Description

Technical Field

[0001] The present invention relates to the technical field of engineering construction, and particularly relates to a UHPC pier cap thin-wall construction device suitable for convenient on-site production. Background Art

[0002] Pier cap construction is a common process in bridge construction. With the development of technology, the advantages of UHPC concrete have gradually emerged. As a new type of concrete material, UHPC concrete has the characteristics of high strength, high durability, high toughness, good wear resistance and corrosion resistance. In bridge construction, the pier cap is an important structural part connecting the pier and the bridge deck, bearing the load of the bridge and transmitting it to the pier. The advantages of using UHPC to make pier caps are as follows: High strength: Due to the extremely high strength of UHPC, the size and weight of the pier cap can be greatly reduced, thereby reducing the material consumption and construction difficulty. High durability: UHPC has excellent durability and can resist corrosion and wear under harsh environmental conditions, extending the service life of the bridge. Good seismic performance: UHPC has high toughness and ductility, can absorb and disperse seismic energy, and improve the seismic performance of the bridge. Therefore, UHPC pier caps have broad application prospects in bridge construction, especially in occasions requiring high performance, long life and high safety, such as long-span bridges, bridges on important traffic lines, etc. At present, conventional concrete pier cap structures are mostly constructed by cast-in-place or precast methods. However, cast-in-place concrete pier caps have problems such as large land occupation, long construction period and high safety risks, while precast concrete pier caps have problems such as large self-weight, inconvenient hoisting and transportation, poor overall mechanical properties and impermeability. Therefore, a rapid construction device for the thin-wall shell of a UHPC pier cap is proposed, which uses a precast UHPC thin-wall shell as the external formwork of the pier cap, and realizes the rapid lightweight construction of the pier cap by arranging a small amount of steel bars and filling core ordinary concrete inside the shell.

Specific implementation manner

[0017] As Figures 1-3 In [the figure], a UHPC capping beam thin-wall construction device suitable for on-site convenient production includes at least three coaxially arranged load-bearing plates 1. A lateral support assembly 2 is detachably provided on the upper part of the load-bearing plate 1. An end support assembly 9 is provided at the end of the lateral support assembly 2. The load-bearing plate 1, the lateral support assembly 2 and the end support assembly 9 cooperate to form a sealed cavity with an open top. A bottom die assembly 3 is provided on the middle load-bearing plate 1. Inner support assemblies 4 and steam generators are respectively provided on the two side load-bearing plates 1. An inner die 5 is detachably provided on the outer side of the inner support assembly 4. The inner support assembly 4 can move between different load-bearing plates 1. The load-bearing plate 1, the lateral support assembly 2, the bottom die assembly 3, the inner support assembly 4, the inner die 5 and the end support assembly 9 cooperate to form a thin-walled shell 6.

[0018] By using the load-bearing plate 1 and the mobile trolley 8 as modular components respectively, a bearing foundation is provided for the bottom die assembly 3, the inner support assembly 4 and the steam generator. During production, as Figures 1-3 shown in [the figure], according to the production sequence and rhythm, as Figure 6On the load-bearing plate 1 on one side, the inner mold 5 is first installed outside the inner support assembly 4, and then the assembled whole is moved to the upper side of the bottom mold assembly 3 and positioned and locked. UHPC concrete meeting the design capacity is poured in the sealed cavity. Through the cooperation of the load-bearing plate 1 and the inner support assembly 4, the process of drawing casting production is completed, thus realizing the production of the thin-walled shell 6. The inner mold 5 serves as a rigid support structure inside the thin-walled shell 6. After sufficient solidification, the inner support assembly 4 drives the inner mold 5 and the shaped thin-walled shell 6 into the steam curing device, as Figures 7-8 shown in, the inner support assembly 4 and the inner mold 5 are disassembled, and then the inner support assembly 4 is removed. Furthermore, the steam curing device is opened, and a cover plate is placed on the upper part of the sealed cavity at this position to complete the overall steam curing. To avoid occupying the site, when the inner support assembly 4 drives the inner mold 5 and the shaped thin-walled shell 6 into the steam curing device, its moving process is as Figures 4-5 shown in. The inner support assembly 4 is lifted, and then the load-bearing plate 1 and the moving trolley that are steam-curing the thin-walled shell 6 are moved to other positions to avoid occupying the production area for a long time. At this time, another sealed cavity connected to the steam curing device is used as a relay, as Figures 9-10 shown in. After the lifted inner support assembly 4 is lowered into this sealed cavity, the inner mold 5 is reinstalled, and then the support assembly 4 is lowered to the upper side of the bottom mold assembly 3 again, ensuring continuous production. At the same time, to further improve the overall production efficiency, two sets of the bottom mold assembly 3 and the inner support assembly 4 are provided. After the inner mold 5 is installed outside the inner support assembly 4, production can be carried out in cooperation with the bottom mold assembly 3. At this time, there are also two sets of steam curing devices, that is, two bottom mold assemblies 3 and inner support assemblies 4 cooperate with each other and serve as backups for each other. The inner mold 5 can be moved and adjusted between the two bottom molds 3, reducing the downtime due to faults and effectively ensuring the production efficiency.

