Utilize structural joint advancing equipment pipe trench device
Technical field
the present invention relates to design of building structures field, especially a kind of device that utilizes structural joint advancing equipment pipe trench.
Background technology
the long floor structure of some hundreds of rice occurred along with the increase day by day of the building scale of construction.From the building use angle, hope that structure do not establish seam as far as possible, but super-long structural because of can producing bigger plane stress, factors such as variations in temperature, concrete contraction causes that beam slab ftractures.Structure design is a basic principle to establish seam less at present, and existing the plan through utilizing structure to establish the seam position is provided with recessed junction plate, advancing equipment pipe trench or bye wash.
Summary of the invention
the present invention seeks to: a kind of device that utilizes structural joint advancing equipment pipe trench is provided.
technical scheme of the present invention is: a kind of structural joint advancing equipment pipe trench device that utilizes; Comprise main structure, the slit between the main structure forms pipe trench, it is characterized in that; Joint bar is reserved in the main structure bottom; Hang the concrete plate down through second pouring and form lower plate and side plate, said lower plate and side plate are formed recessed junction plate, and recessed junction plate is positioned at the main structure below and is connected in main structure.
are further, are provided with prefabricated cover plate on the pipe trench top, stay the wide sum of the seam of establishing to be not less than the structural joint width of traditional handicraft between said prefabricated cover plate and the main structure.
are further, and the recessed degree of depth in said recessed junction plate Autonomous Structure lower end is more than or equal to 200mm.
are further, and said main structure one-time-concreting is accomplished.
Advantage of the present invention is:
1. utilize structure to establish the seam position recessed junction plate is set, but the advancing equipment pipe trench is walked pipeline, also can be used as the bye wash central drainage of floor structure;
Prefabricated cover plate is 2. arranged in
, is convenient to the inspection and maintenance of pipeline.
Control watering of recessed junction plate and smash off-period, can solve the concrete shrinkage stress of super-long structural;
4. because junction plate is recessed, have certain angular deformation ability, can discharge the thermal stresses that difference variation causes, also do not influence the horizontal distortion and the structure stress of each piecemeal main structure self.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 utilizes structural joint advancing equipment pipe trench apparatus structure sketch map for the present invention.
wherein: 1, main structure, 2, recessed junction plate, 3, prefabricated cover plate, 4, pipe trench, 21, lower plate, 22, side plate.
The specific embodiment
Embodiment:
further specify such scheme below in conjunction with specific embodiment.Should be understood that these embodiment are used to the present invention is described and are not limited to limit scope of the present invention.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
technical scheme of the present invention is: a kind of structural joint advancing equipment pipe trench device that utilizes; Comprise main structure 1; Slit between the main structure 1 forms pipe trench 4, and joint bar is reserved in main structure 1 bottom, hangs the concrete plate down through second pouring and forms lower plate 21 and side plate 22; Said lower plate 21 and side plate 22 are formed recessed junction plate 2, and recessed junction plate 2 is positioned at main structure 1 below and is connected in main structure 1.
In
preferred embodiment of the present invention, be provided with prefabricated cover plate 3, stay the wide sum of the seam of establishing to be not less than the structural joint width of traditional handicraft between said prefabricated cover plate 3 and the main structure 1 on pipe trench 4 tops.
In
preferred embodiment of the present invention, the recessed degree of depth in said recessed junction plate 2 Autonomous Structure 1 lower end is more than or equal to 200mm.
In
preferred embodiment of the present invention, said main structure 1 one-time-concreting is accomplished.
above to be shown and has described basic principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the manual just explains principle of the present invention; The present invention also has various changes and modifications under the prerequisite that does not break away from spirit and scope of the invention, and these variations and improvement all fall in the scope of the invention that requires protection.
