Description

Technical Field

[0001] The utility model relates to the technical field of template system construction, in particular to a template system of irregular lattice beam slabs. Background Art

[0002] At present, in order to save land and reduce investment costs, some new railway projects have designed high and medium voltage substations, traction substations, and step-down substations as single-story multi-story buildings. Multiple power distribution equipment, such as transformers, rectifiers, inverters, high and medium voltage control cabinets, and communication cabinets, will be arranged on the same floor of the substation (station). Different types of equipment have different requirements for floor loads. Therefore, in addition to the main beam, the secondary beams of the lower support beam layer of the floor are arranged according to the actual location of the equipment, resulting in large differences in the floor section and span between the secondary beams, uneven distribution, and the overall irregular grid beam-slab structure at the bottom of the floor.

[0003] Because the beams under the lattice beam slab are crisscrossed, wooden formwork, plywood formwork, plastic formwork or steel-bamboo formwork is often used in the concrete pouring construction of the floor slab, main beam and secondary beam, supplemented by miscellaneous wood boards, wooden beams, wooden slats, etc. to make the side formwork and bottom formwork of the secondary beam, and wooden formwork, steel formwork or steel-wood formwork is used as the bottom formwork of the main beam and floor slab. The above-mentioned parts are assembled and reinforced to form a cast-in-place floor slab formwork system. The design and construction difficulty of this formwork system is directly related to the specifications, dimensions and distribution patterns of the main beams and secondary beams under the floor slab.

[0004] The existing formwork system of the lattice beam slab is made of multi-layer plate formwork supplemented by miscellaneous wood boards, wooden beams, etc., which are manually assembled and reinforced. First, the side formwork and bottom formwork of the secondary beam and main beam at the bottom of the floor slab are made, and then the bottom formwork of the floor slab is made. Because the size of the secondary beam varies and the vertical and horizontal distribution is irregular, it is necessary to cut out templates of various specifications and sizes on site to assemble the side formwork and bottom formwork of the secondary beam. The process is complicated and the construction is difficult. Moreover, the cut templates cannot be reused, resulting in a large amount of plate waste. Therefore, the utility model was born.

[0030] According to some embodiments of the present application, the detailed steps of the design and construction method of the irregular lattice beam and slab formwork system are as follows: Step 1, design of the formwork system of the lattice beam and slab: ① Collect the types, specifications, and physical and mechanical performance parameters of the formwork materials planned to be used at the construction site; ② Understand the cross-sectional dimensions, spacing, elevations and other information of the main beam 800 and secondary beam 900 at the construction site; ③ Understand the foundation type and drainage conditions at the location of the support system on the spot; ④ According to the above conditions and parameters, use the architectural drawings and structural drawings of the lattice beam and slab as the base map to design the formwork system of the lattice beam and slab, and the design elements include: on the plan view, mark the main beam 800, secondary beam 900 number, cross-sectional dimensions, spacing and polystyrene foam block 510 plane dimensions and other information, and consider the thickness of the concrete protective layer outside the beam reinforcement cage; on the cross-sectional view, draw the elevation of each layer, the bottom formwork laying position and direction, the beam cross-sectional dimensions and elevation, the cast-in-place slab thickness, the cross-sectional dimensions of the polystyrene foam block 510 filling area and other information; ⑤ Order or rent polystyrene foam blocks 510 according to the design drawing of the formwork system of the lattice beam and slab.

[0031] Step 2. Design and construction of 400 support system for lattice beam and slab scaffolding: ① Determine the calculation unit for bearing capacity demand verification according to the provisions of the building structure load code: including floor slab, main beam 800, secondary beam 900, formwork system, etc. The floor slab should consider the upper additional layer, such as floor tiles, leveling layer, etc.; ② Design the support system of the lattice beam and slab and verify the bearing capacity demand. The main design elements include floor slab thickness, steel bar diameter, formwork material, contact area between concrete and formwork, formwork height, area of ​​holes on the slab, etc. The area of ​​the side wall formwork for reserved holes in the floor slab is included in the calculation of the formwork engineering quantity; the engineering quantity of the full-floor scaffolding 400 is calculated according to the net area of ​​the indoor floor slab (horizontal projection area). When the height is between 3.6m-5.2m, the basic layer is calculated. When it exceeds 5.2m, each additional 1.2m is calculated as an additional layer (when it exceeds but is less than 0.6m, it is ignored). The floor height is based on the distance from the indoor floor surface to the bottom of the floor; the expression is as follows: the additional layer of the full-floor scaffolding 400 = [indoor net height-5.2] / 1.2 (m); ③ Build the full-floor scaffolding 400 system according to the design plan of the beam and slab scaffolding 400 support system;

[0032] Step 3: Laying the bottom formwork of the lattice beam slab: Use steel formwork, steel-wood formwork 700 or other material formwork to lay the entire layer of bottom formwork. The elevation of the upper surface of the bottom formwork should be consistent with the elevation of the concrete surface at the bottom of the beam;

[0033] Step 4: Positioning and setting out the main beam 800 and secondary beam 900 and making the steel cage: ① According to the center line of the vertical and horizontal axis of the civil engineering, position and set out the main elements of the floor slab such as the main beam 800, secondary beam 900, and various reserved holes on the bottom template of the whole floor; ② Make the steel cage of the main beam 800 and secondary beam 900, and evenly place the steel protection layer pads; ③ Check the quality of the steel cage production and make adjustments;

[0034] Step 5: Making and fixing the triangular positioning wooden slats 520: ① Making triangular positioning wooden slats 520 with a cross-sectional height of 3 cm; ② Checking the positions of the main beam 800, the secondary beam 900, the reserved holes, and the formwork system according to the center lines of the longitudinal and transverse axes of the civil engineering and the formwork system design drawings; ③ Fixing the triangular positioning wooden slats 520 on the bottom formwork of the lattice beam slab to prepare for placing and positioning the polystyrene foam blocks 510;

[0035] Step 6, cutting and positioning of polystyrene foam blocks 510: ① Accurately cut the length, width and height of each polystyrene foam block 510 according to the beam-slab cross-section between the main beam 800 and the secondary beam 900, the beam body height, and the spatial position of the beam reinforcement cage; ② Wrap the polystyrene foam block 510 with a plastic gel coat to complete the surface treatment; ③ Place the polystyrene foam block 510 at the corresponding position of the lattice beam and clamp it between the triangular positioning wooden slats 520; the triangular positioning wooden slats 520 can ensure that the polystyrene foam block 510 does not shift when the beam-slab concrete is poured;

[0036] Step 7: Concrete pouring and curing of beam and slab: ① Use steel formwork, steel-wood formwork 700 or other material formwork to set up the reserved hole formwork of the floor slab; ② Lay and fix the steel wire mesh of the concrete slab; ③ According to the quality control standards for beam and slab concrete construction, concrete raw materials and performance requirements, pour the beam and slab concrete according to the construction plan, and perform curing according to the construction quality specifications;

[0037] Step 8. Dismantling of beam and slab concrete formwork system: ① After the performance of beam and slab concrete reaches the design requirements, dismantle the beam bottom formwork and scaffolding 400 system. The dismantling process follows the general procedure: dismantle the later supports first, and the earlier supports last; dismantle the non-load-bearing parts first, and then the load-bearing parts, and do not damage the components or formwork; ② Remove the polystyrene foam blocks 510 to complete the beam and slab construction.
