Description

Technical Field

[0001] The invention belongs to the field of strip board inner partition wall door opening structure, and in particular relates to a strip board inner partition wall door opening structure and an inner partition wall. Background Art

[0002] When installing the stripboard inner partition wall, the door opening is one of the important nodes. The existing stripboard inner partition wall door opening structure is to splice the door headboard at the inner corner of the door opening. Due to the frequent opening and closing of the door, the horizontal and vertical joints at the inner corner of the upper part of the door opening are prone to cracking. Therefore, special construction treatment is required when installing and building the door opening. According to market research, the current existing construction operations often use the following solutions to solve the problem of door opening cracking. Generally, the door opening of the room is set at a corner of the room close to the adjacent wall or structural column, and the distance from the adjacent wall or structural column is about 20 cm. This is to allow the door body to stop as close to the corner as possible after opening, so as to improve the space utilization rate of the passage and room.

[0003] Solution 1: Cut existing interior partition wall strips to make door frame uprights; process stoppers on existing interior partition wall strips to make door frame uprights; cut existing lightweight interior partition wall strips to corresponding lengths to make door headboards; overlap the ends of the door headboard on the stoppers of the door frame uprights and door frame uprights to form a door opening, and form an inner corner position A at the upper joint of the door opening. The joint at the inner corner position A is prone to cracking, please refer to 26. The above-mentioned on-site cut door head panels, door frame uprights and door frame columns have larger geometric dimension deviations compared with factory prefabricated products, and their mutual coordination is poor, resulting in uneven sizes of splicing gaps; the splicing surfaces of the door head panels, door frame uprights and door frame columns are bonded by caulking mortar, and the door frame columns are fixed to the walls or structural columns by anti-seismic clips, and at the same time, bonding is achieved on the splicing surfaces by caulking mortar. Due to the uneven sizes of splicing gaps and the different thicknesses of the caulking mortar in the splicing joints, the bonding strength at the door opening joints is low; in order to further prevent cracking and level the joints in the prior art, it is also necessary to make a layer of mesh cloth and anti-cracking mortar on the large-area integral wall surface after the splicing is completed to enhance the crack resistance of the splicing joints and level the joints. After users have used the door openings built in this way for a period of time, due to the frequent opening and closing of the door, it is found that many cracks appear in the joints between the door headboard and the door frame vertical board and the door frame column at the inner corner; cracks also appear at the joints between the door frame column and the wall or structural column. The use of secondary construction mesh cloth plus anti-cracking mortar for leveling has the disadvantages of long construction period, high construction cost and high labor intensity; moreover, this method cannot ensure that the joints at the inner corners of the door opening and the joints between the door frame column and the wall or structural column will not crack.

[0004] Option 2: Use on-site cast-in-place and on-site masonry door openings. Cast-in-place and on-site masonry are old-style wet operations that produce a lot of construction waste, high costs, and long construction periods.

[0005] At the same time, the operation methods of on-site cutting, processing and building door openings, on-site pouring of door openings and on-site stacking of door openings result in large amounts of dust and garbage pollution, and are not in line with the current prefabricated green building orientation.

[0024] The present invention adopts the above technical solution and has the following advantages and technical effects:

[0025] 1. The two door frame connecting parts of the prefabricated door head plate in the present invention form the inner corner of the door opening with the door head, which abandons the drawback of the existing door opening structure splicing the door opening at the inner corner position where cracking is most likely to occur. The one-piece prefabricated door head plate moves the splicing position of the door opening structure to both sides of the door opening, that is, the door frame connecting part of the prefabricated door head plate of the present invention and the L-shaped notch fitting surface of the prefabricated door frame vertical plate; thereby completely solving the problem of cracking at the splicing position of the door opening caused by splicing the door head plate at the inner corner position of the door opening where cracking is most likely to occur in the existing door opening structure. At the same time, the one-piece prefabricated door head plate also realizes the staggered bite between the door frame vertical plate prefabricated with the L-shaped notch, improving the connection firmness between the prefabricated door head plate and the prefabricated door frame vertical plate.

