Description

Technical Field

[0001] This utility model relates to a grid key point casting device, belonging to the field of grid key point casting technology for slope protection. Background Technology

[0002] In lattice beam slope protection structures, the critical joints where the transverse and longitudinal reinforcement cages intersect are crucial load-bearing areas. However, current construction methods involve simultaneously erecting both longitudinal and transverse formwork at these points, severely restricting the working space and making concrete pouring difficult, as well as hindering the effective placement of vibrating equipment. The result is often insufficient concrete density at these critical points, leading to quality defects such as voids and honeycombing, which seriously affects the overall load-bearing capacity and durability of the lattice beam.

[0003] Therefore, there is a need for a lattice key point casting device that can facilitate the casting of key points and ensure the casting quality and structural reliability. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a lattice key point casting device, which can facilitate the casting of key points and ensure the casting quality and structural reliability; it can overcome the shortcomings of the prior art.

[0005] The objective of this utility model is achieved through the following technical solution: This utility model discloses a lattice key point casting device, which includes intersecting longitudinal and transverse steel cages. A "U"-shaped casting template is fixed on the outside of the longitudinal steel cage, and an "L"-shaped casting template is fixed on the outside of the transverse steel cage. A connecting plate is provided at the upper end of the longitudinal steel cage to connect with the outer baffles of the transverse steel cages on both sides. A reserved casting operation section is provided between the connecting plate and the upper longitudinal steel cage. A "U"-shaped sliding baffle that can move up and down is provided in the reserved casting operation section. A positioning device is provided on the "U"-shaped sliding baffle. A rear sealing baffle is provided between the "U"-shaped sliding baffle and the upper longitudinal steel cage.

[0006] The aforementioned structure for enabling the "U"-shaped sliding baffle to move up and down within the reserved pouring operation section includes a guide rod provided between the connecting plate and the upper longitudinal steel cage, and the "U"-shaped sliding baffle is sleeved on the guide rod.

[0007] The aforementioned positioning device includes a connecting sleeve provided on the outside of the "U"-shaped sliding baffle. The connecting sleeve cooperates with the guide rod. A screw hole is provided on the side wall of the connecting sleeve, and a fastening screw is provided in the screw hole.

[0008] As mentioned above, mounting seats for guide rods are provided on both the connecting plate and the upper longitudinal steel cage. External threads are provided at both ends of the guide rods, and positioning nuts are provided at both ends of the guide rods.

[0009] As mentioned above, both the "U"-shaped sliding baffle and the rear sealing baffle are formed by connecting the front baffle and the left and right baffles with reinforcing ribs. Reinforcing plates with rear sealing nails are provided between the "U"-shaped sliding baffle and the rear sealing baffle, between the "U"-shaped sliding baffle and the connecting plate, and between the rear sealing baffle and the upper longitudinal steel cage.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model solves the problem of severely limited operating space caused by "U"-shaped sliding baffles to the upper side of the reserved pouring operation section, and then fixes it by positioning device. When pouring the transverse reinforcement cage, the reserved pouring operation section allows for smooth pouring of key points. The reserved pouring operation section facilitates the operation of mechanical equipment. After the transverse reinforcement cage is poured horizontally, the "U"-shaped sliding baffle is slid to the bottom of the reserved pouring operation section, and then the "U"-shaped sliding baffle section of the longitudinal reinforcement cage is poured. After the "U"-shaped sliding baffle section is poured, it is sealed by the rear sealing baffle, and then the upper section of the longitudinal reinforcement cage is poured. This solves the problem that "U"-shaped and "L"-shaped pouring templates severely limit the operating space, making concrete pouring difficult and preventing vibrators from effectively reaching the target position, thus improving the quality of pouring.

[0011] 2. A guide rod is provided between the connecting plate and the longitudinal steel cage on the upper side. The "U"-shaped sliding baffle is sleeved on the guide rod. This structure allows the "U"-shaped sliding baffle to slide up and down easily through the guide rod.

[0012] 3. The positioning device includes a connecting sleeve provided on the outside of the "U"-shaped sliding baffle. The connecting sleeve cooperates with the guide rod. A screw hole is provided on the side wall of the connecting sleeve, and a fastening screw is provided in the screw hole. This structure facilitates the positioning of the "U"-shaped sliding baffle by fastening the screw.

