[0034] Specifically, anchor bolt 1 includes bolt screw rod 101 and bolt head 102, positioning support 2 is connected with bolt screw rod 101, and specifically as shown in the figure, so that positioning support 2 can be unfolded or folded along the horizontal direction, and the welding of bolt head 102 and steel reinforcement framework is not affected. Figure 1

[0035] Positioning support 2 has two, two positioning supports 2 are installed along the vertical direction and are spaced apart, two positioning supports 2 are connected with bolt screw rod 101, and two positioning supports 2 are distributed along the upper and lower directions and are spaced apart, so as to improve the stability of the connection between four anchor bolt 1 and positioning support 2, ensure the parallel relationship between four anchor bolt 1, and avoid the situation that the top end and the bottom end of four anchor bolt 1 swing relative to each other.

[0036] First positioning column 204 is installed on second branch 202, so that when first branch 201 is rotated along the positive direction to abut against first positioning column 204, the included angle between first branch 201 and second branch 202 is a right angle, since the installation of four anchor bolt 1 is mostly suitable for square layout, when the included angle between first branch 201 and second branch 202 is a right angle, four anchor bolt 1 can form square distribution. ​

[0037] In the present application, the forward rotation refers to the first support rod 201 or the second support rod 202 rotates in the counterclockwise direction in the perspective view, and the reverse rotation refers to the first support rod 201 or the second support rod 202 rotates in the clockwise direction in the perspective view. The first support rod 201 rotates in the forward direction to abut against the first positioning column 204, which means that the positioning support 2 is in the folding state shown in the figure, and the first support rod 201 rotates counterclockwise to abut against the first positioning column 204, at which time the included angle between the first support rod 201 and the second support rod 202 is a right angle. Figure 6

[0038] The first support rod 201 and the second support rod 202 are of the same specification, and the first support rod 201 is provided with a first groove 205 corresponding to the first positioning column 204, so that when the first support rod 201 rotates in the reverse direction to abut against the first positioning column 204, the first positioning column 204 is located in the first groove 205.

[0039] Specifically, the first positioning column 204 is on the rotation track of the first groove 205, and when the first support rod 201 rotates clockwise to the state where the second support rod 202 is folded together, the first positioning column 204 is located in the first groove 205, so that the first support rod 201 and the second support rod 202 can be more closely fitted when folded, thereby reducing the size of the positioning support 2 after folding, so that the device can be folded when transported, saving space.

[0040] It should be noted that in addition to installing the first positioning column 204 on the second support rod 202 and machining the first groove 205 on the first support rod 201, a second positioning column 207 can also be installed on the first support rod 201, and a second groove 206 can be machined on the second support rod 202. When the first positioning column 204 is located in the first groove 205, the second positioning column 207 is located in the second groove 206, the first positioning column 204 is located at the top of the second support rod 202, and the second positioning column 207 is located at the bottom of the first support rod 201 (as shown in the figure), which increases the stability of the first support rod 201 and the second support rod 202 after rotating and unfolding. Figure 4

[0041] The shapes of the first groove 205 and the second groove 206 are both "√" shapes, as shown in the figures.

The long circular arc structures make the first positioning column 204 more easily enter the first groove 205, and the second positioning column 207 more easily enter the second groove 206, and the inner side walls of the short circular arc structures are respectively clamped with the outer side walls of the first positioning column 204 and the second positioning column 207, so that the first supporting rod 201 and the second supporting rod 202 can be clamped after the device is folded, avoiding the device from being automatically opened due to natural gravity or external force during transportation and taking, and improving the stability of the device after folding.

[0042] Embodiment 2

[0043] With reference to Figures 5-7 The utility model discloses a quick installation type anchor bolt assembly, and the difference between the embodiment and embodiment 1 lies in that the anchor bolt 1 is L type anchor bolt, the bolt screw rod 101 is long rod structure, and a section of external thread is processed on the top of long rod structure, the bolt head 102 is short rod structure, the bottom end of long rod structure is connected with one end of short rod structure, and the bolt screw rod 101 is perpendicular to the bolt head 102.

