Description

Technical Field

[0001] The present application relates to the technical field of prefabricated buildings, and in particular to a prefabricated supporting structure. Background Art

[0002] Prefabricated buildings are building components and accessories that are processed and manufactured in factories and transported to the construction site. They are then assembled and installed on site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures and steel structures. Steel structures have the advantages of light weight and easy installation. Steel structures have better ductility and good seismic resistance.

[0003] The related technology discloses an H-shaped steel column frame system, including an H-shaped steel column, a beam, a support plate, a cover plate, an outer rib and a reinforcing rib. The length of the H-shaped steel column is the floor height. The support plates are welded on three adjacent sides in the middle of the H-shaped steel column to ensure that the support plate is horizontal. The cover plate is horizontally welded above the support plate at a position one beam height away. The outer ribs are vertically welded on both sides of the support plate. The end plates are welded on the sides of the H-shaped steel column. Transverse ribs are welded on both sides of the web of the H-shaped steel column. The height positions of the transverse ribs are respectively on the upper surface of the support plate and the lower surface of the cover plate. The vertical ribs are vertically welded between the two transverse ribs. The beam adopts H-shaped steel, and the reinforced ribs are vertically welded in the middle of the beam. The prestressed steel strands pass through the reinforced ribs in the beam through the H-shaped steel column to the reinforced ribs in the beam on the other side, and are locked by locks.

[0004] However, the connection strength between the H-shaped steel column and the beam is greatly affected by the welding quality of the support plate, outer ribs and reinforcing ribs. When the welding quality is poor, the structure is prone to instability. Summary of the invention

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-6 This application is described in further detail.

[0027] An embodiment of the present application discloses an assembled support structure.

[0028] Embodiment 1: This embodiment discloses an assembled support structure. Figure 1, including an H-shaped steel column 1, which is vertically arranged. 1, 2, 3 or 4 columns 2 can be arranged around the H-shaped steel column 1. The H-shaped steel column 1 and the columns 2 are both steel sections. The outer periphery of the H-shaped steel column 1 is formed by pouring concrete by setting up a formwork. The H-shaped steel column 1 is located inside the concrete column 3, and a part of the column 2 is located inside the concrete column 3, and the other part is exposed from the side of the concrete column 3. The column 2 outside the concrete column 3 is used to connect a lightweight wall panel 4. A bottom plate 5 is arranged below the lightweight wall panel 4, and the bottom plate 5 can be formed by pouring concrete material. During construction, the H-shaped steel column 1 is installed first, and then the concrete column 3 above the bottom plate 5 is poured together with the bottom plate 5, so that the H-shaped steel column 1 and the lightweight wall panel 4 on the lower layer support the bottom plate 5 and the H-shaped steel column 1 above, and then the lightweight wall panel 4 is connected to the column 2. The cooperation between the concrete column 3 and the H-shaped steel column 1 can improve the supporting strength of the H-shaped steel column 1, and at the same time has corrosion resistance. In addition, the concrete column 3 and the bottom plate 5 are poured at the same time, which can save the time required for the concrete column 3 to reach the hardening strength after the concrete column 3 and the bottom plate 5 are poured successively, thereby improving the construction efficiency.

[0029] refer to Figure 2 The H-shaped steel column 1 includes a web 11 and flanges 12 connected to both sides of the web 11, and the column 2 includes a first connecting plate 21, a second connecting plate 22 and an intermediate plate 23. The first connecting plate 21 and the intermediate plate 23 are vertically arranged and arranged in a T-shape. The second connecting plate 22 is arranged on the side of the intermediate plate 23 away from the first connecting plate 21, and the intermediate plate 23 is connected to the middle of the second connecting plate 22, so that the first connecting plate 21, the intermediate plate 23 and the second connecting plate 22 form an I-shape. When in use, a support bolt 6 is arranged between the first connecting plate 21 and the H-shaped steel column 1, and the support bolt 6 is used to fix the column 2 to the H-shaped steel column 1. The first connecting plate 21 of the column 2 can be set at a position parallel to the web 11 or parallel to the wing 12. When the first connecting plate 21 is parallel to the web 11, the support bolts 6 penetrate the web 11 and the first connecting plate 21 at the same time, and fix the first connecting plate 21 at a position spaced apart from the web 11 through a plurality of nuts; when the first connecting plate 21 is parallel to the wing 12, the support bolts 6 penetrate the wing 12 and the first connecting plate 21 at the same time, and fix the first connecting plate 21 at a position spaced apart from the wing 12 through a plurality of nuts. When pouring the concrete column 3, the concrete column 3 completely wraps the H-shaped steel column 1 and places the first connecting plate 21 in the concrete column 3 to a depth of at least 2 cm. The middle plate 23 is exposed from the concrete column 3 and connected to the lightweight wall panel 4 through the second connecting plate 22. The lightweight wall panel 4 can be prefabricated with foam concrete.

