Abstract
The utility model relates to a large-span cover beam bearing force supporting device which comprises first bearing base plates, beret piece layers, supporting frame bodies and mold supporting layers. The first bearing base plates are evenly distributed on the hardened ground, the beret piece layers are arranged on the first bearing base plates, the supporting frame bodies are erected on the beret piece layers in a criss-cross mode and are connected through buckling pieces, the mold supporting layers are arranged on the supporting frame bodies and used for supporting molds, and the mold supporting layers comprise transverse base plates evenly arranged on the lower portions, longitudinal base plates evenly arranged on the transverse base plates and mold supporting columns evenly distributed on the longitudinal base plates. The large-span cover beam bearing force supporting device is convenient to mount, balanced in stress, high in bearing capacity, low in requirement for ground pretreatment in the earlier stage, low in requirement for terrain and geology and high in universality.
Description
Technical field
The utility model relates to a kind of bent cap fastening, is specifically related to a kind of large span bent cap load bracing or strutting arrangement.
Background technology
Along with the development of China's speedway, large span prestressed concrete bent cap can be widely used in highway bridge, and it is attractive in appearance that it not only increases bridge, can greatly improve the ground space under bridge simultaneously, outstanding in the city area advantage of ground space restriction.For the engineering characteristic of large span prestressed concrete bent cap, generally adopt the construction of conventional bracket (φ 48*3.5mm steel pipe full framing) method, or adopt the construction of bracket (anchor ear) method form erecting technology.
Construct at Du Dun (large span) pre-stressed concrete coping, if adopt the construction of bracket (anchor ear) method form erecting technology, exist section steel manufacture investment large, engineering quantity is large, instrument versatility poor (only a project is used), the series of problems such as technical difficulty is high, and installing space is narrow, palpus main equipment coordinative construction.Adopt the construction of conventional bracket (φ 48*3.5mm steel pipe support) method, support is pacified, is torn technology maturation open, and fast and safely, but basic specially treated workload is larger, long construction period, much time wealth.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, provides a kind of and can effectively improve the large span bent cap load bracing or strutting arrangement of setting up efficiency, stable support stress point.
For achieving the above object, the technical scheme of taking is:
A kind of large span bent cap load bracing or strutting arrangement, include and be uniformly arranged on load backing plate one on hardened ground, be arranged on shellfish thunder lamella on load backing plate one, set up crisscross the bracing frame main body connecting by fastener and be arranged on the mould support layer for supporting mould in bracing frame main body on described shellfish thunder lamella, described mould support layer comprises the uniform horizontal backing plate of bottom, uniform longitudinal backing plate and the uniform mould support post being arranged on longitudinal backing plate being arranged on horizontal backing plate of being arranged on.
The strong point of described bracing frame bottom part body is provided with the load backing plate two across shellfish thunder lamella.
Described load backing plate one, load backing plate two, horizontal backing plate and longitudinal backing plate all can adopt channel-section steel, H shaped steel or i iron.
In described bracing frame main body, be provided with the shearing support of oblique pull, shearing support is connected by fastener with bracing frame main body.
Described mould support post is jack or hydraulic cylinder equal altitudes adjustable prop.
Described bracing frame main body side is by the hinged mounting attachment that is erected with of fastener.
Adopt technique scheme, obtained beneficial effect is:
The utility model is easy for installation, stress equalization, bearing capacity are strong, and require low early stage for ground pretreatment, for landform and geology require low, highly versatile.
