[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] Please see attached Figure 1 To Attachment Figure 4A formwork interception device for pouring concrete in a vertical post-casting strip comprises an interception web 1, an interception side plate 2 and a fixing member 3; two groups of interception side plates 2 are respectively arranged at both ends of the interception web 1 to form an interception plate body with a C-shaped structure; the interception web 1 is fixed on a vertical wall panel 4, and the ends of the formwork strips 5 on both sides of the post-casting strip are respectively fixed on the two groups of interception side plates 2 through the fixing members 3, so that the formwork strips 5 are fixed on the vertical wall panel 4.
[0024] Preferably, the intercepting web 1 can be made of galvanized iron sheet with a thickness of 2 mm and a width of 230 mm. The height of the intercepting web 1 is not less than the height of the template strip 5 to ensure the reinforcement effect of the template strip 5.
[0025] Preferably, the intercepting side plate 2 can be made of galvanized iron sheet with a thickness of 2 mm and a width of 100 mm. The height of the intercepting side plate 2 is consistent with the height of the intercepting web 1. The fixing part 3 can be a threaded nail. The distance between the threaded nail and the end of the intercepting side plate 2 away from the intercepting web 1 is 30 mm, and the vertical spacing of the threaded nail is 150 mm.
[0026] After the two formwork strips 5 are set up, the ends of the two formwork strips 5 are reinforced by the intercepting plate body, the intercepting side plate 2 is connected and fixed to the ends of the two formwork strips 5, and the intercepting web plate 1 is connected and fixed to the vertical wall panel 4, so that the two formwork strips 5 are relatively fixed on the vertical wall panel 4, thereby achieving the reinforcement effect and preventing the formwork strips 5 from running off when pouring concrete.
[0027] After the concrete of the post-casting zone is poured, the interception plate body can be removed synchronously with the formwork strip 5 and can be recycled.
[0028] Please see attached Figure 3 and attached Figure 4 Each group of intercepting side panels 2 is arranged in pairs, and a spacing is left between a pair of intercepting side panels 2 so that the end of the template strip 5 can be inserted between the pair of intercepting side panels 2.
[0029] By arranging the intercepting side plates 2 in pairs on both sides of the end of the template strip 5, the template strip 5 can be limited in two directions, thereby ensuring the reinforcement effect of the template strip 5 and greatly reducing the probability of the template strip 5 running off during the concrete pouring process.
[0030] Please see attached Figure 4 The spacing width of the pair of intercepting side panels 2 is consistent with the thickness of the template strip 5, so that the two end surfaces of the template strip 5 are fitted with the pair of intercepting side panels 2, and the fixing member 3 connects the end of the template strip 5 and the pair of intercepting side panels 2.
[0031] The spacing between a pair of intercepting side plates 2 can be determined according to the thickness of the template strip 5 , thereby ensuring the clamping and limiting effect of the pair of intercepting side plates 2 on the template strip 5 , and further ensuring the reinforcement effect of the template strip 5 .
[0032] Please see attached Figure 1 and attached Figure 3 The pair of intercepting side panels 2 are provided with a plurality of fixing members 3, which are vertically spaced and connected through the pair of intercepting side panels 2 and the template strips 5.
[0033] The fixing members 3 arranged at intervals vertically can improve the connection reliability between a pair of intercepting side panels 2 and the ends of the vertical formwork strips 5, so that the ends of the formwork strips 5 are subjected to uniform force and are reinforced stably.
[0034] Please see attached Figure 2 and attached Figure 4 The intercepting web 1 is provided with a steel bar groove 11 so that the steel bars 41 of the vertical wall panel 4 pass through the steel bar groove 11 and penetrate the intercepting web 1 .
[0035] The width of the steel bar groove 11 can be adaptively adjusted according to the diameter of the steel bar 41, and the position of the steel bar groove 11 on the intercepting web 1 can also be adaptively adjusted according to the position of the steel bar 41 to ensure that the steel bar 41 can penetrate the intercepting web 1 without affecting the installation and reinforcement of the intercepting web 1 at the end of the template strip 5.
