Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a temporary bottom support device for aluminum formwork construction. Background Art

[0002] Aluminum alloy formwork, also known as aluminum alloy formwork for concrete engineering, is a new generation of formwork systems, following plywood formwork, combined steel formwork systems, steel-framed wood (bamboo) plywood systems, large formwork systems, and early-dismantle formwork systems. Made primarily of aluminum alloy profiles, aluminum alloy formwork is manufactured through machining and welding processes to create a formwork suitable for concrete engineering. The design and construction application of aluminum alloy formwork represents a technological innovation in concrete engineering formwork. Aluminum formwork typically requires temporary support equipment for secure fixation during use. Because the bottom of aluminum formwork bears greater pressure during concrete pouring, support and fixation of the bottom of the aluminum formwork are even more crucial. Furthermore, load-bearing columns must withstand greater forces, necessitating stricter pouring requirements. Therefore, temporary support equipment for the bottom of prefabricated aluminum formwork for load-bearing columns is particularly important.

[0003] However, the existing temporary support equipment for aluminum formwork has the following problems: 1. The fixing effect of the bottom of the temporary support equipment commonly used for aluminum formwork is not good enough, resulting in concrete leakage at the corners during pouring.

[0004] 2. The temporary bottom support equipment used in conventional aluminum formwork construction is inconvenient to adjust the lateral position and support angle during use, and is therefore applicable to limited work scenarios. Summary of the Invention

[0005] 1. Technical Problems to be Solved: The present invention provides a temporary bottom support device for the construction of assembled aluminum formwork, which can solve the problems pointed out in the above background technology.

[0006] 2. Technical solution: In order to achieve the above purpose, the present invention adopts the following technical solution: a temporary bottom support equipment for the construction of prefabricated aluminum formwork, including four groups of support mechanisms, clamping mechanisms, support rods and connecting mechanisms. The four groups of support mechanisms are arranged in a rectangular shape, and each group includes two support mechanisms. A clamping mechanism is installed behind the support mechanism. The two support mechanisms in the same group are connected by a support rod, and the ends of adjacent support rods are connected and reinforced by a connecting mechanism.

[0007] The support mechanism includes a side support plate, a bottom support plate and an adjustable threaded rod. A threaded ear seat is installed on each side of the left and right sides of the bottom support plate, and the threads inside the threaded ear seats on the two bottom support plates in the same group have opposite rotation directions. A through-hole ear seat is installed on each side of the left and right sides of the side support plate. A No. 1 through-hole is opened in the middle of the side support plate, and three No. 2 through-holes are vertically arranged in the middle of the bottom support plate.

[0008] The adjustable threaded rod includes a threaded cap, a threaded rod and a rotating support. The upper end of the threaded cap is threadedly matched with the threaded rod, the threaded rod and the side support plate are hinged, the lower end of the threaded cap is rotatably connected to the rotating support, and the rotating support and the bottom support plate are hinged.

[0009] As a preferred technical solution of the present invention, the clamping mechanism includes an active rod, a driven rod, an upper clamping block and a lower clamping block. The rear end of the active rod rotates through the No. 1 through hole in the middle of the side support plate and is connected to the driven rod located on the rear side of the side support plate. The rear end of the active rod is connected to the active bevel gear and meshes with the driven bevel gear installed in the middle of the driven rod. The driven rod is rotatably installed on the rear side of the side support plate. The upper and lower ends of the driven rod are respectively provided with threads with opposite rotation directions. The upper clamping block and the lower clamping block are respectively installed at the upper and lower ends of the driven rod; a threaded through hole is provided in the middle of the upper clamping block and the lower clamping block, and the rotation direction of the threaded through hole matches the threads at the upper and lower ends of the driven rod.

[0010] As a preferred technical solution of the present invention, the support rod includes an upper support rod and a lower support rod. The lower support rod is a screw rod with left-right symmetrical threads. The lower support rod is connected to the threaded ear seat through threaded cooperation. The upper support rod slides through the through-hole ear seat, and a circular ring is installed on the end face of the upper support rod.

[0011] As a preferred technical solution of the present invention, the connecting mechanism includes two winding ropes, a fixed base and a fixed threaded rod. A chain buckle is installed at one end of the winding rope, and the chain buckle is connected to the ring. The other end of the winding rope is fixed on the fixed threaded rod. There are four No. 3 through holes at the bottom of the fixed base for fixing to the ground through bolts. The upper end of the fixed base is matched with the fixed threaded rod through a threaded cap.

