Description

Connector

The present invention relates to a kind of connector, be used for mechanical connecting structure parts and so on the described feature of claim 1 preamble.

This connector for example disclosed in DE 100 26 769 A1.Wherein, in the pre-assembled scope, on each of two structure members to be connected and so on, to fix a coupling respectively and join half one with screw.For the syndeton parts, make coupling join half one and intermesh.For this reason, they have a centralizer that has wedge shape or taper engaged element.The inside that joins half one at coupling has been arranged the conduit Connection Element in addition, is used for water, combustion gas, electricity etc., like this, also can implement medium and connect when carrying out mechanical connection.Under the situation of heavy especially structure member such as building construction prefabricated component wall, Connection Element must bear very high load.Because the unevenness of floor is, following phenomenon may take place: in confined state, a whole wall is being born by two adjacent walls.When installing, prefabricated wall except this gravity, also can produce big inertia force and impact.Say in principle, the required time is installed play an important role.Because the complicated structure of known Connection Element, their plastics only allowable or cast aluminium are realized economic shaping, so be unappeasable to this requirement of mechanical supporting capacity.

Task of the present invention provides a kind of connector of high stability, and it can realize the assembling of connected structure member fast, and use particularly combines with disclosed connector among patent document DE 100 26 769 A1.

According to the present invention, above-mentioned task is solved by the described feature of claim 1.Coupling joins half one and has pipe fitting, and these pipe fittings can be plugged together each other because different cross sections are.Wherein, can for example adopt standardized steel quadrangle square tube.According to the present invention, " pipe fitting " this notion is applicable to that to all its cross sections the parts of vertical guiding all have same meaning, for example also comprise band steel, I-section bar, C-section bar or T-section bar assembly with pipe fitting, according to this, this shaped steel can certainly have a longitudinal seam corresponding to the type rail, perhaps can narrow down to one or several ear handle.Comprise groove cross section/spring cross section in addition, these cross sections by the recessed cutting of side so be applicable to a kind of vertical guiding.Rail system system or forging system can support this guiding character.

Each pipe fitting is tiltedly to arrange facing to the bearing surface of structure member.Each pipe fitting is overlapped each other fashionable, each structure member have one perpendicular to the Union Movement that is parallel to its bearing surface.The stroke that is inserted in is not subjected to coupling to join the restriction of half one, in case but structure member stop at once when contacting with its bearing surface.Coupling joins half one and so is placed on the structure member, makes that fixing the coupling that has the pipe fitting that is standing obliquely on that fixing structure member joins half one, and another structure member to be joined then has a pipe fitting down.Therefore, when engaging two structure members, can utilize the gravity of structure member to be joined.Be in tilted layout by this of pipe fitting, structure member is forced to guiding, and finally seamlessly gets up against each other with their bearing surface.With the sort of regulation have perpendicular to or the connector that is parallel to the direction of engagement of bearing surface compare, thereby following advantage is arranged: structure member does not need to be strained especially after engaging.If combining with disclosed connector in DE 100 26 769 A1, used the connector that the present invention is proposed, will obtain another advantage: the connector that the present invention proposes is bearing gravity and engaging force in engaging process and after engaging, disclosed connector is then unloaded in DE 100 26 769 A1, so they can design more weakly.The enforced guiding of the connector that proposes by the present invention, the connector that DE 100 26 769 A1 propose then can so relatively move, and makes their centralizer always can facilitate a kind of little balance exercise, combines with little power.

According to a kind of preferred construction form, the pipe fitting with less cross section has one to introduce lid.By consequent introducing inclined-plane, even under very inexact location condition, coupling joins half one and also can be easy to engage.This point is very important when connecting the wall of prefabricated building structure for example, this be because under a stable condition on crane very big wall spare must be engaged with dangling.

In order to make pipe fitting tilting on structure member, by the preferred construction form, coupling joins the base that half one has a wedge shape of for example making of plastics, in order to supporting tubular member.Coupling joins half one and is screwed on structure member.In order to realize from pipe fitting through the direct power stream of screw to each structure member, make head of screw cling to pipe fitting on the inboard of this structure member, and reach in this structure member by base always.

