Description

Technical Field

[0001] The present invention relates to the technical field of UHPC cladding boards, and more particularly, to a UHPC cladding board forming process. Background Art

[0002] UHPC panels are building panels made of ultra-high performance concrete (UHPC). They feature high strength, high durability, lightweight, aesthetics, and environmental friendliness, demonstrating broad application prospects in high-end architecture, landscape design, public facilities, and other fields. To facilitate installation, sleeve connection blocks are formed during the molding process. These blocks contain pre-embedded sleeves, which are then quickly installed by bolting the sleeves to the supporting steel frame.

[0003] The existing UHPC cladding molding process uses a mold to integrally mold the sleeve connection block and the cladding body. Since the sleeve connection block protrudes from the surface of the cladding body, such a mold is difficult to manufacture, has high production costs, and is very inconvenient to cast, resulting in low production efficiency of UHPC cladding. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects in the prior art and provide a UHPC cladding forming process that is convenient and fast to form.

[0005] To achieve the above objectives, the technical solution of the present invention is to provide a UHPC panel forming process, wherein the UHPC panel includes a panel and a plurality of sleeve connecting blocks connected to the panel, wherein the plurality of sleeve connecting blocks are distributed in a linear array, and the forming process includes the following steps: S1. pouring UHPC slurry into a plurality of sleeve connection block molds to prefabricate a plurality of the sleeve connection blocks; S2, pre-installing a plurality of the sleeve connecting blocks on a positioning frame; S3, setting up the positioning frame above the panel mold; S4. Use a level to check and fine-tune the position and verticality of the sleeve connecting block; S5. Pouring UHPC slurry into the panel mold to form the panel, and combining the panel with the sleeve connecting block to form a UHPC hanging plate; S6, the panel is left to stand for curing; S7, UHPC hanging board lifting and demoulding; S8, removing the positioning frame; The sleeve connection block mold includes a bottom mold, the bottom mold is provided with a first mold cavity, the embedded sleeve is pre-installed in the first mold cavity by screws, one end of the embedded sleeve is attached to the wall of the first mold cavity, and the other end of the embedded sleeve extends outside the first mold cavity. The panel mold is provided with a second mold cavity.

[0006] By using the UHPC hanging plate forming process of the present invention, first, the sleeve connection block is prefabricated by the sleeve connection block mold, and then the panel and the sleeve connection block are combined to form the UHPC hanging plate during the casting and forming process of the panel. On the one hand, the sleeve connection mold and the panel mold are simpler in structure than the integral forming mold and are easy to manufacture, greatly reducing the production cost of the mold. On the other hand, it is very convenient to pour UHPC slurry into the first mold cavity and the second mold cavity, and the pouring situation of the slurry can be clearly observed, so as to facilitate filling and smoothing, greatly improving the production efficiency of the UHPC hanging plate.

[0007] Preferably, the bottom mold is provided with a supporting surface, the nut of the screw is located between the supporting surface and the first mold cavity, a grid is sleeved outside the embedded sleeve, and S1 includes the following steps: S11. Pass the screw through the mounting hole on the bottom mold so that the threaded section of the screw extends into the first mold cavity; S12. Lay the grid at the notch of the first mold cavity; S13. Pass the embedded sleeve through the mesh hole of the grid and thread it onto the screw; S14. Place the sleeve connection block mold on a horizontal plane so that the supporting surface is in contact with the horizontal plane; S15. Pour UHPC slurry into the first mold cavity; S16. The sleeve connection block is cured statically; S17. Remove the screw; S18. Take out the sleeve connection block from the first mold cavity.

[0008] With such a design, by setting the supporting surface, it is beneficial to place the sleeve connection block mold flat and ensure the casting quality of the sleeve connection block.

[0009] Preferably, in S15, the UHPC slurry covers part of the grid. The prefabricated sleeve connection block includes a connection block body, the embedded sleeve and the grid. A part of the embedded sleeve is built into the connection block body, and the grid is connected to the connection block body. With such a design, the middle part of the grid is combined with the connection block body, and the other parts of the grid are combined with the panel, which is beneficial to improving the bonding strength between the sleeve connection block and the panel and improving the crack resistance of the UHPC hanging plate.

