Abstract
Description
Technical Field
[0001] This utility model relates to the field of molded column technology, specifically to a quick-cast, non-removable molded column. Background Art
[0002] Precast concrete columns are a type of modern building construction material widely used on construction sites. They are columns made by casting concrete using steel molds, and are also called steel formwork columns, template columns, steel mold columns, etc. The main features of precast concrete columns are that they are easy to produce and install, enabling efficient and rapid construction and providing good economic benefits.
[0003] However, when using existing formwork-free columns, concrete is usually poured on all four sides of the column. However, the concrete cannot be fully vibrated during pouring. Insufficient vibration will result in the concrete being loose and having too low a density, which will affect the strength of the concrete and have a certain impact on the quality of the building. In addition, the pouring time is too long, which will have a certain impact on the construction efficiency. Therefore, a formwork-free column that can be poured quickly is needed. Utility Model Content
[0004] The main purpose of this utility model is to provide a quick-cast, formwork-free shell column. This utility model solves the problems of existing formwork-free shell columns, such as the inability to fully vibrate the poured concrete, long pouring time, and insufficient compaction, by setting galvanized closing mesh, steel wire mesh, galvanized steel mesh, tie members, stirrup A, stirrup B, and main reinforcing bars.
[0005] The technical solution adopted by this utility model to solve its technical problem is a quick-cast, formwork-free shell column, including main reinforcing bars. One side of the main reinforcing bars is welded with a stirrup A to increase strength. The outside of the stirrup A is welded with a stirrup B to increase strength. A galvanized mesh for closing treatment is welded to the outside of the main reinforcing bars. Tie members for fixing and stabilizing the galvanized mesh are provided on the outside of the galvanized mesh. A steel wire mesh to increase the strength of the galvanized mesh is welded to the inside of the galvanized mesh. A galvanized steel mesh to increase the connection strength is welded to the outside of the main reinforcing bars.
[0006] By adopting the above technical solution, the galvanized wire mesh is first fixed to one side of the mold column, and then the galvanized wire mesh is fixed more stably using tie-fitting parts. Then, the other three sides of the mold column are poured, so that the poured concrete can be fully vibrated, reducing the pouring time and increasing the density of the pouring.
[0007] After the galvanized wire mesh is fixed to the outside of the formwork column, the steel wire mesh inside the galvanized wire mesh increases the strength of the galvanized wire mesh. At the same time, galvanized steel mesh is welded to the four external corners of the formwork column, which increases the connection strength of the formwork column and thus prevents the formwork column from deforming during the pouring process.
[0008] Specifically, the inner side of the galvanized steel mesh is welded with reinforcing ribs to improve the strength of the galvanized steel mesh.
[0009] By adopting the above technical solution, after the galvanized steel mesh is fixed to the external corner of the mold column, the reinforcing ribs welded inside the galvanized steel mesh increase the strength of the galvanized steel mesh and prevent the galvanized steel mesh from bending and deforming.
[0010] Specifically, the stirrup B is fitted with a pad to shield the weld joint.
[0011] By adopting the above technical solution, after stirrup B is connected to stirrup A, a spacer is placed on the outside of stirrup B, and then the spacer is moved to the position where stirrup B is connected, so as to cover the welding position of stirrup B and avoid exposure and corrosion at the welding position of stirrup B.
[0012] Specifically, the galvanized wire mesh surface has through holes for inserting tie-in components.
[0013] By adopting the above technical solution, when the galvanized wire mesh is fixed to the outside of the mold column, the tie member is passed through the through hole opened on the surface of the galvanized wire mesh, so that one end of the tie member is fixed to the main steel bar, thereby improving the stability of the galvanized wire mesh fixing.
[0014] Specifically, the inner dimensions of the through hole match the outer dimensions of the tie member.
[0015] By adopting the above technical solution, when the tie member enters the through hole opened on the surface of the galvanized wire mesh, the size of the through hole matches the outside of the tie member, making it easy for the tie member to pass through the galvanized wire mesh.
[0016] The beneficial effects of this utility model are:
[0017] (1) The present invention describes a quick-cast, non-removable formwork column. The galvanized wire mesh is fixed to one side of the formwork column, and then the galvanized wire mesh is fixed more stably using tie rods. Then the other three sides of the formwork column are poured, so that the poured concrete can be fully vibrated, reducing the pouring time and increasing the density of the pouring.
[0018] (2) The quick-cast, non-removable formwork column described in this utility model has the following characteristics: after the galvanized wire mesh is fixed to the outside of the formwork column, the steel wire mesh inside the galvanized wire mesh increases the strength of the galvanized wire mesh. At the same time, galvanized steel mesh is welded to the four external corners of the formwork column, which increases the connection strength of the formwork column and thus prevents the formwork column from deforming during casting.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] To ensure that the poured concrete is fully vibrated, as one embodiment of this utility model, such as... Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a quick-cast, formwork-free shell column, comprising a main reinforcing bar 3, a strength-enhancing stirrup A1 welded to one side of the main reinforcing bar 3, a strength-enhancing stirrup B4 welded to the outside of the stirrup A1, a galvanized mesh 8 for end-sealing treatment welded to the outside of the main reinforcing bar 3, a tie member 7 for fixing and stabilizing the galvanized mesh 8 provided on the outside of the galvanized mesh 8, a steel wire mesh 9 for enhancing the strength of the galvanized mesh 8 welded to the inside of the galvanized mesh 8, and a galvanized steel mesh 5 for enhancing the connection strength welded to the outside of the main reinforcing bar 3.
