A removable formwork for concrete compartmentalization

Abstract

A non-removable formwork for concrete compartmenting and jointing includes main reinforcement bars, comprising: several vertically arranged vertical square steel bars with spacing between adjacent bars, the main reinforcement bars passing through the spacing; a grout-stopping mesh on the sidewalls of the vertical square steel bars; a transverse square steel bar at the rear end of the vertical square steel bars; a first auxiliary reinforcement bar fixed to the vertical and transverse square steel bars; and a second auxiliary reinforcement bar fixed to the main reinforcement bars. The spacing is wider than the diameter of the main reinforcement bars, allowing the main reinforcement bars to pass directly through the spacing during installation without needing to drill holes or cut the reinforcement bars in the formwork, thus improving work efficiency and the safety of the concrete components. After one side of the grout-stopping mesh is poured and initially set, concrete is poured in the direction of the transverse square steel bars. The concrete then wraps around both sides of the vertical and transverse square steel bars, forming joints at the vertical square steel bars. This eliminates the need to remove the vertical and transverse square steel bars, improving construction efficiency, and the vertical square steel bars reinforce the joints, making them less prone to damage.

Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, and more specifically, to a non-removable formwork for concrete compartmenting and jointing. Background Technology

[0002] The dust-separation method is mainly used when pouring large volumes of concrete, such as grouting slabs. This method primarily controls concrete shrinkage cracks and temperature stress by dividing large volumes of concrete into smaller construction units through pre-set gaps, thus reducing shrinkage deformation and temperature effects. To maintain the integrity of the grouting slab, the reinforcement construction joints cannot be cut off; using ordinary formwork would require creating holes for the reinforcement, resulting in low construction efficiency. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a non-removable formwork for concrete compartmenting and jointing. It can use a grout-stopping mesh, square steel pipes, and steel reinforcement as the formwork system. It prevents grout leakage during concrete pouring and does not need to be removed after construction, thus accelerating the construction progress.

[0004] A non-removable formwork for concrete compartmenting and jointing includes main reinforcement, comprising: a plurality of vertically arranged vertical square steel bars, with a spacing between adjacent vertical square steel bars, the main reinforcement passing through the spacing; a grout-stopping mesh provided on the side wall of the vertical square steel bars; a transverse square steel bar provided at the rear end of the vertical square steel bars; a first auxiliary reinforcement bar fixed to the vertical square steel bars and the transverse square steel bars; and a second auxiliary reinforcement bar fixed to the main reinforcement.

[0005] Furthermore, the height of the vertical square steel is greater than the thickness of the concrete pouring, and the top surface of the vertical square steel is located above the completed concrete pouring surface.

[0006] Furthermore, an elevation control line is provided on the upper part of the vertical square steel.

[0007] Furthermore, the grout-stopping mesh has fine holes in the middle, and the grout-stopping mesh is made of fine iron wire. The grout-stopping mesh is bound to the vertical square steel by iron wire.

[0008] Furthermore, the grout-stopping mesh covers the spacing, and the main reinforcement bar penetrates the grout-stopping mesh.

[0009] Furthermore, the horizontal square steel spans multiple vertical square steels, adjacent horizontal square steels overlap each other, the horizontal square steels are connected by binding wire, and the horizontal square steels and the vertical square steels are also connected by binding wire.

[0010] Furthermore, the transverse square steel and the grout-stopping mesh are located on the opposite side walls of the vertical square steel, with the grout-stopping mesh facing the direction of concrete pouring.

[0011] Furthermore, the first auxiliary rib is provided on both sides of the vertical square steel, the first auxiliary rib is inclined, and the bottom of the first auxiliary rib supports the surface of the base layer.

[0012] Furthermore, the bottom of the second auxiliary reinforcement contacts the base layer, the second auxiliary reinforcement penetrates the double-layer main reinforcement, and the second auxiliary reinforcement is welded to the main reinforcement.

[0013] Furthermore, the second auxiliary rib is disposed on one side of the transverse square steel, and the second auxiliary rib is attached to the transverse square steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] ① The width of the spacing is greater than the diameter of the main reinforcement, so the main reinforcement can be directly passed through the spacing when it is installed, without the need to drill holes in the formwork or cut the reinforcement, which improves work efficiency and the safety of concrete components.

[0016] ② After the grout-stopping mesh is poured and initially set on one side, concrete is poured in the direction of the horizontal square steel. The concrete then wraps around both sides of the vertical square steel and the horizontal square steel, forming a joint at the vertical square steel. This eliminates the need to remove the vertical and horizontal square steel, improving construction efficiency. Furthermore, the joint is reinforced by the vertical square steel, making it less prone to damage. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] like Figure 1 , Figure 2 As shown, a non-removable formwork for concrete compartmenting and jointing includes a main reinforcement 1, comprising: a plurality of vertically arranged vertical square steel bars 2, with a spacing 21 between adjacent vertical square steel bars 2, and the main reinforcement 1 passing through the spacing 21; a grout-stopping mesh 3 provided on the side wall of the vertical square steel bars 2; a transverse square steel bar 4 provided at the rear end of the vertical square steel bars 2; a first auxiliary reinforcement 5 fixed to the vertical square steel bars 2 and the transverse square steel bars 4; and a second auxiliary reinforcement 6 fixed to the main reinforcement 1.

