Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a keel and plate installation structure. Background Technology

[0002] During the installation of some building materials, it is often necessary to set up keels for support and fixation to facilitate installation, overcome unevenness of the construction surface, and ensure a smooth paving effect.

[0003] However, when nailing the sheet metal to the metal keel, the high hardness of the metal keel requires applying a great deal of pressure to the screws to drive them into the keel, making the operation laborious. In addition, if the screws do not penetrate the keel in time, the rotating screws will cause the sheet metal on them to continue to move along the screw's axis, resulting in the sheet metal separating from the keel and causing the sheet metal to bulge, making it difficult to ensure that the sheet metal on the keel is laid flat. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a keel that facilitates the insertion of threaded connectors and reduces the effort required for connection.

[0005] The technical problem to be solved by this utility model is to provide a plate installation structure that allows the plate to be laid flat and labor-saving.

[0006] To solve the above-mentioned technical problems, this utility model provides a keel, including a body and a connecting part. The connecting part is provided with a connecting groove extending in the same direction as the body. The two groove walls opposite to the connecting groove are used to connect with a threaded connector that extends into the connecting groove.

[0007] As an improvement to the above solution, the connecting part is provided with a plurality of protruding teeth, which extend in the same direction as the body, and a connecting groove is formed between two adjacent protruding teeth.

[0008] As an improvement to the above solution, the threaded connector includes a column, a first thread, and a tapping end disposed at one end of the column. The tapping end is conical, and the first thread is spirally disposed on the tapping end and the column.

[0009] Wherein, the depth of the connecting groove is not greater than the axial length of the tapping end; and / or

[0010] The depth of the connecting groove is not less than the pitch of the first thread.

[0011] As an improvement to the above solution, the distance between the two adjacent groove walls on two adjacent protrusions is not greater than the diameter of the column; and / or

[0012] The distance between the two opposing groove walls on two adjacent protrusions is greater than the diameter of the column.

[0013] As an improvement to the above scheme, the distance between the two adjacent groove walls on two adjacent protrusions is no greater than 1 / 2 of the depth of the connecting groove.

[0014] As an improvement to the above solution, the connecting groove is designed to be open outwards at the opening.

[0015] As an improvement to the above solution, the body has a first cavity on the side opposite to the connecting portion; or

[0016] The main body has a receiving groove on the side away from the connecting part, and a support member is provided in the receiving groove. The support member abuts against the side of the main body away from the connecting part.

[0017] As an improvement to the above solution, the body is provided with support portions on opposite sides of the connecting portion, the support portions extending away from the connecting portion, and the support portions protruding or flush with the end of the tooth.

[0018] In addition, this utility model also provides a plate mounting structure, which includes a unit plate, a threaded connector and the aforementioned keel. The unit plates are arranged on the keel, and the threaded connector passes through the unit plate and is sequentially connected to the connecting part of the keel and the body.

[0022] Implementing this utility model has the following beneficial effects:

[0023] This utility model discloses a keel. By setting a connecting groove in the connecting part that extends in the same direction as the body, when the threaded connector is inserted into the connecting groove, the thread at the end of the threaded connector can generate friction with the groove wall, so that the threaded connector first connects with the groove wall. When the thread is screwed into the connecting part, it can promote the thread to screw further into the body, reduce the pressure required for the threaded connector to enter the keel body, facilitate the insertion of the threaded connector, and make the connection more efficient and labor-saving.

[0035] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 3As shown, the present invention discloses a first embodiment of a keel, including a body 1 and a connecting part 2. The connecting part 2 is provided with a connecting groove 21 extending in the same direction as the body 1. The two groove walls opposite to the connecting groove 21 are used to connect with a threaded connector a extending into the connecting groove 21.

[0037] In this embodiment, a connecting groove 21 extending in the same direction as the main body 1 is provided in the connecting part 2. When the threaded connector a is inserted into the connecting groove 21, the thread at the end of the threaded connector a can generate friction with the groove wall of the connecting groove 21, so that the threaded connector a connects with the groove wall first. When the thread is screwed into the connecting part 2, it can promote the thread to screw further into the main body 1, reduce the pressure required for the threaded connector a to enter the keel body 1, facilitate the entry of the threaded connector a, and make the connection more efficient and labor-saving.

[0038] Specifically, in this embodiment, the keel has a plurality of protruding teeth 22 arranged in an array at the connecting part 2. The protruding teeth 22 extend in the same direction as the body 1. Two adjacent protruding teeth 22 and the body 1 form the connecting groove 21. The threaded connector a is inserted into the body 1 of the keel through the connecting groove 21.

[0039] In this embodiment, the protruding teeth 22 of the connecting part 2 are formed on the body 1. The keel is preferably a metal profile that has been extruded or an extruded plastic strip. The body 1 of the keel and the protruding teeth 22 of the connecting part 2 can be integrally formed during the extrusion process. Of course, the keel can also be made of wood or other materials.

[0040] Along the connecting groove 21 formed by two adjacent protrusions 22, the threaded connector a can be driven into any position with minimal effort, allowing for flexible arrangement of the installation position of the threaded connector a. The connecting groove 21 structure is formed directly during the keel extrusion molding process. Compared with machining connecting holes one by one on the keel, the process is simpler, the structural strength is better, and the available connection positions for the threaded connector a are widely distributed, providing good installation adaptability. Machining connecting holes on the keel can easily lead to a mismatch between the machining position of the connecting hole and the target nailing position. If too many connecting holes are machined, it can easily weaken the strength of the keel.

