Description

Technical Field

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

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] When assembling stairs, precast stair molds are used to cast the stairs. Precast stair molds are steel molds used in industrialized prefabricated buildings to cast precast stairs.

[0004] Existing prefabricated stair molds for building assembly often require different molds to be used depending on the number of steps, which is very inconvenient. Therefore, they do not meet the current needs. In response, we propose a new type of prefabricated stair mold for building assembly. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated mold for building assembly staircases, in order to solve the problems mentioned in the background art, such as the inconvenience caused by the need to use different molds for manufacturing staircases due to the different number of steps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated staircase mold for building assembly, comprising a base plate, a mold front end plate movably mounted on one side of the top of the base plate, multiple splicing molds movably connected to the surface of the mold front end plate, a mold rear end plate movably connected to the outer side of the last splicing mold, a front baffle movably mounted on the front side surface of the mold front end plate, a rear baffle movably mounted on the front side surface of the mold rear end plate, a splicing baffle with the same number of splicing molds movably mounted between the front baffle and the rear baffle, a side baffle movably mounted on the outer side of the mold front end plate and the front baffle, the side baffle being bolted to the mold front end plate and the front baffle, and the connection points between the mold rear end plate and the rear baffle being bolted.

[0007] Preferably, the mold rear end plate and one side surface of the top of the splicing mold are provided with mold top grooves, and L-shaped limiting pins are movably installed inside the mold top grooves. The mold front end plate and the other side surface of the splicing mold are provided with limiting grooves near the bottom, and the bottom ends of the L-shaped limiting pins are movably inserted into the limiting grooves.

[0008] Preferably, the inner surface of the mold top groove is provided with a spring groove, a triangular plate is slidably installed inside the spring groove, and multiple compression springs are movably installed between the triangular plate and the inside of the spring groove. The outer surface of the triangular plate is in contact with the surface of the L-shaped limit pin.

[0009] Preferably, connecting blocks are fixedly installed on the rear end plate of the mold and the rear side surface of the splicing mold, and connecting grooves are provided on the front end plate of the mold and the front side surface of the splicing mold. The connecting blocks are movably inserted into the interior of the connecting grooves. Connecting plates are fixedly installed on one side surface of the rear baffle and the splicing baffle, and the connecting plates are slidably inserted into the interior of the splicing baffle and the front baffle.

[0010] Preferably, mounting seats are fixedly installed on the top surfaces of the mold front end plate, mold rear end plate, splicing mold, front baffle, rear baffle, and splicing baffle. Connecting rods are hinged to the inner sides of the mounting seats located at the top of the mold front end plate, mold rear end plate, and splicing mold. Sliding grooves are provided on both sides of the end of the connecting rods. Limit buckles are slidably installed inside the sliding grooves. Compression springs are movably installed between the limit buckles and the inside of the sliding grooves. Inclined grooves are provided on the outer surface of the limit buckles. Connecting holes are provided on both sides of the mounting seats located on the top surfaces of the front baffle, rear baffle, and splicing baffle. The limit buckles are slidably inserted into the connecting holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the cooperation of splicing molds and splicing baffles, allows for the increase in the number of stair steps that can be cast by combining multiple splicing molds during use. This facilitates the casting of staircases with different numbers of steps. During installation, the connecting block of one splicing mold can be directly inserted into the connecting groove on the surface of another splicing mold. After the front plate, rear plate, and splicing mold of the mold are spliced ​​together, the splicing baffles, which are the same number as the splicing molds, can be spliced ​​together and connected to the front and rear baffles. This allows the front and rear baffles and splicing baffles to block the front plate, rear plate, and splicing mold of the mold, forming a cavity in the staircase. This avoids the situation where the front and rear baffles cannot seal the cavity due to too many splicing molds.

[0013] 2. This utility model utilizes the cooperation of an L-shaped limiting pin and a connecting block. When the splicing mold and splicing baffle are spliced ​​together and connected to the front and rear plates of the mold, as well as the front and rear baffles, the L-shaped limiting pin can be inserted into the top groove of the mold. When the bottom end of the L-shaped limiting pin enters the top groove of the mold, it will hit the inclined surface of the triangular plate, causing the triangular plate to retract into the spring groove. At this time, the L-shaped limiting pin continues to descend to the bottom position inside the top groove of the mold. When the L-shaped limiting pin is released, the triangular plate will be ejected from the spring groove by the elastic potential energy of the compressed spring, pushing the L-shaped limiting pin so that the bottom end of the L-shaped limiting pin is inserted into the limiting groove. This stabilizes the connection between the front and rear plates of the mold and the splicing mold, preventing separation between the front and rear plates of the mold and the splicing mold. When it is necessary to disassemble the splicing mold, the L-shaped limiting pin can be pulled outward and removed from the top groove of the mold to separate the splicing mold.

