Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically to a support system for cast-in-place concrete structures that do not require formwork removal. Background Technology

[0002] Traditional support frames are independent load-bearing systems. The support points need to be densely distributed and evenly stressed. They consist of vertical supports, horizontal supports, timber, formwork, and through-wall bolts. The formwork is supported by a dense distribution of timber. On the outside of the timber, it also needs to be constrained by a dense distribution of steel pipes or timber through-wall bolts to form a support system to withstand the horizontal compressive force generated by the pouring of concrete and prevent the cast-in-place concrete wall from expanding or bursting. Support rods are needed for positioning and reinforcement to prevent the external forces generated during the pouring of concrete from causing the wall to deform or shift.

[0003] However, the existing traditional support frame has a relatively complex structure, which requires assembly during use. The strength of the support after assembly cannot be guaranteed, and phenomena such as bulging and bursting of the formwork are prone to occur, affecting construction efficiency and quality.

[0004] Therefore, how to provide a formwork-free cast-in-place concrete structure support system for wall panels that can be pre-assembled to prevent bulging and bursting is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a formwork-free cast-in-place concrete structure support system, which aims to solve one of the problems in the above-mentioned background technology, enabling the pre-assembly of the cavity cast-in-place concrete structure support system and improving construction efficiency and quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A formwork-free cast-in-place concrete structure support system includes:

[0008] A formwork-free wall panel mold, wherein the formwork-free wall panel mold has a concrete pouring cavity;

[0009] The support frame is provided in multiple ways. The multiple support frames are symmetrically arranged at the top and bottom of both sides of the non-removable mold wall panel. The support frames arranged at corresponding positions on both sides of the non-removable mold wall panel are connected by bolts.

[0010] Support rods are provided on both sides of the non-removable mold wall panel mold. One end of the support rod is detachably connected to the support frame at the top of the non-removable mold wall panel mold, and the other end of the support rod is detachably connected to the support frame at the bottom of the non-removable mold wall panel mold.

[0011] Furthermore, the formwork-free wall panel includes a precast mold and a steel mesh frame, the precast mold having the concrete pouring cavity, and the steel mesh frame being disposed within the concrete pouring cavity.

[0012] Furthermore, the end of the steel mesh frame near the inner wall of the concrete pouring cavity is prefabricated inside the precast mold.

[0013] Furthermore, the support frame includes a support plate and angle steel. The angle steel is fixedly installed on one corner of the support plate, and the support plate is perpendicular to the angle steel. One side wall of the angle steel is flush with the formwork of the non-removable wall panel, and the other side wall of the angle steel is flush with the upper or lower edge of the formwork of the non-removable wall panel. The angle steels at corresponding positions on both sides of the non-removable wall panel are connected by bolts. Both ends of the support rod are detachably connected to the support plate.

[0014] Furthermore, bolt holes are provided on both side walls of the angle steel. The bolt holes on the side wall flush with the formwork-free wall panel are used to pass through bolts connecting the angle steels on both sides of the formwork-free wall panel. The bolt holes on the side wall flush with the upper or lower edge of the formwork-free wall panel are used to connect the formwork-free wall panel to the reference panel.

[0015] Furthermore, the support plate is provided with lifting holes.

[0016] Furthermore, the support rod is a telescopic structure.

[0017] Furthermore, when there are multiple non-removable wall panel molds spaced apart, a connecting plate is also included. The connecting plate is disposed between adjacent non-removable wall panel molds, and the connecting plate is detachably connected to the support frame on the adjacent non-removable wall panel mold through the support rod.

[0018] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a formwork-free cast-in-place concrete structure support system. The formwork-free wall panel mold has a concrete pouring cavity. By installing support frames on both sides of the formwork-free wall panel mold, and connecting the support frames on both sides with bolts, concrete is directly poured into the concrete pouring cavity to finally form a formwork-free wall panel. This avoids the problems of mold bulging and bursting that are common with traditional support frames in the prior art. At the same time, the formwork-free wall panel mold in this formwork-free cast-in-place concrete structure support system is prefabricated, and the support frames and support rods are also prefabricated components. Therefore, during the wall construction process, the formwork-free wall panel mold can be directly transported to the site for assembly and hoisting before pouring concrete, thereby improving the construction efficiency and quality of the wall.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figure 1 and 2 This utility model discloses a formwork-free cast-in-place concrete structure support system, comprising:

[0027] No-removable formwork wall panel mold 1, which has a concrete pouring cavity 4;

[0028] Support frame 2, multiple support frames 2 are provided, and multiple support frames 2 are symmetrically arranged on the top and bottom of both sides of the non-removable mold wall panel 1. The support frames 2 arranged at corresponding positions on both sides of the non-removable mold wall panel 1 are connected by bolts.

[0029] Support rods 3 are provided on both sides of the non-removable mold wall panel mold 1. One end of the support rod 3 is detachably connected to the support frame 2 at the top of the non-removable mold wall panel mold 1, and the other end of the support rod 3 is detachably connected to the support frame 2 at the bottom of the non-removable mold wall panel mold 1.

