Description

Technical Field

[0001] The invention belongs to the field of steel structure buildings, and particularly relates to a sliding support system for a steel roof structure and a construction method thereof. Background Art

[0002] A steel structure roof system building is a roof system that uses steel structures as main components and is built on the top of a building. Its main characteristics are light weight, high strength, corrosion resistance, good durability, and convenient construction. Steel structure roof system buildings can be applied to various types of buildings, such as factories, shopping malls, stadiums, exhibition centers, etc. Their use can greatly shorten the construction period, reduce the construction cost, and improve the safety and reliability of the building. In addition, steel structure roof system buildings can also achieve more unique building forms through design and structural innovations, bringing more changes and aesthetic feelings to the urban building landscape.

[0003] The roof structure of a stadium is an important architectural form that reflects large-span steel structures. To ensure that the strength, deformation, and stability of the structure and components during the hoisting process meet the requirements of relevant specifications, necessary temporary supports are set according to the characteristics of the roof steel structure and the force analysis and calculation, so that the structure during the installation process can independently form a spatially stable structure system and meet the strength and stability under the temporary supports. The temporary support system in the related technology uses a sliding falsework and falsework formwork. The sliding falsework is pushed by a jacking mechanism to move the sliding falsework to the corresponding position, and the arch beam of the steel roof is assembled through the falsework formwork to complete the operation of the temporary support. Since the steel structure roof applied to buildings such as stadiums has the characteristics of large coverage area, large installation span, special-shaped components, heavy components, and a large number of components, for a steel roof structure with a span exceeding 100m, the falsework formwork needs to bear the gravity load generated by the arch beam and the horizontal thrust generated by the arch beam during the support process of the steel roof structure. Since the falsework formwork structure in the related technology only makes line contact with the arch beam, and the falsework formwork and falsework columns in the related technology do not have the function of adjusting the support angle according to the position or arch shape of the arch beam, the support stability of the falsework formwork for the arch beam and the stress-bearing strength are relatively poor; the falsework formwork in the related technology limits the edge position of the arch beam through 2 baffles to prevent the separation and cooperation between the arch beam and the falsework formwork, but there is no distance adjustment mechanism between the baffle and the falsework formwork, and the falsework formwork can adapt to the arch beam structure with a width smaller than the falsework formwork, resulting in the need for repeated disassembly during the support process of the falsework formwork for various arch beams, thereby affecting the construction efficiency and construction progress.

[0047] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0048] A steel roof structure sliding support system, as Figure 2-3 shown, includes a support platform 101, a support structure, an adjustable support plate mechanism, an angle adjustment mechanism, a jacking mechanism, a sliding support base, two falsework form support mechanisms, and two guiding slide rails 601;

[0049] The sliding support base is slidably connected to the two guiding slide rails 601. One end of the output end of the jacking mechanism is connected to the fixed end, and the other end of the jacking mechanism is connected to the sliding support base. One end of the support structure is detachably connected to the upper end surface of the sliding support base, and the other end of the support structure is detachably connected to the support platform 101. In this embodiment, the support structure is a standard section, and the jacking mechanism is a jacking cylinder, which is not shown in the drawings;

[0050] The adjustable support plate mechanism and the two falsework form support mechanisms are both arranged on the upper end surface of the support platform 101, and the adjustable support plate mechanism is arranged between the two falsework form support mechanisms. In this embodiment, first mounting plates for connecting the tops of the support structures are provided at both the left and right ends of the support platform 101, and second mounting plates for connecting the bottoms of the support structures are provided at both the left and right ends of the first sliding base 501. Two oblong holes are provided on both the first mounting plate and the second mounting plate.

