Description

Technical Field

[0001] The present invention relates to the technical field of structural engineering, and particularly to a roof support structure. Background Art

[0002] The memorial archway originated from the courtyard gates or neighborhood gates in ancient times, all of which were made of wood structures. The wooden memorial archway is also the original and most soulful form. In order to inherit its charm, the existing memorial archway buildings mainly use reinforced concrete columns and beams to replace wooden columns and beams, while the roof still adopts the traditional pure wooden structure form. The pure wooden structure of the roof mainly uses wooden brackets and wooden beams as stress and force transmission components. The wooden brackets are mainly composed of a series of wooden components stacked layer by layer vertically and horizontally, forming a bracket with a larger upper part and a smaller lower part. They are connected layer by layer through mortise and tenon joints to transmit the load of the upper wooden beam and support the weight of the eaves to increase the depth of the overhang.

[0003] In the process of implementing the existing technology, the inventor found that:

[0004] As the sizes of the eaves and the cantilever beam extending outwards increase, the length of the cantilever and the lifted height will also increase proportionally, which in turn increases the self-weight of the roof, and the load air volume of the entire roof surface is correspondingly large, easily leading to the possibility of the bracket tipping over, that is, causing the problem of poor overall stability of the memorial archway.

[0005] Therefore, it is necessary to provide a roof support structure with better stability to solve the problem that the pure wooden structure of the roof in the existing technology is prone to cause the bracket to tip over when reaching a certain roof load. Summary of the Invention

[0050] The following elaborates on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0051] Please refer to Figures 1 to 3 , in this application for a roof support structure 100, it includes: a roof bearing base 10; a plurality of bearing frames 11 arranged in rows on the end face of the roof bearing base 10; a wooden purlin assembly 12 surrounding the plurality of bearing frames 11; wherein, the bearing frame 11 specifically includes: a lattice column 110 arranged perpendicular to the roof bearing base 10; horizontal support members 112 symmetrically arranged on both sides of the lattice column 110 and perpendicularly connected to the lattice column 110; and diagonal support members 113 connected to the lattice column 110 and the horizontal support members 112 to form a triangular support.

[0052] Specifically, the roof bearing base 10 mainly provides support for the roof support structure 100. The roof bearing base 10 can be supported by erection with concrete columns, concrete beams, etc.

[0053] A plurality of bearing frames 11 arranged in rows on the end face of the roof bearing base 10. The bearing frames 11 are mainly used to support the roof. The bearing frame 11 is composed of a lattice column 110, horizontal support members 112, and diagonal support members 113. It can be understood that the bearing frame 11 provided in this application is mainly used to replace the traditional wooden dougong, that is, the force is changed from the previous wooden dougong to the bearing frame 11 for replacement. It should also be understood that the roof on the bearing frame 11 is still constructed with a wooden structure, that is, it is attached to the bearing frame 11 as a decorative structure and does not participate in the load transfer of the upper roof. This steel-wood combination application technology can make good use of the advantages and avoid the disadvantages, integrating the two structures into one. It can not only overcome the technical drawbacks of the traditional load-bearing wooden frame, such as high cost, poor stability, poor seismic resistance, and time-consuming construction, but also is conducive to maintaining the traditional architectural style.

[0054] In another embodiment, the lattice column 110 arranged perpendicular to the roof bearing base 10 at least includes a pair of paired column limb channel steels 1101, the concave surfaces of the paired column limb channel steels 1101 are arranged corresponding to each other, and the roof bearing base 10 is also provided with embedded parts for connecting with the paired column limb channel steels 1101.

[0055] Specifically, the lattice column 110 can be a pair of column split channel steels 1101 arranged in pairs, or two pairs of column split channel steels 1101 arranged in pairs, or more pairs of column split channel steels 1101 arranged in pairs. It should be pointed out that the lattice column 110 used in the present application is a pair of column split channel steels 1101, because it is lower in cost than the previous square steel, and its bending resistance is relatively good. In a preferred embodiment provided in the present application, the lattice column 110 preferably has two pairs of column split channel steels 1101 arranged in pairs. In addition, the concave surfaces of the column split channel steels 1101 arranged in pairs are arranged correspondingly, mainly considering the overall beauty of the bracket. The vertical roof bearing base 10 is also provided with embedded parts for connecting with the column split channel steels 1101 arranged in pairs, which can be understood as fixing the column split channel steels 1101 to the lower concrete beam through the embedded parts.

