Description

Fastener with a reinforcement fastening part

The present invention relates to a kind of fastener with a reinforcement fastening part.More particularly, the present invention relates to a kind ofly be suitable for use in the concrete moulding with framework and fastener other similar item, that have a reinforcement fastening part.

Up to now, the U-shaped fastener (prior art) that the is called the U-shaped folder shown in Figure 6 concrete moulding framework that is widely used in being formed from steel.This fastener is used for supporting securely and is that to live moulding admittedly be very easily with the required part at the back side of framework, and it is to be made by the bar that lower mild steel of a kind of price or medium carbon steel are made.

When needs were constructed a bigger concrete structure, in a lot of situations, it was to use in a lot of modes that are connected with each other that single weight is about 10 to 30 kilograms framework unit.In this case, combine as the easy strength deficiency of holistic framework.Therefore, in a lot of situations, a pair of reinforcement that will be such as steel pipe is parallel be arranged on across several to the back side of tens frameworks.

Usually, the moulding that is formed from steel is assembled with two kinds of methods haply with framework and is fixed together, and it depends on the method for fastening moulding with framework and reinforcement.But here, moulding is identical with framework fastener and securing method.

First method is to finish the widely used method of this operation, according to this method, described moulding is imperforate with the panel of framework, be located in each moulding with each the hole A in framework with use, one tabular separator is folded in two moulding with between the framework, and fixes by each accessory that passes the hole.In this case, each reinforcement is fastening near coming in each framework endoporus A, the independent hole B that bores a hole with a securing member being plugged in one.But this method has a shortcoming, that is, because its structure can not be fastened on each reinforcement on the one coaxial extension of described separator.

According to second method, each hole C is formed on each moulding with in each panel of framework, the end of one shaft-like separator is plugged in hole C, the C of two panels, the outside of metal, rod-shaped system fastener from each panel is screwed in the end of thread of described separator, thereby fasten each reinforcement.This method has an advantage, that is, each reinforcement can be fastened on the coaxial extension of described separator.But, because each hole is formed in each panel, therefore, after concrete curing, understanding formation is not desirable uneven phenomenon, thereby has reduced the fineness of finished surface, and has shortened the application life (reusable number of times) of steel moulding usefulness framework.

In addition, be used for the steel moulding and require one to be used for the independent accessory of fastening each reinforcement, thereby be difficult to be secured on each reinforcement with traditional fastener of framework.Specifically, in higher place, and, must use three types part, promptly in those scaffolds complete narrow and small place of feeling unwell, U-shaped fastener, straight shaft-like securing member and the fastening packing ring of using, so that with using an independent securing member, each reinforcement is fixed in described steel moulding with on the framework, arduous operation is carried out in this requirement, so that these parts are correctly located, therefore make this operation become very difficult.

In addition, when in the through hole 40B, the 40B that a twist mode conventional fittings (metal tie rod) 201 (referring to Fig. 7) that is used for fastening each reinforcement are inserted the framework that stands vertically 40,40 shown in Figure 8, long side has a declining tendency under action of gravity, thereby has hindered described operation.

In Fig. 1, reinforcement fastening part 15 is cylindrical forms, and its top has screw thread (also can carry out hot pressing processing to it), and its root place be angle γ and β respectively with horizontal projection 20 and linear extension 11.Solid portion 5 of U-shaped system with a narrow orifice, and is attached thereto from linear extension 11 liftings with a lifting angle α (80 °≤α≤130 °) (γ and δ are almost 90 degree).The solid portion 5 of U-shaped system that has a narrow orifice has a central axis on the plane 6 that comprises horseshoe clamp face 5A, described horseshoe clamp face 5A comprises the center line of the central part of solid portion 5 of U-shaped system, lifting angle α is plane 6 and at an angle that comprises between the linear extension 11 on plane of center line of reinforcement fastening part 15, and at right angles intersect on described center line and plane 6.It is 85 °≤β≤110 ° that people it is desirable for reinforcement fastening part 15 and linear extension 11 folded angle β.This be because, when angle β spent less than 85, when solid portion 5 of the U-shaped system with an osculum was driven fully, reinforcement fastening part 15 was with over-tilting.On the other hand, when angle β surpasses 110 when spending, unless angle α reduces to some extent or the degree of depth that has a solid portion 5 of U-shaped system of a narrow orifice increases (this is infeasible) to some extent, reinforcement fastening part 15 is with over-tilting.Whether the scope of angle β mainly is convenient to processing on it is decided.

