Description

Technical Field

[0001] The invention relates to the technical field of engineering materials, and in particular to a construction engineering protection device and a protection method thereof. Background Art

[0002] Special glass such as high-performance architectural glass and building energy-saving glass refers to a type of special glass product that is processed by specific processes and added with special functional materials during the manufacturing process. High-performance architectural glass can reduce the heat exchange between the interior of the building and the external environment, effectively improve the thermal insulation performance of the building, reduce energy consumption, and enhance energy-saving effects. Special glass can control the degree of sunlight penetration inside the building by adjusting the transmitted light and infrared rays, etc., to avoid excessive heating inside the building and improve indoor comfort. In construction projects, these special glasses play a vital role.

[0003] Such glass lacks effective protection means during the stacking process before installation in construction projects. At most, it is supported by foam boards. Since the foam boards are relatively light and fragile, they are easily deformed or damaged under the weight of the glass and cannot provide sufficient stability to support and protect the glass products. Therefore, those skilled in the art provide a construction engineering protection device and a protection method thereof to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to provide a construction engineering protection device and a protection method thereof in view of the problems existing in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a construction engineering protection device, comprising a base plate, a sleeve, a guide plate, a mounting cylinder and a mounting seat, wherein the four corners of the front side of the base plate are provided with hollow sleeves inside, the front side of the base plate is provided with a symmetrically distributed mounting plate, the front end of the base plate is provided with a guide rail 1, the rear end of the mounting plate is provided with a slider 1 slidably installed in the guide rail 1, the front end of the mounting plate is provided with a guide rail 2, the rear end of the sleeve is provided with a slider 2 slidably installed on the outer wall of the guide rail 2, the interior of the sleeve is provided with a symmetrically distributed and slidably inserted mounting cylinder and a plug rod, a sealing ring slidably installed with the plug rod is embedded in the interior of the mounting cylinder, a piston slidably installed in the interior of the mounting cylinder is provided at one end of the plug rod, oil grooves are provided on the inner walls of both sides of the mounting cylinder, a mounting seat is provided at one end of the plug rod, and a spring 2 which is sleeved on the outside of the mounting cylinder and the plug rod is provided between the mounting seat and the inner wall of the sleeve.

[0006] Preferably, both ends of the oil groove are provided with oil holes, and the oil holes all penetrate the inner wall of the mounting cylinder. The oil holes are located on both sides of the piston, and the oil groove is flat as a whole and relatively distributed in a U-shape. The oil holes are located on both sides of the piston, and the piston divides the internal space of the mounting cylinder into two spaces, each of which corresponds to an oil hole penetrating the oil groove, and the oil groove is a connecting channel between the two spaces. During the movement of the piston, the hydraulic oil stored in the mounting cylinder is squeezed, and the hydraulic oil is input into different spaces through the oil holes.

[0007] Preferably, the mounting seat is provided with a rubber block at one opposite end. The rubber block has a certain degree of softness and elasticity, can provide a good buffering effect, can reduce the collision, wear or damage caused by the concentrated force when supporting the four corners of the glass, and has good anti-slip properties, can avoid accidental damage to the special glass due to movement or slipping during stacking, and the rubber block improves the protective effect of the bonding surface with the special glass.

[0008] Preferably, relatively distributed guide plates are arranged inside the ferrule, and the spacing between the guide plates decreases from the outside to the inside of the ferrule, and one end of the guide plate corresponds to the space between the mounting seats. The guide plate guides the four corners of the special glass inserted into the ferrule, inputs through the large opening of the guide plate, and effectively guides it into the space between the mounting seats through the gradually shrinking channel.

[0009] Preferably, the inner wall of the ferrule is provided with a bracket of symmetrical parts, and a spring 1 is provided between the bracket and the guide plate. The guide plate is elastically supported by the spring 1. During use, when thicker special glass passes through the guide plate, it is prevented that the relatively narrow space cannot allow the thicker special glass to pass through. The guide plate is elastically supported by the spring pair, providing a moving space for the guide plate, and the elastic support force elastically presses the two ends of the thicker special glass passing through, preventing the thicker special glass from sliding arbitrarily.

[0010] Preferably, a sliding sleeve is embedded and installed inside the bracket, and the bracket is in the shape of a 90-degree angle plate. A guide rod located inside the spring and connected to the guide plate at one end is slidably inserted inside the sliding sleeve. The bracket in the shape of a 90-degree angle plate forms an active space with the inner wall of the ferrule. When the guide rod slides inside the sliding sleeve, the sliding end moves in this space to ensure the effective sliding of the guide rod. The guide rod slides inside the sliding sleeve and guides the guide plate inside the spring, while avoiding deviation during the expansion and contraction of the spring, thereby limiting the expansion and contraction path of the spring, so that the guide plate and the spring move stably on a predetermined path.

