Description

Technical Field

[0001] This utility model relates to the field of building tools technology, specifically a wall hole support device. Background Technology

[0002] In existing masonry building renovation projects, especially in the restoration of historical buildings, it is often necessary to chisel openings in a large number of old blue brick masonry walls to add doors and windows or replace damaged blocks, thereby strengthening the wall structure and updating its functions. Such renovations require temporary support for the wall above the new openings. Because masonry materials have low tensile and shear strength, openings will disrupt the original load transfer path, resulting in a weak area above the opening, similar to a "lintel." Without effective support, this can easily lead to instability and collapse of the masonry structure.

[0003] Currently, the mainstream support method involves laying horizontal steel plates at the top and bottom of the opening, with multiple channel steels evenly arranged between them as vertical supports. However, due to the complex damage to the bricks at the openings of ancient buildings and the diverse sizes of the openings required, the channel steel must be measured and cut on-site according to the height needed for each opening. This results in low construction efficiency, significant difficulty in controlling the cutting accuracy, and substantial waste as the channel steel is difficult to reuse after dismantling due to length differences. Although existing height-adjustable devices can accommodate openings of different heights, they still cannot solve the multi-point coordinated support needs of openings of different lengths. Furthermore, ancient building restoration projects are often extremely large-scale, and existing devices lack adaptability and cannot be reused. With the increasing requirements for green construction in public building renovation projects, the high waste and low adaptability of existing support methods are no longer sufficient to meet the needs of modern engineering.

[0004] Therefore, there is an urgent need for a wall opening support device with adjustable height, expandable length, and reusability to ensure the safety and economy of masonry wall opening construction. Utility Model Content

[0005] The purpose of this utility model is to provide a wall hole support device to solve the problems mentioned in the background art, so as to achieve the purpose of providing support by flexibly adjusting according to the height and length of the wall hole, and the device can be reused.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wall hole support device, comprising: At least one support component, the support component comprising: Base plate; A support rod is vertically fixed to the base plate, and the top of the support rod is a threaded section. An adjusting sleeve is threadedly connected to the threaded section of the support rod and configured to move up and down along the length of the support rod; A pressure-bearing sleeve is installed at the top of the adjusting sleeve to support the top of the wall opening.

[0007] As a further embodiment of this utility model: in order to increase the top bearing area of ​​the support component and avoid excessive pressure at a single point, a support plate is also included horizontally disposed on the top of the bearing sleeve, and the size of the support plate is configured to be disposed on the top of multiple support components.

[0008] As a further embodiment of this invention: to ensure that the multiple support components are located on the same horizontal line and to prevent a single support component from becoming unstable or tilting under stress, a connecting component for connecting the multiple support components is also included. The connecting component includes a connecting portion disposed on the support rod and a connecting rod connecting the multiple connecting portions. The multiple support components are arranged at intervals along the length of the opening and connected as a whole by the connecting rod.

[0009] As a further embodiment of this utility model: in order to provide stable support for the connecting rod and facilitate quick installation and disassembly of the connecting rod, the connecting part is a support rod that is obliquely upward fixed in the middle of the support rod.

[0010] As a further embodiment of this utility model: to facilitate the provision of support when laying bricks or filling concrete between multiple support components, the support component further includes a support side plate that is vertically fixed to the base plate, and the surface of the support side plate is perpendicular to the wall surface.

[0011] As a further embodiment of this utility model: to improve the structural strength and load-bearing capacity of the support assembly, the support assembly further includes a reinforcing plate fixedly connected between the base plate and the bottom of the support rod.

[0012] As a further embodiment of this utility model: in order to balance structural strength and the lightweight and economy of the supporting components, the reinforcing plate is a triangular steel plate.

[0013] As a further embodiment of this utility model: in order to increase the contact area between the support component and the top of the wall opening or the support plate, reduce the local stress at the contact point and make the load transfer smoother, the pressure-bearing sleeve is funnel-shaped, and its top opening radius is larger than its bottom opening radius.

