Description

Technical Field

[0001] This invention relates to the field of post-construction building space reuse technology, and in particular to a construction method for reusing a small, enclosed indoor space. Background Technology

[0002] During interior construction, after the main structure is completed, interior spaces are divided by subsequently built walls. Typical wall designs often use structural columns as base points, with the walls flush with the outer surfaces of the columns. However, this divides the interior space into small, unusable rooms, wasting valuable space. A targeted design is needed to balance aesthetics with efficient use of limited space, while also utilizing structural columns for secure enclosure. Summary of the Invention

[0003] This invention provides a construction method for reusing confined indoor spaces after sealing them off, which solves technical problems such as the aesthetics of the connection between the constructed wall and the interior wall, improving the utilization of confined spaces, and using structural columns for sealing and fixing connections.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A construction method for reusing confined indoor spaces after sealing them off, with the following specific steps: Step 1: Construct the main chamber structural columns, short walls, and long walls to form a rectangular main equipment chamber; the structural columns on one side are constructed before the main chamber structural columns are constructed. Step 2: Based on the revised dimensions of the secondary room, replan the installation of the subsequent walls; where, before the change, one end of the wall along its length was connected to the structural column and the side of the wall was flush with the side of the structural column, and the other end was perpendicularly connected to the short wall of the main room in a T-shape; the U-shaped space enclosed by the wall before the change, the short walls of the main room at both ends, and the structural columns was smaller than the dimensions of the secondary room. Step 3: Change the original wall to the changed wall (11) that is set along the main room wall. Seal the changed wall and the structural column with the sealing unit, and set the outer side of the sealing unit flush with the side of the structural column. Step 4: Set up secondary room structural columns along the extended line of the main room's long wall, and determine the position of the secondary room structural columns according to the position and thickness of the sealing unit; construct the modified wall between the main room structural columns and the secondary room structural columns; among them, set embedded parts on the secondary room structural columns, and connect them to the sealing unit through the embedded parts; Step 5: Divide the space of the secondary room into functional areas, unused areas, and storage areas within the space enclosed by the modified walls, main room short walls, structural columns, and sealing units. This completes the construction of the reuse of the small space that was sealed off later.

[0005] Furthermore, a well partition wall is installed between the short walls of the main chamber of the equipment main chamber. The area enclosed by the well partition wall, the short wall of the main chamber, and the long wall of the main chamber is used as the area for the installation of the hot water well.

[0006] Furthermore, the structural columns are reinforced concrete columns, and their dimensions are larger than those of the building columns; one side of the structural column is flush with the wall on the side of the main room door.

[0007] Furthermore, the modified wall is a masonry wall, with tie bars installed inside the masonry wall to connect with the steel bars in the auxiliary room structural columns; before the construction of the masonry wall, rebars are installed at the corresponding main room structural columns, and connected to the tie bars inside the masonry wall through the rebar installation. Among them, the connecting plate is pre-embedded when the auxiliary chamber structural column is poured, and the connecting plate is connected to the sealing unit.

[0008] Furthermore, the width of the secondary chamber structural column corresponds to the setting of the main chamber structural column, and the length corresponds to the setting of the design strength; the distance between the outer side of the secondary chamber structural column and the horizontal plane of the outer side of the structural column 8 corresponds to the thickness of the sealing unit.

[0009] Furthermore, the sealing unit includes a vertical keel, a horizontal keel vertically connected to the vertical keel, an insulation layer disposed on both sides of the frame connecting the vertical keel and the horizontal keel, a fireproof board disposed on the outside of the insulation layers on both sides, and a decorative layer on the outside of the fireproof board.

[0010] Furthermore, the vertical and horizontal keels are made of light steel keels. The top and bottom of the vertical keels are fixedly connected to the bottom surface of the upper floor slab and the top surface of the lower floor slab respectively by angle steel. The two ends of the horizontal keels are connected to the connecting plate inside the auxiliary room structural column and the structural column respectively by angle steel.

[0011] Furthermore, the insulation layer is a rock wool insulation layer with a thickness of not less than 50mm, and the fireproof board is a fireproof paper-faced gypsum board; the inner and outer decorative layers are uniformly set with the inner and outer surfaces of the modified wall.

