Further, to guarantee being stably connected between inclined plate, while in order to which supporting module is combined, the design it
It further include transverse tube 5, the transverse tube 5 is sequentially passed through after the perforation 12 at the middle part of each inclined plate by the inclined plate of supporting module one end from support
The inclined plate of the module other end is pierced by, meanwhile, the transverse tube 5 is same long with supporting module, and the both ends of transverse tube 5 are respectively welded and have
The connecting plate 6 of fixation hole；It also is fixedly connected with connecting tube 7 at the middle part of the transverse tube 5, connecting tube 7 and transverse tube 5 are in decussation
Setting, and the length of connecting tube 7 and upper backup pad 1 is of same size, and the both ends of connecting tube 7 are respectively equipped with mounting hole 9
Fixed plate 8, be also fixed with module connecting plates on the lower supporting plate in forefront before being located at supporting module on extreme direction
4, module connecting plates 4 and lower supporting plate are equipped with lower fixed mounting hole 10, and the lower fixed mounting hole 10 being located on lower supporting plate
Oval or rectangle, meanwhile, upper fixed mounting hole 11 is equipped on upper backup pad.
The design is equipped with waterproof layer of cloth 23 and supporting network 24(steel mesh also between the upper plate layer and upper backup pad), it is described
Waterproof layer of cloth is located at 24 top of supporting network, and supporting network 24 is fixedly connected with (welding) with upper backup pad 1.
Further, the upper plate layer is fixedly connected by upper bolt 25 with upper backup pad 1, meanwhile, the upper bolt 25
Upper end be embedded in the upper concrete layer 21 on upper plate layer Nei and pass through upper reinforcing bar stratum reticulare 22；Meanwhile it being equipped on upper bolt 25
Two spaced upper plates 26 and lower plate 27, upper plate 26 and lower plate 27 are fixed with upper bolt welding, and on reinforcing bar stratum reticulare
Plate 26 and lower plate 27 clamp.And the lower plate layer is fixedly connected by lower bolt 28 with each lower supporting plate 2, the lower bolt 28
Lower end is embedded in the lower concrete layer 30 on lower plate layer.
The superstructure of the design can construct in accordance with the following steps in construction:
1, lower steel mesh is laid in support shuttering (prior art), then consolidates the lower end of lower bolt by the construction of lower plate layer
It is scheduled on lower reinforcing bar stratum reticulare, casting concrete completes the construction of lower concrete layer, after the lower concrete layer solidification on lower plate layer
It can carry out lower step construction.
2, supporting module is assembled, supporting module is completed in factory to standardization in advance as unit of individual module
Production, is transported later to construction site, single supporting module is hung to one by one on upper plate layer using lifting equipments such as tower cranes,
When installation, the lower fixed mounting hole 10 on lower supporting plate is covered on lower bolt according to predeterminated position, is revolved on lower bolt later
Lower supporting plate is fixed in tight nut.
In construction, when front-rear direction docks, the module in supporting module being located behind connects two neighboring supporting module
Fishplate bar 4 is pressed in front support module, on the lower supporting plate in caudal end, and the lower fixed peace on module connecting plates 4
Dress hole 10 is connect with the lower supporting plate by lower bolt 28, at this point, the connecting plate 6 of the two neighboring transverse tube end of front and back setting is right
It connects and passes through the first transverse tube connection bolt 29 and fix, as shown in Figure 2.
In construction, when two neighboring supporting module is docked in left and right directions, two neighboring 7 end of supporting module upper connector
Docking, and bolt is connected by the second transverse tube after the docking of fixed plate 8 of 7 end of two neighboring connecting tube and is fixedly connected.
Multiple supporting modules can be assembled in the manner described above, until gross area is laid with this support on entire upper plate layer
Module.
3, it is laid with supporting network on upper backup pad, in the construction of this step, needs to weld supporting network and upper backup pad,
The effect that supporting network may be implemented as support shuttering in welding is carried out by supporting network and upper backup pad, is convenient for subsequent construction, with
It avoids that the movement of supporting network position, concrete is caused to push supporting network and rouse phenomena such as causing personnel's pressure to step in subsequent construction
Phenomena such as packet, support performance reduce.
Upper bolt is welded on one by one in upper fixed mounting hole 11 later, is then laid with waterproof layer of cloth 23, this waterproof cloth
Layer 23 should have barrier concrete and water effect, this waterproof layer of cloth 23 construction when mainly substitute support shuttering, avoid using
Support shuttering, this waterproof layer of cloth 23 of later period are mainly used for waterproof, water are avoided to cause corruption to supporting module between upper and lower plate layer
Erosion.
4, the construction of upper plate layer；After waterproof layer of cloth 23 is laid with, lower plate 27, lower plate 27 are welded at the middle part of upper bolt 25 first
It should be spaced and be arranged with waterproof layer of cloth 23, later, reinforcing bar stratum reticulare in layings, in laying when reinforcing bar stratum reticulare, general by welding
Upper reinforcing bar stratum reticulare is welded with lower plate, upper plate 26 is then welded on the upper bolt on the upside of upper reinforcing bar stratum reticulare, while by upper plate
It being welded with upper reinforcing bar stratum reticulare, reinforcing bar stratum reticulare upper in this way can be vacantly arranged by welding with upper plate layer, meanwhile, pass through
This mode, upper reinforcing bar stratum reticulare can be supported by supporting module, and construction personnel can construct on upper reinforcing bar stratum reticulare, hereafter
Concrete layer construction can be carried out pouring, after the solidification of upper concrete layer, can by the support shuttering that lower plate layer is supported into
Row is removed, the constructing operation of so far achievable superstructure.
What the embodiment of the present invention was announced is preferred embodiment, and however, it is not limited to this, the ordinary skill people of this field
Member, easily according to above-described embodiment, understands spirit of the invention, and make different amplification and variation, but as long as not departing from this
The spirit of invention, all within the scope of the present invention.
