Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a lintel device for openings in brick walls. Background Art

[0002] With the rapid development of social modernization, earth-shaking changes have taken place in the urban landscape of our country. Nowadays, many old houses have not reached the service life and are still in a usable state. However, for the current urban landscape, production, and living needs, the internal structural configuration and functional zoning of some rooms have become relatively backward, and the houses need to be demolished or renovated.

[0003] Considering that the time and cost required for demolition and reconstruction are relatively large, and the houses have not reached the service life requirements, demolition and reconstruction will cause unnecessary waste. Therefore, strengthening and transforming the original structure has become the preferred solution. During the transformation process, there are some existing brick walls that need to be opened to adjust the spatial layout. Before opening a conventional small-width opening, a steel plate beam can be not set above the opening as a lintel to bear the load transmitted from the upper wall. However, for a relatively wide and large opening, the steel plate beam is difficult to bear the load transmitted from the upper wall. But if all the upper wall of the opening is demolished, it will cause greater damage to the existing structure, and the engineering quantity is large, the construction time is long, and the potential safety hazard is large. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a lintel device for openings in brick walls, which can effectively improve the construction efficiency of wall transformation and reduce potential safety hazards.

[0005] The utility model is realized as follows: A lintel device for openings in brick walls includes a lintel opening arranged above an opening to be formed in a brick wall. A lintel is embedded and installed inside the lintel opening. The inside of the lintel is a hollow structure, and a plurality of C-shaped steel braces are uniformly arranged inside the lintel. Both the upper and lower ends of the C-shaped steel braces are fixedly installed with the upper and lower ends of the lintel. And one side of the C-shaped steel brace is provided with an opening. The top of the opening is provided with a groove located at the inner top of the C-shaped steel brace. The bottom of the opening is provided with a convex block located at the inner bottom of the C-shaped steel brace. A sealing member is fixedly installed inside the C-shaped steel brace. The top of the sealing member is provided with a protrusion matching the groove. The bottom of the sealing member is provided with a notch matching the convex block. The sealing member is fixed on the C-shaped steel brace by the groove being engaged with the protrusion and the convex block being engaged with the notch.

[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] See also Figure 1 and Figure 2, the present utility model provides a lintel device for an opening in a brick wall, including a lintel opening 3 arranged above an opening 2 to be formed in a brick wall 1. A lintel 4 is embedded and installed inside the lintel opening 3. The inside of the lintel 4 is a hollow structure, and a plurality of C-shaped steel braces 5 are uniformly arranged inside the lintel 4. Both the upper and lower ends of the C-shaped steel brace 5 are fixedly installed with the upper and lower ends of the lintel 4. One side of the C-shaped steel brace 5 is provided with an opening 6. The top of the opening 6 is provided with a groove 7 located at the inner top of the C-shaped steel brace 5. The bottom of the opening 6 is provided with a convex block 8 located at the inner top of the C-shaped steel brace 5. A sealing member 9 is fixedly installed inside the C-shaped steel brace 5. The top of the sealing member 9 is provided with a protrusion 10 matching the groove 7. The bottom of the sealing member 9 is provided with a notch 11 matching the convex block 8. The sealing member 9 is fixed on the C-shaped steel brace 5 by engaging the groove 7 with the protrusion 10 and the convex block 8 with the notch 11.

[0026] In this embodiment, when an opening 2 needs to be formed in the brick wall 1, first, a lintel opening 3 is formed at the upper end of the opening 2, and a lintel 4 is arranged inside the lintel opening 3. A plurality of C-shaped steel braces 5 are arranged inside the lintel 4. The C-shaped steel braces 5 play a supporting role for the lintel 4, and the lintel 4 plays a supporting role for the top of the opening 2 to be formed. When the wall inside the opening 4 is demolished later, the lintel 4 and the C-shaped steel braces 5 can also play a supporting role to ensure the stability of the entire brick wall 1. And an opening 6 is arranged on one side of the C-shaped steel brace 5 and sealed by a sealing member 9. The sealing member 9 is fixed on the C-shaped steel brace 5 by engaging the groove 7 with the protrusion 10 and the convex block 8 with the notch 11, which is convenient for disassembly so as to facilitate the installation of a finished steel skeleton and the pouring of concrete inside the lintel 4.

[0027] Specifically, when installing the finished steel skeleton, the sealing member 9 of the C-shaped steel brace 5 is removed. After the finished steel skeleton is placed in position, the sealing member 9 of the C-shaped steel brace 5 is immediately installed back to the original position to ensure the stability of the support structure.

[0028] Then, the remaining bricks at the lintel position on the existing brick wall 1 are removed, and the position of the lintel is cleared to ensure the accurate size of the lintel. After the lintel position meets the construction conditions, the already tied steel bar skeleton is placed in the position of the lintel, and pads are placed below. When the steel bar skeleton is in place, the sealing member 9 of the C-shaped steel brace 5 can be disassembled accordingly according to the position where the steel bar skeleton is placed. After the steel skeleton is in place, the steel brace sealing member is immediately restored.

[0029] After the steel skeleton is in place and fixed and the steel brace sealing piece is restored, the lintel formwork is supported, and then the concrete of the newly added cast-in-place reinforced concrete lintel is poured. This lintel is the load-bearing lintel at the top of the newly opened hole, with dimensions of 300×240×L, the reinforcement bars are 4C14 at the bottom, 2C14 at the top, the stirrups are C8@200, and the concrete strength grade is C25. The L is the length of the lintel, and the lintel length = the width of the newly opened hole + 800mm. The newly added lintel extends into both sides of the newly opened hole by not less than 400mm. It bears the load transmitted from the upper wall to ensure that the stability of the upper wall is not affected during the construction of the newly added hole below.

[0030] After the concrete strength reaches the requirement, the work of opening a large hole at the bottom of the lintel starts. Since there is a newly constructed cast-in-place reinforced concrete lintel above, the opening of the newly added hole below has no impact on the upper wall of the lintel, and it is not necessary to demolish the entire upper wall of the hole, greatly reducing the construction workload.

[0031] In some embodiments, the width of the lintel opening 3 is greater than the width of the hole 2, and the difference between their widths is not less than 400mm. To bear the load transmitted from the upper wall and ensure that the stability of the upper wall is not affected during the construction of the newly added hole 2 below.

[0032] In some other embodiments, the distance between the C-shaped steel brace 5 at both ends of the lintel opening 3 and the end of the lintel opening 3 on the same side is less than 20mm, which can play the role of the stirrup of the steel bar skeleton.

[0033] In some embodiments, the upper reinforcement of the lintel 4 is 4C14, and the lower reinforcement of the lintel 4 is 2C14.

[0034] The lintel device for the opening of the brick wall of the present utility model uses the lintel and multiple C-shaped steel braces inside the lintel to play a temporary supporting role for the upper wall of the lintel. Then, the steel brace sealing piece at the sealing position of the C-shaped steel brace can be removed to ensure that the finished steel skeleton can be directly put in, quickly positioned, the lintel steel bars are tied, and then the concrete is poured to quickly complete the construction of the newly added hole lintel. After the concrete strength of the lintel reaches the requirement, the demolition of the large hole below can be carried out safely and reliably, and it is not necessary to demolish the entire upper wall of the hole. The construction speed is fast, the cost is low, and it is safe and reliable. At the same time, the newly added lintel is used as the permanent lintel of the newly added hole and is directly put into use.

[0035] The above are only the preferred embodiments of the present utility model and are not used to limit the protection scope of the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