[0012] As a preferred technical solution of the present invention, the upper surface of the upper clamping block and the lower surface of the lower clamping block are both serrated, and a layer of rubber is installed on the surface.

[0013] As a preferred technical solution of the present invention, the front end of the active rod is in the shape of a hexagonal nut, the middle of the lower support rod is in the shape of a hexagonal nut and is smaller than the radius of the threaded columns at both ends, and the upper end of the fixed threaded rod is in the shape of a hexagonal nut, which is convenient for rotation by a wrench.

[0014] 3. Beneficial effects: 1. The support mechanism provided by the present invention can adjust the angle between the two side support plates and the bottom support plate by rotating the threaded cap when facing the working ground or aluminum formwork at different angles, ensuring that the side support plates and the aluminum formwork as well as the bottom support plate and the ground fit better, thereby achieving better supporting effect.

[0015] 2. When the active rod of the clamping mechanism provided by the present invention rotates, the driven rod is driven to rotate through the bevel gear. When the driven rod rotates, the upper and lower threads will cause the upper clamping block and the lower clamping block to move in opposite directions. The reverse movement of the upper clamping block and the lower clamping block enables them to fully clamp with the protrusions on the aluminum template, which facilitates better clamping of the aluminum template. The upper surface of the upper clamping block and the lower surface of the lower clamping block are both serrated, and a layer of rubber is installed on the surface, which further improves the clamping effect.

[0016] 3. The lower support rod provided by the present invention can adjust the distance between the support mechanisms by rotation, so that the aluminum formwork can be better supported. At the same time, the upper support rod and the lower support rod work together to enhance the supporting effect of the support mechanism.

[0017] 4. The connecting mechanism provided by the present invention is connected through the winding rope on the threaded column and the circular ring on the adjacent upper support rod. When the threaded column rotates, the winding rope will be tightened, thereby tightening the support mechanism, so that the four support mechanisms are connected as a whole, thereby better fixing the aluminum template at the corner.

DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0027] The following describes a temporary bottom support device for construction of assembled aluminum formwork according to an embodiment of the present invention with reference to the accompanying drawings.

[0028] See Figure 1 A temporary bottom support device for the construction of assembled aluminum formwork includes four groups of support mechanisms 1, a clamping mechanism 2, a support rod 3 and a connecting mechanism 4.

[0029] See Figure 1 and Figure 2 Each group of support mechanisms 1 is two in number, and the support mechanism 1 includes a side support plate 11, a bottom support plate 12 and an adjustable threaded rod 13. A threaded ear seat 111 is installed on each side of the left and right sides of the bottom support plate 12, and the internal threads of the threaded ear seats 111 on the two bottom support plates 12 in the same group are rotated in opposite directions. A through-hole ear seat 112 is installed on each side of the side support plate 11, a No. 1 through-hole is opened in the middle of the side support plate 11, and three No. 2 through-holes are vertically arranged in the middle of the bottom support plate 12 for fixing to the ground.

[0030] See Figure 2 The adjustable threaded rod 13 includes a threaded cap 131, a threaded rod 132, and a rotating support 133. The upper end of the threaded cap 131 is threadedly engaged with the threaded rod 132, the threaded rod 132 is hinged to the side support plate 11, and the lower end of the threaded cap 131 is rotatably connected to the rotating support 133, and the rotating support 133 is hinged to the bottom support plate 12. The threaded cap 131 can be rotated by the rotating support 133, thereby screwing together with the threaded rod 132 to adjust the distance between the threaded cap 131 and the threaded rod 132. The angle between the side support plate 11 and the bottom support plate 12 can be adjusted by adjusting the distance between the threaded cap 131 and the threaded rod 132, so that the side support plate 11 and the aluminum template or the bottom support plate 12 and the ground are more closely fitted, thereby achieving a better support effect.

[0031] It should be noted that in order to improve the synchronization of the rotation of multiple threaded caps 131, a pulley (not shown in the figure) can be installed on the outer wall of the threaded cap 131, and the four pulleys in the two support mechanisms 1 in the same group are connected by a transmission belt, so that only one threaded cap 131 needs to be rotated to drive the rotation of the other three threaded caps 131 in the two support mechanisms 1 in the same group.