[0051] The adjustable support plate mechanism includes an arch beam support plate 301, a rotating rod 302, a rotating sleeve, two first fixed bases 303 and four auxiliary support structures. The rotating sleeve is integrally connected to the arch beam support plate 301. The rotating sleeve is rotatably arranged on the rotating rod 302. The two first fixed bases 303 are connected to the upper end surface of the support platform 101 by rivets. The two first fixed bases 303 are symmetrically arranged at the ends of the rotating rod 302. Two auxiliary support structures are correspondingly arranged on each first fixed base 303. The two auxiliary support structures are arranged on the opposite sides of the rotating rod 302. The angle adjustment mechanism is used to adjust the angle of the arch beam support plate 301. The arch beam is supported by the arch beam support of the adjustable support plate mechanism and the two jig templates 203, so as to realize the support of the arch beam 10 in the way of "point + surface", effectively avoiding the unstable situation when the support system supports the arch beam 10. In this embodiment, the auxiliary support structure includes an L-shaped fixed seat, a second inclined support plate 304 and two first rib plates. One end of the L-shaped fixed seat is connected to the first fixed base 303 by bolts, and the other end of the L-shaped fixed seat is connected to the support platform 101 by bolts. The second inclined support plate 304 is welded to the outside of the L-shaped fixed seat. The two first rib plates are arranged between the L-shaped fixed seat and the second inclined support plate 304. The two first rib plates are used to improve the stress-bearing strength of the auxiliary support structure in the inclined direction.

[0052] As Figure 4 shown, the jig template support mechanism includes a second fixed base 201, a jig template 203, a distance adjustment mechanism 204, two limit baffle structures 202 and two first inclined support plates 205. The second fixed base 201 is welded to the upper end surface of the support platform 101. The jig template 203 is arranged on the top of the second fixed base 201. The two limit baffle structures 202 are both arranged outside the jig template 203. The limit baffle structures 202 are connected to the second fixed base 201 through the distance adjustment mechanism 204. The two first inclined support plates 205 are symmetrically arranged on both sides of the second fixed base 201. The two first inclined support plates 205 are arranged on the opposite sides of the rotating rod 302. The top of the jig template 203 can cooperate with the arch beam 10, and the limit baffle structures 202 can limit the outside of the arch beam 10. By adjusting the distance between the limit baffle structures 202 and the second fixed base 201 through the distance adjustment mechanism, the support system can be adapted to a variety of arch beams. In this embodiment, the distance adjustment mechanism 204 includes two distance adjustment bolts. The two distance adjustment bolts penetrate through the bottom of the limit baffle structure 202, and the threaded parts of the distance adjustment bolts are connected to the second fixed base 201. In this embodiment, as Figure 4As shown, the limit baffle structure 202 includes a triangular limit plate frame, a connecting plate, and five second rib plates 2021. Three second rib plates 2021 are arranged and welded inside the triangular limit plate frame. Two second rib plates 2021 are symmetrically welded diagonally at the bottom inside the triangular limit plate frame. The connecting plate is welded to the bottom outside of the triangular limit plate frame. Two adjusting bolts penetrate through the connecting plate. A rubber pad is arranged at the position where the triangular limit plate frame contacts the arch beam, which plays a role in anti-slip and shock absorption for the arch beam through the rubber pad.

[0053] As Figure 5-7 shown, the angle adjusting mechanism includes two adjusting screws 306 and two support rods 305. There are grooves on the upper end surface of the support platform 101. The two adjusting screws 306 are arranged side by side in the grooves. The adjusting screws 306 are rotatably connected to the support platform 101 through two bearings. The screwing parts of the adjusting screws 306 are arranged outside the support platform 101; As Figure 7 shown, the two support rods 305 are arranged crosswise. One end of the support rod 305 is connected to the arch beam support plate 301 through a hinge seat 3051, and the other end of the support rod 305 is connected to the adjusting screw 306 through a threaded sleeve 3061. Through the two adjusting screws 306 and the two support rods 305 of the angle adjusting mechanism, multi-angle adjustment of the arch beam support plate 301 is realized, so that the support rod 305 always maintains a vertical state with the stress surface of the support plate, thereby improving the support stability and effectively dispersing the diagonal stress of the support plate. The crosswise arrangement of the two support rods 305 can improve the support stability.

[0054] As Figure 8 shown, this embodiment further includes a guiding mechanism including two guiding roller structures and two roller chute structures 403 that can cooperate with the guiding roller structures. The cross-section of the support platform 101 is C-shaped. The two guiding roller structures and the two roller chute structures 403 are symmetrically arranged on the lower end surface inside the support platform 101. The top of the guiding roller structure is slidably connected to the support platform 101. A roller chute structure 403 is correspondingly arranged behind each guiding roller structure. Through the guiding roller 402 structure and the roller chute structure 403 of the guiding mechanism, when the two support platforms 101 are docked, the stability and accuracy of the docking can be ensured, and when the docking is not carried out, the roller chute structure 403 can play a role in accommodating the guiding roller 402 structure.

