AI Technical Summary

Technical Problem

In the construction environment, temporary support for the top joists is difficult to achieve, especially in scenarios where there are stairs blocking the side and trenches in the floor slab at the bottom. Existing technology cannot effectively fix the top joists.

Method used

Steel pipe guardrails are fixedly connected to vertical and horizontal pipes using scaffolding steel pipe couplers to form keel supports. The top keel is temporarily supported by the clamps and arm support structure of the keel supports, and the top beam is fixed with bolts, thus solving the problem of temporary support for the top keel.

Benefits of technology

It achieved stable temporary support and fixation of the top keel in complex construction environments, ensuring the smooth progress of the spraying process.

Description

Technical Field

[0001] This utility model relates to a top keel installation structure for phosphogypsum sprayed walls, belonging to the field of wall construction technology. Background Technology

[0002] When constructing a phosphogypsum keel wall using spraying, the keel must be fixed first, and then the mesh can be hung before spraying the phosphogypsum slurry. When installing the keel, the top keel and the ground keel must be installed first, and then the vertical keel is installed between the top keel and the ground keel. The prior art can be found in Chinese patent application publication number CN111691586A.

[0003] Since the top keel is installed on the top slab or top beam, it is necessary to temporarily support the top keel before fixing it with multiple bolts. In construction environments where there are stairs blocking the side and trenches in the bottom floor slab, it is inconvenient to place support frames to temporarily support the top keel. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a top keel installation structure for phosphogypsum sprayed walls.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a top keel installation structure for a phosphogypsum sprayed wall, comprising: The top beam has a staircase on its side and a top joist on its underside. The staircase is fixedly connected to a vertical pipe, and a keel support arm supporting the top keel is fixed to the vertical pipe.

[0007] A steel pipe railing is fixedly installed on the side of the staircase near the top beam. The steel pipe railing is composed of vertical pipes and horizontal pipes that are fixedly connected by scaffolding steel pipe couplers A.

[0008] The vertical pipe is fixed with a scaffolding steel pipe coupler B, and the scaffolding steel pipe coupler B is welded and fixed with a keel support arm. The keel support arm supports the top keel with the scaffolding steel pipe coupler B as the load-bearing foundation.

[0009] The keel support arm includes a base foot that is welded and fixed to the scaffolding steel pipe coupler B, and the top of the base foot has a latch; an arm support is fixed to the side of the latch near the top keel.

[0010] The top opening of the bayonet is angled.

[0011] The arm support length L is greater than half the top keel groove width b and less than the top keel groove width b.

[0012] The connection between the arm support and the top of the base is a bevel.

[0013] A foam board is placed between the top keel and the bottom surface of the top beam, and the top keel and the foam board are fixed to the bottom surface of the top beam by multiple bolts.

[0014] The width of the top keel and foam board is smaller than the width of the top beam.

[0015] The beneficial effects of this utility model are as follows: the arm support takes the steel pipe railing on the side of the staircase as the force point, and after the top keel is temporarily supported by the arm support and contacts the top beam, multiple bolts are used in sequence and spaced apart to fix the top keel to the top beam. This solves the problem that it is inconvenient to place a support frame to temporarily support the top keel in construction environments where there are staircases blocking the side and trenches in the bottom floor slab.

Detailed Implementation

[0017] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0018] like Figures 1 to 3 As shown.

[0019] This application discloses a top joist installation structure for a phosphogypsum sprayed wall, comprising: There is a top beam 2 of the staircase 1 on the side, and a top keel 21 is installed on the top beam 2. There is a foam board 22 between the top keel 21 and the top beam 2.

[0020] A steel pipe railing 3 is fixedly installed on the side of the staircase 1 that is close to the top beam 2. The steel pipe railing 3 is composed of vertical pipe 31 and horizontal pipe 32, which are fixedly connected by scaffolding steel pipe coupler A (not shown in the figure).

[0021] The vertical pipe 31 is fixed with a scaffolding steel pipe coupler B4, and the scaffolding steel pipe coupler B4 is welded and fixed with a keel support arm 5. The keel support arm 5 temporarily supports the top keel 21 with the scaffolding steel pipe coupler B4 as the load-bearing foundation.

[0022] The keel bracket arm 5 includes a base foot 51 welded and fixed to the scaffold steel pipe fastener B4, the top of the base foot 51 is provided with a bayonet 52, the top opening of the bayonet 52 is a bevel opening, which facilitates the clamping fit between the bayonet 52 and the side edge of the top keel 21, at this time, the displacement of the top keel 21 along the ground of the top beam 2 is restricted, so as to realize supporting and positioning.

[0023] A bracket arm 53 is fixed on the side of the bayonet 52 close to the top keel 21, the length L of the bracket arm 53 is greater than half of the notch width b of the top keel 21 and less than the notch width b of the top keel 21, that is, b / 2<L<b, so that the bracket arm 53 can support the weight load of the top keel 21, and also facilitate the bracket arm 53 to be placed into the notch of the top keel 21.

[0024] The fixed connection part between the bracket arm 53 and the top of the base foot 51 is a bevel edge 54, which avoids interference with the inner surface of the notch of the top keel 21 if it is a straight edge.

[0025] The bracket arm 53 takes the steel pipe guardrail 3 on the side of the staircase 1 as the force bearing point, after the top keel 21 obtains temporary support through the bracket arm 53 and contacts the top beam 2, an electric drill is used to sequentially and fixedly connect the top keel 21 and the top beam 2 at intervals with a plurality of bolts 6, which solves the problem that in the construction environment where the side is blocked by a staircase and the bottom floor has a ditch body, it is inconvenient to place a support frame for temporarily supporting the top keel.

[0026] The top keel 21 and the foam board 22 are fixed on the bottom surface of the top beam 2 through a plurality of bolts 6; the widths of the top keel 21 and the foam board 22 are both smaller than the width of the top beam 2, so that after the subsequent wall spraying is completed, the sprayed surface can cover the top keel 21 and the foam board 22.
