Description

Technical Field

[0001] The invention belongs to the technical field of waffle board construction, and in particular relates to a construction method of a waffle board with a detachable whole tube. Background Art

[0002] With the rapid development of information technology, the construction of electronic factories such as panel factories and IC factories has reached a peak in recent years. Among them, IC (chip / semiconductor industry) factories are more complicated to design and construct than ordinary processing factories, and the construction quality requirements are higher. The main feature of chip factories compared to ordinary factories is the clean room structure. In order to ensure the air cleanliness of large-scale production workshops, it is necessary to establish a clean air conditioning and ventilation system. It is usually required to evenly reserve a large number of holes in the workshop floor to form a return air channel, and waffle board floors are usually used.

[0003] Traditional waffle cones are made of materials such as SMC (glass fiber reinforced plastic) and FRP resin, which serve as both a formwork and a part of the engineering entity. Since the waffle cone itself is a part of the engineering entity, that is, the formwork cannot be turned over, the overall economic effect is not good. During the construction process, the beam height is high and the construction space is small, which makes it difficult to tie the bottom steel bars, further affecting the construction progress and quality. In addition, the durability of the formwork is limited, and it is difficult to reuse after use, which increases the project cost. In addition, the durability of the formwork is limited, and it is difficult to reuse after use, which increases the project cost. Summary of the invention

[0004] In view of this, the present invention proposes a waffle board construction method with a completely detachable tube, which can solve the problem that during the construction of the waffle board, the high beam height and the narrow construction space make it difficult to tie the bottom steel bars, which is unfavorable to the construction progress and construction quality.

[0005] The present invention is achieved in that:

[0006] The present invention provides a method for constructing a waffle plate with a detachable whole tube, which comprises the following specific steps:

[0007] S10: According to the construction drawings, formwork is matched at the construction location of the waffle board, and poles are erected at the construction location to lay out the lines, set up full-floor scaffolding, measure the mark, and install the formwork;

[0008] S20: Clean the building formwork board surface, place the waffle formwork reference line and ink line;

[0009] S30: Lay out the waffle cone base according to the reference line;

[0010] S40: Tie the waffle plate reinforcement, install the cylinder body and cylinder cover, press the top wood square firmly, and tie the ends of the wood square with the waffle plate reinforcement;

[0011] S50: pour the first half of the waffle slab concrete, remove the top wood when it is half dry, and continue pouring the waffle slab concrete;

[0012] S60: After finishing the surface layer, remove the formwork, fully spread the formwork, protect the surface layer, lay 15mm thick flat steel plate and then set up the upper frame to complete the construction of the detachable waffle plate of the whole tube.

[0013] The technical effects of the whole-tube detachable waffle board construction method provided by the present invention are as follows:

[0014] (1) Through precise formwork support and laying, the binding of the bottom steel bars is facilitated, errors and deviations in the construction process are avoided, the degree of standardization is high, the construction accuracy is high, the finished product effect is ideal, quality defects are reduced, and the cost of later repairs is avoided, which greatly saves quality costs. On-site assembly only requires the assembly of standardized units, thereby improving work efficiency. Each formwork can be assembled separately, so a large number of installers can be organized to install at the same time, thereby shortening the construction period.

[0015] (2) A series of measures were taken to avoid damage and deformation during construction and extend the service life of the formwork. In addition, the smoothness and strength of the concrete surface were ensured and the overall performance of the floor slab was improved by carefully designing and implementing the concrete pouring and curing plan.

[0016] (3) Through precise layout and installation, effective anti-leakage measures, protection of waffle board formwork, and scientific concrete pouring and maintenance plans, high-quality floor construction is achieved, which has broad application prospects and promotion value.

