Description

Technical Field

[0001] The utility model belongs to the technical field of engineering construction, and in particular relates to a multi-directional adjustable socket-and-spigot assembly type foundation pit protective railing device. Background Art

[0002] The depth of the excavation pit supported by steel sheet piles at the construction site is generally more than 2m. According to the specifications, a guardrail must be installed for edge operations. The upper pole should be 1.2m above the ground, and the lower pole should be set between the upper pole and the footboard with a skirting board of not less than 180mm in height, and the spacing between the guardrail uprights should not be greater than 2m. In general, scaffolding steel pipes are used as crossbars and uprights, and steel pipe fasteners are used to connect each node to form a protective structure, and skirting boards are installed at the bottom. The following problems may be encountered during the installation and construction process:

[0003] 1) Inconvenient construction: The poles need to be directly inserted into the top soil layer of the foundation pit by machinery. The presence of stones in the upper miscellaneous fill makes it difficult to insert or the spacing between the poles is uneven after insertion, and the line shape is not smooth;

[0004] 2) Time-consuming and labor-intensive: Fasteners are required to connect each node, and at least 2 to 3 workers are required to cooperate in the installation process. When the size of the foundation pit (foundation trench) is large, there are many fastener nodes, which is time-consuming and labor-intensive;

[0005] 3) Low standardization: Since there is no standard size for each component of the guardrail, after installation, the steel pipes are often not straight, the horizontal bars are uneven or not high enough, resulting in the size of the protective structure not meeting the requirements of the specification and poor appearance. The skirting board is easily damaged during installation and removal, resulting in waste. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a multi-directional adjustable socket-and-socket assembled foundation pit guardrail device to solve the problems of low standardization, unsightly appearance, inconvenient installation and complicated installation of accessories of scaffolding steel pipes used for foundation pit (foundation trench) protection.

A transverse adjustable slide groove is provided along the length direction of the base. The transverse pressure plate is plugged and fixed in the transverse adjustable slide groove. The plug-in seat is provided with a vertically adjustable slide groove. The plug-in seat is plugged and fixed on the foundation pit supporting steel sheet pile through the vertical adjustable slide groove.

[0008] The beneficial effects of the utility model are as follows: compared with the prior art, by setting a bidirectionally adjustable base and a transverse pressure plate, and arranging a transversely adjustable slide groove and a vertically adjustable slide groove on the bidirectionally adjustable base, the utility model has the advantages of convenient construction, convenient installation and disassembly, and a high degree of standardization.

[0009] Preferably, the base includes a first channel steel, thick steel bars are welded inside both sides of the flange of the first channel steel, and a gap is left between the thick steel bar and the inner side of the web of the first channel steel to form the transverse adjustable slide groove; through the setting of the above structure, the forming of the transverse adjustable slide groove is more convenient, and the connection with the transverse pressure plate is also more convenient.

[0010] Preferably, the socket includes a second channel steel and a third channel steel, two second channel steels are provided, one end between the two second channel steels is welded and fixed by the third channel steel, the webs of the two second channel steels are relatively distributed, and a gap is left between the two second channel steels to form the vertical adjustable slide groove; through the setting of the above structure, the forming of the vertical adjustable slide groove is more convenient, and it is also more convenient to connect with the foundation pit support steel sheet piles.