[0026] 2. Since prefabricated mortar storage grooves are provided at the L-shaped notch of the prefabricated door frame uprights, the upper end faces of the prefabricated door frame columns and both sides of the prefabricated door head panels; when the door opening is actually built, the corresponding prefabricated mortar storage grooves are assembled to form a mortar storage channel, and the mortar is densely filled in the mortar storage channel; the prefabricated door head panel and the prefabricated door frame uprights, the prefabricated door head panel and the prefabricated door frame columns are bonded and connected by the mortar filled in the mortar storage channel, and the secondary connection body formed after the mortar is cured is thick and has strong bonding force. At the same time, the secondary connection body formed is equivalent to an internal plug, which has strong resistance and can effectively prevent relative displacement and deformation between the prefabricated door head panel and the prefabricated door frame uprights, and the prefabricated door head panel and the prefabricated door frame columns due to external forces.

[0027] 3. When actually building the door opening, a mortar storage channel is formed between the prefabricated door head plate and the prefabricated mortar storage groove on the side of the prefabricated door frame column and the joint surface of the assembled wall or structural column, and the mortar is densely filled in the mortar storage channel; the prefabricated door head plate and the prefabricated door frame column are bonded to the wall or structural column through the mortar filled in the mortar storage channel, and the secondary connection body formed after the mortar solidifies is thick and has strong bonding force. At the same time, the expansion bolts that fix the prefabricated door frame column and the secondary connection body form an integrated structure with strong resistance, which effectively prevents the relative displacement between the prefabricated door head plate, the prefabricated door frame column and the wall or structural column caused by external force, improves the firmness of the connection with the wall or structural column, and solves the problem of cracking between the prefabricated door frame column and the prefabricated door head plate and the wall or structural column.

[0028] 4. When actually building the door opening, the corresponding joint grooves of the edges of the prefabricated door headboard, prefabricated door frame uprights and prefabricated door frame columns are spliced ​​together to form an anti-crack edge sealing groove, and mesh cloth and anti-crack mortar are laid in the anti-crack edge sealing groove to form an anti-crack connector. The above-mentioned anti-crack connector and secondary connector firmly connect the prefabricated door headboard, prefabricated door frame uprights and prefabricated door frame columns from the inside to the outside, completely solving the problem of cracking at the joints of the door opening due to the frequent opening and closing vibration of the door; in addition, the above-mentioned anti-crack edge sealing groove also has the function of leveling the joints. In the later stage, there is no need to make another layer of mesh cloth and anti-crack mortar on the large-area overall wall surface for leveling, which reduces construction costs and improves construction efficiency.

[0029] 5. Steel bars are embedded in the prefabricated door head panels, prefabricated door frame uprights, and prefabricated door frame uprights to further improve the flexural and compressive strength of the prefabricated door head panels, prefabricated door frame uprights, and prefabricated door frame uprights.

[0030] 6. Pre-embed the steel bars extending from the lower end face of the door frame connection part or pre-embed the steel bar insert sleeve in the door frame connection part. When actually building the door opening, the prefabricated door head plate of the present invention is assembled with the matching prefabricated door frame vertical plate and prefabricated door frame column. Specifically, the steel bars extending from the lower end face of the door frame connection part are inserted into the steel bar insert sleeve at the L-shaped notch of the pre-embedded door frame vertical plate and the steel bar insert sleeve on the upper end face of the prefabricated door frame column, or the steel bar insert sleeve pre-embedded in the door frame connection part is respectively inserted into the steel bar insert sleeve pre-embedded in the door frame. The steel bar insertion sleeve at the L-shaped notch of the vertical plate and the steel bar insertion sleeve on the upper end face of the prefabricated door frame column are connected by inserting the steel bar component, and the mortar storage channel at their joint is densely filled with mortar. After the mortar is cured, the secondary connection body forms an integrated structure with the inserted steel bars, prefabricated door head plate, prefabricated door frame vertical plate, and prefabricated door frame column, further improving the connection strength and integrity between the prefabricated door head plate and the prefabricated door frame vertical plate and prefabricated door frame column, thereby improving the earthquake resistance and impact resistance of the door opening.

