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 construction work, support scaffolding construction is a large amount of to be existed, and scaffold building method is substantially identical.But for setting up of first floor scaffold, in prior art, common way is at vertical rod lower berth wood springboard, then sets up vertical rod and cross bar, finally sets up sweep the floor bar and bridging.But because first floor scaffold bottom is the soil body, between soil body thawing period, for traditional erection method, still often can occur scaffold upright rod sinking situation, more serious meeting causes scaffold cave-in accident.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned deficiency of the prior art, there is provided a kind of scaffold subsidence problems solving scaffold and cause due to soil body freeze thawing, first floor support scaffolding structure and erection method between a kind of soil body thawing period preventing the generation of scaffold cave-in accident.
The technical scheme of scaffold of the present invention is: comprise horizon bar and the vertical rod of more than 2 piece that be fixedly installed crossing with horizon bar, wooden springboard is provided with between described vertical rod, the bottom of described vertical rod side is fixed with bar of sweeping the floor, described in sweep the floor between bar and wooden springboard and be provided with timber wedge.
First floor scaffold building method between a kind of soil body thawing period of the present invention, comprises the steps:
The first step. backfill the soil body routinely in set up horizon bar, vertical rod;
Second step carries out the construction of platform reinforced bar engineering and form work engineering;
3rd step lays wooden springboard between vertical rod space, and described wooden springboard and vertical rod are closely arrange;
Then 4th step arranges in the side of vertical rod and to sweep the floor bar, described in bar of sweeping the floor adopt the connected mode of pair fastener to be fixed with vertical rod;
Timber wedge is filled between the outside of the 5th step bar of sweeping the floor after fixation and wooden springboard;
6th step is in timber wedge arranged outside top, and described top, for follow closely on wooden springboard by steel nail, is moved in order to prevent timber wedge.
The height that bar of sweeping the floor in described step 4 is arranged is in wooden springboard epithelium position.
The invention has the beneficial effects as follows:
1. when setting up scaffold horizon bar, vertical rod, without the need to padding springboard below vertical rod, bar of sweeping the floor wouldn't be established, upper brace reinforced bar engineering and form work engineering normal construction, because its load when platform reinforced bar engineering, template construction is less, scaffold settling amount is minimum, can ignore, before the concrete of top to be built, between scaffold, lay wooden springboard, then establish bar of sweeping the floor, bar of sweeping the floor is close to wooden springboard as far as possible, finally will shift to an earlier date ready-made timber wedge fill in wooden springboard and sweep the floor between bar, and come directly towards with steel nail respectively outside timber wedge, move in order to prevent timber wedge.Therefore, the method takes the springboard of scaffold and bar of sweeping the floor is arranged before building, therefore construction period soil body freeze thawing is on the impact of final scaffold carrying nothing.
2. this method enforcement from before the vertical rod bearing load of prior art become vertical rod and sweep the floor the common bearing load of bar.
3. method is simple, can apply in building field large-scale popularization.

Detailed description of the invention
In order to understand the present invention further, describe structure and the embodiment of technical solution of the present invention in detail below in conjunction with accompanying drawing:
Shown in composition graphs 1, Fig. 2, Fig. 3, between soil body thawing period of the present invention, first floor scaffold comprises horizon bar 1 and the vertical rod 2 of more than 2 piece that be fixedly installed crossing with horizon bar 1, wooden springboard 3 is provided with between described vertical rod 2, the bottom of described vertical rod 2 side is fixed with bar 4 of sweeping the floor, described in sweep the floor between bar 4 and wooden springboard 3 and be provided with timber wedge 4.
Between a kind of soil body thawing period of the present invention, first floor scaffold building method step is: first. backfill the soil body routinely in set up horizon bar, vertical rod, i.e. scaffold, the scaffold upper load formed because of horizon bar, vertical rod is less, therefore little on the impact between soil body thawing period.After having set up horizon bar, vertical rod, normally can carry out the construction of platform reinforced bar engineering and form work engineering; Then wooden springboard is laid in the space between vertical rod and vertical rod, requires that wooden springboard is as far as possible close with vertical rod, is namely closely arranged during laying; Then in the side of vertical rod root, horizontally set is swept the floor bar, described in sweep the floor the height that bar arranges should in wooden springboard epithelium position, the fixed form of its sweep the floor bar and vertical rod, then adopt the connected mode of pair fastener to be fixed; After fixing, between the outside of bar of sweeping the floor and wooden springboard, arrange top, timber wedge is filled in described top namely, then follows closely with steel nail on wooden springboard by timber wedge, moves in order to prevent timber wedge.
The present invention is arranged when facing and building due to sweep the floor bar and wooden springboard, and in whole work progress, soil body freeze thawing is minimum on scaffold impact, therefore effectively prevent scaffold.
Claims (2)
1. a first floor scaffold building method between soil body thawing period, is characterized in that, comprise the steps:
The first step. on the soil body of backfill, set up horizon bar, vertical rod according to a conventional method;
Second step carries out the construction of platform reinforced bar engineering and form work engineering;
3rd step lays wooden springboard between vertical rod space, and described wooden springboard and vertical rod are closely arrange;
4th step arranges in the side of vertical rod and to sweep the floor bar, described in bar of sweeping the floor adopt the connected mode of pair fastener to be fixed with vertical rod;
Timber wedge is filled between the outside of the 5th step bar of sweeping the floor after fixation and wooden springboard;
6th step is in timber wedge arranged outside top, and described top, for follow closely on wooden springboard by steel nail, is moved in order to prevent timber wedge.
2. first floor scaffold building method between a kind of soil body thawing period according to claim 1, is characterized in that, bar of sweeping the floor in described step 4 is arranged on wooden springboard epithelium position.
