Description
Technical Field
[0001] The utility model belongs to the technical field of steel structure installation, and in particular relates to an assembled steel structure connection device. Background Art
[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields.
[0003] In existing steel structure buildings, the connection between cement columns and steel structure beams is a relatively common combination method. The existing technology generally involves driving chemical bolts or expansion bolts into the cement columns, then fitting the T-plate onto the bolts, and then tightening the T-plate onto the cement columns with nuts, and finally connecting the T-plate to the steel beams with bolts to complete the connection. However, the above structure does not have a buffering effect; when the beam is subjected to a large impact, such as when a heavy object falls from the steel platform on the beam, the beam will deform, and the end of the beam will apply a force to the cement column. Due to the high brittleness of the cement column, cracks often occur after being subjected to force, and even breakage occurs, which poses a great safety hazard. Utility Model Content
[0004] In view of the above problems, the purpose of the utility model is to provide an assembled steel structure connection device to solve the problem that the existing rigid connection method between cement columns and steel beams will cause damage to the cement columns when the beams are subjected to a large impact.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is: an assembled steel structure connection device, including a cement column, a fixing bolt is installed on the cement column, a buffer T-plate is connected and fixed by the fixing bolt, and the buffer T-plate includes a connecting steel plate, a double-sided support plate and a buffer pad are arranged on one side of the connecting steel plate, the double-sided support plate is inserted with connecting bolts, a buffer steel frame is mounted on the outer side of the connecting bolt, the buffer steel frame consists of an inner bracket and an outer bracket, the buffer steel frame is installed on the inner side of a buffer slot hole, the buffer slot hole is opened on a steel beam, the web of the steel beam is inserted on the inner side of the double-sided support plate and the end of the steel beam is abutted against the buffer pad.
[0006] The beneficial effect of the utility model is that when the steel beam is subjected to a large impact force causing displacement at both ends, the buffer pad plays the role of buffering and supporting the end of the steel beam, while the buffer steel frame produces elastic deformation, thereby achieving the effect of energy absorption and buffering and supporting the steel beam, thereby preventing the concrete column from being damaged by the steel beam.
[0007] In order to effectively ensure the installation stability of the buffer steel frame;
[0008] As a further improvement of the above technical solution: the double-sided support plate is composed of two plate bodies welded parallel to each other on a connecting steel plate.
[0009] The beneficial effect of this improvement is that the double-sided support plates arranged on both sides of the web of the steel beam can limit the buffer steel frame and prevent the buffer steel frame from falling out of the buffer slot hole.
[0010] In order to avoid collision between the double-side support plates and the flange of the steel beam when the buffer steel frame undergoes elastic deformation;
[0011] As a further improvement of the above technical solution: the minimum distance between the upper and lower end surfaces of the double-sided support plates and the upper and lower flanges of the steel beam is not less than the radius difference between the connecting bolts and the buffer slot holes.
[0012] The beneficial effect of this improvement is that the maximum up and down distance that the steel beam moves on the connecting bolt is not greater than the radius difference between the connecting bolt and the buffer slot hole, thereby avoiding collision between the double-sided support plates and the flange of the steel beam, which in turn leads to the failure of the buffering effect of the buffer steel frame.
[0013] In order to make the buffer steel frame play an effective buffering role;
[0014] As a further improvement of the above technical solution: the inner bracket is composed of a plurality of arc-shaped plate structures with colinear axes, the outer bracket is arranged between adjacent inner brackets, the outer bracket is an arc-shaped plate structure, the outer side surface of the outer bracket is connected to the inner wall of the buffer slot hole, and the inner wall of the inner bracket is connected to the surface of the screw of the connecting bolt.
[0015] The beneficial effect of this improvement is that the connecting bolts produce relative displacement with the steel beam under the limitation of the double-sided support plates. At this time, the outer bracket plays a supporting role, and the inner bracket produces elastic deformation to achieve the effect of energy absorption and buffering the support of the steel beam, thereby preventing the concrete column from being damaged by the steel beam.
[0016] In order to effectively prevent the end of the steel beam from squeezing and damaging the surface of the cement column when it moves through the use of a buffer pad;
[0017] As a further improvement of the above technical solution: the buffer pad is a strip rubber plate structure, and the buffer pad is fitted to one end of the upper and lower flanges of the steel beam.
[0018] The beneficial effect of this improvement is that the buffer pad plays the role of buffering and supporting the end of the steel beam, thereby preventing the end of the steel beam from squeezing and damaging the surface of the cement column when moving.
[0019] In order to effectively ensure the connection strength between the buffer T-plate and the steel beam;
[0020] As a further improvement of the above technical solution: the number of the buffer slot holes is multiple.
