Description

Technical Field

[0001] This invention belongs to the field of building technology, and in particular relates to a protective fixing device and construction method for post-pouring strips. Background Technology

[0002] With the rapid pace of urban development, basement spaces in urban construction are becoming increasingly larger, which is an inevitable trend towards new building types and full utilization of underground space. In urban construction, basements are concealed works. During use, if the post-pouring strip of the basement floor slab is not properly protected during the post-pouring process, leakage may occur, resulting in long repair times and high costs. Therefore, the protection of the post-pouring strip of the basement is particularly important and prominent.

[0003] The extended retention time of post-pouring strips and insufficient protection measures not only lead to corrosion of the reinforcing steel in the post-pouring strips, but also cause structural safety and quality hazards due to the accumulation of construction waste within the post-pouring strips during construction and deformation caused by trampling. Furthermore, the post-pouring process brings difficulties in cleaning and secondary maintenance. Temporary formwork is usually laid for passage during construction, and the temporary formwork is damaged due to repeated displacement during cross-operation, resulting in the exposure of the post-pouring strips and creating safety hazards. Summary of the Invention

[0004] In view of the above problems, the present invention provides a post-pouring strip protection and fixing device and construction method to solve the above or other problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a post-pouring strip protection and fixing device, comprising multiple supporting structures, which are arranged sequentially along a first direction, and adjacent supporting structures are connected by a fixing structure; wherein,

[0006] The support structure includes a support template and at least two support members located on the same side of the support template. Multiple support members are arranged sequentially along a second direction. The fixing structure and the support members are respectively located on opposite sides of the support template. The first direction is perpendicular to the second direction.

[0007] Furthermore, in the second direction, among the multiple support members, the two outermost support members are at a certain distance from the side of the support template, with the distance being greater than 300mm.

[0008] Furthermore, there are two support components.

[0009] Furthermore, the thickness of the supporting template is greater than 12mm.

[0010] Furthermore, in the second direction, the distance between the two outermost supports among the plurality of supports is adapted to the width of the post-cast strip, so that the two outermost supports are fully embedded in the post-cast strip.

[0011] Furthermore, there is a gap between the side of the support member facing away from the support template and the main reinforcement bar inside the post-pouring strip, and the gap is greater than 4mm.

[0012] Furthermore, the supporting components are made of square timber.

[0013] Furthermore, in the first direction, there is a gap between two adjacent support structures.

[0014] Furthermore, the fixed structure is a door hinge, which is set along the first direction.

[0015] A construction method for a post-pouring strip protection and fixing device includes the following steps:

[0016] After the cast-in-place structure is completed, clean the debris inside the post-cast strip;

[0017] Based on the width of the post-cast strip, multiple support structures are prepared;

[0018] Multiple support structures are sequentially embedded into the post-pouring strip along its length. The support formwork overlaps with the load-bearing layer of the cast-in-place concrete slab, and adjacent support structures are fixed by a fixing structure.

[0019] Due to the adoption of the above technical solution, the post-cast strip protection and fixing device has multiple support structures. Adjacent support structures are connected by a fixing structure, and multiple support structures are connected together to form the overall structure of the post-cast strip protection and fixing device. The support structure consists of support templates and support components. The support components can fix the support structure on the post-cast strip. The support templates cover and protect the post-cast strip. The support templates and support components are inexpensive, easy to construct, and recyclable. By replacing the commonly used post-cast strip protection with the post-cast strip protection and fixing device, the problems of falling construction waste, repeated displacement and damage, and deformation caused by trampling are effectively solved. The protection effect is good. In the process of retaining the post-cast strip, the use of the post-cast strip protection and fixing device can effectively solve the problems of steel corrosion, waste accumulation, and deformation caused by trampling. It is easy to construct, inexpensive, and saves maintenance costs during use. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Figure 1 A schematic diagram of the support structure according to an embodiment of the present invention is shown. This embodiment relates to a protective fixing device and construction method for post-pouring strips. The protective fixing device for post-pouring strips has multiple support structures. Adjacent support structures are fixedly connected by fixing structures. The support structures are fully embedded in the post-pouring strip to protect it. This effectively solves the problems of construction waste falling, repeated displacement and damage, and deformation caused by trampling. The protective effect is good.

