Description

Technical Field

[0001] This utility model relates to an anti-overturning device for a cap beam pouring construction platform, which is a device to prevent the construction platform from overturning during cap beam pouring construction, and belongs to the field of cap beam construction technology. Background Technology

[0002] During the pouring of the cap beam, construction needs to be carried out on the construction platform. The construction platform is generally constructed by setting longitudinal main beams on both sides of the pier and setting several crossbeams at intervals on the upper part of the two longitudinal main beams as the support for the construction platform. However, near the pier, the crossbeams cannot be passed through, resulting in the formwork and construction platform forming a single support point on the crossbeams. When the cantilever of the construction platform is too large, it is easy to cause the risk of overturning. Utility Model Content

[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a simple structure for preventing the overturning of a cap beam casting construction platform.

[0004] This utility model is achieved through the following technical solution: an anti-overturning device for a cap beam casting construction platform, comprising a longitudinal main beam located on the side of the pier, characterized in that: two longitudinally arranged first fixed beams are provided on the upper part of the construction platform near the pier, the two first fixed beams are respectively arranged on both sides of the longitudinal main beam, and multiple second fixed beams are arranged longitudinally at intervals on the lower part of the longitudinal main beam, the second fixed beams are arranged laterally, the first fixed beams and the second fixed beams are both double-channel steel, and the two first fixed beams are respectively anchored to the longitudinal main beam by tensioning with the second fixed beams using precision-rolled threaded steel.

[0005] In this invention, the first fixed beam and the second fixed beam are connected by two precision-rolled threaded steel bars, which can fix the construction platform close to the pier body to the longitudinal main beam. This can transfer the overturning moment of the construction platform to the longitudinal main beam and avoid the danger of platform overturning.

[0006] Furthermore, to ensure reliable anchoring between the construction platform and the longitudinal main beam, the interval between the second fixed beams is 50cm.

[0007] Furthermore, both the first and second fixed beams are made of double-splitting 10# channel steel.

[0008] Furthermore, the diameter of the precision-rolled threaded steel bar is 25mm.

[0009] The beneficial effects of this utility model are as follows: By setting two first fixed beams on the upper part of the construction platform near the pier and multiple second fixed beams on the lower part of the longitudinal main beam, and connecting the first and second fixed beams with two precision-rolled threaded steel bars, the construction platform near the pier is anchored to the longitudinal main beam. The overturning moment of the construction platform can be transferred to the longitudinal main beam through the tension structure, effectively preventing the construction platform from overturning. This effectively solves the problem of existing cap beam casting construction platforms being prone to overturning due to excessive cantilever. This utility model has a simple structure, is easy to process and manufacture, and has low cost. Both the first and second fixed beams are made of double-channel steel, resulting in high structural strength, high reliability during tension anchoring, and safe and reliable construction.

[0013] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0014] As shown in the attached diagram, an anti-overturning device for a cap beam casting construction platform includes a longitudinal main beam 3 located on the side of the pier 7. The longitudinal main beam 3 is part of the original design of the cap beam casting construction platform. One longitudinal main beam 3 is installed on each side of the pier 7, and a construction platform crossbeam 1.1 is erected on top of the longitudinal main beam 3. Its characteristic is that two longitudinally arranged first fixed beams 2 are installed on the upper part of the construction platform 1 near the pier 7, respectively, on both sides of the longitudinal main beam 3. Multiple second fixed beams 5 are arranged longitudinally at intervals below the longitudinal main beam 3, and are arranged transversely. Both the first fixed beams 2 and the second fixed beams 5 are double-splittered channel steel. To ensure structural strength, it is preferable that both the first fixed beams 2 and the second fixed beams 5 are made of 10# channel steel in double-splittered form. The second fixed beams 5 are anchored to the two upper first fixed beams 2 by two precision-rolled threaded steel bars 4. To ensure the reliability of the tie structure, it is preferable that the fine-rolled threaded steel bar 4 is made of fine-rolled threaded steel bar with a diameter of 25mm.

[0015] To ensure reliable anchoring between the construction platform and the longitudinal main beam 3, it is preferable that the second fixed beam 5 is spaced 50cm apart.

[0016] This utility model uses a first fixed beam 2, a second fixed beam 5, and a precision-rolled threaded steel bar 4 for tie rods to fix the construction platform close to the pier body to the longitudinal main beam. The tie rod structure can transfer the overturning moment of the construction platform to the longitudinal main beam, which can effectively prevent the construction platform from overturning. It can effectively solve the problem that the existing cap beam casting construction platform is prone to overturning due to excessive cantilever.

[0017] The other parts in this embodiment are all existing technologies and will not be described in detail here.
