The technical solution of the present invention will be further described with reference to the following examples and drawings.

Referring to fig. 1 and fig. 2, a first aspect of the present invention discloses an air shaft sandwich structure 1, and the air shaft sandwich structure 1 can be applied to a building to realize the arrangement of an air duct 230. Specifically, the building comprises a first member 21 and a second member 22, wherein the first member 21 and the second member 22 are arranged at intervals; the air shaft sandwich structure 1 includes a keel 10, a fire prevention plate 20, and a partition wall 30. The keel 10 comprises a first keel section 11 and a second keel section 12 which are connected in sequence, the first keel section 11 is used for being connected to a first member 21, the second keel section 12 is used for being connected to a second member 22, so that an air shaft space 23 for accommodating an air pipe 230 is formed among the first member 21, the first keel section 11, the second keel section 12 and the second member 22, and at least part of the second keel section 12 is arranged at a position corresponding to the interval of the first member 21 and the second member 22; the fire-proof plate 20 is arranged on one side of the second keel section 12, which is positioned in the air shaft space 23; at least one partition wall 30 is located in the air shaft space 23, the at least one partition wall 30 is adapted to be connected to the first member 21 and/or the second member 22, and the at least one partition wall 30 is connected to the fire shield 20.

Alternatively, the fire protection plate 20 may be made of a fire-resistant plate, such as a fiber-reinforced silicate plate, a color steel rock wool sandwich plate, a fire-resistant gypsum plate, or the like, according to design requirements.

Adopt the scheme of this application, can utilize fossil fragments 10 to set up the basic frame of air-out shaft sandwich structure 1, the rethread sets up PLASTIC LAMINATED 20 and partition wall 30, encloses to close to air-out shaft space 23 and seals. The use of the structure can avoid pouring reinforced concrete as a sandwich plate, save the step of wet operation, simplify the process of construction operation, shorten the construction period and be beneficial to the improvement of the construction efficiency on the premise of meeting the requirements of building strength and fire resistance. On the other hand, because the combination structure of the keel 10 and the fireproof plate 20 is simple, the difficulty of modification construction is greatly reduced under the condition that the position of the air shaft or the height of the interlayer needs to be changed due to the adjustment of the plane layout, and the flexibility of modification of the interlayer structure of the air shaft is improved.

For example, when the number of the partition walls 30 is one, one end of the partition wall 30 may be connected to the first member 21 or the second member 22, and the other end thereof may be connected to the fireproof plate 20. When the partition walls 30 are two, the bottoms of both the partition walls 30 are connected to the fireproof plate 20, and the tops of both the partition walls 30 are connected to the first and

second members

21 and 22, respectively. It will be appreciated that the partition wall 30 may be one or two, and when the second member 22 is connected to the second keel section 12, the partition wall 30 may be one, for example, the second member 22 may extend to connect to the portion of the second keel section 12 where the fire retardant panel 20 is located, and in this case the partition wall 30 may be located only between the first member 21 and the second keel section 12 (as shown in figure 1, for example). When there is a space between the first member 21, the second member 22 and the second keel section 12, the partition walls 30 may be two, so that the two partition walls 30 can connect the first member 21, the second member 22 and the fire-proof plate 20 (for example, as shown in fig. 2).

In some embodiments, at least one of the partition walls 30 is provided with an opening 31 communicating with the air shaft space 23, the opening 31 being adapted for the passage of an air duct 230; the inner wall surface of the opening 31 is provided with a sealing structure 32, and the sealing structure 32 is used for sealing between the inner wall surface of the opening 31 and the air duct 230. Illustratively, the duct 230 may be in the shape of a bent tube, one section of the duct 230 being in the shaft space 23 and the other bent section being bent out from the underside of the first member 21 or the second member 22 to facilitate the communication of the indoor duct into the shaft space 23. Illustratively, when the partition wall 30 is disposed between the fireproof plate 20 and the first member 21, the partition wall 30 is opened with a hole 31, and the bent section of the air duct 230 may pass through the hole 31.

Through the arrangement of the hole 31 and the sealing structure 32, the air duct 230 can pass through the hole 31, and the air duct 230 can extend out of the air shaft space 23 to be connected with indoor pipelines conveniently. The sealing structure 32 can seal the gap between the air duct 230 and the first member 21 and the fire shield 20. The isolation of the air shaft space 23 from the indoor space of the building is ensured to meet the design requirements of fire prevention and fire resistance.

