Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a wall column formwork support and fixing device. Background Technology

[0002] Formwork engineering refers to the formwork used to shape freshly poured concrete, as well as the entire structural system that supports the formwork. The structural part that comes into contact with the concrete and controls its predetermined size, shape, and position is called the formwork, while the members, trusses, connectors, metal fittings, and temporary working bridges that support and fix the formwork constitute the support system.

[0003] When constructing building side walls, formwork supports are needed to fix the side wall formwork. In existing formwork support construction, bolts need to be pre-embedded at the base of the formwork support to fix it, making it difficult to adjust according to the formwork position. Chinese invention patent application number 202110993747.1, "Fixing Device for Side Wall Formwork and its Construction Method," discloses a method that "fixes the support to the ground using suction cups and adjusting frames, and supports and fixes the side wall formwork using the support and keel to prevent displacement, allowing for concrete pouring within the side wall formwork. After pouring, when dismantling the formwork, simply separate the suction cups from the ground to remove the support and side wall formwork, facilitating installation and dismantling, avoiding damage to the ground, and allowing for reuse and material saving."

[0004] However, since the bottom surface in building construction scenarios is usually uneven, it is difficult to provide the non-porous surface required for suction cups to work, except for specially manufacturing an adsorption flat surface. Therefore, its applicability is poor and it cannot quickly adapt to the installation needs of various uneven bottom surfaces. Summary of the Invention

[0005] The purpose of this invention is to provide a wall column formwork support and fixing device, which aims to solve the problems mentioned in the background art.

[0006] The present invention is implemented as follows: a wall column formwork support and fixing device includes a support plate, wherein the support plate is provided with a plurality of keels, and further includes:

[0007] The support part is provided in multiple sets. Each set of the support part includes two positioning mechanisms. The two positioning mechanisms in the same set are connected to each other by a telescopic connecting component. One of the positioning mechanisms is connected to the bottom of the support plate on the side away from the keel.

[0008] The positioning mechanism includes a mounting box. The mounting box, located away from the support plate, is connected to the upper side wall of the support plate via a diagonal brace. Two rotating shafts are symmetrically mounted inside the mounting box. Two helical gears are symmetrically arranged on the rotating shafts. A drive gear is mounted in the middle of the rotating shafts, and the drive gear is connected to the rotating shafts via a sliding key. A second rack is provided on one side of each helical gear. The second rack is slidably mounted in the mounting box in the vertical direction, and the helical gear meshes with the second rack. A first rack is also provided above the drive gear, and the first rack meshes with the drive gear. The first rack is slidably mounted in the mounting box in the horizontal direction. An adjustment component is also provided on the top of the mounting box for simultaneously driving the two first racks to move horizontally.

[0009] A support assembly is provided at the bottom of the mounting box, and the bottom of each of the second racks is connected to a set of support assemblies. The second racks support the mounting box by extending the corresponding support assemblies.

[0010] A further technical solution is that the support plate adopts a frame structure, which facilitates manufacturing, reduces its weight, and makes it easier to install and transport.

[0011] In a further technical solution, the connecting assembly includes a connecting rod and a telescopic rod. The connecting rod and the telescopic rod are respectively installed on two mounting boxes of the same set of support parts, and one end of the telescopic rod is slidably installed in the connecting rod. The telescopic rod is provided with multiple positioning holes along its length direction, and the connecting rod is provided with positioning bolts that cooperate with the positioning holes.

[0012] In a further technical solution, the support assembly includes a mounting sleeve installed on the bottom wall of the mounting box, a support rod slidably installed in the mounting sleeve along the vertical direction, and a return spring connected to the support rod is provided in the mounting sleeve. The bottom of the second rack penetrates the bottom wall of the mounting box and abuts against the top of the support rod. A base plate is connected to the bottom of the support rod, and the base plate is rotatably installed on the support rod.

