Abstract
The utility model discloses a device for positioning and anchoring templates on a beam, a column and a shear wall. The device comprises a pull rod used for being connected with the templates, wherein screw heads with threads are arranged at the two end parts of the pull rod, and connected with fastening bolts via the threads; the templates are matched and fixed with the pull rod via the fastening bolts; holes for allowing the fastening bolts to be inserted are formed on the templates; concrete is wrapped and poured outside the pull rod to form a pull rod cement stick; counter bores are formed at the two ends of the cement stick; the screw heads at the two ends of the pull rod are positioned in the counter bores; the pull rod cement stick is circular or square; each of the fastening bolt comprises a screw rod, a thread hole for allowing the screw head at the end part of the pull rod to be screwed into and connected is formed at one end part of the screw rod, and a rotating handle is arranged at the other end part of the screw rod; and a bolt cap is further arranged in the middle of each fastening bolt. The device provided by the utility model is used for fixing the templates on the cement beam, the cement column and the cement shear wall in cement structure construction, can effectively prevent the templates from cripling during the concrete structure construction, and greatly reduces the stable support in the prior art when the templates are supported in the structure.
Description
Technical field
The utility model relates to the construction formwork application, and specifically, the utility model relates to a kind of beam column shear wall formwork positioning and anchoring device.
Background technology
In the building trade, during the concrete structure construction, need to use pull bar add fixed bit to template, when preventing the concrete pouring, the mould phenomenon that expands the template distending appears in powerful lateral pressure; It is at present most of that what adopt is that single monolithic screw rod is reinforced from the form that is embedded in the PVC sleeve pipe of building the thing, build completion after, also need plastic pipe be tripped out and shutoff is carried out in left hole; Seepage appears in the halfway meeting of shutoff, in addition, and owing to the reason of building; It is also more time-consuming to trip out screw rod; And also rise to come out sometimes, must adopt the burning tapping to use stripping, have enough to meet the need untimely and lost labor and material.
Summary of the invention
The purpose of the utility model provides a kind of need not trip out and back Template Location anchor device that forms as one with the concrete structure that finishes of constructing.
For realizing above-mentioned utility model purpose; The technical scheme of the beam that the utility model provided, post and shear wall formwork positioning and anchoring device is: a kind of beam, post and shear wall formwork positioning and anchoring device; Comprise that one connects the pull bar of template; The pull bar both ends are the silk head with screw thread, with screw thread silk head respectively through the fastening bolt that has been threaded, template is through fastening bolt and pull bar matching and fixing; Offer the hole that supplies fastening bolt to insert on the template.
The pull bar outer wrap has been built concrete, is configured as the pull bar cement rod, and the cement rod two ends are provided with counterbore, and the silk head at pull bar two ends is positioned at counterbore.The pull bar cement rod is circular or square.
Fastening bolt comprises a screw rod, and an end of screw rod supplies tie rod end silk head to screw in the screwed hole that connects, and the other end of screw rod is provided with a rotary handle.The middle part of fastening bolt also is provided with a nuts.
The beneficial effect of the utility model is:
The utility model is used for concrete beam, post, shear wall etc., and concrete structure is fixed the anchorage element of two side templates in work progress.Be characterized in; Pull bar is to be tensile materials with the reinforcing bar.The length and the diameter of reinforcing bar are confirmed by the length of pull bar.Reinforcing bar outerwrap concrete is made circular or square concrete rod.The length of concrete rod equates with the isostructural out-to-out of beam column shear wall.Can effectively eliminate concrete structure and in work progress, produce template cripling phenomenon.Simultaneously; Steadiness when reducing the structure formwork in a large number supports.
Description of drawings
Fig. 1 is the utility model mounting structure sketch map;
Fig. 2 is the structural representation of fastening bolt among Fig. 1.
Be described in detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
The specific embodiment
Fig. 1 is the utility model mounting structure sketch map; Fig. 2 is the structural representation of fastening bolt among Fig. 1.The utility model mainly is the Template Location anchor device that is used for beam, post and shear wall; Comprise that one connects the pull bar 2 of template 1; Pull bar 2 both ends are the silk 21 with screw thread; With screw thread silk 21 respectively through the fastening bolt 3 that has been threaded, template 1 is through fastening bolt 3 and pull bar 2 matching and fixing; Offer the hole 11 that supplies fastening bolt 3 to insert on the template 1.
Wherein, pull bar 2 outer wrap have been built concrete 22, are configured as the pull bar cement rod, and the cement rod two ends are provided with counterbore 23, and the silk 21 at pull bar 2 two ends is positioned at counterbore 23, and the pull bar cement rod be circular or square, and present embodiment is a circle.
Wherein, fastening bolt 3 comprises a screw rod 31, and there is the screwed hole 32 that supplies the 21 screw-in connection of tie rod end screw thread silk an end of screw rod 31, and the other end of screw rod 31 is provided with a rotary handle 33, and the middle part of fastening bolt 3 also is provided with a nuts 34.
During installation, rotary handle 33 rotations through fastening bolt 3 one ends apply strength, make an end of fastening bolt 3 get into threads 21 of hole 11 and pull bar 2 on the template 1 and are rotatably connected, and two ends all reach fixation through fastening bolt.Wherein, the diameter of pull bar cement rod is greater than the hole on the template 1 11, when so carrying out the concrete structure construction; Concrete can not omitted out outside the template, after construction finishes, can directly remove fastening bolt 3 and template 1; Cement rod and concrete structure become one; Ensure structural strength, and exempted the dismounting operation, avoided the generation of template cripling phenomenon.After dismounting finishes, can carry out simple cement filling and repairing for the surperficial counterbore 23 of pull bar cement rod.Pull bar 2 can adopt the reinforcing bar material, and the length and the diameter of reinforcing bar are confirmed by the length of pull bar.The length of concrete rod equates with the isostructural out-to-out of beam column shear wall.
The utility model also can have other variation; Know like those skilled in the art; The foregoing description only plays the exemplary role in the above-mentioned utility model protection scope; Concerning those of ordinary skills, in the protection domain that the utility model limited, also have a lot of conventional distortion and other embodiment, these distortion and embodiment will be within the protection domains that the utility model awaits the reply.
