Description
Technical Field
The utility model relates to a foundation ditch construction technical field especially relates to a prevent strutting arrangement of foundation ditch deformation.
Background
In the prior art, an inner support mode is often adopted for controlling the deformation of an enclosure wall structure in foundation pit construction, and a steel support structure is the most common mode and has the characteristics of high rigidity, high bearing capacity and random layout. However, in practical application, the application of the axial force of the inclined strut is limited due to the included angle between two adjacent enclosure walls, so that the control on the deformation of the foundation pit structure is influenced. The steel support stress node is analyzed, when the steel support inclined strut between two adjacent wall surfaces exerts axial force, the axial force is decomposed into vertical force and horizontal force, and the vertical force and the horizontal force of the steel support are easy to damage the soft structure and slide due to the fact that the pit wall is generally of a soft structure, and the support requirement cannot be met.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a supporting device for preventing the deformation of a foundation pit.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a prevent strutting arrangement of foundation ditch deformation, includes pitted wall and ejector pin, the lower extreme of ejector pin can be dismantled and is connected with the flange seat, and the one end that the ejector pin was kept away from to the flange seat is connected with T shape hinge bar, and one side of T shape hinge bar is equipped with vertical board, and vertical board is close to one side of pitted wall and installs the cross post, and the cross post inserts in the pitted wall, and one side that the cross post was kept away from to vertical board is installed the hinge lug that the symmetry set up, T shape hinge bar rotates to be connected in the hinge hole on the hinge lug.
Preferably, the cross column is perpendicular to the vertical plate and is integrally cast.
Preferably, the cross column is provided with vertical pieces arranged at equal intervals.
Preferably, one end of the ejector rod, which is close to the flange seat, is connected with a flange plate, and the flange plate is connected with the flange seat through a connecting bolt.
Preferably, an elastic gasket is arranged between the flange plate and the flange seat.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, the ejector pin bears along its axial pressure, this pressure is according to mechanics law, this pressure resolvable is vertical direction and horizontal direction's component, wherein vertical direction and hole wall offset the effort of cross post, the plane and the vertical component of cross post are perpendicular, the pressure that receives is little, difficult extrusion hole wall, stability is better, the same reason, horizontal direction's component and hole wall offset the effort of vertical board, difficult appearance slides, thereby, guarantee that the ejector pin can bear great pressure, and simultaneously, the contained angle between ejector pin and the hole wall is adjustable, and the suitability is better.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural diagram of a vertical plate and a cross column.
In the figure: the support device comprises a top rod 1, a flange seat 2, a connecting bolt 3, a T-shaped hinge rod 4, a hinge lug 5, a flange plate 6, a vertical plate 7, a cross column 8, a hinge hole 9, a vertical sheet 10 and a pit wall 11.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a supporting device for preventing foundation pit deformation, including pit wall 11 and ejector pin 1, the lower extreme of ejector pin 1 can be dismantled and is connected with flange seat 2, the one end that ejector pin 1 was kept away from to flange seat 2 is connected with T shape hinge bar 4, one side of T shape hinge bar 4 is equipped with vertical plate 7, vertical plate 7 is close to one side of pit wall 11 and installs cross post 8, cross post 8 inserts in pit wall 11, one side that vertical plate 7 kept away from cross post 8 is installed the hinge lug 5 that the symmetry set up, T shape hinge bar 4 rotates to be connected in hinge hole 9 on hinge lug 5.
Wherein, cross post 8 sets up with vertical plate 7 is perpendicular, and for integrative casting shaping, vertical component can be offset to cross post 8, and horizontal direction component can be offset to vertical plate 7, and integrative casting shaping intensity is higher.
Install the riser 10 that equidistant setting was gone up to cross post 8, the setting of cross post 8 and riser 10 can hinder vertical plate 7 in horizontal, vertical and fore-and-aft direction activity, it is difficult not hard up to make it, improve its fastness, the one end that ejector pin 1 is close to flange seat 2 is connected with ring flange 6, ring flange 6 passes through connecting bolt 3 and is connected with flange seat 2, make things convenient for the dismouting, be equipped with the gasket between ring flange 6 and the flange seat 2, utilize gasket's resilience force, improve ring flange 6, joint strength between flange seat 2 and the connecting bolt 3.
