The prefabricated integrated housing structure includes frame columns and support columns, both arranged along a first direction. In a second direction perpendicular to the first direction, the frame columns are located on both sides of the support columns. Each support column is connected to its two sides by steel beams. The steel beams have holes penetrating both the upper and lower bottom surfaces, extending along the length of the beam.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a prefabricated integrated housing structure and its construction method. Background Technology

[0002] Prefabricated integrated housing refers to housing structures assembled on-site using prefabricated components, most of which need to be manufactured and processed in a workshop.

[0003] Compared to traditional houses, prefabricated integrated houses significantly reduce on-site pouring by assembling prefabricated components, resulting in faster construction speeds and making them suitable for winter construction. Currently, prefabricated integrated houses generally use steel frame structures, forming nodes at the connections between beams and columns, employing a combination of continuous columns and discontinuous beams at these nodes. Typically, prefabricated house structures include vertically installed prefabricated columns and steel beams perpendicularly connected to them. Each prefabricated column includes two sets of horizontally installed tie bolts, one end of which extends out of the prefabricated column. Correspondingly, the ends of the steel beams have plates for fixing to the prefabricated columns. The prefabricated columns have holes for the tie bolts to pass through; once the tie bolts pass through the corresponding holes, they are tightened with nuts, thus achieving relative fixation between the steel beams and the prefabricated columns.

[0004] During the implementation process, the inventors discovered that the above-mentioned prior art has at least the following defects: the steel beams are installed on both sides of the column by tie bolts, which requires high assembly precision during the construction of the house, resulting in low construction efficiency. Summary of the Invention

[0005] This application provides a prefabricated integrated housing structure and its construction method to solve the technical problem of low efficiency in the existing housing construction process.

[0006] To address the aforementioned technical problems, this invention discloses a prefabricated integrated housing structure, comprising frame columns and support columns. The frame columns and support columns are arranged along a first direction. In a second direction perpendicular to the first direction, the frame columns are located on both sides of the support columns. The frame columns on both sides of each support column are connected by steel beams. The steel beams have holes that penetrate the upper and lower bottom surfaces, extending along the length of the steel beams. The upper part of the support columns passes through the holes in the steel beams, which in turn penetrate the steel beams vertically. The steel beams have slots, in which baffles engage. The baffles are arranged along the first direction and fixed to the support columns located at both ends by bolts.

[0007] Because the steel beams have holes that penetrate both the top and bottom surfaces, the frame columns and steel beams can be assembled first during the house assembly process. Then, the upper end of the support column can be passed through the holes in the steel beam and fixed relative to the steel beam and baffle. This avoids the need to use tie bolts at the joints between the steel beam and the support column, thus improving construction efficiency.

[0008] Furthermore, the lower ends of the frame columns and support columns are fixed to the ground by bases, which are at the same horizontal level. Thus, the installation positions of the frame columns and support columns can be determined by the position of the bases before the house is assembled. In addition, the assembly accuracy of the house can be ensured by fine-tuning the position of the bases during the assembly process.

[0009] Furthermore, each steel beam includes two parallel elongated steel plates. Both ends of the two elongated steel plates are welded and fixed to a square steel plate to form a frame structure. The square steel plate has through holes for bolts to pass through. The steel beam is fixed to the upper end of the frame column by bolts. Since the steel beam has a frame structure, its weight is relatively small, making it more convenient to assemble.

[0010] Furthermore, the top of the frame column is stepped, with the stepped surface of the frame column supporting the bottom of the steel beam end.

[0011] Furthermore, each row of frame columns is provided with a transverse beam A along the first direction above it. The transverse beam A has a rectangular cross section. The bottom and one side of the transverse beam A are in contact with the frame column, and the other side of the transverse beam A is in contact with the end of the steel beam. Bolts are passed through the frame column, the transverse beam A, and one end of the steel beam in sequence and then tightened with nuts. The transverse beam A can connect the frame columns in the first direction, making the structure more stable and improving the assembly accuracy.

[0012] Furthermore, the support column includes a stop portion consisting of two steel plates and a support portion located between the two steel plates. The support portion has a square cross-section, and the upper end of the support portion is lower than the upper end of the stop portion and forms a groove.

[0013] Furthermore, the two sides of the support column are in contact with the two steel plates of the steel beam, and the upper part of the support column has a transverse beam B arranged along the first direction. The transverse beam B has a rectangular cross section and is engaged in the groove at the upper end of the support column.

[0014] On the other hand, the present invention also discloses a method for constructing prefabricated integrated houses, which mainly includes the following steps:

[0015] S1. Install the frame column, fix the base on the horizontal ground, fix the base to the ground, and install the frame column vertically on the base.

[0016] S2. Install transverse beam A, placing transverse beam A above the frame column along the first direction;

[0017] S3. Install the steel beams. Place both ends of the steel beams above the frame columns, and tighten them with nuts after passing through the frame columns, transverse beam A, and the ends of the steel beams with bolts.

[0018] S4. Install the support column. Install a baffle in the slot above the steel beam along the first direction, and then install the support column. When the lower end of the support column is fixed to the base and the side of the support column contacts the baffle, install another baffle in the slot above the steel beam so that the baffle clamps the support column. Then fix the support column near both ends to the baffle with bolts.

[0019] S5. Install the transverse beam B. Place the transverse beam B in the groove at the upper end of the support column along the first direction and fix it to the upper end of the support column with bolts.