[0013] A further technical solution is that a ball joint seat is provided at the top of the base plate, and a universal ball joint is provided at the bottom of the support rod. The universal ball joint is rotatably installed in the ball joint seat. Under the cooperation of the universal ball joint and the ball joint seat, the base plate can be adjusted in various directions around the support rod, thereby flexibly adapting to planes with different inclinations.

[0014] A further technical solution includes an adjustment assembly comprising a mounting frustum mounted on the top of the mounting box, an adjustment screw mounted on the mounting frustum, the adjustment screw penetrating the top wall of the mounting frustum and connected to the top wall of the mounting frustum by a threaded engagement, a connecting plate rotatably mounted on one end of the adjustment screw located inside the mounting frustum, two adjustment rods symmetrically arranged on the bottom surface of the connecting plate, the adjustment rods rotatably mounted on the bottom of the connecting plate, and the end of the adjustment rod away from the connecting plate rotatably mounted on a first rack.

[0015] A further technical solution is that a level is installed on the top wall of each of the mounting boxes, which allows operators to visually observe whether the mounting box is in a level state when leveling.

[0016] This invention provides a wall column formwork support and fixing device. In use, after the wall column formwork is installed, a support plate is installed on the outside of the formwork, ensuring that each joist is in close contact with the formwork. Then, the adjusting components on each positioning mechanism are adjusted accordingly. These adjusting components drive two first racks in the mounting box to move horizontally synchronously, with the two racks moving in opposite directions. The first racks drive a drive gear to rotate, which in turn drives a rotating shaft to rotate synchronously. The rotating shaft then drives two helical gears on it to rotate synchronously. During the rotation of the helical gears, the second rack moves downwards vertically, thereby pushing the support component to extend and bring it into contact with the bottom surface. For two second racks driven by the same shaft, when the support component driven by one second rack is in contact with the ground while the support component driven by the other second rack is not yet in contact with the ground, as the shaft continues to rotate, under the vertical limiting action of the already fixed second rack, the corresponding helical gear will push the shaft to move laterally, thereby driving the support component that is not yet fully fixed to the ground to continue moving, while ensuring that the length of the fixed support component remains unchanged. With the cooperation of multiple sets of support components, the mounting box is ultimately placed horizontally, thus achieving stable support for the support plate. Simultaneously, installing the diagonal brace between the support plate and the corresponding mounting box completes the support of the support plate, thereby effectively supporting and fixing the wall column formwork. This device is applicable to various ground environments in construction scenarios, is highly adaptable, simple to operate, convenient to install, and provides excellent support.

Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0026] As Figure 1-5 shown, a wall column formwork support and fixation device provided by an embodiment of the present invention includes a support plate 1, and a plurality of keels 11 are arranged on the support plate 1. It further includes:

[0027] A support part, multiple groups of the support part are provided, each group of the support part includes two positioning mechanisms 2, and the two positioning mechanisms 2 in the same group are connected to each other through a telescopic connection component 3, and one of the positioning mechanisms 2 is connected to the bottom of the side of the support plate 1 away from the keel 11;

[0028] The positioning mechanism 2 includes a mounting box 21. The mounting box 21, which is away from the support plate 1, is connected to the upper side wall of the support plate 1 via a diagonal brace 12. Two rotating shafts 22 are symmetrically installed inside the mounting box 21. Two helical gears 23 are symmetrically arranged on the rotating shafts 22. A drive gear 24 is installed in the middle of the rotating shafts 22, and the drive gear 24 is connected to the rotating shafts 22 via a sliding key. A second rack 26 is provided on one side of the helical gear 23. The second rack 26 is slidably installed in the mounting box 21 in the vertical direction, and the helical gear 23 meshes with the second rack 26. A first rack 25 is also provided above the drive gear 24, and the first rack 25 meshes with the drive gear 24. The first rack 25 is slidably installed in the mounting box 21 in the horizontal direction. An adjustment component 4 is also provided on the top of the mounting box 21 for simultaneously driving the two first racks 25 to move horizontally.

