Abstract
The invention discloses an embedding positioning construction method for a vertical multi-bundle pre-stressed steel strand. The method comprises the steps of manufacturing a vertical mold tool, that is, designing the shape and the size of a pressure bearing plate according to an upper structure, manufacturing a pressure bearing plate positioning tool by using bamboo plywood and square timber according to the proportion of 1:1, and cutting the pressure bearing plate positioning tool into seven small blocks; mounting the small pressure bearing plate positioning tool blocks, that is, mounting the small pressure bearing plate positioning tool blocks at the top end of a template one by one according to determined control points on the basis of an established lower structure template and a threaded lower steel strand, processing a mortise-and-tenon joint by using the square timber on the pressure bearing plate positioning tool to control the overall accuracy of the pressure bearing plate positioning tool, and reinforcing the mortise-and-tenon joint and the established lower structure template together for subsequent process construction. The problems that the vertical multi-bundle pre-stressed steel strand is difficult to position and the accuracy cannot be guaranteed in construction are solved. The method has the characteristics of high construction speed, accurate positioning and simple and convenient mounting, the whole positioning working period is eliminated, the stability is high, the embedding quality of an embedded part is effectively guaranteed, and the positioning tool can be reused.
Description
Technical field
The present invention relates to a kind of pre-buried positioning construction method of vertical multi beam prestress wire.
Background technology
Along with fast development and the construction of Chinese bridge cause, high, new, sharp object of construction production continues to bring out along with project organization and aesthetic, the continuous novelty of design, more and more higher to the precision controlling of engineering in construction, construction period, especially the accuracy of built-in fitting location is difficult to ensure, the pre-buried location of vertical multi beam prestress wire, and the accuracy of its location directly affects the installation location of superstructure.In current work progress, major part is all adopt groined type reinforcing bar to fix, this kind of fixing reliability not only lacking firm position, and may cause the damage of bellows in groined type reinforcement welding fixation procedure.
Summary of the invention
Its object of the present invention is just the pre-buried positioning construction method providing a kind of vertical multi beam prestress wire, solve vertical multi beam prestress wire location difficulty in construction and precision controlling cannot guaranteed problem, have that speed of application is fast, accurate positioning, feature be simply and easily installed, and save the overall work cycle of location, there is good stability, effectively ensure that the pre-buried quality of built-in fitting, orientation tool can be reused.
Realize above-mentioned purpose and the technical scheme taked, comprise step,
1) formwork erection instrument is made
According to design shape and the size of superstructure bearing plate, be made into 1:1 ratio bearing plate orientation tool with bamboo slab rubber and the lumps of wood, then bearing plate orientation tool is cut into 7 fritters;
2) bearing plate orientation tool is installed
Based on substructure shuttering and bottom steel strand, on template top by determining that position, control point installs bearing plate orientation tool one by one, utilize the lumps of wood on bearing plate orientation tool to be processed into Tenon to control the overall precision of bearing plate orientation tool, the construction of next step operation together with then reinforcing with substructure shuttering, can be carried out.
Compared with prior art the present invention has the following advantages.
1, the present invention utilizes the orientation tool of making, vertical multi beam prestress wire location difficulty in construction is effectively avoided and precision controlling cannot guaranteed problem according to the using method construction drafted, save the overall work cycle of location simultaneously, there is good stability, and effectively ensure that the pre-buried quality of built-in fitting, orientation tool can be reused, and turnover is installed all very simple and convenient, has obvious economic benefit and technology to ensure;
2, simplicity of design of the present invention, orientation tool makes material requested and machining tool and is and on-the-spotly often uses, and processing is simple, and speed of application is fast, be conducive to the control overflow of precision in constructing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is bearing plate orientation tool front schematic view in the present invention;
Fig. 2 is bearing plate orientation tool reverse side schematic diagram in the present invention.
Detailed description of the invention
This device comprises step,
1) formwork erection instrument is made
According to design shape and the size of superstructure bearing plate, be made into 1:1 ratio bearing plate orientation tool with bamboo slab rubber and the lumps of wood, then bearing plate orientation tool is cut into 7 fritters, as shown in Figure 1;
2) bearing plate orientation tool is installed
Based on substructure shuttering and bottom steel strand, on template top by determining that position, control point installs bearing plate orientation tool one by one, utilize the lumps of wood on bearing plate orientation tool to control the overall precision of bearing plate orientation tool, the construction of next step operation together with then reinforcing with substructure shuttering, can be carried out.
Preformed hole diameter on described bearing plate orientation tool is less than position, the hole diameter 1 centimetre on bearing plate; Described bearing plate orientation tool bottom concrete structure vertical prestressing bellows diameter is less than position, the hole diameter 2 centimetres on bearing plate.
Vertical multi beam prestressing force orientation tool, it is the relative position in conjunction with the design size of concrete segment pre-buried steel twisted wire and the preformed hole position of upper end steel work bearing plate, bamboo slab rubber is utilized to make bearing plate orientation tool by steel superstructure bearing plate geomery with the ratio of 1:1 row, effectively control the positioning precision of concrete segment pre-buried steel twisted wire with this bearing plate orientation tool, make it that steel superstructure can be made after concreting completes can to realize accurate installation smoothly.
1, bearing plate orientation tool is made
According to design shape and the size of superstructure bearing plate, bamboo slab rubber and the lumps of wood is utilized to be made into 1:1 ratio bearing plate orientation tool, bearing plate orientation tool makes reserving hole by the basis designing preformed hole position size reducing 1 centimetre, so both can ensure the positioning precision of vertical multi beam prestress wire, also effectively prevent due to the large factor of manual operation error, again bearing plate orientation tool is cut into 7 fritters, be convenient to having bad luck and installing of orientation tool, as shown in Figure 1;
2, bearing plate orientation tool is installed
Based on substructure shuttering and bottom steel strand, on template top by determining that position, control point installs bearing plate orientation tool one by one, the lumps of wood on bearing plate orientation tool is utilized to be processed into Tenon to control the overall precision of orientation tool, the described lumps of wood is arranged on bearing plate orientation tool reverse side, Tenon is processed in connection between the lumps of wood of 1 fritter bearing plate orientation tool reverse side and the lumps of wood of another 1 fritter bearing plate orientation tool reverse side, as shown in Figure 2, then reinforce with substructure shuttering together with can carry out the construction of next step operation.
Strictly must control anchor point in construction and installation process, in the assembled process of 7 fritter, carry out closed sign between block and block, be convenient to assembled putting in place, reduce the impact that assembled error is brought.