[0031] 7. Several baffles are prefabricated in the fourth prefabricated slurry storage tank on the opposite side of the L-shaped notch of the prefabricated door frame vertical plate, and the height of the baffles is less than the depth of the prefabricated slurry storage tank. The design of the baffles increases the resistance to mortar backflow, and reduces the problem of empty sections at the upper end of the slurry storage channel caused by the mortar flowing back downward along the slurry storage channel due to its own weight in a short period of time; the design of adding segmented baffles can also reduce the large empty sections at the top of the slurry storage channel caused by the shrinkage and sinking of the mortar during the solidification process; after the mortar in the slurry storage tank is solidified, the baffles are equivalent to the internal reinforcement inserted into the secondary connector, which improves the connection firmness between the prefabricated door frame vertical plate and the adjacent internal partition wall strips. At the same time, the baffles also strengthen the slurry storage tank on the side of the prefabricated door frame vertical plate.

[0032] 8. A prefabricated slurry storage groove is provided on the upper end surface of the door head of the prefabricated door head panel; it is convenient for the prefabricated door head panel to be installed and connected with the inner partition wall strips spliced ​​above the prefabricated door head panel, and a slurry storage channel is formed between the prefabricated slurry storage groove on the upper end surface of the door head and the matching surface of the inner partition wall strips spliced ​​above the prefabricated door head panel, and the slurry storage channel is densely filled with mortar. The secondary connecting body formed after the mortar solidifies is also equivalent to an inner bolt, which has strong bonding force and resistance, ensuring that the assembled prefabricated door head panel and the inner partition wall strips spliced ​​above the prefabricated door head panel have good connection firmness; prefabricated slurry storage grooves are provided on the upper end surfaces of the prefabricated door frame uprights, which are convenient for the installation and connection of the prefabricated door frame uprights with the top beams or floor slabs or the inner partition wall strips spliced ​​above the prefabricated door frame uprights; in addition, this structure can realize multi-faceted continuous grouting, thereby improving construction efficiency.

[0033] 9. A prefabricated grouting port connected to the fourth prefabricated grouting tank is provided on the prefabricated door frame vertical plate; a prefabricated grouting port connected to the sixth prefabricated grouting tank is provided on the prefabricated door frame column. The prefabricated grouting port is provided to facilitate the grouting operation, eliminating the need to drill the grouting port with a drill during grouting, improving construction efficiency, and avoiding damage to the prefabricated door frame vertical plate caused by drilling port construction.

[0034] 10. The door head panels, door frame uprights and door frame columns of the door opening structure of the present invention are prefabricated in the factory and installed on site, which ensures the consistency of the products and avoids the defects of large geometric size deviations caused by on-site cutting of door head panels and door frame uprights, thus solving the problems of large assembly errors and poor anti-cracking effects caused by on-site cutting and assembly of door openings.

[0035] 11. During actual construction, the door opening structure of the present invention can be installed by either slurrying or grouting to improve work efficiency.

[0036] In summary, the door opening structure of the present invention completely solves the problem of cracks at the joints of the door openings due to frequent opening and closing vibrations of the door; and it is easy to assemble each other during actual construction, thereby improving construction efficiency and reducing labor intensity; factory prefabrication reduces dust and noise pollution in traditional on-site cutting construction, improves the working environment, and responds to the green building action plan.

