The following describes a timber welded laminated floor assembly 100 according to an embodiment of the present invention with reference to the drawings. The utility model provides a timber welding lamination floor assembly 100 wholly is wood system structure, mainly used repairs or builds timber structure house.
According to the utility model discloses a timber welding lamination lumber floor assembly 100, as shown in figure 1, include: splicing the floor slab 1 and the connecting beam 2. Referring to fig. 4, the spliced floor slab 1 includes a plurality of laminated materials 11, the laminated materials 11 are stacked in a thickness direction (the thickness direction refers to the thickness direction of the laminated materials 11), and each two adjacent laminated materials 11 are welded by using the wooden nails 4. Here, the term "welding" of the wooden nail 4 means that the wooden nail 4 and the wooden piece are instantaneously connected at a high speed, and the short wood is melted, so that the wooden nail 4 and the wooden pieces are firmly connected and have few gaps. The utility model discloses in the welding of dowel 4, all be suitable for this explanation, will not do the perusal. Such as: when the wooden nails 4 are used for welding the two layers of laminated wood 11, transient hot melting is generated when the two layers of laminated wood 11 are connected, and the gaps at the connecting position are few. For another example, when the connecting beam 2 and the spliced floor slab 1 are welded by the wooden nails 4, a short hot melt is formed at the joint between the connecting beam 2 and the spliced floor slab 1, and the joint has few gaps and is not easy to deform. For example, the connecting plate 3 and the flange 21 are welded by the wood nails 4, and the connecting plate 3 and the spliced floor slab 1 are welded by the wood nails 4, so that the short-time hot melting is formed at the joint connection between the connecting plate 3 and the flange 21 and the joint connection between the connecting plate 3 and the spliced floor slab 1, the joint gap is small, and the deformation is not easy.
As shown in fig. 1, the connecting beam 2 is connected to the end of the spliced floor slab 1, and the connecting beam 2 and the spliced floor slab 1 are welded by using the wooden nails 4.
As shown in fig. 2, a cavity 23 is formed between the coupling beam 2 and the spliced floor slab 1. That is, when the coupling beam 2 is coupled to the end of the spliced floor slab 1, a cavity 23 is defined therebetween.
According to the structure, the utility model discloses the timber welding laminated wood floor assembly 100 of embodiment adopts 4 welding of timber to form concatenation floor 1 between the multilayer laminated wood 11, also adopts 4 welding of timber between tie-beam 2 and the concatenation floor 1, need not to adopt adhesive bonding in the whole connection process, consequently do not have free formaldehyde in the timber welding laminated wood floor assembly 100 of finally making, the feature of environmental protection is good, and it is quick to connect when 4 welding two wooden parts of timber, and the installation effectiveness is high. In addition, because the laminated timber 11 forms the spliced floor slab 1 by arranging a multilayer structure, the size of the spliced floor slab 1 is adjustable, and the spliced floor slab can adapt to different field installation conditions.
The wood nails 4, the laminated wood 11 required to be connected and the connecting beam 2 are all wood products, so that the joints of the wood nails 4 after welding are not easy to crack and deform, and the integrity is good. Need not to adopt metal connecting piece among the whole connection process, consequently there is not stress concentration that metal connecting piece's connection brought and the problem of junction easily warp and fracture for the timber welding lamination floor slab assembly 100 stable in structure can bear certain stress and not take place the fracture, as the substructure in timber structure house, life is of a specified duration.
The cavity 23 that forms between tie-beam 2 and concatenation floor 1 can be used to cross the line, makes things convenient for the later stage dowel welding laminated timber floor assembly 100 to use the line of walking behind the timber structure house, and it is easy to lay wire, beautifully just the security is high after the wiring.
The utility model discloses foretell timber welding lamination floor slab assembly 100 specifically can be used in the bottom sprag structure in timber structure house, also can directly be used to the ground in timber structure house.
It should be added here that, when the wooden nail 4 of the present invention is used for welding two wooden pieces, the following method can be used: the wooden nail 4 is loaded into an air gun and is driven into the air gun at the speed of 20-35 m/s. In the description of the present invention, "multi-layer" means two or more layers.
