Multi-ribbed composite wallboard internally provided with special-shaped filling building blocks

Abstract

The invention provides a multi-ribbed composite wallboard internally provided with special-shaped filling building blocks; the multi-ribbed composite wallboard comprises rib beams (1), rib columns (2), the special-shaped filling building blocks (3) and a flexible filling material (6), wherein the rib beams (1) and the rib columns (2) form sashes; each sash is provided with a special-shaped filling building block (3) which comprises an upper special-shaped filling building block (4) and a lower special-shaped filling building block (5); the upper special-shaped filling building block (4) and the lower special-shaped filling building block (5) are meshed at a contact surface of the upper special-shaped filling building block (4) and a lower special-shaped filling building block (5); the upper special-shaped filling building block (4) and a lower special-shaped filling building block (5) horizontally and relatively slide under the action of external force; and the flexible filling material (6) is filled in gaps among the special-shaped filling building blocks (3) and the rib columns (2). The multi-ribbed composite wallboard not only can increase the frictional energy consumption effect of multi-ribbed composite walls and reduce the seismic response of the multi-ribbed structure, but also can avoid the condition that excessive building blocks are filled in the sashes, avoid the occurrence of external plane dropping of the sashes and ensures the whole service behavior of the building blocks in the sashes.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a dense-ribbed composite wallboard with built-in special-shaped filling blocks. Background technique [0002] The patent application text of Chinese Invention Patent Publication No. 200610001006.6 discloses a new type of structure named "Micro-rib structure system and its connection construction method". The ribbed structural system of the invention includes a ribbed composite wall panel, an invisible frame and a floor slab. Ribbed composite wall panels (also known as densely ribbed composite walls) are grid-shaped building components made of reinforced concrete rib beams, rib columns and lightweight filled blocks. Concrete beam-column rib beam-column divisions are formed by embedding lightweight material infill blocks in the lattice. The anti-seismic performance and energy consumption performance of this technology are relatively poor. [0003] In order to enhance...

Problems solved by technology

However, since the filling blocks are all brittle materials, their energy dissipation capacity is limited

[0006] (2) From the perspective of engineering practice, when designing and constructing existing densely ribbed composite wall structures, the most common practice is to set two filling blocks inside a grid, and set three or three filling blocks inside a grid. The practice of filling blocks above the block does not conform to the experience of engineering practice, and the construction is inconvenient, and the more filling blocks are set inside a grid, the more troublesome the construction

[0007] (3) Practice has proved that the larger the number of filling blocks in a grid and the smaller the size of the filling blocks, the poorer the overall performance of the filling blocks, resulting in the more likely the filling blocks to fall out of plane under repeated seismic movements , once a filling block falls off, it will cause the surrounding filling blocks to fall off one after another, and the wall panel will lose its bearing capacity and energy dissipation capacity and be destroyed

[0008] (4) Since the earthquake action is a horizontal movement, there is basically no relative sliding of the filling blocks near the vertical joints formed in the longitudinal direction, and the setting of the vertical joints cannot achieve the effect of frictional energy dissipation. On the contrary, the filling blocks will Vertical joints are set between the blocks, which is equivalent to the early cracking of the filling blocks at this position, resulting in a reduction in the bearing capacity and stiffness of the wall panel. The more vertical joints are set, the more the bearing capacity and stiffness of the wall panel are reduced.

[0009] (5) When designing and constructing according to the traditional method, the contact between the filling block and the concrete rib beam is in a planar manner, and cracks are very easy to appear under the action of the earthquake, and sliding occurs between the filling block and the concrete rib beam. Although the amount is small, it affects the overall performance of the filled blocks and sash

[0010] The above shortcomings make it difficult to apply frictional energy-dissipating densely ribbed composite wall panels in engineering, and their actual energy-dissipating and shock-absorbing effects are relatively limited.