[0017] On the basis of the above technical solution, the construction method of a waffle plate with a whole tube that can be detached of the present invention can also be improved as follows:

[0018] The specific steps of setting up poles and laying out lines, erecting full-floor scaffolding, measuring marks, and installing templates at the construction location include:

[0019] The first step is to use the laying-out device to pop out the beam axis, beam position line and beam-slab horizontal line at the construction location, and then check and erect a full-height steel pipe rack on the floor;

[0020] The second step is to start the installation from one side of the side span, install the first row of keels first, temporarily fix them, and then install the second row of keels, one row at a time;

[0021] The third step is to install the top support assembly at the bottom of the keel, adjust the top support height, and level the main keel. When the span of the beam bottom plate is equal to or greater than 4m, the beam bottom support arches, and the arch height is 1‰-3‰ of the beam span;

[0022] The third step is to lay the beam bottom formwork first, then the beam side formwork and the slab bottom formwork;

[0023] Step 4: After the platform slab is laid, use a level to measure the template elevation, make corrections, and use a ruler to level it. Clean up the debris on the template and conduct a pre-inspection.

[0024] The fifth step is to install the template at the intersection of the main and secondary beams. At the intersection of the main beam with a column and the bottom of the secondary beam, first support the column head template, then support the bottom template and side template of the main and secondary beams. At the intersection of the secondary beams, first support the bottom template of the beam, leave a beam gap on the higher side template of the secondary beam, and support the side template of the secondary beam at the same time. Paste sponge strips at the intersection to ensure the tightness of the template support and prevent leakage;

[0025] Step 6. The formwork must be laid to ensure full-length joints and the seams between the plates must be treated with glue to prevent leakage when pouring concrete.

[0026] Furthermore, the specific structure of the jacking assembly includes a hanging ear, a horizontal determination assembly, a top plate, a support frame, a slide rail, a pushing assembly and a horizontal adjustment assembly, the hanging ear is arranged on the ceiling of the construction position, one end of the horizontal determination assembly is fixedly connected to the hanging ear, and its height from the ground is the same as the height of the side wall of the top plate from the ground; one side of the horizontal determination assembly is connected to the side of the top plate away from the horizontal determination assembly; the top plate is arranged at the bottom of the keel, for supporting the keel and ensuring the horizontality of the position when the keel is installed; the support frame is arranged at the bottom of the top plate, and the support frame is raised and lowered by the height of the top plate; the horizontal adjustment assembly is arranged at the position where the top plate is connected to the support frame, and the horizontal adjustment assembly is used to adjust the horizontality of the top plate; the slide rail is arranged on the side wall of the support frame, the two sides of the pushing assembly are engaged in the inside of the slide rail, and move up and down along the slide rail, for pushing the top plate to adjust its shape to support keels of different shapes.

[0027] The beneficial effects of adopting the above-mentioned improvement scheme are:

[0028] (1) The height of the jacking assembly can be adjusted as needed to ensure that the keel is in an ideal horizontal position when installed. This adjustment function is particularly important when the span of the beam bottom plate is large (such as 4 meters and above), because the beam will deform or tilt to a certain extent under such a span. The adjustment of the jacking assembly can accurately adjust the height of the beam bottom, thereby ensuring that the keel is accurately aligned on the horizontal plane.

[0029] (2) The flatness of the keel is crucial to the stability of the entire structure. Especially when the beam span is large, the bottom of the beam is prone to slight arching, that is, the beam bottom plate is unevenly stressed and slightly arched. The jacking assembly can help correct this arching phenomenon by adjusting the height of the support point, adjust the keel to a horizontal state, ensure the flatness of the beam bottom, and avoid damage caused by uneven stress on the structure.

[0030] (3) For beam bottom plate spans greater than or equal to 4 meters, the bottom of the beam needs to be arched to a certain extent according to the specification requirements. Arching refers to a slight curvature of the bottom plate of the beam, which helps to maintain the overall stability and uniform force of the beam under structural loads. The jacking assembly can accurately adjust the height of the arch, usually between 1‰ and 3‰ of the beam span. This means that the jacking assembly not only helps to level the keel, but also adjusts the slight arch of the bottom of the beam according to specific needs to ensure that the force of the beam meets the design requirements.

[0031] (4) During the construction process, the use of the jacking assembly makes the adjustment of the keel more convenient and accurate. Through the jacking assembly, construction workers can quickly adjust the height of the keel, avoiding tedious repeated measurements and adjustments, greatly improving construction efficiency. In addition, the structural design of the jacking assembly can usually withstand a large load, ensuring that the keel remains stable during construction and is not prone to tilting or deformation.