[0036] Please see attached Figure 2 The steel bar through groove 11 is a vertical strip-shaped structure, and a plurality of steel bar through grooves 11 are formed on the intercepting web 1 at intervals.
[0037] The steel bar groove 11 is designed as a long strip structure, which can meet the requirements of the steel bars 41 at different heights, and can also avoid the problem of interference between the steel bars 41 and the intercepting web 1 caused by the height deviation of the steel bars 41 and the position of the steel bar groove 11.
[0038] Preferably, a spacing of 100 mm can be reserved between two vertically adjacent steel bar grooves 11, the height of each steel bar groove 11 is 400 mm, the spacing between laterally adjacent steel bar grooves 11 is 120 mm, the width of the steel bar groove 11 is 20 mm, and the spacing between the steel bar groove 11 and the edge of the intercepting web 1 is 35 mm.
[0039] A blocking net (not shown in the figure) is detachably mounted on the steel bar through-groove 11 , so that the blocking net covers the gap between the long steel bar through-groove 11 and the steel bar 41 .
[0040] The gap between the long steel bar groove 11 and the steel bar 41 is blocked by the blocking net, so that concrete can be prevented from leaking out of the gap between the steel bar groove 11 and the steel bar 41 .
[0041] Please see attached Figure 4 A back rib 6 is provided between the intercepting web 1 and the vertical wall panel 4 , and the back rib 6 and the steel bars 41 of the vertical wall panel 4 are staggered.
[0042] Since there is usually a certain gap between the intercepting web 1 and the vertical wall panel 4, a back rib 6 of corresponding thickness can be set in the gap between the intercepting web 1 and the vertical wall panel 4 to ensure that the connection between the intercepting web 1 and the vertical wall panel 4 and its steel bars 41 is firm and reliable.
[0043] Please see attached Figure 3 The interception web 1 and the two pairs of interception side plates 2 at its ends are an integrated structure, which improves the structural strength of the interception plate body.
[0044] Please see attached Figure 1 To Attachment Figure 4 The construction method of the template strip 5 for reinforcing the vertical post-casting belt by using the utility model is:
[0045] After the vertical wall panel 4 is constructed, the interception web 1 is fixed to the steel bars 41 of the vertical wall panel 4, and the steel bars 41 of the vertical wall panel 4 penetrate the steel bar grooves 11 of the interception web 1. When installing the interception board body, if the height of the interception board body is higher than the wall height, the top of the interception board body can be extended out of the top of the wall, and it is best not to cut it, so as to facilitate the turnover and reinforcement of the template strips 5 at different heights.
[0046] The formwork strip 5 of the post-casting strip is supported and preliminarily reinforced by wood and tension bolts to form the formwork system of the post-casting strip. The formwork system is supported and reinforced by conventional processes, which will not be described here. When supporting the formwork strip 5, the end of the formwork strip 5 is inserted between a pair of interception side plates 2 at the end of the interception web 1, and nailed into the fixing piece 3 for fixing. The fixing piece 3 is arranged at intervals of 150 mm along the length direction of the interception side plate 2.
[0047] A back rib 6 is arranged between the intercepting web 1 and the vertical wall panel 4 to reinforce the connection between the formwork system of the post-cast strip and the vertical wall panel 4. The gap between the steel bar 41 and the steel bar through groove 11 is blocked by a blocking net, concrete is poured on the blocking net, and after the concrete is initially set, the blocking net is promptly removed, and the two ends of the post-cast strip can be sealed by concrete to prevent concrete leakage.
[0048] When pouring concrete of the post-cast strip, concrete will not leak out from the steel bar groove 11, and the template strip 5 reinforced by the interception web 1 and the interception side plate 2 will not deviate during the concrete pouring.
[0049] After the concrete of the post-cast zone reaches a certain strength, the template strip 5 is removed, and the interception plate body is also removed at the same time. The template strip 5 and the interception plate body can be reused after being cleaned.
[0050] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
