Description

Technical Field

[0001] The present invention relates to the technical field of ALC board installation, and more specifically, to an external hanging connection structure for ALC strip boards. Background Art

[0002] The exterior wall is the main enclosure structure of a building, which has an important impact on the safety and service functions of the building. ALC boards have excellent properties such as light weight, sound insulation, heat insulation, and fire resistance, and are easy and quick to install. In recent years, they have been increasingly used in the exterior enclosure structure.

[0003] At present, the connection methods of ALC boards as the exterior enclosure structure mainly include two methods: embedded type and external hanging type. Among them, the external hanging connection form does not provide additional stiffness to the structure. Under the action of horizontal forces, the load transfer is more clear, and the ALC boards are continuous at the upper and lower layer junctions, and no additional heat insulation measures are required at the junctions.

[0004] However, the commonly used external hanging connection nodes of ALC boards have a large amount of welding work, slow construction speed, and the welding process is usually a weak link in quality, with a relatively high risk of potential safety hazards. Especially for thick boards, the load is greater and the safety risk is higher. Therefore, it is necessary to propose a simple and feasible external hanging connection node for ALC boards. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an external hanging connection structure for ALC strip boards, in which the force transmission path of the connection node is clear, the amount of welding work is effectively reduced, the construction speed is faster, and the quality is easier to control.

[0006] The solution adopted by the present invention to solve the technical problem is as follows:

[0007] An external hanging connection structure for ALC strip boards, comprising an external hanging structure one installed on the outside of the structural beam of the current floor and used for fixing the bottom of the ALC strip board, and an external hanging structure two installed on the outside of the structural beam of the upper floor and used for fixing the upper part of the ALC strip board;

[0008] The external hanging structure one includes a pre-embedded steel plate installed on the outside of the structural beam of the current floor, a support bracket connected to the outside of the pre-embedded steel plate, and two groups of support angle steels installed on the support bracket and arranged horizontally;

[0009] The two groups of support angle steels support to form an installation groove for installing the ALC strip board.

[0010] Compared with the prior art, when using the present invention for external hanging of ALC boards, the main welding work is at the position of the support bracket, reducing the welding points, thus effectively achieving the purpose of reducing the on-site welding work amount, improving the construction efficiency, and reducing the risk of welding quality defects.

[0011] The present invention restricts the displacement of the ALC board in the horizontal direction through the vertical limbs of two groups of supporting angle steels. Compared with the traditional method using hook bolts and support plates, the reliability is higher, effectively reducing the risk of the ALC strip board falling off under the action of earthquake and wind loads.

[0012] When the ALC board is externally hung and installed using the present invention, the vertical load of the ALC strip board is transmitted to the supporting bracket through the supporting angle steel and finally transmitted to the main structure. The horizontal load is transmitted to the main structure through the external hanging structure II and the external hanging structure I. The force transmission path is simple and clear, and the design is simple.

[0013] In some possible implementation manners, in order to effectively achieve the external hanging installation and fixation of the upper part of the ALC board;

[0014] The external hanging structure II includes embedded angle steels arranged horizontally and installed at the outer corner parts of the bottom of the upper-layer structural beam.

[0015] In some possible implementation manners, in order to ensure the installation of the upper part of the ALC board and effectively transmit the horizontal load of the ALC board to the main structure;

[0016] The embedded angle steel is wrapped outside the corner part of the upper-layer structural beam;

[0017] The external hanging structure II further includes connecting angle steels installed at the bottom of the embedded angle steel, and a plurality of groups of hook bolts vertically connected to the outside of the connecting angle steels and connected to the ALC strip board.

[0018] In some possible implementation manners,

[0019] The outer side surface of the embedded angle steel is in the same plane as the outer side surface of the upper-layer structural beam.

[0020] In some possible implementation manners, in order to effectively achieve the fixation of the embedded steel plate;

[0021] The embedded steel plate includes a plate body located outside the structural beam of this layer, beam anchor bars connected to the inner side surface of the plate body and extending into the structural beam of this layer, and plate anchor bars connected to the inner side surface of the plate body and extending into the structural slab of this layer.

[0022] In some possible implementation manners,

[0023] The outer side surface of the plate body is in the same plane as the outer side surface of the structural beam.

[0024] In some possible implementation manners,

[0025] The openings of the two groups of supporting angle steels are arranged on the side close to each other.

[0026] In some possible embodiments, to effectively support the supporting angle steel;

[0027] The supporting bracket includes a horizontal plate arranged transversely and connected to the outer side of the plate body, and vertical plates respectively connected to the bottom of the horizontal plate and the outer side of the plate body, and the supporting angle steel is installed on the horizontal plate.

