Detailed Description
As shown in fig. 1 and 2, the light-weight preformed hole aluminum mold box comprises a frame box with a cavity, wherein the frame box comprises an upper frame body 110 and a lower frame body 120, the upper frame body 110 and the lower frame body 120 are both in inverted frustum structures with large upper parts and small lower parts, the outer wall of the frame box is provided with a yielding step 130, the yielding step 130 is positioned at the joint of the upper frame body 110 and the lower frame body 120, and the step surface of the yielding step 130 faces downwards;
go up framework 110 and lower framework 120 and all include strengthening layer 710, interior aluminum sheet layer 720 and outer aluminum sheet layer 730 establish respectively at the inside and outside two sides of strengthening layer 710, strengthening layer 710 is formed by two-layer honeycomb layer 711 complex that has honeycomb structure, the upper and lower symmetric distribution of honeycomb structure of two honeycomb layers 711, honeycomb structure includes the honeycomb unit 712 of a plurality of round platform form, the relative setting of top surface that the honeycomb unit 712 one-to-one of two honeycomb layers 711 just.
When needing to set up the preformed hole, place the frame case in the corresponding position of floor board, pour the concrete again around the frame case, take out the frame case after concrete floor 800 solidifies and can accomplish the setting of preformed hole, the use that the frame case can relapse has improved the efficiency of construction. Go up framework 110 and lower framework 120 and all adopt big-end-up's back taper platform structure, after the preformed hole shaping, the frame case is taken out from concrete floor 800 more easily, the design of step 130 of stepping down for the concrete can play the supporting role to the frame case in step 130 department of stepping down, prevents that the frame case from appearing the sunken condition in the forming process of preformed hole, has improved the shaping quality of preformed hole.
Go up framework 110 and lower framework 120 and use the middle double-deck honeycomb layer 711 that has honeycomb structure as the main part to at honeycomb layer 711 two-sided interior aluminum plate layer 720 and outer aluminum plate layer 730, have the characteristics that the quality is light, intensity is high, be convenient for constructor's removal and installation to the frame case, provide the efficiency of construction.
Further, the upper frame 110 and the lower frame 120 are each configured in a rectangular pyramid shape having a large top and a small bottom. The upper frame body 110 and the lower frame body 120 are both designed to be quadrangular frustum pyramid-shaped structures, which is beneficial to construction convenience, and can be designed to be structures of other forms, such as circular truncated cones and the like.
Furthermore, the peripheral surface of the lower end surface of the upper frame 110 is larger than the peripheral surface of the upper end surface of the lower frame 120, and a "return" abdicating step 130 is formed at the joint of the upper frame 110 and the lower frame 120.
The upper end surface of the lower frame body 120 is smaller than the lower end surface of the upper frame body 110 by one circle, so that a return-type abdicating step 130 is formed at the joint between the two sides, and the abdicating step 130 can also adopt other forms, for example, a group of abdicating steps can be arranged on a group of opposite outer walls of the frame box. When the back-shaped abdicating step 130 is provided with the preformed hole, the frame box is better positioned, and the problem that the preformed hole is inclined due to inclination offset when the frame box is placed is prevented.
The upper end surface of the upper frame 110 is provided with a removable cover 200. The movable cover plate 200 is arranged on the upper end face of the upper frame body 110, and when concrete is poured, the movable cover plate 200 covers the upper frame body 110, so that the concrete is prevented from entering the inner cavity of the frame box, and the inner cavity of the frame box is prevented from being polluted. When the inner cavity of the frame box needs to be operated, the movable cover plate 200 is opened.
At least one upper frame reinforcing rod 300 is arranged in the frame box of the upper frame body 110, and two ends of the upper frame reinforcing rod 300 are respectively connected to a group of opposite inner side walls of the upper frame body 110.
