Abstract

The creation system provides a sill modification structure for installing a new threshold for a door leaf such as a soundproof door, an airtight door or a fire door in an original threshold, which mainly has a first one for embedding the original threshold. A frame strip, which cooperates with the first frame strip to clamp the second frame of the original threshold. The first frame strip has a first side strip corresponding to the inner frame surface of the original sill, and a first side frame strip connected to the side of the first side sill for abutting against the front side of the original sill; The two frame strip has a second frame strip for abutting against the original threshold, so that the first frame strip and the second frame strip enclose the two sides of the original threshold. In this way, the creation can install a new threshold on the original threshold, and does not need to remove the original threshold, and then converted into a soundproof door, an airtight door or a fire door.

Description

Threshold modification structure

This creation relates to a sill modification structure, especially a sill modification structure capable of converting an original sill into a soundproof door, an airtight door or a fire door.

Doors traditionally installed at the entrances and exits of buildings usually do not have the functions of sound insulation, airtightness and fire prevention. However, due to the revision of laws and regulations, people's fire prevention concepts are more comprehensive, and the requirements for quality of life are improved, so most of the newly built houses are soundproofed. Doors, airtight doors or fire doors. However, for old buildings such as old apartment buildings, the original doors are not soundproof, airtight and fireproof. Therefore, if necessary, the original threshold must be removed first, and then the installation is soundproof, airtight and A new threshold for fire protection and other functions, so that the new door can be installed in the door of the soundproof door, airtight door or fire door. However, the above-mentioned original threshold is usually covered by the cement wall of the house, and the demolition process is required in the process of dismantling, for example, the pneumatic cement is used to knock off the cement around the original threshold, so that the removal can be successfully completed.

According to the above-mentioned pneumatic chisel method, the original threshold is removed, and the construction process causes a lot of noise, sand and gravel pollution, and after the new threshold of sound insulation, airtightness or fireproof function is replaced, the cement must be repaired back. It can be seen that the traditional method of demolishing the original threshold is applied to the door sill reloading project of the old apartment building, which is a modification method that takes time and is expensive, and the modification cost is also quite expensive. Promotional applications for soundproof doors, airtight doors or fire doors. To this end, how to refit into a soundproof door, airtight door or fire door without dismantling the original threshold is a subject that the creative office should actively overcome.

In view of the shortcomings of the above-mentioned conventional threshold modification technology, the creator feels that he has not perfected it, exhausted his mind to study and overcome it, and based on his accumulated experience in the industry for many years, he developed a threshold modification structure. In order to achieve the original threshold for installation in various sizes, simple and rapid construction completion, quiet and clean construction process without pollution, and reduce the cost of modification.

The main purpose of this creation is to provide a sill modification structure, which can be converted into a soundproof door and an airtight door without removing the original sill by a two-frame design that can be installed on the original sill. Or the new threshold required for fire doors, and to achieve the original threshold for installation in various sizes, simple and rapid construction completion, quiet and clean construction process without pollution, and reduce the cost of modification.

In order to achieve the above and other objects, the present invention provides a sill modification structure for installing a new threshold for a soundproof door, an airtight door or a fire door in an original sill, preferably comprising: a first frame strip embedded in the original threshold, the first frame strip having a first side strip corresponding to the inner frame surface of the original threshold, and a first side strip connected to the first side strip a side surface of the first frame strip for abutting against the original sill; a second frame strip for engaging the first frame strip to clamp the original sill, the second frame strip having a a second frame strip abutting against the other side of the original sill; and a plurality of screws respectively screwed from the first side strip, the first side frame strip and the outer side of the second side frame strip, and The lock is attached to the original threshold.

In the above-mentioned sill modification structure, the second side frame strip of the second frame strip is connected to a second side strip, and the second side strip corresponds to and fits on the inner frame surface of the original sill.

In the above-mentioned sill modification structure, the first side strip forms a first buckle portion, and the second side strip forms a second buckle portion, and the first buckle portion and the second buckle portion are mutually engaged.

In the above-mentioned sill modification structure, the first side strip is formed with a door rib, one side of the door rib is combined with a zip strip, and the other side of the door rib forms the first buckle.

In the above-mentioned threshold modification structure, the first side strip of the first frame strip and the first side frame strip are vertically formed steel strips or aluminum extruded strips; and the second side strip of the second frame strip is The second frame strip is a vertically formed steel strip or aluminum extruded strip.

In the above-mentioned sill modification structure, a sealing strip covering the first surface strip and the second surface strip is further included, and the sealing strip covers the screw head of the screw.

In the above-described sill modification structure, the sealant strip is composed of the keloid which is coated and solidified after the screw is locked.

By modifying the design of the threshold of the creation, the first frame and the second frame can be wrapped around the original threshold without removing the original threshold, and the soundproof door, the airtight door or the fire can be provided again. The door is installed so that it can be used for installation in original sizes of various sizes, simple and rapid construction completion, quiet and clean construction process without pollution, and reduced conversion costs.

In order to fully understand the purpose, features and effects of this creation, the following specific examples, together with the attached drawings, provide a detailed description of the creation, as explained below:

Referring to FIG. 1, FIG. 2 and FIG. 3, it is a sill modification structure of the present invention, which is used for installing a new threshold for a soundproof door, an airtight door or a fire door in an original threshold 100.
