Description
Technical Field
The utility model relates to a building structure technical field, especially a super high-rise building structure uses huge braced frame structure.
Background
With the continuous development of functions and forms of high-rise and super high-rise buildings in diversified directions, the application of the conversion layer is more and more extensive. The batter post conversion structure is provided with a conversion component which mainly bears axial load, has the characteristics of short force transmission path and smaller section size of the conversion component, is beneficial to the use of building space, and has wide application prospect. Furthermore, since the conversion member mainly bears an axial load, a concrete filled steel tube member is suitably used. The steel pipe concrete member is smaller than the traditional reinforced concrete member in size, saves templates, does not need to bind reinforcing steel bars, and has fast construction progress and guaranteed construction quality. When the batter post and the support post of the batter post conversion structure both adopt steel pipe concrete members, the batter post and the support post are called as a steel pipe concrete batter post conversion structure. The node is used as an important part in the steel pipe concrete inclined column conversion structure, the research results of the mechanical properties and the construction method are few, and the node becomes a bottleneck for restricting the application of the steel pipe concrete inclined column conversion structure.
According to different types of conversion components, the conventional batter post conversion structure nodes are mainly divided into three types, namely reinforced concrete batter post conversion nodes, section steel concrete batter post conversion nodes and steel tube concrete batter post conversion nodes.
1. Batter post conversion node of conversion component for reinforced concrete component
The inclined column and the support column are reinforced concrete members, the steel bars of the inclined column, the support column and the floor beam are intersected at a node, and concrete in the node area is formed by pouring and tamping at one time. The internal force of batter post, floor beam directly transmits to the node district through reinforcing bar and concrete, then transmits to the pillar, and the wholeness of node is good. However, there are disadvantages in practical applications, mainly:
(1) the cross section of the member is large in size, and the use of building space is influenced. The inclined column in the inclined column conversion structure bears the load transmitted by the upper structure, the internal force is larger, and the larger the inclination angle with the vertical direction is, the larger the internal force of the inclined column is. The bearing capacity of the reinforced concrete member is lower, and in order to meet the requirement of safety, the section size of the inclined column and the volume of the node are both larger, so that the use space of the transfer floor building is reduced, and the pipeline is inconvenient to pass.
(2) The construction difficulty of the node is high. Although the integrity of the reinforced concrete inclined column conversion node is good, the reinforcing steel bars of a plurality of inclined columns, pillars and floor beams are collected and anchored in a node area, the reinforcing steel bars in the node area are dense and difficult to bind, and the construction quality is difficult to ensure. The node area has large volume, the concrete tamping performance is difficult to ensure, and the hydration heat is high and the temperature stress is larger during pouring and tamping, which is unfavorable for crack control. In addition, the construction process of the concrete structure needs formwork erecting operation, and the construction period is long.
2. Inclined column conversion node with conversion component being steel reinforced concrete component
The inclined column and the support column are steel reinforced concrete members, the steel bars and the steel sections of the inclined column, the support column and the floor beam are intersected at a node, and concrete in the node area is formed by casting and tamping at one time. The internal force of batter post, floor beam directly transmits to the node district through shaped steel, reinforcing bar and concrete, then transmits to the pillar, and the wholeness of node is good.
The conversion member of the node adopts the steel reinforced concrete, and the section of the conversion member is smaller than that of the steel reinforced concrete member, thereby being beneficial to the use of building space. However, the nodes are provided with a plurality of inclined columns, the section steel and the reinforcing steel of the support and the reinforcing steel of the roof beam, the reinforcing steel in the node area is dense and difficult to bind, the construction difficulty is high, and the quality is difficult to ensure.
3. Batter post conversion node that conversion component is steel pipe concrete component
The batter post and the pillar all adopt the steel pipe concrete, and the floor beam generally adopts girder steel or shaped steel concrete beam, and the connected mode of roof beam and node is the same with general steel pipe concrete node. The vertical load is transmitted through the connection of the batter post and the support column, the beam end bending moment is transmitted through the inner partition plate or the outer reinforcing ring of the node, and the beam end shearing force is transmitted through the connection of the beam web and the support column or the batter post steel pipe. The concrete filled steel tube batter post conversion structure applied in engineering mainly has the following three types, and each type has advantages and disadvantages:
(1) the oblique column and the pillar are communicated with each other. The batter post and the pillar can be respectively a rectangular steel tube concrete column and a circular steel tube concrete column, and can also be circular steel tube concrete columns, so that the requirements on the section shapes of the members are low. The side of the pillar is provided with an opening, the batter post is connected with the pillar from the side of the pillar in a penetrating way, an inner partition plate or an outer ring plate is arranged in a node area, the floor beam is connected with the pillar in the node area or directly connected with the batter post, and the concrete of the batter post, the node and the pillar is poured and pounded at one time or in sections.
