Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete panels, in particular to a high-strength assembled composite panel. Background Art

[0002] Existing high-strength composite panels have improved their strength, rigidity and temperature resistance by adding glass fiber to concrete, thereby greatly increasing the service life of the composite panels.

[0003] However, the composite slab is a precast concrete slab. During actual use, the protective layer thickness of the composite slab may be insufficient, which may cause the steel bars inside the composite slab to be easily exposed. This problem mainly occurs when the pads placed at the bottom of the horizontal and vertical steel bars fall off or fall over during the casting of the composite slab, thereby shortening the distance between the bottom end of the horizontal and vertical steel bars and the inner wall of the casting mold, which in turn leads to insufficient thickness of the protective layer. Utility Model Content

[0004] The purpose of the present invention is to provide a high-strength assembled composite plate to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-strength prefabricated composite slab, comprising a precast concrete slab, wherein transverse and longitudinal steel bars are provided inside the precast concrete slab for enhancing the rigidity of the precast concrete slab, and further comprising:

[0006] Spacers, used to support transverse and longitudinal reinforcements;

[0007] A fixing assembly, which is used to prevent the pad from tipping over. The fixing assembly includes an interpenetrating ring and an inserting block. The interpenetrating ring is used to be installed with the transverse steel bar, and the inserting block is used to connect with the pad. The bottom end of the interpenetrating ring is provided with a connecting piece for connecting with the inserting block, and the outside of the inserting block is provided with a barb piece for preventing the inserting block from falling off.

[0008] A slot, which is provided on the outer wall of the spacer and is used for installing the insert;

[0009] A locking groove is provided inside the slot and is used to cooperate with the barb piece.

[0010] Preferably, the pad is arranged at the bottom end of the transverse steel bar, a groove is provided on the top of the pad, and the longitudinal steel bar is engaged with the groove of the pad.

[0011] Preferably, the insertion ring is sleeved on the outer wall of the transverse steel bar, and the connecting piece includes a connecting rod, and the two ends of the connecting rod are fixedly connected to the bottom end of the insertion ring and one side of the insertion block respectively.

[0012] Preferably, the vertical cross-section of the connecting rod is L-shaped.

[0013] Preferably, the barb comprises a locking angle, and the locking angle is provided at the end of the insert block.

[0014] Preferably, the vertical cross-section of the insert is arrow-shaped, and the vertical cross-section of the locking angle is tooth-shaped.

[0015] Preferably, the vertical shape of the locking groove is a tooth shape.

[0016] The technical effects and advantages of this utility model are:

[0017] The utility model utilizes the design of a pad and a fixing assembly, wherein an interpenetrating ring is set on the outer wall of the transverse steel bar, and then the insert block is inserted into the interior of the slot. At this time, the locking angle will be squeezed by the inner wall of the slot. As the insert block moves, when the locking angle moves to the locking slot position, the locking angle will rebound with its own restoring force, so that a card connection is formed between the locking angle and the locking slot, thereby preventing the insert block from sliding out of the interior of the slot, realizing the anti-dumping effect of the fixing assembly on the pad block, and ensuring the thickness of the protective layer of the concrete precast panel.

[0026] Spacer 4, which is used to support the transverse reinforcement 2 and the longitudinal reinforcement 3;

[0027] The fixing assembly 5 is used to prevent the spacer 4 from tipping over. The fixing assembly 5 includes an interpenetrating ring 51 and an inserting block 53. The interpenetrating ring 51 is used to be installed with the transverse reinforcement 2, and the inserting block 53 is used to connect with the spacer 4. The bottom end of the interpenetrating ring 51 is provided with a connecting piece for connecting with the inserting block 53, and the outside of the inserting block 53 is provided with a barb piece for preventing the inserting block 53 from falling off.

[0028] Slot 6, which is provided on the outer wall of the spacer 4 and is used for mounting the insert 53;

[0029] The locking groove 7 is provided inside the slot 6 and is used to cooperate with the barb piece.

[0030] Specifically, the transverse steel bars 2 and the longitudinal steel bars 3 are existing steel bars, and multiple transverse steel bars 2 and longitudinal steel bars 3 are respectively arranged in the horizontal direction and distributed at equal intervals in a grid shape. The precast concrete panel 1 is a concrete composite panel formed after the precast concrete formwork is poured.

[0031] Specifically, the pad 4 is arranged at the bottom end of the transverse steel bar 2, a groove is provided on the top of the pad 4, the longitudinal steel bar 3 is engaged with the groove of the pad 4, and the vertical shape of the locking groove 7 is a tooth shape.

[0032] Furthermore, the pad 4 is an existing concrete pad, which is used to support the transverse steel bars 2 and the longitudinal steel bars 3, so that the longitudinal steel bars 3 and the transverse steel bars 2 have a certain distance from the bottom end of the inner wall of the formwork, so that a protective layer is formed as the concrete is poured. Two slots 6 are opened, one on each side of the outer wall of the pad 4. The slots 6 are used to insert the insertion block 53 while allowing the connecting rod 52 to move. The size of the locking groove 7 is 1.02 times the size of the locking angle 54.

[0033] Specifically, the interpenetrating ring 51 is sleeved on the outer wall of the transverse steel bar 2, and the connecting part includes a connecting rod 52. The two ends of the connecting rod 52 are fixedly connected to the bottom end of the interpenetrating ring 51 and one side of the insert block 53 respectively.

The plug block 53 and the locking angle 54 are integrally formed, and the plug block 53 and the locking angle 54 are made of rubber.

[0035] When arranging the transverse reinforcement 2 and the longitudinal reinforcement 3, the fixing components 5 are arranged in advance according to the required number of pads 4, and the inserted ring 51 is sleeved on the outer wall of the transverse reinforcement 2. Then, after the pad 4 is placed, the insert 53 is inserted into the slot 6, so that the locking angle 54 outside the insert 53 is moved to the position of the locking groove 7, so that the squeezed and deformed locking angle 54 is restored to its original shape, thereby forming a card connection between the locking angle 54 and the locking groove 7, and at the same time, one end of the insert 53 is tightly fitted with one end of the slot 6. Through the mutual cooperation of the locking angle 54 and the insert 53, the pad 4 cannot be tilted, so that the thickness of the protective layer of the concrete precast panel 1 can be guaranteed when pouring concrete.
