[0023] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] See Figure 1-28 , an embodiment of the present application provides an explosion-proof and pressure-relieving exterior wall construction method, comprising the following steps:

[0025] See Figure 1-24 Step 1: Fix the slide rail assembly on the building 1. The slide rail assembly defines a plurality of track grooves on the building 1, and each track groove extends in the vertical direction. Each track groove is used for the wall panels 5 of the explosion-proof and pressure relief outer wall to slide in from top to bottom to realize the splicing of each wall panel 5.

[0026] In the above steps, refer to Figure 9-12 21-24, the slide rail assembly can include multiple sets of slide rails 2. Each set of slide rails 2 can be arranged horizontally. Each set of slide rails 2 can include two slide rails 2. The two slide rails 2 in each set of slide rails 2 can be arranged vertically. The two slide rails 2 can each have an L-shaped cross-section and can be symmetrically arranged so that each set of slide rails 2 defines multiple track grooves on the building 1. In addition, the two slide rails 2 in each set of slide rails 2 can each be composed of a full-length slide rail or can be spliced together from multiple slide rail segments.

[0027] See Figures 21-24 In order to fix each set of slide rails 2 on the building 1, the bracket assembly can be pre-buried in the building 1, and the slide rail assembly can be fixed on the building 1 through the bracket assembly.

[0028] Among them, see Figure 17-20The bracket assembly may include multiple groups of brackets, each group of brackets may be arranged in a horizontal direction, each group of brackets may include multiple brackets, and each bracket in each group of brackets may be arranged in a vertical direction, so that each slide rail 2 in the slide rail assembly can be fixed on the building 1 through each group of brackets.

[0029] Further, see Figure 1-4 , 17-20, the bracket can be an L-shaped bracket 3 having a long side and a short side. The cross-sections of the long side and the short side can both be square. The long side can be a pre-embedded section, and the short side can be a horizontal section. In this case, when the L-shaped bracket 3 is pre-embedded in the building 1, the long side of the L-shaped bracket 3 can be perpendicular to the building 1, and the free end of the long side can be pre-embedded in the building 1. The short side of the L-shaped bracket 3 can extend horizontally and can have a gap between it and the building 1, so that the L-shaped bracket 3 is pre-embedded in the building 1 and the slide rail 2 can be clamped in the gap.

[0030] See Figure 5-8 , 17-20, the bracket can also be a T-shaped bracket 4, having a long side and a short side. The cross-sections of the long side and the two short sides can be square. The long side can be a pre-embedded section, and the two short sides can be horizontal sections. In this case, when the T-shaped bracket 4 is pre-embedded in the building 1, the long side of the T-shaped bracket 4 can be perpendicular to the building 1, and the free end of the long side can be pre-embedded in the building 1. The two short sides of the T-shaped bracket 4 can both extend in the horizontal direction and can have a gap between them and the building 1, so that the T-shaped bracket 4 is pre-embedded in the building 1 and the slide rail 2 can be clamped in the gap.

[0031] See Figure 17-20 Optionally, the two groups of brackets at both ends in the horizontal direction each use a plurality of L-shaped brackets 3, and each group of brackets in the middle in the horizontal direction each use a plurality of T-shaped brackets 4.

[0032] Further, see Figure 9-12 The outer side surface of the L-shaped cross section of each slide rail 2 is provided with an L-shaped groove 20, so that the L-shaped bracket 3 and the T-shaped bracket 4 are respectively embedded in the L-shaped groove 20 when the slide rail 2 is clamped in the gap.

[0033] Also, see Figure 1-12 The slide rails 2 may each be provided with a first locking hole 21, and the L-shaped bracket 3 and the T-shaped bracket 4 may each be provided with a second locking hole (30, 40), so that the slide rails 2 and the L-shaped bracket 3 and the T-shaped bracket 4 can be connected via a latch provided in the first locking hole 21 and the second locking hole (30, 40). The latch may be a self-locking latch.

