Description

Technical Field

[0001] This invention relates to the field of explosion venting plant construction technology, and in particular to a hoisting construction method for modular explosion venting panels. Background Technology

[0002] Workplace safety has always been a key focus for factories and is directly linked to the personal safety of workers. The safety of factory buildings is a key aspect of building safety. Although factory explosions are rare, minimizing casualties and property damage in the event of an explosion is crucial. Currently, installing fiber-reinforced cement explosion-proof panels is an effective method. Generally, fiber-reinforced cement explosion-proof panels are installed one by one, with the following installation sequence: measurement and layout – installation of metal supports – installation of longitudinal light steel keel and beams in the wall – installation of longitudinal and transverse square steel pipes – installation of inner fiber-reinforced cement panels – rock wool board filling – installation of outer fiber-reinforced cement panels. Existing installation processes can meet construction quality requirements, but the installation speed is too slow and unsuitable for projects with tight schedules. Therefore, this invention was developed. Summary of the Invention

[0003] This application provides a hoisting construction method for modular explosion-proof panels to solve the problem.

[0004] To solve the above-mentioned technical problems, this application provides a hoisting construction method for a building using modular explosion-proof panels, including: Step 1, purlin installation.

[0005] According to the purlin layout diagram, a 25t truck crane is used to install the purlins, then the tie rods and diagonal supports are installed. After the tie rods and diagonal supports are installed, the roof panels are hoisted with slings and hoisting brackets, and explosion relief bolts are installed. Multiple traction slings are installed on the inside of the roof panels, and finally the ridge plate is installed between the roof panels.

[0006] Step 2: Fabrication of Module Explosion-Relief Board

[0007] Weld the explosion-proof board keel according to the size of the module explosion-proof board. When the module explosion-proof board encounters door or window openings, leave space for the door or window size and cut and arrange it. Then apply a layer of weather-resistant adhesive to one side of the welded explosion-proof board keel and lay the inner wall panel on the explosion-proof board keel. Fill the explosion-proof board keel with rock wool board perpendicular to the keel. Apply a layer of weather-resistant adhesive to the other side of the explosion-proof board keel and lay the outer wall panel on the explosion-proof board keel.

[0008] Step 3, Installation of longitudinal and transverse keel

[0009] Multiple connecting plates are installed on the sides of the concrete beams, the eaves of the inter-story beams, and the concrete sills on the first floor. Square steel pipes are welded to the outside of the connecting plates. The square steel pipes are laid along the length of the concrete beams. Multiple M12 expansion bolts are installed on the square steel pipe connecting plates. The spacing between adjacent connecting plates is 800mm.

[0010] Step 4: Hoisting, aligning, and welding of the module explosion relief plate.

[0011] A 25t truck crane was used to lift the modular explosion relief panels, and an articulated boom lift was used to lift the installation workers. The modular explosion relief panels were installed sequentially from the lower to the upper floors. During the hoisting, the bottom modular explosion relief panels were first fixed, leveled, and plumbed. Then, the bottom modular explosion relief panels were welded to the pre-fixed square steel pipes. The bottom keel of the bottom modular explosion relief panels was welded to the connecting plate on the platform. After the bottom modular explosion relief panels were installed, the remaining modular explosion relief panels were installed sequentially, using the same method as the bottom modular explosion relief panels.

[0012] Step 5, Treatment of board gaps

[0013] If the gap between the boards is greater than 2mm, first fill it with a polyurethane foam with a fire rating of Class A. After the foam has dried and filled the gap completely, fill it with putty. The putty filling is done in three layers: base layer, intermediate layer and top layer.

[0014] In some embodiments of this application, when installing the purlins in step one, the horizontal height difference and the slope height difference of the purlins are not greater than 5mm.

[0015] In some embodiments of this application, in step two, multiple M4 self-tapping screws are provided on the inner wall panel and the outer wall panel, and the multiple M4 self-tapping screws extend into the explosion vent plate keel, with a spacing of 150mm between adjacent M4 self-tapping screws.

[0016] In some embodiments of this application, both the inner wall panel and the outer wall panel are fiber-reinforced cement boards, and the outer wall panel is configured as a double layer with the two layers of outer wall panels arranged in a staggered manner.

