Abstract

The invention relates to a steel and concrete combined connecting piece with changeable dual column caps. The connecting piece is formed in a mounting hole of a steel mother plate in a penetrating manner and is used as a shear connecting piece of the steep mother plate and a concrete bonding surface; the connecting piece comprises a rod body and a screw cap; an end part welding stud cap is arranged at the upper end of the rod body; a middle column cap is arranged in the middle of the rod body; the rod body at the lower part of the middle column cap is arranged in the mounting hole of the steel mother plate in the penetrating manner; the nut is arranged at the lower part of the rod body and is matched with the middle column cap for clamping the rod body on the steel mother plate. Compared with the prior art, the steel and concrete combined connecting piece has the advantages of being uniform in stress distribution, convenient to use and replace, capable of reducing the influence of concrete shrinkage and creep and temperature on a combined structure and the like.

Description

A kind of double capital changeable type connector of Steel concrete combination
Technical field
The present invention relates to a kind of connector, especially relate to a kind of double capital changeable type connector of Steel concrete combination.
Background technology
The mechanical property of Steel concrete combining structure is not only subject to the impact of self material property, and has very large relation with the type of attachment of bonding surface.Type of attachment has multiple shape sample, is broadly divided into binding type, splicing type, friction-type and connector form.Conventional Steel concrete combining structure connector comprises socket cap weldering nail connector and perforated panel connector, and wherein socket cap weldering nail connector is one of the most frequently used connector, and weldering nail head can down, stand upside down upward, edge-on etc.
The endurance issues of built bridge more and more causes people's concern, and steel corrosion and concrete cracking are the subject matter that affects durability, and it not only affects the application life of structure, also can cause a large amount of potential safety hazards, even causes the accident.Connector is one of tired details of combining structure, and fatigue failure very easily occurs, and the fatigue problem of connector merits attention.In addition, because socket cap weldering nail is fixed with steel, and weldering nail integral rigidity is larger, and the effects such as concrete shrinkage and creep make the stressed totally unfavorable of weldering nail connector, and near the pressure being subject to socket cap root is larger.
Summary of the invention
Object of the present invention is exactly that the double capital changeable type connector of a kind of distribution of force Steel concrete combination even, easy to use is provided in order to overcome the defect of above-mentioned prior art existence.
Object of the present invention can be achieved through the following technical solutions:
A kind of double capital changeable type connector of Steel concrete combination, this connector is located in the installing hole of steel motherboard, shear connector as steel motherboard and concrete joint surface, described connector comprises the body of rod and nut, and the upper end of the body of rod is provided with the end weldering head of a nail, and the middle part of the body of rod is provided with middle part column cap, the body of rod of the following part of middle part column cap is arranged in the installing hole of steel motherboard, described nut is located at the bottom of the body of rod, coordinates with middle part column cap, and the body of rod is clamped on steel motherboard.
The contact position of the installing hole inwall of the surface of the body of rod and steel motherboard is provided with elastic fluid.
Described elastic fluid is rubber or the elastic resin of structure in the form of a ring.
Part on the described body of rod more than middle part column cap is smooth, and the part below the column cap of middle part is provided with screw thread.
Described nut one end opening, other end sealing.
Compared with prior art, the present invention has the following advantages:
1, meeting under the prerequisite of steel concrete bonding surface shear-carrying capacity requirement, in contact position, elastic fluid is set, suitably reduces bonding surface shear stiffness, allow it that appropriate relative slippage occurs, make the shearing of connector distribute more even.
2, at the middle part at the body of rod, increase middle column cap, effectively solved the stressed situation of root contacting with steel motherboard.
3, provide a kind of replaceable, the shear connector easily of constructing, has realized the displacement of combining structure weldering nail connector.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the present invention is arranged in Steel concrete combining structure;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the sectional view that the present invention is arranged in steel motherboard.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As depicted in figs. 1 and 2, a kind of double capital changeable type connector of Steel concrete combination, this connector 3 is located in the installing hole of steel motherboard 2, the shear connector as steel motherboard 2 with concrete 1 bonding surface.Described connector comprises the body of rod 5 and nut 7, and the upper end of the body of rod 5 is provided with the end weldering head of a nail 4, and the middle part of the body of rod 5 is provided with middle part column cap 6.The syndeton of this connector and steel plate as shown in Figure 3, on the body of rod, column cap more than 6 part in middle part is smooth, the part of middle part column cap below 6 is arranged in the installing hole of steel motherboard 2, and be provided with screw thread, on the screw thread of the body of rod bottom that nut 7 connects, coordinate up and down with middle part column cap 6, the body of rod of connector 35 is clamped on steel motherboard 2.
The invention discloses a kind of replaceable, the shear connector easily of constructing, can improve Steel concrete joint portion stress, reduces the impact of concrete shrinkage and creep on combining structure, realize the displacement of combining structure weldering nail connector, be applicable to Steel concrete combining structure engineering.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.Person skilled in the art obviously can easily make various modifications to these embodiment, and General Principle described herein is applied in other embodiment and needn't passes through performing creative labour.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and the improvement of making for the present invention and modification all should be within protection scope of the present invention.