Importantly, as described in will giving hereinafter, from clamping the angle of a pair of

framework

40,40, horseshoe clamp face 5A must be arranged essentially parallel to horizontal projection 20.

When lifting angle α spends less than 80, with regard to that to clamp this to framework 40,40.On the other hand, when lifting angle α spent above 130, the clamping degree of depth reduced, and this just can not fully be clamped framework.Therefore, people wish that angle α is in the scope of 80 °≤α≤130 °.

The straight portion 10 that has the solid portion 5 of U-shaped system of a narrow orifice almost is parallel each other with 5c, and its gap 5D is slightly less than this thickness sum to framework 40,40 and described separator end 50A.Therefore, when with three blocks of plates (the end 50A of framework 40, separator, framework 40) when inserting in it because elastic deformation, so gap 5D is expanded.In this case, described three blocks of plates (being referred to as superimposed panel hereinafter) are pressurized on thickness direction.Owing to obtain based on the tensile stress of the reinforcement fastening part 15 of nut 27 and elastic washer 28 or the help of tensile stress, therefore, can be with described three members, that is, and framework.Separator has no with gap, firmly fixes and be in the same place with reinforcement.(referring to Fig. 1 and Fig. 2).

This is to finish by the method for the following stated.

Now see also Fig. 2,

label

60A and 60B show the rear board and the front panel of concrete wall.At first, one end 50A of separator 50 is folded between the

framework

40,40 of this

counter plate

60A, 60B, make

hole

40B, 50B and 40B (being referred to as stacked hole hereinafter) aligned with each other, and be that the horizontal projection 20 of solid accessory inserts in the described stacked hole the present invention.Usually, this is with a hammer, the horizontal projection 20 of direction (axis direction of horizontal projection) knocking of arrow X is realized in Fig. 1.

Horizontal projection 20 hammers are gone in the stacked hole up to its root.Then, as shown in Figure 1, with a hammer, towards almost perpendicular to the described solid portion of U-shaped system that has a narrow orifice of the direction knocking of the arrow Y of horseshoe clamp face 5A.Just, be that axis rotates reinforcement fastening part 15 towards the direction of arrow Z with horizontal projection 20, and become almost perpendicular to described horizontal direction or be about to become certain part of a concrete wall wall.Therefore, as shown in Figure 3, can be admittedly together with reinforcement 70 (being square pipe in this case) and the reinforcement 71 (being circular pipe in this case) that is right-angled intersection toward each other.And be in a kind of like this state: a reinforcement is on another reinforcement, and is and pressurized.Although Fig. 3 only shows a reinforcement (square pipe) 70,, can certainly use two parallel reinforcements (square pipe) 70.

And meanwhile, separator 50 extends through concrete 100 (also not pouring) and fuses (described two front panels are connected in the mode identical with above-mentioned rear board) with the coupling part with opposed two front panel 60B.Therefore, the framework of concrete moulding can be fixed together is I shape, and the reinforcement that is right-angled intersection can be firmly fastened to and be fixed in the outside, rear surface and the front surface outside of concrete wall.Repeat this operation, just can construct the framework of the moulding that assembles securely easily with big wall area.Reinforcement can be not to be right-angled intersection, and can otherwise be provided with according to wall thickness and wall area.Perhaps, can not use reinforcement in couples, employed each reinforcement can only be one (referring to Fig. 5).

After concrete solidifies, with the framework of removing nut 27 dismantling concrete moulding easily, carry, and reuse in next place.But each separator is still stayed in the described concrete wall.

Fig. 4 shows the reinforcement fastening part 15 of another embodiment of the present invention.Utilize a hammer, thump from direction W, one voussoir 18 is squeezed in the elongated hole 17 that is formed in the end 15B of reinforcement fastening part (two or more elongated hole normally, be used for adjusting fastening hammering), thus this terminal operation can be finished easily.

Annular knurl that can the formative gear shape on the ramp of voussoir 18.So just can be so that be solid more strong and powerful, and after voussoir 18 is fastened, be difficult for being removed.During dismounting, can use described hammer.Towards the direction opposite voussoir 18 of thumping with W.Adopt the reinforcement fastening part of this voussoir to be useful in very much in the not good project site of those operating environments.

With all purposes of implementing the present invention, can realize above to be mentioned, can solve the shortcoming of the twist mode tradition reinforcement securing member that preamble mentions and intrinsic problem.Just, the invention provides a kind of like this fastener, it has an all-in-one-piece reinforcement fastening part with it, and it helps to improve the operating efficiency in a dangerous narrow and small working environment, can also provide increased intensity with framework for the moulding of assembling.