[0041] In this embodiment, the keel structure can be configured in various ways outside of the connecting part 2. For example, such as... Figure 1 and Figure 4 , Figure 6 , Figure 7 , Figure 8 The keel body 1 can have a first cavity 3 on the side opposite to the connecting part 2, that is, the keel can be made of hollow profile; or, as Figure 9 and Figure 10The main body 1 of the keel is provided with a receiving groove 4 on the side away from the connecting part 2. That is, the keel can be made of an open profile. A support member b can be provided in the receiving groove 4. The support member b abuts against the side of the main body 1 away from the connecting part 2 to improve the stability of the keel support.

[0042] In addition, such as Figure 1 and Figure 4 , Figure 7 The keel body 1 can also be provided with support parts 5 on opposite sides of the connecting part 2. The support parts 5 extend away from the connecting part 2, and the provision of the support parts 5 increases the contact area of ​​the plate. The support parts 5 protrude or are flush with the end of the tooth 22, so that both the support parts 5 and the tooth 22 provide support for the plate, reducing the deformation of the plate during the screwing of the threaded connector a, and making it easier to screw the threaded connector a in.

[0043] like Figure 8 If necessary, connecting parts 2 can be provided on both sides of the main body 1. The connecting parts 2 are mirror-symmetrically arranged on both sides of the main body 1 to increase the direction in which the keel can be matched for installation.

[0044] For the threaded connector 'a' connected to the keel, a self-tapping screw is preferred, which includes a column a1, a first thread a2, and a tapping end a3 and a screw head a4 respectively located at both ends of the column a1. The screw head a4 is used to cooperate with a screwdriver or the like to rotate the threaded connector a. The tapping end a3 is conical, and the cross-sectional area of ​​the tapping end a3 gradually decreases from the end of the column a1. The first thread a2 is spirally arranged on the tapping end a3 and the column a1. The first thread a2 located at the end of the tapping end a3 is the tapping cutting edge of the threaded connector a.

[0045] To ensure that the threaded connector a can effectively tap the connecting part 2 of the keel, the structural dimensions of the threaded connector a need to be adapted to the connecting groove 21. Specifically, in this embodiment, the groove depth of the connecting groove 21 is not greater than the axial length of the tapping end a3, so as to avoid interference between the first thread a2 located on the column a1 part and the protruding tooth 22 before the tapping end a3 cuts into the protruding tooth 22.

[0046] More preferably, the groove depth of the connecting groove 21 is not less than the pitch of the first thread a2, so that the connecting groove 21 provides sufficient screwing space to ensure that the tapping end a3 can effectively cut into the protruding tooth 22 in the connecting groove 21, providing sufficient biting force for further tapping into the main body of the keel.

[0047] In addition, the distance between the two adjacent groove walls on the two protrusions 22, that is, the distance between the two opposite groove walls of the connecting groove 21, is not greater than the diameter of the column a1, so as to ensure that the first thread a2 can be completely cut into the protrusion 22.

[0048] More preferably, the distance between the two adjacent groove walls on the two protrusions 22 that are close to each other, that is, the distance between the two opposite groove walls of the connecting groove 21, is preferably no greater than 1 / 2 of the groove depth of the connecting groove 21, so that the connecting groove 21 provides sufficient screwing space while increasing the biting force between the connecting part 2 and the threaded connector a.

[0049] The distance between the two opposing groove walls on two adjacent protrusions 22 is greater than the diameter of the column a1, so as to avoid excessive resistance between the first thread a2 located in the column a1 and the protrusion 22 when the tapping end a3 taps into the main body, and to achieve more effortless operation during the screwing process of the entire threaded connector a.

[0050] like Figure 3 As shown, in this embodiment, the two opposite walls of the connecting groove 21 can be configured to be perpendicular to the bottom of the connecting groove 21; as Figure 5 As shown, the two opposite walls of the connecting groove 21 can also be made at an obtuse angle to the bottom of the connecting groove 21, so that the threaded connector a can be inserted into the connecting groove 21.

[0051] In this embodiment, the connecting groove 21 is preferably open at the opening, that is, the protruding tooth 22 is provided with an inclined surface at the opening of the connecting groove 21, so that the tapping end a3 of the threaded connector a can extend into the connecting groove 21 without obstruction, or even directly abut against the body 1 of the keel.

[0052] This utility model also provides a plate mounting structure, which includes a unit plate, a threaded connector a and the aforementioned keel. The unit plates are arranged on the keel, and the threaded connector a passes through the unit plate and is sequentially connected to the connecting part 2 and the body 1 of the keel.

[0053] When the panel installation structure of this embodiment is applied to the panel laying process, the threaded connector a passing through the unit panel can easily continue to drive into the keel, which saves effort and avoids the unit panel and keel gradually moving away from each other as the threaded connector a rotates, resulting in the unit panel bulging.

[0054] Preferably, the threaded connector a includes a column a1, a first thread a2, and a tapping end a3 at one end of the column a1, the tapping end a3 being conical, and the first thread a2 being spirally arranged on the tapping end a3 and the column a1; the threaded connector a has a second thread a5 on the column a1, the second thread a5 having the same spiral direction as the first thread a2, and a preset distance between the second thread a5 and the first thread a2, the preset distance preferably being the thickness of the unit plate; the keel is connected to the first thread a2, the unit plate passes through the first thread a2, and is connected to the second thread a5.

[0055] By setting a first thread a2 and a second thread a5 with a preset distance on the threaded connector a, the axial displacement of the unit board relative to the column a1 during the process of the threaded connector a being driven into the keel is further avoided, that is, the phenomenon of the board bulging. This allows the unit board to always be attached to the keel for nailing, which helps to improve the flatness of the board laying.

[0056] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
