Description
Technical field
The present invention relates to field of civil engineering, specifically is a kind of concrete foundation and job practices thereof that in the industrial building, is used for fixing plant equipment.
Background technology
Heavy mechanical equipment in the factory building of factory is the vibrations displacement in order to prevent to move, and generally need plant equipment be fixed on the concrete foundation of factory building.Concrete foundation is exactly the reinforced concrete block that is used to shelve solid mechanical equipment in fact; It is square anchor (bolt) hole that the end face of concrete foundation is reserved with cross section; With stone bolt place in the anchor (bolt) hole and the top of stone bolt on protrude bolt hole; Concreting slurries in the hole make foot bolt fastening in anchor (bolt) hole again, and utilization at last is anchored at stone bolt and the plant equipment of protruding concrete foundation in the bolt hole and on the top and fixes.
The job practices of the concrete foundation that is used for fixing plant equipment of prior art is following:
A, water and smash concrete cushion;
B, on concrete cushion, shelve steel mesh reinforcement, and on lower floor's steel mesh reinforcement welding split heads muscle;
C, vertically place four wooden forms of drawing close each other; The end face absolute altitude level of the absolute altitude of the end face of four wooden forms and concrete foundation; The plan view shape of four vertical wooden forms is a hollow, is the top that top reinforcement hoop that groined type distributes is enclosed within four wooden forms with four, specifically; The top of four wooden forms is bound round in the mouth word of groined type central authorities that cover is clamped on four top reinforcementes, and four top reinforcementes and top mat spot welding are fixed;
D, be the lower part that lower floor's stirrup that groined type distributes is enclosed within four wooden forms with four; Specifically; The lower part of four wooden forms is bound round in the mouth word of groined type central authorities that cover is clamped on four lower floor's reinforcing bars, and four lower floor's reinforcing bars are fixed with the welding of split heads muscle;
E, set up the side template of concrete foundation;
The concrete on f, disturbing concrete basis after treating that concrete is stiff and reaching design strength and require, is pulled down four wooden forms, the anchor (bolt) hole of reserving on the concrete foundation.
There are following defective in the concrete foundation that is used for fixing plant equipment and the job practices thereof of prior art: 1, after the stiff moulding of concrete foundation; Four wooden forms of need dismantling; But wooden form is tightened by the concrete anchoring; Wooden form is difficult to tear open even do not tear open, so very inconvenience even can influence the construction quality of subsequent handling; 2, in the disturbing concrete process; Concrete vibrator meeting vibrated concrete; Concrete impacts wooden form and fixedly eight reinforcing bars and the split heads muscle of wooden form under the effect of vibrator, and that upper and lower eight reinforcing bars of wooden form, hoop cover wooden form weld the split heads muscle of lower floor's reinforcing bar in addition is all firm inadequately, easily by the concrete impact and displacement deformation; Cause the last anchor (bolt) hole offset that forms, size to change, can not satisfy the pinpoint needs of plant equipment; 3, only be to be anchored in the concrete of concrete foundation with the fixing stone bolt of plant equipment; This anchoring is exactly in fact the bonding between the concrete; Its intensity and bearing capacity are all undesirable, main equipment when vibrations operation, can relax even destroy stone bolt; Make mechanical fixation not firm, have potential safety hazard.
Summary of the invention
The technical problem that the present invention will solve is a kind of easy construction to be provided, can accurately to locate plant equipment and the solid and reliable concrete foundation that is used for fixing plant equipment.
