Description

Building structures and installation structures of steel trusses on the top floor of building structures

The present application relates to a building structure, in particular to a building structure and a steel truss installation interface on the top floor of the building structure.

Modern buildings are especially about the construction of high-tech factories. Whether the construction progress is rapid directly affects the setting of environmental control of special factories, the positioning of production equipment, and the timeliness of when production will be carried out. Since the investment cost of the high-tech industry is extremely high, it is very important to complete the construction of the high-tech factory building structure as soon as possible to facilitate the installation of factory environmental control and the installation of production equipment.

Due to the building structure of the high-tech factory building, the top floor part has a steel truss structure. When the supporting steel columns of the steel truss are connected to the corresponding column structure of the highest floor of the factory building, they must have horizontal and vertical dimensions. Only with a certain degree of accuracy can each truss of the steel truss be smoothly connected and fixed to each supporting steel column of the steel truss.

However, when the building structure is constructed from the lower floor to the upper floor, the higher the floor, the more difficult it is to keep the column structure of the top floor connected to the supporting steel columns of the steel truss in the transverse and height directions due to the possible increase in construction errors. the required precision. So building a building When constructing the structure, the column structure that will be connected to the supporting steel columns of the steel truss must be connected at the top level of the building structure or at a height close to the top level, so that the connection between the structure of the column structure and the supporting steel columns of the steel truss remains. There is a certain margin for adjustment in the lateral and height directions. In this way, after the supporting steel columns of the steel truss and the column structure are connected, the supporting steel columns can be in the predetermined correct position, so that other trusses can be smoothly connected and installed on the supporting steel columns.

In addition, due to the installation of steel trusses (including the supporting steel columns of the steel trusses), they are usually constructed in a different construction group from the structures that construct other parts of the building structure. If the top floor of the building structure has a column structure with the supporting steel columns of the corresponding steel truss, When connecting with the supporting steel columns, even after manual adjustment, the above required accuracy cannot be achieved, and the steel truss will not be successfully installed. This will cause problems in clarifying construction responsibilities between different construction groups, and will lead to construction management This problem has also caused delays in the construction progress of the building structure and the installation of production equipment, which has caused the cost of factory construction to rise.

Therefore, how to provide a building structure and an installation structure of its steel truss so that the steel truss can be installed quickly and smoothly within an adjustable range is something the industry hopes for.

One of the purposes of this application is to provide a building structure that can adjustably combine the supporting steel column structure of the steel truss with the structural configuration of the column structure on the top floor of the building structure, so that the subsequent trusses of the steel truss can be accurately installed to the steel truss. to support the steel columns and successfully complete the installation of the entire steel truss.

In order to achieve the above purpose, this application proposes a building structure, including: at least one pillar, the at least one pillar including a first steel column and a concrete layer covering a part of the first steel column, and the third steel column is A steel column has an upper section exposed to the outside above the at least one pillar; at least a second steel column, a lower end of the at least one second steel column is exposed to the first steel column The exposed upper section is connected; a steel truss is connected and fixed to the at least one second steel column.

In order to achieve the above purpose, this application also proposes a building structure, including: at least one pillar, the at least one pillar including a first steel column and a concrete layer covering a part of the first steel column, and the The first steel column has an upper section exposed to the outside above the at least one pillar; at least one second steel column has a lower end of the at least one second steel column and the exposed upper section of the first steel column joint; a steel truss jointed and fixed to the at least one second steel column; wherein the exposed upper section of the first steel column of the at least one Xuan column includes a beam-column joint portion, and wherein the at least one One beam structure includes a plurality of beam columns, and the two ends of a beam structure are respectively connected with the beam-column joint portion of the first steel column of each of the two adjacent beam columns of the plurality of beam columns.

The illustrative embodiments set forth herein are intended to illustrate various embodiments of the present application and are not to be construed as limiting the scope of the present application in any way.

Figure 1 shows a simplified structural schematic diagram of a building structure according to an exemplary embodiment of the present application. The building structure 1 in Figure 1 includes the underground floor LB (for example, two different underground floor areas LB1 and LB2), the above-ground floor L (for example, floors L10, L20, L30, L40, and L50), and the uppermost steel truss structure T. The underground floor LB and the above-ground floor L of the building structure are formed by a plurality of column structures 2 , a plurality of beam structures 3 , and a floor layer 4 located between the column structure 2 and the beam structure 3 . The column structure 2 of the exemplary embodiment in FIG. 1 includes a plurality of Xuan columns between floors on the ground floor, and further includes a plurality of main load-bearing columns 5 of the building structure 1 in the form of Xuan columns.

Referring again to Figure 1, the structure of the steel truss T is above the topmost layer of the upper floor L of the building structure 1 (for example, floor L50 in Figure 1), and at a plurality of predetermined positions and the topmost layer of the corresponding position (such as The column structure 2 of floor L50) is connected. For example, in a high-tech factory with a clean room, the upper floor L of the building structure 1 has a part of the area used as the return air area A for the clean room equipment (in Figure 1, the grid-like diagonal lines represent the column structure and the beam structure surrounded by area), and the space above the return air area A, such as the space above floor 4 of floor L50, is constructed as a dust-free high-tech factory building room space S.

