Description

Technical Field

[0001] This invention relates to the field of prefabricated building installation, and in particular to a steel column installation structure for a box-type house with a pitched roof and its construction method. Background Technology

[0002] Prefabricated container houses are buildings constructed by assembling and connecting shipping containers as unit modules. The corner posts of the containers typically have rainwater hoppers on their top surfaces; these are inward-facing grooves on the top of the corner posts, using the interior of the posts as drainage channels to expel rainwater. For example... Figure 1 and Figure 2 As shown, since the drainage effect of the container's built-in rainwater hoppers is not ideal, the common practice in actual construction is to completely abandon the rainwater hoppers and build a steel-structured pitched roof on top of the container for systematic drainage. The traditional connection between the steel columns of the steel-structured pitched roof and the corner columns of the container is welding. The disadvantages of welding are: it reduces the overall assembly rate of the structure, which does not conform to the national advocacy of green and environmentally friendly construction concepts; in addition, welding quality control is difficult, fire hazards are significant, and the welding process also causes irreversible damage to the container's own structure.

[0003] Therefore, how to create a new installation structure and construction method for steel columns on the pitched roof of a box-type house is one of the important research and development topics at present. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a steel column installation structure for a box-type house with a pitched roof and its construction method, so as to avoid welding operations, improve on-site construction efficiency, eliminate fire hazards, and thus overcome the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a steel column installation structure for a box-type house with a sloping roof, including corner columns, T-shaped connectors, cover plates and steel columns;

[0006] The corner post is provided with a corner post top plate, and a rectangular rainwater hopper with a length greater than its width is provided on the corner post top plate;

[0007] The cover plate is installed on the top of the corner post. A rectangular hole is opened in the middle of the cover plate, and a snap-fit ​​part extends downward along the rectangular hole. The snap-fit ​​part is a rectangular cylinder that is enclosed on all four sides and runs through the top and bottom. The snap-fit ​​part is placed into the rainwater hopper of the top plate of the corner post. The outer wall of the snap-fit ​​part is tightly fitted with the inner wall of the rainwater hopper. A square groove is opened at the bottom of the side wall of the snap-fit ​​part.

[0008] The T-shaped connector includes an anti-pull-out key and a stud. The anti-pull-out key is set horizontally, and the stud is vertically welded to the middle of the anti-pull-out key, so that the stud and the anti-pull-out key form a T-shape. The T-shaped connector is placed into the rainwater hopper, the anti-pull-out key is inserted into the square groove and abuts against the bottom surface of the corner post top plate, and the stud extends upward to the outside of the rainwater hopper.

[0009] The bottom of the steel column is fixedly connected to a base plate with mounting holes. The stud passes through the mounting holes and is locked by a nut to fix the steel column.

[0010] As an improvement of the present invention, the two ends of the pull-out key of the T-shaped connector extend outward to form limiting keys, which are used to abut against the side wall around the square groove of the snap-fit ​​part.

[0011] Furthermore, a rubber gasket is bonded between the top surface of the pull-out key of the T-shaped connector and the bottom surface of the corner post top plate.

[0012] Furthermore, the number of T-shaped connectors inserted into the rainwater hopper of the corner post is two.

[0013] Furthermore, a washer is placed between the base plate of the steel column and the nut.

[0014] Furthermore, the steel column is set on the top of two closely attached corner columns and is connected and fixed to the T-shaped connectors in the rainwater hoppers of the two corner columns respectively.

[0015] In addition, the present invention also provides a construction method for constructing the above-mentioned steel column installation structure for a box-type house pitched roof, the specific steps of which include:

[0016] S1. Clean the top plates of the two adjacent corner posts, install the cover plate on the top plate of the corner posts, and insert the snap-fit ​​part into the rainwater hopper. Ensure that the outer wall of the snap-fit ​​part fits snugly against the inner wall of the rainwater hopper.

[0017] S2. Attach a rubber gasket to the top of the pull-out key of each T-shaped connector. Apply structural adhesive to both the upper and lower surfaces of the rubber gasket. The lower surface of the rubber gasket is bonded and fixed to the pull-out key, and the structural adhesive on the upper surface is used to bond and fix it to the corner post base plate in subsequent steps.

