Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a deformation expansion joint structure of a building. Background Art

[0002] Building deformation expansion joints, commonly known as expansion joints or temperature joints, are structural joints set in buildings to compensate for the displacement and deformation of buildings caused by temperature changes, earthquakes, uneven foundation settlement, etc. The setting of expansion joints can prevent excessive structural stress caused by these factors, thereby avoiding cracks or other damage to the building and ensuring the safety and durability of the building.

[0003] However, the above device still has the following problems during implementation:

[0004] The existing technology makes it possible to seal the deformation expansion joints of buildings with polyurethane sealants. When the polyurethane sealants dry out and crack, moisture will penetrate into the building through the expansion joints, accelerating the carbonization process of the concrete and reducing the durability and bearing capacity of the concrete. Therefore, a building deformation expansion joint structure is proposed to solve the above problems. Utility Model Content

[0005] In response to the problems existing in the prior art, the utility model provides a building deformation expansion joint structure with the advantages of multi-layer sealing, which can overcome the above problems or at least partially solve the problem that when the polyurethane sealant dries and cracks, moisture will penetrate into the interior of the building through the expansion joint, which will accelerate the carbonization process of the concrete and reduce the durability and bearing capacity of the concrete.

[0006] The utility model is implemented as follows: a building deformation expansion joint structure includes two walls, two matching grooves, two metal bonding plates and a metal baffle. The matching grooves are opened on the opposite sides of the two walls, the metal bonding plates are plugged into the inner cavity of the matching grooves, the metal baffles are movably connected to the tops of the metal bonding plates, and the metal bonding plates can be connected to the walls by expansion screws.

[0007] As a preferred embodiment of the present invention, the two metal bonding plates are fixedly connected to each other on one side, and there are multiple springs. The side of the spring close to the metal baffle is fixedly connected to the metal baffle. By setting the spring, when the metal bonding plate is driven by the wall and approaches the metal baffle, the spring can connect the metal bonding plate and the metal baffle, so that the metal baffle will not detach from the metal bonding plate.

[0008] As a preferred embodiment of the present invention, a first T-shaped groove is provided on the top of the metal plywood, and a second T-shaped groove is provided on the left and right sides of the top of the metal baffle. The inner cavities of the first T-shaped groove and the second T-shaped groove are movably connected with a retractable seal. By setting the first T-shaped groove, the second T-shaped groove and the retractable seal, the first T-shaped groove and the second T-shaped groove can position the retractable seal, and the retractable seal can intercept rainwater.

[0009] As a preferred embodiment of the present invention, docking grooves are provided on the left and right sides of the bottom of the metal plywood, and the inner cavity of the docking groove is plugged and connected with a sealing belt, and the number of the sealing belts is two. By setting the docking grooves and the sealing belts, when the retractable seal is used for a long time and cracks appear, rainwater enters the connection, and at this time the sealing belt can also prevent rainwater from entering between the two walls.

[0010] As a preferred embodiment of the present invention, travel grooves are provided on the front and rear sides of the inner cavity of the metal plywood, and the inner cavity of the travel groove is slidably connected with a travel plate. By setting the travel groove and the travel plate, the moving position of the metal plywood can be controlled when the travel plate moves in the travel groove, and the L-shaped travel rod will not separate from the travel groove.

[0011] As a preferred embodiment of the present invention, both sides of the front and rear sides of the bottom of the metal baffle are fixedly connected with L-shaped stroke rods, and the side of the L-shaped stroke rod close to the stroke groove passes through the metal baffle and is fixedly connected to the stroke plate. By setting the L-shaped stroke rod, the L-shaped stroke rod can prevent the metal baffle from moving up and down when the metal bonding plate moves at the bottom of the metal baffle, thereby increasing stability during movement.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model provides a metal plywood, a metal baffle, a retractable seal and a sealing tape for use in combination. The retractable seal can prevent rainwater from entering the connection between the metal plywood and the metal baffle. If the retractable seal develops cracks due to long-term use, rainwater enters the connection. At this time, the sealing tape can also prevent rainwater from entering between the two walls, thereby solving the problem that when the polyurethane sealant dries and cracks, moisture will penetrate into the interior of the building through the expansion joint, which will accelerate the carbonization process of the concrete and reduce the durability and bearing capacity of the concrete.

[0032] When in use, pick up two metal plywood plates 3 and connect them with the matching grooves 2 on the wall 1, and then fix the metal plywood plates 3 with expansion screws. When the building deforms due to thermal expansion and contraction, the two walls 1 move closer to each other, which will drive the two metal plywood plates 3 to move closer to each other, squeezing the spring 5 and approaching the metal baffle 4.
