Technical Field
[0001] The utility model relates to the technical field of UHPC board forming, and particularly relates to a rapid forming device for UHPC thermal insulation boards. Background Art
[0002] The UHPC board refers to an Ultra-High Performance Concrete board, also known as an ultra-high strength concrete board; it is a concrete material composed of specially proportioned cement, fine sand, fine aggregate and additives; the UHPC board has excellent mechanical properties, including high strength, high compressive strength, high tensile strength and high flexural strength, etc.
[0003] The UHPC thermal insulation board is made of UHPC (Ultra-High Performance Concrete) material, aiming to provide excellent thermal insulation performance and structural strength. At present, a single UHPC thermal insulation board is made one by one using a mold or a whole board is made and then cut. The production efficiency is low when using a single mold method; when making a UHPC board by making a whole board, it is difficult to evenly distribute the thermal insulation material and fibers therein, resulting in the quality of UHPC thermal insulation not being guaranteed. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a rapid forming device for UHPC thermal insulation boards to solve the problems of low production efficiency of UHPC thermal insulation boards and inability to guarantee the quality of UHPC thermal insulation boards.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A rapid forming device for UHPC thermal insulation boards includes a forming mold, a UHPC precast board, a fiber mesh, a push plate and a pushing mechanism. The push plate is located in the forming mold. The push plate and the forming mold form a UHPC board forming groove. The UHPC board forming groove is used for inserting paired and bonded UHPC precast boards, fiber meshes and porous thermal insulation boards. The fiber mesh is located between the UHPC precast boards. The porous thermal insulation board is located between the UHPC precast board and the fiber mesh. The UHPC board forming groove is used for containing UHPC concrete. The pushing mechanism is used to control the movement of the push plate in the forming mold to extrude the UHPC precast board, the fiber mesh and the porous thermal insulation board. A locking member for fixing the push plate on the forming mold is provided on the push plate.
[0006] Principle of this solution: First, place the push plate into the forming mold. The push plate and the forming mold form a UHPC plate forming groove. Then, the pushing mechanism is in close contact with the push plate, and UHPC concrete is injected into the UHPC plate forming groove to a preset depth position. Then, the paired bonded UHPC precast plates, the first perforated insulation board, the fiber mesh, and the second perforated insulation board are inserted into the UHPC plate forming groove in sequence. The outermost sides of both ends of the whole plate formed in the UHPC forming groove are paired bonded UHPC precast plates. Start the pushing mechanism to drive the push plate to move, and squeeze the UHPC precast plates, the perforated insulation boards, and the fiber mesh together. During the squeezing process, the UHPC concrete gradually rises to fill the gaps between the UHPC precast plates, the perforated insulation boards, and the fiber mesh, forming a UHPC whole plate. Level it at the top, and then use the locking parts to fix the push plate on the forming mold. After the UHPC concrete is formed, move the forming mold and the push plate for subsequent concrete curing. After the curing is completed, separate the paired bonded UHPC precast plates to form multiple single-piece UHPC insulation boards.
[0007] Advantages of this solution: Using UHPC precast plates as molds to form single-piece UHPC insulation boards can evenly distribute the fiber mesh and the insulation board in the UHPC insulation board whole plate, improving the quality of the UHPC insulation board; Using the bonded UHPC precast plates can form multiple UHPC insulation boards at one time. After the UHPC forming groove is formed and demolded, only by separating the bonded UHPC precast plates can single-piece UHPC insulation boards be obtained, improving the production speed and efficiency of UHPC plates; The UHPC insulation boards can be produced in a process flow, improving the production efficiency of UHPC insulation boards and the quality of UHPC insulation boards; By forming with UHPC precast plates, during subsequent curing and separation, the UHPC precast plates can protect the parts with lower internal strength, improving the quality and production qualification rate of UHPC insulation boards.
[0008] Preferably, the forming mold includes a fixed plate, a movable plate, and a bottom plate. The fixed plates are symmetrically fixed on the bottom plate. The movable plate is detachably connected to one end of the bottom plate. The movable plate is located between the fixed plates. The push plate, the movable plate, the bottom plate, and the fixed plates form a UHPC plate forming groove. When demolding the UHPC plate, the movable plate can be detached to facilitate demolding; Using the push plate, the movable plate, the bottom plate, and the fixed plates to form a UHPC plate forming groove, the pushing mechanism can conveniently control the movement of the push plate.
