Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a formwork support device for preventing bulging and grout leakage in interior walls. Background Technology

[0002] In the construction of interior walls, formwork is usually used to reinforce the concrete to ensure that it maintains the correct shape and size during the pouring process. However, during the concrete pouring process, the bottom of the formwork is prone to bulging and grout leakage, which affects the construction quality of the interior walls.

[0003] The traditional solution is to pre-fill the bottom of the formwork with mortar to prevent leakage of concrete slurry. However, the filling of mortar is not always uniform, which can easily lead to an uneven surface after the concrete is poured. Moreover, cleaning the mortar after the formwork is removed is also quite troublesome. Summary of the Invention

[0004] This invention aims to solve the problem that the existing method of pre-filling mortar is cumbersome and easily affects the surface quality of concrete pouring. It provides a formwork support device for preventing bulging and grout leakage in interior wall formwork. This device creates a rigid constraint at the bottom of the formwork, thereby preventing bulging and grout leakage at the bottom of the interior wall formwork during concrete pouring.

[0005] The technical solution of this utility model is: a formwork support device for preventing bulging and grout leakage in interior walls, comprising an interior wall template and timber. A pouring space is formed between the inner sides of the interior wall template, and the timber is located on the outer side of the interior wall template. A reinforcing member is provided at the bottom between the interior wall template and the timber. The reinforcing member includes a horizontal part and a vertical part. The outer side of the interior wall template is provided with a slot one to accommodate the vertical part, and the inner side of the timber is provided with a slot two to accommodate the horizontal part. A groove is provided on the side of the vertical part near the interior wall template, and an elastic sealing element is provided in the groove. The timber can simultaneously abut against the vertical part and the outer side of the interior wall template, and at this time, the elastic sealing element is squeezed and deformed.

[0006] By adopting the above solution, a reinforcing member is provided at the bottom between the inner wall formwork and the timber, and slots one and two are respectively opened on the inner wall formwork and the timber to accommodate the reinforcing member. This allows the vertical and horizontal parts of the reinforcing member to fit tightly with the inner wall formwork and the timber. The timber can also tighten the upper part of the inner wall formwork while tightening the reinforcing member, thereby tightening the inner wall formwork, especially the bottom of the inner wall formwork. This can prevent the bottom of the inner wall formwork from expanding and leaking grout due to pressure during concrete pouring. Furthermore, during installation, simply place the reinforcing member at the bottom of the inner wall formwork, then install and tighten the wooden block. The elastic seal will be squeezed and deformed, thereby further achieving a seal. Compared with the method of pre-filling mortar, it is easier to remove the formwork after pouring.

[0007] Based on the above solution, the present invention can be further improved as follows: Furthermore, when the timber simultaneously abuts against the outer side of the vertical part and the inner wall template, the timber at both ends of the groove also abuts against the end of the horizontal part.

[0008] Furthermore, both the horizontal and vertical sections are sheet-like steel structures.

[0009] Furthermore, when the timber abuts against the outside of the vertical part and the inner wall template, the side of the vertical part closest to the inner wall template abuts against the outside of the inner wall template. This not only enhances the stability of the bottom of the inner wall template, but also prevents the elastic seal from being over-compressed, which would reduce its service life.

[0010] Furthermore, the elastic seal is elongated and its length direction is consistent with the length direction of the vertical part, and multiple elastic seals are provided along the height direction of the vertical part.

[0011] Furthermore, one of the resilient seals is located at the bottom of the vertical portion.

[0012] Furthermore, tie rods are provided between the timbers, and a reinforcing structure is provided on the outside of the timbers to reinforce the formwork support device.

[0013] The beneficial effects of this utility model through the above technical solution are as follows: In this invention, a reinforcing member is provided at the bottom between the inner wall formwork and the timber, and slots one and two are respectively provided on the inner wall formwork and the timber to accommodate the reinforcing member. This allows the vertical and horizontal parts of the reinforcing member to fit tightly with the inner wall formwork and the timber. The timber can also press against the upper part of the inner wall formwork while tightening the reinforcing member, thereby tightening the inner wall formwork, especially the bottom of the inner wall formwork. This can prevent the bottom of the inner wall formwork from expanding and leaking grout due to pressure during concrete pouring. Furthermore, during installation, it is only necessary to place the reinforcing member at the bottom of the inner wall formwork, and then install and tighten the timber. The elastic seal will be squeezed and deformed, thereby further achieving a seal. Compared with the method of pre-filling mortar, the demolding operation can be made easier after pouring.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-4 As shown, a formwork support device for preventing bulging and grout leakage in interior walls includes an interior wall template 1 and timber 2. A pouring space is formed between the inner sides of the interior wall template 1, and the timber 2 is located on the outer side of the interior wall template 1. The inner side of the interior wall template 1 is the opposite side of the template, and the outer side is the opposite side of the template. The timber 2 supports the interior wall template 1. In this embodiment, a rectangular plate is used. A reinforcing member 3 is provided at the bottom between the interior wall template 1 and the timber 2. Specifically, the reinforcing member 3 has a structure similar to angle steel and includes a horizontal part 301 and a vertical part 302. Part 302 is located at one end of the horizontal part 301 near the inner wall template 1. The outer side of the inner wall template 1 is provided with a slot 101 to accommodate the vertical part 302, and the inner side of the timber 2 is provided with a slot 201 to accommodate the horizontal part 301. The vertical part 302 has a groove on the side near the inner wall template 1. An elastic sealing element 4 is provided in the groove. The width of the slot 101 is equal to the width of the vertical part 302. The elastic sealing element 4 can be made of rubber or foam sealing strip. The timber 2 can simultaneously abut against the outer side of the vertical part 302 and the outer side of the inner wall template 1, and at this time the elastic sealing element 4 is squeezed and deformed.

