Description

Technical Field

[0001] The utility model belongs to the field of fixed buildings, in particular to a door opening blocking structure. Background Art

[0002] During the current construction of buildings, door openings are often provided on the exterior walls of buildings to connect with adjacent buildings or adjacent underground passages through the door openings on the exterior walls of buildings. However, it is impossible to determine when the building will be used and when the adjacent buildings or adjacent underground passages will be constructed. Therefore, there is a need to seal the door openings in the basements of buildings.

[0003] Currently, the following two solutions are used to seal door openings: the first is to use reinforced concrete walls to seal them. Since the first method uses reinforced concrete walls, it is necessary to wait for the reinforced concrete walls to solidify, the construction period is long, and the materials removed later cannot be reused, the cost is high, and it is not environmentally friendly. The second is to use brick walls to seal them. Since the second method uses brick walls, which have weak bending and shear resistance, if the door opening is deep below the ground, the environment opposite the brick wall often has a large soil pressure, and the second method cannot meet the bending and shear resistance requirements.

Therefore, the two sides of the first wall 2011 are divided into the indoor part of the building and the outdoor part of the building by the prefabricated component 101, and the first side corresponds to the side outside the building. Then, the first limiting component 102 is arranged on the first side of the first wall 2011, which is equivalent to the first limiting component 102 being arranged on the wall surface corresponding to the outdoor of the first wall 2011.

[0027] The truss 103 is arranged on the second side of the first wall 2011; the second side is a side of the first wall 2011 corresponding to the interior of the building, and each bottom chord 1031 of the truss 103 is provided with a through hole 105, and the through hole 105 is threadedly connected to the fastening assembly 104, and the through hole 105 is arranged corresponding to the first side of the prefabricated part 101.

[0028] In the embodiment of the utility model, the second side corresponds to a side inside the building, and the truss 103 of the utility model is arranged on the second side of the first wall 2011, which is equivalent to arranging the truss 103 on the wall surface inside the first wall 2011 corresponding to the room.

[0029] In the embodiment of the utility model, the truss 103 includes: a plurality of bottom chords 1031, a plurality of struts 1032, and a plurality of tie rods 1033. Figure 1 , Figure 3 As shown, multiple bottom chords 1031 are arranged in parallel, multiple struts 1032 are arranged in parallel, and one bottom chord 1031 corresponds to multiple struts 1032. For the struts 1032 corresponding to the same bottom chord 1031, a group of tension rods 1033 are provided. The struts 1032 are perpendicular to the bottom chord 1031 and one end of the struts 1032 is connected to the corresponding bottom chord 1031. The tension rods 1033 are used to connect the other ends of different struts 1032 and to connect the other end of the struts 1032 to the bottom chord 1031.

[0030] In the embodiment of the utility model, a through hole 105 is provided on the bottom chord 1031 , and the through hole 105 is threadedly connected to the fastening assembly 104 , so that the fastening assembly 104 can be screwed onto the bottom chord 1031 .

[0031] In the embodiment of the present invention, the first surface of the prefabricated component 101 is a surface of the prefabricated component 101 corresponding to the interior of the building.

[0032] The fastening assembly 104 is used to pass through the through hole 105 and connect with the first surface of the preform 101 when tightened, so as to apply force to the preform 101 toward the outside of the room, so that the preform 101 is connected with the first limiting assembly 102.

[0033] In the embodiment of the utility model, a truss 103 is arranged indoors in a building, and a through hole 105 is provided on the bottom chord 1031 of the truss 103, and the through hole 105 is arranged corresponding to the first surface of the prefabricated part 101, so that when the bottom chord 1031 of the truss 103 is threadedly connected with the fastening component 104 through the through hole 105, the fastening component 104 will face the first surface of the prefabricated part 101, and then when the fastening component 104 is tightened, the fastening component 104 passes through the through hole 105 and contacts the first surface of the prefabricated part 101 to apply a force to the prefabricated part 101 toward the outdoors.

