Description
Technical Field
The invention relates to a cast-in-place mould for pouring a building bridge upright post.
Background
In the construction of large buildings and bridges, concrete columns (namely bearing columns) with larger diameters are often required to be poured; the existing pouring mode is that a mould for accommodating concrete is built on the ground, the outer side of the mould is supported through a steel rod, the vertical state of the mould is maintained, then the concrete is poured, the mould is vibrated, and after the mould is dried, the mould is removed.
In the above operation steps, the steel rod for external support is point-contacted with the mould, and because the poured concrete is large in amount, when the mould is unstable, the point contact between the mould and the steel rod can cause the mould to be punctured, and finally, the support fails, the mould collapses, and great potential safety hazards exist.
Based on the problems, the cast-in-place mould for pouring the building bridge upright post capable of being stably placed is designed.
Disclosure of Invention
The invention aims to solve the technical problem of providing a cast-in-place mould for pouring a building bridge upright post capable of realizing stable placement.
In order to solve the problems, the invention adopts the following technical scheme:
a cast-in-place mould for pouring a building bridge upright column comprises two templates which can be spliced and assembled, wherein the templates are made of common carbon structural steel plates, and the wall thickness is 8 mm-22 mm; before pouring, an oil film needs to be brushed inside the template, or a plastic film is used for covering, so that later-stage demolding is facilitated; the two templates are combined to form a mold cavity for pouring concrete, arc-shaped reinforcing plates are welded on the outer walls of the templates, two ends of each reinforcing plate are bent to form lug plates, a bolt is assembled between the two lug plates, and the two templates are assembled after the bolt is tightened; a plurality of reinforcing plates are arranged in parallel up and down; a plurality of arc-shaped positioning grooves are annularly distributed on the outer side of the reinforcing plate, a plurality of vertical rods are assembled on the outer side of the template through the positioning grooves, threaded holes are formed in the outer walls of the vertical rods, an arc-shaped plate is installed on the outer wall of each vertical rod, a bolt is matched between the arc-shaped plate and the threaded holes, and a nut is matched after the bolt penetrates through the arc-shaped plate; the outer wall department of arc is provided with the mounting panel, the mounting panel level sets up vertical axis has been alternate in the mounting panel, has beaten into on ground and has had the bolt cover, the lower extreme screw in of vertical axis to in the bolt cover, be equipped with a plurality of clamping sleeves on the vertical axis, every mounting panel is by two from top to bottom the clamping sleeve is spacing, the outer wall department screw in of clamping sleeve has the screw, the screw in back supports vertical axis.
Preferably, after the two modules are spliced, a V-shaped clamping groove is formed at the position of a joint, a rubber sealing strip is arranged in the V-shaped clamping groove formed by combination, and the sealing strip is extruded and deformed; by the structure, leakage can be avoided when concrete is poured.
Preferably, a steel cable is assembled between the outer parts of the vertical rods and spirally wound on the outer parts of the vertical rods; a rib plate is arranged between the ear plate and the reinforcing plate; the steel cable can exert a tightening force between many vertical rods, will originally until exerting outside pressure's vertical rod in the outside alone and forming a whole, exert the power of a whole adduction, avoid the seam position department of template to take place the expansion seepage.
Preferably, an annular clamping groove is formed in the outer wall of the vertical rod, and the steel cable is clamped into the annular clamping groove when being spirally wound; when the vibrating bar is used for vibrating concrete, vibration force is transmitted to the formwork, and the steel cable is possibly changed in vertical position, so that the pressing force applied to the vertical rod is inaccurate in position. Therefore, the annular clamping groove is designed, after the steel cable is tightened, the steel cable is clamped into the annular clamping groove, and the position of the steel cable is prevented from being changed vertically.
Preferably, the positioning groove is matched with the vertical rod, and the radian of the positioning groove is not more than 1 pi; vertical pole adopts circular member, and its and constant head tank cooperation back, the part is the outside of protrusion to the reinforcing plate, consequently when the assembly steel cable, through vertical pole contact steel cable, owing to be circular, its anti deformability is stronger.
Preferably, a rubber stop washer is sleeved on the bolt and acts between the arc-shaped plate and the nut.
The invention has the beneficial effects that:
1) the device is provided with the reinforcing plate on the outer side of the template, and the structural strength of the template is increased in the circumferential direction through the reinforcing plate;
2) in the device, a plurality of vertical rods distributed annularly are adopted, the position of the vertical rods is determined through the matching of the vertical rods and the positioning grooves, each vertical rod is in contact with a plurality of reinforcing plates, the contact area is large, the contact points are more, the contact force is more uniform, and the damage caused by single-point support is avoided;
3) the vertical rods on the outer side are supported through the matching of the arc-shaped plates and the support plates, the using number of the support plates can be properly selected according to the height of the template, and the position of the support plates is determined through the matching of the vertical shafts and the bolt sleeves; compared with the oblique support of the steel rod, the device has the advantages that the support plate is matched with the vertical shaft, so that the occupied area is smaller, and the requirement on the position is smaller;
4) the steel cable is spirally wound among the vertical rods, so that tightening is realized, and expansion leakage at the joint of the die is avoided;
5) the structure of this device is comparatively simple, and the cost is comparatively cheap, is fit for using widely.
