Description

Technical Field

[0001] This utility model relates to the field of ribbed plate production technology, specifically to a ribbed hollow plate prefabrication device. Background Technology

[0002] Ribbed slabs are reinforced concrete slab structures formed by casting reinforced concrete. These structures are widely used in building construction, such as underground garages and industrial plants, and significantly improve construction efficiency. Currently, ribbed slabs are prefabricated using molds. The specific production process typically involves placing a steel mesh in the mold, pouring concrete into the mold, and then demolding the ribbed slab after the concrete has cured.

[0003] Existing ribbed steel plate molds typically include a base plate and four side plates surrounding the base plate. The transverse and longitudinal reinforcing bars in the steel mesh are supported in multiple grooves opened at the top of the four side plates. Because the reinforcing bars may be tilted, bent, or misaligned during the fabrication process, it is difficult for all the transverse and longitudinal reinforcing bars to fit into the corresponding grooves on the side plates when placing the mesh. Therefore, the width of the grooves on the side plates is usually larger than the diameter of the reinforcing bars. However, increasing the groove width can cause grout leakage during pouring.

[0004] In addition, when demolding the ribbed slab after casting, it is usually necessary to remove the two side plates on opposite sides before hooking the two sides of the ribbed slab and lifting it upward from the mold. However, since a certain length of transverse and longitudinal reinforcing bars are reserved around the ribbed slab, and the ends of the transverse and longitudinal reinforcing bars are bent at right angles towards the bottom plate, the bent reinforcing bars will affect the removal of the side plates, making it inconvenient to move the side plates during removal and greatly reducing the demolding efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned problems in the production process of ribbed slabs and to provide a ribbed hollow slab prefabrication device. This device can not only improve the leakage of grout during the pouring of ribbed slabs, but also eliminate the demolding work and improve the demolding efficiency of ribbed slabs.

[0006] This utility model is achieved through the following technical solution: This utility model provides a prefabrication device for ribbed hollow slabs, including a prefabrication mold and a tilting hoist. The prefabrication mold includes a bottom mold and four side molds surrounding the bottom mold. The top of each side mold has multiple grooves facing downwards, arranged according to the distribution of reinforcing bars. Each groove has a grout-blocking component fixedly installed, which includes a flexible block. The top of the flexible block has a slot for sealing and engaging with the reinforcing bars. The prefabrication mold has support rods on any two opposite side molds. The tilting hoist is rotatably connected to the two support rods to tilt the prefabrication mold around the axis of the support rods.

[0007] As a preferred embodiment of this utility model, the grout-blocking component further includes a housing adapted to the groove, the housing being fixed in the groove, and the flexible block being fixed inside the housing.

[0008] As a preferred embodiment of this utility model, the flexible block is made of elastic rubber material.

[0009] As a preferred embodiment of this utility model, the bottom mold has an upwardly protruding square boss at its center, and the edge of the square boss transitions to the bottom of the bottom mold through a slope.

[0010] As a preferred embodiment of this utility model, the bottom mold is provided with an annular protrusion, which is arranged around the inner wall of the side mold.

[0011] As a preferred embodiment of this utility model, a plurality of protrusions are provided at intervals along the length direction on the inner wall of the side mold, and the cross-section and longitudinal section of the protrusions are both in the shape of an isosceles trapezoid.

[0012] As a preferred embodiment of this utility model, the protrusion is made of hard rubber material and is fixedly connected to the inner wall of the side mold by bolts.

[0013] As a preferred embodiment of this utility model, the tilting lifting device includes a crossbar, a sliding rod, and a pull plate. There are two sliding rods in an inverted L-shape. The upper end of the sliding rod is slidably connected to the crossbar to adjust the distance between the two sliding rods. The lower end of the sliding rod is provided with a sleeve to fit onto the support rod of the precast mold. There are two pull plates in an X-shaped hinged arrangement. The lower ends of the two pull plates are hinged to the two sliding rods.

[0014] As a preferred embodiment of this utility model, a groove is provided on the crossbar along its length direction, the upper end of the sliding rod is slidably inserted into the groove, an ear plate is fixedly provided on the upper end of the sliding rod, and the lower end of the pull plate is hinged to the ear plate.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects: This invention improves grout leakage during the pouring of ribbed slabs by installing a grout-blocking component in the groove of the side mold. The component includes a flexible block with a downward-facing slot at the top. Due to the deformability of the flexible block, the reinforcing bars can enter the slot and form a sealed connection when the reinforcing mesh is placed, which can effectively improve grout leakage during the pouring of ribbed slabs. At the same time, since the precast mold is provided with support rods, the precast mold can be rotated around the axis of the support rods by using a flipping hoist to form a rotatable connection with the two support rods, thereby realizing the demolding of the ribbed slabs and eliminating the need for side mold disassembly, thus improving the demolding efficiency of the ribbed slabs.

