Description

A stage construction reinforcement performance truss Technical Field

[0001] This utility model relates to the technical field of performance trusses, specifically to a stage construction and reinforcement performance truss. Background Technology

[0002] A truss is a structure consisting of members connected to each other at both ends by hinges. Trusses are generally planar or spatial structures composed of straight members with triangular units. Truss members mainly bear axial tension or compression, thus making full use of the strength of the material. When the span is large, it can save material, reduce self-weight and increase stiffness compared to solid beams.

[0003] Existing stage trusses have drawbacks such as inconvenient installation and insufficient stability. Sandbags or other counterweights are generally needed to position the trusses to prevent them and the posters fixed on them from swaying due to strong winds, which could affect the safety of the performance. Summary of the Invention

[0004] The purpose of this utility model is to provide a stage construction reinforcement truss to solve the above-mentioned defects caused by the prior art.

[0005] A stage truss for strengthening performances includes a base, rectangular steel bars, transverse connecting rods, and counterweights. A slot seat is provided directly above the base, and a support structure is provided directly above the slot seat. The support structure is formed by rectangularly distributed rectangular steel bars fitting together with the transverse connecting rods, thereby completing the vertical assembly of the rectangular steel bars and transverse connecting rods. A positioning mechanism is provided on the outside of the base, which is positioned and connected to the bottom end of the base and the slot seat, so that the slot seat is fixedly installed on the ground surface, increasing the stability of the base during the support process.

[0006] Preferably, the support structure includes a first support plate, a rectangular steel bar, a second support plate, a transverse connecting rod, and fasteners. The first support plate is evenly spaced on the outside of the rectangular steel bar. A slot seat is welded to the bottom end of the rectangular steel bar. The second support plate is welded to the top end of the rectangular steel bar. A transverse connecting rod is attached to the top of the second support plate. A fastener is connected through the top end of the transverse connecting rod.

[0007] Preferably, the rectangular steel bar is connected to the outside of the base by a slot seat welded to its bottom end.

[0008] Preferably, the positioning mechanism includes a force-bearing panel, a threaded cone, a nut, an inner positioning groove, positioning holes, a slot seat, and a counterweight. The bottom end of the force-bearing panel is connected to the threaded cone, the outer side of the base is connected to the threaded cone, the bottom end of the base is welded to the force-bearing panel, the inner positioning groove is opened inside the base, the outer side of the force-bearing panel has rectangularly distributed positioning holes, the top of the base is provided with a slot seat, and the bottom of the slot seat is connected to a counterweight.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. Positioning is achieved by using transverse connecting rods and the outer side of the second support plate, and by using symmetrically arranged rectangular steel bars and the first support plate to ensure the stability of the rectangular steel bars and the first support plate during locking. The outer side of the rectangular steel bars is positioned by using the first support plate with equal spacing. The longitudinal horizontal bars must be set with equal spacing ≤400mm to ensure that the truss is subjected to uniform force and meets the safety bearing requirements.

[0013] 2. During use, the internal connection stability between the rectangular steel bar and the base is increased through the card slot seat and the inner positioning groove. At the same time, the inner positioning groove and the outer side of the counterweight are used for positioning. The counterweight is used to increase the internal positioning of the base. Meanwhile, the nut and the threaded cone are connected. The threaded cone is inserted into the soil, which increases the convenience of connecting the base with the flexible soil.

A slot seat 14 is provided directly above the base 1, and a support structure 7 is provided directly above the slot seat 14. The support structure 7 is fitted with the transverse connecting rods 5 through rectangularly distributed rectangular steel bars 3, thereby completing the vertical assembly of the rectangular steel bars 3 and the transverse connecting rods 5. A positioning mechanism 10 is provided on the outside of the base 1. The positioning mechanism 10 is positioned and connected to the bottom end of the base 1 and the slot seat 14, so that the slot seat 14 is fixedly installed on the ground surface, increasing the stability of the base 1 during the support process.

[0022] In this embodiment, the support structure 7 includes a first support plate 2, a rectangular steel bar 3, a second support plate 4, a transverse connecting rod 5, and fasteners 6. The first support plate 2 is evenly spaced on the outside of the rectangular steel bar 3. A slot seat 14 is welded to the bottom end of the rectangular steel bar 3. The second support plate 4 is welded to the top end of the rectangular steel bar 3. A transverse connecting rod 5 is attached to the top of the second support plate 4. A fastener 6 is connected through the top end of the transverse connecting rod 5. The top end of the first support plate 2 is positioned by the transverse connecting rod 5 to prevent the top end of the truss from shaking.

[0023] In this embodiment, the rectangular steel bar 3 is connected to the outside of the base 1 by a slot seat 14 welded to its bottom end. The slot seat 14 positions the outside of the base 1 to prevent the base 1 from shaking.

[0024] In this embodiment, the positioning mechanism 10 includes a force-bearing panel 8, a threaded cone 9, a nut 11, an inner positioning groove 12, a positioning hole 13, a slot seat 14, and a counterweight 15. The bottom end of the force-bearing panel 8 is connected to the threaded cone 9, the outer side of the base 1 is connected to the threaded cone 9, the bottom end of the base 1 is welded to the force-bearing panel 8, the inner positioning groove 12 is opened inside the base 1, the outer side of the force-bearing panel 8 is rectangularly distributed with positioning holes 13, the top of the base 1 is provided with a slot seat 14, and the bottom of the slot seat 14 is connected to the counterweight 15.

[0026] In this embodiment, the inner positioning groove 12 is connected to the outer side of the threaded cone 9 through the nut 11 provided inside, thereby improving the stability of the connection at the top of the threaded cone 9.

[0027] In practical applications, the construction of such stage trusses to reinforce performance structures includes the following tasks:

[0028] Step 1: The operator first inserts the threaded cone 9 vertically into the outside of the base 1, so that the base 1 fits against the surface of the soil. The threaded cone 9 is then rotated into the soil using an electric drill. At the same time, the nut 11 inside the base 1 is connected to the outside of the threaded cone 9 to position the outside of the threaded cone 9. This also makes the force-bearing panel 8 on the outside of the base 1 contact the ground, increasing the area of ​​force application.

[0029] Step 2: Then align the inner positioning groove 12 at the top of the base 1 with the counterweight 15 at the bottom of the slot seat 14, insert the counterweight 15 into the inner positioning groove 12, and at the same time make the outer side of the slot seat 14 fit with the outer side of the base 1. Then, tighten the base 1 and the outer side of the slot seat 14 with screws, so that the top of the slot seat 14 is welded to the bottom of the rectangular steel bar 3.

[0030] Step 3: After connecting the rectangular steel bars 3 in a rectangular distribution, multiple sets of support plates 2 are placed at equal intervals on the outside of the rectangular steel bars 3.
