Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering construction, in particular to a rotatable truss device used for supporting a silo cantilever plate. Background Art

[0002] The most commonly used construction method for silos is slipform construction. Slipform construction is a construction method that uses a hydraulic lifting device to slide the formwork to cast vertical concrete structures. It is widely used in all walks of life in civil engineering. As long as these concrete structures have regular geometric cross-sections with unchanged boundaries in a certain direction, slipform technology can be used for fast and efficient construction or production.

[0003] However, for some special parts, such as the annular cantilever of the silo, the slipform construction cannot be continued because of its protruding structure. In the related art, there are two common construction methods for the cantilever panels of silos: one is to set up a floor-standing scaffolding, which has high safety risks and high cost investment; the other is to reserve embedded parts on the silo wall, and then weld the triangular support frame after the strength of the silo wall reaches 75%. This method has high requirements on the precision of the embedded parts, poor construction flow, and delayed construction period. Therefore, it is necessary to provide a rotatable truss device for supporting the cantilever panels of silos, which can solve the problems of high risks and costs of setting up floor-standing scaffolding, high requirements on the precision of reserved embedded parts, and delayed construction period in the prior art.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 6 A rotatable truss device for supporting the cantilever board of a silo comprises a hanging part 1, a column 2, a bottom supporting beam 3, a top supporting beam 5 and an adjusting slide 6; one end of the hanging part 1 is fixedly connected to the upper end of the column 2, and the other end of the hanging part 1 is detachably hung on the vertical concrete component 11 of the silo, so that the column 2 fits on the outer wall of the vertical concrete component 11, and a pair of columns 2 are vertically spaced; the bottoms of a pair of columns 2 are vertically connected with the bottom supporting beam 3, and the middle parts of a pair of columns 2 are vertically connected with the top supporting beam 5, and the adjusting slide 6 can be slidably inserted between the pair of bottom supporting beams 3 and the pair of top supporting beams 5, so that the adjusting slide 6 can be horizontally slidably arranged on the outside of the vertical concrete component 11 and supported under the cantilever board 12 of the silo.

[0026] The truss structure composed of a pair of columns 2, a pair of top supporting beams 5, an adjusting slide 6 and a pair of bottom supporting beams 3 is used to provide stable support for components such as templates for the construction of the cantilever board 12 below the cantilever board 12. Preferably, two columns 2 can be provided, and correspondingly, two top supporting beams 5 and two bottom supporting beams 3 are also provided, which are used to provide sliding limit and guidance for the adjusting slide 6 of the rectangular structure, so as to realize the sliding function of the adjusting slide 6 relative to the top supporting beams 5 and the bottom supporting beams 3, and then adjust the size of the truss structure to meet the construction support requirements of cantilever boards 12 of different sizes.

[0027] The hanging part 1 is used to hang the truss structure on the vertical concrete member 11, which is convenient for force transmission, and is convenient for the assembly and disassembly of the truss structure, and has high flexibility. There is no need to set up a ground scaffolding under the cantilever board 12, and there is no need to reserve embedded parts in the concrete of the vertical concrete member 11 under the cantilever board 12, which solves the problems of high risk and cost of setting up ground scaffolding, high precision requirements for reserved embedded parts, and delayed construction period in the prior art.

[0028] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 To Attachment Figure 6 A reinforcing rod 4 is provided between the bottom supporting beam 3 and the top supporting beam 5 located on the same column 2, and a plurality of reinforcing rods 4 are connected between the bottom supporting beam 3 and the top supporting beam 5 vertically and diagonally respectively.

[0029] The reinforcing rods 4 can improve the bearing capacity of the bottom supporting beam 3 and the top supporting beam 5, and improve the strength of the entire truss structure. The number and arrangement of the reinforcing rods 4 can be adaptively adjusted according to actual bearing requirements.

[0030] Please see attached Figure 4 The cross-section of the bottom supporting beam 3 is a U-shaped structure with an open top, so that the bottom of the adjusting slide 6 is slidably inserted into the U-shaped cavity of the bottom supporting beam 3; the cross-section of the top supporting beam 5 is an inverted U-shaped structure with an open bottom, so that the top of the adjusting slide 6 is slidably inserted into the inverted U-shaped cavity of the top supporting beam 5.

[0031] The U-shaped structure of the bottom supporting beam 3 can provide guidance and limitation for the bottom sliding of the adjusting slide 6, and the inverted U-shaped structure of the top supporting beam 5 can provide guidance and limitation for the top sliding of the adjusting slide 6, thereby ensuring the sliding stability of the adjusting slide 6.

[0032] Please refer to the attached drawings. The top and bottom of the adjustment slide 6 are provided with ear plates 7 with first mounting holes 701, and the bottom supporting beam 3 and the top supporting beam 5 are provided with positioning plates 10 with second mounting holes 9, so that the ear plates 7 are connected and fixed to the bottom supporting beam 3 and the top supporting beam 5 through the first mounting holes 701 and the second mounting holes 9 via the mounting parts 8.