[0072] Example 3: Please refer to Figures 11 to 14 In order to further realize that the prefabricated door head plate and the prefabricated door frame vertical plate, and the prefabricated door head plate and the prefabricated door frame column are connected to form a whole, so as to have stronger crack resistance, the embedded steel bars in the door frame connecting part 112 of the prefabricated door head plate 110 extend out of the lower end surface of the door frame connecting part; corresponding to the above-mentioned extended steel bars, the first steel bar insertion sleeve 215 is embedded in the L-shaped notch of the prefabricated door frame vertical plate 210; corresponding to the above-mentioned extended steel bars, the second steel bar insertion sleeve 314 is embedded in the prefabricated door frame column; the steel bars at the lower ends of the two door frame connecting parts 112 of the prefabricated door head plate 110 are correspondingly inserted in the steel bar insertion sleeves of the prefabricated door frame vertical plate 210 and the prefabricated door frame column 310. The mortar storage channels at their joints are densely filled with mortar. After the mortar is cured, the secondary connector forms an integrated structure with the inserted steel bars, prefabricated door head panels, prefabricated door frame uprights, and prefabricated door frame columns, further improving the connection strength and integrity between the prefabricated door head panels and prefabricated door frame uprights, and between the prefabricated door head panels and prefabricated door frame columns, effectively improving the vibration and impact resistance of the door opening.

[0073] Example 4: Please refer to Figure 15 to Figure 16 In order to further realize that the prefabricated door head plate and the prefabricated door frame vertical plate, and the prefabricated door head plate and the prefabricated door frame column are connected to form a whole, so as to have stronger crack resistance, the two door frame connecting parts 112 of the prefabricated door head plate are pre-embedded with a third steel bar insertion sleeve 116; the L-shaped notch of the prefabricated door frame vertical plate 210 corresponding to the position of the above-mentioned third steel bar insertion sleeve 116 is pre-embedded with a first steel bar insertion sleeve 215; the prefabricated door frame column is pre-embedded with a second steel bar insertion sleeve 314 corresponding to the position of the above-mentioned third steel bar insertion sleeve 116; the steel bar component 600 is respectively inserted into the third steel bar insertion sleeve 116 of the prefabricated door head plate 110 and the first steel bar insertion sleeve 215 of the prefabricated door frame vertical plate 210, the third steel bar insertion sleeve 116 of the prefabricated door head plate 110 and the second steel bar insertion sleeve 314 of the prefabricated door frame column 310 for connection. The mortar storage channels at their joints are densely filled with mortar. After the mortar is cured, the secondary connector forms an integrated structure with the inserted steel bars, prefabricated door head panels, prefabricated door frame uprights, and prefabricated door frame columns, further improving the connection strength and integrity between the prefabricated door head panels and prefabricated door frame uprights, and between the prefabricated door head panels and prefabricated door frame columns, effectively improving the vibration and impact resistance of the door opening.

[0074] Example 5: Please refer to Fig.17In order to reduce the empty section caused by the shrinkage and sinking of the mortar filled in the mortar storage channel formed by the splicing, a plurality of baffles 217 are prefabricated in the fourth prefabricated mortar storage groove opposite to the L-shaped notch 211 of the prefabricated door frame vertical plate 210 along the height direction, and the height of the baffles is less than the depth of the prefabricated mortar storage groove;

[0075] See also Fig.25 Several baffles 315 are integrally prefabricated in the sixth prefabricated slurry storage tank 312 on the side of the prefabricated door frame column along the height direction;

[0076] The height of the baffle is less than the depth of the prefabricated slurry storage tank.

[0077] The design of the partition has the following advantages:

[0078] 1. When the grouting process is actually adopted, the mortar is injected upward from the grouting port at the lower end by pressure. After the grouting is completed, the grouting head is pulled out and the grouting port is quickly blocked. In the moment before blocking, the mortar will flow back downward along the mortar storage channel. Once the mortar flows back too fast, a hollow section will appear at the upper end of the mortar storage channel. The multiple baffles of this design increase the resistance of the mortar backflow and slow down the backflow speed, thereby reducing the phenomenon of the mortar hollow section at the upper end of the mortar storage channel.