[0028] In some possible embodiments, to effectively seal the gaps between the ALC panels between the upper and lower layers and the gaps caused by the vertical plates along the vertical direction;

[0029] The width of the horizontal plate is less than the width of the ALC panel; a groove A is formed between the supporting angle steel on the side away from the structural beam of this layer and the end face of the horizontal plate on the side away from the structural beam, and a groove B is formed between the vertical plate and two adjacent ALC panels; sealant is filled in the groove A and the groove B.

[0030] In some possible embodiments, the outer side surface of the supporting angle steel is in the same plane as the outer side surface of the ALC panel.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] The present invention greatly reduces the on-site welding workload; welding is mainly carried out on the connections between the supporting bracket and the embedded steel plate, and between the connecting angle steel and the hook bolts, so as to reduce the on-site welding operation amount, improve the construction efficiency, and reduce the risk of welding quality defects;

[0033] The present invention improves the connection safety; in one ALC panel, its lower part restricts the out-of-plane displacement through the vertical legs of two supporting angle steels, which is more reliable compared with the traditional method using hook bolts and support plates, and effectively reduces the risk of the ALC panel falling off under the action of earthquake and wind loads.

[0034] The force transmission path of the present invention is simple and clear, and the design is simple; when installing with the present invention, the vertical load of the ALC panel is transmitted to the supporting bracket through the supporting angle steel and finally to the main structure, and the horizontal load is transmitted to the main structure through the supporting angle steel at the lower end and the hook bolts at the upper end, and the force transmission path is simple and clear, and the design is simple;

[0044] The present invention will be described in detail below.

[0045] As Figures 1-6 shown:

[0046] The solution adopted by the present invention to solve the technical problems is:

[0047] An external hanging connection structure for an ALC slab 30, comprising an external hanging structure one 1 installed on the outer side of the structural beam 10 of this layer and used for fixing the bottom of the ALC slab 30, and an external hanging structure two 2 installed on the outer side of the structural beam 20 of the upper layer and used for fixing the upper part of the ALC slab 30;

[0048] The external hanging structure one 1 includes a pre-embedded steel plate 11 installed on the outer side of the structural beam 10 of this layer, a support bracket 12 connected to the outer side of the pre-embedded steel plate 11, and two groups of support angle steels 13 installed on the support bracket 12 and arranged horizontally;

[0049] The two groups of support angle steels 13 support to form an installation groove for installing the ALC slab 30.

[0050] Compared with the prior art, when using the present invention for external hanging of the ALC slab 30, the main welding work is at the position of the support bracket 12, reducing the welding points, thereby effectively achieving the purpose of reducing the on-site welding operation amount, improving the construction efficiency, and reducing the risk of welding quality defects.

[0051] The present invention restricts the displacement of the ALC slab 30 in the horizontal direction through the vertical limbs of the two groups of support angle steels 13. Compared with the traditional method using hook bolts 23 and support plates, the reliability is higher, effectively reducing the risk of the ALC slab 30 falling off under the action of earthquake and wind loads.

[0052] When using the present invention for external hanging installation of the ALC slab 30, the vertical load of the ALC slab 30 is transmitted to the support bracket 12 through the support angle steels 13 and finally transmitted to the main structure, while the horizontal load is transmitted to the main structure through the external hanging structure two 2. The force transmission path is simple and clear, and the design is simple.

[0053] In some possible implementation manners, in order to effectively achieve the external hanging installation and fixation of the upper part of the ALC slab 30;

[0054] The external hanging structure two 2 includes a pre-embedded angle steel 21 arranged horizontally and installed at the outer corner of the bottom of the structural beam 20 of the upper layer;

[0055] In some possible implementation manners, in order to ensure the installation of the upper part of the ALC slab 30 and effectively transmit the horizontal load of the ALC slab 30 to the main structure;

[0056] The pre-embedded angle steel 21 wraps the outer side of the corner of the structural beam 20 of the upper layer; that is, the inner surface of the 90-degree angle of the pre-embedded angle steel 21 fits the outer corner of the structural beam 20 of the upper layer close to the structural beam 10 of this layer; the pre-embedded angle steel 21 is installed in this position by pre-embedding;

[0057] The external hanging structure two 2 further includes a connecting angle steel 22 installed at the bottom of the embedded angle steel 21, and a plurality of sets of hook bolts 23 that are vertically connected to the outside of the connecting angle steel 22 and connected to the ALC strip board 30.

[0058] The embedded angle steel 21 is mainly used for connecting the connecting angle steel 22 to the upper structure beam 20, so as to enable the hook bolt 23 to fix the ALC strip board 30;

[0059] Furthermore, one end of the hook bolt 23 will pass through the ALC strip board 30 and be welded to the connecting angle steel 22;

[0060] During use, the horizontal load is transmitted to the main structure through the supporting angle steel 13 at the lower end and the hook bolt 23 at the upper end, and the force transmission path is simple and clear, and the design is simple.

[0061] In some possible implementation manners, in order to make the construction more convenient; to avoid gaps between the structure beam and the ALC strip board 30;

[0062] The outer side surface of the embedded angle steel 21 is in the same plane as the outer side surface of the upper structure beam 20.