[0032] See Figure 3The clamping mechanism 2 includes an active rod 21, a driven rod 22, an upper clamping block 23, and a lower clamping block 24. The rear end of the active rod 21 rotates through the No. 1 through-hole in the middle of the side support plate 11. The front end of the active rod 21 is in the shape of a hexagonal nut, which is convenient for rotation with a wrench. The rear end of the active rod 21 is connected to the active bevel gear 211 and meshes with the driven bevel gear 212 installed in the middle of the driven rod 22. The driven rod 22 is rotatably installed on the rear side of the side support plate 11. The upper and lower ends of the driven rod 22 are respectively provided with threads with opposite rotation directions. The upper clamping block 23 and the lower clamping block 24 are respectively installed at the upper and lower ends of the driven rod 22, and a threaded through-hole is provided in the middle of the upper clamping block 23 and the lower clamping block 24. The rotation direction of the threaded through-hole matches the threads at the upper and lower ends of the driven rod 22. The upper surface of the upper clamping block 23 and the lower surface of the lower clamping block 24 are both serrated, and a layer of rubber is installed on the surface to facilitate better clamping of the aluminum template. By turning the wrench, the active rod 21 of the clamping mechanism 2 rotates, which in turn rotates the driven rod 22 through the cooperation of the active bevel gear 211 and the driven bevel gear 212. As the driven rod 22 rotates, the upper and lower clamping blocks 23 and 24 move in opposite directions through the reversed upward and downward threads. The reverse movement of the upper and lower clamping blocks 23 and 24 allows them to fit tightly against the protrusions on the side panels of the aluminum formwork, thereby improving the support effect of the support mechanism 1.

[0033] See Figure 4 The support rod 3 includes an upper support rod 31 and a lower support rod 32. The lower support rod 32 is a screw with bilaterally symmetrical threads. The lower support rod 32 is connected to the threaded ear seat 111 through a threaded fit. The middle of the lower support rod 32 is in the shape of a hexagonal nut and has a smaller radius than the threaded columns 43 at both ends. The upper support rod 31 slides through the through-hole ear seat 112. The upper support rod 31 of an appropriate length can be selected according to actual needs. The end face of the upper support rod 31 is installed with a ring 311. The distance between the two support structures 2 in the same group can be adjusted by rotating the lower support rod 32. In this way, the aluminum template can be better supported according to its actual size. At the same time, the upper support rod 31 and the lower support rod 32 can strengthen the supporting effect of the support mechanism 1.

[0034] See Figure 5 The connection mechanism 4 includes two winding ropes 41, a fixed base 42, and a threaded post 43. A chain link 411 is attached to one end of the winding rope 41, which is connected to the ring 311. The other end of the winding rope 41 is fixed to the threaded post 43. The bottom of the fixed base 42 has four No. 3 through-holes for bolting to the ground. The upper end of the fixed base 42 is mated with a nut and the threaded post 43, which has a hexagonal nut at the top. The connection mechanism 4 is connected by the winding rope 41 on the threaded post 43 and the ring 311 on the adjacent upper support rod 31. When the threaded post 43 rotates, the winding rope 41 is tightened, thereby tightening the four sets of support mechanisms 1 and connecting them as a whole, better fixing the aluminum formwork at the corner.

[0035] Specific installation and use: Step 1: First, install the support mechanism 1 of each group on the lower support rod 32, and adjust the spacing of the support mechanism 1 by rotating the lower support rod 32 to reach a suitable position.

[0036] Step 2: Fix the bottom support plate 12 to the ground with bolts. Then adjust the length of the adjustable threaded rod 13 to control the angle between the side support plate 11 and the bottom support plate 12, so that the side support plate 11 fully fits the aluminum formwork to achieve better support effect.

[0037] Step 3: In order to further provide a better supporting effect, the upper clamping block 23 and the lower clamping block 24 are clamped to the protrusions on the side wall of the aluminum template by rotating the active rod 21 of the clamping mechanism 2.

[0038] Step 4: Connect adjacent upper support rods 31 through the winding rope 41 on the threaded column 43.

[0039] Step 5: Fix the fixed base 42 to the ground with bolts, then screw the threaded column 43 into the fixed base 42, and further tighten the threaded column 43 to make the winding rope 41 tighten the upper support rod 31, so that the four support mechanisms 1 are connected as a whole to better fix the aluminum formwork at the corner.
