Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building engineering protection devices, specifically a precast column corner protection device. Background Technology
[0002] Precast columns are concrete column components that are pre-cast in factories using standardized molds and strict processes in the industrialization of construction. They are key components that constitute the vertical load-bearing system of a building.
[0003] Nowadays, precast columns typically integrate steel reinforcement frames and high-strength concrete, and are quickly connected to foundations or beams through methods such as sleeve grouting and bolt welding to form a vertical load-bearing system for building structures. They are suitable for prefabricated housing, industrial plants, and bridge projects, and are key components that drive the construction industry toward efficiency, environmental protection, and standardization.
[0004] However, when using precast columns, due to their typically high height, they need to be laid horizontally first, then erected, and subsequently hoisted. But because of their considerable weight, the corners of the precast columns come into contact with the ground during erection, which can easily lead to the bottom corner concrete crushing. Simultaneously, the ground reaction force causes the precast columns to sway, and prolonged swaying not only increases construction time but also causes further damage to the corners due to friction with the ground, affecting the quality of the precast columns. Therefore, we propose a precast column corner protection device to effectively solve these problems. Utility Model Content
[0005] The purpose of this utility model is to provide a precast column corner protection device to solve the problems mentioned in the background art.
[0006] This utility model is achieved through the following technical solution: a precast column corner protection device, comprising four protective pads disposed at the bottom of the precast column, the four protective pads being located at the four corners of the bottom of the precast column respectively, and adjacent two protective pads being connected by an elastic band.
[0007] Optionally, the protective pad is a cube with one corner concave, and the protective pad is used to wrap around the corner of the precast column.
[0008] Optionally, the two ends of the elastic band are respectively connected to the facing surfaces of two adjacent protective pads. When the four protective pads wrap around the four corners of the precast column, the elastic band is in a stretched state.
[0009] Optionally, the elastic band and the protective pad are detachably connected.
[0010] Optionally, both ends of the elastic band are fixedly provided with buckles, and the protective pad is fixedly provided with a plug seat for inserting the buckles.
[0011] Optionally, a reinforcing block is fixed inside the protective pad, and the shape of the reinforcing block is the same as that of the protective pad.
[0012] Compared with the prior art, this utility model provides a precast column corner protection device, which has the following beneficial effects:
[0013] 1. This utility model utilizes protective pads that are adapted to the shape of the corners of the precast column to protect the corners of the precast column. The protective pads are fixed to the precast column by the connection of elastic bands, so that the protective pads will contact the ground during the process of laying the precast column from horizontal to vertical, thus avoiding the corners of the precast column from contacting the ground and causing crushing. The corners will also not rub against the ground, thus ensuring the quality of the precast column.
[0014] 2. In this utility model, the protective pad can be used as the bottom edge in turn, and the elastic band and the protective pad are detachably connected, which makes it easy for users to replace damaged parts and extend the service life; moreover, all parts are small in size and weight, quick to use and easy for staff to carry.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 - Figure 5 A precast column corner protection device includes four protective pads 1 disposed at the bottom of the precast column, with the four protective pads 1 located at the four corners of the bottom of the precast column to protect the four corners of the bottom of the precast column. Adjacent protective pads 1 are connected by elastic bands 2, which secure the protective pads 1 to the precast column, improving stability after installation and preventing the protective pads 1 from falling off.
[0023] The protective pad 1 is made of lightweight, high-strength, and tough rubber material, giving it excellent cushioning and protection. The protective pad 1 is shaped like a cube with one concave corner, with a side length of 150mm. Its three contact surfaces with the corners of the precast column are each 100mm in length and width, and its thickness is 50mm. This design ensures that the protective pad 1 completely encloses the corners of the precast column and can withstand the pressure and friction between the precast column and the ground.
[0024] On the other hand, the elastic band 2 is made of highly elastic rubber. Both ends of the elastic band 2 are connected to the facing surfaces of two adjacent protective pads 1. When the four protective pads 1 are wrapped around the four corners of the precast column, the elastic band 2 is in a stretched state. Therefore, when the four protective pads 1 are wrapped around the four corners of the precast column, the elastic band 2 can apply tension to the protective pads 1, thus ensuring that the protective pads 1 are stably fixed at the corners, preventing them from falling off during the erection or hoisting of the precast column, further improving the protection of the corners. Furthermore, the elasticity of the elastic band 2 itself allows the device to be used with precast columns with side lengths of 500mm to 1000mm, and even rectangular precast columns can be used, making it highly adaptable.
[0025] Furthermore, the elastic band 2 and the protective pad 1 are detachably connected, allowing the user to replace the damaged protective pad 1 or elastic band 2, thereby extending the service life of the device.
[0026] Specifically, both ends of the elastic band 2 are fixedly equipped with buckles 201, and the protective pad 1 is fixedly equipped with a connector 101 for inserting the buckles 201. When the buckles 201 are inserted into the connector 101, the connection between the protective pad 1 and the elastic band 2 is completed. Magnetic connection, screw connection, or other methods can be used according to actual needs.
[0027] It is worth mentioning that a reinforcing block 3 is fixed inside the protective pad 1, and the shape of the reinforcing block 3 is the same as that of the protective pad 1. The reinforcing block 3 is a thick angle iron block with a side length of 100mm and a thickness of 5mm, which greatly improves the rigidity of the protective pad 1 and prevents it from being easily damaged by the corners of the precast columns.
[0028] In this embodiment, the device is small in size and weighs no more than 3kg, making it easy to carry; and it can be installed by a single person, making it convenient and quick to use.
[0029] The working principle and usage process of this utility model are as follows: First, place the precast column horizontally on the bottom wooden block, pull the two protective pads 1 apart to be slightly larger than the width of the precast column, insert them into the gap between the precast column and the ground, and after relaxing, the protective pads 1 clamp the precast column from both sides under the contraction of the elastic band 2.
[0030] Subsequently, the other two protective pads 1 are pulled upwards so that the protective pads 1 can be locked onto the other two bottom corners of the precast column. After being relaxed, the protective pads 1 clamp the precast column from four directions under the contraction of the elastic band 2, thus completing the installation and fixing of the protective pads 1.
[0031] Then, the side of the precast column away from the protective pad 1 is hoisted and erected. During this process, the protective pad 1 will replace the corner of the precast column and contact the ground to avoid damage to the corner.
[0032] Finally, after the precast column is erected, it is lifted about 300mm off the ground. Once stable, the worker uses a long pole to press down the protective pad 1, causing the device to detach from the precast column, thus completing the use of the device.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