[0009] Preferably, the bottom plate is provided with grooves, and the bottom of the push plate is provided with bumps for sealing the grooves. By setting the grooves, the UHPC concrete can flow between each UHPC precast plate, and the UHPC concrete can fully fill and cover the gaps of the internal parts of the UHPC forming groove, improving the quality of the UHPC insulation board and the qualified rate of the finished product quality.
[0010] Preferably, the grooves are symmetrically arranged on the bottom plate. The symmetrical arrangement increases connectivity, enabling the UHPC concrete to flow faster and accelerating the forming speed of the UHPC whole plate.
[0011] Preferably, the holes on the porous heat insulation plates on both sides of the fiber mesh are arranged in a staggered manner. This staggered arrangement enables heat to be transferred to the heat insulation plates as much as possible, improving the heat insulation and thermal insulation effect of the UHPC heat insulation plate.
[0012] Preferably, the widths of both ends of the porous heat insulation plate are greater than the width of the middle part. In this way, when the UHPC precast plate, the porous heat insulation plate, and the fiber mesh are pressed together, there are gaps between the porous heat insulation plate and the fiber mesh and between the porous heat insulation plate and the UHPC precast plate. These gaps are used to fill the UHPC concrete, so that the UHPC concrete can connect the UHPC precast plate, the porous heat insulation plate, and the fiber mesh together, with a better mixing and bonding effect, improving the quality and strength of the UHPC heat insulation plate.
[0013] Preferably, the surface of the UHPC precast plate close to the fiber mesh is a rough surface. In this way, a part of the UHPC concrete can cover and fill the surface of the UHPC precast plate, enhancing the connection strength between the UHPC precast plate and the porous heat insulation plate.
[0014] Preferably, the pushing mechanism includes a push rod and a pushing cylinder that drives the push rod to move. The push rod is in close contact with the push plate, and the push rod is located at the center of the push plate.
[0015] Preferably, the number of fiber meshes between the porous heat insulation plates is at least 1. Multiple fiber meshes can be arranged according to actual needs to improve the strength of the UHPC heat insulation plate.
[0016] Preferably, the height of the porous heat insulation plate is less than the height of the UHPC precast plate. In this way, a part of the concrete can be filled at the top of the control heat insulation plate, improving the strength of the UHPC heat insulation plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a further detailed description through specific implementation manners:
[0023] The reference numerals in the accompanying drawings of the specification include: forming die 1, fixed plate 11, moving plate 12, UHPC precast plate 2, fiber mesh 3, push plate 4, groove 5, and porous heat preservation plate 6.
[0024] Embodiment:
[0025] A rapid forming device for UHPC heat preservation plates is basically as shown in the attached Figure 1 attachment Figure 2 attachment Figure 3 attachment Figure 4 attachment Figure 5 and the attached drawings, and includes a forming die 1, a UHPC precast frame, and a fiber mesh 3. The forming die 1 includes a fixed plate 11, a moving plate 12, and a bottom plate. The fixed plates 11 are symmetrically fixed on the bottom plate. The moving plate 12 is arranged at one end of the bottom plate and is located between the fixed plates 11. The moving plate 12 is detachably connected to the bottom plate, and specifically, a pin connection method can be adopted. When demolding the UHPC plate, the moving plate 12 can be detached to facilitate demolding. A locking handle is also provided on the fixed plate 11, and the locking handle is used to lock the moving plate 12 and the fixed plate 11.
[0026] Among them, the fixed plate 11 and the moving plate 12 have the same height, and the height of the UHPC precast plate 2 is less than the height of the fixed plate 11. The UHPC precast plate 2 will extrude the UHPC concrete in the forming die 1, which can avoid the situation of direct leakage of UHPC concrete from the forming die 1 and causing waste of raw materials.
