Abstract
The invention discloses a first level of a support scaffold during the freezing and thawing period of a soil body and a building method. The first level of the scaffold comprises a horizontal rod and more than two vertical rods which are fixedly crossed with the horizontal rod; a wood springboard is arranged between the two vertical rods; a bottom horizontal rod is fixed at the lower end of one side of each vertical rod; and a wood wedge is arranged between the bottom horizontal rod and the wood springboard. The building method comprises the following steps of: building the horizontal rod and the vertical rods on the backfilled soil body according to the convention; constructing a platform reinforcing steel bar project and a template project; paving the wood springboard in a gap between the two vertical rods, wherein the wood springboard and the vertical rods are tightly arranged; arranging the bottom horizontal rod on one side of each of the vertical rod; fixing the bottom horizontal rod and the vertical rods in a connection way of double fasteners; plugging the wood wedge into the middle of the outer side of the fixed bottom horizontal rod and the wood springboard; and arranging the top head on the outer side of the wood wedge, wherein the top head nails a steel nail on the wood springboard and is used for preventing the wood wedge from moving.
Description
Technical field
The present invention relates to a kind of construction techniques, especially relate to the erection method of first floor support scaffolding between a kind of soil body thawing period.
Background technology
In the construction work, the support scaffolding construction is a large amount of to be existed, and the scaffold building method is basic identical.But for setting up of first floor scaffold, common way is the wood springboard in the vertical rod lower berth in the prior art, sets up vertical rod and cross bar then, sets up sweep the floor bar and bridging at last.But because first floor scaffold bottom is the soil body, between soil body thawing period, for traditional erection method, still scaffold upright rod sinking situation can often occur, more serious meeting causes the scaffold cave-in accident.
Summary of the invention
The technical problem that the present invention will solve is to overcome above-mentioned deficiency of the prior art; Provide a kind of scaffold that solves owing to the scaffold sinking problem that soil body freeze thawing causes, prevent first floor support scaffolding structure and erection method between a kind of soil body thawing period of generation of scaffold cave-in accident.
The technical scheme of scaffold of the present invention is: comprise horizon bar and intersect the vertical rod more than 2 that fixedly installs with horizon bar; Be provided with wooden springboard between the said vertical rod; The bottom of said vertical rod one side is fixed with the bar of sweeping the floor, and said sweeping the floor is provided with timber wedge between bar and the wooden springboard.
First floor scaffold building method between a kind of soil body thawing period of the present invention comprises the steps:
The first step. the soil body in backfill is set up horizon bar, vertical rod aspect conventional;
Second step was carried out the construction of platform reinforced bar engineering and form work engineering;
The 3rd step was laid wooden springboard between the vertical rod space, said wooden springboard and vertical rod are closely to be provided with;
The 4th step is then at a side setting of the vertical rod bar of sweeping the floor, the company that pair fasteners are adopted in said sweep the floor bar and vertical rod
The mode of connecing is fixed;
Fill in timber wedge between the outside of the 5th bar of sweeping the floor of step after fixing and the wooden springboard;
The 6th step, moved in order to prevent timber wedge for steel nail is followed closely on wooden springboard said top in timber wedge arranged outside top.
The height that the bar of sweeping the floor in the said step 4 is provided with is in wooden springboard epithelium position.
The invention has the beneficial effects as follows:
1. when setting up scaffold horizon bar, vertical rod, need not to fill up springboard below the vertical rod, the bar of sweeping the floor wouldn't be established; Upper brace reinforced bar engineering and form work engineering normal construction, its load is less during owing to platform reinforced bar engineering, template construction, and the scaffold settling amount is minimum; Can ignore, wait to build the top concrete before, between scaffold, lay wooden springboard; Establish the bar of sweeping the floor then, the bar of sweeping the floor is close to wooden springboard as far as possible, will shift to an earlier date ready-made timber wedge at last and fill in wooden springboard and sweep the floor between the bar; The top is done with steel nail respectively in the timber wedge outside, moves in order to prevent timber wedge.Therefore, the method is taked the springboard of scaffold and the bar of sweeping the floor is being built preceding setting, does not have influence so construction period soil body freeze thawing is carried final scaffold.
2. the enforcement of this method is become vertical rod and is swept the floor the common bearing load of bar by the vertical rod bearing load of former prior art.
3. method is simple, can use in the building field large-scale popularization.

The specific embodiment
In order further to understand the present invention, specify the structure and the embodiment of technical scheme of the present invention below in conjunction with accompanying drawing:
In conjunction with Fig. 1, Fig. 2, shown in Figure 3; First floor scaffold comprises horizon bar 1 and intersects the vertical rod more than 22 that fixedly installs with horizon bar 1 between soil body thawing period of the present invention; Be provided with wooden springboard 3 between the said vertical rod 2; The bottom of said vertical rod 2 one sides is fixed with the bar 4 of sweeping the floor, and said sweeping the floor is provided with timber wedge 4 between bar 4 and the wooden springboard 3.
First floor scaffold building method step is between a kind of soil body thawing period of the present invention: at first. the soil body in backfill is set up horizon bar, vertical rod aspect conventional; It is scaffold; Because of the scaffold upper load that horizon bar, vertical rod constitute less, therefore little to the influence between soil body thawing period.After having set up horizon bar, vertical rod, can normally carry out the construction of platform reinforced bar engineering and form work engineering; Wooden springboard is laid in space between vertical rod and vertical rod then, requires wooden springboard and vertical rod close as far as possible during laying, promptly closely is provided with; Then in a side of vertical rod root, the horizontally set bar of sweeping the floor, the height that the said bar of sweeping the floor is provided with should be in wooden springboard epithelium position, and the fixed form of its sweep the floor bar and vertical rod then adopts the connected mode of pair fasteners to fix; After fixing, between the outside of the bar of sweeping the floor and wooden springboard, the top is set, timber wedge is promptly filled in described top, with steel nail timber wedge is followed closely on wooden springboard then, moves in order to prevent timber wedge.
The present invention is because sweep the floor bar and wooden springboard are provided with facing when building, and in whole construction course, soil body freeze thawing is minimum to the scaffold influence, so prevented the scaffold sinking effectively.
