Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a fully prefabricated foundation. Background Technique

[0002] The fully prefabricated foundation refers to the foundation part in the fully prefabricated concrete structure, which is assembled by prefabricated components through reliable connection methods. This structural system includes assembled monolithic concrete structures and fully assembled concrete structures, etc. Among them, the PC components of the fully prefabricated concrete structure are mainly formed into a whole through dry connections (such as bolt connections, welding, etc.).

[0003] The application of the fully prefabricated foundation reflects the general characteristics of prefabricated buildings, that is, components are produced in a standardized manner in the factory and then transported to the construction site for rapid assembly. Compared with the traditional on-site casting method, this construction method can significantly improve the construction efficiency, reduce construction waste and environmental pollution, and at the same time can also improve the quality and safety of the building. The fully prefabricated foundation is an important part of prefabricated buildings. Together with other prefabricated components, it constitutes the skeleton and foundation of the entire building through reliable connection methods.

[0004] During the installation process of the fully prefabricated foundation, if the construction is improper or there are technical problems, the foundation may tilt. For example, during the installation process of prefabricated components, if the hoisting and positioning are inaccurate, or there are problems with verticality and flatness, it may cause the foundation to tilt. In addition, if the prefabricated components are damaged during transportation and hoisting, such as the surface of the board cracking or even breaking, it will also cause the foundation to be unstable and increase the risk of tilting. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fully prefabricated foundation to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0011] Bevels are provided around the top of the precast concrete slab, and the bevels can increase the contact area with the soil layer to improve the stability of the precast concrete slab;

[0012] Grooves are vertically provided downward on the bevels, and the grooves and the connecting rods can cooperate with each other.

[0013] As a further solution of the present utility model:

[0014] A slotted opening is provided at the top of the connecting rod. When the connecting rod is buried in the soil layer, the soil layer will increase the difficulty of the upward movement of the connecting rod through the slotted opening.

[0015] As a further solution of the present utility model:

[0016] An extrusion surface is provided at the bottom of the connecting rod, and the extrusion surface is mutually attached to the bevel;

[0017] When the connecting rod moves towards the column, the connecting rod will push the bevel through the extrusion surface, so that the precast concrete slab has a tendency to move downward.

[0018] As a further solution of the present utility model:

[0019] One end of the connecting rod is located inside the groove, and an inclined surface is provided at one end of the connecting rod;

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] In addition, the elements in the present utility model are referred to as "fixed to" or "disposed on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0035] Please refer to Figures 1 - 6 In the embodiment of the present utility model, a fully prefabricated precast foundation includes a precast concrete slab 1, a column 2, and a plurality of connecting rods 3. The column 2 is fixedly arranged on the top of the precast concrete slab 1, and the plurality of connecting rods 3 can all be assembled and connected with the precast concrete slab 1.

[0036] Two adjacent precast concrete slabs 1 can be connected by the connecting rod 3. When one of the precast concrete slabs 1 tilts, the other precast concrete slab 1 can be made to have a downward trend through the connecting rod 3.

[0037] The horizontal cross-sectional area of the column 2 is smaller than that of the precast concrete slab 1, and a steel beam 4 is arranged at the top of the column 2.

[0038] In this solution, the adjacent two precast concrete slabs 1 are connected by the arranged connecting rod 3. When one of the precast concrete slabs 1 tilts, the other precast concrete slab 1 can be made to have a downward trend by using the connecting rod 3 to ensure the stability of the other precast concrete slab 1. At the same time, the reaction force of the connecting rod 3 is used to increase the difficulty of tilting the tilted precast concrete slab 1, thereby ensuring the stability and safety of the building structure. Among them, the column 2 and the steel beam 4 are used to support and connect the building steel structure.

[0039] As a further solution of the present utility model, inclined surfaces 101 are arranged around the top of the precast concrete slab 1. The inclined surfaces 101 can increase the contact area with the soil layer to improve the stability of the precast concrete slab 1.

