Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a building sample node. Background Art

[0002] As the demand for wooden structure buildings continues to increase, the demand for hybrid wooden structure systems is gradually increasing due to the strength properties of wooden component materials themselves.

[0003] In the current light wood structure housing, how to connect the floor joists to the concrete wall has become one of the important nodes. In this node, the end joists are generally connected to the wall first, and then the floor joists are connected to the end joists.

[0004] When connecting the end joists and the wall, the suggestion given in the wood structure design specification is to use pre-embedded steel bars for connection and fixation. Specifically, when pouring the concrete wall, first embed steel bars in the wall so that at least part of the steel bars extend out of the wall as the connection part (with threads). Later, the connection part is passed through the end joists and fixed with nuts. Although this method can realize the connection of the end joists, due to the method of pre-embedded steel bars, the position of the steel bars cannot be changed. Therefore, the end joists can only be connected at a specific height later, which is not flexible enough. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the utility model is to provide a building sample node.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A building sample node includes a wall, a head joist and a floor joist, wherein the head joist is arranged on the wall, and one end of the floor joist is fixed on the head joist. The sample node also includes a pull piece, wherein the head joist is fixed to the wall by a first chemical bolt, wherein the first chemical bolt is located below the center line of the head joist; the pull piece is fixed to the wall and located on the top of the floor joist, and the floor joist is hung on the pull piece.

[0008] Compared with the prior art, the advantages of adopting this solution are:

[0009] Firstly, in this solution, chemical bolts (i.e., first chemical bolts) are used as connectors between the end joists and the wall, so that the installation position of the end joists on the wall can be selected according to actual needs. Compared with the traditional embedded steel bar method, the installation position is undoubtedly more flexible.

[0010] Secondly, in this solution, the first chemical bolt is connected below the center line of the end joist, which can reduce the risk of the end joist being torn, which can be understood as follows:

[0011] As is known to all, the position where the first chemical bolt is inserted into the end joist has a low strength and is prone to cracking. The ends of the floor joists are generally connected to the middle and upper positions of the end joists (generally, the top surface of the floor joists is flush with the top surface of the end joists). In this way, the middle and upper positions of the end joists need to bear the weight of the floor joists, making the middle and upper positions of the end joists more prone to cracking. At this time, if the first chemical bolt is set in the middle and upper positions of the end joists, it will undoubtedly increase the risk of cracking of the end joists. Therefore, in this solution, it is set below the center line of the end joists.

[0012] However, if the first chemical bolt is set below the center line, the head joist and the floor joist will not have a stable connection point with the wall at the top. Therefore, in this solution, a pull piece is set on the top of the floor joist, and the floor grille is pulled upward at the top of the floor joist by the pull piece, so that the floor grille can also have a stable connection point with the wall at the top. In this way, even if the first chemical bolt is set below the center line of the head joist, the entire node can have good stability.

[0013] As an optional implementation manner of the utility model, the pulling member includes a first arm and a second arm, the first arm is fixed on the wall, and the second arm is fixed to the floor joist at the top of the floor joist.

[0014] As an optional implementation manner of the utility model, the first support arm is fixed to the wall through a second chemical bolt, and / or the second support arm is fixed to the floor joist through a screw.

[0015] As an optional implementation manner of the utility model, a floor slab is laid on the top of the floor joist; the floor slab is located between the second support arm and the top surface of the head joist.

[0016] As an optional implementation of the utility model, a plurality of first chemical bolts are sequentially arranged along the length direction of the end joist, wherein the height positions of two adjacent first chemical bolts along the length direction of the end joist are staggered.

[0017] As an optional implementation manner of the utility model, an anti-corrosion layer is provided between the head joist and the wall surface.

[0018] As an optional implementation of the utility model, the anti-corrosion layer includes anti-corrosion wood.

[0019] As an optional implementation manner of the present utility model, the anti-corrosion layer further includes a moisture-proof pad, and the moisture-proof pad is located between the anti-corrosion wood and the wall.

[0020] As an optional implementation of the utility model, the floor joist is connected to the head joist via a hanger, the hanger includes a slot, in the assembled state, the hanger is fixed to the head joist, the end of the floor joist is embedded in the slot and fixed to the hanger.

[0021] Other advantages and effects of the present invention are explained in detail in the specific implementation manner and the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0026] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0027] See also Figure 1-3 As shown, this embodiment provides a building sample node, including a wall 1, a head joist 2, a floor joist 3, and a floor slab 4; wherein the wall 1 is a concrete structure, and the head joist 2, the floor joist 3, and the floor slab 4 are all wooden structures. For example, the head joist 2 is made of SPF standard material, and the floor slab 4 is made of OSB board.

[0028] In this embodiment, the wall 1 is basically arranged vertically, the end joist 2 is fixed to the wall surface of the wall 1 by a plurality of chemical bolts (which are referred to as first chemical bolts 5 for distinction), and the end joist 2 is arranged horizontally and fits the wall surface of the wall 1. Figure 3 As shown, the first chemical bolt 5 penetrates the end joist 2 in a direction perpendicular to the wall surface and penetrates into the wall body 1 to achieve connection between the wall body 1 and the end joist 2. Since chemical bolts are publicly described in the prior art, they will not be described in detail here.

