Description

Technical Field

[0001] The utility model relates to the technical field of static load settlement detection, in particular to a reference device for static load settlement detection. Background Art

[0002] Static load test refers to a test method in which vertical pressure, vertical upward pull or horizontal thrust is applied step by step to the top of the pile, and the settlement, upward pull or horizontal displacement of the pile top over time is observed to determine the corresponding single pile vertical compressive bearing capacity, single pile vertical pull-out bearing capacity or single pile horizontal bearing capacity. Static load test is currently the most accurate, reliable and most common bearing capacity test method in foundation testing. The existing benchmark devices for static load settlement testing can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] Most of the widely used reference devices for static load settlement detection on the market have bracket rods installed on both sides of the reference beam, and the bracket rods are inserted into the ground to fix the reference beam. In order to facilitate the insertion of the bracket rod into the ground, the bottom end of the bracket rod is usually set to be sharper, which leads to the bottom end of the bracket rod being prone to collision with external objects during equipment transportation, which not only easily causes damage to the external objects, but also once the tip of the bracket rod is deformed, it cannot be used anymore. For this reason, we propose a reference device for static load settlement detection to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a reference device for static load settlement detection to solve the problems raised in the above background technology.

[0006] As a further preferred embodiment of the present technical solution, the movable positioning assembly includes a connecting bracket, a sliding sleeve, a sliding rod, a positioning pressure block, a handle, and a return spring. A connecting bracket is fixed to the outer wall of the side end of the mounting seat, a sliding sleeve is fixed to the top of the connecting bracket, two groups of sliding rods are arranged on both sides of the sliding sleeve, positioning pressure blocks are fixed to the bottom ends of the two groups of sliding rods, handles are fixed to the top ends of the two groups of sliding rods, and return springs are wound around the outsides of the two groups of sliding rods.

[0008] As a further preferred embodiment of the present technical solution, the outer wall of the threaded column is provided with a plurality of groups of anti-slip grooves at equal intervals along the axis of the threaded column.

[0009] As a further preferred embodiment of the present technical solution, the outer walls of the two groups of sliding rods are fully fitted with the inner wall of the sliding sleeve, and the two groups of sliding rods are slidably connected to the sliding sleeve.

[0010] As a further preferred embodiment of the present technical solution, a rubber gasket is glued to the outer wall of the bottom end of the positioning pressing block.

[0012] The utility model provides a reference device for static load settlement detection, which has the following beneficial effects:

[0013] 1. The utility model installs two groups of bracket rods at the bottom end of the mounting base, and provides a sheath that can slide up and down on the outside of the bracket rod. The threaded sleeve can be rotated to allow the threaded sleeve to rotate outside the threaded column, so that the threaded sleeve can drive the two groups of sheaths to move downward along the bracket rod under the action of the thread, and the two groups of sheaths are moved to the bottom ends of the two groups of bracket rods to form protection for the bottom tips of the two groups of bracket rods, thereby effectively preventing the bottom tips of the bracket rods from being damaged by the outside during transportation, and also avoiding the tip of the bracket rod from being damaged by impact, thereby increasing the service life of the bracket rod.

[0014] 2. The utility model installs a liftable positioning block on the top of the mounting seat. After the end of the reference beam is inserted into the positioning groove on the mounting seat, the reset springs outside the two sets of slide bars can release their elastic force, so that the positioning block can drive the two sets of slide bars to move downward along the sliding sleeve under the elastic force of the two sets of reset springs. When the positioning block moves to the outside of the reference beam, the positioning block can quickly form an active positioning component for the reference beam, thereby avoiding the shaking of the reference beam during the measurement process and improving the stability of the device when in use.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 4 As shown, in the present embodiment, a reference device for static load settlement detection includes a mounting seat 1, a positioning groove 2 is provided at the top of the mounting seat 1, a reference beam 3 is placed in the positioning groove 2, a movable positioning component is provided at the top of the mounting seat 1, two groups of bracket plug rods 4 are fixed at the bottom of the mounting seat 1, both groups of bracket plug rods 4 are provided with sheaths 5 on the outside, a positioning block 6 is provided between the two groups of sheaths 5, a threaded sleeve 7 is rotatably connected to the top of the positioning block 6, a threaded column 8 is fixed to the middle of the bottom end of the mounting seat 1, and the threaded sleeve 7 is threadedly connected to the threaded column 8.