[0055] The guiding roller structure includes a roller bracket 401 and two rows of guiding rollers 402. The two rows of guiding rollers 402 are symmetrically arranged in the through groove of the roller bracket 401. The top of the roller bracket 401 is slidably connected to a T-shaped chute preset on the lower end face of the support platform 101 through a T-shaped slide rail. When the roller bracket 401 is completely removed from the roller chute structure 403, the roller bracket 401 realizes the limit fixation between the support platform 101 and the roller bracket 401 through a positioning pin; inside each guiding roller 402 in the through groove, a roller pressing mechanism is correspondingly arranged. The roller pressing mechanism includes an arc plate that can cooperate with the guiding roller 402 and a pre-tightening spring. One end of the pre-tightening spring abuts against the outer end face of the arc plate, and the other end is connected to the roller bracket 401. Through the roller pressing mechanism, the guiding roller 402 is always kept in a pressed state, effectively preventing wear at the axis position of the guiding roller 402, resulting in the inability of the guiding roller 402 to closely fit the inner wall of the roller chute structure 403, and further leading to the problem of reduced guiding accuracy.

[0056] The sliding support base includes a first sliding base 501, a second sliding base 502 and two elastic limiting structures. Two rows of first sliding rollers that can cooperate with the guiding slide rail 601 are symmetrically arranged on the lower end face of the first sliding base 501. Two rows of second sliding rollers that can cooperate with the guiding slide rail 601 are symmetrically arranged on the upper end face of the second sliding base 502. The two elastic limiting structures are used to realize the connection and fixation between the first sliding base 501 and the second sliding base 502. The two elastic limiting structures are symmetrically arranged between the two guiding slide rails 601. The first sliding base 501 is connected to the output end of the pushing mechanism. By symmetrically arranging the two elastic limiting structures between the two guiding slide rails 601, it can play a limiting role between the first sliding base 501 and the second sliding base 502, and the elastic limiting structure can play a shock-absorbing role to avoid the problem that when foreign objects or damage occur between the sliding rollers and the guiding slide rail 601, the sliding support base loses its function of sliding on the guiding slide rail 601, thereby affecting the construction progress; in this embodiment, the elastic limiting structure includes a guiding support rod 701, a return spring 702 and a locking nut 703. The top of the guiding support rod 701 is fixedly connected to the lower end face of the first sliding base 501. The guiding support rod 701 penetrates through the second sliding base 502. The locking nut 703 is arranged at the bottom of the guiding support rod 701. The return spring 702 is sleeved outside the guiding support rod 701. One end of the return spring 702 is on the lower end face of the second sliding base 502, and the other end of the return spring 702 abuts against the locking nut 703.

After assembly, the bottom of the support structure is connected to the sliding support base through multiple bolts, and the top of the support structure is connected to the support platform 101 through multiple bolts.

[0062] Step 4: Connect and fix the sliding support base to the 2 guiding rails 601, and connect the output end of the jacking mechanism to the sliding support base of the slider.

[0063] Step 5: The output end of the jacking mechanism pushes the sliding support base, and then pushes the adjustable support plate mechanism and the 2 formwork support mechanisms, and pushes the adjustable support plate mechanism and the 2 formwork support mechanisms to the assembly position with the arch beam 10.

[0064] Step 6: Connect the guide rail mechanisms of the 2 support platforms 101 to each other.

[0065] Step 7: Adjust the angle of the arch beam support plate 301 through the angle adjustment mechanism so that the arch beam support plate 301 can be completely attached to the arch beam 10, and adjust until the 2 support rods 305 of the angle adjustment mechanism are perpendicular to the arch beam support plate 301 to ensure the completion of the assembly of the formwork 203 of the 2 formwork support mechanisms with the arch beam 10.

[0066] Step 8: Lock the distance adjustment mechanism 204 of the 2 limit baffle structures 202 to realize the clamping and fixing of the outside of the arch beam 10.

[0067] Step 9: Assemble or weld the arch beam 10 on the 2 support platforms 101.

[0068] Step 10:
