FIG. 4 is a schematic perspective view of the three-dimensional structure of FIG. 1 viewed from an oblique upward angle. From Figures 1 to 4, it can be seen that the mounting support consists of a supporting plate 1 with a rectangular bottom surface, a strip-shaped raised structure 2 fixed on both sides of the middle of the bottom surface of the supporting plate 1, and connectors located on both sides of the raised structure 2 3 composition.

On both sides of the upper surface of the supporting plate 1, there are ribs 11 along the length direction of the supporting plate 1, which are used to fit and connect with the grooves 10 of the building floor. The two ends of the supporting plate 1 are provided with a through hole I 12 through the supporting plate to cooperate with the T-shaped screw 9, so as to further realize the assembly connection with the building base plate 5 . Two opposite connecting pieces 3 are arranged on the lower surface of the pallet 1 . The opposite vertical sides of the connecting piece 3 and the bottom surface of the protruding structure 2 form a Π-shaped clamping portion 4 . At the same time, a threaded hole 34 and a through hole III 33 (the through hole can also be a threaded hole) are provided on the bottom surface of the connecting piece 3 . The connecting piece 3 is provided with a hollow structure II 31 with a section similar to an ellipse structure. At the same time, a through hole II 32 axially parallel to the supporting plate 1 is provided outside the hollow structure II 31 for connecting other hanging parts or installing cable-stayed fixing parts.

Fig. 5 is a three-dimensional structural schematic diagram of fixing a square tube on the bottom surface of the building floor by the mounting assembly including the support in Fig. 1 . FIG. 6 is a schematic perspective view of the three-dimensional structure of FIG. 5 from another angle. FIG. 7 is a front structural schematic view of FIG. 5 . FIG. 8 is an enlarged structural schematic diagram of the box in FIG. 7 . It can be seen from FIGS. 5-8 that the mounting support is mainly used for installing square pipes, and the mounting assembly including the mounting support is composed of a support 6 , a connecting rod 7 , a fastener 8 and a T-shaped screw 9 . The top of T-shaped screw rod 9 cooperates with the chute structure 51 that building base plate 5 forms and connects, and the bottom is fixedly connected by the through hole I 12 that has screw thread on the supporting plate 1 and the nut at the supporting plate 1 bottom. The connecting rod 7 is a long screw rod, the top end is connected with the support 6 through the threaded hole 34, and the low end is fixed through the threaded hole on the strip-shaped fastener 8.

At the same time, the fixed space formed by the bottom surface of the protruding structure 2, the opposite side of the connector and the upper surface of the fastener 8 firmly fixes the square pipe and the building floor as a whole, greatly increasing the stability of the hanging parts and effectively preventing long Suspension pendants fall off due to time shaking or severe shaking.

Specific implementation mode two

Fig. 9 is a schematic diagram of the front view of the installation support in Embodiment 2 of the present invention. FIG. 10 is a schematic side view of the structure of FIG. 9 . FIG. 11 is a schematic perspective view of the three-dimensional structure of FIG. 9 viewed obliquely downward. FIG. 12 is a schematic perspective view of the three-dimensional structure of FIG. 9 viewed from an oblique upward angle. From Figures 9 to 12, it can be seen that the difference between this specific embodiment and the first specific embodiment is that the bottom surface of the raised structure 2 is an arc-shaped structure, and the two ends of the bottom surface are combined with the opposite sides of the connector 3 to form a uniform curvature. Arc clamping part 4. At the same time, the shape of the hollow structure II 31 on the connector 3 is also different from that in the first embodiment. There are two through holes II 32 parallel to the plane of the supporting plate 1 along the vertical direction.

In addition, two connecting ears 13 are provided at both ends of the bottom surface of the supporting board 1 , and the direction of the connecting ears 13 is perpendicular to the length direction of the supporting board 1 . Connecting ear 13 is provided with through connecting ear hole 131 and is used for connecting with connecting parts such as connecting plate, thus a plurality of bearings are connected as a whole (as in Fig. 15, two adjacent bearings are connected by connecting plate One). At the same time, a trapezoidal groove 132 is also provided on each connecting ear to leave enough space for the installation of the T-shaped screw.

