Description

Technical Field

[0001] The utility model relates to the field of building assembly, in particular to a prefabricated assembled grandstand. Background Art

[0002] Grandstands are an indispensable structure in sports stadiums and large-scale theatrical performance venues. Currently, grandstands are generally divided into two types based on construction technology: cast-in-place and prefabricated. Traditional cast-in-place stands offer strong structural stability, but they require a long construction period, require a lot of manpower, and are subject to significant constraints from weather and location conditions, hindering rapid construction and cost control. Traditional prefabricated stands have a short construction period, but during the hoisting process, they often generate significant lateral concentrated stress on the load-bearing structure that comes into contact with the stands first, thereby undermining the stability of the load-bearing structure. Furthermore, traditional prefabricated stands have poor integration with the load-bearing structure and lack a reliable connection to the load-bearing structure, hindering overall stress distribution. Utility Model Content

[0003] The purpose of the utility model is to provide a prefabricated assembled stand, which has a fast assembly process, a strong structural integrity, and can avoid damage to the load-bearing structure caused by the lateral force generated by hoisting.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A prefabricated assembled grandstand, comprising a prefabricated grandstand panel extending obliquely, wherein the upper edge bottom of the prefabricated grandstand panel is supported by a plurality of corbel columns, and the lower edge bottom of the prefabricated grandstand panel is supported by a plurality of anti-side columns, wherein the prefabricated grandstand panel, the corbel columns and the anti-side columns are all reinforced concrete structures;

[0006] The column reinforcement of the anti-side column is located in the middle of the anti-side column, and the upper end of the column reinforcement extends upward from the top surface of the anti-side column. The lower edge of the prefabricated stand board is provided with a lower edge notch that passes through the upper end of the column reinforcement. Two anti-side components are also embedded in the anti-side column, and the two anti-side components are respectively arranged on the left and right sides of the anti-side column reinforcement.

[0007] The anti-side component includes an anti-side steel plate extending forward and backward and a plurality of anchor bars fixed to the bottom of the anti-side steel plate. The top surface of the anti-side steel plate is provided with a downwardly concave matching slot, and the bottom of the prefabricated stand panel is provided with a matching plug-in portion corresponding to the matching slot.

[0008] Compared with the prior art, the advantages of the present invention are:

[0009] 1. Through the cooperation of the embedded anti-side components in the anti-side columns and the plug-in parts in the prefabricated stand panels, the lateral stress generated by the prefabricated stand panels during the lifting process can be evenly dispersed to the anti-side columns, effectively avoiding the damage to the load-bearing structure caused by the lateral concentrated stress generated during the lifting process, and realizing the reliable connection of the entire stand structure;

[0010] 2. By setting up the lower edge cast-in-place area, connecting steel bars and steel baffles, concrete can be poured into the lower edge cast-in-place area in subsequent construction, thereby realizing the integrated combination of the prefabricated stand slab and the anti-side column, and improving the overall stability of the prefabricated stand.

DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0021] like Figure 1-8 The figure shows a schematic diagram of an embodiment of a prefabricated assembled stand provided by the present invention:

[0022] A prefabricated assembled grandstand, comprising a prefabricated grandstand panel 1 extending obliquely, wherein the upper edge bottom of the prefabricated grandstand panel 1 is supported by a plurality of corbel columns 2, and the lower edge bottom of the prefabricated grandstand panel 1 is supported by a plurality of anti-side columns 3, wherein the prefabricated grandstand panel 1, the corbel columns 2 and the anti-side columns 3 are all reinforced concrete structures;

[0023] The column reinforcement of the anti-side column 3 is located in the middle of the anti-side column 3, and the upper end of the column reinforcement extends upward from the top surface of the anti-side column 3. The lower edge of the prefabricated stand board 1 is provided with a lower edge notch that passes through the upper end of the column reinforcement. Two anti-side components 4 are also embedded in the anti-side column 3. The two anti-side components 4 are respectively arranged on the left and right sides of the column reinforcement of the anti-side column 3;

[0024] The anti-side component 4 includes an anti-side steel plate 41 extending forward and backward and a plurality of anchor bars 42 fixed to the bottom of the anti-side steel plate 41. The top surface of the anti-side steel plate 41 is provided with a downwardly recessed matching slot 411, and the bottom of the prefabricated stand panel 1 is provided with a matching plug-in portion 101 corresponding to the matching slot 411.

[0025] The anchor bars 42 are arranged at intervals in front and back.

[0026] The corbel column 2 is a prefabricated reinforced concrete component, and the anti-side column 3 can be selected as a prefabricated reinforced concrete component or a cast-in-place component according to the actual construction period and calculated load.

[0027] The plurality of corbel columns 2 and the plurality of anti-side columns 3 are arranged in a one-to-one correspondence front to back.

[0028] Several of the corbel columns 2 are supported on the upper edge of the prefabricated stand board 1 at intervals on the left and right according to the span design of the prefabricated stand board 1, and the corbel columns 2 located on the left and right sides should support the upper edge corners of the prefabricated stand board 1 respectively.

[0029] The front side of the lower edge notch is flush with the front side of the prefabricated grandstand board 1, and the anti-side column 3 is also pre-embedded with a steel baffle 5 to block the front side of the lower edge notch. Each steel baffle 5 and the prefabricated grandstand board 1 together enclose the lower edge notch to form a lower edge cast-in-place area 6.

[0030] The lower edge reinforcement of the prefabricated grandstand panel 1 extends to the lower edge cast-in-place area 6, and the steel baffle 5 is penetrated by a number of connecting steel bars 7 extending forward and backward. A steel sleeve 701 is connected between the rear end of the connecting steel bar 7 and the lower edge reinforcement, and a nut locking part 702 is screwed on the front end of the connecting steel bar 7 passing through the steel baffle 5.

[0031] A plurality of connecting steel bars 7 are arranged at intervals on the left and right, and the connecting steel bars 7 are preferably inserted into the spacing between the column bars of the anti-side column 3.

[0032] The steel baffle 5 is pre-drilled with through holes for the connecting steel bars 7 to pass through.

[0033] The bottom surface of the slot 411 is a slope that slopes downward from back to front, and the rear end height of the slot 411 is flush with the top surface of the anti-side column 3. The bottom surface of the corresponding plug-in part 101 is also a slope that slopes downward from back to front, so as to achieve sliding friction when the prefabricated stand board 1 and the anti-side column 3 are in contact during hoisting, which is more conducive to construction hoisting and the dispersion of lateral stress.

[0034] The upper end of the column reinforcement of the corbel column 2 extends upward from the top surface of the corbel column 2, and the upper edge of the prefabricated grandstand panel 1 is provided with an upper edge notch that passes through from top to bottom corresponding to the upper end of its column reinforcement, and a steel mesh 8 connected to the steel bars in the prefabricated grandstand panel 1 is provided in the upper edge notch.

[0035] An external formwork is also provided at the edge of the upper edge gap, and the external formwork and the prefabricated stand board 1 enclose the upper edge gap and form an upper edge cast-in-place area.

[0036] The middle section of the top surface of the prefabricated stand panel 1 is provided with a plurality of steps along its extension direction.

[0037] The construction method of this utility model is roughly as follows:

[0038] S1: Hoist the corbel column 2 and the anti-side column 3 to the designed position.

[0039] S2: Hoist the prefabricated grandstand panel 1, ensure that the lower edge notches are aligned with the column reinforcement of each anti-side column 3, and the upper edge notches are aligned with the column reinforcement of each corbel column 2, and make the plug-in part 101 of the prefabricated grandstand panel 1 plug into the matching slot 411 of the anti-side member 4 (during the hoisting process, the lower edge side of the prefabricated grandstand panel 1 should first contact the anti-side column 3. At this time, the lateral stress generated by the hoisting of the prefabricated grandstand panel 1 is transferred from the plug-in part 101 to the anti-side steel plate 41, and dispersed to the overall anti-side column 3 through the anchor bar 42).

[0040] S3: After the prefabricated grandstand panel 1 is hoisted into place, the steel baffle 5 embedded in the anti-side column 3 blocks the front side of the lower edge gap and encloses the prefabricated grandstand panel 1 to form a lower edge cast-in-place area 6, and then the connecting steel bars 7 that are connected to the lower edge steel bars of the prefabricated grandstand panel 1 are passed through the steel baffle 5.

[0041] S4: According to actual design requirements, an external formwork is set up at the edge of the upper edge gap, so that the external formwork and the prefabricated stand board 1 enclose the upper edge gap and form an upper edge cast-in-place area.

[0042] S5: pouring concrete in the lower edge cast-in-place area 6 and the upper edge cast-in-place area to achieve the overall combination of the prefabricated stand slab 1, the corbel column 2 and the anti-side column 3.
