Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a method for winter concrete pouring construction of a waffle tube structure electronic cleanroom. Background Technology
[0002] With the rapid development of high-end manufacturing, cleanrooms are playing an increasingly important role in modern industrial buildings. Cleanrooms place extremely high demands on structural stability, air cleanliness, and construction quality. As a key structural component of cleanrooms, the quality of concrete construction of waffle slabs directly affects the performance standards of the clean space.
[0003] The persistently low temperatures in winter pose significant challenges to concrete construction. Controlling the quality and schedule of concrete pouring for waffle slabs in winter is difficult, with a high risk of frost damage and high construction costs. Therefore, there is a need to provide a winter concrete pouring method for waffle-tube structure electronic cleanrooms that can solve the problems of poor concrete pouring quality and delayed construction schedules caused by persistently low temperatures in winter. Summary of the Invention
[0004] The purpose of this invention is to provide a method for concrete pouring in winter for electronic cleanrooms with waffle tube structures, which can solve the problems of poor concrete pouring quality and impact on construction period in the existing technology of electronic cleanrooms under continuous low temperature conditions in winter.
[0005] To achieve the above objectives, the technical solution of the present invention is as follows:
[0006] A method for winter concrete pouring construction of a waffle tube structure electronic cleanroom includes the following steps:
[0007] Step 1: According to the compartmentalized design of the waffle slab concrete pouring in the electronic cleanroom, a heated shed is erected in the concrete construction area so that the heated shed completely covers the compartment being poured.
[0008] Step 2: Install several heating devices on the lower layer of the current casting compartment structure.
[0009] In step 1, the greenhouse includes columns, a closed shed fabric, and heating equipment; several columns are arranged at intervals along the horizontal and vertical directions in the currently poured compartment to form a grid-like support frame; the closed shed fabric is set on the top and around the support frame to form a closed heat-insulating space; several heating equipment are respectively set in several columns.
[0010] In step 1, the tarpaulin used for sealing the shed is made of three-proof fabric.
[0011] In step 1, four disc-lock steel pipes are connected to form a unit frame, and several unit frames are coaxially spliced to form a column. The heating equipment is installed in one of the unit frames.
[0012] In step 1, the spacing between the columns is 6m × 6m.
[0013] In step 1, the height of the greenhouse is 2.0m-2.5m.
[0014] In step 1, the heating equipment is a small oil-filled electric blast furnace with a power of 2kW / unit. The heating equipment is evenly arranged in the compartment at a density of 50-60 units / compartment.
[0015] Heating equipment is also arranged at the bottom and four corners of the structure of the slab in the current casting compartment.
[0016] In step 2, the longitudinal and transverse spacing of the heating equipment in the lower layer of the current casting compartment structure is 10m.
[0017] Each heating device arranged in steps 1 and 2 is independently controlled.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. This invention constructs a heated shed covering the current concrete pouring section, and raises the temperature inside the shed through heating equipment to meet the environmental requirements for concrete pouring and curing. This not only effectively improves the early strength of the concrete in the waffle slab of the electronic cleanroom and avoids the risk of frost damage, but also effectively ensures the construction period, controls construction costs, and improves the working environment.
[0020] 2. Because the invention incorporates heating equipment in the lower layer of the structure, it can further ensure the quality of concrete pouring and curing of the waffle slab in the electronic cleanroom, ensuring that the construction quality of large-volume concrete meets the standards for use in cleanrooms; the heating equipment uses oil heaters, avoiding open flame operations, making it environmentally friendly and safe.
[0021] 3. This invention constructs a heated shed and arranges heating equipment in the lower layer of the structure according to the concrete pouring rhythm of the waffle slab in the electronic cleanroom. Each heating device is independently controlled, which has the advantages of high layout flexibility, modular design, high energy efficiency and stability. Attached Figure Description

[0026] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the winter concrete pouring construction method for a waffle-tube structure electronic cleanroom proposed in this invention. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.
[0027] Please see the appendix Figure 1 and attached Figure 2 A method for winter concrete pouring construction of a waffle tube structure electronic cleanroom includes the following steps:
[0028] Step 1: According to the compartmentalized design of the waffle slab concrete pouring in the electronic cleanroom, a heated shed is erected in the concrete construction area so that the heated shed completely covers the compartment being poured.
[0029] By setting up a heated shed, an effective pouring and curing environment is provided for the waffle slab concrete pouring of the electronic cleanroom under the continuous low temperature conditions in winter. This ensures the normal pouring construction of the electronic cleanroom waffle slab under the continuous low temperature conditions in winter, and avoids the impact of winter shutdown on the construction progress while ensuring the pouring quality.
[0030] In step 1, the greenhouse includes columns 1, a closed shed cloth 2, and heating equipment 3; several columns 1 are arranged at intervals along the horizontal and vertical directions in the currently poured compartment to form a grid-like support frame; the closed shed cloth 2 is set on the top and around the support frame to form a closed heat-insulating space; several heating equipment 3 are respectively set in several columns 1.
