Description
Technical field
The present invention relates to the realm of building construction, more particularly to a kind of construction method of shallow foundation stay in place form.
Background technology
Currently, with the rapid development of modern architecture industry, the continuous renewal of construction techniques, underground infrastructures are more next
It is more complicated, it is desirable that higher and higher.And underground infrastructures engineering casting concrete would generally be come using conventional mould, steelframe mostly
As support, using the molding mode of conventional mould, need to use a large amount of material, construction speed is slow and form bracing system not
Surely, architecture quality problem is easy tod produce.
Invention content
The present invention provides a kind of construction method of shallow foundation stay in place form, to solve above-mentioned technology existing in the prior art
Problem.
In order to solve the above technical problems, the present invention provides a kind of construction method of shallow foundation stay in place form, including：
Step 1：Earth excavation；
Step 2：In the earthwork bottom construction bearing platform bed course and set up steel reinforcement cage on the cushion cap bed course；
Step 3：In the side installation form of steel reinforcement cage；
Step 4：The backfill in the earthwork of template surrounding pours cushion cap concrete.
Preferably, in the step 1：It is excavated from top to bottom at the construction field (site), and earthwork both sides are slope.
Preferably, the template uses steel plate, aluminium sheet or plastic plate.
Preferably, in the step 2：Protective layer cushion block, the protective layer cushion block are set while setting up steel reinforcement cage
Region between steel reinforcement cage and template.
Preferably, the protective layer cushion block is piled up using concrete, and its concrete strength for using and step 4
The concrete strength of middle use is identical.
Preferably, in the step 4, when the height for filling backfill is flush to the tip height of steel reinforcement cage, in steel
Cushion cap concrete is poured in muscle cage.
Compared with prior art, the construction method of foundation structure template of the invention, including：Step 1：Earth excavation；Step
Rapid 2：In the earthwork bottom construction bearing platform bed course and set up steel reinforcement cage on the cushion cap bed course；Step 3：In the side of steel reinforcement cage
Face installation form；Step 4：The backfill in the earthwork of template surrounding pours cushion cap concrete.The present invention can reduce construction work
Sequence largely reduces the turnover equipment material such as template 5, timber, steel pipe, fastener under the premise of ensuring architecture quality construction safety
It uses, project scale is bigger, and cost reduction is more apparent.In addition, the present invention is simple to operation, template stress system more adapts to more
The construction operating mode of change.

Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings to the present invention
Specific implementation mode be described in detail.It should be noted that attached drawing of the present invention is all made of simplified form and uses non-essence
Accurate ratio, only for the purpose of facilitating and clarifying the purpose of the embodiments of the invention.
The present invention provides a kind of construction method of shallow foundation stay in place form, including：
Step 1：It is excavated as shown in Figure 1, carrying out the earthwork 1 from top to bottom at the construction field (site), certainly, excavation should be by design grade
1 both sides of slope, that is, earthwork are slope, are excavated from top to bottom, and take corresponding measure depending on the case where geology.
Step 2：As shown in Fig. 2, in 1 bottom construction bearing platform bed course 4 of the earthwork and setting up steel on the cushion cap bed course 4
Muscle cage 3 specifically carries out setting and assembling reinforcement while cushion cap bed course 4 is constructed using concrete, is put into protective layer cushion block 2,
The region of the protective layer cushion block 2 between steel reinforcement cage 3 and template 5, for carrying out protection to template 5
Step 3：As shown in figure 3, in the side installation form 5 of steel reinforcement cage 3, specifically, the template 5 is certain using having
The steel flexible thin or other materials flexible thin of rigidity, such as aluminium sheet, plastic plate, 5 stress system of template more adapts to changeable
Construction operating mode.Further, template 5 of the invention is no longer needed to reinforce and be supported, and stress system more adapts to changeable construction
Operating mode, and subsequently no longer need to carry out dismounting process, reduce working procedure, reduce cost, accelerates construction speed, economic benefit
It is significantly improved.
Step 4：As shown in figure 4, the backfill 6 in the earthwork 1 of 5 surrounding of template, waits for the height and steel reinforcement cage 3 of backfill 6
Height when flushing, cushion cap concrete seven is poured in steel reinforcement cage 3.
Preferably, the protective layer cushion block 2 is piled up using concrete, and its concrete strength for using and step
The concrete strength used in 4 is identical.
Above-mentioned construction method using the present invention, it is possible to reduce working procedure, before ensuring architecture quality construction safety
It puts, largely reduces the use of the turnover equipment material such as template 5, timber, steel pipe, fastener, project scale is bigger, and cost reduction is brighter
It is aobvious.In addition, the present invention is simple to operation, template stress system more adapts to changeable construction operating mode.
Obviously, those skilled in the art can carry out invention spirit of the various modification and variations without departing from the present invention
And range.If in this way, these modifications and changes of the present invention belong to the claims in the present invention and its equivalent technologies range it
Interior, then the present invention is also intended to including these modification and variations.
