Abstract

This application relates to a glass curtain wall structural adhesive testing device, belonging to the field of building curtain wall testing technology. It includes a base, with a protective box mounted on top of the base. A positive and negative threaded rod is rotatably connected inside the protective box. A limit rod is fixedly connected inside the protective box to one side of the positive and negative threaded rods. Both ends of the positive and negative threaded rods are threadedly connected to transmission blocks. The beneficial effect of this application is that the rotation of the positive and negative threaded rods drives the transmission blocks to slide along the limit rod, which in turn drives the protective side plate to open and close synchronously via a transmission linkage.

Furthermore, when the glass curtain wall body breaks due to structural adhesive failure during testing, the protective box and protective side plate effectively block flying glass fragments, preventing injury to operators and solving the problem of the lack of protective structures in existing technologies.

Description

Technical Field

[0001] This application relates to the field of building curtain wall testing technology, and in particular to a testing device for structural adhesive of glass curtain walls. Background Technology

[0002] In the field of interior decoration, glass curtain walls are often fixed to the wall openings with structural adhesive. The bonding strength of the adhesive is directly related to the safety and service life of the curtain wall. When the structural adhesive has been used for a long time or the curtain wall is frequently subjected to large wind pressure, the structural strength is easily lost, which may lead to the risk of the curtain wall falling off. Therefore, the strength testing of the structural adhesive is particularly important.

[0003] Most structural adhesive testing devices are limited to laboratory environments. They work by bonding structural adhesive between two structural components and using mechanical means such as hydraulic cylinders to pull the components, causing the structural adhesive to bear stress. The strength of the structural adhesive in actual buildings is then judged based on the tensile force data at the time of fracture, thus simulating its service life.

[0004] However, existing testing devices have significant drawbacks: they directly apply pressure using hydraulic cylinders or other driving components, lacking necessary protective structures. During the testing process, the glass curtain wall may break due to stress, and the fragments can easily injure workers. Furthermore, the scattered glass shards are difficult to clean up, which not only affects the safety of the test but also increases the workload of subsequent cleaning, making it difficult to meet the safety and convenience requirements of actual testing scenarios. Utility Model Content

This design can adjust the protection range according to the size of the glass curtain wall body to ensure reliable protection during the inspection of curtain walls of different specifications.

[0008] In a preferred embodiment, a wall is provided on the outer side of the base, and a glass curtain wall body is provided inside the wall.

[0010] In a preferred embodiment, an electric push rod is fixedly installed inside the base, and a top plate is fixedly connected to the piston rod of the electric push rod. A pressure sensor is installed on the side of the top plate near the wall, and both the pressure sensor and the top plate abut against the outer wall of the glass curtain wall body.

[0012] In a preferred embodiment, the protective box is provided with a limiting component inside. The limiting component includes limiting blocks fixedly connected to both sides of the protective side plate, and the inner wall of the protective box is provided with a limiting groove that cooperates with the limiting blocks.

[0013] By adopting the above technical solution, the cooperation between the limiting block and the limiting groove ensures that the protective side plate maintains a stable trajectory during sliding, preventing derailment due to uneven force.

[0014] In a preferred embodiment, the protective box has two mounting plates fixedly connected to the side near the base, and the mounting plates are slidably equipped with adjusting bolts.

[0015] By adopting the above technical solution and adjusting the setting of bolts and mounting plates, the protective box can be flexibly adjusted in position on the base.

[0016] In a preferred embodiment, the mounting plate is connected to the base by adjusting bolts, and the bottom of the protective box is slidably connected to the base.

[0017] By adopting the above technical solution, the protective box can be made to fit snugly against the outer wall, reducing the phenomenon of glass shards flying outward.

[0018] In a preferred embodiment, the piston rod of the electric push rod passes through the interior of the protective box, and the top of the positive and negative threaded rod extends to the outside of the protective box and is fixedly connected to a knob.

[0019] By adopting the above technical solution and using a knob, operators can rotate the forward and reverse threaded rods.

[0020] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0021] 1. In this application, the rotation of the positive and negative threaded rods can drive the transmission block to slide along the limit rod, and push the protective side plate to achieve synchronous opening and closing via the transmission connecting rod. This design can adjust the protection range according to the size of the glass curtain wall body, ensuring reliable protection during the inspection of curtain walls of different specifications. When the glass curtain wall body breaks due to the failure of the structural adhesive layer during the inspection process, the protective box and the protective side plate can effectively block the flying glass fragments, avoiding injury to the operators, thus solving the problem of lack of protective structure in the prior art. It can also allow the broken glass fragments to be collected in the wall and protective box, preventing them from scattering on the ground and greatly reducing the difficulty of cleaning.

[0022] 2. In this application, by adjusting the setting of the bolts and mounting plate, the distance between the protective box and the wall can be adjusted so that the protective box fits snugly against the outer wall, reducing the phenomenon of glass fragments splashing out.