[0026] In existing technologies, the use of temporary formwork for passage presents several problems: damage due to overlapping construction operations, repeated displacement, difficulty in cleaning due to construction waste accumulation in the post-pouring strip, and quality and safety hazards caused by workers stepping on and deforming the formwork. To address these issues, this embodiment provides a protective and fixing device for the post-pouring strip, which is fixedly installed on the post-pouring strip to protect it.

[0027] A post-pouring strip protection and fixing device, such as Figure 1 and 2 As shown, it includes multiple support structures, which are arranged sequentially along the first direction. Adjacent support structures are connected by a fixing structure 4. The support structures are used to fully embed in the post-pouring strip to protect it. The fixing structure 4 is used to connect adjacent support structures, thereby connecting multiple support structures together to form an overall structure of the post-pouring strip protection fixing device. The number of support structures is selected and set according to the length of the support structure itself and the length of the post-pouring strip. No specific requirements are made here.

[0028] The supporting structure includes a supporting template 1 and at least two supporting members 2 located on the same side of the supporting template 1. Multiple supporting members 2 are arranged sequentially along a second direction. These supporting members 2 can be arranged at equal or unequal intervals along the second direction, depending on actual needs; no specific requirements are specified here. The supporting members 2 facilitate the full embedding of the supporting structure within the post-pouring strip and ensure the supporting structure is fixed within the post-pouring strip, preventing loosening and movement. Simultaneously, the supporting members 2 strengthen the supporting template 1 and extend its service life.

[0029] Here, the first direction and the second direction are set perpendicularly. The first direction is the length direction of the post-pouring strip, and the second direction is the width direction of the post-pouring strip. The length direction of the support template 1 is set along the first direction, and the width direction of the support template 1 is set along the second direction. Each support member 2 is set along the first direction, and the length of the support member 2 is adapted to the length of the support template 1.

[0030] The fixing structure 4 and the support member 2 are respectively set on the opposite sides of the support template 1. Multiple support members 2 are set on the side of the support template 1 facing the post-pouring strip, and the fixing structure 4 is set on the side of the support template 1 away from the post-pouring strip, so as to avoid interference between the support member 2 and the fixing structure 4 during the installation process.

[0031] The aforementioned support template 1 is a plate structure. This support template 1 can be an idle template on the construction site, reducing the cost of the support structure. In some feasible embodiments, the support template 1 is a square plate structure, and the thickness of the support template 1 is greater than 12mm. The thickness of the support template 1 can be selected and set according to actual needs, and no specific requirements are specified here.

[0032] In the second direction, among the multiple support members 2, the two outermost support members 2 are at a certain distance from the corresponding side of the support template 1. That is, the multiple support members 2 are arranged sequentially along the second direction. Therefore, among the multiple support members 2, two support members 2 are located on the outermost side, and the remaining support members 2 are located between the two outermost support members 2. The arrangement of the two outermost support members 2 is such that after the support structure is fully embedded in the post-pouring strip, the two outermost support members 2 contact the post-pouring strip to position and fix the support structure, and prevent the support structure from loosening after being fully embedded in the post-pouring strip, and thus prevent movement. The support structure is fixedly installed on the post-pouring strip.

[0033] This distance is greater than 300mm, and can be selected and set according to actual needs; no specific requirements are specified here. This distance ensures that a portion of the supporting formwork 1 is located outside the outermost supporting member 2, allowing the supporting formwork 1 to overlap with the load-bearing layer of the cast-in-place concrete slab, thus protecting the post-cast strip.

[0034] In some feasible embodiments, the number of the aforementioned support members 2 is two. Both support members 2 are arranged along the length direction (first direction) and the width direction (second direction) of the support template 1. There is a certain gap 5 between the two support members 2. There is a certain distance between one support member 2 and the side of the support template 1 adjacent to it, and there is a certain distance between the other support member 2 and the other side of the support template 1 adjacent to it. The distances are preferably 300mm. The two support members 2 divide the support template 1 into three parts. The two parts located far apart from each other on the two support members 2 are used to overlap with the load-bearing layer of the cast-in-place concrete slab, realizing the installation of the support structure and also realizing the protection of the post-pouring strip by the support structure.

[0035] In the second direction, the distance between the two outermost supports 2 of the plurality of supports 2 is adapted to the width of the post-cast strip. Here, the distance between the two outermost supports 2 is the distance between the two opposite sides of the two supports 2 in the second direction, so that the two outermost supports 2 are fully embedded in the post-cast strip to fix the support structure, so that the support structure is fixedly installed on the post-cast strip and will not move due to external forces. The two outermost supports 2 position and fix the support structure on the post-cast strip to prevent the support structure from moving due to loosening.