[0023] Before binding the main reinforcement 1 of the grouting cover plate, install the vertical square steel 2 and the horizontal square steel 4 in place according to the measured and laid-out position, and then lay and bind the main reinforcement 1.

[0024] The width of the spacing 21 is greater than the diameter of the main reinforcement 1, so the main reinforcement 1 can be directly passed through the spacing 21 when it is installed, without the need to drill holes in the formwork or cut the reinforcement, which improves work efficiency and the safety of concrete components.

[0025] The height of the vertical square steel 2 is greater than the thickness of the concrete pouring. The top surface of the vertical square steel 2 is located above the finished concrete surface. After the concrete pouring is completed, the top of the vertical square steel 2 is exposed above the finished concrete surface. After the concrete has solidified, use tools such as a corneal cutter to cut and level the excess vertical square steel 2. If the base layer is soil, the bottom of the vertical square steel 2 can be inserted into the base layer for simple fixation. If it cannot be inserted, bricks can be used for simple temporary clamping and fixation.

[0026] An elevation control line 22 is installed on the upper part of the vertical square steel 2. The elevation control line 22 is positioned on the vertical square steel 2 using a level and a total station, and then fixed on the vertical square steel 2 by painting or applying strips. The elevation control line 22 is 30 or 50 centimeters above the finished concrete surface. The height is measured with a ruler when the concrete is almost finished pouring to achieve elevation control.

[0027] The grout-stopping mesh 3 is used to seal the gap 21, reducing and preventing a large amount of concrete from flowing out from the gap 21. The grout-stopping mesh 3 has fine holes in the middle. The grout-stopping mesh 3 is made of fine iron wire. The use of fine iron wire has a certain toughness and strength, which can effectively intercept concrete and is not easily damaged.

[0028] The grout-stopping mesh 3 has a coverage spacing of 21 to prevent grout leakage. The main reinforcement 1 is laid after the grout-stopping mesh 3 is installed. During the laying of the main reinforcement 1, the main reinforcement 1 penetrates the grout-stopping mesh 3, and the grout-stopping mesh 3 can be penetrated by the main reinforcement 1. In actual construction, a small amount of concrete grout may leak out from the small holes, but this small amount of leakage will not affect normal construction. The grout-stopping mesh 3 is tied to the vertical square steel 2 with iron wire. The iron wire can penetrate the grout-stopping mesh 3, and multiple iron wires are tied together to prevent the grout-stopping mesh 3 from being impacted by concrete, thereby ensuring the grout-stopping effect.

[0029] The horizontal square steel 4 is used to connect and fix adjacent vertical square steel 2. One horizontal square steel 4 spans multiple vertical square steel 2, and adjacent horizontal square steel 4 overlap each other, so that the overall length of the horizontal square steel 4 is the same as the concrete pouring range. The horizontal square steel 4 are connected by binding wire, and the horizontal square steel 4 and the vertical square steel 2 are also connected by binding wire. The horizontal square steel 4 and the vertical square steel 2 are connected into a whole by the wire, thereby strengthening the overall strength and preventing the vertical square steel 2 from falling apart during concrete pouring.

[0030] The horizontal square steel 4 and the grout-stopping mesh 3 are installed on opposite sides of the vertical square steel 2, with the grout-stopping mesh 3 facing the direction of concrete pouring. During concrete pouring, the concrete impacts the grout-stopping mesh 3 and the side walls of the vertical square steel 2 in the direction of the grout-stopping mesh 3. The horizontal square steel 4 reinforces the resistance of the vertical square steel 2 at its rear end. After one side of the grout-stopping mesh 3 is poured and initially set, concrete is poured in the direction of the horizontal square steel 4. The concrete thus encloses both sides of the vertical square steel 2 and the horizontal square steel 4, forming a joint at the vertical square steel 2. This eliminates the need to remove the vertical square steel 2 and the horizontal square steel 4, improving construction efficiency. Furthermore, the joint is reinforced by the vertical square steel 2, making it less prone to damage.

[0031] The first auxiliary rib 5 is located on both sides of the vertical square steel 2. The first auxiliary rib 5 is inclined and its bottom supports the base surface. The top of the first auxiliary rib 5 is welded to the side wall of the vertical square steel 2 and the horizontal square steel 4. The first auxiliary rib 5 supports the vertical square steel 2, thereby preventing the vertical square steel 2 from tilting.

[0032] After the main reinforcement 1 is installed, the second auxiliary reinforcement 6 is installed. The bottom of the second auxiliary reinforcement 6 contacts the base layer. The second auxiliary reinforcement 6 is vertically positioned and penetrates through the double-layer main reinforcement 1. The second auxiliary reinforcement 6 is welded to the main reinforcement 1. The second auxiliary reinforcement 6 and the transverse square steel 4 are located on one side, with the second auxiliary reinforcement 6 fitting snugly against the transverse square steel 4. The second auxiliary reinforcement 6 helps the vertical square steel 2 and the transverse square steel 4 resist the impact of concrete and prevents the vertical square steel 2 from tilting.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
