Description

Technical Field

[0001] This invention relates to the field of building exterior wall construction technology, specifically to a joint structure and construction method for prefabricated building insulation boards and fixing components. Background Technology

[0002] In the existing technology, the cutting of insulation boards at the reserved holes in the wall is very arbitrary. The area of ​​the cut holes on the insulation boards is much larger than the size of the fixed components, and there is a misalignment with the installation position of the components. Furthermore, there are no effective remedial measures for the cut holes, which will create a large number of cold bridges. This will affect the airtightness, thermal insulation effect, and waterproof performance of the exterior wall panels. Summary of the Invention

[0003] The purpose of this invention is to provide a joint structure and construction method for prefabricated building insulation boards and fixing components, which solves the problem that the lack of effective remedial measures for the cut holes on the insulation boards will lead to a large number of cold bridges.

[0004] This invention solves the above-mentioned technical problems through the following technical solution: the joint structure of this invention is set inside the cut hole of the insulation board to seal and fill the cut hole; it includes an installation structure, a grout cavity, four inner sealing elements, and four outer sealing elements; wherein:

[0005] The slurry cavity is horizontally opened within the installation structure. A through-hole is vertically opened in the middle of the installation structure. Four inner sealing elements are arranged around the installation through-hole, and their outer peripheries are slidably inserted into the inner side of the slurry cavity. The four inner sealing elements are used to seal the installation through-hole and to fit tightly with the fixing components.

[0006] The four outer sealing elements are slidably inserted into the outer side of the slurry cavity, and the four outer sealing elements seal and enclose the cavity.

[0007] The installation structure has a grouting hole that communicates with the grout cavity. Grout is injected into the grout cavity through the grouting hole. The grout squeezes the four outer seals outward and makes them adaptively seal against the side wall corresponding to the cutting hole.

[0008] Preferably, the installation structure consists of two partitions and a column connected and fixed between the two partitions, with the gap between the two partitions forming a slurry cavity.

[0009] Preferably, the inner sealing element includes an isolation block, an arc-shaped sealing block is fixed inside the isolation block, an arc-shaped groove is opened on the upper side of the isolation block, and a locking structure is slidably arranged in the arc-shaped groove. The four locking structures slide in the same direction. When the two ends of one locking structure are respectively located in the arc-shaped groove of the adjacent isolation block, the four inner sealing elements can block the installation through hole.

[0010] Preferably, the locking structure includes an arc-shaped locking block that is slidably disposed in an arc-shaped groove, and a push block is fixed on the upper side of the arc-shaped locking block.

[0011] Preferably, the arc-shaped sealing block is made of soft rubber or sponge.

[0012] Preferably, the outer sealing element includes an L-shaped slider, and two adjacent L-shaped sliders are sealed together by an extension structure. An outer sealing block is fixed to the outside of the L-shaped slider, and the outer sealing blocks of two diagonally arranged L-shaped sliders are located on the same plane.

[0013] The outer sealing block is L-shaped, and two outer sealing blocks located on the same plane enclose a frame structure.

[0014] Preferably, the vertical cross-sections of the outer sidewall of the outer sealing block and the inner sidewall of the cutting hole are interlocking concave-convex structures.

[0015] Preferably, the extended structure includes elongated inner cavities at both ends of the L-shaped slider, with a partition plate rotatably mounted inside the elongated inner cavity, and a spring installed inside the elongated inner cavity to provide rotational force to the partition plate. The partition plate extends into the elongated inner cavity of the adjacent L-shaped slider to ensure that the two partition plates always remain in contact.

[0016] Preferably, the thickness of the isolation block and the L-shaped slider are adapted to the height of the slurry cavity.

[0017] This invention also proposes a construction method for the joint structure of the prefabricated building insulation board and the fixing component described above, comprising the following steps:

[0018] Step 1: Preliminary installation: Insert the joint structure into the cut hole of the insulation board, and ensure that the fixing components pass through the installation through hole;

[0019] Step 2: Tighten the inner seals: Press the four inner seals against the fixed component so that the four inner seals seal and surround the fixed component. At the same time, push the four locking structures in the same direction to slide in the arc groove so that one end of the locking structure extends into the arc groove of the adjacent locking structure.

[0020] Step 3: Filling with grout: Inject grout into the grout cavity through the grouting hole. The pressure of the grout will push the four outer seals outward until the outer sealing block of each outer seal is in close contact with the four side walls of the cutting hole.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. This invention can fill and seal the gap between the fixed component and the cutting hole. Even if the position of the insulation board and the fixed component is offset, the four inner sealing components can adaptively seal with the fixed component at any position. The cooperation of the four outer sealing components can adapt to the size of the cutting hole, thus sealing and filling the cutting hole.

[0023] 2. The concave-convex structure not only increases the stability of the connection between the insulation board and the external sealing component, but also prevents the formation of thermal bridges between the insulation board and the external sealing component. It also makes the connection between the pre-drilled steel rod component and the insulation board tighter, thus improving the insulation, airtightness, thermal insulation and waterproofness of the building.

Detailed Implementation

[0032] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] This embodiment provides a technical solution: a joint structure for prefabricated building insulation boards and fixing components, such as... Figure 1-6As shown, the joint structure is set inside the cut hole of the insulation board to seal and fill the cut hole. The cut hole is cut into a rectangular shape. During installation, the fixing component passes through the cut hole. The cross-section of the fixing component is a circular structure. This joint structure includes an installation structure 1, a grout cavity 2, four inner sealing elements, and four outer sealing elements.

[0035] The installation structure 1 consists of two partitions and four columns 11 that are fixed between the two partitions. The columns 11 are fixed to the two partitions by screws, and the gap between the two partitions forms the slurry cavity 2.