[0014] As a further embodiment of this utility model: to ensure that the adjusting sleeve has sufficient stroke for height adjustment and that the adjusting sleeve can stably lift the pressure-bearing sleeve, the axial length of the adjusting sleeve is less than the threaded section length of the support rod, and the outer diameter is greater than the outer diameter of the pressure-bearing sleeve.

[0015] As a further embodiment of this utility model: to ensure that the support component is subjected to balanced forces and to avoid eccentric forces, the base plate is a rectangular steel plate, and the bottom end of the support rod is located at the geometric center of the base plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model features a novel structure. The adjusting sleeve can be raised and lowered on the support rod by rotation, thereby adjusting the height of the pressure-bearing sleeve to support the top of the wall opening. Furthermore, the appropriate number of support components can be flexibly selected according to the actual length of the opening to support openings of different lengths. The connecting components ensure that multiple support components are aligned in a straight line, guaranteeing a balanced and stable supporting force on the entire wall opening and preventing instability of a single support component under stress. The supporting side plates provide temporary lateral support for the newly constructed wall (brick masonry or concrete) built segment by segment between multiple support components within the opening. Once the newly constructed wall reaches sufficient strength, the corresponding support components can be removed, enabling the recycling and reuse of support components, improving construction efficiency and reducing costs.

They are only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application.

[0021] Please see Figure 1-8 In this embodiment of the utility model, a wall opening support device includes a support component 1. The support component 1 is set to at least one, and the number of support components 1 can be flexibly selected according to the actual size of the wall opening.

[0022] refer to Figure 1 The support assembly 1 includes a base plate 11, which is a rectangular steel plate. A support rod 12 is vertically welded to the geometric center of the upper surface of the base plate 11, ensuring balanced and stable force distribution on the support device and avoiding the risk of instability caused by eccentric force. A reinforcing plate 16 is welded between the base plate 11 and the bottom of the support rod 12. In this embodiment, the reinforcing plate 16 is specifically configured as two right-angled triangular steel plates located on both sides of the bottom of the support rod 12. The two right-angled sides of the triangular steel plates are fully welded to the base plate 11 and the support rod 12 on both sides, making the support rod 12 more stable on the base plate 11.

[0023] refer to Figure 2The top end of the support rod 12 is a threaded section. The support rod 12 is made of steel bar with a diameter of 28-32 mm. In this embodiment, the support rod 12 is specifically made of HRB400 steel bar with a diameter of 32 mm. The top of the support rod 12 is formed by rib stripping and rolling. The threaded section of the support rod 12 is threadedly connected to an adjusting sleeve 13. A pressure-bearing sleeve 14 is movably installed at the top end of the adjusting sleeve 13. The adjusting sleeve 13 is sleeved on the support rod 12 and moves up and down along the length of the support rod 12 by rotation, so that the pressure-bearing sleeve 14 placed at the top end of the adjusting sleeve 13 is tightened and supports the top of the wall opening by adjustment.

[0024] refer to Figure 1 and Figure 4 The pressure-bearing sleeve 14 is specifically funnel-shaped, with its top opening radius larger than its bottom opening radius. This increases the contact area between the top of the pressure-bearing sleeve 14 and the top of the wall opening, resulting in a more uniform supporting force from the support assembly 1. The bottom inner diameter of the pressure-bearing sleeve 14 is slightly larger than the diameter of the support rod 12, allowing the bottom of the pressure-bearing sleeve 14 to fit onto the outer wall of the support rod 12. The outer diameter of the adjusting sleeve 13 is larger than the outer diameter of the pressure-bearing sleeve 14, providing stable support for the pressure-bearing sleeve 14. The axial length of the adjusting sleeve 13 is less than the length of the threaded section of the support rod 1, ensuring that the adjusting sleeve 13 has sufficient stroke for height adjustment.