A "U"-shaped casting template 3 is fixed to the outside of the longitudinal reinforcing cage 1, and an "L"-shaped casting template 4 is fixed to the outside of the transverse reinforcing cage 2. A connecting plate 5 is provided at the upper end of the longitudinal reinforcing cage 1, which connects to the outer baffles of the transverse reinforcing cages 2 on both sides. A reserved casting operation section 6 is provided between the connecting plate 5 and the upper longitudinal reinforcing cage 1. A "U"-shaped sliding baffle 7 that can move up and down is provided in the reserved casting operation section 6. A positioning device is provided on the "U"-shaped sliding baffle 7. A rear sealing baffle 8 is provided between the "U"-shaped sliding baffle 7 and the upper longitudinal reinforcing cage 1. With this structure, by sliding the "U"-shaped sliding baffle 7 to the upper side of the reserved casting operation section 6 and then fixing it by the positioning device, When pouring the transverse reinforcing cage 2, the reserved pouring operation section 6 allows for the smooth pouring of key points. The reserved pouring operation section 6 facilitates the operation of mechanical equipment. After the transverse reinforcing cage 2 is poured horizontally, the "U"-shaped sliding baffle 7 is slid to the bottom of the reserved pouring operation section 6, and then the "U"-shaped sliding baffle 7 section on the longitudinal reinforcing cage 1 is poured. After the "U"-shaped sliding baffle 7 section is poured, it is sealed by the rear sealing baffle 8, and then the upper section of the longitudinal reinforcing cage 1 is poured. This solves the problem that the "U"-shaped pouring template 3 and the "L"-shaped pouring template 4 severely restrict the operating space, making concrete pouring difficult and preventing the vibrating equipment from reaching the correct position, thus improving the quality of the pouring.

[0022] Furthermore, the structure that enables the "U"-shaped sliding baffle 7 to move up and down within the reserved pouring operation section 6 includes a guide rod 9 provided between the connecting plate 5 and the upper longitudinal steel cage 1.

[0023] Furthermore, the positioning device includes a connecting sleeve 10 provided on the outside of the "U"-shaped sliding baffle 7. The connecting sleeve 10 cooperates with the guide rod 9. A screw hole is provided on the side wall of the connecting sleeve 10, and a fastening screw is provided in the screw hole. This structure facilitates the positioning of the "U"-shaped sliding baffle 7 through the fastening screw.

[0024] Furthermore, mounting seats 11 for guide rods 9 are provided on both the connecting plate 5 and the upper longitudinal steel cage 1. External threads are provided at both ends of the guide rods 9, and positioning nuts 12 are provided at both ends of the guide rods 9. This structure facilitates the fixing of the guide rods 9 through the positioning nuts 12.

[0025] Furthermore, both the "U"-shaped sliding baffle 7 and the rear sealing baffle 8 are formed by connecting the front baffle and the left and right baffles with reinforcing ribs. Reinforcing plates 13 with rear sealing nails are provided between the "U"-shaped sliding baffle 7 and the rear sealing baffle 8, between the "U"-shaped sliding baffle 7 and the connecting plate 5, and between the rear sealing baffle 8 and the upper longitudinal steel cage 1. This facilitates on-site assembly through the front baffle and the left and right baffles. After assembly, the reinforcing ribs and reinforcing plates 13 are used to fix and connect the components with nails.

[0026] In use, the "U"-shaped sliding baffle 7 is slid to the upper side of the reserved pouring operation section 6 and then fixed by the positioning device. When pouring the transverse reinforcing cage 2, the reserved pouring operation section 6 allows for smooth pouring at key points. The reserved pouring operation section 6 facilitates the operation of mechanical equipment. After the transverse reinforcing cage 2 is horizontally poured, the "U"-shaped sliding baffle 7 is slid to the bottom of the reserved pouring operation section 6, and then the "U"-shaped sliding baffle 7 section on the longitudinal reinforcing cage 1 is poured. After the "U"-shaped sliding baffle 7 section is poured, it is sealed by the rear sealing baffle 8, and then the upper section of the longitudinal reinforcing cage 1 is poured. This device can improve the quality of pouring while reducing the difficulty of pouring.
