Abstract
The utility model relates to a lattice type foundation pit cross brace support which comprises 4 upright posts arranged according to 4 vertexes of a rectangle, wherein a bottom plate is welded at the bottom of each upright post, a plurality of layers of cross rods are welded among the 4 upright posts according to 4 sides of the rectangle, two parallel bearing beams are welded at the tops of the 4 upright posts, and two parallel limiting beams with a certain distance are welded between the top surfaces of the two bearing beams. The steel pipe pile support frame is used for replacing a steel pipe pile to support a cross brace during construction of a bearing platform, the support is of a lattice type steel structure, the steel bars of the bearing platform can penetrate through the middle of the support, normal arrangement of the steel bars of the bearing platform cannot be influenced, the steel bars and the steel bars of the bearing platform are poured into concrete together, and construction quality of the bearing platform can be guaranteed.
Description
Technical Field
The utility model belongs to the field of bridge construction, relates to construction of a bridge bearing platform, and particularly relates to a lattice type support for vertically supporting a bearing platform foundation pit cross brace during bearing platform construction.
Background
The bearing platform of the land bridge usually needs to be excavated to carry out construction. In order to prevent the foundation pit from collapsing, steel sheet piles, concrete piles and the like are arranged on the periphery of the inner side of the foundation pit for enclosure, and cross braces are arranged between the opposite piles in a manner of crossing the foundation pit to prevent the enclosure piles from inclining due to the pressure of the soil body. The wales are usually made of large-diameter steel pipes. For large foundation pits, the span of the cross brace is large, and the vertical brace is required to be arranged below the cross brace to support the cross brace.
In the construction at present, the vertical support generally adopts the steel-pipe pile, and before excavation of the foundation pit, the vertical support is driven into the soil according to the design position in advance, and when the cross support is installed after excavation of the foundation pit, the cross support is supported on the steel-pipe pile. Because the support of the steel pipe pile to the cross brace needs to be kept in a consistent manner in the construction process of the bearing platform, the steel pipe pile and the steel bar of the bearing platform are poured into concrete finally.
The steel pipe pile is adopted as a cross brace support, and the following problems mainly exist:
(1) as soil can enter the interior of the steel pipe pile during the inserting and driving process and the steel pipe pile is difficult to clean, the steel pipe pile can corrode concrete of the bearing platform when being poured into the bearing platform, and the pouring quality of the bearing platform is influenced;
(2) the bearing platform steel bars are dense, and the steel pipe pile is large in size, so that the normal arrangement and installation of the bearing platform steel bars can be influenced, and the construction quality of the bearing platform is further influenced.
Disclosure of Invention
The utility model aims to solve the problems and provide a lattice type bearing platform foundation pit cross brace support, wherein a steel pipe pile is replaced to support a foundation pit cross brace during bearing platform construction, the steel pipe pile is prevented from influencing the installation of a bearing platform steel bar, and the construction quality of the bearing platform is ensured.
The technical scheme of the utility model is as follows:
the utility model provides a lattice formula foundation ditch stull support which characterized in that: including the 4 stands that set up according to 4 summits of rectangle, a bottom plate of bottom welding of every stand, 4 stand welds the multilayer horizontal pole according to 4 limits of rectangle within a definite time, and two spandrel girders that are parallel to each other are welded at the top of 4 stands, welds two spacing roof beams that are parallel to each other and have a determining deviation between two spandrel girders top surfaces.
The auxiliary supporting device for the foundation pit cross brace is used for replacing the steel pipe pile to support the cross brace when a bearing platform is constructed, so that the adverse effect of the steel pipe pile on the bearing platform can be avoided; the utility model is of a lattice structure, the bearing platform steel bars can pass through the middle, the normal arrangement of the bearing platform steel bars can not be influenced, and the construction quality of the bearing platform can be ensured.

fig. 3 is a schematic view of the state of use of the present invention.
Detailed Description
As shown in fig. 1 and 2, the utility model comprises 4 upright posts 1 arranged according to 4 vertexes of a rectangle, a bottom plate 2 is welded at the bottom of each upright post, a multi-layer cross rod 3 is welded among the 4 upright posts according to 4 sides of the rectangle, two bearing beams 4 which are parallel to each other are welded at the tops of the 4 upright posts, and two limiting beams 5 which are parallel to each other and have a certain distance are welded between the top surfaces of the two bearing beams.
When the utility model is implemented, the upright posts, the cross rods, the bearing beams and the limiting beams are all made of I-steel.
When the utility model is used for bearing platform construction, the initial vertical support of the bearing platform foundation pit transverse support still adopts the traditional steel pipe pile support. After the cushion layer of the bearing platform is constructed, the bracket is processed according to the height from the top surface of the cushion layer to the bottom of the cross brace, and the two limiting beams at the top part are not welded firstly when the bracket is processed.
As shown in fig. 3, the bracket is placed below the wale 6, so that the two bearing beams 4 are perpendicular to the axis of the wale and supported at the bottom of the wale, and then the two limit beams 5 are welded to two sides of the wale in a manner of clinging to each other.
After the support is installed, the steel pipe pile is cut off, so that the cross brace is supported by the support, and the stress conversion is completed. And then, the bearing platform steel bars are installed, and because the steel bars are of a lattice structure, the steel bars can pass through the middle of the bracket, and the normal arrangement of the steel bars is not influenced. After the reinforcing steel bars are installed, bearing platform concrete is poured, and the support and the bearing platform reinforcing steel bars are poured into the bearing platform concrete together.
