Description

Technical Field

[0001] The utility model relates to the technical field of building prefabricated component testing, in particular to a rotatable prefabricated anchor pile cap. Background Art

[0002] The pile body is a commonly used load-bearing component in construction. In order to ensure that the load-bearing capacity of the pile body meets the design requirements, the pile body needs to be subjected to a static load test after the pile body construction is completed. The test equipment and steel beams of the static load test are placed on the top of the anchor piles around the pile body.

[0003] During the static load test, the test equipment and steel beams are required to be installed at a height of more than 2m above the ground. Therefore, there are certain requirements for the height of the top of the anchor pile above the ground, which leads to a high construction height of the reinforced concrete at the top of the anchor pile, high construction costs, and long construction hours. Therefore, it is necessary to provide a recyclable prefabricated anchor pile cap that can solve the problem of high construction costs and long construction hours caused by the high construction height of the top of the anchor pile in the prior art.

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 4 A rotatable prefabricated anchor pile cap, the prefabricated anchor pile cap 1 comprises a pile cap body 4 and a pile cap foot 5 formed at the bottom of the pile cap body 4; the top surface of the anchor pile 2 is located between the ground 3 and the shelving height, the cross-sectional size of the pile cap foot 5 is larger than the cross-sectional size of the top of the anchor pile, a lower surface recessed portion 7 is formed in the pile cap foot 5, and the cross-sectional size of the lower surface recessed portion 7 is slightly larger than the top cross-sectional size of the anchor pile 2 and the top cross-sectional size of the pile cap body 4, so that the first prefabricated anchor pile cap 1 is sleeved on the top of the anchor pile 2 through the lower surface recessed portion 7, and the previous prefabricated anchor pile cap 1 is sleeved on the top of the pile cap body 4 of the next prefabricated anchor pile cap 1 through the lower surface recessed portion 7, and several prefabricated anchor pile caps 1 are stacked upward in sequence to the shelving height, and the test equipment and steel beams are shelved on the top of the pile cap body 4 of the last prefabricated anchor pile cap 1.

[0023] The pile cap body 4 and the pile cap foot 5 can be prefabricated with concrete to form a prefabricated anchor pile cap 1. According to the pile diameter of the anchor pile (generally 600mm, 650mm, 700mm, 750mm, 800mm, 850mm and 900mm) and the required stacking height, i.e., the placement height of the test equipment and steel beam (generally 3 meters above the ground), the prefabricated anchor pile cap 1 is modularly manufactured, which is easy to prefabricate. The top surface of the pile cap body 4 can be set as a plane structure to facilitate the placement of the test equipment and steel beams, and can also be made into a desired shape according to actual placement requirements.

[0024] By setting the lower surface recessed portion 7, the pile cap foot 5 can be sleeved on the top of the anchor pile 2 or on the top of the pile cap body 4 of the next prefabricated anchor pile cap 1, so as to improve the stacking stability of the prefabricated anchor pile cap 1 and prevent it from tilting or falling off. The depth of the lower surface recessed portion 7 can be adaptively adjusted according to the actual stacking requirements to ensure the sleeve reliability of the two adjacent prefabricated anchor pile caps 1 and the prefabricated anchor pile cap 1 and the top of the anchor pile, so that it will not tilt or fall off during use. It is only necessary to construct the top of the anchor pile 2 to be slightly higher than the ground 3, and the protruding part can meet the stable installation of the prefabricated anchor pile cap 1, which reduces the construction cost, the amount of consumables used, and the construction time.

[0025] The top of the anchor pile 2 is raised to the required shelf height by the stacked prefabricated anchor pile caps 1 for supporting test equipment and steel beams. The stacked prefabricated anchor pile caps 1 are easy to assemble and disassemble and have a high turnover rate. There is no need to construct the reinforced concrete on the top of the anchor pile 2 to the required shelf height.

[0026] Please see attached Figure 2 and attached Figure 3The top of the pile cap body 4 is formed with an upper surface recessed portion 6, and a lifting handle 8 is embedded in the upper surface recessed portion 6.

[0027] Preferably, the lifting handle 8 can be made of steel bars, so that it can be embedded in the upper surface recess 6 when the concrete of the precast anchor pile cap 1 is cast. By setting the lifting handle 8, it can be connected to the hook of the lifting equipment, which is convenient for efficient disassembly and assembly of the precast anchor pile cap 1 and improves the turnover rate.

[0028] Please see attached Figure 2 and attached Figure 3 The two ends of the lifting handle 8 are anchored in the concrete of the pile cap body 4. The lifting handle 8 has high installation stability and can reliably bear the weight of the prefabricated anchor pile cap 1 during lifting. The top surface of the lifting handle 8 does not exceed the top surface of the pile cap body 4, and does not affect the stacking arrangement of the prefabricated anchor pile cap 1.

[0029] Please see attached Figure 1 and attached Figure 2 The pile cap body 4 and the pile cap foot 5 are cast into an integrated structure by concrete.

[0030] During the process of casting the pile cap body 4 and the pile cap foot 5 into the precast anchor pile cap 1, an upper surface recessed portion 6 is simultaneously reserved at the top of the precast anchor pile cap 1, and a lower surface recessed portion 7 is simultaneously reserved at the bottom of the precast anchor pile cap 1. The precast anchor pile cap 1 is integrally formed, has high structural strength, long service life, and improves turnover rate.

[0031] Please see attached Figure 3 and attached Figure 4 The pile cap body 4 and the pile cap foot 5 are cylindrical structures, and the diameter of the pile cap body 4 is consistent with the top diameter of the anchor pile 2, and the diameter of the pile cap foot 5 is larger than the diameter of the pile cap body 4.

[0032] Usually the anchor pile 2 is cylindrical, and the pile cap body 4 can be designed to be cylindrical in the same shape as the top of the anchor pile 2, thereby ensuring the vertical force stability and uniformity, and improving the safety and test accuracy of the pile static load test.

[0033] Please see attached Figure 1 The pile cap body 4 and the pile cap foot 5 are coaxially arranged with the anchor pile 2 to ensure vertical force transmission and further improve the vertical force stability and uniformity.

[0034] Please see attached Figure 1 To Attachment Figure 4 The method of using the utility model in the pile static load test is:

[0035] The first prefabricated anchor pile cap 1 is coaxially sleeved on the top of the anchor pile 2 slightly above the ground 3 through the lower surface recessed portion 7, and multiple prefabricated anchor pile caps 1 are stacked in sequence from bottom to top according to the test equipment and the placement height of the steel beam. When stacking the prefabricated anchor pile caps 1, the previous prefabricated anchor pile cap 1 is coaxially sleeved on the pile cap body 4 of the next prefabricated anchor pile cap 1 through the lower surface recessed portion 7, so that the top of the last prefabricated anchor pile cap 1 is stacked to the required placement height.

[0036] The anchor piles required around the pile body are stacked in the same way to form prefabricated anchor pile caps 1 to a specified height, and then the test equipment and steel beams are placed on the top of the last prefabricated anchor pile cap 1, and the pile body can be subjected to a static load test through the test equipment.

[0037] After the test is completed, the prefabricated anchor pile caps 1 can be removed by lifting them from top to bottom.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
