Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a concrete pouring formwork system for interlayer joints. Background Technology

[0002] During the construction of the main structure of a building project, inadequate concrete treatment at the joints between floors can easily lead to appearance defects, such as grout leakage, honeycomb pitting, rotten roots, misalignment, and water seepage, causing potential quality problems and owner complaints.

[0003] Currently, the reinforcement method for concrete pouring formwork at the joint of floors is to move the formwork of the upper structure downwards and reinforce it by reserving tie rods or embedding three-section tie rods. This method requires reinforcement of the moved formwork on the already poured concrete wall, but the reinforcement effect is difficult to control, the operation is relatively troublesome, and it is easy to cause quality problems at the joint due to improper operation. Utility Model Content

[0004] The purpose of this invention is to provide a concrete pouring formwork system for interlayer joints to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is: a concrete pouring formwork system for interlayer joints, which includes: a first formwork, a second formwork, a Z-shaped component and pre-embedded fasteners. The first formwork and the second formwork are arranged correspondingly, and the bottom end of the first formwork is lower than the bottom end of the second formwork. The Z-shaped component is located below the first formwork, and its bottom end is fixed by the pre-embedded fasteners, while its top side abuts against the side of the first formwork.

[0006] Furthermore, the Z-shaped component includes a first section, a second section, and a third section connected in sequence. The first section abuts against the side of the first template, the second section supports the first template, and the third section connects to the pre-embedded fastener.

[0007] Furthermore, the first segment is perpendicular to the second segment, and the third segment is perpendicular to the second segment.

[0008] Furthermore, the pre-embedded fastener includes a pre-embedded threaded sleeve, a high-strength bolt, and a buffer washer. The pre-embedded threaded sleeve is horizontally arranged, and the high-strength bolt passes through the buffer washer and the third section in sequence, connecting to the pre-embedded threaded sleeve.

[0009] Furthermore, the first template is provided with a sealing gasket, which is located between the first template and the second template, with its top end flush with or lower than the bottom end of the second template.

[0010] Furthermore, a wedge pin is provided between the top side of the Z-shaped piece and the first template, and the two sides of the wedge pin respectively abut against the Z-shaped piece and the first template.

[0011] Furthermore, the wedge pin includes a first wedge pin and a second wedge pin. A vertical reinforcing rib is provided between the first wedge pin and the first template, and a horizontal reinforcing rib is provided between the second wedge pin and the first template. The vertical reinforcing rib and the horizontal reinforcing rib are respectively fixedly connected to the first template.

[0012] Furthermore, several groups of Z-shaped members are evenly distributed along the extension direction of the transverse reinforcing back ribs, and the several groups of Z-shaped members are respectively connected to different vertical reinforcing back ribs. The number of vertical reinforcing back ribs is greater than or equal to the number of Z-shaped members.

[0013] Furthermore, the first template and the second template are connected by several sets of tie bolts, which are located above the Z-shaped member.

[0014] The beneficial effects of this utility model are as follows: By supporting the bottom end and pressing the sides of the first template with the Z-shaped component, the portion of the bottom end of the first template that extends beyond the second template can be pressed against the side of the lower wall, reducing gaps and preventing concrete slurry from overflowing from the gap between the first template and the side of the lower wall when pouring the upper layer of concrete. This avoids aesthetic and structural stability problems such as rough surfaces and slurry leakage, and also avoids delays in construction progress, increased material consumption, and higher labor costs caused by secondary treatment or repairs. Furthermore, the template system is easy to install and dismantle, which can effectively improve construction efficiency. Attached Figure Description

In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0030] Reference Appendix Figure 1-2 This utility model provides a concrete pouring formwork system for interlayer joints, comprising: a first formwork 1, a second formwork 2, tie bolts 3, Z-shaped members 4, and pre-embedded fasteners 5. The first formwork 1 and the second formwork 2 are correspondingly arranged and connected and fastened by multiple sets of tie bolts 3. The bottom end of the first formwork 1 is lower than the bottom end of the second formwork 2, and the bottom end of the second formwork 2 abuts against the top surface of the lower floor slab. The side of the first formwork 1 facing the second formwork 2 abuts against the side of the lower wall. A portion of the Z-shaped member 4 is located below the first formwork 1, and its bottom end is fixed to the side of the lower wall by the pre-embedded fasteners 5. Its top side abuts against the side of the first formwork 1.

[0031] By adopting the above technical solution, the bottom end of the first template 1 is supported and the sides are pressed by the Z-shaped component 4. The part of the bottom end of the first template 1 that extends beyond the second template 2 can be pressed against the side of the lower wall, reducing the gap and preventing concrete slurry from overflowing from the gap between the first template 1 and the side of the lower wall when pouring the upper layer of concrete. This avoids problems such as rough surface and leakage, which affect the aesthetics and structural stability. It also avoids problems such as construction delays, increased material consumption, and increased labor costs caused by secondary treatment or repair.

[0032] Reference Appendix Figure 2The Z-shaped component 4 includes a first section 41, a second section 42 and a third section 43 connected in sequence. The first section 41 abuts against the side of the first template 1, the second section 42 is located at the bottom of the first template 1 and is used to support the first template 1, and the third section 43 is connected to the pre-embedded fastener 5.

[0033] To improve the fixing effect and enhance the fit between the Z-shaped component 4 and the first template 1 and the side of the lower wall, in this embodiment, the Z-shaped component 4 is configured such that the first segment 41 is perpendicular to the second segment 42, and the third segment 43 is perpendicular to the second segment 42. Thus, the first segment 41 is parallel to the side of the first template 1, the second segment 42 is parallel to the bottom surface of the first template 1, and the third segment 43 is parallel to the side of the lower wall, which can further improve the fastening effect on the first template 1 and improve the quality of the project.

