Abstract
The utility model relates to a formwork special for a square foundation bolt preformed hole. The formwork comprises a formwork body, the formwork body is a square formwork body defined by eight steel plates, the lateral edges of the eight steel plates are connected in an end-to-end mode, every two adjacent steel plates are hinged through a hinge shaft, the total number of the hinge shafts is eight, a base plate is arranged at the lower end of the formwork body, at least two layers of nuts are arranged in the square formwork body in the height direction of the formwork body, the two layers of nuts are connected through screws, the nuts and the formwork body are connected through four connecting rods, one end of each connecting rod is hinged to the corresponding nut, the other end of each connecting rod is hinged to the corresponding hinge shaft, and the four connecting rods and the eight hinge shafts are hinged at intervals. By means of the formwork, the square formwork capable of inwards contracting is designed; the formwork is of a square structure when being opened and can be used for forming the square foundation bolt preformed hole, after the square foundation bolt preformed hole is completely formed and the formwork disassembling requirement is met, the formwork can contract to be taken out from the preformed hole, the problem that an existing formwork cannot be disassembled easily is solved, the formwork can be repeatedly used and is rapid and convenient to assemble and disassemble, and manpower and material resources are greatly saved.
Description
technical field:
The utility model belongs to equipment installation Technology field, is specifically related to a kind of square anchor bolt box dedicated templates.
background technology:
At present, when some industrial and mining enterprises' equipment are installed, need the reserved anchor bolt installation hole in workshop in advance, reserved anchor bolt installation hole is mostly square opening, along with the development of industrial equipment, it is more and more, also increasing, dark that equipment is installed required reserved anchor bolt installation hole.The method of existing reserved anchor bolt installation hole generally has two kinds: the one, adopt not re-usable square wooden form, square wooden form is erected to setting, because the anchor bolt installation hole that existing equipment needs is more, install square wooden form, need to expend a large amount of man power and materials, also taken the plenty of time, and, because reserving hole inner space is less, remove square wooden form more difficult, most destructivenesses that adopt are removed, and exist and much cannot remove or remove sordid situation; The 2nd, adopt the suitable pvc pipe of diameter, this kind of situation because of easy construction more common, although can reasonable stripping, because reserved stone bolt hole is circle, and hole wall is smooth, directly affects the fastening effect of stone bolt; And, the impurity such as the floating ash existing in the reserving hole of above-mentioned two kinds of method settings, wood chip all cannot be cleared up, and from long-term site operation situation, pre-embedded anchoring bolts bottom need be worn in the hole of round steel, loaded down with trivial details because constructing, seldom have on request and to make, this has all directly affected the quality that equipment is installed, for serious potential safety hazard has been buried in the use of equipment.
utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of square anchor bolt box dedicated templates, it is a kind of square template that can inwardly shrink of design, it when this template struts, is tetragonal structure, can be used for the setting of square anchor bolt box, setting completed and reach after form removal requirement for preformed hole, this template is collapsible, then in preformed hole, take out, thereby solve existing template and be difficult for the problem of removing, and the utility model is reusable, and install, remove convenient and swift, manpower and materials have greatly been saved, adopt square structure, can not affect the fastening effect of stone bolt.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that
A kind of square anchor bolt box dedicated templates, wherein: comprise template, base plate, connecting rod and screw rod, the square template that described template is joined end to end and surrounded by eight block plate sides, and two adjacent block plates are hinged by jointed shaft, totally eight jointed shafts, template lower end is provided with base plate, short transverse along template in square template is provided with at least two-layer nut, two-layer nut connects by screw rod, nut is connected by four connecting rods with template, one end and the nut of connecting rod are hinged, the other end of connecting rod is hinged on jointed shaft, and four connecting rods and eight jointed shaft intervals are hinged.
Further, described base plate inner side is fixed with the round steel of bending.
Further, described screw rod is T-shaped screw rod, and its upper end is provided with handle.
The beneficial effects of the utility model are:
1, the utility model is a kind of square template that can inwardly shrink of design, it when this template struts, is tetragonal structure, can be used for the setting of square anchor bolt box, setting completed and reach after form removal requirement for preformed hole, this template is collapsible, then in preformed hole, take out, thereby solve existing template and be difficult for the problem of removing, and the utility model is reusable, and install, remove convenient and swift, greatly save manpower and materials, adopted square structure, can not affect the fastening effect of stone bolt.
2, the utility model has well improved the condition of labor that installation was laid, and removed, cleared up to equipment, makes equipment fitting operation and construction quality be improved and ensure.The utility model can repeatedly recycle, and provides cost savings, and has improved production efficiency.
