Abstract
The invention discloses a tower crane foundation arrangement method applied on a great bridge. The tower crane foundation arrangement method is characterized by comprising the following steps that after concrete pouring of lower tower columns is completed, built-in fittings used for installing a tower crane are arranged on the top faces of the lower tower columns; steel bars and formworks are installed on the top faces of the lower tower columns, and concrete pouring of upper tower columns is completed; the built-in fittings located on the top faces of the lower tower columns are sprung out to be used for connecting foundation components of the tower crane, and then installation of the tower crane is completed on the foundation components. The tower crane foundation arrangement method has the advantages that the construction method is simple and convenient, operation is easy, and the construction cost can be effectively lowered.
Description
Technical field
The invention belongs to technical field of bridge engineering, be specifically related to a kind of tower crane method to set up be applied on bridge.
Background technology
For the setting of tower crane, extremely common in Bridges in Our Country is built.Especially be the problem of solution vertical transport in large bridge is built, tower crane be often set and solve this problem.But the basis of its tower crane generally all can be arranged on cushion cap foundation, so relatively more directly perceived, stressed also clearer and more definite.
But, cushion cap foundation arranges tower crane, generally may run into following problem:
1) when cushion cap area meet tower crane is set time, the side root meeting of tower crane " falls through ", at this moment, can solve with the interim bracket of encorbelmenting on suspended deck structure limit; Or the interim pile foundation of injection processes;
2) when lower king-post strut is higher, for solving the column stabilizing measures of tower crane, sometimes temporary rod system is set between lower king-post strut and tower crane pier shaft.Namely built-in fitting to be set between concrete column, adverse influence is brought to the presentation quality of concrete column;
3) when bridge floor design is comparatively wide, original structure design can be generally " vase " style column superstructure design, to meet the stable needs of cross-section of bridge; Like this, certain difficulty is brought to the setting of tower crane.
Therefore, be not very high structure to superstructure, need tower crane to solve the problem of vertical transport simultaneously, under the precondition ensured safety, high-quality, realize job site Perpendicular Problems fast, economically, become the problem that construction technical staff needs to solve.
Summary of the invention
The object of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of tower crane method to set up be applied on bridge is provided, this tower crane method to set up, by by the end face of the basis instrument of tower crane in lower king-post strut, decreases the sections of tower crane tower body, reduces operating expenses.
The object of the invention realizes being completed by following technical scheme:
Be applied to the tower crane method to set up on bridge, it is characterized in that described tower crane method to set up comprises the steps: after the concrete placings of lower king-post strut, the end face of described lower king-post strut arranges the built-in fitting for installing tower crane; The end face of described lower king-post strut is installed reinforcing bar and template and completes the concrete placings of upper king-post strut; By the built-in fitting being positioned at described lower king-post strut end face ejecting the basic component being used for connecting described tower crane, on described basic component, complete the installation of described tower crane afterwards.
Described lower king-post strut is made up of to the limit binder arranged and middle binder the column vertically arranged and level, and described tower crane supporting is installed on described limit binder and described middle binder.
Described basic component is by welding iron plate to form interim location.
Advantage of the present invention is, (1) solve tower crane be arranged on cushion cap concrete basis or encorbelment on cushion cap foundation " bracket " structure time performance difficulty problem, economical and practical; (2) solving tower crane because of cushion cap area is arranged not, and uses interim injection pile foundation to arrange the operation at sea of tower crane, is conducive to reducing construction cost by reducing operation at sea; (3) because tower crane is arranged on the top of concrete column, decrease the sections of tower crane tower body, the tower body namely within the scope of stem height, because the position arranged is improved, decrease the tower body structure of this section, reduce the lease expenses of equipment.
Accompanying drawing explanation
Fig. 1 is 1/2 lower king-post strut top floor map in the present invention;
Fig. 2 is the positive elevational schematic view of 1/2 lower king-post strut in the present invention.
Detailed description of the invention
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
Be respectively as marked 1-6 in Fig. 1-2, figure: column 1, limit binder 2, middle binder 3, built-in fitting 4, tower crane 5, lateral and diagonal brace 6.
Embodiment: as shown in Figure 1, 2, the present embodiment is specifically related to a kind of tower crane method to set up be applied on bridge, this bridge is the short tower girder stayed-cable bridge of six tower single cable plane, full-bridge has 6 king-towers, each king-tower substructure tower body height is 21-25M, symmetrical between two, king-post top is made up of 2 road binders.
This tower crane method to set up by by the basis instrument of tower crane in the end face of lower king-post strut to simplify construction method, and reduce construction cost, specifically comprise the steps:
(1) complete the concrete placings of lower king-post strut, lower king-post strut is made up of column 1, limit binder 2 and middle binder 3, and twice limit binder 2 is symmetricly set in middle binder 3 both sides, and three's horizontal cross is connected between twice vertical upright column 1; The reinforcing bar and template of building needed for upper king-post strut are installed at lower king-post strut end face; On limit binder 2 with middle binder 3, arrange built-in fitting 4 respectively afterwards, built-in fitting 4 is specially welding and is embedded in iron plate on limit binder 2 and middle binder 3 side in advance;
It should be noted that, these built-in fittings 4 some carry out welding or prefabricated in factory or concentrated processing place, when installing at the scene, will not weld with all kinds of reinforcing bars in column 1, limit binder 2 and middle binder 3, to avoid the intensity affecting lower king-post strut agent structure;
(2) complete the concrete placings construction of upper king-post strut, the intensity of upper king-post strut and modulus of elasticity must reach the requirement of concrete structure design;
(3) on the built-in fitting 4 preset before, eject the basic component for connecting tower crane, i.e. lateral and diagonal brace 6, and utilize iron plate to carry out temporary weld location;
(4) design drawing of foundation tower crane 5 completes the erecting and welding of tower crane 5;
(5) according to the administrative provisions of special equipment, carry out situ loading, and submit a report asking for relevant department and carry out an acceptance inspection.
The present embodiment has safe and reliable, convenient, economical and practical feature of constructing, and specifically comprises following beneficial effect:
(1) solve tower crane be arranged on cushion cap concrete basis or encorbelment on cushion cap foundation " bracket " structure time performance difficulty problem, economical and practical;
(2) solving tower crane because of cushion cap area is arranged not, and uses interim injection pile foundation to arrange the operation at sea of tower crane, is conducive to reducing construction cost by reducing operation at sea;
(3) because tower crane is arranged on the top of concrete column, decrease the sections of tower crane tower body, the tower body namely within the scope of stem height, because the position arranged is improved, decrease the tower body structure of this section, reduce the lease expenses of equipment.