[0010] Preferably, the main body of the connecting block is arranged in the shape of a regular frustum of a pyramid. The side length of the top surface of the main body of the connecting block is a, and the side length of the bottom surface of the main body of the connecting block is b. The value range of a is 50 mm - 200 mm, the value range of b is 70 mm - 250 mm, and b > a. In S5, the UHPC slurry submerges the bottom surface. Such a design is beneficial to avoiding stress concentration phenomena, thereby improving the durability of the UHPC hanging panel.

[0011] Preferably, the bonding depth between the main body of the connecting block and the panel is not less than 10 mm. Such a design can ensure that the bonding strength between the sleeve connecting block and the panel meets the design requirements.

[0012] Preferably, the embedded sleeve extends out of the bottom surface. The height of the main body of the connecting block is h, and the height of the embedded sleeve is l, and they satisfy the relational expression: l = h + 5. The value range of h is 20 mm - 40 mm. Such a design, during the process of the main body of the connecting block being combined with the panel, the fixing member and part of the sleeve main body will also be combined with the panel, which is beneficial to improving the connection strength and integrity between the sleeve connecting block and the panel.

[0013] Preferably, the distance between two adjacent sleeve connecting blocks is x, and the value range of x is 500 mm - 800 mm. Such a design, when any part of the UHPC hanging panel is subjected to an external force, the sleeve connecting blocks can effectively disperse the external force, ensuring the durability performance of the UHPC hanging panel.

[0014] Preferably, a plurality of angle code members distributed linearly in an array are detachably installed on the positioning frame through bolts and nuts, and the sleeve connecting block is pre-installed on the angle code members through pre-installed bolts. Such a design, when it is necessary to produce UHPC hanging panels of another size, the angle code members can be removed and installed on the required positioning frame to meet the distribution requirements of the sleeve connecting blocks, which is beneficial to reducing production costs.

[0015] Preferably, the sleeve connecting block mold is formed by welding and splicing multiple steel plates. Such a design is beneficial to the manufacturing of the sleeve connecting block mold and reduces the manufacturing cost of the sleeve connecting block mold.

[0016] Preferably, the material of the panel mold is set as wood or fiberglass. Such a design, using molds of different materials according to the required production quantity, is beneficial to reducing the production cost of the UHPC hanging panel.

[0017] The beneficial effects of the present invention are as follows: By using a UHPC wall panel forming process according to the present invention, a sleeve connection block is prefabricated through a sleeve connection block mold first, and then the panel and the sleeve connection block are combined to form a UHPC wall panel during the process of casting and forming the panel. On the one hand, compared with an integrally formed mold, the sleeve connection mold and the panel mold have a simpler structure and are easier to manufacture, greatly reducing the production cost of the mold. On the other hand, it is very convenient to pour UHPC slurry into the first mold cavity and the second mold cavity, and the pouring situation of the slurry can be clearly observed to facilitate filling and leveling, greatly improving the production efficiency of the UHPC wall panel.

Detailed implementation manners

[0020] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed so that those skilled in the art can better understand and thus implement the subject matter described herein. The functions and arrangements of the elements discussed can be changed without departing from the scope of protection of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0021] For a better understanding of the present invention, the following Figures 1-18 will be used to describe in detail a UHPC wall panel forming process of the present invention.

[0022] Example 1: As Figures 1-8 shown, a UHPC wall panel forming process, the UHPC wall panel includes a panel 100 and a plurality of sleeve connection blocks 200 connected to the panel 100, and the plurality of sleeve connection blocks 200 are distributed in a linear array. The forming process includes the following steps: S1. Pour UHPC slurry into a plurality of sleeve connection block molds 300 to precast a plurality of sleeve connection blocks 200; S2. Pre-install a plurality of sleeve connection blocks 200 on a positioning frame 400; S3. Place the positioning frame 400 above the panel mold 500; S4. Use a spirit level to recheck and fine-tune the position and verticality of the sleeve connection blocks 200; S5. Pour UHPC slurry into the panel mold 500 to form the panel 100, and the panel 100 is combined with the sleeve connection block 200 to form the UHPC hanging panel; S6. Let the panel 100 cure statically; S7. Lift and demold the UHPC hanging panel; S8. Remove the positioning frame 400; The sleeve connection block mold 300 includes a bottom mold 310. The bottom mold 310 is provided with a first mold groove 311. The embedded sleeve 210 is pre-installed in the first mold groove 311 through a screw 320. One end of the embedded sleeve 210 is attached to the groove wall of the first mold groove 311, and the other end of the embedded sleeve 210 extends outside the first mold groove 311. The panel mold 500 is provided with a second mold groove 510.

