Description

Technical Field

[0001] The invention relates to the technical field of building construction, and more specifically to a rapid assembly method of an upper chord-cut and welded ball grid frame. Background Art

[0002] In order to lay the floor decking directly on the grid roof, the upper chord flattened welded ball grid came into being. The upper chord ball is a cut crown ball, and a rectangular tube is used as the upper chord tube to create the condition of a flat upper chord of the grid for laying the floor decking.

[0003] The conventional gantry assembly method of "first assembling the balls and then assembling the tubes" will make it difficult for the rectangular tubes to be inserted between the welded balls when dealing with the upper chord flattened welded ball gantry due to the depth of the balls when the rectangular tubes intersect with the welded balls.

[0004] Furthermore, in the existing scheme, three methods are generally used for assembling the grid. The first is to locate the position and orientation of the crown ball through BIM and three-dimensional laser scanning technology and then assemble it; the second is to use an assembly frame to convert the assembly of the folded grid into a flat grid assembly; the third is to use the locator and positioning method of the ball node to realize the grid installation.

[0005] However, these existing solutions cannot perform special installation on the upper chord flattened welded ball grid frame, and it is difficult to ensure the assembly quality and speed of the upper chord flattened welded ball grid frame. Summary of the invention

[0006] In view of the above problems, the purpose of the present invention is to provide a method for quickly assembling an upper chord flattened welded ball grid frame to solve the problem that the existing solution cannot perform special installation on the upper chord flattened welded ball grid frame.

[0008] Prefabricate at least two sections of ball tube line components; wherein each of the ball tube line components includes at least two upper-string truncated balls;

[0009] A bottom support assembly is set up at a first preset position, wherein the bottom support assembly includes at least two groups of portal frames and at least three sections of lower chord auxiliary supports; each group of portal frames is arranged between two adjacent sections of lower chord auxiliary supports, and the lower chord auxiliary supports include at least three lower chord balls;

[0010] Place each section of the ball pipeline component on the corresponding portal frame in turn, and connect each upper chord crowning ball with the corresponding lower chord ball.

[0011] In addition, a preferred solution is that the ball-tube-line component further includes an upper-chord moment tube connected between two adjacent upper-chord truncated crown balls; and the prefabricated ball-tube-line component includes:

[0012] Arranging a tire mold frame at a second preset position, and providing at least two raising plates on the tire mold frame;

[0013] Placing the first upper-chord crown-cutting ball on the tire mold frame, and placing the first upper-chord rectangular tube on the padding plate;

[0014] Move the first upper string moment tube so that its end opening is aligned and connected with the side surface of the first upper string crown cutting ball;

[0015] The second upper-chord truncated crown ball is placed on the tire mold frame, and the second upper-chord truncated crown ball is moved so that its side surface is matched and connected with the end opening of the first upper-chord rectangular tube.

[0016] In addition, a preferred solution is that the prefabricated ball pipeline component also includes:

[0017] Repeat the installation steps of the first upper string moment tube and the second upper string truncated crown ball to complete the installation of the remaining upper string moment tubes and the remaining upper string truncated crown balls.

[0018] In addition, a preferred solution is that the lower chord auxiliary support further includes a lower chord ball holder corresponding to each lower chord ball; and the bottom support assembly set up at the first preset position includes:

[0019] Laying a roadbed at a first preset position, and arranging each lower chord ball support on the roadbed;

[0020] Place each lower string ball in the corresponding lower string ball holder.

[0021] In addition, a preferred solution is that the lower chord auxiliary support further includes a lower chord circular tube between two adjacent lower chord balls; and the bottom support assembly set up at the first preset position further includes:

[0022] Assemble each lower chord circular tube between two adjacent lower chord balls to complete the auxiliary support of each section of the lower chord.

[0023] In addition, a preferred solution is that the setting up of the bottom support assembly at the first preset position further includes:

[0024] The corresponding lower chord balls between two adjacent lower chord auxiliary supports are connected through the lower chord circular tube.

[0025] In addition, a preferred solution is that the step of connecting each upper string shorn ball with the corresponding lower string ball comprises:

[0026] An oblique belly circular tube is connected between each upper string cut crown ball and the corresponding lower string ball.

