Specific embodiment
Embodiments of the invention are elaborated below, the present embodiment is carried out under premised on technical solution of the present invention
Implement, give detailed implementation method and specific operating process, but protection scope of the present invention is not limited to following implementations
Example.
Embodiment 1
As shown in figure 1, the complex load concrete platform in the present embodiment includes：Concrete foundation layer 1 and concrete surface
Layer 2, wherein：Concrete topping 2 is arranged on concrete foundation layer 1, and the upper surface of concrete topping 2 is coated with paving steel plate
3, pre-buried keel 5 are provided with concrete topping 2, some beard reinforcing bars 6 are provided between concrete topping 2 and concrete foundation layer 1,
The upper end of beard reinforcing bar 6 is arranged in concrete topping 2, and its lower end is arranged in concrete foundation layer 1.
Described pre-buried keel 5 are welded by i shaped steel.
Steel reinforcement cage is provided with described concrete foundation layer 1.
Mutually welded with steel reinforcement cage the lower end of described beard reinforcing bar 6.
The positioning angle steel 8 for positioning pre-buried keel 5 is provided with described concrete foundation layer 1, positioning angle steel 8 is by fixed
Position band iron 7 is connected with pre-buried keel 5.
The surface that described paving steel plate 3 is connected with concrete topping 2 is provided with the peg 4 for stretching into concrete topping 2.
The ratio between the described uniform equidistantly distributed of peg 4, the spacing L of peg 4 and thickness H of concrete topping 2 are less than or equal to 30.
As shown in Fig. 2 the construction method of described complex load concrete platform includes：
1) lay steel reinforcement cage, on steel reinforcement cage weld positioning angle steel 8 and beard reinforcing bar 6, casting concrete to specified absolute altitude,
Form mixed mud basal layer.Steel reinforcement cage is provided with concrete foundation layer 1, angle steel 8 will be positioned between casting concrete basis
It is fixed on steel reinforcement cage by way of spot welding with beard reinforcing bar 6.Steel reinforcement cage at positioning angle steel 8 position is double-deck double
To arrangement.
2) after positioning angle steel 8 upper end welding positioning band iron 7, the pre-buried keel 5 of bar trellis are welded in positioning band iron 7.
Need to carry out dabbing treatment to the surface of concrete foundation layer 1 before welding positioning band iron 7, to ensure concrete topping 2 and mix
The bonding of solidifying earth foundation layer 1.Positioning band iron 7 is one piece of square iron plate, is welded on positioning angle steel 8, for fixing pre-buried keel
5。
3) concrete as shown in figs. 34, is injected in each grid of pre-buried keel 5 and batten is placed along grid edge
