Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall hyperbolic structures, and particularly to a connecting structure and an assembly tool for novel special-shaped reticulated shell members. Background Art

[0002] With the rapid development of cities, hyperbolic special-shaped buildings are emerging continuously. For example, a large number of hyperbolic elements are applied in various venues and some commercial office projects. Generally, the hyperbolic facade is realized through a curtain wall. In the prior art, the formation of the hyperbolic surface of the curtain wall is mainly achieved through steel keels. In order to control costs and reduce the number of steel arc bends, generally, the method of fitting with triangular flat plates is adopted to achieve the hyperbolic effect. At the same time, in order to reduce the amount of welding at high altitudes and shorten the construction period, the entire large special-shaped reticulated shell is divided into several small reticulated shells, and then the small reticulated shells are fabricated on the ground in advance and then hoisted in pieces to the predetermined positions for splicing.

[0003] In the prior art, since the conventional method for splicing a special-shaped reticulated shell on the ground is to use a total station for measurement and positioning, and a jig is fabricated on site. On this basis, the members required for the reticulated shell are spliced and assembled one by one. At the same time, in order to connect adjacent members into a shape, usually, the methods of direct welding or pre-casting joint connecting pipes are used for connection. However, casting joint connecting pipes will greatly increase the construction cost and cause waste of resources. If direct welding is used, in actual operation, it is difficult to position the members, resulting in low efficiency and low accuracy. Therefore, it is necessary to design a novel connecting structure for special-shaped reticulated shell members to solve the above practical engineering problems. Summary of the Invention

[0004] The first object of the present invention is to provide a connecting structure that pre-provides positioning connection nodes to facilitate the connection between adjacent members and ensure accurate positioning. For this purpose, the present invention adopts the following technical solutions:

[0005] A novel connecting structure for special-shaped reticulated shell members, the special-shaped reticulated shell includes a frame and an inner frame, and the inner frame is connected within the triangular space surrounded by the frame; the frame includes a plurality of outer rods connected in a segmented manner, the inner frame includes a plurality of web members connected in a segmented manner, and the end of the web member is provided with a first node portion connected to an adjacent web member or a second node portion connected to an outer rod; a first connecting portion is provided on the second node portion of the web member, a positioning area for connecting with the web member is preset on the outer surface of the outer rod, forming a pre-positioning type assembly prompt state for the outer rod and the web member, and a second connecting portion is provided on the positioning area, and the first connecting portion and the second connecting portion are in a mutually matching convex or concave shape. Through the fitting connection of the first connecting portion and the second connecting portion, the second node portion of the web member is installed in the positioning area of the outer rod.

[0006] Further: the first connecting part is a plate-like structure protruding from the end of the web member, and the second connecting part is a groove-like structure penetrating through one side of the outer member.

[0007] Further: the first connecting part is arranged on the end wall of the web member, and its protruding direction is parallel to the wall of the web member.

[0008] Further: a third node part for connecting with an adjacent outer member is arranged at the end of the outer member.

[0009] Further: a convex plate is arranged on the opposite side end wall of the first node part of the web member to adapt to connect adjacent web members through the convex plate.

[0010] The second object of the present invention is to provide an assembly tool that is convenient for positioning and assembling. For this purpose, the present invention adopts the following technical solutions:

[0011] An assembly tool is used to assemble the special-shaped reticulated shell on an assembly platform laid on the ground. There are cushion blocks arranged on the assembly platform, and the cushion blocks are used to support the bottom of the connection nodes of the members on the special-shaped reticulated shell; the assembly tool further includes a laser level, and the height of the cushion block at the connection node of the special-shaped reticulated shell is adjusted and determined through the laser level.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

Detailed implementation manners

[0023] The present invention will be further described below in conjunction with the drawings and embodiments, but it shall not be used as the basis for limiting the present invention.

[0024] As Figures 1 - 7 shown, a connecting structure for a novel special-shaped reticulated shell member, the special-shaped reticulated shell includes a border 1 and an inner frame 2, and the inner frame 2 is connected within the triangular space surrounded by the border 1; the border 1 includes a plurality of outer rods 11 connected in a segmented manner, and the inner frame 2 includes a plurality of web members 21 connected in a segmented manner. The end of the web member 21 is provided with a first node part 211 connected to an adjacent web member 21 or a second node part 222 connected to the outer rod 11; a first connection part 223 is provided on the second node part 222 of the web member 21, and a positioning area connected to the web member 21 is preset on the outer surface of the outer rod 11, forming a pre-positioning assembly prompt state for the outer rod 11 and the web member 21. A second connection part 112 is provided on the positioning area, and the first connection part 223 and the second connection part 112 are in a mutually matching convex or concave shape. Through the fitting connection of the first connection part 223 and the second connection part 112, the second node part 222 of the web member 21 is installed in the positioning area of the outer rod 11.

