Description

Technical Field

[0001] This utility model belongs to the field of building wall construction equipment and facilities, and particularly relates to an auxiliary device for installing shear walls in laboratory buildings. Background Technology

[0002] The construction cycle of laboratory buildings is affected by various factors. Generally speaking, from planning and design to final acceptance, the construction cycle for small laboratories may be 6-12 months, for medium-sized laboratories it may be 1-2 years, and for large and complex laboratories it may be 2-3 years or even longer. To shorten the construction cycle of laboratory buildings, prefabricated walls can be used. In addition to high construction efficiency, prefabricated building walls also have advantages such as good quality control, energy saving and environmental protection, and high space utilization.

[0003] Existing patent CN202320153202.4 discloses a precise positioning device for installing precast shear walls, which includes positioning guide rails for fixing to both sides of the precast shear wall and a pair of brackets. Each positioning guide rail extends vertically, and each of the two brackets has a guide member for connecting to the positioning guide rail on its adjacent side. The guide member includes a horizontal support rod and a telescopic diagonal rod. One end of each telescopic diagonal rod is hinged to each bracket, and the other end of each telescopic diagonal rod is hinged to each horizontal support rod. One end of each horizontal support rod is hinged to each bracket, and the other end of each horizontal support rod is fixed with a telescopic arm pulley. Each telescopic arm pulley is slidably installed on each positioning guide rail. This device enables the pre-drilled holes for the reinforcing bars of the shear wall to accurately and quickly align with the reinforcing bars of adjacent walls, thereby improving the construction efficiency of precast shear walls. However, the problem with this device in actual use is that, since it needs to be positioned, supported and guided from both sides of the shear wall, as the number of building floors increases, it is not possible to build a support system that meets the requirements of this device, making it inconvenient to carry out assembly work. In addition, it also requires at least two people to hold the gradually descending wall, which also poses a certain degree of danger. Utility Model Content

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Examples, such as Figures 1-6 As shown, this utility model provides an auxiliary device for installing a shear wall in a laboratory building, including a guide rail 2. The guide rails 2 are paired on one side of the shear wall 1. A bracket 3 is provided diagonally below the guide rail 2. The bracket 3 includes a pair of fixed hinge supports 31 set on the ground. A support rod 32 and a top rod 33 are respectively provided on the two fixed hinge supports 31. The top rod 33 is connected to the support rod 32 in a V-shape. A support hinge 34 is provided at the top of the top rod 33. A pulley 35 is rotatably mounted on the support hinge 34. The cross surface of the guide rail 2 is E-shaped and includes two parallel... The first guide section 21 and the second guide section 22 are distributed. The first guide section 21 rolls with the wheel surface of the pulley 35. The second guide section 22 is provided with an upper guide opening 221 and a lower guide opening 222. The top end of the upper guide opening 221 and the bottom end of the lower guide opening 222 are both open ends. A manual traction component 4 is provided in the extending direction of the upper guide opening 221 and the lower guide opening 222. The manual traction component 4 includes a horizontal bar 41 and a vertical bar 42 connected in a T-shape. The end of the horizontal bar 41 is provided with a roller 43 for rolling with the second guide section 22.

