Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a heat insulation structure of a structural column. Background Art

[0002] The building envelope system is a crucial component of a building. Its primary function is to climatically separate the building's internal use spaces from the external environment, maintaining a stable indoor climate. The building envelope typically utilizes lightweight materials with low heat transfer coefficients to reduce heat exchange between the building's interior and exterior. Certain areas within the building envelope have a higher heat transfer coefficient than adjacent areas, making them more susceptible to heat transfer between the building's interior and exterior, hence the term "thermal bridge." Within this thermal bridge area, the indoor temperature is significantly higher than other areas in the summer and significantly lower in the winter, making condensation and frosting highly likely to occur. This, in the long term, reduces the durability of local building components and impacts the proper use of the building's interior. Furthermore, from the perspective of overall building energy consumption, even when the building's overall thermal performance is good, thermal bridges can become significant windows for heat transfer between indoor and outdoor spaces, reducing the building's overall insulation capacity and increasing energy consumption. Masonry is a simple and reliable building structural system, widely used in one- and two-story houses, particularly in rural construction, due to its low cost and rapid construction.

[0003] The blocks widely used at present are all lightweight, high-strength thermal insulation materials with low thermal conductivity. However, the structural columns in the masonry structure are reinforced concrete columns, which have a significantly higher thermal conductivity than the masonry structure. They are extremely likely to become thermal bridges in the masonry structure, causing indoor walls to mold and fall off, reducing the overall comfort of the building's indoor environment.

[0004] The patent document with application number 202211404429.8 provides a structural column thermal insulation structure, in which an insulation board is arranged between a pair of structural column steel cages to block the thermal bridge effect.

[0005] However, in the above structure, the connection between the cast concrete structural columns and the adjacent blocks is relatively weak, and the integrity between the concrete structural columns and the adjacent blocks needs to be strengthened. Utility Model Content

[0006] In view of this, the utility model provides a structural column heat insulation structure, the main purpose of which is to improve the firmness of the connection between the concrete structural column and the adjacent blocks.

[0007] In order to achieve the above-mentioned purpose, the present invention mainly provides the following technical solutions:

[0008] The utility model provides a heat-insulating structure for a structural column, which comprises a spacer, a structural column reinforcement cage and a heat-insulating layer;

[0009] The gap is formed between two adjacent block walls, the portion of the gap close to the interior is a first space, and the portion of the gap close to the exterior is a second space. A plurality of first protrusions are sequentially arranged on opposing blocks in the first space, and a plurality of second protrusions are sequentially arranged on opposing blocks in the second space. There is a gap between the second protrusions and the inner side surface of the second space.

[0010] The structural column reinforcement cage is arranged in the first space;

[0011] The heat-insulating layer is filled in the second space, and a notch is provided on the outer surface of the heat-insulating layer. The notch and the second protrusion cooperate with each other.

[0012] The purpose of the present invention and the solution to its technical problems can be further achieved by adopting the following technical measures.

[0013] Optionally, the upper end surface of the first protrusion is a plane, and the lower end surface of the first protrusion is an inclined surface.

[0014] Optionally, the second protrusion is a right-angled triangular prism, and the triangular hypotenuse of the right-angled triangular prism is close to the inner side surface of the second space.

[0015] Optionally, the first protrusion and the second protrusion are staggered with each other in the vertical direction.

[0016] Optionally, the inclination angle of the inclined surface is 45°.

[0017] Optionally, the thickness of the insulation layer is 100 mm.

[0018] Optionally, a plurality of anchor rods are further included, one end of each anchor rod being located outside the insulation layer, and the other end of each anchor rod passing through the insulation layer and connected to the structural column reinforcement cage.

[0019] By means of the above technical solution, the present invention has at least the following advantages:

[0020] When constructing the heat insulation structure of the structural column, the structural column steel cage is placed in the first space, and the bottom and top of the structural column steel cage are connected to the beams and slabs by embedding reinforcement.

[0021] Since the adjacent block walls are self-insulating aerated concrete block walls, the insulation layer is reinforced with an integrated insulation board with the same thermal coefficient as the self-insulating blocks. The structural column reinforcement cage is tied. The inner formwork of the first space is made of bamboo plywood and 50×100 wooden squares and reinforced with steel pipe fasteners. The outer surface recess of the insulation layer and the second protrusion in the second space cooperate with each other, so the insulation layer is not easy to detach from the outside of the wall.

[0022] A 200mm high notch is reserved at the top of the inner formwork to facilitate concrete pouring.

[0023] After the above process, when the concrete structural column is cast, the multiple first protrusions are embedded in the relative surfaces of the concrete structural column, and the multiple recesses on the outer surface of the insulation layer and the multiple second protrusions cooperate with each other, so that the insulation layer will not separate from the outside of the wall. Through the above structure, while eliminating the thermal bridge effect, the firmness of the connection between the concrete structural column and the adjacent block wall is improved.