[0019] As Figures 11-18 shown in, in a preferred solution, the lateral support assembly 2 includes two flap plates 201 arranged oppositely. The flap plates 201 are hinged to the load-bearing plate 1. The end support assembly 9 includes two end molds 901 arranged oppositely. The end molds 901 are slidably connected to the flap plates 201. An arc-shaped chute 203 is provided at the top of the flap plate 201. The inner support assembly 4 is slidably connected to the arc-shaped chute 203. During production, the sealed cavity can be adjusted by controlling the inner support assembly 2 and the end support assembly 9, facilitating the installation of other components. At the same time, the end mold 901 and the flap plate 201 are kept in a fitting state, so the problem of inconsistent sealing performance that may be caused by frequently opening and closing the end support assembly 9 can be avoided. The flap plate 201 can not only provide guidance for the inner support assembly 4 but also provide stable support, thus ensuring the convenience of moving and adjusting the inner support assembly 4.

[0020] In a preferred embodiment, two first supports 101 and two second supports 102 are symmetrically arranged on both sides of the bottom die assembly 3 on the load-bearing plate 1. Two first connectors 202 and two second connectors 206 are symmetrically arranged on both sides of the flap 201. The second connector 206 is connected to the second support 102 through the first telescopic cylinder 10. Both sides of the first telescopic cylinder 10 are hinged to the second connector 206 and the second support 102 respectively. The first support 101 is hinged to the first connector 202. With this structure, the flap 201 can be opened and closed conveniently. By the telescopic action of the first telescopic cylinder 10, the opening and closing angle of the flap 201 can be changed, which is convenient to use and has high operation efficiency.

[0021] As Figures 19-23 In [reference], in a preferred embodiment, a plurality of guide rods 204 are arranged in parallel on the outer side of the flap 201. A straight extension plate 902 is arranged on the outer side of the end die 901. A plurality of ear plates 903 are arranged in parallel on the straight extension plate 902. Through holes 904 are arranged through the ear plates 903. The guide rods 204 are inserted into the through holes 904. Nuts 205 are arranged on the outer sides of the guide rods 204. The flap 201 is connected to the straight extension plate 902 through the second telescopic cylinder 11 and the driving plate 12. Both sides of the driving plate 12 are fixed to the second telescopic cylinder 11 and the straight extension plate 902 respectively. A plurality of sealing grooves 905 and sealing strips 906 are also arranged on the inner side of the end die 901. When the two end dies 901 on both sides cooperate with each other, the opposite sealing strips 906 and sealing grooves 905 are inserted and connected, thereby greatly increasing the contact area between the two end dies 901 and ensuring the overall sealing efficiency. The flap 201 provides a stable moving platform for the end die 901 through the guide rods 204. By controlling variables, the requirements for adjustment during production are reduced, thereby ensuring the stability of production quality.

