Description

Frame-shear structure building large cantilever plate type balcony

Technical Field

The utility model belongs to building structure designs the field, especially relates to a frame shear structure building board-like balcony of encorbelmenting greatly.

Background

The frame shear wall is also called a frame shear structure and comprises two upright posts and a plurality of cross beams with different layer heights, wherein two ends of each cross beam are fixed with the two upright posts, the layer number is counted from the ground, for the first layer, the ground, the two sections of upright posts of the layer and the cross beam of the first layer form a frame unit, for the other layers, the cross beam of the next layer, the cross beam of the layer and the two sections of upright posts of the layer form a frame unit, and a wall concrete unit is poured in each frame unit. The floor slabs on each layer and the cross beams on each layer are integrally cast and molded, and the top elevation of each floor slab is flush with the top elevation of each cross beam. Because of the reliability of the building main body structure of the frame shear structure in the aspects of earthquake resistance and supporting strength, a bold overhanging structure is often adopted in the design of auxiliary structures so as to meet the more and more selected aesthetic requirements of consumers.

The overhanging balcony refers to a balcony with the whole or multiple parts extending out, and the outermost edge has no bearing wall or pillar, and the bearing is carried out by a floor slab or cantilever beams are arranged at the two ends of the balcony. The large cantilever balcony is generally formed by adopting a mode of cantilever concrete structural beams, and the large cantilever is difficult to realize by purely using structural slabs. The cross section of the overhanging balcony beam with the beam is higher, which can cause the lines of the outer vertical surface to be thicker and not fine enough, and influence the integral effect and aesthetic feeling of the whole building. If the conventional floor slab is adopted for cantilever, the thickness of the slab is very thick, the self weight is large, and the deflection and the cracks are difficult to control, so the difficulty is how to reduce the self weight of the cantilever slab and ensure the rigidity of the cantilever slab.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a frame shear structure building board-like balcony of encorbelmenting greatly that both weight is little and rigidity performance is good, its technical scheme as follows:

the large cantilever slab balcony with the frame shear structure comprises a load-bearing slab layer, a bearing concrete layer and a waterproof concrete layer which are sequentially arranged from bottom to top, wherein a reinforcement cage which is shared with a corresponding floor bearing plate and is integrally cast in situ is fixedly embedded in the bearing concrete layer, and the bottom surface of the bearing concrete layer is provided with a wavy bottom surface extending along the wall length direction; the inner side part of the load-bearing plate layer extends into a room and is connected with a reinforcement cage in the floor bearing plate, and the outer side part of the load-bearing plate layer is pressed, bent and attached to the lower part of the wavy bottom surface in a matched manner; the waterproof concrete layer is cast on the top surface of the bearing concrete layer in situ, and the top surface of the waterproof concrete layer is a plane or an inclined plane which inclines downwards from the inner side. Utilize the wave ground that bears the weight of the concrete layer to subtract heavy structure, reduce the weight of whole balcony, the setting on load plate layer can play the bearing effect in the balcony bottom surface simultaneously, strengthens the support rigidity of whole balcony to reduce weight under the condition that keeps balcony self rigidity, improved the practicality.

Further, the loading plate layer and the bearing concrete layer incline outwards gradually from the inner side at the same angle, and the inclination angle is 5-10 degrees.

Furthermore, the top surface of the bearing concrete layer is provided with criss-cross notches, and the notches are dovetail grooves or T-shaped grooves or major arc grooves, the opening degree of which is gradually reduced from the bottom of the groove to the opening of the notch.

Furthermore, the waterproof concrete layer is made of lightweight concrete.

Furthermore, embedded pipes made of engineering plastics and extending along the wall length direction are embedded in the waterproof concrete layer, embedded steel bars embedded in the waterproof concrete layer are arranged around the embedded pipes in a surrounding mode, and the pipe diameters of the embedded pipes are gradually reduced from the inner side of the waterproof layer to the outer side of the waterproof layer.

Detailed Description

Referring to fig. 1 and 2, the structural schematic diagram of the middle frame shear structure building large cantilever slab balcony of the present invention is shown. This frame shear structure building board-like balcony of encorbelmenting greatly adopts the cast-in-place structure of concatenation formula, and each layer all is connected or integrated into one piece with corresponding floor carrier plate, mainly comprises load plate layer 1, bearing concrete layer 2 and waterproof concrete layer 3 that set gradually from bottom to top promptly.

The load-carrying plate layer 1 is a wavy profiled steel plate and consists of a horizontal section positioned on the inner side and an upward inclined section positioned on the outer side. The horizontal section extends into the room and is statically connected with a reinforcement cage in the floor bearing plate. The upward inclined section is wave-shaped and gradually inclines upwards from the inner side to the outer side, and the inclination angle is 5-10 degrees.

Referring to fig. 3, a reinforcement cage shared with a floor bearing plate of a corresponding floor is fixed in the bearing concrete layer 2 in a pre-embedded manner, and the reinforcement cage is fixed in the bearing concrete layer 2 in a cast-in-situ manner. The bottom surface of the bearing concrete layer 2 is provided with a wave-shaped bottom surface 21 extending along the length direction of the wall, the wave-shaped bottom surface 21 is matched and attached with the upward inclined section of the bearing plate layer 1, the upper inclined angle of the outer side part of the bearing concrete layer 2 is the same as the inclined angle of the upward inclined section of the bearing plate layer 1, and the two are matched and attached together. The top surface of the bearing concrete layer 2 is provided with criss-cross notches 22, and the notches 22 are dovetail grooves or T-shaped grooves or major arc grooves with the opening degree gradually decreasing from the bottom of the groove to the opening of the groove.
