TECHNICAL FIELD
[0001] The utility model relates to the technical field of sand box device for anchorage test, especially a static load anchorage test safe and durable sand box. BACKGROUND
[0002] With the development of engineering technology, prestressed concrete has been widely used, and plays an important role in bridge construction. In the process of applying prestress to prestressed concrete structure, whether it is temporary anchorage of prestressed tendon by pretensioning method or permanent anchorage of prestressed tendon by post-tensioning method, anchor device is needed, and anchor device is one of the key factors to ensure the safety of prestressed concrete structure. Static load anchorage performance test of anchor device is the most important test to detect the quality of anchor device, which can comprehensively reflect the hardness, strength, anchorage capacity and other performances of anchor plate.
[0003] In the process of carrying out static load anchorage performance test, the clamping piece of anchorage steel strand and anchor device will often be ejected when the steel strand breaks, and the kinetic energy of the clamping piece is huge when it is ejected, which will cause great damage to the objects on both sides of the testing machine. Therefore, when carrying out related detection, a sand box is placed on both sides of the testing machine to absorb the energy of the clamping piece and avoid damage to personnel and equipment.
[0004] The front part of the conventional sand box is a wooden board (to avoid excessive hardness and cause safety hazards when the clamping piece rebounds to the side after colliding with it), and the other five surfaces are steel plates. The upper steel plate is mechanically connected with the intersecting surface steel plate, and the other surfaces are integrally welded. Sand or sand bags are placed inside. It is more difficult to replace the wooden board after the front wooden board is damaged. If the wooden board is replaced, the sand in the sand box needs to be cleaned first, which is time-consuming and labor-intensive, greatly wasting manpower and affecting work efficiency.

[0006] The utility model adopts the technical scheme that a static load anchorage test safe and durable sand box comprises a box body, front and rear clamping grooves are arranged on the box body, the front clamping groove is located at the front end of the box body, a panel is inserted into the front clamping groove, and a baffle is inserted into the rear clamping groove.
[0007] By adopting the above technical scheme, the panel is soft-connected with the other surfaces through the front clamping groove, which is convenient to extract when replacing the panel, saves time, and improves efficiency.
[0008] A buffer sand box is slidably inserted into the middle of the front and rear clamping grooves in the box body, a plurality of sand bag cabinets are arranged in the buffer sand box, and sand bags are placed in the sand bag cabinets.
[0009] By adopting the technical scheme, the impact force borne by the baffle can be reduced, and the kinetic energy of the clamping piece is reduced again when the clamping piece rebounds after impacting the baffle, so that the clamping piece can be ensured to stay in the buffer sand box after rebounding, and a secondary breakage of the panel to cause a security risk to the outside can be avoided. Meanwhile, the buffer sand box is introduced to be pullable, and a plurality of sand bags (for example, strip-shaped small sand bags) are introduced into the buffer sand box, so that the low efficiency of cleaning the scattered sand and the trouble of replacing the whole large sand bag by multiple people can be avoided, and one person can quickly complete the cleaning and replacement, so that the efficiency is improved while the labor is saved.
[0010] The cavity at the rear end of the rear clamping groove is filled with protective sand;
[0011] The baffle comprises a fluid sleeve, and non-Newtonian fluid (such as D3O) is arranged in the fluid sleeve. By introducing the non-Newtonian fluid into the baffle, the baffle can be quickly hardened when impacted by the clamping piece, a strong protective layer is formed, the baffle is protected from being penetrated by the clamping piece, the impact force of the clamping piece conducted by the baffle is absorbed by the protective sand behind the baffle, the baffle is prevented from being broken in a brittle manner, and the use durability is improved.
[0012] Further, the front clamping groove and the rear clamping groove are vertically arranged.
[0013] Further, the upper end of the buffer sand box is provided with a plurality of sand bag replacement openings corresponding to the sand bag box cabinet.
[0014] Further, the buffer sand box is slidably inserted into the box body through the guide rail pre-installed on the box body, and a push-pull handle is installed on the side wall of the buffer sand box, so that the buffer sand box can be conveniently assembled and disassembled.
[0015] Further, the bottom of the box body is provided with a driving wheel with a brake, so that the sand box can be moved during the preparation stage of the static load anchoring test, and the brake is in a braking state when the sand box is at rest, so that the sand box is stable.
[0016] The static load anchoring test safety durable sand box has the following beneficial effects:
[0017] 1. The baffle with the built-in non-Newtonian fluid separates the sand box into two parts, the baffle is quickly hardened when impacted by the clamping piece, a strong protective layer is formed, the baffle is protected from being penetrated by the clamping piece, the impact force of the clamping piece conducted by the baffle is absorbed by the protective sand behind the baffle, the baffle is prevented from being broken in a brittle manner, and the use durability is improved;
[0018] 2. When the panel is broken by the clamping piece, only the sand bags in the buffer sand box need to be cleaned and replaced, and the whole sand in the traditional sand box does not need to be cleaned, so that the efficiency and the convenience of replacement work are greatly improved;
[0019] 3. At the same time by introducing the front slot, the panel is connected with other surfaces of the sandbox body, when replacing the panel, it is convenient to extract, saves time and improves efficiency. BRIEF DESCRIPTION OF DRAWINGS