[0022] In a preferred embodiment, a moving trolley 8 is supported at the bottom of the load-bearing plate 1. Convex blocks 103 and concave blocks 104 are arranged on both sides of the load-bearing plate 1 respectively. Insertion plates 105 and through grooves 106 are symmetrically arranged on both sides of the thickness centers of the convex blocks 103 and the concave blocks 104 respectively. Alignment holes 107 are arranged through the insertion plates 105 and the through grooves 106. The insertion rods 18 are inserted into a plurality of alignment holes 107. The convex block 103 adopts a V-shaped structure, so that when two adjacent load-bearing plates 1 are connected, it plays a role in accurate alignment and installation accuracy, and is convenient for installation and disassembly at any time according to needs. The operation is convenient, and the overall locking can be completed without external tools.

[0023] As Figures 24-25Among them, in the preferred solution, multiple cross braces 401 are provided at the top of the inner support assembly 4. A pick plate 403 is connected to the lower side of the cross brace 401 by screws 14. Second waist-shaped grooves 402 and threaded holes 404 are respectively provided on the cross brace 401 and the pick plate 403. The screws 14 are arranged in the second waist-shaped grooves 402 and the threaded holes 404. Multiple balls 405 are provided at the bottom of the pick plate 403. The balls 405 are slidably arranged in the arc-shaped chute 203. Two third supports 108 are symmetrically provided on both sides of the upper part of the load-bearing plate 1. The third supports 108 are connected to the cross brace 401 through the third telescopic cylinder 13. With this structure, the cross brace 401 serves as the overall force-bearing part and at the same time as a transfer structure, providing a stable installation foundation for the pick plate 403. When the opening angle of the flap 201 is different, the position of the pick plate 403 relative to the cross brace 401 is different. When moving the inner support assembly 4 to the next step, the balls 405 roll in the arc-shaped chute 203, with small rolling friction, stable support, and smooth and efficient movement. After moving in place, the inner support assembly 4 is lifted, and then the pick plate 403 is moved outward to completely avoid contact with the flap 201. At this time, the cross brace 401 completely falls on the top of the flap 201, with convenient overall adjustment and stable operation.

[0024] In the preferred solution, a first C-shaped clamping plate 1301 and a second C-shaped clamping plate 1302 are provided at the top of the third telescopic cylinder 13. The first C-shaped clamping plate 1301 and the second C-shaped clamping plate 1302 are connected by screws 14. The first C-shaped clamping plate 1301 and the second C-shaped clamping plate 1302 cooperate to form a channel for clamping the cross brace 401. The inner sides of the first C-shaped clamping plate 1301 and the second C-shaped clamping plate 1302 are respectively attached to the bottom surface and the top surface of the cross brace 401; Such as Figure 3 Among them, after the third telescopic cylinder 13 is lifted in place and contacts the bottom of the cross brace 401, the second C-shaped clamping plate 1302 locks the first C-shaped clamping plate 1301, thereby ensuring the rapid lifting of the inner support assembly 4 and completing the height adjustment of the inner support assembly 4. At the same time, the third telescopic cylinder 13 mainly undertakes the adjustment within a lower height range, while the fourth telescopic cylinder 16 undertakes the adjustment within a higher height range. The third telescopic cylinder 13 and the fourth telescopic cylinder 16 play a role of mutual relay. Thus, when steam curing is required after the production of the thin-walled shell 6, the inner support assembly 4 is taken out from the thin-walled shell 6. The inner mold 5 is a part of the thin-walled shell 6, ensuring the overall structural strength. During production, only the production of the appropriate number of inner molds 5 needs to be completed according to requirements, making it more flexible and convenient to use; The flap 201 and the load-bearing plate 1 are also detachably provided with fixed pulleys 19. A winch 20 is provided on one side of the load-bearing plate 1 close to the fixed pulley 19. A pull ring 406 is provided at the end of the pick plate 403. The winch 20 is connected to the pull ring 406 through a pull rope. The pull rope is wound around the fixed pulley 19.

[0025] The hoist 20 can apply an axial force to the inner support assembly 4 preferably, thereby changing the position of the inner support assembly 4. When it is necessary to move the inner support assembly 4 to the next sealing cavity for processing, the end support assembly 9 is opened. At this time, on the premise of ensuring that the height of the support assembly 4 is slightly lifted, the outer pick plate 403 is moved towards the center side of the inner support assembly 4 to ensure that the position of the ball 405 meets the position of the arc chute 203, and the adjacent two flap plates 201 are kept in a coincident state, thus avoiding the problem of jamming during movement. After the ball 405 can fit into the arc chute 203, the lower inner support assembly 4 is adjusted, and at the same time, the bottom die assembly 3 is adjusted to change the angle of the movable plate 302 relative to the bearing plate 301 to ensure that the whole is in a horizontal state, which is convenient for the removal of the inner support assembly 4.

