[0002] The foundation pit support device is an important device to ensure the safety and stability of the foundation pit construction. With the continuous development of modern construction technology and the diversification of engineering needs, the size and shape of the foundation pit are becoming increasingly diversified, which requires the foundation pit support device to have higher adaptability and flexibility.
[0003] Traditional foundation pit support devices usually use a single fixed-length horizontal and vertical beam structure, and support the soil blocks on the side walls of the foundation pit by inserting prefabricated plugs into the horizontal and vertical beams and moving them into the foundation pit.

[0033] Please refer to Figure 1-5 As shown, this embodiment provides an assembled foundation pit support device 100, which includes a mounting frame 110 and a plug plate 111. The mounting frame 110 is installed at the excavation opening 11a of the foundation pit 200 to limit the size of the excavation opening 11a of the foundation pit 200, so that construction personnel can excavate at the excavation opening 11a limited by the mounting frame 110. Further, the mounting frame 110 includes a beam 121, and at least one beam 121 is provided to splice to form a cross beam 131 adapted to the length L2 of the foundation pit 200, and / or at least one beam 121 is provided to splice to form a longitudinal beam 132 adapted to the width of the foundation pit 200. The plug plate 111 penetrates the cross beam 131 and / or the longitudinal beam 132 and can move relative to the direction of the foundation pit 200.
[0034] According to the above scheme, in some embodiments, three beams 121 are provided to be spliced to form a cross beam 131 adapted to the length L2 of the foundation pit 200 , and one beam 121 is provided to form a longitudinal beam 132 adapted to the width of the foundation pit 200 .
[0035] According to the above scheme, in other embodiments, four beams 121 can be spliced to form a cross beam 131 that matches the length L2 of the foundation pit 200, and two beams 121 can be set to form a longitudinal beam 132 that matches the width of the foundation pit 200.
[0036] In other embodiments, transverse beams 131 and longitudinal beams 132 composed of different numbers of beam frames 121 can be set according to the length and width of the foundation pit 200, so that the lengths of the transverse beams 131 and longitudinal beams 132 can be flexibly adjusted according to the actual size of the foundation pit 200 to meet the support of the side walls of the foundation pit 200, improve the adaptability of the assembled foundation pit support device 100 to foundation pits 200 of different sizes, and promote the convenience of the support device during installation and use, thereby ensuring an excellent support effect on the foundation pit 200, improving the construction safety of the foundation pit 200, and there is no need to prepare a variety of transverse and longitudinal beams 132 of different lengths for adaptation, thereby reducing construction costs, construction complexity and management difficulty.
[0037] According to the above scheme, specifically, the beam frame 121 includes a first beam plate 141 and a second beam plate 142, and the first beam plate 141 and the second beam plate 142 are spaced apart to form a limiting opening 14a for limiting the insert plate 111. It can be understood that the insert plate 111 can pass through the limiting opening 14a and thus can move toward the excavation opening 11a of the foundation pit 200 under the limiting action of the limiting opening 14a, that is, to move closer to or away from it.
[0038] Moreover, in this embodiment, the beams 121 are spliced along the first direction to form the cross beam 131 , and the beams 121 are spliced along the second direction to form the longitudinal beam 132 ; further, the insert plate 111 passes through the limit opening 14a along the third direction and extends toward the foundation pit 200 .
[0039] Preferably, the mounting frame 110 further includes a fixing plate 122, and the fixing plate 122 is installed between any two adjacent beams 121, or the fixing plate 122 is installed at both ends of any beam 121. It can be understood that this setting is to fix the beam 121 located on the cross beam 131 abutting against the longitudinal beam 132 and the beam 121 on the longitudinal beam 132 abutting against the beam 121. At the same time, the beams 121 of the cross beam 131 are also fixed by the fixing plate 122, and the beams 121 of the longitudinal beam 132 are fixed by the fixing plate 122. 21 are also fixed by the fixing plate 122. Optionally, in this embodiment, fixing screws are used to penetrate two adjacent beam bones 121 and the fixing plate 122 on the cross beam 131, and fixing screws are used to penetrate the beam bones 121 on the cross beam 131 that abut against the longitudinal beam 132 and the fixing plate 122; as a variation, in other embodiments, the fixing plate 122 can be designed to be mutually engaged with the beam bones 121 on the cross beam 131 and the longitudinal beam 132 to fix each beam bone 121.
