Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a grid structure installation process. Background Art

[0002] The roof grid structure has the characteristics of large span, good integrity and stable structure. Nowadays, it is widely used in libraries, movie theaters, large shopping malls, etc.

[0003] There is a library like Figure 1 and Figure 2 As shown, a large-span skylight 12 is left in the middle of the roof 1 in the main frame of the building, and a grid structure needs to be installed in the large-span skylight 12. At the same time, a prism 11 is protruded on the roof 1, and the prism 11 is surrounded to form a rectangular frame structure. The skylight 12 is located inside the rectangular frame structure surrounded by the prism 11; the grid structure includes a grid upper chord 13, a grid lower chord 14, an upper chord ball 15, a lower chord ball 16 and a grid web 17. A plurality of grid upper chords 13 are fixedly connected to a plurality of upper chord balls. 15. Multiple lower chord balls 16 are fixedly connected between the multiple grid lower chord rods 14. The top ends of the truss web rods 17 are fixed to the upper chord balls 15, and the bottom ends are fixed to the lower chord balls 16. Among them, in the two rows of upper chord balls 15 located on both sides, a support seat 18 is welded to the bottom of each upper chord ball 15. When installing the truss structure, it is necessary to overlap the support seat 18 on the prism 11 and extend the truss structure into the skylight 12 so that the force of the entire truss structure is concentrated on the upper chord balls 15.

[0004] In the related art, when constructing the grid structure, an overall lifting construction process is adopted, which requires the grid structure to be assembled on the ground, and then the grid structure is lifted to above the roof 1 by a crane and transported to above the patio 12 and then lowered, so that the support seat 18 can be overlapped on the roof 1.

[0005] Regarding the related technologies mentioned above, when the main frame of the building is surrounded by lakes or there are dozens of meters of steps built around the main frame, the crane's lever arm not only needs to cross the roof 1 outside the patio 12, but also needs to cross the external environment of the main frame, so the required crane's lever arm will be too long. Therefore, when the truss structure is connected to the end of the lever arm, it is easy to cause the crane to overturn. Therefore, providing a process that can improve the safety of the entire construction process is an urgent problem to be solved. Summary of the Invention

[0006] In order to improve the safety of the entire construction process, the present application provides a grid structure installation process.

[0007] The present application provides a grid structure installation process that adopts the following technical solutions:

[0008] A grid structure installation process includes the following steps:

[0009] S1: Place the various components of the grid structure on the roof;

[0010] S2: Build two parallel rails on the roof, with the patio located between the two rails;

[0011] S3: A construction auxiliary device capable of traveling on the guide rail along the long side of the guide rail is provided on the guide rail;

[0012] S4: Fix the support base on the auxiliary construction equipment, and start to build the grid structure with the support base as the initial lap point until the grid structure is completed;

[0013] S5: The auxiliary construction equipment moves along the guide rails, and the grid structure moves along with the auxiliary construction equipment until the grid structure moves to the top of the skylight;

[0014] S6: Lower the grid structure until the support base is connected to the roof.

[0015] By adopting the above technical solution, during construction, the various components of the truss structure are hoisted onto the roof. Compared with hoisting the entire truss structure, the weight will be reduced, thereby reducing the possibility of the crane tipping over, thereby improving the safety performance of the operation; furthermore, after the truss structure is spliced, it is transported to the top of the skylight using construction auxiliary equipment in conjunction with guide rails. Compared with directly using a crane for transportation, the crane's lever arm can be shortened, thereby further reducing the possibility of the crane tipping over, further improving the safety of the operation.

[0016] Optionally, the S6 includes the following steps:

[0017] S61: Shorten the overall height of construction auxiliary equipment;

[0018] S63: Remove part of the guide rail between two auxiliary construction equipment to form a jacking operation area;

[0019] S64: Place a jack in the lifting area so that the jack can contact the upper ball after being extended;

[0020] S65: Transfer the force of the grid structure to the jack;

[0021] S66: Remove auxiliary equipment and guide rails used for construction;

[0022] S67: The jack drives the grid structure downward until the support base is connected to the prism;

[0023] S68: After further retracting the jack, remove the jack.

