Description

Technical Field

[0001] The present invention relates to the field of building construction, and particularly relates to a support system for a hollow floor slab box body and a construction method thereof. Background Art

[0002] Traditional hollow floor slabs mostly adopt cast-in-place concrete or precast components, and the support system is usually a temporary scaffolding or steel support. The construction is complex and time-consuming. At present, in the development of building construction, some modular support systems have been applied to building projects and used in the support system of hollow floor slab boxes to support the hollow floor slab boxes. However, the connection methods of the current support systems are mostly welding or simple bolt connections, with low installation accuracy and poor stability. Moreover, the internal cavity structure of the hollow floor slab results in insufficient overall stiffness, prone to deformation or cracking, and there is a lack of a dedicated support system for hollow floor slabs, making it difficult to meet their special force requirements.

[0003] Therefore, it is necessary to propose a support system for a hollow floor slab box body and a construction method thereof, which can evenly disperse the load and improve the overall stability. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a support system for a hollow floor slab box body and a construction method thereof.

[0005] The support system for a hollow floor slab box body and the construction method provided by the present invention adopt the following technical solutions:

[0006] A support system for a hollow floor slab box body includes multiple groups of support frames arranged at the bottom of the floor slab box body. The support frame includes a bearing part, a support column, and multiple support feet. The bearing part is spherical, the support column is vertically arranged on the bearing part to fix the floor slab box body on the bearing part, the support legs are arranged at the bottom of the bearing part and support on the floor slab of the floor, and a support beam is connected between adjacent two support legs. The support beam is located below the steel bars of the floor slab to resist buoyancy.

[0007] Further, a clamping assembly is arranged at the top of the support column, and the clamping assembly is used to clamp and fix the edges of the upper and lower covers of the floor slab box body.

[0008] Further, the clamping assembly includes a fixed clamping part, a connecting column vertically arranged on one side of the fixed clamping part, and a clamping plate whose one end is arranged to move up and down on the connecting column. The clamping plate can rotate on the support column, and the clamping plate can be pressed against the top of the upper cover of the floor slab box body and cooperate with the fixed clamping part to fix the floor slab box body.

[0009] Further, a locking cap for pressing the clamping plate against the top of the upper cover of the floor slab box body is threadedly sleeved on the connecting column.

[0010] Further, a sliding sleeve for sliding on the connecting column is provided at the bottom of the clamping plate.

[0011] Further, the fixed clamping part is detachably arranged on the support column.

[0012] Further, both the support column and the support feet are detachably arranged on the bearing part.

[0013] A construction method for the support body of a hollow floor slab box body includes the following steps:

[0014] S1. Install the support column and the support feet on the bearing part and place them at the construction position required according to the construction drawings.

[0015] S2. Weld the support beams between the support legs in sequence and make the support beams under the steel bars of the bottom plate.

[0016] S3. Install the clamping assembly and fixedly install the fixed clamping part on the support column.

[0017] S4. Place the floor slab box body, rotate the clamping plate so that the edge of the floor slab box body can be placed on the fixed clamping part. After determining that each fixed clamping part supports the bottom of the edge of the floor slab box body, move the clamping plate above the edge of the floor slab box body, rotate the clamping plate onto the edge of the floor slab box body, tighten the locking nut downward to press the clamping plate against the edge of the floor slab box body, and clamp and fix the floor slab box body.

[0018] In summary, the present invention includes at least one of the following beneficial effects:

[0019] 1. By fixing and supporting the four edges of the floor slab box body through the support frame, the problems of unreliable support, poor stability, poor bearing capacity, and easy deformation under force of the support body of the hollow floor slab box body can be effectively solved, meeting the requirements of the complex construction site environment.

[0026] The following combines the attached Figure 1-2 to further elaborate on the present invention in detail.