[0028] Please refer to Figures 1 to 9 This application provides a prefabrication device for a ribbed hollow slab, comprising a prefabrication mold and a tilting hoist. The prefabrication mold includes a bottom mold 1 and side molds 2. There are four side molds 2 surrounding the bottom mold 1. The top of each side mold 2 has multiple grooves facing downwards. The grooves are arranged according to the distribution of the reinforcing bars. Each groove has a grout-blocking component 21 fixedly installed. The grout-blocking component 21 includes a flexible block 211. The top of the flexible block 211 has a slot 2111 facing downwards. The slot 2111 is used to form a sealing connection with the reinforcing bars. The prefabrication mold has support rods 3 on any two opposite side molds 2. The tilting hoist is used to form a rotatable connection with the two support rods 3 to tilt the prefabrication mold around the axis of the support rods 3.

[0029] In this application, four side molds 2 are fixed to the bottom mold 1, and the four side molds 2 form a square casting cavity. The four side molds 2 can be fixed to the bottom mold 1 by bolts or by welding. Alternatively, any two opposite side molds 2 can be welded to the bottom mold 1, while the other two side molds 2 are connected to the first two side molds 2 by bolts. In short, the bottom mold 1 and the four side molds 2 must form the required casting cavity.

[0030] The specific structure of the aforementioned side mold 2 may include a first plate, a second plate, and several stiffening plates. The first plate is fitted onto the bottom wall of the bottom mold 1, the second plate is vertically welded to the first plate, and several stiffening plates are welded between the first plate and the second plate, so that the first plate, the second plate, and the several stiffening plates form an integral structure. The side of the second plate facing away from the stiffening plates faces the casting cavity, and multiple grooves are opened on the top of the second plate.

[0031] The flexible block 211 has a downward-facing groove 2111 at its top, allowing it to deform flexibly. During the insertion of the reinforcing bar into the groove 2111, even if the bar slightly shifts position, it can still smoothly enter the groove 2111 through compression deformation against the sides of the groove, forming a sealed connection and preventing grout leakage. Preferably, the width of the groove 2111 is adapted to the outer diameter of the reinforcing bar, or slightly smaller, and a chamfer can be provided at the entrance of the groove 2111 to facilitate the entry of the reinforcing bar.

[0032] In this application, the two support rods 3 on the precast mold can be round rods, and the strength of the round rods must be sufficient to prevent bending deformation during use. The tilting hoist can be rotatably connected to the two support rods 3, thereby tilting the precast mold around the axis of the support rods 3. After tilting, the entire precast mold faces upward and the casting cavity faces downward. At this time, the precast mold can be knocked off by the weight of the rib plate.

[0033] This application provides a grout-blocking component 21 in the groove of the side mold 2. The grout-blocking component 21 includes a flexible block 211, and the top of the flexible block 211 has a downward-facing slot 2111. Since the flexible block 211 has a certain deformation capacity, when the steel mesh is placed, the steel bars can enter the slot 2111 and form a sealed connection, which can effectively improve the grout leakage during the pouring of the ribbed plate. At the same time, since the precast mold is provided with support rods 3, the precast mold can be rotated around the axis of the support rods 3 by using a flipping hoist to form a rotatable connection with the two support rods 3, thereby realizing the demolding of the ribbed plate, eliminating the need for disassembling the side mold 2, and improving the demolding efficiency of the ribbed plate.

[0034] According to some embodiments of this application, the grout-blocking component 21 further includes a housing 212 adapted to the groove, the housing 212 being fixed in the groove, and the flexible block 211 being fixed inside the housing 212. By providing a housing 212 adapted to the groove and fixing the flexible block 211 inside the housing 212, it is convenient to manufacture the grout-blocking component 21 separately, and at the same time, it can prevent the flexible block 211 from falling off during demolding.

[0035] According to some embodiments of this application, the housing 212 is made of metal, and the flexible block 211 is made of elastic rubber. The metal housing 212, after being embedded in the groove of the side mold 2, can be fixed in the groove by spot welding; the elastic rubber flexible block 211 not only has good flexibility, but can also be fixed inside the metal housing 212 by vulcanization bonding, thereby forming the entire grout-blocking component 21.