[0017] In some embodiments of this application, the square steel tube has dimensions of 60*60*2.5mm, and the spacing between adjacent expansion bolts is 800mm.

[0018] In some embodiments of this application, the size of the module explosion relief plate is 2.1*3.8m or 4.8*6.18m.

[0019] In some embodiments of this application, the thickness of the rock wool board is the same as the thickness of the explosion venting keel.

[0020] Compared with the prior art, the present invention has the following features and beneficial effects:

[0021] This invention improves existing construction methods for explosion-proof buildings, creating a new method that includes roof construction, modular explosion-proof panel fabrication, longitudinal and transverse keel installation, modular explosion-proof panel hoisting, alignment and welding, and panel gap treatment. Before installation, the explosion-proof panels are pre-processed, and connecting plates are installed on the existing structure to form modular explosion-proof panels. Then, the entire assembly is hoisted according to the method described in this invention. This method can accelerate construction progress, shorten the construction period, reduce labor input, decrease the frequency of high-altitude operations, and improve construction safety. Its widespread use is expected to produce good results. Attached Figure Description

[0034] like Figure 1-7 As shown, according to some embodiments of this application, a hoisting construction method for a modular explosion-proof panel building includes: Step 1, installing purlins 100.

[0035] According to the purlin 100 layout drawing, a 25t truck crane is used to install purlin 100, then tie rods and diagonal supports are installed. After the tie rods and diagonal supports are installed, the roof panels are hoisted with slings and hoisting brackets, and explosion relief bolts are installed. Multiple traction rigging is installed on the inside of the roof panels, and finally the ridge plate is installed between the roof panels.

[0036] Step 2: Fabrication of the Module Explosion-Relief Board 200

[0037] Weld the explosion relief plate keel 220 according to the dimensions of the module explosion relief plate 200. When the module explosion relief plate 200 encounters door or window openings, leave space for the dimensions of the door or window and cut and arrange it. Then, apply a layer of weather-resistant adhesive to one side of the welded explosion relief plate keel 220 and lay the inner wall panel 210 on the explosion relief plate keel 220. Fill the explosion relief plate keel 220 with rock wool board 230 perpendicular to the keel. Apply a layer of weather-resistant adhesive to the other side of the explosion relief plate keel 220 and lay the outer wall panel 240 on the explosion relief plate keel 220.

[0038] Step 3, Installation of longitudinal and transverse keel

[0039] Multiple connecting plates 320 are installed on the side of the concrete beam 300, the eaves of the inter-story beam, and the first-floor concrete sill 400. Square steel pipes 310 are welded to the outside of the connecting plates 320. The square steel pipes 310 are laid along the length of the concrete beam 300. Multiple M12 expansion bolts are installed on the connecting plates 320 of the square steel pipes 310. The spacing between adjacent connecting plates 320 is 800mm.

[0040] Step 4: Hoisting, aligning, and welding of the module explosion relief plate 200.

[0041] A 25t truck crane was used to lift the modular explosion relief plate 200, and an articulated boom lift was used to lift the installation workers. The modular explosion relief plates 200 were installed sequentially from the lower to the upper floors. During the hoisting, the bottom modular explosion relief plate 200 was fixed first. After leveling and plumbing, the bottom modular explosion relief plate 200 was welded to the pre-fixed square steel pipe 310. The bottom keel of the bottom modular explosion relief plate 200 was welded to the connecting plate 320 on the sill. After the bottom modular explosion relief plate 200 was installed, the remaining modular explosion relief plates 200 were installed sequentially, using the same method as the bottom modular explosion relief plate 200.

[0042] Step 5, Treatment of board gaps

[0043] If the gap between the boards is greater than 2mm, first fill it with a polyurethane foam with a fire rating of Class A. After the foam has dried and filled the gap completely, fill it with putty. The putty filling is done in three layers: base layer, intermediate layer and top layer.

[0044] According to some embodiments of this application, when installing the purlin 100 in step one, the horizontal height difference and the slope height difference of the purlin 100 are not greater than 5mm.

[0045] According to some embodiments of this application, in step two, multiple M4 self-tapping screws are provided on the inner wall panel 210 and the outer wall panel 240, and the multiple M4 self-tapping screws extend into the explosion vent plate keel 220, with a spacing of 150mm between adjacent M4 self-tapping screws.