[0027] The embodiment of the present invention discloses a support system for a hollow floor slab box body and its construction method. Referring to Figures 1-2 , the support system for the hollow floor slab box body includes multiple groups of support frames arranged at the bottom of the floor slab box body. The support frame includes a bearing part 1, a support column 2, and multiple support feet 3. The support column 2 is vertically arranged on the bearing part 1 to fix the floor slab box body on the bearing part 1, and the support leg 3 is arranged at the bottom of the bearing part 1 to support on the floor slab of the floor. By fixing and supporting the four edges of the floor slab box body through the support frame, the problems of unreliable support, poor stability, poor bearing capacity, and easy deformation under force of the support body of the hollow floor slab box body can be effectively solved, meeting the requirements of the complex construction site environment.

[0028] In this embodiment, a support beam 4 is connected between two adjacent support legs 3. The support beam 4 is located below the steel bars of the floor slab to resist buoyancy. By arranging the support beam 4 on the support leg 3 and the support beam 4 being below the steel bars of the floor slab, the problem of the floor slab box body floating during concrete pouring can be solved, and the floor slab box body can be limited.

[0029] In this embodiment, a clamping assembly 5 is arranged at the top of the support column 2. The clamping assembly 5 is used to clamp and fix the edges of the upper and lower covers of the floor slab box body. The clamping assembly 5 includes a fixed clamping part 51, a connecting column 52 vertically arranged on one side of the fixed clamping part 51, and a clamping plate 53 whose one end is arranged to move up and down on the connecting column 52. The clamping plate 53 can rotate on the support column 2, and the clamping plate 53 can be pressed against the top of the upper cover of the floor slab box body to cooperate with the fixed clamping part 51 to fix the floor slab box body. When installing the floor slab box body, hoist the floor slab box body to the construction position, align the edge of the floor slab box body with the fixed clamping part 51, place the floor slab box body on the fixed clamping part 51, press the clamping plate 53 against the upper part of the floor slab box body to fix the floor slab box body. Through the cooperation of the clamping plate 53 and the fixed clamping part 51, the positioning is easier when installing the floor slab box body, there is no need to drill holes in the floor slab box body, which will not affect the overall strength of the floor slab box body, and the installation is also easier.

[0030] In this embodiment, a locking cap 54 is threadedly sleeved on the connecting column 52 for pressing the clamping plate 53 against the top of the upper cover of the floor slab box body. After moving the clamping plate 53 above the floor slab box body, by screwing down the locking cap 54, the clamping plate 53 is pressed against the floor slab box body during the downward screwing process of the locking cap 54, and the floor slab box body is locked and fixed.

[0031] In this embodiment, a sliding sleeve 55 for sliding on the connecting column 52 is provided at the bottom of the clamping plate 53. The sliding sleeve 55 can increase the stability of the up-and-down movement of the clamping plate 53, making the clamping plate 53 press more firmly on the floor slab box body.

[0032] In this embodiment, the fixed clamping part 51 is detachably arranged on the support column 2. A threaded hole is provided at the bottom of the fixed clamping part 51, and the fixed clamping part 51 is installed on the support column 2 by threaded cooperation with the support column 2, which is convenient for the installation and disassembly of the fixed clamping part 51.

[0033] In this embodiment, the bearing part 1 is arranged in a spherical shape. The support column 2 and the support feet 3 are both detachably arranged on the bearing part 1. The bearing part 1 arranged in a spherical shape occupies less space, and at the same time, the received bearing capacity is concentrated at the center of gravity of the sphere, and the force is more concentrated.

[0034] A construction method for a support body of a hollow floor slab box body includes the following steps:

[0035] Step 1: Install the support column 2 and the support feet 3 on the bearing part 1 and place them at the construction position according to the construction drawings;

[0036] Step 2: Weld the support beams 4 between the support legs 3 in sequence and make the support beams 4 under the steel bars of the bottom plate;

[0037] Step 3: Install the clamping assembly 5 and fixedly install the fixed clamping part 51 on the support column 2;

[0038] Step 4: Place the floor slab box body, rotate the clamping plate 53 so that the edge of the floor slab box body can be placed on the fixed clamping part 51. After determining that each fixed clamping part 51 supports the bottom of the edge of the floor slab box body, move the clamping plate 53 above the edge of the floor slab box body, rotate the clamping plate 53 onto the edge of the floor slab box body, and tighten the locking cap 54 downward to press the clamping plate 53 against the edge of the floor slab box body to clamp and fix the floor slab box body.