[0026] When using it, first fix the galvanized wire mesh 8 to one side of the formwork column, and then use the tie piece 7 to make the galvanized wire mesh 8 more stable. Then pour the concrete on the other three sides of the formwork column so that the poured concrete can be fully vibrated, reducing the pouring time and increasing the density of the pouring.
[0027] After the galvanized wire mesh 8 is fixed to the outside of the mold column, the steel wire mesh 9 inside the galvanized wire mesh 8 increases the strength of the galvanized wire mesh 8. At the same time, galvanized steel mesh 5 is welded to the four external corners of the mold column, which increases the connection strength of the mold column and thus prevents the mold column from deforming during the pouring process.
[0028] To prevent the galvanized steel mesh 5 from bending and deforming, for example, such as Figure 1 , Figure 2 and Figure 3As shown, the present invention also includes reinforcing ribs 10 welded to the inner side of the galvanized steel mesh 5 to improve the strength of the galvanized steel mesh 5.
[0029] When in use, after the galvanized steel mesh 5 is fixed to the external corner of the mold column, the reinforcing ribs 10 welded inside the galvanized steel mesh 5 increase the strength of the galvanized steel mesh 5 and prevent the galvanized steel mesh 5 from bending and deforming.
[0030] To prevent exposed corrosion at the welding location of stirrup B4, for example, such as Figure 1 As shown, the present invention also includes a pad 2 that covers the weld joint when the stirrup B4 is sleeved on the outside.
[0031] When in use, after stirrup B4 is connected to stirrup A1, spacer 2 is placed on the outside of stirrup B4, and then spacer 2 is moved to the position where stirrup B4 is connected, so as to cover the welding position of stirrup B4 and avoid exposure and corrosion of the welding position of stirrup B4.
[0032] To improve the stability of the galvanized wire mesh 8, for example, such as Figure 1 As shown, the present invention also includes a through hole 6 on the surface of the galvanized wire mesh 8 for inserting the tie member 7.
[0033] When in use, when the galvanized wire mesh 8 is fixed to the outside of the mold column, the tie piece 7 is passed through the through hole 6 opened on the surface of the galvanized wire mesh 8, so that one end of the tie piece 7 is fixed to the main steel bar 3, thereby improving the stability of the galvanized wire mesh 8.
[0034] To facilitate the passage of the tie member 7 through the galvanized wire mesh 8, for example, such as Figure 1 As shown, the present invention also includes a through hole 6 whose inner dimensions match the outer dimensions of the tie member 7.
[0035] When in use, when the tie member 7 enters the through hole 6 on the surface of the galvanized wire mesh 8, the size of the through hole 6 matches the outside of the tie member 7, making it easy for the tie member 7 to pass through the galvanized wire mesh 8.
[0036] When using this utility model, first fix the galvanized wire mesh 8 to one side of the mold column, and then use the tie piece 7 to make the galvanized wire mesh 8 more stable. Then pour the concrete on the other three sides of the mold column so that the poured concrete can be fully vibrated, reducing the pouring time and increasing the density of the pouring.
[0037] After the galvanized wire mesh 8 is fixed to the outside of the mold column, the steel wire mesh 9 inside the galvanized wire mesh 8 increases the strength of the galvanized wire mesh 8. At the same time, galvanized steel mesh 5 is welded to the four external corners of the mold column, which increases the connection strength of the mold column and thus prevents the mold column from deforming during the pouring process.
[0038] After the galvanized steel mesh 5 is fixed to the external corner of the mold column, the reinforcing ribs 10 welded inside the galvanized steel mesh 5 increase the strength of the galvanized steel mesh 5 and prevent the galvanized steel mesh 5 from bending and deforming.
[0039] After stirrup B4 is connected to stirrup A1, spacer 2 is placed on the outside of stirrup B4, and then spacer 2 is moved to the position where stirrup B4 is connected, so as to cover the welding position of stirrup B4 and avoid exposure and corrosion at the welding position of stirrup B4.
[0040] When the galvanized wire mesh 8 is fixed to the outside of the mold column, the tie piece 7 is passed through the through hole 6 opened on the surface of the galvanized wire mesh 8, so that one end of the tie piece 7 is fixed to the main steel bar 3, thereby improving the stability of the galvanized wire mesh 8.
[0041] When the tie member 7 enters the through hole 6 on the surface of the galvanized wire mesh 8, the size of the through hole 6 matches the outside of the tie member 7, making it easy for the tie member 7 to pass through the galvanized wire mesh 8.
