Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a formwork for building construction. Background Technology

[0002] Construction is a production activity carried out by people using various building materials and machinery according to specific design blueprints within a certain space and time to build various types of building products. It includes the entire production process from construction preparation and groundbreaking to project completion and acceptance. This process involves construction preparation, construction organization design and management, earthwork, and other tasks. However, existing construction formwork supports have certain drawbacks. When in use, the support surface with the formwork is limited, resulting in a small support range and poor support effect for the formwork. Moreover, the support stability with the construction ground is also poor, making it impractical.

[0003] Publication (Announcement) No. CN222276163U discloses a formwork support frame for building construction, which can effectively expand the support surface of the formwork, improve the support effect of the formwork, enhance the support stability of the formwork frame, and improve its practicality. It includes a support rod, the bottom end of which is fixedly connected to a base plate. The outer circumference of the main support plate is provided with three sets of equidistant cross-sections, and each of the three sets of cross-sections is provided with an inward sliding groove. Three sets of sliding plates are slidably provided on the main support plate through the cooperation of the sliding grooves. Extension support plates are fixedly connected to the outer side of each of the three sets of sliding plates. The top end of the external threaded sleeve is connected to the bottom end of the main support plate. The top ends of the three sets of support strips are respectively hinged to the bottom ends of the three sets of extension support plates. A fixing ring is fixedly fitted on the support rod. Three sets of connecting strips are hinged equidistantly on the fixing ring. The bottom ends of the three sets of connecting strips are all horizontally fixedly connected to support plates. Fixing bolts are screwed onto each of the three sets of support plates.

[0004] While the above solutions can effectively expand the support surface of the template, the fixed support height of the equipment is relatively limited. Expanding the support components requires a large number of hinged and threaded parts, which makes the structure complex and the manufacturing cost high. Therefore, we propose a formwork for building construction. Utility Model Content

[0005] The main purpose of this utility model is to provide a formwork for building construction. By setting up a lifting unit and a support unit, it solves the problems of limited fixed equipment support height and the need for a large number of hinged and threaded parts to expand the support components, which result in complex structure and high manufacturing cost.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a formwork for building construction, including a bearing plate and a limiting component located on the bearing plate, and further including: a lifting unit and a support unit disposed on the bearing plate;

[0007] The lifting unit includes strip columns, vertical screws, support blocks, support vertical plates, and a storage box. Two strip columns are symmetrically fixed on the top surface of the bearing plate and are hollow inside. The vertical screw is movably mounted on the inner wall of one of the strip columns. There are two support blocks, which are located inside the two strip columns respectively. The two support vertical plates are fixed on the end faces of the two support blocks respectively. The storage box is fixed on the top of the two support vertical plates.

[0008] The support unit includes a horizontal lead screw, guide blocks, an extension plate, and anti-slip pads. The storage box has a movable through groove on each of its opposite sides. The horizontal lead screw is movably mounted on the inner wall of one end of the storage box. There are four guide blocks, which are divided into two groups. The two groups of guide blocks are symmetrically distributed inside the storage box. One group of guide blocks is respectively matched with the two symmetrically arranged positive and negative threads on the horizontal lead screw. An "L"-shaped extension plate is fixedly installed between every two guide blocks located on the same vertical center horizontal plane. Anti-slip pads are fixedly installed on the top surface of the extension plate and the top surface of the storage box.

[0009] Preferably, the lifting unit further includes a first guide rod, which is fixedly disposed inside another strip column and movably passes through another support block.

[0010] Preferably, the support unit further includes a second guide rod, which is fixedly disposed on the inner wall of the other end of the storage box and movably passes through another set of guide blocks.

[0011] Preferably, a turntable is fixedly provided on both the vertical lead screw end face and the horizontal lead screw end face.

[0012] Preferably, the limiting component includes a transverse sliding plate and a longitudinal strip plate. The top surface of the bearing plate has two symmetrically formed storage grooves. The storage grooves have strip-shaped sliding grooves on their opposite sides. The transverse sliding plate is movably mounted on the strip-shaped sliding grooves. The longitudinal strip plate is positioned at a height on the side of the transverse sliding plate. The top surface of the longitudinal strip plate has mounting holes.

[0013] Preferably, the horizontal sliding plate, the vertical strip, and the mounting holes are all arranged in a one-to-one correspondence with the storage groove.

[0014] Compared with the prior art, the formwork for building construction of this utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting up a lifting unit, by rotating the vertical screw in both directions outside the strip column, one of the support blocks threaded to the vertical screw can be driven by force to lift and adjust the support vertical plate inside the two strip columns. The storage box at the top of the two support vertical plates will expand and adjust its height accordingly. The other support block can slide and lift on the first guide rod to coordinate with the adjustment of the support vertical plate and the storage box and provide auxiliary support. The equipment has flexible support height expansion and adjustment and good applicability.

[0016] 2. In this utility model, by setting up a support unit, by rotating the transverse screw in both directions outside the storage box, two guide blocks that are symmetrically arranged with two sections of threads on the transverse screw will be driven by force to move relative to each other, which can drive two L-shaped expansion plates to adjust their spacing. The two expansion plates can be pulled out from the movable through slot to increase their exposed area on the storage box. The other two guide blocks can slide and translate on the second guide rod to cooperate with the adjustment of the expansion plates and provide auxiliary support. After the expansion plates are pulled out, the expansion plates and the anti-slip pads on the top surface of the storage box can expand the support surface to support the template. The operation structure of the equipment expansion support component is simple and the manufacturing cost is low. Attached Figure Description

The other two guide blocks 402 slide and translate on the second guide rod 405 to coordinate with the adjustment of the extension plates 403. After 403 is pulled out, the anti-slip pads 404 on the top surface of the expansion plate 403 and the storage box 305 expand the support surface to support the template. The vertical screw 302 rotates in both directions outside the strip column 301. One of the support blocks 303, which is threaded to the vertical screw 302, is subjected to force and drives the support vertical plate 304 to rise and fall inside the two strip columns 301. The storage box 305 at the top of the two support vertical plates 304 expands and adjusts its height accordingly. The other support block 303 slides and rises and falls on the first guide rod 306 to coordinate with the adjustment of the support vertical plate 304 and the storage box 305.