Illustratively, the sealing structure 32 may be a sealant or cement mortar, or the like. As shown in fig. 2, a partition wall 30 may be provided between the fireproof plate 20 and the second member 22, in which case a hole 31 may be provided in the partition wall 30, and the specific arrangement of the sealing structure 32 is the same as that of the previous embodiment. The position of the partition wall 30 where the opening 31 is located is not limited in this embodiment, and may be set according to the actual building design requirement.

In some embodiments, at least one partition 30 is a lightweight wallboard or block partition. The partition wall 30 may be made of a light panel wall, such as an aerated concrete wall panel, an inorganic precoat, a calcium silicate panel, or the like, having a fire-resistant property. The panel structure is convenient to construct and install, and optional kind is abundant, can further shorten the engineering time, improves the efficiency of construction. The partition wall 30 can also be a block partition wall, and can also meet the fire-resistant requirement.

In some embodiments, a top end of at least one partition wall 30 is connected to first member 21 and/or second member 22 by angle 33, and a bottom end of at least one partition wall 30 is connected to fire shield 20 by angle 33. For example, when the partition wall 30 is one, the partition wall 30 may be connected to the first member 21 or the second member 22 by an angle 33, and when the partition wall 30 is two, both the partition walls 30 may be connected to the first member 21 and the second member 22 by an angle 33. In this way, partition wall 30 enables a simple and effective connection to first member 21, second member 22 and fire shield 20. For example, when partition 30 is a lightweight wall panel, angle 33 enables partition 30 to be quickly installed and secured between first or

second member

21, 22 and fire shield 20. When the partition wall 30 is a block partition wall, cement mortar can be filled between the partition wall 30 and the fireproof plate 20 to improve the stability of connection.

In some embodiments, the wind shaft sandwich structure 1 further comprises a connection plate 110, the connection plate 110 being adapted to be connected between the first keel segment 11 and the first member 21. Illustratively, the connection plate 110 may be a metal plate, such as a steel plate or a stainless steel plate. On the one hand, the steel plate and the keel 10 are usually made of metal, and the steel plate and the keel are easily connected by welding and the like, so that the connection strength is improved. On the other hand, the connection plate 110 can increase the contact area between the first keel section 11 and the first member 21, reduce the pressure at the contact position, and improve the reliability of the connection between the first keel section 11 and the first member 21.

In some embodiments, or the connection plate 110 is connected to the first member 21 by a first fastener 111, the first keel segment 11 is welded to the connection plate 110.

Alternatively, the first fastener 111 may be a chemical bolt, an expansion bolt, or the like. Considering that the material of the connecting plate 110 is different from that of the first member 21 in general, it is difficult to connect by welding. Therefore, the connection plate 110 can be effectively fixed to the first member 21 using the first fastener 111. Illustratively, when the first fastening member 111 is a chemical bolt, it can bond the anchor and the hole wall of the bolt by using a synthetic resin mortar, so that the bolt, the connecting plate 110 and the first member 21 form a whole, thereby achieving the effects of fixing the connecting plate 110 and improving the bearing capacity of the first member 21.

Optionally, the first keel segment 11 may be welded to the connecting plate 110, and the first keel segment 11 and the connecting plate 110 are usually made of metal, and are connected by welding, so that the connection strength can be improved, and the connection reliability can be ensured.

In some embodiments, it will be appreciated from the foregoing that the second member 22 may extend directly to be connected to the portion of the second runner section 12 provided with the flame retardant panel 20, or alternatively, the second member 22 may be spaced from the portion of the second runner section 12 provided with the flame retardant panel 20.

As an example, when the second member 22 extends directly to connect to the portion of the second keel section 12 where the fire retardant panel 20 is located, the second keel section 12 may be connected to the second member 22 by way of, for example, angle steel, angle iron, or the like.

