Abstract
A construction method for foundation bearing plates of movable load (apparatus) features that when pouring concrete foundation, uniformly arranged more bearing plates are put on plane of concrete foundation and the foundation bearing plate supporting system composed of more bearing plates is used as framework of apparatus foundation. The mortar for plate may be honding mortar No.25-100. Its advantages are less working amount and special bearing plates for steel rail, short construction period, high installation accuracy and ensuring quality of engineering.
Description
The present invention relates to a kind of job practices one continuous bed mortar soleplate method of Equipment Foundations backing plate of dynamic loading.
When developing a mine installation heavy type or large-scale dynamic loading electromechanical equipment, particularly on basic ground, need to be equipped with the engineering of annular rail in advance, basic ground is proposed higher levelness requirement, its traditional Equipment Foundations plastic sheet construction method adopts intermittently seat slurry method, generally be according to rail center size pre-embedded bolt when the pouring ground concrete, treat to grind the basis after the concrete setting, dig out seat slurry hole again at the concrete foundation position, flushing grouting, the configuration backing plate, the special-purpose backing plate of rail is installed then, is settled rail at last.This job practices ubiquity following problem: workload is big, long construction period, and the special-purpose backing plate quantity of rail is many, and horizontal accuracy is difficult for support to be held, and is difficult to reach installation specification, and often workmanship can't guarantee.Simultaneously, because basic ground horizontal accuracy is low, easily causes rail strength, rigidity to weaken, and also can cause mechanical oscillation thus, sinking at rail amount of deflection, mechanical oscillation and bearing can form vicious circle between the three, has shortened the equipment operating period.
The objective of the invention is defective at existing job practices existence, provide a kind of and grind that workload is little, the special-purpose backing plate of rail is few, can reach the continuous bed mortar soleplate method that the horizontal accuracy requirement is installed, it is not easy to cause rail strength, rigidity to weaken and sink at rail amount of deflection, mechanical oscillation and bearing and forms normal circulation between the three.
The objective of the invention is to realize: a kind of job practices of Equipment Foundations backing plate of dynamic loading by following technical proposals, it is when the cast base concrete, reserve the backing plate seat slurry hole and the anchor (bolt) hole of required setting, place the concrete foundation surface with equally distributed seat slurry plastic sheet form, and the frame construction on the bearing plate bearing system constitution equipment basis of forming by a plurality of seat slurry plastic sheets.Above-mentioned backing plate seat slurry can be selected the 25#-100# masonry mortar for use according to the requirement that the dynamic loading Equipment Foundations are installed.
The present invention is further described below in conjunction with embodiment.
A kind of continuous bed mortar soleplate method, be when the concreting basis, place on the concrete foundation face with a plurality of seat slurry plastic sheet forms, and the frame construction on the bearing plate bearing system constitution equipment basis of forming by a plurality of seat slurry plastic sheets, its operational sequence is: the backing plate seat slurry hole and the anchor (bolt) hole that reserve required setting when building base concrete, the base concrete initial set about 314 hours after, with stir the seat concrete grout pour into give stay the hole in and make firm by ramming, smash to starching the float gage layer in order to clapping slurry, after concrete surface water mark disappears, can settle backing plate and measure circularity and absolute altitude, backing plate upper surface absolute altitude limit deviation is ± 0.5mm, backing plate is placed in and uses hand hammer chock plate to knock the backing plate face after the seat slurry is gone up, make its steady decline, after backing plate circularity and absolute altitude are measured, make real the backing plate circumferential concrete, make into firm, concrete surface should be lower than backing plate face 2-5mm.Check backing plate absolute altitude and circularity once more before the initial set of seat concrete grout.Stone bolt and seat slurry plastic sheet carry out concreting synchronously, at any time adjust the center to center distance of bolt group, to guarantee the installation accuracy requirement, moist curing backing plate simultaneously waters, the length in seat slurry hole and width are than the length and the big 60-80mm of width of backing plate, and seat slurry hole is sunk to the surface of base degree of depth and is not less than 50mm.Backing plate can adopt common A3 steel plate, and width is greater than stone bolt center to center distance 30-50mm, and length is 50-100mm.The seat concrete grout is selected the 25#-100# masonry mortar for use, and its cementitious materials adopts plasticity phase and sclerosis later stage all to keep the non-shrinkage cement little with bleeding of microdilatancy or little contraction state, and sand adopts medium sand, and the stone granularity is 5-15mm.
Advantage of the present invention is: a traditional seat slurry method generally be after concrete foundation is solidified fully again Dig out seat slurry hole and operate, this law need not to cut a hole the hole and can construct continuously, and horizontal accuracy is easily transferred, and saves Labour, shortening duration, seat slurry layer and the synchronously sclerosis of basic layer, bonding power increases between them, can The contact area that guarantees backing plate reaches good state, embodies continuous operability and the integral body of installation Continuity.
For example, four concentrated machines in the iron ore constituency, Shanxi Taiyuan Iron and Steel Co. point mountain, about 400 tons of equipment gross weight, Its four concentrated machine track pads are installed the method for the present invention that all adopts, and have reached quality and have once tested Fold lattice, satisfy the requirement of design and installation technology, saved a large amount of manpower and financial resources, shortened the worker Phase, improved construction quality and operating efficiency, guaranteed that the normal operation of concentrated machine is used.
