Embodiment Construction

[0019] combine figure 1 , figure 2 and image 3 , a method for fixing steel bar protective layer pads, comprising the following steps:

[0020] Step 1, preparing several blocks 1 with the same structure, each block includes an upper wall surface 101, a lower wall surface 102 and four side wall surfaces, the four side wall surfaces are respectively side wall surface one 103, side wall surface two 104, side wall surface three 105 and Side wall four 106, wherein the upper wall, lower wall and side wall one are planes, and side two, side three and side wall four are arc-shaped. The steel channel 2 is pre-embedded on the side close to the side wall surface 1, and the steel channel is a hollow structure with a rectangular cross section.

[0021] Step 2, take the matching steel belt 3 to pass through the steel channel, connect the pads in series to form a string of pads, after determining the set position of each pad on the steel belt, place a section of steel on both sides of th...

Abstract

The invention discloses a reinforcement protective cover cushion block fixing method, which comprises the following steps of: (1) preparing a plurality of cushion blocks with same structures, wherein each cushion block is a hexahedron, upper and lower surfaces and one side wall surface I of each cushion block are planes, a steel tank is embedded on one side of each cushion block close to the side wall surface I, and the other three side wall surfaces of each cushion block are arc surfaces; (2) using adaptive thin steel strips to penetrate through the steel tanks; connecting the cushion blocks in series to form a cushion block string; and pressing and bending steel strips on two sides of each steel tank; and (3) if a reinforcement framework is to be prefabricated, prefixing the cushion block string on a bound reinforcement framework by a steel strip; and then lifting the reinforcement framework into a template. According to the invention, the thickness of a reinforcement protective cover can be guaranteed; as the field bulk binding of the cushion blocks is changed into centralized prebinding, the field operation time can be greatly reduced, obvious technical and economic benefits are obtained, the fixing method is beneficial for accelerating construction progress and project investment is saved. The reinforcement protective cover cushion block fixing method disclosed by the invention is especially suitable for object side surfaces or bottom surfaces with small reinforcement distances and difficulties in binding the cushion blocks.

Description

technical field [0001] The invention relates to a method for fixing a steel bar protective layer cushion block. Background technique [0002] Too small thickness of the protective layer is the main reason for the premature corrosion of steel bars. Too small thickness of the protective layer not only shortens the time for the external corrosive medium to reach the steel bars, but also reduces the quality of the concrete within the protective layer, making the concrete in this area rich in slurry. Easy to crack. The thickness of the protective layer in the solid structure is locally too small, mainly because the number of protective layer pads is small or the pads are not fastened firmly, and they do not play the role of supporting steel bars. For structures with relatively dense steel bars and relatively small thickness of the protective layer, star-shaped pads are mostly used. There are two types of existing fixing methods for star-shaped pads. The block is bound on the st...
