Description

Technical Field

[0001] The present invention relates to the technical field of clamping and fixing, and particularly to a butt joint assembly device for building steel frames. Background Art

[0002] Steel members refer to steel structure composite members that can bear and transfer loads, which are formed by connecting steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-beams through cold bending or welding with connectors. The steel member system has comprehensive advantages such as light self-weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, it has unique advantages in the development of "high, large, and light" aspects.

[0003] During the construction process of steel frames, connections need to be made between steel structural members, and the connection methods include welding, bolt nuts, riveting, etc. For the welding method, it is necessary to fix two mutually connected steel members and then perform welding treatment. During on-site welding, most of the time, two members are placed opposite each other and then directly welded, resulting in uncontrollable welding quality. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a butt joint assembly device for building steel frames, which includes a first clamping unit and a second clamping unit. One side of the first clamping unit is fixedly connected with a plug rod, and one side of the second clamping unit is fixedly connected with a sleeve. The plug rod extends into the interior of the sleeve. That is, the first clamping unit and the second clamping unit are connected through the plug rod and the sleeve, and at the same time, controlling the length of the plug rod inserted into the sleeve controls the distance between the first clamping unit and the second clamping unit.

[0005] The first clamping unit and the second clamping unit are the same, and both include a base. One side of the upper end of the base is provided with a baffle, and a clamping block is slidably arranged on the upper end of the base. The lower part of the clamping block is threadedly engaged with a second screw rod. Place the steel member on the base, and at the same time make one side fit against the baffle, then rotate the second bolt, and the clamping block threadedly connected with it moves towards the steel member and clamps and fixes it.

[0006] Preferably, a first bolt is threadedly connected to the upper end of the sleeve, and the lower end of the first bolt abuts against the plug rod. After the distance between the first clamping unit and the second clamping unit is determined, tighten the first bolt and tightly abut against the plug rod to fix the positions between the first clamping unit and the second clamping unit.

[0007] Preferably, a T-shaped groove is provided on the upper end of the base, and the T-shaped groove is perpendicular to the baffle. The lower part of the clamping block is slidably fitted inside the T-shaped groove. That is, the clamping block is slidably arranged in the T-shaped groove.

[0008] Preferably, one end of the second screw rod is fixedly connected with a regular hexagon bayonet. That is, tools such as a wrench can be used to hold the regular hexagon bayonet to rotate the second screw rod, thereby adjusting the position of the clamping block. In addition, it should be noted that the type of the second screw rod is a self-locking type, that is, the clamping block cannot act in the reverse direction and cause the second screw rod to rotate.

[0009] Preferably, an opening is provided on the lower side wall of the clamping block. Since most of the steel members to be clamped are angle steel and channel steel, the provided opening is used to clamp the edge of the steel member to achieve stable clamping of the steel member.

[0010] Preferably, a fixing plate is provided on one side of the base, and one end of the second screw rod passes through the fixing plate. A number of second bolts are provided on the fixing plate, and the second bolts are threadedly connected to the base. That is, the fixing plate is used to support the second screw rod. At the same time, the second screw rod and the fixing plate are rotatably connected, and the provided second bolts are used for the fixed connection of the fixing plate.

[0011] Preferably, first screw rods are rotatably connected to both sides of the upper end of the base. A pressing rod and a nut are provided on the first screw rod. The nut is threadedly connected to the first screw rod, and the nut is located above the pressing rod. When clamping with a baffle and a clamping block, when the height of the steel member is relatively large, it is easy to fall off the clamping. Therefore, first screw rods and cross bars are provided. After the steel member is clamped, the first screw rod is set vertically at this time, and the pressing rod is sleeved. The lower part of the pressing rod is the steel member, and then the nut is tightened to limit the pressing rod, and finally the fixation of the steel member is achieved.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. A first clamping unit and a second clamping unit are provided, and the connected steel member is fixed by using a baffle and a clamping block. After placing the steel member on the base, tools such as a wrench are used to hold the regular hexagon bayonet to rotate the second screw rod, and controlling the clamping block can achieve the fixation of the steel member. This method is simple to operate and at the same time ensures that the positions of the two steel members will not change during the welding process.

[0014] 2. A first screw rod, a pressing rod and a nut are provided. When the volume of the clamped steel member is large, these components can be used to hold and fix the steel member, improving the stability of the fixation and thus improving the docking quality of the steel member.

