Description

Directional sliding support connecting structure

Technical Field

The utility model belongs to the field of steel structure design and construction, and particularly relates to a connecting structure of a directional sliding support.

Background

Factories which use bulk materials as raw materials or finished products generally have a large number of dust-carrying devices or buildings, and a large amount of dust is generated during production operation. In order to protect the environment and reduce the emission of harmful particles, dust-carrying equipment or buildings of newly-built factories at present generally adopt a profiled steel sheet wall sealing mode to treat the problem of dust emission; in the prior art, dust-carrying equipment or buildings of the established factories are mostly placed in open air or are subjected to open treatment, and then the dust-carrying equipment or the buildings are required to be subjected to wall sealing post-treatment by adopting profiled steel sheets.

In factories, a maintenance structure is arranged on a building, and particularly, the post-treatment maintenance structure has the difficulty that the connection form of the wall sealing wind-resistant column and the upper main structure is adopted in order not to influence the stress performance of the upper main structure. If the wind-resistant column is directly welded with the upper main body structure, a stress supporting point is added to the upper main body structure, so that the stress form of the main body structure is changed. Meanwhile, when the air temperature changes, the wind-resistant column is influenced by the expansion and contraction effect, and the wind-resistant column can also transmit an upward or downward additional force to the upper main body structure to force the main body structure to displace upward or downward, so that the main body structure is in an unfavorable stress state.

As shown in fig. 1, a generally conventional solution is that a circular hole is formed in the center of a top web 102 of a wind-resistant column 10 (mostly H-shaped steel), the diameter of the circular hole is slightly larger than the size of a bolt, a welded joint plate 101 is additionally arranged at the bottom of an upper main structural member 9, and a rectangular hole with a width slightly larger than the size of the bolt and a certain length (the length is determined according to the vertical deflection deformation f of the main structural member at the top of the wind-resistant column) is formed on the joint plate 101. When the wind-resistant sliding joint is installed, the joint plate 101 is aligned with the center of the hole on the wind-resistant column web 102, and a bolt 103 is arranged in the hole to form a directional sliding joint which only restrains the horizontal displacement of the structure but not the vertical displacement, and the following problems exist in the structure although the structure is simple:

1. the universality is not strong. For the wind-resistant columns with different section types, the sliding support needs to be independently designed, the longitudinal dimension of the sliding long hole needs to be independently designed, and the factors such as large bearing capacity and rigidity difference of the two main shafts in the horizontal direction cause large sliding support structure difference of different use positions, so that standardized manufacturing is not suitable.

2. The structure construction is difficult, and the bolting requires very high manufacturing and installation precision. The center of the orifice must be aligned when the gusset plate is installed, the bolt needs to be accurately positioned to finish the installation of the sliding support, otherwise, the effect of sliding connection is difficult to achieve in the later stage, once the orifice is not aligned during the installation, the bolt cannot be arranged, the sliding support cannot be accurately installed, and the fault tolerance of construction installation is poor.

3. The structure has potential safety hazard. In order to ensure the stress performance of the structure, the nodes adopt sliding supports connected by bolts, and the fastening degree of the bolts directly influences the up-and-down sliding effect of the wind-resistant column. Meanwhile, during production, under the long-term effect of environmental factors, rust is easy to occur at the connecting node of the wind-resistant column, if rust removal and repair cannot be timely carried out, the connecting bolt is extremely easy to be locked due to rust, the wind-resistant column slides up and down to be restrained, the wind-resistant column is caused to change phase to become a supporting column of a top main body structure, the stress form of the top structure is changed, and the wind-resistant column is also likely to yield due to the fact that the vertical pressure transmitted by the upper structure cannot be born.

Through setting up the directional sliding support of steel pipe preparation, have following advantage:

1. the connection mode between the components and the mechanical property of the main body structure are not changed. The steel pipe is connected between the wind-resistant column and the main body structure as a vertically slidable member, so that the horizontal displacement of the wind-resistant column is limited. When the main body structure connected with the upper part generates vertical displacement, the top end of the wind-resistant column moves up and down at the corresponding position of the steel pipe, and the generated displacement and force cannot be transmitted to the upper main body structure member.

2. The directional sliding support has good universality. In practical engineering application, the length and the section of the sliding steel pipe can be designed by taking the maximum vertical deflection and the maximum horizontal shearing force of one project or one building main body structural member as the basis to manufacture the standardized general sliding support. The universal support can be used for connecting wind-resistant columns of any section type at any position.

3. The fault tolerance rate is high, and the construction is convenient. The method has strong adaptability to the main structure to be constructed, and has relatively low construction precision requirement on the main structure. During construction, the sliding support manufactured by the steel pipe is welded on the main structural member, the free expansion and contraction of the sliding part and the small-range movement of the support position do not affect the stress and the usability of the structure, and the fault tolerance of construction is reserved for easy adjustment and convenient construction.

4. The safety is high during the use. The periphery of the sliding steel pipe in the directional sliding support system is wrapped with a 2mm Teflon sheet, the friction coefficient of a sliding area is small, and the support mechanism is easy to slide up and down; meanwhile, the whole support system is a closed system in structure and is less influenced by environmental corrosion, so that the sliding support is not easy to be corroded to lock, and the mechanical property of the sliding support is ensured.

Various combinations will be apparent to those skilled in the art from a review of the present disclosure, and are not intended to be exhaustive or to limit the utility model to the precise forms disclosed.
