Abstract

The utility model discloses a mold supporting structure for a concrete foundation hole of a large device. The mold supporting structure comprises prefabricated formworks, a plurality of iron pieces, bolts and waterproof adhesive tapes, wherein the prefabricated formworks are prefabricated concrete trapezoidal boards, a plurality of first screw holes are sequentially arranged in two side edges of each board, and the iron pieces are L-shaped connecting pieces. The prefabricated formwork includes four portions sequentially form a trapezoid column, each iron piece is arranged at the intersection angle position of every two adjacent prefabricated formworks, and the iron pieces and every two adjacent prefabricated formworks are fastened through bolts. The mold supporting structure for the concrete foundation hole of the large device adopts combined assembly of the prefabricated concrete formworks, achieves one-time mold supporting, a mold removal step is omitted, and the mold supporting structure has the advantages of being high in construction speed, low in labor intensity and low in construction cost and easily ensuring the construction quality.

Description

The formwork erecting structure in main equipment concrete foundation hole
Technical field
The utility model relates to Large Equipment Foundation technical field, the formwork erecting structure in especially a kind of main equipment concrete foundation hole.
Background technology
The foundation construction of prior art main equipment, especially in the foundation construction of the main equipment such as steel mill, cement plant, power plant, the concrete foundation preformed hole size of its equipment is larger, the degree of depth is darker, it is pre-buried that prior art adopts the wooden reserved cartridge of monolithic to carry out, and after concrete reaches some strength, wooden reserved cartridge removed; The problem existing is, difficulty of construction is large, especially the demoulding of preformed hole especially constructor feel very thorny thing, because wooden reserved cartridge easily absorbs water, particularly, in concreting process, template is under wet environment all the time, when concrete reaches demoulding requirement, template is imbibition, and deadweight strengthens, and to dismounting, has brought very large difficulty, in addition in preformed hole, mostly be up-small and down-big structure, template clip is inside difficult to take off, and the lighter causes the loss of doing over again, and severe one causes quality accident.
Utility model content
The purpose of this utility model is the formwork erecting structure in a kind of main equipment concrete foundation hole of providing for the deficiencies in the prior art, the utility model adopts concrete prefabricated form assembly assembling, disposable formwork, saved the operation of form removal, have that speed of application is fast, labour intensity is little, construction cost is low, and the advantage that easily guarantees of construction quality.
The concrete technical scheme that realizes the utility model object is:
The formwork erecting structure in a kind of main equipment concrete foundation hole, its feature comprises prefab form, ironware, bolt and adhesive waterproof tape, described prefab form is concrete prefabricated trapezoidal plate, in its plate, be furnished with reinforcing bar, edges of boards are provided with suspension ring, the two waist limits along plate are provided with several the first screws successively, ironware is " L " shape connector, its two ends are provided with the second screw: described prefab form is four, surround successively trapezoidal column, ironware is several, ironware is located at the angle of cut place of adjacent two prefab forms, bolt is fastening by ironware and adjacent two prefab forms through the second screw and the first screw, adhesive waterproof tape is pasted the seam crossing at adjacent two prefab forms.
The utility model adopts concrete prefabricated form assembly assembling, and disposable formwork, has saved the operation of form removal, has that speed of application is fast, labour intensity is little, construction cost is low, and the advantage that easily guarantees of construction quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model prefab form;
Fig. 3 is use view of the present utility model.
The specific embodiment
Consult Fig. 1, Fig. 2, the utility model comprises prefab form 1, ironware 2, bolt 3 and adhesive waterproof tape 4, described prefab form 1 is concrete prefabricated trapezoidal plate, in its plate, be furnished with reinforcing bar, edges of boards are provided with suspension ring 12, the two waist limits along plate are provided with several the first screws 11 successively, ironware 2 is " L " shape connector, its two ends are provided with the second screw 21: described prefab form 1 is four, surround successively trapezoidal column, ironware 2 is several, ironware 2 is located at the angle of cut place of adjacent two prefab forms 1, bolt 3 is fastening by ironware 2 and adjacent two prefab forms 1 through the second screw 21 and the first screw 11, adhesive waterproof tape 4 is pasted the seam crossing at adjacent two prefab forms 1.
The utility model is to use like this:
Consult Fig. 1, Fig. 2, Fig. 3,
A), the making of prefab form: first according to Large Equipment Foundation figure, the prefab form 1 that making thickness is 25mm, in prefab form 1, join reinforcing bar, the strength grade of concrete of prefab form 1 exceeds a grade (the minimum C25 of being not less than) than base concrete;
B), the transportation of prefab form: loose mail prefab form 1 is transported to job site and carries out assembling combination;
C), prefab form is assembled: get four prefab forms 1, surround successively trapezoidal column, ironware 2 is several, ironware 2 is located at the angle of cut place of adjacent two prefab forms 1, bolt 3 is fastening by ironware 2 and adjacent two prefab forms 1 through the second screw 21 and the first screw 11, is made into the cylinder mould of trapezoidal column; And paste adhesive waterproof tape 4 at the seam crossing of adjacent two prefab forms 1;
D), cylinder mould is in place: according to the position of the basic preformed hole of Large Equipment Foundation figure, put the outer contour of correction center line and cylinder mould, the suspension ring 12 with lifting appliance by prefab form 1 are by cylinder mould hoisted in position, correction;
E), cylinder mould is fixing with basis: after cylinder mould is in place, by the reinforcing bar of the distribution in basis, it is fixed, cylinder mould around groined type fixedly reinforcing bar must be welded and fixed with sole plate inner structure reinforcing bar; To local foundation structure reinforcing bar, can not meet while fixedly requiring, can suitably increase auxiliary reinforcement and be fixed;
F), concreting: first by the 1:2 cement mortar shutoff for surrounding of cylinder mould bottom; Before concreting, conscientiously check formwork seal situation, guarantee not spillage; Should be by cylinder mould temporary enclosed suitable for reading in concreting process, prevent that concrete from falling in a nib; Cylinder mould around should water and smash symmetrically, prevents disposable blanking too much or eccentric force, causes a mould skew; In base concrete casting process, should check at any time the position of a mould, guarantee that position is accurate.
