Description

Technical Field

[0002] With the development of my country's infrastructure, the construction of waterways and canals, and the construction of highways, square lattice slope protection and reinforcement are widely used as permanent slope support structures, and are one of the important projects of slope support and reinforcement. The square lattice slope protection is located on the slope and is affected by rainfall, atmosphere, erosion and other environments all year round. Some slope protection is located on the waterway slope protection, which is affected by water level changes and microbial erosion. The thickness of the square lattice slope protection steel bar protection layer is a key factor in improving the erosion resistance and durability of this concrete structure.

[0003] At present, the conventional method for controlling the protective layer of square lattice slope is to use protective layer pads for control, and the pads are used for support at the bottom and sides, and the steel skeleton is adjusted and installed to the specified position. The steel bars used in this lattice beam have a small diameter and poor rigidity, and the operators need to make adjustments many times. During the pouring of concrete, the pads fall off and the steel skeleton is dislocated due to the influence of the concrete side pressure, the vibration of the vibrating rod, the concrete impact, etc., especially when pouring concrete on the slope surface, the steel skeleton is very easy to float or sink, resulting in the thickness of the steel protective layer being too large or too small, which cannot meet the design and specification requirements. Therefore, a steel skeleton protective layer control device for square lattice beams is proposed to address the above problems. Utility Model Content

[0017] AsFigure 1-2 As shown in the figure, a control device for the protective layer of the steel bar skeleton of a square lattice beam includes a transverse angle steel 1, two groups of main bar floating positioning components, and two groups of fixing components; one group of main bar floating positioning components is arranged at each end of the transverse angle steel 1 for fixing the steel bar skeleton; one group of fixing components is arranged on each side of the two groups of main bar floating positioning components on the transverse angle steel 1 for connecting the transverse angle steel 1 with the formwork.

[0018] Specifically, the main bar floating positioning component includes an L-shaped limiting rod 2. A through hole is opened on the transverse angle steel 1, and the L-shaped limiting rod 2 penetrates through the through hole. A baffle 3 is connected to the side wall of the L-shaped limiting rod 2 above the through hole; a limiting block 4 is connected to the lower end face of the transverse angle steel 1, and the limiting block 4 is located inside the L-shaped limiting rod 2.

A waist-shaped hole 6 is opened at the end of the transverse angle steel 1, and the bolt 5 penetrates through the waist-shaped hole 6 to connect the formwork. One positioning block 7 is connected to each end of the transverse angle steel 1, and the positioning block 7 is located inside the bolt 5.

[0019] Specifically, during installation, the positioning blocks 7 at both ends respectively abut against the formworks on both sides, and the two ends of the transverse angle steel 1 are fixed on the formworks on both sides by using the bolts 5 on both sides. The steel bar skeleton is inserted between the limiting block 4 and the L-shaped limiting rod 2 to fix the steel bar skeleton and ensure that the steel bar skeleton does not sink during the concrete pouring process.

[0020] Specifically, in combination with the width of the square lattice beam, the spacing of the main bars of the steel bar skeleton, and the main bar protective layer, the top transverse angle steel 1 is fabricated according to the width of the beam. The L-shaped limiting rod 2, the limiting block 4, the baffle 3, and the positioning block 7 are welded according to the design requirements (spacing and protective layer). Waist-shaped holes 6 are arranged on both sides of the transverse angle steel 1. After the whole device is processed, the bolt 5 is fixed to the formwork through the waist-shaped hole, and the steel bar skeleton is firmly fixed at the designed position (between the L-shaped limiting rod 2 and the limiting block 4).

[0021] The steel bar framework protective layer control device for the square lattice beam can not only ensure the accurate positioning of the protective layer size of the square lattice beam, but also reinforce the steel bar cage. The top uses the transverse angle steel 1 as the main support body, and the lifting hooks (main bar floating positioning components) are set according to the situation of the steel bar framework to ensure that the steel bar framework does not sink during the concrete pouring process, ensure the main bar spacing, and at the same time prevent the steel bar cage from floating during the pouring process; the positioning block 7 is set to accurately clamp the inner cross-sectional size of the beam, prevent the device from shaking left and right and control the beam cross-sectional size; waist-shaped holes 6 are arranged on both sides of the device for fixing the transverse angle steel 1 on the formwork (fixed by bolts or buckles); after the concrete pouring is completed, the L-shaped limiting rod 2 is rotated by rotating the cross bar 8, the steel bar framework is loosened, and then the bolt 5 is loosened to take out the device. This device is simple to manufacture and convenient to install, and can well prevent the deviation of the steel bar framework, the floating and sinking of the steel bar framework caused by insufficient stiffness or insecure reinforcement of the steel bar framework, and control the steel bars in place at one time, so that the protective layer thickness can be effectively controlled.

After the installation is completed, the steel bar framework can be in place in one step, and the construction efficiency is improved; moreover, the structure is simple, the operability is strong, and it has good economy and practicability.