[0036] The aforementioned support member 2 is fixedly connected to the support template 1, and the support member 2 and the support template 1 are fixedly connected by bolts 3. Along the length direction of the support member 2, multiple bolts 3 are sequentially arranged to fix the support member 2 and the support template 1 together.

[0037] The side of the support member 2 facing away from the support template 1 has a gap with the main reinforcement in the post-pouring strip to prevent the support member 2 from contacting the main reinforcement in the post-pouring strip and to prevent wear on the main reinforcement in the post-pouring strip. The gap is greater than 4mm. The gap can be selected and set according to actual needs. No specific requirements are made here.

[0038] In some feasible embodiments, the support member 2 described above is preferably a square timber, which is a 40mm*60mm square timber.

[0039] In the first direction, there is a gap 5 between two adjacent support structures, and the two support structures do not contact each other to accommodate the deformation of the support template 1. The gap 5 can be selected and set according to actual needs, for example, it can be 10mm.

[0040] The aforementioned fixed structure 4 is a door hinge. The door hinge is set along the first direction, that is, the two blades of the door hinge are set along the first direction, and the multiple screw holes on the two blades are also set along the first direction, increasing the connection strength between two adjacent support structures.

[0041] Adjacent support structures are fixedly connected by at least two door hinges, increasing the stability and robustness of the connection between them. Multiple door hinges are arranged sequentially along the second direction. The door hinges are fixedly connected to the support template 1 with screws. During the connection process, the support template 1 and the door hinges are tightly fitted together before being reinforced with screws.

[0042] In some feasible embodiments, two adjacent support structures are fixedly connected by two door hinges, one door hinge corresponding to the outermost support member 2 and the other door hinge corresponding to the outermost other support member 2.

[0043] A construction method for a post-pouring strip protection and fixing device includes the following steps:

[0044] After the cast-in-place structure is completed, clean the debris in the post-cast strip and rinse it to keep the post-cast strip clean.

[0045] Based on the width of the post-pouring strip, multiple support structures are prepared. Here, the width of the post-pouring strip is the design width of the post-pouring strip in the drawing. That is, based on the design width of the post-pouring strip in the drawing, multiple support structures are prepared. The width between two support members 2 is determined (in the case of multiple support members 2, it is the width between the two outermost support members 2). After determining the width of the post-pouring strip by combining the idle formwork and square timber on the construction site, the formwork and square timber are fixed with bolts 3 to form a support structure. The distance between the two support members 2 and the side of the corresponding support formwork 1 is 300mm, which serves as the load-bearing overlap part for overlapping with the load-bearing layer of the cast-in-place concrete slab.

[0046] Prepare the required number of support structures based on the length of the post-cast strip;

[0047] Multiple support structures are sequentially embedded into the post-pouring strip along its length. The gap 5 between two adjacent support structures can be selected and set according to actual needs. The support template 1 overlaps with the load-bearing layer of the cast-in-place concrete slab. After ensuring that each support structure is not loose, two adjacent support structures are fixed by fixing structure 4. Two door hinges are arranged horizontally for fixing. The same method is used for fixing at the corners, with two door hinges arranged horizontally for fixing. Multiple support structures are connected to form a post-pouring strip protection and fixing device.

[0048] Due to the adoption of the above technical solution, the post-cast strip protection and fixing device has multiple support structures. Adjacent support structures are connected by a fixing structure, and multiple support structures are connected together to form the overall structure of the post-cast strip protection and fixing device. The support structure consists of support templates and support components. The support components can fix the support structure on the post-cast strip. The support templates cover and protect the post-cast strip. The support templates and support components are inexpensive, easy to construct, and recyclable. By replacing the commonly used post-cast strip protection with the post-cast strip protection and fixing device, the problems of falling construction waste, repeated displacement and damage, and deformation caused by trampling are effectively solved. The protection effect is good. In the process of retaining the post-cast strip, the use of the post-cast strip protection and fixing device can effectively solve the problems of steel corrosion, waste accumulation, and deformation caused by trampling. It is easy to construct, inexpensive, and saves maintenance costs during use.

[0049] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