[0025] As Figures 5 - 7 shown, in this embodiment, the first connection part 223 is a plate-like structure protruding from the end of the web member 21, and the second connection part 112 is a groove-like structure penetrating through one side rod body of the outer rod 11, so that when the outer rod 11 and the web member 21 are connected, the first connection part 223 of the web member 21 is directly inserted into the second connection part 112 of the outer rod 11, thereby forming a connection positioning. Through this connection method, the connection convenience of each small special-shaped reticulated shell of the overall large reticulated shell can be greatly improved, thereby improving the construction efficiency. At the same time, the fitting position of the second node part 222 of the web member 21 and the positioning area of the outer rod 11 is the welded connection part.

[0026] Among them, the first connection part 223 is provided on the end wall of the web member 21, and its protruding direction is parallel to the rod wall of the web member 21.

[0027] AsFigures 2 - 4 As shown, a third node portion 111 for connecting to an adjacent outer rod 11 is provided at the end of the outer rod 11.

[0028] In this embodiment, the positioning area of the outer rod 11 is preferably provided on the rod wall of the outer rod 11 near its third node portion 111, and in this way, the second node portion 222 of the web member 21 is connected to the rod wall of the outer rod 11 near its end side.

[0029] Wherein, a convex plate is provided on the opposite side end wall of the first node portion 211 of the web member 21 to adapt to the connection of adjacent web members 21. The number of convex plates on each web member 21 is two, and the convex plates are preferably flush with the rod wall of the web member 21. The convex plates on two or more web members 21 are connected to each other, and the joint surface between the convex plates is the welded joint, so that all the surrounding web members 21 can be connected.

[0030] In this embodiment, all the members of the special-shaped reticulated shell are steel structural members.

[0031] In this embodiment, weld seams are formed at the connection nodes of all the members through welding to connect and fix them accordingly.

[0032] As Figure 8 shown, this embodiment also provides an assembly tool. By using this assembly tool, the connection situation during the splicing of the outer rod 11 and the web member 21 can be simplified, and thereby the connection efficiency of the members can be improved.

[0033] This assembly tool assembles the special-shaped reticulated shell on an assembly platform 3 laid on the ground. A cushion block 4 is provided on the assembly platform 3. The cushion block 4 is used to support the bottom of the connection node of the members on the special-shaped reticulated shell. According to the characteristic that the connection nodes of the special-shaped reticulated shell are not at the same height, the positioning elevation of the connection node of the member can be determined by adjusting the height of the cushion block 4 accordingly, so as to determine the basic position required for the formation of the special-shaped reticulated shell; the assembly tool also includes a laser level 5, and the height of the cushion block 4 at the connection node of the special-shaped reticulated shell is adjusted and determined through the laser level 5.

[0034] In this embodiment, for the cushion blocks 4 corresponding to the connection nodes of the members at different positions of the special-shaped reticulated shell, the installation position of the member can be accurately and quickly determined by using the laser level 5 and in cooperation with a steel tape measure, so that the intersection positions of all the members reach the relative positioning elevation accuracy, and the positioning accuracy can be controlled within 2 mm by using the laser level 5 and the steel tape measure, improving the on-site measurement efficiency.

[0035] Please refer to Figures 1 - 8 , when assembling the special-shaped reticulated shell, the specific content is as follows:

[0036] All the members of the special-shaped reticulated shell are cut according to the three-dimensional model and processed by laser cutting, so as to ensure high cutting angle accuracy of the members and determine the required lengths and connection node positions of each outer member 11 and web member 21.

[0037] After each member is processed according to the model, all the members are sorted and numbered according to the model, and their positions are determined on site according to the member numbers. The installation positions on the cushion block 4 are determined by using the laser level 5 and the steel tape measure, so as to connect and cooperate through the first connecting portion 223 of the web member 21 and the second connecting portion 112 of the outer member 11, and assemble the frame 1 and the inner frame 2.

[0038] After the members are assembled to form the special-shaped reticulated shell, each connection node is welded, polished and surface-treated to complete the assembly. Finally, the pieces are hoisted separately by a lifting device.

[0039] The above embodiments are only a relatively optimal technical solution of the present invention. Those skilled in the art should understand that without departing from the principle and essence of the present invention, the technical solutions or parameters in the embodiments can be modified or replaced, and all should be covered within the protection scope of the present invention.
