Background technology
Nowadays among engineering process in itself, foundation engineering is as most important link, in the quality and progress of engineering
Very important effect is played in control process.Therefore how preferably to lift the quality of foundation engineering and speed up the work simultaneously
It is capable of the cost-effective of maximum, is a problem in engineering construction.
Brick mold is to replace plank sheathing or steel form to be mainly used in foundation beam, hold come a kind of method of formwork with brick setting
The side forms such as platform, elevator, catch pit are not easy the position removed, and are a kind of traditional construction technologies.But brick mold builds work by laying bricks or stones
Journey amount is larger, and input manpower is more, work efficiency is low, speed of application is slow, cost is higher.
The content of the invention
The invention aims to solve the above problems, there is provided a kind of construction that foundation platform is made by precast concrete
Technique is specially a kind of by the directly assembled making foundation platform of precast concrete（Grade beam）Construction technology.It can effectively be prevented
The problems such as brick mold that backfill is extruded and occurred is collapsed, deformed, crack occurs, and it is fast to shorten duration, speed of application, work efficiency
Height, cost-effective, green construction, achieve good economic benefit.
In order to reach foregoing invention purpose, the present invention uses following technical scheme：
A kind of construction technology that foundation platform is made by precast concrete, comprises the following steps：Precast concrete is processed in batch production, is surveyed
Unwrapping wire is measured, earth excavation, cushion cap or ground beam is poured, puts loose tool line, prefabricated moulding bed plate is installed, cushion cap or the backfill of ground beam sides are flat
Whole, check of foundation subsoil pours blinding layer；
Precast concrete is processed in batch production, that is, processes prefabricated moulding bed plate；
Earth excavation, more than mechanical earth excavation to cushion cap bottom 200 ㎜ are artificial clear native, smooth；Foundation ditch finishing soil after excavation
Bar dowel head is stamped on face, as bed course position and thickness control point；
Pour cushion cap or ground beam, the foundation ditch or groove of cushion cap or grade beam excavate and check of foundation subsoil after, construction bearing platform and grade beam heelpiece
Layer, bed course side extends out 100mm than cushion cap and grade beam sideline；
Loose tool line is put, after blinding concrete intensity reaches 1.5Mpa, upper people's surveying setting-out, prefabricated moulding bed plate is ejected with ink fountain and installs
Line, installation control line, cushion cap or grade beam axis；
Prefabricated moulding bed plate is installed, specially arranged sheet material by live length, short slab is cut using portable cutting machine, under plate mouth with connect
Cement mortar seat slurry is laid at head, highly more than 0.6m or length is more than 3.0m and sets fourth plate, and the upper and lower fissure of displacement, fourth in lower floor
Plate termination is blocked using concrete, and concrete prefabricated board both sides are fixed using bar dowel head and prevent from shifting, and seam is pasted grid and prevented
Split band；The height of prefabricated moulding bed plate is lower 2cm than depth of beam；
（7）Cushion cap or the backfill of ground beam sides are smooth；With 2 between prefabricated moulding bed plate and side slope：8 dirt are filled, compaction in layers,
（8）Check of foundation subsoil pours blinding layer.
Preferably, when pouring cushion cap bed course, positioning hole, position of the positioning hole along prefabricated moulding bed plate are reserved on cushion cap bedding plane
Put and be uniformly distributed, and be two row.
Preferably, the precast concrete material size is 3 × 0.6 × 0.09m.
Preferably, work technique is applied to the construction at the position such as foundation beam, cushion cap, catch pit in architectural engineering.
Preferably, the height at the position such as the foundation beam, cushion cap, catch pit is less than or equal to 1.2m.
Compared with prior art, beneficial effect is the present invention：
This construction method of brick mold is substituted using precast concrete, the duration is shortened, improves speed of application, improve work efficiency,
Cost, green construction have been saved, and has achieved good economic benefit.
Specifically, substantial amounts of construction brick and cement have been saved, energy-conserving and environment-protective, and by shaping sheet material assembling i.e. dress i.e.
With, without waiting for masonry cement solidify, shorten construction period.By reinforcing on the outside of brick mold, effectively prevent because backfill is squeezed
The problems such as brick mold pressed and occurred is collapsed, deformed, crack occurs.Assembling between splice plate is rapid and firm, saves a large amount of
Engineering time.
Brief description of the drawings
Fig. 1-4 is that the precast concrete of the present invention makes the construction technological process figure of foundation platform or grade beam；
Fig. 5-6 is that the precast concrete of the present invention makes the reinforcing joint detail drawing of foundation platform or grade beam.
In figure：1 cushion cap or ground beam, 2 prefabricated moulding bed plates.
Embodiment
Explanation is further described to technical scheme below by specific embodiment.