[0030] It should be noted that: the formwork-free wall panel 1 is a precast concrete component. Support frames 2 are installed on both sides of the formwork-free wall panel 1. Support rods 3 are installed between the support frames 2 on the same side. The support rods 3 enhance the overall strength of the formwork-free wall panel 1. Simultaneously, the support frames 2 on both sides of the formwork-free wall panel 1 are connected by bolts. The bolts apply tensile force to the side walls of the formwork-free wall panel 1, thereby increasing its strength and preventing bulging and bursting during the cast-in-place concrete process. Furthermore, the support frames 2 can be used as hoisting points, facilitating the hoisting of the formwork-free wall panel 1 to the designated installation position. This design improves the construction efficiency of the wall and also solves the complex process of constructing the support frame 2 using multiple components such as timber, formwork, horizontal supports, and vertical supports in existing technologies.

[0031] According to some embodiments of this utility model, the formwork-free wall panel mold 1 includes a precast mold 11 and a steel mesh frame 12. The precast mold 11 has a concrete pouring cavity 4, and the steel mesh frame 12 is disposed inside the concrete pouring cavity 4. By setting the steel mesh frame 12 inside the concrete pouring cavity 4, the quality of the final constructed wall can be improved, and the strength of the wall can be guaranteed.

[0032] In the above embodiment, preferably, the end of the steel mesh 12 near the inner wall of the concrete pouring cavity 4 is prefabricated inside the precast mold 11. By prefabricating part of the steel mesh 12 inside the precast mold 11, the connection strength between the steel mesh 12 and the precast mold 11 can be improved, thereby preventing the precast mold 11 from bulging and bursting when pouring concrete into the concrete pouring cavity 4.

[0033] In this embodiment, preferably, the support frame 2 includes a support plate 21 and an angle steel 22. The angle steel 22 is fixedly installed on one corner of the support plate 21, and the support plate 21 is perpendicular to the angle steel 22. One side wall of the angle steel 22 is flush with the formwork-free wall panel mold 1, and the other side wall of the angle steel 22 is flush with the upper or lower edge of the formwork-free wall panel mold 1. The angle steels 22 at corresponding positions on both sides of the formwork-free wall panel mold 1 are connected by bolts. Both ends of the support rod 3 are detachably connected to the support plate 21. Specifically, the inside corners of the support plate 21 and the angle steel 22 are connected by welding. The angle steel 22 facilitates the connection between the support frame 2 and the formwork-free wall panel mold 1, and at the same time, the angle steel 22 provides installation space for the support plate 21. In addition, the support plate 21 is provided with a lifting hole 5, which facilitates the lifting of the non-removable wall panel mold 1. At the same time, the support plate 21 is also provided with multiple bolt holes, which are used to achieve detachable connection with the bolt holes at both ends of the support rod 3 by bolts.

[0034] In the above embodiment, bolt holes are provided on both side walls of the angle steel 22. The bolt holes on the side wall flush with the formwork-free wall panel 1 are used to pass through bolts connecting the angle steel 22 on both sides of the formwork-free wall panel 1. The bolt holes on the side wall flush with the upper or lower edge of the formwork-free wall panel 1 are used to connect the formwork-free wall panel 1 to the reference panel. When the formwork-free wall panel 1 is hoisted to the required installation position, anchor bolts are installed using the bolt holes on the side wall of the angle steel 22 flush with the lower edge of the formwork-free wall panel 1, thereby fixing the formwork-free wall panel 1 to the ground and preventing the anchors of the formwork-free wall panel 1 from moving during concrete pouring. When the formwork-free wall panel 1 is used to construct a multi-story building, the angle steel 22 at the bottom of the formwork-free wall panel 1 is connected to the ground or the top plate of the next floor, while the angle steel 22 at the top of the formwork-free wall panel 1 is connected to the bottom plate of the upper floor.

[0035] In the above embodiments, preferably, the support rod 3 is a telescopic structure. The telescopic structure enables the adjustment of the support rod 3, making it suitable for different heights of the non-removable formwork wall panel mold 1. Specifically, setting the support rod 3 as a telescopic structure is prior art, and specific examples of telescopic structures in the prior art can be found. Here, no specific limitations are made on the structure of the support rod 3.

[0036] See Figure 3 and 4According to some embodiments of this utility model, when multiple non-removable mold wall panel molds 1 are spaced apart, a connecting plate 6 is also included. The connecting plate 6 is disposed between adjacent non-removable mold wall panel molds 1, and the connecting plate 6 is detachably connected to the support frame 2 on the adjacent non-removable mold wall panel mold 1 through a support rod 3. Specifically, one connecting plate 6 is disposed on each of the bottom support frame 2 and the top support frame 2 of the non-removable mold wall panel mold 1 on a horizontal plane. The connecting plate 6 is connected to the support plate 21 on the same horizontal plane through a support rod 3. In other embodiments, the upper connecting plate 6 can also be connected to the support plate 21 of the support frame 2 at the bottom of the adjacent non-removable mold wall panel mold 1 through a support rod 3 to achieve diagonal support, thereby improving the support strength of the non-removable mold wall panel mold 1.
