Description

Technical Field

[0001] The utility model relates to the technical field of building components, in particular to a detachable anchoring structure for a small temporary building and a hardened ground. Background Art

[0002] In recent years, with the continuous development of prefabricated buildings, the number of small temporary structures such as exhibition halls, experience halls, and post stations has increased. These projects typically require hardened ground, and the site often needs to serve other functions after the temporary structure is moved, such as parking or sports venues.

[0003] Based on the above situation, there is a contradiction between the traditional connection method between buildings and foundations and the flexibility of prefabricated buildings. This is mainly manifested in:

[0004] 1. After the anchor bolts are connected to the structure, secondary pouring is usually required, which seriously affects the disassembly performance of the prefabricated building;

[0005] 2. The screw rod of the anchor bolt will protrude from the ground, which seriously limits the changes in the use function of the hardened ground. Utility Model Content

[0006] The purpose of the utility model is to provide a detachable anchoring structure between a small temporary building and a hardened ground to solve the above-mentioned problem. The fully detachable approach is adopted to ensure that the hardened ground is restored to its original function after the temporary building is moved without affecting the surface flatness of the hardened ground.

[0007] Technical solution: The utility model provides a detachable anchoring structure between a small temporary building and a hardened ground, including: a hardened ground, a mechanical anchor bolt, a threaded sleeve, a secondary pouring layer, and an anchor bolt. The hardened ground is the hard surface layer of the construction site. Anchor holes and secondary pouring holes are dug under the hardened ground. The secondary pouring hole is directly through the ground surface and has an inner diameter larger than the inner diameter of the anchor hole. The mechanical anchor bolt is driven into the hardened ground and set in the anchor hole. The bolt portion above the mechanical anchor bolt protrudes from the anchor hole and enters the secondary pouring hole. The threaded sleeve is sleeved on the mechanical anchor bolt. The secondary pouring layer is poured in the secondary pouring hole, filling the secondary pouring hole and fixing the threaded sleeve. The anchor bolt is set in the threaded sleeve. The secondary pouring process is placed before the installation of the structural components, eliminating the bonding between the secondary pouring and the structural components but retaining the vertical support force. The screw portion of the anchor bolt can be disassembled. After the anchor bolt is disassembled, the hardened ground is flat and has no protrusions. All components are implanted after the hardened ground construction is completed, and there is no need to pre-embed them in advance.

[0008] Furthermore, in the aforementioned detachable anchoring structure for a small temporary structure to hardened ground, the anchor hole and the secondary pouring hole are on the same center line. The anchor hole is drilled downward from the center of the bottom of the secondary pouring hole, and a mechanical anchor bolt is inserted and tightened to generate an anchoring force. This provides horizontal positioning for the threaded sleeve and also provides a portion of the vertical anchoring force for the threaded sleeve.

[0009] Furthermore, in the above-mentioned detachable anchoring structure between a small temporary building and hardened ground, the length of the bolt portion above the mechanical anchor is 1 / 2 the length of the threaded sleeve.

[0010] Furthermore, in the aforementioned detachable anchoring structure for a small temporary building and hardened ground, the threaded sleeve is adjusted in height before the secondary pouring so that the secondary pouring layer and the threaded sleeve are in the same horizontal plane and slightly higher than the highest point of the hardened ground surface. This can correct for possible construction errors in the original site hardened ground surface 1.

[0011] Furthermore, in the above-mentioned detachable anchoring structure between a small temporary building and hardened ground, the secondary pouring layer is cast using cement mortar.

[0012] Furthermore, in the above-mentioned detachable anchoring structure between a small temporary building and a hardened ground, the maximum height of the threaded sleeve after being inserted into the mechanical anchor bolt should be greater than or equal to the surface height of the hardened ground 1.

[0013] It can be seen from the above technical solution that the utility model has the following beneficial effects: the detachable anchoring structure of a small temporary building and a hardened ground described in the utility model provides anchoring of the temporary building and the hardened ground, and adopts a completely detachable approach to ensure that the hardened ground is restored to its original function after the temporary building is moved, without affecting the surface flatness of the hardened ground. Moreover, the detachable anchoring structure does not require pre-embedded components during the construction of the hardened ground, and the completely later implantation method is more in line with the actual situation of temporary construction projects.