[0023] Specifically, the top of the shear wall 1 is equipped with a hoisting node, facilitating the installation of the shear wall 1 by a crane to the assembly point on the building. Each guide rail 2 corresponds to a set of brackets 3, which are installed on the building ground via fixed hinges 31. These brackets serve two purposes: guiding the installation of the shear wall 1 and providing lateral support for the shear wall 1, facilitating the installation and pouring of hidden beams and columns around the shear wall 1. Furthermore, both the guide rails 2 and brackets 3 are located on one side of the shear wall 1. This single-sided support method is suitable for the installation of wall panels in high-rise buildings, eliminating the need to lay brackets 3 on both sides of the shear wall 1. Further still, during the process of lowering the shear wall 1 to the corresponding point, a worker uses a manual traction component 4 in conjunction with the guide rails 2. If the shear wall 1 is still in the air, the horizontal bar 41 of the manual traction component 4 can be slid into the guide rail 2 from the lower guide opening 222, applying a force with a horizontal branching direction to the vertical bar 42 to support the shear wall 1. The traction action assists the crane in positioning the shear wall 1 against the guide rail 2 and the pulley 35 in the direction of their engagement. Furthermore, as the shear wall 1 descends to near the ground, the horizontal bar 41 of the manual traction assembly 4 can slide from the upper guide port 221 into the guide rail 2, applying a force with a horizontal branching direction to the vertical bar 42. This force, combined with the supporting force of the bracket 3, creates a relatively flexible clamping force, allowing the shear wall 1 to be assembled stably and safely along the supporting direction of the bracket 3. This not only meets the construction requirements for building prefabricated structures in laboratories but also offers high safety and strong practicality.

[0024] To improve the safety of the manual traction assembly 4, the manual traction assembly 4 provided by this utility model further includes a three-way connector 44. A core rod 45 is provided at the center of the two opposite ends of the three-way connector 44. A T-shaped connecting sleeve 46 is provided on the core rod 45 to limit the axial position of the three-way connector 44. Threaded hinge joints 47 are threadedly connected to both ends of the core rod 45. The other end of the threaded hinge joint 47 is a hinge shaft connection end. One end of the crossbar 41 is axially connected to the threaded hinge joint 47. In this way, the crossbar 41 can form a folding relationship with the vertical rod 42 through its axial connection with the threaded hinge joint 47, facilitating retraction. The bottom of the three-way connector 44 is connected to the vertical rod 42. By manually moving the vertical rod 42, the core rod 45, the crossbar 41, and the roller 43 can produce corresponding rolling movements, allowing the roller 43 to enter the second guide section 22 along the surface of the shear wall 1 for corresponding traction actions. It should be noted that since the roller 43 is in a rolling relationship with the upper guide port 221 and the lower guide port 222, and the upper guide port 221 and the lower guide port 222 have sufficient length, the lifting action of the crane will not be excessively affected during the manual application of traction force, thus ensuring the safety of the shear wall 1 movement.

[0025] To improve the utilization rate of the manual traction assembly 4, the vertical rod 42 provided by this utility model is a two-section telescopic rod, comprising a telescopic section 421 and a handle section 422. A hinge plate 423 is provided on the side of the telescopic section 421, and a pull rod 48 extending towards the end of the handle section 422 is provided on the hinge plate 423. In this way, by moving the pull rod 48 by hand, the combined length of the telescopic section 421 and the handle section 422 can be changed accordingly. This satisfies the usage habits of different workers and allows for flexible adjustment based on the actual height of the wall during assembly, ensuring the practicality of the manual traction assembly 4.

[0026] Considering the support requirements of the shear wall 1 after it is settled, and in order to make full use of the bracket 3, the pulley 35 provided by this utility model is provided with multiple indexing holes 36 arranged in a circular array with its rolling center as the center. The side of the first guide section 21 is provided with multiple waist-shaped holes 211 corresponding to the indexing holes 36. The outer side of the first guide section 21 is provided with an anti-detachment rod 5 connecting the waist-shaped holes 211 to the indexing holes 36. In this way, the pulley 35 not only serves to guide the rolling along the guide rail 2, but also cooperates with the anti-detachment rod 5 at its end point of movement to prevent it from falling over. Moreover, the bottom of the shear wall 1 also has bottom reinforcement to complete the support cooperation with the ground, which facilitates the subsequent installation or pouring of hidden beams and hidden columns on the shear wall 1.

[0027] Furthermore, the anti-detachment rod 5 is L-shaped, with the short end of the anti-detachment rod used to connect the indexing hole 36 and the waist-shaped hole 211, while the long section of the anti-detachment rod 5 is used for hand-holding, making it convenient to pick up, put down and disassemble.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
