Embodiment Construction
[0038] like figure 1 and figure 2 As shown, the roof reserved hole construction mold includes a casing structure placed on the bottom formwork 1 of the floor slab, and a fixed support frame inserted in the casing structure and connected to the bottom formwork 1 at the lower end.
[0039] like Figure 4 and Figure 5 As shown, the sleeve structure is composed of an inner sleeve 4, an outer sleeve 3 and an outer ring 2, the inner sleeve 4 is provided with an axial through-length gap 11, and the outer sleeve 3 is provided with an axial The gap 2 12 is long, the outer ring 2 is provided with an axial through slit 13, the outer sleeve 3 is set on the outside of the inner sleeve 4 and is in contact with the inner sleeve 4, the outer ring 2 is sleeved on the outer sleeve The outer side of the tube 3 is in surface contact with the outer tube 3 .
[0040] like Image 6 As shown, the fixed support frame includes a threaded screw 5, an operating handle 6 rigidly connected to the to...

The invention relates to a top plate reserved hole construction form and a construction method thereof. The top plate reserved hole construction form comprises a sleeve pipe structure and a fixing support frame, wherein the sleeve pipe structure is arranged on a slab bottom formwork; the fixing support frame is inserted into the sleeve pipe structure, and the lower end of the fixing support frame is connected with the slab bottom formwork; the sleeve pipe structure consists of an inner sleeve pipe, an outer sleeve pipe and an outer ring; the fixing support frame comprises a through-thread screw rod, an operation handle, a nut, an upper cover plate and a lower support plate, the operation handle is rigidly connected with the top part of the through-thread screw rod, the nut is tightened to the through-thread screw rod, and the upper cover plate and the lower support plate penetrate into the through-thread screw rod under the nut. The top plate reserved hole construction form has the advantage that when a roofing reserved hole is constructed, the sleeve pipe structure is fixedly arranged at the marked part on the slab bottom formwork by the fixing support frame, so that the watching by special persons is not needed after the sleeve pipe is installed, a large amount of labor is saved, and the technical problems of waste of a large amount of labor, uncontrollable detachment time of sleeve pipes, and higher construction cost in the traditional construction method are solved.
Description
technical field [0001] The invention relates to a mold used in the construction of reserved holes and a construction method thereof. Background technique [0002] At present, when constructing the reserved holes of the suspended ceiling, the most commonly used method is to bind the steel pipes on the steel mesh when constructing the floor steel mesh, then pour the floor concrete, and remove the steel pipe casing after the floor concrete reaches a certain strength. This method does not require special construction molds with holes reserved, but this method has the following disadvantages: 1. The casing is bound on the steel mesh, and the steel pipe casing has to be taken care of by a special person, so a lot of labor is wasted; 2. Dismantling It is difficult to control the timing of the casing. If the steel pipe casing is removed too early, the concrete hole will easily collapse. If the steel pipe casing is removed too late, the casing cannot be taken out; 3. The casing mater...