[0033] When the adjusting slide 6 is slid and adjusted, the ear plate 7 slides synchronously with the adjusting slide 6, so that the first mounting hole 701 coincides with a second mounting hole 9 on the positioning plate 10, thereby facilitating the fixed connection between the positioning plate 10 and the ear plate 7 through the mounting member 8 via the second mounting hole 9 and the first mounting hole 701, thereby locking the adjusting slide 6 between the two top supporting beams 5 and the two bottom supporting beams 3, thereby ensuring the structural stability of the entire truss structure during the construction of the cantilever plate 12.

[0034] Please see attached Figure 2 The positioning plate 10 is arranged along the length direction of the bottom supporting beam 3 and the top supporting beam 5, and a plurality of second mounting holes 9 are arranged on the positioning plate 10 in a straight line with equal spacing.

[0035] The number and spacing of the second mounting holes 9 can be adaptively adjusted according to actual connection requirements to ensure that when the adjustment slide 6 slides to any position between the bottom support beam 3 and the top support beam 5, it can be locked between the bottom support beam 3 and the top support beam 5 through the second mounting holes 9 and the first mounting holes 701, with high adjustment flexibility.

[0036] Please see attached Figure 5 Several ear plates 7 are arranged at intervals on the top and bottom of the adjusting slide 6 , and the first mounting hole 701 is located in the middle of the ear plate 7 .

[0037] Preferably, ear plates 7 may be symmetrically arranged on both sides of the top and bottom of the adjusting slide 6 , and the ear plates 7 are located at one end and the middle of the adjusting slide 6 close to the silo to facilitate connection with the positioning plate 10 .

[0038] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 6 The hanging member 1 is an inverted U-shaped structure with an opening at the bottom, and the opening width is consistent with the thickness of the vertical concrete member 11.

[0039] The inverted U-shaped structure of the hanging part 1 can be bent according to the actual thickness of the vertical concrete member 11, which can prevent the truss structure from shaking after the hanging part 1 is hung on the vertical concrete member 11, thereby ensuring the setting stability and supporting reliability of the entire truss structure.

[0040] Please see attached Figure 1 To Attachment Figure 3 and attached Figure 6 The adjusting slide 6 includes a horizontal bar, a longitudinal bar, a vertical bar and an oblique bar. The horizontal bar, the longitudinal bar and the vertical bar are connected to form a rectangular parallelepiped structure, and the oblique bar is obliquely arranged in each surface of the rectangular parallelepiped structure.

[0041] The structure and size of the adjusting slide 6 can be adaptively customized according to actual load-bearing requirements to meet the support requirements for the cantilever board 12 during construction.

[0042] Please see attached Figure 1 To Attachment Figure 6 The manufacturing method and use method of the utility model are:

[0043] The hanging member 1 is made of steel bars bent into an inverted U-shaped structure, the column 2 is made of a square steel pipe, and one end of the steel bars of the inverted U-shaped structure is overlapped and welded in the square steel pipe.

[0044] The bottom support beam 3 and the top support beam 5 are both made of 6.5# channel steel, one end of which is welded and fixed to the bottom and middle of the column 2, and the other end of which extends horizontally outward. The reinforcing rod 4 is made of 5# channel steel and is welded between the bottom support beam 3 and the top support beam 5 in a Z shape.

[0045] The adjusting slide 6 can be formed by welding a round steel pipe, and the size of the adjusting slide 6 can be made according to the actual load requirement and the sliding adjustment requirement. The size of the round steel pipe should be smaller than the inner width of the 6.5# channel steel to ensure the flexibility of the telescopic function of the adjusting slide 6.

[0046] Ear plates 7 are welded to the top and bottom of both sides of the adjusting slide 6, and positioning plates 10 are welded to both sides of the top of the bottom supporting beam 3 and both sides of the bottom of the top supporting beam 5, and the mounting parts 8 are bolts and nuts. When the adjusting slide 6 slides to the point where the first mounting hole 701 coincides with the second mounting hole 9, the ear plates 7 are connected and fixed to the positioning plates 10 through the first mounting hole 701 and the second mounting hole 9 by bolts and nuts, so that the adjusting slide 6 is locked between the bottom supporting beam 3 and the top supporting beam 5.

[0047] When in use, the hook 1 is hooked on the top of the vertical concrete member 11 of the silo, so that a pair of columns 2 are attached to the outer wall of the vertical concrete member 11, and the top support beam 5 is located below the cantilever board 12. The range to be supported is determined according to the construction width of the cantilever board 12, and the adjustment slide 6 is pulled out in a direction away from the vertical concrete member 11 until the length of the adjustment slide 6 and the top support beam 5 meets the support range of the cantilever board 12.

[0048] The adjusting slide 6 is locked between the top supporting beam 5 and the bottom supporting beam 3. The lower end of the supporting column of the cantilever board 12 is placed on the top surface of the adjusting slide 6 and the top supporting beam 5, and the weight of the cantilever board 12 is transferred to the vertical concrete member 11 through the column 2 and the hanging member 1.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