[0040] Preferably, the length range of the beam 121 is between 1 / 4 and 1 of the length L2 of the foundation pit 200, or the length range of the beam 121 is between 1 / 3 and 1 of the width of the foundation pit 200; it is understandable that the foundation pit 200 is usually configured as a rectangular structure, so the foundation pit 200 has different lengths and widths. Optionally, in this embodiment, the length of the beam 121 of the crossbeam 131 is designed to be 1 / 3 of the length L2 of the foundation pit 200, and the length of the beam 121 of the longitudinal beam 132 is designed to be the same as the width of the foundation pit 200; in other embodiments, since the foundation pit 200 is larger, the length of the foundation pit 200 is longer and the width of the foundation pit 200 is wider, it is necessary to design more beams 121 to be assembled into the crossbeam 131 than in the above-mentioned embodiments, which is not limited here.
[0041] Preferably, the assembled foundation pit support device 100 further includes a reinforcement member 112, which is assembled on the cross beam 131 and fixedly connected to the longitudinal beam 132, or the reinforcement member 112 is assembled on the longitudinal beam 132 and fixedly connected to the cross beam 131; it can be understood that the reinforcement member 112 in this embodiment is arranged at the connection between the cross beam 131 and the longitudinal beam 132 to reinforce the connection between the cross beam 131 and the longitudinal beam 132; in addition, the assembled support device further includes a guardrail insert 113, which is installed on the beam frame 121 or installed on the reinforcement 112; the assembled support device also includes a guardrail frame 114, which can be detachably installed on the guardrail insert 113; the purpose of setting the guardrail is that when the insert plate 111 is inserted into the depth of the foundation pit 200 under the limiting action of the limiting opening 14a, the position at the excavation opening 11a of the foundation pit 200 is not blocked. By setting the guardrail and installing the guardrail at the guardrail insert 113, the excavation opening 11a of the foundation pit 200 is blocked to prevent pedestrians from accidentally falling into the foundation pit 200.
[0042] Preferably, the assembled foundation pit support device 100 also includes a reinforcing rod 115, which is detachably mounted on the inner side of the plug plate 111, and the installation direction of the reinforcing rod 115 is along the first direction or along the second direction so as to be perpendicular to the moving direction of the plug plate 111 along the third direction; it is understandable that the length of the reinforcing rod 115 can be set to one or more, and the length of the reinforcing rod 115 is less than the length of the crossbeam 131. The purpose of this structure is to be able to install one reinforcing rod 115 on all the plug plates 111 along the first direction and fix the plug plates 111, and to be able to install more than one reinforcing rod 115 on different numbers of plug plates 111 along the first direction and fix different numbers of plug plates 111, thereby achieving the effect of fixing all the plug plates 111; it is understandable that the installation direction of the reinforcing rod 115 is installed along the second direction on the plug plates 111 arranged along the second direction, which also achieves the same effect as the above-mentioned scheme.
[0043] Preferably, the foundation pit support device 100 also includes a support rod 116, and the support rod 116 is configured to be installed between two cross beams 131 along the second direction, or the support rod 116 is installed between two longitudinal beams 132 along the first direction. As the foundation pit 200 is continuously excavated, the soil at the excavation opening 11a of the foundation pit 200 becomes increasingly loose. Therefore, the support rod 116 is provided to support the cross beam 131 or the longitudinal beam 132, so that the soil at the excavation opening 11a is not easily loosened, thereby promoting the protective effect of the foundation pit 200 support.
[0044] In summary, the utility model provides an assembled foundation pit support device, which forms a crossbeam that matches the length of the foundation pit by setting at least one beam frame, and / or forms a longitudinal beam that matches the width of the foundation pit by setting at least one beam frame. The user can set crossbeams and longitudinal beams composed of different numbers of beam frames according to the length and width of the foundation pit, so that the lengths of the crossbeams and longitudinal beams can be flexibly adjusted according to the actual size of the foundation pit to meet the support of the side walls of the foundation pit, improve the adaptability of the assembled foundation pit support device to foundation pits of different sizes, and promote the convenience of the support device during installation and use, thereby ensuring an excellent support effect on the foundation pit, improving the construction safety of the foundation pit, and there is no need to prepare a variety of cross and longitudinal beams of different lengths for adaptation, which reduces construction costs and also reduces construction complexity and management difficulty.