[0024] By adopting the above-mentioned technical solution, after the grid structure is transported to the top of the skylight, the height of the auxiliary construction equipment is shortened, which can drive the grid structure as a whole to move downward; after the force of the grid structure is transferred to the jack, the auxiliary construction equipment is removed, and then the jack drives the grid structure downward until the support seat is overlapped on the prism; during the entire construction process, the reason why the jack and the auxiliary construction equipment cooperate with each other is as follows: there is a height difference between the support seat and the grid structure. If the auxiliary construction equipment is not used but the jack is used directly, then after the jack is retracted, there is a situation where the support seat still cannot be overlapped on the prism. Therefore, the jack and the auxiliary construction equipment provided in this application cooperate with each other to solve the above-mentioned problem.

[0025] Optionally, the construction auxiliary equipment includes a walking mechanism and a supporting mechanism;

[0026] The support mechanism includes a plurality of support columns, one end of each support column is provided with a plug-in block, and the other end is provided with a plug-in hole for inserting the plug-in block on another support column;

[0027] The supporting mechanism is arranged on the traveling mechanism and can travel along the guide rail along with the traveling mechanism.

[0028] By adopting the above technical solution, multiple support columns are spliced ​​into vertical columns according to the required support height of the grid structure, so as to support the support seat and the grid structure; the support mechanism is then driven to move by the walking mechanism; by setting the support mechanism to be spliced, it can adapt to grid structures of different heights, and if the overall height of the support mechanism needs to be shortened, it is only necessary to remove some of the support columns.

[0029] Optionally, the construction auxiliary equipment further includes a lifting assembly, at least one of which is provided on each side of the support mechanism, and the lifting assembly includes a first drive cylinder, a second drive cylinder, and a clamping plate;

[0030] The first driving cylinder is connected to the traveling mechanism and can travel along the guide rail along with the traveling mechanism;

[0032] The clamping plates are fixedly connected to the second driving cylinder, and the clamping plates on both sides of the support mechanism can move toward or away from one side of the support mechanism under the action of the second driving cylinder to clamp or separate the support mechanism.

[0033] By adopting the above technical solution, when the first driving cylinder drives the splint to move to the second support column from bottom to top, the second driving cylinder drives the splint to move toward one side of the support column until the two splints clamp the support column. Subsequently, the first driving cylinder can drive the clamped support column to move upward until the plug-in block is separated from the plug-in hole. After the bottom support column is removed, the first driving cylinder drives the clamped support column to move downward, thereby changing the overall height of the support mechanism; the first driving cylinder adopted realizes the automation of the driving operation.

[0034] Optionally, it further includes a force unloading component, which includes a base, a material pushing seat, a lifting seat and a first elastic member;

[0035] The base is fixedly connected to the traveling mechanism and can move along the guide rail along with the traveling mechanism;

[0038] The two lifting seats are located between the two pushing seats, and the second wedge-shaped surface overlaps the first wedge-shaped surface;

[0039] The lifting seat is elastically connected to the upper part of the base through the first elastic member;

[0040] The supporting mechanism is overlapped on the lifting seat.

[0041] By adopting the above technical solution, before shortening the height of the support mechanism, the support column at the bottom is first moved down to the plug-in block and pulled out from the plug-in hole through the unloading component; when the unloading component is operating, the two pushing seats move away from each other, the lifting seat moves downward, and the support column at the bottom moves downward; by setting up the unloading component, there is no need to push the support mechanism and the grid structure to move upward as a whole.

[0042] Optionally, the force unloading assembly further includes a guide column, wherein the guide column is fixedly connected to the base, and the lifting seat is slidably connected to the guide column along a vertical direction.

[0043] By adopting the above technical solution, when the lifting seat is lifted and lowered along the guide post, the guide post plays a guiding role for the lifting seat, thereby preventing the lifting seat from deflecting during the lifting process.

[0044] Optionally, the construction auxiliary equipment also includes a material picking assembly, which includes a material picking block and a second oil cylinder, the second oil cylinder is fixedly connected to the base, the material picking block is connected to the second oil cylinder, and the material picking block can move toward or away from the side of the support column under the drive of the second oil cylinder.