[0027] In addition, a preferred solution is that the rapid assembly method of the upper-chord flattened welded ball grid provided by the present invention also includes: connecting the corresponding upper-chord truncated balls between adjacent ball tube line components through an upper-chord rectangular tube with a code plate.

[0028] In addition, a preferred solution is that the corresponding upper-chord truncated balls between adjacent ball-tube line components are connected through an upper-chord rectangular tube with a code plate, including:

[0032] Compared with the prior art, the above-mentioned rapid assembly method of the upper chord flattened welded ball grid frame according to the present invention provides a special rapid assembly method of the upper chord flattened welded ball grid frame in view of the difficulty in implementing the interlocking of the rectangular tubes between the upper chord cut crown balls in the upper chord flattened welded ball grid frame. By studying the connection characteristics of the upper chord balls and the rectangular tubes, the upper chord structure of the grid frame is decomposed into two parts: the ball tube line component and the interlocking upper chord rectangular tube (including the connecting components between adjacent ball tube line components). The upper chord rectangular tube and the upper chord cut crown balls are moved (preferably slid) to complete the assembly of the ball tube line component on the ground. Then, the ball tube line component is supported by setting a door frame and the upper chord rectangular tube is hung between the ball tube line components by setting a code plate. The moving operation is used again to complete the connection between the ball tube line component and the upper chord interlocking rectangular tube, and the overall assembly of the grid frame is completed efficiently, which can solve the problem that the assembly quality and speed of the upper chord flattened welded ball grid frame are difficult to ensure. The construction method can reduce the difficulty of interlocking the upper chord rectangular tube, has high construction efficiency, is simple to operate, and has a safe and reliable construction process.

[0089] Install the oblique belly round tube 3.3, so that its two ends are connected with each upper chord cut crown ball 2.1 and the corresponding lower chord ball of the first section ball pipeline component (such as Fig.12 shown).

[0090] After the first section of the ball pipeline components are connected, the second section of the ball pipeline components 7.2 are installed. The process includes:

[0093] Step 13: Move the upper-chord rectangular tube 3.1 with the code plate 6 between the upper-chord truncated crown balls 2.1 toward the first-section ball tube line component; then move the second-section ball tube line component as a whole toward the first-section ball tube line component, so that both ends of the upper-chord rectangular tube 3.1 with the code plate 6 between the upper-chord truncated crown balls 2.1 coincide with and intersect the upper-chord truncated crown balls 2.1 of the first-section ball tube line component and the second-section ball tube line component (such as Fig.15 shown).

[0099] It can be seen from the above specific embodiments that the rapid assembly method of the upper chord flattened welded ball grid provided by the present invention provides a special rapid assembly method of the upper chord flattened welded ball grid frame in view of the difficulty in implementing the interlocking of the rectangular tubes between the upper chord cut crown balls in the upper chord flattened welded ball grid frame. By studying the connection characteristics of the upper chord balls and the rectangular tubes, the upper chord structure of the grid frame is decomposed into two parts: the ball tube line component and the interlocking upper chord rectangular tube (including the connecting components between adjacent ball tube line components). The upper chord rectangular tube and the upper chord cut crown balls are moved (preferably slid) to complete the assembly of the ball tube line component on the ground. Then, by setting a door frame to support the ball tube line component and setting a code plate to hang the upper chord rectangular tube between the ball tube line components, the moving operation is used again to complete the connection between the ball tube line component and the upper chord interlocking rectangular tube, and the overall assembly of the grid frame is completed efficiently, which can solve the problem that the assembly quality and speed of the upper chord flattened welded ball grid frame are difficult to ensure. The construction method can reduce the difficulty of interlocking the upper chord rectangular tube, has high construction efficiency, is simple to operate, and has a safe and reliable construction process.

However, those skilled in the art should understand that various improvements can be made to the rapid assembly method of the upper chord flattened welded ball grid frame proposed by the present invention without departing from the content of the present invention. Therefore, the protection scope of the present invention should be determined by the content of the attached claims.
