The end part of the screw rod extending out of the U-shaped bracket is provided with a straight rod vertical to the screw rod.

The utility model relates to an auxiliary construction tool for in curtain construction process, including U type support and relative two chucks of setting on U type support inner wall, a tip of a connecting rod of one of them chuck setting on U type support inner wall, another chuck setting is at the tip of wearing to establish the lead screw on offside U type support inner wall. The clamping distance between the two chucks can be changed by screwing one end of the screw rod extending out of the U-shaped bracket. The utility model discloses a two chucks are both sides mutually perpendicular's the steel sheet of bending, the medial surface of one of them straight flange of two chucks and the end connection of connecting rod or lead screw, and the lateral surface of this straight flange is the clamping face. The two chucks can rotate around an axis vertical to the clamping surface at the end part of the lead screw or the connecting rod. The utility model discloses in the curtain construction process, generally use in pairs, at first with the both sides of this anchor clamps two clamping faces grasp the perpendicular roof beam to another straight flange face that makes the chuck with wait to splice the bottom surface parallel and level of welding the crossbeam together with perpendicular roof beam, then place the crossbeam on the straight flange of two anchor clamps chucks, thereby carry out the crossbeam and erect the weldment work between the roof beam. The utility model discloses, the installation of being convenient for is dismantled, can effectual roughness and the elevation of guaranteeing the crossbeam, can not only improve the construction speed, guarantees construction quality, can also avoid the secondary to rework.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view of the usage state of the present invention.

In the figure: 1. a U-shaped bracket; 2. a connecting rod; 3. a chuck; 4. a lead screw; 5. a straight rod; 6. erecting a beam; 7. a cross member.

Detailed Description

As shown in fig. 1 and 2, the present invention includes a U-shaped bracket 1 and two chucks 3 arranged in pairs, wherein the two chucks 3 are respectively arranged on two inner walls of the U-shaped bracket 1, and the two chucks 3 are arranged relatively. A connecting rod 2 is arranged on one of the inner walls of the U-shaped bracket, the connecting rod 2 is vertical to the inner wall of the U-shaped bracket 1, and one clamping head 3 is arranged at the end part of the free end of the connecting rod 2. A lead screw 4 is arranged on the other inner wall of the U-shaped support 1 in a penetrating mode, the other chuck is arranged at the end portion of one end, located in the U-shaped support 1, of the lead screw 4, one end, extending out of the U-shaped support 1, of the lead screw 4 is a screwing end, the screwing end of the lead screw 4 is screwed, the distance between the two chucks 3 can be changed, and therefore clamping work is completed. In order to facilitate the screwing of the screw rod 4, the end of the screw rod 4 is further provided with a straight rod 5 perpendicular to the end, and the straight rod 5 serves as a handle.

The utility model discloses a two chucks 3 are made for the steel sheet of bending by both sides mutually perpendicular, the medial surface of one of them straight flange of chuck 3 and the end connection of connecting rod 2 or lead screw 4 that correspond, and the lateral surface of this straight flange is the clamping face. The clamping surfaces of the two clamping heads 3 are kept parallel, and the outer side surface of the other straight edge of the two clamping heads 3 is a supporting surface for supporting the cross beam 7. The utility model discloses a two chucks 3 can be around rotatory with clamping face vertically axis at connecting rod 2 or lead screw 4's tip to can adjust the holding surface that is used for supporting beam 7, with the accuracy of guaranteeing beam 7's position. As for how the two chucks 3 are rotatably connected at the end of the screw 4 and the connecting rod 2, respectively, the connection structure thereof is a common technical means and will not be described in detail.

When the clamp is used in practice, the clamp is often used in pairs, firstly, the two clamps are respectively clamped between two vertical beams 6 of a cross beam 7 to be welded, as shown in fig. 2, the supporting surface formed by the chucks 3 of the clamp is adjusted in the clamping process, so that the supporting surface formed by the chucks 3 of the two clamps and used for supporting the cross beam 7 is kept flush with the bottom surface of the cross beam 7 to be welded. Finally, the cross beam 7 to be welded is placed on the supporting surface formed by the joints 3 of the two fixtures, so that the welding work between the cross beam 7 and the vertical beam 6 is performed.