[0027] It further includes a push plate 4. The push plate 4 is located at the end of the bottom plate away from the moving plate 12 and is located between the fixed plates 11. The push plate 4, the moving plate 12, the bottom plate, and the fixed plates 11 are hermetically formed to form a UHPC plate forming groove. The UHPC plate forming groove is used to insert the paired-bonded UHPC precast plates 2, fiber meshes 3, and porous heat preservation plates 6. Among them, the fiber mesh 3 is located between the UHPC precast plates 2, and the porous heat preservation plate 6 is located between the UHPC precast plates 2 and the fiber mesh 3. By moving the push plate 4, the UHPC precast plates 2, porous heat preservation plates 6, and fiber meshes 3 on the bottom plate are extruded to form a thicker whole plate.
[0028] In this embodiment, in order to facilitate subsequent demolding, a demolding agent is applied to the inner wall of the forming die 1 and the contact surface between the push block and the UHPC precast plate 2. The demolding agent adopts an existing demolding agent, and no detailed description is given here.
[0029] The bottom plate is provided with a groove 5, and the bottom of the push plate 4 is provided with a convex block for sealing the groove 5. By setting the groove 5, UHPC concrete can flow between each UHPC precast slab 2, so that the UHPC concrete can fully fill and cover the voids of the internal components of the UHPC forming groove, improving the quality of the UHPC insulation board and the qualified rate of the finished product quality.
[0030] The groove 5 is symmetrically arranged on the bottom plate. The symmetrical arrangement increases connectivity, enabling the UHPC concrete to flow faster and accelerating the forming speed of the UHPC whole board.
[0031] The holes on the porous insulation board 6 on both sides of the fiber mesh 3 are arranged in a staggered manner. This staggered arrangement enables heat to be transferred to the insulation board as much as possible, improving the heat insulation effect of the UHPC insulation board.
[0032] The width of both ends of the porous insulation board 6 is greater than the width of its middle part. In this way, when the UHPC precast slab 2, the porous insulation board 6, and the fiber mesh 3 are pressed together, there are gaps between the porous insulation board 6 and the fiber mesh 3 and between the porous insulation board 6 and the UHPC precast slab 2. These gaps are used to fill UHPC concrete, so that the UHPC concrete can connect the UHPC precast slab 2, the porous insulation board 6, and the fiber mesh 3 together, with a better mixed bonding effect, improving the quality and strength of the UHPC insulation board. The porous insulation board 6 is similar to an I-shaped structure.
[0033] The side of the UHPC precast slab 2 close to the fiber mesh 3 is a rough surface. In this way, the surface of the UHPC precast slab 2 can be covered and filled with part of the UHPC concrete, enhancing the connection strength between the UHPC precast slab 2 and the porous insulation board 6.
[0034] Among them, the number of fiber meshes 3 between the porous insulation boards 6 is at least 1. Multiple fiber meshes 3 can be arranged according to actual needs to improve the strength of the UHPC insulation board. The height of the porous insulation board 6 is less than the height of the UHPC precast slab 2. In this way, it is possible to control the top of the insulation board to be filled with part of the concrete, improving the strength of the UHPC insulation board. In this embodiment, the fiber mesh 3 is a mesh woven from steel fiber, glass fiber, or copolymer formaldehyde fiber.
[0035] Among them, the cross-sectional area of the fiber mesh 3 is smaller than the cross-sectional area of the UHPC precast slab 2.
[0036] The push plate 4 is provided with a locking member for fixing the push plate 4 on the forming mold 1. The locking member can specifically be a locking handle. By changing the position of the locking handle, it is convenient to fix the push plate 4 on the fixed plate 11. In this embodiment, after the push plate 4 presses the UHPC precast frame and the fiber mesh 3 and vibrates them densely, the push plate 4 is fixed on the fixed plate 11, and then the overall mold is moved for subsequent concrete curing. At this time, the next whole board is made in the next forming mold 1.
[0037] Among them, the axis of the push plate 4 coincides with the axis of the moving plate 12.
[0038] A number of positioning blocks are provided at the end of the push plate 4 far from the UHPC precast frame, and the positioning blocks are evenly distributed on the push plate 4. It is convenient to observe and control the moving direction of the push block through the positioning blocks. In this embodiment, 3 positioning blocks are provided on the push plate 4, and the 3 positioning blocks are respectively located on both sides and the middle of the push plate 4.