[0032] (5) Through the precise adjustment of the top support components, the keel can maintain better levelness and stability, which is crucial to the safety of the entire structure. Especially in the case of large-span beam bottom support arching, precise adjustment and appropriate arch height can effectively distribute and transfer loads and avoid structural problems caused by uneven or unstable keels.

[0033] Furthermore, the horizontal determination component includes a suspension tube, a shock absorbing component, a hoisting component, a pressure sensing component, a positioning line and a Hall angle sensor, the suspension tube is fixed to the suspension ear through the hoisting component, and the shock absorbing component is arranged at the bottom of the suspension tube, and the shock absorbing component is used to prevent the suspension tube from shaking; the opening direction of the suspension tube is toward the direction of the top plate, and the pressure sensing component is arranged at the middle position of the inner ring and the edge position of the opening, and a connecting plate is arranged at the inner center position of the suspension tube, one end of the connecting plate is fixedly connected to the bottom center of the suspension tube, and the other end is connected to the positioning line, one end and the other end of the positioning line are fixed to the edge position of one side of the top plate away from the horizontal determination component, and the horizontality of the top plate is detected by detecting the position of the positioning line by the pressure sensing component;

[0034] The connection plate is provided with the Hall angle sensor, and the Hall angle sensor is used to measure the deflection angle of the connection plate;

[0035] The side of the top plate close to the suspension tube is flush with the center point of the opening position of the suspension tube, and the suspension tube is cylindrical in shape, and the cross-sectional diameter of the side close to the top plate is larger than the cross-sectional diameter of the side away from the top plate.

[0036] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the level determination component determines the levelness of the keel by the principle of gravity. The level determination component can quickly and accurately provide a reference line or plane to help construction personnel make timely corrections during the installation process; it can greatly improve construction efficiency and reduce the time for manual inspection and adjustment, thereby speeding up the construction progress. Maintaining the levelness of the keel is crucial to the structural stability of the entire ceiling. If the keel is not kept level during the installation process, it will lead to uneven ceilings, loose ceilings, and even deformation or sagging in later use. The level determination component helps to ensure the overall stability of the keel system and the ceiling system through precise level adjustment, avoiding these problems.

[0037] Furthermore, the three hanging ears form an equilateral triangle structure on the ceiling of the construction location, and are connected to the hanging assembly via three hanging ropes. A threading hole is provided on the top of the hanging assembly for positioning the three hanging ropes. A regular tripod is connected to the middle position of the regular triangular pyramid formed by the three hanging ropes, and weight blocks are connected to the three corners of the regular tripod. The weight blocks are used to ensure that the three corners of the regular tripod are evenly stressed and always face the vertical direction to ensure the horizontality of the regular tripod.

[0038] The beneficial effect of adopting the above-mentioned improvement scheme is that when the three wires are evenly distributed on the lifting assembly, the generation of asymmetric torque can be effectively avoided.

[0039] Further, the pressure sensing component includes a pressure sensor and a convex member, and the convex member is arranged at the bottom of the pressure sensor;

[0040] Each group of the pressure sensing components includes 4 to 8 components, and the arcs of the intervals between adjacent pressure sensing components in each group are the same and are located on the same cross section of the suspension tube;

[0041] The positioning line is formed by a plurality of spiral steel wires, and the diameter of the positioning line is the same as 2 / 3 of the minimum cross-sectional radius of the suspension tube.

[0042] Furthermore, the top plate includes a top layer, a middle layer and a bottom layer. The top layer, the suspension tube and the bottom layer are fixedly connected in sequence by bolts, and the elastic coefficient decreases from top to bottom, so that the force on the top plate is more uniform.

[0043] The beneficial effects of adopting the above improvement scheme are as follows: the design with the elastic coefficient decreasing from top to bottom can effectively disperse the force on the top plate, reduce the stress concentration on the upper layer, and enhance the overall stability and seismic performance of the structure. The higher elastic coefficient helps the upper layer to bear more load, while the lower layer can provide better support and buffering, ultimately improving the deformation resistance of the entire system.