In some examples of the utility model, as shown in fig. 1, when concatenation floor 1 is folded by three-layer and above laminated timber 11, with multilayer laminated timber 11 along thickness direction in proper order called first layer 11a, second floor 11b, third layer 11c to last one deck 11n, first layer 11a superposes with second floor 11b and forms stable connection with the welding of dowel 4, third layer 11c superposes to second floor 11b and forms stable connection with the welding of dowel 4, analogize in proper order until last one deck 11n also superposes and forms stable connection by the welding of dowel 4. Therefore, the spliced floor slab 1 with three or more than three layers of laminated materials 11 is formed, the size and the paved area of the finally formed prefabricated wood nail welded laminated material floor slab assembly 100 are enlarged, the connection strength among the layers is enough, and cracking is not easy to form. It should be noted that, when the spliced floor slab 1 is formed by stacking three laminated materials 11, the last layer 11n is the third layer 11 c. In the description of the present invention, features defined as "first", "second" and "third" may explicitly or implicitly include one or more of the features for distinguishing between descriptive features, non-sequential, non-trivial and non-trivial.
Alternatively, as shown in fig. 1, a first offset distance L1 is formed between the nails 4 driven when connecting to the previous laminated material 11 and the nails 4 driven when connecting to the next laminated material 11 on the laminated material 11 in the middle layer. The first offset distance L1 is equal to or greater than 50 mm. When the wood nails 4 are adopted for welding between the two adjacent layers of laminated wood 11, the required number of the wood nails 4 is saved, the connection is tight, and the gaps in the length direction of the two connected layers of laminated wood 11 are few.
Alternatively, the studs 4 are driven between two layers of laminated timber 11 in a multi-row arrangement. The multi-row and aligned form facilitates the arrangement of the wooden nails 4 on the laminated timber 11.
Alternatively, the studs 4 are driven between two layers of laminated timber 11 in staggered rows. The staggered arrangement further reduces the probability that a gap can be formed between the connecting contact surfaces after the two laminated materials 11 are connected.
The distance between the wood nails 4 and the edge of the spliced floor slab 1 is not less than 20mm, and the distance between the wood nails 4 is 100-300 mm. It will be appreciated that the studs 4 are too close, for example less than 20mm, to the edge of the spliced floor 1, the ends of the spliced floor 1 are susceptible to increased cracking by the studs 4. If the wood nails 4 are arranged too close to each other, the wood nails 4 are wasted, the construction time is long, the number of connection points on the spliced floor slab 1 is too large, and the result of too concentrated stress is easily caused.
The utility model discloses an in some examples, as shown in fig. 1 and fig. 4, individual layer lamination material 11 is formed by two piece at least lamination material 11 concatenations, and individual layer lamination material 11 splices the department mutually and forms the concatenation seam, and the concatenation seam between the adjacent two-layer lamination material 11 staggers mutually, and the concatenation seam interval between the adjacent two-layer lamination material 11 is more than or equal to 600 mm. As shown in fig. 1, in a specific example, a plurality of laminated materials 11 to be spliced of an upper layer (e.g., a first layer 11a) are spliced along a length direction (referring to the length direction of the laminated materials) and a first seam 11a1 is formed at the spliced position; splicing a plurality of laminated materials 11 to be spliced of a next layer (such as the second layer 11b) along the length direction, forming a second joint 11b1 at the splicing position, superposing the plurality of laminated materials 11 of the next layer (the second layer 11b) on the plurality of laminated materials 11 of the previous layer (the first layer 11a) and driving the nails 4 for welding, and forming a second dislocation distance L2 between the first joint 11a1 and the second joint 11b1, wherein the second dislocation distance L2 is more than or equal to 600 mm. Therefore, the laminated timber 11 is spliced along the length direction thereof to form the nailed welded laminated timber floor assembly 100 having a larger dimension in the other direction.
