Description

Technical Field

[0001] This utility model relates to the field of building structures, specifically to an adjustable connection node structure. Background Technology

[0002] Type C material yards are generally enclosed by large-span truss structures. When truss structures are used, their longitudinal stiffness is relatively weak, and the main structure is subjected to large forces at mid-span, which affects the steel consumption of the structure.

[0003] At the top of the C-shaped material yard, there will be a long platform running longitudinally along the yard. If conditions permit, truss columns can be installed on site to support the main structure. These columns mainly bear vertical pressure and pull force, which greatly improves the mid-span stress of the main structure. At the same time, the support between the columns can effectively improve the longitudinal stability of the main structure.

[0004] However, due to the large load on the C-type material yard, the platform will settle down year by year under the load, which will cause forced displacement of the upper steel structure and have an adverse effect on the structure.

[0005] Therefore, to solve the above problems, an adjustable connection node structure is needed that can adjust the height of the column after the platform settles, thereby releasing forced displacement and improving the effectiveness and service life of the column support. Utility Model Content

[0006] In view of this, the purpose of this utility model is to overcome the defects in the prior art and provide an adjustable connection node structure that can adjust the height of the column after the platform settles, thereby releasing forced displacement and improving the support effectiveness and service life of the column.

[0007] The adjustable connection node structure of this utility model includes a column and a support. The column is detachably assembled on the support, and a height-adjustable support layer is provided between the column and the support.

[0008] Furthermore, the support is provided with a first shear-resistant member and a second shear-resistant member to clamp the column.

[0009] Furthermore, a functional gap is reserved between the first shear member and the column and / or between the second shear member and the column, and a padding layer is provided in the functional gap.

[0010] Furthermore, it also includes a fastening assembly, which includes a connector and a fastener. A base plate is provided on the column, the connector passes through the base plate and connects to the support, the fastener is detachably provided on the connector, and the base plate is limited to the support by the fastener, or can be released from the support.

[0011] Furthermore, the base plate has a first force-bearing end near the first shear member and a second force-bearing end near the second shear member, with the first and second shear members respectively abutting against the first and second force-bearing ends to clamp the column.

[0012] Furthermore, the height of both the first shear-resistant member and the second shear-resistant member exceeds the installation height of the base plate on the support.

[0013] Furthermore, the root of the connector is pre-embedded in the support, and the head of the connector passes through the base plate and is used to cooperate with the fastener to detachably limit the base plate to the support.

[0014] Furthermore, the circumferential dimension of the base plate exceeds the circumferential dimension of the column, and the column is located at the center of the base plate; the fastening assembly includes several groups evenly distributed around the circumference of the column.

[0015] Furthermore, stiffening ribs are provided between the base plate and the column.

[0016] Furthermore, settlement observation points are installed on the column.

[0017] The beneficial effects of this utility model are as follows: The adjustable connection node structure disclosed in this utility model stabilizes the column on the support by setting an adjustable support layer, so that the column can be reset or adjusted to a set height according to the settlement depth of the structural node. This achieves the effect of releasing forced displacement, while also ensuring that the column is stably supported on the support by the support layer before and after adjustment, reducing the adverse effects on the structure after the main body settles.

[0024] Figure 1 The figure shows a schematic diagram of the structure of this utility model. The adjustable connection node structure in this embodiment includes a column 001 and a support 002. The column 001 is detachably assembled on the support 002. The detachable method includes bolt connection or limit snap connection, etc. The specific structure is determined by the application node position or the application component material, etc., and will not be described in detail here. An adjustable support layer 1 is provided between the column 001 and the support 002. The support layer 1 can be formed by concrete pouring, or it can be composed of a pad or multiple sets of pads set between the column 001 and the support 002 to provide support, or it can be a structure formed by pads and concrete pouring, etc. It is preferable to achieve the purpose of adjustable height between the column 001 and the support 002, and to ensure that the column 001 is stably assembled on the support 002, which will not be described in detail here. By setting an adjustable support layer 1, the column 001 is stably assembled on the support 002, so that the column 001 can be reset or adjusted to a set height according to the settlement depth of the structural node. This achieves the effect of releasing forced displacement, while also ensuring that the column 001 is stably supported on the support 002 by the support layer 1 before and after adjustment, reducing the adverse effects on the structure after the main body settlement.

