Description

Technical Field

[0001] This utility model relates to the field of precast floor slab technology, specifically to a prefabricated lightweight core mold precast ribbed hollow floor slab. Background Technology

[0002] Hollow core slabs are a type of cast-in-place reinforced concrete hollow core slab, also known as cast-in-place flat slabs. They are formed by casting in place after installing core molds, creating a hollow, beam-free slab. Hollow core slabs are mainly composed of steel bars, concrete, and core molds, with lightweight materials filling the core molds. However, existing precast slabs, due to their conventional land-based construction methods, often fail to provide adequate shock absorption in earthquake-prone areas. This makes them prone to collapse, potentially leading to greater personal injury or property damage.

[0003] Application number CN202020592455.8 discloses a prefabricated lightweight core molded ribbed hollow floor slab structure, including top reinforcing bars, bottom reinforcing bars, and a filler. The filler is installed between the top and bottom reinforcing bars. The top of the filler is provided with anti-buoyancy reinforcing bars, which are locked in a slot on the top surface of the filler. A first pad is provided between the filler and the bottom reinforcing bars. Both the top and bottom reinforcing bars are composed of two sets of reinforcing bars arranged horizontally and vertically to form a reinforcing mesh.

[0004] The above patents still have some shortcomings: they improve the tightness of concrete pouring between the boxes in the hollow floor slab through structural design, but ignore the impact of natural disasters such as earthquakes on the floor slab, making them unsuitable for building construction in earthquake-prone areas and lacking in safety performance. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide a prefabricated lightweight core molded ribbed hollow floor slab, which can improve the building prestress of the floor slab, thereby improving the buffering and shock absorption capacity against disasters such as earthquakes.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A prefabricated lightweight core molded ribbed hollow floor slab includes several supports. Each support has an auxiliary beam fixedly connected to its middle position. Several main beams are fixedly connected to the upper surface of each auxiliary beam. Several base plates are fixedly connected to the upper surface of each main beam. A sliding seat is slidably connected to the top of each support. The sliding seat is detachably connected to the auxiliary beam through an adjustment component. Adjacent auxiliary beams are also detachably connected to each other through an adjustment component. The adjustment component includes two adjustment seats, which are detachably connected to each other through a steel wire rope.

[0008] The following are further optimizations of the above technical solution by this utility model:

[0009] The auxiliary beams are arranged in parallel and at intervals, the main beams are arranged perpendicular to the auxiliary beams, and the main beams are arranged in parallel and at intervals.

[0010] Further optimization: Several locking holes are spaced apart on one side of the upper end of the bracket, and a circular screw hole is opened on the side of the slide that contacts the bracket and is close to the locking holes. The locking holes and the circular screw hole are matched. A first connecting plate is provided on each of the two sides of the slide that correspond to the two ends of the auxiliary beam.

[0011] Further optimization: The lock hole is threaded with a bolt, which passes through the lock hole and is threaded into the circular screw hole on the slide.

[0012] Further optimization: A tripod is provided on the lower surface of the auxiliary beam near the support, and a second connecting plate is integrally provided on both sides of the tripod. The tripod is fixedly connected to the support by screws.

[0013] Further optimization: Both ends of the upper surface of the auxiliary beam are integrally provided with a third connecting plate.

[0014] Further optimization: Through holes are provided on the first connecting plate, the second connecting plate and the third connecting plate.

[0015] Further optimization: The adjusting seat has internal threaded holes at both ends. One internal threaded hole is threaded with a threaded hook, and the other internal threaded hole on the adjusting seat is threaded with a screw shaft, which is fixedly connected to the wire rope.

[0016] Further optimization: The threaded hook is used to attach to the through holes opened in the first connecting plate, the second connecting plate and the third connecting plate.