[0034] Furthermore, the first locking holes 21 are provided at the top and bottom of each slide rail 2, and the second locking holes (30, 40) are provided on the two L-shaped brackets 3 and the T-shaped bracket 4 located at both ends in the vertical direction.

[0035] In addition, the inner side surface of the L-shaped cross section of each slide rail 2 can be provided with a locking groove 22 for the locking block 50 on each wall panel 5 to be locked in.

[0036] The above steps can be specifically as follows:

[0037] See Figure 17-20 , A. L-shaped bracket 3, T-shaped bracket 4 pre-embedded sub-steps:

[0038] 1) A professional surveyor shall determine the specific location based on the embedded center and elevation designed in the drawings.

[0039] 2) Place L-shaped bracket 3 and T-shaped bracket 4, measure the embedded length, horizontality and verticality of the bracket, and temporarily reinforce them as required.

[0040] 3) After the L-shaped bracket 3 and T-shaped bracket 4 are placed, the surveyor will adjust and check the embedded bracket. After verification that they meet the specification requirements, the L-shaped bracket 3 and T-shaped bracket 4 are welded firmly. At the same time, diagonal braces are welded in the vertical and horizontal directions for reinforcement.

[0041] 3) Concrete pouring.

[0042] In the above sub-steps, please note: when pre-embedding the L-shaped bracket 3 and the T-shaped bracket 4, pay attention to the direction of the short sides (relative to each other), otherwise they cannot be used later.

[0043] See Figures 21-24 , B. Slide rail 2 installation sub-steps:

[0044] 1) Use a crane to vertically lift the slide rail 2 to the specified height so that the top L-shaped groove 20 on the outside of the slide rail 2 is flush with the top of the embedded L-shaped bracket 3 and T-shaped bracket 4.

[0045] 2) Smoothly translate the slide rail 2 so that the L-shaped groove 20 is engaged with the L-shaped bracket 3 and the T-shaped bracket 4, and the first locking hole 21 of the slide rail 2 and the second locking holes (30, 40) of the L-shaped bracket 3 and the T-shaped bracket 4 are aligned.

[0046] 3) Align the first locking hole 21 of the slide rail 2, the second locking holes (30, 40) of the L-shaped bracket 3 and the T-shaped bracket 4, and insert the self-locking pins to lock and secure (a total of 8 self-locking pins on the upper and lower parts of the slide rail 2).

[0047] In the above sub-steps, please note: ① When hoisting the slide rail 2, be sure to pay attention to the installation mark direction to prevent the lock grooves 22 on the two slide rails 2 in the same set of slide rails 2 from being misaligned due to incorrect installation, resulting in rework.

[0048] ② When installing the self-locking latch, be sure to check whether it is locked into the annular groove (two ways to determine: listen to the sound when it is locked, and pull it outward)

[0049] See Figures 25-28 Step 2: Slide each wall panel 5 of the explosion-proof and pressure-relief exterior wall into each track groove in the vertical direction. There is a gap between each wall panel 5 and the inner wall of the track groove to form a pressure relief buffer space, and the joints of each wall panel 5 and the joints between the wall panel 5 and the building 1 are filled with soft colloid to form an explosion-proof and pressure-relief exterior wall.

[0050] In the above steps, each wallboard 5 of the explosion-proof and pressure-relieving outer wall can be 10CM thick and the gap can be 10mm±2mm.

[0051] Each wall panel 5 of the explosion-proof and pressure-relief outer wall may be provided with locking blocks 50 on both sides in the horizontal direction. The locking blocks 50 may be trapezoidal and may be snapped into the locking slots 22 to lock and fix the explosion-proof and pressure-relief outer wall.

[0052] The bottom and back of each wall panel 5 (the contact surface with the building 1) can be coated with self-adhesive glue, which can be 5 mm thick, so that the joints of each wall panel 5 and the joints between the wall panel 5 and the building 1 are filled with soft colloid.

