Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated buildings, and particularly relates to a connecting device for pile foundation nodes of a prefabricated building structure. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to a factory. Building components and fittings are processed and manufactured in the factory, then transported to the building construction site, and finally assembled and installed on-site through reliable connection methods. Prefabricated buildings mainly include precast prefabricated concrete structures, steel structures, modern timber structures, etc. A conventional steel frame building structure generally requires a main skeleton structure, including internal connectors, vertically placed columns, horizontally placed beams, roof trusses, etc., and secondary plate members, such as being connected to the main frame structure in various ways to form vertically placed walls, horizontally placed floors, ceilings, roof members, etc.

[0003] Refer to Figure 1 , when installing a structural pile in the prior art, generally two methods are adopted. One is to directly use a fixing member 1004 for installation and fixation, and the other is to adopt a method of adding an installation groove and using the fixing member 1004 to fix the structural pile; in actual use of the two methods, since the fixing member is fixed by bolts 1001, the structural pile 1002 is subjected to relatively large stress at the connection with the pile foundation 1003, and it is easy to form a bending moment. At this time, in addition to the structural pile 1002 itself being stressed, the fixing member 1004 can also reinforce the structural pile. When the structural pile is inclined, the bolts are easily subjected to a large shear force and fail, affecting the fixing effect of the structural pile. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a connecting device for pile foundation nodes of a prefabricated building structure, which can effectively solve the technical problem that when the structural pile is inclined in the prior art, the bolts are easily damaged and fail due to stress.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is:

[0006] A connecting device for pile foundation nodes of a prefabricated building structure includes a first fixing component and a second fixing component, and the first fixing component and the second fixing component are used for being installed on a pile foundation and contacting with a structural pile installed on the pile foundation;

[0007] Wherein, the first fixing component and the second fixing component have the same structure. The first fixing component and the second fixing component both include a support plate, a limiting plate, and a locking screw. After the limiting plate is vertically connected to the support plate, an integral structure is formed;

[0008] The limit screw is used to fixedly arrange the limit plate on the pile base, and the support plate is used to contact the structural pile and extend into the installation groove arranged on the pile base.

[0009] Wherein, a strip-shaped groove is arranged on the limit plate, and the limit screw passes through the strip-shaped groove and is fixedly connected to the pile base.

[0010] Furthermore, a reinforcing rib is arranged between the support plate and the limit plate.

[0011] Wherein, after the limit plate and the support plate are connected, a T-shaped structure is formed, and the lower parts of the limit plate and the support plate are both attached to the pile base.

[0012] Preferably, the support plate and the structural pile are fixedly connected by screws.

[0013] Furthermore, a limit post is arranged at the bottom of the installation groove, and a limit hole matching the limit post is arranged at the bottom of the structural pile.

[0014] Wherein, the limit post has a frustum-shaped structure, the large end of the limit post contacts the bottom of the installation groove, and the limit post is fixedly arranged at the bottom of the installation groove by bolts.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] In the actual use of the present utility model, the structural pile is installed in the installation groove arranged on the pile base, and then the first fixing component and the second fixing component are used to fix the structural pile. Since the limit plate is vertically connected to the support plate to form an integral structure, when fixing, the support plate extends into the installation groove, which can play a supporting role. The support plate contacts the inner wall of the installation groove, greatly sharing the shear force borne by the limit screw, effectively preventing the limit screw from failing. At the same time, the support plate contacts the structural pile, which can also reinforce the structural pile, avoid a large bending moment at the connection of the structural pile, and achieve the purpose of protecting the structural pile.

[0035] Among them, a reinforcing rib 108 is provided between the support plate 105 and the limiting plate 106 to improve the overall stability of the device and avoid deformation during use.

[0036] Among them, after the limiting plate 106 is connected to the support plate 105, a T-shaped structure is formed, and the lower parts of both the limiting plate 106 and the support plate 105 are attached to the pile body base 103.

[0037] Furthermore, in actual use, the support plate 105 and the structural pile body 104 are fixedly connected by screws.

[0038] In some preferred embodiments, a limiting post 109 is provided at the bottom of the installation groove 111, and a limiting hole 110 matching the limiting post 109 is provided at the bottom of the structural pile body 104. The provided limiting post 109 can serve the purpose of positioning, making the installation of the structural column body more convenient, and also realizing the lateral limitation of the structural pile body 104.

[0039] Among them, further, the limiting post 109 has a frustum-shaped structure, the large end of the limiting post 109 contacts the bottom of the installation groove 111, and the limiting post 109 is fixedly arranged at the bottom of the installation groove 111 by bolts.
