Prefabricated laminated slab splicing structure

Abstract

This utility model discloses a prefabricated composite slab splicing structure, relating to the technical field of composite slabs. It solves the problem that in the current method of using composite slabs, the connection is achieved by sliding between positioning steel bars and positioning holes, followed by securing adjacent connecting steel bars with stirrups. However, the sliding connection between positioning holes and positioning rods is inherently not secure, and the installation of stirrups can easily increase the gaps between adjacent composite slabs, making the stirrup securing work more difficult. The new structure includes a composite slab, an L-shaped connecting plate, and an L-shaped connecting groove. The L-shaped connecting plate is symmetrically and securely connected to the left sidewall of the composite slab. The connection between the L-shaped connecting plate and the L-shaped connecting groove allows for initial positional securing of adjacent composite slabs during the initial connection process, resulting in a more stable connection between the composite slabs during subsequent securing work.

Description

Technical Field

[0001] This utility model relates to the technical field of composite panels, specifically to an assembled composite panel splicing structure. Background Technology

[0002] Composite floor slabs are assembled monolithic floor slabs composed of precast slabs and cast-in-place reinforced concrete layers. A search revealed Chinese patent CN 213572573U, which discloses a composite concrete slab splicing structure, including a first composite slab, a first connecting steel bar, a second composite slab, and a sleeve column. The first connecting steel bar is fixedly installed on the top surface of one end of the first composite slab. A first positioning hole is formed on one side of the first composite slab, and a second positioning steel bar is inserted into the first positioning hole. The second positioning steel bar is fixedly installed on one side of the second composite slab. A second connecting steel bar is fixedly installed on the top surface of one end of the second composite slab. A second positioning hole is formed on one side of the second composite slab, and a first positioning steel bar is inserted into the second positioning hole. The first positioning steel bar is fixedly installed on one side of the first composite slab. This utility model uses staggered positioning steel bars inserted into positioning holes to connect two composite slabs, improving shear stress. Furthermore, the connecting steel bars fixed at the top by stirrups have movable sleeve columns, allowing the pointed ends to help drive the stirrups to the bottom column when they are driven in. However, when using this composite slab, it is slidably connected to the positioning bars and positioning holes, and then the adjacent connecting bars are tightened by stirrups to make the connected composite slabs secure. However, the connection between the positioning bars and positioning holes is not secure enough. When installing the stirrups, the gaps between adjacent composite slabs are easily enlarged, making the stirrup tightening work more difficult. At the same time, the stirrups need to be tightened with wire, and after the composite slabs are connected to each other, there are multiple connecting bars inside, which requires multiple stirrups to be installed, increasing the labor force of workers and reducing the efficiency of the equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a prefabricated composite slab splicing structure. This solves the problem that when composite slabs are used, they are connected by sliding connections between positioning steel bars and positioning holes, and then secured with stirrups to adjacent connecting steel bars. While this allows for a secure connection between the composite slabs, the sliding connection between the positioning holes and positioning rods itself cannot be securely fastened. Furthermore, the installation of stirrups can easily increase the gaps between adjacent composite slabs, making the stirrup fastening work more difficult. Since stirrups need to be secured with wire, and the composite slabs have multiple connecting steel bars inside after interconnection, multiple stirrups are required for installation, increasing the labor required and reducing the efficiency of the device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated composite panel splicing structure, comprising a composite panel, an L-shaped connecting plate, and an L-shaped connecting groove. The L-shaped connecting plate is symmetrically and fastened to the left side wall of the composite panel. The L-shaped connecting groove is symmetrically arranged inside the top surface of the right end of the composite panel. The L-shaped connecting plate is slidably connected to the inside of the L-shaped connecting groove of an adjacent composite panel through the composite panel. After installation, the top surface of the L-shaped connecting plate is horizontal to the top surface of the composite panel.

[0005] Preferably, the composite plate is symmetrically provided with connecting steel bars inside, and the connecting steel bars are all fixedly installed inside the L-shaped connecting groove. The top surface of the L-shaped connecting plate is provided with a second connecting groove, and the L-shaped connecting plate is slidably sleeved on the bar wall of the connecting steel bar, thereby strengthening the positional stability of the L-shaped connecting plate after connection.

[0006] Preferably, the composite plate is internally connected with a cross steel plate. A cross groove is provided inside the top surface of the right end of the composite plate, and a first connecting groove is provided inside the top surface of the left end of the composite plate. The first connecting groove is connected to the interior of the cross groove. Both ends of the cross groove are connected to the interior of the second connecting groove. The cross steel plate is slidably connected inside the cross groove, and the right end and the front and rear ends of the cross steel plate are respectively connected to the interior of the first connecting groove and the second connecting groove. The cross steel plate is symmetrically threaded with fixing bolts inside, and the bottom of each fixing bolt is threaded to the interior of the top surface of the cross groove. The front and rear ends of the cross steel plate are slidably sleeved on the wall of the connecting steel bar, thereby conveniently reinforcing the position of the L-shaped connecting plate and strengthening the tightness of the connection between the composite plates.

[0007] Preferably, threaded holes are symmetrically arranged inside the left sidewall of the composite plate, and fastening bolts are fixedly connected to the right sidewall of the L-shaped connecting plate. The fastening bolts are threaded into the threaded holes through the L-shaped connecting plate, thereby facilitating the disassembly of the L-shaped connecting plate on the composite plate where no connecting parts are needed.

[0008] This utility model provides a prefabricated composite panel splicing structure. It has the following beneficial effects:

[0009] 1. This prefabricated composite panel splicing structure, when using the prefabricated composite panel splicing structure, through the connection between the set L-shaped connecting plate and L-shaped connecting groove, enables the adjacent composite panels to be fastened in the first step when they are connected, so that the connection between the composite panels can be more stable when subsequent fastening connection work is carried out.

[0010] 2. This prefabricated composite panel splicing structure, when used, through the cooperation between the set cross steel plate and cross groove, the first connection and the second connection groove, can make the position of the L-shaped connecting plate more stable when fastening adjacent composite panels, and at the same time make the fastening work between composite panels more convenient.
