[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. The place where the construction work is done is called "construction site" or "construction site", also called construction site.
[0003] Construction is a production activity that people use various building materials, mechanical equipment and equipment to build various building products in a certain space and time according to a specific design blueprint. It includes the entire production process from construction preparation, groundbreaking to project completion acceptance. In this process, construction preparation, construction organization design and management, earthwork engineering, blasting engineering, foundation engineering, steel engineering, formwork engineering, scaffolding engineering, concrete engineering, prestressed concrete engineering, masonry engineering, steel structure engineering, wood structure engineering, structural installation engineering and other work will be carried out.
[0004] Construction is a technically complex production process that requires construction workers to use their intelligence and creatively apply theories of materials, mechanics, structure, and technology to solve technical problems that arise during construction and ensure project quality and construction safety.
[0005] One component of the composite floor is the cast-in-place concrete layer, whose thickness varies with the span of the floor, but should be at least equal to the thickness of the prefabricated thin plate. As the span increases, the cast-in-place concrete layer is often filled with expanded polystyrene boards; the expanded polystyrene boards are laid on the prefabricated thin plates to form a cross-section to reduce the weight of the cast-in-place concrete and can serve as the thermal insulation and sound insulation layer of the composite floor. Since negative steel bars are arranged in the cast-in-place concrete layer, some inter-peak fulcrums are formed, making the box-shaped section a continuous structure. In the cast-in-place layer, steel bars are installed and various equipment pipelines are laid according to the requirements of joint structure and fire protection.
[0006] In the past, the reinforcement molds for the traditional composite slab strips were disposable and could not be dismantled for recycling. After pouring, workers were required to cut off the bottom of the screw, and the molds had to be remade for the next use. Utility Model Content

[0025] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.
[0026] A fixed mold is added to the plate strip of a composite plate, including a first threaded steel bar 1, two second threaded steel bars 2, four galvanized round steels 3 and a long screw 4; all materials are connected into a whole by welding, and when in use, it is necessary to ensure that all materials are firmly fixed to the composite plate and the aluminum template 8.
[0027] Among them: two second threaded steel bars 2 are respectively welded to the bottom of both ends of a first threaded steel bar 1, and the first threaded steel bar 1 and the two second threaded steel bars 2 form an I-shape as a whole; four galvanized round steel bars 3 are respectively welded to the bottom of both ends of the two second threaded steel bars 2, and the two galvanized round steel bars 3 and the second threaded steel bar 2 form an N-shape as a whole; a long screw rod 4 is welded to the middle bottom of a first threaded steel bar 1, and the first threaded steel bar 1 and the long screw rod 4 form a T-shape as a whole; the bottom of the long screw rod 4 is configured with a PVC sleeve 5, a mountain clip 6 and a nut 7.
[0028] The material size of the equipment is determined according to the construction size of the on-site composite slab strip and the thickness of the concrete pouring. For example: the first threaded steel bar 1 is 400mm long and 22mm in diameter. The second threaded steel bar 2 is 100mm long and 10mm in diameter. The galvanized round steel 3 is 80mm long and 10mm in diameter; the length of the galvanized round steel 3 is greater than the designed floor thickness minus the 10mm thickness of the composite slab. Use a coating agent to brush the galvanized round steel 3 before installation to facilitate the removal of the galvanized round steel 3. The long screw 4 is 180mm long and 12mm in diameter. The diameter of the PVC sleeve 5 is 16mm.
[0029] Method of using fixed mold at the laminated plate strip:
[0030] When in use, sponge adhesive strips 9 are pasted on the upper sides of both ends of the aluminum template 8, and the aluminum template 8 is adhered to the bottom of the laminated plate strip through the sponge adhesive strips 9.
[0031] Then, four galvanized round steels 3 are placed across the composite plate strip, the PVC sleeve 5 is put on the outside of the long screw 4, and then the bottom of the long screw 4 is inserted into the gap at the composite plate strip, and at the same time, the bottom of the long screw 4 is inserted into the hole reserved in the aluminum template 8.
[0032] Finally, the mountain-shaped clamp 6 and the nut 7 are installed at the bottom of the long screw 4 , the aluminum template 8 is supported by the mountain-shaped clamp 6 , and is locked and fixed by the nut 7 .
[0033] When the workers on site are reinforcing the laminated plate strip, after the first layer of aluminum formwork is assembled and the laminated plate is hoisted in place, a hole is opened in the center of the aluminum formwork at the plate strip. The hole position should avoid the beard ribs of the laminated plate. When opening the hole, pay attention to the hole diameter of 16mm. It is strictly forbidden to be too large or too small, which will cause the PVC pipe to be unable to be inserted or leakage. There is no need to re-open the hole in each layer in the future. The installation position continues the hole position of the first layer of aluminum formwork, and the mold is fixed to both sides of the laminated plate. The screw is inserted into the 16mm PVC pipe and aligned vertically downward with the reserved hole to ensure that the mold is perpendicular to the laminated plate and the aluminum formwork. The bottom is firmly fixed with nuts and mountain-shaped cards, and the nuts are tightened. The surface ash and slag of the mold need to be cleaned during each installation process, and the galvanized round steel needs to be coated with a coating agent each time it is installed. And stick sponge strips at the contact position between the edges of both sides of the plate strip and the aluminum formwork. The sponge strips must be pasted accurately to better prevent leakage at the joints. After multiple field tests, the mold should be arranged 300mm from the wall and 600mm apart, which can effectively improve the strength of the formwork, offset the impact load of the composite plate strip during concrete pouring, and avoid deformation of the formwork. After the concrete pouring is completed, the joint between the plate strip and the composite plate is smooth, without leakage or misalignment, and the implementation effect is good. After the concrete is initially set, the mold can be removed and reused.
[0034] In the past, when the concrete of the traditional composite slab reached the required strength for demoulding, the bottom template of the slab was removed, and the exposed screws were cut after removal. The reinforcement mold was one-time use and could not be removed for recycling, and needed to be remade for the next use. Nowadays, only one worker is needed to complete the construction, and the removed reinforcement mold can be recycled.
[0035] This reinforcement mold is suitable for the reinforcement construction of the main structure aluminum formwork and the composite plate strip. The leg height can be adjusted according to the designed plate thickness (greater than the designed floor thickness minus the composite plate thickness of 1cm). This mold is suitable for the reinforcement of aluminum formwork and composite plate strips with different plate thicknesses.
[0036] The above detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention but merely represents selected embodiments of the present invention.
