Description

Technical Field

[0001] This utility model relates to the field of cultural relic building protection and construction technology, specifically to a temporary sealing device for door and window openings of cultural relic buildings. Background Technology

[0002] In the relocation of historical buildings, the openings of doors and windows are structurally weak points. If they are not temporarily sealed, they are prone to cracking of walls and displacement of components due to horizontal forces and vibrations during the lifting and relocation process, which will affect the overall stability of the building. At the same time, the protection of historical buildings requires that temporary measures should not cause irreversible damage to the original structure and should meet the principle of reversibility of "removable and without residue".

[0003] The existing temporary sealing methods have the following problems: 1. Risk of damage due to rigid connection: Ordinary brick masonry is directly built with the original structure without isolation measures. When removing it, the masonry needs to be broken, which can easily scratch and damage the surface of the original wall or door frame components; 2. Insufficient integrity: Temporary sealing materials such as wood boards and color steel plates have low rigidity and cannot resist lateral forces during translation, which can easily lead to deformation and displacement, thus losing their protective function; 3. Poor material compatibility: Some sealing materials have large differences in shrinkage rate with the original structural materials, which can easily cause cracks, and the residual mortar is difficult to clean after removal.

[0024] See Figures 1-3 This utility model provides a temporary sealing device for the openings of doors and windows in a cultural relic building, used for temporarily sealing the openings of doors and windows in a cultural relic building 6. It includes a sealing body 1 and an isolation layer. The isolation layer is wrapped around the inner wall of the opening. The sealing body 1 is located inside the opening, and each side wall of the sealing body 1 facing the opening contacts the corresponding part of the isolation layer.

[0025] In this embodiment, the sealing device mainly provides strength support for the door and window openings through the sealing body 1, which constitutes the basic support system of the sealing device. This achieves pressure resistance in all directions during the movement of the cultural relic building 6, preventing cracking and deformation at the door and window openings. Furthermore, the sealing body 1 does not directly contact the side walls of the door and window openings, but rather indirectly abuts against them through an isolation layer. In other words, the isolation layer prevents the sealing body 1 from directly contacting the side walls of the door and window openings, thus preventing scratches and damage to the side walls of the door and window openings when the sealing body 1 is removed, and maintaining the original structural appearance of the cultural relic building 6.

[0026] Optionally, the sealing body 1 includes multiple aerated concrete blocks, which are constructed by arranging the multiple aerated concrete blocks in a "one header, one stretcher" pattern to form the sealing body 1.

[0027] In this embodiment, the sealing body 1 is constructed from multiple aerated concrete blocks. Specifically, 200mm thick aerated concrete blocks can be used in conjunction with DM5 grade cement mortar to form a stable sealing system. The compressive and shear resistance meets the requirements of horizontal force and vibration load during the translation of the cultural relic building 6, thus avoiding cracking caused by uneven stress on the original structure at the door and window openings.

[0028] Among them, as the unit component constituting the main body 1 of the sealing, the aerated concrete blocks can be A5 grade aerated concrete blocks with a dry density ≤600kg / m³, compressive strength ≥3MPa, and dimensional deviation ≤±2mm, to ensure the flatness of the masonry and the stability of the structure; DM5 grade cement mortar is used for the bonding of the blocks, and can be prepared by using P.O42.5 cement and medium sand (fineness modulus 2.3-3.0) with a mix ratio of cement:sand = 1:5 (mass ratio), and the consistency is controlled at 50-70mm, taking into account both bonding strength and removability.

[0029] In addition, the sealing device can achieve reversible restoration: the isolation layer isolates the sealing masonry from the original structure, and there is no need to break the sealing body 1 when removing it. The masonry blocks can be separated by manual prying, and then the isolation layer can be peeled off. There is no mortar residue or scratch damage on the surface of the original structure.

[0030] In addition, it can also be adapted to the characteristics of cultural heritage buildings: due to the low density of aerated concrete blocks (≤600kg / m³), the additional load on the original structure is small, and the sound absorption and heat insulation performance is excellent, which can reduce the impact of construction vibration and changes in ambient temperature on other components of cultural heritage buildings (such as wooden doors and windows, murals).

[0031] See Figure 1-3 Optionally, the isolation layer includes a plastic film isolation layer 2 and a filling cotton 4. The plastic film isolation layer 2 is laid on at least the bottom side wall, left side wall and right side wall of the door and window opening, and the filling cotton 4 is filled at least between the sealing body 1 and the top side wall of the door and window opening.

[0032] In this embodiment, specifically, the isolation layer includes a plastic film isolation layer 2 and filling cotton 4. The plastic film isolation layer 2 can be made of polyethylene material with a thickness of 0.1-0.15mm, and has aging resistance and tear resistance properties. When laying it, first clean the surface of the original structure (i.e., the side walls of the door and window openings) of floating dust and loose particles, and then use a neutral adhesive (such as starch glue) to locally fix the plastic film isolation layer 2 to prevent displacement.

[0033] In addition, the filling cotton 4 can be made of flame-retardant glass wool with a thermal conductivity ≤0.04W / (m). K), and has a buffering effect, which can absorb the slight relative displacement between the sealing main body 1 and the original structure during the translation of cultural relic building 6, and avoid hard contact damage.

[0034] Optionally, a portion of the plastic film isolation layer 2 extends to the inner and outer sides of the cultural relic building 6, wherein the direction between the inner and outer sides of the cultural relic building 6 is the through direction of the door and window openings.

[0035] In this embodiment, the plastic film isolation layer 2 extends forward and backward by a certain length, for example, 50mm, which can ensure that the mortar will not come into contact with the original structure at all when the aerated concrete blocks are laid.

