Description
Technical Field
The application relates to the field of foundation pit support, in particular to an enclosing purlin support.
Background
The supporting of the inner wall of the foundation pit is realized by adopting the enclosing purlin, soil mass of the surface to be supported needs to be trimmed before the enclosing purlin supporting is built in some foundation pits, and the surface to be supported is trimmed and leveled so as to ensure the contact area between the surface to be supported and the enclosing purlin section steel, thereby meeting the stress requirement; when the purlin is built, the profile steel purlin is in comprehensive contact with the surface to be supported, so that force transmission is guaranteed.
In the related art, if a gap exists between the surrounding purlin section steel and the soil body of the surface to be supported, concrete is prepared according to design requirements to be poured and compacted.
However, the compaction is performed through concrete, which is too troublesome in site construction, and in order to reduce compaction points, the surface to be supported needs to be quite smooth and rested in the early stage, so that the workload of the whole construction process is too large, and the efficient construction is not facilitated.
Disclosure of Invention
In order to improve construction efficiency while filling a gap between an enclosing purlin and a surface to be supported, the application provides an enclosing purlin support.
The application provides an enclosing purlin support, which adopts the following technical scheme:
the purlin supporting comprises purlin steel, wherein the purlin steel comprises a contact surface opposite to a surface to be supported; the rubber cushion covers on the contact surface, the rubber cushion with enclose purlin steel and dismantle the connection, the cushion is embedded to be equipped with wire net and a plurality of support piece, the support piece passes the wire net, support piece interval distribution.
By adopting the technical scheme, the rubber cushion is arranged between the contact surface of the enclosing purlin steel and the surface to be supported, the enclosing purlin steel is pressed towards the direction of the surface to be supported, so that the rubber cushion is deformed, the surface of the rubber cushion can be embedded into the rugged surface to be supported, the unevenness of the surface to be supported is compensated, the surface to be supported is propped against the surface to be supported through the enclosing purlin steel, the soil layer of the surface to be supported is prevented from loosening, the rubber cushion is fully contacted between the enclosing purlin steel and the surface to be supported, the transmission of force is ensured, and the good supporting effect can be achieved; the tensile property of the rubber mat is enhanced through the steel wire mesh, when the inner wall of the foundation pit is locally loosened to locally apply force to the rubber mat, the steel wire mesh plays a role in tensile, the possibility of inclination of the local inner wall of the foundation pit is reduced, the steel wire mesh has certain flexibility, slight deformation can be generated, when the concave-convex degree of the surface to be supported is larger, the rubber mat is pressed on the surface to be supported, the steel wire mesh can deform to enable the rubber mat to be attached to the surface to be supported with the concave-convex degree to be tighter, the degree of coordination is higher, and the force transmission is facilitated; the support column plays a role in enhancing the support firmness of the rubber cushion, so that the deformation of the rubber cushion is maintained in a certain range, and thus, when the rubber cushion plays a role in supporting, the rubber cushion can reach higher supporting strength, the rubber cushion is prevented from being pressed down to a larger degree when the inner wall of the foundation pit has a tilting trend, the inner wall of the foundation pit is greatly tilted, and the possibility that the inner wall of the foundation pit loosens and tilts is reduced; in conclusion, the scheme of the application completely meets the supporting strength, meanwhile, the concrete is not required to be compacted, the flatness requirement of the surface to be supported is low, the workload of constructors is greatly reduced, and the construction efficiency is improved while the gap between the surrounding purlin steel and the surface to be supported is filled.
