Description

Technical Field

[0001] The present application belongs to the field of building technology, and specifically relates to a comprehensive temperature control system equipment for low-temperature grouting construction of prefabricated columns. Background Art

[0002] At present, when grouting prefabricated columns of assembled integral frame structures at low temperature, a commonly used method is to draw on the post-grouting process of assembled shear wall structures. The top plate and all the holes around it are sealed with quilts to form a windproof and heat-insulating environment as a whole. The internal area is heated by a heater, and the temperature of each prefabricated column grouting point is manually measured.

[0003] Although this method can meet the requirements for grouting temperature during low-temperature construction, it has the following shortcomings: First, the frame structure has a large open surface, which makes it difficult to seal the whole structure and the sealing effect is not good; second, a post-grouting process is required after the top plate is closed, which causes a large displacement disturbance to the prefabricated columns; third, the heating of the large space inside the frame requires the maintenance of multiple high-power heating equipment, which consumes a lot of electricity; fourth, the manual temperature measurement method used in the maintenance stage requires a lot of manpower and time.

[0004] The prior art discloses a prefabricated column winter grouting construction insulation device (application number: 202321218573.2), including an insulation frame, an insulation canvas arranged on the insulation frame, and a temperature control system and a heating system arranged in the insulation frame. The device is systematic, replacing the original fragmented cotton felt and other components. It is more convenient to install and use, and tin foil is pasted inside for insulation, which can effectively save electricity. After use, it can be stored as a whole for easy turnover. However, the integration of this set of devices is not high, and the various functions are relatively independent. Only the structure of the insulation frame is considered, and the other functions have not been able to get rid of the assistance of traditional process methods. In addition, the recycling rate of the equipment is not high, and it cannot be applied to prefabricated columns of various cross-sectional sizes in various projects. The applicability is not wide enough, and it is easy to incur cost waste for only one-time use.

[0005] To this end, we propose a comprehensive temperature control system equipment for low-temperature grouting construction of prefabricated columns to solve the above problems. Summary of the invention

[0006] The present application provides a comprehensive temperature control system equipment for low-temperature grouting construction of prefabricated columns, including: a fixing rod, a pin, an upper sealing cotton felt cover, a fixing buckle, a lower circular insulation cotton felt cover, a support rod, an electric heating belt, an intelligent temperature control module, a temperature measuring wire, an adjustment belt and a prefabricated column, wherein:

[0008] The lower circular thermal insulation cotton felt cover is installed on the inner side of the lower circular thermal insulation cotton felt cover through four groups of support rods, so that the lower circular thermal insulation cotton felt cover is surrounded by a cylinder, the lower circular thermal insulation cotton felt cover is tightened by the adjustment belt, and the fixing buckle is fixedly connected to the upper sealing cotton felt cover and the lower circular thermal insulation cotton felt cover;

[0009] The intelligent temperature control module is connected to a temperature measuring wire, the temperature measuring wire is arranged in the inner space of the lower circular thermal insulation cotton felt cover, and the intelligent temperature control module is fixedly installed on the outer side of the support rod.

[0010] In some specific embodiments, the number of the fixing rods is four groups, and the four groups of fixing rods are connected head to tail to form a rectangular area.

[0012] In some specific embodiments, the rectangular holes are in a plurality of groups.

[0013] In some specific embodiments, the number of the short square holes is several groups.

[0014] Beneficial effect: It provides a comprehensive equipment with independent sealing function and integrated temperature control system. Relying on this equipment system, it can realize the construction without post-grouting.

[0026] like Figure 1 As shown, a reserved brazing edge 6 is arranged on the upper edge of the upper sealing cotton felt cover 5 around the outer surface of the prefabricated column 14. The number of the reserved brazing edges 6 is four groups. The four groups of the reserved brazing edges 6 form a rectangular area. The fixing rod 1 is inserted into the reserved brazing edge 6. The fixing rod 1 includes a rectangular hole 2 and a short square hole 3. The rectangular hole 2 is used for fixing the fixing rod 1. The pin piece 4 is inserted into the short square hole 3 to fix the adjacent fixing rod 1 so that the upper sealing cotton felt cover 5 is fixed to the prefabricated column 14.