[0025] This scheme uses cast-in-place concrete as the support layer 1, corresponding to the support 001 at a preset height on the support 002. During construction, the column 001 is first adjusted to the preset position, leaving a pouring area between the column 001 and the support 002. Then, concrete is filled into the pouring area. After the concrete reaches the preset strength, the column 001 and the support 002 are assembled into a whole. The tools for adjusting the column 001 to the preset position can be lifting equipment or jacks, etc., depending on the usage environment, which will not be elaborated here. The advantages of using concrete as the support layer 1 are that the concrete pouring thickness is controllable, the applicability is wide, the concrete material is readily available, the construction is simple and convenient, and the construction efficiency is high. At the same time, the support layer 1 cast by concrete does not cause destructive damage to the existing column 001 structure and support 002 structure, which can ensure the reliable assembly of column 001 and support 002, and improve the support effectiveness and service life of column 001.

[0026] In this embodiment, a fastening assembly is also included. The fastening assembly includes a connector 2 and a fastener 3. A base plate 4 is provided on the column 001. The connector 2 passes through the base plate 4 and is connected to the support 002. The fastener 3 is detachably provided on the connector 2. The base plate 4 is limited to the support 002 by the fastener 3, or can be released from the support 002. The base plate 4 on the column 001 allows for easier and more detachable assembly of the column 001 onto the support 002 via fastening components. The base plate 4 also prevents residual stress on the column 001 during assembly, ensuring a more stable placement of the column 001 on the support 002 and meeting the support requirements of the column 001 at its designated position. This reduces the risk of premature failure of the column 001 due to external forces. The connector 2, which passes through the base plate 4 and connects to the support 002, pre-positions the column 001 on the support 002, further improving the assembly efficiency of the column 001 and support 002. The fastening components can consist of bolts and nuts, pins and columns, mortise and tenon joints, or snap-fit ​​structures. A structure that allows for detachable connection of the column 001 and support 002 while ensuring reliable assembly of the column 001 on the support 002 is preferable; further details will not be elaborated here.

[0027] In this embodiment, the root of the connector 2 is embedded in the support 002, and the head of the connector 2 passes through the base plate 4 and is used to cooperate with the fastener 3 to detachably limit the base plate 4 to the support 002. The root corresponds to the bottom of the connector 2, and the head corresponds to the top of the connector. The connector 2 and the support 002 are prefabricated as a whole, which makes the assembly reliability of the column 001 on the support 002 higher and can further ensure the stability of the column 001 on the support 002. The connector 2 embedded in the support 002 can also provide a certain support force for the column 001 when it is assembled on the support 002. The connector 2 can form a guide for the column 001, which is more conducive to the assembly of the column 001 on the support 002.

[0028] In this embodiment, the circumferential dimension of the base plate 4 exceeds the circumferential dimension of the column 001, and the column 001 is located at the center of the base plate 4; that is, the base plate 4 has reserved an area for mounting fastening components to ensure that the column 001 is stably mounted on the support 002. The fastening components include several sets evenly distributed around the circumference of the column 001 to ensure the reliability of the column 001 mounted on the support 002 and to improve the stability of the column 001 under stress.

[0029] In this solution, the fastening components include anchor bolts pre-embedded in the support 002 as connectors 2 and nuts threadedly fitted onto the head of the anchor bolts as fasteners 3. The anchor bolts are set in a direction parallel to the extension direction of the column 001 to reduce the stress impact of the fasteners 3 on the column 001 and support 002 after assembly. The combination of anchor bolts and nuts has the advantages of reliable connection and easy adjustment, and has sufficient limiting strength to assemble the column 001 onto the support 002. It is also convenient to construct and cost-effective. The nuts also lock the base plate 4 to the support 002 through washers.

[0030] In this embodiment, a stiffening rib 5 is provided between the base plate 4 and the column 001. The stiffening rib 5 includes several pieces located between adjacent fastening components. The stiffening rib 5 can further improve the connection reliability between the base plate 4 and the column 001, and can improve the support capacity and shear resistance of the column 001 base, as well as improve the structural strength of the column 001 base, so as to ensure that the fastening components stably assemble the column 001 onto the support 002.

[0031] In this embodiment, the support 002 is provided with a first shear-resistant member 61 and a second shear-resistant member 62 to clamp the column 001. This improves the shear resistance of the connection node between the column 001 and the support 002, and solves the problem of weak shear resistance at the node when the fastening components are set independently. The first shear-resistant member 61 and the second shear-resistant member 62 can be prefabricated with the support 002 or installed later, depending on the actual construction conditions, which will not be described in detail here.