[0014] 3. This utility model, through the cooperation of connecting rods and limiting buckles, allows the connecting rods at the top of the mold front plate, mold rear plate, and splicing mold to be rotated after the L-shaped limiting pins are installed. This causes the connecting rods to rotate into the mounting seats at the top of the front baffle, rear baffle, and splicing baffle. At this time, the limiting buckles will be ejected by the elastic potential energy of the compression spring and locked into the connecting holes. This allows the mold front plate and front baffle, the mold rear plate and rear baffle, and each splicing mold and each splicing baffle to be connected and positioned with each other through the connecting rods, making the device more stable and preventing the appearance of connection gaps.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 This utility model provides an embodiment of a prefabricated staircase mold for building assembly, comprising a base plate 1, a mold front end plate 2 movably mounted on one side of the top of the base plate 1, a plurality of splicing molds 4 movably connected to the surface of the mold front end plate 2, a mold rear end plate 3 movably connected to the outer side of the last splicing mold 4, a front baffle 6 movably mounted on the front side of the mold front end plate 2, a rear baffle 7 movably mounted on the front side of the mold rear end plate 3, a splicing baffle 8 of the same number as the splicing molds 4 movably mounted between the front baffle 6 and the rear baffle 7, a side baffle 5 movably mounted on the outer side of the mold front end plate 2 and the front baffle 6, the side baffle 5 being bolted to the mold front end plate 2 and the front baffle 6, and the connection points between the mold rear end plate 3 and the rear baffle 7 being bolted.

[0022] By combining the splicing mold 4 and the splicing baffle 8, when the device is in use, multiple splicing molds 4 can be combined to increase the number of stair steps that the device can cast. This makes it easier to cast stairs with different numbers of steps. During installation, the connecting block 14 of one splicing mold 4 can be directly inserted into the connecting groove 15 on the surface of another splicing mold 4. After the front plate 2, the rear plate 3, and the splicing mold 4 are spliced ​​together, the splicing baffles 8, which are the same number as the splicing mold 4, can be spliced ​​together and connected to the front baffle 6 and the rear baffle 7. This allows the front baffle 6, the rear baffle 7, and the splicing baffle 8 to block the front plate 2, the rear plate 3, and the splicing mold 4, forming a cavity in the staircase. This avoids the situation where there are too many splicing molds 4, which would prevent the front baffle 6 and the rear baffle 7 from sealing the cavity.

[0023] The mold rear end plate 3 and the top surface of the splicing mold 4 are both provided with mold top grooves 10. L-shaped limit pins 11 are movably installed inside the mold top grooves 10. The mold front end plate 2 and the other side surface of the splicing mold 4 are both provided with limit grooves 20 near the bottom. The bottom ends of the L-shaped limit pins 11 are movably inserted into the limit grooves 20.

[0024] The inner surface of the mold top groove 10 is provided with spring grooves 17. Triangular plates 18 are slidably installed inside the spring grooves 17. Multiple compression springs 19 are movably installed between the triangular plates 18 and the inside of the spring grooves 17. The outer surface of the triangular plates 18 is in contact with the surface of the L-shaped limit pins 11.

[0025] With the cooperation of the L-shaped limiting pin 11 and the connecting block 14, after the splicing mold 4 and the splicing baffle 8 are spliced ​​together and connected to the front mold plate 2, the rear mold plate 3, the front baffle 6, and the rear baffle 7 respectively, the L-shaped limiting pin 11 can be inserted into the mold top groove 10. When the bottom end of the L-shaped limiting pin 11 enters the mold top groove 10, it will hit the inclined surface of the triangular plate 18, causing the triangular plate 18 to retract into the spring groove 17. At this time, the L-shaped limiting pin 11 continues to descend to the bottom position inside the mold top groove 10, and then it is released. The L-shaped limiting pin 11 and the triangular plate 18 are pushed out of the spring groove 17 by the elastic potential energy of the compression spring 19, so that the bottom end of the L-shaped limiting pin 11 is inserted into the limiting groove 20. This stabilizes the connection between the front plate 2 of the mold, the rear plate 3 of the mold, and the splicing mold 4, and prevents the separation of the front plate 2 of the mold, the rear plate 3 of the mold, and the splicing mold 4. When it is necessary to remove the splicing mold 4, the L-shaped limiting pin 11 can be pulled outward and removed from the top groove 10 of the mold to separate the splicing mold 4.

[0026] Connecting blocks 14 are fixedly installed on the rear surfaces of the mold rear end plate 3 and the splicing mold 4. Connecting grooves 15 are provided on the front surfaces of the mold front end plate 2 and the splicing mold 4. The connecting blocks 14 are movably inserted into the interior of the connecting grooves 15. Connecting plates 16 are fixedly installed on one side surface of the rear baffle 7 and the splicing baffle 8. The connecting plates 16 are slidably inserted into the interior of the splicing baffle 8 and the front baffle 6.