Be transverse to the connection of the direction of engagement of connector in order to proofread and correct two structure members, for example in order to compensate the purpose of the inexactness of being made condition restriction, a kind of form of structure that the present invention proposes has a correcting element between two pipe fittings, have to be transverse to pipe fitting and to transfer moving mechanism longitudinally.Like this, though interior pipe fitting still can be proofreaied and correct when engaging two structure members with respect to the position of outer tube member.Correcting element preferably has the laths of metal of lid shape bending, and this laths of metal also has the engagement function on the above-mentioned introducing lid meaning except calibration function.As transferring the moving mechanism suggestion to adopt two threaded shank, this bolt for example remains in the laths of metal by a kind of sliding bearing, and their screw thread is then engageable in the screwed hole of interior pipe fitting.By for example interior hexagonal part of the tool operation mechanism that is placed in the outside, bolt all can turn.By the rotation of bolt, correcting element just can move with respect to pipe fitting.

To reach the line of force of lacking as far as possible between half one in order joining, and to reach little moment effect, but a kind of preferred construction form that the present invention proposes has the force direction sensor of a plug-in mounting at coupling.This sensor is so to be installed on the outer tube member, make the interior pipe fitting that is in the force direction ranges of sensors can shift the power in following place, be the place that outer tube member can preferably bear these power, for example that is to say those power on the end of interior pipe fitting at outer tube member.The preferably simple bending of the direction sensor of power is the metal sheet of U-shape.

Three embodiment below with reference to accompanying drawings elaborate to the present invention.Accompanying drawing is represented:

The cross-sectional drawing of the connector of first embodiment of Fig. 1 is in the confined state;

The cross-sectional drawing of the pipe fitting of second embodiment of Fig. 2 connector;

The phantom drawing of Fig. 3 the 3rd embodiment of the present invention.

Connector shown in Fig. 11 is used to connect two

structure members

2 and 3, for example two walls to be connected in the prefabricated building structure.It joins half one 4 and 5 by two couplings and forms, and these two couplings join half one and utilize screw 6 to be fixed on the corresponding construction parts 2,3.Two couplings join half one 4,5 and have a pipe fitting 7,8 separately, and these two pipe fittings are being carried by the wedge shape base made from the highstrenghtpiston 9,10.The standardized quadrangle pipe that pipe fitting 7,8 is made of steel, they have different cross sections, can peg graft each other.

In order to connect two

structure members

2,3, coupling joins half one 4,5 and at first utilizes screw 6 to be fixed in the pre-assembled framework on the structure member 2,3.For this reason, screw 6 was inserted space 11, when being screwed into, finally be close on inboard 13,14 with its head of screw 12.For

structure member

2,3 really engages, will there be the coupling of the pipe fitting 8 in big cross section to join the coupling that half one 5 shifts the pipe fitting 7 in less cross section onto and join in half one 4.Wherein, introduce and to cover 15 formation that are used for engagement ramp.When

structure member

2,3 engaged, they made vertical and a kind of Union Movement level with respect to its bearing surface 16.This engagement movement obtains the support of gravity, and stops at once when bearing surface 16 contacts.Under this state, coupling join half one 4,5 since its wedge-like engagement effect and gravity so tension each other.

Fig. 2 represents the pipe fitting 7a of second embodiment, 8 cross section.Between pipe fitting 7a, 8, settled a correcting element 17.This correcting element 17 has one and is laths of metal 18 and two travel mechanisms as bolt 19 designs of covering the shape bending.Bolt 19 has screw thread 20, an interior hexagon portion 21 is respectively arranged as tool operation mechanism in both sides.Bolt is bearing in respectively in the hole 22 of laths of metal, and is meshed with the screwed hole 23 of interior pipe fitting 7a.As long as pipe fitting 7a, 8 is not among the engagement as yet, bolt 19 just can rotate abreast, thereby laths of metal 18 can be transverse to vertically being moved of this pipe fitting with respect to interior pipe fitting 7a.Because correcting element 17 joins to again in the outer tube member 8, so for example can advantageously set up the skew A of the axis shown in the figure.

Fig. 3 represents another embodiment of the connector 1b that the present invention proposes.It joins half 4b of by two couplings and 5b constitutes.Two couplings join half 4b of, 5b and have pipe fitting 7b, a 8b separately, and wherein, pipe fitting 7b designs as having the band steel of introducing inclined-plane 24.

Pipe fitting

7b, 8b are being carried by wedge shape base 9b, 10b made of plastic.Bend to the force direction sensor 26 of U-shape metal plate component form on another coupling joins the edge 25 of half 4b of, planting of outer tube member 8b.The effect of these force direction sensors is: joining the power of having an effect between half one between two couplings can directly nearby be shifted at it, thereby avoids particularly bigger leverage.