[0044] Furthermore, the middle position of the top plate is set as a pleated structure for matching with the top shape of the pushing component to arch the bottom plate of the beam.

[0045] Furthermore, the horizontal adjustment component includes three support feet with adjustable heights, each of which is composed of a threaded rod, a nut and a top seat connecting plate. The support feet adjust the horizontality of the top seat by rotating the nut to ensure that the horizontal adjustment assembly compensates for the instability of the top plate; a fine-tuning layer is provided on the top of the top seat, and the fine-tuning layer is driven by a piezoelectric ceramic stack. The expansion and contraction of the piezoelectric ceramics are controlled by applying different voltages, so as to fine-tune the height of the top plate.

[0046] The beneficial effect of adopting the above-mentioned improvement scheme is that the height of the support feet can be gradually adjusted by rotating the nut to ensure the horizontal state of the top seat. This mechanical method enables the top plate to better adapt to uneven ground or inclination caused by structural deformation, ensuring that it remains horizontal during installation or use. By combining the nut rotation adjustment and the dynamic adjustment method of the piezoelectric ceramic fine-tuning layer, the horizontal adjustment component has good adaptability. The nut adjustment provides a larger and rougher adjustment space, which can be quickly positioned during installation or preliminary adjustment. The piezoelectric ceramic layer provides more subtle dynamic adjustment, which can respond to and correct minor unevenness or instability of the top plate in real time. This dual adjustment mechanism enables the system to adapt to complex or dynamically changing environmental requirements.

[0047] Furthermore, a pushing member is provided on the top of the pushing assembly, and the shape of the pushing member is the same as the shape of the keel to be fixed.

[0048] Compared with the prior art, the construction method of the whole-tube detachable waffle board provided by the present invention has the following beneficial effects:

[0049] (1) Through precise formwork support and laying, the binding of the bottom steel bars is facilitated, errors and deviations in the construction process are avoided, the degree of standardization is high, the construction accuracy is high, the finished product effect is ideal, quality defects are reduced, and the cost of later repairs is avoided, which greatly saves quality costs. On-site assembly only requires the assembly of standardized units, thereby improving work efficiency. Each formwork can be assembled separately, so a large number of installers can be organized to install at the same time, thereby shortening the construction period.

[0050] (2) A series of measures were taken to avoid damage and deformation during construction and extend the service life of the formwork. In addition, the smoothness and strength of the concrete surface were ensured and the overall performance of the floor slab was improved by carefully designing and implementing the concrete pouring and curing plan.

[0051] (3) Through precise layout and installation, effective anti-leakage measures, protection of waffle board formwork, and scientific concrete pouring and maintenance plans, high-quality floor construction is achieved, which has broad application prospects and promotion value.

[0060] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0061] like Figure 1 FIG. 1 is a flow chart of a method for constructing a waffle plate with a detachable whole tube provided by the present invention. The process includes the following specific steps:

[0062] S10: According to the construction drawings, formwork is matched at the construction location of the waffle board, and poles are erected at the construction location to lay out the lines, set up full-floor scaffolding, measure the mark, and install the formwork;

[0063] S20: Clean the building formwork board surface, place the waffle formwork reference line and ink line;

[0064] S30: Lay out the waffle cone base according to the reference line;

[0065] S40: Tie the waffle plate reinforcement, install the cylinder body and cylinder cover, press the top wood square firmly, and tie the ends of the wood square with the waffle plate reinforcement;

[0066] S50: pour the first half of the waffle slab concrete, remove the top wood when it is half dry, and continue pouring the waffle slab concrete;

[0067] S60: After finishing the surface layer, remove the formwork, fully spread the formwork, protect the surface layer, lay 15mm thick flat steel plate and then set up the upper frame to complete the construction of the detachable waffle plate of the whole tube.