[0029] To further illustrate the technical means and effects employed by this utility model to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, provides a detailed description of the specific implementation methods, structures, features, and effects of this utility model application. In the following description, different references to "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0030] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 4 As shown, an embodiment of the present invention provides a heat insulation structure of a structural column, which includes: a spacer, a structural column reinforcement cage 4 and an insulation layer 5;

[0032] The interval is formed between two adjacent block walls 1, the portion of the interval close to the interior is a first space, and the portion of the interval close to the exterior is a second space. A plurality of first protrusions 2 are sequentially arranged on the opposing block surfaces in the first space, and a plurality of second protrusions 3 are sequentially arranged on the opposing block surfaces in the second space. There is a gap between the second protrusions 3 and the inner side surface of the second space.

[0033] The structural column reinforcement cage 4 is arranged in the first space;

[0034] The thermal insulation layer 5 is filled in the second space. A notch 6 is provided on the outer surface of the thermal insulation layer 5 . The notch 6 and the second protrusion 3 cooperate with each other.

[0035] The working process of the structural column thermal insulation structure is as follows:

[0036] When constructing the heat insulation structure of the structural column, the structural column reinforcement cage 4 is placed in the first space, and the bottom and upper ends of the structural column reinforcement cage 4 are connected to the beams and plates by adopting the method of planting reinforcement.

[0037] Since the adjacent block wall 1 is a self-insulating aerated concrete block wall 1, the insulation layer 5 is reinforced with an integrated insulation board with the same thermal coefficient as the self-insulating block, the structural column steel cage 4 is tied, and the inner formwork of the first space is made of bamboo plywood and 50×100 wooden squares, and reinforced with steel pipe fasteners. In the second space, the outer surface recess 6 of the insulation layer 5 and the second protrusion 3 cooperate with each other, and the insulation layer 5 is not easy to detach from the outside of the wall.

[0038] A 200mm high notch is reserved at the top of the inner formwork to facilitate concrete pouring.

[0039] After the above process, when the concrete structural column is cast and vibrated, the multiple first protrusions 2 are embedded in the relative surfaces of the concrete structural column, and the multiple recesses 6 on the outer surface of the insulation layer 5 and the multiple second protrusions 3 cooperate with each other, so that the insulation layer 5 will not separate from the outside of the wall. Through the above structure, while eliminating the thermal bridge effect, the firmness of the connection between the concrete structural column and the adjacent block wall 1 is improved.

[0040] Specifically, the first protrusion 2 and the self-insulating aerated concrete block are integrally formed, and the second protrusion 3 and the self-insulating aerated concrete block are integrally formed.

[0041] In a specific embodiment, the upper end surface of the first protrusion 2 is a plane, and the lower end surface of the first protrusion 2 is an inclined surface.

[0042] In this embodiment, specifically, when pouring the concrete structural column, the upper end plane of the first protrusion 2 plays a bearing role on the concrete above it, and at the same time, the concrete also slides down along the inclined surface of the lower end of the first protrusion 2, which makes it easier for the concrete to fully fill the space below the first protrusion 2, thereby ensuring the density of the concrete structural column pouring.

[0043] In a specific embodiment, the second protrusion 3 is a right triangular prism, and the triangular hypotenuse of the right triangular prism is close to the inner side of the second space.

[0044] In this embodiment, specifically, the horizontal cross-section of the right triangular prism is a right triangle, and the triangular hypotenuse of the right triangular prism faces the inner side surface of the second space, so that a larger distance can be maintained between the second protrusion 3 and the inner side surface of the second space. After the recess 6 of the thermal insulation layer 5 fits the second protrusion 3, the thermal insulation layer 5 can maintain a larger thickness, which is beneficial to thermal insulation.

[0045] In a specific embodiment, the first protrusion 2 and the second protrusion 3 are staggered with each other in the vertical direction.

[0046] In this embodiment, specifically, after the recess 6 of the insulation layer 5 and the second protrusion 3 are fitted into each other, the insulation layer 5 between the two upper and lower adjacent second protrusions 3 is thicker, which can provide better lateral support for the inner concrete and avoid leakage.

[0047] In a specific embodiment, the inclination angle of the inclined surface is 45°.

[0048] In this embodiment, specifically, an inclination angle of 45° is adopted, and with concrete vibration, the concrete settles along the lower end surface of the first protrusion 2 and spreads horizontally, which can quickly fill the space below the first protrusion 2.

[0049] In a specific embodiment, the thickness of the thermal insulation layer 5 is 100 mm.

[0050] In this embodiment, specifically, the 100 mm insulation layer 5 blocks the heat transfer inside and outside the wall at the structural column position, avoiding the thermal bridge effect.

[0051] In a specific embodiment, a plurality of anchor rods 7 are further included, one end of each anchor rod 7 is located outside the insulation layer 5 , and the other end passes through the insulation layer 5 and is connected to the structural column reinforcement cage 4 .

[0052] In this embodiment, specifically, on the basis of the original insulation layer 5 fixing structure, multiple anchor rods 7 further fix the insulation layer 5, wherein the installation holes of the anchor rods 7 should be no less than 50 mm away from the edge of the insulation layer 5 and be evenly arranged, the hole spacing should not be greater than 550 mm, and the effective anchoring length of the anchor rods 7 in the concrete should not be less than 50 mm.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