[0079] 2. Since the mortar shrinks and sinks to a certain extent during the solidification process, the design of segmented barriers can reduce the phenomenon of large empty sections on the top of the mortar storage channel caused by the shrinkage and sinking of the mortar;

[0080] 3. At the same time, it also strengthens the prefabricated mortar storage tank of the prefabricated door frame vertical plate; after the mortar in the mortar storage tank is solidified, it is equivalent to the internal reinforcement inserted into the secondary connecting body; after the mortar in the prefabricated mortar storage tank is solidified, it is equivalent to the internal reinforcement inserted into the secondary connecting body, which improves the firmness of the connection between the prefabricated door frame vertical plate and the adjacent internal partition wall strips.

[0081] Example 6: Please refer to Figures 18 to 21 The upper end surface of the door head 111 of the prefabricated door head plate is provided with a seventh prefabricated slurry storage groove 117 and / or the upper end surface of the prefabricated door frame vertical plate 210 is provided with an eighth prefabricated slurry storage groove 216. The prefabricated door head plate with this structure and the connected prefabricated door frame vertical plate and the inner partition wall strip plate 700 with the prefabricated slurry storage groove on the upper end are assembled to form a slurry storage channel, which can realize multi-faceted continuous grouting, densely fill the mortar in the slurry storage channel, and the secondary connection body formed after the mortar solidifies also forms an inner plug, which has strong bonding force and resistance, ensuring that the assembled door opening and the adjacent inner partition wall strip plates have good connection firmness.

[0082] By adopting this structure, inner partition wall strips with prefabricated slurry storage grooves can be cut on the upper part of the prefabricated door head plate or the prefabricated door frame vertical plate according to the actual required height and used as splicing plates for splicing. Since the sixth prefabricated slurry storage groove is provided on the upper end surface of the prefabricated door head plate or the seventh prefabricated slurry storage groove is provided on the upper end surface of the prefabricated door frame vertical plate, it is convenient to install and connect the prefabricated door head plate, the prefabricated door frame vertical plate and the inner partition wall strips with prefabricated slurry storage grooves spliced ​​above the prefabricated door head plate and the prefabricated door frame vertical plate, and a slurry storage channel is formed between the matching surfaces of the prefabricated door head plate, the prefabricated door frame vertical plate and the inner partition wall strips, and the mortar is densely filled in the slurry storage channel. After the mortar solidifies, a secondary connector with an internal bolt function is formed, ensuring that the assembled prefabricated door frame vertical plate and the inner partition wall strips spliced ​​above the prefabricated door frame vertical plate have good connection firmness.

[0083] The width of the slot openings of the first to seventh prefabricated slurry storage tanks 120 is greater than the width of the bottom of the prefabricated slurry storage tanks, which is beneficial for demoulding during actual production and improves production efficiency.

[0084] Example 7: Please refer to Fig. 22 A first prefabricated grouting port 218 connected to the fourth prefabricated grouting tank is provided on the prefabricated door frame vertical plate 210. A second prefabricated grouting port 316 connected to the sixth prefabricated grouting tank 312 is provided on the prefabricated door frame column 310. The use of the prefabricated grouting port facilitates the grouting operation, eliminating the need to drill the grouting port with a drill during grouting, improving construction efficiency, and avoiding damage to the prefabricated door frame vertical plate caused by drilling.

[0085] Example 8: Please refer to Fig.23 The prefabricated door frame vertical plate body on the L-shaped notch side is a solid structure; the prefabricated door frame vertical plate body on the other side of the L-shaped notch is prefabricated with a center hole 219 in the height direction. The design of the center hole further reduces the weight of the door frame vertical plate, and pipelines can be installed in the center hole, which is conducive to the layout of pipelines near the door opening.
