Description

Technical Field

[0001] The utility model relates to the field of multi-story suspended structure buildings, in particular to an assembled installation adjustment device. Background Art

[0002] Steel tie rods have the advantages of strong bearing capacity, high safety, and convenient and quick use, which makes them widely used in some large-span cantilever and complex structure construction projects. Traditional steel tie rods are installed by connecting ear plates. If the diameter of the steel tie rod is large, the thickness of the connecting ear plate is also large, which brings great difficulties to node design, material procurement, processing and installation. In addition, when the steel tie rod is connected to the steel beam, the ear plate is exposed, and the exposed ear plate will be hit or corroded, affecting the safety and aesthetics of the structure.

[0003] In the prior art, there is a connection node 300 in which each steel tie rod is connected by a sleeve-type connector and supports the floor steel beam, which can avoid the appearance of thick plates, hide the connection node at the floor, and improve the safety and aesthetics of the structure. For example, a steel tie rod connection node disclosed in Chinese patent application number 202222778363.0 supports the steel beam and connects each tie rod through a steel sleeve, a locking device and a steel pad. However, during the high-altitude installation process of this connection node, it needs to be adjustable up and down to ensure the accuracy of the installation elevation of the finished steel tie rod connection assembly, and during the process, it is necessary to ensure that the steel tie rod is pulled and stressed evenly during construction to avoid damage to the steel tie rod body.

[0004] Therefore, in order to meet the installation requirements of the above-mentioned connection structure, a device and method that can assist in adjusting the height thereof is now needed. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Some embodiments of the present application provide an assembled installation adjustment device for temporarily supporting a multi-story suspended structure, the multi-story suspended structure comprising: an upper steel tie rod 101 and a lower steel tie rod 102 connected by a connecting node 300, and a floor steel beam 200 supported by the connecting node 300, the assembled adjustment device comprising: a hanging beam 1 hung on the steel beam, a supporting beam 2, a connecting rod 3 connecting the hanging beam 1 and the supporting beam 2 at an adjustable relative distance, and a supporting and limiting member 5 arranged on the supporting beam 2, supporting the connecting node 300 and radially limiting the lower steel tie rod 102.

[0027] The installation process of existing multi-story suspended structures often requires the assistance of lifting equipment, and the accuracy of adjusting the installation height is low. The assembled installation adjustment device of the present application is hung on the floor steel beam 200 through the hanging beam 1, and can bear the weight with the help of the floor steel beam 200 and form a support for the connection node 300 through the supporting beam 2 and the supporting limiter 5, and adjust the height of the connection node 300 with the support force of the floor steel beam 200. The present application uses the connecting rod 3 to bear tension, and uses the connection node 300 to bear part of the pressure without compressing the steel tie rod, which meets the design and use occasions of the steel tie rod and is not easy to cause damage to the steel tie rod. The supporting limiter 5 also forms a radial limit on the lower section steel tie rod 102 to prevent the lower section steel tie rod 102 from shaking during height adjustment, causing the connection to become unstable.

[0028] Considering that the connection node 300 is usually arranged in a ring shape, in order to fully support the connection node 300, the support limiter 5 should be in full contact with the connection node 300, so it has a certain contact area. In some embodiments, the assembled installation adjustment device also includes a secondary support beam 4 arranged perpendicularly to the support beam 2, and the support beam 2 and the secondary support beam 4 jointly support the support limiter 5 to support the support limiter 5 in multiple directions. For example, the secondary support beam 4 is arranged perpendicularly to the support beam 2 and is connected to the support beam 2 by high-strength bolts.

[0029] The supporting limiter 5 needs to limit the lower steel tie rod 102 in the circumferential direction, so it needs to have a limiter that matches the shape of the steel tie rod. Considering the convenience of installing the supporting limiter 5, in some embodiments, the supporting limiter 5 includes two detachable limit blocks that are surrounded by a ring, and the inner side wall of the ring limits the steel tie rod. Setting the supporting limiter 5 in this way can avoid inserting the supporting limiter 5 from the lower steel tie rod 102, and can be assembled and installed from the side of the lower steel tie rod 102.

[0030] The support and limit member 5 needs to be under pressure. In some embodiments, the limit block includes an upper side plate 51 , a lower side plate 52 , and a stiffening rib 54 disposed between the upper side plate 51 and the lower side plate 52 to enhance the pressure-bearing capacity of the support and limit member 5 .

[0031] In some embodiments, the connecting rod 3 is a screw threadedly connected to the hanging beam 1 and the supporting beam 2. Using the screw as the connecting rod 3 to connect the hanging beam 1 and the floor steel beam 200 can achieve a relatively stable adjustable connection and is easy to implement.

[0032] The present application can also be used to assist in adjusting the relative position of the connection node 300 and the upper steel tie rod 101 .

[0033] In some embodiments, as an existing multi-story suspension structure, the connection node 300 is threadedly connected to the upper steel tie rod 101 and the lower steel tie rod 102, and the relative position can be adjusted by the threaded connection. The adjustment device of the present application acts on this kind of multi-story suspension structure. After supporting the connection node 300 upward, it is also relatively easy to adjust the relative position between the upper steel tie rod 101 and the connection node 300 through the threaded connection. In the process of adjusting the relative position of the connection node 300 and the upper steel tie rod 101, the relative position of the connection node 300 and the supporting limiter 5 will inevitably change, affecting the supporting effect. The connection rod 3 can adjustably connect the hanging beam 1 and the supporting beam 2 to make the supporting effect of the connection node 300 of the present application adjustable. When adjusting the relative position of the connection node 300 and the upper steel tie rod 101, the relative position of the hanging beam 1 and the supporting beam 2 can be adjusted accordingly to control the supporting force of the connection node 300 to be within a range suitable for construction.

