Abstract
Description
Technical Field
[0001] The utility model relates to a device for avoiding chiseling the surface of a square concrete lattice beam node for slope support. Background Art
[0002] With the excavation and construction of canal waterways in China, square lattice slope protection and reinforcement are widely used as permanent slope structures, which is one of the important projects for slope support and reinforcement.
[0003] At present, after the formwork is removed at the end position of the square lattice slope protection, chiseling is mostly carried out. The operation of chiseling the concrete surface with a chisel or a pneumatic pick to form a rough surface makes the stones on the concrete surface exposed, forming an uneven surface.
[0004] Since the square lattice beams are mostly small components (with a length and width within 0.5 m), large vibrations or collisions with the reserved steel bars inside and outside the beams are generated during chiseling, which may cause the gap between the steel bars and the concrete in the lattice beam to become larger, resulting in a reduction in the bond strength of the steel bars or damage to the steel bar protection layer. In addition, the traditional chiseling process requires a large amount of manpower, and the chiseling quality is uneven, and the resulting defects may affect the quality of the main project.
[0005] Therefore, in view of the above problems, a device for avoiding chiseling the surface of a square concrete lattice beam node for slope support is proposed. Content of the Utility Model
[0006] The purpose of the utility model is to provide a device for avoiding chiseling the surface of a square concrete lattice beam node for slope support, which reduces the chiseling process, reduces the labor cost, and effectively improves the construction efficiency.
[0007] The technical solution for achieving the above purpose is: a device for avoiding chiseling the surface of a square concrete lattice beam node for slope support, including a toothed rubber grout stop belt, a first reinforcing steel plate, a middle reinforcing steel plate, a plurality of first fixing bolts, an end formwork, and a second fixing bolt; the toothed rubber grout stop belt is placed on the end formwork, the first reinforcing steel plate presses the four sides of the toothed rubber grout stop belt, and the first reinforcing steel plate is connected to the end formwork through a plurality of the first fixing bolts; the middle of the toothed rubber grout stop belt is pressed by the middle reinforcing steel plate, and the middle reinforcing steel plate is connected to the end formwork through the second fixing bolt.
[0008] Preferably, the first reinforcing steel plate is in a square frame shape.
[0009] Preferably, the first fixing bolt passes through the first reinforcing steel plate, the toothed rubber grout stop belt, and the end formwork and is locked by a first nut.
[0010] Preferably, the second fixing bolt passes through the toothed rubber grout stop belt and the end template and is locked by a second nut.
[0011] The beneficial effects of the present utility model are as follows: The device for avoiding chiseling at the joint of the square concrete lattice beam for slope support of the present utility model realizes the avoidance of chiseling at the end joint position of the slope lattice beam by combining the toothed rubber grout stop belt with the end template, reduces the possible structural damage to such small square lattice beams during the chiseling process, and the connection structure is relatively simple and highly operable; The combination of the toothed rubber grout stop belt and the end template can be recycled more than 50 times, saving the cost of repeated chiseling by personnel; And the toothed rubber grout stop belt is a recycled material, which has the characteristics of environmental protection, energy conservation and low cost.

[0016] Next, the present utility model will be further described in conjunction with the drawings.
[0017] As Figure 1-2 shown, a device for avoiding chiseling at the joint of the square concrete lattice beam for slope support includes a toothed rubber grout stop belt 1, a first reinforcing steel plate 2, a middle reinforcing steel plate 3, a plurality of first fixing bolts 4, an end template 5 and a second fixing bolt 6;
[0018] Specifically, the toothed rubber grout stop belt 1 is placed on the end formwork 5, and the first reinforcing steel plate 2 presses the four sides of the toothed rubber grout stop belt 1. The first reinforcing steel plate 2 is in a double-square shape. The first reinforcing steel plate 2 is connected to the end formwork 5 through a plurality of first fixing bolts 4; the first fixing bolts 4 pass through the first reinforcing steel plate 2, the toothed rubber grout stop belt 1 and the end formwork 5 and are locked by first nuts 7.

The second fixing bolts 6 pass through the toothed rubber grout stop belt 1 and the end formwork 5 and are locked by second nuts 8.
[0019] Specifically, clean the end formwork 5, without stains, rust, etc. Measure accurately the position of the toothed rubber grout stop belt 1 to be installed (which can be cut according to size). Apply strong glue to the entire end formwork 5, and paste the toothed rubber grout stop belt 1 on the end formwork 5 of the square lattice beam. Use the first reinforcing steel plate 2 and a plurality of first fixing bolts 4 to fix the toothed rubber grout stop belt 1 here to prevent the toothed rubber grout stop belt 1 from falling off when the formwork is removed. After the overall installation is completed, connect and fix the entire device to the square lattice beam formwork. This structure is simple, easy to operate and install. After the concrete is poured and the end formwork 5 and the toothed rubber grout stop belt 1 are removed as a whole and recycled, a mirror toothed structure is formed at the end of the square lattice beam, which can well achieve the connection between concretes, can reduce the chiseling process, lower the labor cost, effectively improve the construction efficiency, reduce the disturbance of the steel bars of such small beam members caused by manual chiseling during the construction process, and ensure the construction quality of the end of the members.