[0026] As Figures 26-28 In the figure, in the preferred solution, the bottom die assembly 3 includes a bottom plate 303 and a bearing block 301 arranged in the middle of the bottom plate 303. The two sides of the bearing block 301 are respectively hinged to the movable plate 302 through the shaft rods 308. A plurality of fifth telescopic cylinders 304 are also arranged on both sides of the bottom plate 303, and the tops of the fifth telescopic cylinders 304 are hinged to the movable plate 302. A plurality of pads 7 and cover plates for supporting the thin-walled shell 6 are arranged in the sealing cavity connected to the steam generator. Two ear plates 305 are symmetrically arranged at the lower part of the movable plate 302. A first waist-shaped groove 307 is penetrated through the ear plates 305. A driving head 306 is arranged at the top of the fifth telescopic cylinder 304, and the shaft rod 308 is arranged in the driving head 306 and the first waist-shaped groove 307. With this structure, the angle between the movable plate 302 and the bearing plate 301 can be adjusted according to needs to meet the changing needs of the angle during the production process, and at the same time, the error in the production of the inner mold can be corrected to ensure the controllability of the production quality of the thin-walled shell 6.

[0027] In the preferred solution, an auxiliary support assembly 15 is also detachably arranged on the outer side of the bearing plate 1. The auxiliary support assembly 15 is connected to the bearing plate 1 through screws 14. A fourth telescopic cylinder 16 is arranged at the top of the auxiliary support assembly 15. The fourth telescopic cylinder 16 is connected to the inner support assembly 4 through a bracket 17. By adjusting the height of the bracket 17, the connection state between the inner support assemblies 4 can be changed. With this structure, when it is necessary to completely remove the inner support assembly 4 from the thin-walled shell 1, the connection between the inner support assembly 4 and the inner mold 5 is released, and the fourth telescopic cylinder 16 plays a relay role to support the inner support assembly 4 on the third telescopic cylinder 13. At this time, the inner support assembly 4 is completely separated from the thin-walled shell 6, moved out of the steam curing sealing cavity to other predetermined positions, and then the next hole bearing plate cart 1 without the thin-walled shell 6 is moved under the inner support assembly 4 to complete the positioning of the inner support assembly 4. Then the inner mold 5 is installed and production is carried out again in the bottom die assembly 3, and the operation is convenient.

[0028] In a preferred embodiment, the auxiliary support assembly 15 includes a channel steel plate 1501, which is clamped to both sides of the load-bearing plate 1. The screw 14 is passed through the channel steel plate 1501 and the inner support assembly 4. One side of the channel steel plate 1501 is provided with a straight plate 1502. The lower part of the straight plate 1502 is connected to the mobile trolley 8 through a threaded sleeve 1503 and a screw rod 1504. The top of the screw rod 1504 is ball-jointed to the straight plate 1502. The threaded sleeve 1503 is threadedly connected to the screw rod 1504. The threaded sleeve 1503 is fixed at the bottom of the straight plate 1502. The screw rod 1504 is connected to the mobile trolley 8 through a sleeve 1505. The sleeve 1505 is fixed on the top of the mobile trolley 8. The screw rod 1504 is rotatably arranged on the sleeve 1505. The bracket 17 includes a triangular support 1701. Both sides of the triangular support 1701 are respectively provided with a top block 1702. A clamping groove 1703 is arranged in the top block 1702. The cross brace 401 is located in the clamping groove 1703. With this structure, the height of the channel steel plate 1501 and the straight plate 1502 can be adjusted by rotating and adjusting the threaded sleeve 1503, ensuring the precise and stable connection between the channel steel plate 1501 and the load-bearing plate 1. At the same time, the mobile trolley 8 located below the straight plate 1502 is in full contact with the ground, providing a stable supporting force for the fourth telescopic cylinder 16 and ensuring the safe and efficient jacking and landing of the inner support assembly 4.