[0025] refer to Figure 5 and Figure 6 When the wall opening is small, such as Figure 5 As shown, only one support component 1 is needed to support the wall opening. When the wall opening is large, an appropriate number of support components 1 need to be selected according to the opening size, such as... Figure 6 As shown, when the wall opening size is 1200*340 mm, three support components 1 are sufficient to support the wall opening. Support component 1 also includes a support plate 2, which is horizontally positioned on top of the pressure-bearing sleeve 14 to increase the top pressure-bearing area of ​​the support component 1 and prevent excessive pressure on a single point in the wall opening. The number of support plates 2 can be configured to correspond one-to-one with the number of support components 1, or it can be configured such that one of the plates can be positioned on top of multiple support components 1 simultaneously. Figure 6 As shown, a support plate 2 is provided on the top of multiple support components 1.

[0026] refer to Figure 1 and Figure 6The support assembly 1 also includes a connecting assembly 3 for connecting multiple support assemblies 1. The connecting assembly 3 includes a connecting rod 32 and a connecting portion 31 welded to the support rod 12. Specifically, the connecting portions 31 are two symmetrically welded on both sides of the support rod 12. In this embodiment, the connecting portion 31 is specifically a support rod welded obliquely upward to the middle of the support rod 12, forming a V-shaped groove for placing the connecting rod 32. Both the support rod and the connecting rod 32 are made of reinforcing steel. Figure 6 As shown, multiple support components 1 are arranged at intervals along the length of the opening. The connecting rod 32 is placed in the V-groove between the support rod and the support rod 12, connecting the multiple support components 1 into one unit, so that the multiple support components 1 are located on the same straight line in the opening, ensuring the stability of a single support component 1 under stress.

[0027] refer to Figure 7 and Figure 8 The support assembly 1 also includes a support side plate 15 vertically fixed to the base plate 11. The base plate 11 has slots on both sides of its upper surface, with the axial direction of the slots perpendicular to the wall. The bottom of the support side plate 15 is embedded in the slot, and the surface of the support side plate 15 is perpendicular to the wall, allowing the support side plate 15 to be positioned between two adjacent support assemblies 1 (e.g., ...). Figure 7 The newly laid bricks or filled concrete in area A (as shown) provide temporary lateral support, facilitating the subsequent removal of the corresponding support components 1, ultimately completing the repair of the entire opening. Figure 8 As shown. At the same time, the connecting rod 32 can be cut according to the distance from the supporting side plate 15 to the side wall of the opening, so that one end of the connecting rod 32 abuts against the side wall of the opening and the other end abuts against the supporting side plate 15, providing auxiliary support for the supporting side plate 15. In this embodiment, the supporting side plate 15 is specifically a steel plate.

[0028] This utility model has a novel structure and stable operation. In use, after completing the opening work in the wall to be repaired, a suitable number of support components 1 are selected according to the actual size of the opening. The support components 1 are then spaced apart along the length of the opening. The connecting rod 32 is placed between the connecting part 31 and the support rod 12, ensuring that multiple support components 1 are aligned. The adjusting sleeve 13 is rotated to adjust the height of the pressure-bearing sleeve 14 on the support rod 12. When the pressure-bearing sleeves 14 of multiple support components 1 are close to the top of the opening, the support plate 2 is placed on top of the pressure-bearing sleeves 14 of multiple support components 1. Then, the multiple adjusting sleeves 13 are rotated and adjusted until the support plate 2 is pressed tightly against the top of the opening by the pressure-bearing sleeves 14. Then, when repairing the opening, the area that needs to be repaired first (such as...) Figure 7In area A shown, the two support components 1 on both sides are fitted into the corresponding support side plates 15 in the slots of the base plate 11. Then, the length of the connecting rod 32 is cut according to the distance from the support side plate 15 to the side wall of the opening, so that the connecting rod 32 can support the support side plate 15 and the side wall of the opening. Then, a wooden template is placed between the two corresponding support side plates 15, so that the support side plates 15 provide support for the wooden template. Then, bricklaying or concrete filling is carried out in the area that needs to be repaired first. After the newly built wall in this area reaches sufficient strength, the support component 1 on one side of the area is removed and can be used for the repair of other wall openings, realizing the recycling of the support component 1. Then, the above local repair work is repeated for the openings in turn until the repaired wall is sufficiently supported by the newly built wall. At this time, all support components 1 are removed, and the remaining opening repair work is completed. Figure 8 As shown, all support components 1 can then be used for the repair of other masonry walls.
