Description

Technical Field

[0001] This utility model belongs to the field of building construction equipment technology, specifically relating to a winter grouting heating and insulation device for building construction. Background Technology

[0002] When grouting equipment foundations in low-temperature winter conditions, the hydration reaction of cement-based grouting materials will slow down or even stop due to the low temperature, resulting in slow strength growth and prolonged setting time of the grout, which seriously affects the construction quality and project progress of the equipment foundations.

[0003] To solve or alleviate the above problems, construction workers generally use long-term heated sheds to maintain the construction temperature. However, since this construction method requires the construction of heated sheds, it takes a long time, which affects the overall construction progress and makes it difficult to meet the actual application requirements.

[0004] To minimize the impact on the construction period, an electric heating cable was laid on the grouting template and insulation material was wrapped around the outside of the template to heat the grouting area. However, uneven heating is prone to occur, which affects the construction quality. Utility Model Content

[0034] Please refer to the following: Figures 1 to 4The present invention provides a heating and insulation device for winter grouting in building construction. The device includes a grouting template 10, an insulation board 20, multiple heat-conducting fins 40, and an electric heating tape 50. The insulation board 20 is located on the outside of the grouting template 10, connected to the template, and forms a heating cavity between the insulation board 20 and the template 10. Multiple heat-conducting fins 40 are located inside the heating cavity, spaced apart from the insulation board 20. The electric heating tape 50 passes through and connects to the heat-conducting fins 40.

[0035] It should be noted that the grouting template 10 is made of steel plate, but it can also be made of aluminum alloy or other metal plates with certain strength and thermal conductivity. The electric heating cable 50 is a low-temperature flame-retardant basic type heating cable, model DXW-10-J, and is equipped with a temperature controller (such as a PID controller) to monitor and adjust the output power of the heating cable.

[0036] The beneficial effects of the winter grouting heating and insulation device for building construction provided by this utility model are as follows: Compared with the prior art, the winter grouting heating and insulation device for building construction provided by this utility model has an insulation board 20 set on the outside of the grouting template 10, forming a heating cavity in the middle. Then, heat-conducting fins 40 are set in the heating cavity, and electric heating tape 50 is threaded on the heat-conducting fins 40. The heat-conducting fins 40 increase the heat conduction area, making the heating more uniform. Moreover, the heat-conducting fins 40 and the insulation board 20 are spaced apart to further reduce heat loss and ensure the heating effect.

[0037] like Figure 3 and Figure 4 As shown in the embodiment of the winter grouting heating and insulation device for building construction provided in this utility model, a plurality of heat-conducting fins 40 are arranged in parallel and spaced apart, and the outer side of the grouting template 10 is provided with a slot corresponding to each heat-conducting fin 40, and the heat-conducting fins 40 are inserted into the slot.

[0038] It should be noted that the slot is designed to hold the heat-conducting fins 40. On the one hand, this facilitates the installation of the heat-conducting fins 40, and on the other hand, it effectively increases the contact area between the heat-conducting fins 40 and the grouting template 10, thereby improving the heat conduction efficiency.

[0039] like Figures 2 to 4 As shown in the embodiment of the present invention, the winter grouting heating and insulation device for building construction provided in this utility model also includes a heat-conducting pipe 60, which passes through and is connected to the heat-conducting fins 40. An electric heating tape 50 is installed inside the heat-conducting pipe 60, and the gap between the electric heating tape 50 and the heat-conducting pipe 60 is filled with heat-conducting mortar.

[0040] It should be noted that the heat pipe 60 is a copper pipe, but it can also be an aluminum pipe, iron pipe, or other pipes with certain thermal conductivity.

[0041] Thermal conductive mastic is a paste made mainly from thermal conductive materials and bonding materials, also known as heat transfer paste, thermal conductive gel or thermal conductive mud. It can be mainly divided into two categories: inorganic (such as plasticized sulfur mastic, silicate mastic) and organic (such as epoxy resin, silicone resin base material), with characteristics such as high thermal conductivity (2 - 6 W / m·K), low thermal resistance and resistance to high and low temperatures (-60°C to 200°C). It forms a continuous heat transfer channel by filling the gaps of tracing heating devices or electronic components.

[0042] Filling the gap between the electric tracing heating tape 50 and the heat conduction tube 60 with thermal conductive mastic can effectively ensure the heat conduction efficiency.

[0043] As Figure 2 and Figure 3 As shown in

[0044] Specifically, the distance between adjacent two heat conduction tubes 60 is 20 - 50 cm, the distance between adjacent two heat conduction fins 40 is 5 - 20 cm, each heat conduction tube 60 is a straight tube, which is convenient to be inserted into the heat conduction fins 40 and is clamped, bonded or welded to the heat conduction fins 40. Both ends of the heat conduction tube 60 are open so that the electric tracing heating tape 50 can pass through.

[0045] As Figure 1 and Figure 2 As shown in

[0046] It should be noted that the sub - board 11 can also be in the shape of a flat plate, an arc - shaped plate, etc., which is specifically set according to actual needs. Multiple heat conduction fins 40 are arranged on three sides of the sub - board 11, and the heat conduction tubes 60 on each outer side are independently arranged. The tracing heating tape passes through all the heat conduction tubes 60 on one sub - board 11 in a snake - like shape.

[0047] As Figure 1 and Figure 2 As shown in

[0048] Specifically, the rigid layer 21 is a plate with a certain strength such as a wooden board, a steel plate, or a plastic plate, and the insulation layer 22 can be made of materials with good heat insulation performance such as a foam board, asbestos, or cotton. The thickness of the insulation layer 22 is generally not less than 5 cm to ensure the heat insulation effect. The insulation layer 22 is bonded, clamped, or bolted to the rigid layer 21.

[0049] As Figure 1 and Figure 2 shown, in a specific implementation manner of the winter grouting heating and insulation device for building construction provided by the embodiment of the present invention, there are two insulation boards 20. The horizontal cross-section of the insulation board 20 is in an "L" shape. The two insulation boards 20 are respectively arranged at both ends of the two sub-boards 11 to lock the two sub-boards 11 together.

[0050] It should be noted that the ends of the two sub-boards 11 are both clamped inside the insulation board 20, and then the two sub-boards 11 are clamped together by the two insulation boards 20, reducing the use of bolts and facilitating disassembly and assembly.

[0051] To further improve the overall strength, a connecting flange can also be provided at the connection of the two insulation boards 20. Bolts are provided to pass through the connecting flange, and the two insulation boards 20 are connected together by the bolts.

[0052] As Figure 1 and Figure 2 shown, in a specific implementation manner of the winter grouting heating and insulation device for building construction provided by the embodiment of the present invention, the vertical cross-section of the insulation board 20 is in an "L" shape, and both the upper and lower ends are connected to the grouting template 10, forming a heating cavity between the insulation board 20 and the sub-board 11.

[0053] It should be noted that steps are provided at both the upper and lower ends of the sub-board 11, and both ends of the insulation board 20 are placed on the step surfaces to position the insulation board 20.

[0054] As Figure 3 and Figure 4 shown, in a specific implementation manner of the winter grouting heating and insulation device for building construction provided by the embodiment of the present invention, a reflective film 30 is further included. The reflective film 30 is arranged inside the insulation layer 22 and is adhered to the insulation layer 22 to reflect thermal radiation.

[0055] Specifically, the reflective film 30 is mainly composed of materials such as aluminum foil, polyethylene film, and fiber fabric, and the aluminum foil layer is responsible for reflecting heat.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