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-4A glass curtain wall structural adhesive testing device includes a base 1, a protective box 4 on top of the base 1, a positive and negative threaded rod 10 rotatably connected inside the protective box 4, a limit rod 11 fixedly connected inside the protective box 4 and on one side of the positive and negative threaded rod 10, transmission blocks 12 threadedly connected to both ends of the outer side of the positive and negative threaded rod 10, and each transmission block 12 slidably connected to the limit rod 11, and transmission connecting rods 14 rotatably mounted at both ends of each transmission block 12, and protective side plates 5 slidably connected to both ends inside the protective box 4, with the positive and negative threaded rod 10 and the limit rod 11 positioned between the two protective side plates 5, and the protective side plates 5 rotating with the end of the transmission connecting rod 14 away from the transmission block 12. The connection is achieved by rotating the positive and negative threaded rods 10, which drives the transmission block 12 to slide along the limit rod 11. The transmission connecting rod 14 then pushes the protective side plate 5 to open and close synchronously. This design can adjust the protection range according to the size of the glass curtain wall body 7, ensuring reliable protection for curtain walls of different specifications during inspection. When the glass curtain wall body 7 breaks due to the failure of the structural adhesive layer 6 during inspection, the protective box 4 and the protective side plate 5 can effectively block the flying glass fragments, preventing injury to the operators. This solves the problem of the lack of protective structure in the existing technology and allows the broken glass fragments to be collected in the wall 2 and the protective box 4, preventing them from scattering on the ground and greatly reducing the difficulty of cleaning.

[0030] Specifically, a wall 2 is provided on the outer side of the base 1, and a glass curtain wall body 7 is provided inside the wall 2. A structural adhesive layer 6 is applied to the outer periphery of the glass curtain wall body 7, which is then bonded to the inner wall of the wall 2 via the structural adhesive layer 6. An electric push rod 3 is fixedly installed inside the base 1, and a top plate 8 is fixedly connected to the piston rod of the electric push rod 3. A pressure sensor 9 is installed on the side of the top plate 8 near the wall 2. The electric push rod 3 applies controllable pressure to the glass curtain wall body 7 through the top plate 8 and the pressure sensor 9. The pressure sensor 9 provides real-time data feedback to ensure proper detection. The pressure value is precisely controlled during the process to simulate the stress state under real use environment. The pressure sensor 9 and the top plate 8 are both in contact with the outer wall of the glass curtain wall body 7. The protective box 4 is equipped with a limit component, which includes a limit block 15 fixedly connected to both sides of the protective side plate 5. Through the cooperation of the limit block 15 and the limit groove 13, the protective side plate 5 is ensured to maintain a stable trajectory during sliding, preventing derailment due to uneven force, and further improving the reliability of the protective structure. The inner wall of the protective box 4 is provided with a limit groove 13 that cooperates with the limit block 15.

[0031] Specifically, two mounting plates 16 are fixedly connected to the side of the protective box 4 near the base 1. Adjusting bolts 17 are slidably installed inside the mounting plates 16. By adjusting the bolts 17 and the mounting plates 16, the protective box 4 can be flexibly adjusted on the base 1 to facilitate alignment with the glass curtain wall body 7 at different positions. The mounting plates 16 are connected to the base 1 by the adjusting bolts 17. The bottom of the protective box 4 is slidably connected to the base 1. The piston rod of the electric push rod 3 passes through the interior of the protective box 4. The knob allows the operator to rotate the positive and negative threaded rod 10. The top of the positive and negative threaded rod 10 extends to the outside of the protective box 4 and is fixedly connected to the knob.

[0032] Working principle: First, the testing device can be placed on the wall 2 and the base 1 can be fixed. Then, by adjusting the setting of the bolt 17 and the mounting plate 16, the distance between the protective box 4 and the wall 2 can be adjusted so that the protective box 4 fits against the outer wall of the wall 2. At the same time, the protective box 4 is installed on the base 1 using the adjusting bolt 17, and the knob is turned so that the positive and negative threaded rod 10 rotates, which drives the transmission block 12 to slide along the limit rod 11. Through the transmission connecting rod 14, the protective side plate 5 is pushed to open and close synchronously. This design can adjust the protection range according to the size of the glass curtain wall body 7 to ensure reliable protection when testing curtain walls of different specifications. When the glass curtain wall body 7 breaks due to the failure of the structural adhesive layer 6 during the testing process, the protective box 4 and the protective side plate 5 can effectively block the flying glass fragments to avoid injury to the operators. The electric push rod 3 applies controllable pressure to the glass curtain wall body 7 through the top plate 8 and the pressure sensor 9. The pressure sensor 9 provides real-time feedback data to ensure accurate control of the pressure value during the testing process and simulate the stress state under real use conditions.
