Abstract
The utility model discloses an H-shaped steel inclined strut positioning device for retaining and protecting a foundation pit. The positioning device comprises a steel base plate, at least one spring a positioning steel bar, and two hinge joint steel plates. One end of the spring is fixed in a buttress formed by concreting in anchoring mode, and the other end is fixedly connected on the bottom surface of the steel base plate. The positioning steel bar is fixedly connected on the bottom of the steel base plate. The two hinge joint steel plates are welded on the middle of the steel base plate in parallel mode. The H-shaped steel comprises two side edge plates vertically arranged and a web plate connected with the two side edge plates, wherein one of the two side edge plates abuts against the positioning steel bar, and the web plate inserts into the middle of the two hinge joint steel plates. When a diagonal bracing for retaining and protecting is installed, the gravity of the H-shaped steel can condense the spring to enable the H-shaped steel to overcome the defect of a length error and abut against just in the steel base plate. Therefore, the H-shaped steel can be temporarily fixed with no need to be cut for two times. The installing accuracy and safety of the H-shaped steel are guaranteed, and cost is saved.
Description
Technical field
The utility model relates to the H shaped steel diagonal brace positioner that a kind of pattern foundation pit supporting structure is used.
Background technology
At present, adopt inner support or campshed to add the form of anchor pole for pattern foundation pit supporting structure in the industry more.Generally do not adopt under normal circumstances H shaped steel diagonal brace in the foundation ditch, but, then must adjust former design support pattern when not clear and work progress Central Plains design support pattern can not be implemented maybe can not satisfy safety requirements when foundation ditch periphery geological conditions.Therefore H shaped steel diagonal brace mode can be adjusted and strengthens former design support pattern.
Existing diagonal brace major way has steel pipe and H shaped steel.Temporary fixed for H shaped steel diagonal brace, temporarily without reliable temporary fixed mode, site operation mainly adopts the mid-event control mode, and connecting portion about the H shaped steel is lengthened temporarily or cuts by on-the-spot physical length.
When H shaped steel is long, need to cut by actual requirement, this will cause waste of material, does over again frequent, and has increased the difficulty of construction progress control; When H shaped steel is too short, need to utilize solder technology that it is increased, this will cause quality and precision to be difficult to ensure, does over again frequent, and has increased the difficulty of construction progress control; Simultaneously, existing main dependence crane hangs for a long time surely aspect temporary fixed, just can withdraw after a period of time is finished in welding, thereby cause the rising of cost.
