Abstract

The utility model discloses a combination beam with high shearing resistance, and the beam comprises a prefabricated plate, a steel frame, a connecting plate, and a T-shaped connection column. The upper end of the body of the T-shaped connection column is provided with a T-shaped head. The outer peripheral surface of the body of the T-shaped connection column is provided with a thread. The steel frame is formed by the connecting of an upper wing plate, a web, and a lower wing plate from the top to the bottom. One end of the connecting plate is connected with the lower side surface of the upper wing plate, and the other end of the connecting plate is in matching connection with the prefabricated plate through a bolt and a bolt sleeve in the prefabricated plate. The prefabricated plate is connected with the steel-beam upper wing plate through the T-shaped connection column. The combination beam provided by the utility model is simple in structure. Compared with the prior art, the combination beam reduces the size of a shear-resisting connecting groove reserved in the prefabricated plate, reduces the number of connecting pieces, and reduces the usage amount of concrete, thereby reducing the cost of manufacture. The combination beam can achieve the capability of supplying double resistance to shearing, greatly improves the safety and reliability, and prolongs the service life.

Description

High shearing resistance compound beam
Technical field
The utility model relates to the steel-mixed combining structure in the fields such as a kind of civil engineering and Communication and Transportation Engineering, relates in particular to a kind of high shearing resistance compound beam.
Background technology
Steel-mixed combining structure is widely used in the field such as civil engineering and Communication and Transportation Engineering at present, in prior art, conventionally adopt plain bolt or peg to directly apply to precast assembly steel-mixed combining structure as connector, the reserved shearing resistance link slot area of precast plate is larger, when site operation, need build a large amount of concrete, if the shearing that the contact surface between shaped steel and concrete slab is subject to is excessive, mode of failure is that bolt is cut off, and now bolt generation single shear destroys.
Summary of the invention
For the defect existing in prior art, the utility model provides a kind of compound beam of high shearing resistance.
Concrete technical scheme is: a kind of high shearing resistance compound beam, comprise precast plate, steelframe, junction plate and T-shaped joint pin, the cylinder upper end of T-shaped joint pin is provided with T connector, T-shaped joint pin cylinder outer circumference surface is provided with screw thread, steelframe is formed by connecting from top to bottom by upper flange, web and lower wing plate, junction plate one end is connected with upper flange downside, and the other end and precast plate are connected by the bolt sleeve in bolt and precast plate, and precast plate is connected in girder steel upper flange by T-shaped joint pin.
Described junction plate comprises the upper plate, flap and the lower plate that connect successively, and lower plate is fixed on the lower end of steelframe upper flange by T-shaped joint pin, and upper plate is connected with precast plate lower surface.
Described junction plate comprises liner plate and horizontal connecting plate, and liner plate is embedded in precast plate in advance after being connected with bolt sleeve, and horizontal connecting plate one end upper side is connected with precast plate by liner plate, and the other end is connected with the downside of steelframe upper flange.
Be positioned on the T-shaped joint pin of steelframe upper flange upside and junction plate downside and be respectively equipped with nut.
The angle of the flap of described junction plate and upper plate and lower plate is 40 °.
The utility model is simple in structure, than prior art, reduce reserved shearing resistance Dimension of connecting channel in precast plate, reduce connector quantity, reduced concrete use amount simultaneously, thereby reduction manufacturing cost, the utility model can provide double shearing resistance ability, has greatly increased security reliability and application life.

Detailed description of the invention
Embodiment 1
As depicted in figs. 1 and 2, a kind of high shearing resistance compound beam, comprise precast plate 1, steelframe 2, junction plate 3 and T-shaped joint pin 4, the cylinder upper end of T-shaped joint pin 4 is provided with T connector, T connector is in precast plate inside, T-shaped joint pin 4 cylinder outer circumference surfaces are provided with screw thread, steelframe 2 is by upper flange 5, web 9 and lower wing plate 10 are formed by connecting from top to bottom, precast plate 1 is connected in upper flange 5 by T-shaped joint pin 4, as shown in Figure 3, junction plate 3 comprises the upper plate 6 connecting successively, flap 7 and lower plate 8, lower plate 8 is fixed on the lower end of upper flange 5 by T-shaped joint pin 4, upper plate 6 is connected by the cooperation of bolt and bolt sleeve 11 with precast plate 1.
In the time of concrete installation work, first make the precast plate 1 of corresponding size according to actual conditions, bolt sleeve is nuzzled in precast plate 1 in advance, leave shearing resistance link slot at precast plate 1 soffit for leaving T-shaped joint pin 4, the T connector of T-shaped joint pin 4 is inserted in shearing resistance link slot perpendicular to precast plate 1 soffit, shearing resistance link slot is sealed with concrete, T connector is fixed in precast plate 1, depositing the long enough time until precast plate 1 reaches after design strength, accurately measure the position of T-shaped joint pin 4 on precast plate 1, then boring on corresponding upper flange 5, by T-shaped joint pin 4 by precast plate 1, steelframe 2 is connected with junction plate 3, suffered Shear transfer is given T-shaped joint pin 4 by junction plate 3, make T-shaped joint pin 4 share shearing at two different cross sections at upper flange 5 upper side places and downside place, thereby improve shearing resistance ability of the present utility model.
Be positioned on the T-shaped joint pin of upper flange 5 upsides and junction plate downside and be respectively equipped with nut, each parts are connected more firm.The flap 7 of junction plate 4 is 40 ° with the angle of upper plate 6 and lower plate 8, makes junction plate 3 that shearing is better passed to T-shaped joint pin 4.
Embodiment 2
With reference to embodiment 1, as shown in Figure 4, liner plate 12 welds together rear nuzzling in advance in precast plate 1 with bolt sleeve 11, horizontal connecting plate 13 left part are connected with upper flange 5 by T-shaped joint pin 4, and right side part linked together horizontal connecting plate 13, liner plate 12 and precast plate 1 by bolt and coordinating of bolt sleeve 11.
