Beam-column connectors for building frame structures

Abstract

A beam-column connecting component comprises an integrally formed beam-column connecting component body, an upright socket which needs to be inserted and fixed to an end portion of an upright in a direction perpendicular to the horizontal plane and protrudes from the beam-column connecting component body in the vertical direction, and a horizontal supporting joint which directly supports a cross beam parallel to the horizontal plane and protrudes from the beam-column connecting component body in the horizontal direction. The upright socket comprises two symmetrical U-shaped blocks vertically protruding from the beam-column connecting component body and having openings toward two sides, round tables are formed on the bottom planes of U-shaped grooves of the two U-shaped blocks; a reinforcing rib is connected between the round tables; and a threaded through hole is formed in each round table. The beam-column connecting component has the advantages that fastening connection or welding and the like are greatly reduced, and the defects of poor stress and weak connection at the connection position due to overconcentration of stress on the connection position between the beam and the column or between the beams are greatly reduced, so that the mounting efficiency, the anti-vibration function and the use safety of the building frame structure are greatly improved, and the service lifeof the building frame structure is prolonged; and the beam-column connecting components can be produced in advance on a large scale and in a standardized manner.

Description

technical field [0001] The invention relates to a beam-column connector for building frame structures of houses, pavilions, booths, bridges, etc., in particular to a beam-column connector for building frame steel structures of house building frames. Background technique [0002] Existing cement brick mix, reinforced concrete house building and construction method thereof, owing to need to draw frame, cast concrete etc. with steel bar at the construction site, there is following shortcoming: the one is that its upright column pours and builds earlier, pours on upright column again Concrete floors are built, and the connection between the cement floor and the columns is mainly based on the steel bars on the columns and the cement floor. Since the columns and the cement floor are poured twice, the construction period is long, the labor intensity is high, the pollution is large, and the noise is large. The waste of construction raw materials is large; the second is that the rela...

[0002] Existing cement brick mix, reinforced concrete house building and construction method thereof, owing to need to draw frame, cast concrete etc. with steel bar at the construction site, there is following shortcoming: the one is that its upright column pours and builds earlier, pours on upright column again Concrete floors are built, and the connection between the cement floor and the columns is mainly based on the steel bars on the columns and the cement floor. Since the columns and the cement floor are poured twice, the construction period is long, the labor intensity is high, the pollution is large, and the noise is large. The waste of construction raw materials is large; the second is that the relationship between two cement solids is only the bearing relationship of mechanical loads, and it is impossible to establish a truly integrated internal relationship, which has poor safety, poor earthquake resistance, and short service life; third, it is necessary to use cement, Wood and other building materials destroy ecology; Fourth, when houses are demolished, building materials cannot be reused, resulting in waste of resources and a large amount of construction waste that is difficult to handle; Fourth, due to the heavy weight of the frame structure of traditional cement buildings (high-rise buildings), The mechanical load of the foundation is very large. Once an earthquake shakes, the whole building becomes very fragile and dangerous, which is not conducive to earthquake resistance.

Second, there are many bolts and other fastening connections or welding connections on site, which will increase the difficulty of installation, reduce installation efficiency, and result in high labor and time costs for on-site construction.

The third is that the traditional building steel structure frame beams and columns or beams and beams are connected by bolt fastening or welding, and the respective connection ends must be designed and processed for matching connections. When standard profiles are used for beams or columns , the connecting ends must be designed and processed separately. When beams or columns do not use standard profiles, they need to be specially manufactured. Both methods cannot achieve mass standardized production. The cost is high, and beams or columns are prone to dimensional processing errors. The connection error makes it difficult for the already fragile connection position to bear the weight load of the building and the transmission of load force

Although in this technical scheme, the column member supports the lower column joint, the lower column joint supports the beam bucket, the beam bucket supports the upper column joint, the upper column joint supports the column member, and the beam bucket supports the beam bucket. It has a supporting function, and the gravity load of beams, columns, floors, etc. will not be transmitted to the welds and fasteners of the connecting nodes to bear; but the connection between the column members and the beams in this technical scheme needs to be connected through the upper column Joints, lower column joints, and beam buckets can only be realized. The disadvantages are: first, the combination of multiple parts can realize the connection between the column member and the beam, poor rigidity, and large assembly errors; Between the beam bucket and the beam bucket, the joint between the beam bucket and the upper column, and the joint between the upper column and the column member need to be fixed by self-pressing bolts or welding. There are many procedures and time-consuming installation. Many installation links will cause the verticality of the column member and its installation position It is difficult to adjust; in this technical scheme, the rigidity of multiple parts connecting column members and beams is poor, and the rigidity of the combination is even worse, which is not conducive to the bearing and transmission of heavy loads; the third is that the gravity of beams, columns, floors, etc. are transmitted in the end The connecting node is borne by the horizontal part of the beam bucket supported on the joint of the lower column, which will cause excessive stress concentration on the connecting node between the beam and the column or between the beam and the beam, so that the connecting node is poorly stressed and the connection is fragile, which will greatly Reduce the safety of the building frame structure and shorten the service life