The holes made in the sides of the pillars weaken the pillar cross-section and complicate the stress distribution in the intersecting zones. The inner force of the inclined column is mainly axial force, and when the inner force is transmitted to the support column from the side surface, horizontal shearing component force and vertical shearing component force of the intersecting interface of the support column and the inclined column are generated on the support column. The horizontal shearing component force is borne by the shearing-resistant bearing force of the cross section of the strut or an inner partition plate of the node area, the vertical shearing component force is borne by the concrete shearing strength of a steel pipe welding seam and an intersecting interface, the force transmission path is clear, but the force transmission units are more, the stress distribution of the node area is complex, and a weak cross section is easy to form. The floor beam on the same plane with the batter post can only be connected with the batter post, but can not be directly connected with the pillar, which further causes the ambiguity of the force transmission of the node area. If the node area is connected with the floor beams in different directions through the outer ring plates, the range of the node area is greatly increased, and the appearance and the use of the building are influenced.
(2) The oblique column and the pillar are in butt joint type joint. The node is only suitable for the condition that the batter post and the pillar both adopt the concrete-filled steel tubular column with the rectangular cross section, and generally only 2 batter posts are connected. The cross section area of the pillar is equal to the total cross section area of the bottom of the intersection of the two batter posts, the lower ends of the batter posts are in butt welding with steel plates on each side of the pillar, the intersection of the batter posts is welded with a vertical partition plate, the vertical partition plate is welded with the inner side of a steel pipe of the pillar, an inner partition plate or an outer ring plate is arranged in a node area, a floor beam is connected with the pillar in the node area, and the concrete of the batter posts, the nodes and the pillar is poured and tamped at one time. The internal force of the batter post is directly transferred through the butted steel pipe and concrete, and the transferring mode of the internal force of the beam end of the floor beam is the same as that of a common steel pipe concrete node.
The node of the type ensures the integrity of the strut, and the force transmission path is simple and clear. However, when the connection mode is adopted, only concrete-filled steel tubes with rectangular cross sections can be adopted, and the rectangular steel tubes have poor constraint effect on core concrete and low economic benefit.
(3) The oblique column and the pillar of the inner partition plate are inserted into a node, and the oblique column and the pillar respectively adopt steel pipe concrete columns with rectangular and circular sections. The lower ends of the steel plates of the two inclined columns are respectively welded with the side faces of the vertical partition plates extending outwards from the node area and are in butt welding with the upper ends of the vertical rib plates of the node area; the vertical partition plate and the vertical rib plate are mutually welded, and the lower ends of the vertical partition plate and the lower inner partition plate are welded; the node area is respectively provided with an upper inner baffle and a lower inner baffle and an outer reinforcing ring at the positions corresponding to the heights of the upper flange and the lower flange of the floor beam; the floor beam is connected with the pillar in the node area; the concrete of the inclined column, the node and the supporting column can be cast and tamped at one time or in sections. The bending moment of the diagonal column end and the beam end is transmitted through the inner partition plate and the outer ring plate, the vertical load of the diagonal column is transmitted to the node area through the vertical partition plate and the rib plate, and then is transmitted to the strut in a local pressure mode through the lower inner partition plate and the concrete.
The node of this type has guaranteed the integrality of pillar, can realize being connected of rectangular cross section batter post and circular cross section pillar to do not influence upper portion building usable space, improve the bearing capacity of pillar, it is simple, clear and definite to pass the power route. However, the upper inner partition plate and the lower inner partition plate are arranged in the core area of the node, the welding workload is large, and when the cross section size of the strut is small, welding construction and concrete pouring are difficult, and the construction quality is difficult to guarantee.
