Description

Technical Field

[0001] The utility model relates to but is not limited to the technical field of building construction, and in particular to a tool for installing and positioning a cast-in-place pile reinforcement cage. Background Art

[0002] During the on-site connection of the steel cage segments, the lower steel cage needs to be temporarily supported to facilitate the construction of the steel cage segment connection and control the pile top elevation. To ensure the connection of the steel cage, a steel cage wellhead support is set at the hole of the pile foundation to facilitate the construction of the steel cage segment connection and control the pile top elevation.

[0003] For example, the Chinese patent publication number CN219825266U discloses a bored pile reinforcement cage installation positioning device, which directly places the base at the bored pile hole and hooks the reinforcement cage through the limiting protrusion. The base is not fixed on the ground or the hole wall, and the base will be displaced due to external force, affecting the installation of the reinforcement cage. Therefore, a bored pile reinforcement cage installation positioning tool with better stability is designed. Utility Model Content

DETAILED DESCRIPTION

[0026] like Figure 1-4 As shown, the utility model provides a cast-in-place pile reinforcement cage installation positioning tool, including a base assembly 100, the base assembly 100 includes four support rods 101, four reinforcement rods 102 and a limit block 103, the ends of the four support rods 101 are welded into a support frame, the four reinforcement rods 102 are arranged on the inner side of the support frame, and the limit block 103 is fixed on the surface of the support rod 101;

[0027] A positioning rod 200, the positioning rod 200 passes through the interior of the limiting block 103, and a hook portion 201 is provided at the front end of the positioning rod 200;

[0028] The reinforcement component 300 is arranged at the four bottom corners of the support frame. The reinforcement component 300 includes a connecting block 301, a fixed block 302, an insertion rod 303, a bottom block 304 and a ground insertion column 306. The fixed block 302 is fixedly arranged at the bottom of the connecting block 301, the insertion rod 303 is arranged on the outside of the fixed block 302, the bottom block 304 is fixed to the bottom end of the insertion rod 303, and the ground insertion column 306 passes through the bottom block 304.

[0029] Furthermore, in the present embodiment, the connecting block 301 is designed as a hollow cylinder, and a connecting column plugged into the connecting block 301 is provided at the bottom of the support rod 101, and a fastener 305 is provided between the connecting column and the connecting block 301. The fastener 305 passes through the connecting block 301 and is threadedly engaged with the connecting column. The reinforcing component 300 is installed by inserting the connecting column into the connecting block 301, and the fastener 305 passes through the connecting block 301 to fix the connection between the connecting column and the connecting block 301, thereby realizing the connection between the reinforcing component 300 and the base component 100.

[0030] In this embodiment, at least three insertion rods 303 are arranged on the outer side of the fixed block 302. The three insertion rods 303 are obliquely arranged on the outer side of the fixed block 302 and are connected to the fixed block 302 with screws. The oblique design of the insertion rods 303 increases the contact area between the base and the ground. The screws facilitate the disassembly and assembly of the insertion rods 303. The insertion rods 303 can be left in the ground or pulled out according to needs.

[0031] In this embodiment, two ground plugs 306 form a group. The ground plugs 306 in the same group cross and penetrate the bottom block 304 in an X-shaped design. At least two groups are arranged on the bottom block 304. The ground plugs 306 are conical in design. The conical design of the ground plugs 306 increases the friction points between the insertion rod 303 and the ground, thereby improving the firmness of the insertion into the ground.

[0032] In this embodiment, a through hole 308 is opened near the upper end of the ground plug 306, and a baffle 307 is fixed to the outer side of the upper end of the ground plug 306, and the baffle 307 is located below the through hole 308. The ground plug 306 is threadedly engaged with the bottom block 304, and the baffle 307 is blocked at the upper end of the ground plug 306 to prevent the ground plug 306 from completely passing through the bottom block 304 and separating from the bottom block 304. In addition, a cross bar can be set between the ground plugs 306 in the same group through the through hole 308, and the two ends of the cross bar are respectively threadedly engaged with the through holes 308 of the two ground plugs 306 to form a stable structure.

[0033] In this embodiment, the inner sides of adjacent support rods 101 are screwed together with a reinforcement rod 102, and the connection between adjacent support rods 101 is reinforced by a reinforcement plate. A damping plate 104 is fixed to the upper surface of the reinforcement rod 102, and a piston rod 105 and a spring 106 are provided on the upper surface of the damping plate 104, and the spring 106 surrounds the outer side of the piston rod 105.

[0034] In this embodiment, damping plates 104 are provided at both ends of the piston rod 105, and the damping plates 104 are fixedly connected to the ends of the piston rod 105 and the spring 106 respectively. The piston rod 105 and the spring 106 disperse the force acting on the damping plate 104 to reduce the dynamic response of the structure.

[0035] In this embodiment, the positioning rod 200 is slidably connected to the limit block 103, and a limit slot 107 is provided at the upper end of the limit block 103. The limit slot 107 is screwed to the positioning rod 200. The screw passes through the limit slot 107 to limit the positioning rod 200, and the screw is limited by the limit block 103.

[0036] Specifically, according to the size and installation position of the base assembly 100, the reinforcement assembly 300 is inserted into the ground in advance, the bottom ground plug 306 is inserted into contact with the ground first, and then the plug rod 303 is inserted into the ground. The insertion angle of the plug rod 303 is adjustable, and the angle of the plug rod 303 can be fixed by screws, and then the base assembly 100 is laid at the hole of the cast-in-place pile, and the base assembly 100 is connected to the reinforcement assembly 300 through the connecting block 301 to complete the installation of the base assembly 100;

[0037] When positioning the steel cage, adjust the position of the positioning rod 200 in the limit block 103 according to the size of the steel cage, push the positioning rod 200 until the hook 201 of the positioning rod 200 is hooked on the steel bars of the steel cage, stop pushing, and fix the position of the positioning rod 200 by passing the screw through the limit slot 107 at the upper end of the limit block 103 to achieve the positioning of the steel cage;

[0038] Taking into account that the positioning rod 200 needs to bear the steel cage, in order to improve the supporting stability of the positioning rod 200, a shock-absorbing structure is arranged between the bottom of the positioning rod 200 and the reinforcement rod 102 on the inner side of the support rod 101. The height of the shock-absorbing structure is adapted to the distance between the positioning rod 200 and the reinforcement rod 102. The damping plate 104 at the bottom is fixed on the reinforcement rod 102, and the damping plate 104 at the upper end is tightly attached to the bottom of the positioning rod 200.