[0045] By adopting the above technical solution, the second oil cylinder drives the picking block to move, and the picking block will push the bottom support column to separate from the clamped support block, which does not require manual operation and realizes automated operation.

[0046] Optionally, the construction auxiliary equipment further comprises a locking assembly, wherein the locking assembly comprises a lifting rod and an electromagnet;

[0047] The lifting rod can move up and down in the vertical direction on the walking mechanism. The electromagnet is fixedly connected to the lifting rod and can move downward with the lifting rod until it contacts the guide rail. The electromagnet can be adsorbed on the guide rail after being energized.

[0048] By adopting the above technical solution, the lifting rod and the electromagnet are moved downward until the electromagnet contacts the guide rail, and then the electromagnet is energized to make the guide rail and the electromagnet attract each other, so that the walking mechanism can be fixed on the guide rail, which can reduce the deviation of the guide rail.

[0049] Optionally, the locking assembly further includes a compression spring, which is connected between the lifting rod and the walking mechanism, and is used to drive the lifting rod to reset upward.

[0050] By adopting the above technical solution, after the electromagnet is powered off, the compression spring drives the lifting rod to reset upward, separating the electromagnet from the guide rail, realizing automated operation without the need for manual operation.

[0051] Optionally, the lifting assembly further includes a transfer seat, the transfer seat being connected between the first driving cylinder and the second driving cylinder, and the transfer seat being capable of moving in a vertical direction under the drive of the first driving cylinder, and the second driving cylinder being fixedly connected to the transfer seat;

[0052] The locking assembly further comprises an extrusion block, on which a third wedge surface and a fifth wedge surface are provided;

[0053] The adapter seat is provided with a fourth wedge surface, the third wedge surface is capable of contacting the fourth wedge surface, and when the fourth wedge surface rises with the adapter seat, it is capable of pushing the extrusion block to move toward the side of the lifting rod;

Therefore, when the adapter 62 rises, the abutment between the fourth wedge surface 621 and the third wedge surface 831 can push the extrusion block 83 toward the side away from the support mechanism 5.

[0095] Reference Figure 9 and Figure 10 The extrusion block 83 is further provided with a fifth wedge surface 832 , which is located on the side of the third wedge surface 831 away from the fourth wedge surface 621 , and is tilted downward toward the side close to the support mechanism 5 .

[0096] Reference Figure 9 and Figure 10The fourth connecting seat 84 is C-shaped, the fourth connecting seat 84 is welded to the side wall of the base 41, the fifth connecting seat 86 is welded to the inner side of the fourth connecting seat 84, the lifting rod 85 is passed through the fourth connecting seat 84 and the fifth connecting seat 86 and can move up and down in the vertical direction on the fourth connecting seat 84 and the fifth connecting seat 86; the top end of the lifting rod 85 contacts the fifth wedge surface 832; the compression spring 87 is sleeved on the lifting rod 85, the top end of the compression spring 87 is welded to the outer wall of the lifting rod 85, and the bottom end is welded to the top wall of the fifth connecting seat 86; the electromagnet 88 is fixedly connected to the bottom wall of the lifting rod 85 by screws.

[0097] When locked, the first drive cylinder 61 drives the adapter 62 to move upward, and the lifting seat 44 pushes the extrusion block 83 toward the side away from the support mechanism 5. Subsequently, the fifth wedge surface 832 pushes the lifting rod 85 downward until the electromagnet 88 contacts the bottom wall of the inner cavity of the concave channel steel 2. Then, the electromagnet 88 is energized to fix the electromagnet 88 to the concave channel steel 2, thereby fixing the base 41, the travel mechanism 3, etc. to the concave channel steel 2. During the downward movement of the lifting rod 85, the compression spring 87 is compressed. If the base 41, the travel mechanism 3, etc. no longer need to be fixed, the electromagnet 88 is de-energized. The compression spring 87 will drive the lifting rod 85 upward during the reset process, and the lifting rod 85 will push the extrusion block 83 toward the side close to the support mechanism 5.