[0056] In another embodiment, the plurality of lattice columns 110 of the load-bearing frame 11 are connected by single angle steel scissors braces 1102. The single angle steel scissors braces 1102 are passed between the lattice columns 110 to enhance the tension between the lattice columns 110. In a preferred embodiment provided by the present application, two rows of single angle steel scissors braces 1102 are passed between the lattice columns 110 to enhance the tension between the lattice columns 110.

[0057] In another embodiment, a predetermined distance is also set between the plurality of bearing frames 11 arranged in a row on the end surface of the roof bearing base 10, and the predetermined distance is 0.5 meters to 1 meter. The specific distance between the bearing frames 11 also determines the stability of the bearing frames 11. If the distance between the bearing frames 11 is less than 0.5 meters, although the bearing frames 11 can play a bearing role, the increase in the number of bearing frames 11 is likely to increase the cost of the roof support structure 100. If the distance between the bearing frames 11 is greater than 1 meter, it is likely to cause the stability between the bearing frames 11 and the bearing frames 11 to decrease, and the stability of the roof support structure 100 is relatively reduced. After many practices of the applicant, it is believed that when the bearing frame is set at 0.5 meters to 1 meter, the stability of the bearing frame is relatively good, and accordingly, the stability of the roof support structure 100 is optimal. In an embodiment provided by the present application, the distance between the bearing frames 11 and the bearing frames 11 is preferably set to 0.8 meters to achieve the best stability of the roof support structure 100.

[0058] In another embodiment, the horizontal support members 112 symmetrically arranged on both sides of the lattice column 110 and vertically connected to the lattice column 110 specifically include: the horizontal support members 112 are respectively connected to the paired column limb channel steels 1101 of the lattice column 110; the horizontal support members 112 symmetrically arranged on both sides of the lattice column 110 and vertically connected to the lattice column 110 further include: column web plates 116 are arranged between the paired column limb channel steels 1101, and the horizontal support members 112 are connected to the column web plates 116.

[0059] Specifically, the horizontal support members 112 can be horizontally arranged steel beams, for example, channel steels. The horizontal support members 112 symmetrically arranged on both sides of the lattice column 110 can be that the horizontal support members 112 are respectively connected to the paired column limb channel steels 1101 of the lattice column 110. It can be understood that if the lattice column 110 is a pair of paired column limb channel steels 1101, the horizontal support members 112 can be respectively connected to the paired column limb channel steels 1101. Of course, it can also be that column web plates 116 are arranged between the paired column limb channel steels 1101, and the horizontal support members 112 are connected to the column web plates 116, that is, column web plates 116 are respectively arranged at the symmetrically opposite ends of the paired column limb channel steels 1101, the column web plates 116 are respectively connected with the horizontal support members 112, and the horizontal support members 112 are perpendicular to the lattice column 110. It should also be noted that the horizontal support members 112 are also correspondingly perpendicular to the side wall end faces of the roof bearing base 10.

[0060] It should also be noted that if the lattice column 110 is two pairs of paired column limb channel steels 1101, it can be understood that if the paired column limb channel steels 1101 are to be connected to the horizontal support members 112, column web plates 116 need to be arranged between the paired column limb channel steels 1101 to connect the horizontal support members 112. It should also be understood that the column web plates 116 are also used to connect between a pair of paired column limb channel steels 1101 or multiple pairs of paired column limb channel steels 1101. It should be noted that if the lattice column 110 adopts two pairs of paired column limb channel steels 1101, the symmetrically arranged horizontal support members 112 are connected to the column web plates 116 of the paired column limb channel steels 1101 to form two symmetrically arranged horizontal steel beams, that is, a total of 4 horizontal steel beams. It should also be noted that a steel beam connecting plate can be arranged between the two symmetrically arranged horizontal steel beams to increase the connection performance of the horizontal steel beams, thereby ensuring the stability of the roof support structure 100.

