Abstract

The utility model relates to an installation positioning and fastening component of a concrete wall template and comprises a reach going through a wall. The utility model is characterized in that the reach consists of a central screw arranged inside the wall, a threaded sleeve which connects with the two ends of the central screw, an outer screw arranged on the outer end of the threaded sleeve, and a keel pressure pad which is sleeved on the outer screw through a middle through hole, as well as a locknut which is jointed on the outer end of the outer screw. The component has the advantages of novel conceive, simple techniques, low cost and convenient promoting and application, and is propitious to assembles and disassembles handled by users, thus enhancing the working efficiency, in addition, the utility model can be repeatedly used without causing waste to reduce the cost of the project, thereby having greater application development prospects.

Description

Concrete wall form installing and locating tightens up assembly

Affiliated technical field

The utility model relates to a kind of concrete wall form installing and locating and tightens up assembly.

Technical background

At present, the main member of the installing and locating device for fastening of concrete wall form is the long bolt of consistent body through walls and both sides Template Location frame thereof, after concrete wall forms and removes construction formwork, construction corps must excise the both ends of every long bolt one by one, so not only waste time and energy, but also cause the waste of the both ends screw rod of cutting-out, thereby increased the spending of construction costs.

Summary of the invention

The utility model mainly provides a kind of concrete wall form installing and locating to tighten up assembly, and this assembly not only helps user's assembly and disassembly of constructing, and reusable, does not cause waste.

The utility model is to constitute like this: it comprises the coupling bar that runs through body of wall, it is characterized in that: described coupling bar comprises the middle part screw rod of being located in the body of wall, be connected in the swivel nut at screw rod two ends, middle part and be connected in external screw rod on the swivel nut outer end, be placed in the keel pressing plate on the external screw rod and be connected in locking nut on the external screw rod outer end through the middle part through hole.

Above-mentioned swivel nut body is tapered, its big termination toward the outer side, the internal thread extension at middle part, big termination is regular polygon nut type (in order to the box spanner dismounting), the periphery of this extension is provided with the taper skirt section of swivel nut body; Both sides, described pressing plate two ends have curved portions; In addition, described middle part screw rod tightly is with flashing.

Tighten up assembly than existing concrete wall form installing and locating, the utility model is novel, and technology is simple, and is easy to utilize; This assembly helps user's assembly and disassembly of constructing, and has improved operating efficiency effectively, and it is reusable in addition, can not cause waste, has reduced construction costs.

The specific embodiment

Below just introduce concrete device of the present utility model and working condition in conjunction with the accompanying drawings:

Embodiment one:

With reference to Fig. 1, present embodiment comprises the coupling bar that runs through body of wall, described coupling bar comprises the middle part screw rod of being located in the body of wall 1, be connected in the swivel nut 2 at screw rod two ends, middle part and be connected in external screw rod 3 on the swivel nut outer end, be placed in the steel pipe keel pressing plate 4 on the external screw rod and be connected in locking nut 5 on the external screw rod outer end through the middle part through hole.In addition, described middle part screw rod tightly is with flashing 9, and both sides, steel pipe keel pressing plate two ends have the curved portions 8 in order to the fastening keel.

With reference to Fig. 5-6, swivel nut body of the present utility model is tapered, its big termination 6 toward the outer side, the internal thread extension at middle part, big termination is regular polygon nut type 7 (in order to the box spanner dismounting), the periphery of this extension is provided with the taper skirt section of swivel nut body.

With reference to Fig. 2, during work, earlier flashing 9 is enclosed within the centre of middle part screw rod 1 in order, again that the small end head of two swivel nuts 2 is inside, be inserted in middle part screw rod two ends respectively and regulate and screw by the working size of concrete wall thickness degree; Then two external screw rods 3 are inserted in template behind the big termination of precession swivel nut respectively, load onto steel pipe keel and keel pressing plate 4 afterwards successively, and screw with locking nut 5, the curved portions 8 that both sides, steel pipe keel pressing plate two ends have can the fastening keel.Pour concrete into, behind concrete wall formation and stripping, the taper swivel nut can be pulled down together with external screw rod, only surplus middle part screw rod is stayed in the concrete wall.External screw rod is reusable like this, not only convenient construction dismounting but also can not cause waste.

Embodiment two:

With reference to Fig. 3,5,6, the pressing plate 4 of present embodiment is wooden keel pressing plate, and all the other specifically install with embodiment one.

With reference to Fig. 4, during work, the keel that present embodiment uses are wooden center bar keels, during installation, but two portions of holding level with both hands of pressing plate are affixed on keel and screw just fastening keel, make its difficult drop-off; All the other specific embodiment are with embodiment one.

The utility model is novel, and technology is simple, and is with low cost, easy to utilize; This assembly helps user's assembly and disassembly of constructing, and has improved operating efficiency effectively, and it is reusable in addition, can not cause waste, has reduced construction costs, has bigger application development prospect.