[0031] Preferably, the enclosed shed fabric 2 can be made of three-proof fabric, which has good tensile strength and aging resistance, and can effectively resist the intrusion of cold wind, ensuring that the temperature environment inside the warm shed meets the requirements for concrete pouring and curing.
[0032] Preferably, four disc-lock steel pipes are connected to form a unit frame, and several unit frames are coaxially spliced to form the column 1, with the heating equipment 3 installed in one of the unit frames.
[0033] Disc-lock steel pipes are a standard component in this field, and their erection process will not be described in detail here.
[0034] Preferably, the spacing between the columns 1 is 6m × 6m.
[0035] A unified erection module can be formulated based on the actual grid lines and pouring sections of the project, setting up a standard erection unit such as 6m×6m to realize a modular greenhouse design, which is easy to promote and apply to similar project construction. The spacing of the columns 1 can also be adjusted adaptively according to actual needs.
[0036] The height of the heated enclosure is 2.0m-2.5m, which meets the construction and operation space requirements of the waffle slab in the electronic cleanroom while ensuring that the heat from the heating equipment 3 does not rise excessively, thus maintaining a stable temperature on the working surface. The height of the heated enclosure can also be adjusted according to actual needs.
[0037] The heating device 3 is an oil-filled small electric blast furnace with a power of about 2kW / unit. The heating devices 3 are evenly arranged in the compartments at a configuration density of 50-60 units / compartment.
[0038] Oil-filled radiator type small electric blast furnaces heat up quickly, with a rapid heating response and a temperature rise rate of 4-5°C per hour. They are suitable for emergency heating under sudden temperature changes, and are environmentally friendly and safe, avoiding open flame operations. They are especially suitable for cleanrooms with high safety standards for the construction environment. The type and specifications of heating equipment 3 can also be adapted to meet actual heating needs.
[0039] Preferably, heating devices 3 are also arranged at the bottom and four corners of the structure of the slab in the current casting compartment.
[0040] Heating demand can be calculated based on parameters such as outdoor temperature, concrete thickness, and greenhouse height, and the proportion of heating equipment 3 can be determined, thereby creating a more accurate heat load standard map to provide a better construction environment.
[0041] Step 2: Install several heating devices 3 on the lower layer of the current casting compartment structure.
[0042] Preferably, the longitudinal and transverse spacing of the heating equipment 3 in the lower layer of the current casting compartment structure is 10m.
[0043] The heating equipment 3 in the lower layer of the structure is also arranged according to the rhythm of the waffle slab concrete pouring. The heating equipment 3 in step 2 can be the same specification as the heating equipment 3 in step 1, and the spacing of the heating equipment 3 in step 2 can also be adjusted according to actual usage requirements.
[0044] Each heating device 3 arranged in steps 1 and 2 is independently controlled, which facilitates zoned regulation and allows for flexible adjustment of heating power based on local temperature differences, thereby optimizing energy utilization.
[0045] Preferably, an existing intelligent temperature control monitoring platform can be introduced, utilizing existing temperature monitoring and cloud control technologies to further improve the heating efficiency and stability of the heating equipment 3 inside the greenhouse and the lower layer of the structure, ensuring the quality of the waffle slab concrete pouring in the waffle tube structure electronic cleanroom.
[0046] Please see the appendix Figure 1 and attached Figure 2 Example 1: In the construction of the waffle slab concrete pouring of a waffle tube structure electronic cleanroom, a standard 40m×40m compartment unit was used for compartment pouring.
[0047] Step 1: Set up a greenhouse.
[0048] The heated shed was erected according to the rhythm of the waffle slab concrete pouring in sections. The spacing of the columns 1 was 6m×6m, and the range of the columns 1 was 40m×40m, to ensure the orderly progress of construction and the centralized utilization of heat energy.
[0049] Heating equipment 3 is installed in one of the unit frames of each column 1. The longitudinal and transverse spacing of heating equipment 3 is also 6m, and a total of 36 are arranged. Heating equipment 3 is a small oil-filled electric blast furnace with a power of about 2kW / unit.
[0050] Step 2: Install heating equipment 3 in the lower layer of the structure.
[0051] The heated shed was constructed according to the rhythm of the waffle slab concrete pouring in sections. Heating equipment 3 was installed on the lower layer of the structure, with a longitudinal and transverse spacing of 10m, and a total of 16 heating equipment 3 were installed.
[0052] During the concrete pouring process of waffle slabs, under external temperature conditions of 0℃ to -5℃, after the heating equipment 3 is turned on for one hour, the temperature inside the warm shed can be stably increased by 8℃-10℃, which can achieve the expected goal and meet the needs of concrete pouring and curing.
[0053] After the winter waffle slab construction was completed, the concrete appearance was good, and no common winter defects such as cracks and hollows caused by low temperature were found. The compressive strength of the large-volume concrete at 28 days reached more than 105% of the design value, proving that the curing environment was effective. This solved the problem of difficult concrete construction quality control of waffle slab layers in cleanrooms under continuous low temperature conditions in winter, and helped to achieve normal construction under extreme weather conditions of -5℃. There were no work stoppages throughout the winter construction, ensuring that the project progressed on schedule.
[0054] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
