Abstract
The utility model relates to a T-shaped profile steel connecting part, which comprises a web plate and a flange plate. Holes are arranged on the web plate and the flange plate which are perpendicular to each other. Compared with other traditional connecting parts in the prior art, under the premise of ensuring effective connection of steel with concrete in a combined structure, the T-shaped profile steel connecting part is capable of decreasing the use number of connecting parts, reducing manufacture and installation costs, accelerating construction speed of projects, and reducing the overall construction cost of the projects.
Description
Technical field
The utility model relates to a kind of connection steel and concrete device, especially relates to a kind of tee bar connector.
Background technology
At present, the connector that in steel and concrete combined structure steel and concrete is coupled together mainly contains forms such as curved muscle connector, weldering nail connector and perforated panel connector.Wherein curved muscle connector seldom uses in engineering owing to joint efficiency is low, weldering nail connector is one of the maximum connector form of using in the engineering at present, this connector needs special welding apparatus, operation is inconvenience comparatively, the joint efficiency of single weldering nail connector is lower, in structure, need intensive layout, consider the supporting capacity reduction greatly again of welding the nail connector after the fatigue resistance.
The perforated panel connector is at present a kind of newer connector relatively, and the joint efficiency of this connector is bigger than the weldering nail, does not need special welding apparatus, and anti-fatigue performance is progressively adopted by engineering circle than the height of weldering nail connector simultaneously.The concrete in the hole connects in the plate but the perforated panel connector only relies on, its joint efficiency and ductility are still lower, therefore if can be in conjunction with the perforated panel connector with respect to the high characteristics of other form connector joint efficiencies, further the connector of development of new will improve steel and concrete joint efficiency greatly.
Summary of the invention
The purpose of this utility model is exactly that a kind of simple for production, tee bar connector that joint efficiency is higher is provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of tee bar connector comprises web and frange plate, it is characterized in that, offers perforate on described web and the frange plate.
Described web is vertical mutually with frange plate.
Described perforate is circular hole, elliptical aperture or slot.
On the described web on perforate and the frange plate perforate for being crisscross arranged.
Perforate is for being arranged in parallel on perforate on the described web and the frange plate.
Perforate on the described web is equidistantly to arrange.
Perforate on the described web is that non-equidistance is arranged.
In addition, can there be reinforcing bar to pass in the perforate of offering on the web, also can not have reinforcing bar to pass.
Perforate on web and the frange plate can be a kind of specification.
Compared with prior art, employed utensil was followed the identical of perforated panel connector when the utility model was made, making than weldering nail connector is more easy, the joint efficiency of this utility model connector of while is higher than perforated panel, the tee bar connector is used in steel and concrete combined structure, because its joint efficiency is all higher than traditional weldering nail connector and perforated panel connector, and the factory process workload is little, welding job amount in building site is also few.Behind steel and concrete combined structure employing tee bar connector, make its usage quantity follow closely lacking of connector and perforated panel connector like this, shorten the construction period of engineering, save project total cost than traditional weldering.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the mode of occupation schematic diagram.
1 is that connector, 11 is that web, 12 is that frange plate, 13 is that perforate, 2 is that girder steel, 3 is that reinforcing bar, 4 is a concrete among the figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of tee bar connector, its structure as shown in Figure 1, this connector 1 is made of web 11 and frange plate 12, web 11 and frange plate 12 mutual vertical T-shaped structures offer perforate 13 on web 11 and the frange plate 12.The shape of perforate 13 can be circular hole, elliptical aperture or slot, and the perforate on perforate on the web 11 and the frange plate 12 can be for being crisscross arranged or being arranged in parallel, and the perforate 13 on the web 11 can be for equidistantly arranging or the non-equidistance arrangement.In addition, can have reinforcing bar to pass in the perforate of offering on the web 11, also can not have reinforcing bar to pass, perforate 13 can be a kind of specification.
The tee bar connector can adopt H shaped steel or i shaped steel to make, and is cut to two T shape parts in the centre.Mode of occupation of the present utility model as shown in Figure 2.The web 11 of tee bar connector 1 and girder steel 3 link to each other by twin fillet wolt, make tee bar connector 1 be wrapped in fully in the concrete 4 by fluid concrete 4 then, wait concrete 4 sclerosis back tee bar connectors 1 to be combined as a whole fully with concrete 4.In addition, before concreting, place the joint efficiency that reinforcing bar 3 strengthens concrete and tee bar connector 1 in the perforate 13 on the web of connector 2, the method of placing reinforcing bar in the laying method of reinforcing bar 2 and the engineering in the perforated panel connector is identical, the proportionate relationship of hole diameter should be carried out particular study in the diameter of reinforcing bar and the steel plate, this reinforcing bar muscle of being advocated in the reinforced concrete structure, distributing bar etc. often in addition, therefore not needing to dispose special reinforcing bar at the tee bar connector passes hole, and reinforcing bar and hole do not need special measure to fix.
The utility model tee bar connector is applied in steel and the concrete combined structure, can couple together steel work and concrete effectively, its catenation principle is as follows: at first, tee bar connector 1 and girder steel 2 are connected by twin fillet wolt, this weld seam not only can transmit along the girder steel length direction shearing of (being parallel to bead direction), can also bear power, guarantee that by weld seam girder steel 2 is connected with the effective of tee bar connector 1 perpendicular to bead direction.Secondly, tee bar connector 1 mainly contains the following aspects with being connected of concrete 4: 1. the perforate on the web 13 has concrete about 4 to connect, and forms to connect falcon, and this falcon can be born bigger shearing force; 2. the perforate on the frange plate 13 makes concrete 4 at edge of a wing up/down perforation, forms to connect falcon, and this falcon can be born bigger shearing force; 3. the side of tee bar connector 1 and top closely contact with concrete 4, and along under girder steel 2 portraitlandscapes and the vertical effect, concrete has also increased connector greatly with the partial pressing of tee bar contact surface and has been connected with concrete; 4. in the perforate 13 of tee bar connector the reinforcing bar of running through 3 is arranged, the powerful horizontal shear resistance of this reinforcing bar has also increased connector and has been connected with concrete.
Therefore, the tee bar connector is used in steel and concrete combined structure, its joint efficiency is all higher than traditional weldering nail connector and perforated panel connector, behind steel and concrete combined structure employing tee bar connector, make its usage quantity follow closely lacking of connector and perforated panel connector like this than traditional weldering, can accelerate speed of application, save cost, when adopt with tee bar connector that perforated panel connector quantity equates after, structure has bigger safety stock.