[0027] The lower circular thermal insulation felt cover 8 is installed on the inner side of the lower circular thermal insulation felt cover 8 through four groups of support rods 9, so that the lower circular thermal insulation felt cover 8 is surrounded by a cylinder, and the lower circular thermal insulation felt cover 8 is tightened by the adjustment belt 13, and the fixing buckle 7 is fixedly connected to the upper sealing felt cover 5 and the lower circular thermal insulation felt cover 8;

[0028] The intelligent temperature control module 11 is connected to a temperature measuring wire 12 , and the temperature measuring wire 12 is arranged in the inner space of the lower circular thermal insulation cotton felt cover 8 . The intelligent temperature control module 11 is fixedly installed on the outer side of the support rod 9 .

[0029] Provide a comprehensive equipment with independent sealing function and integrated temperature control system. Relying on this equipment system, it can be achieved without post-grouting construction. Each prefabricated column can be used as a temperature control unit, and intelligent equipment can be used to automatically complete important tasks such as insulation, heating, and temperature measurement, thereby improving the quality of low-temperature grouting construction of prefabricated columns and ensuring structural safety. At the same time, it has the advantages of being reusable and applicable to columns of various sizes.

[0030] This set of temperature control integrated equipment has a simple system structure, is easy to operate, and has low cost. After adoption, the same-layer construction can be adopted without closing the overall working surface. Only the grouting part of each prefabricated column is partially closed, so that the temperature control range is narrowed to the key grouting part. At the same time, with the help of the integrated heating and temperature measurement intelligent system, the automatic temperature control function is realized to solve the instability of manual operation, and the required temperature requirements are achieved during the maintenance stage after grouting, solving the temperature control problem in the low-temperature grouting construction of prefabricated columns. At the same time, the scalable design can facilitate transportation, storage and placement, and the adjustable structural system can be applied to a variety of prefabricated column sizes, with high recycling rate.

[0031] In some specific embodiments, the number of the fixing rods 1 is four groups (4 rods), and the four groups (4 rods) of fixing rods 1 are connected head to tail to form a rectangular area.

[0032] In some specific embodiments, the directions of the rectangular holes 2 and the short rectangular holes 3 are both horizontal.

[0033] In some specific embodiments, the number of the rectangular holes 2 is several groups.

[0034] In some specific implementations, the number of the short square holes 3 is several groups.

[0035] The components include a well-shaped fixing rod 1, an upper sealing cotton felt cover 5, a lower circular insulation cotton felt cover 8, a support rod 9, and an intelligent temperature control device 11. After the components of this set of equipment are assembled, they should be set at the bottom of the prefabricated column at a suitable height and the corners should be well sealed.

[0036] The fixing rod is composed of 4 square steel bars with holes, which are thin in front and thick in the back. Each of them can be inserted and connected with the reserved brazing edge on the upper edge of the upper sealing cotton felt cover 5. The rectangular hole on the steel bar can adjust the position of the insertion end to make it more suitable for the size of the prefabricated column; the short square hole can be inserted with a pin to fix the overall structure, and the friction force makes it fit closely to the prefabricated column to play a sealing role and fix the upper sealing cotton felt cover.

[0037] The upper sealing cotton felt cover is surrounded by a rectangular glass wool felt, one side of which is evenly set with 4 equal length reserved brazing edges, and the brazing edges leave enough space for the square steel bars to be inserted. The tic-tac-toe frame composed of 4 fixing rods can flexibly cope with prefabricated columns of various sizes, and after fixing, it can improve the overall sealing of the equipment.

[0038] The lower circular insulation felt cover is surrounded by a rectangular glass wool felt and is fixed to the upper sealing felt cover by snap fasteners. The main function of this part is to surround the bottom space of the prefabricated column and provide a relatively closed environment and suitable maintenance temperature for the grouting sleeve. There are heating equipment, electric heating, and temperature monitoring equipment on the inside of the cover.