[0023] It should be noted that the bottom mold 310 is provided with an installation hole 312 communicating with the first mold groove 311. The embedded sleeve 210 is provided with a screw hole 211 threadedly matched with the screw 320. After the screw 320 passes through the installation hole 312, it is locked by the embedded sleeve 210 from the other side of the bottom mold 310, that is, the nut of the screw 320 and the embedded sleeve 210 are located on both sides of the bottom mold 310 respectively; In S5, before pouring the UHPC slurry, apply a release agent on the groove wall of the second mold groove 510. When pouring the UHPC slurry into the second mold groove 510, pour it from the middle to both sides of the second mold groove 510. The UHPC slurry has good fluidity and self-compacting property. After pouring, the UHPC slurry automatically levels by virtue of its self-compacting property and fills the gaps around the sleeve connection block 200.

[0024] By using the UHPC hanging panel forming process described in the present invention, the sleeve connection block 200 is prefabricated by the sleeve connection block mold 300 first, and then the panel 100 is combined with the sleeve connection block 200 to form the UHPC hanging panel during the casting process of the panel 100. On the one hand, compared with the integrally formed mold, the sleeve connection mold and the panel mold 500 have a simpler structure and are easier to manufacture, greatly reducing the production cost of the mold. On the other hand, it is very convenient to pour the UHPC slurry into the first mold groove 311 and the second mold groove 510, and the pouring situation of the slurry can be clearly observed, so as to facilitate filling and leveling, greatly improving the production efficiency of the UHPC hanging panel.

[0025] Example 2: As an optimization of Example 1, such as Figure 2 、 Figure 4 、 Figure 6 、 Figure 9 and Figure 10As shown, the bottom mold 310 is provided with a supporting surface 313. The nut of the screw 320 is located between the supporting surface 313 and the first mold groove 311. A grid 220 is sleeved outside the outer sleeve of the embedded sleeve 210. S1 includes the following steps: S11. Pass the screw 320 through the mounting hole 312 on the bottom mold 310 so that the threaded section of the screw 320 extends into the first mold groove 311. S12. Lay the grid 220 at the notch of the first mold groove 311. S13. Pass the embedded sleeve 210 through the mesh hole of the grid 220 and threadedly install it on the screw 320. S14. Place the sleeve connection block mold 300 on a horizontal plane so that the supporting surface 313 fits with the horizontal plane. S15. Pour UHPC slurry into the first mold groove 311. S16. Let the sleeve connection block 200 stand for curing. S17. Remove the screw 320. S18. Take out the sleeve connection block 200 from the first mold groove 311.

[0026] It should be noted that in S12, the four peripheral edges of the grid 220 are located outside the first mold groove 311, and the notch of the first mold groove 311 is aligned with the center of the grid 220; in S13, tighten the embedded sleeve 210 so that the embedded sleeve 210 fits tightly with the inner wall of the bottom mold 310 to prevent UHPC slurry from flowing into the screw hole 211 during the pouring of UHPC slurry and the subsequent standing curing process of the sleeve connection block 200, which affects the removal of the screw 320; in S14, after the sleeve connection block mold 300 is placed flat, the notch of the first mold groove 311 faces upward; in S15, before pouring UHPC slurry, apply a release agent on the groove wall of the first mold groove 311. By providing the supporting surface 313, it is beneficial to place the sleeve connection block mold 300 flat and ensure the pouring quality of the sleeve connection block 200.

[0027] Example 3: As an optimization of Example 2, as Figure 9 and Figure 10 shown, in S15, the UHPC slurry covers part of the grid 220. The prefabricated sleeve connection block 200 includes a connection block body 230, an embedded sleeve 210, and a grid 220. A part of the embedded sleeve 210 is built into the connection block body 230, and the grid 220 is connected to the connection block body 230.

[0028] It should be noted that the grid 220 can be set as a fiberglass grid or a metal grid. In S15, when pouring the UHPC slurry into the first die cavity 311, the UHPC slurry enters the first die cavity 311 through the pores of the grid 220. After pouring is completed, at least a part of the middle part of the grid 220 is combined with the connecting block body 230. During the pouring process of S5, the other parts of the grid 220 are combined with the panel 100. The grid 220 can increase the contact area between the sleeve connecting block 200 and the panel 100, thereby improving the bonding strength between the sleeve connecting block 200 and the panel 100. Moreover, the design of the grid 220 is beneficial to improving the crack resistance of the UHPC hanging panel, and further improving the quality of the UHPC hanging panel.

