Problems solved by technology

[0003] At present, in my country's prefabricated steel structure buildings, the steel beams mostly use H-shaped steel beams. Since the upper and lower surfaces of the H-shaped steel beams are flat, horizontal joints will be formed at the connection with the wall and floor. The horizontal joints not only affect Connection strength, and will cause problems such as noise reduction, poor thermal insulation performance

Embodiment 1

[0053] Such as figure 1 As shown, it is a prefabricated building disclosed by the present invention, which includes a main frame structure formed by steel columns 1 and steel beams 2, a wall formed by integral prefabricated wall panels, and a floor formed by integral prefabricated floor slabs 4, The integral prefabricated wall panels include prefabricated outer wall panels 31 and prefabricated inner wall panels 32, steel columns 1 and steel beams 2 are hot-rolled seamless special-shaped steel pipes (the processing technology is described in detail in Embodiment 4), and joint plates are used between them 7 and bolts 71; the steel column 1 is set between adjacent prefabricated wall panels, and the wet joint 5 is set between the steel column 1 and the end face of the prefabricated wall panel; the outer peripheral surfaces of the steel column 1 are all buried in the wet joint 5 , or part of the outer peripheral surface is flush with the surface of the prefabricated wall panel (tha...

Embodiment 2

[0079] One type of construction method, combining Figure 16 , including the following steps:

[0080] Step 1: Use the BIM platform to carry out three-dimensional design of the building structure for all parts and components, input relevant parameters for construction simulation, organize and process simulation on the construction site, construction installation training, construction simulation collision, construction simulation of complex nodes, and guide the parts machining of parts;

[0081] Step 2: Use special hot-rolled special-shaped seamless steel pipe columns and steel pipe beams to assemble layer by layer to form the steel structure frame system of the first floor of the prefabricated house; steel pipe columns and steel pipe beams are connected by gusset plates 7 and bolts 71;

[0082] Step 3: Use the special hot-rolled special-shaped seamless steel pipe column and the cavity of the steel pipe beam to install the water supply, drainage, sewage, and ventilation share...

Embodiment 3

[0092] The difference from Embodiment 2 is that when the top surface of the fifth wet joint 55 is level with the top surface of the prefabricated floor slab 4, the bottom surface of the prefabricated inner wall panel 32 is flat and is directly installed on the top of the fifth wet joint 55. In the face, the sixth to eighth steps become:

[0093] Step 6: Install the hollow high-strength lightweight concrete prefabricated inner wall panels 32 with concave-convex mortise and tenon structures on the three sides of the first layer;

[0094] The seventh step: pouring the wet joint 5 concrete of all joint nodes of the first layer to form the overall structure;

[0095] Step 8: Install the integral prefabricated doors, windows and other components of the first floor;

[0096] Step 9: Repeat the construction procedure from the second step to the eighth step above layer by layer until the structure installation is completed.

[0097] The prefabricated building structure is mainly a mi...

Abstract

The invention relates to a hot-rolled seamless steel tube beam, a connecting joint and a machining process of the hot-rolled seamless steel tube beam. The connecting joint comprises a pre-fabricated inner wall plate and a steel tube beam; the steel tube beam is a hot-rolled seamless H-shaped steel tube beam; an inner cavity of the steal beam is H-shaped; the upper surface and the lower surface ofthe H-shaped steel tube beam are inwards concave to form inserting-connection grooves; and the upper surface of the pre-fabricated inner wall plate located below the steel tube beam is provided with an inserting-connection portion which is matched with the inserting-connection grooves in shape; and the inserting-connection portion is inserted into the inserting-connection groove of the lower surface of the H-shaped steel tube beam. The steel tube beam is matched with the pre-fabricated inner wall plate in an inserting-connection mode, thus installation of the inner wall plate is convenient, the steel tube beam and the pre-fabricated inner wall plate are engaged, thus firmness is better, a horizontal through seam is prevented from forming in the top surface of the inner wall plate, and thethermal-insulation and noise-reduction properties of the structure are improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a hot-rolled seamless steel pipe beam, a connection node and a processing technology thereof. Background technique [0002] At present, the implementation of prefabricated buildings is the general trend. The development of prefabricated houses can improve the quality of common problems such as structural accuracy, leakage, and cracking, and improve the performance of sound insulation, heat preservation, and fire prevention, and facilitate system maintenance and updates. The prefabricated residence has a huge effect on energy saving and emission reduction, which improves the quality and efficiency of the residence, greatly improves the construction efficiency, shortens the construction period, and fully embodies the characteristics of "four sections and one environmental protection" of green buildings. [0003] At present, in my country's prefabricated steel struct...