[0034] In order to increase the contact area between the connecting rod 3 and the hanging beam 1 , in some embodiments, a first pad 31 is provided on the hanging beam 1 , and the connecting rod 3 is connected to the first pad 31 to avoid stress concentration on the hanging beam 1 and damage to the hanging beam 1 .

[0035] In order to increase the contact area between the connecting rod 3 and the supporting beam 2, in some embodiments, a second pad 32 is provided on the supporting beam 2, and the connecting rod 3 is connected to the second pad 32 to avoid stress concentration on the supporting beam 2 and damage to the supporting beam 2.

[0036] In some embodiments, the hanging beam 1 and the supporting beam 2 are made of channel steel. Channel steel is light in weight and suitable for shearing, and is more suitable for serving as the hanging beam 1 and the supporting beam 2 of the present application.

[0037] Some embodiments of the present application also provide a method for adjusting the height of a multi-story suspended structure, using the above-mentioned steel tie rod assembly adjustment device to temporarily support the connection node 300 to adjust the multi-story suspended structure to its designed elevation, so as to construct the multi-story suspended structure more stably and accurately.

[0038] Some embodiments of the present application include a steel tie rod connection node 300, which is used to connect two steel tie rods in a multi-story suspension structure and support a floor steel beam 200, including: a connecting sleeve 301 provided with a first internal thread and an external thread, a supporting sleeve 302 provided with a second internal thread 21 threadedly connected to the external thread, and a ring plate 303 fixedly arranged on the outside of the supporting sleeve 302 for supporting the floor steel beam 200; two steel tie rods are threadedly connected to both ends of the first internal thread.

[0039] The internal thread of the connecting sleeve 301 connects the two steel tie rods. The connecting sleeve 301 only bears tension, and the force transmission between it and the steel tie rod is uniform and not easy to be damaged. The present application is also provided with a supporting sleeve 302 threadedly connected to the outside of the connecting sleeve 301. Compared with the traditional connection node, the threaded connection can make the construction operation of the supporting sleeve 302 easier when adjusting the elevation, and the force on the upper and lower tie rods is more uniform during adjustment, which will not cause stress concentration and damage to the steel tie rod and the supporting sleeve 302. The ring plate 303 is used to increase the contact area between the connection node and the floor steel beam 200, so that the support is more reliable.

[0040] In some embodiments, a gasket 304 is provided between the ring plate 303 and the floor steel beam 200 to make the force transmitted from the floor steel chain to the steel tie rod more uniform. Typically, the gasket 304 is a rubber pad.

[0041] In some embodiments, a supporting rib 305 for supporting the ring plate 303 is provided between the ring plate 303 and the supporting sleeve 302, so that the force of the ring plate 303 supporting the floor steel beam 200 can be more evenly transmitted to the supporting sleeve 302. Preferably, the supporting rib 305, the supporting sleeve 302 and the ring plate 303 are welded. Preferably, 4-8 supporting ribs 305 are evenly arranged along the circumference of the ring plate 303. The thickness of the supporting rib 305 is calculated and designed based on factors such as the diameter of the steel tie rod and the load of the floor steel beam 200. Empirically, its thickness is 40-80 mm.

[0042] In some embodiments, the supporting sleeve 302 and the ring plate 303 are connected by welding. The connection between the supporting sleeve 302 and the ring plate 303 needs to withstand greater stress. Welding has higher connection strength and is more convenient to construct, which can meet the implementation requirements of this application.

[0043] The design parameters of the ring plate 303 are calculated and designed based on factors such as the diameter of the steel tie rod and the load of the floor steel beam 200. Empirically, the outer diameter of the ring plate 303 is at least 200 mm larger than the outer diameter of the connecting sleeve 301, and the thickness of the ring plate 303 is 20-60 mm.

[0044] In some embodiments, locking members 11 for locking and fixing the steel rods are provided at both ends of the connecting sleeve 301. The locking members 11 are used to further lock and fix the relative positions of the two steel rods in combination with the threaded connection. The locking members 11 can be set as locking nuts.

[0045] In some embodiments, the floor steel beam 200 is an I-shaped structure, including an upper plate, a web plate, and a lower plate 201, and the upper end of the connecting sleeve 301 is higher than the lower plate 201. The connecting sleeve 301 used for threaded connection of two steel tie rods usually has a relatively long length because it must have a threaded section of a certain length. Setting the upper end of the connecting sleeve 301 higher than the lower plate 201 allows the connecting sleeve 301 to be partially accommodated in the floor steel beam 200, thereby increasing the aesthetics and sealing performance.

[0046] In some embodiments, a floor slab 300 is cast above the floor steel beam 200, and a seal 306 is provided between the floor slab 300 and the steel tie rod to prevent the steel tie rod from being corroded or damaged. The seal 306 is usually a rubber cover.
