Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering guardrails, and in particular to a BIM-based construction engineering guardrail. Background Art

[0002] BIM construction projects refer to engineering projects that use BIM technology for architectural design, construction and management. BIM is a digital modeling tool that integrates information from the fields of architectural design, structural engineering and construction management, and combines data and information from various stages such as design, construction and operation, so that all relevant parties can obtain consistent project information and work together.

[0003] When carrying out construction, it is often necessary to set up guardrails to ensure construction safety. The existing Chinese patent with authorization announcement number CN213898416U discloses a BIM-based guardrail for construction projects. It is provided with multiple threaded sleeves, screws and corresponding bevel gears, which is convenient for reducing the total volume of the entire guardrail by rotating the knob and the handle in the opposite direction after use, making it convenient for transportation, meeting the use requirements and being easy to use.

[0004] Among them, guardrails are commonly used facilities in construction, which generally include brackets and railing pillars. Some detachable guardrails will also add connectors to increase the stability of the guardrails. BIM technology can also be used to simulate the construction process, including the placement and fixing methods of guardrails during construction, so as to achieve scientific construction. However, in actual construction, the structure of the guardrail does not match the actual ground. It is easy to shake when placed on the ground. When encountering external impact, it is easy to topple over, affecting normal use. Utility Model Content

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a BIM-based guardrail for construction projects. The BIM-based guardrail for construction projects includes a base 1 and a pillar 2. A reinforcing mechanism 3 is arranged on the inner side of the base 1. The reinforcing mechanism 3 includes a support member 31. The support member 31 includes a support frame 311. The support frame 311 is hinged on both sides of the pillar 2 and at the top of the base 1. An auxiliary support leg 312 is hinged at one end of the support frame 311 away from the pillar 2. A reinforcing shaft 314 is movably connected to the top of the auxiliary support leg 312 and on the inner side of the support frame 311. The other end of the reinforcing shaft 314 is connected to a load seat 315. The load seat 315 is movably connected to the inner side of the pillar 2. The base 1 is also provided with a height adjusting member 4, and the height adjusting member 4 is located at the top of the reinforcing mechanism 3.

[0030] A positioning shaft 316 is fixedly installed on the inner side of the pillar 2 . One end of the positioning shaft 316 close to the base 1 passes through the entire load seat 315 . A spring 317 is arranged on the outer side of the positioning shaft 316 and on the top of the load seat 315 .

[0031] A locking frame 318 is fixedly installed on one side of the pillar 2, and the locking frame 318 and the load seat 315 are adapted to each other. Buckle frames 319 are also movably connected on both sides of the pillar 2, and the buckle frames 319 correspond to the support frames 311 one by one.

[0032] When placing the guardrail, the BIM technology is used to simulate the placement and fixing method of the guardrail during the construction process. The guardrail is placed according to the plan, and the base 1 connected to the pillar 2 is placed on the ground in the target area. When the pillar 2 is found to be shaking, the buckle frame 319 located in the groove of the pillar 2 is pushed upward to unfold the support frame 311 folded in the pillar 2, and the auxiliary leg 312 is unfolded so that the bottom of the auxiliary leg 312 is flush with the bottom of the base 1. The spring 317 in the pillar 2 gradually extends to push the load seat 315 to the base 1 under the restriction of the positioning shaft 316. The guide slider 313 moves to one side, and in this process, the reinforcing shaft 314 is used to make the guide slider 313 move in the support frame 311 to the side away from the pillar 2, and when the maximum moving distance is reached, the angle between the support frame 311 and the pillar 2 is ninety degrees, and a relatively stable triangular structure is formed on both sides of the pillar 2. When the device is hit, the deformation of the spring 317 is used to reduce the impact, thereby preventing the device from tipping over. When the load seat 315 is at the lowest height, the locking frame 318 that is clamped with the load seat 315 is connected by a bolt, so that the height of the load seat 315 in the pillar 2 is determined.