[0044] The axis of the bolt head 102 is parallel with the axis of the first supporting rod 201 or the second supporting rod 202, and specifically, the direction of the long side of the first supporting rod 201 and the second supporting rod 202 is the direction of the axis, and the bolt head 102 is in the direction of the extension line of the long side of the first supporting rod 201 or the second supporting rod 202, so that when the positioning support 2 is folded, the bolt heads 102 of the two anchor bolts 1 close to each other can also be closely attached together, thereby further reducing the flatness of the device after folding and reducing the space occupation.

[0045] Embodiment 3

[0046] With reference to Figures 8-10 The utility model discloses a quick installation type anchor bolt assembly, and the difference between the embodiment and embodiment 2 lies in that the first supporting rod 201 and the second supporting rod 202 are detachably connected with the bolt screw rod 101.

[0047] Specifically, the end of the positioning support 2 is the end of the first support rod 201 and the second support rod 202, and the C-shaped clamp 3 is installed at the end of the first support rod 201 and the second support rod 202. The C-shaped clamp 3 is an annular structure with one side opening, the opening size is smaller than the diameter of the bolt screw 101, and the whole is in the shape of C. The C-shaped clamp 3 has elasticity. In use, the bolt screw 101 enters the C-shaped clamp 3 through the opening, and the C-shaped clamp 3 clamps the bolt screw 101. In this way, the anchor bolt 1 and the positioning support 2 can be disassembled and stacked before use, which saves more space, reduces the restriction on the orientation of the bolt head 102, and can rotate the orientation of the bolt head 102 to the desired orientation position as needed during use.

[0048] The reinforcing ribs 103 can also be welded and fixed on the surface of the bolt screw 101. The reinforcing ribs 103 are also annular structures, and the reinforcing ribs 103 are arranged around the surface of the bolt screw 101. A plurality of reinforcing ribs 103 are distributed along the axial direction of the bolt screw 101. The distance between the adjacent two reinforcing ribs 103 is greater than the height of the C-shaped clamp 3. In use, the four C-shaped clamps 3 at the end of the positioning support 2 are clamped between two reinforcing ribs 103 at the same height. The reinforcing ribs have two effects. One is that two or more positioning supports 2 can be clamped and installed between reinforcing ribs 103 at different heights during use, so that the adjacent two positioning supports 2 are also spaced apart. The second is that the reinforcing ribs can effectively increase the contact area between the anchor bolt 1 and the concrete during pouring and fixing the anchor bolt 1, and improve the stability of the combination between the anchor bolt 1 and the concrete.

[0049] Working principle: The device is directly prefabricated in the prefabricated factory, and then transported to the construction site for use. During transportation, the device can fold the anchor bolt 1 and the positioning support 2 together, or disassemble and transport the anchor bolt 1 and the positioning support 2 separately according to needs. More devices can be stacked in the same transportation space.

[0050] In use, the positioning support 2 is clamped and fixed between two reinforcing ribs 103 at the same height position by the C-shaped clamp 3. The positioning support 2 is unfolded so that the first support rod 201 and the second support rod 202 are perpendicular to each other. Then, the bolt head 102 of two adjacent anchor bolts is welded on the steel reinforcement cage. In this way, the other two anchor bolts 1 can be automatically positioned at the predetermined position, thereby reducing the welding frequency and reducing the occupational hazards of construction personnel caused by electric welding operation.

[0051] During position review, the positions of only two anchor bolts 1 can be reviewed, or the positions of four anchor bolts 1 can be confirmed to meet the construction standard, thereby reducing the review frequency and improving the construction efficiency.

[0052] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical scope disclosed by the present application, and all of them should be covered within the protection scope of the present application.
