Example Embodiment

[0023] Example 1:

[0024] figure 1 The steel tube bundle shear wall selects rectangular and plate steel units to be arranged and connected in sequence, and surrounds them into a hollow steel tube, which includes a first flange 11, a second flange 12, and a web 2, and the web 2 is adjacent steel pipe Divider board. Such as image 3 , The webs of the upper and lower steel pipe bundles are connected by bonding, which includes the bag 3, the middle piece 4, the lower (steel pipe bundle) web 21, and the upper (steel pipe bundle) web 22. The bag includes a closed peripheral side The wall 31 and the bottom plate 32 are containers with the middle cavity 33 opening to the top surface 34; the top surface of the lower web 21 is connected to the bottom surface of the bag, usually by welding, of course, it can also be connected by bolts (the same below); The top surface of 4 is connected with the bottom surface of the upper web 22 (the middle piece 4 can also be an extension of the upper we...

Example Embodiment

[0034] Example 2:

[0035] Such as Figure 4 , U-shaped steel units are arranged in sequence and connected to form a steel tube bundle shear wall. Such as Figure 4 , Figure 5 In the left figure, part of the lower web 21 in this example is used as one side wall 37 of the bag 3, and part of the lower first and second flanges 111 and 121 are used as the two end side walls 38 of the bag 3; the top of the additional side wall 31 is The inclined surface 36 inclined upwards and outwards may also be a curved surface, and plays a role of guiding the intermediate piece 4. Others and Example 1 figure 1 , 3 The instructions are the same.

Example Embodiment

[0036] Example 3:

[0037] In this example, except that the inclined surface 36 is not provided, the arrangement of the bag is the same as that of the second embodiment. If as Figure 4 Grouting holes 5 are provided on the side walls 38 at both ends of the bag 1; and Figure 5 In the right picture, the cover 6 is fixed to the middle piece 4 or the upper surface of the side wall of the bag 1. The middle piece 4 extends into the cavity, and the cover 6 blocks or closes the opening 34 to prevent concrete from entering; Cover 6 adopts spring sheet, which fits well. It can also use other metal sheets or rubber strips, or a combination of spring sheets and rubber strips; then weld the connecting lines 113 and 123; then, pour concrete into the cavity of the steel tube bundle; The grouting hole 5 is filled with structural glue or other adhesives to fill the void under the cavity 33 and the cover 6.

[0038] Because the adhesive is welded first and then the adhesive is poured, general adh...

Abstract

The invention relates to a bond type connector and a bond type steel pipe bundle assembly, and belongs to the field of steel structures. The invention provides two technical schemes: (1) the bond typeconnector comprises a bag, a middle piece, a first connected piece and a second connected piece; the bag comprises a sealed peripheral side wall and a bottom plate, and is a container with a middle cavity opened toward the top surface; the first connected piece is connected with the bag; the middle piece is connected with the second connected piece; and the middle piece stretches into the cavityfrom the opening and is adhered tightly by a filled binder; and (2) the bond type steel pipe bundle assembly comprises an upper steel pipe bundle and a lower steel bundle; more than one steel unit isarranged and connected sequentially so as to enclose to form steel pipes with cavities; the upper steel pipe bundle and the lower steel pipe bundle comprise first flanges, second flanges and web; thewebs are separation plates of the adjacent steel pipes; and the webs of the upper steel pipe bundle and the lower steel pipe bundle are connected by adopting the bond type connector. The bond type connector and the bond type steel pipe bundle assembly provided by the invention are beneficial to saving steel materials, simple in structure, convenient to manufacture, and suitable for connecting thesteel pipe bundles at any position.

Description

technical field [0001] The invention belongs to the field of steel structures in the construction industry, and in particular relates to a steel pipe bundle connection. Background technique [0002] At present, concrete is poured into the steel pipe bundles as shear walls or columns. The steel pipe bundles are prefabricated in the factory, and the upper and lower steel pipe bundles are connected on the construction site. Since the separating webs of adjacent steel pipes are enclosed inside, the site cannot be directly connected by welding or bolts. , usually using the lap connection of inserting steel bars of equal area, it takes about 90d (d is the diameter of the steel bar) to lap the webs of the upper and lower steel tube bundles, which is very wasteful, and the steel bars are thick and dense, which affects the quality of concrete pouring; because concrete The tensile and shear strength of the joint is only about 2Mpa, which cannot reliably transmit the force of the upper...
