Abstract
The utility model relates to a concrete embedded work-piece, in particular relates to a bridge contact net foundation pre-buried bolt distance control correction device, which comprises a steel plate, and is characterized in that the steel plate is at least provided with two rows of five or more bolt steel bushings; both end parts of the steel plate are connected with a hanging ring; the depth that the bolt steel bushing is embedded into the steel plate is half to two thirds of the thickness of the steel plate; then the bolt steel bushing is welded to the steel plate; the inner diameter of the bolt steel bushing and the steel plate form a through hole. The device has the advantages that the structure is simple, the cost is low, the time and the labor power are saved, and the pre-buried precision of the bolt can satisfy the requirements of the designed allowed error. In the construction of a large-sized bridge of a railway passenger transportation special line, the qualification rate of the contact net foundation pre-buried bolt when the control tool is not adopted is only 30 percent, but after the control correction device is adopted, the qualification rate of the contact net foundation pre-buried bolt is 100 percent, and the power is improved by three times or more; the device can be widely used in the concrete construction of the pre-buried bolt in the building and the bridge industries.
Description
Technical field
The utility model relates to concrete embedded engineering, is specifically related to pre-embedded bolt spacing control of a kind of bridge contact net basis and means for correcting.
Background technology
Existing home and abroad all takes much count of for the interface engineering of special line for passenger trains, the quality of interface workmanship, directly determine the quality of special line for passenger trains engineering, the precision allowable error of Passenger dedicated railway Bridge contact net basis pre-embedded bolt only has only ± 1mm, for example the Taiwan high ferro is exactly to postpone operation because the quality of interface engineering causes, and bridge contact net basis is pre-buried to be one of interface engineering.In concrete during pre-embedded bolt, if deviation is arranged slightly, can cause installation period to prolong or do over again, there are human and material resources and waste of time, can say that carcase work should reach the precision of machine-building, as its difficulty of civil engineering construction is very big, does not all have mature technique to use for reference both at home and abroad.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and cost is low, and is time saving and energy saving, and the precision of its pre-embedded bolt can satisfy pre-embedded bolt spacing control of a kind of bridge contact net basis and the means for correcting that the design allowable error requires.
In order to overcome the pre-buried common quality defect in bridge contact net basis that prior art causes, the technical solution of the utility model is to solve like this: comprise a block plate, special character of the present utility model is to be connected with at least on the steel plate bolting steel sleeve of two rows more than three, the steel plate both ends connect handle, described bolting steel sleeve is embedded in the steel plate hole and welds, and its bolting steel sleeve diameter and steel plate hole are connected to through hole.
It is 1/2～2/3 of steel plate thickness that described bolting steel sleeve step embeds the steel plate degree of depth.
The utility model compared with prior art, have simple in structure, cost is low, time saving and energy saving, the precision of its pre-embedded bolt can satisfy the characteristics that the design allowable error requires, in certain special line for passenger trains grand bridge construction, the qualification rate that does not adopt contact net basis pre-embedded bolt before the control tool only 30%, the qualification rate 100% of contact net basis pre-embedded bolt behind the employing control tool, effect improves more than 3 times, extensively is used in the concrete construction of building and bridge industry pre-embedded bolt.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is I-I cross sectional view of Fig. 1;
Fig. 3 is II-II cross sectional view of Fig. 1;
Fig. 4 is steel plate processing plane figure.
The specific embodiment
Accompanying drawing is embodiment of the present utility model.
Below in conjunction with accompanying drawing summary of the invention is described further:
Referring to figs. 1 through shown in Figure 3, pre-embedded bolt spacing control of a kind of bridge contact net basis and means for correcting, comprise a block plate 1, at least be connected with the bolting steel sleeve 2 of two rows more than three on its steel plate 1, steel plate 1 both ends connect handle 3, described bolting steel sleeve 2 is embedded in steel plate 1 mesopore and welds, and it is 1/2～2/3 of steel plate thickness that bolting steel sleeve step embeds the steel plate degree of depth, and its bolting steel sleeve 2 internal diameters and steel plate 1 hole are connected to through hole.
Shown in Figure 4, at first on steel plate 1, bore the hole that needs pre-embedded bolt quantity by designing requirement, be drilled with two rows in the accompanying drawing 4 of the present utility model and amount to 10 holes.Each hole washes out and the corresponding hole with the level of the diameter of pre-embedded bolt by numerically controlled lathe, and the diameter in its hole and the diameter of pre-embedded bolt can carry out tight fit and get final product.
In sum, the new using method of this practicality is summarized as follows:
1, determines the quantity and the position of bridge engineering contact net basis built-in fitting;
2, will need pre-buried bolt to be inserted in the sleeve 2 of this device;
3, weld on the pre-embedded steel slab of design according to pre-buried bolt one end that is inserted in the sleeve 2,, after welding is finished, manually device is promoted out by handle 3 with the pre-buried bolt position of sleeve 2 controls;
4, will weld good pre-embedded bolt and be placed into bridge design embedded foundation position, with the accurate setting-out of total powerstation, correction.The reinforcing bar welding is fixed in the pre-embedded bolt of the positive good position of high-ranking officers and the bridge, then branching standing template, fluid concrete.Because in the process of fluid concrete, concrete needs vibration, might change the exact position of position, pre-embedded bolt hole, this moment is not when concrete also reaches setting and hardening, again this device is nested in the pre-embedded bolt, until treating that concrete reaches setting and hardening, after having certain intensity, lifting device for the second time, at this moment installing relative pre-embedded bolt has been a hole bit correction effect, by twice lifting of this device, thereby has guaranteed the accurate location of pre-embedded bolt, and accelerated construction speed, workmanship also adheres to specification.
