The utility model relates to a construction field specifically is cast-in-place pier construction platform.

Background

The traditional pier construction platform building process is a bracket and transverse and longitudinal beam type bearing bottom die mode, a project with too low pier design standard is aimed at, the welded bracket is seriously affected by damp, if the process is applied to the project, the construction efficiency is too low, manpower and material resources are consumed, and the requirement of an owner on the construction period cannot be met.

SUMMERY OF THE UTILITY MODEL

For solving above problem, the utility model discloses to the operating mode that pier design standard height is too low, provide a cast-in-place pier construction platform of simple and easy design, can improve cast-in-place pier platform and set up the efficiency of construction, practice thrift construction cost by a wide margin.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: cast-in-place pier construction platform, its characterized in that: the cantilever beam structure comprises two cross beams and hook bolts, the cross beams are supporting structures of a construction platform, a whole template and an upper structure, the two cross beams are hung on the steel protective cylinder wall through the hook bolts hung on the top surface of the steel protective cylinder, the tail ends of the hook bolts penetrate through the bottom of the cross beams and are fixed through high-strength nuts, the upper ends of the two hook bolts are welded, and the upper ends of the cross beams are connected with buoys.

The wall thickness of the steel casing is 16mm, and the diameter is 1600 mm.

The hook bolt is diameter 45mm round steel, and the material is 35CrMoA, and with the steel protect between the section of thick bamboo adopt spacing shelves welding reinforcement, adopt two-sided full weld between the hook bolt, welding seam length 300 mm.

The limiting gear is a steel plate with the thickness of 2.5 cm.

The cross beam is a double-spliced I-shaped steel 32b, and the temporary beam supporting frame is an I-shaped steel 12.

The bottom die template is a batten of 10cm x 15 cm.

The utility model relates to a cast-in-place pier construction platform mainly is to the operating mode that pier design standard height is too low, and it is easy to set up the preparation, and is easy and simple to handle, can save a large amount of cost of labor, material cost and time cost.

Drawings

Fig. 1 is a schematic plan view of the present invention;

FIG. 2 is a sectional view taken along line 1-1 of FIG. 1;

in the figure: the device comprises a cross beam 1, a hook bolt 2, a high-strength nut 3, a steel casing 4, a limiting stop 5, a bottom die template 6 and a buoy 7.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to the specific embodiments.

Examples

As shown in fig. 1 and 2, the cast-in-place pier construction platform comprises a cantilever structure and a bottom die template laid on the cantilever, wherein the cantilever structure comprises a cross beam 1 and hook bolts 2, the cross beam 1 is a support structure of the construction platform, the whole template and an upper structure, the cross beams 1 are two and are respectively erected on temporary beam supports, the temporary beam supports are welded on a steel pile casing 4 of a cast-in-place pile, the two cross beams 1 are all hung on the steel pile casing wall through the hook bolts 2 hung on the top surface of the steel pile casing 4, the tail ends of the hook bolts 2 penetrate through the bottom of the cross beam 1 and are fixed through high-strength nuts 3, the upper ends of the two hook bolts 2 are welded, and the upper ends of the cross beams are connected with buoys 7.

The wall thickness of the steel casing 4 is 16mm, and the diameter is 1600 mm.

Couple bolt 2 is diameter 45mm round steel, and the material is 35CrMoA, and with steel protect between the section of thick bamboo 4 adopt spacing shelves 5 to consolidate, adopt two-sided full weld between couple bolt 2, welding seam length 300 mm.

The beam 1 is a double-spliced I-shaped steel 32b, and the temporary beam supporting frame is an I-shaped steel 12.

The bottom die template 6 is a batten of 10cm x 15 cm.

Description of the working principle of the cast-in-place pier construction platform:

the cross beam is used as a supporting structure of a construction platform, the whole template and an upper structure, the temporary bracket is welded by means of a steel casing after construction, and the temporary bracket mainly supports the cross beam temporarily. The cross beam is erected on the temporary bracket, supported through the hook bolt on the wall of the steel pile casing and then reinforced through the high-strength nut, and a cantilever beam structure is formed. The steel protects and welds through spacing shelves between a section of thick bamboo and the couple bolt, prevents to lead to the couple unbalance loading among the concrete placement process, lays die block, welding guardrail on the crossbeam afterwards, and the platform forms, is convenient for dismantle after the construction.

The utility model relates to a cast-in-place pier construction platform mainly crosses lowly to pier design elevation, if adopt the construction process of traditional bracket, horizontal girder formula bearing die block, the welding bracket receives the moist water influence seriously, and the efficiency of construction is too low. The novel cast-in-place pier construction platform is easy to erect and manufacture, simple and convenient to operate, and capable of saving a large amount of labor cost, material cost and time cost.
