Description

[Technical Field]

[0001] This invention relates to a heat-shielding sheet for temporary construction site offices used at construction sites, etc. It relates to a heat-shielding structure for tents, and enables efficient cooling in the summer in temporary construction site offices such as construction sites. [Background technology] [Background technology]

[0002] Traditionally, temporary construction site offices are tentative, so they are designed to withstand strong winds and other elements, and are made of sturdy steel so that they can be set up simply by setting them up. As a result, the interior is made of steel, which has a high thermal conductivity, so on sunny days and in the summer, the indoor temperature can exceed 40°C, creating an extremely hot space. Air conditioning is installed, but it cannot withstand the heat of the sunlight, and the reality is that it is not a comfortable space. For this reason, at construction sites where large tracts of land are being cleared, it is common to see one large tree left standing so that workers can cool off in its shade, and then the tree is removed at the end of the construction work.

[0003] This has become an urgent issue in order to prevent heatstroke in recent times. A heat-shielding measure for temporary construction site offices has been proposed in Patent Publication No. 2014-114987 (Patent Document 1). This method proposes a temporary air conditioning unit that can be easily installed locally without air conditioning construction work, while achieving compactness and low cost.

[0004] This method has also been proposed as an invention in Patent Publication No. 2017-150170 (Patent Document 2). This method aims to improve the thermal insulation of the roof and side walls of outdoor installations such as containers and temporary houses, thereby suppressing the rise in internal temperature, particularly in the summer. The roof and side walls of the container are constructed from insulating boards in which a galvalume steel plate is attached integrally to one side of a hollow structural plate having a hollow interior, and a heat-shielding paint is applied to the surface of the galvalume steel plate. While this provides a heat-shielding effect, it requires galvalume steel plate and paint, making it expensive due to the cost of materials and construction.

[0005] One of the most effective conventional solutions to the above problems is a seven-layer heat-shielding sheet, which consists of a tent base fabric made of polyethylene fiber material and a metal coating layer made of aluminum with an infrared emissivity of 0.1 to 0.5. According to an internet website, this heat-shielding material has a seven-layer structure of aluminum foil, polyethylene, bubble polyethylene, polyethylene, bubble polyethylene, polyethylene, and aluminum foil (product name: THB-X, manufactured by Japan Heat Shield Co., Ltd.).

[0006] This invention solves the above problems while reducing construction costs and time, and also makes it possible to reuse the heat-shielding sheet. This structure uses a heat-shielding sheet that solves all of these problems at once, and provides a heat-shielding sheet for a temporary construction site office that is inexpensive and easy to use.

[0008] [Patent Document 1] Patent Publication No. 2014-114987 [Patent Document 2] Patent Publication No. 2017-150170 Summary of the Invention [Problem to be solved by the invention]

[0009] The magnetic strips can be attached to the entire length of the sheet or to several locations as needed, depending on the situation. The interior walls of the temporary construction site office are 240cm high, so it is desirable that the heat-shielding sheet be 100cm wide and 240cm long.

[0010] Of course, the size of the windows and doors should be adjusted as needed. The heat shielding sheet for the temporary construction site office can be completed simply by attaching the heat shielding sheet with magnetic tape to the inner wall using magnetic force. As a result, actual measurements showed that the indoor temperature was kept at 25°C by the air conditioner.The tent frame was fitted with a known heat-shielding sheet attached to the ceiling and side walls.The air conditioner was able to keep the indoor temperature at 25°C.Furthermore, significant energy savings can be expected.

[0011] The heat shield sheet is made of aluminum and polyethylene, has an infrared emissivity in the range of 0.1 to 0.5, and is a heat shield sheet on which a metal coating layer made of aluminum is laminated.

[0012] By utilizing the above, we have been able to provide a heat-shielding structure for a temporary office at a construction site at low cost, which is easy to set up and dismantle and is expected to have a heat-shielding effect.

[0013] [Means for solving the problem]

[0014] The heat shield sheet for the temporary construction site office tent of this invention uses a conventional heat shield sheet and has magnetic tape attached to at least the top and bottom edges of the roof and side walls of the temporary construction site office, and is made in sections to fit the ceiling and side walls made of steel plate. Installation can be done very efficiently.

[0015] When implementing the above, it is important to ensure the strength of the heat-shielding sheet, as it will be attached directly to the tent frame. It is therefore important that the thickness of the sheet be determined taking strength into consideration, with a thickness of 0.3mm to 1.0mm being desirable. [Effects of the Invention]

[0016] The heat-shielding sheet for temporary construction site offices of this invention maximizes the heat-shielding effect, is inexpensive, and is easy to install and remove. [Brief explanation of the drawings]

[0017] [Figure 1] This is a back view showing the heat-shielding structure of the tent of this invention, with magnetic tape attached to two places on the top and bottom ends. [Figure 2] This is a rear view of the same figure in which magnetic tape has been attached to the left and right ends of the vertical side. DETAILED DESCRIPTION OF THE INVENTION

[0018] To explain an embodiment of the present invention, the heat shield sheet A for the temporary construction site office shown in Figure 1 is 100 cm wide and 240 cm long, and magnetic tape 2 is attached to the top and bottom ends of the sheet 1. Figure 2 shows the same product as Figure 1, with magnetic tape 2 of the required length attached to the left and right ends. The magnetic tape 2 on the left and right sides of the sheet 1 may be attached to the entire length of the long vertical width, but considering ease of removal, it is better to attach it to a length of about one-quarter to one-third of the entire length.

[0019] In the above embodiment, where the ceiling and side wall sections meet, an overlap of 2 cm to 5 cm may be provided as necessary to prevent heat from the outside air from entering and cold air from the air conditioner from escaping.

[0020] Furthermore, compared to conventional designs that only considered heat insulation, it can be installed in a short time while still maintaining heat insulation effects, and it is expected that it will be able to be used comfortably at construction sites and event venues. It can also be easily removed once construction or an event is over. [Industrial Applicability]

[0021] This invention has great industrial value because it can be installed and dismantled easily and inexpensively, and it can provide a comfortable rest space without the worry of heatstroke. [Explanation of symbols]
