Prefabricated honeycomb composite structure wallboard

Abstract

The invention discloses a prefabricated honeycomb composite structural wallboard which comprises a platy cubic wallboard body provided with at least six surfaces. A plurality of honeycomb structure units distributed in a honeycomb shape are arranged in the wallboard body. Each honeycomb structure unit comprises a polygonal honeycomb wall which is formed by connecting at least six edges or a tubular honeycomb wall composed of arc edges, a honeycomb hole and filler, wherein the honeycomb hole is formed by the honeycomb wall, and the filler is arranged in the honeycomb hole. The periphery of the honeycomb structure unit located in the middle is adjacent to at least four additional honeycomb structure units. The prefabricated honeycomb composite structural wallboard is easy and convenient to manufacture, the polygonal or arc-shaped honeycomb structure units formed by at least six sides are adopted and distributed in the wallboard in the honeycomb shape so that the wallboard of a composite structure can be formed, the bearing capacity of the assembled wallboard is improved so that the stress of the wallboard can be more uniform and reasonable, the safety performance of the wallboard is improved, and the economical efficiency is remarkable.

Problems solved by technology

They have the following disadvantages: (1) Because the prefabricated shear wall panels are all composed of concrete, the weight per unit volume is large (the weight of concrete is generally greater than 25kN / m 3 ), which brings difficulties to the transportation and hoisting of prefabricated components, so it is necessary to reduce the size of prefabricated components and increase the amount of on-site connection of prefabricated components. On the other hand, the project cost is relatively high

(2) The ribbed composite wallboard of the regulation JGJ / T275-2013 overcomes the above-mentioned shortcomings of the prefabricated shear wallboard, and its weight per unit volume is moderate (the weight of concrete is 10-17kN / m 3 ),like figure 1 shown; but its vertical bearing capacity and anti-sway stiffness are greatly reduced, (the main function of the structural wall is to bear vertical load and resist horizontal force)

(3) Patent No. 205530681U patent, which is a diagonal dense rib composite wallboard. The lateral movement resistance of the diagonal dense rib composite wallboard is strengthened. The bearing capacity varies from big to small, and the final comprehensive bearing capacity depends on the one with the smallest bearing capacity. In addition, because the oblique dense ribs cannot carry the vertical load equivalently to the vertical side ribs (that is, a vertical load occurs under the action of a vertical load). When the unit is deformed vertically, the bearing capacity of the vertical member is relatively large), the vertical side rib carries most of the vertical load, so the section of the vertical side rib needs to be enlarged, because the rib is not vertical and horizontal Set, under the action of vertical gravity (the force is the largest and always existing force of the building), additional stress is generated on the horizontal members (beams) and edge members (edge ​​columns) at the floor where the installation is located, such as in the column The horizontal force component generated at the connection between the layers and the diagonal ribs is unfavorable for earthquake resistance, and tension or compression is generated on the horizontal members, which increases the force on the horizontal members and edge members and complicates the structure, so that the densely ribbed composite wallboard of this design cost-effective

What is more unfavorable is that under the action of vertical load, due to the reduction of the sharing capacity of the diagonal rib, the edge member bears more, and the size of the edge column needs to be increased, thereby increasing the additional engineering cost (investment)