[0029] Chemical bolts (i.e., first chemical bolts 5) are used as connectors between the end joists 2 and the wall 1, so that the installation position of the end joists 2 on the wall 1 can be selected according to actual needs, which is undoubtedly more flexible than the traditional embedded steel bar method.

[0030] In addition, in this embodiment, the first chemical bolt 5 is located below the center line of the end joist 2. The center line here refers to the center line of the end joist 2 in the height direction. Figure 3 As shown in the middle L1.

[0031] The large sample node in this embodiment also includes a pull member 6 , which is fixed on the wall 1 and located on the top of the floor joist 3 , and the floor joist 3 is hung on the pull member 6 .

[0032] The first chemical bolt 5 is connected to a position below the center line of the end joist 2, so as to reduce the risk of the end joist 2 being torn, which can be understood as follows:

[0033] As is known to all, the position where the first chemical bolt 5 is inserted into the end joist 2 has a low strength and is prone to cracking. The ends of the floor joists 3 are generally connected to the middle and upper positions of the end joists 2 (generally, the top surface of the floor joists 3 is flush with the top surface of the end joists 2). In this way, the middle and upper positions of the end joists 2 need to bear the weight of the floor joists 3, which makes the middle and upper positions of the end joists 2 more prone to cracking. At this time, if the first chemical bolt 5 is set at the middle and upper positions of the end joists 2, it will undoubtedly increase the risk of cracking of the end joists 2. Therefore, in this solution, it is set below the center line of the end joists 2.

[0034] However, if the first chemical bolt 5 is set below the center line, the head joist 2 and the floor joist 3 will not have a stable connection point with the wall 1 at the top. Therefore, in this solution, a pull member 6 is set on the top of the floor joist 3, and the floor grille is pulled upward at the top of the floor joist 3 by the pull member 6, so that the floor grille can also have a stable connection point with the wall 1 at the top. In this way, even if the first chemical bolt 5 is set below the center line of the head joist 2, the entire node can have good stability.

[0035] In this embodiment, the floor joists 3 are mainly used for laying the floor slabs 4, and a plurality of floor joists 3 can be provided, and a plurality of floor joists 3 are arranged on the head joists 2 in sequence and at intervals along the length direction of the head joists 2, wherein one end of the floor joist 3 is in contact with the head joist 2.

[0036] Among them, Figure 3 As shown, the top surface of the floor grid is flush with the top surface of the end joist 2, and the floor slab 4 is horizontally laid on the top surface of the floor grid and the top surface of the end joist 2 and fixed by screws.

[0037] In this embodiment, the specific structure of the pull member 6 is that the pull member 6 includes a first arm 61 and a second arm 62. For example, in this embodiment, the pull member 6 can adopt an angle code, and the first arm 61 and the second arm 62 intersect vertically to form an L-shaped structure.

[0038] The first arm 61 is in contact with the wall surface of the wall 1 and is fixed to the wall 1 via a second chemical bolt 7 . The second chemical bolt 7 is arranged perpendicular to the wall surface.

[0039] The second arm 62 is fixed to the floor joist 3 at the top of the floor joist 3. Specifically, the second arm 62 is attached to the top surface of the floor slab 4 and is fixed to the floor joist 3 by vertically arranged screws. At this time, the floor slab 4 is clamped between the second arm 62 and the top surface of the head joist 2.

[0040] In this embodiment, if Figure 2 As shown, along the length direction of the end joist 2, the height positions of two adjacent first chemical bolts 5 are staggered, that is, the two first chemical bolts 5 are arranged one high and one low. The purpose of such arrangement is to avoid the two adjacent first chemical bolts 5 being on the same horizontal line. Once the two first chemical bolts 5 are on the same horizontal line, the strength of the wood (that is, the end joist 2) will be weakened.

[0041] In addition, if the wooden end joist 2 is in direct contact with the wall 1 of the concrete structure, the end of the end joist 2 is prone to rot. Therefore, in this embodiment, an anti-corrosion layer is provided between the end joist 2 and the wall 1. Specifically:

[0042] The anticorrosion layer includes an anticorrosion wood 21 and a moisture-proof pad 22. The anticorrosion wood 21 is sandwiched between the end joist 2 and the wall 1, and the moisture-proof pad 22 is located between the anticorrosion wood 21 and the wall 1. Figure 3 From left to right, the following is: wall 1 - moisture-proof mat 22 - anticorrosive wood 21 - end joist 2. The moisture-proof mat 22 plays a role in moisture-proof and moisture-proofing. The anticorrosive wood 21 has good corrosion resistance and can isolate the end joist 2 from direct contact with the wall 1.

[0043] In this embodiment, Figure 1 As shown, the floor joist 3 is connected to the head joist 2 through a hanger 8, and the hanger 8 includes a slot 81. Specifically, the hanger 8 in this embodiment has a U-shaped structure. In the assembled state, the hanger 8 is fixed to the head joist 2 by a plurality of screws, and the end of the floor joist 3 is embedded in the slot 81 and fixed to the hanger 8 by a plurality of screws, so that the floor grille is supported by the hanger 8.

[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
