Abstract

The utility model provides a bracket for constructing a high pier capping beam. The bracket has the key improvement that the bracket comprises two trusses which are symmetrically arranged at the two sides of a pier body, wherein a plurality of tie bars are penetrated between two counter pulling plates which are arranged at the top of the trusses; and the vertical section of each truss is in the shape of right angled triangle, the cross section of each truss is in the shape of rectangle, and one end of a lower chord rod of each truss which corresponds to the pier body is fixedly provided with a corbel. The bracket has the advantages that the corbels which are arranged at the ends of the lower chord rods of the trusses are inserted into a plurality of holes which are remained on the pier body and are specially treated, the tie bars which are penetrated between the two counter pulling plates arranged at the top of the trusses are used for fixing the trusses at the top of the high pier, and the top surfaces of the trusses can be directly erected with a capping beam constructing template and can be cast with capping beam concrete, thereby eliminating the working procedures of treating the foundation and testing the pressure and the like when constructing with a full framing method, and effectively improving the construction efficiency, and a mass of revolving materials does not need to be rented since the full framing constructing method is not used, thereby being capable of reducing the construction cost of the engineering to a certain degree.

Description

A kind of carriage that is used for high pier capping beam construction

Technical field

The utility model has related to the auxiliary equipment in a kind of high pier capping beam construction, particularly a kind of carriage that is used for high pier capping beam construction.

Background technology

In recent years, along with the high speed development of Chinese national economy, high-grade highway construction presents the situation of advancing by leaps and bounds, to mountain area, marine site development.Mountainous area highway passes through the valley, the bridge pier column height, and material, equipment transportation difficulty, seeking technical constructure scheme safe and reliable, with low cost economically is the problem that the mountainous area highway high pier is built.The highway bridge substructure is a lot of to adopt single many cylinder piers to add the bent cap pattern, adopts the construction of full framing method usually, need conscientiously handle the support ground before setting up the bent cap cast-in-place support, prevents that ground from producing excessive settlement influence bent cap concrete quality and linear.But to tall pier and thin wall, adopt the construction of full framing method, the timbering material consumption is big, and it is many to set up the time spent, and deformation allowance is wayward, need adopt other working measures when meeting river embankment, and efficiency of construction is low, and the waste of turnover material is bigger.

The utility model content

The utility model provides a kind of can improve high pier capping beam efficiency of construction, reduces the carriage that is used for high pier capping beam construction of turnover material use amount.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of carriage that is used for the construction of high pier capping beam, its key improvements is: comprise the truss that is symmetrically set in the pier shaft both sides, truss top, both sides be provided with to wearing lacing wire between the arm-tie; The longitudinal section of described truss is a right-angled triangle, and the cross section is a rectangle, and an end of the corresponding pier shaft of the lower chord of truss is installed with bracket.

Adopt the beneficial effect that technique scheme produced to be: the bracket that truss lower chord end is provided with inserts in the process hole of reserving on the pier shaft of specially treated, what truss top, both sides was provided with is fixed on the Gao Dun top to the multiply lacing wire is set between the arm-tie with truss, directly can on the truss end face, install the bent cap construction formwork then and build the bent cap concrete, operations such as ground processing when removing the construction of use full framing method from and pressure testing, effectively improve efficiency of construction, more in addition, do not use full framing, just need not lease a large amount of turnover material, so, can reduce the engineering construction cost to a certain extent.

Further the utility model is described in detail below in conjunction with accompanying drawing.

The specific embodiment

For making above-mentioned purpose of the present utility model, feature and beneficial effect can become apparent more, below in conjunction with the drawings and specific embodiments among the utility model embodiment, the technical scheme among the utility model embodiment are clearly and completely described.

As Fig. 2, Fig. 3, a kind of carriage that is used for high pier capping beam construction shown in Figure 4, it is characterized in that: comprise the truss 2 that is symmetrically set in pier shaft 1 both sides, both sides truss 2 tops be provided with to wearing lacing wire 3 between the arm-tie 2-3; The longitudinal section of described truss 2 is a right-angled triangle, and the cross section is a rectangle, and an end of the corresponding pier shaft of the lower chord of truss 2 is installed with bracket 2-7.

Described truss comprises wind up layer, stern layer and lower edge layer, the described layer that winds up is rectangular frame, the lower edge layer comprises two lower chord 2-5 and the connecting rod that is connected lower chord 2-5, and described stern layer comprises connection upper chord 2-1 and the vertical support bar 2-4 of lower chord 2-5 and the web member 2-2 at diagonal member 2-6 and middle part.Upper chord 2-1 wherein and lower chord 2-5 adopt i iron, vertical support bar 2-4 and diagonal member 2-6 adopt channel-section steel, web member 2-2 and other connecting rods adopt angle steel, bracket 2-7 adopts the channel-section steel make-up to be welded into box, bracket 2-7 is welded on the lower chord end, and the concrete size of rod member can design according to the practice of construction situation, also can unconventional type design, use the reduction engineering cost to realize turnover.

In concrete application process, at first, reserve square hole in predetermined pier shaft position in the time of pier construction, concrete around the square hole adopts steel mesh reinforcement to strengthen, and hole lining steel plate, steel plate can be welded on the pier shaft cage of reinforcement, when treating that the pier shaft concrete strength reaches designing requirement, respectively the both sides truss is lifted the pier shaft correspondence position with crane, bracket penetrates in the preformed hole on the corresponding pier shaft, wear lacing wire simultaneously, on the truss end face, install the bent cap template then, and build the bent cap concrete according to designing requirement, at last, treat that the bent cap concrete strength reaches designing requirement, i.e. collapsible die, the process of form removal is opposite with installation process.The carriage that the related high pier capping beam of the utility model uses in constructing is not only applicable to the construction of the high pier capping beam of geological condition complex area, can be applied in general bent cap construction and the construction of railway operation line yet, can effectively improve efficiency of construction.
