Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a double cantilever slab support and reinforcement structure. Background Technology

[0002] A cantilever slab is a slab-like structural member with rigid support at only one end and complete freedom at the other, without any downward support. It is widely used in construction, such as balconies, canopies, and equipment platforms. With the increasing complexity of modern building structures, the construction of cantilever slabs faces new challenges. Currently, the distance between two cantilever slabs (double cantilever slabs) in many buildings is not fixed, especially in some narrow gaps, causing numerous problems for cantilever slab construction, particularly in formwork support. To address the difficulties in formwork support, existing solutions involve custom-made support rods of length corresponding to the slab spacing for reinforcement. However, this solution not only requires multiple sets of support rods of different sizes, increasing costs, but also makes installation and removal difficult in narrow slab spacing situations. Utility Model Content

[0003] To solve the above problems, this utility model provides a double-cantilever plate support and reinforcement structure, characterized in that the structure includes:

[0004] The first support member is arranged along the first direction at the bottom of the cantilever plate to support the cantilever plate;

[0005] The second support member is arranged along the first direction at the bottom of the cantilever plate to support the cantilever plate;

[0006] The third support member, arranged along the second direction, is used to connect the first support member and the second support member;

[0007] The first support member can be adjusted in position on the third support member to change the distance between it and the second support member.

[0008] Furthermore, the first support member and the second support member are respectively connected to the first end and the second end of the third support member.

[0009] Furthermore, the first end of the third support member is provided with several connecting holes arranged along the second direction.

[0010] Furthermore, the first support member is connected to the third support member through the connecting hole of the third support member.

[0011] Furthermore, the first support member can be connected to the second support member via connection holes at different positions on the third support member to adjust the distance between them.

[0012] Furthermore, the first support member has a connecting hole at its first end, and the connecting hole of the first support member and the connecting hole of the third support member are connected by a detachable pin to make the first support member and the third support member detachably connected together.

[0013] Furthermore, the first direction and the second direction are perpendicular to each other.

[0014] Furthermore, the structure also includes a fourth support member, which is obliquely connected between the third support member and the second support member.

[0015] Furthermore, the connection between the third support member and the fourth support member is located at a non-end position of the third support member.

[0016] Furthermore, the second support member and the third support member are welded together, and the two ends of the fourth support member are welded together with the second support member and the third support member.

[0017] The beneficial contribution of this utility model lies in its effective solution to the aforementioned problems. This utility model adjusts the distance between the first and second support members by adjusting the position of the first support member on the third support member, thereby accommodating double-cantilever slabs with different vertical spacing. Furthermore, this utility model achieves rapid installation and disassembly through pins and tabs, without operating inside the double-cantilever slab, thus maintaining installation and disassembly speed even with narrow slab spacing. This utility model is convenient to install and disassemble, has high applicability, and can effectively reduce project procurement costs. Attached Figure Description

[0019] The attached diagrams are labeled as follows: First support member 10, Second support member 20, Third support member 30, Fourth support member 40, Connecting hole 50, Fixing hole 60. Detailed Implementation

[0020] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0021] This example provides a double-cantilever board support and reinforcement structure, including: a first support member 10, a second support member 20, and a third support member 30. The first support member 10 is arranged along a first direction at the bottom of the lower cantilever board to support it; the second support member 20 is arranged along the first direction at the bottom of the upper cantilever board to support it; the third support member 30 is arranged along a second direction to connect the first support member 10 and the second support member 20. The first support member 10 can be adjusted in position on the third support member 30 to change the distance between it and the second support member 20.

[0022] The second support member 20 is located at the bottom of the cantilever slab formwork along the first direction, directly bearing the weight of the cantilever slab concrete, the self-weight of the formwork, and the downward pressure generated by the construction load, thus providing support and protection for the cantilever slab formwork.

[0023] Furthermore, the pressure received by the second support member 20 is transmitted to the first support member 10 through the third support member 30.