[0098] S4: Fix the support base 18 on the auxiliary construction equipment, and start to build the grid structure with the support base 18 as the initial overlap point until the grid structure is completed;

[0099] During construction, auxiliary construction equipment is placed in the concave channel steel 2 at intervals, and the electromagnet 88 in the locking assembly 8 is adsorbed on the concave channel steel 2 to fix the walking mechanism 3 on the concave channel steel 2. Subsequently, the support seat 18 is overlapped on the topmost support column 51. Subsequently, the grid structure is built with the support seat 18 as the initial overlap point. After the construction is completed, in the grid structure, an upper chord ball 15 without a support seat 18 is left between the two adjacent support seats 18 on the same side track.

[0100] S5: Release the locking assembly 8 from the walking mechanism 3, that is, after the electromagnet 88 is powered off, the walking mechanism 3 drives the entire construction auxiliary equipment to move along the guide rail, and the grid structure moves with the construction auxiliary equipment until the grid structure moves to the top of the skylight 12.

[0101] S6: Lower the grid structure until the support base 18 is overlapped on the roof 1. S6 includes the following steps:

[0102] S61: Shorten the overall height of construction auxiliary equipment;

[0103] The process of shortening the auxiliary equipment is as follows: first, the first driving cylinder 61 drives the adapter 62 to move upward. During the upward movement of the adapter 62, the electromagnet 88 moves downward, and the electromagnet 88 is energized, so that the electromagnet 88 can be fixed on the concave channel steel 2. When the adapter 62 drives the electromagnet 88 to contact the concave channel steel 2, the clamping plate 64 moves with the adapter 62 to the same height as the plug hole 512 on the support column 51 to be fixed. Then, the second driving cylinder 63 drives the clamping plate 64 to be inserted into the plug hole 512 to fix the support column 51 to be fixed; then, the drive The two pushing seats 42 move in the direction away from each other, the lifting seat 44 and the bottom support column 51 move downward synchronously, and then the picking assembly 7 pushes the bottom support column 51 onto the roof 1; finally, the first oil cylinder 43 drives the two pushing seats 42 to move toward the side close to each other, so as to drive the lifting seat 44 to reset upward, and then the first driving cylinder 61 drives the support column 51 fixed with the splint 64 to move downward, thereby driving the supporting mechanism 5 and the grid structure as a whole to move downward until the support column 51 fixed with the splint 64 is overlapped on the lifting seat 44.

[0104] S62 : Repeat S1 until the topmost support column 51 is connected to the lifting base 44 .

[0105] S63: Reference Figure 11 and Figure 12 , remove the concave channel steel 2 between the two construction auxiliary equipment to form a jacking operation area; thus, the upper chord ball 15 between the two adjacent support seats 18 that is not connected to the support seat 18 will be located directly above the jacking operation area;

[0106] When removing the concave channel steel 2 , the pin 212 is pulled out from the pin hole 22 and then the fixing seat 211 is removed.

[0107] S64: Reference Figure 11 and Figure 12 , place the jack 9 in the jacking operation area, and make the jack 9 contact the upper chord ball 15 between two adjacent support seats 18 that are not connected to the support seat 18 after extension.

[0108] S65: Transferring the force of the grid structure to the jack 9;

[0109] When the lifting seat 44 moves downward, the support mechanism 5 moves downward with the lifting seat 44, and the upper string ball 15 that is not connected to the support seat 18 will be connected to the jack 9, so that the force of the truss structure is concentrated on the jack 9. Then the lifting seat 44 continues to move downward until the support column 51 on the lifting seat 44 is separated from the support seat 18.

[0110] S66: Remove the auxiliary construction equipment and the concave channel steel 2 used to support the auxiliary construction equipment. Before removing the auxiliary construction equipment, it is necessary to first turn off the power to the electromagnet 88, and then the auxiliary construction equipment can be removed.

[0111] S67: The jacks 9 drive the grid structure to move downward until the support base 18 is connected to the prism 11; there are multiple jacks 9, and the multiple jacks 9 are connected to the same controller. Under the control of the controller, the multiple jacks 9 can move downward synchronously.

[0112] S68: After the jack 9 is further retracted, the jack 9 is separated from the upper ball 15 on which the support seat 18 is not installed, and then the jack 9 is removed.

[0113] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