[0040] A groove 102 is arranged vertically downward on the inclined surface 101, and the groove 102 can cooperate with the connecting rod 3.

[0041] In this embodiment, when the precast concrete slab 1 is embedded in the soil layer, the inclined surface 101 is covered with soil. Therefore, when the precast concrete slab 1 tilts, the inclined surface 101 will need to lift a large amount of soil, thereby increasing the difficulty of tilting the precast concrete slab 1 and ensuring the stability when the precast concrete slab 1 is embedded.

[0042] The groove 102 is mainly used to install the connecting rod 3, and the connecting rod 3 connects the adjacent two precast concrete slabs 1 through the groove 102.

[0043] As a further solution of the present utility model, a notch 301 is arranged at the top of the connecting rod 3. When the connecting rod 3 is buried in the soil layer, the soil layer will pass through the notch 301 to increase the difficulty of the connecting rod 3 moving upward.

[0044] In this embodiment, since a slotted groove 301 is provided at the top of the connecting rod 3, when the connecting rod 3 is buried in the soil layer, the connecting rod 3 will increase the contact area with the soil layer through the slotted groove 301, making it difficult for the connecting rod 3 to move upward, thus ensuring the stability of the connecting rod 3 during installation.

[0045] As a further solution of the present utility model, an extrusion surface 302 is provided at the bottom of the connecting rod 3, and the extrusion surface 302 is in mutual fit with the inclined surface 101.

[0046] When the connecting rod 3 moves towards the column 2, the connecting rod 3 will push the inclined surface 101 through the extrusion surface 302, causing the precast concrete slab 1 to have a tendency to move downward.

[0047] In this embodiment, since the extrusion surface 302 is in mutual fit with the inclined surface 101, when one of the two adjacent precast concrete slabs 1 is inclined, it will push the connecting rod 3 to move towards the other precast concrete slab 1 through the groove 102. During this process, the extrusion surface 302 at the bottom of the connecting rod 3 will push the inclined surface 101 on the other precast concrete slab 1, making the other precast concrete slab 1 have a tendency to move downward, thus ensuring the stability of the other precast concrete slab 1.

[0048] During the movement of the connecting rod 3, the inclined surface 101 on the other precast concrete slab 1 will generate a reaction force on the connecting rod 3, making the connecting rod 3 have a tendency to move upward. Also, due to the existence of the slotted groove 301, it is difficult for the connecting rod 3 to move upward.

[0049] As a further solution of the present utility model, one end of the connecting rod 3 is located inside the groove 102, and an inclined surface 303 is provided at one end of the connecting rod 3;

[0050] The size of the groove 102 along the length direction of the connecting rod 3 is larger than the size of one end of the connecting rod 3, so that there is a gap between the inclined surface 303 and the groove 102.

[0051] In this embodiment, since there is a gap between the inclined surface 303 and the groove 102, after embedding, soil will fill the gap.

[0052] Also, due to the existence of the inclined surface 303, when the connecting rod 3 slides in the groove 102, the connecting rod 3 can push the soil in the groove 102 upward through the inclined surface 303, thus providing space for the movement of the connecting rod 3.

[0053] As a further solution of the present utility model, a steel bar 5 is fixedly provided at the other end of the connecting rod 3, and the steel bar 5 is connected to the adjacent steel bar 5 through a component.

[0054] In this embodiment, the main function of the steel bar 5 fixedly arranged at the other end of the connecting rod 3 is to facilitate the connection with another connecting rod 3. Among them, the steel bars 5 on the two connecting rods 3 can be connected through components.

[0055] As a further solution of the present utility model, an opening 103 is provided at the bottom of the precast concrete slab 1, and the opening 103 can increase the stability of the precast concrete slab 1.

[0056] In this embodiment, since an opening 103 is provided at the bottom of the precast concrete slab 1, when the precast concrete slab 1 is embedded in the soil layer, the soil will also enter the opening 103, thereby improving the stability of the precast concrete slab 1 during embedding.