[0053] The above steps can be specifically as follows:

[0054] See Figures 25-28 , C. Explosion-proof and pressure-relief exterior wall assembly sub-steps:

[0055] Lift each wall panel 5 of the explosion-proof and pressure-relief exterior wall to just above the track groove defined by two slide rails 2 in the same set of slide rails 2, slowly lower it to the lower end, and assemble it in the above manner.

[0056] In the above sub-steps, please note: ① Before hoisting each wall panel 5 of the explosion-proof and pressure relief exterior wall, the protective film on the outer surface of the self-adhesive glue (upper and lower surfaces, and the contact surface of the building 1) must be torn off to allow the wall panels 5 to be spliced together and the wall panels 5 to stick to the building 1 by themselves.

[0057] ② Before sliding each wall panel 5 of the explosion-proof and pressure relief outer wall into the track groove, the installation direction must be determined to prevent the self-adhesive glue from contacting the opposite surface of the building 1.

[0058] ③ Make sure that the two trapezoidal locking blocks 50 at the left and right ends of each wall panel 5 of the explosion-proof and pressure-relief outer wall are inserted into the locking grooves 22 of the slide rail 2.

[0059] In the construction method of the explosion-proof and pressure-relieving exterior wall of the present application, the L-shaped bracket 3 and the T-shaped bracket 4 are first pre-embedded in the corresponding positions during structural construction. The slide rail 2 is hoisted so that the L-shaped groove 20 on the slide rail 2 is combined with the L-shaped bracket 3 and the T-shaped bracket 4, and the first lock hole 21 is aligned with the second lock hole (30, 40). The self-locking pin is inserted to fix the L-shaped bracket 3, the T-shaped bracket 4, and the slide rail 2 into a whole. Each wall panel 5 of the explosion-proof and pressure-relieving exterior wall is hoisted to the position directly above the track groove defined by two slide rails 2 in the same group of slide rails 2, and then slowly lowered to slide to the lowest locking position.

[0060] The explosion-proof and pressure-relieving exterior wall construction method of this application has the following beneficial effects:

[0061] 1. Three-level buffer

[0062] 1) Self-buffering: The explosion-proof and pressure relief exterior wall is made of lightweight materials, so it has strong buffering properties.

[0063] 2) Space buffer: A 10mm gap (space) is left between the explosion-proof pressure relief outer wall and the outer fixings, which can effectively increase the pressure relief buffer space in the event of an explosion.

[0064] 3) Colloid cushioning: The splicing glue uses soft colloid, which greatly improves the cushioning performance.

[0065] 2. Quick installation (combination)

[0066] This construction method completely changes the complicated installation process steps of traditional explosion-proof and pressure relief exterior walls, achieving the effect of rapid installation.

[0067] 3. Self-adhesive splicing

[0068] The joint contact surfaces between each wall panel 5 of the explosion-proof and pressure relief exterior wall and the building 1, and between each wall panel 5 are all provided with 5mm self-adhesive glue, which will bond itself during installation. There is no need to seal the joints with glue after the splicing is completed as in traditional construction.

[0069] 4 Others

[0070] 1) Reduce pollution: This construction method reduces the generation of welding smoke, waste, etc.

[0071] 2) Reduce risks: Operators no longer need to perform tedious high-altitude operations, reducing the incidence of safety accidents.

[0072] 3) Cost reduction: The use of welding rods, sealants and other materials is reduced, and the labor force is reduced by about 36-43% compared with traditional construction processes. In addition, the cost of recycling materials (L-shaped bracket 3, T-shaped bracket 4, slide rail 2, self-locking pin) is reduced by about 21%.

[0073] The main application scope of the explosion-proof and pressure relief exterior wall construction method of this application: hazardous production workshops that require explosion relief for dust explosions and gas explosions, industrial and civil factory boiler rooms, power centers, high-energy explosives hazardous workshops, hazardous goods warehouses, etc.
