Abstract

A reinforced concrete door/window frame comprises a sealed frame, and is characterized in that an L-shaped reinforced concrete precast member is arranged at each of four corners of the sealed frame, reinforced concrete cast-in-situ members are arranged between the L-shaped reinforced concrete precast members at the four corners. The L-shaped reinforced concrete precast members are provided with a plurality of through holes. Connectors fixed with the surrounding walls are fitted to the through holes, and protruding bars are arranged at two ends of the L-shaped reinforced concrete precast members. Each reinforced concrete cast-in-situ member comprises a reinforcing cage, the reinforcing cages are in lap joint with the protruding bars of the L-shaped reinforced concrete precast members, and drawing ribs connected with the wall are arranged on the reinforcing cages. The reinforced concrete door/window frame is high in rigidity, so for brickwork houses with large door/window holes on the wall, rigidity and shear resistance of the wall with holes can be greatly improved, adverse effect of torsional effect under the action of earthquake is reduced, and integral anti-seismic property of the houses is improved. Besides, the reinforced concrete door/window frame is simple in structure, convenient to construct, short in construction period and applicable to industrialized implementing and has practicality.

Description

A kind of steel concrete doorframe and window frame

Technical field

The utility model relates to a kind of steel concrete fabricated structure doorframe and window frame, be particularly related to and a kind ofly be applicable to that the wall body door or window hole area is excessive, the door and window size is various, interfenestration is less, in order to improve the masonry house anti-seismic steel bar concrete door window frame of masonry house anti-seismic performance.

Background technology

At present, northern country generally adopts masonry house.Need for daylighting, preceding vertical wall door and window hole area is bigger, and the width of wall between windows is too small, the door and window size is various, thereby causes preceding vertical wall rigidity and shear-carrying capacity to seriously undermine, the problem that the vertical wall rigidity in front and back and bearing capacity difference are excessive.In recent years repeatedly earthquake and shaketalle test show that all the anti-seismic performance of this structure is very poor.

According to the requirement of earthquake resistant design code, wall between windows body width should be greater than certain limit value, and rigidity and the unlikely weakening of bearing capacity of vertical wall are too much before could guaranteeing.But directly adopt the method that strengthens wall between windows body width will inevitably cause reducing of door and window hole area, thereby influence the daylighting demand of resident family.

In view of this, for addressing the above problem, namely do not reducing substantially under the prerequisite of door and window hole area, vertical wall has certain rigidity and shear-carrying capacity, improves the masonry house anti-seismic performance before making, this creator is according to theory analysis and practical experience, after deliberation, exploitation and through verification experimental verification, and have eventually the utility model to produce.

The utility model content

The utility model is that a kind of steel concrete doorframe and window frame will be provided, and makes it be applicable to that the wall body door or window hole area is excessive, interfenestration is less, the door and window size is various with solution, and improves the technical problem of the steel concrete doorframe and window frame of masonry house anti-seismic performance.

It is such solving the problems of the technologies described above the technical scheme that adopts:

A kind of reinforced concrete doorframe and window frame includes a sealing framework, and it is characterized in that: this sealing framework all is provided with a L shaped steel reinforced concrete prefabricated component for four jiaos, is provided with reinforced concrete cast-in-situ spare between the L shaped steel reinforced concrete prefabricated component on its four limit;

Those L shaped steel reinforced concrete prefabricated components are provided with a plurality of perforation, and those perforation are equiped with body of wall all around and are fixedly coupled part, and those L shaped steel reinforced concrete prefabricated component two-port are provided with flute profile tongue and groove and a plurality of protruding bar;

Those reinforced concrete cast-in-situ spares include a reinforcing cage, the protruding bar overlap joint of this reinforcing cage and L shaped steel reinforced concrete prefabricated component, this reinforcing cage is provided with the tension rib that is connected with body of wall, and this reinforced concrete cast-in-situ spare two-port is provided with the convex tongue and groove with the flute profile tongue and groove interlock of L shaped steel reinforced concrete prefabricated component two-port.

This a kind of steel concrete doorframe and window frame, include four L shaped reinforced concrete precast members and four reinforced concrete cast-in-situ sections, wherein those reinforced concrete precast members are fixed by connector and body of wall all around, the reinforcing cage of assembling reinforcement concrete cast-in-situ spare then, and with the protruding bar of reinforcing cage and prefabricated component overlap joint, simultaneously, those reinforcing cages are provided with tension rib and are connected with body of wall; Build the concrete of each reinforced concrete cast-in-situ spare at last, with the tongue and groove interlock of reinforced concrete precast member, form the sealing framework.

This steel concrete doorframe and window frame self rigidity is bigger, for the excessive masonry house of wall body door or window hole area, can improve rigidity and the shear-carrying capacity of the body of wall that punches greatly, reduce the torsional effect adverse effect under the geological process, improve the whole anti-seismic performance in house, its simple structure, easy construction, the duration is short, solve the diversity of different door and window sizes, had practicality.

The utility model is simple in structure, and its advantage is as follows:

1, steel concrete doorframe and window frame self rigidity is bigger, is not reducing substantially under the prerequisite of former door and window hole area, the antidetonation bearing capacity of eaves body of wall before guaranteeing.

2, the highly versatile of L type reinforced concrete prefabricated component can adapt to the big requirement of different door and window hole change in size in the actual building, and the bight cast in situs difficulty of construction of its steel concrete doorframe and window frame is big, difficult quality guarantee, by the prefabricated component assembling, ensure the quality of products, raise the efficiency.

3, simple structure, easy construction, the duration is short, is fit to industrialized implementation.