When the distance between the splicing seams between the two laminated wood layers 11 is greater than or equal to 600mm, the beneficial effects are also explained by using a specific example: as described above, the first joint 11a1 and the second joint 11b1 are arranged in a staggered manner, after the first layer 11a and the second layer 11b are welded by the wooden nails 4 along the thickness direction of the laminated timber 11, the connection between the laminated timber 11 of the first layer 11a or between the laminated timber 11 of the second layer 11b is automatically formed without adding other connecting members at the first joint 11a1 and the second joint 11b1, so that not only is the connecting member required for connection saved, but also the construction time is saved. In addition, when the first joint 11a1 and the second joint 11b1 are arranged in a staggered manner, even if stress is transmitted from the first joint 11a1 to the second layer 11b along the thickness direction of the laminated material 11, the stress is not easy to expand backwards, and the stress is not easy to expand backwards, so that the finally manufactured wood nail welded laminated material floor slab assembly 100 is not only adjustable in size, but also high in structural strength, not easy to form a seam, and high in bearable stress.
Optionally, the distance between the first joint 11a1 and the second joint 11b1 and the edge of the spliced floor slab 1 is greater than or equal to 1000 mm. It can be understood that if the first joint 11a1 or the second joint 11b1 is too small from the edge of the spliced floor slab 1, the edge of the spliced floor slab 1 is easily cracked along the first joint 11a1 or the second joint 11b1 after being subjected to an external force, so that the laminated material is deformed at the first joint 11a1 or the second joint 11b 1. Therefore, the distance between the first joint 11a1 and the second joint 11b1 and the spliced floor slab 1 must be sufficient. That is to say, the end of the spliced floor slab 1 cannot be spliced along the length direction of the laminated timber 11 within 1000mm, and the two ends of the spliced floor slab 1 are not spliced within 1000 mm. Here, the ends of the spliced floor slabs 1 can be referred to fig. 1, i.e., both ends extending along the length direction of the laminated timber 11.
In some examples of the present invention, as shown in fig. 2 and 3, the tack welded laminated wood floor assembly 100 further comprises: the connecting plate 3, connecting plate 3 connect concatenation floor 1 and tie-beam 2 respectively, and connecting plate 3 adopts 4 weldings of dowel nail with concatenation floor 1 and tie-beam 2.

The I-beam has enough strength, and the I-beam can form a plurality of connecting surfaces for connecting a plurality of groups of spliced floor slabs 1. When the I-beam is connected at the end parts of a plurality of groups of spliced floor slabs 1, the formed timber welded laminated wood floor slab assembly 100 is not easy to disintegrate, and compared with the timber welded laminated wood floor slab assembly 100 which is formed by simply welding the laminated wood 11 by the timber 4 and has the same area, the timber welded laminated wood floor slab assembly 100 has a more stable structure and can be more suitable for the construction conditions on site.
In some specific examples, as shown in fig. 3, the side surfaces of the two flanges 21 parallel to the extending direction of the flanges 21 are both formed as the connecting surface 20, and when the connecting plate 3 is added, the outer surface of the connecting plate 3 is flush with the connecting surface 20 to jointly form a joint surface for jointing the floor slabs 1. In these embodiments, the connecting plate 3, the flanges 21 and the web 22 form a wire-passing cavity 23 therebetween.
Alternatively, as shown in fig. 2, the surfaces of the two flanges 21 facing each other form fitting grooves 211, respectively, and both ends of the web 22 are coupled in the fitting grooves 211, respectively. The fitting groove 211 forms a limit for the connection of the web 22, and the web 22 is not easily displaced after being connected to the fitting groove 211. In this example, in order to further enhance the positioning and connecting strength between the web 22 and the flange 21, the two are further connected by bolts or fixed by less glue.
Optionally, the flange 21 is made of wood, the web 22 is a metal plate, the web 22 made of metal greatly enhances the overall strength of the connecting beam 2, and after the connecting beam is connected with a plurality of spliced floor slabs 1, a stable wood nail welded laminated wood floor slab assembly 100 can be formed, so that the wood nail welded laminated wood floor slab assembly 100 is not easy to disintegrate.
