Abstract
Description
Technical Field
[0001] The utility model relates to a concrete pump pipe supporting structure of an assembled steel structure building foundation, belonging to the technical field of building concrete construction. Background Art
[0002] After the ribs are tied, the foundation of the prefabricated steel structure building needs to be poured with concrete for solidification. Since the foundation of the prefabricated steel structure building is in the foundation pit under the road, the pump truck cannot enter directly, so the concrete pump pipe is needed to transport the concrete to the construction point where it needs to be poured.
[0003] The concrete pump pipe needs to be supported above the spacer reinforcement during laying. The existing technology for supporting the concrete pump pipe is shown in Chinese Patent Publication No. CN110425342B. The fixing device provides stable force to support the concrete pump pipe through the concrete pier. However, the concrete pier has a large gravity, and it is not convenient to flexibly adjust it in the bundled reinforcement environment for support. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a concrete pump pipe support structure for an assembled steel structure building foundation.
[0005] The utility model is realized through the following technical solutions.
[0006] The utility model provides a concrete pump pipe support structure of an assembled steel structure building foundation, comprising:
[0007] gluten on the mold board;
[0008] An inverted triangular vertebra that can be deformed to support the concrete pump pipe is hooked in the ribs.
[0009] The reinforcement is formed by bundling cross-transverse reinforcements and longitudinal reinforcements.
[0010] The inverted triangular vertebra comprises three vertebrae edges which are inverted and intersected and fixed at the bottom. The vertebrae edges are fixedly connected to each other via connecting edges for supporting the concrete pump pipe, and the vertebrae edges at the intersection and fixation of the bottom are fixed with barbs.
[0011] The barb is hooked on the longitudinal reinforcement at the lower part of the rib.
[0012] The three vertebral edges can be elastically deformed to contact the transverse reinforcement.
[0013] The beneficial effect of the utility model is that the inverted triangular vertebra can be hooked on the longitudinal steel bar at the bottom of the ribs through the inverted hooks, so that it can be flexibly adjusted in the bundled rib environment to support the concrete pump pipe, which solves the problem that the concrete pier has a large gravity and is not convenient to be flexibly adjusted in the bundled rib environment to support it.

DETAILED DESCRIPTION
[0018] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.
[0019] like Figures 1 to 3 shown.
[0020] The present application discloses a concrete pump pipe support structure for a prefabricated steel structure building foundation, comprising:
[0021] The mold board 1 is constructed by using wooden boards, and the mold board 1 is cross-linked with transverse steel bars 12 and longitudinal steel bars 13 to form surface bars 11. A concrete pump pipe 2 for conveying concrete (also called concrete) is arranged on the surface bars 11. The concrete pump pipe 2 is supported in the surface bars 11 by a deformable inverted triangular cone 3.
[0022] The inverted triangular vertebra 3 includes a vertebral edge 31 formed of steel bars. The vertebral edges 31 are three and inverted so that the bottom is intersected and welded and fixed. The vertebral edges 31 are directly welded and fixed to each other through connecting edges 32. The connecting edges 32 support the concrete pump pipe 2. The vertebral edges 31 at the bottom intersection and fixed are welded and fixed with barbs 33. The barbs 33 can be hooked on the longitudinal steel bars 13 at the bottom of the ribs 11. After the three vertebral edges 31 are pressed down by the gravity of the concrete pump pipe 2, they are slightly elastically deformed and contact the transverse steel bars 12 at the top of the ribs 11, showing that the inverted triangular vertebra 3 is hooked on the ribs 11 to bear the force. The overall gravity of the ribs 11 balances the load of the concrete pump pipe 2 on the inverted triangular vertebra 3, thereby realizing the support of the inverted triangular vertebra 3 on the concrete pump pipe 2. At the same time, the inverted triangular vertebra 3 is hooked on the longitudinal steel bar 13 at the lower part of the rib 11 through the barb 33, so that it can be flexibly adjusted in the environment of the bundled rib 11 to support the concrete pump pipe 2, which solves the problem that the concrete pier has a large gravity and is not convenient to flexibly adjust in the environment of the bundled rib for support.
[0023] When the concrete pump pipe 2 pumps concrete (also called concrete) to the reinforcement 11 to accumulate the accumulation body 4. Utilize a concrete pouring construction equalizing tool to pull the accumulation body 4 to be evenly distributed around.
[0024] A concrete leveling tool 5 for concrete pouring construction of the present application comprises:
[0025] The concrete leveling rake plate 51 is cut from an arc-shaped steel plate, and the concrete leveling rake plate 51 is an inwardly concave arc-shaped body.
[0026] A rake rod 52 is welded and fixed to the top edge of the concrete leveling rake plate 51 , and the rake rod 52 is located in the middle of the top edge of the concrete leveling rake plate 51 .
[0027] The inner surface of the said concrete leveling rake plate 51 located at the rake rod 52 is welded and fixed with a side conductor A53 and a side conductor B54, both of which are conical, and the small ends of the conical side conductors A53 and B54 face outwards to guide the concrete when it is pulled and evenly distributed, thereby improving the effect of evenly distributing the concrete to both sides, and solving the problem that the rake plate as a whole is an arc-shaped inner concave body and has poor even distribution to both sides when the concrete is pulled by the rake rod. The side conductors A53 and B54 are symmetrically fixed on the inner surface of the concrete leveling rake plate 51 with the rake rod 52.
[0028] A reinforcing flow guide 55 is welded and fixed to the lower inner side of the concrete leveling rake plate 51 at the symmetrical position between the side conductor A53 and the side conductor B54, and the top of the reinforcing flow guide 55 is welded and fixed to the connection between the side conductor A53 and the side conductor B54; the reinforcing flow guide 55 guides the concrete when it enters the concrete leveling rake plate 51, and at the same time, the reinforcing flow guide 55 strengthens the concrete leveling rake plate 51.
[0029] The present invention provides a method for pouring concrete for a prefabricated steel structure building foundation, comprising the following steps:
[0030] Installation of concrete pump pipe 2: The concrete pump pipe 2 is hooked on the longitudinal steel bar 13 at the bottom of the rib 11 by the hook 33 of the inverted triangular vertebra 3 and flexibly adjusted for support; the problem that the concrete pier has a large gravity and is not convenient to flexibly adjust for support in the bundled rib environment is solved.
[0031] Concrete is transported by the concrete pump pipe 2: When the concrete is pumped from the pump truck into the concrete pump pipe 2 and transported to the surface reinforcement 11 to form a deposit 4, the worker uses the rake rod 52 with the concrete leveling rake plate 51 to pull and evenly distribute the concrete. When pulling and evenly distributing the concrete, the small ends of the conical side conductors A53 and B54 face outward to guide the concrete to both sides, thereby improving the effect of evenly distributing the concrete to both sides.