Fig. 13 is a front structural schematic view of the installation assembly including the installation support of Fig. 9 fixing the round pipe under the building floor. FIG. 14 is a schematic diagram of the enlarged structure at the block in FIG. 13 . FIG. 15 is a schematic side view of the structure of FIG. 13 . FIG. 16 is a schematic diagram of a partial three-dimensional structure of FIG. 13 . As can be seen from Figures 13 to 16, the mounting bracket and the mounting assembly were originally used to fix the round pipe. At the same time, the installation assembly differs from the installation assembly in Embodiment 1 in that the fastener 8 is not a strip plate but a hoop-shaped structure with a curvature consistent with the clamping portion 4, and the connecting section is provided with a screw thread The hole 34 is connected in series with the through hole or threaded hole of the connecting rod 7 .

This embodiment has exactly the same advantages as the first embodiment.

Specific implementation mode three

Fig. 17 is a schematic diagram of the front view of the installation support according to the specific embodiment. FIG. 18 is a schematic side view of the structure of FIG. 17 . FIG. 19 is a schematic perspective view of the three-dimensional structure of FIG. 17 viewed obliquely downward. FIG. 20 is a schematic perspective view of the three-dimensional structure of FIG. 17 viewed obliquely upward. It can be seen from FIGS. 17-20 that the difference between this specific embodiment and the first specific embodiment is that the protruding structure 2 is integrated, and a mesh-shaped hollow structure I 21 is provided inside to reduce the weight of the support structure. At the same time, the structure of the connector 3 has been greatly changed. The connector 3 is a combination of a round platform and a bent plate with an L-shaped cross section and a vertical side; the round platform is provided with a threaded hole 34 axially perpendicular to the supporting plate 1, and the free end of the L-shaped long side of the bent plate section is connected to the round platform. The side of the round platform is fixedly connected, and the opposite side of the round platform is connected to the vertical side of the curved plate.

Fig. 21 is a schematic diagram of the front view of the installation assembly including the installation support in Fig. 17 fixing the I-beam on the building floor. FIG. 22 is a schematic structural diagram of the enlarged block in FIG. 21 . FIG. 23 is a schematic perspective view of the three-dimensional structure of FIG. 21 . FIG. 24 is a partially enlarged structural schematic diagram of the box in FIG. 23 . As can be seen from Figures 21 to 24, the installation assembly is used to install I-beams or similar structures. At the same time, the installation assembly differs from the installation assembly in Embodiment 1 in that: the fastener 8 is composed of three sides bent twice. Wherein, the middle surface is the bottom surface, and the bottom surface is provided with a threaded hole for the connecting rod 7 to pass through. On both sides of the horizontal bottom surface are side surfaces that are bent obliquely upward in opposite directions. One side side is matched with the corner of the curved plate of the connector, and the other side top surface is the contact surface for fixing the bottom surface of the upper flange of the I-beam. The raised structure 2 The bottom plane of is the contact surface for fixing the upper surface of the upper flange of the I-beam. The structure of this assembly is used to connect the upper flange of the I-beam. At the same time, the structure of the assembly can be slightly changed, such as using the same or similar fasteners 8 as in the first embodiment, so as to support The lower flange of the I-beam.

Although this implementation mode is obviously different from the first two modes, it still has most of the advantages of the above two implementation modes. The only difference is that the single component adopts an open fixed space, and the stability may be slightly weaker. When the support components fixing the upper and lower flanges of the I-beam can be alternately arranged to realize the dislocation closed and fixed, so as to increase the stability of the I-beam. The advantages of the aforementioned two methods in terms of stability can also be obtained.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore The scope of protection of the present invention should be defined by the claims.