[0011] Preferably, the front end of the bottom plate is provided with a bearing seat 1 which is symmetrically distributed and located inside the guide rail 1, a screw rod 1 with outer wall threads which are relatively distributed is rotatably inserted inside the bearing seat 1, the screw rod 1 is threadedly installed with a slider 1, and a torsion block 1 is provided at one end of the screw rod 1. Grasping the torsion block 1 facilitates applying a rotational force to the screw rod 1, and the screw rod 1 is rotationally supported by the bearing seat 1, and the slidably installed slider 1 is threadedly matched with the screw rod 1.

[0012] Preferably, the front end of the mounting plate is provided with a symmetrically distributed bearing seat 2 located inside the guide rail 2, a screw rod 2 with outer wall threads relatively distributed is rotatably inserted inside the bearing seat 2, the screw rod 2 is threadedly installed with the slider 2, and a torsion block 2 is provided at one end of the screw rod 2. Grasping the torsion block 2 facilitates applying a rotational force to the screw rod 2, and the screw rod 2 is rotationally supported by the bearing seat 2, and the slidably installed slider 2 is threadedly matched with the screw rod 2.

[0013] Preferably, a support plate is provided at the front side of the ferrule, positioning rods are provided at the four corners of the rear end of the support plate, positioning holes are provided at the four corners of the front end of the base plate, and the positioning rods are slidably inserted into the positioning holes. The support plate shields the front of the ferrule to prevent the front side of the special glass clamped in the ferrule from being exposed to the outside world. Under the direct impact of foreign objects, the support plate is effectively intercepted and protected. The support plate is inserted into the positioning hole through the positioning rod, which effectively positions and docks the base plate when it is installed.

[0014] A construction engineering protection method, the glass protection method steps are as follows:

[0015] S1: The ferrule is the four-corner support structure of the protective device. The four corners of special glass such as high-performance architectural glass and building energy-saving glass that are not installed in the construction project are inserted into the ferrule. Two groups of mounting seats in the ferrule are elastically clamped on the front and back sides of the four corners through springs and elastic support.

[0016] S2: During the storage and stacking process of special glasses such as high-performance architectural glass and building energy-saving glass, the four corners are supported to avoid direct impact of ground vibration caused during the construction process on special glasses such as high-performance architectural glass and building energy-saving glass. The impact force acts on the piston through the spring. During the movement of the piston, the hydraulic oil inside the mounting cylinder is squeezed, and the hydraulic oil is damped through the narrow oil groove, thereby applying a damping effect to the mounting seat, which plays a role in buffering the impact vibration and effectively protecting it.

[0017] S3: When screw one rotates, the threads relatively distributed on its outer wall push slider one to move. When screw two rotates, the threads relatively distributed on its outer wall push slider two to move. Sliders one and two move relative to or away from each other, thereby driving the four ferrules to adjust to different positions. During the construction process of the building project, special glasses such as high-performance architectural glass and building energy-saving glass of different specifications that are not used, stored and stacked are clamped and protected, and the adaptability of the protective device is improved.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention adjusts the edges and corners of special glasses such as high-performance architectural glass and building energy-saving glass through a clamping sleeve, and clamps the two sides of special glasses such as high-performance architectural glass and building energy-saving glass through elastically supported relative blocks. The four corners of special glasses such as high-performance architectural glass and building energy-saving glass are elastically clamped, and the impact force is effectively buffered. The high-performance architectural glass and building energy-saving glass and other special glasses with clamped edges and corners can be stacked together. During the construction process of the building project, the high-performance architectural glass and building energy-saving glass and other special glasses stored in use are effectively protected.

A screw 2 13 with relatively distributed outer wall threads is rotatably inserted inside the bearing seat 2 15. The screw 2 13 is threadedly installed with the slider 2 16. A torsion block 2 14 is provided at one end of the screw 2 13.

[0036] A support plate 1 is provided at the front side of the ferrule 7, positioning rods 3 are provided at the four corners of the rear end of the support plate 1, and positioning holes 4 are opened at the four corners of the front end of the bottom plate 2, and the positioning rods 3 are slidably inserted into the positioning holes 4;

[0037] In this embodiment, special glass such as high-performance architectural glass and building energy-saving glass is suspended on the front side of the bottom plate 2. The bottom plate 2 is placed flat on the ground when in use, so the special glass such as high-performance architectural glass and building energy-saving glass is located above the bottom plate 2. The twist block 9 is grasped to drive the screw 5 to rotate. The slider 11 is supported by the guide rail 8, and then the mounting plate 6 is guided to slide back and forth. The position introduction at this time is based on the bottom plate 2 being placed flat on the ground.