[0018] S3. Insert a T-shaped connector longitudinally into the rainwater hopper, rotate it 90° after insertion, and move it to the edge of the rainwater hopper while maintaining a horizontal position, leaving space for inserting another T-shaped connector.

[0019] S4. Insert another T-shaped connector longitudinally into the rainwater hopper and rotate it 90°. At the same time, insert the two T-shaped connectors into the square groove of the snap-fit ​​part, and pull the two T-shaped connectors upward to bond and fix the rubber gasket at the top of the pull-out key to the corner post base plate.

[0020] S5. After all T-shaped connectors are installed in place, remeasure the stud spacing. If the stud spacing does not meet the installation requirements, adjust the hole spacing of the mounting holes on the steel column base plate.

[0021] S6. Hoist the steel column to the top of two adjacent corner columns, slowly lower it so that the studs extending out of the rainwater hopper pass through the mounting holes on the base plate of the steel column, install the pads and screw in the nuts to lock them in place, and the installation is complete.

[0022] With this design, the present invention has at least the following advantages:

[0023] 1. The container corner posts and the steel columns of the steel structure pitched roof are completely detachable, which improves construction efficiency and is suitable for rapid deployment in emergency situations such as disaster relief.

[0024] 2. No welding work is required on the construction site, avoiding damage to the structure of the box itself during the welding process, and also making it easier to control the construction quality;

[0025] 3. The construction process is simple and convenient, with low construction difficulty, and is green and environmentally friendly. Attached Figure Description

[0041] Please see Figure 2 The present invention provides a steel column installation structure for a box-type house with a sloping roof, including a corner column 1, a cover plate 2, a T-shaped connector 3 and a steel column 4.

[0042] Please see Figure 3 The corner post 1 is a hollow rectangular post, a basic component of the container, vertically positioned at the four corners of the container for support. In this invention, a concealed rainwater hopper 12 is provided at the top of the corner post 1; that is, an inwardly recessed groove is formed on the top plate 11 of the corner post, the groove having no bottom surface and communicating with the interior of the corner post 1. The length of the rainwater hopper 12 is greater than its width, specifically 120mm in length, 60mm in width, and 150mm in depth. This invention abandons the drainage function of the rainwater hopper 12, utilizing it only as a foundation for fixing the cover plate 2, the T-shaped connector 3, and the steel post 4.

[0043] Please see Figure 4 and Figure 5 The cover plate 2 is mounted on the corner post top plate 11. The main structure of the cover plate 2 is a rectangular plate with a rectangular hole in the center and a snap-fit ​​part 21 extending downward from the rectangular hole. The snap-fit ​​part 21 is a rectangular cylinder that is enclosed on all four sides and extends vertically. The snap-fit ​​part 21 is inserted into the rainwater hopper 12 of the corner post top plate 11. The outer wall of the snap-fit ​​part 21 is tightly fitted with the inner wall of the rainwater hopper 12. A square groove 22 is formed at the bottom of the side wall of the snap-fit ​​part 21. The function of the square groove 22 is to allow the T-shaped connector 3 to be snapped into it, thereby limiting the horizontal movement of the T-shaped connector 3. In this embodiment, the square groove 22 is formed on the side wall along the length direction of the snap-fit ​​part 21.

[0044] Please see Figure 6The T-shaped connector 3 includes a stud 31, a pull-out key 32, and a limiting key 33. The pull-out key 32 is horizontally positioned, and the stud 31 is vertically welded to the middle of the pull-out key 32, forming a T-shape between the stud 31 and the pull-out key 32. The limiting key 33 is located at both ends of the pull-out key 32, extending outwards from the left and right sides of the ends of the pull-out key 32. The pull-out key 32 abuts against the bottom surface of the corner post top plate 11, providing pull-out resistance in the vertical direction. The limiting key 33 abuts against the sidewalls surrounding the square groove 22, allowing for horizontal displacement of the T-shaped connector 3.