[0029] Embodiment 4: As an optimization of Embodiment 3, as Figures 15-18 shown, the grid 220 is set as a double-layer metal grid. The grid 220 includes a first-layer grid 221, a second-layer grid 222 connected to the first-layer grid 221, and connecting metal wires 223 that are simultaneously connected to the first-layer grid 221 and the second-layer grid 222. The geometric structures and dimensional parameters of the first-layer grid 221 and the second-layer grid 222 are exactly the same. The first-layer grid 221 and the second-layer grid 222 are arranged in parallel and overlap. The second-layer grid 222 is located on the side of the first-layer grid 221 away from the connecting block body 230. The connecting metal wires 223 are arranged perpendicular to the first-layer grid 221. The connecting metal wires 223 located on the side of the first-layer grid 221 away from the second-layer grid 222 are accommodated in the first die cavity 311, and the connecting metal wires 223 located on the side of the second-layer grid 222 away from the first-layer grid 221 are combined with the panel 100; In S18, after taking out the sleeve connecting block 200, a release slit 2221 is cut at the corner of the second grid 222 using a wire cutter, and then the second grid 222 between two adjacent release slits 2221 is bent away from the first-layer grid 221 using pliers. The included angle between the bent parts of the first-layer grid 221 and the second-layer grid 222 is preferably 1° - 10°.

[0030] It should be noted that the connecting metal wires 223 can be connected to the first-layer grid 221 and the second-layer grid 222 simultaneously by means of weaving or welding; the overlapping arrangement of the first-layer grid 221 and the second-layer grid 222 means that the orthographic projections of the first-layer grid 221 and the second-layer grid 222 on the bottom surface 232 of the connecting block body 230 completely coincide. The cutting direction of the release slit 2221 points from the corner of the second grid 222 to the connecting block body 230, and the cutting range of the release slit 2221 is the part where the second grid 222 exceeds the bottom surface 232 of the connecting block body 230; The connecting wire 223 is only distributed in the middle area of the first-layer grid 221 and the second-layer grid 222. After the connecting block body 230 is cast and formed, the middle part of the first-layer grid 221 is combined with the connecting block body 230. The middle part of the second-layer grid 222 can be combined with the connecting block body 230 or not. The connecting wire 223 extending into the first die cavity 311 is completely covered by the connecting block body 230. After the panel 100 is cast and formed, the connecting wire 223 on the side of the second-layer grid 222 away from the first-layer grid 221 is completely covered by the panel 100, and the bent part of the second grid 222 is also completely covered by the panel 100.

[0031] In this embodiment, the connecting wire 223 is welded to both the first-layer grid 221 and the second-layer grid 222, and the welding position is at the corresponding grid intersection. Both the first grid 221 and the second grid 222 are square. Four release slits 2221 are cut in the second grid 222, and the outer ring parts of the four sides of the second grid 222 are bent.

[0032] By setting the double-layer grid 230, the contact area between the grid 230 and the panel 100 can be increased, and the bonding strength between the sleeve connecting block 200 and the panel 100 can be further improved. By setting the connecting wire 223 perpendicular to the first-layer grid 221 and bending the outer ring of the second grid 222, it is beneficial to improve the connection strength between the sleeve connecting block 200 and the panel 100, thereby improving the quality and integrity of the UHPC wall panel.

[0033] Embodiment 5: As an optimization of Embodiment 3, as Figure 11 and Figure 12 shown, the connecting block body 230 is set as a regular square frustum. The side length of the top surface 231 of the connecting block body 230 is a, and the side length of the bottom surface 232 of the connecting block body 230 is b. The value range of a is 50 mm - 200 mm, and the value range of b is 70 mm - 250 mm, and b > a. In S5, the UHPC slurry submerges the bottom surface 232.