[0027] Mounting seats 12 are fixedly installed on the top surfaces of the front end plate 2, rear end plate 3, splicing mold 4, front baffle 6, rear baffle 7, and splicing baffle 8. Connecting rods 9 are hinged to the inner sides of the mounting seats 12 at the top of the front end plate 2, rear end plate 3, and splicing mold 4. Sliding grooves 21 are provided on both sides of the end of the connecting rods 9. Limit buckles 23 are slidably installed inside the sliding grooves 21. Compression springs 22 are movably installed between the limit buckles 23 and the sliding grooves 21. Inclined grooves are provided on the outer surface of the limit buckles 23. Connecting holes 13 are provided on both sides of the mounting seats 12 at the top surfaces of the front baffle 6, rear baffle 7, and splicing baffle 8. The limit buckles 23 are slidably inserted into the connecting holes 13.

[0028] With the cooperation of connecting rod 9 and limit buckle 23, after the L-shaped limit pin 11 is installed, the connecting rod 9 at the top of the mold front plate 2, mold rear plate 3 and splicing mold 4 can be rotated, so that the connecting rod 9 rotates into the mounting seat 12 at the top of the front baffle 6, rear baffle 7 and splicing baffle 8. At this time, the limit buckle 23 will be ejected by the elastic potential energy of the compression spring 22 and jam into the interior of the connecting hole 13, thereby connecting and positioning the mold front plate 2 and front baffle 6, the mold rear plate 3 and rear baffle 7, and each splicing mold 4 and each splicing baffle 8 through the connecting rod 9, making the device more stable and avoiding the appearance of connection gaps.

[0029] When using the precast staircase molds assembled in this building, multiple splicing molds 4 can be combined to increase the number of staircase steps that can be cast, thus facilitating the casting of staircases with different numbers of steps. During installation, the connecting block 14 of one splicing mold 4 can be directly inserted into the connecting groove 15 on the surface of another splicing mold 4. After the front plate 2, the rear plate 3, and the splicing mold 4 are spliced ​​together, the splicing baffles 8, which are the same number as the splicing molds 4, can be spliced ​​together and connected to the front baffle 6 and the rear baffle 7. This allows the front baffle 6, the rear baffle 7, and the splicing baffle 8 to block the front plate 2, the rear plate 3, and the splicing mold 4, forming a cavity in the staircase. This avoids the situation where there are too many splicing molds 4, which would prevent the front baffle 6 and the rear baffle 7 from sealing the cavity.

[0030] After the splicing mold 4 and the splicing baffle 8 are spliced ​​together and connected to the front mold plate 2, the rear mold plate 3, the front baffle 6, and the rear baffle 7 respectively, the L-shaped limiting pin 11 can be inserted into the mold top groove 10. When the bottom end of the L-shaped limiting pin 11 enters the mold top groove 10, it will hit the inclined surface of the triangular plate 18, causing the triangular plate 18 to retract into the spring groove 17. At this point, the L-shaped limiting pin 11 continues to descend to the bottom position inside the mold top groove 10. Then, the L-shaped limiting pin 11 is released. Angle plate 18 will be ejected from spring groove 17 by the elastic potential energy of compression spring 19, pushing L-shaped limit pin 11 so that the bottom end of L-shaped limit pin 11 is inserted into the interior of limit groove 20, thereby stabilizing the connection between mold front plate 2, mold rear plate 3 and splicing mold 4, and preventing the separation between mold front plate 2, mold rear plate 3 and splicing mold 4. When it is necessary to remove splicing mold 4, L-shaped limit pin 11 can be pried outward and pulled out from mold top groove 10 to separate splicing mold 4.

[0031] After the L-shaped limit pin 11 is installed, the connecting rod 9 at the top of the mold front plate 2, the mold rear plate 3, and the splicing mold 4 can be rotated to rotate the connecting rod 9 into the mounting seat 12 at the top of the front baffle 6, the rear baffle 7, and the splicing baffle 8. At this time, the limit buckle 23 will be ejected by the elastic potential energy of the compression spring 22 and will be inserted into the interior of the connecting hole 13. This will make the mold front plate 2 and the front baffle 6, the mold rear plate 3 and the rear baffle 7, and each splicing mold 4 and each splicing baffle 8 connected and positioned with each other through the connecting rod 9, making the device more stable and avoiding the appearance of connection gaps.

[0032] Then, precast stair material is poured into the cavity between the front mold plate 2, the rear mold plate 3, the splicing mold 4 and the front baffle 6, the rear baffle 7 and the splicing baffle 8 to form a stair shape and complete the precast stair.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
