Description

Preformed frame component of hollow ferro-concrete

The utility model relates to the concrete prefabricated framing component of building precast framing component, particularly hollow steel bar.

Existing precast frame member all is a solid, and it can be divided into small members and large-scale component, and the small members formwork has subsides, benefit, cuts a hole, picks problem, or cause distortion after pouring is subjected to displacement phenomenon easily, and manufacturing process is long; Large-scale component adopts the convex-concave member to combine at node, because node is subjected to moment bigger, adopts again and fills out concrete placing the convex-concave position is combined, and construction is inconvenient, be difficult to guarantee physical dimension, and shockproof properties is poor simultaneously.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art with not enough, and designs the concrete prefabricated framing component of a kind of hollow steel bar, and it can avoid the deformation of member and offset phenomena to take place, and is accurate by dress job specfication, physical dimension, and can be shockproof.

The purpose of this utility model realizes by following technical proposal:

The concrete prefabricated framing component of hollow steel bar comprises column and crossbeam, it is characterized in that:

A) column is an open squares cross section body, and two ends are reserved prestressed reinforcement and passed the end steel plate and be welded into one;

B) crossbeam is a hollow rectangle cross section body, and two ends are reserved prestressed reinforcement and passed the end steel plate and be welded into one;

C) column node place installs stirrup additional.

Framing component of the present utility model also can make shockproof, and the concrete prefabricated framing component of hollow steel bar is made up of column and crossbeam, it is characterized in that:

A) column is an open squares cross section body, and two ends are reserved prestressed reinforcement and passed the end steel plate and be welded into one;

B) crossbeam is a hollow rectangle cross section body, and two ends are reserved prestressed reinforcement and passed the end steel plate and be welded into one;

C) column node place installs the two sections stirrup additional, is welded with the angle bar of band circular hole on the stirrup;

D) in crossbeam one end that is connected with column threaded embedded bar is housed.

Owing to take technique scheme, make to the utlity model has in light weightly, save raw material, easy construction, the quality height, size is accurate, intensity height, the advantage of short construction period and effect.

Description of drawings:

Fig. 1 is the pillar construction schematic diagram;

Fig. 2 is the beam structure schematic diagram;

Fig. 3 installs two sections stirrup structural representation additional for the column node;

Fig. 4 is the crossbeam one end structure schematic diagram that is connected with the column node.

Below in conjunction with accompanying drawing embodiment the utility model technology is further specified:

It is hollow (1) square sectional body for Fig. 1 column (5), two ends are reserved prestressed reinforcement (2) and are passed end steel plate (3) and be welded into one, install stirrup (4) additional at the node place that column is connected with crossbeam, steel plate and stirrup adopt the 2mm steel plate to get final product.

It is hollow (6) rectangle cross section body for Fig. 2 crossbeam (9), and two ends are reserved prestressed reinforcement (7) and passed end steel plate (8) and be welded into one.

When column and column connect into framework, the reserved steel bar butt joint of earlier column of butt joint being reserved welds, and then butt welding steel plate, so promptly fastening, its frame size is also accurate, the very Fang Quan that constructs, when column and crossbeam are linked to be framework, stirrup and beam-end reinforcing bar and the steel plate butt welding installed additional by column node place.

Fig. 3 installs two sections stirrup situations additional for the column node, and this is to be used for the shockproof structure framework, is welded with the angle bar (10) of band circular hole (11) on two sections stirrups of column (12), is used to connect crossbeam beam face.

Fig. 4 is the crossbeam one end structure schematic diagram that above-mentioned column node connects, in end, install threaded prestressed reinforcement (16) additional, when being connected with the column node, weld the angle bar on the stirrup of column node bottom earlier, the prestressed reinforcement of crossbeam end is stretched in the circular hole of angle bar, bar diameter is less than Circularhole diameter, there is activity entirely during with the assurance earthquake, again top angle bar being aimed at the top prestressed reinforcement is welded on the stirrup of epimere again, use nut (13) packing ring (14) again, breach retainer (15) is fastening, the framework of this structure can prevent to shake the damage of generation to building, as earthquake generation severe vibration or other to round displacement, welding node is torn the steel plate phenomenon, but the building that can not collapse, personnel can make good one's retreat after shake.
