Description

Technical Field

[0001] The utility model relates to the technical field of concrete composite slab protection, in particular to a component corner protection mechanism for installing concrete composite slabs. Background Art

[0002] A concrete composite slab is composed of a precast concrete base plate (prefabricated in a factory) and an on-site post-cast composite layer of concrete (cast at the construction site). Certain structural measures are used to ensure that the two are subjected to stress together to form a whole floor or stair slab structure. This is a structural component that is widely used in modern buildings, especially prefabricated buildings. It cleverly combines the advantages of both prefabrication and cast-in-place processes. When the composite slab is used, it is usually hoisted to a predetermined position by a hoist and then assembled one by one like building blocks to form a platform. Due to factors such as the prefabrication process or the bonding ability of the materials, the edges and corners of the composite slab are extremely easy to be damaged during the splicing process, which leads to a decrease in the overall fit of the platform, a decrease in sealing, and the occurrence of many problems such as affecting subsequent work. The existing protective structure is an integral frame structure, which is directly covered by a metal sleeve of appropriate size on the edges and corners to achieve a protective effect. However, due to many problems such as fixed specifications and loose sleeves, it has poor adaptability and is unreliable. Therefore, the present invention improves the existing equipment to address the above problems. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example: See Figure 1-5 The utility model discloses a corner protection mechanism for components used in the installation of concrete composite slabs, comprising a connecting column 1, an upper connecting block 2 being provided at the upper end of the connecting column 1, a locking assembly being provided between the connecting column 1 and the upper connecting block 2, a lower connecting block 3 being provided at the lower end of the connecting column 1, an adjusting assembly being provided between the connecting column 1 and the lower connecting block 3, and protective assemblies being provided on both the upper connecting block 2 and the lower connecting block 3. The structure of the mechanism is simple and firm, convenient for repeated use, and improved practicality; the locking assembly comprises a pull rod 4 installed at the top end of the connecting column 1, a limit plate being fixed to the top surface of the pull rod 4, and a movable ring being provided on the outer movable sleeve of the pull rod 4 Plate, both sides of the top of the movable ring plate are vertically fixed with guide rods 5, the top of the guide rod 5 is movably passed through the top surface of the upper connecting block 2, and a spring 7 is movably sleeved on the pull rod 4 between the movable ring plate and the limit plate. The bottom of the upper connecting block 2 is equipped with a receiving groove for cooperating with the locking assembly, and the movable ring plate, the limit plate and the spring 7 are all located in the receiving groove. The guide rod 5 passes through the upper connecting block 2 and is connected with a pin shaft, and an L-shaped crank handle 6 is movably hinged on the pin shaft. The bottom surface of the crank handle 6 is movably abutted against the top surface of the upper connecting block 2. Through the cooperation of the spring 7 and the pull rod 4, it is convenient to continuously lock the composite plate, thereby improving practicality.

[0020] In the present invention, the adjusting assembly includes a connecting column 1, an anti-slip groove is provided on the upper part of the outer side surface of the connecting column 1, an external thread is provided on the lower end of the outer side surface of the connecting column 1, and a threaded hole is vertically opened and closed at one corner of the top of the lower connecting block 3. The lower end of the connecting column 1 is screwed and connected to the threaded hole of the lower connecting block 3, and the bottom surface of the lower connecting block 3 is abutted with a nut 8, which is screwed and connected to the lower part of the connecting column 1. Through the cooperation of the connecting column 1 and the nut 8, the overall length of the mechanism is conveniently adjusted, thereby improving practicality; the protective assembly includes a protective plate 9 installed on the top of the upper connecting block 2 and the bottom of the lower connecting block 3, and the opposite surfaces of the two protective plates 9 are protruded with a right-angled bend-shaped baffle 10. Through the cooperation of the connecting column 1 and the nut 8, the overall length of the mechanism is conveniently adjusted, thereby improving practicality;

[0021] Working principle: When using the present invention, first hold the anti-slip groove position on the connecting column 1 with one hand according to the target thickness of the composite plate, and turn the nut 8 with the other hand, then adjust the lower connecting block 3 to adjust the mechanism to the appropriate overall length, and then abut the bottom surface of the protective plate 9 on the upper connecting block 2 against the top surface of the composite plate, and at the same time abut the inner surface of the baffle 10 against the right-angle side of the composite plate, and then bend the crank handle 6 forward to move the guide rod 5 upward. The upward movement of the guide rod 5 will drive the spring 7 to move upward, thereby driving the pull rod 4 on the connecting column 1 to move upward. After the connecting column 1 moves upward for a certain distance, the top surface of the protective plate 9 on the lower connecting block 3 abuts the bottom surface of the composite plate, and the connecting column 1 stops moving. At this time, the guide rod 5 continues to move and will squeeze the spring 7, so that the spring 7 continues to apply tension to the connecting column 1. After locking is completed, it can be hoisted to the target position.