[0063] In some possible implementation manners, in order to effectively fix the embedded steel plate 11;

[0064] The embedded steel plate 11 includes a plate body 111 located outside the structure beam of this layer, a beam anchor bar 113 connected to the inner side surface of the plate body 111 and extending into the structure beam of this layer, and a plate anchor bar 112 connected to the inner side surface of the plate body 111 and extending into the structural slab of this layer.

[0065] Furthermore, the length of the plate anchor bar 112 is greater than the length of the beam anchor bar 113 in the horizontal direction, and the beam anchor bar 113 adopts a bent anchor form to meet the requirement of the anchorage length.

[0066] In some possible implementation manners, in order to make the construction more convenient; to avoid gaps between the structure beam and the ALC strip board 30;

[0067] The outer side surface of the plate body 111 is in the same plane as the outer side surface of the structure beam.

[0068] In some possible implementation manners,

[0069] The openings of the two groups of the supporting angle steels 13 are arranged on the side close to each other.

[0070] The opening described herein specifically refers to the 90° angle of the supporting angle steel 13; the two 90° angles are arranged on the side close to each other, so that the horizontal plate of the supporting angle steel 13 serves as a supporting plate to connect with the supporting bracket 12, and an installation groove for installing the ALC strip board 30 will be formed between the vertical plates of the two groups of supporting angle steels 13, so that the width can be adjusted according to the width of the ALC strip board 30, avoiding the horizontal movement of the ALC strip board 30 after installation.

[0071] In some possible embodiments, in order to effectively support the supporting angle steel 13;

[0072] The supporting bracket 12 includes a horizontal plate 121 arranged horizontally and connected to the outer side of the plate body 111, and vertical plates 122 respectively connected to the bottom of the horizontal plate 121 and the outer side of the plate body 111, and the supporting angle steel 13 is installed on the horizontal plate 121.

[0073] On the one hand, the supporting bracket 12 can support the supporting angle steel 13, and on the other hand, it can transfer the horizontal load, directly transferring the horizontal load of the ALC strip board 30 to the main structure;

[0074] In some possible embodiments, in order to effectively seal the gap between the ALC strip boards 30 between the upper and lower layers and the gap caused by the vertical plate 122 along the vertical direction;

[0075] The width of the horizontal plate 121 is smaller than the width of the ALC strip board 30; a groove A is formed between the supporting angle steel 13 on the side away from the structural beam 10 of this layer and the end face of the horizontal plate 121 on the side away from the structural beam, and a groove B is formed between the vertical plate 122 and two adjacent ALC boards; a sealant 14 is filled in the groove A and the groove B.

[0076] The sealant 14 seals the gap formed between the supporting bracket 12 and the ALC strip board 30, preventing moisture from entering the gap from this position; preferably, the sealant 14 is a weather-resistant sealant.

[0077] In some possible embodiments, the outer side surface of the supporting angle steel 13 is in the same plane as the outer side surface of the ALC strip board 30.

[0078] In order to make the installed ALC strip board 30 more beautiful, the outer side surface of the vertical plate of the supporting angle steel 13 is in the same plane as the outer side surface of the ALC strip board 30;

[0079] On the ALC slab 30, there are also bolt holes for the hook bolts 23 to pass through. During installation, one end of the hook bolt 23 passes through the bolt hole from the end close to the connecting plate to the other end. The end of the hook bolt 23 away from the connecting angle steel 22 is screwed through a nut, and the other end is connected to the connecting angle steel 22 by welding.

[0080] The present invention greatly reduces the on-site welding workload; the welding is mainly on the connections between the supporting bracket 12 and the embedded steel plate 11, and between the connecting angle steel 22 and the hook bolt 23, thereby reducing the on-site welding operation volume, improving the construction efficiency, and reducing the risk of welding quality defects.

[0081] The present invention improves the connection safety; in one ALC slab 30, its lower part is restricted from displacing out of the plane by the vertical limbs of two supporting angle steels 13. Compared with the traditional method using hook bolts 23 and support plates, the reliability is higher, effectively reducing the risk of the ALC slab 30 falling off under the action of earthquake and wind loads.

[0082] The present invention has a simple and clear force transmission path and a simple design;

[0083] When the present invention is used for installation, the vertical load of the ALC slab 30 is transmitted to the supporting bracket 12 through the supporting angle steel 13 and finally transmitted to the main structure. The horizontal load is transmitted to the main structure through the supporting angle steel 13 at the lower end and the hook bolt 23 at the upper end. The force transmission path is simple and clear, and the design is simple.

[0084] The present invention can adapt to ALC slabs 30 with various plate thicknesses and storey heights, and coordinates the construction errors of the main structure through the supporting bracket 12, the connecting angle steel 22 and the supporting angle steel 13, thereby ensuring the rapid progress of on-site installation work.
