Description

Connection node between frame column and composite grid floor

1. Technical field:

The utility model relates to a connection node between a house frame column and a floor slab in the field of civil building structures, in particular to a connection node between a frame column and a composite grid floor.

2. Background technology:

The houses built with reinforced concrete frames or prestressed concrete frames now mostly use reinforced concrete structures for their floor slabs. In the process of adding floors to existing houses, it is difficult to guarantee the safety of the original houses during the process of building and adding floors. and normal use; the high-rise or super high-rise building of the concrete mega-frame structure has not yet been realized to build the mega-structure first, and then use each mega-structure layer as the construction site to build the sub-structure. A house built with a combined grid structure as a floor frame uses a reinforced concrete slab to replace the upper chord of a general steel grid, thereby forming a combined structure in which the steel structure and the reinforced concrete structure work together, which is a system of slabs and beams. The combined structure and the bar system are jointly stressed. Since the upper part of the combined grid structure is under compression and the lower part is under tension, the strength advantages of the two different materials, concrete under compression and steel under tension, can be fully utilized to realize self-supporting during the construction stage. The connection between the column and the floor slab of a house built with a reinforced concrete frame cannot be adapted to a house built with a combined grid floor slab.

3. Contents of the invention:

The purpose of this utility model is to provide a connection node between the frame column and the combined grid floor, which is used to solve the problem that the connection between the column and the floor of the existing house built with a reinforced concrete frame cannot be adapted to the house built with the combined grid floor The problem.

The technical scheme adopted by the utility model to solve its technical problems is: the connection node between the frame column and the combined grid floor is formed by inserting and welding the upper and lower split groove-shaped connectors outside the frame column, and the upper connection There is an arc-shaped groove on the lower edge of the two faces corresponding to the split body, and there is a horizontal connecting plate on the lower edge of the other face of the upper part connecting the split body; the upper part of the two faces corresponding to the lower connecting split body Each edge has an arc-shaped groove, and the upper edge of the other side of the lower connecting split body has a horizontal connecting plate, and a stiffener is installed between the connecting plate and the frame column.

In the above scheme, the horizontal connecting plates connecting the upper and lower split bodies are fixed by bolts.

Beneficial effect:

1. The utility model bears reasonable force, organically combines the force-bearing rod and the support, and realizes stronger joints.

2. The groove-shaped connectors in the utility model are prefabricated in the factory, and the installation is simple and convenient for construction.

5. Specific implementation methods:

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 5, the frame of the floor slab with a composite grid structure is composed of frame columns 1, frame side beams 2, and composite grid floor 3. It uses a reinforced concrete slab to replace the upper chord of a general steel grid, thus forming a A composite structure in which steel structures and reinforced concrete structures work together is a composite structure in which slab systems, beam systems, and rod systems are jointly stressed; composite grid floor slabs 3 are installed on frame columns 1 and frame side beams layer by layer In the space enclosed by 2, the combined grid floor 3 is formed by installing the reinforced concrete slab 4, the web 5 and the lower chord 6 of the grid, and the web 5 is located between the reinforced concrete slab 4 and the lower chord 6; the frame column 1 is connected to the composite grid floor 3 through nodes, and the frame side beam 2 is connected to the composite grid floor 3 through nodes. The frame column 1 adopts square steel pipe concrete columns, and the frame side beam 2 adopts round steel pipe concrete beams. The combined grid frame has high rigidity and light weight, and is suitable for building large-span floor structures with large loads, such as warehouses, factories, department stores, exhibition halls, etc. In addition, the self-supporting structure of the construction stage can be realized in the building and adding layers, and the construction load can be avoided to be transmitted to the original building.

What the utility model provides is a connection node between the frame column and the combined grid floor, combined with Fig. 1 and Fig. 4, the connection node between the frame column and the combined grid floor is composed of upper and lower split grooves The shape connector 7 is inserted and welded outside the frame column 1 to form, the lower edges of the two corresponding surfaces of the upper connecting split body each have an arc-shaped groove, and the lower edge of the other side of the upper connecting split body has a convex platform, the boss has a horizontal connecting plate 8; the upper edge of the corresponding two faces of the lower connecting split body has an arc-shaped groove, and the upper edge of the other face of the lower connecting split body has a groove, There is a horizontal connecting plate 8 on the edge of the bottom surface of the groove, and a stiffener 10 is installed between the connecting plate 8 and the frame column 1; the upper and lower connecting parts are installed at the intersection of the frame column 1 and the frame side beam 2 At the same time, the frame side beam 2 is buckled in the upper and lower arc-shaped grooves, and at the same time, the boss of the upper connecting split extends into the groove of the lower connecting split, and the two horizontal connecting plates 8 are fixed together by bolts 9 That is, the reinforced concrete slab 4 is fixedly connected to the connecting plate 8 below it, and the web bar 5 is welded to the connecting plate 8 .

Groove connectors are shown in Figure 2 and Figure 3. This connector can be manufactured in the factory first and installed on site. When installing, first install the upper connector, then install the lower connector, and then connect the two with bolts. Fixed, because the upper connecting piece can be buckled on the frame side beam 2, so it does not need to be supported, the installation of the lower connecting piece can be directly carried out, which is more convenient.