FIG. 2 shows a schematic structural diagram of an embodiment of area B of the building structure 1 in FIG. 1 . In the building structure 1 shown in Figure 2, part of the required building structure can be completed in advance, such as the return air area A starting from the underground floor LB1 to the height of floor L50, and other building structures (such as Figure 2). The mesh-like diagonal line part in 2 shows the column structure 2, beam structure 3 and floor layer 4) from Qixuan to the height of floor L50. Then the operator continues to connect at least one 鄐鄄 column 21 upward in the column connection area of floor L50 (two 鐐鄄 columns 21 are shown as an example in Figure 2). The continued 鐐鄄 pillar 21 is made of a first steel The column 211 is composed of a concrete layer 212 covering part of the outer periphery of the first steel column 211 to form an SRC column, and the first steel column 211 has an upper section exposed to the outside above the Qixuan column 21 Department 2111. In addition, a lower end 2111' of at least one second steel column 211' is joined and fixed to the corresponding end of the exposed upper section 2111 of at least the first steel column 211, and then a plurality of trusses of the steel truss T are joined and fixed to the first steel column 211. At least one or more predetermined positions on the two steel columns 211', thereby completing the structural assembly of the steel truss T.

FIG. 3 shows a schematic structural diagram of another embodiment of area B of the building structure 1 in FIG. 1 . In the building structure 1 shown in Figure 3, the required part of the building structure can also be completed in advance (for example, the column structure 2 and the beam structure shown in the grid-shaped diagonal portion from the top to the floor L40 in Figure 3 3 and floor level 4). The difference between the embodiment shown in Fig. 3 and that shown in Fig. 2 is that the operator first partially lifts the hammer to the height of floor L40. Then, at least one Xixuan column 21 is continued upward in the column connection area of floor L40 (two Xixuan columns are shown as an example in Figure 3). The continued Xixuan column 21 is composed of a first steel column 211 and It is composed of a concrete layer 212 covering part of the outer periphery of the first steel column 211, and the first steel column 211 has an exposed upper section 2111 above the Qixuan column 21 (so as to form an SRC column shape. ). It should be noted that the first steel column 211 in Figure 3 is exposed to the outer upper section 2111 above the Xuan column 21, and the end of the upper section 2111 is connected from floor L50 The predetermined height of the surface of the floor layer 4 then protrudes upward for a height H1, and a part of the upper section 2111 includes a beam-column joint portion 2112 for constructing the floor L50. In addition, a lower end 2111' of at least one second steel column 211' is joined to the corresponding end of the exposed upper section 2111 of at least the first steel column 211, and then the truss of the steel truss T is joined and fixed to the second steel column 211', and the structure of the steel truss T is completed. After the above operation is completed, the two ends of the one-piece beam structure 3 are respectively joined to the beam-column joint portion 2112 of the first steel column 211 of each of the two adjacent two-piece columns 21 .

As shown in FIGS. 2 and 3 , the upper section 2111 of the first steel column 211 that is exposed to the outside above the column 21 has different protruding heights above the floor surface of floor L50 . For example, in Figure 2, since the column 21 is continued from the top surface of the floor of floor L50, only a short section of the upper section 2111 of the first steel column 211 is exposed, and is close to the steel truss T the predetermined setting height. It can be seen from Figure 2 that only a small section of the first steel column 211 of the Xiuxuan column 21 is exposed to the outer upper section 2111, and there is a distance D1 between it and the lowest horizontal frame of the steel truss T, and the second The joint between a lower end 2111' of the steel column 211' and the corresponding end of the upper section 2111 exposed by at least the first steel column 211 is at a position between the distance D1.

As another example in Figure 3, since the column 21 is continued from the top surface of the floor of floor L40, the upper end of the first steel column 211 is exposed to the outside and the upper section 2111 protrudes from the floor of floor 50. The top surface has a vertical height H1, which is further away from the intended height of the steel truss T than the structure shown in Figure 2. As can be seen from Figure 3, there is a distance D2 between the exposed upper section 2111 above the first steel column 211 of the Xiuxuan column 21 and the lowest cross frame of the steel truss T, and the second steel column 211' The joint between a lower end 2111' and the corresponding end of the upper section 2111 exposed by at least the first steel column 211 is at a position between the distance D2.

The first steel column 211 and the second steel column of different embodiments shown in Figures 2 and 3 The vertical height position of the joint 211' on floor L50 is different, so the length of the second steel column 211' in Figures 2 and 3 is also different. For example, in Figure 2, the length of the second steel column 211' is shorter, and a height of at least 1 meter (or more than 1 meter) is reserved for the distance D1. On the contrary, in Figure 3, the length of the second steel column 211' is longer, and the above-mentioned distance D2 is also larger than the distance in Figure 2. Since the trusses of the steel truss T must have a certain degree of accuracy when connected to the second steel column 211', multiple trusses can be accurately connected to each other and the final structure of the steel truss T can be completed. Therefore, when joining the end of the upper section 2111 of the first steel column 211 with the lower end 2111' of the second steel column 211', the installation accuracy of the second steel column 211' in the lateral direction and height direction must be accurately adjusted. Only in this way can the subsequent truss connection work be carried out smoothly. In other words, if the installation accuracy of the second steel column 211' is poor after the second steel column 211' is joined to the first steel column 211, it will be difficult to successfully join and install the subsequent trusses of the steel truss T.

