Description

Technical Field

[0001] The utility model belongs to the technical field of composite beams, in particular to a composite continuous beam. Background Art

[0002] A composite continuous beam is a structural design widely used in bridge engineering and construction. This beam consists of several spans and is continuous at the fulcrum, unlike a simply supported beam, without the articulation that is characteristic of a simply supported beam. A composite continuous beam can be made of different materials, such as reinforced concrete, steel, or a combination of them, to take advantage of the advantages of both materials, and can be made into prefabricated components to improve construction efficiency and quality control.

[0003] For example, a new type of assembled I-beam-wood composite beam is disclosed in the Chinese utility model patent with announcement number CN218757972U. The device connects the I-beam and the wood floor slab through bolts coated with structural adhesive, so that the steel beam and the wood floor slab are subjected to joint force, thereby improving the durability of the connection between the steel beam and the wood floor slab.

[0004] In actual use of the device, since the bolts need to be tightened sequentially during assembly, it is not only troublesome but also reduces the assembly efficiency of the composite beam, thereby making it inconvenient to quickly install the composite beam.

[0005] In summary, there is a need for a composite continuous beam that can be quickly installed. Utility Model Content

[0006] The utility model aims to provide a combined continuous beam. During the installation of the continuous beam, the card block can be driven to be inserted into the card slot, thereby realizing the rapid assembly of the combined beam and effectively improving the assembly efficiency of the combined beam.

[0007] The technical solution adopted by the utility model to solve the above problems is: a combined continuous beam, comprising:

[0008] Concrete slabs;

[0009] An I-beam, wherein the I-beam is arranged on the lower surface of the concrete slab;

[0010] A quick assembly component, the quick assembly component comprises a first bidirectional screw rotatably connected to the I-beam, both sides of the first bidirectional screw are externally threadedly connected to a moving plate, and one end of the first bidirectional screw is coaxially fixedly connected to a rotating handle;

[0011] A second bidirectional screw, wherein the second bidirectional screw is horizontally rotatably connected to the top of the moving plate, both sides of the second bidirectional screw are threadedly connected to moving blocks, and one end of the second bidirectional screw is coaxially fixedly connected to a hand wheel;

[0012] A connecting plate is horizontally arranged above the moving plate, a connecting rod is hinged between the bottom of the connecting plate and the moving block through a hinge, and a clamping block is fixedly installed on the top of the connecting plate.

[0013] A further preferred technical solution is that a first guide rod is fixedly connected to the side of the first bidirectional screw, and the first guide rod is slidably connected to the movable plate.

[0014] The role of the guide rod in the mechanical system is to ensure that the moving component moves accurately and stably along the predetermined axis and prevent the moving plate from deflecting or swinging in other directions. And for a driving component such as a screw that may cause rotation, the guide rod can prevent the moving part connected to the screw from rotating with the screw.

[0015] A further preferred technical solution is that a second guide rod is fixedly installed below the second bidirectional screw, and the second guide rod is slidably connected to the moving block.

[0016] A further preferred technical solution is that the card block is fixedly connected to the top of the connecting plate, and the top of the card block extends laterally.

[0017] The card block is a part with a specific geometric shape, which is fixedly connected to the top of the connecting plate. Specifically, the top of the card block extends along a side of the connecting plate, and this extension forms a surface perpendicular to the horizontal plane, so that the overall shape of the card block is an inverted L shape. This inverted L shape indicates that the card block has two main right-angled surfaces: one is a vertical surface fixed to the connecting plate, and the other is a horizontal surface extending laterally from the top of the connecting plate.

[0018] A further preferred technical solution is that a first horizontal movement slot penetrating the I-beam is symmetrically provided on the top of the I-beam, and a second horizontal movement slot is symmetrically provided on the bottom of the concrete slab.

[0019] A further preferred technical solution is that: the bottom of the concrete slab is symmetrically provided with slots which are connected to the second horizontally movable slot.

[0020] A further preferred technical solution is that the first horizontal movement slot and the second horizontal movement slot are located on the same vertical line and are interconnected.

[0021] A further preferred technical solution is that the first horizontal movement slot and the second horizontal movement slot are used to install the top end of the block.

[0022] A further preferred technical solution is that the vertical width of the card slot is greater than the vertical width of the top of the card block.

[0023] The vertical width of the card slot is greater than the vertical width of the top of the card block, which indicates that the card slot is designed with enough clearance to accommodate the insertion and removal of the card block. Such a structural feature allows the card slot to easily install or remove the card block while maintaining the position stability of the card block after installation.

[0024] A further preferred technical solution is that an anti-slip sleeve is provided on the outside of the turning handle and the hand wheel.

[0025] Among them, the anti-slip sleeve is usually made of a material that can provide additional friction so that the operator can obtain a better grip and control when using the handle or hand wheel, such as rubber, silicone, etc.

[0026] In summary, the utility model has the following benefits:

[0027] The utility model drives the second bidirectional screw to rotate by rotating the hand wheel, and the rotation of the second bidirectional screw drives the two groups of moving blocks threadedly connected thereto to move toward each other, and utilizes the hinge effect of the moving block and the connecting plate and the connecting rod to push the card block to rise and insert it into the horizontal moving groove, and drives the first bidirectional screw to rotate by rotating the handle, so that the two groups of moving plates threadedly connected thereto can be driven to move toward each other, thereby driving the two groups of card blocks on the same side to be inserted into the card slots at the same time, thereby realizing the rapid assembly of the composite beam and effectively improving the assembly efficiency of the composite beam.
