Technical Field
[0001] The utility model relates to the technical field of foundation pit support construction, in particular to a thermal insulation shed for winter construction of shotcrete between foundation pit retaining piles. Background Technique
[0002] Shotcrete is mainly applied to slope protection, foundation pit support, tunnel primary support, etc. Since the thickness of the concrete is generally between 10-20 cm, when constructing in winter, due to the relatively thin thickness of the concrete, it is difficult to ensure the concrete strength by the heat accumulation method, and heat preservation measures need to be taken. Since the foundation pit support is a vertical section, the following deficiencies mainly exist in the conventional covering heat preservation measures:
[0003] 1. It is not easy to fix the covering of the vertical section, the contact with the wall surface is not close, and the space is not tightly closed;
[0004] 2. The inclined surface is made of sandwich cotton, which is heavy, inconvenient to move, and has poor heat preservation effect. Content of the Utility Model
[0005] The purpose of the utility model is to provide a thermal insulation shed for winter construction of shotcrete between foundation pit retaining piles, so as to solve the problems put forward in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0023] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.
[0024] As used herein, the term "exemplary" means "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as superior to or better than other embodiments.
[0025] In addition, for a better description of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can be implemented without some specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.
[0026] The present utility model aims to provide a heat preservation shed, which realizes heat preservation for the shotcrete construction between the foundation pit retaining piles in winter. The specific implementation is as follows:
[0027] Please refer to Figures 1 to 4 , in an embodiment of the present utility model, a heat preservation shed for winter construction of shotcrete between foundation pit retaining piles is arranged on one side of the shotcrete surface 7 and includes:
[0028] A plurality of top plate heat preservation sheds arranged obliquely, and adjacent two top plate heat preservation sheds are detachably connected by a connecting member. A soft lap joint 5 is arranged at one end of the top plate heat preservation shed close to the shotcrete surface 7, and a bottom bracket 2 is fixed at the other end. The bottom bracket 2 is placed on the base surface 8;
[0029] An adjusting unit is connected to the bottom bracket 2 and the base surface 8 for adjusting the degree of fit between the top plate heat preservation shed and the shotcrete surface 7.
[0030] In this embodiment, after the bottom bracket 2 connected to the top plate heat preservation shed is placed on the base surface 8, the top plate heat preservation shed abuts against the shotcrete surface 7 through the soft lap joint 5. At the same time, the inclination angle of the top plate heat preservation shed can be adjusted through the arranged adjusting unit, so as to increase the degree of fit between the soft lap joint 5 and the shotcrete surface 7, and further increase the overall heat preservation effect of the heat preservation shed. The heat preservation shed in this embodiment has a simple structure, is light in weight, is convenient to disassemble and install, and effectively reduces the construction cost.
[0031] Further, please refer to Figure 2 , the top plate heat preservation shed includes a top plate frame 1 and a top plate heat preservation board 9 detachably installed on the top plate frame 1. Preferably, a plurality of purlins 4 are further installed inside the top plate frame 1. The stability of the top plate frame 1 can be effectively increased by arranging the plurality of purlins 4, preventing the top plate heat preservation shed from deforming and affecting the heat preservation effect.
[0032] Exemplarily, in a specific embodiment, the top plate heat preservation board 9 is a polycarbonate heat preservation board.
[0033] Further, please refer to Figure 1 , the bottom bracket 2 is fixedly connected to the top plate frame 1, and the included angle between the bottom bracket 2 and the top plate frame 1 is an acute angle. An inclined brace 3 is installed between the bottom bracket 2 and the top plate frame 1, so as to effectively increase the stability of the top plate frame 1 after being placed at the required position, and at the same time eliminate the risk of fracture at the connection between the bottom bracket 2 and the top plate frame 1.
[0034] Further, please refer to Figure 3 , the adjusting unit includes a bottom support bolt 6 passing through the bottom bracket 2. The bottom support bolt 6 is threadedly connected to the bottom bracket 2. After the bottom bracket 2 is placed on the base surface 8, the bottom support bolt 6 can be manually rotated or rotated by an auxiliary wrench, so that the position of the bottom support bolt 6 relative to the bottom bracket 2 changes, thereby causing the overall angle of the bottom bracket 2 and the top plate frame 1 to change, so that the soft lap joint 5 provided on the top plate frame 1 can be closely attached to the shotcrete surface 7. At the same time, it can also be adjusted adaptively when the flatness of the base surface 8 is relatively poor, and the operation is convenient.
[0035] Further, please refer to Figure 4 , the connecting member includes at least one pin shaft 10. The pin shaft 10 passes through two adjacent top plate frames 1 to connect the two top plate frames 1. In this embodiment, the top plate heat preservation shed, the bottom bracket 2 and the bottom support bolt 6 form an independent unit. After one unit is installed, another unit is installed adjacent to it, and then the two units are connected by the pin shaft 10 to increase the stability of the entire heat preservation shed.
[0036] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
[0037] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
