Description

Technical Field

[0001] This utility model belongs to the field of wood structure building installation technology, and more specifically, this utility model relates to a concealed decorative column base node. Background Technology

[0002] Decorative columns consist of a capital, shaft, and base. Besides bearing weight, they also serve an aesthetic purpose, forming a cohesive whole with walls, roofs, and other interior and exterior designs. In current decorative column installations, the column base joint is a crucial point requiring special attention. Glulam (laminated laminated timber) decorative column components typically have high requirements for exterior finishes when installed indoors.

[0003] ① Currently, column base joints are commonly used, which are pre-embedded in the concrete foundation by pre-embedded anchor bars and pre-embedded plates. However, this method cannot meet the requirements for pre-embedding when the foundation for interior decoration has already been completed.

[0004] ② The column base usually uses a cross-shaped insert plate, which is made by cutting a groove in the glued laminated timber column base and using pins to connect and fasten it. The surface has pin holes and machining grooves, which involves a lot of milling of glued laminated timber.

[0005] ③ In interior decoration, due to the foundation treatment method, there are differences in ground level. Using integral hardware requires high assembly precision, making it difficult to control the level of the column base.

[0006] Patent CN201920092505.3, entitled "A Wooden Column Foot Node for Architectural Design," discloses a wooden column foot node for architectural design, comprising a glued laminated timber column, pull-out bolt I, pre-embedded pull-out bolt II, a stone base, a column spacing adjustment steel plate, a column foot adjustment horizontal steel plate, and a concrete pre-embedded steel plate. The glued laminated timber column is bolted to the stone base via pull-out bolt I. A column spacing adjustment steel plate is provided at the connection between the glued laminated timber column and the stone base. A column foot adjustment horizontal steel plate is provided at the end of the stone base away from the glued laminated timber column via pre-embedded pull-out bolt II. A concrete pre-embedded steel plate is provided below the column foot adjustment horizontal steel plate. The pre-embedded pull-out bolt II passes through the concrete pre-embedded steel plate and is bolted to the column foot adjustment horizontal steel plate. The wooden column foot uses a combination of three steel plates. The pre-embedded steel plate is used to fix the position of the pre-embedded bolts. The middle column foot adjustment horizontal steel plate can be adjusted to level the column base via bolts. The column spacing adjustment steel plate is used to adjust the column spacing by welding. This node can achieve a column positioning and elevation error within 1 cm.

[0007] The existing technology still requires construction to be carried out under the premise of pre-embedding. It cannot be applied to situations where the interior decoration foundation has been completed, and it does not meet the current complex construction conditions and requirements. Utility Model Content

[0008] To solve the aforementioned technical problems, this utility model provides a concealed decorative column base node.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A concealed decorative column base node includes a decorative column, hardware, and a base plate. The bottom of the decorative column is filled with anchoring adhesive and threaded anchoring rods are inserted, with the anchoring rods fixedly connected to the decorative column. The hardware is connected to the decorative column via the anchoring rods and tightened with nuts. The base plate is fixedly connected to the ground base, and the hardware is placed on the surface of the base plate and fixedly connected between the base plates.

[0011] This utility model discloses a concealed decorative column base node, wherein the base plate is provided with multiple bolt holes and the base plate is detachably connected to the ground base using chemical bolts.

[0012] This utility model discloses a concealed decorative column base node, wherein the bolt hole is an oval hole.

[0013] This utility model discloses a concealed decorative column base node, wherein the hardware is a "C" shaped hardware, and the "C" shaped hardware is welded to the base plate.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This application adopts a separate design for hardware components, foundation plate, etc., which solves the limitation that the completed foundation surface cannot meet the pre-embedded conditions.

[0016] 2. Using rebar instead of traditional methods avoids the need to cut grooves on the surface of the decorative column during the traditional installation of metal steel plates, which would damage the integrity and aesthetics of the decorative column.

[0017] 3. The anchor rods and hardware are connected by bolts and nuts. Tightening the nuts can change the height of the decorative column base, adding a leveling function and adjusting the consistency of the column base in terms of elevation.

[0018] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0025] The following description, with reference to the accompanying drawings, further details the specific implementation methods of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the function and working principle of each part, the manufacturing process, and the operation and use methods, so as to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the utility model concept and technical solution.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The concealed decorative column base node shown includes a decorative column 1, hardware 3 and base plate 4. The bottom of the decorative column 1 is filled with anchoring adhesive and threaded anchoring rods 7 are inserted. The anchoring rods 7 are fixedly connected to the decorative column 1. The hardware 3 is connected to the decorative column 1 through the anchoring rods 7 and tightened with nuts 8. The base plate 4 is fixedly connected to the ground base 2. The hardware 3 is placed on the surface of the base plate 4 and fixedly connected between the base plates 4.

[0027] The base plate 4 has multiple bolt holes and is detachably connected to the ground base layer 2 using chemical bolts 6.

[0028] With the above setup, the chemical bolt 6 relies on the combined action of the bond force between it and the concrete and the mechanical interlocking force to resist pull-out, and the bolt itself to resist shear. It is mainly used at the connection between new and old structures. Here, the convenience of fastening with chemical bolts is utilized to meet the high requirements for column base connections when glued laminated timber is used for interior decoration, while also facilitating disassembly and assembly.
