Description

Technical Field

[0001] The utility model relates to the technical field of screw rods, in particular to a special-shaped reinforcement screw rod. Background Art

[0002] The outer surface of the screw is a cylinder with a spiral groove or a cone with a conical spiral groove. The screw has different heads, and the head is called an external hexagonal screw. There are others, such as a large flat screw, an internal hexagonal screw, and so on.

[0003] During on-site construction, when encountering two planes of different materials, such as cast-in-place concrete and PC composite panels, it is difficult to maintain the two on the same plane, resulting in part of the plane protruding and the surfaces of different materials cannot be aligned.

[0004] To this end, we propose special-shaped reinforcement screws to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a special-shaped reinforcing screw rod to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solutions: a special-shaped reinforcing screw rod, comprising a mounting rod, two sets of connecting rods are welded on the surface of the mounting rod, and the surface of the connecting rod is provided with an adjusting nut, and a moving block is provided above the adjusting nut;

[0007] Two groups of support plates are fixedly connected to the surfaces of the moving blocks.

[0008] Preferably, the surface of the connecting rod is fixedly connected with a limiting plate, and the limiting plate is configured to be truncated cone-shaped.

[0009] Preferably, the erection rods and the connecting rods are both made of ammoniated steel.

[0010] Preferably, a thread matching the adjusting nut is formed on the surface of the connecting rod, and the moving block is movably connected to the adjusting nut.

[0011] Preferably, the support plate is configured as a long plate with a certain curvature.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the adjusting nut is turned upward, the moving block is also pushed to drive the support plate to move upward. During the displacement process, the support plate also moves the supported steel pipe and wood direction. The template is also erected on the wooden square. The limiting piece fixedly connected to the surface of the connecting rod plays a role in positioning and leveling. The bottom surface of the limiting piece is on the same horizontal plane as the bottom surface of the composite plate. When the template is fitted with the limiting piece fixedly connected to the surface of the connecting rod, the top surface of the template and the bottom surface of the composite plate are on the same horizontal plane.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2 The utility model provides a technical solution: a special-shaped reinforcement screw rod, including a setting rod 1. During on-site construction, after the pouring of concrete and the placement of the PC composite board are completed, a plurality of setting rods 1 are set between the concrete and the PC composite board. The setting rods 1 are parallel to the PC composite board and the concrete layer. At this time, the two groups of connecting rods 2 welded on the surface of the setting rod 1 are vertically downward.

[0019] For details, please refer to Figure 1-2 At this time, the adjusting nut 3 threaded on the surface of the connecting rod 2 is rotated, and the adjusting nut 3 moves up and down on the surface of the connecting rod 2. The adjusting nut 3 also drives the moving block 4 to move up and down while moving up and down. The surface of the moving block 4 is fixedly connected to the supporting plate 5, and the steel pipe is placed on the supporting platform formed by multiple supporting plates 5. Wooden squares can also be added to the steel pipe. When the adjusting nut 3 is rotated to move upward, it also pushes the moving block 4 to drive the supporting plate 5 to move upward. The supporting plate 5 also moves the supported steel pipe and wood in the process of displacement. The template is also erected on the wooden square. The limiting piece 6 fixedly connected to the surface of the connecting rod 2 plays a role of positioning and leveling. The bottom surface of the limiting piece 6 is in the same horizontal plane as the bottom surface of the superimposed plate. When the template is in contact with the limiting piece 6 fixedly connected to the surface of the connecting rod 2, the top surface of the template and the bottom surface of the superimposed plate are in the same horizontal plane.

[0020] Working principle: During on-site construction, after the pouring of concrete and the placement of PC composite panels are completed, multiple erection rods 1 are erected between the concrete and the PC composite panels. The erection rods 1 are parallel to the PC composite panels and the concrete layers. At this time, the two sets of connecting rods 2 welded on the surface of the erection rods 1 are vertically downward. At this time, the adjusting nuts 3 screwed on the surface of the connecting rods 2 are rotated, and the adjusting nuts 3 move up and down on the surface of the connecting rods 2. While the adjusting nuts 3 move up and down, they also drive the moving blocks 4 to move up and down. The surface of the moving blocks 4 is fixedly connected to the support plates 5. The steel pipes are placed on the support platform formed by the multiple support plates 5. Wooden squares can also be added to the steel pipes. While the adjusting nuts 3 are rotated to move upward, they also push the moving blocks 4. The movable block 4 drives the support plate 5 to move upward. The support plate 5 also moves the supported steel pipe and wood in the process of displacement. The template is also erected on the wood. The limiting piece 6 fixedly connected to the surface of the connecting rod 2 plays a role of positioning and leveling. The bottom surface of the limiting piece 6 is in the same horizontal plane as the bottom surface of the composite board. When the template is fitted with the limiting piece 6 fixedly connected to the surface of the connecting rod 2, the top surface of the template and the bottom surface of the composite board are in the same horizontal plane. This solves the problem that when encountering two planes of different materials during on-site construction, such as cast-in-place concrete and PC composite boards, it is difficult to maintain the two in the same plane, resulting in partial protrusion of the plane and the inability to align surfaces of different materials.
