Technical Field
[0001] The utility model belongs to the technical field of building material application, and particularly relates to a double-clad door frame capable of grouting. Background Art
[0002] Door covers refer to the two door frames inside and outside the door. Its main function is to fix the door leaf and protect the corners and decorations. It is often used in the decoration process to protect the door from scratches, corrosion, damage, dirt, etc. In the installation of the door cover of the existing medical steel door, the main door cover is first fixed to the door opening by screws, and then foam glue is applied between the door cover and the door opening to fill the gap between the main door cover and the door opening. Then, the secondary door cover is inserted to complete the installation of the entire door cover.
[0003] Although the use of foam glue can fill the gaps in door frames, due to the foaming characteristics of foam glue, it is difficult to completely fill the gaps in door frames, and there are a lot of hollow places. Although the use of mortar can effectively solve the problem of hollows, if mortar is used for filling, after the mortar dries, the secondary door frame will be difficult to insert into the main door frame, which will make it unusable. Therefore, how to use mortar for filling and ensure the installation of the secondary door frame is a problem that needs to be solved at present. Utility Model Content
[0004] The utility model aims at the technical problem existing in filling the gap of door frame with mortar, and proposes a double-clad door frame which is groutable and has reasonable design, simple structure, convenient processing and can effectively meet the needs of filling mortar.
[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: the utility model provides a double-clad door frame that can be grouted, including a main door frame and a secondary door frame made of metal, the main door frame is provided with a U-shaped bend at one end close to the secondary door frame, and the main door frame is also provided with a connecting sleeve at one end close to the secondary door frame, the connecting sleeve is U-shaped, the opening direction of the connecting sleeve is opposite to the opening direction of the U-shaped bend, the connecting sleeve and the U-shaped bend are arranged crosswise with each other, and a gap for inserting the secondary door frame is formed between the side of the connecting sleeve away from the main door frame and the U-shaped bend.
[0006] Preferably, the end of the connecting sleeve on the side close to the auxiliary door sleeve is bent toward the side away from the gap.
[0007] Preferably, the side of the connecting sleeve close to the main door sleeve is bonded to the main door sleeve.
[0008] Preferably, a bonding protrusion is provided on the side wall of the connecting sleeve on the side close to the main door sleeve.
[0009] Compared with the prior art, the advantages and positive effects of the utility model are:
[0010] 1. The utility model provides a double-wrapped door frame that can be grouted. By using the setting of a connecting sleeve, the outer side surface of one side is directly bonded to the mortar, thereby including the gap formed by the inner side surface and the U-shaped bend. At the same time, by using the setting of the U-shaped bend, it has a certain elasticity in the case of metal material, thereby facilitating the insertion of the auxiliary door frame, thereby solving the problem that the double-wrapped sleeve cannot be used when using mortar.

[0014] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0015] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0016] Embodiment 1, as Figure 1 As shown, this embodiment aims to solve the problem that the door frame of the medical steel door cannot use mortar to fill the gap 4 to avoid hollowing. Considering that the biggest problem with the use of mortar is the subsequent insertion of the secondary door frame 2, since the mortar and the main door frame 1 are bonded together, the possibility of inserting the secondary door frame 2 is blocked. Therefore, in order to solve the bonding problem, the groutable double-clad door frame provided in this embodiment includes a main door frame 1 and a secondary door frame 2 made of metal. In this embodiment, the metal materials are all stainless steel plates. Of course, other metal materials such as copper plates can also be considered.
[0017] In order to achieve the insertion of the secondary door frame 2, in the present embodiment, a U-shaped bend 11 is provided at one end of the main door frame 1 close to the secondary door frame 2. The U-shaped bend 11 is provided for two purposes. One is to facilitate the cross setting of the connecting sleeve 3, and the other purpose is to utilize the elasticity of the U-shaped bend 11 to facilitate the insertion of the secondary door frame 2.
[0018] In order to avoid adhesion between the main door cover 1 and the mortar at the position where the secondary door cover 2 is inserted, in this embodiment, a connecting sleeve 3 is further provided at one end of the main door cover 1 close to the secondary door cover 2, and the connecting sleeve 3 is also arranged in a U-shape, and the opening direction of the connecting sleeve 3 is arranged opposite to the opening direction of the U-shaped bend 11, and the connecting sleeve 3 and the U-shaped bend 11 are arranged crosswise with each other, that is, the side plate of one side of the connecting sleeve 3 is in the U-shaped bend 11, and the side plate of one side of the U-shaped bend 11 is inserted in the connecting sleeve 3, so that the connecting sleeve 3 is arranged at the position of the secondary door cover 2. One side of the U-shaped bend 11 is fixed on the main door frame 1, and the distance between the other side and the side of the U-shaped bend 11 away from the main door frame 1 remains fixed. In this way, a gap 4 for inserting the auxiliary door frame 2 is formed between the side of the connecting sleeve 3 away from the main door frame 1 and the U-shaped bend 11. Due to the cross-setting between the connecting sleeve 3 and the U-shaped bend 11, it is the connecting sleeve 3 rather than the U-shaped bend 11 that is exposed to the mortar side. In this way, the gap 4 will always be retained, thereby facilitating the insertion of the auxiliary door frame 2.
[0019] In order to further facilitate the insertion of the secondary door cover 2, the end of the connecting sleeve 3 on the side close to the secondary door cover 2 is bent 31 toward the side away from the slit 4. In this way, the size of the slit 4 opening is increased. Since the size of the slit 4 needs to maintain the clamping of the secondary door cover 2, this leads to inconvenience during insertion. The setting of the bend 31 increases the size of the slit 4 opening without affecting the internal clamping, thereby ensuring the convenience of inserting the secondary door cover 2.
[0020] In order to maintain the size of the gap 4, in this embodiment, the side of the connecting sleeve 3 close to the main door sleeve 1 is bonded to the main door sleeve 1. At the same time, a bonding protrusion is provided on the side wall of the connecting sleeve 3 close to the main door sleeve 1. In this way, the stability of the gap 4 is ensured by improving the firmness of the bonding, thereby ensuring the reliability of the insertion.
[0021] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