[0036] According to some embodiments of this application, the bottom mold 1 has an upwardly protruding square boss 11 at its center, and the edge of the square boss 11 transitions to the bottom of the bottom mold 1 via a slope. By providing the square boss 11, a cavity structure with a certain depth and area can be prefabricated on one side of the ribbed plate.

[0037] According to some embodiments of this application, the bottom mold 1 is provided with an annular protrusion 12, which is arranged around the inner wall of the side mold 2. By providing a square boss 11, the edges of the prefabricated ribbed plate can be made lower than the side of the ribbed plate, that is, a small step structure is formed on the edges of the side of the ribbed plate.

[0038] According to some embodiments of this application, a plurality of protrusions 22 are spaced apart along the length direction on the inner wall of the side mold 2, and the cross-section and longitudinal section of the protrusions 22 are both isosceles trapezoidal in shape. By setting a plurality of protrusions 22, a plurality of recessed structures can be formed around the precast ribbed plate, thereby enhancing the interlocking force with the cast-in-place concrete structure.

[0039] According to some embodiments of this application, the protrusion 22 is made of hard rubber material and is fixedly connected to the inner wall of the side mold 2 by bolts. Using hard rubber protrusion 22 results in low cost and light weight, and the bolted connection to the side mold 2 facilitates disassembly and replacement in case of damage during use.

[0040] According to some embodiments of this application, the tilting lifting device includes a crossbar 4, a sliding rod 5, and a pull plate 6. There are two sliding rods 5, which are inverted L-shaped. The upper end of the sliding rod 5 is slidably connected to the crossbar 4 to adjust the distance between the two sliding rods 5. The lower end of the sliding rod 5 is provided with a sleeve 51 to fit onto the support rod 3 of the precast mold. There are two pull plates 6, which are arranged in an X-shaped hinged configuration. The lower ends of the two pull plates 6 are hinged to the two sliding rods 5.

[0041] When in use, the two lifting ropes of the lifting equipment are connected to the upper ends of the two pull plates 6. Then, the entire tilting lifting device is moved to the precast mold. By adjusting the distance between the two sliding rods 5, the circular sleeve 51 at the lower end of the sliding rod 5 can be fitted onto the support rod 3 of the precast mold. In this way, the precast mold can be tilted around the axis of the support rod 3, thereby realizing the demolding of the ribbed plate, eliminating the need for disassembling the side mold 2, and improving the demolding efficiency of the ribbed plate. At the same time, since the distance between the two sliding rods 5 is adjustable, the tilting lifting device can also be used for precast molds of ribbed plates of different sizes.

[0042] According to some embodiments of this application, a groove is provided on the crossbar 4 along its length direction, the upper end of the sliding rod 5 is slidably inserted into the groove, an ear plate 52 is fixedly provided on the upper end of the sliding rod 5, and the lower end of the pull plate 6 is hinged to the ear plate 52.

[0043] In this application, a rectangular tube is used as the crossbar 4, and the inner hole of the rectangular tube is the sliding groove. The sliding rod 5 is made of two rectangular tubes welded into an L shape. The shorter section of the rectangular tube is slidably inserted into the inner hole of the crossbar 4, and the longer section of the rectangular tube is in the vertical direction. A circular sleeve 51 is welded to its lower end. The inner diameter of the sleeve 51 is adapted to the support rod 3 of the precast mold.

[0044] According to some embodiments of this application, a limiting groove 41 is formed along the length direction at the top of the crossbar 4 near both ends. The limiting groove 41 communicates with the sliding groove, and the ear plate 52 is located in the limiting groove 41 and fixedly connected to the top of the sliding rod 5. By designing the limiting groove 41 and the ear plate 52 structure, not only can the sliding rod 5 be prevented from falling off the crossbar 4, but the limit position of the sliding rod 5 can also be limited.

[0045] It should be noted that the aforementioned limiting groove 41 is located at the top of the crossbar 4, and is present at both ends of the crossbar 4. The ear plate 52 is located in the limiting groove 41 and is welded and fixed to the top of the sliding rod 5. To facilitate welding on both sides of the ear plate 52, the aforementioned limiting groove 41 can be made wider. After the ear plate 52 is welded and fixed to the sliding rod 5, the sliding rod 5 can only slide along the axis of the crossbar 4 and cannot completely detach from the crossbar 4. The sliding range of the sliding rod 5 is determined by the dimensions of the limiting groove 41 and the ear plate 52 in the axial direction of the crossbar 4.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