In the embodiment shown in FIG. 2 , the length of the second steel column 211 ′ is shorter than the length of the second steel column 211 ′ in the embodiment shown in FIG. 3 . In other words, the vertical height of the joint between the second steel column 211' and the first steel column 211 at floor L50 in Figure 2 is relatively high. Therefore, the second steel column 211' in the embodiment shown in Figure 2 is adjusted during the joint. The margins in the lateral and height directions are small. On the contrary, in Figure 3, the vertical height of the joint between the second steel column 211' and the first steel column 211 at floor L50 is relatively low. Therefore, the second steel column 211' in the embodiment shown in Figure 3 is adjusted laterally during the joint. The margin in direction and height is larger. Therefore, in the embodiment of FIG. 2 , at least when installing the pillars 21 on floor L50, the accuracy in the transverse direction and the height direction must be relatively high, so that the second steel pillar 211 ′ can be aligned with the first steel pillar. 211 when joining, the second steel column 211' can be adjusted with a margin sufficient to enable each truss to be accurately joined to the second steel column 211', thereby enabling the steel truss T to be successfully installed. In the embodiment of FIG. 3, since the second steel column 211' is longer and the vertical height of the joint with the first steel column 211 is lower, the second steel column 211' is given a larger adjustment margin during the joint. degree, so Figure 3 In the embodiment shown, when the steel column 21 is continued on the floor L40, the accuracy in the transverse direction and the height direction does not need to be as high as the embodiment shown in Figure 2, but the second steel column 211' can still be made to have Sufficient adjustment margin. However, the construction process of the joining method of the first steel column and the second steel column shown in Figure 3 is relatively complicated and requires more processes than that shown in Figure 2. Both have their own advantages and disadvantages.

In the embodiments of Figures 2 and 3, if necessary, during the scheduled construction process of the building structure 1, areas with lattice structures (such as column structures or beam structures in the network diagonal area) and areas with cast structures ( For example, the beam structure 3 and floor layer 4) shown in the non-network diagonal area in Figure 2 are used to allocate appropriate manpower and operating procedures. Especially in the embodiment shown in FIG. 3 , since the first steel column 211 in FIG. 3 is exposed to the outer upper section 2111 above the Xuan column 21 , it includes a beam column for constructing the floor L50 The joint portion 2112, therefore between the position of the beam-column joint portion 2112 of each of the two adjacent first steel columns 211, and the adjacent beam structure 3, is achieved by field casting. It should be noted that in the embodiment shown in Figure 3 , after the beam structure 3 and the floor of floor L50 have been cast in the field, the operators use formwork to cover the joined first steel column 211 from the floor of floor L50. and the second steel column 211' to a predetermined height at a predetermined distance from the lowest truss of the steel truss T, and pour mortar to form a portion of the first steel column 211 and the second steel column 211 that are joined to each other at floor L50. Another layer of concrete for part of the steel column 211'.

As can be seen from the embodiments of Figures 2 and 3, no matter in the embodiment shown in Figure 2 or Figure 3, the first steel column 21 connected to the second steel column 211' is continuously connected to the second steel column 211' of the second steel column 211'. On a top surface (such as the top surface of the floor layer 4 in Figures 2 and 3), a return air area A is formed below the top surface.

Figure 1 also shows that the building structure 1 has a plurality of main load-bearing columns 5, which can be used as, for example, the central column of the building structure 1. Since the load-bearing columns are directed from the basement floor LB of the building structure 1, It is constructed up to the top floor of the building structure (for example, the height of floor L50 in Figure 1), which must be able to maintain sufficient accuracy in the transverse direction and height direction, so that the top of the load-bearing column and the second part of the adjacent steel truss The steel columns can have sufficient adjustment margin so that the truss of the steel truss T can be installed smoothly, which is quite difficult. Therefore, the load-bearing columns are constructed in sections. For example, in Figure 1, the load-bearing column 5 includes a first column structure 51, a second column structure 52 and a third column structure 53 from the bottom to the top of the building structure 1. The first column structure 51 of the load-bearing column 5 is set in one of the underground floors LB of the building structure, and can be a structural column in the form of a cast RC column or a cast RC column. The second column structure 52 of the load-bearing column 5 is arranged on one of the above-ground floors L of the building structure and is connected to the first column structure 51. The second column structure 52 is a column structure of a RC column type. The third column structure 53 of the load-bearing column 5 is disposed above the second column structure 52 and connected to the second column structure 52 . The third column structure 53 of the load-bearing column 5 is constructed, for example, in the form of an SRC column, which has a first steel column 531 and an exposed upper section 5311 above the first steel column 531 (as shown in FIG. 8 ).
