Description

Technical Field

[0001] The invention belongs to the field of construction, and in particular to a combined steel structure supporting device for beams and slabs in a cantilevered section of a post-cast strip and a construction method thereof. Background Art

[0002] Currently, the traditional method for supporting cantilevered beams and slabs in post-cast strips is to retain the formwork support system in the post-cast strip area. While this method can support cantilevered beams and slabs in post-cast strips, the long retention period of the post-cast strips leads to a low turnover rate of formwork and scaffolding. This practice results in a long-term backlog of formwork, steel pipes, timber, and other materials in the support system, increasing construction costs and even preventing formwork turnover.

[0003] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the above-mentioned prior art and provide a combined steel structure support device for cantilevered beams and slabs of post-cast strips and a construction method thereof. The structure has the characteristics of fast construction speed, convenient construction, cost saving, safety and convenience, and little impact from the site.

[0005] The combined steel structure support device includes a support column assembly, a pad stone, and a directional support assembly;

[0006] The directional support assembly is composed of an upper pad, a lower pad and an intermediate elastic support, and an intermediate splint-type rubber support;

[0007] The height of the support column assembly is adjustable. The support column assembly is arranged on a construction surface. The pad stone is arranged on the top of the support column assembly. The directional support assembly is arranged between the pad stone and the beam plate.

[0008] In some embodiments, the upper pad and the lower pad are stainless steel plates, and the middle elastic support is a plate-type rubber support.

[0009] In some embodiments, the pad stone is a plain concrete block and is disposed on the top of the support column assembly.

[0010] In some embodiments, the support column assembly includes a bottom pad, a steel column, a screw, an adjuster, and a top support plate.

[0011] The construction method of the combined steel structure support device comprises the following steps:

[0012] Step 1: Locate the cantilever beam position of the post-cast strip according to the construction drawings. According to the position of the cantilever beam of the post-cast strip, determine the position and quantity of the combined steel structure support device in the drawings;

[0013] Step 2: A hole is set at 100 mm from the end of the bottom formwork of the cantilevered beam of the post-casting belt, and the hole is used to accommodate the upper pad;

[0014] Step 3: Erect a scaffolding for installing and positioning the combined steel structure support device. After the scaffolding is erected, determine the installation position of the combined steel structure support device according to the positioning dimensions in the drawing, and fix the support column assembly;

[0015] Step 3: Making a pad stone template on the top of the support column assembly and pouring the pad stone;

[0016] Step 4: After reaching a predetermined strength, the directional support assembly is placed on top of the pad stone;

[0017] Step 5: Pour concrete on both sides of the post-casting strip. After the concrete settlement on both sides of the post-casting strip reaches the design requirements, bend all the steel bars upwards, chisel them and clean up the garbage. Then, connect the steel bars on both sides of the post-casting strip through an extrusion sleeve, and finally pour the concrete of the post-casting strip.

[0018] By adopting the above technical solution, the present invention has the following technical effects:

[0019] 1. The post-casting zone position formwork system of the present invention can be dismantled in advance to avoid material backlog and increase material turnover rate;

[0020] 2. The present invention utilizes directional support components and pad stones to allow a small amount of deformation of the post-cast strip during the support process, thereby reducing the risk of cracking and leakage of the post-cast strip in the later stage;

[0021] 3. The steel bars of the post-cast strip of the present invention are all disconnected, which can ensure the chiseling effect on the side of the post-cast strip and reduce the risk of leakage at the post-cast strip. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Reference Attachment Figure 1-4 As shown, the combined steel structure support device includes a support column assembly 1, a pad stone 2, and a directional support assembly 3;

[0031] The directional support assembly 3 is composed of an upper pad 31, a lower pad 32 and an intermediate elastic support 33, an intermediate splint-type rubber support;

[0032] The height of the support column assembly 1 can be adjusted. The support column assembly 1 is set on the construction surface, the pad stone 2 is set at the top of the support column assembly 1, and the directional support assembly 3 is set between the pad stone 2 and the beam plate.

[0033] By adopting the support column assembly 1, it can be dismantled in advance, avoiding material backlog and increasing material turnover rate; by adopting the combined support form of the pad stone 2 and the directional assembly, a small amount of deformation of the post-cast strip is allowed during the support process, reducing the risk of cracking and leakage of the post-cast strip in the later stage.

[0034] In order to facilitate reuse and demoulding, the upper pad 31 and the lower pad 32 are stainless steel plates, and the middle elastic support 33 is a plate-type rubber support.

[0035] The pad stone 2 is a plain concrete block and is arranged on the top of the support column assembly.

[0036] The support column assembly 1 includes a bottom plate 11, a steel column 12, a lead screw 13, an adjuster 14, and a top support plate 15. The bottom plate 11 is connected to the bottom of the steel column 12 by welding. The upper section of the steel column 12 is provided with an internal thread. The lead screw 13 is connected to the steel column 12 by a thread. The adjuster 14 is sleeved on the lead screw 13 and is used to adjust the length of the support column assembly 1.

[0037] The construction method of the combined steel structure support device comprises the following steps:

[0038] Step 1: Locate the cantilever beam position of the post-cast strip according to the construction drawings. According to the position of the cantilever beam of the post-cast strip, determine the position and quantity of the combined steel structure support device in the drawings;

[0039] Step 2: A hole is provided at a position 100 mm away from the end of the bottom formwork of the cantilevered beam of the post-casting strip, the hole being used to accommodate the upper pad 31;

[0040] Step 3: erecting a scaffolding for installing and positioning the combined steel structure support device. After the scaffolding is erected, determine the installation position of the combined steel structure support device according to the positioning dimensions in the drawing, and fix the support column assembly 1;

[0041] Step 3: Make a template for the pad stone 2 on the top of the support column assembly 1 and cast the pad stone 2;

[0042] Step 4: After reaching the predetermined strength, the upper pad 31, the lower pad 32 and the middle elastic support 33 are sequentially arranged on top of the pad stone 2;

[0043] Step 5: Pour concrete on both sides of the post-casting strip. After the concrete settlement on both sides of the post-casting strip reaches the design requirements, bend all the steel bars upward, chisel them and clean up the garbage. Then, connect the steel bars on both sides of the post-casting strip through the extrusion sleeve 4, and finally pour the post-casting strip concrete.

[0044] In the above process, a closing net 6 and a water-stop steel plate 5 are set at the post-pouring zone. When the closing net 6 and the water-stop steel plate 5 are used for pouring structural concrete, the skeleton of the closing net 6 is at right angles to the supporting device. The skeleton of the closing net 6 must face the side where the concrete is to be poured. The junction of the water-stop steel plate 5 is connected by double-sided welding to prevent water seepage in the later stage.

[0045] The steel bars of the post-cast strip are connected through an extruded sleeve 4 to prevent deformation of the steel bars during the settlement of the post-cast strip. When a small amount of deformation occurs, the combined support form of the pad stone 2 and the directional component allows a small amount of deformation of the post-cast strip during the support process, reducing the risk of cracking and leakage of the post-cast strip in the later stage.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
