Technical Field

[0001] The utility model belongs to the technical field of auxiliary tools, and in particular relates to a steel bar sleeve installation tool. Background Art

[0002] Commonly used mechanical connection methods for steel bars during construction include straight thread joints, tapered thread joints, and extrusion joints. Any of the above methods can be used for the connection of steel bars for conventional structures. However, due to cost, construction speed, and construction feasibility, the mechanical connection joints of the steel cage generally use straight thread joints, and use straight thread sleeves to connect the steel bars at both ends. At present, the straight thread sleeves are mainly installed on the construction site using two tools: an automated special steel sleeve tightening wrench and a manual ordinary wrench. The cost of the special steel sleeve tightening wrench is relatively high, and the weight of this wrench is relatively large, and the convenience of use is relatively poor; the production efficiency of ordinary wrenches is too low, and it is relatively laborious. In order to overcome the shortcomings of the above two wrenches, this application proposes a steel sleeve installation tool. Summary of the invention

[0003] In view of the above shortcomings, the technical problem to be solved by the utility model is to provide a steel sleeve installation tool for improving the installation efficiency of the straight thread sleeve, and the production cost of the installation tool is low.

[0008] As a preferred solution of the utility model, a slot is provided on the inner side wall of the connecting rod, and the rubber strip is detachably mounted on the connecting rod through the slot.

[0009] As a preferred solution of the present invention, the inclination angle of the connecting rod relative to the base is 15°-30°.

[0010] As a preferred solution of the utility model, a top pressure component is detachably mounted on the base, and the top pressure component is disposed under the steel sleeve to apply an axial force to the steel sleeve.

[0011] As a preferred solution of the utility model, the top pressure assembly includes a column, a top pressure plate and a spring. The top pressure plate is installed on the base through the column, and the spring is respectively abutted between the top pressure plate and the base.

[0012] As a preferred solution of the utility model, the diameter of the top pressure plate is larger than the diameter of the base.

[0013] As a preferred solution of the utility model, a guide groove is provided on the top pressure plate, and the connecting rod is arranged in the guide groove.

[0014] As a preferred solution of the utility model, a guide sleeve is provided in the middle of the top pressure plate, and the top pressure plate is slidably mounted on the column through the guide sleeve.

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] Embodiment 1

[0022] A steel bar sleeve installation tool. This quick installation tool includes a base 1 and at least three connecting rods 3. The connecting rods 3 are evenly arranged and connected to the base 1, and the connecting rods 3 are inclined relative to the base 1. Preferably, the connecting rods 3 are inclined relative to the base 1 at an angle of 15-30°, so that the connecting rods 3 are arranged in a trumpet shape, and the connecting rods 3 abut against the bottom edge of the steel bar sleeve 7. When the base 1 rotates, the steel bar sleeve 7 is driven to rotate by the connecting rods 3, so that the steel bar sleeve 7 is rotatably installed on the steel bar 2. Through the trumpet-shaped connecting rods 3, the installation tool can be connected to steel bar sleeves 7 of different diameters, thereby meeting the installation requirements of steel bar sleeves 7 of different diameters.

[0023] In this embodiment, the base 1 can be connected to an external power tool (such as an electric drill, etc.). By rotating the base 1, the steel sleeve 7 abutting against the connecting rod 3 is driven to rotate, thereby realizing the threaded connection between the steel sleeve 7 and the steel bar 2. The structure is simple and the production cost is low. It can be connected to the power tool, thereby greatly improving the connection efficiency of the steel sleeve 7 and the steel bar 2.

[0024] In order to facilitate the connection between the base 1 and the electric tool, a connecting column 4 is provided on the lower end surface of the base 1. The cross section of the connecting column 4 is a hexagonal structure, and the base 1 is driven to rotate through the connecting column 4.

[0025] In order to prevent the connecting rod 3 and the steel sleeve 7 from slipping and idling, a rubber strip 5 is provided on the connecting rod 3 to increase the friction between the connecting rod and the steel sleeve 7, thereby facilitating the installation tool to drive the steel sleeve 7 to rotate.

[0026] In order to facilitate replacement of the rubber strip 5 , a slot 4 - 1 is provided on the inner side wall of the connecting rod 3 , and the rubber strip 5 is detachably mounted on the connecting rod 3 through the slot 4 - 1 .

[0027] Embodiment 2

[0028] This embodiment further improves the installation tool on the basis of the first embodiment. To ensure that when the steel sleeve 7 is acted upon by the installation tool, the force on the steel sleeve 7 remains parallel to the axis of the steel bar 2, it is necessary to keep the angle between the steel sleeve 7 and the end face of the connecting rod 3 in a basically identical state. Therefore, in this embodiment, a top pressure assembly 6 is detachably installed on the base 1, and the top pressure assembly 6 is disposed under the steel sleeve 7, so that an axial force is applied to the steel sleeve 7 through the top pressure assembly 6.

[0029] The top pressure assembly 6 includes a column 6-1, a top pressure plate 6-2 and a spring 6-3. The bottom of the column 6-1 is provided with an external thread, so that the column 6-1 is installed on the base 1 through the thread. The main body of the column 6-1 is an optical axis. A hexagonal head is provided on the top of the column 6-1. On the one hand, the column 6-1 can be fixed to the base 1 by the hexagonal head, and on the other hand, the hexagonal head can limit the top pressure plate 6-2. The top pressure plate 6-2 is slidably installed on the outside of the column 6-1, and the spring 6-3 is respectively abutted between the top pressure plate 6-2 and the base 1.

[0030] When using this installation tool, the top pressure plate 6-2 abuts against the end face of the steel bar sleeve 7, so that the axis of the steel bar sleeve 7 and the axis of the installation tool are basically located in the same straight line. The installation tool can be controlled to ensure that the steel bar sleeve 7 is set directly opposite the steel bar 2, thereby improving the installation convenience of the steel bar sleeve 7.

[0031] To ensure that the top pressure plate 6 - 2 can effectively abut against the steel sleeves 7 with different diameters, the diameter of the top pressure plate 6 - 2 is larger than the diameter of the base 1 .

[0032] In order to prevent the top pressure plate 6-2 from interfering with the connecting rod 3, a guide groove 6-4 is provided on the top pressure plate 6-2, and the connecting rod 3 is arranged in the guide groove 6-4.

[0033] A guide sleeve 6-5 is provided in the middle of the top pressure plate 6-2, and the top pressure plate 6-2 is slidably mounted on the column 6-1 through the guide sleeve 6-5. The guide sleeve 6-5 can be a sliding sleeve or a linear bearing.

[0034] The rest of the structure is consistent with that of the first embodiment.
