Abstract
The invention relates to a construction method for a reserved hole of an equipment foundation bolt. The construction method is characterized by comprising the following steps: firstly selecting a columnar square pillar with a proper size according to the size of the reserved hole of the bolt, laminating a thin foam plate on the embedded part of the lower part of the square pillar, tightly enwinding plastic paper to wrap the square pillar, well fixing the square pillar before casting concrete, and then casting the concrete, casting the part, on which the plastic paper is enwound, of the square pillar into the concrete; after the concrete is solidified, pulling out the square pillar, mashing the foam plate, irrigating water into the hole so as to flush away the foam. The construction method has the advantages of simple construction process, convenience of template removal, cost-saving property, ensured construction quality and greatly improved construction efficiency.
Description
Technical field
The present invention relates to a kind of construction method of apparatus foundation bolt preformed hole, belong to equipment installation Technology field.
Background technology
In the foundation construction that business equipment is installed, because equipment itself is complex-shaped various, cause basic end face to there is multiple different absolute altitude, this just requires that the bolt box position on connection device and basis is very accurate, requires that the concrete of final grouting and basis connect stubble reliable simultaneously.
In bolt box construction technology traditional in the past, the general wooden model that adopts installs preformed hole, conveniently can extract smoothly after concreting, often preformed hole template construct is become the lower large and wedged template that surface is very smooth young, suitable for reading.After this template is extracted, the general smoother of concrete surface, because template is lower little greatly upper, when pre-embedded bolt, the concrete that secondary is built and base concrete caking property very poor, add the contraction of secondary concreting, in equipment running process bolt be easy to loosen even be pulled out.In addition, when some preformed hole degree of depth are less, also adopt steel pipe to replace the technique of wooden model, establish special messenger constantly to rotate steel pipe when concreting, finally before concrete setting, extract steel pipe.
Along with updating of construction technology, some units in charge of construction start the technology adopting a kind of advanced person, namely utilize a kind of bolt sleeve by professional production manufacturer production.But in the construction of reality, model and the quantity of the bolt hole needed for each equipment Foundations are relatively less, if all entrust specialized factory to produce, this is unpractical.
In sum, traditional construction technology construction is complicated, reliability is low, not easy to operate; Then construction cost is improve by the bolt sleeve of professional production manufacturer production, and cannot extensive use in reality construction.
Summary of the invention
The object of this invention is to provide that a kind of construction technology is simple, form removal convenient, cost-saving, the construction method that ensures construction quality, apparatus foundation bolt preformed hole that efficiency of construction is high.
Technical scheme of the present invention is as follows:
First suitable column flitch is chosen according to the size dimension of bolt box, the pre-buried part of flitch bottom attaches the thin cystosepiment of one deck, and be wrapped on flitch with plastic paper winding tightly, before concreting, flitch is fixed, carry out concreting, the part being tied with plastic paper of flitch is cast in concrete, after concrete setting, extracts flitch, again cystosepiment is smashed to pieces, then pour water in hole and foam gone out.
Described column flitch preferred hexahedron column flitch.
Advantage of the present invention is: construction technology is simple, and form removal is convenient, and cost-saving, construction quality is guaranteed, and efficiency of construction is significantly heightened.
Accompanying drawing explanation
Fig. 1 is that flitch of the present invention buries schematic diagram underground.
In figure: 1. concrete foundation, 2. flitch, 3. cystosepiment.
Detailed description of the invention
Embodiment:
Company undertakes the construction of in the construction of cloud horse aircraft factory equipment Foundations, and the concrete foundation face of equipment exists multiple different absolute altitude, and the bolt box in concrete foundation has the specification requirement of the multiple degree of depth and thickness.The present embodiment selects the bolt box of a kind of specification wherein to be described.With reference to accompanying drawing 1, first suitable hexahedron column flitch 2 is chosen according to the size dimension of bolt box, the pre-buried part of flitch bottom attaches the thin cystosepiment 3 of one deck, and be wrapped on flitch with plastic paper winding tightly, before concreting, flitch is fixed, carry out concreting, the part being tied with plastic paper of flitch is cast in concrete, flitch is extracted after concrete foundation 1 is solidified, again cystosepiment is smashed to pieces, then pour water in hole and to be gone out by foam, bolt box has been constructed.Due to the pre-buried part of flitch being pasted with thin cystosepiment, without the need to making flitch movable in the process on concreting basis, be easy to extract flitch after concrete foundation is solidified, be wrapped in the plastic paper outside thin cystosepiment just broken in the process of concreting, and the thin cystosepiment stayed in preformed hole is easy to pulverize, foam of pouring water in preformed hole floats, and goes out outside hole.The upper and lower thickness of such bolt box is consistent, shows that fineness is poor, when pre-embedded bolt, the concrete that secondary is built and base concrete caking property very good, pre-buried bolt is very firm.Method of the present invention is used widely in the repeatedly construction of applicant, also demonstrates method construction technology of the present invention simple, and form removal is convenient, and saved cost, ensure that construction quality, efficiency of construction is significantly heightened.
Claims (2)
1. the construction method of an apparatus foundation bolt preformed hole, it is characterized in that: first choose suitable column flitch according to the size dimension of bolt box, the pre-buried part of flitch bottom attaches the thin cystosepiment of one deck, and be wrapped on flitch with plastic paper winding tightly, before concreting, flitch is fixed, carry out concreting, the part being tied with plastic paper of flitch is cast in concrete, flitch is extracted after concrete setting, again cystosepiment is smashed to pieces, then pour water in hole and foam gone out.
2. the construction method of apparatus foundation bolt preformed hole according to claim 1, is characterized in that: described column flitch is hexahedron column flitch.
