Description

Technical Field

[0001] The utility model relates to a construction structure for hoisting and installing laminated plates, belonging to the technical field of laminated plate construction. Background Art

[0002] The prefabricated floor slab is composed of a precast laminated plate and a cast-in-place reinforced concrete layer laminated together. When the precast laminated plate is prefabricated and transported to the construction site, sometimes it is necessary to synchronously hoist two precast laminated plates.

[0003] For the hoisting of two precast laminated plates, see Chinese Patent Publication No. CN110422752B. Although two precast laminated plates are serially hoisted through two layers of hanging frames to achieve synchronous hoisting of the two precast laminated plates, after the two precast laminated plates in the serial hoisting state are hoisted in place, they cannot be synchronously lowered. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a construction structure for hoisting and installing laminated plates.

[0005] The utility model is achieved through the following technical solutions.

[0006] A construction structure for hoisting and installing laminated plates provided by the utility model includes:

[0007] Two spaced-apart laminated plates, and the two laminated plates are spaced apart by a laminated plate spacing component and are in the same horizontal state.

[0008] A hanging frame is spaced above the laminated plate. The bottoms of the four corners of the hanging frame are connected to the lifting ring screws through chain A. The lifting ring screws are screwed with the laminated plate. The hooks are connected to the tops of the four corners of the hanging frame through four chain B.

[0009] The laminated plate spacing component includes a screw rod, an outer clamping plate, a nut, an inner clamping plate, a double-headed telescopic member, and a mounting plate;

[0010] The screw rod is installed in the lifting ring screws on two different laminated plates. The outer clamping plate can be slidably sleeved on the end of the screw rod. The outer clamping plate is screwed on the screw rod through the nut. The two outer clamping plates can be clamped inwardly by the opposite forces to clamp the outsides of the two laminated plates;

[0011] Two inner clamping plates can be slidably sleeved on the middle of the screw rod. A double-headed telescopic member is installed between the inner clamping plates. The double-headed telescopic member is slidably installed on the screw rod through the mounting plate. After the two heads of the double-headed telescopic member extend, they push against the two inner clamping plates to contact the two laminated plates for spacing. One laminated plate is clamped by one inner clamping plate and one outer clamping plate; at this time, the two laminated plates are in a spaced state.

[0012] The laminated plate spacing components are two groups distributed at intervals.

[0013] The embedded screw sleeve in the laminated slab is screwed with the lifting ring screw; a through hole is provided on the lifting ring screw and is in interference fit with the screw rod.

[0014] A pull rope composed of a steel rope is fixed to the lifting ring screw, and a gourd damping member in the shape of a gourd is fixed to the top of the pull rope. The bottom of the gourd damping member penetrates through the through hole of the hanging bracket; the gourd damping member is made of elastic rubber, and the diameter of the multi-layer gourd shape of the gourd damping member is larger than the diameter of the through hole of the hanging bracket.

[0015] The beneficial effect of the present utility model is that: the two laminated slabs are ensured to be at the same horizontal state through the laminated slab spacing component. After presenting the laminated slab installation and lifting construction structure, the two laminated slabs are lifted synchronously from the placement point to the building installation point by the lifting hook and then lowered synchronously, which is beneficial to the synchronous assembly of the two laminated slabs and solves the problem that the two precast laminated slabs in the series hoisting state cannot be lowered synchronously after being hoisted in place.

Detailed Implementation Modes

[0019] The technical solutions of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0020] As Figures 1 to 2 shown.

[0021] A method for installing and constructing a laminated slab of the present application includes the following steps:

[0022] Assembly and installation: Above two laminated slabs 1 in the same horizontal state and spaced apart, there is a hanging bracket 2 at a distance. The bottom corners of the hanging bracket 2 are connected to the lifting ring screws 22 through the lifting chains A 21. Every two lifting ring screws 22 are screwed and fixed in the screw sleeves embedded in the laminated slab 1. The lifting hook 3 is connected to the top corners of the hanging bracket 2 through four lifting chains B 31;

[0023] The eyebolt 22 on two different laminated plates 1 is installed with a screw rod 4. The end of the screw rod 4 is slidably sleeved with an outer clamping plate 41. The outer clamping plate 41 is screwed onto the screw rod 4 through a nut 42. The two outer clamping plates 41 can be stressed towards each other to clamp the outer sides of the two laminated plates 1 inwardly; two inner clamping plates 43 are pushed outwards by a double-headed telescopic member 44 to press against the inner sides of the laminated plates 1, so that one laminated plate 1 is clamped by one inner clamping plate 43 and one outer clamping plate 41.

[0024] Two inner clamping plates 43 with a quantity of two are slidably sleeved on the middle part of the screw rod 4. A double-headed telescopic member 44 is installed between the inner clamping plates 43. The double-headed telescopic member 44 is a threaded double-headed telescopic member or a pneumatic double-headed telescopic member. The double-headed telescopic member 44 is slidably installed on the screw rod 4 through a mounting plate 45. After the two heads of the double-headed telescopic member 44 extend, they push against the two inner clamping plates 43 to contact the two laminated plates 1 for spacing, ensuring that the two laminated plates 1 are in a spaced state to present a lifting construction structure for hoisting the laminated plates.

[0025] The screw rod 4, the outer clamping plate 41, the nut 42, the inner clamping plate 43, the double-headed telescopic member 44, and the mounting plate 45 constitute a laminated plate spacing assembly. There are two groups of laminated plate spacing assemblies distributed at intervals. After the eyebolt 22 is screwed with the embedded screw sleeve of the laminated plate 1, when the two inner clamping plates 43, the mounting plate 45, and the two outer clamping plates 41 are distributed at the corresponding positions on the sides of the two laminated plates 1, the screw rod 4 passes through in sequence. The through hole provided on the eyebolt 22 through which the screw rod 4 passes is in interference fit to ensure that it cannot rotate randomly.

[0026] Both the inner clamping plate 43 and the outer clamping plate 41 are wooden boards, or the inner clamping plate 43 is a rubber plate and the outer clamping plate 41 is a steel plate.

[0027] The eyebolt 22 is fixed with a pulling rope 5 composed of a steel rope. The top of the pulling rope 5 is fixed with a gourd-shaped damping member 51. The bottom of the gourd-shaped damping member 51 penetrates through the through hole of the hanging frame 2. The gourd-shaped damping member 51 made of elastic rubber has a multi-layer gourd shape larger than the diameter of the through hole of the hanging frame 2. When the hanging chain A21 breaks, the pulling rope 5 pulls the gourd-shaped damping member 51 to undergo elastic damping deformation and gradually get stuck in the through hole of the hanging frame 2 to play a damping and buffering protection role.

[0028] Hoisting: After the hook 3 is connected to the cable of the crane or tower crane, the two laminated plates 1 are hoisted. The two laminated plates 1 are ensured to be at the same horizontal state with a spacing through the laminated plate spacing assembly, realizing the synchronous lifting of the two laminated plates 1 from the placement point to the building installation point and then the synchronous lowering, which is beneficial to the synchronous assembly of the two laminated plates 1 and solves the problem that the two precast laminated plates in series cannot be lowered synchronously after being hoisted in place.