[0034] It should be noted that both the top surface 231 and the bottom surface 232 of the connecting block body 230 are square. When pouring UHPC slurry into the second die groove 510 of the panel mold 500, the UHPC slurry covers the bottom surface 232, that is, the larger end of the connecting block body 230 is combined with the panel 100. On the one hand, when the UHPC hanging panel is subjected to an external force, it is beneficial to reduce the stress per unit area. Combining with the uniform dispersion of stress by the inclined surface 233 of the connecting block body 230, the stress concentration phenomenon can be effectively avoided, thereby reducing the risk of cracking and damage of the UHPC hanging panel and improving the durability of the UHPC hanging panel. On the other hand, such a design increases the contact area between the connecting block body 230 and the panel 100, which is beneficial to improving the bonding strength between the sleeve connecting block 200 and the panel 100. The orifice of the screw hole 211 is located at the center of the top surface 231 of the connecting block body 230. The regular quadrangular frustum-shaped connecting block body 230 is also beneficial to the demolding of the sleeve connecting block 200.

[0035] Example 6: As an optimization of Example 5, as Figure 13 shown, the bonding depth between the connecting block body 230 and the panel 100 is not less than 10 mm.

[0036] It should be noted that if the bonding depth between the connecting block body 230 and the panel 100 is less than 10 mm, the bonding strength between the connecting block body 230 and the panel 100 is relatively low. When the UHPC hanging panel is subjected to an external force, fracture is likely to occur at the joint between the connecting block body 230 and the panel 100. By setting the bonding depth between the connecting block body 230 and the panel 100 to be not less than 10 mm, the bonding strength between the connecting block body 230 and the panel 100 can be improved, thereby ensuring that the bonding strength between the sleeve connecting block 200 and the panel 100 meets the design requirements.

[0037] Example 7: As an optimization of Example 6, as Figure 8 、[[ID=‘18]] Figure 12 and Figure 13 shown, the embedded sleeve 210 extends out of the bottom surface 232. The height of the connecting block body 230 is h, and the height of the embedded sleeve 210 is l, and the relationship: l = h + 5 is satisfied, and the value range of h is 20 mm - 40 mm.

[0038] It should be noted that the embedded sleeve 210 includes a sleeve body 212 and a fixing member 213. The end face of the sleeve body 212 away from the fixing member 213 is flush with the top surface 231 of the connecting block body 230. The fixing member 213 is located on the side of the bottom surface 232 away from the top surface 231, and the fixing member 213 protrudes from the outer surface of the sleeve body 212. By designing the height of the embedded sleeve 210 to be 5 mm higher than the height of the connecting block body 230, during the combination of the connecting block body 230 and the panel 100, the fixing member 213 and part of the sleeve body 212 will also be combined with the panel 100, which is beneficial to improving the connection strength and integrity between the sleeve connecting block 200 and the panel 100, thereby ensuring the reliability and stability of the installation of the UHPC hanging panel. In S13, the grid 220 is sleeved on the outer ring of the sleeve body 212, and the fixing member 213 can also play a limiting role to prevent the grid 220 from falling off before pouring UHPC slurry into the first die groove 311.

[0039] In this embodiment, the fixing member 213 is arranged as a flat plate with a cross-shaped structure. The flat plate is perpendicular to the axis of the sleeve body 212, and the orthographic projection of the sleeve body 212 on the flat plate is completely located within the flat plate. When the UHPC hanging panel is subjected to an external force, the cross-shaped flat plate is beneficial to dispersing stress and avoiding the UHPC hanging panel from breaking due to stress concentration.

[0040] Embodiment 8: As an optimization of Embodiment 7, as Figure 1 shown, the distance between two adjacent sleeve connecting blocks 200 is x, and the value range of x is 500 mm - 800 mm.

[0041] It should be noted that the distance between two adjacent sleeve connecting blocks 200 refers to the straight-line distance between the center lines of two adjacent sleeve connecting blocks 200. If the distance between two adjacent sleeve connecting blocks 200 is too small (less than 500 mm), then the UHPC hanging panel needs to be provided with more sleeve connecting blocks 200, increasing the production cost, but the improvement of the ability of the UHPC hanging panel to resist external forces is very weak, resulting in a reduction in the cost performance of the UHPC hanging panel. If the distance between two adjacent sleeve connecting blocks 200 is too large (greater than 800 mm), when the UHPC hanging panel is subjected to a large external force in the central area between two adjacent sleeve connecting blocks 200, the dispersion effect of these two sleeve connecting blocks 200 and the surrounding sleeve connecting blocks 200 on the large external force is limited, and the UHPC hanging panel is prone to break at the stress point. By setting the distance between two adjacent sleeve connecting blocks 200 to be 500 mm - 800 mm, when any part of the UHPC hanging panel is subjected to an external force, the sleeve connecting block 200 can effectively disperse the external force and ensure the durability of the UHPC hanging panel.

