Description

Technical Field

[0001] The present invention relates to the technical field of house construction, and in particular to a house assembled steel tie beam connection assembly and a steel support structure. Background Art

[0002] In the field of housing construction technology, prefabricated steel structures are becoming a key development direction in modern architecture due to their advantages such as rapid construction, high strength, and environmental friendliness. These structures are typically assembled on-site from modular components such as vertical load-bearing columns (beams), horizontal tie beams, and roof support assemblies. Key requirements are structural strength, rigidity, and stability to withstand complex loads such as the building's own weight, wind loads, snow loads, and earthquakes.

[0003] However, the existing prefabricated steel tie beam connection and support structure still has the following significant defects: First, assembly efficiency is low: Traditional connection methods rely on extensive on-site welding or high-precision bolt positioning. For example, connecting horizontal tie beams to vertical main beams requires multiple welding points or complex bolt alignment, resulting in long construction times and high labor costs. Statistics show that welding accounts for over 40% of on-site steel structure construction time, and its quality is significantly affected by the welder's skill, which can easily lead to hidden dangers such as cold welds and deformation.

[0004] Second, poor foundation adaptability: Existing support structures have stringent requirements for foundation flatness. When the foundation is slightly tilted or uneven (common in mountainous areas and riverbanks), the base of the steel columns must be cut on-site or a concrete cushion must be poured to level it. This process is not only cumbersome (adding 3-5 days to the construction time), but also weakens the column base and affects the structure's ability to resist lateral movement. Especially for modular buildings, slight foundation deviations can lead to overall structural instability. To address this issue, the present invention proposes a prefabricated steel tie beam connection assembly and a steel support structure. Summary of the Invention

[0005] The present invention provides a house-assembly type steel tie beam connection assembly and a steel support structure, which solves the problem in the prior art that the steel structure relies on welding, resulting in a long construction period.

[0006] The technical solution of the present invention is as follows: a house-assembled steel tie beam connection assembly and a steel support structure, comprising a group of center beams and two groups of side beams, wherein the side beams and the center beam are arranged parallel to each other in the vertical direction, and is characterized in that a plurality of connecting members are provided on the center beam and the side beams, and the plurality of connecting members are equidistantly distributed along the vertical direction, and a cross beam is installed between two adjacent connecting members, and the bottoms of the center beam and the side beams are provided with support assemblies for supporting the center beam and the side beams, and the tops of the center beam and the side beams are provided with top beam assemblies.

[0007] Preferably, the support assembly includes a ground pile cast in the ground, the top of the ground pile is provided with a base that slides with the center beam and the side beam, the four corners of the base are provided with anchor bolts, the base is fixedly connected to the ground pile by the anchor bolts, and the four side walls of the base are fixedly connected with reinforcing ribs.

[0008] Preferably, plug-in plates are inserted on all four sides of the inner side of the base, and the plug-in plates are located between the center beam or side beam and the inner wall of the base. Ear plates are fixedly connected to the outer walls of the base. A pressure plate is provided on the top of the base, and fixing bolts are provided on all four sides of the pressure plate. The pressure plate is fixedly connected to the four ear plates through four fixing bolts.

[0009] Preferably, the pressure plate is an annular structure, and the pressure plate is sleeved on the corresponding center beam and side beam.

[0010] Preferably, leveling parts are provided around the bottom of the base, and the leveling parts include a pad. The side wall of the base is provided with a slot that slides with the pad. The pad is provided with an installation groove, and a fixing bolt 2 is provided in the installation groove. The pad is fixed to the bottom wall of the base by the fixing bolt 2.

[0011] Preferably, a threaded hole 1 is provided on the bottom wall of the holder for threadably cooperating with the second fixing bolt, and the center line of the mounting groove and the center line of the threaded hole 1 are located on the same vertical plane.

[0012] Preferably, the crossbeam includes a wide portion, both ends of the wide portion are fixedly connected to a narrow portion, and the narrow portion is fixedly connected to a corresponding connecting piece.

[0013] Preferably, the connecting part includes a positioning seat welded on the center beam and the side beam, the narrow part is clamped in the corresponding positioning seat, both ends of the inner side of the positioning seat are threadedly connected with a fixing bolt three, and the bottom of the narrow part is provided with a threaded hole two that is threadedly matched with the fixing bolt three.

[0014] Preferably, the top beam assembly includes a top seat mounted on the top of the center beam and the side beam, the top of the top seat is threadedly connected with four fixing bolts passing through the top seat, the top of the center beam and the side beam is provided with four threaded holes that threadably cooperate with the four fixing bolts, and a top beam is hinged between two adjacent top seats.