[0030] refer to Figure 3 and Figure 4, a plurality of connection holes 231 are provided on the middle plate 23, and the connection holes 231 are used to install the connection components 7, and the lightweight wall panel 4 is fixed to the column 2 through the connection components 7. A connection groove 41 is provided on the side of the lightweight wall panel 4, and the connection groove 41 is arranged in a T shape, and the opening of the connection groove 41 faces the H-shaped steel column 1. During installation, the lightweight wall panel 4 is clamped on the second connection plate 22 from the upper end of the column 2, and the width of the T-shaped connection groove 41 is greater than the width of the middle plate 23 to avoid manufacturing errors causing difficulties in installing the lightweight wall panel 4. At the same time, a mounting hole 42 is provided on the lightweight wall panel 4 corresponding to the position of the connection hole 231, and the connection component 7 is located in the mounting hole 42 at the same time, so that the connection component 7 fixes the column 2 and the lightweight wall panel 4.

[0031] The connection assembly 7 includes a connection bolt 71 and a wedge 72. The diameter of the connection hole 231 is at least twice the diameter of the connection bolt 71, so that even if there is a large error in the position of the connection hole 231 and the mounting hole 42 during the installation process, the connection bolt 71 can still be inserted into the mounting hole 42 and the connection hole 231 at the same time. There are multiple wedges 72 arranged and arranged at both ends of the connection hole 231. The wedge 72 is inserted into the connection hole 231 from the smaller end, and the wedges 72 at both ends of the connection hole 231 are arranged in sequence to replace the staggered arrangement. After the connecting bolt 71 passes through the connecting hole 231, the nut is threadedly connected. Through the fixation of the nut and the connecting bolt 71, multiple wedge blocks 72 are gradually inserted into the connecting hole 231, and the wedge blocks 72 abut against the inner wall of the connecting hole 231 and the outer wall of the connecting bolt 71, so that the connecting component 7 fixes the lightweight wall panel 4 and the column 2. Even if the center position of the mounting hole 42 and the connecting hole 231 deviates during installation, it can still be compensated by the setting of the wedge blocks 72 to achieve the relative fixation of the position of the column 2 and the lightweight wall panel 4.

[0032] The connecting bolt 71 is also sleeved with an abutment pad 73, two of which are provided, and the multiple wedges 72 in each connecting assembly 7 are located between the two abutment pads 73, and the ends of the two abutment pads 73 abut against the wedges 72, so that when the wedges 72 slide radially, the wedges 72 can maintain good abutment with the abutment pads 73, and the axial direction of the connecting bolt 71 can be bent by the squeezing of the wedges 72, so that the connecting bolt 71 can pass through the center of the connecting hole 231 after deformation, and the connecting bolt 71 at this time is not easy to loosen after connection due to elastic deformation, and at the same time, the connection is kept stable under the action of the wedges 72. In order to facilitate the axial deformation of the connecting bolt 71, the length of the wedge 72 along the axial direction of the connecting bolt 71 can be increased.

The grouting sleeve 82 is provided corresponding to the upper end of the connecting steel bar 81. When the lightweight wall panel 4 is connected to the column 2, the grouting sleeve 82 is sleeved on the connecting steel bar 81. A pad 91 is provided below the lightweight wall panel 4. The pad 91 is located between the bottom plate 5 and the lightweight wall panel 4. The pad 91 adjusts the height of the lightweight wall panel 4 and facilitates the connection of the lightweight wall panel 4 to the column 2. Grouting material is injected into the grouting sleeve 82, so that the lower part of the lightweight wall panel 4 is fixedly connected to the bottom plate 5 through the fixing assembly 8.

[0034] The installation process of this embodiment: First, the H-shaped steel column 1 is set vertically, and then the concrete column 3 and the base plate 5 outside the H-shaped steel column 1 are cast at the same time, and then the lightweight wall panel 4 is hoisted and plugged into the column 2, and the upper and lower positions of the lightweight wall panel 4 and the column 2 are adjusted by the pad, and the lightweight wall panel 4 is fixedly connected to the column 2 by the connecting component 7, and the lightweight wall panel 4 is fixedly connected to the base plate 5 by the fixing component 8.

[0035] Embodiment 2: This embodiment discloses an assembled support structure. Figure 6 , which is different from the first embodiment in that: the fixing assembly 8 includes a flexible tie bar 83 and a nut, the flexible tie bar 83 includes a flexible section 831 and a steel section 832, the flexible section 831 uses a steel wire rope, the steel section 832 is fixed at both ends of the flexible section 831, one steel section 832 is cast in the bottom plate 5, and the other steel section 832 is threadedly connected to the nut, and an arc hole 43 is opened on the lightweight wall panel 4, one end of the arc hole 43 is located at the bottom of the lightweight wall panel 4, and the other end is located on the side wall of the lightweight wall panel 4. An elastic pad 92 is arranged below the lightweight wall panel 4, and the elastic pad 92 in this embodiment is an S-shaped continuously bent steel plate. When installing the lightweight wall panel 4, first insert the flexible tie rod 83 into the arc hole 43, and then tighten the nut. During the tightening process of the nut, the lightweight wall panel 4 presses the elastic pad 92 downward to deform the elastic pad 92. After the elastic pad 92 is deformed, the height of the lightweight wall panel 4 can be adjusted so that the installation hole 42 on the lightweight wall panel 4 can correspond to the connection hole 231 on the column 2, which is convenient for the installation of the connecting component 7.