[0017] This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. The screw shaft is installed at the end of the corresponding adjustment seat and connected to the steel wire rope. The end of the adjustment seat away from the steel wire rope is threaded to the hook. By installing the hook at the end of the surface of the auxiliary beam or support structure, the overall device can be flexibly controlled, which enhances the practical performance of the overall device and improves the defects of existing precast floor slabs, which are mostly rigid structures with insufficient prestress during construction. It also enhances the buffering and shock absorption capacity in the event of earthquakes.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

Specific implementation mode

[0024] As Figure 1-4 shown: An assembled lightweight core mold precast ribbed hollow floor slab includes several supports 1. An auxiliary beam 8 is fixedly connected to the middle position of each support 1. Several main beams 9 are fixedly connected to the upper surface of each auxiliary beam 8. Several base plates 10 are fixedly connected to the upper surface of the main beams 9. A sliding seat 3 is also slidably connected to the top end of each support 1. The sliding seat 3 is detachably connected to the auxiliary beam 8 through an adjusting component. The adjacent auxiliary beams 8 are also detachably connected through the adjusting component. The adjusting component includes two adjusting seats 6, and the two adjusting seats 6 are detachably connected through a steel wire rope 7.

[0025] The several auxiliary beams 8 are arranged in parallel and at intervals. The main beams 9 are arranged perpendicular to the auxiliary beams 8, and the several main beams 9 are arranged in parallel and at intervals.

[0026] With such a design, the several auxiliary beams 8 and the several main beams 9 are arranged in a "field" - shaped staggered pattern, which is convenient for laying and installing the base plate 10.

[0027] A plurality of lock holes 2 are spacedly opened on one side surface of the upper end of the support 1. A circular screw hole is opened on the side surface of the sliding seat 3 that contacts the support 1 and is close to the lock hole 2. The lock hole 2 and the circular screw hole are matched. Two first connecting plates 12 are provided on the two side surfaces of the sliding seat 3 corresponding to the two ends of the auxiliary beam 8.

[0028] A bolt 4 is threadedly inserted into the lock hole 2, and the bolt 4 passes through the lock hole 2 and is threadedly connected to the circular screw hole on the sliding seat 3.

[0029] Tripods 11 are provided at the positions of the lower surface of the auxiliary beam 8 close to the supports 1. Second connecting plates 13 are integrally provided on both sides of the tripods 11. The tripods 11 are fixedly connected to the supports 1 through screws.

[0030] This design, through the tripod 11, can improve the tightness of the connection between the support 1 and the auxiliary beam 8, thereby improving the overall seismic resistance.

[0031] Both ends of the upper surface of the auxiliary beam 8 are integrally provided with a third connecting plate 14.

[0032] Through holes are provided on the first connecting plate 12, the second connecting plate 13 and the third connecting plate 14.

[0033] The adjusting seat 6 has internal threaded holes at both ends. One internal threaded hole is threaded to a threaded hook 15, and the other internal threaded hole on the adjusting seat 6 is threaded to a screw shaft 5. The screw shaft 5 is fixedly connected to the wire rope 7.

[0034] The threaded hook 15 is used to attach to the through holes opened in the first connecting plate 12, the second connecting plate 13 and the third connecting plate 14.

[0035] This design, through the cooperation of steel wire rope 7 and screw shaft 5, can provide a pre-tension between auxiliary beam 8 and support 1, and can also provide a pre-tension between auxiliary beams 8.

[0036] In use, first connect the threaded hook 15 and the wire rope 7 to the adjusting seat 6 to form an adjusting assembly. Then, suspend the adjusting assembly on the first connecting plate 12 and the third connecting plate 14 on the slide 3. At the same time, the second connecting plates 13 between adjacent auxiliary beams 8 are also connected by the connecting assembly. The cooperation between the slide 3 and the bolt 4 can change the position of the slide 3 in the bracket 1, thereby changing the traction force on the wire rope 7.

[0037] By adjusting the coordination between components, the overall control can be effectively improved, and the defects of insufficient prestress in the current floor slab construction process can be addressed, thereby enhancing seismic performance.

[0038] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
