Description

Technical Field

[0001] The utility model relates to the technical field of house construction, in particular to a prefabricated cushion block used for supporting a top plate and a roof. Background Art

[0002] In housing construction projects, the basement top plate and the main building, the roof and the protruding roof structure are usually designed with high and low spans, and cantilever plates are usually designed at the high span position; in order to ensure the integrity of the structure, the high and low spans are cast at one time. The supporting poles of the cantilever plate will fall directly on the top plate and the roof, resulting in a hole after the poles are removed later, which poses a greater risk of leakage; the construction industry attaches great importance to the waterproofing and anti-leakage of residential buildings, and now creates a prefabricated pad for the top plate and roof support, so as to achieve effective waterproofing requirements and reduce costs and increase efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a prefabricated pad for supporting a top plate and a roof. Before the top plate and the roof are cast, the prefabricated pad is installed therein and cast together to form a support column for supporting a cantilever plate, so that a better anti-leakage effect can be achieved after the position of the support column is removed.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A prefabricated pad for top plate and roof support, comprising a prefabricated concrete part, steel bars and a rubber waterstop, wherein the rubber waterstop is fixed to the middle part of the prefabricated concrete part, the size of the rubber waterstop is larger than the cross-sectional size of the prefabricated concrete part, and a plurality of the steel bars are respectively arranged on both sides of the rubber waterstop and fixedly connected to the prefabricated concrete part.

[0006] The cross section of the prefabricated concrete part is square.

[0007] The steel bars are symmetrically arranged on both sides of the rubber water stop.

[0008] There are two groups of steel bars on one side of the rubber water stop, and the two groups of steel bars are arranged perpendicular to each other.

[0009] Each group of steel bars consists of two steel bars, which are arranged parallel to each other.

[0010] The steel bars are used to be connected to the top plate or roof steel bars, and the diameter specifications are the same as the diameter specifications of the top plate or roof steel bars used for installation.

[0011] The overall thickness of the precast concrete part is the same as the thickness of the top plate or roof for installation.

[0012] The installation position of the prefabricated pad on the top plate and the roof is the supporting position of the cantilever plate supporting pole.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] A prefabricated pad for supporting a top plate and a roof. Before the top plate and the roof are cast, the prefabricated pad is installed therein and cast together to form a support column for supporting a cantilever plate. After the position of the support column is removed, the prefabricated pad can have a better anti-leakage effect, reduce secondary floor leakage, and improve the quality of the building.

[0019] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0020] See Figure 1-Figure 3 A prefabricated pad for top plate and roof support, including a prefabricated concrete part 3, a steel bar 1, and a rubber waterstop 2. The rubber waterstop 2 is fixed to the middle part of the prefabricated concrete part 3. The size of the rubber waterstop 2 is larger than the cross-sectional size of the prefabricated concrete part 3. A plurality of steel bars 1 are respectively arranged on both sides of the rubber waterstop 2 and fixedly connected to the prefabricated concrete part 3.

[0021] The cross section of the prefabricated concrete part 3 is square.

[0022] The steel bars 1 are symmetrically arranged on both sides of the rubber water stop 2 .

[0023] There are two groups of steel bars 1 on one side of the rubber water stop 2, and the two groups of steel bars 1 are arranged perpendicular to each other.

[0024] Each group of steel bars 1 consists of two steel bars, which are arranged parallel to each other.

[0025] The steel bar 1 is used to connect with the top plate or roof steel bar, and the diameter specification is the same as the diameter specification of the top plate or roof steel bar used for installation.

[0026] The overall thickness of the prefabricated concrete part 3 is the same as the thickness of the top plate or roof for installation.

[0027] The installation position of the prefabricated pad on the top plate and the roof is the supporting position of the cantilever plate supporting pole.

[0028] The manufacturing method of the utility model is as follows:

[0029] 1. Construction preparation:

[0030] 1) Technical preparation: Check the drawings in advance to understand the slab thickness, concrete strength, steel bar diameter and other information at the corresponding location;

[0031] 2) Site preparation: steel bars 1, waste formwork, concrete (strength consistent with the building's top plate and roof), release agent, rubber waterstop 2;

[0032] 2. Production: Make two wooden mold boxes with reserved holes for steel bars in the boxes. Apply release agent and install the binding steel bars 1. Pour concrete in the bottom wooden mold box, put in a rubber waterstop 2 that expands when exposed to water, place the upper wooden mold box on the upper end of the rubber waterstop 2, continue pouring concrete, and then vibrate and cure after the pouring is completed.

[0033] When using:

[0034] Before pouring the top plate and roof, install the prefabricated pads in the top plate and roof steel cage. The installation position is the supporting position of the cantilever plate support pole. After the top plate and roof are poured and the concrete reaches the strength, it can be used as a supporting pad in construction. The prefabricated pads need to be slightly roughened on all sides when used.
