Abstract
Description
Technical Field
[0001] This utility model relates to the field of building decoration technology, and in particular to a connection structure for prefabricated ceiling keel. Background Technology
[0002] Prefabricated ceilings are widely used in existing building interior decoration due to their quick construction and environmental friendliness. Their core structure typically consists of main keels, secondary keels, and hanging components connecting them. Traditionally, keel connections are mostly achieved using hooks or screws for fixing.
[0003] Connecting the crossarm and keel requires bolts for fixing. Precise alignment of the bolt holes on the crossarm and keel is crucial, especially when the structure is unstable or when operating alone, making it extremely laborious. The process involves inserting the bolt, putting on the washer, tightening the nut, pre-tightening with tools, and finally securing it. Each step is time-consuming, necessitating the use of appropriate wrenches, sockets, and other tools. Power tools may be limited by power supply or weight constraints. Utility Model Content
[0004] Purpose of the Invention: The purpose of this utility model is to provide a connecting structure for prefabricated ceiling joists. Connecting the horizontal arm and the joist requires bolts for fixing, necessitating precise alignment of the bolt holes on the horizontal arm and the joist. This is particularly laborious when the structure is unstable or when operating alone. The process involves inserting the bolt, putting on the washer, tightening the nut, pre-tightening with tools, and finally securing it. Each step is time-consuming, requiring the use of appropriate wrenches, sockets, and other tools. Furthermore, power tools may be limited by power supply or weight constraints.
[0005] Technical solution: Includes a fixing plate, with a fixing rod fixedly installed at the bottom of the fixing plate, and a main keel fixedly installed at the bottom of the fixing rod. Multiple connectors are fixedly installed on the outside of the main keel, including a clamping plate and a flexible top plate. Two clamping slots are fixedly installed on the inside of the main keel, and a secondary keel is installed inside the clamping slots. The main keel and the secondary keel are made of flexible steel. The connectors are fixedly installed on the outside of the main keel by riveting, and the clamping slots are fixedly installed on the lower inside of the main keel by riveting.
[0006] By adopting the above technical solution, multiple connectors are provided. The upper part of the connector is equipped with a clamping plate, which can use its own elasticity to press the outer end of the cross arm. The lower part is equipped with an elastic top plate, which can support the cross arm. This eliminates the need for bolts, reduces operation time, and reduces the use of tools, thus greatly improving work efficiency.
[0007] Optionally, the fixing plate has fixing holes at both ends, which are formed by stamping, and the fixing plate is made of stainless steel.
[0008] By adopting the above technical solution, bolts are installed in the fixing holes to fix the plate to the ceiling.
[0009] Optionally, an elastic pad made of rubber is installed on the top of the fixing plate.
[0010] By adopting the above technical solution, the elastic pad is installed between the fixed plate and the ceiling to support the two. The elastic support makes the two tightly connected, and at the same time has a damping effect, reducing vibration and preventing loosening.
[0011] Optionally, the main keel is fixedly installed at the bottom of the fixing rod by nuts one and two. The outer circumference of the fixing rod is provided with two external threads that are alternately forward and reversed, with a thread pitch of 2 mm. The threads of nuts one and two are turned in opposite directions.
[0012] By adopting the above technical solution, nut one and nut two can form an interlock by using opposite thread directions to lock the main keel.
[0013] Optionally, multiple adjustment holes are provided in the middle part of the top of the main keel, and the adjustment holes are made by stamping.
[0014] By adopting the above technical solution, the adjustment hole is used to fix the rod in, which facilitates the adjustment of the front and rear positions.
[0015] Optionally, the slot includes an upper stop bar and a lower support bar, with a groove between the upper stop bar and the lower support bar, which are manufactured by thermoforming.
[0016] By adopting the above technical solution, the upper stop strip and the lower support strip are used to form a groove for fixing the secondary keel.
[0017] Optionally, the secondary keel includes a main body, with a retaining strip at the upper part of the outer end of the main body. The retaining strip is made by casting, and the secondary keel is made of aluminum alloy.
[0018] By adopting the above technical solution, the clip is used to snap into the groove for fixing the secondary keel.
[0019] Optionally, a baffle is provided at the lower part of the outer end of the body, and the baffle is made by casting.
[0020] By adopting the above technical solution, the baffle is used to cover the bottom of the main keel, resulting in a better appearance.
[0021] Beneficial effects: This utility model is equipped with multiple connectors. The upper part of the connector is equipped with a clamping plate, which can use its own elasticity to press the outer end of the cross arm. The lower part is equipped with an elastic top plate, which can support the cross arm. This eliminates the need for bolts, reduces operation time, and reduces the use of tools, thus greatly improving work efficiency. Attached Figure Description

[0023] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, such as... Figures 1 to 6 The invention includes a fixed plate 1, a fixed rod 3 fixedly installed at the bottom of the fixed plate 1, a main keel 4 fixedly installed at the bottom of the fixed rod 3, and multiple connectors 5 fixedly installed on the outside of the main keel 4. Each connector 5 includes a clamping plate 52 and an elastic top plate 51. Two slots 11 are fixedly installed on the inside of the main keel 4, and a secondary keel 6 is installed on the inside of the slots 11. The invention is provided with multiple connectors 5. The upper part of the connector 5 is provided with a clamping plate 51, which can use its own elasticity to press the outer end of the cross arm. The lower part is provided with an elastic top plate 52, which can support the cross arm, avoiding the use of bolts, reducing operation time, reducing tool use, and greatly improving work efficiency.