[0046] According to some embodiments of this application, both the inner wall panel 210 and the outer wall panel 240 are fiber-reinforced cement boards, and the outer wall panel 240 is configured as a double layer with the two layers of outer wall panels 240 arranged in a staggered manner.

[0047] According to some embodiments of this application, the square steel tube 310 has dimensions of 60*60*2.5mm, and the spacing between adjacent expansion bolts is 800mm.

[0048] According to some embodiments of this application, the size of the module explosion relief plate 200 is 2.1*3.8m or 4.8*6.18m.

[0049] According to some embodiments of this application, the thickness of the rock wool board 230 is the same as the thickness of the explosion venting keel 220.

[0050] According to some embodiments of this application, in step one, the purlin 100 is a Q355B galvanized purlin 100 with specifications of C220×75×20×2.5. First, according to the purlin 100 layout diagram, a center line is marked on the purlin 100 support, and a horizontal line is drawn between the ridge and the eaves to ensure that the purlin 100 is straight in the transverse and sloping directions when installed. When installing the purlin 100, the horizontal height difference and sloping height difference should be controlled within 5mm. A 25t truck crane is used to hoist the purlin 100, and only one purlin is hoisted at a time. The next purlin 100 can only be hoisted after the purlin 100 is fixed with bolts. The bolts securing the purlins 100 must be tightened securely; no bolts should be missing or loose. The tie rods are made of A14 round steel, and the diagonal braces are made of A14 round steel with matching A32×2.5 round tubing. During installation, adjust the straightness and spacing of the purlins 100 as needed, then tighten the bolts on the tie rods and braces. Adjacent purlins 100 at the ridge are secured with self-tapping screws using C14×60×20×2.0 connectors, one every 1000mm. The roof panel is 21m long, 0.93m wide, and 0.12m thick. Due to the roof surface... Due to the large length of the roof panels, direct hoisting with slings would cause damage and deformation. Before hoisting, a hoisting support should be made using channel steel. The roof panels should be hung on the support with slings. Before hoisting, a straight line parallel to the ridge should be drawn at the eaves and its perpendicularity to the gable wall should be measured. The front and back ends of the panels should be aligned with the eaves line, and the peak of the panels should be perpendicular to the eaves line, without any tilting. When installing the explosion-proof bolts, drill a hole slightly larger than the diameter of the explosion-proof bolt at the corresponding position, and drive the bolt into the hole with a rubber hammer and tighten it. Each explosion-proof roof panel should be equipped with 3 traction cables, with a length of 0.9m to 1m. Place the nut of the winch into the hole drilled in the purlin 100mm, insert the iron ring at one end of the traction winch into the nut hole and tighten the nut, and fix the other end under the roof panel in the same way; when installing the ridge panel, first fill the gap between the two ridge panels with expanding foam, install the ridge tile on the ridge, and fix the ridge tile to the corrugation of the roof panel with rivets. Apply weather-resistant sealant to the joints between ridge tiles and between ridge tiles and roof panels to prevent water leakage.

[0051] According to some embodiments of this application, in step two, the explosion relief plate keel 220 is welded by gas-shielded arc welding. After welding is completed, the welder should clean the weld slag and spatter on the weld surface and check the appearance quality of the weld.

[0052] In summary, this invention relates to the field of explosion venting plant construction technology, and discloses a hoisting construction method for modular explosion venting panels, including: purlin installation, modular explosion venting panel fabrication, longitudinal and transverse keel installation, modular explosion venting panel hoisting, alignment and welding, and panel gap treatment. Unlike the existing method of installing explosion venting panels piece by piece, this invention welds the explosion venting panel keel according to the size of the modular explosion venting panel. When the modular explosion venting panel encounters door or window openings, the dimensions of the door or window are left for installation, and the panels are cut and arranged. Then, a layer of weather-resistant adhesive is applied to one side of the welded explosion venting panel keel, and the inner wall panels are laid on the explosion venting panel keel. Rock wool boards are filled perpendicularly to the keel inside the explosion venting panel keel. A layer of weather-resistant adhesive is applied to the other side of the explosion venting panel keel, and the outer wall panels are laid on the explosion venting panel keel, thus improving the construction speed.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