[0021] The beneficial effect of this improvement is that the buffer steel frames installed in the multiple buffer slot holes can stably support the connecting bolts, so that a stable connection is maintained between the steel beam and the buffer T-plate.
[0022] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.
[0030] Embodiment 1:
[0031] like Figure 1—5 shows: an assembled steel structure connection device, including a cement column 1, on which a fixing bolt 2 is installed, and a buffer T-type plate 3 is connected and fixed by the fixing bolt 2, and the buffer T-type plate 3 includes a connecting steel plate 31, and a double-sided support plate 32 and a buffer pad 33 are arranged on one side of the connecting steel plate 31, and a connecting bolt 4 is inserted on the double-sided support plate 32, and a buffer steel frame 6 is sleeved on the outer side of the connecting bolt 4, and the buffer steel frame 6 is composed of an inner bracket 61 and an outer bracket 62. The buffer steel frame 6 is installed on the inner side of a buffer slot hole 7, and the buffer slot hole 7 is opened on a steel beam 5, and the web of the steel beam 5 is inserted in the double-sided support plate 32. The inner side and the end of the steel beam 5 are against the buffer pad 33. When the steel beam 5 is subjected to a large impact force and causes displacement at both ends, the buffer pad 33 plays the role of buffering and supporting the end of the steel beam 5. At the same time, the buffer steel frame 6 produces elastic deformation to achieve the role of energy absorption and buffering and supporting the steel beam 5, thereby preventing the concrete column 1 from being damaged by the steel beam 5. The double-sided support plate 32 is composed of two plates welded to the connecting steel plate 31 in parallel with each other. The double-sided support plates 32 arranged on both sides of the web of the steel beam 5 can limit the buffer steel frame 6 and prevent the buffer steel frame 6 from escaping from the buffer slot 7. The upper and lower end surfaces of the double-sided support plates 32 are aligned with the upper and lower flanges of the steel beam 5. The minimum distance is not less than the radius difference between the connecting bolt 4 and the buffer slot hole 7, and the maximum upper and lower distance that the steel beam 5 moves on the connecting bolt 4 is not greater than the radius difference between the connecting bolt 4 and the buffer slot hole 7, thereby avoiding collision between the double-sided support plate 32 and the flange of the steel beam 5, which in turn leads to the failure of the buffering effect of the buffer steel frame 6. The inner bracket 61 is composed of a plurality of colinear arc plate structures, and the outer bracket 62 is arranged between adjacent inner brackets 61. The outer bracket 62 is an arc plate structure, and the outer side surface of the outer bracket 62 is connected to the inner wall of the buffer slot hole 7, and the inner wall of the inner bracket 61 is connected to the surface of the screw of the connecting bolt 4. The connecting bolt 4 is limited in the double-sided support plate 32 The outer bracket 62 plays a supporting role, and the inner bracket 61 produces elastic deformation to achieve the effect of energy absorption and buffering support of the steel beam 5, so as to prevent the concrete column 1 from being damaged by the steel beam 5. The buffer pad 33 is a strip rubber plate structure, and the buffer pad 33 fits one end of the upper and lower flanges of the steel beam 5. The buffer pad 33 plays the role of buffering and supporting the end of the steel beam 5, so as to prevent the end of the steel beam 5 from squeezing and damaging the surface of the concrete column 1 when moving. There are multiple buffer slots 7, and the buffer steel frames 6 installed in the multiple buffer slots 7 can stably support the connecting bolts 4, so as to maintain a stable connection between the steel beam 5 and the buffer T-plate 3.
[0032] The working principle of this technical solution is as follows: first, pre-install the fixing bolt 2 in the cement column 1, and the position of the fixing bolt 2 is opposite to the position of the mounting hole opened on the connecting steel plate 31, and then the connecting steel plate 31 is mounted on the fixing bolt 2, and then tightened with a nut, and then the buffer steel frame 6 is placed on the inner side of the buffer slot 7, and then the web of the steel beam 5 is inserted into the inner side of the double-sided support plate 32, and the connecting bolt 4 is inserted into the inner side of the buffer steel frame 6, and the steel beam 5 and the buffer T-shaped plate 3 are stably connected after tightening with nuts. At this time, the end of the steel beam 5 is tightly attached to the buffer T-shaped plate 3; when the steel beam 5 is subjected to a large impact force and displacement occurs at both ends, the buffer pad 33 plays the role of buffering and supporting the end of the steel beam 5, and at the same time, the connecting bolt 4 is relatively displaced with the steel beam 5 under the limitation of the double-sided support plate 32, and at this time, the inner bracket 61 produces elastic deformation, so as to achieve the effect of energy absorption and buffering and supporting the steel beam 5, thereby preventing the cement column 1 from being damaged by the steel beam 5.