[0042] Embodiment 9: As an optimization of Embodiment 8, as Figure 3 and Figure 14 shown, a plurality of angle code members 440 distributed in a linear array are detachably mounted on the positioning frame 400 through bolts and nuts, and the sleeve connection block 200 is pre-mounted on the angle code member 440 through a pre-installed bolt 450.

[0043] It should be noted that the positioning frame 400 includes a cross frame 410, a longitudinal frame 420 and a support frame 430, and at least two of the cross frame 410, the longitudinal frame 420 and the support frame 430 are provided. All the cross frames 410 are arranged in parallel, all the longitudinal frames 420 are arranged in parallel, all the support frames 430 are arranged in parallel. The longitudinal frame 420 is detachably mounted between two adjacent cross frames 410 through bolts, and the support frame 430 is detachably mounted on the cross frame 410 through bolts and nuts. The support frame 430 is erected on an external support (not shown in the figure); After the positioning frame 400 is erected, the distances between the cross frame 410 and the longitudinal frame 420 and the edge of the panel mold 500 are measured respectively by a spirit level, and the position of the support frame 430 is finely adjusted until the position of the positioning frame 400 meets the requirements. At this time, the orthographic projection of the area where the sleeve connection block 200 is pre-mounted on the positioning frame 400 on the panel mold 500 is located at the center of the panel mold 500, that is, the positions of all the sleeve connection blocks 200 meet the requirements; the spirit level is placed on the cross frame 410 and the longitudinal frame 420 respectively, and it is judged whether the erection of the positioning frame 400 meets the requirements by observing the position of the bubble in the bubble tube. If the bubble is located in the center of the bubble tube whether the spirit level is placed on the cross frame 410 or the longitudinal frame 420, it means that the erection of the positioning frame 400 meets the requirements. Since the sleeve connection block 200 is pre-mounted on the positioning frame 400 through the pre-installed bolt 450, the perpendicularity of the sleeve connection block 200 meets the requirements. If the bubble is not located in the center of the bubble tube, fine adjustment is carried out by placing a gasket between the support frame 430 and the external support until the erection of the positioning frame 400 meets the requirements; In S8, all the pre-installed bolts 450 are unscrewed, and the positioning frame 400 can be removed from the UHPC hanging plate; When it is necessary to produce UHPC hanging plates of another size, the angle code members 440 can be removed and installed on the required positioning frame 400 to meet the distribution requirements of the sleeve connection blocks 200, without having to re-produce the angle code members 440, which is beneficial to reducing production costs.

[0044] Embodiment 10: As an optimization of Embodiment 9, the sleeve connection block mold 300 is formed by welding and splicing multiple steel plates.

[0045] It should be noted that the sleeve connection block mold 300 is formed by welding and splicing multiple steel plates. On the one hand, the sleeve connection block mold 300 can be reused multiple times, which is convenient for the batch production of the sleeve connection block 200. On the other hand, by controlling the thickness of the steel plates used to manufacture the sleeve connection block mold 300, the manufacturing cost of the sleeve connection block mold 300 can be effectively reduced.

[0046] In this embodiment, the material of the sleeve connection block mold 300 is Q235A carbon structural steel. Q235A carbon structural steel has good welding performance, which is beneficial to the manufacture of the sleeve connection block mold 300. Moreover, the price of Q235A carbon structural steel is relatively low, which is beneficial to reducing the production cost of the sleeve connection block mold 300.

[0047] Embodiment 11: As an optimization of Embodiment 10, the material of the panel mold 500 is set to wood or fiberglass.

[0048] It should be noted that when the production quantity of UHPC wall panels of the same size is small, the panel mold 500 uses a wooden mold to reduce the production cost of the panel mold 500. When the production quantity of UHPC wall panels of the same size is large, the panel mold 500 uses a fiberglass mold to facilitate the batch production of UHPC wall panels. Compared with steel molds, fiberglass molds are lighter in weight, which is beneficial to the handling of the panel mold 500. Moreover, the processing cost of fiberglass molds is lower, and they have good corrosion resistance and aging resistance, and the maintenance cost is also lower. Using molds of different materials according to the required production quantity is beneficial to reducing the production cost of UHPC wall panels.

[0049] The embodiments of the invention have been described above in conjunction with the accompanying drawings. However, this embodiment is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms without departing from the purpose of this embodiment and the scope protected by the claims, and all of them fall within the protection scope of this embodiment.
