Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building curtain wall construction technology, and specifically refers to a foam rod filling depth measuring instrument. Background Technology
[0002] After the panels of framed metal and stone building curtain walls are installed on site, sealant needs to be applied to the seams between the panels. The current traditional method is to insert a foam stick into the sealant seams of the metal or stone curtain wall by hand or with a flathead screwdriver, and then apply the sealant. This method results in uneven filling depth of the foam stick, wasting sealant in some areas and leaving too thin a sealant layer in others, which may lead to water leakage. Utility Model Content
[0003] The purpose of this invention is to provide a foam rod filling depth control device that can ensure that the foam rod filling depth is consistent and meets the specifications, thereby eliminating the risk of leakage after applying sealant.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A foam rod filling depth measuring instrument includes a filling pressure roller assembly, a self-removing embedded bearing, and an assembled handle. The filling pressure roller assembly includes filling pressure rollers of various specifications. Each filling pressure roller includes a cylindrical body with a circular protrusion coaxially arranged in the middle of the outer ring of the cylindrical body. Circular protrusions of different heights are set to form filling pressure rollers of various specifications. Convex countersunk holes are opened at both ends of the filling pressure roller along the axis. The large-diameter outer hole of the convex countersunk hole holds the self-removing embedded bearing, which is a cylindrical ring that matches the large-diameter outer hole. The assembled handle is made of round steel bent into a slingshot shape with a [] shaped top and two locking protrusions at its free end for locking into the center hole of the self-removing embedded bearing.
[0005] Furthermore, the cylindrical body has a diameter of 30mm and a height of 40mm; the outer diameter of the convex countersunk hole has a diameter of 12mm and a height of 4mm; and the inner diameter of the small hole has a diameter of 4mm and a height of 6mm.
[0006] Furthermore, the circular protrusion has a diameter of 44mm and six different heights of 10mm, 13mm, 18mm, 4mm, 6mm, and 8mm.
[0007] Furthermore, the self-removing insert bearing has a diameter of 12mm, a height of 3mm, and a central hole with a diameter of 4mm, which is used to fix a 4mm diameter, 20mm long clip on the top of the assembled handle.
[0008] Furthermore, the assembled handle is made of round steel with a diameter of 4mm bent, with a cross-section height of 168mm, a handle length of 130mm, a top width of 64mm, a top height of 38mm, a locking protrusion spacing of 24mm, and a locking protrusion length of 20mm.
[0009] Furthermore, the filling roller can be made of resin or plastic.
[0010] Furthermore, the material of the disassembled embedded bearing is steel.
[0011] The beneficial effects of this utility model are: it is easy to assemble and disassemble, simple to operate, applicable to construction of various joint widths and fixed depths, improves construction efficiency and quality, eliminates glue waste, can be reused, and is green and environmentally friendly.

[0021] Please see Figures 1 to 9The invention relates to a foam rod filling depth measuring instrument, comprising a filling pressure roller assembly 1, a self-removing embedded bearing 2, and an assembled handle 3. The filling pressure roller assembly includes filling pressure rollers of various specifications. Each filling pressure roller includes a cylindrical body 11, with a circular protrusion 12 coaxially arranged in the middle of the outer ring of the cylindrical body. Circular protrusions of different heights are set to form filling pressure rollers of various specifications. Convex countersunk holes 13 are opened at both ends of the filling pressure roller along the axis. The large-diameter outer hole of the convex countersunk hole houses the self-removing embedded bearing 2, which is a cylindrical ring that matches the large-diameter outer hole. The assembled handle is made of round steel bent into a slingshot shape with a [] shape at the top and a locking protrusion at its free end. The two locking protrusions are used to lock into the center hole of the self-removing embedded bearing.
[0022] Specifically, the cylindrical body has a diameter of 30mm and a height of 40mm; the outer diameter of the convex countersunk hole has a diameter of 12mm and a height of 4mm; the inner diameter of the smaller hole has a diameter of 4mm and a height of 6mm. The circular convex post has a diameter of 44mm and comes in six specifications with heights of 10mm, 13mm, 18mm, 4mm, 6mm, and 8mm, respectively. Figure 7 As shown.
[0023] like Figure 8 As shown, the self-removing insert bearing has a diameter of 12mm and a height of 3mm, with a central hole diameter of 4mm for securing a 4mm diameter, 20mm long retaining protrusion at the top of the assembly handle. The self-removing insert bearing is made of steel.
[0024] like Figure 9 As shown, the assembled handle is made of 4mm diameter round steel bent into shape, with a cross-section height of 168mm, a handle length of 130mm, a top width of 64mm, a top height of 38mm, a locking protrusion spacing of 24mm, and a locking protrusion length of 20mm. The filling pressure roller can be made of resin or plastic.
[0025] The assembly method of this utility model is as follows: Take two self-removing insert bearings and embed them into the large-diameter outer holes of the convex countersunk holes on both sides of the filling roller. Then, insert the locking protrusion of the assembly handle into the self-removing insert bearings on both sides of the filling roller, completing the assembly. When a different depth is required, remove the assembly handle and assemble it again with the required filling roller and self-removing insert bearings. The process is scientific and reasonable, easy to operate, and highly practical. This utility model can realize assembly installation and removal, is convenient to operate, highly versatile, and saves materials and is environmentally friendly. In practical applications, it has superior performance, convenient construction, high efficiency, and strong versatility.