[0039] It further includes a pushing mechanism, the pushing mechanism includes a push rod and a pushing cylinder for driving the push rod to move, the push rod is in close contact with the push plate 4, and the push rod is located at the center of the push plate 4. It is convenient to control the movement of the push plate 4 through the pushing cylinder and the push rod. Specifically, the push rod is fixedly connected to the piston rod of the pushing cylinder by bolts. A rubber protective sleeve is provided on the contact surface between the push rod and the push plate 4, and the friction damage between the push rod and the push plate 4 is reduced through the rubber protective sleeve. When the pushing mechanism is started, the pushing mechanism causes the push plate 4 to squeeze the UHPC precast slab 2, the porous heat insulation board 6 and the fiber mesh 3 together, and the paired UHPC frames, the fiber mesh 3 inside them and the concrete form a single UHPC slab. After the UHPC precast frame and the fiber mesh 3 enter the UHPC slab forming groove, the UHPC concrete will be squeezed to its top. By extruding and forming the UHPC slab, the concrete moves from bottom to top, reducing air bubbles, making the inside of the UHPC slab more solid, and improving the quality of the UHPC slab.
[0040] A discharge port is provided on the forming die 1, and the discharge port is specifically arranged on the fixed plate 11. The discharge port is located at the end of the fixed plate 11 close to the moving plate 12 and above the UHPC precast frame. The UHPC concrete extruded from the UHPC precast frame and the fiber mesh 3 is directly discharged through the discharge port for utilization; the discharge port facilitates the collection of this part of the UHPC concrete. The discharge port is communicated with a discharge pipe to facilitate the collection of the UHPC concrete.
[0041] Specific implementation process: First, assemble the bottom plate, the moving plate 12, and the fixed plate 11 together. Then, place the push plate 4 on the bottom plate so that the push plate 4, the moving plate 12, the bottom plate, and the fixed plate 11 are airtight with each other to form a UHPC plate forming groove. Then, start the pushing cylinder and make the push rod in close contact with the push plate 4. After the assembly and positioning are completed, inject UHPC concrete at a preset depth position into the UHPC plate forming groove. Then, longitudinally and intermittently insert the pairwise-bonded UHPC prefabricated plates 2, the first perforated insulation board 6, the fiber mesh 3, and the second perforated insulation board 6 into the UHPC forming groove. Repeat the above process. At both outermost sides of the whole plate formed in the UHPC forming groove are pairwise-bonded UHPC prefabricated plates 2. After the UHPC prefabricated plates 2, the perforated insulation boards 6, and the fiber mesh 3 are inserted, the pushing cylinder and the push rod control the push plate 4 to move towards the moving plate 12, squeezing the UHPC prefabricated plates 2, the perforated insulation boards 6, and the fiber mesh 3 together. During the squeezing process, the UHPC concrete flows in the groove 5 and gradually rises to fill the gaps between the UHPC prefabricated plates 2, the perforated insulation boards 6, and the fiber mesh 3, forming a UHPC whole plate. Level it at the top, and then use the locking parts to fix the push plate 4 on the forming mold 1. After the UHPC concrete is formed, move the forming mold 1 and the push plate 4 for subsequent concrete curing. After the curing is completed, separate the pairwise-bonded UHPC prefabricated plates 2 to form multiple single-piece UHPC insulation boards.
[0042] This solution can produce UHPC insulation boards in a process flow, improving the production efficiency and quality of UHPC insulation boards; using the UHPC prefabricated plates 2 as molds to form single-piece UHPC insulation boards. After the UHPC forming groove is formed and demolded, the pairwise-bonded UHPC prefabricated plates 2 are separated to obtain single-piece UHPC insulation boards, improving the production speed and efficiency of UHPC insulation boards; forming with the UHPC prefabricated plates 2, during subsequent curing and separation, the UHPC prefabricated plates 2 can protect the parts with lower internal strength, improving the quality and production qualification rate of UHPC insulation boards; by setting the groove 5, the UHPC concrete can flow between each UHPC prefabricated plate 2, enabling the UHPC concrete to fully fill and cover the gaps of the internal parts of the UHPC forming groove, improving the quality and finished product qualification rate of UHPC insulation boards.