[0036] Optionally, the thickness of the filling cotton 4 is 20mm-30mm, and the compression rate of the filling cotton 4 is 30%-50%.

[0037] In this embodiment, the filling cotton 4 can be made of flame-retardant glass wool with a thickness of 20mm-30mm and a compression rate of 30%-50%. The thickness of 20mm-30mm is key to thermal insulation, forming an effective insulation layer, reducing heat transfer between the inside and outside of the building, and meeting energy-saving requirements; the compression rate of 30%-50% makes the cotton filling more compact, avoiding gaps and ensuring that the thermal insulation effect is not compromised.

[0038] See Figure 1-3 Optionally, the sealing device also includes an anti-detachment structure, which is disposed on both sides of the inner side of the cultural relic building 6 to restrict the movement of the sealing body 1.

[0039] In this embodiment, the anti-detachment structure can enhance the stability of the temporary connection between the sealing device and the original structure, and prevent the block from shifting during the translation process.

[0040] See Figure 1-3 Optionally, the anti-detachment structure includes an outer blocking member 3, an inner blocking member 5, and fasteners. The inner blocking member 5 is located inside the cultural relic building 6, and the inner blocking member 5 abuts against the sealing body 1 and the cultural relic building 6 respectively. The outer blocking member 3 is located on the outside of the cultural relic building 6, and the outer blocking member 3 abuts against the sealing body 1 and the cultural relic building 6 respectively. The inner blocking member 5 is connected and fixed to the corresponding outer blocking member 3 by the fastener.

[0041] In this embodiment, the outer blocking member 3 is located on the inner side of the cultural relic building 6, and the inner blocking member 5 is located on the inner side of the building. When the blocking members are in contact with the sealing body 1 and the original structure (cultural relic building 6) respectively, the sealing structure can be prevented from shifting inward or outward by fasteners after the corresponding blocking members on the inner and outer sides are connected and fixed.

[0042] See Figure 1-3Optionally, there are two inner blocking members 5 and two outer blocking members 3. The two inner blocking members 5 are located at the left and right ends of the inner side of the sealing body 1, and the two outer blocking members 3 are located at the left and right ends of the outer side of the sealing body 1.

[0043] In this embodiment, two inner blocking members 5 are provided on the inner side of the cultural relic building 6, and two outer blocking members 3 are provided on the outer side. That is, one inner blocking member 5 is arranged between the inner left end of the sealing body 1 and the cultural relic building 6, and between the inner right end of the sealing body 1 and the cultural relic building 6. One outer blocking member 3 is arranged between the outer left end of the sealing body 1 and the cultural relic building 6, and between the outer right end of the sealing body 1 and the cultural relic building 6. After the corresponding inner blocking members are connected by fasteners, the stability of the sealing body 1 can be further improved and its displacement can be prevented.

[0044] Optionally, the fastener is a tie rod; and / or, the outer blocking member 3 and the inner blocking member 5 are both channel steel.

[0045] In this embodiment, the fastener can be a tie rod, which is a commonly used connector in building construction. Its core function is to "tighten the inner and outer blocking components in both directions to ensure the precise positioning of the sealing body 1". Each blocking component can be a channel steel, specifically a U-shaped channel steel. The U-shaped opening of each channel steel is away from the sealing body 1 to facilitate assembly with the tie rod.

[0046] It should be noted that during the assembly of the tie rod, it is necessary to ensure that it does not damage the original structure. It is permissible to damage the sealing body 1, for example, by having the screw in the tie rod pass through the sealing body 1.

[0047] In summary, the construction steps for this sealing device can be as follows: Cleaning and pretreatment of the original structure: Clean the side walls of the six doors and windows of the cultural relic building and the surrounding area of ​​the floating dust, loose mortar and dirt. For the damaged parts of the original structure (such as missing brick corners and surface cracks), use lime mortar to make local repairs. After repair, the surface flatness is ≤5mm. Plastic film isolation layer 2 installation: Cut plastic film to match the size of the door and window opening (extending 50mm beyond the edge of the opening), evenly apply a thin layer of neutral adhesive (coating thickness ≤0.5mm) to the contact surface between the original structure and the sealing area, lay the plastic film isolation layer 2 flat, wrap it around the left side wall, right side wall and bottom side wall of the door and window opening, remove air bubbles with a scraper to ensure that the film adheres to the original structure, and the edges can be temporarily fixed with pressure strips; Aerated concrete block masonry: The “one stretcher and one header” masonry method is adopted. 200mm thick aerated concrete blocks are laid with DM5 grade cement mortar. The mortar joint thickness is controlled at 8-12mm. The flatness is checked with a level after every 3 courses of blocks are laid. The verticality deviation is ≤3mm / m. Channel steel installation: After the wall is built, channel steel is installed on both the inner and outer sides of the masonry as a blocking component. The channel steel on both the inner and outer sides is connected by tie rods. The surface of the channel steel is set in the center along the joint between the original structure and the temporary sealing masonry, and overlaps with the structure on both sides. Gap treatment and maintenance: When the masonry reaches the top of the door and window openings, leave a 20-30mm gap, fill it with filler cotton 4, cut the filler cotton 4 into strips that match the gap size, compress it and embed it; after the masonry is completed, spray water to cure the sealing device, the curing cycle is ≥7 days, and avoid collisions and vibrations during the curing period; Acceptance and dismantling: Before the relocation construction, test the compressive strength and shear strength of the sealing device to confirm that it meets the requirements; after the relocation is completed, when dismantling, first use a pry bar to pry along the plastic film isolation layer 2 to separate the blocks from the original structure, then remove the blocks one by one, clean the plastic film isolation layer 2 and residual mortar (use a soft brush to clean the residual mortar, and do not use sharp tools), and restore the appearance of the original structure.
