Description

Technical Field

[0001] This utility model relates to the field of early formwork removal technology, and specifically to a support structure for early formwork removal of post-pouring strips. Background Technology

[0002] During basement roof slab construction, the post-cast strip is often poured relatively late in the project. To ensure the structural stability of the roof slab, the supporting structure must not be removed before or after the post-cast strip is closed. This results in numerous pre-installed supports and formwork for the post-cast strip, which takes a long time, especially for settlement-related post-cast strips, often exceeding six months. This leads to waste of formwork and support materials. Furthermore, because the linear supports traverse the basement, internal traffic is obstructed, horizontal material transport is hindered, and turnover efficiency is low. It also affects the insertion of subsequent construction processes. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a support structure for early removal of formwork for post-pouring strips. By setting support rods on both sides of the post-pouring strip, the support rods can support the position of the post-pouring strip, thereby facilitating the removal of other support structures of the concrete structure by construction personnel, thus ensuring that the remaining parts of the building structure can continue to be constructed.

[0004] The technical solution to achieve the above objective is a support structure for early removal of formwork for post-cast strips, wherein the post-cast strip is formed between two concrete structural parts, and the support structure includes:

[0005] Several pads are embedded in the concrete structure on both sides of the post-cast strip and are set close to the post-cast strip. The bottom surface of the pad is flush with the bottom surface of the corresponding concrete structure, and the bottom surface of the pad is exposed on the bottom surface of the corresponding concrete structure for connecting the post-cast strip template.

[0006] The support rods corresponding to the pads are arranged vertically. One end of the support rod passes through the corresponding pad and is embedded in the corresponding concrete structure part, while the other end of the support rod is supported on the structure below the post-cast strip.

[0007] Furthermore, a fixing screw is also provided on the pad, one end of which is embedded in the corresponding concrete structure part, and the other end of which is located below the bottom surface of the pad to form a template connection section.

[0008] Furthermore, the pad has a through hole corresponding to the fixing screw, and the fixing screw passes through the through hole.

[0009] Furthermore, each of the pads is provided with at least two fixing screws, and the fixing screws are staggered from the support rods.

[0010] Furthermore, a fixing nut is detachably provided on the template connecting section, and the post-pouring strip template is fixed by screwing on the fixing nut.

[0011] Furthermore, several of the pads are spaced apart along the setting direction of the post-cast strip.

[0012] Furthermore, each of the pads is provided with at least one of the support rods.

[0013] Furthermore, the support rod is fixed to the structure located below the post-cast strip by expansion bolts.

[0014] Furthermore, the support rod is fixed to the structure located below the post-cast strip by welding.

[0015] Furthermore, the support rod is made of I-beams.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] By installing support rods on both sides of the post-pouring strip, the support rods can support the position of the post-pouring strip, which makes it easier for construction workers to dismantle other supporting structures of the concrete structure, thus ensuring that the rest of the building structure can continue to be constructed.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] See Figure 1 A support structure for early removal of formwork for post-pouring strips is disclosed. The post-pouring strip is formed between two concrete structural parts. The support structure is set between two floor slabs of a building, one above the other. The post-pouring strip is formed on the top floor slab. Preferably, in this embodiment, the support structure is set between the top slab 1 and the raft slab 2 of the building. A top slab post-pouring strip 4 is formed on the top slab 1. The support structure includes: a plurality of pads 6 embedded in the top slab 1, the pads 6 being arranged opposite each other on both sides of the top slab post-pouring strip 4, the surface of the pads 6 being flush with the bottom surface of the top slab 1, and a post-pouring strip formwork being set between two opposite pads; and a support rod 3 vertically set between the top slab 1 and the raft slab 2 and corresponding to the setting position of the pads 6, the end of the support rod 3 passing through the pads 6 and embedded in the top slab 1, and the end of the support rod 3 away from the pads 6 being fixedly installed on the raft slab 2.

[0029] Furthermore, a raft slab post-cast strip is formed on the raft slab 2. The raft slab post-cast strip and the top slab post-cast strip 4 are arranged opposite each other. By arranging the top slab post-cast strip 4 and the raft slab post-cast strip opposite each other, the construction steps are reduced, thereby speeding up the construction process.