[0017] In this embodiment, a reinforcing member 3 is provided at the bottom between the inner wall formwork 1 and the timber 2, and slots 101 and 201 for accommodating the reinforcing member 3 are respectively provided on the inner wall formwork 1 and the timber 2. This allows the vertical part 302 and the horizontal part 301 of the reinforcing member 3 to fit tightly with the inner wall formwork and the timber. The timber 2 can also press against the upper part of the inner wall formwork 1 while pressing against the reinforcing member 3, thereby pressing against the bottom of the inner wall formwork 1, especially the bottom of the inner wall formwork 1. This can prevent the bottom of the inner wall formwork 1 from expanding and leaking grout due to pressure during concrete pouring. Furthermore, during installation, it is only necessary to place the reinforcing member 3 at the bottom of the inner wall formwork 1, and then install and press against the timber 2. The elastic sealing member 4 will be squeezed and deformed, thereby further achieving a seal. Compared with the method of pre-filling mortar, it is easier to perform demolding operation after pouring.

[0018] As one possible implementation, when the timber 2 simultaneously abuts against the outer side of the vertical part 302 and the inner wall template 1, the timber 2 at the end of the groove 201 also abuts against the end of the horizontal part 301, thereby tightening the reinforcing member 3 and preventing the reinforcing member 3 from shifting.

[0019] As one possible implementation, both the horizontal part 301 and the vertical part 302 are sheet-like steel structures, ensuring that the reinforcement 3 has a certain strength.

[0020] As one possible implementation, when the timber 2 abuts against the vertical part 302 and the outer side of the inner wall template 1, the side of the vertical part 302 closest to the inner wall template 1 abuts against the outer side of the inner wall template 1. This not only enhances the stability of the bottom of the inner wall template 1, but also prevents the elastic sealing element 4 from being over-compressed, thus reducing its service life.

[0021] In one possible implementation, the elastic sealing element 4 is elongated and its length direction is consistent with the length direction of the vertical part 302. Multiple elastic sealing elements 4 are provided along the height direction of the vertical part 302. In this embodiment, four elastic sealing elements 4 are provided, each having multiple grooves.

[0022] In one possible implementation, one of the resilient seals 4 is located at the bottom of the vertical portion 302.

[0023] As one possible implementation, tie rods 5 are provided between the timbers 2, and a reinforcing structure is provided on the outside of the timbers 2 to reinforce the formwork support device. The tie rods 5 and the reinforcing structure can both adopt the existing structure. At the same time, in order to prevent the reinforcing parts 3 from shifting when squeezed, ribs can be provided between the horizontal part 301 and the vertical part 302, and corresponding slots can be opened at the bottom of the timbers 2 for limiting and locking. However, since even if displacement occurs, the amount of displacement is small and will not affect the support of the inner wall formwork 1, ribs are not provided in this embodiment.

[0024] In this embodiment, when used: First, install the inner wall formwork 1. Then, place the reinforcement 3 on the bottom outer side of the inner wall formwork 1 and insert the vertical part 302 of the reinforcement 3 into the groove 101 on the outer side of the inner wall formwork 1. Then, install the timber 2. The part of the timber 2 near the inner wall formwork 1 presses on the horizontal part 301 of the reinforcement 3, and the timber 2 at the end of the groove 201 is pressed against the reinforcement 3. Then, install the tie rod 5 and the reinforcement structure to press the timber 2, so that the timber 2 presses against the inner wall formwork 1 and the reinforcement 3. At this time, the side of the reinforcement 3 near the inner wall formwork 1 is pressed against the bottom of the inner wall formwork 1. The elastic seal 4 is squeezed and deformed to form a seal, thereby preventing the bottom of the inner wall formwork 1 from expanding and leaking grout due to pressure during the concrete pouring process.
