Description
Technical Field
The utility model belongs to the technical field of steel construction building house building component, concretely relates to gold alclad silver-colored steel constructs straw building component and building component of adjustable yardstick.
Background
The cold-formed thin-wall steel structure building system is characterized by light dead weight, good earthquake resistance, various connection forms, suitability for complex building modeling, less or no wet operation, suitability for factory optimization design and modular production, short construction period, flexible layout of house patterns, less construction waste, reusable components, near zero environmental pollution and the like, is more and more concerned by people and is listed as a preferred project in bottom-layer and medium-high-rise buildings. At present, the development and application of novel high-strength cold-bending section steel, especially thin-wall cold-bending section steel, have been popularized to a certain extent. However, the deep processing of the product components in the cold-bending thin-wall steel structure is insufficient in China, and the extensive part production and modular production are not achieved. The method is used to adopt a foreign forming technology, and the developed structure system with independent intellectual property rights is few and few, and is lack of independent brands. With the rapid development of new rural construction in recent years, the house demand of novel structures is continuously increased, the traditional concept is gradually changed, steel structure houses are gradually developed in rural areas, the existing steel structure house system structure is heavy, the construction period is long, the cost is high, and the popularization and the application are not facilitated. Especially, in recent years, after the environmental protection standard of engineering environment is improved, a lot of traditional steel structure building components combined with concrete are gradually reduced, after the traditional steel structure building components are built as frameworks, the components are generally poured with concrete, and spaces among the frameworks are filled in a building block or concrete filling mode to form wall bodies or floor support plates, and the filling materials have the advantages of self weight, low heat insulation performance, requirement of on-site pouring construction, setting time, low efficiency and poor construction environment and need to be improved. The construction speed and the construction efficiency are high due to the influence of environmental protection factors, and the construction method also becomes one of new construction requirements.
The inventor Weiqu et al proposed a "steel-wood type steel straw structural system" in 2016, 12, 30, and the patent application with publication No. CN106759905A is aimed at solving the problem of quick installation of the above patent, in which the structural form is formed by wrapping channel-shaped steel and straw compression core body, fixing by rivets and connecting by connecting holes. However, according to the practical process of utility model people, it is found that the combined building member of the channel-shaped steel and the compressed core body of the wrapped straw adopted in the patent document still has the problem of not strong enough bearing strength when being used as a beam or a column, especially when the combined building member can not be directly applied to a large-span beam member system, the stand column design is required to be added according to the acceptance strength, or the design of auxiliary members is required to be added, so that in practical application, the patent document is not applied to a large-scale composite structure system, and the application range and the popularization value are greatly limited.
The straw sawdust compact is a well-known mature product, is prepared by adding an adhesive, a hydrophobic agent, a flame retardant, a preservative and the like in the preparation process and pressing the mixture by large-ton-level pressure, has good integrity, moisture resistance, flame retardance, holding force, heat preservation and corrosion resistance, is compared with the existing concrete structure only in terms of compression resistance, and has the advantages of equivalent compression strength to the existing concrete structure, but in the aspect of practical application, the straw sawdust compact has lower tensile property and poor shear resistance, and is not suitable for large-span members. Although the above patent document adopts the channel-shaped steel and the wrapped straw compression core (similar to the straw wood chip compact), the strength of the whole building member can be improved to a certain extent by means of the tensile property of the channel-shaped steel, the channel-shaped steel and the straw compression core described in the patent document are not tightly combined and transmitted to the common resistance along the whole rod member and are coordinated with deformation, that is, other direct combination constraint relationship is not existed between the channel-shaped steel and the straw compression core except for the combination by the rivet. Therefore, when the building member is used for the upright post, the building member cannot bear external load with enough strength, and tests prove that after the pressure is increased, the groove-shaped steel can expand towards two sides, so that the wrapping constraint on the straw compression core body is lost, the stress concentration part in the middle of the straw compression core body is locally cracked, and the whole upright post is collapsed due to the fact that the external load is continuously increased. Meanwhile, when the building component is used as a beam system, the small span is not obviously uncomfortable, but the large span (more than 3 meters) is added with solid load to cause the integral bending phenomenon, and the further increase of the load can cause the bending of the local stress concentration area of the groove-shaped steel, thereby causing the local fracture of the straw compression core body. In the early development of the above patent literature technology, the complexity of the edge of the channel-shaped steel is increased, for example, a special-shaped structure is additionally arranged on the edge of the channel-shaped steel and is fixed by a middle cross bracing plate, but the method only depends on increasing the special-shaped edge of the channel-shaped steel to improve the strength of the whole building component, and practice proves that the scheme cannot be completely practical. Therefore, the utility model discloses the people further improves this technique through on above technical scheme basis to the realization is applied to in the building system with cold-formed thin wall shaped steel structure and straw saw-dust compacted body effectively combining.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Example 1: a prestressed gold-coated silver straw building component is shown in figure 1, wherein a first buckled C-shaped steel 201 and a second buckled C-shaped steel 202 form a columnar inner cavity, and a columnar straw wood chip compact 203 is matched and sleeved in the square column or cylindrical or hexagonal columnar inner cavity. Usually, the two side edges of the first C-shaped steel 201 and the second C-shaped steel 202 are not butted, and a fit clearance exists. Meanwhile, the two side edges of the first C-shaped steel 201 and the second C-shaped steel 202 are fixed with the straw wood chip compact 203 through the profile steel rivets to form a gold-coated silver assembly. As shown in fig. 2, end horizontal nodes 3a are sleeved on both ends of the gold-silver clad composite. The straw chip compacted body 203 is provided with a longitudinal perforation 204 along the length direction and a transverse perforation 205 along the width direction. Meanwhile, the prestressed longitudinal tie bars 4 penetrate through the longitudinal through holes 204 of the straw wood chip compacted body 203 along the length direction, the tail ends of the prestressed longitudinal tie bars 4 respectively penetrate through the corresponding end plate through holes 304 on the end transverse nodes 3a, two ends of the prestressed longitudinal tie bars 4 are respectively fixed through the prestressed locking nuts 8, and the prestressed locking nuts 8 are adjusted to enable the prestressed longitudinal tie bars 4 to have prestress.