[0022] After the two groups of bracket rods 4 are installed at the bottom end of the mounting base 1, and a sheath 5 that can slide up and down is arranged on the outside of the bracket rod 4, the threaded sleeve 7 can be rotated to allow the threaded sleeve 7 to rotate outside the threaded column 8, so that the threaded sleeve 7 can drive the two groups of sheaths 5 to move downward along the bracket rod 4 under the action of the thread, so that the two groups of sheaths 5 move to the bottom ends of the two groups of bracket rods 4, forming protection for the bottom tips of the two groups of bracket rods 4, thereby effectively preventing the bottom tips of the bracket rods 4 from being damaged by the outside during transportation, and also avoiding the tip of the bracket rod 4 from being damaged by impact, thereby improving the service life of the bracket rod 4. After the two groups of bracket rods 4 are inserted into the ground, the threaded sleeve 7 can also be rotated to allow the positioning block 6 to drive the two groups of sheaths 5 to move to the ground, and the insertion depth of the bracket rod 4 can be judged by the distance between the bottom end of the positioning block 6 and the bottom end of the bracket rod 4.

[0023] In other embodiments, the movable positioning assembly includes a connecting bracket 9, a sliding sleeve 10, a sliding rod 11, a positioning pressure block 12, a handle 13, and a reset spring 14. The connecting bracket 9 is fixed to the outer wall of the side end of the mounting seat 1, and the sliding sleeve 10 is fixed to the top of the connecting bracket 9. Two groups of sliding rods 11 are arranged on both sides of the sliding sleeve 10. The positioning pressure block 12 is fixed to the bottom end of the two groups of sliding rods 11, and the handle 13 is fixed to the top end of the two groups of sliding rods 11. The reset spring 14 is wound around the outside of the two groups of sliding rods 11.

[0024] By installing a liftable positioning block 12 on the top of the mounting seat 1, when the reference beam 3 needs to be installed, the handle 13 can be pulled upward to allow the two groups of slide bars 11 to drive the positioning block 12 to move upward along the sliding sleeve 10. The return springs 14 outside the two groups of slide bars 11 are squeezed and deformed to accumulate force by the positioning block 12. When the positioning block 12 moves upward a suitable distance, the end of the reference beam 3 is inserted into the positioning groove 2 on the mounting seat 1. Then, the pulling force on the handle 13 is released to allow the return springs 14 outside the two groups of slide bars 11 to release the elastic force, so that the positioning block 12 can drive the two groups of slide bars 11 to move downward along the sliding sleeve 10 under the elastic force of the two groups of return springs 14. When the positioning block 12 moves to the outside of the reference beam 3, the positioning block 12 can quickly form an active positioning component for the reference beam 3, thereby avoiding the shaking of the reference beam 3 during the measurement process and improving the stability of the device during use.

[0025] In other embodiments, the outer wall of the bottom end of the positioning block 6 and the outer wall of the bottom end of the sheath 5 are located in the same horizontal plane;

[0026] With this design, after the two sets of support rods 4 are inserted into the ground, the positioning blocks 6 can drive the two sets of sheaths 5 to move to the ground, thereby increasing the contact area between the device and the ground and preventing the support rods 4 from sinking during the measurement process.

[0027] In other embodiments, the outer wall of the threaded column 8 is provided with a plurality of anti-slip grooves at equal intervals along the axis of the threaded column 8;

[0028] Through this design, when the threaded column 8 needs to be rotated, the hand can be effectively prevented from slipping off the outside of the threaded column 8, thereby facilitating the effective rotation of the threaded column 8.

[0029] In other embodiments, the outer walls of the two sets of sliding rods 11 are fully fitted with the inner wall of the sliding sleeve 10, and the two sets of sliding rods 11 are slidably connected with the sliding sleeve 10;

[0030] With this design, when the two groups of slide bars 11 move up and down in the slide sleeve 10 , it is possible to effectively prevent the two groups of slide bars 11 from shaking during the movement, thereby improving the stability of the positioning pressing block 12 during movement.

[0031] In other embodiments, a rubber gasket is glued to the outer wall of the bottom end of the positioning block 12;

[0032] Through this design, the friction force between the positioning pressing block 12 and the reference beam 3 can be effectively increased, thereby improving the positioning effect of the positioning pressing block 12 on the reference beam 3.

[0033] In other embodiments, the two ends of the return spring 14 are respectively connected to the outer wall of the positioning block 12 and the outer wall of the bottom end of the sliding sleeve 10, and the positioning block 12 is elastically connected to the outer wall of the bottom end of the sliding sleeve 10 through the return spring 14;

[0034] Through this design, the return springs 14 outside the two sets of slide bars 11 can continuously apply downward elastic force to the positioning block 12, so that the positioning block 12 can quickly move to the surface of the reference beam 3 in the positioning groove 2, forming a stable clamping effect on the reference beam 3.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