[0021] The present invention will be further clarified below in conjunction with the drawings and specific implementation manners. It should be understood that the following specific implementation manners are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0022] As Figures 1 to 4 shown, the docking and assembly device for building steel frames includes a first clamping unit 1 and a second clamping unit 5. The first clamping unit 1 and the second clamping unit 5 are respectively used to fix two steel members that are about to be connected to each other. One side of the first clamping unit 1 is fixedly connected with a plug rod 2, and one side of the second clamping unit 5 is fixedly connected with a kit 4. The plug rod 2 extends into the interior of the kit 4, that is, the first clamping unit 1 and the second clamping unit 5 are fixedly connected through the plug rod 2 and the kit 4. At the same time, by controlling the depth of the plug rod 2 inserted into the kit 4, the distance between the first clamping unit 1 and the second clamping unit 5 is controlled, and the fixing requirements between different steel members are met in this way.

[0023] The first clamping unit 1 and the second clamping unit 5 are the same, and both include a base 13. The base 13 is a component with a cuboid contour. One side of the upper end of the base 13 is provided with a baffle 14. A clamping block 7 is slidably arranged on the upper end of the base 13. After the steel member is placed on the base 13, one side of it abuts against the baffle 14, and the other side is clamped by the moving clamping block 7 to realize the clamping and fixing of the steel member. The lower part of the clamping block 7 is threadedly engaged with a second screw 15. By rotating the second screw 15, the clamping block 7 threadedly connected with it moves to realize the operation of clamping or releasing.

[0024] The upper end of the kit 4 is threadedly connected with a first bolt 3, and the lower end of the first bolt 3 abuts against the insertion rod 2. That is, after the distance adjustment between the first clamping unit 1 and the second clamping unit 5 is completed, the first bolt 3 is tightened, and the lower end of the first bolt 3 abuts against the insertion rod 2 to achieve the fixation between the kit 4 and the insertion rod 2.

[0025] A T-shaped groove 8 is provided at the upper end of the base 13, and the T-shaped groove 8 is perpendicular to the baffle 14. The lower part of the clamping block 7 is slidably fitted inside the T-shaped groove 8. That is, the shape of the lower part of the clamping block 7 is adapted to the T-shaped groove 8, and at the same time, the T-shaped groove 8 is perpendicular to the baffle 14, so as to realize the sliding of the clamping block 7 in the direction facing the baffle 14.

[0026] One end of the second screw rod 15 is fixedly connected with a regular hexagon bayonet 11. By using tools such as a wrench to hold the regular hexagon bayonet 11, the second screw rod 15 can be rotated by the tool, realizing the setting of the position of the clamping block 7.

[0027] An opening 16 is provided on the lower side wall of the clamping block 7. Since most of the steel members used in the steel frame are steel plates, angle steels, channel steels, etc., the provided opening 16 can catch the edge of the steel member, improving the stability of the clamping.

[0028] A fixing plate 12 is provided on one side of the base 13, and one end of the second screw rod 15 passes through the fixing plate 12. That is, the fixing plate 12 is used for supporting the second screw rod 15. At the same time, the second screw rod 15 and the fixing plate 12 are rotatably connected. Through the support of the fixing plate 12, the second screw rod 15 is kept horizontal and can bear the axial force. A number of second bolts 6 are provided on the fixing plate 12, and the second bolts 6 are threadedly connected with the base 13. That is, through the second bolts 6, the fixing plate 12 is fixedly connected to the base 13.

[0029] Both sides of the upper end of the base 13 are rotatably connected with first screw rods 10. When not in use, the first screw rods 19 can be retracted and arranged side by side with the baffle 14. A pressure rod 9 and a nut 17 are provided on the first screw rod 10. The nut 17 is threadedly connected with the first screw rod 10 and is located above the pressure rod 9. When the height dimension of the clamped steel member is relatively large, there is a problem of unstable clamping when the clamping block 7 and the baffle 14 clamp its lower part. Therefore, the first screw rod 10 and the pressure rod 9 are provided. After the steel member is clamped, in order to improve the clamping stability, the first screw rod 10 is erected, and then the pressure rod 9 is sleeved on it, and the nut 17 is used to restrict the pressure rod 9 downward, so that the pressure rod 9 tightly abuts against the steel member.

[0030] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include the technical solutions composed of any combination of the above technical features.