In the embodiment, the straw wood chip compacted body is a brick section which is formed by pressing in a die through a large-tonnage press, a lacing wire hole for sleeving a prestress longitudinal lacing wire or a prestress transverse lacing wire is reserved in the brick section, or a corresponding abdicating hole is arranged at the end part of the brick section and used for installing a transverse node at the end part or a connecting nut and other necessary components. And after the whole construction system or the part of the construction system is finished, filling compressed straw particles into the redundant space of the corresponding abdicating hole (the bearing structure is established, and the rest space is basically not bearing force) to cast the construction body or fill other foam ceramsite prefabricated materials, wherein the foam ceramsite prefabricated materials are used for completely sealing the construction system, and the performances of heat insulation, flame retardance, hydrophobicity, sound insulation and the like are improved while the self tensile and compression bending bearing performance of the construction body is improved.
In this embodiment, the prestressed longitudinal tie bars 4 added at first can provide a prestressed pulling force, and form a repulsive force with the C-shaped steel and straw wood chip compacted bodies 203 on both sides, that is, a reaction force is formed between the pulling force of the prestressed longitudinal tie bars 4 and the C-shaped steel and straw wood chip compacted bodies 203 on both sides. In fact, the pulling force of the prestressed longitudinal tie bar 4 mainly acts on the straw wood chip compacted body 203 through the end transverse joints 3a at the two ends and then acts on the C-shaped steel. Therefore, the load-bearing performance of the building element is not completely dependent on the tensile strength of the C-shaped steel, but depends on the tensile strength of the combined stress, but from the aspect of the tensile strength of the building element, the prestressed longitudinal tie bars 4 can provide strong tensile performance because the prestressed tensile force is applied in advance, and the deformation of the building element and the straw wood chip compacted body 203 inside the building element can be eliminated by the longitudinal prestress before deformation.
On the basis, the prestressed transverse tie bars 5 penetrate through the transverse through holes 205 of the straw wood chip compacted body 203 and then respectively penetrate through the corresponding section steel through holes 206 on the side surfaces of the first C-section steel 201 and the second C-section steel 202, two ends of the prestressed transverse tie bars 5 are respectively fixed through the prestressed locking nuts 8, and the prestressed locking nuts 8 are adjusted to enable the prestressed transverse tie bars 5 to have prestress. Through addding horizontal lacing wire 5 of prestressing force and can not making both sides C shaped steel and the straw saw-dust compact 203 at middle part pass through pressure connection together, can ensure moreover that straw saw-dust compact 203 self has prestressing force along the horizontal for the vertical lacing wire 4 of countermeasures prestressing force can overcome the straw saw-dust compact 203 through horizontal prestressing force promptly and open, thereby prevent that the straw saw-dust compact 203 from warping (by horizontal prestressing force elimination this deformation possibility before warping). Thus, the shear resistance can be improved.
On the other hand, due to the prestress pressing and wrapping effect of the C-shaped steel on the two sides on the straw sawdust compacted body 203, the straw sawdust compacted body 203 can guarantee an even stress state, and the problem that the whole building component is collapsed due to damage caused by local stress concentration finally does not occur. Thus, the shear resistance can be improved. The transverse prestress tension on the C-shaped steel on both sides of the building element can be changed in distribution according to load distribution, for example, the transverse prestress tension is usually added in the middle of the building element to improve the shearing resistance of the middle of the building element.
