Abstract
Provided is a template concrete shear key, which is a combining body formed by connecting an inner end face of a cylindrical body having external filament and a large frustum face of a frustum body in a manner of butt joint. The diameter of the cylindrical body having external filament is equal to that of the large frustum face of the frustum body. The center of the cylindrical body having external filament and that of the frustum body are in the same line. The axial line of the combining body is provided with an installing hole for wall penetrating and rod pulling. The template concrete shear key is advantageous in that wall penetrating and rod pulling can be realized, and the problem that only horizontal pulling force can be borne can be resolved; the template concrete shear key can be used repetitively for multiple times, and thereby construction efficiency is improved and construction materials can be saved; the template concrete shear key can be widely applied in concrete casting of vertical members.
Description
Technical field
The utility model relates to fixedly auxiliary part of a kind of performance of concrete column confined construction auxiliary part, particularly a kind of performance of concrete column confined construction formwork.
Background technology
in the construction of bridge pier column concrete cast-in-situ, usually by wall-through pull rod drawknot template, in work progress, wall-through pull rod had both born horizontal pull, bear again vertical shear, and the diameter of wall-through pull rod is generally all smaller, under the effect of complicated power, may be because the excessive wall-through pull rod of vertical shear is cut off, cause construction to interrupt, for fear of this type of construction accident occurring, usually pre-buried shearing-resistant member before concreting, although pre-buried shearing-resistant member has solved the problem of sharing vertical shear that wall-through pull rod is born, but its working procedure is complicated, complete can't the taking-up of constructing had enough to meet the need use, construction cost is high.In order to save construction cost, after shearing-resistant member is completed the mission of its vertical shear that produces in bearing construction, can have enough to meet the need use, the utility model has designed a kind of to coordinate practical individual member---shear connector with hold-down nut, wall-through pull rod and exterior sheathing.
The utility model content
The purpose of this utility model is to provide a kind of template concrete shear connector, solve the existing built-in fitting of bearing vertical load in construction and can't have enough to meet the need use, the technical problem of complicated construction technique.
For achieving the above object, the utility model adopts following technical scheme:
A kind of template concrete shear connector, the cylindrical inner face of the outer silk of band and the auger table top of cone table of serving as reasons docks the assembly that forms, the equal diameters of the cylindrical diameter of the outer silk of described band and the auger table top of cone table, and the cylinder of the outer silk of band and the center of cone table on the same straight line, offer the installing hole of wall-through pull rod on the axis of described assembly.
Offer the installation groove on the cylindrical outer face of the outer silk of described band, described installation groove center line is by the center of the cylinder outer face of the outer silk of described band.
Described installation groove is rectangular channel, and its width is 6mm～10mm.
Described installing hole diameter is greater than the diameter of wall-through pull rod, and it is connected with the wall-through pull rod gap.
Compared with prior art the utlity model has following characteristics and beneficial effect:
Shear connector described in the utility model and wall-through pull rod, hold-down nut and exterior sheathing are used in conjunction with, the template construction load all can be delivered to it performance of concrete column confined, wall-through pull rod only bears horizontal pull and is not subjected to vertical shear, and pull bar and template concrete shear connector are stressed clear and definite.This template concrete shear connector can fall use repeatedly, can along with template together or independent the installation, compare with traditional disposable built-in fitting, flexible for installation, and greatly reduce cost.This template concrete shear connector can be used for common turning over and rises template, and can greatly improve efficiency of construction.
Shear connector described in the utility model its to insert concrete be partly frustum, both can be in work progress reliable shearing resistance be provided, again the taking-up of the complete shear connector of constructability.
Offer the installation groove on the cylinder outer face of shear connector described in the utility model, for peace, tear open and facilitate.
The utility model can be widely used in the concreting of vertical member.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural plan schematic diagram.
Fig. 2 is that the utility model uses state diagram.
Cylinder, 2-cone table, 3-installing hole, the 4-of the outer silk of Reference numeral: 1-band install groove, 5-wall-through pull rod, 6-hold-down nut, 7-template, 8-performance of concrete column confined.
The specific embodiment
Embodiment is referring to illustrated in figures 1 and 2, a kind of template concrete shear connector, the assembly that the auger table top docking of the inner face of the cylinder 1 that the band of serving as reasons is outer and cone table 2 forms, the equal diameters of the diameter of the cylinder 1 of the outer silk of described band and the auger table top of cone table 2, and the cylinder 1 of the outer silk of band and the center of cone table 2 on the same straight line, offer the installing hole 3 of wall-through pull rod 5 on the axis of described assembly.The diameter of the cylinder 1 of the outer silk of described band is got 52mm.Offer groove 4 is installed on the outer face of the cylinder 1 of the outer silk of described band, described installation groove 4 center lines are by the center of cylinder 1 outer face of the outer silk of described band.Described installation groove 4 is rectangular channel, and its width is 6mm～10mm.Described installing hole 3 diameters are greater than the diameter of wall-through pull rod 5, and it is connected with wall-through pull rod 5 gaps.The diameter region 26mm of described wall-through pull rod 5.The cylinder 1 of the outer silk of described band and cone table 2 adopt the casting of high-quality steel or cutting to form.
Using method of the present utility model is as follows:
At first, hold-down nut 6 of the position in corresponding wall-through pull rod hole welding on the lateral surface of template 7, then utilize tool wrench to snap in installation groove 4 on template concrete shear connector, and screw in template concrete shear connector in hold-down nut 6 and form the wall-through pull rod hole on template 7, the cone table 2 on template concrete shear connector is positioned at the rear pouring concrete inboard of template 7 at this moment; Then the inside and outside template of normal mounting, make inside and outside template fixing to form template system at the interior installation wall-through pull rod 5 of installing hole 3.
Concreting between inner formword and exterior sheathing afterwards, form first segment Dun Bi after concrete setting, template concrete shear connector will embed the pier pars intramuralis this moment, thereby can bear the local pressure that upper load that template concrete shear connector transmits applies, and reliable template shearing namely is provided.
Remove finally exterior sheathing and upper wall-through pull rod 5 thereof, this moment, template concrete shear connector can be removed separately, also can remove together with exterior sheathing, if exterior sheathing need not finishing, template concrete shear connector can not removed separately.This template concrete shear connector can fall use repeatedly, and is flexible, safe and reliable.
