Beam hanger, building framework structure and installation method

Abstract

The invention discloses a beam hanger, a building framework structure and an installation method. The beam hanger comprises a beam inserting joint or a beam supporting joint, a hanging part and a connecting part formed integrally; the beam inserting joint comprises a square tube shaped convex part extended from the end face of the vertical connecting part; elastic convex tongues are arranged on the lateral surfaces of the square tube shaped convex part; one end, far from the connecting part, of the elastic convex tongue is connected to the square tube shaped convex part; and the other end, facing the connecting part, of the elastic convex tongue is a free end. The building framework structure comprises more than two beam hangers, a beam, two ends of which are fixed with the beam insertingjoints or the beam supporting joints of the beam hangers, and a beam which is directly supported by the hanging parts of the beam hangers and hung thereon. The installation method comprises the following steps of: inserting the two ends of the beam into the beam hangers, movably connecting the beam and the beam hangers, hanging the beam hangers on the corresponding beam, adjusting the relative positions of the beams and the beam hangers, and fixing the beam hangers and the beams. The invention has the advantage that: connection of the beams can be finished conveniently and quickly.

[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

[0011] In the frame structure of the existing steel structure of the house, the connection between the beams can only be realized through the support of the columns. The technical solutions disclosed in the above-mentioned patents are all like this. This frame structure is suitable for large spaces or Buildings that require dense beams to support either need a lot of columns to support, which affects the usable space and aesthetics of the room, or the beams do not support the board installed on them well, affecting the service life and safety of use ; One is to weld the end face of one beam to the side of another beam, or to weld the end faces of two beams together. Or welding and other methods to fix the ends of the two beams together with non-plug connectors. In this connection method, the gravity of the beam and the gravity of the plate supported on the beam are finally concentrated on the fastener or welded The position of the node, the stress is excessively concentrated on the connection position between the beam and the beam, so that the connection position is poorly stressed and the connection is fragile

Fasteners are not possible without the use of additional connectors because of the need to fasten the end face of one beam to the side of the other beam