[0036] A through-hole is vertically opened in the middle of the mounting structure 1. The mounting hole can be rectangular or circular. Four inner seals are arranged in the mounting hole, and their outer edges are slidably inserted into the inner side of the slurry cavity 2. The four inner seals can move freely in the mounting hole (the outer edges of the inner seals will never leave the slurry cavity 2). That is, when the position of the fixing component and the insulation board is offset, the offset between the fixing component and the insulation board can be eliminated by moving the four inner seals to seal and surround the fixing component. In other words, by sealing the mounting hole and tightly fitting with the fixing component, the thermal bridge on the outer edge of the fixing component is blocked.

[0037] In this embodiment, the inner sealing element includes an isolation block 54, with the two sides of the isolation block 54 set at a 45° angle to ensure a tight splicing between four adjacent isolation blocks 54. An arc-shaped sealing block 51 is fixed inside the isolation block 54. The arc-shaped sealing block 51 is made of soft rubber or sponge. The soft rubber or sponge can deform under force to ensure a tight seal with the fixed component.

[0038] An arc-shaped groove 55 is provided on the upper side of the isolation block 54. The radius and position of the multiple arc-shaped grooves 55 are matched. A locking structure is slidably provided in the arc-shaped groove 55. When the four locking structures slide in the same direction, and the two ends of one locking structure are respectively located in the arc-shaped groove 55 of the adjacent isolation block 54, the displacement of the inner sealing element can be restricted, so as to achieve the sealing of the installation through hole by the four inner sealing elements and the tight cooperation with the fixed component.

[0039] The locking structure includes an arc-shaped locking block 52 that is slidably disposed in an arc-shaped groove 55. A push block 53 is fixed on the upper side of the arc-shaped locking block 52. The arc-shaped locking block 52 can be pushed to slide along the arc-shaped groove 55 by the push block 53. The height of the push block 53 is higher than the upper surface of the mounting structure 1 to facilitate user operation.

[0040] Four external sealing elements are slidably inserted into the outside of the slurry inner cavity 2, and the four external sealing elements seal and enclose the cavity. The external sealing elements include L-shaped sliders 3. The two adjacent L-shaped sliders 3 are sealed and connected by an expansion structure to ensure the sealing between the two adjacent L-shaped sliders 3. An external sealing block 4 is fixed on the outside of the L-shaped slider 3. The external sealing blocks 4 in the two diagonally arranged L-shaped sliders 3 are located on the same plane. Since the rectangle has two pairs of diagonals, there are two layers of external sealing blocks 4, forming two seals.

[0041] The outer sealing block 4 is L-shaped, and two outer sealing blocks 4 located on the same plane enclose a frame structure. The vertical cross-section of the outer side wall of the outer sealing block 4 and the inner side wall of the cutting hole is a convex-concave structure that interlocks with each other. The convex-concave structure increases the stability of the connection between the insulation board and the outer sealing component, and prevents the generation of thermal bridges between the insulation board and the outer sealing component. It also makes the connection between the reserved hole steel rod component and the insulation board tighter, thereby improving the insulation, airtightness, thermal insulation and waterproofness of the building.

[0042] The extended structure includes elongated inner cavities 31 at both ends of the L-shaped slider 3. A partition plate 32 is rotatably installed in the elongated inner cavity 31. The inner end of the partition plate 32 is located at the bottom of the elongated inner cavity 31, and its turning point is located at the end of the partition plate 32. A spring 33 is installed in the elongated inner cavity 31 to give the partition plate 32 a rotational force. The partition plate 32 extends into the elongated inner cavity 31 of the adjacent L-shaped slider 3. The partition plates 32 in the two opposing elongated inner cavities 31 rotate towards each other due to the force of the spring 33, so as to ensure that the two partition plates 32 always keep in contact. The thickness of the partition block 54, the L-shaped slider 3, and the partition plate 32 are all adapted to the height of the slurry inner cavity 2 to ensure sealing.

[0043] The installation structure 1 has grouting holes 12 that communicate with the grout cavity 2. The number of grouting holes 12 can be 1-4, depending on the needs. Grout is injected into the grout cavity 2 through the grouting holes 12. The grout squeezes the four outer sealing parts outward and makes them adapt to the sealing contact with the side wall corresponding to the cutting hole. This adapts to the positional deviation between the insulation board and the fixed component and the problems caused by it.

[0044] Example 2

[0045] One embodiment of the construction method for the joint structure of prefabricated building insulation panels and fixed components, such as... Figure 1-6 As shown, it includes the following steps:

[0046] Step 1: Preliminary installation: Place the joint structure into the cut hole of the insulation board, and ensure the approximate position of the installation structure 1, and that the fixing component passes through the installation through hole. At this time, the four inner seals need to be moved to the outside of the installation through hole to prevent interference with the fixing component.

[0047] Step 2: Tighten the inner seals: Press the four inner seals against the fixed component so that the four inner seals seal and surround the fixed component. The isolation blocks 54 of the four inner seals are tightly spliced ​​to block the installation through hole. At the same time, push the four locking structures in the same direction to slide in the arc groove 55 so that one end of the locking structure extends into the arc groove 55 of the adjacent locking structure, thereby locking and fixing the four adjacent isolation blocks 54.

[0048] Step 3: Filling with grout: Inject grout into the grout cavity 2 through the grouting hole 12. The grout can be cement grout. The pressure of the grout will push the four outer seals outward. The length of the two isolation plates 32 in the extended structure needs to be set to a certain length. Due to the force of the spring 33, the two isolation plates 32 are kept in contact at all times to prevent the grout from overflowing into the grout cavity 2. The grout filling makes the outer sealing block 4 of each outer seal in close contact with the four side walls of the cutting hole, thereby achieving the filling and sealing of the gap between the fixed component and the cutting hole through this joint structure.

[0049] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
