Technical Field
[0001] The utility model relates to the technical field of wooden column foot connection structures, in particular to a column foot used for four-piece wooden columns. Background Art
[0002] A four-piece column is a column or pillar made of four pieces of wood joined vertically. This construction method is often used in traditional buildings, especially in wooden structures. Four-piece columns usually have high strength and stability, and can be used to support the weight of the building and resist external pressure and wind.
[0003] The existing four-piece wooden column needs to have its column foot planted with reinforcement to improve the overall strength. In order to reduce the complexity of the structure and improve the stability of the structure, a column foot for the four-piece wooden column is now proposed. Utility Model Content
[0004] The utility model aims to provide a column foot for four-piece wooden columns to solve the problems raised in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A column foot for a four-piece wooden column comprises an embedded part, a vibration hole is opened on the top of the embedded part, a connecting part is fixedly connected to the top of the embedded part, a shear key is fixedly connected to the bottom of the embedded part, and a two-layer concrete structure top and a concrete column are arranged at the bottom of the embedded part.
[0007] Preferably, the embedded part is provided with an anchor hole, in which a chemical anchor is inserted and extends to the top of the second-floor concrete structure and the concrete column.
[0008] Preferably, the number of the anchor holes is sixteen and they are evenly distributed on the embedded parts.
[0009] Preferably, there are four connecting members, which are distributed in a circle around the vibrating hole and located at the four corners of the embedded part.
[0010] Preferably, each of the connecting members is provided with four threaded holes, and the connecting members are fixedly connected to wooden columns by bolts.
[0011] Preferably, the diameter of the vibration hole is millimeters, the number of the shear keys is four, and they are symmetrically arranged on the vibration holes respectively, and a cross reinforcement rib is provided at the bottom of the connecting piece, and is welded to the top of the embedded part through the cross reinforcement rib.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] While satisfying the architectural effect, four wooden columns have two columns in each direction, forming a tensile and compressive force couple, thus achieving the bending resistance effect at the base of the column. Therefore, the column base does not need to be rebar-planted, and the shear resistance form of insert plates and through-bolts / pins can be directly adopted. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense, for example, they can be fixedly connected or set, or detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.
[0023] like Figure 1-4 As shown, a column base for a four-piece wooden column includes: an embedded part 1, a vibration hole 2 is opened on the top of the embedded part 1, a connecting part 4 is fixedly connected to the top of the embedded part 1, a shear key 3 is fixedly connected to the bottom of the embedded part 1, and a two-layer concrete structure top 5 and a concrete column 6 are arranged at the bottom of the embedded part 1.
[0024] The embedded part 1 is provided with an anchor hole 7 , in which a chemical anchor is inserted and extends to the top 5 of the second-floor concrete structure and the concrete column 6 .
[0025] There are sixteen anchor holes 7 , which are evenly distributed on the embedded part 1 .
[0026] There are four connecting members 4 , which are distributed in a circle around the vibrating hole 2 and located at the four corners of the embedded member 1 .
[0027] Four threaded holes are formed on each connecting member 4 , and a wooden column 8 is fixedly connected to the connecting member 4 by bolts 9 .
[0028] The diameter of the vibration hole 2 is 150 mm. There are four shear keys 3 which are symmetrically arranged on the vibration hole 2. A cross reinforcement rib is arranged at the bottom of the connecting piece 4 and is welded to the top of the embedded part 1 through the cross reinforcement rib.
[0029] The working principle of the utility model is as follows:
[0030] When in use, the embedded part 1 is embedded between the top 5 of the second-floor concrete structure and the concrete column 6, and the firmness is improved by embedding chemical anchor bolts. At the same time, the strength of the entire column foot is improved by four shear keys 3 distributed on the periphery of the vibration hole 2 with a diameter of 150 mm, and then the four wooden columns 8 are plugged into the four connecting parts 4 in turn, and each wooden column 8 is connected and fixed by four M12 8.8 grade high-strength bolts. The four wooden columns 8 meet the architectural effect. Since there are two columns in each direction, a tensile and compressive force couple is formed to achieve the bending resistance effect of the column bottom. Therefore, the column foot does not need to be planted with reinforcement, and the shear resistance form of the plug plate and the through bolts / pins can be directly adopted.