[0045] Please see Figure 7 and Figure 8 To illustrate more clearly, Figure 8 The outer contour of one of the corner posts is hidden. The T-shaped connector 3 is inserted into the rainwater hopper of the corner post top plate 11 and abuts against the bottom surface of the corner post top plate 11. The pull-out key 32 of the T-shaped connector 3 is inserted into the square groove 22 of the locking part 21 on the cover plate 2. The stud 31 of the T-shaped connector 3 extends vertically upward outside the rainwater hopper 12.

[0046] In this embodiment, a rubber gasket 34 is also attached between the top surface of the pull-out key 32 and the bottom surface of the corner column top plate 11. During construction, the rubber gasket 34 is first attached to the top of the pull-out key 32, and then structural adhesive is applied to the upper surface of the rubber gasket 34. After the T-shaped connector 3 is adjusted and inserted into the square groove, the T-shaped connector 3 is pulled upward so that the upper surface of the rubber gasket 34 is bonded to the bottom surface of the corner column top plate 11.

[0047] Please see Figure 9 and Figure 10 The base plate 41 of the steel column 4 has an installation hole. The stud 31 on the T-shaped connector 3 passes through the installation hole and is locked and fixed by a nut. A pad 42 is placed between the nut and the base plate 41 of the steel column 4.

[0048] It should be noted that two T-shaped connectors 3 are inserted into the rainwater hopper 12 of each corner post 1. For connection strength and stress stability, the same steel column 4 is set on top of two closely attached corner posts 1, that is, it spans across the two corner posts 1. The two sides of the base plate 41 of the steel column 4 are connected and fixed to the T-shaped connectors 3 on the two corner posts 1 respectively. For the corner posts 1 located at the edge of the container house, other supporting structures need to be set up to ensure the installation of the steel column 4.

[0049] The present invention also provides a construction method, the specific construction steps of which include S1 to S6, which are described in detail below.

[0050] Step S1: Clean the two adjacent corner post top plates 11, and install the cover plate 2 onto the corner post top plate 11. Insert the snap-fit ​​part 21 into the rainwater hopper 12, ensuring that the outer wall of the snap-fit ​​part 21 fits snugly against the inner wall of the rainwater hopper 12.

[0051] Step S2: Attach a rubber gasket 34 to the top of the pull-out key 32 of each T-shaped connector 3. Apply structural adhesive to both the upper and lower surfaces of the rubber gasket 34 during attachment. The lower surface of the rubber gasket 34 is bonded and fixed to the pull-out key 32, and the structural adhesive on the upper surface is used for bonding and fixing to the corner post base plate 11 in subsequent steps.

[0052] Please see Figure 11 Step S3: Insert a T-shaped connector 3 longitudinally into the rainwater hopper 12, rotate it 90° after insertion, and move it to the edge of the rainwater hopper 12 while maintaining a horizontal state, leaving space for inserting another T-shaped connector 3.

[0053] Please see Figure 12 Step S4: Insert another T-shaped connector 3 longitudinally into the rainwater hopper 12 and rotate it 90°. At the same time, insert the two T-shaped connectors 3 into the square groove 22 of the snap-fit ​​part 21 and pull the two T-shaped connectors 3 upward to bond and fix the rubber pad 34 on the top of the pull-out key 32 to the corner post base plate 11.

[0054] Please see Figure 13 Step S5: After all T-shaped connectors 3 are installed in place, remeasure the stud spacing. If the stud spacing does not meet the installation requirements, adjust the hole spacing of the mounting holes on the steel column base plate 41.

[0055] Step S6: Hoist the steel column 4 above the two adjacent corner columns 1, and slowly lower it so that the stud 31 extending out of the rainwater hopper passes through the mounting hole on the steel column base plate 41. Install the pad 42 and screw in the nut to lock it in, and the installation is completed.

[0056] This invention features high construction efficiency, low construction difficulty, no welding operations, protection of the enclosure, and assurance of construction quality. It is also environmentally friendly and eliminates safety hazards.