[0015] Preferably, the height of the central beam is greater than that of the side beams, and the cross-sectional areas of the central beam and the side beams are the same.

[0016] The working principle and beneficial effects of the present invention are: 1. Through the prefabricated connecting parts (including the narrow clamping design of the positioning seat and the crossbeam, combined with the three-point fastening of the fixing bolts), the traditional multi-point welding or complex bolt group hole operation is completely replaced; the top beam assembly adopts the top seat to connect the top of the main beam, and the installation can be completed with a single set of four fixing bolts. The top beam and the top seat are hinged to adapt to different roof inclination angles, which greatly simplifies the high-altitude operation process.

[0017] 2. The design of the leveling piece allows the horizontality of the base to be adjusted by inserting pads of different thicknesses into the slots, and then locking them with two fixing bolts. This can eliminate the impact of uneven foundations (such as mountains and riverbanks) on the verticality of the structure, and avoid the problems of construction delays and weakening of structural strength caused by traditional on-site cutting of steel columns or pouring of concrete pads.

[0018] 3. The built-in insert plate of the bracket fills the gap between the main beam and the bracket. The top annular pressure plate presses the main beam with the fixing bolts. Combined with the surrounding reinforcement, the compression and shear resistance are enhanced. The ground piles and the bracket are anchored by anchor bolts to form a solid foundation and the overall structure is stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] During installation, the steel structure of the house can be assembled by assembling each side beam 2 and the center beam 1 with the corresponding support assembly 3, then assembling each cross beam 5 to the connecting parts 4 on the side beam 2 and the center beam 1, and finally assembling the top beam assembly 6 to the top of the center beam 1 and the side beam 2. The overall structure is assembled without the need for multi-point welding, which greatly shortens the assembly time and thus improves the construction speed of the entire house system.

[0025] Furthermore, the support assembly 3 includes a ground pile 31 cast in the ground, and a base 32 is provided on the top of the ground pile 31 for sliding cooperation with the center beam 1 and the side beam 2. Anchor bolts 34 are provided at the four corners of the base 32, and the base 32 is fixedly connected to the ground pile 31 through the anchor bolts 34. The side walls of the base 32 are fixedly connected with reinforcing ribs 33, and plug plates 35 are inserted around the inner side of the base 32. The plug plates 35 are located between the center beam 1 or the side beam 2 and the inner wall of the base 32, and ear plates 36 are fixedly connected to the outer walls of the base 32. A pressure plate 37 is provided on the top of the base 32. The pressure plate 37 is a ring structure, and the pressure plate 37 is sleeved on the corresponding center beam 1 and side beam 2. Fixing bolts 38 are provided around the pressure plate 37, and the pressure plate 37 is fixedly connected to the four ear plates 36 through four fixing bolts 38.

[0026] The base 32 is used to install the center beam 1 and the side beam 2.

The design of the pad 391 can prevent the center beam 1 or the side beam 2 from tilting in uneven terrain, resulting in errors in the construction of the house system and a safety hazard.

[0029] Furthermore, the crossbeam 5 includes a wide portion 51 , and both ends of the wide portion 51 are fixedly connected to narrow portions 52 , and the narrow portions 52 are fixedly connected to corresponding connecting members 4 .

[0030] Furthermore, the connecting member 4 includes a positioning seat 41 welded on the center beam 1 and the side beam 2, and the narrow portion 52 is clamped in the corresponding positioning seat 41.

Then, one end of the pad 391 is fixed to the holder 32 by a second fixing bolt 393, so that the center beam 1 or the side beam 2 remains stable. The design of the pad 391 can prevent the center beam 1 or the side beam 2 from tilting in uneven terrain, which may cause errors in the construction of the house system and pose a safety hazard. Then, the narrow portion 52 of each beam 5 is clamped into the positioning seat 41, and then the narrow portion 52 of the beam 5 is fixed by the fixing bolt 3 42. This can achieve rapid assembly of the beam 5, the operation is very simple, and there is no need to perform multi-point welding on the beam 5, which greatly reduces assembly time and improves the construction efficiency of the house system. Finally, the top seat 61 is fixedly installed on the top of the corresponding center beam 1 and side beam 2 by fixing bolts 63 to realize the installation of the top beam 62. The overall installation process is very simple to operate, and the assembly of the top beam 62 can be completed by a single set of bolts.