[0012] The beneficial effects of this invention are reflected in: This invention, by modifying the design of the rear wall, ensures the integrity and aesthetics of the interior walls by seamlessly connecting it to the main room's long wall. It also integrates the original two-part space into a large space, effectively utilizing the limited wall space. The use of sealing units and structural columns ensures the enclosure and functional requirements of the integrated space. The use of structural columns in the secondary room ensures the connection between the modified rear wall and the sealing units, guaranteeing the overall integrity of the connection. Furthermore, the division of the secondary room space effectively utilizes the layout of the integrated space, achieving different functions. Therefore, this application solves the technical problems of aesthetics in the connection between the rear-constructed wall and the interior walls, improved utilization of limited spaces, and the use of structural columns for sealing and fixing connections. Other features and advantages of this invention will be set forth in the following description and will be apparent in part from the description, or may be learned by practicing the invention; the main objectives and other advantages of this invention can be realized and obtained by means of the methods particularly pointed out in the description.

The above-ground corridors are steel truss structures, with the No. 1 above-ground corridor connecting the three floors of Building 1 and Building 2.

[0017] After the construction of the heating well 7 in Building 1 was completed, one side of its space, combined with structural column 8, was designed as a hot water room. Figure 1 and Figure 2The following diagram further illustrates the construction method for reusing enclosed, confined indoor spaces. The specific steps are as follows: Step 1: Construct the main chamber structural column 2, the main chamber short wall 3, and the main chamber long wall 4 to form a rectangular equipment main chamber 1; among which, the structural column 8 on one side is pre-constructed before the main chamber structural column 2 is constructed.

[0018] In this embodiment, a well partition wall 6 is set between the short walls 3 of the main chamber 1. The area enclosed by the well partition wall 6, the short walls 3 and the long walls 4 of the main chamber is used as the area for setting the hot water well 7.

[0019] In this embodiment, the structural column 8 is a reinforced concrete column, and its size is larger than that of the building column; one side of the structural column 8 is flush with the wall of the main room door 5.

[0020] Step 2: Based on the revised dimensions of the secondary room 16, replan the installation of the subsequent walls; where, before the change, one end of the wall 9 is connected to the structural column 8 along its length and the side of the wall 9 is flush with the side of the structural column 8, and the other end is perpendicularly connected to the main room short wall 3 in a T shape; the U-shaped space enclosed by the wall 9, the main room short walls 3 at both ends, and the structural column 8 is smaller than the dimensions of the secondary room 16.

[0021] Step 3: Change the original wall 9 to the changed wall 11, which is set along the main room wall 4. Seal the changed wall 11 and the structural column 8 through the sealing unit 12, and set the outer side of the sealing unit 12 flush with the side of the structural column 8.

[0022] In this embodiment, the modified wall 11 is a masonry wall, and tie bars are installed in the masonry wall to connect with the steel bars in the auxiliary room structural column 10; before the construction of the masonry wall, the corresponding main room structural column 2 is reinforced with steel bars, which are then connected to the tie bars in the masonry wall; wherein, when the auxiliary room structural column 10 is poured, a connecting plate is pre-embedded, and the connecting plate is connected to the sealing unit 12.

[0024] Step 4: Set up the secondary room structural column 10 along the longitudinal extension line of the main room long wall 4, and determine the position of the secondary room structural column 10 according to the position and thickness of the sealing unit 12; construct the modified wall 11 between the main room structural column 2 and the secondary room structural column 10; wherein, embedded parts are set on the secondary room structural column 10 and connected to the sealing unit 12 through the embedded parts.

[0025] The sealing unit 12 includes a vertical keel 121, a horizontal keel 122 perpendicularly connected to the vertical keel 121, an insulation layer 123 on both sides of the frame connecting the vertical keel 121 and the horizontal keel 122, a fireproof board 124 on the outside of the insulation layers 123 on both sides, and a decorative layer 125 on the outside of the fireproof board 124. The vertical keel 121 and the horizontal keel 122 are light steel keels. The top and bottom of the vertical keel 121 are fixedly connected to the bottom surface of the upper floor slab and the top surface of the lower floor slab respectively by angle steel. The two ends of the horizontal keel 122 are connected to the inner connecting plate of the auxiliary room structural column 10 and the structural column 8 respectively by angle steel.

The inner and outer decorative layers 125 are uniformly set with the inner and outer finishes of the modified wall 11.

[0026] Step 5: Within the space enclosed by the modified wall 11, the main room short wall 3, the structural column 8, and the sealing unit 12, divide the space into functional areas 13, namely the water room, the unused area 14, and the storage area 15, thereby completing the construction of the indoor sealed-off narrow space for reuse.
