Description

Modular, adjustable hollow mound interior operation platform

Technical Field

The utility model belongs to the technical field of operation platform, concretely relates to modular, operation platform in adjustable hollow mound.

Background

With the rapid development of the social economy of China, particularly the deepening of the infrastructure, the traffic cause is rapidly developed. In the mountainous area traffic construction, the bridge engineering construction is relatively complex, the bridge pier columns are relatively high, and most of the high bridge pier columns are designed by hollow piers. The pier body concrete for hollow high-pier construction is vertically transported by adopting a hopper and automatically turned, and the hollow pier inner mold is constructed by adopting an arc plate turning mold, so that a good foundation is laid for the interior and exterior beauty of the pier body concrete. Operation platform in can need be built when hollow high mound inboard construction, operation platform often adopts simple and easy bamboo springboard to build in the tradition, however because the change in hollow mound cross-section, the bamboo springboard of not unidimensional need be changed, builds comparatively trouble, and the security can not obtain the assurance.

Application number CN201920401315.5 discloses a hollow adjustable interior operation platform of variable cross section thin wall, it laminates through first component and second component, fix the screw hole on the first component and the bolt on the second component according to the length that people need afterwards, thereby realize the change of operation platform along with the hollow mound of variable cross section, can continuous adjustment size, any position installation use in variable range, only need join in marriage size operation platform in 1-2 and just can accomplish whole pier shaft construction, can recycle between the different pier stud, need not to change the reworking preparation because of the pier shaft, save just, the labour saving, and is with low costs. Admittedly, the internal operation platform disclosed in the patent can achieve the above technical effects, but it has certain disadvantages: its pier stud concrete includes connecting block and reservation reinforcing bar, and pier stud concrete passes through the connecting block and constitutes fixed knot with the reservation reinforcing bar and construct, and then fixes first platform skeleton and second platform skeleton. It can be obviously seen from the combination of the specification and the attached figure 1 that the connecting block and the reserved steel bars are arranged in the pier body concrete, the arrangement mode is troublesome, the bearing load of the reserved steel bars is limited, and certain potential safety hazards exist. In the hollow pier construction process, have the back rib channel-section steel on the hollow pier centre form, if can utilize the back rib channel-section steel on the hollow pier centre form to provide the support for interior operation platform and can make operation platform's more simple of buildding undoubtedly, safety agrees with actual construction needs more simultaneously.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art that is already known to a person skilled in the art.

Detailed Description

The technical solution of the present invention is described clearly and completely below.

Examples

Referring to fig. 1-5, a modular, adjustable hollow pier internal operating platform, comprising:

the cross arms 100 are horizontally arranged at intervals and paved in the hollow pier, the cross arms 100 are divided into short cross arms 101 and long cross arms 102, and the long cross arms 102 comprise long cross arm bodies 1021 and fastening bolts 1022; the number of the long cross arm bodies 1021 is at least 2, and a plurality of adjusting holes 10211 are uniformly formed in the long cross arm bodies 1021; the fastening bolts 1022 penetrate through the adjusting holes 10211 to fixedly connect the end parts of the adjacent 2 long cross arm bodies 1021;

the access panel 200 is laid on the cross arm 100, the access panel 200 is composed of a plurality of access panel bodies 201, and every two adjacent access panel bodies 201 are fixedly connected through a connecting bolt 202. Here, the strap 200 includes a rectangular frame and a steel plate welded to a rectangular frame portion.

In this embodiment, two ends of the short cross arm 101 and the long cross arm 102 are respectively welded with a limiting plate 103 facing downwards vertically, and in the actual use process, the limiting plates 103 are buckled in the back rib channel steel 301 on the hollow pier inner mold 300, so that the short cross arm 101 and the long cross arm 102 can be limited.

In addition, in this embodiment, short cross arm 101, long cross arm body 1021 are the channel-section steel, and the channel-section steel is more common sheet metal component in the bridge work progress, can select material on the spot.

When the inner operation platform in the embodiment is built, the specific arrangement mode of the short cross arm 101 and the long cross arm 102 is determined according to the cross section in the hollow pier. Referring to the orientation of fig. 1, the length of the upper end and the lower end of the cross section in the hollow pier is shorter, so that the short cross arm 101 is disposed at the 2 positions, and the long cross arm body 102 is disposed at the other positions, when the long cross arm 102 is disposed, the length of the preset position is measured, the fastening bolt 1022 is unscrewed and removed, the 2 long cross arm bodies 1021 are moved to make the length of the long cross arm 102 correspond to the length of the preset position, and then the fastening bolt 1022 penetrates through the adjusting holes 10211 at the mutually close end portions of the 2 long cross arm bodies 1021 to fixedly connect the 2 long cross arm bodies 1021 to form the long cross arm 102.

Then, the short cross arm 101 and the long cross arm 102 are hoisted into the hollow pier by using a crane, and the limit plates 103 at the two ends of the short cross arm 101 and the long cross arm 102 are buckled in the back rib channel steel 301 on the hollow pier inner mold 300. Meanwhile, the area of the butt strap 200 is determined according to the area of the hollow pier at the cross section, a proper number of butt strap bodies 201 are selected, and the butt strap 200 is formed by fixedly connecting a plurality of butt strap bodies 201 through connecting bolts 202; after the short cross arm 101 and the long cross arm 102 are arranged, the access board 200 is lifted into the hollow pier and laid on the cross arm 100 by using a crane, so that the construction of the operating platform in the hollow pier is completed.

When the next hollow pier is subjected to turnover formwork construction, the butt strap 200 and the cross arm 100 are taken out once by using a crane, the length of the cross arm 100 and the size of the butt strap 200 are readjusted according to the inner cross section of the next hollow pier, and then the cross arm 100 and the butt strap 200 are hung in place and recycled until the hollow pier construction is completed.

The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application, to thereby enable others skilled in the art to make and utilize various exemplary embodiments of the invention and various alternatives and modifications.