[0029] The support component 5 is disposed at the bottom of the mounting box 21, and the bottom of each of the second racks 26 is connected to a set of support components 5. The second racks 26 support the mounting box 21 by driving the corresponding support components 5 to extend.

[0030] In this embodiment of the invention, the mounting box 21 near the support plate 1 is connected to the support plate 1 by bolts, which facilitates the assembly and disassembly of the device and makes it easy to adapt to support plates 1 of different sizes. In use, after the wall column template is installed, the support plate 1 is installed on the outside of the wall column template, ensuring that each keel 11 is in close contact with the template. Then, the adjusting components 4 on each positioning mechanism 2 are adjusted accordingly. The adjusting components 4 can drive the two first racks 25 in the mounting box 21 to move horizontally synchronously, and the two first racks 25 move in opposite directions. The first racks 25 can drive the drive gear 24 to rotate, and the drive gear 24 drives the rotating shaft 22 to rotate synchronously. The rotating shaft 22 can drive the two helical gears 23 on it to rotate synchronously. During the rotation of the helical gears 23, the second rack 26 moves downwards in the vertical direction, thereby pushing the support component 5 to extend, so that the support component 5 contacts the bottom surface. For the two second racks 26 driven by the same rotating shaft 22, when the support component 5 driven by one second rack 26 is in contact with the ground, while the support component 5 driven by the other second rack 26 is not yet in contact with the ground, as the rotating shaft 22 continues to rotate, under the vertical limiting action of the already fixed second rack 26, the corresponding helical gear 23 will push the rotating shaft 22 to move laterally, thereby driving the support component 5 that is not yet fully fixed to the ground to continue moving, while ensuring that the length of the fixed support component 5 remains unchanged. With the cooperation of multiple sets of support components 5, the mounting box 21 is ultimately placed in a horizontal position, thus achieving stable support for the support plate 1. At the same time, the diagonal brace 12 is installed between the support plate 1 and the corresponding mounting box 21, thus completing the support of the support plate 1, thereby effectively supporting and fixing the wall column formwork.

[0031] like Figure 1 and 2 As shown, in a preferred embodiment of the present invention, the connecting component 3 includes a connecting rod 31 and a telescopic rod 32. The connecting rod 31 and the telescopic rod 32 are respectively installed on two mounting boxes 21 of the same set of support parts, and one end of the telescopic rod 32 is slidably installed in the connecting rod 31. The telescopic rod 32 is provided with a plurality of positioning holes 33 along its length direction, and the connecting rod 31 is provided with positioning bolts 34 that cooperate with the positioning holes 33.

[0032] In this embodiment of the invention, the length of the connecting component 3 can be adjusted according to the usage requirements. Specifically, simply pull the telescopic rod 32 along the connecting rod 31. When the telescopic rod 32 moves to the designated position, insert the positioning bolt 34 into the corresponding positioning hole 33 to fix the telescopic rod 32. This allows for adjustment of the distance between the two mounting boxes 21 of the same set of support parts, thereby adapting to different usage requirements.

[0033] like Figure 3and 4 As shown, in a preferred embodiment of the present invention, the adjustment assembly 4 includes a mounting frustum 41 mounted on the top of the mounting box 21. An adjustment screw 42 is mounted on the mounting frustum 41. The adjustment screw 42 passes through the top wall of the mounting frustum 41 and is connected to the top wall of the mounting frustum 41 by a threaded engagement. A connecting plate 43 is rotatably mounted on one end of the adjustment screw 42 located inside the mounting frustum 41. Two adjustment rods 44 are symmetrically arranged on the bottom surface of the connecting plate 43. The adjustment rods 44 are rotatably mounted on the bottom of the connecting plate 43, and the end of the adjustment rod 44 away from the connecting plate 43 is rotatably mounted on a first rack 25.

