Abstract
The utility model relates to a wall tie bar pre-embedded positioning thread sleeve including a cylindrical sleeve body, inner threads are arranged in the inside of the sleeve body, and the positioning thread sleeve is characterized in that two or more than two insert nails are connected at one end of the threaded opening of the cylindrical sleeve body of the wall tie bar pre-embedded positioning thread sleeve. The positioning thread sleeve is simple in structure and is easy to fix compared with the threaded fixing method in the prior art, when a wood template is detached, a wood template structure cannot be damaged, the circulated use of the wood template can be realized, thereby saving resources and saving a lot of manpower as well, and improving the work efficiency.
Description
Technical field
The utility model relates to a kind of positioning thread insert, is specifically related to the pre-buried positioning thread insert of a kind of wall tie bar.
Background technology
Building masonry wall and post are the important vertical supporting members of building, and in order to strengthen being connected between all kinds of masonry panels and reinforced concrete beam and post, code requirement will arrange tension rib between brick wall and reinforced concrete beam and post and body of wall.The general employing of wall tie bar is directly embedded in wall column concrete structure and two kinds of modes of later stage bar planting.Directly pre-buried tie bar is a kind of is to offer hole on wall column wooden form, steel tie is fixed on concrete structural column on reinforcing bar through hole, concreting again, but offering hole in template causes damage to template, affect template and has enough to meet the need and use and expend man-hour; Another kind is by being fixed on wall column rebar surface after tension rib bending, after form removable, manually tension rib is peeled off from wall column concrete, not only time-consuming, and wall column structure is caused to damage.Above way all can cause pre-buried tie bar bending, straightening difficulty while building by laying bricks or stones, affect building wall quality, later stage bar planting simultaneously need to be holed on steel concrete wall column, adopts organic adhesive by tension rib and wall column structural adhesive bonding, and the affected factor of bonding strength is many, durability is not high, difficulty of construction is larger, and cost is higher, and rebar-planting quality is difficult to guarantee.
For fear of the problems referred to above, now adopt a kind of built-in turnbuckle, built-in turnbuckle is fixed in concrete structural wood template, when concrete structural column, built and removed after wooden form, built-in turnbuckle embeds in concrete structural column, in swivel nut, be provided with the reinforcing bar that internal thread can be used for screwing in the good screw thread of rolling in advance, existing built-in turnbuckle structure comprises column body, body inside is provided with internal thread, internal thread opening one end is provided with cylindrical base, on base, have tapped through hole, during use, adopt screw to be fixed on wooden form.Yet, not easy to operate and workload is large when this swivel nut is installed, consuming time very long, while removing wooden form, still can destroy wooden formwork structure
,wooden form cannot reuse because damaging, and causes a large amount of wastes of timber.
Summary of the invention
The utility model improves the problems referred to above, and the technical problems to be solved in the utility model is to make wall tie bar built-in turnbuckle easier for installation, when dismounting wooden form, can guarantee that wooden form is not damaged, to realize recycling of wooden form.
Specific embodiments of the present utility model is: the pre-buried positioning thread insert of a kind of wall tie bar, comprise column body, described body inside is provided with internal thread, and the pre-buried positioning thread insert column of described wall tie bar body screw thread openings one end is connected with two or more plug pins.
Further, described plug pin and swivel nut are welding or riveted joint.
Further, described cylindrical sleeve external surface has tapered flanges along its length.
Compared with prior art, the utlity model has following beneficial effect: the utility model cylindricality swivel nut inside is provided with internal thread can conveniently insert reinforcing bar, column body is connected with two or more plug pins in screw thread openings one end, described in during use, plug pin can directly insert wooden form, easier for installation than traditional screw thread fixing means, also it is very simple when wooden form is pulled down, can not destroy wooden form overall structure, saved a large amount of manpowers, when economizing on resources, also saved a large amount of manpowers, increased work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structure preburied positioning device structural representation.
Fig. 2 is positioner working state schematic representation.
Fig. 3 is the utility model structure preburied positioning device sectional view.
Fig. 4 is for screwing in the structural representation after steel tie.
in figure: 1-column body, 2-plug pin, 3-concrete structural column, 4-wooden form, 5-reinforcing bar, 6-internal thread.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Fig. 1～4, the pre-buried positioning thread insert of the utility model wall tie bar comprises column body 1, column body 1 inside is provided with internal thread 6 can conveniently insert reinforcing bar, and column body is connected with two or more plug pins 2 in screw thread openings one end, and plug pin 2 can directly insert wooden form.Plug pin 2 is that welding or riveted joint etc. are fixedly connected with column body 1, and described body 1 and plug pin 2 materials are cast iron.
During use, first positioning thread insert 1 is followed closely on wooden form 4, be poured into afterwards concrete and form concrete structural column 3, until concrete structure, live 3 and remove wooden form 4 after dry, can in the screw of pre-buried positioning thread insert, insert with the externally threaded reinforcing bar 5 that matches with swivel nut internal thread after removing wooden form.Described cylindrical sleeve external surface has tapered flanges along its length, can increase the resistance of body and concrete column, to improve the steadiness of implanting reinforcing bar.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
Claims (3)