[0034] Reference Appendix Figure 2 The pre-embedded fastener 5 includes a pre-embedded threaded sleeve 51, a high-strength bolt 52, and a buffer washer 53. The pre-embedded threaded sleeve 51 is horizontally set and pre-embedded in the lower wall, with its opening facing the outer side of the lower wall to facilitate the installation of the high-strength bolt 52. During construction, the third section 43 of the Z-shaped part 4 is pressed against the outer side of the lower wall, and a hole is drilled in the third section 43 to facilitate the installation of the high-strength bolt 52. Then, the high-strength bolt 52 passes through the buffer washer 53 and the third section 43 in sequence and is connected to the pre-embedded threaded sleeve 51.

[0035] The aforementioned pre-embedded fasteners 5 are easy to install and remove. The radial dimension of the pre-embedded threaded sleeve 51 is small, and high-strength steel material can be used, which will not affect the structural quality of the lower wall. After the Z-shaped piece 4 is removed, high-strength bolts 52 can be filled into the pre-embedded threaded sleeve 51, or concrete can be filled into the pre-embedded threaded sleeve 51 to make the side of the lower wall flat. In this way, the aesthetics of the lower wall will not be affected.

[0036] To further improve the sealing effect and prevent grout leakage and overflow, this embodiment also constructs a sealing gasket 10 on the first template 1. The sealing gasket 10 is located between the first template 1 and the second template 2, with its top end flush with or lower than the bottom end of the second template 2, in order to fill the gap between the side of the first template 1 and the side of the lower wall, and ensure the pouring quality.

[0037] To further improve system stability and ensure casting quality, this embodiment provides vertical reinforcing ribs 6 and horizontal reinforcing ribs 7 on the outer side of the first template 1. Several groups of vertical reinforcing ribs 6 are distributed along the extension direction of the horizontal reinforcing ribs 7. Wedge pins are constructed between the Z-shaped member 4 and the vertical reinforcing ribs 6, and between the Z-shaped member 4 and the horizontal reinforcing ribs 7. The first wedge pin 8 is located between the Z-shaped member 4 and the vertical reinforcing ribs 6, and its two sides abut against the Z-shaped member 4. Along with the vertical reinforcing back rib 6, the second wedge pin 9 is located between the Z-shaped piece 4 and the horizontal reinforcing back rib 7. The two sides of the second wedge pin 9 abut against the Z-shaped piece 4 and the horizontal reinforcing back rib 7 respectively. The first wedge pin 8 and the second wedge pin 9 are independent of each other to accommodate different thicknesses of the vertical reinforcing back rib 6 and the horizontal reinforcing back rib 7. This is because when the thicknesses of the vertical reinforcing back rib 6 and the horizontal reinforcing back rib 7 are inconsistent, the gap width between them and the Z-shaped piece 4 is also inconsistent, requiring wedge pins of different sizes to fill, abut, and reinforce them.

[0038] In this embodiment, the number of Z-shaped pieces 4 can be adjusted according to different construction needs. During implementation, several groups of Z-shaped pieces 4 are evenly arranged along the extension direction of the transverse reinforcing back rib 7 to improve the reinforcement effect. Among them, several groups of Z-shaped pieces 4 are connected to different vertical reinforcing back ribs 6 respectively, and the number of vertical reinforcing back ribs 6 should not be less than the number of Z-shaped pieces 4.

[0039] When using the above-mentioned formwork system for construction, the steps include:

[0040] (1) Before the lower wall is poured, a pre-embedded screw sleeve 51 is pre-embedded at a designated position below the joint. After the concrete of the lower structure is poured and meets the strength requirements, the pouring template of the lower structure is removed and the pre-embedded screw sleeve 51 is inspected and cleaned.

[0041] (2) Install Z-shaped part 4, attach the third section 43 to the outer side of the lower wall, and fix it with high-strength bolts 52 and pre-embedded threaded sleeves 51.

[0042] (3) A sealant 10 is pasted on the top side of the lower wall.

[0043] (4) After the upper structure reinforcement project is completed, the first template 1 and the second template 2 are installed. The first template 1 is lowered onto the second section 42 of the Z-shaped piece 4 so that the second section 42 provides support for the first template 1.

[0044] (5) Install the vertical reinforcing back rib 6 and the horizontal reinforcing back rib 7 on the first template 1 in sequence, and use the first wedge and the second wedge to fill the gaps between the vertical reinforcing back rib 6 and the first section 41, and the horizontal reinforcing back rib 7 and the first section 41 respectively, and fix them.

[0045] (6) Install tie rods to connect and fix the first template 1 and the second template 2.

[0046] (7) After the formwork is accepted, pour the concrete for the upper structure. Once the concrete strength meets the requirements, remove the formwork system for reuse.

[0047] Compared with the prior art, the beneficial effects of this utility model are as follows: by supporting the bottom end of the first template 1 and pressing it against the side by the Z-shaped component 4, the part of the bottom end of the first template 1 that extends beyond the second template 2 can be pressed against the side of the lower wall, reducing gaps and preventing concrete slurry from overflowing from the gap between the first template 1 and the side of the lower wall when pouring the upper layer of concrete. This avoids problems such as rough surfaces and grout leakage that affect aesthetics and structural stability, and avoids problems such as construction delays, increased material consumption, and increased labor costs caused by secondary treatment or repair. Furthermore, the template system is easy to install and dismantle, which can effectively improve construction efficiency.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