[0068] Among them, in the above technical scheme, the specific steps of setting up poles and laying out lines at the construction location, setting up full-floor scaffolding, measuring marks, and installing templates include:

[0069] The first step is to use the laying-out device to pop out the beam axis, beam position line and beam-slab horizontal line at the construction location, and then check and erect a full-height steel pipe rack on the floor;

[0070] The second step is to start the installation from one side of the side span, install the first row of keels first, temporarily fix them, and then install the second row of keels, one row at a time;

[0071] The third step is to install the top support assembly at the bottom of the keel, adjust the top support height, and level the main keel. When the span of the beam bottom plate is equal to or greater than 4m, the beam bottom support arches, and the arch height is 1‰-3‰ of the beam span;

[0072] The third step is to lay the beam bottom formwork first, then the beam side formwork and the slab bottom formwork;

[0073] Step 4: After the platform slab is laid, use a level to measure the template elevation, make corrections, and use a ruler to level it. Clean up the debris on the template and conduct a pre-inspection.

[0074] The fifth step is to install the template at the intersection of the main and secondary beams. At the intersection of the main beam with a column and the bottom of the secondary beam, first support the column head template, then support the bottom template and side template of the main and secondary beams. At the intersection of the secondary beams, first support the bottom template of the beam, leave a beam gap on the higher side template of the secondary beam, and support the side template of the secondary beam at the same time. Paste sponge strips at the intersection to ensure the tightness of the template support and prevent leakage;

[0075] Step 6. The formwork must be laid to ensure full-length joints and the seams between the plates must be treated with glue to prevent leakage when pouring concrete.

[0076] The error of the waffle template baseline should be less than 2mm.

[0077] The specific method to press the top wooden planks firmly is: press the top wooden planks without leaving any gaps, and fix the wooden planks and steel bars firmly to prevent the cylinder from floating up.

[0078] The specific method of tying and fixing the ends of the wooden squares and the steel bars of the waffle plate is as follows:

[0079] The first step is to consider the placement and binding of the waist reinforcement of the main and secondary beams during the steel bar binding construction. When binding the main beam reinforcement, the longitudinal and transverse waist reinforcement can be pre-bound to the bottom of the upper main reinforcement of the main beam (a binding point is set every 2m). After the main reinforcement of the main beam is tied in place, the waist reinforcement and the surface layer main reinforcement binding points are twisted off, and the waist reinforcement is tied in place according to the requirements of the design drawings;

[0080] The second step is to protect the waffle board formwork when tying the steel bars, using wooden formwork and square timber as cushions;

[0081] The third step is to conduct technical briefings on steel bar tying for the construction team before the steel bar tying construction, and strengthen on-site supervision and technical guidance during the steel bar tying construction to ensure that the steel bar tying work is completed correctly and smoothly;

[0082] The fourth step is to strictly control the reinforcement protection layer according to the design requirements. The reinforcement protection layer adopts mortar pads of the same grade, and the spacing between the pads is designed to be no more than 1000mm in both directions.

[0083] The specific method of pouring the first half of the waffle slab concrete, removing the top wood when it is half dry, and continuing to pour the waffle slab concrete is:

[0084] The first step is to lay a 2m wide plywood walkway above the waffle board formwork during the horizontal transportation of materials. Material transporters are not allowed to step directly on the pipe caps, and other construction workers should try to avoid stepping on the pipe caps to cause damage or deformation of the waffle board formwork;

[0085] The second step is that during the laying process of the waffle board template, the waffle board template must not be dragged on the fully laid plywood to avoid scratches on the surface of the waffle board;

[0086] The third step is to pour concrete at 2 / 3 of the floor thickness according to the different thickness of the waffle slab. The concrete is poured in two times. After the first layer is poured, the wood is removed to prevent the concrete from being poured to the designed elevation at one time.

[0087] The fourth step is to pour concrete by pumping combined with concrete placing machine according to the actual situation on site, and to finish the concrete. During the pouring, the discharge hose cannot touch the waffle tube body. The template or other protective materials should be laid under the pipe cap and steel pipe rack of the waffle template to avoid damage to the surface of the waffle template.