[0061] In another embodiment, the connection position between the horizontal support member 112 and the column limb channel steel 1101 is determined according to the beam-passing position.

[0062] Specifically, the connection position between the horizontal support member 112 and the column split channel steel 1101 is where the horizontal support member 112 is cantilevered at the corresponding position of the column. To ensure the integrity of the bracket set and the upper wooden components, the horizontal support member 112 is set to be flush with the arch body, and the position is parallel to the position of the cantilevered wooden through beam in the traditional antique archway.

[0063] In another embodiment, the diagonal support member 113 that forms a triangular support when connected to the lattice column 110 and the horizontal support member 112 specifically includes: one end of the diagonal support member 113 is connected to the end of the column split channel steel 1101 away from the roof bearing base 10; the other end of the diagonal support member 113 is connected to the horizontal support member 112; the included angle formed between the diagonal support member 113 and the horizontal support member is 30° to 45°. The diagonal support member 113 that forms a triangular support when connected to the lattice column 110 and the horizontal support member 112 further includes: one end of the diagonal support member 113 is connected to the column split channel steel 1101; the other end of the diagonal support member 113 is connected to the end of the horizontal support member 112 away from the column split channel steel 1101; the included angle formed between the diagonal support member 113 and the horizontal support member 112 is 45° to 60°.

[0064] Specifically, one end of the diagonal support member 113 is connected to the horizontal support member 112, and the other end is connected to the end of the column split channel steel 1101 away from the roof bearing base 10. The diagonal support member 113 is made of single-angle steel. In a preferred embodiment provided by the present application, the diagonal support member 113 can be connected to the end of the column split channel steel 1101 away from the roof bearing base 10 at one end, and the other end of the diagonal support member 113 is connected to the horizontal support member 112. That is, the diagonal support member 113 and the column split channel steel 1101 are connected end to end, and the other end of the diagonal support member 113 is connected to any position of the roof bearing base 10. It should be noted that the included angle formed between the diagonal support member 113 and the horizontal support member 112 is 30° to 45°. Of course, it can also be that one end of the diagonal support member 113 is connected to the column split channel steel 1101, and the other end of the diagonal support member 113 is connected to the end of the horizontal support member 112 away from the column split channel steel 1101. That is, the diagonal support member 113 and the column split channel steel 1101 are connected end to end at any position, and the other end of the diagonal support member 113 is connected to the roof bearing base 10 end to end. It should be noted that the included angle formed between the diagonal support member 113 and the horizontal support member 112 is 45° to 60°. It can be understood that the included angle between the diagonal support member 113 and the horizontal support member 112 mainly depends on the overall shape of the roof bearing base 10 in the roof support structure 100. For example, if the roof bearing base 10 is horizontal, the included angle is set to a certain fixed degree. If the roof bearing base 10 is arc-shaped, the included angle needs to be set according to specific circumstances.

[0065] It should also be noted that if the lattice column 110 is composed of two pairs of column split channel steels 1101 arranged in pairs, the corresponding horizontal support members 112 are 4 horizontal steel beams, and correspondingly, the diagonal support members 113 are 4 diagonal steel beams. Two triangular steel frameworks are formed between the horizontal support members 112, the diagonal support members 113, and the lattice column.

[0066] In another embodiment, the wooden truss member 12 surrounding the plurality of load-bearing frameworks 11 specifically includes: a first wooden truss 120 erected on the column split channel steels 1101 arranged in pairs of the plurality of load-bearing frameworks 11, at the other end of the column split channel steels 1101 arranged in pairs away from one end of the roof bearing base 10; a second wooden truss 121 surrounding the horizontal support members 112 of the plurality of load-bearing frameworks 11; a third wooden truss 122 surrounding the diagonal support members 113 of the plurality of load-bearing frameworks 11; wherein, column through-connection connectors 1201 are provided at both ends of the first wooden truss 120 and are connected to the column split channel steels 1101 arranged in pairs.