[0030] In this utility model, a preferred embodiment is as follows: Before pouring the top slab 1, the support rod 3 is erected at the position of the post-pouring strip. The support rod 3 is temporarily fixed on the support frame of the pouring template of the top slab 1 by steel wire rope, and the length of the support rod 3 is controlled. Preferably, the portion of the support rod 3 inside the top slab 1 is 3-5 cm. The bottom of the support rod 3 is fixedly connected to the raft slab 2. The pouring template of the top slab 1 is laid, and the pouring template is assembled by a splicing method. The pad 6 is set on the support rod 3. To ensure the stress on the I-beam, the pad 6 can be... The post-pouring strip is slightly arched. The top slab 1 is poured on the pouring template, and the position of the post-pouring strip is reserved. After the top slab 1 reaches the required curing time, the pouring template and support frame are removed normally, and the post-pouring strip is protected accordingly. Subsequent work can proceed normally. When the post-pouring strip reaches the sealing condition, the post-pouring strip position of the top slab 1 is sealed by installing the post-pouring strip template 7 on the support rod 3. The use of a climbing vehicle is sufficient and no additional scaffolding is required. After reaching the required strength, the post-pouring strip template 7 is removed normally. During template removal, some of the support rods 3 are cut off. After cutting off, the exposed part of the pad plate 6 is treated with rust prevention and then smoothed with mortar.

[0031] Furthermore, a plurality of fixing screws 5 are embedded in the top plate 1. Part of the fixing screws 5 pass through the pad 6 to form a template connecting section. The post-pouring strip template 7 is detachably installed on the template connecting sections of the two oppositely arranged pads 6. Preferably, the post-pouring strip template 7 has threaded holes corresponding to the template connecting sections. The post-pouring strip template 7 is placed at the bottom of the top plate 1. By passing the template connecting section through the threaded hole, the post-pouring strip template 7 can slide up and down along the template connecting section. A fixing nut is threadedly connected to the template connecting section. The fixing nut is located at the bottom of the post-pouring strip template 7. By screwing the fixing nut, the bottom surface of the post-pouring strip template 7 and the top surface of the fixing nut are brought into contact. By continuing to screw the fixing nut, the fixing nut pushes the post-pouring strip template 7, so that both sides of the post-pouring strip template 7 are tightly pressed against the bottom of the top plate 1.

[0032] Furthermore, the pad 6 has a through hole corresponding to the fixing screw 5, and the fixing screw 5 passes through the through hole. Preferably, when casting the top slab 1, a portion of the fixing screw 5 is first embedded in the casting template, and then passes through the through hole of the pad 6 to be placed at the bottom of the top slab 1.

[0033] Furthermore, after the post-pouring strip is poured, the post-pouring strip formwork 7 is removed, and the screws and support rods 3 exposed at the bottom of the top slab 1 are removed until the surface of the pad 6 is flush with the bottom of the top slab 1, thereby increasing the aesthetics of the top slab 1. After the removal is completed, the pad 6 is treated with rust prevention. Preferably, the same mortar as the top slab 1 can be applied to make the top slab 1 look aesthetically pleasing.

[0034] Furthermore, the support rod 3 is fixed to the raft plate 2 by expansion screws.

[0035] Furthermore, the support rod 3 is fixed to the raft 2 by welding.

[0036] Furthermore, the support rod 3 is made of I-beams.

[0037] Furthermore, a number of connecting steel bars are provided within the post-cast strip of the raft slab. By providing connecting steel bars within the post-cast strip, the strength of the post-cast strip is improved after casting.

[0038] Furthermore, a number of supporting reinforcing bars are provided within the post-pouring strip 4 of the top slab. By providing supporting reinforcing bars within the post-pouring strip 4 of the top slab, the strength of the post-pouring strip is improved after pouring.

[0039] Furthermore, the distance between two adjacent support rods 3 is determined according to the on-site construction requirements.

[0040] Furthermore, the pads are spaced apart along the extension direction of the post-cast strip.

[0041] Furthermore, the number of support rods 3 is determined according to the on-site construction requirements.

[0042] The following describes the usage process of the present invention for an early removal support structure for post-pouring strip formwork.

[0043] Before pouring the top slab 1, the support rod 3 is erected at the location of the post-pouring strip. The support rod 3 is temporarily fixed to the support frame of the pouring template of the top slab 1 using steel wire ropes. The length of the support rod 3 is controlled; preferably, the portion of the support rod 3 embedded within the top slab 1 is 3-5 cm. The bottom of the support rod 3 is fixedly connected to the raft slab 2. The pouring template of the top slab 1 is then laid out using a splicing method. The pad 6 is placed on the support rod 3. To ensure the H-beams bear the load, the post-pouring strip area can be slightly arched. The top slab 1 is poured on the casting template, and the position of the post-pouring strip is reserved. After the top slab 1 reaches the required curing time, the casting template and support frame are removed normally, and the post-pouring strip is protected accordingly. Subsequent work can proceed normally. When the post-pouring strip reaches the sealing condition, the post-pouring strip position of the top slab 1 is sealed by installing the post-pouring strip template 7 on the support rod 3. The use of a climbing vehicle is sufficient and no additional scaffolding is required. After the strength is reached, the post-pouring strip template 7 is removed normally. During the template removal, some of the support rods 3 are cut off. After cutting off, the exposed part of the pad plate 6 is treated with rust prevention and then smoothed with mortar.

Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
