Abstract
The utility model discloses a whole ann of bridge cantilever construction tears protector open, including the bridge pier shaft the bilateral symmetry of bridge pier shaft bottom is provided with the guardrail, bar formation that this guardrail was parallel to each other by guardrail horizon bar and duo gen, the reinforcing bar is " L " shape, and the inner of this reinforcing bar crosspiece forms the screw rod through shelling rib straight thread rolled thread processing, during the screw rod stretches into the pre -buried sleeve in bridge pier shaft bottom, both threaded connection, each reinforcing bar of homonymy erect the section through linking together from last many guardrail horizon bars that down set up, erecting of guardrail horizon bar and reinforcing bar section is welded mutually to the perpendicular section of fence horizon bar perpendicular to reinforcing bar. The utility model relates to a rationally, simple structure, it is easy to implement, and it is convenient, with low costs to install, can effectively improve the stability of atress and the security of construction operation, all is suitable for in the construction of different types of rridges cantilever.
Description
Technical field
The utility model belongs to technical field of bridge engineering, specifically, tears safety guard open in particular to bridge cantilever construction entirety peace.
Background technology
For many years, continuous rigid frame bridge cantilever casting construction is widely used in highway, municipal administration bridge field and develops. At present, the construction of encorbelmenting of common bridge mainly relies on bracket, bears frame or built-up type support system, stress condition owing to encorbelmenting has the features such as cantilever span is big, Load concentration, Construction treatment are complicated, therefore, ensure that the stable safety and quality control that whole bridge is encorbelmented construction of support system has most important relation, and each has something to recommend him at eminence unsettled place construction safety security problem, but all base oneself upon place without firm. Existing unsettled high-rise working mainly adopts following two kinds of forms of construction work:
1, hanging basket or hang cage construction: lift must be adopted, operator must special messenger's special plane, install and assembling content many, have cost high maintenance require high, turnover is difficult, have enough to meet the need the deficiencies such as slow;
2, rack construction: utilize steel pipe, rod member or synthetic materials to carry out the support system assembled, the rod member at support node place is eccentric connection, transmits load and internal force by skid resistance, thus reduces its supporting capacity; The impact of the connection quality of quality fastener of fastener node own and workman's operation is remarkable, and the more high security risk in hanging operation position is more big.
Practical novel content
Technical problem to be solved in the utility model is to provide the bridge cantilever construction entirety peace that a kind of structure is simple, security is good to tear safety guard open.
The technical solution of the utility model is as follows: a kind of bridge cantilever construction entirety peace tears safety guard open, comprise bridge pier body, it is characterized in that: the zygomorphy bottom described bridge pier body is provided with guardrail, the reinforcing bar that this guardrail is parallel to each other by the horizontal bar of guardrail and Duo Gen is formed, described reinforcing bar is " L " shape, the inner of this reinforcing bar crosspiece is processed to form screw rod by stripping rib straight thread rolled thread, described screw rod stretches in the sleeve buried in advance bottom bridge pier body, both are threaded, linked together by the horizontal bar of many guardrails arranged from top to bottom with the perpendicular section of each reinforcing bar in side, the horizontal bar of guardrail welds mutually with the perpendicular section of reinforcing bar, and the horizontal bar in hurdle is perpendicular to the perpendicular section of reinforcing bar.
Adopting above technical scheme, be embedded in advance by joint sleeve in pier body when bridge pier body is built, sleeve bear one end outwardly, is tamped with sponge.After pier body concrete form removal, take out the sponge burying in sleeve in advance; Adopting hanging basket lifting operation, by the reinforcing bar of machine-shaping together with burying sleeve connection in advance, just define operation platform load-bearing skeleton, then welding is protected and is blocked horizontal bar, lays plank, and plank two ends adopt galvanized steel wire hoop around fixing. It thus is seen that the utility model not only structure is simple, easy for installation, quick, cost is low, and can effectively improve the security of the stability by power and constructing operation.
As preferably, being equipped with plank on described guardrail, this plank is supported jointly by the horizontal section of each reinforcing bar of guardrail, and adopts galvanized steel wire hoop around fixing between plank and reinforcing bar.
Useful effect: the utility model is reasonable in design, structure is simple, implements easily, and it is convenient to install, and cost is low, can effectively improve the security of the stability by power and constructing operation, all applicable in different types of rridges cantilever construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlargement figure of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the zygomorphy bottom bridge pier body 1 is provided with guardrail 2, and the reinforcing bar 21 that this guardrail 2 is parallel to each other by the horizontal bar 22 of guardrail and Duo Gen is formed. In the present embodiment, the number of reinforcing bar 21 is preferably four, and each reinforcing bar 21 is bent into " L " shape, and the inner of this reinforcing bar 21 crosspiece is processed to form screw rod by stripping rib straight thread rolled thread, and screw rod stretches in the sleeve 3 buried in advance bottom bridge pier body 1, and both are threaded. Being linked together by the horizontal bar 22 of many guardrails arranged from top to bottom with the perpendicular section of each reinforcing bar in side 21, the horizontal bar of guardrail 22 welds mutually with the perpendicular section of reinforcing bar 21, and the horizontal bar in hurdle 22 is perpendicular to the perpendicular section of reinforcing bar 21. Being equipped with plank 4 on guardrail 2, this plank 4 is supported jointly by the horizontal section of each reinforcing bar 21 of guardrail 2, and adopts galvanized steel wire hoop around fixing between plank 4 and reinforcing bar 21.
Construction process of the present utility model is as follows:
Being embedded in pier body in advance by joint sleeve 3 when bridge pier body 1 is built, sleeve 3 bear one end outwardly, is tamped with sponge. After pier body concrete form removal, take out the sponge burying in sleeve 3 in advance; Adopting hanging basket lifting operation, by the reinforcing bar 21 of machine-shaping with burying sleeve 3 in advance and link together, just define operation platform load-bearing skeleton, then welding is protected and is blocked horizontal bar 33, finally lays plank 4, and plank 4 two ends adopt galvanized steel wire hoop around fixing.
The specification of the horizontal bar 22 of above-mentioned reinforcing bar 21, guardrail, sleeve 3 and plank 4 is determined according to actual needs, does not repeat at this.