[0067] Specifically, the wooden purlin in the wooden purlin assembly 12 is bolted to the bearing frame 11. The wooden purlin assembly 12 provided in this application includes a first wooden purlin 120, a second wooden purlin 121, and a third wooden purlin 122. The purlin is mainly a wooden member used to support the roof rafters. Through the wooden purlin assembly 12 provided in this application, other wooden decorative structures are arranged on the wooden purlin assembly 12, so that the overall roof support structure 100 retains the architectural style of all-wood structures.

[0068] It should be noted that, as shown in the figure, the first wooden purlin 120 is erected on the lattice columns 110 of several bearing members, the second wooden purlin 121 surrounds the ends of the symmetric horizontal supports 112 on several bearing members, and the third wooden purlin 122 surrounds the middle position of the symmetric diagonal supports 113 on several bearing members.

[0069] It should be noted that the first wooden purlin 120, the second wooden purlin 121, and the third wooden purlin 122 can be fixed to the bearing frame 11 by bolts. The first wooden purlin 120 is erected on the lattice columns 110 of the several bearing frames 11, and column through connectors 1201 are also provided at both ends of the first wooden purlin 120 to fix the upper wooden purlin.

[0070] In another embodiment, the second wooden purlin 121 surrounding the horizontal supports 112 of the several bearing frames 11 specifically includes: a horizontal closing beam 1210 is also surrounded at the other end of the horizontal supports 112 of the several bearing frames 11 away from the end connected to the lattice column 110; the second wooden purlin 121 is connected to the horizontal closing beam 1210.

[0071] Specifically, the setting of the horizontal closing beam 1210 is mainly to seal the ends of the horizontal supports 112 on the premise of ensuring the roof support structure 100. Specifically, it can be realized through the horizontal closing beam 1210. The inside of the horizontal closing beam 1210 can be filled with solid wood strips to ensure the appearance effect of the outer facade. It can be understood that the horizontal closing beam 1210 and the horizontal support 112 can be connected by bolts or by welding.

[0072] In another embodiment, some of the several bearing frames 11 in the several bearing frames 11 further include: another horizontal support 114 provided on the paired column split channel steels 1101 and perpendicular to the symmetric horizontal supports 112 on the same horizontal plane; another diagonal support 115 that is connected to the lattice column 110 and another horizontal support 114 to form a triangular support.

[0073] Specifically, in addition to the horizontally arranged support members 112 symmetrically disposed on the lattice columns 110 of several load-bearing frames 11 of the roof support structure 100, another horizontally arranged support member 114 is provided on the lattice columns 110 of some of the load-bearing frames 11. This another horizontally arranged support member 114 mainly refers to the load-bearing frames 11 at both ends of several rows of load-bearing frames 11 arranged in rows. It can be understood that by providing another horizontally arranged support member 114 at both ends of the load-bearing frames 11, the second wooden purlin 121 can be surrounded more beautifully. Correspondingly, another diagonal support member 115 can also be provided between the another horizontally arranged support member 114 and the lattice column 110, which can make the third wooden purlin 122 surrounded more beautifully.

[0074] It should be noted that in the roof support structure 100 provided in the present application, the lattice columns 110, the horizontally arranged support members 112, and the diagonal support members 113 in the load-bearing frame 11 can all be connected by welding, so that the welding stiffness and connection performance of the load-bearing frame 11 are relatively good, and at the same time, the airtightness and watertightness of the roof support structure 100 are ensured. And compared with the traditional pure wooden structure, the steel-wood combination in the present application has high strength, good toughness, and relatively light weight of the steel itself. Compared with the previous micro type of the wooden bracket toppling forward under force, the roof support structure 100 provided in the present application can improve the overall stability of the memorial archway.

[0075] It should also be noted that as Figure 4 shown, the load-bearing frame 11 can be pre-assembled and fabricated in the factory and then transported to the site for construction and assembly, which is relatively simple compared with the traditional pure wooden structure. And due to the construction progress problem of the traditional pure wooden structure, the moisture content in the pure wooden structure is difficult to control, and there are many problems such as cracking and rotting of the wooden components. And if a large amount of high-quality wood is selected and measures such as degreasing and drying are taken, the project cost is relatively high. Relatively speaking, the roof support structure 100 provided in the present application has a relatively low cost.

[0076] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
