Description

Technical Field

[0001] This utility model belongs to the field of antique architecture, specifically relating to the wooden-clad steel support structure of a hanging flower gate. Background Technology

[0002] Currently, traditional hanging flower gate eaves are generally constructed entirely of wood (such as the "eaves" method recorded in the *Yingzao Fashi*). This typically includes hanging flower columns, eaves beams, hanging ornaments, connecting brackets, and side panels. The hanging flower columns are located below the eaves beams, and the connecting brackets are connected to the eaves beams via the side panels and are situated above the eaves beams. The eaves beams connect to the end beams, which in turn connect to the columns or beams. Due to its pure wood structure, it has significant drawbacks: the wood is prone to rot and insect infestation in humid environments, with an average lifespan of only 30-50 years. It requires frequent maintenance, with a full application of tung oil every 3-5 years, and each maintenance cycle accounts for 5%-8% of the total cost; post-disaster repair costs account for 70% of the total cost; furthermore, the wood has low bending strength, only 12-15 MPa, resulting in excessive deflection over large spans, poor seismic performance, and a tendency for joints to disintegrate under strong earthquakes.

[0003] Therefore, it is necessary to design a traditional Chinese hanging flower gate structure to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a wooden-clad steel support structure for hanging flower gates that combines the style of ancient buildings with high load-bearing capacity, and has the advantages of corrosion resistance and improved load-bearing capacity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wooden-clad steel support structure for an ancient building's hanging flower gate, comprising a hanging flower column, eaves beam, hanging ornament, connecting mechanism, and a clamping board. The hanging flower column is connected to the eaves beam below, and the connecting mechanism is connected to the eaves beam through the clamping board.

[0006] The eaves beam is a composite load-bearing component, consisting of a stainless steel square tube with closed ends inside and a wooden board covering the outside. The stainless steel square tube and the wooden board covering the outside are connected by concealed bolts. Angle brackets are fixedly connected to the bottom of the eaves beam, and the angle brackets fix the hanging ornaments.

[0007] Preferably, the wooden board has a 5mm deep anti-deformation groove on the inner side facing the stainless steel square tube.

[0008] Preferably, the stainless steel square tube has a rectangular cross-section, and the wooden board has a thickness of 20mm.

[0009] Preferably, the concealed bolts are countersunk bolts, which are arranged in two horizontal rows, and the longitudinal spacing between the countersunk bolts is ≤200mm.

[0010] Preferably, the countersunk bolt is embedded 2mm into the wooden board, and the resulting recess is filled with wood wax oil.

[0011] Preferably, the corner bracket is an L-shaped stainless steel piece, the vertical side of which is fixed to the eaves with bolts, and the horizontal side supports the hanging upper edge.

[0012] Preferably, a mortise is provided at the top of the pendant column, and a tenon steel piece is welded to the end of the eaves beam facing the pendant column. The tenon steel piece is inserted into the mortise and then fixed by a transverse bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The bending load capacity is improved by using steel-wood composite eaves, which increases to more than 160kN·m.

[0015] (2) The maintenance cycle is extended to ≥15 years.

[0016] (3) Post-disaster repair costs were reduced to 15% of the original cost. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model discloses a wooden-clad steel support structure for an ancient building's hanging flower gate, comprising a hanging flower column 1, an eaves 2, a hanging ornament 3, a connecting mechanism 4, and a mortise and tenon panel 5.

[0023] The pendant column 1 is fixedly connected to the bottom of the eaves beam 2, and the connecting mechanism 4 is connected to the top of the eaves beam 2 through the clamping board 5. The eaves beam 2 is fixedly connected to the end beam, which is connected to the column or beam.

[0024] The eaves beam 2 consists of a stainless steel square tube 21, closed at both ends, with an electrolytically polished outer surface. Merbau wood planks 22 are wrapped around the outer surface of the stainless steel square tube 21 and connected using concealed bolts. These concealed bolts are countersunk bolts 23, made of stainless steel. The countersunk bolts 23 pass through the walls of both the Merbau wood plank 22 and the stainless steel square tube 21, fixing the Merbau wood plank 22 to the stainless steel square tube 21. The countersunk bolts 23 are embedded 2mm into the surface of the Merbau wood plank 22, and the resulting recess is filled with wood wax oil. The stainless steel square tube 21 has dimensions of 120×250×8mm, the Merbau wood plank 22 is 20mm thick, and the countersunk bolts 23 are M10 countersunk bolts, fixed in double rows both horizontally and vertically. The longitudinal spacing of the countersunk bolts 23 is ≤200mm, preferably 180mm. The moisture content of the Merbau wood plank 22 is controlled below 12%, preferably 10%. A 5mm deep anti-deformation groove is provided on the inner side of the stainless steel square tube 21. The Merbau wood panel 22 can be replaced with other wood panels, depending on the design requirements.

[0025] The bottom of the stainless steel square tube 21 of the eaves 2 is provided with an L-shaped stainless steel corner bracket 6. The vertical side of the stainless steel corner bracket 6 is fixed to the bottom of the stainless steel square tube 21 by stainless steel bolts, and the horizontal side supports the upper edge of the hanging 3, thus providing support for the hanging 3.

[0026] A 120×250×100mm mortise 11 is opened at the top of the pendant column 1; a tenon steel piece 24, 250mm long, is welded to the end of the stainless steel square tube 21 of the eaves beam 2 facing the pendant column 1. After the tenon steel piece 24 is inserted into the mortise 11, several Φ12 horizontal holes are drilled on the pendant column 1 at the tenon steel piece 24 and the mortise 11, and horizontal bolts 12 are inserted into the horizontal holes to connect and fix the tenon steel piece 24 and the pendant column 1. When the tenon steel piece 24 is welded, the part of the stainless steel square tube 21 where the tenon steel piece 24 is welded is not covered with a Merbau wood board 22.

[0027] The eaves structure, with its wooden-clad steel purlins, utilizes stainless steel square tubing 21 for core load-bearing capacity, while the outer sheath of Merbau wood planks 22 maintains its traditional appearance. Corner brackets 6 enable the non-destructive installation of hanging ornaments 3. Mortise joints 11 and tenon steel fittings 24 form a seismic-resistant joint. Static load tests show that the eaves' bending capacity has increased to over 160 kN·m, and its ultimate bearing capacity reaches 195 kN·m, meeting the seismic fortification requirements of intensity 8.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
