Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an anti-cracking reinforcement system and a construction method for a lightweight partition board. Background Art

[0002] With the development of the construction industry, lightweight partition boards are widely used in interior partition projects of modern buildings due to their light weight and quick construction. Before construction, the height, length and thickness of the lightweight partition wall are determined according to the design drawings and the actual on-site measurement data, and a detailed list of materials is provided to the manufacturer to facilitate the prefabrication of lightweight partition boards. Due to the limitations of transportation and on-site process, the width of lightweight partition boards will be limited, and there will be more board joints in the lightweight partition board walls during the actual wall panel installation. The conventional construction method is to improve the quality of the board joints by tongue-and-groove design on the board edges at the board joints during the installation stage of the lightweight partition boards, and embed mortar or other sealing and bonding materials during the installation process. On the other hand, after the installation of the lightweight partition boards is completed, the outside of the entire board joint is treated by applying adhesive mortar and adding mesh cloth.

[0003] However, in actual construction, the existing method for preventing cracking of the board seams of lightweight partition boards has the following problems: the use of traditional tongue-and-groove joints and the use of adhesive mortar and mesh cloth on the outside of the board seams, although it has a certain delaying effect on the cracking of the board seams, has not fundamentally solved the problem, especially during the period of use after the wall painting of the lightweight partition is completed, the cracking of the board seams can be said to be fatal, not only the safety of use function is greatly reduced, but also a large amount of maintenance costs are required in the later stage for treatment, especially in the case of large building spans, high floor heights, and large spaces, lightweight partition boards are prone to deformation, displacement, and cracking, and the quality of the board seams of lightweight partition boards is even more difficult to guarantee.

[0034] As attached Figure 1 ~Attached Figure 3As shown, a pair of reinforcing components 14 are provided at the joints between the first wall panel 5 and the adjacent middle wall panel 7, the joints between the two adjacent middle wall panels 7, and the joints between the rear wall panel 6 and the adjacent middle wall panel 7, and each pair of reinforcing components 14 are arranged opposite to each other and are respectively fixed to the lower surface of the top plate 1 and the floor 2, each reinforcing component 14 includes two V-shaped flat plates 15 with openings arranged opposite to each other, and a U-shaped clamping plate 16 is commonly fixed to the middle of the two V-shaped flat plates 15, and the inner sides of the back plates of the two U-shaped clamping plates 16 of each pair of reinforcing components 14 are respectively attached to the upper and lower surfaces of the joints between the corresponding first wall panel 5 and the adjacent middle wall panel 7. The inner sides of the two side panels of each U-shaped splint 16 are respectively fitted to the front and rear surfaces of the joint between the corresponding first wall panel 5 and the adjacent middle wall panel 7 or the front and rear surfaces of the joint between the corresponding two adjacent middle wall panels 7 or the front and rear surfaces of the joint between the corresponding rear wall panel 6 and the adjacent middle wall panel 7, and a staple 17 is vertically fixed at the vertex of the inner surface of each V-shaped flat plate 15, and each staple 17 is inserted in the corresponding first wall panel 5 or the corresponding middle wall panel 7 or the corresponding rear wall panel 6.

[0035] The reinforcement component 14 is arranged at the joint of the lightweight partition board, and through the combined design of the V-shaped flat plate 15 and the U-shaped clamp plate 16, the rigidity and stability of the joint of the lightweight partition board are increased, effectively preventing cracking at the joint; the staples 17 further fix the U-shaped clamp plate 16 to ensure the firmness of the reinforcement component 14.

[0048] A construction method for a crack prevention reinforcement system for a lightweight partition board, the construction method is implemented by the following steps:

[0049] Step 1: After the construction of the first steel column 3 and the second steel column 4 is completed, the installation axis, edge line and control line of the lightweight partition wall are popped up on the ground;

[0050] Step 2: Weld three round hexagonal long nuts III 10 at the side of the first steel column 3 close to the lightweight partition wall according to the designed position to ensure that the welding is firm and the position is accurate;

[0051] Step 3: Place the first wall panel 5 at the predetermined position, ensure that the three reserved screw holes of the first wall panel 5 are aligned one by one with the three round hexagonal long nuts III10 on the first steel column 3, prepare a vertical connecting plate 19, take three screw sections 8 with round hexagonal long nuts I9 fixed at the tail ends, insert them into the three fixing holes 20 of the vertical connecting plate 19 in sequence, and insert the three screw sections 8 into the three reserved screw holes one by one from the side of the first wall panel 5 away from the first steel column 3, use a tool to rotate the round hexagonal long nut I9 at the tail end of each screw section 8 so that the head end of each screw section 8 is inserted into the corresponding round hexagonal long nut III10, and the round hexagonal long nut I9 on each screw section 8 clamps the vertical connecting plate 19 and the first wall panel 5 together, ensuring that each screw section 8 is firmly installed without looseness;

[0052] Step 4: Place the first intermediate wall panel 7 next to the first wall panel 5, ensure that the three reserved screw holes of the first intermediate wall panel 7 are aligned one by one with the three screw sections 8 on the first wall panel 5, prepare another vertical connecting plate 19, take another three screw sections 8 with round hexagonal long nuts II fixed at the tail ends, insert them into the three fixing holes 20 of the vertical connecting plate 19 in sequence, and insert the three screw sections 8 into the three reserved screw holes one by one from the side of the first intermediate wall panel 7 away from the first steel column 3, use a tool to rotate the round hexagonal long nut II at the tail end of each screw section 8 so that the head end of each screw section 8 is inserted into the corresponding round hexagonal long nut I9, and the round hexagonal long nut II on each screw section 8 clamps the vertical connecting plate 19 and the first intermediate wall panel 7 together, and ensure that each screw section 8 is firmly installed without looseness;

[0053] Step 5: Place the second intermediate wall panel 7 next to the first intermediate wall panel 7, ensure that the three reserved screw holes of the second intermediate wall panel 7 are aligned one by one with the three screw sections 8 on the first intermediate wall panel 7, prepare another vertical connecting plate 19, take another three sections of screw sections 8 with the front U-shaped iron sheet 11 and the round hexagonal bolt head 12 fixed to the tail ends, insert them into the three fixing holes 20 of the vertical connecting plate 19 in sequence, and move the three screw sections 8 away from the intermediate wall panel 7 and the first steel column 3 One side of the U-shaped iron sheet 11 is inserted into the three reserved screw holes one by one, and the round hexagonal bolt head 12 at the tail end of each screw section 8 is rotated by a tool so that the head end of each screw section 8 is inserted into the round hexagonal long nut II of the corresponding front middle wall panel 7. At this time, the round hexagonal bolt head 12 on each screw section 8 clamps the vertical connection plate 19 and the second middle wall panel 7 together, and the back plate of each front U-shaped iron sheet 11 is horizontally clamped between the inner side of the corresponding round hexagonal bolt head 12 and the vertical connection plate 19;

[0055] Step 7: After the four wall panels are installed, mortar is injected through each grouting hole 24. The mortar flows into and fills each reserved screw channel through the connecting grouting channel 23, thereby strengthening the fastening force of the screw section 8 on the wall panel and solving the rust prevention and durability problems of the screw section 8. During the grouting process, pay attention to observing the overflow hole 25 to ensure that the mortar is fully filled, thereby completing the construction of the anti-cracking reinforcement system; the existing lightweight partition board joint anti-cracking construction method is overcome. The delay effect is limited and the problem of board joint cracking cannot be fundamentally solved, especially during the use period after the wall surface of the lightweight partition wall is painted. The cracking of the board joint seriously affects the safe use function and requires a lot of maintenance costs.