[0024] The first support member 10 is located at the bottom of the cantilever slab formwork along the first direction, directly bearing the weight of the cantilever slab concrete, the self-weight of the formwork, the downward pressure generated by the construction load, and the force transmitted from the third support member 30, thus providing support and protection for the cantilever slab formwork.

[0025] The bottom of the first support member 10 is provided with scaffolding support, which transmits the pressure on the first support member 10 to the ground or a reliable structure below (such as floor slabs, beams, columns). The specific structure of the scaffolding is existing technology and will not be described in detail here.

[0026] Furthermore, the second direction is perpendicular to the first direction.

[0027] Furthermore, the first support member 10 and the second support member 20 are respectively connected to the first end and the second end of the third support member 30.

[0028] Furthermore, the first end of the third support member 30 is provided with several connecting holes 50 arranged along the second direction.

[0029] Furthermore, the third support member 30 includes a main board and two side plates. The length direction of the main board and the side plates is parallel to the second direction. The two side plates are arranged on both sides of the main board and are perpendicular to the main board. The connection hole 50 of the third support member 30 is located on the main board.

[0030] Furthermore, the first support member 10 is connected to the third support member 30 through the connection hole 50 of the third support member 30.

[0031] Furthermore, the first support member 10 can be connected to the second support member 20 through connecting holes 50 at different positions on the third support member 30 to adjust the distance between them, so as to accommodate double cantilever boards with different vertical spacing.

[0032] Furthermore, the side plate of the third support member 30 is provided with several fixing holes 60 arranged along the second direction. The fixing holes 60 are used to detachably connect the third support member 30 to the cantilever plate template, thereby increasing the stability of the reinforcement structure.

[0033] In this example, the first support member 10 is a cuboid structure with one face being open, i.e., an open face, so that the first support member 10 forms a cavity.

[0034] Furthermore, the open surface is parallel to the first direction and perpendicular to the second direction.

[0035] Furthermore, the first support member 10 is provided with a connection hole 50 at its first end. The connection hole 50 of the first support member 10 and the connection hole 50 of the third support member 30 are connected together by a detachable pin, which has the characteristics of quick assembly and disassembly, and is convenient for on-site installation, disassembly and reuse.

[0036] Furthermore, the connecting hole 50 at the first end of the first support member 10 is located on a plane that is perpendicular to the first direction and parallel to the second direction.

[0037] Furthermore, this example also includes a fourth support member 40, which is obliquely connected between the second support member 20 and the third support member 30.

[0038] Furthermore, the fourth support member 40, together with the second support member 20 and the third support member 30, forms a stable triangular structure. The fourth support member 40 not only enables the second support member 20 to better transmit pressure to the third support member 30, but also enhances the stability of the second support member 20 and the third support member 30.

[0039] Furthermore, there are two fourth support members 40, which are symmetrically distributed and whose axis of symmetry is parallel to the first direction.

[0040] Furthermore, the connection between the third support member 30 and the fourth support member 40 is located at a non-end position of the third support member 30.

[0041] Furthermore, the second support member 20 and the third support member 30 are welded together, and the two ends of the fourth support member 40 are welded together with the second support member 20 and the third support member 30, which has the characteristics of stability and long-term maintenance-free operation.

[0042] In use, the second support member 20 is placed at the bottom of the upper cantilever plate template, and the third support member 30 is perpendicular to both the upper and lower cantilever plates. The third support member 30 is connected to the lower cantilever plate template through the fixing hole 60. The first support member 10 is placed at the bottom of the lower cantilever plate template, parallel to the second support member 20, with its open surface facing downwards and away from the lower cantilever plate. The connecting hole 50 at the first end of the first support member 10 and the connecting hole 50 of the third support member 30 are detachably connected together by a pin. The scaffolding supports the first support member 10, thereby supporting the entire reinforced structure.

[0043] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