As shown in fig. 1, when the second member 22 is a wall, that is, when the air shaft sandwich structure 1 is disposed against a wall, the air shaft sandwich structure 1 further includes a second fastening member 220 and a supporting structure 221, the second fastening member 220 is used for fixing the supporting structure 221 to the second member 22, the supporting structure 221 is located outside the air shaft space 23, and the supporting structure 221 is connected to the second keel section 12 to support the second keel section 12. Illustratively, the second fastener 220 is coupled to the second member 22, the second fastener 220 may be, for example, a chemical bolt, an expansion bolt, or the like, and the support structure 221 may be an angle iron, or the like. Taking the supporting structure 221 as an angle steel as an example, the angle steel is fixed to the second member 22 through an expansion bolt, and the second keel section 12 is placed on the angle steel. Thus, when the air shaft sandwich structure 1 is arranged against a wall, the second member 22 is generally a vertical wall, the second keel section 12 is arranged in a substantially horizontal direction, and the second fastener 220 and the support structure 221 can be used for providing a support point for the second keel section 12, so that the second keel section 12 and the second member 22 which are different in moving direction can be stably connected, and a frame for providing a foundation for arranging the fireproof plate 20 is provided.

As another example, when the second member 22 is spaced apart from the portion of the second keel section 12 where the fire-proof plate 20 is disposed, please refer to fig. 2, in this case, the second keel section 12 includes a first sub-keel section 120 and a second sub-keel section 121 connected to the first sub-keel section 120, the first sub-keel section 120 is connected to the first keel section 11, the second sub-keel section 121 is used for being connected to the second member 22, and the fire-proof plate 20 is disposed on a side of the first sub-keel section 120 facing the air shaft space 23. Correspondingly, the partition wall 30 includes a first partition wall 310 and a second partition wall 320 spaced apart from the first partition wall 310, the first partition wall 310 is configured to be connected to the first member 21 and the fire prevention plate 20, and the second partition wall 320 is configured to be connected to the second member 22 and the fire prevention plate 20.

For example, when the air shaft is not disposed against a wall, the first member 21 and the second member 22 may be a cross beam or the like in a building, and the first keel section 11, the first sub-keel section 120, and the second sub-keel section 121 are disposed, and three keels are sequentially connected to form a "U" shaped support frame, so that the fire-proof plate 20 and the partition wall 30 can be effectively supported. Therefore, the air shaft interlayer structure for pouring reinforced concrete can be omitted, the construction period is shortened, and the convenience and the construction efficiency of air shaft interlayer construction are improved.

In some embodiments, to connect the second member 22 to the second sub-keel segment 121, a connecting plate 110 may be provided to connect between the second sub-keel segment 121 and the second member 22. The connection plate 110 may be connected to the second member 22 by a first fastener 111. The second cross runner segment 121 may be welded to the connection plate 110 to effect a connection with the second member 22. For a specific embodiment, reference may be made to the connection manner between the first member 21 and the first keel segment 11, which is not described herein again.

In a second aspect, the embodiment of the present invention further provides a building, the building includes the above-mentioned first member 21, second member 22 and the above-mentioned air shaft sandwich structure 1, the second member 22 and the first member 21 are arranged at an interval, and the first keel section 11 and the second keel section 12 of the air shaft sandwich structure 1 are respectively connected to the first member 21 and the second member 22.

Through the setting of aforementioned air shaft sandwich structure 1, can set up air shaft sandwich structure in the building high efficiency, improve the efficiency of construction. Meanwhile, the air shaft sandwich structure 1 in the embodiment enables the air shaft structure to be more flexible, and the difficulty of later-stage modification is reduced.

In some embodiments, as shown in FIG. 1, when the second member 22 extends directly into connection with the second runner section 12, the second member 22 may be provided with a recess 222 based on the consideration that the flame retardant panel 20 is to be connected to the second member 22, with the side of the flame retardant panel 20 facing the second member 22 extending at least partially into the recess 222. By providing the groove 222, the contact area between the fire shield 20 and the second member 22 is increased, and the connection strength between the fire shield 20 and the second member is improved, so that the arrangement of the fire shield 20 is more stable.

Further, a filler structure 223 is disposed in the recess 222, and the filler structure 223 is used to secure the portion of the fire retardant panel 20 that extends into the recess 222 to the recess 222. Illustratively, the filling structure 223 may be cement mortar or a sealant. By providing the filling structure 223, on the one hand, the space in which the portion of the fire shield 20 that extends into the groove 222 is within the groove 222 can be reduced, and the function of stabilizing the fire shield 20 can be achieved.
