Description

Beam hook, building frame structure and installation method

technical field

The invention relates to a beam hooking piece for building, a frame structure and an installation method for the frame structure, in particular to a beam hooking piece, a beam frame structure and a method for installing the beam frame structure of a building frame steel structure.

Background technique

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 the earthquake shakes, the whole building becomes very fragile and dangerous, which is very unfavorable for earthquake resistance. For the above-mentioned deficiencies of existing cement-brick-mixed, reinforced-concrete house constructions, existing steel structure buildings exist.

Existing steel structure buildings and construction methods thereof, although relative to cement-brick-concrete, reinforced concrete building constructions and construction methods thereof, have many advantages, there are still deficiencies, mainly as follows:

One is that the beams and columns of the existing building steel structure frame or the beams and beams are directly connected by fasteners such as bolts or through welding, etc., the force is poor, the connection is weak, and the gravity of the beams, columns, floors, etc. is finally uniform. It is transmitted to the connection node and is borne by the connection fastener or welding part, which will cause excessive stress concentration on the connection node between the beam and the column or between the beam and the beam, making the connection node less stressed and the connection more fragile, which will greatly reduce The safety of the existing building frame structure shortens the service life. This is the biggest technical problem existing in the existing traditional building steel structure frame. The second is that there are many bolts and other fastening connections or welding connections on site, which will increase the difficulty of installation, reduce installation efficiency, and cause 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.

In view of the deficiencies of the existing steel structure building frame, the existing technology mainly has the following improvements:

In the invention patent with the application number 03134271.X, a design method of an environment-friendly detachable beam-column load-bearing structure is disclosed. The invention relates to a housing support, especially a detachable housing support. It is characterized in that: the housing support is composed of a load-bearing column of the house, a load-bearing beam, a connector, and a column cap; the load-bearing beam is plugged into the load-bearing column; the load-bearing column is plugged into the column cap; The tenon of the column cap, the upper and lower column connecting bolts in the center of the top, the screw hole in the bottom center of the load-bearing column, the connection between the columns and the columns, the dovetail tenon of the load-bearing beam is inserted into the dovetail groove on the column cap, and the clamp at the bottom of the column cap The groove is connected with the dovetail tenon of the column top cap, and the upper part of the column cap is connected with the dovetail groove and the load-bearing beam dovetail tenon. Different from traditional on-site pouring, factory-made accessories and on-site assembly, components of various sizes can be arbitrarily assembled into various styles of houses on site, and can be reused after disassembly to reduce construction waste. Realize the standardization of the main structural parts, and add rubber pads between the parts of the general building components to buffer the seismic waves and enhance the seismic performance. The building components are detachable and reusable after installation, reducing a large amount of construction waste, and the construction is simple, reducing the labor intensity of construction personnel, and solving the problem of existing engineering construction that has large environmental pollution, high noise, long cycle, and excellent project quality. low problem. However, the load-bearing column of this technical solution does not use the existing standard building profiles such as I-shaped steel, H-shaped steel, square steel pipe, round steel pipe, etc., but uses non-standard parts with more complicated column feet and column heads. The column needs to be specially manufactured at one time. On the one hand, because the load-bearing column is several meters long, the mold cost and production cost are quite high. The height of the building requires different molds to form load-bearing columns of different lengths. For different buildings, load-bearing columns of different sizes need to be formed, which further increases the cost of the mold. In addition, the load-bearing columns are so large that it is very difficult to form them at one time. unrealistic. The cantilever beam and the column head are matched with dovetail groove and dovetail tenon. If the cantilever beam adopts standard I-shaped steel, H-shaped steel, square steel pipe, round steel pipe, channel steel, etc., because its cross section is not solid, it is processed into dovetail tenon. Its strength is poor.

