Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building construction equipment, and particularly relates to a basement post-cast strip cover plate and mold. BACKGROUND

[0002] The traditional basement roof post-cast strip will reserve the position of the post-cast strip when pouring concrete, and the formwork can be removed only after the post-cast strip period. During the cleaning of the post-cast strip, the original concrete chiseling on both sides of the post-cast strip is often improper, there is a lot of construction waste, the reinforcement is bent, and the concrete pouring is often not proper, which often leads to an extension of the construction period, difficulties in on-site management, and safety hazards. There may also be a possibility of water stop steel plate falling off, water stop steel plate not being connected, improper pouring, and not being vibrated, which leads to quality problems such as the appearance of dark water after the post-cast strip roof is formed. The basement roof post-cast strip pre-sealing technology can effectively reduce the occurrence of water seepage and does not delay the development and construction of the next process, thereby saving time for the total construction period.

[0003] The basement roof post-cast strip pre-sealing is completed by covering a prefabricated cover plate on the upper side of the post-cast strip. The cover plate has a pouring hole in the center and a steel reinforcement frame embedded inside to improve the support strength. The concrete strength grade of the cover plate should be no less than C30, and the thickness should not be less than 100 mm. UTILITY MODEL CONTENTS

[0004] The utility model aims to provide a basement post-cast strip cover plate and mold for shortening the construction period and improving the construction effect.

[0005] To solve the above technical problems, the utility model is implemented by the following technical scheme:

[0006] A basement post-cast strip cover plate includes a plate body formed by pouring concrete. The plate body is of a rectangular structure. A horizontal steel reinforcement and a vertical steel reinforcement are embedded inside the plate body. The horizontal steel reinforcement and the vertical steel reinforcement are fixed by twisting at the corresponding intersection points by means of a wire. The vertical steel reinforcement has an extension section at each end of the plate body.

[0007] A pouring hole for pouring is reserved in the center of the plate body.

[0008] Further, a steel pipe is embedded in the inner side wall of the pouring hole. The steel pipe penetrates the plate body. A steel reinforcement groove is formed in the side wall of the steel pipe to accommodate the horizontal steel reinforcement and the vertical steel reinforcement on the side.

[0009] A mold for a basement post-cast strip cover plate includes a first guard plate at both ends of the vertical steel reinforcement. The first guard plate has a positioning groove to accommodate and support the end of the vertical steel reinforcement.

[0010] A second guard plate is located at the end of the horizontal steel reinforcement. After the second guard plate is spliced with the first guard plate, a frame is formed on the side of the enclosed plate body.

[0011] The first guard plate bottom is provided with a plurality of clamping grooves for clamping and slidingly fitting the upper side of the second guard plate.

[0012] The basement top plate waterproof construction and earthwork backfill work are carried out in the basement top plate waterproof construction and earthwork backfill work, and the problem of long-term non-closure of the post-pouring belt is solved.

[0013] In the process of building construction, the basement structure is applied more and more widely, and the construction process of prefabricated reinforced concrete plate is adopted in the construction process of post-pouring belt. BRIEF DESCRIPTION OF DRAWINGS

[0018] In the drawings, the component list represented by each sign is as follows: plate body 1, horizontal steel bar 11, vertical steel bar 12, steel pipe 2, steel bar groove 21, first guard plate 3, positioning groove 31, second guard plate 4, clamping groove 32, folding plate 41. DETAILED DESCRIPTION

[0019] The technical scheme in the embodiment of the utility model will be described clearly and completely in combination with the drawings in the embodiment of the utility model.

[0020] As Figs. 1-3The utility model provides a basement post-cast strip cover plate, including the plate body 1 formed by concrete pouring, the plate body 1 is rectangular structure, the plate body 1 inside is embedded with transverse reinforcement 11 and longitudinal reinforcement 12, and transverse reinforcement 11 and longitudinal reinforcement 12 are fixed by twisting through lashing corresponding intersection points, and longitudinal reinforcement 12 corresponds the extension section of both ends side of plate body 1,

[0021] Plate body 1 central reservation has the pouring hole for pouring, and the corresponding concrete strength grade of plate body should not be less than C30, and the thickness should not be less than 100mm.