[0088] Step 5. When pouring concrete, you cannot pour directly on the waffle board formwork. You need to add a chute or baffle to discharge the concrete to prevent the waffle formwork from being dislocated and deformed, and take protective measures on the surface of the waffle board concrete.

[0089] The sixth step is to vibrate the concrete using a vibrating rod. Try to avoid the vibrating rod from contacting the steel bars and formwork. Pay special attention to the fact that the vibrating rod cannot touch the cover plate and the bottom. During the construction, the vibrator should be given special instructions.

[0090] After finishing the surface layer, the formwork is removed, the formwork is fully laid, the surface layer is protected, and the upper frame is set up after laying a 15mm thick flat steel plate. The specific method for completing the construction of the whole tube detachable waffle board is as follows:

[0091] The first step is to manually finish the surface while pouring concrete. Fix the molds on both sides of the concrete pouring area, finish the surface in the middle with a scraper, and process the concrete at the edge of the cover plate. When the concrete is initially set, use a grinder to compact and level it. When the concrete is close to final setting (no sinking when stepped on), use a grinder to level and polish it.

[0092] The second step is to sprinkle water on the concrete surface and cover it with plastic film for curing within 24 hours after concrete pouring. The curing period is 14 days. If the curing water is insufficient, spray an appropriate amount of water under the film.

[0093] The third step is that since the waffle slab floor has a large number of reserved holes and the flatness of the concrete surface is extremely high, the third layer of waffle slab must be covered with formwork for protection before the fourth layer is constructed after the third layer is poured to prevent the fourth layer from damaging the third layer.

[0094] The specific steps for processing the concrete at the edge of the cover slab are:

[0095] The first step is to ensure that the concrete surface around the cover plate and the top cover surface are highly flat during the paving and leveling process. Professional finishing workers should focus on finely leveling and finishing the perimeter of each cover plate;

[0096] The second step is to use an iron trowel to smooth and finish the details around the top cover of the formwork, and press from the concrete surface to the top cover. Wipe the top cover with cotton yarn at any time to ensure that there is no concrete aggregate on the top cover surface. The slurry thickness cannot exceed 1mm, so as to ensure the smooth finishing effect;

[0097] The third step is to use a polishing machine to compact and level the slurry during the initial setting. A dedicated person should also follow up to deal with the excessively thick slurry and concrete aggregate on each top cover surface;

[0098] Step 4: Before final setting, the grinder should clean the concrete top cover surface and use the sharpened steel bar head to cut and remove the floating slurry on the top cover along the positioning ring with a diameter of 350mm;

[0099] The fifth step is to remove the top cover within 24 hours after pouring the concrete. After the formwork is removed, there will be a few uneven edges with burrs. After removing the burrs, use sandpaper to polish them. If the edges exceed 3mm, use cement slurry with glue to fill them, and then polish them with sandpaper.

[0100] like Figure 2-5 As shown in the above technical solution, the specific structure of the jacking assembly includes a hanging ear 10, a horizontal determination assembly 20, a top plate 30, a support frame 40, a slide rail 50, a pushing assembly 60 and a horizontal adjustment assembly 70.

[0101] Furthermore, in the above technical scheme, the horizontal determination component 20 includes a suspension tube 21, a shock absorbing component 22, a hoisting component 23, a pressure sensing component 24, a positioning line 25 and a Hall angle sensor 26.

[0102] A Hall angle sensor 26 is provided on the connecting plate, and the Hall angle sensor 26 is used to measure the deflection angle of the connecting plate;

[0104] Furthermore, in the above technical solution, the three hanging ears 10 form an equilateral triangle structure on the ceiling of the construction location, which is connected to the hanging assembly 23 through three hanging ropes.

The pressure sensing component 24 is electrically connected to the CPU and the display to display the pressure data in real time. The nuts of each leg of the level adjustment component 70 are adjusted respectively to adjust the height of the connecting plate so that the top plate 30 is level.

[0113] Specifically, the principle of the present invention is: by accurately controlling the support and laying of the formwork, the installation accuracy and stability of the waffle board formwork are ensured, thereby improving the construction quality and efficiency of the floor slab.