[0034] In this embodiment of the invention, during use, simply rotating the adjusting screw 42 is sufficient. The adjusting screw 42 can move vertically along its axial direction, which can drive the connecting plate 43 to move synchronously downward. The connecting plate 43 can drive the adjusting rod 44 to move synchronously, and the adjusting rod 44 can drive the corresponding first rack 25 to move linearly horizontally inside the mounting box 21, thereby achieving synchronous adjustment of the two first racks 25 in the same mounting box 21.

[0035] like Figure 4 and 6 As shown, in a preferred embodiment of the present invention, the support assembly 5 includes a mounting sleeve 51 mounted on the bottom wall of the mounting box 21. A support rod 52 is slidably mounted in the mounting sleeve 51 in the vertical direction, and a return spring 54 connected to the support rod 52 is provided in the mounting sleeve 51. The bottom of the second rack 26 penetrates the bottom wall of the mounting box 21 and abuts against the top of the support rod 52. A base plate 53 is connected to the bottom of the support rod 52, and the base plate 53 is rotatably mounted on the support rod 52.

[0036] In this embodiment of the invention, during use, as the second rack 26 moves downward, the second rack 26 can push the support rod 52 to move downward synchronously, thereby pushing the base plate 53 to contact and press against the bottom surface through the support rod 52, thereby achieving the positioning and fixing of the device.

[0037] like Figure 4 and 6 As shown, in a preferred embodiment of the present invention, a ball joint seat 56 is provided on the top of the base plate 53, and a universal ball joint 55 is provided on the bottom of the support rod 52. The universal ball joint 55 is rotatably installed in the ball joint seat 56. Under the cooperative action of the universal ball joint 55 and the ball joint seat 56, the base plate 53 can be adjusted in various directions around the support rod 52, thereby flexibly adapting to planes with different inclinations.

[0038] like Figure 1As shown, in a preferred embodiment of the present invention, the support plate 1 adopts a frame structure, which facilitates production, reduces its weight, and facilitates installation and transportation.

[0039] As a preferred embodiment of the present invention, a level is installed on the top wall of each of the mounting boxes 21, which allows the operator to visually observe whether the mounting box 21 is in a horizontal state when leveling.

[0040] Working Principle: During use, after the wall column formwork is installed, the support plate 1 is installed on the outside of the wall column formwork, ensuring that each keel 11 is in close contact with the formwork. Then, the adjusting components 4 on each positioning mechanism 2 are adjusted accordingly. Specifically, simply rotating the adjusting screw 42 allows the adjusting screw 42 to move vertically along its axis. The adjusting screw 42 drives the connecting plate 43 to move downwards synchronously, which in turn drives the adjusting rod 44 to move synchronously. The adjusting rod 44 then drives the corresponding first rack 25 to move linearly horizontally inside the mounting box 21, thus achieving synchronous adjustment of the two first racks 25 in the same mounting box 21. The two first racks 25 move in opposite directions. The first rack 25 drives the drive gear 24 to rotate, which in turn drives the rotating shaft 22 to rotate synchronously. The rotating shaft 22 then drives the two helical gears 23 on it to rotate synchronously. During the rotation of the helical gears 23, the second rack 26 moves downwards vertically, pushing the support component 5 to extend, thus bringing the support component 5 into contact with the bottom surface. For the two second racks 26 driven by the same rotating shaft 22, when the support component 5 driven by one second rack 26 is in contact with the ground, while the support component 5 driven by the other second rack 26 is not yet in contact with the ground, as the rotating shaft 22 continues to rotate, under the vertical limiting action of the already fixed second rack 26, the corresponding helical gear 23 will push the rotating shaft 22 to move laterally, thereby driving the support component 5 that is not yet fully fixed to the ground to continue moving, while ensuring that the length of the fixed support component 5 remains unchanged. With the cooperation of multiple sets of support components 5, the mounting box 21 is ultimately placed in a horizontal position, thus achieving stable support for the support plate 1. At the same time, the diagonal brace 12 is installed between the support plate 1 and the corresponding mounting box 21, thus completing the support of the support plate 1, thereby effectively supporting and fixing the wall column formwork.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