[0032] In this embodiment, a functional gap is reserved between the first shear member 61 and the column 001 and / or between the second shear member 62 and the column 001. The meaning of "and / or" is that the functional gap can be reserved independently between the first shear member 61 and the column 001 or between the second shear member 62 and the column 001, or it can be reserved simultaneously between the first shear member 61 and the column 001 and between the second shear member 62 and the column 001. A pad is provided in the functional gap, and the pad provided in the functional gap is used to make the first shear member and the second shear member stably clamp the column. The purpose of reserving this functional gap is to facilitate the assembly of the column 001 on the support 002. The use of padding layer 7 to wed the functional gap ensures that the column 001 is stably positioned on the support 002 and is limited by the clamping action of the first shear member 61 and the second shear member 62. In this design, padding layer 7 comprises several steel plates of uniform thickness. Of course, padding layer 7 can also be implemented using jacks with adjustable support range or other padding blocks, which will not be elaborated upon here. In this design, the functional gap is simultaneously reserved between the first shear member 61 and the column 001, and between the first shear member 61 and the second shear member 62. The functional gap between the first shear member 61 and the column 001, and the functional gap between the second shear member 62 and the column 001 are approximately the same, so that the distribution of several steel plates of uniform thickness on both sides is more even and the stability of the node structure is better. In this scheme, the first shear member 61 and the second shear member 62 are reinforced concrete structures and are constructed together with the support 002, making the structure more reliable. It can also further limit the approximate position of the column 001 on the support 002 and improve the assembly efficiency of the connection node.

[0033] In this embodiment, the base plate 4 has a first force-bearing end near the first shear-resistant member 61 and a second force-bearing end near the second shear-resistant member 62. The first shear-resistant member 61 and the second shear-resistant member 62 are respectively close to the first force-bearing end and the second force-bearing end, so as to clamp the column 001 and make the force on the column 001 in the clamping direction basically balanced, so that the column 001 can be more stably and reliably set on the support 002 and has a certain shear resistance. In this solution, the base plate 4 is a square plate, and the column 001 is located at the center of the base plate 4 and fixed thereto. The first force-bearing end and the second force-bearing end are respectively formed on both sides of the base plate 4 corresponding to the first shear-resistant member 61 and the second shear-resistant member 62. The functional gap is formed between the first shear-resistant member 61 and the first force-bearing end, and between the second shear-resistant member 62 and the second force-bearing end.

[0034] In this embodiment, the height of the first shear-resistant member 61 and the height of the second shear-resistant member 62 both exceed the installation height of the base plate 4 on the support 002. The fact that the height of the shear-resistant member and the height of the second shear-resistant member 62 are the same and exceed the installation height of the base plate 4 on the support 002 in this solution improves the assembly reliability of the column base 001 on the support 002, ensures that the shear resistance and support performance meet the predetermined requirements, and provides a certain degree of anti-tilting function when the height of the column 001 is adjusted.

[0035] In this embodiment, a settlement observation point 004 is provided on the column 001. Any existing technology can be used for the settlement observation point 004 in this solution, provided it meets the established monitoring requirements; further details are omitted here. By setting the settlement observation point 004, this solution can directly obtain the settlement height parameters of the structural components, facilitating accurate height adjustment of the column 001, thereby releasing forced displacement, improving the support effectiveness and service life of the column 001, and ultimately ensuring that the overall structure is not affected by settlement.

[0036] When adjusting the height of column 001, the steel plate of the functional gap is removed in advance, and the nuts set on the anchor bolts are loosened one by one. Then, column 001 is adjusted to the specified height so that space is reserved between column 001 and support 002 for pouring concrete. Then, concrete is poured to form a new support layer 1. After the concrete strength is sufficient, column 001 is released and assembled on support 002. Then, the functional gap is filled by wedging with steel plate to complete one adjustment of the height of column 001.

[0037] This embodiment also discloses a C-shaped material yard. The top of the C-shaped material yard uses the adjustable connection node structure of this solution, which can improve the support effectiveness and service life of the column 001. This node structure has reliable connection quality, is easy to install, and is less affected by weather conditions. It is beneficial to improve the longitudinal stability of the upper steel structure of the C-shaped material yard, reduce the overall steel consumption of the steel structure, and has good economic benefits. More specifically, in the length direction of the C-shaped material yard, multiple sets of adjustable connection node structures are provided. The columns 001 corresponding to two adjacent sets of adjustable connection node structures are connected by "X"-shaped diagonal braces 003. The bottom pin of the "X"-shaped diagonal brace 003 is connected to the bottom of the column 001 of the two adjacent sets of adjustable connection node structures, and the top pin of the "X"-shaped diagonal brace 003 is connected to the top of the column 001 of the two adjacent sets of adjustable connection node structures. It should be understood that the first shear member 61 or the second shear member 62 has a clearance groove at the diagonal brace 003 at the bottom of the column 001.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
