Problems solved by technology
[0002] In reinforced concrete construction projects, the control of the distance between the steel cage net and the bottom formwork and wall formwork is very important. The methods commonly used in the prior art are: 1. Point-type several-shaped stirrup iron control; 2. Long stirrup control ; 3. Control of spot welded stirrup frame; 4. Control of padding concrete block; 5. Schemes such as padding plastic block control. Displacement prone to occur during pouring
1, 2, and 3 schemes have no additional protective layer, or when the additional protective layer is not good, the exposed ribs will not only affect the appearance, but also the long-term cumulative corrosion will affect the bonding force between the steel bar and the concrete and reduce the strength
The 5 scheme is artificial foreign matter, it is difficult to have a consistent cohesive force, and it is easy to form holes that reach the gaps in the main ribs after aging and deformation

Embodiment Construction
[0015] In conjunction with the accompanying drawings of the description, the prefabricated concrete module support of the steel cage net of the present invention is described in further detail:
[0016] Such as figure 1 As shown, the reinforced cage mesh prefabricated concrete module support of the present invention is to arrange the fixed module 3 through the binding wire 4 on the steel bar 2 between the template 1 and the reinforced cage mesh to control the distance between the reinforced cage mesh and the template 1. Such as figure 2 , image 3 , Figure 4 As shown, the module 3 is a cross double wedge concrete block, and the module surface 5 is provided with a longitudinal arc-shaped reinforcement groove 6, and the binding wire 4 of the pre-embedded tap on both sides of the reinforcement groove 6 is narrowed longitudinally at a large angle from the module surface 5 , the horizontal small angle is relaxed to form a horizontal narrow rectangular module bottom 7.

The invention provides a reinforcement cage net precast concrete module bracket which comprises a template, a cage net reinforcing steel bar and a module; the reinforcement cage net precast concrete module bracket is characterized in that the fixing module is arranged between the template and the cage net reinforcing steel bar and is used for controlling the distance between the template and the cage net reinforcing steel bar; a binding line is arranged on the module, so that the module can be accurately located; a reinforcing steel bar groove is formed, so that the longitudinal movement of the module can be prevented; the module is prevented from transverse movement taking the reinforcing steel bar as a center due to the design of a narrow wedge-shaped plane of the bottom surface. Compared with the prior art, the reinforcement cage net precast concrete module bracket has the characteristics of being simple in structure, easy to manufacture, convenient to use and the like, and particularly has the advantages of being firm in fixation, unified in height and consistent in the used material, so that thickness of a reinforcement cage net protective layer is accurate and even, and the best effect is exerted; therefore, the reinforcement cage net precast concrete module bracket has good popularization and application values.
Description
1. Technical field: [0001] The invention belongs to construction engineering, in particular to a prefabricated concrete module support with steel cage mesh. 2. Background technology: [0002] In reinforced concrete construction projects, the control of the distance between the steel cage net and the bottom formwork and wall formwork is very important. The methods commonly used in the prior art are: 1. Point-type several-shaped stirrup iron control; 2. Long stirrup control ; 3. Control of spot welded stirrup frame; 4. Control of padding concrete block; 5. Schemes such as padding plastic block control. Displacement is prone to occur during pouring. In schemes 1, 2, and 3, there is no additional protective layer, or when the additional protective layer is not good, the exposed ribs will not only affect the appearance, but also the long-term cumulative corrosion will affect the bonding force between the steel bar and the concrete and reduce the strength. Option 5 is an artific...