At this time, the high-performance architectural glass and building energy-saving glass are suspended on the ground, and each clamped high-performance architectural glass and building energy-saving glass can be stacked. The uppermost group is covered by the support plate 1, thereby protecting the high-performance architectural glass and building energy-saving glass. In construction projects, building materials such as high-performance architectural glass and building energy-saving glass are avoided from being easily damaged due to construction vibration or the impact of foreign objects, as well as the poor protective effect of the foam board, and effective protection is provided for special glasses such as high-performance architectural glass and building energy-saving glass.

[0039] Embodiment 2:

[0040] A sealing ring 25 is embedded in the installation cylinder 18 and is slidably mounted with a plug rod 28. A piston 26 is slidably mounted in the installation cylinder 18 at one end of the plug rod 28. Oil grooves 27 are provided on the inner walls of both sides of the installation cylinder 18.

[0041] Oil holes are provided at both ends of the oil groove 27 , and the oil holes penetrate the inner wall of the mounting cylinder 18 . The oil holes are located on both sides of the piston 26 . The oil groove 27 is flat and relatively distributed in a U shape as a whole.

[0042] In this embodiment, during the construction process, due to the vibration of the ground, or when a foreign object hits the support plate 1 longitudinally, the spring 1 22 is forced to contract, driving the mounting seat 23 to move synchronously, and the plug rod 28 is connected to the piston 26. The plug rod 28 slides inside the sealing ring 25 to maintain the seal inside the mounting cylinder 18. When the hydraulic oil is squeezed by the piston 26, the hydraulic oil in the internal space enters the oil groove 27 through the oil hole and is input to the side opposite to the squeezing force of the piston 26. Resistance is applied to the hydraulic oil when passing through the oil groove 27 and the oil hole, and a damping effect is applied to the spring 29, thereby buffering and protecting the impact force. The protective effect of special glass such as high-performance architectural glass and building energy-saving glass is improved during storage.

[0043] Embodiment three:

[0044] The interior of the ferrule 7 is provided with relatively distributed guide plates 17 , and the spacing between the guide plates 17 decreases from the outside to the inside of the ferrule 7 , and one end of the guide plate 17 corresponds to between the mounting seats 23 .

[0045] A symmetrical bracket 19 is provided on the inner wall of the ferrule 7 , and a spring 22 is provided between the bracket 19 and the guide plate 17 .

[0046] A sliding sleeve 20 is embedded and installed inside the bracket 19 . The bracket 19 is in the shape of a 90-degree angle plate. A guide rod 21 located inside the spring and connected to the guide plate 17 at one end is slidably inserted inside the sliding sleeve 20 .

[0047] In this embodiment, when special glasses such as high-performance architectural glass and building energy-saving glass are clamped in the interior of the card sleeve 7, they are guided by the guide plate 17. The guide plate 17 is convenient for guiding and plugging through the large opening of the guide plate 17. As the spacing between the guide plates 17 gradually decreases, the edges and corners of special glasses such as high-performance architectural glass and building energy-saving glass are guided between the mounting seats 23 and into the rubber seat.

[0048] Embodiment 4:

[0049] A construction engineering protection method, the glass protection method steps are as follows:

[0051] S2: During the storage and stacking process of special glasses such as high-performance architectural glass and building energy-saving glass, the four corners are supported to avoid direct impact of ground vibration caused during the construction process on special glasses such as high-performance architectural glass and building energy-saving glass. The impact force acts on the piston 26 through the spring 22. During the movement of the piston 26, the hydraulic oil inside the mounting cylinder 18 is squeezed, and the hydraulic oil is damped through the narrow oil groove 27, thereby applying a damping effect to the mounting seat 23, thereby buffering the impact vibration and providing effective protection.

[0052] S3: When the screw 1 5 rotates, the relatively distributed threads on its outer wall push the slider 1 1 to move. When the screw 2 13 rotates, the relatively distributed threads on its outer wall push the slider 2 16 to move. The slider 1 11 and the slider 2 16 move relative to or away from each other, thereby driving the four ferrules 7 to adjust to different positions. In the process of construction engineering, special glasses such as high-performance architectural glass and building energy-saving glass of different specifications that are not used, stored and stacked are clamped and protected, and the adaptability of the protective device is improved.
