Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a two-way close-joined prefabricated composite board. Background Art

[0002] Precast concrete composite slabs, also known as composite floor slabs, are assembled integral floor slabs composed of precast slabs and cast-in-place concrete layers. When in use, the precast composite slabs are transported to the work site, and then the cast-in-place concrete layer is poured on the top surface of the precast composite slabs on site. The composite floor slabs have good integrity, and the upper and lower surfaces of the slabs are flat, which is convenient for the decoration of the finishing layer. They are suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity. Since composite slabs are often used in indoor buildings, the connection between two adjacent composite slabs should have a certain tensile resistance.

[0003] The two-way close-jointed prefabricated composite panels in the current prior art are prone to cracks at the joints, which affects the use of the prefabricated concrete composite panel floor. In addition, most of the existing prefabricated composite panels are one-piece, and the one-piece structure causes the prefabricated composite panels to be heavy, inconvenient to construct and install, and cannot meet current usage needs. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that cracks are easily formed at the joints in the prior art, which affects the use of precast concrete composite slabs, and most of the existing precast concrete composite slabs are of an integrated type. The integrated structure causes the precast concrete composite slabs to be heavy, inconvenient to construct and install, and cannot meet the current use needs. A two-way close-jointed precast concrete composite slab is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a two-way close-joined prefabricated composite plate, including a first lower plate body, a second lower plate body is provided on one side of the first lower plate body, a first clamping block is fixed to one end of the second lower plate body facing the first lower plate body, a first clamping groove matching the first clamping block is provided at one end of the first lower plate body facing the second lower plate body, a first upper plate body is provided above the first lower plate body, a second upper plate body is provided on one side of the first upper plate body, a first limit block is fixed to one side of the bottom end of the first upper plate body and the second upper plate body, a first limit groove matching the first limit block is provided at the top of the first lower plate body and the second lower plate body, and an opening is provided at one side of the top of the first lower plate body and the second lower plate body located at the first limit groove.

[0006] Preferably, a second limiting block is fixed to the other side of the bottom end of each of the first upper plate body and the second upper plate body, and a second limiting groove matching the second limiting block is formed at one end of each of the first lower plate body and the second lower plate body.

[0007] Preferably, guide blocks are fixed to the top ends of the first lower plate body and the second lower plate body, and guide grooves matching the guide blocks are formed at the bottom ends of the first upper plate body and the second upper plate body.

[0008] Preferably, a second slot is formed at one end of the second lower plate body away from the first lower plate body, and one end of the first slot and the second slot are both sealed.

[0009] Preferably, trusses are fixed to the top ends of the first upper plate body and the second upper plate body.

[0010] Preferably, opposite ends of the first upper plate body and the second upper plate body abut against each other, and the second upper plate body is arranged above the first lower plate body and the second lower plate body.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] In the utility model, by setting the first upper plate body and the second upper plate body, the first upper plate body and the second upper plate body can stably block the connection gap between the first lower plate body and the second lower plate body, so as to prevent rainwater from falling from the gap between the first lower plate body and the second lower plate body when the composite plate is in use, and the practicality is stronger. In addition, by setting the first clamping block and the first clamping groove, the first lower plate body and the second lower plate body are slidably assembled and connected by the first clamping block and the first clamping groove, and the first clamping block and the first clamping groove can also separate the gap, and the sealing is stronger. In addition, the device is provided by the first clamping block and the first clamping groove. A limit block and a second limit block are set. When the first lower plate body and the second lower plate body are slidably spliced, the first upper plate body and the second upper plate body are guided by the guide block to move the two first limit blocks to the opening. At this time, the first upper plate body and the second upper plate body are pressed down to make the two first limit blocks enter the opening, and then the first upper plate body and the second upper plate body are slid again to make the first limit block move into the first limit groove. At the same time, the second limit block will also move into the second limit groove, so that the first upper plate body and the second upper plate body are connected with the first lower plate body and the second lower plate body.
