting plate 9. Then rotate the nut 12 so that the nut 12 presses against the side wall of the first connecting plate 8 and the side template 2 presses against the side wall of the bottom template 5, thereby fixing the two side templates 2 and the bottom template 5.

[0035] The pressing assembly includes a support block 13 fixed to the side wall of the connecting rod 10, and a screw rod 14 screwed to the upper end of the support block 13. The screw rod 14 passes through the pressing block 15 on the extended end of the support block 13.

[0036] When it is necessary to fix the extrusion plate 7 in the desired position, rotate the screw 14 to drive the pressing block 15 to move downward, so that the pressing block 15 presses against the upper end of the extrusion plate 7, thereby fixing the extrusion plate 7 in the desired position.

[0037] The side wall of the side template 2 is formed with a groove 201 that matches the bottom template 5.

[0038] When the bottom formwork 5 abuts against the side wall of the side formwork 2, the bottom formwork 5 is simultaneously inserted into the slot 201, thereby improving the sealing between the bottom formwork 5 and the side formwork 2 and ensuring that the concrete will not leak.

[0039] The second end template 6 has a positioning groove 601 formed on its side wall to mate with the bottom template 5.

[0040] When it is necessary to place the second end template 6, the positioning groove 601 is provided to facilitate the placement of the second end template 6 in the required position.

[0041] Multiple reinforcing ribs 16 are fixed to the upper end of the extrusion plate 7.

[0042] This can improve the strength of the extrusion plate 7 and ensure that the extrusion plate 7 will not deform.

[0043] Working principle:

[0044] When constructing a precast staircase, the side formwork 2 is rotated to abut against the side walls of the frame 1 and support frame 4, ensuring that the side formwork 2 is perpendicular to the frame 1. Simultaneously, the bottom formwork 5 is inserted and placed on the upper end of the support frame 4, with both sides of the bottom formwork 5 abutting against the side walls of the side formwork 2. The connecting rod 10 is simultaneously inserted into the first connecting plate 8 and the second connecting plate 9, with the stop block 11 abutting against the side wall of the second connecting plate 9. Then, the nut 12 is rotated, pressing against the side wall of the first connecting plate 8, and pressing the side formwork 2 against the side wall of the bottom formwork 5. This fixes the two side formwork 2 pieces and tightly compresses the bottom formwork 5, thus fixing the bottom formwork 5 in the desired position. Concrete is poured into the cavity formed between the bottom formwork 5 and the two side formwork 2 pieces, and then compacted by workers using steel plates or wooden boards. The extrusion plate 7 is placed on the upper ends of the two side templates 2 and positioned close to the first end template 3. Then, the screw 14 is rotated to move the pressure block 15 downward, so that the pressure block 15 presses against the upper end of the extrusion plate 7, thereby fixing the extrusion plate 7 in the required position. Then, the first end template 3 is rotated so that the first end template 3 is tightly fitted together with the two side templates 2 and the bottom template 5. The first end template 3 is then fixed with bolts and other fasteners to ensure that the concrete above the horizontal plane will not collapse. The second end template 6 is then placed on the upper ends of the two side templates 2 and pressed against one side of the bottom template 5. The second end template 6 is then fixed with bolts and other fasteners to further shape the concrete and ensure that the quality of the precast staircase is not affected. After the concrete solidifies, the precast staircase is completed.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