[0039] The support rod is composed of multiple retractable support rods, which can provide effective support for the lower circular insulation cotton felt cover to reach and fix it at a suitable height during operation, and can resist crosswind disturbance to a certain extent. When the lower circular insulation cotton felt cover is stored, it can effectively protect the internal equipment from excessive bending and damage, and is convenient for storage and sorting after use.

[0040] The temperature control device consists of a heating device, electric heating, and a temperature monitoring device. After the lower circular insulation cotton felt cover is formed, the electric heating cable is spirally arranged on the inside of the cover, and the temperature monitoring probe is placed in the space inside the cover to monitor the temperature. The temperature information is wirelessly transmitted to the operator's computer by a temperature control module hanging outside, which can remotely obtain the temperature information inside the cover in real time and remotely adjust the heating temperature of the electric heating cable at any time.

[0041] See also Figures 2 to 6 A comprehensive temperature control system equipment for low-temperature grouting construction of prefabricated columns includes a fixing rod 1, an upper sealing cotton felt cover 5, a lower circular insulation cotton felt cover 8, a supporting rod 9, an intelligent temperature control module 11 and its auxiliary components, an electric heating tape 10, and a temperature measuring wire 12.

[0042] Estimate the size of the prefabricated column 14, select 4 fixing rods 1 of suitable length, adjust the opening direction of the rectangular hole 2 and the short square hole 3 to be horizontal, insert the fixing rods 1 into the reserved brazing edge 6 in turn, lift the 4 fixing rods 1, assemble them together with the upper sealing cotton felt cover 5 to surround the prefabricated column 14 and adjust them to a suitable height. Insert the thinner end into the adjacent rectangular hole 2 in turn and adjust the position, insert the pin 4 into the short square hole 3 to tighten the tic-tac-toe fixing rods as shown in the figure. Figure 2 As shown, the upper sealing felt cover 5 is fixed on the prefabricated column 14.

[0043] Estimate the height of the grouting sleeve of the prefabricated column 14, unfold the lower circular insulation felt cover 8 into a rectangle, install the four support rods 9 to the designated position inside the cover and stretch them appropriately. Stand the lower circular insulation felt cover 8 upright, surround it into a cylinder and tighten the adjustment belt 13 appropriately, install the heating device electric heating belt 10 along the spiral on the inner wall, and tighten the adjustment belt 13 to form a closed cylinder after the installation is completed. Figure 4 shown.

[0044] The fixing buckles 7 are buckled in sequence to connect and fix the upper sealing cotton felt cover 5 and the lower circular insulation cotton felt cover 8, and the height is adjusted to ensure that the upper sealing cotton felt cover 5 remains loose, the support rod 7 touches the ground, and the lower edge of the lower circular insulation cotton felt cover 8 is left with a margin piled on the ground. The temperature measuring wire 12 is connected to the intelligent temperature control module 11, and the end temperature measuring head is placed into the space surrounded by the lower circular insulation cotton felt cover 8 through the dedicated hole, and the intelligent temperature control module 11 is installed on the outside of the designated support rod 9.

[0045] Test and monitor whether the temperature, heating and signal transmission functions are operating normally, check whether there are any large gaps in the entire set of equipment, and only operate after confirmation.

[0046] Working principle: The whole device is wrapped with glass wool felt, so that the interior is in a relatively sealed and heat-insulated state, which can effectively reduce convection and heat exchange with the outside world and reduce the speed of internal temperature drop. After the intelligent temperature control module 11 is started, the temperature measuring wire 12 will monitor the temperature change in real time. Once it is lower than the set temperature, the heating device electric heating cable 10 will be automatically started, and the power will be automatically cut off after the internal temperature is heated to the specified temperature.

[0047] This reciprocating operation keeps the internal temperature higher than the external and suitable temperature at all times, thereby increasing the temperature near the sleeve and ensuring the maintenance temperature of the grouting material, thereby improving the quality of the grouting construction.

[0048] After use, the support rod 7 can be retracted to store the lower circular thermal insulation cotton felt cover 8. Figure 6 The style is convenient for transportation and can protect the device from excessive bending to a certain extent.
