Description

Technical Field

[0001] The utility model relates to the technical field of building processing equipment, in particular to a rotatable prefabricated concrete slab foundation for a building safety passage. Background Art

[0002] With the development of modern construction industry, various places and enterprises have put forward higher and higher requirements and standards for safe and civilized construction. As an indispensable part of on-site safety and civilization, the importance of building safety passage is self-evident. Building safety passage is not only a safety guarantee passage for construction site workers to enter and exit the building, but also an important way for small working vehicles, machinery and materials to enter the building. In the past construction process, the foundation of the safety passage often adopts on-site concrete construction. This method has two main disadvantages. First, cast-in-place concrete construction requires manual formwork, steel bar binding, concrete pouring and other processes. After pouring, it usually takes more than a few days for the concrete to be strong enough to allow vehicles to pass, so the efficiency is low; second, at the end of construction, the foundation of the on-site safety passage can only be used once, and it needs to be broken after the construction is completed. Not only can it not be turned over, but it will also generate a lot of demolition and construction waste removal costs, which is relatively wasteful and not economical.

[0003] That is to say, the existing technology of using on-site casting to make the concrete precast slab foundation easily leads to the problem of prolonged traffic time and the inability to recycle the concrete precast slab foundation. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a rotatable precast concrete slab foundation for a safe passage into a building, which solves the problems of prolonged traffic time and inability to rotatably use the precast concrete slab foundation caused by on-site casting of the precast concrete slab foundation.

[0015] In one embodiment, a portion of the second connection assembly is embedded in one of two adjacent prefabricated panels, and another portion of the second connection assembly is plug-fitted with the other prefabricated panel.

[0016] In one embodiment, the second connection component includes:

[0048] Specifically, Figures 1 to 6 As shown, in one embodiment, the first connecting assembly 20 is constructed as an integral bent tube formed by bending a round tube.

[0049] It should be noted that the prefabricated main body foundation plate (prefabricated plate 10), as the main body of the safety channel concrete prefabricated plate foundation, has a rectangular cross-section and mainly bears the upper load of the safety channel; the special lifting ring (second connecting component) is embedded in the prefabricated main body foundation plate and is used for lifting work during the turnover process; the U-shaped plate connector (first connecting component) cooperates with the reserved PVC sleeve on the prefabricated main body foundation plate as a detachable and turnover temporary fixing device, which is used to connect and fix adjacent safety channel concrete prefabricated plate foundations; the protruding part of the special lifting ring can penetrate into the groove of the lifting ring to ensure a tight connection, and at the same time play a role in fixing adjacent plates.

[0050] Specifically, the foundation of the recyclable concrete precast slab is prefabricated in a factory or construction site. After completion, it is transported to the designated location through a safe passage by vehicles and assembled in place using a lifting and hoisting machine. The process is: leveling the ground of the prefabrication site → supporting the formwork → tying the steel bars → installing the embedded parts → pouring the concrete → curing → removing the formwork.

[0051] Before installing the rotatable precast concrete slab foundation for the safe entrance to the building in this application, the foundation must be leveled and compacted, and the overall drainage design slope on site must be verified. The ring knife method must be used to test the foundation bearing capacity to ensure that the foundation elastic modulus is ≥40Mpa.

The modulus of a single recyclable precast concrete slab foundation of the building entrance safety passage is 2m long and 1.5m wide, which can be spliced ​​and combined into safety passages of different sizes such as 2m×3m, 4m×6m, 7.5m×10m, etc. The specific size of the anti-smashing shed of the upper safety passage can also be combined as its column foundation, and the anti-smashing shed of the safety passage can be fixed to the foundation with expansion bolts, etc.

[0053] During installation, first locate and lay out the position of the prefabricated main body foundation plate, and then hoist and secure each prefabricated main body foundation plate from one side to the other. The special hoisting ring and the hoisting ring groove are interlocked in sequence. After all the plates are hoisted into place, install the U-shaped plate connector to connect the prefabricated main body foundation plates into a whole.

[0054] When dismantling, first remove the U-shaped plate connector, and then lift and remove the prefabricated main foundation plate from one side to the other.
