Abstract
A kind of telescopic folding steel support, the utility model relates to Construction of Civil Engineering field, its structure is: the end of cross support (1) is provided with baffle plate (2), the end of cross support (1) is socketed with bracing frame (3), the one ends wound of bracing frame (3) is on bearing pin (4), bearing pin (4) is flexibly connected with cross support (1), the other end of bracing frame (3) is fixedly connected with gripper shoe (5), gripper shoe (5) contacts with interior Steel-wood forming board (6), and support frame as described above (3), bearing pin (4), gripper shoe (5) all have 4.The beneficial effects of the utility model are: the physical dimension of auxiliary lower beam slab of the present utility model can meet design requirement, thickness of protection tier can be guaranteed; solve the technical barrier that bridge is built and runed; thorough this common quality defect of solution hollow slab girder, serves positive role to the degree of safety and durability promoting hollow slab girder.Though low at cost.
Description
Technical field
The utility model relates to Construction of Civil Engineering field, particularly the telescopic folding steel support of one.
Background technology
In recent years, prestressed hollow slab beam is at civil construction project (highway, railway, urban road) etc. be widely used in engineering, arranging of cavity all adopts traditional air bag technique, but air bag has inhomogeneous deformation under uneven force environment, the physical dimension of beam slab is difficult to meet design requirement, thickness of protection tier is difficult to be guaranteed, constantly building along with high-grade highway at present, bridge build and operation technology are had higher requirement, thoroughly to solve this common quality defect of hollow slab girder, a kind of method in the urgent need to effective pre-cast hollow slab goes to substitute traditional method for prefabricating in the past.
Summary of the invention
A kind of telescopic folding steel support is provided for the problems referred to above the utility model, it is characterized in that: cross support (1) is made up of channel-section steel, (1) is provided with pin shaft hole B(8 to cross support), one end of expansion link (2) be socketed in cross support (1) upper and by bearing pin A(3) fixing, the other end of expansion link (2) is fixed with baffle plate (4), baffle plate (4) is provided with pin shaft hole A(7), the internal sleeve of baffle plate (4) be connected to telescopic baffle (6) and by bearing pin B(9) fixing, the periphery of baffle plate (4) and telescopic baffle (6) is fixed with template (5), described expansion link (2), baffle plate (4), telescopic baffle (6) all has 4.
The utility model uses like this: first that bottom model sheetinstallat is good, then by good and sound to same direction for cross support (1), again by each and every one expansion link (2) of cross support (1) end, baffle plate (4) and telescopic baffle (6) fix, all cross supports (1) are being stringed together with steel cable, then inner formword (5) is being fixed on baffle plate (4) and telescopic baffle (6), cast-in-situ steel reinforced concrete between inner formword (5) and exterior sheathing, cross support (1) will be extracted out by steel cable after treating concrete setting again inner formword (5) to be extracted out, to ensure that the notch of each cross support (1) is placed on the same side when cross support (1) is installed, so just can ensure after construction completes, draw with the opposite side one of steel cable from cross support (1), expansion link (2) on cross support (1), baffle plate (4), telescopic baffle (6) is by bearing pin A(3) rotate backward, so just can very easily folding steel support all be pulled out.
The beneficial effects of the utility model are: the physical dimension of auxiliary lower beam slab of the present utility model can meet design requirement, thickness of protection tier can be guaranteed; solve the technical barrier that bridge is built and runed; thorough this common quality defect of solution hollow slab girder, serves positive role to the degree of safety and durability promoting hollow slab girder.Though low at cost.
