Abstract
The utility model relates to a positioning device for construction, in particular to a positioning device of pile heads of bored concrete pile combined foundations, wherein the positioning device solves the problems that when pile heads of existing bored concrete pile combined foundations shift seriously, equipment will be difficult to install and project quality is affected. The positioning device of the pile heads of the bored concrete pile combined foundations comprises a rectangular frame, a plurality of parallel connection boards fixed to the rectangular frame are uniformly arranged in the rectangular frame, formwork sleeves are fixed to the joints of the rectangular frame and the connection boards, a plurality of thread sleeves are fixed to the outer wall of the rectangular frame, screw rods penetrate through the thread sleeves, a supporting board is arranged at the bottom of each screw rod, a plurality of jackscrews arranged in the radial direction penetrate through the formwork sleeves, and the inner ends of the jackscrews are connected with pile head formworks. The positioning device of the pile heads of the bored concrete pile combined foundations is reasonable and reliable in structural design, can not only guarantee accuracy and fastness of the positions of the pile heads but also have the advantage of controlling the scale heights of the pile heads of the bored concrete piles, and has the advantages of being convenient to manufacture, strong in universality and low in cost.
Description
Technical field
The utility model relates to construction and uses positioner, is specially a kind of cast-in-place concrete pile combination foundation pile crown positioner.
Background technology
The cast-in-place concrete pile combination foundation, be comprised of several cast-in-place concrete piles, is generally equipment Foundations.The characteristics of this combination foundation are that the stake top is without cushion cap, equipment directly is placed in stake top mouthful, every pile is all the basic fulcrum of an independent equipment, must be accurately according to the physical dimension of each pile position in equipment installation requirement combination foundation, and the stake top mark is high must be consistent.
When practice of construction, it (is highly the 20-30cm left and right that the concrete of the pile crown part that ground is above needs just can build after formwork supporting plate, template is generally made of PVC), but this segment template is fixing more difficult, during concreting, under the effect of vibrator, the pile crown concrete has larger displacement, when displacement is serious, the equipment not only caused is installed difficulty, also can, due to pile deflection, make the perpendicularity deviation of basic pile body surpass the construction inspection rules permissible value, so that cause the mass defect of stake itself, thereby affect workmanship.
Summary of the invention
The utility model easily causes when serious equipment that difficulty is installed and affects the problem of workmanship in order to solve existing concrete castinplace pile combination foundation pile deflection, and a kind of cast-in-place concrete pile combination foundation pile crown positioner is provided.
The utility model is to adopt following technical scheme to realize: cast-in-place concrete pile combination foundation pile crown positioner, comprise rectangular shaped rim, in rectangular shaped rim uniform be provided with some be parallel to each other and with the fixing junction plate of rectangular shaped rim, the infall of rectangular shaped rim and junction plate is fixed with the template sleeve, the rectangular shaped rim outer wall is fixed with some screw shells, be installed with screw mandrel in screw shell, the bottom of screw mandrel is provided with supporting plate, is installed with some radially the setting and the inner jackscrew be connected with the pile crown template on the template sleeve.
During operation, by regulating jackscrew, the pile crown template is carried out fastening, guaranteed that the pile crown concrete is not subjected to displacement, another effect of jackscrew is to regulate piles with different footpath pile crown template; By regulating screw mandrel, the horizontal level of control rectangle frame, overcome when existing concrete castinplace pile combination foundation pile deflection is serious the problem that easily causes equipment installation difficulty and affect workmanship simultaneously.
The utility model reasonable in design is reliable, can not only guarantee the pile crown position accurately firmly, and there is the filling pile head of control absolute altitude, have advantages of that easily manufactured, highly versatile and cost are low.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The structural representation that Fig. 2 is template sleeve place in Fig. 1.
In figure: 1-rectangular shaped rim, 2-junction plate, 3-template sleeve, 4-screw shell, 5-screw mandrel, 6-supporting plate, 7-pile crown template, 8-jackscrew.
The specific embodiment
Cast-in-place concrete pile combination foundation pile crown positioner, comprise rectangular shaped rim 1, rectangular shaped rim 1 interior uniform be provided with some be parallel to each other and with the fixing junction plate 2 of rectangular shaped rim 1, rectangular shaped rim 1 is fixed with template sleeve 3 with the infall of junction plate 2, rectangular shaped rim 1 outer wall is fixed with some screw shells 4, be installed with screw mandrel 5 in screw shell 4, the bottom of screw mandrel 5 is provided with supporting plate 6, is installed with some radially the setting and the inner jackscrew 8 be connected with pile crown template 7 on template sleeve 3.
In specific implementation process, every limit of rectangular shaped rim 1 and junction plate 2 all adopt square type cold-bend hollow profiled bar to make, and the joint of holding frame 1 adopts the clamping plate docking to connect.