[0034] In the embodiment of the utility model, the prefabricated member 101 is arranged in the door opening 202 to block the door opening 202, and the prefabricated member 101 is fixed by the first limiting assembly 102 and the truss 103. Specifically, the bottom chord 1031 of the truss 103 has a through hole 105, and the through hole 105 has a corresponding thread, and then the fastening assembly 104 is connected to the bottom chord 1031 of the truss 103 through the through hole 105. Since the through hole 105 is arranged correspondingly to the first surface of the prefabricated member 101, Therefore, when the fastening component 104 is tightened, the fastening component 104 passes through the through hole 105 and is connected to the first surface of the prefabricated component 101, thereby applying a force to the prefabricated component 101 toward the outside of the room, so that the prefabricated component 101 is connected to the first limiting component 102 outdoors, and the first limiting component 102 applies a force to the prefabricated component 101 toward the room, which is equivalent to applying a force to the prefabricated component 101 toward the room and a force toward the outside of the room at the same time, thereby achieving the fixation of the prefabricated component 101.

[0035] In the embodiment of the utility model, the prefabricated part 101 is used to block the door opening 202, and the prefabricated part 101 is fixed by the first limit assembly 102, the truss 103, and the fastening assembly 104. Since the prefabricated part 101, the first limit assembly 102, the truss 103, and the fastening assembly 104 can all be prefabricated, only assembly construction is required on site, so the construction period is short, and the dismantled prefabricated part 101, the first limit assembly 102, the truss 103, and the fastening assembly 104 can be reused, which is more environmentally friendly and has a lower cost. In addition, since the truss 103 is used, the structural strength is better, which can meet the environment with large soil pressure and has richer application scenarios.

[0036] In the present invention, in order to facilitate assembly and improve the fixing effect of the prefabricated component 101, the door opening blocking structure 10 also includes: a first connecting component 106; the first connecting component 106 is pre-embedded in the first wall 2011, and the first connecting component 106 is connected to the first limiting component 102.

[0037] In the present invention, when manufacturing the exterior wall 201, the first connection component 106 can be pre-embedded in the first wall 2011 corresponding to the door opening 202 in the exterior wall 201. After the first connection component 106 is pre-embedded, other construction processes can be performed, such as manufacturing the interior wall of the building. When the door opening 202 needs to be blocked later, the first connection component 106 is connected to the first stop component 102. Therefore, the present invention pre-embeds the first connection component 106 in the first wall 2011, so that the first stop component 102 does not need to be immediately set on the first side of the first wall 2011 after the first wall 2011 is manufactured. When the door opening 202 needs to be blocked later, the first connection component 106 can be connected to the first stop component 102, which facilitates assembly.

[0038] At the same time, by pre-embedding the first connecting component 106 in the first wall 2011 and connecting the first connecting component 106 to the first limiting component 102, the first limiting component 102 can be effectively supported and fixed by the first wall 2011, and then when the first limiting component 102 is connected to the prefabricated component 101, the prefabricated component 101 can be effectively fixed.

[0039] Optionally, when pre-embedding the first connection component 106, the first connection component 106 may be completely pre-embedded in the first wall 2011 corresponding to the door opening 202. When the first connection component 106 and the first stopper component 102 need to be connected, a groove may be made in the first wall 2011 corresponding to the door opening 202 to expose the first connection component 106, and then the first connection component 106 and the first stopper component 102 are welded. Optionally, when pre-embedding the first connection component 106, only a portion of the first connection component 106 may be pre-embedded in the first wall 2011 corresponding to the door opening 202, and the other portion of the first connection component 106 may be exposed, so as to facilitate welding of the first connection component 106 and the first stopper component 102.

[0040] Optionally, the first position limiting assembly 102 may be connected to the first wall 2011 in other ways, for example, the first position limiting assembly 102 may be fixed to the first wall 2011 by expansion bolts. The present invention does not impose any limitation on this.

