Description
Technical Field
The utility model relates to a building technical field, specific saying so relates to a connection structure of hollow partition plate of concrete and vertical fishplate bar.
Background
As a novel energy-saving wall material, the concrete hollow partition wall board has the advantages of light weight, high strength, multiple environmental protection, heat preservation, heat insulation, sound insulation, rapid construction, reduction of wall cost and the like, thereby gradually replacing the traditional masonry brick wall and being widely popularized and used in China. At present, the common thickness of the concrete hollow partition board is 90mm, 100mm, 120mm, 150mm and 200mm, the width is 600mm, and the length can reach 3000-3600 mm. The concrete hollow partition board has several vertical hollow holes in the cross section, and the partition boards of different thickness have different corresponding hollow hole diameters of 50-80 mm.
In different building projects, the building layer height should meet the use function requirements, the building layer height of a residential building is more about 3m, and in public buildings such as hospitals and schools, the building layer height is different from 3m to 6 m; and because concrete hollow partition wall board length is limited, when the higher building partition wall of some floor height uses, just need use vertical fishplate bar, two hollow wall boards are vertical to splice promptly and are satisfied the partition wall height requirement.
The vertical fishplate bar connected mode that hollow partition plate of concrete was commonly used at present has two kinds: 1) and when the height of the upper connecting plate is less than or equal to 1200mm, inserting an EPC foam rod into the top end of the hollow hole of the lower partition wall plate, uniformly wiping and scraping adhesive mortar on the width section of the EPC foam rod, installing the upper connecting plate, and adhering glass fiber gridding cloth along the middle joint after the wallboard is installed for 15 days. When the method is adopted for construction, the upper connecting plate has no fixing measure, is easy to move and difficult to install, is difficult to control the installation verticality and levelness of the wall plate, and has the defects of weaker connection performance of the upper wall plate and the lower wall plate and easy out-of-plane deformation under the action of external force; 2) when the height of the upper connecting plate is larger than 1200mm, holes in the middle of the cross section are selected, EPC foam rods are plugged into the positions, 150mm away from the top end, of the hollow holes of the lower partition plate, 2 reinforcing steel bars with the length of 300mm and the diameter of 6 or 8 are placed in the holes, cement mortar is filled in the holes, bonding mortar is smeared on the width cross section, the upper connecting plate is installed, the reinforcing steel bars extend into the holes in the upper portion, and after the wall plate is installed for 15 days, glass fiber gridding cloth is pasted along the middle seam. This way hopes to strengthen partition wall board connection from top to bottom through addding the reinforcing bar, can play a certain role relatively speaking, however reinforcing bar rigidity is less strong, and during installation upper portion fishplate bar, the reinforcing bar can not play effectual limiting displacement, and difficult control wallboard installation hangs down straightness, levelness to reinforcing bar length is longer, and it is great to stretch into upper portion fishplate bar construction degree of difficulty in the finite space.
It is obvious shortcoming all to see two kinds of fishplate bar processing methods at present, to how to strengthen connecting between the upper and lower wallboard, can solve again that the work progress in upper portion fishplate bar is spacing, reduce fishplate bar installation skew, promote upper portion fishplate bar efficiency of construction, this patent proposes the vertical fishplate bar of concrete hollow partition wall board and connects.