[0020] As can be seen from the above technical solutions, the present invention has at least the following technical effects or advantages:

[0021] Because the steel beams have holes penetrating both the top and bottom surfaces, during the house assembly process, the frame columns and steel beams can be assembled first. Then, the upper ends of the support columns can be passed through the holes in the steel beams and fixed relative to the beams and baffles. This avoids the need for tie bolts at the joints between the steel beams and support columns, improving construction efficiency. Since the lower ends of both the frame columns and support columns are fixed to the ground via bases, their installation positions can be determined before assembly by the location of the bases. Furthermore, during assembly, the position of the bases can be fine-tuned to ensure the assembly accuracy of the house. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0031] This invention discloses a prefabricated integrated house; please refer to [link / reference]. Figure 1 , Figure 2 The prefabricated integrated house includes frame columns 1 and support columns 2 arranged along the first direction x. In the second direction y, which is perpendicular to the first direction x, the frame columns 1 are located on both sides of the support columns 2. The frame columns 1 on both sides of each support column 2 are connected by a steel beam 3. The upper end of the support column 2 passes through the steel beam 3 from bottom to top and is fixed relative to the steel beam 3.

[0032] like Figure 3 , Figure 4 As shown, the lower ends of the frame columns 1 are all fixed to the ground by bases 6, which are at the same horizontal level. The top of the frame column 1 is stepped, and the stepped surface of the top of the frame column 1 can support the lower end of the steel beam 3. Above each row of frame columns 1, there is also a transverse beam A7 arranged along the first direction x. The transverse beam A7 has a rectangular cross section. The bottom of the transverse beam A7 contacts the stepped surface of the frame column 1, and the two sides of the transverse beam A7 contact the side of the frame column 1 and the end face of the steel beam 3, respectively.

[0033] like Figure 5As shown, each steel beam 3 comprises two parallel elongated steel plates, both ends of which are welded to square steel plates, thus forming a frame-like structure. This ensures that the steel beam 3 has a light weight, facilitating its installation above the frame column 1. The square steel plate has through holes for bolts to pass through. Correspondingly, through holes for bolts are also provided on the transverse beam A7 and the frame column 1. During the installation of the steel beam 3, bolts are sequentially passed through the corresponding holes on the frame column 1, transverse beam A7, and steel beam 3 before being tightened.

[0034] More specifically, each steel beam 3 has a hole penetrating both the upper and lower bottom surfaces for the support column 2 to pass through. This hole extends along the length of the steel beam 3, and the upper part of the support column 2 passes through the hole in the steel beam 3 to pass through it vertically. The steel beam 3 is provided with a slot 4, and a baffle 5 is engaged and installed in the slot 4. The baffle 5 is set along the first direction x and can be fixed to the support column 2 near both ends by bolts.

[0035] like Figure 6 As shown, the support column 2 includes a stop portion 8 composed of two steel plates and a support portion 9 located between the two steel plates. The two sides of the support portion 9 contact the two steel plates of the steel beam 3 respectively. The support portion 9 has a square cross-section, and its upper end is lower than the upper end of the stop portion 8, forming a groove. Above the support column 2 is a transverse beam B10 arranged along a first direction x. The transverse beam B10 has a rectangular cross-section and engages with the groove at the upper end of the support column 2.

[0036] The prefabricated integrated house is constructed using the following steps:

[0037] S1. Install frame column 1, fix base base 6 on horizontal ground, fix base base 6 to ground, and install frame column 1 vertically on base base 6.

[0038] S2. Install the transverse beam A7, placing the transverse beam A7 above the frame column 1 along the first direction x;

[0039] S3. Install steel beam 3. Place both ends of steel beam 3 above frame column 1. Secure it with bolts through the ends of frame column 1, transverse beam A, and steel beam 3 respectively, and then tighten it with nuts.

[0040] S4. Install support column 2. Install a baffle 5 in the slot 4 above the steel beam 3 along the first direction x. Then install support column 2. When the lower end of support column 2 is fixed to the base 6 and the side of support column 2 contacts baffle 5, install another baffle 5 in the slot 4 above the steel beam 3 so that baffle 5 clamps support column 2. Then fix support column 2 near both ends to baffle 5 with bolts.

[0041] S5. Install the transverse beam B10. Place the transverse beam B10 in the groove at the upper end of the support column 2 along the first direction x and fix it to the upper end of the support column 2 with bolts.

[0042] More specifically, the base 6 has square slots, the length and width of which are slightly larger than the length and width of the lower end of the frame column 1 or support column 2. After the frame column 1 is installed, when installing the transverse beam A7, the transverse beam A7 is placed above the frame column 1, and then the frame column 1 is slightly adjusted along the second direction y so that the frame column 1 is in contact with the transverse beam A7. After the transverse beam A7 and steel beam 3 are installed, concrete is filled between the base and the slots of the frame column 1, which facilitates the installation of the transverse beam A7 and steel beam 3.

[0043] After the steel beam 3 is installed, the baffle 5 is first snapped into the slot 4 of the steel beam 3, and then the support column 2 is installed. When installing the support column 2, the support column 2 is first tilted at a certain angle and passed obliquely upward through the steel beam 3. Then the bottom of the support column 2 is placed into the slot of the base 6, and the support column 2 is slightly adjusted along the second direction y so that the side of the upper end of the support column 2 contacts the baffle 5. After the baffle 5 and the support column 2 are fixed, concrete is filled between the base and the frame column 1, which facilitates the installation of the support column 2.