[0041] In the utility model, the first connecting component 106 includes: a first connecting member 1061), a second connecting member 1062), and the first limiting component 102 includes a first angle steel 1021), a second angle steel 1022); the first connecting member 1061 is embedded in the upper end of the first wall 2011; the first connecting member 1061 is connected to the first angle steel 1021; the first angle steel 1021 is connected to the upper end of the prefabricated member 101; the second connecting member 1062 is embedded in the lower end of the first wall 2011; the second connecting member 1062 is connected to the second angle steel 1022; the second angle steel 1022 is connected to the lower end of the prefabricated member 101.

[0042] Among them, since the height A4 of the door opening 202 of the basement is often lower than the height of the ceiling of the basement, the upper end of the first wall 2011 is the portion of the first wall that is lower than the ceiling and higher than the upper end of the door opening. Since the prefabricated member 101 is arranged at the door opening 202 at the outer wall 201 of the building basement, in order to prevent rainwater from flowing into the building basement, it is necessary to arrange a portion protruding upward relative to the ground at the ground corresponding to the door opening 202, and the lower end of the first wall 2011 is the portion of the first wall 2011 that is higher than the ground corresponding to the door opening and lower than the door opening.

[0043] The upper end of the prefabricated component 101 is an end of the prefabricated component 101 close to the upper end of the first wall 2011 , and the lower end of the prefabricated component 101 is an end of the prefabricated component 101 close to the lower end of the first wall 2011 .

[0044] Optionally, the first connecting piece 1061 is welded to the first angle steel 1021 , and the second connecting piece 1062 is welded to the second angle steel 1022 ; the first angle steel 1021 abuts against the upper end of the prefabricated part 101 ; and the second angle steel 1022 abuts against the lower end of the prefabricated part 101 .

[0045] Furthermore, in order to facilitate assembly and improve the fixing effect of the prefabricated component 101, the door opening blocking structure 10 also includes: a second connecting component 107; the second connecting component 107 is connected to the bottom chord 1031 of the truss 103; the second connecting component 107 is pre-buried in the first wall 2011, or the second connecting component 107 is pre-buried in the first wall 2011 and the ground corresponding to the door opening 202.

[0046] In the present invention, when manufacturing the first wall 2011, the second connection component 107 can be embedded in the first wall 2011. After embedding the second connection component 107, other construction processes can be carried out until the entire building body is completed. When the door opening needs to be blocked later, the second connection component 107 is connected to the bottom chord 1031 of the truss 103. Therefore, the present invention embeds the second connection component 107 in the first wall 2011, so that the truss 103 does not need to be immediately arranged on the second side of the first wall 2011 after manufacturing the first wall 2011. When the second connection component 107 is connected to the bottom chord 1031 of the truss 103, the first wall 2011 can be used to firmly fix the truss 103, so that the fastening component 104 on the truss 103 can give the prefabricated part 101 a force to act outdoors, and when the first limit component 102 is connected to the prefabricated part 101, the prefabricated part 101 is effectively fixed.

[0047] Specifically, the second connecting component 107 includes: a third connecting member 1071 and a fourth connecting member 1072; the third connecting member 1071 is connected to the first end of the bottom chord 1031 of the truss 103, and the third connecting member 1071 is pre-buried in the upper end of the first wall 2011; the fourth connecting member 1072 is connected to the second end of the bottom chord 1031 of the truss 103; the fourth connecting member 1072 is pre-buried in the lower end of the first wall 2011 or the ground.