In the invention patent with the application number of 99109701.7, a steel structure house construction component is disclosed, including a concrete steel pipe column, a steel beam support and a U-shaped steel beam. The steel beam support is composed of at least one support welded around the steel pipe column. Each bracket is composed of upper and lower column-holding plates arranged in parallel, and at least a pair of connecting plates vertically arranged between the upper and lower column-holding plates in the radial direction. The upper and lower column-holding plates have an arc surface, a body part and a connecting At least two pairs of connecting plates are formed on the steel beam bracket, and the corresponding extending parts of each pair of connecting plates and the upper column-holding plate and the lower column-holding plate are fixed to one end of the U-shaped steel beam. Together. Since the steel beam support of this technical solution is composed of at least one support welded around the steel pipe column, the gravity of the beam, column, floor, etc. is finally transmitted to the connecting node and is borne by the weld between the steel pipe and the support, which will cause excessive stress concentration The connection nodes between beams and columns or between beams and beams make the connection nodes poorly stressed and the connections are fragile, which will greatly reduce the safety of the building frame structure and shorten the service life.

In the invention patent with the application number of 200810229754.9, a light-weight steel structure building connection butt joint is disclosed, including a convex end combination, a concave end combination, an upper pipe, a lower pipe, a beam, and a wedge plate; The upper end of the end combination is outside; the middle part of the convex end combination has a step, and the lower end is inserted into the upper end of the concave end combination; the lower tube is set outside the lower end of the concave end combination; The wedge plate is connected by bolts, nuts and washers, and the wedge end of the wedge body combined with the wedge plate and the beam is correspondingly inserted into the chute on the lug plate of the concave end combination and locked by the cross pin locking piece tight. Since the connection between the square pipe and the beam in this technology needs to be completed through the joint action of the convex end combination, the concave end combination, the wedge plate, the cross pin, the bolt, and the nut, there are many installation links, especially the gravity of the beam, column, floor, etc. Finally, it is transmitted to the cross pins and bolts on the connecting nodes to bear, which will cause excessive stress concentration on the connecting nodes between beams and columns or between beams and beams, resulting in poor stress on the connecting nodes and weak connections, which will greatly reduce the frame structure of the building. The safety, shorten the service life, installation is also inconvenient.

In the utility model patent with the application number 00218061.8, a general node device for steel structure buildings is disclosed, which is composed of steel corbels, steel columns, and steel beams. The steel corbels include node connecting plates, webs, reinforcement plates, and steel corbels. The joint plate of the joint adopts channel-shaped steel, which is integrated with the web plate and the reinforcement plate, and the structure of the joint device is consistent. On the one hand, this structure needs to match the reinforcement plate with the shape of the steel column. Due to the poor manufacturing precision of the steel column, the poor fit will affect the force. When the steel column is a cylindrical tube, the matching effect is even less ideal; on the other hand The joint connecting plate, web plate, and reinforcing plate are fixed together as independent parts, not integrally formed, and their stress is poor, especially the gravity load of beams, columns, floors, etc., is finally transmitted to the welding joints and fasteners of the joint joints. Bearing, this will cause excessive stress concentration on the connection nodes between beams and columns or between beams and beams, resulting in poor stress on the connection nodes and fragile connections, which will greatly reduce the safety of the building frame structure, poor earthquake resistance, and shorten the service life.

The closest existing technology is the invention patent of 97101724.7, which discloses a steel-plastic light building and its construction method. It is a thin-walled light steel injection-molded building. It is formed by the combination of foamed plastic molding, which is mainly composed of column components, upper and lower column joints, double single beam buckets, column bases, floor beam components, window roof (platform) beams, plastic panels, floor pavilion grids, tension rods, Injection-molded floor slabs, beam-column clips, vertical bar components, column-beam clips, ground frame braces, base plates, elastic cushions, foundations, array lime piles, ground anchors, etc. are connected to each other. 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 lower column joint, 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.

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 At the node position, 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 cannot be achieved without the use of additional connectors, since the end face of one beam needs to be secured to the side of the other beam.