[0048] The third connecting member 1071 includes: a first connecting portion 10711 and a second connecting portion 10712; the first connecting portion 10711 is embedded in the upper end of the first wall 2011, one end of the second connecting portion 10712 is welded to the first connecting portion 10711, and the other end of the second connecting portion 10712 is connected to the first end of the bottom chord 1031 of the truss 103 by bolts; the fourth connecting member 1072 includes: a third connecting portion 10721 and a fourth connecting portion 10722; When the height A1 of the lower end of the first wall 2011 is greater than or equal to 300 mm, the third connection part 10721 is pre-buried in the lower end of the first wall 2011; when the height A1 of the lower end of the first wall 2011 is less than 300 mm, the third connection part 10721 is pre-buried in the ground; one end of the fourth connection part 10722 is welded to the third connection part 10721, and the other end of the fourth connection part 10722 is connected to the second end of the bottom chord 1031 of the truss 103 by bolts.

[0049] Among them, when the height A1 of the lower end of the first wall 2011 is less than 300 mm, if the third connecting part 10721 is embedded in the lower end of the first wall 2011, due to the low height of the lower end of the first wall 2011, there is insufficient space and strength at the lower end of the first wall 2011, and the third connecting part 10721 cannot be fully accommodated or the strength is insufficient after accommodating the third connecting part 10721. Therefore, when the height A1 of the lower end of the first wall 2011 is greater than or equal to 300 mm, the third connecting part 10721 is embedded in the lower end of the door opening 202 of the first wall 2011; when the height A1 of the lower end of the door opening 202 of the first wall 2011 is less than 300 mm, the third connecting part 10721 is embedded in the ground corresponding to the door opening 202.

[0050] Figure 3 It is a cross-sectional view of a door opening blocking structure 10 provided in an embodiment of the utility model.

[0052] In the present invention, the prefabricated member 101 includes at least one prefabricated panel 1011, which are arranged side by side, and the width direction of each prefabricated panel 1011 is parallel to the width direction of the door opening, so when the prefabricated member 101 is arranged in the door opening 202, the prefabricated member 101 will block the door opening 202. The specific size of the door opening 202, the specific size and quantity of the prefabricated member 101 can be set according to actual needs, and the present invention does not limit this.

[0053] The fastening assembly 104 in the present invention includes a plurality of bolt assemblies 1041 ; the plurality of bolt assemblies 1041 are distributed in an array.

[0054] In the utility model, at least one row of bolt assemblies 1041 is respectively provided for each prefabricated panel 1011, so that when the bolt assemblies 1041 are tightened on the bottom chord 1031 of the truss 103, the upper end of each prefabricated panel 1011 and the lower end of the prefabricated panel 1011 can be subjected to the force acting outdoors, so that each prefabricated panel 1011 is subjected to the force acting outdoors more evenly.

[0055] In the present invention, it is considered that if the fastening assembly 104 is directly connected to the first surface of the prefabricated member 101, the prefabricated member 101 may be damaged. Therefore, the fastening assembly 104 further includes at least one structural member 108. Specifically, the structural member 108 is arranged on the first surface of the prefabricated member 101; each structural member 108 corresponds to a row of the bolt assemblies 1041; the structural member 108 is used to connect with the corresponding bolt assembly 1041 when the bolt assembly 1041 is tightened, so as to transmit the force of the prefabricated member 101 toward the outside.

[0056] When the structural member 108 is disposed on the first surface of the prefabricated member 101, the structural member 108 can be attached to the prefabricated member 101 by gluing, or the structural member 108 can be connected to the prefabricated member 101 by expansion bolts. When the prefabricated member 101 includes a plurality of prefabricated panels 1011, one structural member 108 corresponds to a plurality of prefabricated panels 1011.

[0057] The utility model arranges a structural member 108 on the first surface of the prefabricated member 101, so that when the door opening blocking structure is installed at the door opening, the fastening assembly 104 is tightened in the through hole 105 so that the structural member 108 is located between the fastening assembly 104 and the prefabricated member 101. Since the contact area between the structural member 108 and the first surface is larger than the contact area between the bolt assembly 1041 in a row and the structural member 108, the force per unit area of ​​the first surface of the prefabricated member 101 is reduced, that is, the fastening assembly 104 is prevented from damaging the prefabricated member 101, and the structural member 108 protects the prefabricated member 101.
